Description

Welding machine for synthetic resin

The present invention relates to a synthetic resin welding machine, and more specifically, to a synthetic resin welding machine that enables welding using hot air and ultrasonic vibration energy, while allowing smooth entry and exit of fabric between an upper welding roller made of metal and a lower ultrasonic horn.

Recently, as leisure and hobby activities have become more active, various functional clothing, coverings, tents, etc. are being widely used.

Fabrics for various types of clothing, etc., are usually required to have a basic waterproof function, and are produced using waterproof fabrics that have a waterproof function.

Accordingly, fabrics that require waterproofing, such as functional clothing, coverings, tents, etc., are manufactured using the above waterproof fabrics so that they faithfully perform their original function while also allowing protection against rainy weather due to their waterproof function.

Accordingly, the waterproof fabrics as described above can secure their waterproof properties by joining them together through welding, and among the welding methods, the heat welding method is mainly used.

Meanwhile, hot air, ultrasonic, high-frequency, rotation, and vibration welding methods are being applied as thermal welding methods.

Among these, hot air welding is mainly used to bond waterproof tape to the sewing part of fabric. High temperature hot air is applied to the waterproof tape to melt it to a predetermined degree, and at the same time, the waterproof tape is bonded to the sewing part of the fabric and passed between upper and lower rollers made of rubber.

However, the hot air welding method described above is one in which high-temperature hot air is discharged over a relatively large area, and while it was possible to melt and bond relatively thin waterproof tapes, there was a serious problem in that when thick fabrics such as tents were overlapped and bonded, the waterproof coating surface around the bonding surface of the fabrics burned and peeled off due to excessive hot air.

In particular, in the past, general PE, PVC coating materials were used for waterproofing tents, etc., but recently, polymer coatings made of environmentally friendly materials are being applied to prevent environmental pollution. However, in the case of the hot air mentioned above, if weak hot air is applied, the decomposition power of the polymer decreases, preventing proper bonding, and if excessive hot air is applied, there was a problem that the coating surface burned.

Accordingly, in order to solve the above problems, an ultrasonic welding method is applied in which ultrasonic vibration energy is transmitted to the welding material through an ultrasonic horn, causing a momentary frictional heat to be generated at the joint surface of the welding material between the upper welding roller and the welding material, thereby melting and bonding the synthetic resin to form a strong molecular bond.

However, the conventional welding method using a welding roller and an ultrasonic horn as described above has a problem in that the welding wheel and the ultrasonic horn are both made of metal, and when a strong fabric enters, the frictional force is reduced, causing the fabric to slip, making it difficult to properly enter and discharge the fabric, and this has caused a serious problem in that uniform welding work cannot be performed.

Republic of Korea Patent No. 10-2088557. Republic of Korea Patent No. 10-2405061.

The present invention has been made to solve the above-mentioned problems, and the purpose of the present invention is to provide a synthetic resin welding machine that enables uniform welding work by configuring an entry friction roller made of a rubber material that rises and falls from the bottom to the top of a worktable, thereby allowing the welding roller to descend to grab the fabric and, during the rotation process, providing frictional force with the entry friction roller to facilitate the entry and discharge of strong fabric.

In addition, the purpose of the present invention is to provide a synthetic resin welding machine that configures a discharge guide roller and a friction roller made of rubber having frictional force with the discharge guide roller at the rear of a worktable, thereby pulling the fabric from the rear during the discharge process to enable smooth discharge.

As a specific means for achieving the above purpose, a main body is formed with a work table formed with a horn extraction hole and a fabric support bar on one side of the middle portion, and a support arm formed with a horizontal protrusion toward the upper portion of the work table and an upper guide formed at the front to guide the entry of the fabric from the upper portion;

A rotary driving means formed on the bottom surface of the above worktable, comprising a driving motor and a rotary shaft, the rotary shaft being connected to the ultrasonic generator by a belt pulley to provide rotary force to the ultrasonic generator;

A lower guide formed at the upper front of the above worktable to guide the entering fabric from below;

An entry guide means that operates by forming and releasing holes in the lower part of the work table and applying rotational frictional force to the welding roller to control the entry and exit of the fabric; and

It is configured to include a discharge guide means formed on the work table and support arm at the rear side of the work table and provides discharge force to the fabric discharged to the rear.

It is configured to include a stroke adjustment bolt that is vertically screwed to the above installation bracket and is supported on the upper part of the rotation table when the rotation table is operated to adjust the rotation angle.
This can be achieved by configuring the rotational motion of the rotary table through the operation of the above cylinder so that the entry friction roller protrudes from the upper part of the ultrasonic horn or is drawn into the lower part.

As described above, the synthetic resin welding machine of the present invention is configured with an entry friction roller that rotates up and down on both sides of a lower ultrasonic horn, so that when a high-quality fabric is entered, smooth entry is possible due to rotational friction between the upper welding roller and the entry friction roller, and thus, the effect of uniform welding work can be obtained.

In addition, a discharge guide roller and a friction roller are configured at the rear of the work table, so that a rotational friction pulling from the rear can be applied, thereby achieving the effect of guiding the smooth discharge of the fabric.

And, the lower fabric entry plate (620) is provided with a plurality of holes (622) spaced at regular intervals on the left and right, and bolts (B) are fastened and fixed through the holes (622).

Accordingly, the lower fabric to be welded can be stably inserted with one side thereof entering and being supported in the lower fabric entry groove (621).

The above-mentioned entry guide means (700) provides frictional force with the fabric to be welded when configuring the synthetic resin welding machine (1) of the present invention, thereby facilitating the entry and discharge of the fabric for welding work.

In addition, the entry guide means (700) is configured with a pivot (720), and one end of the pivot (720), that is, the front end, is connected to the lower end of the installation bracket (710) by a hinge (721) so that the front can rotate up and down.

In addition, the entry guide means (700) is configured with a cylinder (730), and the cylinder (730) is configured to be vertically mounted on the installation bracket (710), and a cylinder rod (731) is configured to vertically extend and extend downward, but the cylinder rod (731) is configured to be connected to the middle of the pivot (720) so as to control the up and down rotation of the pivot (720) by the extending and extending operation.

In addition, the entry guide means (700) is configured with a pair of roller mounting bars (740) symmetrically arranged on both sides, and the roller mounting bars (740) are configured to have a bent bar shape, with one end connected to the rear end of the pivot (720) and the other end configured to protrude rearwardly toward the horn extraction hole (111), and are configured to be arranged on both sides of the ultrasonic horn (430).

In addition, the entry guide means (700) is configured with an entry friction roller (750), and the entry friction roller (750) is configured to be vertically installed at the rear end of each roller mounting bar (740) and rotated by friction with the fabric.

Accordingly, the entry guide means (700) is configured such that when the cylinder rod (731) is withdrawn by the operation of the cylinder (30), the rotation table (720) is rotated and the rear end of the roller mounting bar (730) is rotated downwards so that the entry friction roller (750) is hidden in the horn extraction hole (111), and when the entry is withdrawn, the rotation table (720) is rotated so that the entry friction roller (750) protrudes a predetermined amount above the horn extraction hole (111) and the upper portion of the ultrasonic horn (430), and when the welding roller (210) is lowered, it presses to forcibly draw in the cylinder rod (731) so that its circumference forms the same plane as the circumference of the ultrasonic horn (430).

The above discharge guide means (800) enables stable discharge of the welded fabric during the discharge process when configuring the synthetic resin welding machine (1) of the present invention.

To this end, referring to Fig. 10, the discharge guide means (800) is first configured with a discharge guide roller (810), and the discharge guide roller (810) is configured to be rotatable by being installed at the rear of the work table (110) with a left-right length.

At this time, the discharge guide roller (810) is configured to be rotatable by the rotation driving means (500), and for this purpose, it is configured to be connected to the rotation shaft (520) of the rotation driving means (500) by a belt pulley (522).

That is, the discharge guide roller (810) provides rotational force to the ultrasonic generator (400) through the rotational shaft (520) of the rotational driving means (500), and has the same rotational force as the ultrasonic generator (400), so that the welding work and discharge are performed in the same manner.

In addition, the discharge guide means (800) is configured with a rotating shaft (820), and the rotating shaft (820) is installed at the rear of the support arm (120) through a bracket (821) or the like so as to be rotatable parallel to the discharge guide roller (810).

In addition, the discharge guide means (800) is configured with a cylinder (830), and the cylinder (830) is vertically mounted at the rear center of the support arm (120) and is configured to have a cylinder rod (831) that operates to extend downward.

At this time, the cylinder rod (831) is configured such that its lower end is connected to the rotary shaft (820) through a connecting member (832), and is configured to prevent the forward and reverse rotation of the rotary shaft (820) during the launching operation.

In addition, the discharge guide means (800) is configured with a rotary friction means (840) that interferes with the discharge guide roller (810) to provide a rotary frictional force to enable smooth discharge of the fabric. The rotary friction means (840) are configured in multiples with a constant left and right interval.

At this time, the rotary friction means (840) is first configured with a connecting bracket (850), and the connecting bracket (850) has a form that is open toward the bottom, the rear end is fixedly mounted to the rotary shaft (820), and spring hooks (851) are configured to protrude on both sides in the front.

In addition, a mounting bar installation groove (852) is cut into the front of the connecting bracket (850) so that a roller mounting bar (860) described later can be mounted.

And, the roller mounting bar (860) has a spring connecting plate (862) corresponding to the spring hook (851) formed in the middle thereof.

And, the roller mounting bar (860) is provided with a protruding catch (863) that catches the connecting bracket (850) at the upper rear portion thereof and prevents the lower rotation of the roller mounting bar (860).

In addition, the rotating friction means (840) is configured with a discharge friction roller (870). The discharge friction roller (870) is configured with a rubber material to have frictional force, and is configured to be rotatably installed on the tip of the roller mounting bar (860).

Accordingly, the discharge guide means (800) is configured such that the rotating shaft (820) rotates by the operation of the cylinder (830), and when the roller mounting bar (860) of the rotating friction means (840) rotates downward by the one-way rotation, the discharge friction roller (870) comes into contact with the discharge guide roller (810) and provides a rotational frictional force to the discharge guide roller (810). At this time, the tension spring (880) is configured to provide tension so that the discharge friction roller (870) comes into contact with the discharge guide roller (810).

Hereinafter, the operation of the synthetic resin welding machine of the present invention having the above configuration will be described in detail with reference to the attached drawings.

Referring to FIGS. 1 to 10, the synthetic resin welding machine (1) of the present invention enables smooth welding during the process of overlapping rigid fabrics and welding them with hot air and ultrasonic waves, while facilitating the entry and exit of the fabrics without slipping, and thereby enabling uniform welding operations.

To this end, first, the fabric to be entered for welding operation is composed of an upper fabric (10) and a lower fabric (20). At this time, the upper fabric (10) is guided into entry through an upper guide (130), and the lower fabric (20) is guided into entry through a lower guide (600).

Referring to Fig. 11, first, the upper fabric (10) is inserted into the upper fabric entry groove (213) formed in the upper fabric entry plate (134) while being placed on the fabric support bar (112) and supported on one side before being inserted.

And the lower fabric (20) is inserted into the lower fabric entry groove (621) formed in the lower fabric entry plate (620) and supported on one side so that it can be entered, so that the upper fabric (10) and the lower fabric (20) form a state where the vertical welding portions overlap.

In particular, in the present invention, the upper fabric entry plate (134) is controlled to move left and right by the control block (133), and the lower fabric entry plate (620) is controlled to slide left and right from the rail member (610), so that it can be adjusted according to the degree of overlap of the fabric to be welded or the thickness of the welding roller (210) and the ultrasonic horn (430).

Thereafter, a welding operation for joining the upper and lower fabrics (10)(20) that are introduced as described above is performed. This is done by operating the synthetic resin welding machine (1), rotating the heater rod (310), lowering the welding roller (210), rotating the ultrasonic generator (400), and operating the entry guide means (700) and the discharge guide means (800).

That is, referring to Fig. 12, the upper and lower fabrics (10) (20) are overlapped and inserted between the welding roller (210) and the ultrasonic horn (430) according to the operation described above.

Accordingly, the upper and lower fabrics (10)(20) are heated by hot air discharged from the hot air nozzle (311) of the heater rod (310).

Thereafter, the upper and lower fabrics (10)(20) that are introduced are introduced between the welding roller (210) and the ultrasonic horn (430) and at the same time, are melted and pressurized by frictional heat caused by ultrasonic vibration energy between the welding roller (210) and the ultrasonic horn (430).

At this time, in the present invention, the supplied upper and lower fabrics (10) (20) can be entered and discharged by the opposite rotational force of the welding roller (210) and the ultrasonic horn (430), so that welding work of the upper and lower fabrics (10) (20) becomes possible.

Meanwhile, as described above, when the upper and lower fabrics (10)(20) enter and exit between the welding roller (210) and the ultrasonic horn (430), the welding roller (210) and the ultrasonic horn (430) may not enter and exit properly due to a slipping phenomenon when working with strong fabrics due to the characteristics of being composed of metal.

Accordingly, in the present invention, friction with the lower fabric (20) is applied by the entry guide means (700), and in the entry guide means (700), the front of the rotating table (720) and the roller mounting bar (740) is rotated upward by the operation of the cylinder (730) to cause the entry friction roller (750) to protrude above the horn extraction hole (111).

At this time, the protruding entry friction roller (750) initially protrudes above the ultrasonic horn (430), but as the welding roller (210) descends, it presses the entry friction roller (750), so that the peripheral surface of the entry friction roller (750) comes into contact with the lower peripheral surface of the welding roller (210) along with the predetermined inlet operation of the cylinder rod (731) of the cylinder (730).

Accordingly, when the upper and lower fabrics (10)(20) enter, the rubber entry friction roller (750) applies a predetermined amount of pressure to the bottom surface of the lower fabric (20), so that frictional force is applied to the lower fabric (20), enabling stable entry and rearward discharge of the welded upper and lower fabrics (10)(20).

In addition, in the present invention, smooth discharge is possible when the upper and lower fabrics (10)(20) are discharged to the rear in a welded state as described above, and this is possible by the discharge guide means (800).

This means that, with reference to Fig. 13, in the discharge guide means (800), when the synthetic resin welding machine (1) is in operation, the rotating shaft (820) is rotated by the operation of the cylinder (830) and the rotating friction means (840) is mounted.

That is, when the rotating shaft (820) of the rotating friction means (840) rotates, the connecting bracket (850) and the roller mounting bar (860) rotate downward. At this time, the discharge friction roller (870) comes into contact with the upper portion of the discharge guide roller (810), but comes into contact with tension due to the operation of the tension spring (880).

At this time, the discharge guide roller (810) is configured to have the same rotational power as the ultrasonic generator (400) by the rotational driving means (500), so that when the upper and lower fabrics (10) (20) to be welded and discharged enter between the discharge guide roller (810) and the discharge friction roller (870), the upper and lower fabrics (10) (20) are pulled at the same speed as the welding speed and discharged to the rear.

In addition, in the present invention, when welding and joining upper and lower fabrics (10)(20) using the ultrasonic horn (430) and the welding roller (210) as described above, excessive heat may be generated in the ultrasonic horn (430) other than the welding operation due to high temperature frictional heat caused by ultrasonic vibration energy. In this case, in the present invention, predetermined cooling of the ultrasonic horn (430) is possible by the cooling unit (1000).

This means that, with reference to FIG. 8, air supplied to the air supply pipe (1010) moves and is distributed to the air distribution pipe (1020) and is discharged to the side of the ultrasonic horn (430) through the air discharge hole (1021)(1021'), thereby enabling cooling of unnecessary heat generated outside the peripheral surface of the ultrasonic horn (430) required for welding.

As described above, the synthetic resin welding machine of the present invention enables stable entry and exit by applying rotational frictional force through the entry guide means and the exit guide means when welding a strong fabric, thereby enabling uniform welding during the welding of the fabric.
