Description

A foil splicing device for producing chemically formed foil

Technical Field

The invention relates to the technical field of chemically formed foil production equipment, and in particular to a foil splicing device used for producing chemically formed foil.

Background Art

Chemically formed foil is a product of specially made high-purity aluminum foil that undergoes electrochemical or chemical corrosion to expand its surface area, and then undergoes electrochemical formation to form an oxide film on the surface.

When producing formed foil, the aluminum foil will be unwound and slowly passed through each forming tank, and then formed in each forming tank in turn. The upper rolled aluminum foil needs to be connected with the lower rolled aluminum foil after unwinding. The existing foil connection method is roughly as follows: the tail end of the upper rolled aluminum foil and the head end of the lower rolled aluminum foil are overlapped on the foil connection platform, and the operator will use the foil connection hammer to knock intensively in the overlapping area to achieve the connection of the two rolls of aluminum foil. This has the following defects: 1. It is extremely dependent on the skill level and working status of the operator, and the quality of foil connection fluctuates; the training cycle for new employees is long; and the labor intensity is high. 2. When connecting the foil, the upper rolled aluminum foil needs to stop feeding, and aluminum foil is retained in each forming tank; the forming treatment parameters of these retained aluminum foils, especially the forming treatment time, are significantly different from those of the aluminum foil that was previously fed normally; this will lead to differences in the forming effect.

Summary of the invention

The object of the present invention is to provide a foil splicing device for producing chemically formed foil, which can ensure the quality of foil splicing, reduce labor intensity, and shorten the foil splicing time; and can make the upper rolled aluminum foil do not need to stop feeding when the foil is spliced, so that the chemical effect of the aluminum foil is more uniform and stable.

Optionally, the riveting mechanism also includes: a lifting seat driven by a riveting cylinder, and a bracket detachably connected to the bottom of the lifting seat; the bracket has a plurality of through holes passing through its upper and lower surfaces, and the through holes correspond one-to-one to the riveted parts; the riveted parts are installed in the through holes, and the top of the riveted parts has a cap portion limited between the bracket and the lifting seat.

Optionally, a clamping block is provided under the bracket, and the clamping block has a riveting hole for the passage of a riveting piece; the riveting cylinder is installed on the clamping block through a bracket; and the clamping block is adapted to be driven by a lifting cylinder to move it up and down.

The embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 5 .

The embodiment of the present invention provides a foil splicing device for producing chemically formed foil. The foil splicing device includes: a riveting mechanism located above a foil splicing platform 1, a first roller group 2 located on the left side of the foil splicing platform 1, a roller 3 located on the left side of the first roller group 2, and a third running mechanism 4 driving the roller 3 to move up and down. It should be understood that when the feeding device of the chemically formed tank drives the aluminum foil to feed to the left, the first roller group 2 and the roller 3 can be driven to rotate by the aluminum foil. The riveting mechanism includes a plurality of riveting parts 5 and a riveting cylinder 6 driving the riveting parts 5. The first roller group 2 includes a first active roller and a first driven roller connected in a transmission manner, and there is a gap between the first active roller and the first driven roller for the aluminum foil to pass. It should be understood that the first active roller can be driven by a servo motor, and the servo motor drives the first active roller to rotate forward or reverse, so that the aluminum foil can be conveyed to the left or right. The first active roller and the first driven roller are respectively coaxially fixed with a gear, and the two gears are meshed to form a transmission connection. The first roller group 2 is adapted to be equipped with a first braking mechanism. It should be understood that the structure of the first brake mechanism can refer to the brake of a car or a bicycle. In addition, the first brake mechanism can also be set as a brake member; the brake member is limited to the roller frame on which the first roller group 2 is installed, and can only move in the direction close to or away from the gear; the brake member is moved toward the gear and stuck in the tooth groove of the gear, so that the gear can be locked, thereby achieving the braking of the first roller group 2. The area between the first roller group 2 and the roller 3 constitutes a material storage area.

The specific implementation of the present invention is described below. When the upper roll of aluminum foil is almost finished, the first active roller is started to make the first roller group 2 quickly convey the aluminum foil to the left; and the third walking mechanism 4 drives the roller 3 to move upward, so that the remaining part of the upper roll of aluminum foil is suspended and stored in the storage area between the first roller group 2 and the roller 3. When the tail end of the upper roll of aluminum foil moves to the foil splicing platform 1 with the rapid conveyance of the first roller group 2, the first active roller is turned off, and the first roller group 2 is locked by the first brake mechanism, so that the tail end of the upper roll of aluminum foil can be fixed on the foil splicing platform 1; then the head end of the lower roll of aluminum foil is led to the foil splicing platform 1 and overlaps with the tail end of the upper roll of aluminum foil; finally, the multiple riveting parts 5 of the riveting mechanism are riveted at multiple points, so that the tail end of the upper roll of aluminum foil and the head end of the lower roll of aluminum foil are embedded together through the pits formed by riveting, thereby completing the foil splicing. During the foil splicing process, the formation tanks on the left side of the foil splicing device do not need to be shut down and can continue to feed materials; the roller 3 will gradually move downward under the drive of the third running mechanism 4, so as to provide the aluminum foil suspended and stored in the storage area to the formation tank on the left. The present invention drives multiple riveting parts 5 at a time through the riveting cylinder 6 to perform multi-point riveting on the overlapping part of the tail end of the upper roll aluminum foil and the head end of the lower roll aluminum foil to achieve foil splicing; compared with the foil splicing by manual single-point hammering, it has the advantages of short foil splicing time, stable foil splicing quality and low labor intensity. In addition, during the foil splicing process, the upper roll aluminum foil does not need to stop feeding, the formation processing parameters of the entire roll of aluminum foil are the same, and the formation effect of the aluminum foil is more uniform and stable.

In one embodiment disclosed in the present application, a second roller group 7 is provided on the right side of the foil splicing platform 1; the second roller group 7 includes a second active roller and a second driven roller in transmission connection, and a gap for the aluminum foil to pass through is provided between the second active roller and the second driven roller; the second roller group 7 is adapted to be equipped with a second braking mechanism. It should be understood that the structure of the second roller group 7 can refer to the first roller group 2, and the structure of the second braking mechanism can refer to the first braking mechanism, which will not be described in detail here.

Further, the first roller group 2 is adapted to be driven by a first running mechanism 8 for moving up and down, and the second roller group 7 is adapted to be driven by a second running mechanism 9 for moving up and down. It should be understood that when joining the foil, the first running mechanism 8 and the second running mechanism 9 can be used to drive the first roller group 2 and the second roller group 7 to move downward, so that the aluminum foil can be better attached to the surface of the foil joining platform 1. When feeding, the first running mechanism 8 and the second running mechanism 9 can be used to drive the first roller group 2 and the second roller group 7 to move upward, so as to avoid friction between the aluminum foil and the surface of the foil joining platform 1.

Furthermore, the first walking mechanism 8 is a linear motor or a lead screw driven by a servo motor; the first walking mechanism 8, the second walking mechanism 9, and the third walking mechanism 4 have the same structure.

In one embodiment disclosed in the present application, foil blocking members 10 are respectively provided on the left and right sides of the foil splicing platform 1; one end of the foil blocking member 10 is hinged to the foil splicing platform 1, and the other end can be rotated to a table surface higher than the foil splicing platform 1 under the action of external force. It should be understood that the foil blocking member 10 can be kept stationary by the friction force with the foil splicing platform 1. When splicing foil, the upper rolled aluminum foil is first quickly conveyed to the left by the first roller group 2, so that the tail end of the upper rolled aluminum foil completely falls on the foil splicing platform 1; then the first roller group 2 is locked by the first brake mechanism. Then, the foil blocking member 10 on the right side of the foil splicing platform 1 is rotated manually, by a motor or by rotating a cylinder, so that the end of the foil blocking member 10 away from the hinge is higher than the table surface of the foil splicing platform 1. Then the first brake mechanism is made to release the first roller group 2, and the first roller group 2 is made to convey the upper rolled aluminum foil to the right. When the right end of the upper rolled aluminum foil abuts against the foil stopper 10 on the right side of the foil splicing platform 1, the first roller group 2 is shut down, and the first brake mechanism is re-locked to complete the positioning of the tail end of the upper rolled aluminum foil. After the positioning of the tail end of the upper rolled aluminum foil is completed, the foil stopper 10 on the right side of the foil splicing platform 1 can be rotated to a level lower than the surface of the foil splicing platform 1. Next, the head end of the lower rolled aluminum foil is introduced into the second roller group 7; and the foil stopper 10 on the left side of the foil splicing platform 1 is rotated manually, by a motor, or by a rotating cylinder, so that the end of the foil stopper 10 away from the hinge is higher than the surface of the foil splicing platform 1. Then the second roller group 7 is made to convey the lower rolled aluminum foil to the left, so that the left end of the lower rolled aluminum foil abuts against the foil stopper 10 on the left side of the foil splicing platform 1; the second roller group 7 is shut down, and the second brake mechanism is re-locked to complete the positioning of the tail end of the lower rolled aluminum foil. During the entire positioning process, the operator does not need to contact the upper rolled aluminum foil, which is safer. In addition, if necessary, when the first roller group 2 or the second roller group 7 is conveying the aluminum foil, the operator can also place the end of the aluminum foil on the table of the foil splicing platform 1 through the insulating rod. The foil blocking member 10 can be set in a C shape or an L shape, so that when a sheet of aluminum foil is laid on the foil splicing platform 1, the end of the foil blocking member 10 away from its hinge can be rotated to the top of the aluminum foil to limit the other sheet of aluminum foil. The foil blocking member 10 can be made of insulating material.

It should be understood that by removing the bracket 12, the damaged riveted parts 5 can be replaced in a targeted manner, and the maintenance cost is lower.

Furthermore, a clamping block 13 is provided below the bracket 12, and the clamping block 13 has a riveting hole for the riveting piece 5 to pass through; the riveting cylinder 6 is installed on the clamping block 13 through a bracket; the clamping block 13 is adapted to drive the lifting cylinder 14 to move it up and down. It should be understood that when joining the foil, the clamping block 13 is firstly used to flatten the aluminum foil, and then the riveting cylinder 6 drives the riveting piece 5 to move downward for riveting; after the riveting is completed, the riveting cylinder 6 is firstly reset upward, and then the clamping block 13 is used to release the aluminum foil.

Furthermore, the lifting cylinder 14 is adapted to drive a fourth traveling mechanism 15 to move along the left-right direction; the fourth traveling mechanism 15 is a linear motor or a lead screw driven by a servo motor.

In one embodiment disclosed in the present application, a turning frame 16 is provided on the right side of the second roller group 7; the turning frame 16 is adapted with a power source 17 and is rotatably connected to a base 18; the turning frame 16 is installed with two material shafts 19 extending forward. It should be understood that the turning frame 16 is adapted with a third braking mechanism, and the power source 17 can be a stepper motor or a servo motor. The aluminum foil is usually placed on the material shaft 19 on the right side, and when the upper aluminum foil is about to be unrolled, the turning frame 16 is turned 180° to turn the upper aluminum foil to the left; that is, while unrolling the upper aluminum foil, the lower aluminum foil is placed on the newly turned right material shaft 19.

Furthermore, the front end of the material shaft 19 is supported on the support frame 20; the support frame 20 includes a chassis and a vertical portion; the chassis and the base 18 are provided with pin holes correspondingly, and are adapted to the positioning pin 21. It should be understood that the front and rear ends of the material shaft 19 are rotatably connected to the flip frame 16 and the support frame 20 through bearings respectively; in general, the material shaft 19 can rotate relative to the flip frame 16, but cannot move forward and backward relative to the flip frame 16. Pull out the positioning pin 21, pull out the support frame 20 forward, and then place the aluminum foil on the material shaft 19, or flip the flip frame 16.

Although specific embodiments of the present invention are described above, those skilled in the art should understand that various changes or modifications may be made to these embodiments without departing from the principles and essence of the present invention, and these changes and modifications are all within the scope of protection of the present invention.
