Abstract

This patent belongs to the field of sawing machine processing with circular saw blades, and specifically discloses a wood-like sticker process for door panels. Through a cutting device that can cut out narrow incisions, a number of glue removal grooves are cut in the longitudinal direction of the door panel for the sticker on the door panel. When it is finally squeezed, the excess glue is discharged from both ends of the glue discharge groove. And because the saw kerf that the device used in the plan can cut is extremely narrow, the glue removal groove is processed to be extremely narrow. When extrusion, because the ductility of the sticker itself is small, the extremely narrow glue removal groove will not deform the sticker. Because the glue removal groove is extremely narrow, it prevents the glue removal groove from affecting the appearance of the door panel.

Description

Door panel imitation wood sticker craft

technical field

The invention belongs to the field of sawing machine processing with circular saw blades.

Background technique

The door panel needs to be pasted with imitation wood stickers. In the prior art, glue is directly applied to the door panel, and then extruded to make the imitation wood sticker closely adhere to the surface of the door panel. However, when applying glue on the door panel, it is often uneven. Because the sticker is thin, when it is squeezed, the sticker will be uneven, or the imitation wood sticker will break. The reason is that the excess glue is sealed in the airtight space formed by the imitation wood sticker and the door panel during the extrusion process and cannot be discharged.

The inventor thinks that by processing the glue removal groove on the door panel, the excess glue can be discharged from both ends of the glue removal groove when the door panel is squeezed after the sticker. It is most convenient to use a saw blade or a circular saw to process the drainage groove, but the saw blade must have sufficient strength and not be too thin, especially when the saw blade cuts wood, it will generate high temperature and reduce the strength of the saw blade. In order to resist high temperature Deformation, the saw blade should increase a part of the thickness on the basis of meeting the normal temperature strength, so the thickness of the general saw blade or saw edge needs to be between 2.8-3mm.

Considering that the width of the drainage groove processed by a 2.8-3mm saw blade is about 3-4.5mm, and the imitation wood sticker has a certain degree of ductility. Wide, the pressure makes the imitation wood sticker concave, affecting the effect of the sticker. Moreover, the number of liquid drainage grooves to be processed is large, and the width of the processed liquid drainage grooves is relatively wide, which will affect the appearance of the door panel and reduce sales.

Contents of the invention

The purpose of the present invention is to provide a door panel imitation wood sticker process to solve the problem that excess glue is sealed in the closed space formed by the imitation wood sticker and the door panel and cannot be discharged during the extrusion process.

In order to solve the above problems, the present invention provides a door panel imitation wood sticker process, comprising the following steps:

S1. Using the door panel deglue groove processing equipment, process 40-50 deglue grooves on the upper surface of the door panel and the lower surface of the door panel along the length direction of the door panel, and the width of the deglue groove is 1-1.5mm; the door panel deglue groove Processing equipment including a first horizontal conveyor, a second horizontal conveyor, a slotting device and a vertical conveyor for changing door panels from the first horizontal conveyor to the second horizontal conveyor, the vertical conveyor including a platform, the platform below A hydraulic cylinder is provided; the first horizontal conveying device and the second horizontal conveying device are respectively located above and below the slotting device, and the cutting device includes a first motor, a disc, a liquid storage tank and several sawtooth units, and the center of the disc is connected At the output end of the motor, the sawtooth units are distributed on the circumference of the disc. There is a cavity in the disc, which is connected to the liquid storage tank. There is a one-way connection between the cavity and the liquid storage tank. There is an accumulator in the liquid storage tank, and an overflow valve in the cavity; the sawtooth unit includes a hydraulic cylinder, the piston rod of the hydraulic cylinder is provided with a pressing part with a slope, and the pressing part is provided with sawtooth, and the hydraulic cylinder communicating with the cavity;

S2. remove the burrs on the surface of the door panel, and clean the surface of the door panel;

S3. Brush the environmental protection glue on the door panel, paste the imitation wood sticker, put it into the drying extrusion machine, and press out the excess environmental protection glue between the imitation wood sticker and the door surface;

S4. Remove the excess environmental protection glue discharged through the glue discharge groove on the edge of the door.

The beneficial effect of this basic scheme is that: this scheme makes the surface of the door panel smooth by processing the glue removal groove on the door panel, and then removing the burrs left during the processing of the door panel. Then paste the imitation wood sticker, put the door panel into the drying press, make the imitation wood sticker and the door panel flat, dry the glue, and finally remove the residual glue on the door panel. The whole technological process is simple and easy to operate.

By cutting a number of glue discharge grooves in the longitudinal direction of the door panel, when the door panel is squeezed after pasting, the excess glue will be discharged from both ends of the glue discharge groove, which prevents the glue from being unable to discharge during extrusion, resulting in uneven stickers on the door panel.

And because the saw kerf that the device used in the scheme can cut is extremely narrow, the glue removal groove is processed to be extremely narrow. When extrusion, because the ductility of the sticker itself is small, the extremely narrow glue removal groove will not deform the sticker.

Because the glue removal groove is extremely narrow, it prevents the glue removal groove from affecting the appearance of the door panel.

Further, after step S4, the following step is also included: the following step is also included: placing in a cool and dry place for 3-5 days. Leave it for 3-5 days to remove the smell of environmental glue.

Further, the overflow valve is located at the center of the disc, and the overflow valve located in the disc at the end of the output end of the motor is provided with a universal joint, and a hose is connected to the universal joint. The setting of the hose guides the discharged hydraulic oil to the position farther away from the inner saw blade to prevent the coolant from sticking to the sawtooth unit, so that the wood sticks to the coolant and affects the quality of the door panel. Further, the working part of the sawtooth is an arc-shaped surface. The arc-shaped working part also enables the sawtooth unit to retract the piston rod while contacting the wood.

Further, the cavity is a spiral channel. Spiral channels are distributed in the disc to make the heat dissipation area larger.

The basic scheme of embodiment: the imitation wood sticker technology of door panel in this scheme, comprises the following steps:

S1. Utilize the door panel glue removal groove processing equipment to process 40 glue removal grooves on the upper surface of the door panel and the lower surface of the door panel along the length direction of the door panel, and the width of the glue removal groove is 1 mm; the door panel glue removal groove processing equipment is shown in Figure 1 As shown, it includes a first horizontal transport device 1 , a second horizontal transport device 4 , a slotting device and a vertical transport device 3 for changing the door panel 2 from the first horizontal transport device 1 to the second horizontal transport device 4 . The first horizontal transport device 1 includes a first hydraulic cylinder, the first clamp for clamping the door panel 2 is installed on the output end of the first hydraulic cylinder, and the second horizontal transport device 4 includes a second hydraulic cylinder, the output of the second hydraulic cylinder A second clamp for clamping the door panel 2 is installed on the end. The vertical transport device 3 comprises a platform, and a hydraulic cylinder is installed under the platform; the first horizontal transport device 1 and the second horizontal transport device 4 are respectively positioned above and below the slotting device, and the slotting device includes a motor and several saw assemblies, and the saw assembly includes The disc 10, the liquid storage tank and some sawtooth units, the sawtooth unit comprises the disc 10, the liquid storage tank and some sawtooth units, the center of the disc 10 is connected to the output end of the motor, and the sawtooth units are distributed on the circumference of the disc 10, the circle A spiral cavity 9 is integrally formed in the disk 10, and the cavity 9 communicates with the liquid storage tank. A one-way valve from the liquid storage tank to the cavity 9 is installed between the cavity 9 and the liquid storage tank. There is an accumulator, a liquid filling pump is connected to the liquid storage tank, and an overflow valve is installed in the cavity 9, and the overflow valve is located in the center of the disc 10, and is located on the overflow valve 10 in the disc at the end of the motor output end A universal joint is provided, and a flexible pipe is connected to 6 on the universal joint, and the flexible pipe leads to the liquid receiving bucket. As shown in Figure 2 and Figure 3, the sawtooth unit includes a third hydraulic cylinder, the piston rod 7 of the third hydraulic cylinder is processed with a pressing part 8, the bottom of the pressing part 8 is an arc surface consistent with the circumference of the disc 10, and the pressing part Sawtooth 5 is integrally formed on 8, and a working portion with a slope is processed on the serration 5, and the hydraulic cylinder communicates with cavity 9. Wherein, the working portion of the sawtooth 5 is an arc-shaped surface, which also has the same effect.

The saw tooth length used is 5mm, the thickness is 0.8mm, the disc radius is 500mm, and the piston rod length is 10mm. During processing, the distance between the door surface and the center of rotation of the disc is 502mm. Before work, add coolant in the liquid storage tank and the cavity 9, and the coolant in the cavity 9 and the pressure cylinder will cool the saw. Make the edge of the first clamp door panel 2, and the first horizontal transport device 1 transports the door panel 2 above the slotting device, and the slotting device cuts a drainage groove on the lower surface of the door panel 2. After the glue removal groove on the lower surface of the door panel 2 is processed, loosen the first clamp, and use the vertical transport device 3 to change the door panel 2 from the first horizontal transport device 1 to the second horizontal transport device 4, and the second hydraulic cylinder extends , the second clamp clamps the edge of the column door, and transports the door panel 2 to the lower part of the cutting device. Because the first horizontal conveying device 1 and the second horizontal conveying device 4 are respectively located above and below the slotting device, the third hydraulic cylinder moves the platform, moves down with the door panel 2, and makes the upper surface of the door panel 2 always face On the top, the working part below the cutting device can be used for processing the upper surface of the door. As shown in Figure 4, when the slotting device is working, the sawtooth unit is in contact with the wood, because the sawtooth 5 has an inclined surface, and the inclined or arc-shaped surface of the sawtooth 5 acts on the wood, so that the piston rod 7 is thrust axially, and the piston rod 7 shrinks. back. At this time, the pressing part 8 is in close contact with the pressure cylinder, and does not move any more, so that the sawtooth unit has the cutting ability. After the piston rod is retracted, the distance between the center of the disc and the surface of the door panel is 502mm, and the distance between the center of the disc and the tip of the sawtooth is 505mm, that is, the processing depth of the glue removal groove is 3mm. Simultaneously because of the effect of the one-way valve, when the piston retracts, only the pressure in the cavity 9 increases, and the pressure in the cavity 9 increases to make the overflow valve work, and discharge a part of the cooling liquid with higher temperature. When a sawtooth unit completes the sawing process and there is no load, due to the action of the accumulator in the liquid storage tank, the coolant with a lower temperature in the liquid storage tank enters the cavity 9 through the one-way valve, and pushes the piston rod 7 up. out. At this time, the sawtooth unit has no cutting ability. In this way, the sawtooth unit completes one cycle of action. During this process, the liquid filling pump continuously adds coolant to the liquid storage tank to keep the equipment working continuously. The coolant with higher temperature is discharged from the overflow valve and enters the liquid receiving barrel through the hose. When the scheme is working, a part of the sawtooth units that are in contact with the wood is in a compressed state, and the other part of the sawtooth units that are not in contact with the wood is in a protruding state. As the disc 10 rotates, the sawtooth units that are in contact with the wood are no longer in contact with the wood, and the units that are not in contact with the wood start to be in contact with the wood. That is to say, in the working process of the sawtooth 5 unit on the disc 10 there is always a part of the sawtooth 5 retracted and the other part extended, and the states of the two parts of the sawtooth unit alternate with the rotation of the disc 10 . The states of the two parts of the sawtooth unit alternate with each other so that the coolant with higher temperature is continuously discharged, and the coolant with lower temperature is continuously entered into the cavity 9, so that the temperature of the saw assembly is always kept low, thereby ensuring that the sawtooth will not break.

S2. remove the burr on the door surface, and clean the surface of the door;

S3. Brush the environmental protection glue on the door panel, paste the imitation wood sticker, put it into the drying extrusion machine, and press out the excess environmental protection glue between the imitation wood sticker and the door surface;

S4. Remove the excess environmental protection glue discharged through the glue discharge groove on the edge of the door.

S5. Store in a cool and dry place for 5 days.

Based on the basic scheme of the above examples, some data were adjusted for experimentation. The experimental data are as follows:

In the experiment, the SFG-1 surface roughness tester was used to measure the door panels pasted with imitation wood stickers. The test was divided into five groups, with 10 door panels in each group, and the results were averaged. The flatness of the imitation wood sticker itself is determined to be 1.2. From the comparison of Examples 1 and 2, it can be seen that the glue removal groove can improve the flatness of the door panel after the sticker. From Examples 1 to 5, it can be seen that the more the glue removal groove is, the higher the flatness of the door panel after the sticker is, but After increasing to 40, the change of flatness is not obvious after continuing to increase. From Examples 1 to 5, it can be seen that the deeper the depth of the glue removal groove, the higher the flatness, but when the processing depth reaches 3, the change in the flatness is not obvious after further deepening. Therefore, considering the equipment cost, it is preferable to process 40 strips on the door panel. Glue removal groove, the processing depth of the glue removal groove is 3mm.
