Description

Technical Field

[0001] The utility model relates to the technical field of plastic edge banding processing equipment, and specifically, to a plastic edge banding anti-jumping device. Background Art

[0002] In the furniture manufacturing industry, the edge banding process is a crucial link. It can not only protect the edges of furniture from wear, improve the service life of furniture, but also enhance the overall aesthetics of furniture. The traditional edge banding process usually uses hot melt adhesive to paste plastic edge banding to the edges of furniture boards, and this process needs to be completed by an edge banding machine.

[0003] In the prior art, the authorized announcement number is: CN220297183 U, and the name is: a plastic edge banding anti-jumping device. This utility model relates to the technical field of plastic edge banding processing, and discloses a plastic edge banding anti-jumping device, including a processing table. A feeding mechanism is arranged inside the top end of the processing table, a cutting mechanism is arranged in the middle of the top end of the processing table, and a limiting and positioning mechanism is arranged on the top end of the processing table. For this plastic edge banding anti-jumping device, by setting the limiting and positioning mechanism, the sliding telescopic rod can be retracted into one end inner side of the limiting rod to drive the limiting clamping plate to move and open. After the plastic edge banding body moves to the middle of the limiting clamping plate, the telescopic rod is released, and the telescopic rod is forced to rebound and reset to extend by the reaction force of the spring to drive the limiting clamping plate to move and close to clamp and limit the plastic edge banding body in the middle, so as to effectively facilitate the limiting and positioning of plastic edge banding bodies of different sizes, avoid the plastic edge banding body being prone to jump and shift under force, and cause the cutting process to be affected. However, this technology cannot solve the jumping during the adhesion of the edge banding to the board, and at the same time, this technology is only suitable for small-sized boards and cannot adapt to the sizes of most boards on the market.

[0004] Furthermore, during the operation of the existing edge banding machines, there are also problems of inaccurate edge banding positioning. During the edge banding process, the edge banding needs to move accurately along the edge of the board. However, due to the relatively soft material of the edge banding, it is prone to offset or jump during high-speed movement due to insufficient friction or external factors (such as the unevenness of the board, the vibration of the edge banding machine, etc.), resulting in inaccurate edge banding. There is also a problem of pressure control for the edge banding. The edge banding needs to apply a certain pressure during edge banding to ensure that the glue can fully penetrate and adhere firmly. However, the existing edge banding machines often have difficulty in accurately controlling the pressure of the edge banding. Excessive pressure will cause the edge banding to deform, and too little pressure may result in weak adhesion. Summary of the Utility Model

The top of the base 1 is welded and connected with a first fixing plate 2, and the top of the base 1 is welded and connected with a second fixing plate 3. The first fixing plate 2 is on the upper side of the second fixing plate 3. The top of the first fixing plate 2 is welded and connected with a tape plate 4. The upper end surface of the tape plate 4 is connected with a tape shaft 5 through a bearing. An inlet 6 is arranged through the middle of the first fixing plate 2. A first heating roller 7 is connected to the inside of the inlet 6 through a bearing. A conveying wheel 8 is connected between the first fixing plate 2 and the second fixing plate 3 through a bearing.

[0025] As Figures 1 to 5 shown, the pressing mechanism 12 includes a threaded rod 13, a nut 14, a pressing block 15, a second heating roller 16, a first pressing roller 17, a second pressing roller 18 and a spring 19. The middle of the first fixing plate 2 is slidably connected with a threaded rod 13. The bottom of the threaded rod 13 is connected with a pressing block 15 through a screw. A second heating roller 16, a first pressing roller 17 and a second pressing roller 18 are connected to the inside of the pressing block 15 through bearings. A spring 19 is arranged between the upper side of the pressing block 15 and the lower side of the first fixing plate 2. The top of the threaded rod 13 is threadedly connected with a nut 14. The arrangements of the first heating roller 7 and the second heating roller 16 can heat the edge banding, soften the plastic, make it easier to fit the edge of the plate 20, and at the same time solve the jumping problem caused by the internal stress of the edge banding. The pattern design on the surfaces of the first pressing roller 17 and the second pressing roller 18 increases the friction with the plastic edge banding, prevents slipping during the pressing process, and ensures accurate positioning of the edge banding.

[0026] As Figures 1 to 5As shown in the figure, in order to prevent the edge banding strip from shifting or jumping during pressing, the auxiliary wheel 11 is made of soft rubber material, which can better fit the board 20 and avoid the unevenness of the edge of the board 20, resulting in jumping during edge banding; the first heating roller 7 is for preliminary heating to solve the jumping problem during the pressing of the edge banding strip caused by the internal stress in the edge banding strip, heating the edge banding strip to make the plastic softer and easier to fit the edge of the board 20; in order to achieve a better feeding effect, several conveying wheels 8 are evenly arranged between the first fixing plate 2 and the second fixing plate 3, which can easily push the board 20 for feeding; several auxiliary wheels 11 are evenly arranged between the third fixing plate 9 and the fourth fixing plate 10, which can better assist in pressing and feeding the board 20; patterns are provided on the surfaces of the first pressing roller 17 and the second pressing roller 18 to better increase the friction with the plastic edge banding strip, prevent slipping during pressing, resulting in the edge banding strip not being tightly pressed against the edge and affecting the edge banding effect. By turning the nut 14, the pressure value of the pressing mechanism 12 can be conveniently adjusted to adapt to boards 20 of different thicknesses and materials, improving the adaptability of the equipment. The patterns on the surfaces of the first pressing roller 17 and the second pressing roller 18 not only increase the friction but also improve the stability of the edge banding strip, keeping the edge banding strip in close contact with the edge of the board 20 during the edge banding process and reducing the problem of uneven glue pressing caused by sliding.

[0027] Working principle: First, the staff evenly apply glue to the edge of the board 20 to be bonded, place the plastic edge banding strip roll on the tape shaft 5, take one end and send it into the first heating roller 7, turn on the heating, the first heating roller 7 heats the edge banding strip, place a board 20 on the conveying wheel 8, and place one end of the edge banding strip at the edge of the board 20, push the board 20 to the second heating roller 16. By turning the nut 14, the pressure value of the pressing mechanism 12 can be adjusted. By turning the nut 14, the pressure value of the pressing mechanism 12 can be conveniently adjusted to adapt to boards 20 of different thicknesses and materials, improving the adaptability of the equipment. The patterns on the surfaces of the first pressing roller 17 and the second pressing roller 18 not only increase the friction but also improve the stability of the edge banding strip, keeping the edge banding strip in close contact with the edge of the board 20 during the edge banding process and reducing the problem of uneven glue pressing caused by sliding. The settings of the first heating roller 7 and the second heating roller 16 can heat the edge banding strip to make the plastic softer and easier to fit the edge of the board 20, and at the same time solve the jumping problem caused by the internal stress of the edge banding strip.

[0028] After adjusting to the appropriate area, push the board 20 for edge banding. The pressing mechanism 12 presses the board 20 through the spring 19. The other edge of the board 20 is in contact with the auxiliary wheel 11. At this time, just push the board 20 forward, and the edge banding strip moves forward synchronously with the board 20. The second heating roller 16 heats the edge banding strip again, and at the same time heats the glue on the edge of the board 20, so that the sealing strip can be better bonded to the board 20, improving the performance of the glue. The first pressing roller 17 initially presses the edge banding strip, and the second pressing roller 18 presses the sealing strip again, which can prevent jumping after pressing and affecting the pressing effect. After all the board 20 is pushed out, cut the excess edge banding strip, and the edge banding of the board 20 can be completed.
