Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment, specifically a film cutting machine that neatly adheres the edges of the sheet metal to the adhesive film. Background Technology

[0002] In many panel processing processes, such as furniture manufacturing and decorative material manufacturing, it is often necessary to coat the panels with a film to improve their appearance and durability. After coating, the panels need to be cut to remove excess film. However, current film cutting methods rely heavily on manual operation, which is inefficient and results in uneven and discontinuous cuts, especially for large panels such as door panels, where high-speed and high-quality cutting is difficult to achieve.

[0003] In addition, manual film cutting not only wastes manpower and resources, but is also untimely, which has a significant impact on production efficiency and product quality, resulting in higher production costs. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-10A film-cutting machine that neatly adheres the edges of the sheet material to the adhesive film includes a first guide frame 1, a positioning component, front and rear edge film-cutting components 8, left and right edge film-cutting components 9, and a second guide frame 2. First side guide plates 3 are fixedly connected to the upper two sides of the first guide frame 1, and several guide rollers 4 are rotatably connected between the first side guide plates 3 for conveying the sheet material. A positioning component is fixedly connected inside the first guide frame 1 for adjusting and positioning the sheet material. Front and rear edge film-cutting components 8 are fixedly connected to the upper end of the first side guide plates 3 for cutting off excess adhesive film from the front and rear edges of the sheet material. Left and right edge film-cutting components 9 are fixedly connected to one end of the first guide frame 1 for cutting off excess adhesive film from the left and right sides of the sheet material. The second guide frame is fixedly connected to the other end of the left and right edge film-cutting components 9. 2. The upper ends of the second guide frame 2 are fixedly connected to the second side guide plates 5. Several discharge rollers 6 are rotatably connected between the second side guide plates 5. The discharge rollers 6 are used to discharge the board. In use, the board is placed on the guide rollers 4 and conveyed by the guide rollers 4. During the conveying process, the position of the board is positioned by the positioning component. After that, the front end of the board stops after reaching the front and rear edge cutting components 8. The adhesive film on the front edge of the board is cut off by the front and rear edge cutting components 8. Then the board continues to be conveyed by the guide rollers 4 to the left and right edge cutting components 9. When the board passes the left and right edge cutting components 9, the adhesive film on the left and right edges of the board is cut off. When the rear edge of the board passes the front and rear edge cutting components 8, the adhesive film on the rear edge of the board can be cut off. Finally, the board is output outward by the discharge rollers 6.

[0026] In one embodiment, a plurality of pressing components 7 are fixedly connected to the first side guide plate 3 and the second side guide plate 5, respectively. The pressing components 7 are used to press the sheet metal tightly onto the guide roller 4 or the discharge roller 6.

The end of the push rod of the telescopic cylinder 102 is fixedly connected to the sliding block 103. In use, the board is placed on the guide roller 4. After the board is conveyed to the positioning component along the guide roller 4, the transmission of the guide roller 4 is stopped. After the positioning component positions the board, the telescopic cylinder 102 drives the sliding block 103 to move downward. The sliding block 103 drives the pressure roller 105 to contact the board downward. Under the pressure of the pressure roller 105, the friction between the board and the guide roller 4 increases, which facilitates the precise transmission of the guide roller 4, thereby facilitating the front and rear edge cutting film assembly 8 to cut the front and rear films of the board.

[0027] In one embodiment, the positioning component includes a drive block 201, a bidirectional lead screw 202, and a guide rod 203.

A third coupling 313 and a fourth coupling 314 are slidably connected to the linkage shaft 309. A limit strip is fixedly connected to the linkage shaft 309. Limit grooves are respectively provided on the third coupling 313 and the fourth coupling 314, and the limit strip is slidably connected within the limit grooves. The third coupling 313 meshes with the first coupling 311, and the fourth coupling 314 meshes with the second coupling 312. A U-shaped coupling 310 is rotatably connected to the third coupling 313 and the fourth coupling 314 on both sides. A transmission block 320 is fixedly connected to the U-shaped end.

One end of the first threaded rod 324 is connected to a first motor 321, which is fixedly connected to the lower end of the crossbeam plate 317. The first threaded rod 324 is threaded through the transmission block 320. A first worm gear 305 is fixedly connected to the middle of the linkage shaft 309. A drive shaft 326 is connected through the linkage housing 304. A first worm 306 is fixedly connected to the drive shaft 326 located inside the linkage housing 304, and the first worm 306 meshes with the first worm gear 305.One end of the drive shaft 326 is connected to the second motor 322, which is fixedly connected inside the first guide frame 1. The other end of the drive shaft 326 passes through the left and right side cutting film assemblies 9 and is rotatably connected inside the second guide frame 2. A second worm gear 308 is fixedly connected to the drive shaft 326 inside the second guide frame 2. The second worm gear 308 meshes with a second worm wheel 307. The second worm wheel 307 is fixedly connected to a third transmission shaft 325, which is rotatably connected inside the second guide frame 2. One end of the third transmission shaft 325 passes through the second guide frame 2 and is fixedly connected to a sixth gear 323. The second motor 322 engages with the third gear 303. In operation, the second motor 322 drives the drive shaft 326 to rotate. The drive shaft 326 drives the first worm 306 and the second worm 308 to rotate relative to each other. The first worm 306 and the second worm 308 respectively drive the first worm wheel 305 and the second worm wheel 307 to rotate relative to each other. The second worm wheel 307 drives the third transmission shaft 325 to rotate. The third transmission shaft 325 drives the sixth gear 323 to rotate. The sixth gear 323 drives the third gear 303 to rotate via a chain. The third gear 303 drives the discharge roller 6 to rotate, thereby driving the sheet material outward through the discharge roller 6.

[0029] Additionally, the first worm gear 305 drives the linkage shaft 309 to rotate. The two ends of the linkage shaft 309 are rotatably connected to one end of the first transmission shaft 315 and the second transmission shaft 316, respectively. The linkage shaft 309 drives the third coupling 313 and the fourth coupling 314 to rotate relative to each other via a limiting strip and a limiting groove. However, the third coupling 313 and the fourth coupling 314 slide relative to each other along the linkage shaft 309 via a U-shaped coupling 310. When the guide roller 4 needs to drive the plate, the first motor 321 drives the first threaded rod 324 to rotate. The first threaded rod 324 drives the transmission block 320 to move relative to each other along the sliding groove hole. 0 drives the U-shaped coupling 310 and the third coupling 313 and the fourth coupling 314 to move relative to each other, so that the third coupling 313 meshes with the first coupling 311. At this time, the linkage shaft 309 drives the third coupling 313 to rotate, the third coupling 313 drives the first coupling 311 to rotate relative to each other, the first coupling 311 drives the first transmission shaft 315 to rotate, the first transmission shaft 315 drives the fourth gear 318 to rotate, the fourth gear 318 drives the first gear 301 to rotate through the chain, and the first gear 301 drives the guide roller 4 to rotate relative to each other, thereby transmitting relative transmission to the plate through the guide roller 4.

[0030] When the plate needs to be positioned using the positioning assembly, the first motor 321 drives the first threaded rod 324 to rotate in the opposite direction. The first threaded rod 324 drives the second coupling 312 to move in the same direction. At this time, the third coupling 313 separates from the first coupling 311, while the fourth coupling 314 moves towards the second coupling 312 until the fourth coupling 314 meshes with the second coupling 312. Then, the linkage shaft 309 drives the fourth coupling 314 to rotate, which in turn drives the second coupling 312 to rotate. The second coupling 312 drives the second transmission shaft 316 to rotate, which in turn drives the fifth gear 319 to rotate. The fifth gear 319 drives the second gear 302 to rotate via a chain, which in turn drives the bidirectional lead screw 202 to rotate. The bidirectional lead screw 202 drives the drive block 201, the movable plate 204, and the positioning block 205 to move relative to each other, thereby positioning the plate using the positioning block 205.

In use, when the front or rear end of the board reaches the position of the front and rear edge cutting assembly 8, the fourth motor 510 drives the second threaded rod 511 to rotate. The second threaded rod 511 drives the sliding block 505 to move relative to each other. During this process, the lifting cylinder 506 drives the lifting plate 507 to move downward. At the same time, the fourth motor 510 drives the cutting wheel 509 to rotate. The cutting wheel 509 removes the adhesive film from the front and rear edges of the board. After the adhesive film is removed, the lifting cylinder 506 drives the lifting plate 507 to move upward, so that the cutting wheel 509 leaves the board.

[0033] The working principle of this invention is as follows: In use, the sheet material for which the adhesive film needs to be cut off at the edge is placed on the guide roller 4. Then, the third coupling 313 engages with the first coupling 311, causing the guide roller 4 to move the sheet material. When the sheet material reaches the area where the positioning component is located, the third coupling 313 disengages from the first coupling 311, and the fourth coupling 314 engages with the second coupling 312. During the engagement and disengagement of the third coupling 313 with the first coupling 311 and the fourth coupling 314 with the second coupling 312, the second motor 322 will stop running to facilitate the engagement and disengagement of the third coupling 313 with the first coupling 312. 311. The fourth coupling 314 engages and disengages with the second coupling 312. After the fourth coupling 314 and the second coupling 312 mesh, the plate is positioned by the positioning component. After the plate is positioned relative to the positioning component, the plate is rolled by the pressing component 7 to increase the friction between the guide roller 4 and the plate, thereby facilitating the accurate conveying of the plate. Then, the front and rear edges of the plate are cut off by the front and rear edge cutting components 8. In addition, when the plate passes through the left and right edge cutting components 9, the excess adhesive film on both sides of the plate is cut off by the cutting blade 409. Finally, the plate is discharged by the discharge roller 6.

[0034] In this invention, the first coupling 311, the second coupling 312, the third coupling 313, and the fourth coupling 314 are all crown gears. Their main structure includes a connecting tube, with several gear teeth fixedly connected to the end of the connecting tube. The ends of the gear teeth have a tapered structure. During the engagement and disengagement process, the third coupling 313 and the first coupling 311, and the fourth coupling 314 and the second coupling 312, can interlock and mesh with each other through the tapered structure of the gear teeth.
