Description

Technical Field

[0001] This utility model belongs to the field of PVC film cutting and punching technology, and specifically relates to a PVC film cutting and punching device. Background Technology

[0002] PVC film is one of the most common materials used in the market. It has a wide range of functions. Cutting and punching PVC film is widely used in the field of PVC packaging. Due to the special surface treatment of PVC film, the surface of PVC film has good self-cleaning properties. Rainwater will gather into water droplets on its surface and run off, so that the surface of the film is naturally cleaned, thus demonstrating good sealing effect. Therefore, it is necessary to punch holes in the film to prevent the possibility of mold growth inside due to temperature difference.

[0003] In the current technology of PVC film cutting and punching devices, a cylinder is generally used to push the punching head through the film surface and press it into the punching mold. However, the position of the punching head in the punching mechanism is generally fixed, and it can only punch holes in fixed positions. It cannot punch holes in other positions according to needs, which is not very practical. In addition, the current PVC film punching mechanism generally does not have a flattening mechanism, which makes the hole position on the film surface easy to shift after cutting.

[0004] Therefore, a PVC film cutting and punching device is needed to meet people's needs. Utility Model Content

[0005] In view of some or all of the problems existing in the prior art, the present invention provides a PVC film cutting and punching device, which can realize a perforated plate structure that improves the fixing effect between the perforated plate and the fixing block.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PVC film cutting and punching device includes two support plates. A lead screw is rotatably mounted on one side of each support plate. A motor is mounted on the front end of the lead screw, which passes through the rear surface of the corresponding support plate. A movable stage is threaded onto the support plate wall. A through hole is formed on the front surface of the movable stage. A limit rod is slidably mounted on the inner wall of the through hole. The front and rear ends of the limit rod are fixed to the opposite sides of the two support plates, respectively. A fixed plate is mounted on the upper surface of the movable stage. A cylinder is mounted on the upper surface of the fixed plate. A punching assembly is located at the output end of the cylinder. A flattening assembly is located below the inner wall of the fixed plate. A feeding roller is rotatably mounted on the left side of the opposite sides of the two support plates. A feeding roller is rotatably mounted on the right side of the opposite sides of the two support plates. A pressing device and a pressing plate are located on the right side of the feeding roller. The front and rear sides of the pressing device and the pressing plate are fixed to the opposite sides of the two support plates, respectively.

[0008] Preferably, the punching assembly includes a U-shaped block, the upper surface of which is fixed to the output end of the cylinder, and a punching head is threadedly installed on the inner wall of the U-shaped block by a first bolt. A mold plate is provided directly below the punching head.

[0009] Preferably, the flattening assembly includes a connecting plate, the inner wall of which is fixed to the outer wall of the cylinder output end, and limit cylinders are installed on both the front and rear surfaces of the connecting plate. Limit springs are installed on the upper part of the inner walls of the two limit cylinders, and pressure blocks are installed on the lower ends of the two limit springs.

[0010] Preferably, the outer walls of the two pressure blocks are slidably mounted on the inner walls of the corresponding limiting cylinders.

[0011] Preferably, a sliding plate is slidably mounted on the outer wall of the mold plate, and an adjustment port is provided on the left side surface of the sliding plate.

[0012] Preferably, a threaded groove is provided on the left side of the outer wall of the mold plate, and a locking bolt is threadedly installed on the inner wall of the threaded groove. The locking bolt is located inside the adjustment port.

[0013] Preferably, a receiving plate is installed on the right side of the opposite surface of the two support plates. The inner wall of the receiving plate is rounded.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a lead screw, moving table, through hole, limit rod, and motor, the machine can move the moving table and drilling head along the rod wall of the lead screw and limit rod to a specified position before drilling, according to the drilling position requirements. This improves the practicality of the machine. At the same time, the pressing block in the flattening component flattens the drilling position before drilling, thus preventing the hole position on the film surface from easily shifting after cutting.

[0016] 2. By rotating the locking bolt and releasing the mold plate connected to the thread, the locking bolt and the mold plate are then pushed to move along the inner wall of the adjustment port to move the mold plate to the designated position. The mold plate is then fixed inside the sliding plate by the locking bolt, which allows for arbitrary adjustment of the punching position. This enables the equipment to punch holes for films of different widths, thus adapting to more market demands. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4As shown, this embodiment provides a PVC film cutting and punching device, including two support plates 1. A lead screw 2 is rotatably mounted on one side of each support plate 1. The front end of the lead screw 2 passes through the rear surface of the corresponding support plate 1 and is fitted with a motor 19. A movable stage 3 is threaded onto the wall of the support plate 1. A through hole 4 is formed on the front surface of the movable stage 3. A limit rod 5 is slidably mounted on the inner wall of the through hole 4. The front and rear ends of the limit rod 5 are fixed to the opposite sides of the two support plates 1, respectively. A fixed plate 6 is mounted on the upper surface of the movable stage 3. A cylinder 7 is mounted on the upper surface of the fixed plate 6. A punching assembly is provided at the output end of the cylinder 7. A flattening assembly is provided below the inner wall of the fixed plate 6. A feeding roller 15 is rotatably mounted on the left side of the opposite sides of the two support plates 1. A feeding roller 16 is rotatably mounted on the right side of one side surface. A pressing device 17 and a pressing plate 18 are set on the right side of the feeding roller 16. The front and rear sides of the pressing device 17 and the pressing plate 18 are respectively fixed to the opposite side surfaces of the two support plates 1. The punching assembly includes a U-shaped block 8. The upper surface of the U-shaped block 8 is fixed to the output end of the cylinder 7. A punching head 9 is threadedly installed on the inner wall of the U-shaped block 8 through a first bolt. A mold plate 14 is set directly below the punching head 9. By controlling the motor 19, the moving table 3 and the punching head 9 are moved along the rod wall of the lead screw 2 and the limit rod 5 to a designated position to punch holes, thereby improving the practicality of the equipment. At the same time, the punching position is flattened by the pressing block 13 in the flattening assembly before punching, thereby preventing the problem that the hole position on the film surface is prone to displacement after cutting.

[0025] The flattening assembly includes a connecting plate 10. The inner wall of the connecting plate 10 is fixed to the outer wall of the output end of the cylinder 7. Limiting cylinders 11 are installed on both the front and rear surfaces of the connecting plate 10. Limiting springs 12 are installed on the upper part of the inner wall of the two limiting cylinders 11. Pressure blocks 13 are installed on the lower end of the two limiting springs 12. The outer walls of the two pressure blocks 13 are slidably installed on the inner walls of the corresponding limiting cylinders 11. The pressure blocks 13 in the flattening assembly flatten the punching position before punching, thereby preventing the position of the membrane from shifting during the punching process.

[0026] Furthermore, such as Figure 3 and 4As shown, a sliding plate 20 is slidably mounted on the outer wall of the mold plate 14. An adjustment port 21 is provided on the left side surface of the sliding plate 20. A threaded groove is provided on the left side of the outer wall of the mold plate 14. A locking bolt 22 is threadedly installed on the inner wall of the threaded groove. The locking bolt 22 is located inside the adjustment port 21. By rotating the locking bolt 22 and releasing the mold plate 14 which is threadedly connected, the locking bolt 22 and the mold plate 14 are pushed to move along the inner wall of the adjustment port 21, moving the mold plate 14 to the designated position. Then, the locking bolt 22 is used to fix the mold plate 14 inside the sliding plate 20, which facilitates arbitrary adjustment of the punching position. This allows the equipment to punch holes for films of different widths, thereby adapting to more market demands.

[0027] Furthermore, such as Figure 1 As shown, a receiving plate 23 is installed on the right side of the opposite surface of the two support plates 1. The inner wall of the receiving plate 23 is rounded to prevent damage to the cut film after it slips onto the receiving plate 23.

[0028] Working Principle: This invention, when punching holes in PVC film, first flattens the film surface before punching, then punches holes using the punching head 9. It can also punch holes at designated locations as needed, making operation convenient. During use, the motor 19 drives the lead screw 2 and the moving platform 3 to rotate together. Simultaneously, the moving platform 3 is limited by the limiting rod 5, causing it to move along the walls of the limiting rod 5 and the lead screw 2. This movement also drives the cylinder 7 and the punching head 9. After the punching head 9 is moved to the designated position, the control... The cylinder 7 pushes the punch head 9 downward to perform the punching operation. While moving, the pressure block 13 first contacts the surface of the film and pushes the limit spring 12 to retract along the inner wall of the limit cylinder 11. At the same time, the film around the punching position is flattened. Then, the punch head 9 is pressed into the mold plate 14 to punch the hole, thus preventing the problem of different positions after punching. At the same time, the U-shaped block 8 and the punch head 9 are connected by the first bolt, which makes it easy to replace when punching different shaped holes, thereby improving the versatility of the equipment.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
