Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, and in particular to a punching device for plastic film processing. Background Technology

[0002] Currently, most common plastic film punching devices use a cylinder-driven punching method, which requires high precision in mold fitting. By setting an electric heating tube in the lower mold to heat and soften the plastic film before punching, the edges of the punched holes are made neater and smoother. However, this device requires an additional cooling mechanism to prevent the plastic film from sticking to the mold. Traditional devices often use gravity-feeding or exhaust pipes to remove the film, which can easily lead to waste accumulation. For irregularly shaped or large holes, traditional punching devices have difficulty achieving a flat opening and require custom-made special tools or the use of another machine.

[0003] In summary, we propose a punching device for plastic film processing. When the fan is started, the air force blows the plastic film up, the gripper clamps the plastic film, and then sends it into the adjacent clamping strip, so that the clamping strip holds the two sides of the plastic film. Then, the motor uniformly winds the plastic film into the middle of the take-up roller, thus realizing continuous and efficient plastic film processing while punching. A storage box and drawer are installed at the bottom of the plastic film at the top of the worktable to collect the punched plastic film in the hole opened in the middle of the worktable and then into the storage box, thereby improving production efficiency.

[0026] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0027] Please refer to Figures 1-6 This utility model proposes a punching device for processing plastic film, including a worktable 1, a support 2, a clamping assembly, and a punching assembly. The worktable 1, the support 2, and the clamping assembly are all installed on the top of the worktable 1, and the punching assembly is fixedly connected to the middle of the bottom end of the crossbeam of the support 2.

[0028] A set of support plates 3 are fixedly installed on both sides of the top center of the workbench 1. A take-up roller 4 is movably installed in the middle of the set of support plates 3. The take-up roller 4 is divided into a discharge roller and a take-up roller. The discharge roller is located at the front end of the support 2, and the take-up roller is located at the rear end of the support 2. Fans 5 are movably installed in the middle of both sides of the support plates 3. The fans 5 are located between the take-up roller 4 and the gripper 7. The base of the fans 5 is triangular, and the fans 5 are arranged horizontally.

[0029] The clamping assembly includes a worktable 1, with a set of support plates 3 fixedly installed on both the front and rear sides of the worktable 1. A take-up roller 4 is movably installed in the middle of the support plate 3. A gripper 7 is fixedly installed at the top of the middle of the support plate 3. A clamping bar 8 is movably installed at the adjacent rear end of the gripper 7. The clamping bar 8 is evenly installed on both sides of the plastic film 13. The gripper 7 clamps the plastic film 13 by applying clamping force, thereby fixing the position of the plastic film 13. The clamping force can be generated by pneumatic, hydraulic or electric means. When the input force is applied to the transmission component of the gripper 7, the transmission component converts the input force into the clamping force of the gripper 7 clamping head. This clamping force is usually applied to the object being clamped by the clamping surface on the clamping head. When the gripper 7 clamps the plastic film 13, it is transported into the clamping bar 8, so that the plastic film 13 can be smoothly and smoothly wound into the roller shaft of the take-up roller 4.

[0030] A motor 9 is mounted on the outer side of a set of support plates 3 fixedly installed on one side of the top of the workbench 1. The output shaft of the motor 9 is fixedly connected to a driving gear 10 and a driven gear 11. The gear consists of two parts: a small driving gear 10 is fixedly installed at the front end of the take-up roller 4, and a large driven gear 11 is fixedly installed on one side of the take-up roller 4. Both gears are fixedly connected to the top of a rack 12. When the motor 9 drives the driving gear 10 and the driven gear 11 to rotate, the driving gear 10 and the driven gear 11 are meshed with the rack 12. When the driving gear 10 and the driven gear 11 rotate, they are affected by the resistance of the rack 12. The motor 9 rotates in a circular motion. The motion of the rotating shaft pulls the plastic film 13 inside the take-up roller 4, which in turn drives the drive gear 10, driven gear 11, and rack 12 to rotate as a whole. This pulls one end of the plastic film 13 inside the take-up roller 4. The take-up roller 4 is horizontally mounted at the end away from the take-up roller 4. A set of support plates 3 are fixedly connected to the opposite side of the take-up roller 4. A motor 9 is also installed on the outside of the set of support plates 3. The output shaft of the motor 9 is fixedly connected to the drive gear 10 and driven gear 11. The take-up roller 4 is fixedly installed in the middle of the set of support plates 3. After the plastic film 13 is clamped and pulled into the inside of the clamping strip 8 by the gripper 7, it is wound into the middle of the take-up roller 4, thus completing the take-up of the plastic film 13.

[0031] The punching assembly includes two hydraulic rods 14 fixedly installed in the middle of the crossbeam of the support 2. A cross brace 15 in the shape of an inverted U is fixedly connected to the bottom end of the hydraulic rods 14. A shaft wheel 16 is fixedly installed on the inner walls of both sides of the inverted U-shaped cross brace 15. A movable turntable 17 is movably installed in the middle of the shaft wheel 16. Multiple punching heads 18 are movably connected around the movable turntable 17. Support rods 19 are fixedly connected to both sides of the punching head 18. The two ends of the support rods 19 are fixedly connected to the middle of the inner wall of the support 2. The support rods 19 pass through the inverted U-shaped cross brace 15 and the shaft wheel 16. The punching head 18 is driven to move up and down by the hydraulic rods 14. When the punching head 18 moves down, it punches the plastic film 13 fixed at the top of the workbench 1.

[0032] A storage box 20 is fixedly installed at the bottom center of the workbench 1. A drawer 6 is movably installed inside the storage box 20. The drawer 6 is a pull-out type. The drawer 6 is pulled out and pushed in by sliding on a fixed track. When a pulling force is applied, the drawer 6 slides outward along the track. When a pushing force is applied, the drawer 6 slides inward and returns to its original position. Multiple elongated holes are opened on both sides of the storage box 20.

[0033] In summary, the entire punching and winding process is driven by the motor 9 and works in coordination with the fan 5, gripper 7, clamping strip 8, and punching head 18. When the fan 5 starts, the air force blows the plastic film 13 up, the gripper 7 clamps the plastic film 13, and then sends it into the adjacent clamping strip 8, so that the clamping strip 8 clamps the two sides of the plastic film 13. Then, the motor 9 winds the plastic film 13 into the middle of the winding roller 4 at a uniform speed, thus realizing continuous and efficient punching of the plastic film 13 during processing. A storage box 20 and a drawer 6 are installed at the bottom of the plastic film 13 at the top of the worktable 1 to collect the punched plastic film 13 in the hole opened in the middle of the worktable 1 and then into the storage box 20. This improves the service life and stability of the equipment, reduces manual intervention, and increases production efficiency.

[0034] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
