Technical Field

[0001] The utility model relates to the field of packaging film processing, in particular to a trimming device for packaging film processing. Background Art

[0002] Packaging film is a thin film material widely used in the packaging of goods. It is primarily used to wrap products or pallets to increase cargo stability and protect them from damage during transportation and storage. Packaging film can be divided into several types, each with its own specific application scenarios and characteristics.

[0003] During the production process of packaging film, trimming refers to trimming the edges of the film to remove irregular or uneven parts, ensuring that the edges of the film are neat and smooth, thereby improving the quality and appearance of the product.

[0004] When some existing trimming devices are used, several adapter slots are usually opened on the top of the device. When the cutter needs to be adjusted, the mobile chassis carrying the cutter needs to be disassembled and then installed in the next adapter slot. However, this adjustment method is inconvenient and the operator needs to spend a lot of time manually adjusting the position of the cutter. The operation process is complicated and time-consuming.

[0005] Therefore, it is particularly necessary to propose a trimming device for packaging film processing. Utility Model Content

[0022] Embodiment: A trimming device for packaging film processing, such as Figures 1-4As shown, it includes a frame 1, a workbench 2, a motor 3, a pulley 31, a synchronous belt 32, a shaft seat 4, an air shaft 5, a guide rail 6, a slider 61, a slide 7, a screw 8, a knob 81, a guide rod 9, a bracket 10, an electric cutter 11 and a cylinder 12. The frame 1 serves as the main frame of the entire device, providing support and integrating other components. A workbench 2 is provided on the top of the frame 1 for installing and fixing other components, such as the shaft seat 4, the air shaft 5, etc. A motor 3 is provided at the bottom of the frame 1 to provide rotation The power drives the inflatable shaft 5 to rotate. A shaft seat 4 is provided on the top of the workbench 2. Pulleys 31 are provided on the shaft seat 4 and the output shaft of the motor 3. A synchronous belt 32 is provided between the two pulleys 31 for transmission, which transmits the power of the motor 3 to the inflatable shaft 5. The inflatable shaft 5 is provided on the right side of the shaft seat 4. When the inflatable shaft 5 is connected to the air source, its internal swelling structure is expanded. Two guide rails 6 are provided on both sides of the top of the workbench 2. The guide rails 6 on both sides correspond to the two ends of the inflatable shaft 5 respectively. There are also two guide rails 6 on each guide rail 6. There are two slides 61 and two slides 7. The two slides 7 are respectively arranged between the tops of the two slides 61 on the left and right sides. A screw rod 8 is rotatably arranged in the middle of the two slides 7. A knob 81 is arranged at one end of each screw rod 8. Guide rods 9 are arranged on both sides of the top of the two slides 7. The bracket 10 slides along the guide rod 9 to ensure that the cutter moves smoothly. Brackets 10 are slidably arranged on the top of the two slides 7 to support the electric cutter 11 to ensure that the cutter is stable during the cutting process. The lower part of the bracket 10 is slidably connected to the guide rod 9. The lower center of the bracket 10 is rotatably connected to the screw rod 8. The upper front side of the two brackets 10 is rotatably provided with an electric cutter 11 for cutting the edge of the packaging film to achieve trimming. Cylinders 12 are provided on both sides of the rear top of the workbench 2. The piston rod of the cylinder 12 pushes the slide 7 back and forth to adjust the position of the cutter relative to the coil. The piston rods of the two cylinders 12 are connected to the rear side of the corresponding slide 7. When the knob 81 is rotated, the screw rod 8 is driven to rotate, and the bracket 10 is driven by the screw rod 8 to move along the guide rod 9.

[0023] like Figures 1-4As shown, it also includes an electric slide rail 13, a matching plate 14, a mounting plate 15, a guide column 16, a matching block 17, a clamping ring 18 and a screw 19. Electric slide rails 13 are provided on both sides of the right side of the frame 1 for adjusting the position of the matching plate 14 to adjust the lateral position of the cutter. A matching plate 14 is provided between the electric slide rails 13 on both sides for supporting the mounting plate 15 to adjust the lateral position of the cutter. A mounting plate 15 is provided at the bottom of the matching plate 14 for supporting the guide column 16 to adjust the position of the clamping ring 18. Guide columns 16 are symmetrically provided on both sides of the mounting plate 15 for supporting The supporting mating block 17 is used to adjust the position of the clamping ring 18. The guiding column 16 is provided with a sliding mating block 17 on both sides for adjusting the position of the clamping ring 18 to fix the coil. The right side of the mating block 17 is provided with a clamping ring 18 for fixing the coil to prevent it from sliding during processing. The inside of the clamping ring 18 is provided with anti-slip teeth, and a screw 19 is threaded on one of the mating blocks 17 on the upper part for adjusting the position of the clamping ring 18 to fix the coil. When the screw 19 rotates, it drives the mating block 17 on one side to slide along the electric slide rail 13, thereby moving the clamping ring 18.

[0024] When in use, the operator first places the equipment in the desired position and ensures that the equipment is stable. Then, the packaging film coil to be processed is installed on the inflatable shaft 5. When the inflatable shaft 5 is connected to the air source, the swelling structure inside it will expand, so that the coil is fixed on the inflatable shaft 5 to prevent the coil from loosening during processing. The motor 3 is started, and the output shaft of the motor 3 drives the pulley 31 connected to it to rotate. Through the synchronous belt 32, this rotational power is transmitted to another pulley 31, which in turn drives the inflatable shaft 5 to rotate, so that the coil is unfolded as the inflatable shaft 5 rotates. By rotating the knob 81, the screw rod 8 is driven to rotate. The rotation of the screw rod 8 drives the bracket 10 connected to it to move along the guide rod 9, thereby adjusting the position of the electric cutter 11. In this way, the position of the cutter can be accurately adjusted to adapt to packaging films of different widths. When the electric cutter 11 is adjusted to the appropriate position, the operator can fix the position of the screw rod 8 by rotating the knob 81 to keep the cutter in this position unchanged. The electric cutter 11 starts working. Driven by the bracket 10, the electric cutter 11 moves linearly along the guide rod 9 to cut the edge of the packaging film. The piston rod of the cylinder 12 pushes the slide 7 back and forth to change the position of the cutter relative to the coil to achieve trimming operations at different positions. The slides 7 and the cutter on both sides move synchronously to ensure that the edges of both sides of the packaging film are evenly cut. The electric slide rail 13 drives the matching plate 14 to move horizontally to further adjust the position of the cutter relative to the coil. By rotating the screw 19, the matching block 17 can be driven to slide on the guide column 16 to adjust the position of the clamping ring 18. The anti-slip teeth on the inside of the clamping ring 18 can better fix the coil to prevent it from sliding during processing. When a section of the edge of the packaging film is successfully cut off, the above steps are repeated until the edge of the entire roll of packaging film is cleanly cut off. After all trimming operations are completed, the motor 3 and the electric cutter 11 are turned off, the air source is disconnected, and the trimmed packaging film is removed.

[0025] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
