Description

Technical Field

[0001] This utility model belongs to the technical field of anti-rolling devices, and particularly relates to an anti-rolling device for straight-blade cutting of thin films. Background Technology

[0002] In film slitting, straight blade slitting is a common process, but the edges of the film are prone to curling due to thermal or mechanical stress after slitting, which affects subsequent use. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by proposing the following technical solution:

[0004] An anti-rolling device for straight-blade slitting of film includes a base plate, a motor mounted on the bottom end of the base plate, a gear connected to the output end of the motor, two sets of symmetrically distributed rack plates meshing with the outer wall of the gear, and a side plate fixedly connected to the outer side of the rack plates by a connecting block.

[0005] A lifting mechanism is provided on the side plate. The lifting mechanism includes a lead screw, a threaded block, a servo motor, and a limiting component. The top end of the lead screw is connected to the output end of the servo motor. The threaded block is threadedly connected to the lead screw and is limited to sliding by the limiting component. The threaded block is fixedly connected to the top plate.

[0006] The top plate is connected to the pressure plate via a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a plug-in plate, a plug-in rod, a limiting rod, and a return spring. The top of the plug-in plate is inserted into the top plate and limited by the plug-in rod. The limiting rod is slidably connected to the top plate and engages with the plug-in rod. The return spring is used to reset the limiting rod.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes a limiting slider and a limiting slide rail. The limiting slide rail is formed in a first slot on the inner side of the side plate. The limiting slider is fixed to the outer wall of the threaded block and slidably connected to the limiting slide rail.

[0008] As a preferred embodiment of the above technical solution, the bottom end of the base plate is symmetrically provided with slide rails, and a first slider is slidably connected inside the slide rails. The first slider is fixedly connected to the side plate through a connecting plate.

[0009] As a preferred embodiment of the above technical solution, the disassembly and assembly mechanism further includes a slide rod, a second slider, and a pull plate. The slide rod is fixed in the second slot of the top plate, the second slider is slidably connected to the slide rod and fixed to the pull plate, and the outer wall of the pull plate is provided with a pull ring.

[0010] As a preferred embodiment of the above technical solution, the reset spring is sleeved on the outer wall of the slide bar, with one end connected to the second slider and the other end fixed to the inner wall of the second slot.

[0011] The beneficial effects of this utility model are as follows:

[0012] In this application, the distance between the two side plates can be adjusted synchronously through the meshing transmission of the motor-driven gear and the rack plate, which can quickly adapt to the film slitting requirements of different widths. Combined with the sliding cooperation between the slide rail at the bottom of the base plate and the first slider, the side plates can be moved smoothly, avoiding deviation and significantly improving the adjustment accuracy and efficiency.

[0013] The lifting mechanism using a lead screw and threaded block, combined with the guiding action of the limit slider and slide rail, allows the pressure plate to press down vertically on the edge of the film, resulting in uniform pressure distribution and precise adjustment. The surface of the pressure plate is equipped with anti-slip textures or an elastic buffer layer, which not only prevents the film from being scratched but also enhances the pressing effect and effectively suppresses curling deformation after slitting.

[0014] By combining the plug plate, plug rod and limit rod, and the automatic reset function of the reset spring, the pressure plate can be quickly disassembled and replaced. During operation, maintenance can be completed simply by pulling the pull ring, which greatly reduces downtime and improves production efficiency. It is especially suitable for continuous processing of multi-specification films. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the anti-rolling edge device for straight-blade slitting of film includes a base plate 1; a motor 3 is installed at the bottom end of the base plate 1, and a gear 2 is connected to the output end of the motor 3. Two sets of rack plates 4 are meshed on the outer wall of the gear 2. Connecting blocks 5 are installed on the outer side of each rack plate 4. The outer side of the connecting blocks 5 is connected to the side plate 9. A top plate 16 is connected to the side plate 9 through a lifting mechanism. A pressure plate 18 is connected to the top plate 16 through a disassembly and assembly mechanism. The film to be slit is flattened and placed on the base plate 1. Through the cooperation of the lifting mechanism and the meshing movement of the gear 2 and rack plates 4, the pressure plate 18 is driven to flatten and compact the edge of the film, thereby completing the anti-rolling edge operation. The pressure plate 18 is made of silicone material and has anti-slip texture on the surface to enhance friction.

[0022] like Figure 1 As shown, the lifting mechanism includes a threaded block 12 installed on the side wall of the top plate 16. The threaded block 12 is threadedly connected to the outer wall of the lead screw 11. The top end of the lead screw 11 is connected to the bottom output end of the servo motor 13. The servo motor 13 is installed in the first slot 10, which is located on the inner side wall of the side plate 9. A limiting slider 14 is connected to the outer wall of the threaded block 12, and the limiting slider 14 slides within a limiting slide rail 15, which is located within the first slot 10. After the servo motor 13 starts, it drives the lead screw 11 to rotate. The threaded block 12 moves up and down along the lead screw 11 and slides within the limiting slide rail 15 via the limiting slider 14, ensuring that the top plate 16 moves vertically. The top plate 16 drives the pressure plate 18 to press down onto the surface of the bottom plate 1, applying pressure to the edge of the film.

[0023] like Figure 2 As shown, a slide rail 8 is symmetrically provided at the center of the bottom end of the base plate 1, and a first slider 7 is slidably connected inside the slide rail 8. The first slider 7 is installed at the bottom end of the connecting plate 6, and the outer side of the connecting plate 6 is connected to the side plate 9. The motor 3 drives the gear 2 to rotate, which drives the rack plate 4 to move laterally along the slide rail 8 at the bottom of the base plate 1. Through the cooperation of the connecting plate 6 and the first slider 7, the distance between the two side plates 9 is adjusted to adapt to films of different widths.

[0024] like Figure 1 and Figure 3As shown: The disassembly and assembly mechanism includes a plug-in plate 17 mounted on the pressure plate 18, with the top end of the plug-in plate 17 inserted into the top plate 16. A plug-in rod 19 is symmetrically mounted on the top end of each plug-in plate 17, and the top end of each plug-in rod 19 penetrates the outer wall of the top plate 16. A limit rod 20 is inserted into the outer side of each plug-in rod 19, and the limit rod 20 is connected to a pull plate 21. The bottom end of each pull plate 21 is connected to a second slider 23. The second slider 23 slides symmetrically on the outer wall of a slide rod 24. Installed within the second slot 25, which is located at the center of the top of the top plate 16, the second slider 23 has a return spring 26 connected to its outer side wall, with the outer side of the return spring 26 connected to the second slot 25. The middle part of the return spring 26 surrounds the outer wall of the slide rod 24. The outer wall of the pull plate 21 is connected to a pull ring 22. Pulling the pull ring 22 causes the pull plate 21 to move the limiting rod 20 away from the plug-in rod 19, pulling down the pressure plate 18, and separating the plug-in plate 17 from the top plate 16. During installation, the plug-in plate 17 is inserted into the top plate 16, the pull ring 22 is released, and the return spring 26 pushes the limiting rod 20 into the plug-in rod 19 to complete the fixation.

[0025] Working principle

[0026] Film positioning and pressing: The film is laid flat on the base plate 1. The motor 3 drives the gear 2 to mesh with the rack plate 4, and the distance between the two side plates 9 is adjusted to the width of the film. The servo motor 13 drives the lead screw 11 to rotate, causing the top plate 16 to press down. The pressure plate 18 applies uniform pressure to the edge of the film to eliminate edge curling after slitting.

[0027] Lifting and limiting: The threaded engagement between the lead screw 11 and the threaded block 12 enables lifting and lowering. The limiting slider 14 and the slide rail 15 prevent the top plate 16 from shifting, ensuring that the pressure plate 18 moves vertically.

[0028] Quick disassembly and maintenance: The connection status of the limit rod 20 and the insertion rod 19 is controlled by the pull ring 22, so that the pressure plate 18 can be quickly replaced to adapt to the processing needs of films of different thicknesses or materials.

[0029] Reset and stability: The reset spring 26 automatically resets the limit rod 20 after disassembly, and the slide bar 24 and the second slider 23 ensure the linear movement of the pull plate 21, improving operational reliability.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
