Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically a novel slitting mechanism for plastic film processing. Background Technology

[0002] As is well known, existing plastic film slitting mechanisms are core equipment in the production processes of packaging, electronics, agriculture and other fields. Their function is to slit wide films into multiple rolls of narrow materials according to a preset width, and to ensure that the edges of the slit films are neat and the winding tension is uniform.

[0003] With the diversification of film materials (such as high-transparency PE film, composite aluminum foil film, etc.) and the increasing demand for precision processing, the shortcomings of traditional slitting equipment in terms of adjustment accuracy, cutting stability and automation are becoming increasingly prominent.

[0004] Specifically, traditional slitting machines mostly use manual adjustment of blade spacing or a single screw-driven cutting device, which results in time-consuming switching of slitting specifications (such as needing to stop the machine to disassemble when changing blades with different spacings), and the multi-blade synchronous adjustment accuracy is insufficient, making it difficult to meet the processing requirements of high-precision films. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a novel slitting mechanism for plastic film processing.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel slitting mechanism for processing plastic film, comprising a machine, a groove provided at the front end of the machine, an unwinding rod at the upper end of the groove, an adjusting mechanism provided at the center of the groove, multiple sets of hydraulic telescopic rods provided at the lower end of the adjusting mechanism, a cutting device provided on the bottom wall of the hydraulic telescopic rods, an auxiliary rod provided at the lower end of the groove, the auxiliary rod at the lower end of the cutting device, a winding device provided at the lower end of the front side wall of the machine, and a control panel provided on one side wall of the machine, the control panel being signal-connected to the aforementioned devices.

[0009] To achieve synchronized and precise displacement of multiple sets of hydraulic telescopic rods, this utility model improves upon the following: the adjustment mechanism includes a fixed box, positive and negative screws, sliders, and scissor rods. The fixed box is adapted to the groove, the positive and negative screws pass through the fixed box, the sliders are symmetrically arranged on the positive and negative screws, the positive thread on the positive and negative screws is threadedly connected to one of the sliders, and the negative thread is threadedly connected to the other slider. The sliders are fitted and slidably connected to the inner wall of the fixed box. Multiple sets of scissor rods with rotating shafts are provided at the lower end of the sliders. The bottom wall of the fixed box is provided with sliding holes, and the scissor rods are slidably connected to the sliding holes. A connecting plate is provided at the connection point of the bottom wall of the scissor rods, and the upper end of the hydraulic telescopic rod is connected to the bottom wall of the connecting plate.

[0010] To enable the direct-drive cutting blade to rotate at high speed, this utility model improves upon the following: the cutting device includes a protective frame, a rotating motor, and a cutting blade; the protective frame is connected to the bottom wall of the hydraulic telescopic rod; the rotating motor is located on one side of the protective frame; and the inner shaft of the cutting blade passes through the protective frame and is connected to the output end of the rotating motor.

[0011] To achieve precise digital control of the cutting width, this utility model has the following improvements: a control motor is provided on one side wall of the fixing box, and the positive and negative screws pass through the side wall of the fixing box and are connected to the output end of the control motor.

[0012] To enable real-time adjustment of the winding speed, this utility model improves upon the following: the winding device includes a support plate, an electric telescopic rod, a rotating column, and a limiting motor. The support plate is symmetrically arranged on both sides of the lower end of the front side wall of the machine. The rotating column is located on the inner side wall of the support plate. The electric telescopic rod is located at one end of the rotating column. The limiting motor is located on the outer side wall of one of the support plates. The rotating column passes through the support plate and is connected to the output end of the limiting motor. A clamping plate is provided at one end of the electric telescopic rod.

[0013] To reduce the defect rate caused by impurities being pressed into the cut during the slitting process, the present invention includes the following improvement: the surface of the auxiliary rod is covered with a layer of cleaning cotton.

[0014] To eliminate static electricity generated by friction between the film and the roller surface during winding, the present invention is improved by coating the surface of the winding device with an antistatic coating.

[0015] To reduce the risk of equipment damage, the present invention includes the following improvement: an emergency stop button is provided on the control panel.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a novel slitting mechanism for plastic film processing, which has the following beneficial effects:

[0018] This novel slitting mechanism for plastic film processing is equipped with an adjustment mechanism. As the screws rotate, and the slider moves in opposite directions within the fixed housing, the scissor lever can extend or retract. Utilizing the lever's leverage, the horizontal movement of the screws is converted into the vertical displacement of the hydraulic telescopic rod, enabling synchronized and precise adjustment of multiple cutting devices. This ensures consistent slitting width and is particularly suitable for slitting ultra-thin or high-precision films.

[0019] The cutting device uses a protective frame to enclose the rotating blade, effectively isolating the operator from high-speed moving parts and reducing safety hazards during the cutting process. Simultaneously, the rotating motor directly drives the cutting blade to rotate at high speed, ensuring a smooth and even cut, and reducing burrs and material tearing.

[0020] The control motor drives the forward and reverse screws to rotate, replacing the traditional manual adjustment method. The spacing of the cutting device can be automatically adjusted by preset parameters on the control panel, which significantly shortens the adjustment time, reduces manual intervention, and improves the efficiency of continuous production.

[0029] Please see Figure 1-4 A novel slitting mechanism for processing plastic film includes a machine 1. A groove is provided at the front end of the machine 1. A winding rod 9 is located at the upper end of the groove. An adjustment mechanism is located at the center of the groove. Multiple sets of hydraulic telescopic rods 16 are provided at the lower end of the adjustment mechanism. A cutting device is provided on the bottom wall of each hydraulic telescopic rod 16. An auxiliary rod 10 is located at the lower end of the groove, below the cutting device. A winding device is located at the lower end of the front side wall of the machine 1. A control panel 2 is located on one side wall of the machine 1 and is signal-connected to the aforementioned devices. The adjustment mechanism includes a fixed box 8, positive and negative screws 13, sliders 14, and a scissor bar 11. The fixed box 8 is adapted to the groove. The positive and negative screws 13 penetrate the fixed box 8. The sliders 14 are symmetrically arranged on the positive and negative screws 13, and the positive thread on the positive and negative screws 13 is threadedly connected to one of the sliders 14. The reverse thread is threaded to another slider 14. The slider 14 fits against and slides against the inner wall of the fixed box 8. The lower end of the slider 14 is provided with multiple sets of scissor rods 11 with rotating shafts 12. The bottom wall of the fixed box 8 is provided with sliding holes. The scissor rods 11 are slidably connected to the sliding holes. A connecting plate 15 is provided at the bottom wall connection of the scissor rods 11. The upper end of the hydraulic telescopic rod 16 is connected to the bottom wall of the connecting plate 15. The cutting device includes a protective frame 18, a rotating motor 17, and a cutting blade 19. The protective frame 18 is connected to the bottom wall of the hydraulic telescopic rod 16. The rotating motor 17 is on one side of the protective frame 18. The inner shaft of the cutting blade 19 passes through the protective frame 18 and is connected to the output end of the rotating motor 17. A control motor 20 is provided on one side wall of the fixed box 8. The positive and negative screws 13 pass through the side wall of the fixed box 8 and are connected to the output end of the control motor 20.

[0030] During use, the wide plastic film roll is installed on the unwinding rod 9. One end of the film is pulled out from the unwinding rod 9, passes through the adjustment mechanism area above the groove, goes down around the auxiliary rod 10, and finally extends to the winding device for fixation. Parameters such as slitting width and quantity are input through the control panel 2. After receiving the signal, the control system in the control panel 2 starts the control motor 20, which drives the positive and negative screws 13 to rotate. Since the threads on both sides of the positive and negative screws 13 are in opposite directions, the symmetrically arranged sliders 14 move synchronously in opposite directions along the screw axis within the fixed box 8. One slider 14 moves towards one end of the screw, and the other slider 14 moves in the opposite direction. The horizontal movement of the sliders 14 is controlled by multiple sets of shears. The fork lever 11 is converted to vertical displacement. When the distance between the sliders 14 increases, the scissor lever 11 unfolds, pushing the connecting plate 15 and the hydraulic telescopic rod 16 upward, thus increasing the distance between the cutting devices. Conversely, when the distance between the sliders 14 decreases, the scissor lever 11 retracts, the hydraulic telescopic rod 16 moves downward, and the distance between the cutting devices decreases. The hydraulic telescopic rod 16 adjusts its vertical height according to the extension and retraction state of the scissor lever 11, so that the contact pressure between the cutting blade 19 and the film is adapted to the current slitting requirements. Finally, the rotary motor 17 is started, driving the cutting blade 19 to rotate at high speed. The hydraulic telescopic rod 16 presses down, causing the cutting blade 19 to cut into the film, completing the slitting action. The slitting film is then wound by the winding device.

[0031] In practical use, it is necessary to be able to adjust the winding speed in real time to prevent the film from loosening or breaking due to excessive tightness. To meet the above requirements, in this embodiment, the winding device includes a support plate 3, an electric telescopic rod 6, a rotating column 4, and a limiting motor 5. The support plate 3 is symmetrically arranged on both sides of the lower end of the front side wall of the machine 1. The rotating column 4 is on the inner side wall of the support plate 3. The electric telescopic rod 6 is at one end of the rotating column 4. The limiting motor 5 is on the outer side wall of one of the support plates 3. The rotating column 4 passes through the support plate 3 and is connected to the output end of the limiting motor 5. A clamping plate 7 is provided at one end of the electric telescopic rod 6. The limiting motor 5 drives the rotating column 4 to rotate and wind the film. The electric telescopic rod 6 pushes the clamping plate 7 to fix the core. The winding tension is adjusted in real time through the control panel 2 to ensure that the film is wound tightly and without deviation.

[0032] In actual use, it is necessary to reduce the defect rate caused by impurities being pressed into the cut during the slitting process. In order to meet the above requirements, in this embodiment, the surface of the auxiliary rod 10 is covered with a cleaning cotton layer.

[0033] In actual use, it is necessary to eliminate the static electricity generated by the friction between the film and the roller surface during winding to avoid dust adsorption. In order to meet the above requirements, in this embodiment, the surface of the winding device is coated with an antistatic coating.

[0034] In actual use, it is necessary to reduce the risk of equipment damage. In order to meet the above requirements, in this embodiment, the control panel 2 is equipped with an emergency stop button.
