Technical Field
[0001] This utility model relates to the field of PVC film production technology, specifically a winding and cutting device based on environmentally friendly PVC film production. Background Technology
[0002] In today's era where environmental protection is increasingly valued, environmentally friendly PVC film, with its excellent flexibility, corrosion resistance, and recyclability, is widely used in packaging, construction, agriculture, and other fields. As market demand for environmentally friendly PVC film continues to increase, higher requirements are being placed on its production efficiency and product quality.
[0003] According to announcement number CN 218707624 U, a winding structure for a biodegradable plastic film production device is disclosed, relating to the field of winding structures, including a support component, on which a transmission component is connected.
[0004] This device, through the coordinated use of its supporting components, transmission components, positioning support components, and discharge support components, can not only wind up the plastic film but also eject the wound film roller. Furthermore, three connecting rods allow one rod to drive the winding cylinder to rotate and wind the film, while the other two rods eject the wound film roller. This allows for controlled production rhythm and orderly production, thereby improving efficiency. It solves the problem of existing winding structures that can only wind the produced film, requiring manual replacement of the winding cylinder and wound film roller, which is time-consuming and inefficient. However, this device lacks a film cutting device, which is an indispensable key piece of equipment in the production of environmentally friendly PVC film. Utility Model Content

The first guide rod provides support for the lifting plate, so that the lifting plate can be raised and lowered stably.
[0009] Preferably, the output end of the first servo motor is fixedly connected to the front end of the lead screw.
[0010] Preferably, the moving block has a hole on its front side that matches the limiting rod, and the moving block is slidably connected to the surface of the limiting rod through the hole. The limiting rod limits the moving block, so that the moving block moves back and forth as the lead screw rotates.

[0014] Compared with the prior art, this utility model provides a winding and cutting device based on environmentally friendly PVC film production, which has the following beneficial effects:
[0015] This winding and cutting device, based on environmentally friendly PVC film production, uses a film cutting mechanism driven by a first hydraulic cylinder to vertically raise and lower a lifting plate. This, combined with a rubber pressure strip, initially fixes the film, ensuring stability during the cutting process. The threaded connection between the lead screw and the moving block, along with the sliding limit of the limiting rod, allows the blade to move precisely back and forth, achieving high-precision cutting. The use of a first servo motor makes the lead screw rotation smoother and more controllable, further improving cutting accuracy and efficiency.
[0016] This winding and cutting device, based on environmentally friendly PVC film production, uses a winding mechanism driven by a second servo motor to drive a first pressure plate, which in turn works with a second pressure plate driven by a second hydraulic cylinder to achieve a stable clamping of the winding roller. The sliding connection between the second guide rod and the back of the fixed frame ensures the stability of the moving plate during its forward and backward movement, thereby ensuring the smooth operation of the winding roller during the winding process.

[0026] This utility model provides the following technical solution: Example
[0027] Please see Figure 1-3 This utility model provides a technical solution: a winding and cutting device based on environmentally friendly PVC film production, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a film cutting mechanism 3 provided on the top right side of the base 1, and a winding mechanism 4 provided on the top left side of the base 1.
[0028] The film cutting mechanism 3 includes a first fixed frame 31, which is fixedly connected to the top right side of the base 1. A first hydraulic cylinder 32 is fixedly connected to the top of the first fixed frame 31. A lifting plate 33 is fixedly connected to the output end of the first hydraulic cylinder 32. A first guide rod 34 is symmetrically fixedly connected to the top of the lifting plate 33 near the right side. A rubber pressure strip 35 is fixedly connected to the bottom of the lifting plate 33 near the left side. A second fixed frame 36 is fixedly connected to the bottom of the lifting plate 33. A lead screw 37 is rotatably connected to the front and rear sides near the top of the second fixed frame 36. A first servo motor 38 is fixedly connected to the front of the second fixed frame 36 near the top. Limit rods 39 are fixedly connected to the front and rear sides near the bottom of the second fixed frame 36. A moving block 311 is threadedly connected to the surface of the lead screw 37. A blade 312 is fixedly connected to the bottom of the moving block 311.
[0029] The top of the first fixed frame 31 has a hole that matches the first guide rod 34, and the surface of the first guide rod 34 is penetrated and slides up and down to connect to the hole. The first guide rod 34 will support the lifting plate 33, so that the lifting plate 33 can be raised and lowered stably.
[0030] The output end of the first servo motor 38 is fixedly connected to the front end of the lead screw 37.
[0031] The movable block 311 has a hole on its front that matches the limiting rod 39, and the movable block 311 is slidably connected to the surface of the limiting rod 39 through the hole. The limiting rod 39 limits the movable block 311, so that the movable block 311 moves back and forth as the lead screw 37 rotates. Example
[0032] Please see Figure 4-5 Furthermore, based on Example 1, a winding mechanism 4 is obtained.
[0033] The winding mechanism 4 includes a third fixed frame 41 and a winding roller 49. The third fixed frame 41 is fixedly connected to the top left side of the base 1. A second servo motor 42 is fixedly connected to the front of the third fixed frame 41 near the top. A first pressure plate 43 is fixedly connected to the output end of the second servo motor 42. A second hydraulic cylinder 44 is fixedly connected to the back of the third fixed frame 41. A moving plate 45 is fixedly connected to the output end of the second hydraulic cylinder 44. A rotating shaft 46 is rotatably connected to the front of the moving plate 45 near the top. A second pressure plate 47 is fixedly connected to the front end of the rotating shaft 46. Second guide rods 48 are symmetrically fixed to the left and right sides of the back of the moving plate 45 near the top.
[0034] The third fixing bracket 41 has a hole on its back near the top that matches the second guide rod 48, and the surface of the second guide rod 48 is penetrated and slidably connected to the hole, so that the first pressing plate 43 and the second pressing plate 47 clamp the take-up roller 49 more stably.
[0035] The take-up roller 49 is located between the first clamping plate 43 and the second clamping plate 47, and is clamped and fixed by the first clamping plate 43 and the second clamping plate 47.
[0036] In actual operation, when this device is used, the take-up roller 49 is placed between the first pressing plate 43 and the second pressing plate 47. The second hydraulic cylinder 44 is activated, and its output end pushes the moving plate 45 forward. The second guide rod 48 slides back and forth in the hole on the back of the third fixed frame 41 to ensure the stability of the moving plate 45. As the moving plate 45 moves, the second pressing plate 47 gradually approaches the first pressing plate 43 until it clamps and fixes the take-up roller 49. At this time, the second servo motor 42 is activated, and its output end drives the first pressing plate 43 to rotate, which in turn drives the take-up roller 49 to rotate, winding the film onto the take-up roller 49 to achieve film winding. After winding is completed, the first hydraulic cylinder 32 is activated, and its output end pushes the lifting plate 33 downward. The first guide rod 34 slides up and down in the hole at the top of the first fixed frame 31 to provide support and guidance, ensuring that the lifting plate 33 descends smoothly. When the lifting plate 33 descends to a certain position, the rubber strip 35 at the bottom presses and fixes the film to prevent displacement of the film during cutting. Subsequently, the first servo motor 38 starts, and its output drives the lead screw 37 to rotate. Since the moving block 311 is threadedly connected to the lead screw 37, and the limiting rod 39 limits the moving block 311, the moving block 311 moves back and forth along the limiting rod 39 when the lead screw 37 rotates. This drives the blade 312 fixed at the bottom of the moving block 311 to move along the direction of the film to be cut, thus completing the film cutting work. The second hydraulic cylinder 44 runs in the opposite direction, driving the moving plate 45 to move backward, releasing the clamp on the take-up roller 49, and the wound film can be removed.
