Abstract
Description
Technical Field
[0001] This utility model relates to a winding device, specifically a winding device for automated PVC film production. Background Technology
[0002] PVC film is mainly composed of polyurethane, with other components added to enhance its heat resistance, toughness, and ductility. It is a popular and widely used synthetic material in the world today.
[0003] In related technologies, during film production, a core is typically fitted onto a take-up shaft, with the sidewall of the take-up shaft tensioned against the inner wall of the core. The film is then wound around the take-up shaft, which drives the core to rotate synchronously, thus winding the film onto the core and achieving the film winding operation. However, existing PVC film winding equipment involves cumbersome assembly and disassembly procedures for the take-up rollers, making it inconvenient to replace them and affecting the winding efficiency after processing. Therefore, this application designs a winding device for automated PVC film production. Utility Model Content
[0004] The main objective of this disclosure is to provide a winding device for automated PVC film production, so as to effectively solve the problems raised by the inventors in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A PVC film automated production winding device includes a support frame. A winding shaft is rotatably mounted on the front side of the support frame, and a winding base is fixedly mounted on the rear end surface of the winding shaft. A winding roller is sleeved on the winding shaft and is detachably connected to the winding base. Two symmetrically arranged stationary guide rollers are provided on the front side of the support frame, and a dynamic guide roller is movably arranged between the stationary guide rollers and the winding roller. An arc-shaped cover is provided on the front side between the two rollers and is located below the winding roller. A blocking mechanism is provided inside the arc-shaped cover.
[0007] Preferably, the front of the winding chassis is fixedly equipped with three protrusions arranged in a ring array, and the winding roller is provided with three limiting holes arranged in a ring array, with each of the protrusions inserted into the limiting holes.
[0008] Preferably, the blocking mechanism includes a swing shaft and a baffle plate. The swing shaft is rotatably mounted on a bracket and located inside an arc-shaped cover. The baffle plate is fixedly mounted on the swing shaft, and a smooth pad is fixedly connected to the back of the baffle plate. The smooth pad slides in contact with the front of the winding roller.
[0009] Preferably, a torsion spring is fixedly connected between the baffle and the bracket, and the torsion spring is sleeved on the swing shaft.
[0010] Preferably, a drive motor is fixedly mounted on the bracket, and a small gear is fixedly connected to the output end of the drive motor. A large gear is fixedly mounted on the outer side of the winding chassis, and the large gear meshes with the small gear for transmission.
[0011] Preferably, the bracket has a sliding groove, and an adjusting screw is rotatably installed in the sliding groove. A limit slider is threaded on the adjusting screw, and the limit slider is slidably installed in the sliding groove. One end of the adjusting screw extends out of the bracket and is fixedly connected to a handwheel. A dynamic guide roller is fixedly connected to the portion of the limit slider located in the sliding groove.
[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:
[0013] (i) In this application, after the PVC film is produced, it passes around the stationary guide roller and the dynamic guide roller and is wound onto the take-up roller. During the winding, the drive motor works, and under the meshing transmission of the small gear and the large gear, the large gear drives the take-up chassis to rotate. Because the protrusion is inserted into the limiting hole, the take-up roller can rotate with the take-up chassis, thereby automatically winding the PVC film. Furthermore, stationary guide rollers and dynamic guide rollers are provided on both sides, so that the winding direction is not distinguished and both sides can be used.
[0014] (ii) In this application, the take-up roller is sleeved on the winding shaft, and the baffle is blocked in front of the take-up roller, so that the smooth pad slides into contact with the front side of the take-up roller. On the one hand, it does not affect the rotation of the take-up chassis, and on the other hand, it prevents the take-up roller from detaching from the winding shaft. This connection method also facilitates the disassembly and assembly of the take-up roller, and makes it easy to replace the empty take-up roller.
[0015] (III) In this application, rotating the handwheel can rotate the adjusting screw, thereby allowing the limiting slider to slide in the groove, so that the position of the dynamic guide roller can be changed. The position of the dynamic guide roller determines the tension of the PVC film during winding, so as to straighten the PVC film and make its winding smoother. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 The present invention provides the following embodiments:
[0024] A PVC film automated production winding device includes a support 1. A winding shaft 2 is rotatably mounted on the front of the support 1, and a winding base 3 is fixedly mounted on the rear surface of the winding shaft 2. A winding roller 4 is sleeved on the winding shaft 2, and the winding roller 4 is detachably connected to the winding base 3. Two symmetrically arranged stationary guide rollers 5 are provided on the front of the support 1, and a dynamic guide roller 6 is movably arranged between the stationary guide rollers 5 and the winding roller 4. An arc-shaped cover 7 is provided on the front between them, and the arc-shaped cover 7 is located below the winding roller 4. A blocking mechanism is provided inside the arc-shaped cover 7.
[0025] Specifically, the front of the winding chassis 3 is fixedly installed with three protrusions 301 arranged in a ring array, and the winding roller 4 is provided with three limiting holes 401 arranged in a ring array. Each protrusion 301 is inserted into each limiting hole 401. The blocking mechanism includes a swing shaft 8 and a baffle 9. The swing shaft 8 is rotatably mounted on the bracket 1 and located inside the arc-shaped cover 7. The baffle 9 is fixedly installed on the swing shaft 8, and a smooth pad 901 is fixedly connected to the back of the baffle 9. The smooth pad 901 slides in contact with the front of the winding roller 4.
[0026] Specifically, a torsion spring 801 is fixedly connected between the baffle 9 and the bracket 1, and the torsion spring 801 is sleeved on the swing shaft 8.
[0027] Specifically, a drive motor 10 is fixedly installed on the bracket 1, and a small gear 11 is fixedly connected to the output end of the drive motor 10. A large gear 12 is fixedly installed on the outside of the winding chassis 3, and the large gear 12 meshes with the small gear 11 for transmission.
[0028] Specifically, a drive motor 10 is fixedly installed on the bracket 1, and a small gear 11 is fixedly connected to the output end of the drive motor 10. A large gear 12 is fixedly installed on the outside of the winding chassis 3, and the large gear 12 meshes with the small gear 11 for transmission.
[0029] The specific implementation of this embodiment is as follows: After the PVC film is produced, it passes around the stationary guide roller 5 and the dynamic guide roller 6 and is wound onto the take-up roller 4. During winding, the drive motor 10 works, and under the meshing transmission of the small gear 11 and the large gear 12, the large gear 12 drives the take-up base 3 to rotate. Since the protrusion 301 is inserted into the limiting through hole 401, the take-up roller 4 can rotate together with the take-up base 3, thereby automatically winding the PVC film. The stationary guide roller 5 and the dynamic guide roller 6 are provided on both sides, so the winding direction is not distinguished and both sides can be used.
[0030] The take-up roller 4 is fitted onto the winding shaft 2, and the baffle 9 is positioned in front of the take-up roller 4, allowing the smooth pad 901 to slide into contact with the front side of the take-up roller 4. This does not affect the rotation of the take-up chassis 3, and also prevents the take-up roller 4 from detaching from the winding shaft 2. This connection method also facilitates the disassembly and assembly of the take-up roller 4 (when disassembling, rotate the baffle 9 to detach it from the front side of the take-up roller 4, and then pull the take-up roller 4 out of the winding shaft 2), thus making it easier to replace the empty take-up roller 4.
[0031] Rotating the handwheel 604 will cause the adjusting screw 602 to rotate, which in turn causes the limiting slider 603 to slide within the groove 601, allowing the position of the dynamic guide roller 6 to be changed. The position of the dynamic guide roller 6 determines the tension of the PVC film during winding, so as to straighten the PVC film and make its winding smoother.
