Description

Technical Field

[0001] This utility model relates to the field of PVC film production technology, specifically to a high-efficiency winding mechanism for PVC calendered film. Background Technology

[0002] The production of PVC film requires calendering, a process in which heated compounded rubber or PVC rubber is passed through the gap between two horizontally arranged, relatively rotating rollers to form semi-finished products such as sheets. During calendering, heated and plasticized thermoplastic plastic is passed through a series of heated rollers to continuously form films or sheets. In PVC rubber processing, the rubber compound can be calendered into sheets of a certain thickness and width, or patterns can be embossed onto the sheets for subsequent product molding. Calendering is also used to coat fabrics and steel cords with PVC, and to bond sheets together or sheets to coated fabrics. In plastics processing, calendering is mainly used to process PVC films and sheets, and to laminate them with fabrics to produce artificial leather, floor coverings, and waterproof membranes.

[0003] Traditional winding equipment typically consists of only a single winding assembly. During the winding process, once this assembly completes its winding task, the entire production line must be stopped for the winding roller to be replaced before a new round of winding can begin. This intermittent production mode results in a significant amount of time wasted on downtime and roller replacement preparation, leading to extremely low overall winding efficiency and making it impossible to meet the demands of large-scale, high-efficiency production. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency winding mechanism for PVC calendered film to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency PVC calendered film winding mechanism, comprising a base, on which a vertical plate is fixedly connected, and further comprising:

[0006] A winding assembly for winding PVC calendered film is mounted on an upright plate. An adjusting assembly for adjusting the position of the winding assembly is also mounted on the upright plate. A moving assembly for removing the wound PVC calendered film from the winding assembly is mounted on the base. A conveying assembly for conveying the PVC calendered film is also mounted on the base.

[0007] Preferably, the adjustment assembly includes a first motor fixedly mounted on a vertical plate, a rotating rod rotatably mounted on the vertical plate, the output end of the first motor being fixedly connected to the rotating rod, and a connecting seat being fixedly connected to the rotating rod.

[0008] Preferably, the winding assembly includes two second motors symmetrically fixedly mounted on a connecting seat, and two symmetrical rotating shafts rotatably mounted on the connecting seat. The rotating shafts are fixedly connected to the output ends of the second motors, and a winding roller is sleeved on the outer side of the rotating shafts.

[0009] Preferably, a limiting block is fixedly connected to the rotating shaft, and a limiting groove is formed on the inner wall of the take-up roller.

[0010] Preferably, the movable component includes a hydraulic rod fixedly mounted on the upright plate, a connecting plate fixedly connected to the piston rod of the hydraulic rod, an arc-shaped push rod fixedly connected to the connecting plate, a sliding rod fixedly connected to the top of the base, and the connecting plate slidably mounted on the sliding rod.

[0011] Preferably, the transmission component includes a bracket fixedly mounted on a base, and a rotating roller is rotatably mounted on the bracket.

[0012] Preferably, protective rods are rotatably mounted on both sides of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features two sets of winding components. The first motor drives the connecting seat to rotate, enabling alternating winding and avoiding downtime when using a single winding component. This significantly improves winding efficiency. The design uses a hydraulic rod to push an arc-shaped push rod, which can quickly push the wound winding roller off the rotating shaft, facilitating convenient replacement of the winding roller and reducing manual operation difficulty and time costs. The transmission component is equipped with a rotating roller and a protective rod. The rotating roller can smoothly transport the wound PVC calendered film, while the protective rod can effectively prevent the film from falling, ensuring the stability and safety of the transmission process.

The adjusting assembly 3 is used to alternately adjust the positions of the two winding assemblies 4 to improve winding efficiency. A moving assembly 5 is installed on the base 1 to move the wound PVC calendered film from the winding assembly 4. A transmission assembly 6 is also installed on the base 1 to transport the PVC calendered film. The moving assembly 5 moves a set of wound PVC calendered films onto the transmission assembly 6, and then the transmission assembly 6 moves them out and stores them.

[0024] The adjusting assembly 3 includes a first motor 31 fixedly mounted on the upright plate 2, a rotating rod 32 rotatably mounted on the upright plate 2, the output end of the first motor 31 being fixedly connected to the rotating rod 32, and a connecting seat 33 fixedly connected to the rotating rod 32; the winding assembly 4 includes two second motors 41 symmetrically fixedly mounted on the connecting seat 33, two symmetrical rotating shafts 42 rotatably mounted on the connecting seat 33, the rotating shafts 42 being fixedly connected to the output ends of the second motors 41, and a winding roller 43 sleeved on the outer side of the rotating shafts 42; a limit block is fixedly connected to the rotating shaft 42. 8. A limiting groove 9 is provided on the inner wall of the take-up roller 43; the first motor 31 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the connecting seat 33 to rotate. A set of take-up components 4 are installed at both ends of the connecting seat 33. When one set of take-up components is finished, it is adjusted to the lower part, and the other set of take-up components 4 continues to take-up. When taking up, the limiting block 8 on the take-up roller 43 is aligned and installed in the limiting groove 9 on the rotating shaft 42. The second motor 41 drives the rotating shaft 42 and the take-up roller 43 to rotate, and the PVC calendered film is taken up on the take-up roller 43.

[0025] The moving component 5 includes a hydraulic rod 51 fixedly mounted on the upright plate 2. A connecting plate 52 is fixedly connected to the piston rod of the hydraulic rod 51. An arc-shaped push rod 53 is fixedly connected to the connecting plate 52. A slide rod 54 is fixedly connected to the top of the base 1. The connecting plate 52 is slidably mounted on the slide rod 54. The transmission component 6 includes a bracket 61 fixedly mounted on the base 1. A rotating roller 62 is rotatably mounted on the bracket 61. Protective rods 7 are rotatably mounted on both sides of the bracket 61. After a set of winding rollers 43 finishes winding, they move to the arc-shaped push rod 53. The hydraulic rod 51 pushes the arc-shaped push rod 53 and the connecting plate 52 to move on the slide rod 54, pushing the winding roller 43 off the rotating shaft 42 and onto the rotating roller 62. The rotating roller 62 moves the wound PVC calendered film away. The protective rods 7 can protect the PVC calendered film and prevent it from falling off the bracket 61.

[0026] Working principle: Align the limiting block 8 on the take-up roller 43 with the limiting groove 9 on the rotating shaft 42. Start the second motor 41, which drives the rotating shaft 42 to rotate, thereby driving the take-up roller 43 to rotate and winding the PVC calendered film onto the take-up roller 43. After one set of take-up components 4 has finished winding, start the first motor 31, which drives the rotating rod 32 to rotate. The rotating rod 32 drives the connecting seat 33 to rotate, adjusting the finished take-up component 4 to the lower position. Another set of take-up components 4 continues to perform winding, thereby improving efficiency. Regarding the winding efficiency, after a set of winding rollers 43 finishes winding, they move to the arc-shaped push rod 53 and activate the hydraulic rod 51. The hydraulic rod 51 pushes the piston rod, which in turn moves the connecting plate 52 on the slide rod 54. The connecting plate 52 then moves the arc-shaped push rod 53, pushing the winding roller 43 off the rotating shaft 42. The pushed-off winding roller 43 moves onto the rotating roller 62, which rotates to move the wound PVC calendered film away. At the same time, the protective rods 7, which are rotatably installed on both sides of the bracket 61, protect the PVC calendered film and prevent it from falling off the bracket 61.
