Description

Technical Field

[0001] This utility model relates to the field of PVC film processing technology, and in particular to a high-efficiency PVC film stretching and forming device. Background Technology

[0002] PVC's main component is polyvinyl chloride, a slightly yellowish, translucent material with a glossy appearance. Its transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is classified as soft or rigid PVC. Soft PVC products are flexible and tough, with a sticky feel, while rigid PVC products have a harderness than low-density polyethylene but lower than polypropylene, and may exhibit whitening at bending points. Common products include: sheets, pipes, shoe soles, toys, doors and windows, wire sheathing, stationery, etc. It is a polymer material in which one chlorine atom replaces one hydrogen atom in polyethylene.

[0003] During PVC film stretching, the gap between the stretching rollers is not adjustable, making it inconvenient to stretch films of different thicknesses. Furthermore, water droplets inevitably appear on the surface of the film during processing, and failure to clean them in time will adversely affect subsequent operations and cause unnecessary trouble. To address this, we have designed a high-efficiency PVC film stretching and forming device. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency PVC film stretching and forming device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency PVC film stretching and forming device includes a housing. A front side plate is detachably connected to the front side of the housing. Two sets of adjusting components are provided on the upper part of the rear inner wall of the housing. Each set of adjusting components is connected to a stretching roller. A fixed roller is provided directly below the stretching roller. Two heating mounting plates are provided between the two stretching rollers. Two cooling mounting plates are provided on the upper right side of the rear inner wall of the housing. Two sets of guide rollers are symmetrically provided on the left and right sides of the two cooling mounting plates. A feed port for PVC film to pass through is opened on the left side surface of the housing. A discharge port for PVC film to exit is opened on the right side surface of the housing. A guide roller is provided inside the housing and on the side near the discharge port. A second scraper is provided above the left side of the guide roller. A first scraper is provided above the left side of the second scraper. The first scraper abuts against the upper surface of the PVC film, and the second scraper abuts against the lower surface of the PVC film.

[0007] As a preferred embodiment of this utility model: the adjustment component includes a fixed plate fixedly disposed on the inner wall of the rear side of the box, a sliding groove is opened on the front surface of the fixed plate in the vertical direction, a threaded rod is rotatably disposed between the upper and lower inner walls of the sliding groove, a slider is threaded on the outer thread of the threaded rod, the slider is slidably disposed inside the sliding groove, a connecting plate is fixedly disposed on the front surface of the slider, a lifting block is disposed at the bottom of the connecting plate, the stretching roller is rotatably disposed on the lifting block through a bearing, and a driving component corresponding to the adjustment component is disposed on the top of the box.

[0008] As a further preferred embodiment of this utility model: the driving component includes a drive motor fixedly mounted on the top of the housing, the output shaft of the drive motor is connected to a reducer, the transmission shaft of the reducer extends vertically downwards into the interior of the housing and is connected to a drive shaft, and the bottom end of the drive shaft is connected to the top end of the threaded rod.

[0009] As a further preferred embodiment of this utility model: each group of guide rollers consists of two rollers, which are symmetrically distributed vertically, and the guide rollers are rotatably mounted on the box body via bearings.

[0010] As a further preferred embodiment of this utility model: the two cooling mounting plates and the two heating mounting plates are symmetrically distributed vertically, with a cooling device installed inside the cooling mounting plate and a heating device installed inside the heating mounting plate.

[0011] As a further preferred embodiment of this utility model: the fixed roller is rotatably mounted on the box body via a bearing.

[0012] The beneficial effects of this utility model are as follows: When in use, the drive motor can drive the drive shaft and the threaded rod to rotate together, which in turn drives the slider to move up and down. Then, the connecting plate drives the lifting block and the stretching roller to move up and down. Furthermore, since the thickness of different PVC films is relatively thin, the device reduces the speed of the drive motor by setting a reducer, which makes it easier to control the stretching roller to move up and down slowly. This allows for better and more precise control of the gap between the stretching roller and the fixed roller, making it suitable for PVC films of varying thicknesses and improving the practicality of the device. During the reinforcement process, water mist and droplets inevitably appear on the surface of the PVC film. A first scraper and a second scraper are respectively provided on the upper and lower surfaces of the PVC film near the guide roller, which can scrape off the water stains on the upper and lower surfaces of the PVC film, avoiding trouble for subsequent operations.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a high-efficiency PVC film stretching and forming device includes a housing 1. A front side plate is detachably connected to the front side of the housing 1. Two sets of adjusting components are provided on the upper part of the rear inner wall of the housing 1. Each set of adjusting components is connected to a stretching roller 4. A fixed roller 13 is provided directly below the stretching roller 4. The fixed roller 13 is rotatably mounted on the housing 1 via bearings. Two heating mounting plates 12 are provided between the two stretching rollers 4. Two cooling mounting plates 7 are provided on the upper right side of the rear inner wall of the housing 1. Two sets of guide rollers 8 are symmetrically arranged on the left and right sides of the mounting plate 7. The left side surface of the box body 1 is provided with an inlet 3 for the PVC film to pass through, and the right side surface of the box body 1 is provided with an outlet 2 for the PVC film to pass through. Inside the box body 1 and on the side near the outlet 2, there is a guide roller 11. A second scraper 10 is provided on the upper left of the guide roller 11, and a first scraper 9 is provided on the upper left of the second scraper 10. The first scraper 9 abuts against the upper surface of the PVC film, and the second scraper 10 abuts against the lower surface of the PVC film.

[0021] The adjustment assembly includes a fixed plate 17 fixedly installed on the inner rear wall of the housing 1. A groove 19 is opened vertically on the front surface of the fixed plate 17. A threaded rod 21 is rotatably provided between the upper and lower inner walls of the groove 19. A slider 20 is threaded on the outside of the threaded rod 21. The slider 20 is slidably disposed inside the groove 19. A connecting plate 22 is fixedly provided on the front surface of the slider 20. A lifting block 18 is provided at the bottom of the connecting plate 22. The stretching roller 4 is rotatably disposed on the lifting block 18 through a bearing. A driving component corresponding to the adjustment assembly is provided on the top of the housing 1.

[0022] The driving component includes a drive motor 5 fixedly mounted on the top of the housing 1. The output shaft of the drive motor 5 is connected to a reducer 6. The transmission shaft of the reducer 6 extends vertically downwards into the interior of the housing 1 and is connected to a drive shaft 16. The bottom end of the drive shaft 16 is connected to the top end of the threaded rod 21.

[0023] Each set of guide rollers 8 consists of two rollers, which are symmetrically distributed vertically. The guide rollers 8 are mounted on the housing 1 via bearings.

[0024] The two cooling mounting plates 7 and the two heating mounting plates 12 are symmetrically distributed vertically.

Any structure that can reasonably achieve the functions of heating and cooling is acceptable.

[0025] Specifically, in use, the drive motor 5 drives the drive shaft 16 and the threaded rod 21 to rotate, which in turn drives the slider 20 to move up and down. This, in turn, drives the lifting block 18 and the stretching roller 4 to move up and down via the connecting plate 22. Furthermore, since the thickness of different PVC films is relatively thin, the device reduces the speed of the drive motor 5 by setting the reducer 6, which facilitates the slow up and down movement of the stretching roller 4. This allows for more precise control of the gap between the stretching roller 4 and the fixed roller 13, making it suitable for PVC films of varying thicknesses and improving the practicality of the device. During the reinforcement process, water droplets inevitably appear on the surface of the PVC film. The first scraper 9 and the second scraper 10 are respectively provided on the upper and lower surfaces of the PVC film near the guide roller 11, which can scrape off the water stains on the upper and lower surfaces of the PVC film to avoid trouble for subsequent operations.
