Abstract
Description
Technical Field
[0001] This utility model relates to the field of plasticizing and stretching machine technology, and more specifically, to a plasticizing and stretching machine with an anti-deviation structure. Background Technology
[0002] In the production of ultra-high molecular weight polyethylene (UHMWPE) films, in order to meet the required thickness, it is usually necessary to stretch the thicker films. Stretching reduces the thickness of the film and increases its length, thus meeting the preparation requirements. The plasticizing and stretching operation is usually carried out on a corresponding plasticizing and stretching machine.
[0003] Plasticizing and stretching machines typically have a corresponding winding shaft. As the shaft winds around the film, it stretches and winds the film. However, during this process, the lack of a corresponding anti-deviation structure can cause the film's position to shift, potentially leading to misalignment of the film wrapped around the shaft. This misalignment affects the film's normal plasticizing and stretching, as well as subsequent winding and use, disrupting the manufacturing process and causing inconvenience to the user. Therefore, we propose a plasticizing and stretching machine with an anti-deviation structure. Utility Model Content
[0004] The purpose of this invention is to provide a plasticizing and stretching machine with an anti-deviation structure to solve the defects mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A plasticizing and stretching machine with an anti-deviation structure includes a plasticizing and stretching machine body, a bypass shaft disposed on the plasticizing and stretching machine body, and a surrounding shaft disposed on the plasticizing and stretching machine body. A base plate is disposed on the plasticizing and stretching machine body, and an anti-deviation assembly is disposed on the base plate. The anti-deviation assembly includes two limiting discs sleeved on the surrounding shaft and slidably connected to the surrounding shaft, and two guide discs sleeved on the bypass shaft and slidably connected to the bypass shaft. A connecting rod is fixedly installed between the corresponding limiting discs and the guide discs. A vertical plate is fixedly installed at the bottom of the connecting rod, and a threaded sleeve is fixedly installed on the vertical plate. The anti-deviation assembly also includes a servo motor disposed on the base plate. A forward lead screw is fixedly installed at the end of the output shaft of the servo motor, and a reverse lead screw is fixedly installed at the end of the forward lead screw. The forward lead screw and the reverse lead screw pass through the corresponding threaded sleeves and are threadedly connected to the threaded sleeves.
[0007] Preferably, the limiting disk and the guide disk are used to perform anti-displacement limiting operations on the films on the bypass shaft and the surrounding shaft.
[0008] Preferably, the external threads on the surfaces of the forward lead screw and the reverse lead screw have opposite directions of rotation, so that the rotation of the forward lead screw and the reverse lead screw can drive the two connecting rods to move in opposite directions.
[0009] Preferably, a support plate is fixedly installed on the bottom surface of the base plate, and the servo motor is fixedly installed on the support plate to facilitate the support operation of the servo motor.
[0010] Preferably, a bearing seat is provided on the smooth section of the reverse lead screw, and the bearing seat is fixedly installed on the base plate, so as to facilitate further support operation of the reverse lead screw using the bearing seat.
[0011] Preferably, the base plate is provided with two mutually symmetrical sliding grooves, and a slider is fixedly installed on the bottom surface of the vertical plate. The slider is located in the sliding groove and is slidably connected to the sliding groove, so that the vertical plate moves more stably and smoothly when moving back and forth.
[0012] Preferably, the size of the slider is adapted to the size of the groove to ensure that the slider slides more stably and smoothly within the groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through its anti-deviation component, ensures that during use, the film is confined between the limiting plate and the guide plate under the blocking action of the limiting plate and the guide plate, thus achieving the effect of anti-deviation protection. This allows the film to be stretched and wound normally, making it convenient to use. It solves the problem that in conventional plasticizing stretching machines, during the process of wrapping the film around the winding shaft, the lack of a corresponding anti-deviation structure causes the film's position to shift, which in turn causes the film wrapped around the winding shaft to shift. After shifting, the normal plasticizing stretching and subsequent winding of the film are affected, affecting the normal progress of the preparation operation and causing inconvenience to the user.
[0015] 2. This utility model, through the setting of servo motors, forward lead screws, reverse lead screws and other components, facilitates the adjustment of the distance between the two vertical plates by the operation of the servo motor during use, and further realizes the adjustment of the distance between the two limit plates and the distance between the two guide plates, which is convenient for anti-deviation limit operation of films of different widths.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0024] Please see Figures 1-4 This utility model provides a technical solution: a plasticizing and stretching machine with an anti-deviation structure, including a plasticizing and stretching machine body 1, a bypass shaft 10 disposed on the plasticizing and stretching machine body 1, and a surrounding shaft 11 disposed on the plasticizing and stretching machine body 1. A base plate 12 is disposed on the plasticizing and stretching machine body 1, and an anti-deviation component 2 is disposed on the base plate 12. The anti-deviation component 2 includes two limiting disks 24 sleeved on the surrounding shaft 11 and slidably connected between the surrounding shaft 11, and two guide disks 25 sleeved on the bypass shaft 10 and slidably connected between the bypass shaft 10. The limiting disks 24 and guide disks 25 limit the film in the middle. The limiting disks 24 and guide disks 25 are used to perform anti-deviation limiting operation on the film on the bypass shaft 10 and the surrounding shaft 11.
[0025] Specifically, a connecting rod 28 is fixedly installed between the corresponding limiting plate 24 and the guide plate 25. A vertical plate 26 is fixedly installed at the bottom of the connecting rod 28, and a threaded sleeve 27 is fixedly installed on the vertical plate 26. The anti-deviation component 2 also includes a servo motor 20 set on the base plate 12. A forward lead screw 21 is fixedly installed at the end of the output shaft of the servo motor 20, and a reverse lead screw 22 is fixedly installed at the end of the forward lead screw 21. The forward lead screw 21 and the reverse lead screw 22 pass through the corresponding threaded sleeve 27 and are threadedly connected to the threaded sleeve 27. The external threads on the surfaces of the forward lead screw 21 and the reverse lead screw 22 have opposite directions of rotation, which causes the forward lead screw 21 and the reverse lead screw 22 to rotate, thereby driving the two connecting rods 28 to move in opposite directions, further driving the limiting plate 24 and the guide plate 25 to move, thereby adjusting the distance between the limiting plate 24 and the guide plate 25, which facilitates the use of the limiting plate 24 and the guide plate 25 to limit films of different widths and sizes.
[0026] In this embodiment, a support plate 13 is fixedly installed on the bottom surface of the base plate 12, and the servo motor 20 is fixedly installed on the support plate 13 to facilitate the support operation of the servo motor 20.
[0027] Furthermore, a bearing seat 23 is provided on the smooth section column at the end of the reverse lead screw 22. The smooth section column at the end of the reverse lead screw 22 is fixedly installed on the inner ring of the bearing inside the bearing seat 23. The bearing seat 23 is fixedly installed on the base plate 12, which facilitates further support operation of the reverse lead screw 22 using the bearing seat 23.
[0028] In addition, two symmetrical sliding grooves 121 are provided on the base plate 12, and a slider 29 is fixedly installed on the bottom surface of the vertical plate 26. The slider 29 is located in the sliding groove 121 and is slidably connected to the sliding groove 121, so that the vertical plate 26 moves more stably and smoothly when moving back and forth. The size of the slider 29 is adapted to the size of the sliding groove 121, ensuring that the slider 29 slides more stably and smoothly in the sliding groove 121.
[0029] It is worth noting that the servo motor 20 in this embodiment is a conventional technology and will not be described in detail here.
[0030] When using the plasticizing stretching machine with anti-deviation structure, after the film is laid on the bypass shaft 10 and wrapped around the bypass shaft 11, the servo motor 20 is connected to an external power supply and made to work. When the servo motor 20 works, the output shaft on it rotates in either the forward or reverse direction, which drives the forward lead screw 21 and the reverse lead screw 22 to rotate. The rotation of the forward lead screw 21 and the reverse lead screw 22 can drive the corresponding vertical plate 26 to move. The movement of the vertical plate 26 can adjust the distance between the two limit plates 24 and the distance between the two guide plates 25. By using the limit plates 24 and the guide plates 25 to block the side of the film, the anti-deviation limiting operation is achieved, which is convenient to use.
