Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cooling system technology, specifically relating to a cooling system for a plastic wire drawing machine. Background Technology
[0002] Plastic filament drawing machines use polypropylene and high-density ethylene as raw materials. After heating, extrusion, slitting, and stretching, flat filaments are formed and then wound up for circular looms to weave. Filament drawing machines have generally undergone multiple improvements and can use 100% recycled materials, powders, or granules to draw flat filaments. In the initial extrusion, the filament drawing machine extrudes a thin film, which is then cooled and cut to form filaments.
[0003] In conventional cooling systems, the film is moved forward in a single layer within the cooling tank. This type of system requires a relatively long cooling tank; otherwise, the cooling effect on the plastic film is poor. By adding guide rollers within the tank, the film can pass over the guide rollers in one go, resulting in multiple layers of film within the tank, thus improving the cooling effect. However, the film is not easy to pass through the guide rollers, affecting the efficiency of film passing through. Utility Model Content
[0004] The purpose of this invention is to provide a cooling system for a plastic wire drawing machine, which can automatically wind plastic film and facilitate the threading of plastic film, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling system for a plastic wire drawing machine, comprising a cooling water tank and a guiding assembly, wherein there are two guiding assemblies, which are respectively disposed at the top of both ends of the cooling water tank. A folding assembly is disposed inside the cooling water tank, the folding assembly comprising a mounting frame fixedly connected inside the cooling water tank, the top of the mounting frame being rotatably connected to equidistantly distributed fixed rollers, and a movable roller structure being disposed between two adjacent fixed rollers, the movable roller structure being slidably connected to the mounting frame.
[0006] Furthermore, the guiding component includes a base plate fixedly connected to the end of the cooling water tank, with mounting plates fixedly connected to both ends of the base plate, and two guide rollers distributed vertically rotatably connected between the two mounting plates.
[0007] Furthermore, the mounting frame has equally spaced mounting slots on both sides, and the mounting slots on both sides of the mounting frame are arranged one-to-one.
[0008] Furthermore, notches are provided at the top of both ends of the mounting bracket.
[0009] Furthermore, the movable roller structure includes a connecting plate and a top plate. The top plate is fixedly connected to the top of the mounting frame, and both ends of the connecting plate are fixedly connected to sliding plates. The two sliding plates are slidably connected inside the two corresponding mounting slots.
[0010] Furthermore, a multi-stage telescopic rod is provided in the middle of the top plate, one end of which is fixedly connected to the top of the connecting plate, and a rotating roller is rotatably connected between the two sliding plates.
[0011] Furthermore, a limiting plate is fixedly connected to one end of the slide plate, and the limiting plate is slidably connected to one side of the outer wall of the mounting frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are: when inserting the plastic film, the rotating roller is raised, and the plastic film only needs to be passed through the gap between the bottom end of the rotating roller and the top end of the fixed roller. During the descent of the rotating roller, the plastic film is pressed down, so that the plastic film passes around the top end of the fixed roller and the bottom end of the rotating roller, realizing the automatic winding of the plastic film and facilitating the insertion of the plastic film.

Detailed Implementation
[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figure 1 and2 As shown, a cooling system for a plastic drawing machine includes a cooling water tank 1 and a guide assembly 2. There are two guide assemblies 2, which are respectively set at the top of both ends of the cooling water tank 1. A folding assembly 3 is provided inside the cooling water tank 1. The folding assembly 3 includes a mounting frame 31 fixedly connected inside the cooling water tank 1. The top of the mounting frame 31 is rotatably connected to equidistant fixed rollers 32. A movable roller structure 33 is provided between two adjacent fixed rollers 32. The movable roller structure 33 is slidably connected to the mounting frame 31.
[0021] According to the above structure, during use, the plastic film extruded by the extruder passes through one of the guide components 2, and then passes around several mounting frames 31 and fixed rollers 32 in sequence, so that the plastic film stays in the cooling water tank 1 for a longer time, thereby improving the cooling effect. It can also reduce the length of the cooling water tank 1 and reduce the space occupied by the cooling water tank 1.
[0022] like Figure 1 As shown, the guide assembly 2 includes a base plate 21 fixedly connected to the end of the cooling water tank 1. Mounting plates 22 are fixedly connected to both ends of the base plate 21. Two guide rollers 23 distributed vertically are rotatably connected between the two mounting plates 22.
[0023] According to the above structure, when in use, the plastic film is passed between the two guide rollers 23, and the guide rollers 23 play the role of guiding the plastic film in a different direction.
[0024] like Figure 3 As shown, mounting slots 311 are provided at equal intervals on both sides of the mounting bracket 31, and the mounting slots 311 on both sides of the mounting bracket 31 are provided one-to-one. The top of both ends of the mounting bracket 31 is provided with notches 312.
[0025] According to the above structure, the movable roller structure 33 moves up and down along the mounting frame 31, which improves the stability of the movable roller structure 33's movement. The notch 312 can reduce the height of the end of the cooling water tank 1, thus facilitating the plastic film to pass through the mounting frame 31.
[0026] like Figure 3 and 4 As shown, the movable roller structure 33 includes a connecting plate 331 and a top plate 332. The top plate 332 is fixedly connected to the top of the mounting frame 31. Both ends of the connecting plate 331 are fixedly connected to sliding plates 334. The two sliding plates 334 are slidably connected to the interiors of the two corresponding mounting slots 311. A multi-stage telescopic rod 333 is provided in the middle of the top plate 332. One end of the multi-stage telescopic rod 333 is fixedly connected to the top of the connecting plate 331. A rotating roller 335 is rotatably connected between the two sliding plates 334. A limiting plate 336 is fixedly connected to one end of the sliding plate 334. The limiting plate 336 is slidably connected to one side of the outer wall of the mounting frame 31.
[0027] According to the above structure, when inserting the plastic film, the connecting plate 331, along with the sliding plate 334, the rotating roller 335, and the limiting plate 336, are raised together by the multi-stage telescopic rods 333 until the bottom of the rotating roller 335 exceeds the top of the fixed roller 32 by 5-10 cm. At this time, the plastic film only needs to be passed through the gap between the bottom of the rotating roller 335 and the top of the fixed roller 32. After the plastic film passes through the gap, the multi-stage telescopic rods 333 extend sequentially from back to front, lowering the rotating roller 335. During the descent, the rotating roller 335 presses down on the plastic film, thereby allowing the plastic film to pass around the top of the fixed roller 32 and the bottom of the rotating roller 335, realizing the automatic winding of the plastic film and facilitating the insertion of the plastic film.
[0028] The working principle of this utility model is as follows: When in use, the plastic film is passed through the two guide rollers 23. The guide rollers 23 play the role of guiding the plastic film in a different direction. The notch 312 can reduce the height of the end of the cooling water tank 1, thus making it easier for the plastic film to pass through the mounting frame 31. When the plastic film is passed through, the connecting plate 331, together with the sliding plate 334, the rotating roller 335 and the limiting plate 336, are raised together by the multi-stage telescopic rods 333 until the bottom of the rotating roller 335 exceeds the top of the fixed roller 32 by 5-10 cm. At this time, the plastic film only needs to pass through the gap between the bottom of the rotating roller 335 and the top of the fixed roller 32. After the plastic film passes through the gap, the multi-stage telescopic rods 333 extend from back to front in sequence, lowering the rotating roller 335. During the descent, the rotating roller 335 presses down on the plastic film, so that the plastic film passes around the top of the fixed roller 32 and the bottom of the rotating roller 335, realizing the automatic winding of the plastic film and making it easy to pass through the plastic film.
[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
