Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle production, in particular to a wire drawing cooling device used for plastic particle production. Background Art

[0002] During the plastic pellet production process, the molten material, after being heated and plasticized, is extruded through the screw and die of an extruder, forming a preliminary filament. The extruded filament is then further stretched and processed by the drawing mechanism of a wire drawing machine. The wire drawing machine uses high-speed rotating rollers or a stretching device to apply a pulling force to the filament, making it thinner and stronger. During the stretching process, the strip material passes through a cooling device to quickly cool and solidify.

[0003] Publication No. CN206825887U provides a plastic wire drawing cooling device, comprising a plurality of water troughs arranged in sequence from front to back along the feed direction of the filamentary plastic, wherein the water troughs are arranged in sequence from front to back along the feed direction of the filamentary plastic, wherein a plurality of underwater conveying rollers are arranged in sequence from front to back within the water troughs, wherein an above-water conveying roller is provided between any two adjacent water troughs, wherein a first cooling fan is provided above the above-water conveying roller, and a second cooling fan is provided at the front end of the first water trough and the rear end of the last water trough. The utility model has a simple and reasonable structural design, good cooling effect, high efficiency and convenience, and has broad application prospects. Although the product has good cooling effect and high efficiency and convenience, the material is soft and easily causes the material to bend and contact the water in the second water trough, making it inconvenient to dry the water on the material, which can easily lead to errors in material conveying. The conventional method of adjusting the conveying rollers requires workers to use tools to disassemble and adjust the height to the appropriate position before fixing them, which reduces the cooling effect of the material and reduces the convenience of adjusting the winding roller. The practicality is poor and needs to be improved. Summary of the Invention

[0004] In response to the problems existing in the prior art, the utility model provides a wire drawing cooling device for plastic particle production, which can quickly adjust the height of the conveyor roller and can directly adjust the height by hand, thereby improving the convenience of adjusting the height of the conveyor roller and having high practicality.

[0025] like Figures 1 to 5 As shown, the present application provides a drawing cooling device for the production of plastic particles, which is arranged between an extrusion mechanism and a drawing mechanism, and is used to cool the extruded and drawn filamentous plastic. The device includes a first water tank 1 and a second water tank 2 arranged on a fixed frame 3 in sequence along the drawing direction. Cooling water is provided in the first water tank 1, and both the first water tank 1 and the second water tank 2 are provided with a water outlet valve 14;

[0026] The first water trough 1 and the second water trough 2 are both provided with a conveying roller 9 through a mounting base 16. Specifically, the conveying roller 9 includes a roller shaft and a roller wheel. The roller wheel is rotatably provided on the roller shaft. The mounting base 16 includes a mounting frame 6 mounted on the water trough. The upper end surface of the mounting frame 6 is provided with two supporting sleeves 7 opposite to each other along the length direction of the mounting frame 6. A lifting frame 8 is inserted into each supporting sleeve 7. The roller shaft ends of the conveying roller 9 are respectively provided in the lifting frames 8 on the corresponding sides.

[0027] The lifting frame 8 is provided with a plurality of adjustment sockets in the vertical direction, and the support sleeve 7 is provided with a plug-in component. The support sleeve 7 and the lifting frame 8 cooperate with each other through the plug-in component and the adjustment sockets to achieve height adjustment of the lifting frame 8.

[0028] Specifically, the plug-in component includes an insertion rod 11, which passes through the support sleeve 7 and cooperates with the adjustment socket on the lifting frame 8. The end of the insertion rod 11 away from the lifting frame 8 extends outward and is provided with a pulling portion 12 for pulling.

[0029] The insertion rod 11 is sleeved with a tension spring 13, one end of which is connected to the support sleeve 7 and the other end is connected to the drawing portion 12. This makes it easier to control the movement and positioning of the insertion rod 11, improves work efficiency and accuracy, and prevents the insertion rod 11 from suddenly losing control or being damaged due to external forces.

[0030] Furthermore, a card slot is provided on the inner side wall of the lifting frame 8, and a card block 15 is provided at the roller shaft end of the conveying roller 9 to cooperate with the card slot. The card block 15 cooperates with the card slot to achieve the card connection of the roller shaft end of the conveying roller 9 in the lifting frame 8.

[0031] A mounting seat 16 is provided on the upper surface of the lifting frame 8, and the mounting seat 16 is provided with a push plate 18 that can move axially along the conveying roller 9. A limiting rod 17 is provided on the end surface of the push plate 18 facing the block 15. The limiting rod 17 passes through the mounting seat 16 and is inserted into the limiting hole of the block 15. A spring 19 is provided between the end surface of the push plate 18 on the installation side of the limiting rod 17 and the mounting seat 16.

[0032] Furthermore, a fixing plate 4 is mounted on the first water tank 1 near the extrusion mechanism. A thermometer 5 is mounted on the fixing plate 4 for measuring the temperature of the cooling water in the first water tank 1. This allows for real-time and accurate monitoring of the cooling water temperature in the first water tank 1, ensuring that the cooling water remains within an appropriate range, thereby ensuring the stability of the wire drawing process and the consistency of product quality.

[0033] Preferably, a handle 10 is provided on the upper end surface of the lifting frame 8 .

[0034] Specifically, a first conveying roller 9 is mounted on the first water trough 1 away from the extrusion mechanism side; four groups of conveying rollers 9 are provided on the second water trough 2, two groups of conveying rollers 9 are respectively provided at both ends of the second water trough 2, and the other two groups of conveying rollers 9 are provided on the second water trough 2 close to the stretching mechanism side.

[0035] Working principle: The molten material after heating and plasticization is extruded through the extrusion mechanism, and the extruded filaments are further stretched and processed through the stretching mechanism of the wire drawing machine. The filamentary material is immersed in the cooling water in the first water tank 1 for cooling and solidification, and is moved out of the first water tank 1 through the first conveying roller 9 of the first water tank 1, and then moved to the conveying roller 9 of the second water tank 2. The water on the filamentary material drops to the position of the second water tank 2 to dry the material. When it is necessary to drain the water inside the first water tank 1 and the second water tank 2, the waste water can be discharged through the outlet valve 14.

[0036] To adjust the height of the lifting frame 8, first grasp the pull portion 12 and pull it, causing the pull portion 12 to move the insertion rod 11, disengaging the insertion rod 11 from the insertion hole of the lifting frame 8. Then, grasp the handle 10 and move it upward or downward, causing the handle 10 to move the lifting frame 8 up and down, thereby moving the conveyor roller 9 to the appropriate height. After that, by releasing the pull portion 12, the tension spring 13 drives the insertion rod 11 into the insertion hole of the lifting frame 8, thereby fixing the height of the lifting frame 8.

[0037] When it is necessary to dismantle and replace some dirty or damaged conveyor rollers 9, the push plate 18 can be grasped and pulled, so that the push plate 18 drives the limiting rod 17 to move away from the block 15, so that the limiting rod 17 slides from the inside of the block 15 into the mounting seat 16, and then the conveyor roller 9 can be grasped and pulled, so that the conveyor roller 9 drives the blocking block 15 to slide out of the slot of the lifting frame 8, so that the conveyor roller 9 can be smoothly disassembled. After that, the blocking block 15 on the replaced conveyor roller 9 is aligned with the slot of the lifting frame 8 and pressed, so that the blocking block 15 slides into the slot of the lifting frame 8. When the blocking block 15 slides into the slot of the lifting frame 8, the spring 19 drives the push plate 18 and the limiting rod 17 to move, so that the limiting rod 17 slides from the inside of the mounting seat 16 into the limiting hole of the blocking block 15, and the conveyor roller 9 is installed.

[0038] Due to the adoption of the above technical solution, by arranging the support sleeve 7, the lifting frame 8, the handle 10, the insertion rod 11, the pulling part 12, and the tension spring 13, the height of the conveying roller 9 can be quickly adjusted, avoiding the need for workers to disassemble the conveying roller 9 with the help of tools, adjust the height to a suitable position, and then fix it. The height can be adjusted directly by hand through the limit rod 17 and the upgrading frame, which improves the convenience of adjusting the height of the conveying roller 9 and is more practical.

[0039] By providing the clamping block 15, the mounting seat 16, the limiting rod 17, the push plate 18, and the spring 19, the conveying roller 9 can be replaced more conveniently, avoiding the need for workers to use tools to disassemble and replace the conveying roller 9. The clamping block 15 and the limiting rod 17 can make the conveying roller 9 replaceable more quickly and more practical.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
