Winding equipment for cotton spun yarn

Abstract

The utility model belongs to the technical field of cotton spinning yarn production, and particularly relates to cotton spinning yarn winding equipment which comprises a bottom plate. The second motor drives the U-shaped seat to rotate through the rotating shaft, the U-shaped seat drives the wind-up roller to rotate, the cotton-spun yarn starts to be wound on the wind-up roller gradually, the extrusion roller is tightly attached to the surface of a cotton-spun yarn roll all the time under elastic extrusion of the spring, and continuous and uniform pressure is applied to the wound cotton-spun yarn. The electric push rod drives the adjusting plate to move downwards, so that the adjusting plate compresses the unused spring, the spring is in a slightly compressed or semi-compressed state before being used, and the cotton spun yarn is prevented from being loosened in the winding process. The compression stroke of the compression roller is shortened, the damping elastic force of the spring in the compression state to the U-shaped plate is increased, and therefore the phenomenon that after long-time use, the elasticity of the spring becomes weak, and consequently the extrusion roller cannot normally compress cotton spun yarn is prevented.

Description

Technical Field

[0001] This utility model relates to the field of cotton spinning production technology, specifically to a winding device for cotton spinning. Background Technology

[0002] In the cotton spinning production and processing field, winding equipment is an important device in a key link, and its performance directly affects the final quality of cotton spinning products and their subsequent use effects.

[0003] Currently, while existing cotton spinning winding equipment on the market meets basic winding function requirements to a certain extent, a prominent and urgent problem has emerged in practical applications: the inability to effectively compact the cotton yarn during the winding process. Cotton yarn, as a soft and elastic fiber material, is prone to loosening during winding due to the lack of an effective compaction mechanism. Specifically, during winding, the cotton yarn is wrapped loosely layer by layer on the roll, lacking sufficient tightness and compression between yarns and layers. This loose winding method has multiple negative impacts. From a product quality perspective, loose cotton yarn rolls not only appear less neat and aesthetically pleasing, affecting the overall product image and market competitiveness, but more importantly, during subsequent transportation, storage, and use, loose yarn rolls are easily deformed and unraveled by slight external impacts, compression, or vibrations, leading to tangled yarn, broken ends, and other problems.

[0004] Therefore, we propose a winding device for cotton spinning to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a winding device for cotton spinning, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A cotton spinning take-up device includes a base plate. Two first L-shaped plates are provided on the top of the base plate. A rotating shaft is rotatably connected to one side of each first L-shaped plate, and a U-shaped seat is fixedly connected to the end of the rotating shaft. Take-up rollers are threadedly connected to the two U-shaped seats via multiple bolts. A second L-shaped plate is welded to the rear side of the base plate. Side plates are fixedly connected to both sides of the second L-shaped plate. Grooves are formed on the side plates, and L-shaped blocks are slidably connected to the grooves. The bottom of the two L-shaped blocks is fixedly connected to the same U-shaped plate. A squeezing roller is rotatably connected between the inner walls of the two sides of the U-shaped plate. An electric push rod is fixedly connected to the top inner wall of the second L-shaped plate. An adjusting plate is fixedly connected to the second output end of the electric push rod. Multiple springs are fixedly connected between the bottom of the adjusting plate and the top of the U-shaped plate. Two positioning rods are welded to the top inner wall of the second L-shaped plate. Limiting rods are slidably connected to the positioning rods, and the ends of the limiting rods are fixedly connected to the top of the U-shaped plate.

[0010] Furthermore, a rectangular hole is provided on the base plate, and a lead screw is rotatably connected between the inner walls of the two sides of the rectangular hole.

[0011] Furthermore, a connecting block is threaded onto the lead screw, the bottom of one of the two first L-shaped plates is fixedly connected to the top of the connecting block, and the bottom of the other of the two first L-shaped plates is fixedly connected to the top of the base plate.

[0012] Furthermore, a first motor is fixedly connected to the left side of the base plate, and the end of the lead screw extends outside the base plate and is fixedly connected to the output shaft of the first motor.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a winding device for cotton spinning, which has the following beneficial effects:

[0017] This invention utilizes a second motor to drive a U-shaped seat via a rotating shaft. The U-shaped seat then drives a take-up roller to rotate, causing cotton yarn to gradually wind onto the take-up roller. As the cotton yarn continues to wind onto the take-up roller, the yarn layer thickness gradually increases. Under the elastic compression of the spring, the squeeze roller remains tightly pressed against the surface of the cotton yarn roll, applying continuous and uniform pressure to the winding cotton yarn. This ensures tight adhesion and compression between yarns and yarn layers, effectively preventing the cotton yarn from becoming loose during the winding process and guaranteeing the tightness of the cotton yarn roll. An electric push rod is activated, causing an adjusting plate to move downwards. The adjusting plate then drives a limit rod to slide on the corresponding positioning rod, compressing the unused spring. This ensures the spring is in a slightly compressed or semi-compressed state before use, shortening its compression stroke. The compressed spring exerts greater damping force on the U-shaped plate, preventing the spring from weakening after prolonged use and ensuring the squeeze roller can properly compress the cotton yarn.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example

[0026] like Figure 1-5 As shown, an embodiment of this utility model discloses a winding device for cotton spinning, including a base plate 1. Two first L-shaped plates 2 are provided on the top of the base plate 1. A rotating shaft 3 is rotatably connected to one side of each first L-shaped plate 2. A U-shaped seat 4 is fixedly connected to the end of the rotating shaft 3. A winding roller 5 is threadedly connected to the two U-shaped seats 4 via multiple bolts 6. A second L-shaped plate 7 is welded to the rear side of the base plate 1. Side plates 8 are fixedly connected to both sides of the second L-shaped plate 7. Grooves 9 are provided on the side plates 8, and L-shaped blocks 10 are slidably connected to the grooves 9. The two L-shaped blocks 10... The bottom of the first L-shaped plate 7 is fixedly connected to a U-shaped plate 11. A pressing roller 12 is rotatably connected between the inner walls of both sides of the U-shaped plate 11. An electric push rod 13 is fixedly connected to the top inner wall of the second L-shaped plate 7. An adjusting plate 14 is fixedly connected to the second output end of the electric push rod 13. Multiple springs 15 are fixedly connected between the bottom of the adjusting plate 14 and the top of the U-shaped plate 11. Two positioning rods 16 are welded to the top inner wall of the second L-shaped plate 7. A limit rod 17 is slidably connected to the positioning rod 16. The end of the limit rod 17 is connected to the top of the U-shaped plate 11. With a fixed connection, the second motor 22 drives the U-shaped seat 4 to rotate via the rotating shaft 3. The U-shaped seat 4 drives the take-up roller 5 to rotate, and the cotton yarn gradually begins to wind onto the take-up roller 5. As the cotton yarn continues to wind onto the take-up roller 5, the yarn layer thickness gradually increases. Under the elastic compression of the spring 15, the squeeze roller 12 remains tightly pressed against the surface of the cotton yarn roll, applying continuous and uniform pressure to the winding cotton yarn. This ensures that the yarns and yarn layers are tightly bonded and compressed, effectively preventing the cotton yarn from becoming loose during the winding process and ensuring... To control the tightness of the cotton yarn roll, the electric push rod 13 is activated, which drives the adjusting plate 14 to move downward. The adjusting plate 14 drives the limiting rod 17 to slide on the corresponding positioning rod 16, so that the adjusting plate 14 compresses the unused spring 15. This ensures that the spring 15 is in a slightly compressed or semi-compressed state before use, shortening its compression stroke. The compressed spring 15 exerts a greater damping force on the U-shaped plate 11, thus preventing the spring 15 from weakening after prolonged use and ensuring that the squeezing roller 12 can properly compress the cotton yarn.

[0027] In some embodiments, a rectangular hole 18 is provided on the base plate 1, and a lead screw 19 is rotatably connected between the inner walls of the two sides of the rectangular hole 18.

[0028] In some embodiments, a connecting block 20 is threaded onto the lead screw 19, the bottom of one of the two first L-shaped plates 2 is fixedly connected to the top of the connecting block 20, and the bottom of the other of the two first L-shaped plates 2 is fixedly connected to the top of the base plate 1.

[0029] In some embodiments, a first motor 21 is fixedly connected to the left side of the base plate 1, and the end of the lead screw 19 extends out of the base plate 1 and is fixedly connected to the output shaft of the first motor 21. The base plate 1 serves as a support.

[0030] In some embodiments, a second motor 22 is fixedly connected to the inner wall of one side of one of the two first L-shaped plates 2, and the end of one of the two rotating shafts 3 extends out of the first L-shaped plate 2 and is fixedly connected to the output shaft of the second motor 22.

[0031] In some embodiments, four casters 23 are fixedly connected to the bottom of the base plate 1, and the outer side of the connecting block 20 is slidably connected to the inner wall of the rectangular hole 18. The casters 23 are provided to facilitate movement.

[0032] Working principle or structural principle: During use, the second motor 22 is started. The second motor 22 drives the U-shaped seat 4 to rotate via the rotating shaft 3. The U-shaped seat 4 drives the take-up roller 5 to rotate, and the cotton yarn gradually begins to wind onto the take-up roller 5. As the cotton yarn continues to wind onto the take-up roller 5, the yarn layer thickness gradually increases. Under the elastic compression of the spring 15, the squeeze roller 12 always fits tightly against the surface of the cotton yarn roll, applying continuous and uniform pressure to the winding cotton yarn, so that the yarns and yarn layers are tightly fitted and compressed, effectively preventing the cotton yarn from becoming loose during the winding process, ensuring the tightness of the cotton yarn roll. Moreover, after long-term use, when it is necessary to adjust the elasticity of the spring 15, the electric push rod 13 is started. The electric push rod 13 drives the adjusting plate 14 to move downwards, adjusting... The section plate 14 drives the limiting rod 17 to slide on the corresponding positioning rod 16, so that the adjusting plate 14 compresses the unused spring 15, so that the spring 15 is in a slightly compressed or semi-compressed state before use, shortening its compression stroke. The damping force of the compressed spring 15 on the U-shaped plate 11 is increased, thereby preventing the spring 15 from weakening after long-term use and the extrusion roller 12 from not being able to properly compress the cotton yarn. The bolt 6 facilitates quick disassembly of the take-up roller 5. At the same time, by starting the first motor 21, the first motor 21 drives the connecting block 20 to move through the lead screw 19. The connecting block 20 drives a first L-shaped plate 2 to move, so that the distance between the two first L-shaped plates 2 changes, thereby fixing take-up rollers 5 of different lengths.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
