Description
Technical Field
[0001] This utility model relates to the field of cotton yarn processing technology, and in particular to a cotton yarn sliver collection device for cotton yarn processing. Background Technology
[0002] Yarn is made from cotton fibers through a spinning process. After being plied, it is called cotton thread. During the processing of cotton yarn, a cotton yarn collection device is needed to collect the cotton yarn slivers for subsequent transportation or use.
[0003] When collecting cotton yarn strips using a collecting device, one end of the cotton yarn strip is passed through a guide block that swings back and forth on the collecting device and fixed to the collecting roll. The device drives the collecting roll to rotate and collect the cotton yarn strip. During the cotton yarn processing, cotton fibers or other materials may adhere to the surface of the cotton yarn, causing the surface diameter of the cotton yarn to vary. When passing through the guide block and entering the collecting roll, the overall tightness of the cotton yarn strip changes, resulting in greater stress on a single point of the cotton yarn strip and potentially causing the cotton yarn strip to break. This affects the collecting effect of the collecting device on the cotton yarn strip. Utility Model Content
[0004] The purpose of this invention is to solve the problem that during the cotton yarn processing process, cotton lint or other particles may adhere to the surface of the cotton yarn, causing uneven diameters on different parts of the cotton yarn. This leads to changes in the overall tightness of the cotton yarn strip when passing through the guide block and entering the collection roll, resulting in excessive stress on a single point of the cotton yarn strip and potentially causing it to break. Consequently, this affects the collection effect of the collection device. Therefore, this invention proposes a cotton yarn strip collection device for cotton yarn processing.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cotton yarn sliver collection device for cotton yarn processing, comprising:
[0006] A frame is used to mount the entire collection device on one side of the cotton yarn processing equipment.
[0007] A take-up roller is mounted on one side of a frame plate via a rotating shaft to hold cotton yarn rolls. Several rubber sheets are fixed on the outer surface of the take-up roller. A servo motor is provided on one side of the frame plate, and the output end of the servo motor is fixedly connected to one end of the rotating shaft of the take-up roller via a coupling.
[0008] The bidirectional screw is mounted on the outer surface of the frame plate above the take-up roller. One end of the bidirectional screw and one end of the shaft of the take-up roller are fixedly connected to pulleys. A belt is fitted on the outside of the pulleys. The servo motor drives the take-up roller to rotate, and the bidirectional screw can be driven to rotate simultaneously through the pulleys and belt.
[0009] The guide block slides on one side of the top of the frame plate. The inner wall of the guide block is threadedly connected to the outer surface of the bidirectional screw. The bottom end of the guide block is provided with an auxiliary device that can buffer the pulling force on the cotton yarn when it moves below the guide block.
[0010] The effect achieved by the above components is as follows: When collecting processed cotton yarn using the cotton yarn collecting device, the cotton yarn roll is placed on the outer surface of the take-up roller. The position of the cotton yarn roll on the outer surface of the take-up roller is secured by the rubber sheet on the outer surface of the take-up roller. Then, one end of the cotton yarn is connected to the guide block through an auxiliary device and fixed to the cotton yarn roll by winding or bonding. Subsequently, the servo motor is operated by power control. The output end of the servo motor drives the take-up roller and the cotton yarn roll on the outer surface of the take-up roller to rotate and wind up the cotton yarn. At the same time, the belt pulley set drives the bidirectional screw to rotate, so that the guide block moves back and forth on the outer surface of the bidirectional screw, so that the cotton yarn moves back and forth and is evenly wound on the outside of the cotton yarn roll as it enters the outer surface of the cotton yarn roll.
[0011] Preferably, the auxiliary device includes two sliding rods, and the guide block has grooves on both sides. The sliding rods are located inside the grooves, and round rods are slidably connected to the inner wall of the grooves. The bottom ends of the two round rods are fixedly connected to cylinders, and springs are provided at the top ends of the round rods. The springs are located inside the grooves and their top ends are connected to the bottom ends of the sliding rods.
[0012] The effect achieved by the above components is as follows: By setting up a cylinder, when using the cotton yarn collecting device, one end of the wound cotton yarn passes through the inside of the cylinder. When the guide block moves, the cotton yarn moves back and forth through the cylinder. When the cotton yarn is uneven in surface and comes into contact with the cylinder or other equipment, causing resistance and uneven force on some parts of the cotton yarn, it will generate a downward pulling force on the cylinder. This will cause the two round rods at the top of the cylinder to slide down the inner wall of the groove and stretch the spring, allowing the cylinder to move down a certain distance. This buffers the pulling force on the cotton yarn, preventing the cotton yarn from being subjected to excessive pulling force that could cause the surface to become taut and break. When the external force disappears, the spring returns to its original state and will drive the round rods and the cylinder to move back to their original positions.
[0013] Preferably, the top two sides of the guide block are respectively fixedly connected to the first screw, one end of the inner wall of the two sliding rods slides on the outer surface of the two first screws respectively, and the top of the sliding rod is rotatably connected to a threaded ring, the inner wall of the threaded ring is threadedly connected to the outer surface of the first screw.
[0014] The effect achieved by the above components is as follows: before using the collection device, the threaded rings on the outer sides of the two first screws can be rotated on both sides of the guide block to move the threaded rings on the outer surface of the first screws to adjust the height position of the sliding rod inside the groove, change the spring compression state between the top of the round rod and the sliding rod, adjust the maximum distance the cylinder moves downward and the buffering effect on the cotton yarn.
[0015] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded ring, and the protrusions are circumferentially distributed on the outer surface of the threaded ring.
[0016] The effect achieved by the above components is that when the threaded ring is pushed to rotate, it contacts the protrusion on the outer surface of the threaded ring, making it easier to control the rotation of the threaded ring and preventing it from slipping.
[0017] Preferably, auxiliary rings are fixedly connected to both ends of the inner wall of the cylinder, and the outer edge of the inner wall of the auxiliary ring is arc-shaped.
[0018] The effect achieved by the above components is that by setting the auxiliary ring, the cotton yarn strip is less likely to be worn by the inner wall edge of the cylinder when it moves inside the cylinder.
[0019] Preferably, a positioning device is provided on one side of the shelf, the positioning device includes a T-shaped block, a plastic rod is fixedly connected to one side of the T-shaped block, a T-shaped groove is opened on one side of the shelf, the T-shaped block slides on the inner wall of the T-shaped groove, a second screw is rotatably connected to one side of the inner wall of the T-shaped groove, and the inner wall of the T-shaped block is threadedly connected to the outer surface of the second screw.
[0020] The effects achieved by the above components are as follows: When using the cotton yarn collecting device, one end of the cotton yarn entering the cotton yarn roll on the take-up roller can pass through the surface of the plastic rod. When the cotton yarn moves back and forth through the guide block, the plastic rod can further support and position the cotton yarn, improving the stability of the cotton yarn during take-up. In addition, static electricity is generated when the cotton yarn rubs against the plastic rod, which adsorbs and cleans the lint on the surface of the cotton yarn. Rotating the second screw can control the T-shaped block to move inside the T-shaped groove and adjust the horizontal position of the plastic rod.
[0021] Preferably, positioning blocks are fixedly connected to the upper and lower ends of the T-shaped block, and the end of the positioning block away from the T-shaped block slides on one side of the frame plate.
[0022] The effect achieved by the above components is that the positioning blocks on both sides of the T-shaped block abut against the outer surface of the frame plate, which can further restrict the position of the T-shaped block on one side of the frame plate and the angle between the plastic rod and the frame plate, so as to avoid the angle of the plastic rod from deviating as much as possible.
[0023] Preferably, one end of the second screw is fixedly connected to a disc, and a protruding rod is rotatably connected to one side of the disc.
[0024] The effect achieved by the above components is that holding the outer surface of the convex rod makes it easier to push the disc to control the rotation of the second screw and adjust the position of the T-block.
[0025] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0026] In this invention, by setting an auxiliary device, when winding the cotton yarn, the cotton yarn passes through the inside of the cylinder. When the cotton yarn is pulled, the round rod slides on the inner wall of the groove and stretches the spring, so that the cylinder can move downward a certain distance following the force of the cotton yarn, thus buffering the force on the cotton yarn and avoiding the cotton yarn from becoming too tight and breaking as much as possible, thereby improving the stability of the collecting device during use.

[0032] Example 1, such as Figure 1-2As shown, a cotton yarn sliver collection device for cotton yarn processing includes a frame plate 1, which is used to install the collection device as a whole on one side of a cotton yarn processing equipment. A take-up roller 5 is installed on one side of the frame plate 1 via a rotating shaft to hold cotton yarn rolls. Several rubber sheets are fixed on the outer surface of the take-up roller 5. A servo motor 4 is provided on one side of the frame plate 1. The output end of the servo motor 4 is fixedly connected to one end of the rotating shaft of the take-up roller 5 via a coupling. A bidirectional screw 6 is installed on the outer surface of the frame plate 1 above the take-up roller 5. A pulley is fixedly connected to one end of the bidirectional screw 6 and one end of the rotating shaft of the take-up roller 5. A belt is sleeved on the outer side of the pulley. The operation of the servo motor 4 drives the take-up roller 5 to rotate, and the bidirectional screw 6 can be driven to rotate simultaneously through the pulley and belt transmission. A guide block 7 slides on one side of the top of the frame plate 1. The inner wall of the guide block 7 is threadedly connected to the outer surface of the bidirectional screw 6. A movable guide block 7 is provided at the bottom end. An auxiliary device 2 is used to buffer the tensile force experienced by the cotton yarn sliver when it moves below the guide block 7. When collecting the processed cotton yarn sliver using a cotton yarn sliver collecting device, the cotton yarn sliver roll is placed on the outer surface of the take-up roller 5. The position of the cotton yarn sliver roll on the outer surface of the take-up roller 5 is secured by the rubber sheet on the outer surface of the take-up roller 5. Then, one end of the cotton yarn sliver is connected to the guide block 7 through the auxiliary device 2 and then fixed to the cotton yarn roll by winding or bonding. Subsequently, the servo motor 4 is operated by power control. The output end of the servo motor 4 drives the take-up roller 5 and the cotton yarn roll on the outer surface of the take-up roller 5 to rotate and wind the cotton yarn sliver. At the same time, the double-direction screw 6 is driven to rotate through the belt and pulley set, so that the guide block 7 moves back and forth on the outer surface of the double-direction screw 6, so that the cotton yarn sliver moves back and forth and is evenly wound on the outside of the cotton yarn roll as it enters the outer surface of the cotton yarn roll.
[0033] Reference Figure 1-3As shown in this embodiment: the auxiliary device 2 includes two sliding rods 22, and the guide block 7 has grooves 21 on both sides. The sliding rods 22 are located inside the grooves 21. The inner wall of the grooves 21 is slidably connected to round rods 24. The bottom ends of the two round rods 24 are fixedly connected to cylinders 25. The top ends of the round rods 24 are provided with springs 23. The springs 23 are located inside the grooves 21 and their top ends are connected to the bottom ends of the sliding rods 22. By setting the cylinders 25, when using the cotton yarn collecting device, one end of the wound cotton yarn passes through the inside of the cylinders 25. When the guide block 7 moves, the cotton yarn moves back and forth through the cylinders 25. When the cotton yarn is uneven in surface and comes into contact with the cylinders 25 or other equipment, causing resistance and uneven force on some parts of the cotton yarn, it will generate a downward pulling force on the cylinders 25, causing the top end of the cylinders 25 to... The two round rods 24 slide downwards on the inner wall of the groove 21 and stretch the spring 23, allowing the cylinder 25 to move downwards a certain distance. This buffers the tension on the cotton yarn, preventing it from being stretched too much and breaking. When the external force disappears, the spring 23 returns to its original state, causing the round rods 24 and the cylinder 25 to move back to their original positions. By setting the auxiliary device 2, when winding the cotton yarn, the cotton yarn passes through the inside of the cylinder 25. When the cotton yarn is stretched, the round rods 24 slide on the inner wall of the groove 21 and stretch the spring 23, allowing the cylinder 25 to move downwards a certain distance following the force on the cotton yarn. This buffers the force on the cotton yarn, minimizing the possibility of it breaking due to excessive tension and improving the stability of the collecting device during use.
[0034] Reference Figure 2-3 As shown in this embodiment: First screws 26 are fixedly connected to both sides of the top of the guide block 7. One end of the inner wall of each of the two sliding rods 22 slides on the outer surface of the two first screws 26. A threaded ring 27 is rotatably connected to the top of each sliding rod 22. The inner wall of the threaded ring 27 is threadedly connected to the outer surface of the first screw 26. Before using the collecting device, the threaded rings 27 on the outer sides of the two first screws 26 can be rotated on both sides of the guide block 7 to move the threaded rings 27 on the outer surface of the first screws 26, adjusting the height position of the sliding rods 22 inside the groove 21, and changing the spring 23 between the top of the round rod 24 and the sliding rod 22. In the compressed state, the maximum downward movement distance of the cylinder 25 and the buffering effect on the cotton yarn are adjusted. Several protrusions 28 are fixedly connected to the outer surface of the threaded ring 27. The protrusions 28 are circumferentially distributed on the outer surface of the threaded ring 27. When the threaded ring 27 is pushed to rotate, it contacts the protrusions 28 on the outer surface of the threaded ring 27, which makes it easier to control the rotation of the threaded ring 27 and prevents it from slipping. Auxiliary rings 29 are fixedly connected to both ends of the inner wall of the cylinder 25. The outer edge of the inner wall of the auxiliary ring 29 is arc-shaped. By setting the auxiliary rings 29, the cotton yarn is less likely to be worn by the inner wall edge of the cylinder 25 when it enters the cylinder 25 and moves inside.
[0035] Reference Figure 1 , Figure 2 and Figure 4 As shown in this embodiment: a positioning device 3 is provided on one side of the frame plate 1. The positioning device 3 includes a T-shaped block 33. A plastic rod 34 is fixedly connected to one side of the T-shaped block 33. A T-shaped groove 31 is opened on one side of the frame plate 1. The T-shaped block 33 slides on the inner wall of the T-shaped groove 31. A second screw 32 is rotatably connected to one side of the inner wall of the T-shaped groove 31. The inner wall of the T-shaped block 33 is threadedly connected to the outer surface of the second screw 32. When using the cotton yarn collecting device, one end of the cotton yarn entering the cotton yarn roll on the take-up roller 5 can pass through the surface of the plastic rod 34. When the cotton yarn moves back and forth driven by the guide block 7, the plastic rod 34 can further support and position the cotton yarn, improving the stability of the cotton yarn during take-up. When the cotton yarn rubs against the plastic rod 34, static electricity is generated, which adsorbs and cleans the lint on the surface of the cotton yarn. Rotating the second screw 32 can control the movement of the T-shaped block 33 inside the T-shaped groove 31 to adjust the horizontal position of the plastic rod 34.
[0036] Reference Figure 2 and Figure 4 As shown in this embodiment: positioning blocks 35 are fixedly connected to the upper and lower ends of the T-shaped block 33 respectively. The end of the positioning block 35 away from the T-shaped block 33 slides on one side of the frame plate 1. The positioning blocks 35 on both sides of the T-shaped block 33 abut against the outer surface of the frame plate 1, which can further restrict the position of the T-shaped block 33 on one side of the frame plate 1 and the angle between the plastic rod 34 and the frame plate 1, so as to avoid the angle of the plastic rod 34 from deflecting as much as possible. One end of the second screw 32 is fixedly connected to the disc 36. A protruding rod 37 is rotatably connected to one side of the disc 36. Holding the outer surface of the protruding rod 37 can more conveniently push the disc 36 to control the rotation of the second screw 32 to adjust the position of the T-shaped block 33.
[0037] Working principle: When collecting processed cotton yarn using the cotton yarn collecting device, the cotton yarn roll is placed on the outer surface of the take-up roller 5. The rubber sheet on the outer surface of the take-up roller 5 secures the cotton yarn roll to the outer surface of the take-up roller 5. Then, one end of the cotton yarn is passed through the inside of the cylinder 25. Rotating the second screw 32 controls the movement of the T-block 33 inside the T-groove 31 to adjust the horizontal position of the plastic rod 34, so that the cotton yarn passes over the surface of the plastic rod 34 and is fixed to the cotton yarn roll by winding or bonding. Then, the servo motor 4 is operated by power control. The output end of the servo motor 4 drives the take-up roller 5 and the cotton yarn roll on the outer surface of the take-up roller 5 to rotate and wind up the cotton yarn. The belt pulley set works in conjunction with the double... Rotating the screw 6 causes the guide block 7 to move back and forth on the outer surface of the bidirectional screw 6, driving the cotton yarn to move back and forth evenly around the outer side of the cotton yarn roll as it enters the outer surface of the cotton yarn roll. When the cotton yarn experiences resistance due to uneven surface and contact with the cylinder 25 or other equipment, resulting in uneven force on some parts of the cotton yarn, it will generate a downward pulling force on the cylinder 25. This causes the two round rods 24 at the top of the cylinder 25 to slide downward on the inner wall of the slide groove 21 and stretch the spring 23, allowing the cylinder 25 to move downward a certain distance. This buffers the pulling force on the cotton yarn, preventing the cotton yarn from being subjected to excessive pulling force that could cause the surface to become taut and break. When the external force disappears, the spring 23 returns to its original state, driving the round rods 24 and the cylinder 25 to move back to their original positions.
