Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a polyester-cotton yarn winding adjustment device. Background Technology

[0002] Currently, friction drive winding mechanisms are widely used in the field of polyester-cotton yarn winding. With its unique transmission method, this winding mechanism can ensure the stability of winding speed to a certain extent, making it less likely for problems such as uneven tension, yarn slack or overstretching to occur during the winding process of polyester-cotton yarn.

[0003] However, existing friction-driven winding mechanisms have a significant drawback: the winding speed is not adjustable. In actual production, due to differences in specifications and material properties between different batches of polyester-cotton yarn, or the need to adjust the winding speed according to different process requirements, existing winding mechanisms cannot meet these diverse needs, limiting production flexibility and efficiency. Therefore, there is an urgent need for a polyester-cotton yarn winding adjustment device that can adjust the winding speed. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a polyester-cotton yarn winding adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the present invention provides a polyester-cotton yarn winding adjustment device, comprising: a support, a central shaft on the support, a transmission wheel connected to a motor at one end of the central shaft, and a transmission rod at the other end, a positioning ring and an adjusting sleeve on the transmission rod, the positioning ring being fixedly connected to the transmission rod, the adjusting sleeve being a tubular part closed at one end, having a through hole at its bottom with a diameter equal to that of the transmission rod, and its inner diameter being equal to that of the positioning ring; a moving magnetic column on the inner bottom surface of the adjusting sleeve, a locking arc groove cooperating with the moving magnetic column on the end of the positioning ring adjacent to the adjusting sleeve, and a locking magnet and an unlocking magnet of opposite polarity at the bottom of the locking arc groove.

[0006] Furthermore, the transmission rod is provided with several adjusting sleeves with increasing diameters. The outer diameter of one of two adjacent adjusting sleeves is equal to the inner diameter of the other. The outer bottom surface of the adjusting sleeve is provided with a connecting arc groove coaxial with it. The moving magnetic column penetrates to the bottom of the connecting arc groove. A separating magnet with opposite polarity to the moving magnetic column is provided in the connecting arc groove.

[0007] Furthermore, the transmission rod is provided with two sets of positioning rings and adjusting sleeves mirrored at its midpoint, and positioning disks are provided at both ends of the transmission rod. The positioning disks are provided with positioning magnetic columns that cooperate with the moving magnetic columns in the connecting arc groove.

[0008] Furthermore, the positioning ring includes a middle ring and side rings fixedly disposed on both sides thereof. The middle ring has a through oblique groove on its disc surface. A T-shaped tie rod is disposed inside the middle ring, and the vertical end of the T-shaped tie rod is slidably disposed in the oblique groove. A positioning ring is disposed on the side of the side ring adjacent to the middle ring. The two positioning rings hold the T-shaped tie rod on the middle ring. The transmission rod is provided with a T-shaped groove that cooperates with the T-shaped tie rod.

[0009] Furthermore, the depth of the locking arc groove and the connecting arc groove is less than or equal to the height of the moving magnetic column protruding from the inner bottom surface of the adjusting sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model include: This invention achieves progressively adjustable winding speed through the magnetic attraction design of the adjusting sleeve and the positioning ring: when it is necessary to reduce the winding speed, the adjusting sleeve is rotated in the opposite direction so that it faces the unlocking magnet, and the adjusting sleeve is released under the action of magnetic repulsion, thereby reducing the effective transmission diameter of the transmission rod in contact with the yarn bobbin and reducing the linear speed; in addition, this device can also adapt to yarn bobbins of different lengths by adjusting the distance between the two positioning rings; while maintaining efficient winding, this device also has a high degree of adaptability and adjustability, which provides great convenience for the winding of polyester-cotton yarn.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] Reference Figure 1 This utility model provides a polyester-cotton yarn winding adjustment device, including a support 1 on which a freely rotating central shaft 2 is mounted. One end of the central shaft 2 is equipped with a transmission wheel 3 connected to the output shaft of a motor, and the other end is connected to a transmission rod 4.

[0014] The transmission rod 4 is mirrored at its midpoint with two sets of positioning rings 5 ​​and several adjusting sleeves 6. The transmission rod 4 has a T-shaped groove 401. The positioning rings 5 ​​slide along the T-shaped groove 401 and are fixed thereon. The adjusting sleeve 6 is a tubular part closed at one end. Its bottom through hole has the same diameter as the transmission rod 4. The diameters of the several adjusting sleeves 6 increase in sequence. The outer diameter of one of the adjacent adjusting sleeves 6 is equal to the inner diameter of the other. The inner diameter of the adjusting sleeve 6 adjacent to the positioning ring 5 is equal to the outer diameter of the positioning ring 5, so as to facilitate mutual cooperation.

[0015] Reference Figure 2 , Figure 3 The bottom surface of the adjusting sleeve 6 is provided with a moving magnetic column 602. The positioning ring 5 is provided with a locking arc groove 501 at the end adjacent to the adjusting sleeve 6. The bottom of the locking arc groove 501 has a locking magnet 502 and an unlocking magnet 503 with opposite polarities. The bottom surface of the adjusting sleeve 6 is provided with a connecting arc groove 601, through which the moving magnetic column 602 extends to its bottom. The connecting arc groove 601 contains a separating magnet 603 with opposite polarities, which facilitates the connection and separation between different adjusting sleeves 6. The depth of the locking arc groove 501 and the connecting arc groove 601 is less than or equal to the height of the moving magnetic column 602 protruding from the bottom surface of the adjusting sleeve 6, ensuring that the magnetic column can be effectively engaged.

[0016] Positioning disks 402 are set at both ends of the transmission rod 4. Positioning disks 402 have positioning magnetic posts 403 that cooperate with the moving magnetic posts 602 in the connecting arc groove 601; thereby fixing the idle adjusting sleeve 6 to both ends of the transmission rod 4.

[0017] To facilitate understanding of how it achieves winding speed adjustment, the working principle is explained in detail below: Several guide rollers and tension rollers are installed on the take-up frame 7. The support 1 is fixedly installed on the take-up frame 7. A yarn tube frame 9 is installed on one side of the support 1. One end of the yarn tube frame 9 holds the yarn tube 10. The yarn tube frame 9 uses a torsion spring or other existing means to bring the yarn tube 10 closer to the drive rod 4, and the polyester-cotton yarn is wound on the yarn tube 10. Figure 4 (This is for illustrative purposes only and does not represent the actual state of polyester-cotton yarn and its winding in actual applications). When the motor 8 drives the transmission rod 4, the yarn cylinder 10 is rotated through friction, and the polyester-cotton yarn is wound onto the yarn cylinder 10.

[0018] When it is necessary to increase the winding speed, the adjusting sleeve 6 is moved towards the positioning ring 5 by external force. After the adjusting sleeve 6 is placed on the positioning ring 5, the moving magnetic column 602 and the locking magnet 502 are attracted to connect the two. With the speed of the motor 8 remaining unchanged, the diameter of the transmission rod 4 is increased by the adjusting sleeve 6, thereby increasing the linear speed of the yarn cylinder 10, that is, the speed at which the yarn cylinder 10 winds the polyester-cotton yarn.

[0019] When it is necessary to reduce the winding speed, rotate the adjusting sleeve 6 in the opposite direction so that the moving magnetic column 602 is aligned with the unlocking magnet 503. Under the action of magnetic repulsion, the rotating adjusting sleeve 6 is popped off the positioning ring 5. The winding speed can be adjusted step by step by nesting or separating the several adjusting sleeves 6 set on the transmission rod 4.

[0020] In practical applications, when it is necessary to reduce the winding speed and rotate the adjusting sleeve 6, several adjusting sleeves 6 may detach at the same time. In this case, it is only necessary to separate the detached adjusting sleeves 6 from each other and then put them back on the positioning ring 5 or the adjusting sleeve 6 on it.

[0021] Reference Figure 3 The positioning ring 5 includes a middle ring 504 and side rings 505 fixedly installed on both sides of it. The middle ring 504 has an inclined groove 506 on its disc surface. A T-shaped pull rod 507 that cooperates with the T-shaped groove 401 is provided in the middle ring 504. A positioning ring 508 is provided on the side of the side ring 505 adjacent to the middle ring 504. The horizontal end of the T-shaped pull rod 507 is slidably set in the T-shaped groove 401, and the other end is slidably set in the inclined groove 506 and is held on the middle ring 504 by the positioning ring 508. The thickness of the horizontal end of the T-shaped pull rod 507 is less than the depth of the horizontal end of the T-shaped groove 401, so that it can extend and retract radially along the transmission rod 4 under the drive of the inclined groove 506 when the middle ring 504 rotates. When the horizontal end of the T-shaped pull rod 507 is away from the axis of the transmission rod 4 and abuts against the lower end face of the horizontal end of the T-shaped groove 401, the positioning ring 5 is fixed on the transmission rod 4.

[0022] The two positioning rings 5 ​​slide along the T-shaped groove 401 to adjust the distance between them, thereby accommodating yarn tubes 10 of different lengths.
