Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester-cotton yarn winding technology, specifically an automatic winding machine for polyester-cotton yarn. Background Technology
[0002] Polyester-cotton blended yarn possesses advantages such as high breaking strength, low shrinkage, and good heat resistance, and is widely used in chemical fiber fabrics and wrinkle-resistant high-grade cotton fabrics. When winding polyester-cotton yarn, a winding drum is required. However, different equipment requires winding drums of different diameters during the weaving process, necessitating the use of different diameter drums when winding the yarn. Existing automatic winding machines use adjustable extrusion plates to press and fix the inner hole of the winding drum when installing drums of different diameters. However, this installation method mainly uses relatively large extrusion pressure to locally compress the inner hole of the winding drum. Furthermore, most existing winding drums are made of plastic, which can cause overall deformation and localized bulging when subjected to large local extrusion pressure. This leads to yarn displacement during winding, resulting in uneven yarn winding and affecting subsequent weaving and yarn arrangement. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding machine for polyester-cotton yarn, comprising a support base and a rotating column, wherein the top of the rotating column is provided with a drive shaft that can only move along the axis of the rotating column, a fixed ring is fixedly connected in the middle of the rotating column, an adjusting ring is threadedly connected to the side end of the rotating column, and a guide plate is provided between the adjusting ring and the fixed ring.

Detailed Implementation
[0023] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: an automatic winding machine for polyester-cotton yarn, including a support base 1 and a rotating column 3. The top of the rotating column 3 is equipped with a drive shaft 2 that can only move along the axis of the rotating column 3. A motor is located on the side of the support base 1, and the drive shaft moves horizontally with the motor. A fixing ring 4 is fixedly connected to the middle of the rotating column 3. An adjusting ring 10 is threadedly connected to the side end of the rotating column 3. A guide plate 8 is provided between the adjusting ring 10 and the fixing ring 4. A moving plate 11 is slidably connected to the side end of the adjusting ring 10, and the moving plate 11 can be controlled to move along the axis of the rotating column 3. The fixing ring 4… Its outer wall surface is provided with a guide groove 5 that can control the reciprocating motion of the rotating column 3 along the axis of the drive shaft 2, and a sliding groove 6 and a guide plate 8 are provided on the side away from the support base 1. An L-shaped mounting plate 9 is fixedly connected to the side of the guide plate 8 near the rotating column 3, and a fixing rubber ring 18 is inserted into the side away from the rotation. The fixing rubber ring 18 is used to limit and fix the winding cylinder of the yarn winding. An auxiliary plate 13 is inserted in the middle of the mounting plate 9. The lower end of the auxiliary plate 13 is hinged to a linkage rod 15 that can control the guide plate 8 to approach or move away from the rotating column 3. The lower end of the linkage rod 15 is hinged to the moving plate 11.
[0025] The adjusting ring 10 has a T-shaped auxiliary groove on the side near the moving plate 11. The moving plate 11 has an L-shaped structure at the end near the adjusting ring, and a T-shaped connecting part is fixedly connected to the top of the moving plate 11. The connecting part is slidably connected in the auxiliary groove. The side end of the rotating column 3 has multiple placement grooves 12, which are arranged along the axis of the rotating column 3. The moving plate 11 is inserted into the placement groove 12. When winding cylinders of different diameters are placed on the guide plate 8, the adjusting ring 10 can be rotated to drive the moving plate 11 to move in the placement groove 12, and the direction of movement is along the axis of the rotating column 3.
[0026] The sliding groove 6 has a T-shaped structure. The auxiliary plate 13 has a T-shaped structure at one end near the fixing ring 4, and the top end is slidably connected in the sliding groove 6. The auxiliary plate 13 has an L-shaped structure at the other end away from the fixing ring 4, and the top end is provided with an installation port 14. The installation plate 9 is inserted into the installation port 14. When the moving plate 11 moves, the moving plate 11 drives the auxiliary plate 13 to move through the linkage rod 15. However, the direction of movement of the auxiliary plate 13 is restricted by the sliding groove 6, so that the moving plate 11 can only move in the vertical direction. This ensures that the contact area between the guide plate 8 and the fixing rubber ring 18 and the inner wall of the winding cylinder will not change, thus preventing the winding cylinder from deforming due to excessive pressure concentration inside when it is fixed.
[0027] The guide groove 5 has a wave-like structure and is arranged around the fixing ring 4. The support base 1 has an L-shaped structure and a fixing column 7 is fixedly connected to the support base 1. The upper end of the fixing column 7 is inlaid with a ball, and the side end of the ball is located in the guide groove 5. When the drive shaft 2 drives the rotating column 3 to rotate, the ball rolls in the guide groove 5, thereby controlling the fixing ring 4 and the rotating column 3 to move along the axis of the drive shaft 2, so that the polyester-cotton yarn can be evenly wound on the winding drum, avoiding the polyester-cotton yarn from concentrating in a certain part during winding.
[0028] The end of the guide plate 8 away from the fixing ring 4 is arc-shaped, and the end of the guide plate 8 near the fixing ring 4 is horizontal. A connecting groove 16 is provided in this part. The inner ring of the fixing rubber ring 18 is fixedly connected to a connecting protrusion 17, which engages with the connecting groove 16. The left side of the outer ring of the fixing rubber ring 18 is arc-shaped, and the right side of the outer ring of the fixing rubber ring 18 is provided with multiple friction protrusions. When the winding drum is installed on the guide plate 8, the guide plate 8 can guide the installation of the winding drum and limit and fix it by the friction between the fixing rubber ring 18 and the inner wall of the winding drum, reducing the squeezing force on the winding drum and preventing the winding drum from moving when winding the yarn.
[0029] Although embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the usage of the embodiments of the present invention, and is not intended to limit the present invention in any way. Those skilled in the art will understand that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
