Description

Technical Field

[0001] This utility model relates to the technical field of yarn winding equipment, specifically to a polyester-cotton blended yarn winding equipment. Background Technology

[0002] In the textile industry, polyester-cotton blended yarns are widely used in the production of various textiles due to their combination of the excellent properties of polyester and cotton fibers. Winding is a crucial step in the production of polyester-cotton blended yarns, and its quality directly affects the efficiency of subsequent textile processing and the quality of the finished product. During the winding process, the diameter of the take-up roller gradually increases from the inside to the outside (e.g., from an empty tube to a full roll). If the drive motor speed is constant, the yarn linear speed will increase with the increase in the roll diameter, leading to a gradual increase in tension. Without tension adjustment, loosening or breakage can easily occur. Summary of the Invention

[0003] The purpose of this invention is to provide a device for winding polyester-cotton blended yarns to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a polyester-cotton blended yarn winding device, comprising a frame, a slide groove on the side of the frame, a compression spring fixedly installed at the bottom of the slide groove, and a slider fixedly connected to the other end of the compression spring, the slider being slidably disposed within the slide groove, a clamping assembly fixedly connected to the side of the slider, a transmission rod rotatably mounted at the bottom of the slider, a moving block rotatably mounted at the bottom of the transmission rod, a chuck slidably disposed on the side of the moving block and fixedly connected to the side of the frame, a limiting clamp fixedly installed at the bottom of the moving block, a synchronization ring engaging on the side of the limiting clamp, a driver fixedly mounted on the side of the frame, and a first conical block fixedly mounted on the side of the driver.

[0005] Preferably, a first rotating disk is fixedly mounted on the side of the frame, a winding roller is connected to the side of the first rotating disk by a pin, and a second rotating disk is connected to the end of the winding roller away from the first rotating disk by a rotating shaft.

[0006] Preferably, the side of the first rotating disk is synchronously connected to a second conical block via a rotating shaft, and the second conical block is configured to cooperate with a fixed ring, and the winding roller is configured to slide in contact with the pressing assembly.

[0007] Preferably, the clamping assembly includes a support rod, which is fixedly connected to the side of the slider. The bottom of the support rod is connected to a clamping plate via a straight rod, and the clamping plate slides in contact with the winding roller.

[0008] Preferably, a lead screw is rotatably mounted on the side of the frame, the shaft of the lead screw is rotatably located inside the frame, and a guide block is slidably mounted on the side of the lead screw.

[0009] Preferably, a synchronous belt is installed on the side of the lead screw, and the lead screw is connected to the shaft of the second rotating disk via the synchronous belt.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by pressing the polyester-cotton blended yarn on the side of the winding roller with the pressing component, the yarn is made more compact on the side of the winding roller, improving the uniformity and tightness of the winding. In addition, the pressing component can convert the diameter change caused by the winding of the yarn into a change in the relative position of the first conical block and the synchronization ring through the connecting rod component, thereby realizing the adjustment of the rotation speed of the winding roller, ensuring that the tension of the yarn is constant during the winding process, effectively avoiding the situation where the yarn linear speed increases with the increase of the winding diameter, which leads to the gradual increase of tension and yarn breakage, and effectively improving the winding quality of polyester-cotton blended yarn.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1-4This utility model provides a technical solution: a polyester-cotton blended yarn winding device, including a frame 1, a groove 2 on the side of the frame 1, a compression spring 3 fixedly installed at the bottom of the groove 2, and a slider 4 fixedly connected to the other end of the compression spring 3. The slider 4 is slidably disposed in the groove 2. A pressing assembly is fixedly connected to the side of the slider 4. The pressing assembly includes a support rod 16, which is fixedly connected to the side of the slider 4. A pressing plate 17 is connected to the bottom of the support rod 16 through a straight rod. The pressing plate 17 contacts and slides with the winding roller 13. The compression spring 3 pulls the slider 4 to slide in the groove 2. The slider 4 drives the pressing plate 17 to move synchronously through the support rod 16, so that the pressing plate 17 compacts the polyester-cotton blended yarn on the side of the winding roller 13, making the yarn more compact on the side of the winding roller 13, and improving the uniformity and tightness of the winding.

[0018] A transmission rod 5 is rotatably mounted on the bottom of slider 4, and a moving block 6 is rotatably mounted on the bottom of transmission rod 5. A chuck 7 is slidably mounted on the side of moving block 6 and is fixedly connected to the side of frame 1. A limiting clamp 8 is fixedly mounted on the bottom of moving block 6, and a synchronization ring 9 is clamped on the side of limiting clamp 8. A driver 10 is fixedly mounted on the side of frame 1, and a first conical block 11 is fixedly mounted on the side of driver 10. The displacement generated by slider 4 sliding in the slide groove 2 will pull moving block 6 through transmission rod 5, which will be converted into a position change of moving block 6 in chuck 7. At the same time, the limiting clamp 8 at the bottom of moving block 6 will drive the synchronization ring 9 to change the relative position of the first conical block 11, thereby realizing the adjustment of the rotation speed of winding roller 13, ensuring that the yarn tension is constant during winding, and effectively avoiding the yarn speed from increasing with the increase of winding diameter, which would lead to a gradual increase in tension and yarn breakage.

[0019] A first rotating disk 12 is fixedly installed on the side of the frame 1. A winding roller 13 is connected to the side of the first rotating disk 12 via a pin. A second rotating disk 14 is connected to the end of the winding roller 13 away from the first rotating disk 12 via a rotating shaft. A second conical block 15 is synchronously connected to the side of the first rotating disk 12 via a rotating shaft. The second conical block 15 is configured to cooperate with a fixing ring. The winding roller 13 is slidably connected to the pressing assembly. The first conical block 11 and the second conical block 15 are synchronously rotated and connected via a synchronous ring 9. When the synchronous ring 9 is in different positions, the transmission ratio of the first conical block 11 and the second conical block 15 is different, thereby controlling the rotation speed of the second conical block 15 and the first rotating disk 12. This enables flexible and precise adjustment of the winding speed, which can meet the winding requirements of polyester-cotton blended yarns of different specifications and processes, thus improving the applicability of the equipment.

[0020] A lead screw 18 is rotatably mounted on the side of the frame 1. The shaft of the lead screw 18 is rotatably located inside the frame 1. A guide block 19 is slidably mounted on the side of the lead screw 18. A synchronous belt 20 is mounted on the side of the lead screw 18. The lead screw 18 is connected to the shaft of the second rotating disk 14 via the synchronous belt 20.

[0021] In use, when the winding roller 13 is working, the polyester-cotton blended yarn is evenly wound onto the yarn bobbin on the side of the winding roller 13 under the action of the yarn guide. At this time, the compression spring 3 pulls the slider 4 to slide in the groove 2. The slider 4 drives the pressing plate 17 to move synchronously through the support rod 16, so that the pressing plate 17 compacts the polyester-cotton blended yarn on the side of the winding roller 13, making the yarn more compact on the side of the winding roller 13, improving the uniformity and tightness of the winding. As the diameter of the yarn bobbin increases, the pressing plate 17, through the support rod 16, drives the slider 4 to move... The sliding block 4 slides within the groove 2, and the displacement generated by the sliding block 4 within the groove 2 will pull the moving block 6 through the transmission rod 5, which will be converted into a positional change of the moving block 6 within the chuck 7. At the same time, the limiting clamp 8 at the bottom of the moving block 6 will drive the synchronous ring 9 to change the relative position of the first conical block 11. When the synchronous ring 9 is in different positions, the transmission ratio between the first conical block 11 and the second conical block 15 is different, thereby controlling the rotational speed of the second conical block 15 and the first rotating disk 12, achieving automatic control of the rotational speed of the winding roller 13. This effectively avoids the yarn linear speed from increasing with the increase of the winding diameter, which would lead to a gradual increase in tension and yarn breakage, and effectively improves the winding quality of polyester-cotton blended yarn.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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.
