Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing machine technology, and in particular to a convenient disassembly drum for printing and dyeing machines. Background Technology

[0002] In the textile industry, dyeing and printing is an important part of the textile industry. Its processing includes multiple steps such as pretreatment, dyeing, printing, finishing and washing, aiming to give fabrics rich colors and unique properties. In the dyeing and printing process, the dyeing and printing machine is the core equipment, and the drum is the key component of the dyeing and printing machine to realize the dyeing and printing and conveying of the fabric. The drum is an important part of the dyeing and printing machine, used to carry the fabric and realize the rotation and conveying of the fabric during the dyeing and printing process.

[0003] In existing technologies, the connection between the rotor and the main body of traditional dyeing and printing machines is relatively complex, typically requiring multiple bolts for fixation. Disassembly necessitates the use of tools to unscrew each bolt individually, a cumbersome and time-consuming process. This presents several shortcomings in practical use. For example, over long-term use, wear and dirt accumulation between the rotor and the main body can cause bolt wear or oil buildup, potentially leading to stripping or slippage during disassembly, making the process even more difficult. Furthermore, when the rotor wears out, malfunctions, or needs to be replaced with a different size to meet varying dyeing and printing requirements, the difficulty in disassembly prevents quick replacement, resulting in prolonged machine downtime, impacting production schedules, and further increasing production costs. Therefore, designing a rotor that allows for rapid installation and disassembly while ensuring that the fixing connections remain unaffected and uninterrupted after extended use is a key challenge in dyeing and printing machine rotor technology.

[0027] like Figure 1-4As shown, it includes: two fixed seats 1, each with a pressure plate 11 inserted into its upper end; a rotating cylinder 28 rotatably connected between the middle of the two fixed seats 1 and the pressure plate 11; guide grooves 12 and slots 13 are respectively opened on both sides of the middle of the upper end of the two fixed seats 1; guide rods 14 and insert rods 15 are fixedly installed on both sides of the middle of the lower end of the two pressure plates 11, and the guide rods 14 and insert rods 15 are respectively inserted into the guide grooves 12 and slots 13; a base plate 16 is fixedly installed on the lower end of the insert rod 15; a movable groove 17 is opened on one side of the middle of the two fixed seats 1; a sliding groove 18 is opened through one end of the movable groove 17; the movable groove 17... Springs 21 are fixedly connected to both sides of the middle of the other end of the movable groove 17. A slider 19 is fixedly installed on one end of each spring 21. A convex groove 20 is opened in the middle of the slider 19. A pressure rod 22 is fixedly connected to one end of the slider 19. The slider 19 is located at the upper end of the base plate 16. The width of the side with the smaller opening of the convex groove 20 is smaller than the diameter of the base plate 16. The diameter of the side with the smaller opening of the convex groove 20 is slightly larger than the diameter of the insertion rod 15. The diameter of the side with the larger opening of the convex groove 20 is slightly larger than the diameter of the base plate 16. The slider 19 is slidably engaged with the middle of the movable groove 17. The pressure rod 22 is slidably engaged with the middle of the sliding groove 18.

[0028] In this embodiment, when disassembling the rotating cylinder 28 as needed, two people simultaneously press the pressure rods 22 on the sides of the two fixed seats 1 to squeeze inward. During this process, the two sets of springs 21 will be compressed, causing the slider 19 to move in the direction of the compression of the springs 21. When the slider 19 moves, the side with the smaller opening of the convex groove 20 will also move accordingly. As the user continues to press the pressure rods 22, the side with the larger opening of the convex groove 20 inside the slider 19 will eventually move to the top of the base plate 16. At this time, the slider 19 will release the restriction on the base plate 16 below the insertion rod 15, and thus release the restriction on the entire pressure plate 11. The pressure plate 11 can be removed by the handle 31, and then the rotating cylinder 28 can be removed for replacement. When installing the rotating cylinder 28, first, the two ends of the rotating cylinder 28 are inserted into the semi-circular rotating grooves 27 opened in the two fixed seats 1, and then the two The guide rod 14 and the insert rod 15 below the pressure plate 11 are aligned with the guide groove 12 and the slot 13 respectively and inserted and pressed down. Due to the presence of the slider 19, the pressure plate 11 cannot touch the bottom. The user presses the pressure rod 22 to move the side with the smaller opening of the convex groove 20 inside the slider 19 inward, so that the side with the larger opening of the convex groove 20 moves directly below the base plate 16, and the pressure plate 11 touches the bottom. Then, the user releases the limit on the pressure rod 22, and the slider 19 will return to its original position under the action of the spring 21. The side with the smaller opening of the convex groove 20 inside will move to the top of the base plate 16, thereby limiting the entire pressure plate 11 and the rotating cylinder 28. Through the sliding and locking structure composed of the slider 19, the convex groove 20, the pressure rod 22, the spring 21 and other components, together with the base plate 16 of the insert rod 15, the rapid locking and unlocking of the rotating cylinder 28 is achieved. Example

[0029] like Figure 1-3 As shown, a semi-circular groove 27 is provided on one side of the middle of the two sets of fixed seats 1 and pressure plates 11. A complete rotation space is formed between the two semi-circular grooves 27 on one side. Both ends of the rotating cylinder 28 are fixedly connected to rotating rings 29. The two rotating rings 29 are respectively rotated and engaged with the two sets of semi-circular grooves 27. A cross slot 30 is provided in the middle of one of the rotating rings 29.

A support plate 24 is fixedly installed at one end of one of the fixed seats 1. The material of the support plate 24 has high strength and stability, which can provide reliable support for the motor 25 and ensure that the motor 25 will not loosen during operation. A cross plug 26 is fixedly connected to the output end of the motor 25. The shape of the cross plug 26 matches the shape of the cross slot 30 and can be spliced ​​to transmit the torque of the motor 25.

[0031] Working principle:

[0032] like Figure 1-4As shown, when disassembling the rotating cylinder 28, two people simultaneously press the pressure rods 22 on the sides of the two fixed seats 1 to squeeze inward. During this process, the two sets of springs 21 will be compressed, causing the slider 19 to move in the direction of the compression of the springs 21. When the slider 19 moves, the side with the smaller opening of the convex groove 20 will also move accordingly. As the user continues to press the pressure rods 22, the side with the larger opening of the convex groove 20 inside the slider 19 will eventually move to the top of the base plate 16. At this time, the slider 19 will release the restriction on the base plate 16 below the insertion rod 15, and thus release the restriction on the entire pressure plate 11. The pressure plate 11 can be removed by the handle 31, and then the rotating cylinder 28 can be removed for replacement. When installing the rotating cylinder 28, first, the two ends of the rotating cylinder 28 are inserted into the semi-circular rotating grooves 27 opened in the two fixed seats 1, and then the two pressure plates 11 are installed. The guide rod 14 and the insert rod 15 below are aligned with the guide groove 12 and the slot 13 respectively and inserted and pressed down. Due to the presence of the slider 19, the pressure plate 11 cannot touch the bottom. The user presses the pressure rod 22 to move the side with the smaller opening of the convex groove 20 inside the slider 19 inward, so that the side with the larger opening of the convex groove 20 moves directly below the base plate 16, and the pressure plate 11 touches the bottom. Then, the user releases the limit on the pressure rod 22, and the slider 19 will return to its original position under the action of the spring 21. The side with the smaller opening of the convex groove 20 inside will move to the top of the base plate 16, thereby limiting the entire pressure plate 11 and the rotating cylinder 28. Through the sliding and locking structure composed of the slider 19, the convex groove 20, the pressure rod 22, the spring 21 and other components, together with the base plate 16 of the insert rod 15, the rapid locking and unlocking of the rotating cylinder 28 is achieved.
