Description

Technical Field

[0001] This application relates to the field of carding machine technology, and in particular to a multi-cavity diversion device for a middle doff carding machine. Background Technology

[0002] The middle doffer is a core component of the carding machine in textile machinery. It is a small roller structure. The middle doffer increases the carding points and carding surface of the carding machine. Its function is to cohede the fibers on the cylinder surface into a fiber layer and achieve carding and uniform mixing in the process. The middle doffer and the cylinder together form a double roller system, which is made of welded steel plate or cast iron. Both ends are connected to the shaft through plugs. It has extremely high requirements for roundness, concentricity and dynamic balance.

[0003] In the existing technology, the multi-cavity diversion device of the traditional carding machine is mostly a single channel or a simple dual-channel design. During diversion, uneven fiber distribution is prone to occur, resulting in large differences in the degree of fiber carding in different areas. This leads to insufficient fiber mixing and reduces the uniformity and quality of the fiber web.

[0004] Therefore, we propose a multi-cavity diversion device for a mid-doff carding machine to solve the above problems. Utility Model Content

[0012] A further feature of this application is that a lower transfer and diversion roller arc plate is fixedly installed inside the U-shaped frame, and the lower transfer and diversion roller arc plate is located above the lower transfer and diversion roller.

[0021] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a multi-cavity diversion device for a carding machine, including a U-shaped frame 1 installed and fixed inside the carding machine and located between the main cylinder and the chest cylinder, and an intermediate doffer 3 disposed on the U-shaped frame 1. A rotating shaft 2 is rotatably installed inside the U-shaped frame 1, and the intermediate doffer 3 is fixedly sleeved on the rotating shaft 2. The intermediate doffer 3 is close to the chest cylinder. A rotating shaft 4 and a rotating shaft 5 are rotatably installed inside the U-shaped frame 1. The rotating shaft 4 is located to the upper left of the intermediate doffer 3, and the rotating shaft 5 is located to the lower left of the intermediate doffer 3. A plurality of upper transfer diversion rollers 6 are fixedly sleeved on the rotating shaft 4 and arranged at equal intervals. A plurality of lower transfer diversion rollers 6 are fixedly sleeved on the rotating shaft 5 and arranged at equal intervals. The upper and lower transfer diverting rollers 7 are arranged in an alternating pattern, with both upper and lower transfer diverting rollers 6 and 7 close to the main cylinder. By setting a central doffer 3, and cooperating with multiple upper transfer diverting rollers 6 on the upper left and multiple lower transfer diverting rollers 7 on the lower left, the fibers conveyed by the chest cylinder can be precisely diverted. The multiple equally spaced upper transfer diverting rollers 6 and multiple equally spaced lower transfer diverting rollers 7 can divide the fibers into different "cavity channels". The fibers that have passed through different transfer diverting rollers can be more fully mixed together on the main cylinder, making the fiber combing more thorough and helping to improve the uniformity and quality of the final fiber web.

[0023] In this embodiment, both the front and rear ends of the rotating shaft 2 extend outside the U-shaped frame 1. A drive gear 21 is fixedly installed at the front end of the rotating shaft 2. A transmission assembly 1 and a transmission assembly 2 are provided on the front side of the U-shaped frame 1. The transmission assembly 1 is used to control the rotation of the rotating shaft 2 4, and the transmission assembly 2 is used to control the rotation of the rotating shaft 3 5. The transmission assembly 1 includes an upper transmission shaft 8, a driven gear 9, a main pulley 10, a secondary pulley 11, and a belt 12. The upper transmission shaft 8 is rotatably installed on the front of the U-shaped frame 1. On the outer side wall, driven gear 9 and main pulley 10 are both fixedly sleeved on the upper drive shaft 8. Driven gear 9 meshes with drive gear 21. The front end of rotating shaft 4 extends to the outside of U-shaped frame 1. Auxiliary pulley 11 is fixedly sleeved on the front end of rotating shaft 4. Belt 12 is tensioned and sleeved on main pulley 10 and auxiliary pulley 11. The drive is transmitted through the meshing of driven gear 9 and drive gear 21, and in conjunction with main pulley 10, auxiliary pulley 11 and belt 12. The transmission mechanism 12 controls the simultaneous rotation of shaft 2 (4) and shaft 2 (2), ensuring that the direction of rotation of shaft 2 (4) is opposite to that of shaft 2 (2). The transmission assembly 2 includes a lower transmission shaft 13, a driven gear 14, a main pulley 15, a secondary pulley 16, and a belt 17. The lower transmission shaft 13 is rotatably mounted on the front outer wall of the U-shaped frame 1. Both the driven gear 14 and the main pulley 15 are fixedly mounted on the lower transmission shaft 13. The driven gear 14 and the driving gear 21 are in contact with each other. The front end of the rotating shaft 3 5 extends to the outside of the U-shaped frame 1. The auxiliary pulley 2 16 is fixedly sleeved on the front end of the rotating shaft 3 5. The belt 2 17 is tensioned and sleeved on the main pulley 2 15 and the auxiliary pulley 2 16. By utilizing the meshing transmission action of the driven gear 2 14 and the driving gear 21, and in conjunction with the transmission action of the main pulley 2 15, the auxiliary pulley 2 16 and the belt 2 17, the rotating shaft 3 5 and the rotating shaft 1 2 can be controlled to rotate simultaneously, and the direction of rotation of the rotating shaft 3 5 is opposite to that of the rotating shaft 1 2.

[0024] In this embodiment, the multiple upper transfer diverting rollers 6 are configured with the same shape and size, and the multiple lower transfer diverting rollers 7 are configured with the same shape and size. The vertical distance between two adjacent upper transfer diverting rollers 6 is greater than the length of the lower transfer diverting roller 7, which can ensure that the fibers on the cylinder are completely and thoroughly diverted.

[0025] In this embodiment, driven gear 19 and driven gear 214 are set to have the same diameter to ensure that rotating shaft 24 and rotating shaft 35 rotate at the same speed, thereby making the upper transfer diverting roller 6 and the lower transfer diverting roller 7 rotate at the same speed.

[0026] In this embodiment, an upper transfer diverter roller arc plate 18 is fixedly installed inside the U-shaped frame 1. The upper transfer diverter roller arc plate 18 is located above the upper transfer diverter roller 6. The design of the upper transfer diverter roller arc plate 18 can stabilize the airflow during fiber transfer, guide the fiber to adhere to the roller surface of the upper transfer diverter roller 6, reduce fly waste, and improve fiber transfer efficiency.

[0027] In this embodiment, a lower transfer diverter roller arc plate 19 is fixedly installed inside the U-shaped frame 1. The lower transfer diverter roller arc plate 19 is located above the lower transfer diverter roller 7. The design of the lower transfer diverter roller arc plate 19 can stabilize the airflow during fiber transfer, guide the fiber to adhere to the roller surface of the lower transfer diverter roller 7, reduce fly waste, and improve fiber transfer efficiency.

[0028] In this embodiment, a motor 20 is mounted and fixed on the rear outer wall of the U-shaped frame 1 by a bracket. The output shaft end of the motor 20 is fixedly connected to the rear end of the rotating shaft 2. The motor 20 is used to drive the rotating shaft 2 and the intermediate doffer 3 to rotate.

[0029] With the above structure, when the multi-cavity diversion device of the carding machine provided in this application is in use, the motor 20 is started and the output shaft of the motor 20 drives the rotating shaft 2 and the intermediate doffer 3 to rotate synchronously. When the fiber conveyed by the carding cylinder on the carding machine approaches the intermediate doffer 3, the rotating intermediate doffer 3 first plays the role of receiving and initially guiding the fiber. When the rotating shaft 2 rotates, the driving gear 21 at its front end rotates synchronously. Since the driven gear 9 and driven gear 14 mesh with the driving gear 21 and have the same diameter, they drive the upper drive shaft 8 and the lower drive shaft 13 to rotate synchronously. When the upper drive shaft 8 rotates, the main pulley 10 on it drives the auxiliary pulley 11 to rotate through the belt 12, which in turn causes the rotating shaft 4 to rotate, ultimately realizing the rotation of multiple upper transfer diverting rollers 6. Similarly, the main pulley 15 on the lower drive shaft 13 drives the auxiliary pulley 16 to rotate through the belt 17, which drives the rotating shaft 5 and multiple lower transfer diverting rollers 7 to rotate. This allows the upper transfer diverting rollers 6 and the lower transfer diverting rollers 7 to rotate in opposite directions to the intermediate doffer 3. The rotation speeds of the upper transfer diverting rollers 6 and the lower transfer diverting rollers 7 are kept consistent. At this time, the upper transfer diverting rollers 6 and the lower transfer diverting rollers 7, which are arranged in an alternating pattern and at equal intervals, rotate synchronously. The diverting roller 7 begins to divert the fibers. Multiple upper diverting rollers 6 and multiple lower diverting rollers 7 form different cavity channels. The spacing between adjacent upper diverting rollers 6 is designed to be greater than the length of the lower diverting rollers 7, ensuring that the fibers are fully diverted. This allows some fibers on the middle doffer 3 to be received by the rotating upper diverting rollers 6 and transferred towards the main cylinder, while other fibers are received by the rotating lower diverting rollers 7 and transferred synchronously towards the main cylinder. During this process, the upper diverting roller arc plate 18 and the lower diverting roller arc plate 19 in the U-shaped frame 1 stabilize the airflow during fiber transfer, guide the fibers to adhere to the roller surfaces of the upper diverting rollers 6 and the lower diverting rollers 7, reduce fly waste, and ensure efficient fiber transfer to the main cylinder. Finally, the fibers diverted and transferred through different channels converge at the main cylinder, greatly improving the uniformity of fiber mixing and enhancing the uniformity and quality of the fiber web.
