Description

Technical Field

[0001] This invention relates to the field of cotton yarn production technology, and in particular to a cotton yarn grabbing device for cotton yarn production. Background Technology

[0002] In the cotton processing industry, the cotton grabber, as the core equipment in the cotton opening and cleaning process, primarily tasks itself to evenly grab raw cotton from cotton bales and transport it via airflow to subsequent processes for further processing. The efficiency and stability of the cotton grabbing process directly affect the overall production line's capacity and product quality. With the textile industry's increasing demands for automation and continuous production, the performance and ease of maintenance of cotton grabber equipment are receiving increasing attention.

[0003] Existing cotton-grabbing devices suffer from several technical problems that restrict production efficiency during actual operation. First, during cotton conveying, due to airflow fluctuations, inadequate sealing, or gaps at pipe connections, some fibrous materials easily leak and escape from the conveying system. This not only wastes raw materials and increases production costs, but the escaped cotton fibers may also accumulate around the equipment or in the workshop environment, affecting hygiene and even posing a fire hazard. Second, raw cotton contains cottonseed hulls, impurities, and short fibers, which are easily caught and accumulated at pipe bends, diameter changes, or the inner walls of the conveying channel during pneumatic conveying, gradually forming blockages. Blockages in the cotton outlet pipe directly interrupt cotton grabbing, requiring machine shutdown and manual cleaning. Traditional cleaning methods often require disassembling the pipe, which is cumbersome and time-consuming, severely impacting the continuity and stability of production.

[0004] As the core actuator of the cotton-grabbing assembly, the cotton-grabbing shaft comes into direct contact with the cotton and bears a certain mechanical load during operation. After long-term operation, it is prone to wear or deformation and needs to be replaced regularly. However, the cotton-grabbing shafts of existing cotton-grabbing equipment mostly adopt a fixed installation structure, which makes the disassembly process complicated. It usually requires special tools and a long downtime, which not only increases the difficulty of maintenance but also reduces the time utilization rate of the equipment. Summary of the Invention

Adjusting block 3 314 drives motor 12 311 to move synchronously with coupling 1 215. Since clamping block 306 fixes the cotton-grabbing shaft 216, mounting block 304 slides on mounting block 2 303 to compress spring 305. After the cotton-grabbing shaft 216 is released from coupling 220, motor 10 is started. Electric cylinder 311 and electric cylinder 7 317 move locking plate 318, which presses mounting block 304 onto mounting block 203 to fix it. Motor 12 311 loosens bolt 230, releasing coupling 1 215 from the cotton-gripping shaft 216. Electric cylinder 5 308 then moves adjusting block 2 313, which in turn moves motor 12 311 from coupling 1 215 to the cotton-gripping shaft 216. Pull out the bolt 230 of 15, then start the electric cylinder 3 208. The electric cylinder 3 208 drives the motor 8 214 to move. At this time, the motor 8 214 drives the coupling 1 215 to be pulled out from the cotton grabbing shaft 216, completing the disassembly of the cotton grabbing shaft 216. Start the electric cylinder 4 302. The electric cylinder 4 302 drives the mounting block 2 303 to reset. The mounting block 2 303 drives the mounting block 3 304 to take the cotton grabbing shaft 216 out of the cotton suction box 201, completing the disassembly of the cotton grabbing shaft 216.

[0038] When it is necessary to install the cotton-grabbing shaft 216, first place the cotton-grabbing shaft 216 between the two sets of clamping blocks 306 and fix the cotton-grabbing shaft 216. Move the cotton suction box 201 to the position of the replacement component 3. Align the two ends of the cotton-grabbing shaft 216 with the second coupling 220 and the first coupling 215 respectively. First, start the electric cylinder 3 208. The electric cylinder 3 208 drives the motor 8 214 to move with the first coupling 215. The first coupling 215 is inserted into the cotton-grabbing shaft 216. The drive motor 12 311 is inserted into the bolt 230 of the first coupling 215. Tighten the bolt 230 with the motor 12 311 to connect the first coupling 215 with the cotton-grabbing shaft. After 216 is fixed, the electric cylinder 208 is started. The electric cylinder 208 pushes the cotton-grabbing shaft 216 to move. Since the clamping block 306 clamps the cotton-grabbing shaft 216, the mounting block 304 moves synchronously with the cotton-grabbing shaft 216. The mounting block 304 compresses the spring 305. The electric cylinder 208 pushes the cotton-grabbing shaft 216 into the coupling 220. The drive motor 11 309 is inserted into the bolt 230 of the coupling 220. The motor 11 309 is started. The motor 11 309 tightens the bolt 230 to complete the fixing of the coupling 220 and the cotton-grabbing shaft 216, and completes the installation of the cotton-grabbing shaft 216.
