Description

Technical Field

[0001] This utility model relates to the field of cotton drawing frames, specifically a drawing frame feeding table for cotton. Background Technology

[0002] In the cotton textile production process, the drawing frame is a key upstream equipment. Its core function is to process multiple cotton slivers after carding or combing into finished cotton slivers (processed slivers) with uniform yarn and straight and parallel fibers through drafting and merging processes, providing high-quality raw materials for subsequent roving and spinning processes. The unloading table, as a core supporting equipment of the drawing frame, undertakes the tasks of receiving, temporarily storing and transferring finished cotton slivers. Its performance directly affects the continuous production efficiency of the drawing frame and the stability of cotton sliver quality.

[0003] Traditional feeding tables are mostly fixed platform structures, and the replacement of cotton sliver cans relies entirely on manual operation. After the coiler of the drawing frame fills a cotton sliver can, the machine must be stopped and the operator must remove the full cotton sliver can and then accurately place the empty cotton sliver can directly under the coiler. The entire can replacement process is usually time-consuming. For high-speed drawing frames, frequent machine stops for can replacement will reduce the effective operating rate of the equipment. At the same time, the manual handling of full cotton sliver cans is labor-intensive and can easily cause occupational injuries to operators. Moreover, the rhythm of manual can replacement is difficult to match with the production rhythm of the drawing frame. Therefore, we have proposed a feeding table for cotton drawing frames.

It helps to position cotton swab tube 2 on the top surface of workbench 1. It contains metal block 21 and provides insertion and installation space for insulating board 10. Threaded rod 8: It is a cylindrical rod with threads on the surface, with circular protrusions at both ends, connecting adjusting protrusion 19 and adjusting protrusion 21. The magnetic force is controlled by rotating and adjusting the position of the insulating plate 10 in the positioning tube 7. Adjusting protrusion 19: It has a block-shaped structure and is fixed on both sides of the insulating plate 10. It serves as the mounting carrier for the threaded rod 8 and works with adjusting protrusion 211 to adjust the position of the insulating plate 10.

By moving its position, it can selectively block or connect the magnetic force between the flexible magnetic block 12 and the metal block 21, thereby controlling the fixation and detachment of the cotton swab tube 2. Adjusting protrusion 2 11: It has a block-shaped structure and is fixed on the outside of the positioning tube 7. It cooperates with adjusting protrusion 1 9 and realizes the stable installation and position adjustment of the insulating plate 10 through the threaded rod 8. Flexible magnetic block 12: It has a magnetic flexible block structure and is fixed to the surface of the synchronous belt 15.

When it is aligned with the flexible magnetic block 12 and the metal block 21, it allows magnetic force to pass through and fixes the cotton sliver tube 2; when it is misaligned, it blocks the magnetic force. Metal block 21: It has a block-shaped metal structure and is fixed inside the positioning tube 7. It is magnetically attracted to the flexible magnetic block 12 to achieve the positioning and fixation of the cotton sliver tube 2 on the synchronous belt 15.

[0028] Working Principle: When the cotton drawing frame unloading platform is in operation, it first enters the initial preparation stage. The operator needs to precisely align one end of the workbench 1 with the outlet of the drawing frame, ensuring that the cotton sliver can 2 pre-installed on the top surface of the workbench 1 is perpendicular to the coiler of the drawing frame, laying the foundation for the subsequent accurate receiving of the cotton sliver. After the alignment is completed, the threaded rod 8 is rotated to adjust the insertion depth of the insulating plate 10 in the insertion hole 19 of the positioning tube 7, until the magnetic suction hole 20 on the insulating plate 10, the metal block 21 in the positioning tube 7, and the flexible magnetic suction block 12 on the synchronous belt 15 are completely aligned. Using the magnetic attraction force between the flexible magnetic suction block and the metal block, the cotton sliver can 2 is stably fixed in the corresponding position on the synchronous belt 15. Then, multiple sliver cans distributed along the conveying direction on the synchronous belt 15... Empty cotton sliver cans 2 are placed sequentially at the position of the flexible magnetic block 12 and fixed by the magnetic structure. Simultaneously, it is carefully checked whether the piston rod of the hydraulic cylinder 3 in the lower can of the cotton sliver can is precisely aligned with the guide groove opened on the guide protrusion 5 on the outer surface of the cotton sliver can 2, ensuring smooth pushing action. After entering the cotton sliver winding stage, the drawing machine is started. The finished cotton sliver, after being processed by the stretching and merging processes, is continuously output through the coiler. At this time, the cotton sliver can 2 corresponding to the coiler is in a stable receiving state. Throughout the winding process, the magnetic attraction between the flexible magnetic block 12 and the metal block 21 continuously provides fixing force, preventing the cotton sliver can 2 from shifting due to workshop vibration or cotton sliver tension fluctuations. At the same time, the bottom surface of the positioning tube 7 remains in contact with the top surface of the workbench 1, further restricting the movement of the cotton sliver can. 2. Vertical swaying effectively prevents problems such as cotton sliver deviation and overlapping, ensuring that the cotton sliver is evenly wound in the cotton sliver can 2. When the coiler of the drawing machine detects that the cotton sliver can 2 is full of cotton sliver through the sensor, it immediately sends a full can signal to the lower feed table. The equipment then enters the full can change stage. The operator rotates the threaded rod 8, causing the insulating plate 10 to slide in the positioning tube 7, causing the magnetic suction hole 20 to be misaligned with the metal block 21 and the flexible magnetic suction block 12. The insulating plate 10 blocks the magnetic force transmission, releasing the fixation of the cotton sliver can 2. Then the hydraulic cylinder 3 starts, and its piston rod extends and precisely inserts into the guide groove of the guide protrusion 5, smoothly pushing the full cotton sliver can 2 along the guide groove to move towards the support plate 4 on the other side of the worktable 1. After the cotton sliver can 2 is stably supported by the support plate 4, the hydraulic cylinder stops. The stopper rod retracts and resets, then the motor 16 starts, driving gear 17 on the output shaft to rotate. Gear 17, through meshing with gear 18, drives the rotating shaft 13 to rotate. The synchronous pulley 14 on the rotating shaft 13 rotates synchronously, thereby driving the synchronous belt 15 to run, conveying the pre-loaded empty cotton sliver cans 2 on the synchronous belt 15 to directly below the coiler. Finally, the threaded rod 8 is rotated in the opposite direction to realign the magnetic suction holes 20, restoring magnetic adsorption and fixation. The empty cotton sliver cans 2 enter the ready-to-wrap state, and finally enter the cycle operation and manual assistance stage. The above-mentioned processes of winding, filling, de-adhesion, transfer, replenishment, and fixing are automatically cycled to achieve continuous production of the drawing frame. When the number of empty cotton sliver cans 2 on the synchronous belt 15 is about to be insufficient, the operator can do so during the intervals of normal equipment operation.The new empty cotton sliver can 2 is fixed to the flexible magnetic block 12 of the synchronous belt 15 using a magnetic positioning structure, ensuring the continuous and efficient operation of the drawing frame and avoiding production interruptions due to a shortage of empty cans.
