Description

Technical Field

[0001] This utility model relates to the field of drawing frames, specifically to a drawing frame for cotton yarn processing with a cleaning function. Background Technology

[0002] A drawing frame is a textile machine mainly used to combine multiple cotton slivers or fiber slivers into one strand for use in subsequent textile processes. At the same time, the drawing frame adopts an automated control system, which has functions such as automatic feeding, automatic drawing, and automatic cutting. It is easy to operate and has high production efficiency.

[0003] A Chinese patent publication (CN218539927U) discloses a draw frame that is easy to clean. The frame includes a draw frame body with a draw frame coil at its lower end. A first connecting rod is rotatably connected to the inner side of the draw frame body. A second connecting rod is rotatably connected to the end of the first connecting rod away from the draw frame body. A cleaning rod is inserted through the end of the second connecting rod away from the first connecting rod. A movable plate is fixedly connected to one end of the cleaning rod, and the movable plate is fixedly connected to one end of a traction rope. This novel, easy-to-clean draw frame allows for easy cleaning of the slanted tube on the draw frame coil. By rotating the first and second connecting rods, the cleaning rod is aligned with the slanted tube. The operator steps on a foot pedal, which moves the traction rope upwards, allowing the cleaning rod to enter the slanted tube. The operator releases the foot pedal, and a spring returns the cleaning rod. This process is repeated to easily clean the inside of the slanted tube.

[0004] When the aforementioned drawing frame is in use, the movement of the foot pedal restricts the range of movement of the cleaning rod. This limits the cleaning range of the cleaning rod and may result in incomplete cleaning of the slanted tubes on the drawing frame coil, affecting the processing of cotton fibers inside the slanted tubes on the drawing frame coil.

[0005] Therefore, it is necessary to invent a drawing frame for cotton yarn processing that has a cleaning function to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a drawing frame for cotton yarn processing with a cleaning function, in order to solve the problem mentioned in the background art that when the drawing frame is in use, the movement of the foot pedal restricts the movement range of the cleaning rod, which results in a limited cleaning range of the cleaning rod and may lead to incomplete cleaning of the slanted tubes on the drawing frame, affecting the processing of cotton fibers inside the slanted tubes on the drawing frame.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drawing frame for cotton yarn processing with a cleaning function, comprising a drawing frame body, a window on the side of the drawing frame body, and a rotating rod rotatably mounted inside the window via a rotating assembly, with a sleeve fixedly fitted on the outer ring of the rotating rod, one end of a flexible hose fixedly connected to the outer wall of the sleeve, the flexible hose being wound and mounted on the outer wall of the sleeve, and a cleaning head fixedly mounted on the other end of the flexible hose, the cleaning head penetrating into the drawing frame coil, the rotating rod having its rotation angle limited by a limiting assembly, and a lifting ring fixedly mounted on the inner wall of the drawing frame body, with the cleaning head engaged inside the lifting ring.

[0008] Preferably, there are two windows, and the two windows are symmetrically arranged with reference to the central axis of the drawing frame body, so as to facilitate the alternating use of the two sets of cleaning heads.

[0009] Preferably, the rotating assembly includes a dial fixedly connected to the lower end of the rotating rod, and the dial is rotatably connected to a notch reserved on the side of the drawing frame body. Furthermore, the top plate fixedly installed on the top of the rotating rod is rotatably connected to a rotating groove reserved inside the drawing frame body, thereby ensuring the stability of the rotating rod's rotation.

[0010] Preferably, the outer wall of the dial is attached to the inner wall of the notch to achieve a rotatable connection, and the side of the dial protrudes from the side of the drawing frame body, making it convenient to turn the dial to drive the rotation of the rotating rod to achieve winding and storage of the hose.

[0011] Preferably, the limiting component includes two symmetrically arranged movable slots preset inside the main body of the drawing frame, and the movable slots are movably connected to movable rods by springs, and the movable rods match the snap-fit ​​slots inside the top plate.

[0012] Preferably, the limiting component further includes a vertical plate fixedly connected to the inner wall of the movable groove, and the vertical plate is movably matched with the square groove reserved inside the movable rod. A spring is preset inside the square groove. The spring applies pressure to match the movable rod with the snap-fit ​​groove, thereby limiting the angle position of the rotating rod and preventing the hose wound on the outer ring of the sleeve from loosening.

[0013] Preferably, the end of the movable rod that matches the locking groove is spherical, and the locking groove is hemispherical. The opening of the locking groove is a smooth arc surface, which facilitates the subsequent rotation of the dial to drive the rotating rod to rotate synchronously after being subjected to force. At this time, the locking groove can move and push the movable rod out of the locking groove, so that the rotation of the rotating rod is not affected.

[0014] Preferably, the two ends of the spring are fixedly connected to the vertical plate and the inner wall of the square groove, respectively, to ensure that the elastic movement of the movable rod proceeds smoothly.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention allows the hose to be pulled out, enabling the cleaning head, which is fixedly connected to the end of the hose, to enter the drawing coil disc for cleaning lint, thus ensuring the normal operation of the drawing frame. Simultaneously, the subsequent rotation of the dial drives the rotation of the rotating rod and the sleeve fixedly fitted on the outer wall of the rotating rod, which winds and stores the hose. The spring applies pressure to match the movable rod with the locking groove, thereby limiting the angle position of the rotating rod. This prevents the hose wound around the outer ring of the sleeve from loosening, ensuring a longer service life for the hose. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4The drawing frame for cotton yarn processing shown includes a drawing frame body 1. A window 2 is provided on the side of the drawing frame body 1. A rotating rod 3 is rotatably installed inside the window 2 via a rotating assembly 7. A sleeve 4 is fixedly fitted on the outer ring of the rotating rod 3. One end of a flexible hose 5 is fixedly connected to the outer wall of the sleeve 4. The flexible hose 5 is wound and installed on the outer wall of the sleeve 4. A cleaning head 6 is fixedly installed at the other end of the flexible hose 5. The cleaning head 6 is inserted into the drawing frame coil. The rotation angle of the rotating rod 3 is limited by a limiting assembly 8. A lifting ring 9 is fixedly installed on the inner wall of the drawing frame body 1, and the cleaning head 6 is engaged inside the lifting ring 9.

[0026] This allows the hose 5 to be pulled out, enabling the cleaning head 6, which is fixedly connected to the end of the hose 5, to enter the drawing disc for lint removal. Simultaneously, rotating the dial 701 drives the rotating rod 3 and the sleeve 4 fixedly mounted on the outer wall of the rotating rod 3 to rotate and wind the hose 5 for storage. The spring 806 applies pressure to match the movable rod 802 with the locking groove 803, thereby limiting the angle position of the rotating rod 3. This prevents the hose 5, which is wound around the outer ring of the sleeve 4, from becoming loose, ensuring a longer service life for the hose 5.

[0027] There are two windows 2, and the two windows 2 are symmetrically arranged with reference to the central axis of the main body 1 of the drawing frame, so as to facilitate the alternating use of the two sets of cleaning heads 6.

[0028] To facilitate the rotation of the sleeve 4 for the winding operation of the hose 5, the rotating assembly 7 includes a dial 701 fixedly connected to the lower end of the rotating rod 3. The dial 701 is rotatably connected to the notch 702 reserved on the side of the drawing frame body 1. The top plate 703 fixedly installed on the top of the rotating rod 3 is rotatably connected to the rotating groove 704 reserved inside the drawing frame body 1, ensuring the stability of the rotation of the rotating rod 3. The outer wall of the dial 701 is in contact with the inner wall of the notch 702 to achieve a rotatable connection. The side of the dial 701 protrudes from the side of the drawing frame body 1.

[0029] This makes it easy to turn the dial 701 to drive the rotation of the rotating rod 3, which in turn causes the sleeve 4, which is fitted on the outer ring of the rotating rod 3, to rotate synchronously and rewind the hose 5.

[0030] To ensure the limitation of the subsequent angle of the rotating rod 3, the limiting component 8 includes two symmetrically arranged movable grooves 801 pre-set inside the main body 1 of the drawing frame. The movable rod 802 is movably connected inside the movable groove 801 by a spring 806. The movable rod 802 matches the snap-fit ​​groove 803 inside the top plate 703. The limiting component 8 also includes a vertical plate 804 fixedly connected to the inner wall of the movable groove 801. The vertical plate 804 is movably matched with the square groove 805 reserved inside the movable rod 802. The square groove 805 is pre-set with a spring 806 inside.

[0031] This causes the spring 806 to apply pressure, making the movable rod 802 match the locking groove 803, thereby limiting the angular position of the rotating rod 3, so that the hose 5 wound around the outer ring of the sleeve 4 will not loosen.

[0032] The end of the movable rod 802 that matches the locking groove 803 is spherical, and the locking groove 803 is hemispherical. The groove opening of the locking groove 803 is a smooth arc surface. The two ends of the spring 806 are fixedly connected to the vertical plate 804 and the inner wall of the square groove 805, respectively, to ensure that the elastic movement of the movable rod 802 is smooth.

[0033] This facilitates the subsequent rotation of the dial 701, which in turn causes the rotating rod 3 to rotate synchronously under force. At this time, the locking groove 803 moves and can push the movable rod 802 out of the locking groove 803, so that the rotation of the rotating rod 3 is not affected. Then, the spring 806 applies pressure to match the movable rod 802 with the locking groove 803, thereby limiting the angle position of the rotating rod 3. At the same time, the cleaning head 6, which is fixedly connected to the end of the hose 5, engages with the fixed position hanging ring 9, so that the completed hose 5 will not loosen.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
