Description

Technical Field

[0001] The utility model relates to the technical field of textile machines, in particular to a warping device for a loom. Background Technique

[0002] Warping is a process of parallel winding a certain number of warp yarns on a warp beam or a loom beam according to specified lengths and widths. In the prior art, a warping machine for adjusting the length of warping adjusts the length of warping by adjusting the length of the warp tube. This will increase the width and floor area of the machine, increase the operation difficulty of workers, and reduce the space utilization rate in the factory.

[0003] In view of the above problems, those skilled in the art have improved the prior art. For example, a warping length adjusting device for a warping machine with the publication number of CN219907993U includes a warping machine main body, a perforated plate fixedly arranged at the rear of the upper end of the warping machine main body, and a guide roller fixedly arranged in the middle of the upper end of the warping machine main body. The warping machine main body includes a first box body. A motor is fixedly arranged on the right side in the middle of the first box body. A rotating rod is fixedly arranged on the output shaft of the motor. A warp tube is fixedly arranged in the middle of the rotating rod. Side plates are fixedly arranged at both ends of the warp tube. An adjusting component is fixedly arranged at the other end of the side plate. The adjusting component includes a fixed block fixedly arranged with the side plate. An adjusting component is arranged at the other end of the adjusting component. It can increase the number of warping turns by expanding the winding diameter of the warp tube, thereby increasing the warping length. However, the above device needs to be operated in cooperation with multiple power sources, and there is no mechanism for locking the diameter of the warp tube in the above device, so it is still inconvenient to use.

[0004] To sum up, it is obvious that there are inconveniences and defects in the prior art in actual use, so it is necessary to improve it. Content of the Utility Model

Specific implementation manner

[0021] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] See Figures 1 to 4 , the present utility model provides a warping device for a loom, including a base 1, a warping assembly 2 and a driving assembly 3. The base 1 is arranged on the ground or other supporting surfaces, the warping assembly 2 is detachably connected to the base 1, and the driving assembly 3 for driving the warping assembly 2 to rotate is also arranged on the base 1.

[0023] See Figures 1 to 4 , the warping assembly 2 includes two end plates 21 and a central shaft 22. The central shaft 22 is rotatably arranged between the two end plates 21. A moving seat 23 is arranged on the central shaft 22. Circulation grooves are arranged on the surfaces of the central shaft 22 near both ends, and the directions of the two circulation grooves are opposite. Through holes for the central shaft 22 to pass through are arranged on the moving seat 23, and guide posts cooperating with the circulation grooves are arranged on the inner side walls of the through holes. When the central shaft 22 rotates unidirectionally, the two moving seats 23 move synchronously and reciprocally in opposite directions. A plurality of outer support plates 24 are evenly arranged around the central shaft 22. A plurality of sliding grooves 26 are arranged on the side walls of the end plates 21 close to each other. The plurality of sliding grooves 26 on the same end plate 21 cooperate with the plurality of outer support plates 24 one by one. Connecting rods 25 are rotatably arranged between the outer support plates 24 and the moving seats 23, that is, one end of the connecting rod 25 is rotatably connected to the outer support plate 24, and the other end of the connecting rod 25 is rotatably connected to the moving seat 23. When the two moving seats 23 move away from each other, the plurality of outer support plates 24 move synchronously away from the central shaft 22, and when the two moving seats 23 move close to each other, the plurality of outer support plates 24 move synchronously close to the central shaft 22.

[0024] See Figures 1 to 4, on the top surface of the base 1, there are two arc-shaped supporting plates 12. The two arc-shaped supporting plates 12 are respectively matched with the two end plates 21 (both end plates 21 are circular plates), which can not only provide support for the end plates 21, but also limit the end plates 21, so that the end plates 21 can only rotate. On the side wall of one of the end plates 21 away from the moving seat 22, there is a fixed shaft 211. At one end of the fixed shaft 211 away from the end plate 21, there is a fixed gear 28. One end of the central shaft 22 close to the fixed gear 28 passes through the end plate 21, the fixed shaft 211 and the fixed gear 28 and then is connected to the sliding gear 27. There is a groove on the central shaft 22, and there is an avoidance hole on the sliding gear 27 for the central shaft 22 to pass through. On the inner side wall of the avoidance hole, there are convex strips matched with the groove, so that the sliding gear 27 can not only slide along the groove, but also drive the central shaft 22 to rotate. On the side wall of the fixed gear 28 close to the sliding gear 27, there is a locking groove matched with the sliding gear 27. When the sliding gear 27 is located in the locking groove, relative rotation cannot occur between the central shaft 22 and the end plate 21, that is, the locking of the central shaft 22 is realized.

[0025] See Figures 1 to 4 , the driving component 3 includes a rotating shaft 31 and an electromagnet 35. The rotating shaft 31 is rotatably arranged at one end of the base 1 close to the fixed shaft 211. One end of the rotating shaft 31 is rotatably connected to the base 1, and the other end of the rotating shaft 31 is connected to the output shaft of the driving member 32. The driving member 32 is arranged on the base 1, and the driving member 32 can drive the rotating shaft 31 to rotate reciprocally. A forward rotation gear 33 and a reverse rotation gear 34 are rotatably arranged on the rotating shaft 31. On one side wall of the forward rotation gear 33, there is a forward ratchet. The forward ratchet, the forward rotation gear 33 and the rotating shaft 31 are concentric. A forward ratchet pawl that can rotate unidirectionally is rotatably arranged on the rotating shaft 31. The forward ratchet is matched with the forward ratchet pawl. On one side wall of the reverse rotation gear 34, there is a reverse ratchet. The reverse ratchet, the reverse rotation gear 34 and the rotating shaft 31 are concentric. A reverse ratchet pawl that can rotate unidirectionally is rotatably arranged on the rotating shaft 31. The reverse ratchet pawl is matched with the reverse ratchet, and the directions of the forward ratchet and the reverse ratchet are opposite. An electromagnet 35 is arranged on the side wall of the base 1 close to the sliding gear 27. The sliding gear 27 is made of a magnetic material. The electromagnet 35 can be matched with the sliding gear 27 to drive the sliding gear 27 to slide reciprocally along the groove. When the electromagnet 35 exerts an attractive force on the sliding gear 27 and the sliding gear 27 is at the end of its movement range closest to the electromagnet 35, the sliding gear 27 meshes with the forward rotation gear 33. When the electromagnet 35 exerts a repulsive force on the sliding gear 27 and the sliding gear 27 is at the end of its movement range farthest from the electromagnet 35, the sliding gear 27 is matched with the locking groove. During this process, the reverse rotation gear 34 is always meshed with the fixed gear 28.

[0026] See Figures 1 to 4, Preferably, the user can add a spring (not shown in the figure) between the fixed gear 28 and the sliding gear 27. Both ends of the spring are connected to gaskets, and the two gaskets are respectively rotatably connected to the fixed gear 28 and the sliding gear 27. When the spring is in its natural state, the sliding gear 27 is in a mating state with the locking groove, which can improve the stability of the warping assembly 2.

[0027] See Figures 1 to 4 , Preferably, a tensioning shaft 11 is rotatably provided on the base 1, which can assist in completing the warping operation.

[0028] See Figures 1 to 4 , Preferably, the outer support plates 24 are provided with arc-shaped surfaces, and their surfaces are all made smooth to avoid damaging the warp threads.

[0029] See Figures 1 to 4 , Preferably, the top surfaces of the arc-shaped support plates 12 are provided with smooth surfaces, which can reduce the wear between the arc-shaped support plates 12 and the end plates 21 and extend the service life of the device.

[0030] In the implementation process of the present utility model: The user first places the warping assembly 2 on the base 1. The two end plates 21 are respectively abutted against the inner side walls at both ends of the base 1. The arc-shaped support plates 12 provide support and limit for the warping assembly 2. Then, the warp threads are wound around the outside of several outer support plates 24 after passing through the tensioning shaft 11. The driving member 32 is started, and the driving member 32 rotates in reverse. At this time, the positive ratchet does not cooperate with the positive pawl, and the reverse ratchet cooperates with the reverse pawl. The positive rotation gear 33 does not rotate, and the reverse rotation gear 34 drives the fixed gear 28 to rotate, thereby driving the warping assembly 2 to rotate and complete the warping.

[0031] When it is necessary to adjust the diameter of the warping assembly 2, the electromagnet 35 is first started. The electromagnet 35 exerts an attractive force on the sliding gear 27, causing the sliding gear 27 to move away from the end plate 21. The sliding gear 27 is disengaged from the locking groove. Then, the driving member 32 is started, and the driving member 32 rotates forward. At this time, the positive ratchet cooperates with the positive pawl, and the reverse ratchet does not cooperate with the reverse pawl. The reverse rotation gear 34 does not rotate, and the positive rotation gear 33 drives the sliding gear 27 to rotate, thereby driving the two moving seats 23 to move synchronously in the opposite direction to adjust the position of the outer support plates 24.

[0032] The present utility model provides a warping device for a loom, and its beneficial effects are as follows:

[0033] 1. By providing a warping assembly, the overall diameter of the warping assembly can be adjusted according to the requirements of the user, meeting the needs of the user and expanding the scope of application.

[0034] 2. By providing a driving assembly, the adjustment of the outer diameter of the warping assembly and the warping operation can be automatically completed, reducing the manufacturing and use costs and improving the warping efficiency.

[0035] In summary, the beneficial effects of the present utility model are as follows: It can automatically complete the adjustment of the outer diameter of the warping component and the warping operation, expand the scope of application, reduce the use cost, and improve the warping efficiency.

[0036] Of course, the present utility model can also have multiple embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
