Description

Technical Field

[0001] This utility model relates to the field of ring spinning machine technology, specifically to a ring spinning machine traction mechanism. Background Technology

[0002] The drafting mechanism of a spinning frame is one of the most crucial components in the spinning process. It is responsible for uniformly drawing the roving to the target diameter, preparing it for subsequent twisting and winding. Its design directly affects the yarn's uniformity, strength, and production efficiency.

[0003] In the prior art, patent application CN202020749125.5 discloses a traction device for a spinning frame, including a movable frame and a fixed frame mounted on the spinning frame. A first pressure roller group, a second pressure roller group, and a third pressure roller group are sequentially arranged on the fixed frame. A first slip roller group, a second slip roller group, and a third slip roller group are sequentially arranged on the movable frame. The first pressure roller group and the first slip roller group both have the following structure: they include two guide rollers with a rubber ring wrapped around their outer surfaces. The axis connecting the two guide rollers of the first slip roller group is inclined upwards. The third pressure roller group and the third slip roller group both have the following structure: they include two guide rollers with a rubber ring wrapped around their outer surfaces. The axis connecting the two guide rollers of the third pressure roller group and the third slip roller group is inclined downwards. The traction device for a spinning frame obtained by this utility model, through its reasonable structural design, can effectively improve the stability of the spinning frame in traction and stretching of the yarn, ensuring the quality of the spinning yarn.

[0004] In the traction device of existing spinning machines, the pressure roller is covered with a rubber ring belt to increase the friction between the pressure roller and the yarn, ensuring the stability of the yarn during traction. However, the rubber ring belt in the existing technology will gradually wear down during long-term use. Since the rubber ring belt is taut on the pressure roller, when the wear becomes too severe, removing the old rubber ring belt from the pressure roller will cause the rubber ring belt to break into pieces, making disassembly inconvenient. At the same time, when installing a new rubber ring belt on the pressure roller, a great deal of force is required to pry the rubber ring belt open. This makes the replacement of the rubber ring belt time-consuming and laborious. Utility Model Content

[0005] The purpose of this utility model is to provide a traction mechanism for a spinning machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a traction mechanism for a spinning machine, comprising: a pressure roller and a rubber ring belt, wherein the pressure roller has a rubber ring belt mounting groove, and a rubber ring belt liner is fixed on the rubber ring belt. Both the rubber ring belt liner and the rubber ring belt have a semi-circular plate structure, with both ends of the rubber ring belt liner exposed. An mounting ring plate is slidably connected to the pressure roller, and the mounting ring plate has an annular plate structure. The inner ring of the mounting ring plate is slidably connected to the rubber ring belt liner.

[0007] Preferably, both the rubber ring liner and the rubber ring are provided in two sets.

[0008] Preferably, the mounting ring plate is provided in two sets, and the two sets of mounting ring plates are symmetrically distributed about the rubber ring belt mounting groove.

[0009] Preferably, the pressure roller has guide holes and spring grooves, both of which are cylindrical groove structures, and the diameter of the spring groove is larger than that of the guide hole.

[0010] Preferably, one end of the guide rod is fixed to the mounting ring plate, and the other end of the guide rod is fixed to a spring plate. The guide rod has a circular rod structure, and the spring plate has a circular plate structure.

[0011] Preferably, the end of the guide rod away from the mounting ring plate is movably inserted into the guide hole, the spring plate is slidably connected in the spring groove, and a spring is movably connected in the spring groove.

[0012] Preferably, the pressure roller has a screw hole, in which a screw is movably connected. The screw hole has an internal thread, and the screw has an external thread. The external thread of the screw mates with the internal thread of the screw hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The spinning machine traction mechanism proposed in this utility model allows for the removal of the old rubber ring belt when the rubber ring belt is severely worn. The mounting ring plate is pushed away from the rubber ring belt liner, allowing the two sets of semi-circular cylindrical rubber ring belt liners and the rubber ring belt itself to be removed from the rubber ring belt mounting groove. The old rubber ring belt liner is then disassembled. Next, two new sets of rubber ring belts and rubber ring belt liners are placed into the rubber ring belt mounting groove to form a circular cylindrical structure. Finally, the mounting ring plate moves back onto the surface of the two sets of rubber ring belt liners, fitting onto them and thus confining the rubber ring belt liners within the rubber ring belt mounting groove. This facilitates convenient replacement of the rubber ring belt, saving time and effort. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 3 This utility model provides a technical solution: a traction mechanism for a spinning frame, comprising: a pressure roller 1 and a rubber ring belt 4. The pressure roller 1 has a rubber ring belt mounting groove 2. A rubber ring belt liner 3 is fixed on the rubber ring belt 4. Both the rubber ring belt liner 3 and the rubber ring belt 4 have a semi-circular plate structure, with both ends of the rubber ring belt liner 3 exposed. A mounting ring plate 5 is slidably connected to the pressure roller 1. The mounting ring plate 5 has an annular plate structure, and its inner ring is slidably connected to the rubber ring belt liner 3. Two sets of mounting ring plates are provided for both the rubber ring belt liner 3 and the rubber ring belt 4. Two sets of mounting ring plates 5 are provided, symmetrically distributed about the rubber ring belt mounting groove 2. The pressure roller 1 has guide holes 6 and spring grooves 8. Both the guide holes 6 and spring grooves 8 are cylindrical groove structures. The diameter of the spring groove 8 is larger than that of the guide holes 6. One end of the guide rod 7 is fixed on the mounting ring plate 5, and the other end of the guide rod 7 is fixed with a spring plate 9. The guide rod 7 is a circular rod structure, and the spring plate 9 is a circular plate structure. The end of the guide rod 7 away from the mounting ring plate 5 is movably inserted into the guide hole 6, and the spring plate 9 is slidably connected in the spring groove 8. A spring 10 is movably connected in the spring groove 8.

[0021] In actual use, the rubber ring belt 4 in this application is changed from the prior art where two sets of pressure rollers 1 share one set of rubber ring belt 4 to each set of pressure rollers 1 using a separate set of rubber ring belt 4. Furthermore, the shape of the rubber ring belt 4 is changed from the elliptical cylindrical structure of the prior art to a semi-circular cylindrical structure. When the rubber ring belt 4 is worn excessively, the mounting plate 5 is pushed away from the rubber ring belt 4, and the mounting plate 5 is removed from the rubber ring belt liner 3. Then, the two sets of semi-circular cylindrical rubber ring belt liners 3 and the rubber ring belt 4 can be removed together from the rubber ring belt mounting groove 2, completing the disassembly of the old rubber ring belt liner 3. Afterwards, the two new sets of rubber ring belts... 4. The rubber ring belt liner 3 is placed into the rubber ring belt mounting groove 2 to form a cylindrical structure. Finally, the mounting ring plate 5 is moved back to the surface of the two sets of rubber ring belt liners 3. The mounting ring plate 5 is fitted onto the two sets of rubber ring belt liners 3, thereby limiting the rubber ring belt liners 3 in the rubber ring belt mounting groove 2, which can realize the convenient replacement of the rubber ring belt 4, making the replacement of the rubber ring belt 4 time-saving and labor-saving. At the same time, the compressed spring 10 generates a thrust towards the rubber ring belt 4 on the spring plate 9. This thrust is transmitted to the mounting ring plate 5 through the spring plate 9 and the guide rod 7 in the guide hole 6, so that the mounting ring plate 5 is kept fitted onto the rubber ring belt liner 3.

[0022] Example 2: Based on Example 1, in order to replace the spring 10, a screw hole 11 is provided on the pressure roller 1, and a screw 12 is movably connected in the screw hole 11. The screw hole 11 has an internal thread, and the screw 12 has an external thread. The external thread of the screw 12 mates with the internal thread of the screw hole 11.

[0023] When the spring 10 loses its elasticity significantly after long-term use, use a screwdriver to remove the screw 12 from the screw hole 11, then remove the old spring 10 from the spring slot 8, install the new spring 10 into the spring slot 8, and then install the screw 12 back into the screw hole 11 to replace the spring 10.

[0024] In practical use, the rubber ring belt 4 in this application is changed from the prior art where two sets of pressure rollers 1 share one set of rubber ring belt 4 to each set of pressure rollers 1 using a separate set of rubber ring belt 4. Furthermore, the shape of the rubber ring belt 4 is changed from the elliptical cylindrical structure of the prior art to a semi-circular cylindrical structure. When the rubber ring belt 4 is worn excessively, the mounting ring plate 5 is pushed away from the rubber ring belt 4, and the mounting ring plate 5 is removed from the rubber ring belt liner 3. Then, the two sets of semi-circular cylindrical rubber ring belt liners 3 and the rubber ring belt 4 can be removed together from the rubber ring belt mounting groove 2, completing the disassembly of the old rubber ring belt liner 3. Afterwards, the two new sets of rubber ring belts 4 and rubber ring belt liners 3 are placed into the rubber ring belt mounting groove 2 to form a circular cylindrical structure. Finally, the mounting ring plate 5 is moved back to the surface of the two sets of rubber ring belt liners 3. On the surface, the mounting ring plate 5 is fitted onto the two sets of rubber ring belt liners 3, thereby limiting the rubber ring belt liners 3 in the rubber ring belt mounting groove 2, which enables convenient replacement of the rubber ring belt 4, saving time and effort. At the same time, the compressed spring 10 generates a pushing force towards the rubber ring belt 4 on the spring plate 9. This pushing force is transmitted to the mounting ring plate 5 through the spring plate 9 and the guide rod 7 in the guide hole 6, so that the mounting ring plate 5 is kept fitted onto the rubber ring belt liners 3. When the spring 10 loses its elasticity due to long-term use, the screw 12 is removed from the screw hole 11 with a screwdriver, and then the old spring 10 can be taken out from the spring groove 8. The new spring 10 is installed into the spring groove 8, and then the screw 12 is installed back into the screw hole 11, thus replacing the spring 10.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
