Description

Technical Field

[0001] This utility model relates to the field of cotton yarn production technology, specifically to a yarn guiding device for cotton yarn production. Background Technology

[0002] Cotton yarn is made from cotton fibers through spinning processes. After being plied, it is called cotton thread. In the cotton yarn production process, the yarn guiding equipment plays a crucial role. It guides the movement of the yarn in the machine, stabilizes the yarn position and tension, prevents yarn breakage or slack, reduces malfunctions and waste in the production process, and improves production efficiency and capacity.

[0003] Chinese Patent Publication No. CN219058148U discloses a cotton yarn guide device. By setting an adjustment mechanism, the position of the guide roller can be changed, giving the device a tensioning function. By setting a buffer mechanism between the guide roller and the support plate, the buffer mechanism can relieve the force on the guide roller when the cotton yarn is subjected to external force, avoiding the breakage of the cotton yarn and thus improving the processing efficiency of the cotton yarn.

[0004] In the process of realizing this application, the inventors discovered that the above invention, in combination with the existing technology, has at least the following problems: the spring in the buffer mechanism is a consumable part and needs to be replaced regularly after long-term use in order to maintain its performance. Generally, the spring is fixed by screws, which makes disassembly and maintenance difficult. In addition, manual adjustment is required during the tension adjustment process. When the device is used frequently, manual adjustment is time-consuming and laborious, and requires technical skills from the operator, resulting in poor yarn guiding efficiency. Therefore, further improvement is needed. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 In this embodiment, a yarn guiding device for cotton yarn production includes a receiving mechanism, an adjusting mechanism is provided inside the receiving mechanism, a buffer mechanism is provided inside the adjusting mechanism, and a guide wheel 16 is rotatably mounted on the front of the buffer mechanism.

[0017] In this embodiment, the buffer mechanism includes two L-shaped positioning plates 10 and two stabilizing slide rails 11. The L-shaped positioning plates 10 are disposed inside the adjustment mechanism. The stabilizing slide rails 11 are fixedly installed on the left and right sides of the inner wall of the adjustment mechanism, respectively. The stabilizing slide rails 11 are located between the upper and lower L-shaped positioning plates 10. Movable sliders 12 are slidably installed inside the stabilizing slide rails 11. Buffer blocks 13 are fixedly installed between the movable sliders 12. Fixed plates 14 are provided on the opposite side of each L-shaped positioning plate 10. Buffer spring plates 15 are fixedly installed on the opposite side of each fixed plate 14. The opposite side of each buffer spring plate 15 is in contact with the buffer block 13. The fixed plates 14 and buffer spring plates 15 are integrally formed. The upper and lower L-shaped positioning plates 10 are located between the upper and lower fixed plates 14 and the buffer spring plates 15, respectively, and are in contact with the fixed plates 14 and the buffer spring plates 15.

[0018] During the unwinding process, the cotton yarn will bounce, which will exert a certain force on the roller of the guide wheel 16, thereby causing the buffer block 13 to move. The movable slider 12 and the stabilizing slide rail 11 guide the buffer block 13. At this time, the buffer spring plate 15 buffers the bouncing force, thereby preventing the cotton yarn fibers from floating up and becoming taut, which could cause the yarn to break. Specifically, after the buffer spring plate 15 has been used for a period of time, pulling the front side of the fixing plate 14 outward will allow the fixing plate 14 and the buffer spring plate 15 to detach together from the L-shaped positioning plate 10. Then, the new fixing plate 14 and the buffer spring plate 15 can be snapped back onto the L-shaped positioning plate 10, thus achieving quick disassembly and maintenance of the fixing plate 14 and the buffer spring plate 15, which is simple and convenient.

[0019] In this embodiment, the receiving mechanism includes a support base 1, a cover plate 2 is detachably installed on the front side of the support base 1, and a connector 3 is detachably installed on the back side of the support base 1.

[0020] The cover plate 2 and the connecting piece 3 are both fixed to the bearing seat 1 by bolts and nuts, which makes it convenient to maintain the internal adjustment mechanism.

[0021] In this embodiment, the adjustment mechanism includes a rotating shaft 4 and a reduction motor 7. The rotating shaft 4 is rotatably mounted on the rear side of the inner wall of the bearing seat 1. The rotating shaft 4 passes through and extends to the front side of the cover plate 2. An adjustment arm 5 is fixedly mounted on the front side of the rotating shaft 4. A driven worm gear 6 is fixedly mounted on the outside of the rotating shaft 4. The reduction motor 7 is fixedly mounted on the top of the bearing seat 1. An active worm gear 8 is fixedly mounted on the output end of the reduction motor 7. The active worm gear 8 passes through and extends into the interior of the bearing seat 1. The active worm gear 8 meshes with the driven worm gear 6. An L-shaped positioning plate 10 is fixedly mounted inside the receiving hole 9 at the right end of the front side of the adjustment arm 5. A stabilizing slide rail 11 is fixedly mounted on the left and right sides of the inner wall of the receiving hole 9.

[0022] Specifically, when the cotton yarn becomes loose, the geared motor 7 can be started to drive the active worm gear 8 to rotate, which in turn drives the driven worm wheel 6 to rotate. This causes the rotating shaft 4 to rotate and adjust the position of the adjusting arm 5, which in turn causes the buffer mechanism to change the position of the guide wheel 16. Thus, the tension can be adjusted according to the actual situation, replacing manual adjustment and improving adjustment efficiency and accuracy.
