[0002] In the continuous production of products such as films, the edge filaments generated during the edge trimming process need to be recycled by an edge filament winding machine. Traditional edge filament winding machines directly wind up the trimmed edge filaments, but because the filaments are scattered and disordered, they can easily interfere with the running production line. To solve this problem, existing technologies use guide pulley devices to guide the path of the edge filaments. Currently, the common installation method for edge filament guide pulleys is to use a threaded rod with double nuts for fixing. The edge filament guide pulley is movably sleeved on the threaded rod, and the nuts are used to limit the position of the edge filament guide pulley. This installation method requires the operator to tighten two nuts sequentially, reducing the efficiency of adjusting the position of the edge filament guide pulley. Based on this, this application proposes an edge filament guide pulley for use in an edge filament winding machine. Utility Model Content

[0019] 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.

[0020] This utility model provides embodiments: Please refer to Figures 1-5 The edge yarn guide pulley used in the edge yarn winding machine includes a bearing and a guide wheel body 3 adapted to the edge yarn. The guide wheel body 3 is provided on the outer wall of the bearing. The bearing includes an outer ring 1 and an inner ring 2. Multiple rolling elements, such as balls, are evenly distributed between the outer ring 1 and the inner ring 2. The relative rotational motion between the outer ring 1 and the inner ring 2 is achieved by the rolling of the rolling elements. The guide wheel body 3 is located on the outer wall of the outer ring 1. Ventilation grooves 8 are evenly provided on the outer wall of the outer ring 1. The ventilation grooves 8 increase the contact area between the bearing and the air, accelerate the conduction of heat from the inside of the bearing to the outside air, improve the heat dissipation speed of the bearing, prevent heat accumulation, and facilitate the use of the bearing.

[0021] Both ends of the bearing are equipped with fixing nuts, which are connected to the inner ring 2 of the bearing via a connecting structure. The top and bottom ends of the inner ring 2 are each provided with a movable groove 14. The connecting structure includes a first connecting rod 19, a second connecting rod 10, and a roller 15. The first connecting rod 19 and the second connecting rod 10 are adapted to the movable groove 14. Through the movable groove 14, the first connecting rod 19 and the inner ring 2 are in a movable connection state, and the second connecting rod 10 and the inner ring 2 are also in a movable connection state. Both the first connecting rod 19 and the second connecting rod 10 are connected to the inner ring 2 via springs 9. Both the first connecting rod 19 and the second connecting rod 10 are provided with springs 9 on their outer sides. The springs 9 are in a compressed state. With the setting of the springs 9, the positions of the first connecting rod 19 and the second connecting rod 10 can be changed under the action of external force. When the external force is released, the first connecting rod 19 and the second connecting rod 10 can be reset under the action of the spring 9. Furthermore, the spring 9 can make the first connecting rod 19 or the second connecting rod 10 fit tightly against the inner ring 2, and the positions of the first connecting rod 19 and the second connecting rod 10 can remain unchanged.

[0022] The first connecting rod 19 and the second connecting rod 10 are connected by a pull rope 11. The inner sides of both ends of the pull rope 11 are in contact with the outer side wall of the roller 15, respectively. Figure 3 and Figure 4 As shown, the two ends of the pull rope 11 move in opposite directions. When the first connecting rod 19 moves, the second connecting rod 10 moves in opposite directions under the action of the pull rope 11.

[0023] The fixing nut has a two-part structure, including an active part 4 and a driven part 5. A handle 7 is provided in the middle of the outer wall of the active part 4. The two active parts 4 are connected by a first connecting rod 19, and the two driven parts 5 are connected by a second connecting rod 10.

[0024] As described above, under the action of the connecting structure, when the user moves the active part 4 via the handle 7, the active part 4 moves the first connecting rod 19. The first connecting rod 19 then moves the second connecting rod 10 via the pull rope 11, allowing the active part 4 and the driven part 5 to move in opposite directions. When the restriction on the active part 4 is released, the active part 4 and the driven part 5 can return to their original positions under the restoring force of the spring 9, enabling them to achieve a tight fit. During use, the fixed nut allows for rapid engagement and disengagement with the matching screw, improving the disassembly and position change speed of this application.

[0025] The top and bottom ends of the first connecting rod 19 and the moving groove 14 are magnetically attracted to each other. Under the action of this attraction, the position of the first connecting rod 19 can remain unchanged. In any configuration, when the active part 4 and the driven part 5 are separated, the position of the active part 4 can remain unchanged under the action of the magnetic attraction between the top ends of the first connecting rod 19 and the moving groove 14, thereby keeping the fixing nut in the open state. This makes it convenient for the user to move the guide pulley along the direction of the fixing screw, and to adjust the position of this application.

[0026] The materials of the first connecting rod 19 and the inner ring 2 can be customized according to requirements, ensuring that the magnetic attraction between the first connecting rod 19 and the inner ring 2 keeps the position of the active part 4 unchanged.

[0027] The outer wall of the inner ring 2 is uniformly provided with ball raceways 18, which are adapted to the rolling elements distributed between the outer ring 1 and the inner ring 2. One end of the inner ring 2 is provided with a uniformly distributed groove 16, and an oil injection hole 13 is provided on the outer side of the uniformly distributed groove 16. An oil injection channel 17 is uniformly provided on the inner side of the uniformly distributed groove 16, which penetrates the ball raceway 18 to form a fluid channel. Through the uniformly distributed groove 16 and the oil injection channel 17, the bearing lubricating oil injected through the oil injection hole 13 can enter the ball raceway 18 through the uniformly distributed groove 16 and the oil injection channel 17, so as to achieve precise lubrication of the rolling elements distributed between the outer ring 1 and the inner ring 2.

[0028] A lubricating oil replenishment hole 12 is provided on the active part 4 near the oil filling hole 13. The lubricating oil replenishment hole 12 is sealed by a sealing plug 6. A sealing plate is provided on the inner wall of the active part 4 near the oil filling hole 13. The sealing plate is used to increase the sealing between the active part 4 and the inner ring 2 to prevent lubricating oil leakage. The material of the sealing plate can be set according to the requirements and is not limited here.

[0029] In summary: When using the edge thread guide pulley of this edge thread winding machine, to ensure the normal operation of the edge thread winding machine, a screw adapted to the edge thread guide pulley is installed between the two edge thread winding machines A and B, and the edge thread guide pulley is sleeved on the screw. The user moves the position of the edge thread guide pulley. When the edge thread guide pulley is in the correct position, the user presses the handle 7. Under the action of the pressing force, the handle 7 drives the first connecting rod 19 to approach the second connecting rod 10 through the active part 4. Under the action of the spring 9's rebound force, the second connecting rod 10 approaches the first connecting rod 19. The second connecting rod 10 drives the driven part 5 connected to it to move until the active part 4 and the driven part 5 are in a tight fit. At this time, the fixing nut formed by the active part 4 and the driven part 5 is in a meshing state with the screw, realizing the fixation of the edge thread guide pulley on the screw. At this time, the bottom end of the first connecting rod 19 and the matching moving groove 14 are in a magnetic attraction state, preventing the active part 4 and the driven part 5 from separating. The edge guide pulley can guide the edge wire to be wound, making it easier to wind up. During the guiding process, the ventilation groove 8 increases the contact area between the present application and the air, improving the heat dissipation speed of the present application. When it is necessary to add lubricating oil to the bearing, the user can inject lubricating oil into the ball raceway 18 through the lubricating oil replenishment hole 12, the oil injection hole 13, the uniform distribution groove 16 and the oil injection channel 17 to achieve precise lubrication of the rolling elements distributed between the outer ring 1 and the inner ring 2.
