[0023] As Figures 4-6As shown, the driving assembly comprises the moving piece 8 and the elastic member I 9 which are adhered to each other, the elastic member I 9 is arranged as a spring I, the moving piece 8 is slidably connected to the inner wall of the sliding groove 7, one end of the elastic member I 9 away from the moving piece 8 is adhered to the inner wall of the sliding groove 7, and the elastic member I 9 is also in a compressed state in the initial state, so as to ensure that the elastic member I 9 can continuously push the moving piece 8, so that the moving piece 8 can be fixed at one end of the sliding groove 7 in the initial state, the end of the moving piece 8 away from the bearing 4 is connected with the lubricating assembly through the traction rope 10, the sliding groove 7 is rotatably connected with the pulley 15 on the bottom surface away from the moving piece 8, the traction rope 10 is slidably connected to the side wall of the pulley 15, the pulley 15 can change the direction of the traction rope 10, and the side wall of the pulley 15 is provided with a groove, the traction rope 10 is slidably connected to the inner wall of the groove, and the groove can reduce the probability of the traction rope 10 sliding out of the pulley 15, the moving piece 8 restricts the lubricating assembly through the traction rope 10, and the lubricating assembly is fixed in the cavity 5 in the initial state, when the outer ring of the bearing 4 is driven to rotate by the inner ring of the bearing 4, the protrusions 6 on the outer ring of the bearing 4 will abut against the moving piece 8 in the rotation and push the moving piece 8 to move on the sliding groove 7, the pulling force of the moving piece 8 on the lubricating assembly through the traction rope 10 is reduced, so that the lubricating assembly can slide on the inner wall of the cavity 5 and enter between the outer ring of the bearing 4 and the inner ring of the bearing 4 to lubricate the bearing 4, and the distance between the protrusions 6 is greater than the length of the sliding groove 7, so that the lubricating assembly can be accommodated in the cavity 5 after one lubrication is completed, and the probability of excessive lubrication of the lubricating assembly in contact with the bearing 4 is reduced.
[0024] As shown in the figure, Figures 2-7 The inner wall of the sliding groove 7 is adhered with a limiting strip 11, the moving piece 8 is slidably connected with the lower surface of the limiting strip 11, the distance between the end of the limiting strip 11 away from the moving piece 8 and the bearing 4 is greater than the distance between the other end of the limiting strip 11 and the bearing 4, the distance between the end of the limiting strip 11 away from the moving piece 8 and the bearing 4 is greater than the distance of the protrusion, the moving piece 8 is arranged in a U shape, the protruding part of the moving piece 8 close to the bearing 4 intermittently abuts against the protrusion 6, and the protruding part of the moving piece 8 away from the bearing 4 is slidably connected with the side wall of the limiting strip 11, the limiting strip 11 limits the moving track of the moving piece 8, and the distance between the moving piece 8 and the bearing 4 is increased in the process of moving of the moving piece 8 driven by the protrusion 6, when the elastic member I 9 is compressed to the minimum length, the protrusion 6 is separated from the moving piece 8, the pushing force of the protrusion 6 on the moving piece 8 disappears, the moving piece 8 returns to the initial position under the pushing force of the elastic member I 9 rebounding, and the pulling force of the lubricating assembly is generated through the traction rope 10, so that the lubricating assembly moves away from the bearing 4 and is accommodated in the cavity 5.
[0025] As shown in the figure, Figures 2-7As shown, the lubricating assembly comprises a support plate 12 and four elastic members 13, which are arranged as springs. One end of the four elastic members 13 is bonded to the side of the support plate 12 away from the bearing 4, and the other end of the four elastic members 13 is bonded to the inner wall of the cavity 5. The end of the traction rope 10 away from the moving piece 8 is bonded to the side of the support plate 12 away from the bearing 4, and the bonding point is the center point of the support plate 12, which can improve the stability of the support plate 12 when it moves under tension. A lubricating strip 14 is bonded to the side of the support plate 12 close to the bearing 4. In the initial state, the elastic members 13 are in a compressed state under the tension of the traction rope 10. When the moving piece 8 moves under the thrust of the protrusion 6, the length of the traction rope 10 between the moving plate and the pulley 15 becomes smaller, thereby increasing the length of the traction rope 10 between the support plate 12 and the pulley 15. The restraint of the support plate 12 by the traction rope 10 becomes smaller, reducing the pressure on the elastic members 13 and causing them to rebound and generate a thrust on the support plate 12. The support plate 12 slides in the direction close to the bearing 4 under the thrust, and the lubricating strip 14 extends into the space between the outer ring of the bearing 4 and the inner ring of the bearing 4 to lubricate the bearing 4.
[0026] As shown in Figures 2-7 , the lubricating strip 14 has elastic deformation performance. The lubricating strip 14 is O-shaped, and the width of the lubricating strip 14 is greater than the sum of half the thickness of the bearing 4 and the length of the protrusion 6. The length of the sliding groove 7 is equal to the distance between the protrusion 6 of the support plate 12. Since the distance that the support plate 12 can move depends on the distance that the moving piece 8 moves, the length of the sliding groove 7 is set to ensure that the lubricating strip 14 can extend into the space between the outer ring of the bearing 4 and the inner ring of the bearing 4 during the sliding of the support plate 12, thereby lubricating the bearing 4. The diameter of the lubricating strip 14 is smaller than the inner diameter of the outer ring of the bearing 4 and greater than the inner diameter of the inner ring of the bearing 4, so that the lubricating strip 14 can smoothly enter the space between the inner ring of the bearing 4 and the outer ring of the bearing 4 during movement and contact the balls inside the bearing 4 for lubrication.
[0027] As shown in Figures 2-4 , the elastic force of the elastic member 9 on the moving piece 8 is greater than the sum of the elastic forces of the four elastic members 13 on the support plate 12. This ensures that the moving piece 8 does not move due to the elastic force of the elastic members 13 when the protrusion is not in contact with the moving piece 8. At the same time, after the thrust of the protrusion on the moving piece 8 disappears, the thrust of the elastic members 13 is sufficient to cause the moving piece 8 to move and drive the lubricating assembly to be accommodated inside the cavity 5.
[0028] Working principle: a kind of cloth spreader, when the bearing 4 of the shaft of the both ends of cloth roller 2 is not lubricated for a long time, the inner ring of bearing 4 will drive the outer ring of bearing 4 to rotate, the outer ring of bearing 4 makes the protrusion 6 move and generates thrust to the moving piece 8 in the process of rotating, the moving piece 8 is moved by the thrust and the constraint of support plate 12 is reduced, the support plate 12 is moved to the direction of bearing 4 under the push of elastic member two 13 and makes the lubricating strip 14 on support plate 12 extend into the outer ring of bearing 4 and the inner ring of bearing 4 to lubricate bearing 4, when the protrusion 6 is separated from the moving piece 8, the elastic member one 9 rebounds and generates thrust to the moving piece 8, so that the moving piece 8 returns to the initial state and generates pull force to the support plate 12, so that the support plate 12 is retracted into the cavity 5.
[0029] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application can also be considered as the protection scope of the present application.
