[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 5This utility model provides an automatic constant force anti-breakage feeding mechanism for coreless grinding machine bushings, including a feeding plate 1, a transport mechanism, a pushing mechanism, and a pressure regulating mechanism. The feeding plate 1 is fixedly connected to the transport mechanism and located on one side of the transport mechanism. The pushing mechanism is located at one end of the transport mechanism, and the pressure regulating mechanism is located in the middle section of the transport mechanism. The pressure regulating mechanism includes two mounting plates 2, a top plate 3, two threaded rods 4, four connecting rods 5, four first springs 6, and a pressure roller 7. The two mounting plates 2 are fixedly connected to the transport mechanism and located on both sides of the transport mechanism belt. The top plate 3 is located above the transport mechanism. The two threaded rods 4 pass through the top plate 3 and are threadedly connected to the corresponding mounting plates 2. The pressure roller 7 is located between the top plate 3 and the transport mechanism. The four connecting rods 5 pass through the top plate 3 and are threadedly connected to the pressure roller 7. The four first springs 6 respectively cover the surface of the corresponding connecting rod 5.

[0020] In this embodiment, the bushing is placed on the feeding plate 1, which is inclined on one side of the transport mechanism. The bushing is pushed onto the transport mechanism by the pushing mechanism. When the bushing passes the pressure roller 7, it is blocked by the pressure roller 7. The bushing is pushed by the pushing assembly so that it passes through the pressure roller 7. The first spring 6 presses down on the pressure roller 7 so that the pressure roller 7 presses on the surface of the bushing. At the same time, by rotating the threaded rod 4, the height of the top plate 3 is limited, and the compression of the first spring 6 is changed, which indirectly changes the pressure of the pressure roller 7. When the bushing passes through the pressure roller 7, it is fixed by the pressure roller 7. It can only pass through the pressure roller 7 by being pushed by the next bushing, so that the bushings are closely arranged on the surface of the transport mechanism.

[0021] Furthermore, the transport mechanism includes two side plates 8, two drive wheels 9, a double-ribbed conveyor belt 10, and two baffles 11. The two drive wheels 9 are rotatably connected to the two side plates 8 and are located between the two side plates 8. The double-ribbed conveyor belt 10 covers the surface of the two drive wheels 9. The two baffles 11 are fixedly connected to the corresponding side plates 8 and are arranged opposite each other above the corresponding side plates 8.

[0022] In this embodiment, the bushing moves on the surface of the double-rib conveyor belt 10. Under the pressure of the pressure roller 7, the bushing and the double-rib conveyor belt 10 are pushed by the pushing component through the action of friction, and the two driving wheels 9 and the double-rib conveyor belt 10 rotate a certain distance accordingly.

[0023] Furthermore, the pushing mechanism includes a hydraulic cylinder 12 and a pushing component. The hydraulic cylinder 12 is disposed on one side of the transport mechanism, and the pushing component is fixedly connected to the hydraulic cylinder 12 and located at one end of the transport mechanism.

[0024] In this embodiment, the hydraulic cylinder 12 pushes the pushing component to move, the pushing component drives the bushing to move, the pushing component retracts, and the next bushing extends the feeding plate 1 to roll onto the surface of the double-rib conveyor belt 10.

[0025] Furthermore, the pushing component includes a fixed block 13, a sliding sleeve 14, and a second spring 15. The fixed block 13 is fixedly connected to the output end of the hydraulic cylinder 12 and is located on one side of the hydraulic cylinder 12. The second spring 15 covers the outside of the fixed block 13. The sliding sleeve 14 is slidably connected to the second spring 15 and is located on the outside of the fixed block 13.

[0026] In this embodiment, when the hydraulic cylinder 12 pushes, the fixed block 13 drives the sliding sleeve 14 to move, the sliding sleeve 14 pushes the bushing, and the second spring 15 contracts accordingly, so that the pressure of the sliding block on the bushing changes from small to large and then back to small.

[0027] Furthermore, the pushing component also includes a limiting rod 16, which is fixedly connected to the fixing block 13 and located inside the sliding sleeve 14.

[0028] In this embodiment, the limiting rod 16 restricts the retraction distance of the sliding sleeve 14.
