Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 4The utility model provides an embodiment: an automatic rubber ring cutting device, comprising a cutting device 1, a feeding plate 2 is arranged on the inner wall of the cutting device 1, and the feeding plate 2 is controlled by an electric telescopic rod. The feeding plate 2 can push the feeding assembly 4 to move, so that the cut rubber ring can be ejected, thereby improving the feeding speed. A through groove 3 5 is provided on the right surface of the feeding plate 2, and the through groove 3 5 ensures that the feeding plate 2 can smoothly push the material down. A fixing assembly 3 is arranged on the right side of the inner wall of the cutting device 1 adjacent to the feeding plate 2, a limiting assembly 6 is arranged on the right end of the fixing assembly 3, and a feeding assembly 4 is arranged on the left end of the outer wall of the fixing assembly 3. The fixing assembly 3 includes a fixing cylinder 31, which is arranged on the left side of the inner wall of the cutting device 1, and a rotating rod 36 is rotatably connected to the right surface of the fixing cylinder 31. A round block 32 is fixedly connected to the left surface of the rotating rod 36. The round block 32 can facilitate workers to rotate the rotating rod 36. A through groove 1 310 is provided on the right surface of the round block 32, and an annular groove 39 is provided on the right surface of the fixing cylinder 31.

[0032] Reference Figure 2 - Figure 3 The material taking component 4 includes a push block 41, which is slidably connected to the outer wall of the fixed cylinder 31. A round rod 42 is slidably connected to the upper surface of the push block 41, and a fixed block 44 is fixedly connected to the lower surface of the round rod 42. The fixed block 44 is slidably connected to the upper surface of the arc plate 33. The curvature of the upper surface of the arc plate 33 fits the curvature of the lower surface of the fixed block 44 to ensure that the rubber ring can be evenly stressed.

[0033] Reference Figure 3 - Figure 4 The limit assembly 6 includes a push plate 61, which is slidably connected to the inner wall of the through groove 310. A spring 2 62 is fixedly connected to the right surface of the push plate 61. The spring 2 62 itself has a certain elasticity. It always pushes the push plate 61 to move to the left through its own elasticity, ensuring that the limit rod 63 is always in contact with the inner wall of the groove without pushing the push plate 61, thereby ensuring the stability of the limit. The right end of the spring 2 62 is fixedly connected to the inner wall of the through groove 310, and the left end of the push plate 61 slides on the inner wall of the annular groove 39.

[0034] Reference Figure 2 - Figure 3The inner wall of the fixed cylinder 31 is fixedly connected to a fixed plate 37, and a through groove 2 312 is provided on the right surface of the fixed plate 37. The through groove 2 312 can ensure that the connecting rod 34 can only move horizontally. The inner wall of the through groove 2 312 is slidably connected to the connecting rod 34, and a rectangular plate 35 is fixedly connected to the right surface of the connecting rod 34. The upper surface of the rectangular plate 35 is fixedly connected to an arc plate 33, and the arc plate 33 contacts the upper surface of the fixed cylinder 31. The rotating rod 36 penetrates and is rotatably connected to the right surface of the fixed plate 37. The arc plate 33 is arc-shaped, and the curvature of the outer wall of the arc plate 33 is the same as the curvature of the outer wall of the fixed cylinder 31, ensuring that the arc plate 33 can fit with the outer wall of the fixed cylinder 31 when merged, so that the rubber ring can be smoothly inserted into the outer wall of the fixed cylinder 31, and has the same curvature as the outer wall of the fixed cylinder 31.

[0035] Reference Figure 3 The inner wall of the fixed cylinder 31 is rotatably connected with a rotating plate 38 near the left side of the fixed plate 37. The right surface of the rotating plate 38 is fixedly connected to the left surface of the rotating rod 36. The left surface of the rotating plate 38 is provided with an arc-shaped through groove 311. The arc-shaped through groove 311 has a certain inclination angle. When the rotating plate 38 rotates, the connecting rod 34 will slide on the inner wall of the through groove 2 312 along the curvature of the arc-shaped through groove 311. In this way, the arc plate 33 can be moved to fix the rubber ring, and the connecting rod 34 is slidably connected to the inner wall of the arc-shaped through groove 311.

[0036] Reference Figure 3 A spring 43 is sleeved on the outer wall of the round rod 42. The spring 43 itself has a certain elasticity and always pushes the fixed block 44 downward to ensure the stability of the connection between the fixed block 44 and the arc plate 33. One end of the spring 43 is fixedly connected to the upper surface of the fixed block 44, and the other end of the spring 43 is fixedly connected to the inner wall of the push block 41.

[0037] Reference Figure 4 The front surface of the left end of the push plate 61 is fixedly connected to the limit rod 63. The inner wall of the annular groove 39 is provided with grooves in multiple groups. The annular groove 39 can ensure the sliding stability of the push plate 61. The front surface of the limit rod 63 contacts the inner wall of the groove.

[0038] Working principle: when in use, it is only necessary to put the unprocessed rubber sleeve on the outer wall of the fixed cylinder 31, and then push the push plate 61, the push plate 61 will squeeze the spring 2 62, and drive the limit rod 63 to move, so that the limit rod 63 is separated from the inner wall of the groove, then the round block 32 can be rotated, the round block 32 will drive the rotating rod 36 to rotate, and the rotating rod 36 will drive the rotating plate 38 to rotate. At this time, the connecting rod 34 will slide on the inner wall of the arc through groove 311 and slide on the inner wall of the through groove 2 312 along the curvature of the arc through groove 311, the connecting rod 34 will mobilize the rectangular plate 35 to move, the rectangular plate 35 will drive the arc plate 33 to move, and the multiple groups of arc plates 33 will squeeze the rubber ring from different directions, so that the rubber ring can be fixed, increasing practicality, and the push plate 61 can be loosened after the fixing is completed. At this time, the spring 2 62 will push the push plate 61 to move in the opposite direction through its own elasticity, and the limit rod 63 will move accordingly and insert into the inner wall of the groove, and the rubber ring can be processed.

[0039] After the processing is completed, you only need to start the equipment and push the push block 41 to move through the material-retrieving plate 2, which will cause the push block 41 to push off the rubber ring to complete the material-retrieving. When the arc plate 33 moves to fix the rubber, it will drive the fixing block 44 and the round rod 42 to move together. The fixing block 44 will squeeze the spring 43 to ensure that the material-retrieving component 4 fits the rubber ring to facilitate material-retrieving.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
