DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-7As shown, an automatic cutting device for producing rubber seals includes a base 1, a toggle mechanism 2 is rotatably connected to the right side of the upper end of the base 1, a hydraulic cylinder 3 is fixedly connected to the middle of the upper end of the base 1, a punching mechanism 5 is fixedly connected to the output end of the hydraulic cylinder 3, a blowing mechanism 4 is provided above the punching mechanism 5, a collecting mechanism 7 is fixedly connected to the middle of the upper end of the base 1, and a fixing mechanism 6 is slidably connected to the upper end of the base 1.

[0028] During the specific implementation of the above-mentioned device, the output end of the hydraulic cylinder 3 pushes the punching mechanism 5 downward to cooperate with the fixing mechanism 6 to cut the rubber sheet into a round rubber product. At the same time, when the output end of the hydraulic cylinder 3 drives the punching mechanism 5 upward, the punching mechanism 5 cooperates with the blowing mechanism 4 to make the round rubber product fall, and cooperates with the collecting mechanism 7 to collect it. At the same time, the toggle mechanism 2 cooperates with the fixing mechanism 6 and the punching mechanism 5 to push the rubber sheet to be cut forward, realizing automatic loading, cutting and collection. At the same time, after the final cutting is completed, the cut rubber waste can be directly removed for the next operation, and the cut round rubber product can also be taken out for subsequent operations.

[0029] See Figure 2 The upper end of the base 1 is symmetrically fixedly connected with a guide rail 11.

[0030] Specifically, when the above device is in operation, the guide rail 11 limits the overall moving path of the fixing mechanism 6 to prevent the fixing mechanism 6 from causing positional deviation when the entire rubber sheet to be cut is moved forward.

[0031] See Figure 2-4 The fixing mechanism 6 includes a slider 65 that is slidably connected to the outer surface of the guide rail 11. The upper end of the slider 65 is fixedly connected to a plurality of spring threes 64. The plurality of spring threes 64 are commonly fixedly connected to a pressure plate 62. The two pressure plates 62 are fixedly connected to a plurality of horizontal bars 63 at one end away from each other. The lower ends of the two pressure plates 62 are commonly clamped with a horizontal plate 61.

[0032] Specifically, during the operation of the above-mentioned device, by pulling the two pressure plates 62 upward, the plurality of springs 64 are stretched, and the rubber sheet to be cut is then spread flat on the upper end of the horizontal plate 61. Thereafter, the pressure plates 62 are no longer pulled, and the rubber sheet is fixed by the cooperation of the plurality of circular protrusions 621 and the circular grooves 612.

[0033] See Figure 4 A plurality of through holes 611 are provided at the upper end of the horizontal plate 61, and a plurality of circular grooves 612 are provided on the left and right sides of the upper end of the horizontal plate 61. A plurality of circular protrusions 621 are fixedly connected to the lower end of the pressure plate 62. The outer surface of the circular protrusion 621 is in close contact with the inner surface of the corresponding circular groove 612, and the lower end of the horizontal plate 61 is in close contact with the upper end of the collection shell 71.

[0034] Further, when fixing the rubber sheet to be cut, a number of springs three 64 jointly pull the pressing plate 62 downward. At the same time, the round bump 621 pushes the rubber sheet into the inner surface of the round groove 612, so that the whole rubber sheet is in a flat and straight state.

[0035] Refer to Figure 3 , the punching mechanism 5 includes a U-shaped plate 51 fixedly connected to the output end of the hydraulic cylinder 3. The vertical parts of the U-shaped plate 51 are fixedly connected with a fixing plate 52. A number of through holes three are opened at the upper end of the fixing plate 52. A round cutter 53 is fixedly connected to the inner surface of the number of through holes three. A push block 54 is fixedly connected to the upper right side of the horizontal part of the U-shaped plate 51. A dial rod 55 is fixedly connected to the upper end of the horizontal part of the U-shaped plate 51 on the right side of the push block 54.

[0036] During the operation of the above device, when the hydraulic cylinder 3 pushes the U-shaped plate 51 to drive the fixing plate 52 and the round cutter 53 to descend to the lowest point, the upper end of the push block 54 just contacts the lower end of the rectangular plate 41;

[0037] Specifically, during the operation of the above device, the output end of the hydraulic cylinder 3 pushes the U-shaped plate 51 downward, thereby driving a number of round cutters 53 and the fixing plate 52 to descend simultaneously. At the same time, the push block 54 and the dial rod 55 will also move in the same direction as the output end of the hydraulic cylinder 3, and then push the bottom end of the round cutter 53 to cut the rubber sheet.

[0038] Refer to Figure 7 , the air blowing mechanism 4 includes four springs two 42 fixedly connected to the upper right side upper part of the base 1. The lower ends of the four springs two 42 are jointly fixedly connected with a rectangular plate 41. A balloon 43 is fixedly connected to the upper right side upper part of the base 1. A conduit 44 is fixedly connected to the lower front side of the outer surface of the balloon 43. A number of output ends of the conduit 44 are arranged on the inner surface of the round cutter 53 adapted to it. The lower part of the outer surface of the balloon 43 is closely attached to the upper end of the rectangular plate 41.

[0039] Specifically, when the round cutter 53 finishes cutting, at this time, the output end of the hydraulic cylinder 3 drives the round cutter 53 and the fixing plate 52 to move upward. At this time, the upper end of the push block 54 pushes the rectangular plate 41 upward. Immediately, the rectangular plate 41 squeezes the balloon 43 upward. At this time, the air inside the balloon 43 is squeezed and released through the output end of the conduit 44, and then the circular rubber seal on the inner surface of the round cutter 53 is blown downwards.

[0040] Refer to Figure 3 , the collection mechanism 7 includes a collection shell 71 fixedly connected to the middle part of the upper end of the base 1. A sliding plate 72 is jointly slidably connected to the left side wall and the right side wall of the inner surface of the collection shell 71. A number of collection cylinders 73 are fixedly connected to the upper end of the sliding plate 72. A number of through holes two 711 are opened at the upper end of the collection shell 71.

[0041] When the cut circular rubber seal is blown downward by the air inside the conduit 44, the circular rubber seal will pass through the inner surface of the through hole 1 611 and the inner surface of the through hole 2 711 and fall into the inner surface of the collecting tube 73 that matches its position. When the cutting is completed, the slide 72 is pulled backward to drive several collecting tubes 73 to move backward at the same time. Then the cut circular rubber seal can be taken out from the inner surface of the collecting tube 73 and proceed to the next step.

[0042] See Figure 5 and Figure 6 The toggle mechanism 2 includes a circular plate 21 rotatably connected to the right side of the upper end of the base 1, and four toggle bars 22 are arranged in a circular array on the outer surface of the circular plate 21. A U-shaped groove 221 is provided on the left end of the toggle bar 22 near the side of the circular plate 21. The front side wall and the rear side wall of the inner surface of the U-shaped groove 221 are connected to a stopper 23 by rotation together. A spring 24 is fixedly connected to the right side wall of the inner surface of the U-shaped groove 221, and the other end of the spring 24 is fixedly connected to the stopper 23. The lower end of one toggle bar 22 is in close contact with the upper end of the toggle rod 55, and the front end of one toggle bar 22 is in close contact with the rear end of the horizontal bar 63.

[0043] Furthermore, when the circular cutter 53 finishes cutting and is driven upward by the hydraulic cylinder 3, the upper end of the lever 55 is in close contact with the lower end of a lever bar 22. When the lever 55 is driven upward, the lever bar 22 is moved. At the same time, the stopper 23 cooperates with the spring 1 24 to keep the upper end of the lever 55 in close contact with the lower end of the lever bar 22. When the lever 55 is moved upward, a lever bar 22 and the circular plate 21 are driven to rotate, and then the other lever bar 22 that is in close contact with a horizontal bar 63 on the right side pushes the horizontal bar 63 forward during the rotation process. Then the horizontal bar 63 drives the pressure plate 62, a plurality of springs 3 64, the horizontal plate 61, the fixed rubber sheet to be cut and the slider 65 to slide forward along the surface of the guide rail 11.

[0044] At this time, the lever 55 moves upward, thereby rotating the bar 22 to move the horizontal bar 63 forward until the front end of the next bar 22 is in close contact with the rear end of the next horizontal bar 63. At the same time, the distance moved by the horizontal bar 63 is equal to the length of the cutting blades 53.

[0045] Furthermore, when the output end of the hydraulic cylinder 3 drives the U-shaped plate 51, the circular cutter 53 and the lever 55 to cut downward again, the lower end of the lever 55 moves to the upper end of the lever bar 22 and wants to continue to move downward, pushing the block 23 to rotate counterclockwise while the spring 1 24 is stretched. At this time, the lever 55 slides downward along the outer surface of the block 23 to the lower end of the lever bar 22, and then the spring 1 24 wants to return to its original state, driving the block 23 to return to the inclined state, so that the next time the lever 55 moves upward, the lever bar 22 is pushed to rotate during the upward movement of the lever 55 through the cooperation with the U-shaped groove 221 and the lever bar 22.

[0046] Repeat the above operations until all the rubber sheets are cut. Then, pull up the two pressure plates 62, remove the cut waste corners, and perform subsequent collection and sorting. At the same time, pull the slide plate 72 backward to remove the circular rubber seal on the inner surface of the collection cylinder 73 for the next operation.

[0047] It should be particularly noted that the specific installation method of the hydraulic cylinder 3, the connection method of the circuit, and the control method adopted in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
