DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] See also Figure 1-6The utility model provides a technical solution: a cutting device for producing a sealing ring, including a base 1, a conveyor belt 2, a top plate 3, a cylinder 4, a connecting plate 5, an outer blade 6, an inner blade 7, a push block 8, a telescopic rod 9, a spring 10, a guide rail 11, a pressure roller 12, a gear 13, a gear 2 14, a connecting block 15, and a connecting rope 16.

[0031] This device has the effect of preventing the rubber block from shifting, specifically:

[0032] The surface of the conveyor belt 2 is provided with a pressing structure, which uses a pressing roller 12 to fix the rubber block and smooth the rubber block from the middle to both sides. The pressing structure includes a guide rail 11, which is an arc-shaped L-track. One end of the guide rail 11 is fixedly installed on the column on the upper surface of the base 1. Two guide rails 11 are symmetrically arranged on both sides of the conveyor belt 2. A pressing roller 12 is connected between the two guide rails 11. The pressing roller 12 slides on the surface of the guide rail 11 and is rotatably connected. A gear 13 is rotatably installed on the surface of the guide rail 11, and a gear 2 14 is rotatably installed on the surface of the base 1. Gear 1 The sides of gear 13 and gear 2 14 are respectively meshed with racks, and the racks at gear 1 13 and gear 2 14 are connected to the surface of the same connecting block 15, and the connecting block 15 is connected to the connecting plate 5 through a connecting rod. The surfaces of the base 1 and the top plate 3 are both provided with grooves to accommodate the racks on the surface of the connecting block 15, and the upper surface of the pressing roller 12 is provided with a connecting rope 16 connected to the rotating shaft of gear 2 14, and the lower surface of the pressing roller 12 is provided with another connecting rope 16 connected to the rotating shaft of the pressing roller 12. The surface of the conveyor belt 2 is symmetrically provided with the same pressing rollers 12, and the structures at the pressing rollers 12 are exactly the same;

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rubber block to be cut is placed on the surface of the transmission belt 2, the transmission belt 2 is started, and the rubber block moves to the right along the conveyor belt 2 until it is directly below the cylinder 4, and the cylinder 4 is started to cut the rubber block. When the cylinder 4 drives the connecting plate 5 to move downward to cut the rubber block, the connecting plate 5 will also drive the connecting blocks 15 on both sides to move downward. The structure at the pressure roller 12 is completely the same. Taking the left pressure roller 12 as an example, when the connecting plate 5 moves downward, the connecting plate 5 drives the connecting block 15 to move downward, and the connecting block 15 moves downward to drive the rack on the lower surface to move downward, and the rack drives the gear 13 to rotate. When the gear 13 rotates, it drives the connecting rope 16 to wrap around the surface of the rotating shaft. The rollers 12 on the left side move toward each other when the cylinder 4 descends, and the rollers 12 on the other side move to the right on the surface of the guide rail 11. The rollers 12 on both sides move in opposite directions, smoothing the rubber block from the middle to both sides while pressing the rubber block to prevent displacement of the rubber block. When the cutting is completed and the connecting plate 5 rises, the connecting block 15 rises accordingly, and the connecting block 15 drives the rack on the upper surface to move upward, driving the gear 2 14 to rotate. The rotation of the gear 2 14 drives the connecting rope 16 on the upper surface of the roller 12 to move, so that the roller 12 moves in the opposite direction and returns to its original position.

[0034] This device has the effect of preventing the rubber block from sticking, specifically:

[0035] A conveyor belt 2 is arranged on the upper surface of the base 1, a top plate 3 is installed above the base 1 through a support, a cylinder 4 is arranged on the surface of the top plate 3, a connecting plate 5 is arranged on the lower surface of the cylinder 4, an outer blade 6 is arranged on the lower surface of the connecting plate 5, and the outer blade 6 is a circular ring structure. An inner blade 7 is arranged on the lower surface of the connecting plate 5, and the inner blade 7 is also a circular ring structure, and the outer blade 6 and the inner blade 7 form a concentric circle structure, and a pusher structure is arranged on the side of the outer blade 6 and the inner blade 7, and the pusher structure uses the movement of the pusher block 8 to push the rubber The block moves, and the pushing structure includes a pushing block 8. A telescopic rod 9 is arranged on the upper surface of the pushing block 8, and the other end of the telescopic rod 9 is fixed to the lower surface of the connecting plate 5. A spring 10 is arranged on the outer surface of the pushing block 8, and one end of the spring 10 is fixed to the lower surface of the connecting plate 5, and the other end of the spring 10 is fixed to the surface of the pushing block 8. There are 5 pushing blocks 8, one of which is arranged on the inner circle of the inner blade 7, and the other 4 pushing blocks 8 are distributed in an annular manner between the outer blade 6 and the inner blade 7. The lower end of the pushing block 8 is longer than the outer blade 6 and the inner blade 7;

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, after the pressure roller 12 presses the rubber block, the connecting plate 5 descends under the drive of the cylinder 4. The descent of the connecting plate 5 drives the outer blade 6 and the inner blade 7 on the lower surface to descend, and the push block 8 descends with the connecting plate 5. The push block 8 first contacts the rubber block. Under the continuous pressure of the cylinder 4, the push block 8 compresses the telescopic rod 9 and the spring 10 upward. At this time, the outer blade 6 and the inner blade 7 contact the rubber block and cut the rubber block. After the cutting is completed, the cylinder 4 drives the connecting plate 5 to rise, and the outer blade 6 and the inner blade 7 rise at the same time. After the push block 8 loses the pressure of the cylinder 4, it rebounds downward under the action of the spring 10, and the push block 8 pushes the rubber block downward, so that the rubber block is separated from the outer blade 6 and the inner blade 7 to prevent the rubber block from adhering to the blades.

[0037] Working principle: When the cutting equipment produced by the sealing ring is used, the cylinder 4 is started, and the cylinder 4 drives the connecting plate 5 to move. When the connecting plate 5 moves, it drives the connecting block 15 to move synchronously, thereby driving the gear 13 to rotate, so that the pressure roller 12 moves, and the pressure rollers 12 on both sides move synchronously, from the middle of the rubber block to both sides, so that the rubber block is smoothed from the middle to both sides, to prevent the unevenness of the rubber block from affecting the cutting during the pressing process of the rubber block, the connecting plate 5 drives the outer blade 6 and the inner blade 7 to move to cut the rubber block, and push blocks 8 are provided at the outer blade 6 and the inner blade 7. When the blade descends to cut the rubber block, the push block 8 is compressed by pressure. When the cutting is completed and the blade is recovered, the push block 8 rebounds under the action of the spring 10, and exerts a force on the cut rubber block to prevent the rubber block from adhering to the blade, thereby increasing the overall practicality.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
