By providing the replacement structure 6, it is convenient to replace the cutting plate according to the rubber products of the cutting specifications required, so as to facilitate the cutting of various cutting products, avoid the situation that the whole device needs to be disassembled when replacing the cutting plate, and then facilitate the cutting of rubber products of various specifications. A limiting structure 7 is provided on the surface of the bottom plate 4, and by providing the limiting structure 7, it is convenient to clamp the rubber pad 5 tightly on the surface of the bottom plate 4, so that the rubber pad 5 is offset or detached from the bottom plate 4 during cutting, thereby improving the quality of cutting rubber products.
[0030] The specific settings and functions of the replacement structure 6 and the limiting structure 7 are described in detail below.
[0031] Reference Figure 2 and Figure 3 and Figure 4 As shown, in this embodiment: the replacement structure 6 includes a rectangular hole 61, which is opened on the surface of the pressure plate 3, and the inner wall of the rectangular hole 61 is slidably connected with a cutting plate 62, and both sides of the pressure plate 3 are slidably inserted with a latch 63, and both sides of the cutting plate 62 are opened with a circular groove 64, and the size of the latch 63 matches the size of the circular groove 64. The inner wall of the rectangular hole 61 is fixedly connected with a plurality of fixed rods 65, and the surfaces of the plurality of fixed rods 65 are sleeved with a cylinder 66. When the cutting plate 62 moves, it will slide along the surface of the cylinder 66, and when the cutting plate 62 moves, it will drive the cylinder 66 to rotate on the surface of the fixed rod 65. The cylinder 66 can reduce the friction between the cutting plate 62 and the inner wall of the rectangular hole 61, thereby facilitating the movement of the cutting plate 62. A groove 67 is provided at one end of the latch 63, and a ball 68 is rotatably connected to the inner wall of the groove 67. The latch 63 drives the ball 68 to fit on the surface of the cutting board 62 with the help of the contraction force of the spring 69. The ball 68 reduces the friction between the latch 63 and the cutting board 62, thereby avoiding the need to pull both latches 63 at the same time when pulling the cutting board 62. The arc surface of the latch 63 is covered with a spring 69, and the two ends of the spring 69 are respectively fixedly connected to the latch 63 and the pressure plate 3. The latch 63 is inserted into the circular groove 64 with the help of the contraction force of the spring 69. The spring 69 improves the stability of the latch 63 inserted into the circular groove 64 and avoids the latch 63 from coming out of the circular groove 64 due to shaking.
[0032] Reference Figure 5As shown, specifically, the limiting structure 7 includes two threaded rods 71, which are rotatably connected to the two sides of the bottom plate 4 respectively, and the surface of the threaded rod 71 is threadedly connected with a driving arm 72, and the surface of the driving arm 72 is fixedly connected with a limiting plate 73. One side of the limiting plate 73 is fixedly connected with two extension plates 74, and the surfaces of the two limiting plates 73 are slidably penetrated with round rods 75, which are fixedly connected to the surface of the bottom plate 4. When the limiting plate 73 moves, it will drive the extension plate 74 to slide along the surface of the round rod 75, and the round rod 75 can limit the moving path of the extension plate 74, thereby limiting the movement of the limiting plate 73, thereby preventing the limiting plate 73 from rotating when moving. A plurality of protrusions 76 are fixedly connected to the side of the limiting plate 73 close to the bottom plate 4, and the plurality of protrusions 76 are all conical, and the protrusions 76 will penetrate into the rubber pad 5, and the protrusions 76 can further improve the stability of the limiting plate 73 on the rubber pad 5.
[0033] Working principle: when it is necessary to cut rubber products of different specifications, the cutting plate 62 needs to be replaced. First, pull the latch 63. The latch 63 moves and slides in the pressure plate 3 and gradually comes out of the circular groove 64. The latch 63 will stretch the spring 69 when it moves. When the latch 63 comes out of the circular groove 64, the latch 63 is in a stretched state. Then pull the cutting plate 62. When the cutting plate 62 moves, release the latch 63. The latch 63 will use the contraction force of the spring 69 to drive the ball 68 to fit the surface of the cutting plate 62. The ball 68 reduces the friction between the latch 63 and the cutting plate 62, thereby avoiding the need to pull the two latches 63 at the same time when pulling the cutting plate 62, which further facilitates the replacement of the cutting plate 62. , the cutting plate 62 will gradually come out of the rectangular hole 61, and the cutting plate 62 will slide along the surface of the cylinder 66 when moving. The cutting plate 62 will drive the cylinder 66 to rotate on the surface of the fixing rod 65 when moving. The cylinder 66 can reduce the friction between the cutting plate 62 and the inner wall of the rectangular hole 61, thereby facilitating the movement of the cutting plate 62. When the cutting plate 62 comes out of the rectangular hole 61, the replaced cutting plate 62 is placed in the rectangular hole 61, and the latch 63 is pulled again. After the latch 63 moves to a suitable position, the cutting plate 62 is pushed so that the cutting plate 62 completely slides into the rectangular hole 61, and then the latch 63 is released. The latch 63 will be inserted into the circular groove 64 with the help of the contraction force of the spring 69, thereby restricting the replaced cutting plate 62 to the surface of the pressing plate 3.
[0034] When the locking cam 75 is in the locked state, the locking cam 73 is in the locked state, and the locking cam 73 is in the locked state, so that the locking cam 73 is in the locked state.
