Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a knife die for processing rubber products. Background Art

[0002] The knife die for rubber product molding and cutting is a device used to cut rubber products and promote the molding of rubber products. With the advancement of technology, people have higher requirements for the knife die for rubber product molding and cutting.

[0003] For example, the patent specification of the existing Chinese patent (publication number: CN206795987U) discloses a knife die for rubber product molding and cutting, which can be easily assembled and disassembled, so that it can be easy to carry, and the position of the blade can be easily adjusted, the structure is simple, and it is easy to use.

[0004] However, in the implementation of relevant technologies, it was found that the rubber product molding and cutting knife die designed above has the following problems: when the rubber product molding and cutting knife die is in use, it is easy to have the problem of knife body curling because it needs downward pressure to cut against the rubber product. Although the knife die can be disassembled and replaced when the knife body is damaged, it will undoubtedly increase unnecessary use costs, and frequent replacement of the knife body will also reduce production efficiency.

[0005] In view of this, a knife die for processing rubber products is provided to overcome the above-mentioned defects. Utility Model Content

[0015] The rubber product processing knife die designed by the utility model can make the rotating shaft drive the special-shaped gear to rotate by turning on the motor. In this process, the special-shaped gear will drive the transmission frame to drive the limit frame and the knife body to reciprocate along the direction set by the guide rod, so that the knife body can simulate the saw blade to cut the rubber product, thereby effectively alleviating the problem of knife body curling, thereby reducing the number of times the knife body is replaced, and indirectly improving production efficiency.

[0024] A rotating shaft 11 is rotatably arranged inside the fixed frame 1, the special-shaped gear 7 is fixedly sleeved on the rotating shaft 11, the driving shaft of the motor 9 is fixedly connected to one end of the rotating shaft 11, a cavity 12 and a sliding opening 13 are respectively provided inside and at the bottom of the fixed frame 1, the cavity 12 and the sliding opening 13 are communicated, both ends of the guide rod 4 are fixedly installed in the cavity 12, the rotating shaft 11 is rotatably connected to the rear wall of the cavity 12, and the connecting piece 10 is slidably inserted in the sliding opening 13.

[0025] During the specific implementation, firstly, the fixing frame 1, the limiting frame 2 and the cutter body 3 are moved downward and against the rubber product, and then the motor 9 is turned on to make the rotating shaft 11 drive the special-shaped gear 7 to rotate. During this process, the special-shaped gear 7 will first drive the transmission frame 5 to drive the limiting frame 2 and the cutter body 3 to move to one side along the direction set by the guide rod 4, and then when the special-shaped gear 7 rotates to the bottom, the transmission frame 5 can drive the limiting frame 2 and the cutter body 3 to move to the other side. This reciprocating process can make the cutter body 3 move back and forth to simulate the saw blade cutting the rubber product, thereby effectively alleviating the problem of curling of the cutter body 3, thereby reducing the number of times the cutter body 3 is replaced, and also indirectly improving the production efficiency.

[0026] As a further implementation of the above technical solution: the number of guide rods 4 is two, and the two guide rods 4 are symmetrically inserted in the transmission frame 5. By providing two guide rods 4, the sliding stability of the transmission frame 5 in the cavity 12 can be further improved, and the problem of the transmission frame 5 tilting can be avoided.

When a person sends a command to the remote controller 18 with a handheld mobile terminal, it will first be received by the signal receiver, and then the control unit will be operated to control the switch and operating status of the motor 9. Since the remote controller 18 belongs to the prior art, it will not be explained in detail in this manual.

[0031] Working principle:

[0032] When using the utility model, first connect the top of the fixing frame 1 to the cylinder driving end on the rubber product cutter, so that the fixing frame 1, the limiting frame 2 and the cutter body 3 can be moved up and down, and then the motor 9 and the remote controller 18 are connected to an external power supply. When it is necessary to cut the rubber product, first move the fixing frame 1, the limiting frame 2 and the cutter body 3 downward and against the rubber product, then turn on the motor 9, so that the rotating shaft 11 drives the special-shaped gear 7 to rotate. In this process, the special-shaped gear 7 will first drive the transmission frame 5 to drive the limiting frame 2 and the cutter body 3 to move to one side along the direction set by the guide rod 4, and then Later, when the special-shaped gear 7 rotates to the bottom, the transmission frame 5 can drive the limit frame 2 and the knife body 3 to move to the other side. The reciprocating movement of the knife body 3 can simulate the saw blade cutting the rubber product, thereby effectively alleviating the problem of the curling of the knife body 3, thereby reducing the number of times the knife body 3 is replaced, and the production efficiency is also improved indirectly. Since the knife body 3 will eventually be damaged no matter how the curling rate is reduced, the nut 17 is unscrewed from the positioning bolt 16 at this time, and then the positioning bolt 16 is unscrewed from the threaded hole 15, and the knife body 3 can be removed from the limit frame 2, thereby facilitating the replacement of the knife body 3.
