DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0017] like Figure 1-3 As shown, the utility model provides a rubber sheet cutting device for a rubber sheet cooling machine, including a mounting seat 6, a clamping mechanism is arranged on the mounting seat 6, the clamping mechanism includes a clamping plate 9, both ends of the clamping plate 9 are fixedly connected to a sliding seat 8, and a first ball linear slide 4 matched with the sliding seat 8 is arranged on the mounting seat 6. The middle part of the clamping plate 9 is fixedly connected to a cylinder 2 through a cylinder connector 3, which is used to push the clamping plate 9 to move along the first ball linear slide 4.

[0018] A shearing mechanism is provided on the side of the mounting seat 6 opposite to the clamping plate 9, and the shearing mechanism includes a reduction motor 1, and the reduction motor 1 is fixed to the mounting seat 6 through a motor mounting plate 16. A driving pulley 12 is fixedly connected to the output shaft of the reduction motor 1, and a driven pulley 11 is provided on the side of the mounting seat 6 opposite to the reduction motor 1, and the driven pulley 11 and the driving pulley 12 are driven by chain meshing. A blade mounting plate 13 is fixedly connected to the chain, and a disc blade 10 is fixedly provided on the blade mounting plate 13, and a knife groove 18 matching the disc blade 10 is provided on the clamping plate 9.

[0019] The bottom of the blade mounting plate 13 is provided with a second ball linear slide rail 7 for sliding cooperation, which provides rigid support for the blade mounting plate 13 to prevent the flexibility of the chain itself from failing to provide sufficient support for the disc blade 10. Both ends of the second ball linear slide rail 7 are provided with proximity switches 5, which are fixed to the second ball linear slide rail 7 through proximity switch brackets 15. The blade mounting plate 13 is also provided with a sensing plate 14 for triggering the proximity switch 5.

[0020] A chain baffle 17 is also provided outside the chain to protect the shearing mechanism.

[0021] When in use, the rubber film is vertically placed between the clamping plate 9 and the chain baffle 17, and the cylinder 2 pushes the clamping plate 9 to move along the first ball linear slide 4 until the clamping plate 9 rests on the chain baffle 17, clamping the rubber film, and the disc blade 10 enters the knife groove 18; the reduction motor 1 drives the active pulley 12 to rotate, and the chain drives the blade mounting plate 13 to move along the second ball linear slide 7. When the proximity switch 5 detects the induction plate 14, the reduction motor 1 is controlled to reverse, so that the disc blade 10 reciprocates and cuts the rubber film multiple times.

[0022] When the blade direction of the disc blade 10 becomes blunt due to the number of times of use, it can be rotated to an angle and then continue to shear. A disc blade 10 can be rotated four times before sharpening, thereby improving the utilization rate of spare parts.

[0023] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
