[0011] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below by combining with specific implementation manners and referring to the drawings. It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0012] DETAILED DESCRIPTION: in combination with Figures 1-2As shown, a novel rubber cutting device, including a belt conveyor 1, one end of the belt conveyor 1 is provided with a backing plate 5, the backing plate 5 is provided with a plurality of notches 51 away from one side of the belt conveyor 1, the top view of the notch 51 is rectangular, the top surface of the backing plate 5 is in the same plane with the top surface of the belt on the belt conveyor 1, the upper side of the belt conveyor 1 is provided with a press roller 11 near one end of the backing plate 5, the press roller 11 can press the rubber sheet on the belt conveyor 1, so that the rubber sheet is not easy to slip relative to the belt conveyor 1, improve the reliability of feeding, the size of the backing plate 5 in the length direction of the belt conveyor 1 is as small as possible, in order to reduce the friction between it and the rubber sheet, so that the rubber sheet is more easy to advance, and the distance between the notch 51 and the press roller 11 is also relatively close, the end of the belt conveyor 1 provided with the backing plate 5 is also provided with a rack 3, the rack 3 is rotatably connected with a cutting knife group 4, the cutting knife group 4 is drivingly connected with a first motor, the cutting knife group 4 includes a center shaft, preferably the axis of the center shaft is in the same plane with the upper surface of the backing plate 5 or a little higher than the plane where the upper surface of the backing plate 5 is, the center shaft is provided with a plurality of disc-shaped longitudinal cutter 41, the blade on the outer circumference of the plurality of longitudinal cutter 41 is respectively located in the plurality of notch 51, the thickness of the longitudinal cutter 41 is as thin as possible, the adjacent longitudinal cutter 41 is provided with a transverse cutter 42, when the transverse cutter 42 cuts the rubber sheet, it will not collide with the backing plate 5 and the distance between them at this time is as small as possible, the lower side of the cutting knife group 4 is provided with a collecting box 2, the upper part of the collecting box 2 is open. Figure 1 As shown, the rubber sheet to be cut is placed on the belt conveyor 1 and conveyed to the right, when its right end contacts with the blade of the counterclockwise rotating longitudinal cutter 41, the right end of the rubber sheet is cut into a plurality of longitudinal notches to form a rubber strip, when the transverse cutter 42 rotates to the upper surface of the rubber strip to cut it transversely, the right end of the rubber strip has already stretched out a certain distance to the right, so the rubber strip can be cut into rubber blocks. The linear speed of the blade of the longitudinal cutter 41 is much greater than the advancing speed of the rubber sheet, and the cutting speed of the transverse cutter 42 is also fast (in order to make the transverse cutter 42 achieve a faster cutting speed, only one transverse cutter 42 is arranged between the adjacent two longitudinal cutters 41, and the transverse cutter 42 is relatively far away from the center shaft), so that the distance of the rubber sheet advancing at the moment of transverse cutting is very small. Under the action of centrifugal force and gravity, the rubber blocks fly out of the cutting knife group 4 and fall into the collecting box 2.

[0013] The blade of the transverse cutter 42 is gradually inclined to the rear of its rotating direction in the direction from one end to the other end, so that the cutting force required by the transverse cutter 42 is smaller.

[0014] The outer surface of the transverse cutter 42 is on the virtual circumferential surface coaxial with the center shaft, and the virtual circumferential surface is very close to the end of the backing plate 5 away from the belt conveyor 1, so that the rubber strip can be easily cut off.

[0015] In order to make the front end of the rubber sheet easy to enter the lower part of the compression roller 11, a gear can be arranged at one end of the driving roller of the belt conveyor 1, and a gear meshing with the gear is arranged at one end of the compression roller 11, so that the compression roller 11 can be driven to rotate and be opposite to the clockwise direction of the belt conveyor 1.

[0016] The embodiments of the specific embodiment are the preferred embodiments of the utility model, not limited to the protection scope of the utility model, so: all equivalent changes made according to the structure, shape, principle of the utility model should be covered in the protection scope of the utility model.
