[0004] When cutting rubber, a worker will place the rubber on the rubber cutter, and then push the rubber so that one side of it moves directly under the cutting knife on the rubber cutter. During the process of pushing the rubber, if the force application point is not appropriate, the rubber will tilt while moving, which will affect the shape of the rubber after being cut. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that when the rubber is placed on the rubber cutting machine and the force application point is not appropriate during the process of pushing the rubber, the rubber will tilt while moving, which will affect the shape of the rubber after being cut.

[0007] In the above-mentioned rubber cutting machine, the rubber raw material can be automatically positioned during cutting, thereby avoiding displacement and misalignment during cutting.

[0008] As a further improvement of the present application, the first commutator and the second commutator are designed to mesh horizontally up and down.

[0009] As a further improvement of the present application, two clamping plates are symmetrically provided with slots at one end close to each other, and an extension plate is detachably connected to the slot.

[0010] As a further improvement of the present application, two screw holes are symmetrically drilled on the extension plate and the slot, and the two corresponding screw holes are fixed by bolt threads.

[0011] As another improvement of the present application, the card slot and the side end of the extension plate close to the card slot are both fixedly connected with magnetic sheets, and the two magnetic sheets attract each other.

[0012] As another improved supplement of the present application, the top end of the cutter is fixedly connected with a threaded shaft, the bottom end of the connecting shaft is cut with an inner groove, and the threaded shaft is engaged with the inner groove and fixed by a nut thread.

[0027] This solution can be achieved, when the cylinder 8 is turned on to drive the cutter 9 to cut the rubber raw material, it can be placed on the roller 3, and then the first electric push rod 6 is turned on to move the clamping plate 5 up and down to the position corresponding to the rubber raw material, and then the second electric push rod 20 is turned on to move the two clamping plates 5 closer to each other, so that the rubber raw material is clamped, and the clamping plate 5 clamps the tail of the rubber raw material, so the cutting is not affected during clamping. At this time, the motor 18 is turned on to drive the rotating shaft 14 to drive the roller 3 to rotate, and at the same time, the first commutator 15 and the second commutator 16 drive the lead screw 13 to rotate, so that the roller 3 drives the clamping plate 5 to move horizontally through the lead screw 13 during the movement of the raw material, so that the movement of the rubber raw material and the clamping plate 5 are consistent, which effectively achieves the effect of automatically positioning the rubber raw material during transportation and cutting, and avoiding offset and dislocation during cutting.

[0028] The second implementation method:

[0029] Figure 1-2 and Figure 6-7It is shown that two clamping plates 5 are symmetrically provided with a slot 21 near one end, and an extension plate 19 is detachably connected in the slot 21. Two screw holes are symmetrically drilled on the extension plate 19 and the slot 21, and the two corresponding screw holes are fixed by bolt threads.
