[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Embodiment 1:

When the rubber strip 7 is placed in the guide groove 21, the first guide wheel 412 and the second guide wheel 422 abut against the opposite sides of the rubber strip 7.

[0034] The guide motor 41 runs, driving the driving gear 411 and the first guide wheel 412 to rotate synchronously, and the driving gear 411 drives the matching gear 421 to rotate accordingly, and the matching gear 421 drives the second guide wheel 422 to rotate synchronously, and realizes the synchronous reverse rotation of the first guide wheel 412 and the second guide wheel 422, driving the rubber strip 7 to move forward under the action of friction.

[0035] like Figure 1 and 2 As shown, the cutting device also includes a balancing assembly 6, which includes a balancing block 61, a connecting rod 62 and a reset spring 63. Two matching blocks 32 are symmetrically fixedly connected to the fixed block 3, and two connecting rods 62 are provided. The two connecting rods 62 are both fixedly connected to the balancing block 61, and one end of the connecting rod 62 away from the balancing block 61 penetrates and extends into the matching block 32. After the connecting rod 62 passes through the matching block 32, a connecting nut 64 is threadedly connected to the connecting rod 62, so that the connecting rod 62 and the matching block 32 are always connected. The reset spring 63 is sleeved on the connecting rod 62, and one end of the reset spring 63 abuts against the balancing block 61, and the other end abuts against the fixed block 3 away from the connecting nut 64.

When the rubber strip 7 moves into the fixed groove 31, the cutting assembly 5 cooperates with the balancing assembly 6 to automatically cut the rubber strip 7. According to the preset PLC program, the driving motor 511 drives the driving cam 512 to rotate. When the large diameter end of the driving cam 512 abuts against the balancing block 61, the balancing block 61 drives the connecting rod 62 and the cutting knife 54 to move toward the fixed block 3 synchronously. The cutting knife 54 cuts the rubber strip 7 in sections through the cutting groove 33. At this time, the reset spring 63 is in a compressed state; when the driving cam 512 rotates to the small diameter end abutting against the balancing block 61, under the elastic force of the reset spring 63, the connecting rod 62, the balancing block 61 and the cutting knife 54 are driven to reset synchronously. Under the push of the subsequent rubber strip 7, the rubber strip 7 after cutting continues to move and moves out of the fixed block 3. This cycle is repeated to achieve automatic cutting.

[0040] Embodiment 2:

[0041] The difference between this embodiment and the first embodiment is that: Figure 3As shown, when the rubber strip 7 needs to be cut to a certain thickness, an appropriate cutting knife 54 is selected, and then the cutting knife 54 is connected to the connecting block 53. When the connecting block 53 is connected to the cutting link 52, the locking bolt and the locking nut are connected along the length direction of the rubber strip 7. Then, the balancing component 6 is connected to the fixing block 3. At this time, according to the setting of the PLC program, the large diameter end of the driving cam 512 is always in contact with the balancing block 61, and the operator cooperates with the guide component 4 to jointly drive the rubber strip 7 to move. During the movement of the rubber strip 7, it is always in contact with the cutting knife 54 to achieve automatic cutting in the thickness direction.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
