[0027] S2: The coiled material after trimming is moved under the cutter assembly for strip cutting preparation.

[0028] S3: Meanwhile, the moving plate moves, and one row of the pin insert 10 pre-presses and positions the coiled material.

[0029] S4: The cutter assembly works to cut the coiled material into strips.

[0030] S5: The rubber material is moved and conveyed to the weighing assembly by the feeding assembly for weighing.

[0031] S6: During the weighing process, the moving plate resets to the cutter assembly and pre-presses the next coiled material.

[0032] S7: The weighed rubber strip is moved to the conveyor belt 2 by the pin insert 10 in the other row of the moving plate.

[0033] The coiled material is trimmed and cut to the specified length by the trimming wheels 3 and moved under the cutter assembly. Through the two rows of pin inserts 10 on the moving plate, one row pre-presses the end of the coiled material. Meanwhile, the other row corresponds to the weighing assembly and realizes synchronous lifting through the moving plate.

[0034] Similarly, after the coil stock is cut into strips and moved onto the weighing component, and the weighing rubber strip is moved onto the conveyor belt 2, these operations can be carried out synchronously.

[0035] Preferably, the two roller shafts 5 are arranged in an up-and-down structure inside the frame 1, and the coil stock after trimming and cutting is moved through between the two roller shafts 5 into the cutter assembly.
