[0031] Here’s how it works:

[0032] The semi-finished rubber block squeezed by the press is conveyed to the weighing mechanism 34 of the material transfer roller line 321 in the rubber cutting and weight reduction equipment 3. The system determines the value exceeding the specified weight range. According to the weight, the material transfer mechanism 32 clamps the semi-finished rubber block and moves and controls the cutting position under the drive of the material transfer servo motor 322. Then the guillotine electric cylinder 312 of the guillotine mechanism 31 controls the guillotine blade beam 3 to move downward to cut off the semi-finished rubber block for rough weight reduction, and the cut part falls freely. The semi-finished rubber block after rough weight reduction is then judged by the weighing mechanism 34 to determine the value exceeding the specified weight range after rough weight reduction. value, the semi-finished rubber block is transported to the fine weight reduction mechanism 33, the fine weight reduction mechanism 33 drives the upper fine weight reduction knife 3344 and the lower fine weight reduction knife 3346 to move towards each other to extrude and cut the rubber through the upper fine weight reduction push knife cylinder 3343 and the lower fine weight reduction push knife cylinder 3345, the cutting depth is controlled by the fine weight reduction feed servo motor 331, the removal amount is controlled, so that the semi-finished rubber block reaches the specified weight range, after the cutting is completed, the upper fine weight reduction knife 3344 and the lower fine weight reduction knife 3346 are opened, and the ejector rod 3347 in the lower fine weight reduction knife 3346 ejects the cut material under the action of the ejector cylinder 3348.

[0033] The calculation method used is as follows:

[0034] According to the known excess weight G (kg), the rubber density ρ (kg / m 3 ). The volume V can be calculated using the following formula

[0035] V=G / ρ

[0036] Roughly reduce the weight and then calculate the cutting position X (m) based on the volume V using the following formula:

[0037] X=V / (A*B)

[0038] Precise weight reduction can then achieve precise control of product weight by controlling the feed amount.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
