Abstract

The invention relates to an unreeling device of a cutting machine. The unreeling device comprises a support shaft, a transmission mechanism, an unfolding roller and a tension regulating mechanism, wherein the support shaft is arranged on a machine table and is used for supporting raw materials to realize rotating unreeling; the transmission mechanism is used for conveying the raw materials; the unfolding roller is positioned at the downstream of the transmission mechanism; and the tension regulating mechanism comprises a tension counter weight roller, a displacement sensor, a PLC and a variable-frequency motor for providing a power source for the unreeling conveyance. The tension counter weight roller is arranged in the transmission mechanism, and leather raw materials are also conveyed through the transmission by the tension counter weight roller. The tension counter weight roller can displace along with the tension change of the raw materials; a displacement sensor is used for sensing the displacement of the tension counter weight roller and outputting an analog signal corresponding to the displacement to the PLC; after the signal is received by the PLC and the calculation is performed, a control signal is output to the variable-frequency motor; and the frequency output of the variable-frequency motor is regulated, so that the output rotating speed of the motor and the integral linear velocity of the motor keep synchronous.

Description

technical field [0001] The invention relates to the field of artificial leather manufacturing, in particular to an unwinding device of an artificial leather cutting and inspection machine. Background technique [0002] The unwinding method of the existing artificial leather cutting and inspection machine is basically to place the leather on the machine table, and use the transmission of the multi-stage traction wheel to drive the leather to rotate and unwind. The hide is moved and conveyed downstream. [0003] In the existing way of pulling and driving leather raw materials through the rotation of the traction wheel, the pulling force generated by the leather itself will cause the leather to wrinkle at different positions during operation, and, in the entire circulation loop, This pulling force will be gradually transmitted and expanded. When this pulling force accumulates to a certain extent, it will affect or destroy the product quality, and even cause the product to be s...
