Abstract

The invention discloses a PVC (polyvinyl chloride) calender roller deflection signal processing device which comprises an X displacement signal acquisition circuit, a Y displacement signal acquisition circuit, a displacement signal processing circuit and a time delay circuit. Transverse and longitudinal displacement signals of PVC calender rollers can be acquired by laser sensors X1 and Y1 in the X displacement signal acquisition circuit and the Y displacement signal acquisition circuit, amplitude can be adjusted by a high-voltage step-down circuit and a low-voltage compensation circuit, then the transverse and longitudinal displacement signals can be filtered by an LC circuit, and voltages of the transverse and longitudinal displacement signals can be stabilized by a voltage stabilizer tube to be in the ranges of +5 V and +10 V. The PVC calender roller deflection signal processing device has the advantages that the shortcoming of nonlinear errors due to external disturbance can be overcome, the measurement accuracy can be improved, reliable on or off of MOS (metal oxide semiconductor) tubes T1-T4 can be guaranteed by the amplitude, and the accuracy of control signals can be improved; only simple logic judgment is carried out on the availability of transverse and longitudinal displacement deviation signals by a NAND gate circuit with the MOS tubes T1-T4 in the displacement signal processing circuit, the time is delayed by 5 S, determined high or low level can be outputted to a controller, accordingly, the PVC calender roller deflection signal processing device is fast in response and high in efficiency, deflection can be timely discovered and controlled, calendering effects can be guaranteed, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to a device for processing a deflection signal of a PVC calender roller. Background technique [0002] In the processing of PVC electrical tape, the PVC calender process is an important link, which requires high efficiency and precise work. This is a characteristic of the PVC calender, and the PVC calender needs to ensure that the tape cannot be skewed when it is working. Now The best way is to fine-tune the rollers, but the deflection is not easy to control in time, and it is often scrapped due to serious deflection, and a little deflection will affect the processing effect of the product. How to accurately and timely correct the deflection of the PVC calender roller and improve work efficiency is a must. At present, the technical problem of PVC calender has been studied, and it is also the purpose of researchers to continuously improve PVC calender. [0003] So the present inven...
