Driving means for combing machine nipper

Abstract

The invention discloses a driving device for a combing machine nipper. Including nipper, nipper pendulum shaft, three-position four-way proportional solenoid valve, two-way quantitative hydraulic motor, coarse filter, one-way variable hydraulic pump, safety overflow valve, one-way valve, throttle valve, servo motor, speed sensor and transmission control system. The above-mentioned execution component is driven by the servo motor under the control of the transmission control system through the open hydraulic system to drive the nipper pendulum shaft to make the nipper move according to the predetermined curve rule, thus constituting the driving device of the comber nipper. The invention adopts the combination scheme of the transmission control system and the open hydraulic system to improve the quick response capability of the nipper drive device of the combing machine, thereby improving the movement accuracy and efficiency of the nipper part of the combing machine.

Description

technical field [0001] The invention relates to textile machinery equipment, in particular to a driving device for a combing machine nipper. Background technique [0002] The traditional combing machine nipper transmission device is composed of two sets of four-bar linkage mechanisms, the crank slider linkage mechanism and the rocker linkage mechanism. There are many meshing points in the movement, and the precision is poor. The parts of the mechanism require high precision in manufacturing and installation, and it is difficult to adapt to high-speed reciprocating rotation. For the spinning process of various cotton fibers, its applicability and versatility are poor. . At present, the new servo motor drives the driving device of the comber nipper, although the mechanical transmission structure with complex structure is eliminated, but due to the large load inertia of the nipper part, the servo motor needs to transmit a large torque and consumes a lot of power, while the com...
