Description

Sinker cover transmission mechanism

Technical Field

The invention belongs to the technical field of textile equipment, and particularly relates to a sinker cover transmission mechanism.

Background

The sinker cover is a component of the hosiery machine which provides a path for the motion trail of the sinker. The motion trail of the sinker is matched with the motion trail of the knitting needle to form a fabric loop, so that the fabric knitting is realized.

In the operation process of the hosiery machine, some cut yarn ends can be remained on the needle cylinder, most of the yarn ends can be sucked out through the air suction opening in the Hough disc, few yarn ends can be remained on the needle cylinder all the time, the needle cylinder is easy to block after a long time, therefore, the yarn ends need to be cleaned regularly, the motion mode of the sinker cover is controlled in a pneumatic mode at present, when the needle cylinder is seriously blocked, the rotation blocking phenomenon easily occurs between the needle cylinder and the sinker cover, and the equipment is easy to damage after a long time.

Disclosure of Invention

The invention aims to solve the technical problems, and provides a sinker cover transmission mechanism with detection and protection functions.

The purpose of the invention is realized as follows: the utility model provides a give birth to gram cover drive mechanism which characterized in that: comprises a transmission rack which is arc-shaped and is arranged on the outer wall of the sinker cover; the output shaft of the motor is arranged on the outer side of the sinker cover in an upward mode; the transmission gear is arranged on the output shaft of the motor and meshed with the transmission rack; the motor rotates forwards or backwards to drive the sinker cover to swing in the circumferential direction.

Through adopting above-mentioned technical scheme, because the machine is at the operation in-process, can remain some yarn heads of cutting on the cylinder, this yarn head majority can be sucked out through the inlet scoop on the huff dish, few part then can remain on the cylinder always, block up the cylinder easily after long-time, consequently need regularly clear up, the circumference swing of current sinker cover all adopts pneumatic mode to control, when the cylinder blocks up seriously, can't in time know, can only adopt the mode of regularly clearing up to handle, when the cylinder blocks up seriously, can influence the crochet hook on it, lead to equipment to produce the stifled firing pin that changes, serious still can hit bad cylinder. Therefore, the transmission mechanism is improved, and the motor is adopted to drive the transmission gear to rotate and drive the transmission rack connected to the sinker cover to rotate, so that the sinker cover is driven to rotate.

The invention is further configured to: the transmission mechanism further comprises a controller, wherein the controller comprises a detection module used for detecting the torque of the motor during movement, converting the signal and sending the signal to a PLC control module; the PLC control module is used for controlling the running state of the motor and changing the running state of the motor according to the torque signal sent by the detection module; when the torque signal detected by the detection module is greater than a preset threshold value, the PLC control module turns off the motor; the controller also comprises an alarm module which is electrically connected with the PLC control module, and when the torque signal detected by the detection module is greater than a preset threshold value, the PLC control module starts the alarm module to make the alarm module give an alarm sound.

Through adopting above-mentioned technical scheme, for the effect that can play the police dispatch newspaper, be provided with detection module and the alarm module who is used for detecting motor torque for this reason, when motor torque crescent reaches and surpasss and predetermine the threshold value, the surface cylinder has been blockked up, closes the motor through PLC control module this moment to start alarm module, make it send the alarm sound, thereby remind the staff, in time inspect the maintenance to the machine.

The invention has the beneficial effects that:

1. the transmission mechanism is improved, and the motor is adopted to drive the transmission gear to rotate and drive the transmission rack connected to the sinker cover to rotate, so that the sinker cover is driven to rotate.
