Abstract
A line-breakage sensor of knitting machine belongs to a line-breakage sensor of knitting machine. The sensor comprises a bracket and a switch which is equipped to the bracket. The bracket comprises a poking claw (2), a switch (3), a poking claw shaft (4) and a return spring (6); the poking claw is connected with the poking claw shaft; and the switch is positioned at the back end of the poking claw. The back end of the poking claw is connected with the return spring. Or the bracket is a fixed plate, and the switch is equipped to the fixed plate. The advantage of the invention consists in that the sensor can convert the mechanical signal of line-breakage of the knitting machine to the electric signal which is transmitted to a motor controller for controlling the motor to stop operating. The line-breakage sensor of knitting machine of the invention furthermore has the advantages of high sensitivity, excellent knitting effect of the knitting machine, increased product of knitting product, saved knitting material, reduced manufacturing cost of knitting machine, and saved space. The poking claw can be driven to rotate for a certain angle without large-load output of the spindle, and the component is not easily damaged in line-breakage stop.
Description
Technical field
The present invention relates to a kind of sensor, particularly a kind of line-breakage sensor of knitting machine.
Background technology
At present, a kind of line-breakage sensor that in braiding, uses, this line-breakage sensor includes brake lever axle, pusher dog cover, pusher dog seat, back stop and pusher dog; Pusher dog cover, pusher dog seat, back stop and pusher dog all are connected on the brake lever axle, and the pusher dog seat is installed on the lower wall, and the pusher dog cover is socketed on the brake lever axle; The pusher dog cover for seat is connected on outside the pusher dog cover; Pusher dog is connected pusher dog and puts, and is positioned at the upper end of pusher dog seat, and back stop is connected in the lower end fluting of brake lever axle and pusher dog cover; Be positioned at the below of lower wall, pusher dog is " people " font.
During work, behind the braiding machine spindle broken string, line weighs down the collision pusher dog; Pusher dog drives the brake lever axle and reverses certain angle, and the fluting of brake lever axle lower end also rotates an angle, and back stop is fixed; Back stop is deviate from the fluting of brake lever axle lower end; The brake lever axle is out of control and to lower slider, and the clutch that the brake lever axle after lower slider drives braiding machine comes off, and braiding machine is stopped.This mechanical switching device shortcoming: parking sensitivity is low, and the parts of fragile braiding machine influence weaving quality.
Summary of the invention
The objective of the invention is to provide a kind of: it is highly sensitive to stop, the line-breakage sensor of knitting machine of not fragile braiding machine parts.
The objective of the invention is to realize like this: this sensor comprises support and switch, and switch is rack-mount.
Described support comprises pusher dog (2), switch (3), pusher dog axle (4), back-moving spring (6), and pusher dog is connected on the pusher dog axle, and switch is positioned at the rear end of pusher dog; Rear end at pusher dog is connected with back-moving spring; Perhaps described support is a fixed head, and switch is installed on the fixed head.
There is connecting hole the centre of described pusher dog, and the front end of pusher dog is " people " font fork, and there is a groove rear end, and the both side ends in the rear end of pusher dog respectively connects a back-moving spring, and switch is positioned at the position of groove; Perhaps the front end of described pusher dog is an oblique protrusion, and there is a protrusion rear end, the diagonal angle setting of two protrusions; Perhaps two of front-end and back-end protrusions are arranged on the same side of pusher dog.
Described switch is near switch; It perhaps is microswitch; It perhaps is travel switch.
Beneficial effect: owing to adopt such scheme, braiding machine is when braiding process interrupt line, and the line bob of line-broken spindle can be run into pusher dog front end " people " font fork; It is that an angle is reversed in the axle center with the pusher dog axle that line-broken spindle drives pusher dog, and the boss cutting of pusher dog rear end is near the induction zone of switch or touch microswitch, just can in time collect the mechanical signal of line-broken spindle near switch or microswitch; And should mechanical signal be passed to electric machine controller; Motor quit work in control following moment of electric machine controller, and braiding machine runs out of steam the back with regard to automatic stopping, and it is highly sensitive to stop; Not fragile braiding machine parts have reached the object of the invention.
Advantage: this sensor can be transformed into the signal of telecommunication with the mechanical signal of braiding machine broken string, and signal of telecommunication three-way motor controller control motor quits work, and line-breaking stoppage is highly sensitive; Make the weave effect of braiding machine good, improved the quality of assembling-disassembling, practiced thrift braided material; Reduced the manufacturing cost of braiding machine simultaneously; Save the space, need not the big load output of spindle just can drive pusher dog and reverse certain angle, line-breaking stoppage is difficult for damaging parts.
