Description

A kind of industrial sewing machine with electronics tune needle gage

Technical field

The utility model relates to sewing device field, is specifically related to a kind of industrial sewing machine with electronics tune needle gage.

Background technology

The adjusting of flat seam machine needle gage at present adopts mechanical type more, realize needle gage variation, backstitch, encrypt joint function and all need different mechanisms to realize, and mechanism mostly is toggle, in the time that needle gage is larger, have trace and swing at the sewing machine lower link that runs up, send the sound of abnormal sound. While adjusting needle gage, need manual rotation stitch length knob dial plate, and that dial plate often designs is heavier, need larger strength just can make dial plate rotate, dial plate design can not well be locked, make the rotation of dial plate trace at the lower machine vibration that runs up, needle gage occurs unstable, and the variable quantity of needle gage is the scale performance of printing on Pictest dish simultaneously, it is larger, wayward that actual needle gage and display scale often differ; While backstitching, need to manually knock seam spanner down or use the realization of solenoid actuated needle pitch base to backstitch, both occur the problem that needle gage repeatability is poor, need to be by just reducing coincidence error to machinery adjustment for a long time; Sealing function needs backstitching spanner or electromagnet stroke limits, can not with backstitch function and use simultaneously.

Summary of the invention

The purpose of this utility model is in order to solve the weak point in above-mentioned background technology, a kind of industrial sewing machine with electronics tune needle gage is provided, it adopts step motor control, realizes electronics and adjusts needle gage, and electronics backstitches, electronic seal function, when adjustment needle gage, only need on operation panel, input the digital sewing that just can realize several millimeters of needle gages, fall along seam repeatability by touch-screen capable of regulating, can realize and backstitch the speed switching of closing close joint, structure is simpler, more convenient operation.

For achieving the above object, the technical solution adopted in the utility model is: a kind of industrial sewing machine with electronics tune needle gage, comprise sewing machine body, on the head of described sewing machine body, be provided with switch axle, it is characterized in that: on described switch axle, be arranged with switch axle sleeve, the stiff end bottom of the head of sewing machine body is provided with motor rack, on motor rack, be provided with stepper motor, on motor rack, be also provided with stopping means, described stopping means comprises left limit piece, right limit piece and fork, described left limit piece and right limit piece are arranged at respectively on motor rack, fork is fixed on switch axle sleeve by fastening nail, on switch axle sleeve, be arranged with synchronizing wheel I, the motion end of stepper motor is arranged with synchronizing wheel II, synchronizing wheel I is connected by Timing Belt with synchronizing wheel II.

Described switch axle is multidiameter.

Described stepper motor is connected with motor rack by screw.

Compared with prior art, advantage of the present utility model and effect are as follows:

1, the utility model adopts stepper motor can realize accurate control, cloth distance of the every rotation of stepper motor, the fixing synchronizing wheel I of front end will be rotated the angle of same implant distance, drive synchronizing wheel II to rotate by Timing Belt, thereby change amount of exercise and the direction of cloth feeding mechanism, realize needle gage and change, backstitch, add the functions such as close joint.

2, the utility model adopt toothed belt transmission, avoided gear or the crank mechanism abnormal sound problem under running up, needle gage is reliable, and work time fricton-tight, have gearratio accurately; Transmission efficiency is high, good energy-conserving effect.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is limit device structure schematic diagram;

Brief description of the drawings: 1-head, 2-switch axle, 3-synchronizing wheel I, 4-Timing Belt, 5-synchronizing wheel II, 6-motor rack, 7-stepper motor, 8-screw, 9-stopping means, 10-left limit piece, 11-right limit piece, 12-fork.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:

Referring to Fig. 1, a kind of industrial sewing machine with electronics tune needle gage, comprise sewing machine body, on the head 1 of described sewing machine body, be provided with switch axle, on described switch axle, be arranged with switch axle sleeve 2, the stiff end bottom of the head 1 of sewing machine body is provided with motor rack 6, on motor rack 6, be provided with stepper motor 7, described stepper motor 7 is connected with motor rack 6 by screw 8, on motor rack 6, be also provided with stopping means 9, described stopping means 9 comprises left limit piece 10, right limit piece 11 and fork 12, described left limit piece 10 and right limit piece 11 are arranged at respectively on motor rack 6, fork 12 is fixed on switch axle sleeve 2 by fastening nail, on switch axle sleeve 2, be arranged with synchronizing wheel I 3, the motion end of stepper motor 7 is arranged with synchronizing wheel II 5, synchronizing wheel I 3 is connected by Timing Belt 4 with synchronizing wheel II 5.

Described switch axle is multidiameter, and described transmission is toothed belt transmission.

The course of work of the present utility model:

When the utility model is just stitching, stepper motor 7 turns certain angle counterclockwise, the synchronizing wheel of motor shaft end drives switch axle to rotate certain angle with identical direction by Timing Belt 4, and now the direction of motion of cloth feeding mechanism is identical with the direction of motion of main shaft, and feeding is that forward feeding is just and stitches. The peak exercise of cloth feeding mechanism is the required maximum needle gage of sewing, and the angle being rotated counterclockwise by changing stepper motor, can realize the variation of needle gage while just seam.

While backstitching, stepper motor turns certain angle clockwise, the synchronizing wheel of motor shaft end drives switch axle to rotate certain angle with identical direction by Timing Belt, and now the direction of motion of cloth feeding mechanism is contrary with the direction of motion of main shaft, and feeding is that reverse feeding is and backstitches. The peak exercise of cloth feeding mechanism is the required maximum needle gage of sewing, and the angle turning clockwise by changing stepper motor, can realize the variation of needle gage while backstitching.

When just stitching or backstitching, when switch axle rotates to certain angle, stopping means can limit it and be further rotated, thereby plays certain protective effect.
