Sequin driving regulating mechanism

Abstract

The invention is driving and adapting mechanism for bead chip, which belongs to field of bead chip machine. It contains bead chip framework and conterminal electric motor. Upper end of deflector connects with motor shaft and lower end adapts to front fulcrum device. Corresponding position-setting seat and rackwork of deflector are set on bead chip framework. It is characterized in that the front fulcrum device contains front fulcrum seat and front fulcrum wiper. Set position-setting cant and oblique arm on two sides of front fulcrum seat, guide pore on center of front fulcrum wiper, bead chip driving fulcrum on front end and wiper oblique arm on brink. Front fulcrum passing guide pore is connected with front fulcrum seat for adapting by fix screw. Oblique arm of front fulcrum seat is crested to wiper oblique arm for adapting by fix screw. Positioning base of rackwork is fixed on bead chip framework. Positioning chip and positioning base adapt by elastic rotation. Positioning cant of positioning chip contacts positioning cant for adapting. The adapting mechanism is simple and fast, which can improve worked efficiency effectively. Its products have high percent of pass.

Description

technical field [0001] The invention belongs to the technical field of bead chip machines, in particular to a bead chip drive adjustment mechanism. Background technique [0002] Sequin machine is an additional device of computer embroidery machine, which is used to sew sequins on clothes, decorations, shoes and hats, curtains and other items. At present, sequin machines manufactured at home and abroad need to change the position by adjusting the front and rear fulcrums of the sequin machine and the blocking block of the lever when sewing different types of sequins, but the time required for debugging is too long. For example, when changing from 3mm sequins to 6mm sequins, based on 20 machine heads, first replace the sequin guide rails and reposition; adjust the position of the sequin cutter; adjust the center of the sequins and the position of the needle; adjust The starting point of the sequin lever is 0 degrees, and the motor shaft is initialize...

AI Technical Summary

Problems solved by technology

There are many parts to be debugged, and the positioning is not accurate. Some parts will be displaced during the debugging process, so repeated debugging is required. Due to repeated adjustments, parts often slip, which reduces work efficiency and wastes time and human resources. increased production costs

Due to the processing accuracy and design defects of some bead machines, after accurate debugging, there will be defects such as exposed pieces or scratches on the bead pieces, front fulcrum embossing, etc., resulting in unqualified products

Especially the 3mm diameter bead and 4mm bead, due to the small diameter, the accuracy of debugging needs to be high, and the debugging time also needs to be longer, which makes the factory unwilling to accept small batch orders
