Description
Technical Field
The invention relates to a color changing box device of an embroidery machine, in particular to a color changing box for the embroidery machine, which reduces needle stopping errors.
Background
At present, in the industry of embroidery machines, the quantity of embroidery needles on the embroidery machines is increased, and the selection, working or not and needle stopping positions of the embroidery needles are controlled by a color changing box on the embroidery machine. The color changing cam on the existing color changing box is installed in an embedded mode in the installation process, namely the axial size of the color changing cam is matched with the distance between the left side face and the right side face of the box body of the color changing box, the matching is necessarily clearance fit, and the color changing cam always has axial movement in the rotating process. Because the traditional mode cannot be interference fit, once the interference fit inevitably causes the color changing cam to be incapable of rotating, axial movement under the clearance fit is always in the existing color changing box, and therefore the needle stopping position accuracy of the embroidery needle is directly influenced. How to improve the needle stopping precision of the embroidery needle under the control of the color changing box is always the object of research by the technical personnel in the field.
Disclosure of Invention
The invention provides the color changing box for the embroidery machine, which has the advantages of simple structure, zero axial clearance installation and multiple detection coordination and can reduce needle stopping errors.
The utility model provides a reduce embroidery machine of needle cutting error and use look case that trades, is including trading the look case box, installs motor drive's axial form in the box and trades the look cam, trades the look cam periphery and is equipped with the spiral cam groove, and the roller round pin of installing on the slider is connected in the cooperation of spiral cam groove, still installs the needle position on the inductor response needle position board on the slider, trade the look case box including integrative cast frame form casing, the frame form casing left and right sides limit is connected through thrust bearing respectively and is traded the look cam, trades look cam one end and is equipped with driven gear, the other end through thrust bearing butt installation tight top screw on frame form casing, tight top screw axial locking trades the look cam. This kind of trade look case structure is through setting up thrust bearing at trade look cam both ends, and the clearance formula embedding is installed in the frame form casing left and right sides limit, then utilizes the top screw structure with the frame form casing left and right sides limit with trade look cam, the axial clearance elimination of thrust bearing, realizes zero clearance assembly, has avoided trading look cam axial to move, certainly under the thrust bearing effect, trades the look camshaft and possesses efficient rotation performance simultaneously, has improved the needle position precision that stops of embroidery needle greatly.
The axial center of the color changing cam is provided with a through hole, a color changing cam shaft is arranged in the through hole, two ends of the color changing cam shaft extend out of the color changing cam and are sleeved with shaft sleeves, and the shaft sleeves are arranged on the box body of the color changing box; the top-tightening screw is connected with a thrust bearing through a flanging on the periphery of the shaft sleeve, and gaskets are arranged on two sides of the thrust bearing.
