Abstract

The invention relates to a high-speed towel embroidery machine head. The existing towel embroidery machine head adopts a driving mechanism to drive a pipe nozzle rod, a towel needle rod and a foot bar to do reciprocating movement, and the driving mechanism is realized by the cooperation of a cam with a sealed slide groove and a swing rod; a roller is arranged at one end of the swing rod and is arranged in the slide groove of the cam in a matching way; when the cam rotates, the roller at the end part of the swing rod is moved in the slide groove of the cam to drive the other end of the swing rod to swing, and then the pipe nozzle rod, the towel needle rod and the foot bar are driven to do the reciprocating movement; because the roller is arranged in the slide groove of the cam in a matching way, the diameter of the roller needs to be smaller than the width of the slide groove; obviously, when the cam rotates, the roller can rotate and roll in the slide groove of the cam at several dozens of speed, then the heating and abrasion of the roller are easily caused, the roller is even discarded, and the existing towel embroidery machine head is difficult to break the technical bottleneck of 650rpm speed, thereby greatly limiting the working efficiency of the towel embroidery machine head. The high-speed towel embroidery machine head has the advantage that the working efficiency is greatly improved.

Description

High speed chenille embroidery machine head
Technical field
The present invention relates to a kind of embroidering machine head, be specifically related to a kind of chenille embroidery machine head.
Background technology
The chenille embroidery machine head used at present, the driving mechanism of the cam and fork cooperation that adopt band to close chute drives ozzle bar, towel shank and presser bar to pump, one end of fork is provided with the roller that can be engaged in cam channel, when cam rotates, the roller of swing link end part is mobile in cam channel makes the fork other end swing, thus ozzle bar, towel shank and presser bar are pumped.Because roller is engaged in cam channel, therefore the diameter of roller must be less than the width of chute.Obviously, when cam rotates, roller will roll with the speed rotation of decades of times in cam channel, very easily cause roller to generate heat to wear and tear, even scrap, cause existing towel embroidery machine speed to be difficult to the technical bottleneck of breakthrough 650 revs/min, thus significantly limit the operating efficiency of towel embroidery machine.
Summary of the invention
The object of this invention is to provide one can significantly increase work efficiency, the high speed chenille embroidery machine head of longer service life.
For achieving the above object, the present invention adopts following technical scheme: a kind of high speed chenille embroidery machine head, comprise casing, ozzle is provided with in described casing, lower end is provided with the towel shank of towel pin, lower end is provided with presser bar and the driving mechanism of presser feet, driving mechanism can make ozzle, presser feet and towel pin pump, described ozzle is located at the lower end of ozzle bar, described ozzle bar, towel shank and the spaced setting of presser bar, described driving mechanism comprises the first cam, second cam, 3rd cam and linkage, described first cam, second cam and the 3rd cam all rotatable, described linkage comprises the first connecting rod mechanism be connected with ozzle bar, the second connecting rod mechanism be connected with towel shank, the third connecting rod mechanism be connected with presser bar, the collocation of described first connecting rod mechanism has the first roller, described first roller can offset with the first cam outer rim upper surface, and the first roller and first connecting rod mechanism link, the collocation of described second connecting rod mechanism has the second roller, described second roller can offset with the second cam outer rim upper surface, and the second roller and second connecting rod mechanism link, the collocation of described third connecting rod mechanism has the 3rd roller, described 3rd roller can offset with the 3rd cam outer rim upper surface, and the 3rd roller and third connecting rod mechanism link, described first cam rotates and the first roller can be made to move up and down, described second cam rotates and the second roller can be made to move up and down, described 3rd cam rotates and the 3rd roller can be made to move up and down.
The present invention is coordinated with the outer rim of cam by the roller on linkage, thus suitably can increase the size of roller, when cam rotates, the number of turns of roller rotation can ensure with cam turning collar number basically identical, thus greatly reduce the friction of roller, and then the rotating speed of cam can be improved and improve operating efficiency and the service life of chenille embroidery machine head, make the operating rate of the head of towel embroidery machine of the present invention reach more than 1000 revs/min; In addition, the present invention adopts linkage, and towel is for answering one group of connecting rod, the corresponding one group of connecting rod of ozzle, the corresponding one group of connecting rod of presser feet, instead of adopt cam to coordinate driving mechanism with fork, take up room little, and precision of the present invention can be made higher, the towel embroidery quality woven is better.If ozzle bar is set in outside towel shank, carrying out adding the concentric problem that ozzle bar and towel shank are considered in man-hour requirement, towel shank of the present invention, ozzle bar and presser bar are spaced, ozzle bar is not set on towel shank, make structure of the present invention simpler, be convenient to processing and assembling, precision is also higher.The present invention adopts linkage, during linkage power transmission, wearing and tearing are few, be easy to keep precision, and roller is easy to wear in cam structure, and the chute of cam (profile) bad processing, excesssive gap between easy generation roller and chute or too small problem, excesssive gap can produce larger noise, and gap is too small, and roller not easily puts into chute.
As preferably, described first roller, second roller and the 3rd roller are bearing, describedly be provided with the first cam, second cam and the 3rd cam are fixed on camshaft, described camshaft is fixed in casing relatively, and described camshaft is rotatable, the vertical guide post arranged is provided with in described casing, described guide post is provided with top shoe and sliding block, described top shoe is positioned at the top of sliding block, and top shoe and sliding block all can move axially along guide post, described guide post is arranged with the first spring and the second spring, first spring is between top shoe and sliding block, and the two ends of the first spring offset with top shoe and sliding block respectively, described second spring is positioned at the top of top shoe, lower end and the sliding block of the second spring offset, the upper end of the second spring can be compacted, the outside of described top shoe is formed with the right plate upwards extended, the outside of described sliding block is formed with the left plate upwards extended, described left plate and right plate are oppositely arranged on the relative both sides of guide post, described first roller is axially fixed in the top of left plate, described second roller is axially fixed in the top of right plate,
