Description

The towel embroidery device of computer embroidering machine

Technical field:

The utility model relates to the embroidery equipment in the garment machinery, and particularly a kind of towel of realizing on computer embroidering machine is embroidered the new design of function.

Background technology:

Computer plain embroidery embroidery machine, be to carry out plain embroidery by predetermined pattern by computer control, it installs the punch block with many colo(u)r streaks embroidery pins above being embroidered lining, needle point is installed and the rotary shuttle mechanism of embroidering the pin cooperating below being embroidered lining down, is similar to Sewing machines, make and embroider line up and down and link, its operating efficiency is than the very big improve of hand embroidering, and rich color, but can only provide the plain embroidery needle tracking a kind of form.Embroider needle tracking if in the plain embroidery pattern, increase a part of towel, make the embroidery mask that third dimension be arranged, will make embroidery more attractive in appearance.

Summary of the invention:

The purpose of this utility model is to set up towel embroidery device in computer embroidering machine, to realize embroidery with multiple needle tracking shape.

Towel is embroidered and be need not to embroider line up and down and link, but requires to be embroidered lining with respect to embroidering the minimum with momentum of pin, can have a bit of embroidery line to stay the little wire loop of lining top formation because of lining frictional force hinders when pin is return so that embroider.In addition, towel is embroidered also should have selecting mechanism, to select the embroidery pin of different colo(u)r streaks.Feature of the present utility model is embroidered below, lining position and is installed and lining top plain embroidery structural similarity, transversely movable punch block down, and the shank that the variant colo(u)r streak in the following punch block is embroidered pin is fixed with the driving tongue respectively; With the axle rail that is with slide block is installed in the following head that following punch block is fixedlyed connected, wherein slip front be shaped on can with the groove that drives the tongue clutch, rear end and small rod (11) upper shaft connects, small rod (11) lower end and connecting rod (13) axle connects, the roller (17) of connecting rod (13) lower end be installed in lower main axis (15) on cam (14) on chute (14 ') rolling cooperate.Following punch block is fixedlyed connected with an end of pull bar, and the other end of pull bar is fixedlyed connected with the slide block that the needle selection roller that is had helical groove drives, and slide block axle upper and lower with it rail is slidingly matched.Pull bar is that two sections serial connections of adjustable length constitute.The small rod upper end and the slide block rear end axle of linkage connect, and lower end and connecting lever shape pitman shaft connect, and the roller of connecting lever shape connecting rod lower end is slidingly connected with the chute that is installed in the cam on the lower main axis.Driving tongue, the slide block of structure same as described above and the rail axle that is slidingly matched with it are installed on presser feet; One end of connecting rod is a fulcrum, and the other end connects by small rod and slide block axle, and the pitman shaft that the chute of middle part and eccentric cam is slidingly matched connects.The presser feet shaft is installed on the plain embroidery in the punch block.

The utility model utilizes the space of the plain embroidery machine side material level side of depositing, set up towel embroidery device by computer control operation, can be on common plain embroidery machine, provide towel to embroider stitching by layout, again because of many in the punch block of towel in the embroidering embroidery pins of collinear look not, many thread-color needle combinations with in the plain embroidery punch block make pattern color abundanter, and embroidery is more attractive in appearance.

The specific embodiment:

With reference to Fig. 1, embodiment is below the lining 6 of computer plain embroidery machine also is platen, corresponding to each plain embroidery head position, platen top, set up following punch block 1 with last punch block structural similarity, the not embroidery pin 5 of collinear look of the six roots of sensation is installed in it, embroider the pin needle point up for every, shank 3 tops separately respectively are fixed in its lower end, and shank 3 middle parts are installed shank and driven tongue 2.Fixedlying connected with pull bar 37 in punch block 1 back, can drive punch block and laterally move, and according to designing the six roots of sensation is embroidered required line look embroidery pin aligning pin hole center in the pin, seam is embroidered cloth 6, and the shape track is made X, Y two coordinates move by spending.Pull bar 37 and pull bar 37 ' be connected by helicitic texture, to adjust pull bar length.Pull bar 37 ' fixedly connected with the slide block 36 in being installed in colour changing case 28.Slide block 36 is placed in lower shaft rail 34,34 ' go up to constitute and is slidingly matched, and it laterally moves by the needle selection roller 33 that has helical groove and drives, and needle selection roller 33 is driven by needle selection roll shaft 31 by motor 29.

Above platen corresponding to each time punch block 1, the corresponding respectively presser feet 7 of installing, its effect is to push down lining not rise when wearing on a certain embroidery pin thereupon, all can be embroidered acupuncture with the lining that guarantees different densities and embroider, and the wire loop height that has also guaranteed to stay when embroidering pin returns the lining top is evenly consistent.

With reference to Fig. 2, Fig. 3, the driving tongue 2 that the motion of puncture up and down of embroidering pin 5 is driven by slide block 10 and is fixed on the shank 3 is realized.Slide block 10 is placed on the axle rail 9 that is contained in the head 8, its rear end and small rod 11 upper shafts company, and small rod lower end and 13 companies of connecting lever shape connecting rod, and do lever motion around the fulcrum 18 that is installed in bearing plate 12.Roller 17 is equipped with in connecting rod 13 lower ends, cooperates with eccentric groove 14 ' rollings on the cam 14 that driven by main shaft 15, and the rotary motion trace of cam 14 pumps driving tongue 2 by aforementioned link mechanism.Mark 4 is a colo(u)r streak among the figure, and line passes from embroider pin 5 centre bores.

Fig. 4 has represented the needle selection movement structure.Needle selection motor 29 by reducing gear from driving shaft 29 ' output torque, driving needle selection roll shaft 31 by meshing gear 32 rotates, needle selection roller 33 fixedly is placed on the roll shaft 31, have the helical groove of embroidering pin Position Design pitch by the six roots of sensation on it, roller 35 with pull bar slide block 36 in the groove is slidingly matched, when elected porcupine roller 33 rotated, groove driving slide block 36 drive pull bars 37 laterally moved to corresponding colo(u)r streak embroidery pin and are moved to needlework location.
