Abstract

The utility model relates to a yarn clamping device for controlling yarns in a yarn feeding system of a hosiery machine, which is mainly composed of a yarn clamping disk (11), a yarn guide hole (3), a fixed magnet (1) and a movable magnet (2). Two magnets are used to realize clamping the yarn by an isomerism suction theory. One magnet is a fixed magnet, and the other magnet is a movable magnet. A thread is connected between the movable magnet and a yarn guiding rod. When the yarn guiding rod works, the magnets are pulled apart, and the yarns work normally through a yarn guiding nozzle. When the yarn guiding rod stops working and lifts up, the two magnets attract each other to clamp the yarns to avoid the yarns being blown into a yarn box through an air pipe to be wasted.

Description

Yarn-tensioning device

A kind of annex of textile machine is especially for the tension disk of footwear machine Yarn supply system control yarn.

The yarn of footwear machine Yarn supply system control at present is to utilize the wind in the airduct to control, yarn and thread head when adopting the interior wind inspiration of airduct to quit work in the yarn-guide mouth, and press this one thread with the line ball rod, and five lever jacks of every group of Yarn supply system make yarn be slatterned by wind inspiration yarn box by airduct not in same plane.German patent DE 8332146 knitting machine yarn feeding devices are Tension Control when yarn is current when reeling by the pneumatic coiling of yarn or alternate manner, the DE3301450 knitting machine automatically actively yarn feeding device be that winding angle by the yarn wheel can change the stress that adapts in desired speed and the yarn automatically.Above-mentioned patent is equipped with and adopts tension disk to control the yarn of Yarn supply system.

The purpose of this utility model is to provide the tension disk of a kind of magnet principle that there is a natural attraction between the sexes control yarn, so that idle yarn is clamped, not by in the wind inspiration yarn box, cut the waste, economize in raw materials, reduce process loss, the utility model mainly is made up of clamp dish, fixed magnet, movable magnet, magnet cover, thread guide eyelet.

The utility model is to utilize two blocks of magnet there is a natural attraction between the sexes to come clamp, one is fixed magnet, one is movable magnet, and be connected between movable magnet and the lever jack with single line, when working, lever jack draws back magnet, yarn is by the yarn-guide mouth operate as normal, when lever jack quits work when lifting, two blocks of magnet is inhaled mutually and is clamped yarn and avoid yarn to be slatterned by wind inspiration yarn box by airduct, the lever jack of working on each Yarn supply system when starting working drops to the operating position by original horizontal level, the movable magnet that is connected the other end is just drawn back in backguy on the lever jack, yarn is fed in knitting needle by yarn-guide mouth by the thread guide eyelet in the middle of two blocks of magnet, when quitting work, lever jack gets back to horizontal level by original operating position, movable magnet just is drawn onto on the fixed magnet, and clamp yarn, yarn can not be slatterned in the wind inspiration yarn box in the airduct.

The utility model is to realize like this.Make (11) among the clamp dish figure, go up 60～70 millimeters of the length of sides with 1～2 millimeter copper coin or aluminium sheet, wide 60～70 millimeters, 50 millimeters of the following length of sides, following two ends are 11 millimeters on two fixed angles one side of tension disk fixedly, 16 millimeters on one side, high 8 millimeters, long 10 millimeters of fixed angles waist.140 °～145 ° of angles between stationary plane and the clamp dish, 16 millimeters of the distances of base to two a following waist, two following waists are grown 16 millimeters, 15～20 millimeters of the distances of top to two a last waist, go up long 20～30 millimeters of waist for two, on the clamp dish, get out in 4 guide hole patterns (3), the magnet fixing hole of 4 band screw threads, in 4 backguy hole patterns (5), among the magnet cover figure (4), on the clamp dish, make the fixing hole of each magnet cover and grow 3～4 millimeters, wide 0.5 millimeter, magnet cover is fixed on the clamp dish, get out again in the fixed screw hole pattern (8), 6 millimeters of diameters, 15～18 millimeters of each guide distance between borehole, 6 millimeters of diameters, 32～36 millimeters of the distances in a backguy hole, base to four, backguy hole, both sides is to 7～9 millimeters of two waist intersection points distances, 4 magnet fixing holes are to 6 millimeters of thread guide eyelet distances, 2 millimeters of bore dias, fixed screw holes to bottom margin from 8 millimeters, arrive opposite side distance from 11 millimeters, each thread guide eyelet is by two magnet clamps, among high 5～7 millimeters figure of the length and width of fixed magnet and movable magnet (1), (2), the ditch that two 1 millimeters deep are arranged on the movable magnet, so that clamp movable magnet with magnetic catch, two blocks of magnet space out 3～6 millimeters during lever jack work, fixed magnet fixes the screw hole that the band screw thread of 2 millimeters of diameters is arranged in the middle of (9) frame bottom among the figure with the magnet fixed mount, be connected with backguy one end on the nose of movable magnet folder (10), the other end is connected on the nose of the band circular hole that welds on the lever jack, such nose of all burn-oning on each lever jack, the position is on the vertical point in backguy hole, the distance that movable magnet and fixed magnet drew back when the length of backguy was worked with lever jack is advisable for 3～6 millimeters, the magnet cover of movable magnet outside is made up of four equal areas, the length of each face and wide all be 7～9 millimeters, the backguy hole (7) that the connection movable magnet of 1～1.5 millimeter of individual diameter is arranged on the magnet cover, magnet cover is manufactured with 0.5 millimeter copper or aluminium flake, magnet cover is fixed on the clamp dish, 4～5 millimeters of distances between magnet cover and fixed magnet, the technical problem that must be noted that during installation is the hosiery machine socks waist of casting off, lever jack quits work when lifting in the Yarn supply system of hosiery machine both sides, must set up half at first peg on the cylinder that lifts of this lever jack of control, pacify whole peg for second backward, this piece when on hosiery machine program cylinder control Yarn supply system lever jack being lifted is robbed next piece that tooth rolls the iron back and is rolled iron and move on to this piece and roll on the very tight position, flatly rolls iron and moves on to the back.

Figure (1) is tension disk most preferred embodiment figure, wherein (1) is fixed magnet, and (2) are movable magnets, and (3) are thread guide eyelets, (4) be magnet cover, (5) be plastics mouth on backguy hole and the backguy hole, (6) are backguys, and (7) are the backguy holes on the magnet cover, (8) be fixed screw holes, (9) be the fixed mount of fixed magnet, (10) are the movable magnet folders, and (11) are the clamp dishes.

The utility model has the advantage of to utilize two blocks of magnet there is a natural attraction between the sexes when coming thread-guide stud not work yarn can not be slatterned in the wind inspiration yarn box in the airduct, economize in raw materials, reduce process loss.

Advantage: show according to test data, original 2～4 liang of silk threads of process loss in every machine eight hours, set up tension disk after, can only loss 2～4 money silk threads in every machine eight hours, tension disk is installed after, every machine can reduce process loss about 80%.

Most preferred embodiment: manufacture tension disk with copper, the clamp dish is made of 1.5 millimeters copper coin and is grown up 70 millimeters, wide 70 millimeters, 50 millimeters of bottom side lengths, four thread guide eyelets and four backguy bore dias are 4 millimeters on the clamp dish, the center of circle with thread guide eyelet on thread guide eyelet is the center of circle, making radius is 2.5 millimeters, be 1 millimeter circular groove deeply, tumbling in the plastics mouth on the thread guide eyelet He on the backguy hole respectively, under the plastics mouth on the thread guide eyelet in circular groove, and and the clamp dish in same plane, movable magnet and fixed magnet are all made the high 6 millimeters square of length and width, each face of magnet cover is made 9 millimeters of length and width, is fixed on the center with 5 millimeters of fixed magnet spacings.
