Abstract

The utility model relates to a check-weaving length-setting controller for towel looms, which is composed of a pedal disk shaft 1, a cam 2, a crank rod 3, a connecting rod 4, a swinging rod 5, a support head 6, a pull hook 7, a main serrated wheel 8, chains 9, 13, a small control lever 11, an auxiliary serrated wheel 12, chains 10, 14, a big control lever 15, a swinging arm 16, a positioning disk 17 and a positioning reed 18. The pause time that an impact mouth impacts against an upper and a lower impact blocks is cancelled (namely, the calico knitting movement time of the first section of an original mechanism is cancelled) by changing the structure, and the type with a section of raising the fuzz and a section of knitting the calico (namely, the fuzz raising sections and the calico knitting sections are alternately arranged) is formed, and the fuzz raising width and the calico knitting width can be controlled accurately. The utility model has the advantages of simple structure, convenient operation and low cost.

Description

Check-weaving length-setting controller for towel loom

The utility model relates to a kind of lattice fixed length subsidiary body of knitting, and especially a kind of towel is knitted lattice Length Control mechanism.

Existing terry cloth loom is to make at the technological requirement of conventional towel, can only knit conventional towel, promptly is about in 80 centimeters, and two ends are the plain cloth line, the towel of middle terry.Though this terry cloth loom also has Length Control mechanism, complex structure often is out of order, result of use is poor, it is offscale only to control the towel end, the towel of band lattice in the middle of can not producing (optional position, lattice are wide arbitrarily).Domestic at present if be with the towel of lattice and conversion decorative pattern in the middle of on terry cloth loom, weaving, dobby or full-jacquard mechanism need be attached on the terry cloth loom and can realize, and these two kinds of mechanisms are supporting for weaving intricate detail, weave not too economy of simple check on the terry cloth loom if use.

The purpose of this utility model is in order to provide a kind of simple in structure, easy to operate towel to knit lattice Length Control machine, and the terry cloth loom that this controller is housed can be weaved out the towel of two ends or centre position band lattice.

The utility model is by lower-shaft 1, cam 2, turns bar 3, connecting rod 4, fork 5, strut 6, drag hook 7, positive serrated wheel 8, sprocket wheel 9,13, little control lever 11, pair serrated wheel 12, chain 10,14, big control lever 15, swing arm 16, fixed length dish 17, positioning reed 18 are formed.Its architectural feature is just to pay two serrated wheels in the fixed installation of the centre position of fixed axis A, fixedly mounts sprocket wheel 9 and sprocket wheel 13 respectively in the two serrated wheels outside.Be slidingly installed respectively in the two sprocket wheels outsides positioning disk 17 and positioning disk 17a, chain 14 and 10 are housed on sprocket wheel 9 and 13, the two ends of fixed axis A are contained in respectively among the axis hole A of machine frame at two sides.The front end of fastener 6 and drag hook 7 contacts with just paying serrated wheel respectively, and the rear end of fastener 6 and drag hook 7 flexibly connects by the upper end of connecting axle J and fork 5.One end of the lower end of fork 5 and connecting rod 4 flexibly connects, and the other end of connecting rod 4 is by bearing pin K and turn bar 3 flexible connections.Turn bar 3 and flexibly connect, play lattice swing arm 16 and be movably arranged on the fluffing axle E, on fluffing axle E, mouth hit 23 is housed also simultaneously by lower-shaft 1 and cam 2.One end of fluffing swing arm 16 utilizes the pulling force of spring 24 to contact with cam 2, and the other end that plays the lattice swing arm is controlled by the following hook of big control lever 15.Big control lever 15 is installed on the frame by axle B.The end of big control lever 15 contacts with the front of paying chain 14 by the relay of spring 25.Little control lever 11 is movably connected on the frame by axle D, and an end of little control lever 11 contacts with drag hook 7, and the other end contacts with positive the top of chain 10 by the pulling force of spring 26.Positioning reed 18 is fixedly mounted on the frame, and the upper end of positioning reed 18 contacts with positioning disk 17a.

Below in conjunction with accompanying drawing architectural feature of the present utility model is further specified:

Accompanying drawing 1 structural representation of the present utility model.

Accompanying drawing 2 rack construction schematic diagrames.

Wherein: 1 lower-shaft, 2 cams, 3 turn that bar, 4 connecting rods, 5 forks, 6 fasteners, 7 drag hooks, 8 positive serrated wheels, 9 sprocket wheels, 10 chains, 11 little control levers, 12 pairs of serrated wheels, 13 sprocket wheels, 14 chains, 15 big control levers, 16 swing arms, 17 positioning disks, 18 retainer spring sheets, 19 fluffing arms, 20 fluffing bars, 21 steel are buckled, 22 rocker Button Blocks, 23 mouth hits, 24,25,26 spring first frames, second frame.

Above-mentioned each part is metal material and makes, and is wherein just paying serrated wheel 18,12, chain 10,14, and spring 24,25,26 is the ready-made part of purchasing, and on chain 10,14 triangular key is set.One minor axis C is arranged on the top of fork 5.Fluffing arm 19, fluffing bar 20, steel button 21, rocker Button Block 22, mouth hit 23 and frame first, second are the parts of former towel loom.Other each parts promptly can be made into shown in said structure feature and accompanying drawing 2.When mounted will be with axle A, B, C, E, F, G, H, I, D is corresponding respectively to be installed among hole A ', B ', C ', D ', E ', F ', G ', H ', the I ' of frame first, second.

The utility model is installed on the terry cloth loom just can knits the lattice Length Control.Its transmission operation principle is as shown in Figure 1: lower-shaft 1 rotating cam 2, swing arm 16 is swung up and down, drive simultaneously and turn bar 3 kinematic links 4, make the swing of swing arm 5 fore-and-aft directions, fastener 6, drag hook 7 is swung simultaneously, with positive 8 support past of serrated wheel tooth, sprocket wheel 9 changes a tooth simultaneously, and driving chain 10 commentaries on classics shot of a cable, the triangular key on the chain 10 makes little control lever 11 actions, makes drag hook 7 decline pulling pair sprocket wheels 13 change a tooth after little control lever 11 actions, pay chain 14 and change shot of a cable, the triangular key of paying on the chain 14 makes big control lever 15 actions, hooks or decontroled lattice swing arm 16, and swing arm 16 made the motion of the mouth hit 23 on the former towel loom.

The control fixed length mechanism of former towel loom is that two collision blocks up and down by mouth hit 23 bump fluffing arms 19 ends play the fixed length effect, its motion mode fluffs when being the bump collision block, intermittent time is knitted first section plain cloth (playing lattice), when descending collision block, knits bump second section plain cloth (playing lattice), and then bump is gone up the collision block fluffing, so return reciprocating cutter, can only weave the conventional towel style of two sections plain cloths of one section hair (i.e. one mao of two lattice), and form the width that accurately to control fluffing and plain cloth because its former control length is a cover train.New-type motion of mechanism describes in detail.When mouth hit 23 is passed in motion, make mouth hit cancel the intermittent time of collision block about the bump (being about to first section run duration cancellation of knitting plain cloth of former mechanism), form one section fluffing and knitted flat fabric (i.e. one mao of one a lattice) style for, and can control the width of a fluffing and a lattice exactly.

The utility model is the auxiliary device of terry cloth loom, is used in combination with terry cloth loom.It is simple in structure, easy to operate, and parts are durable, changes flexibly.
