Abstract
The invention discloses a yarn clamping device for circular machine high-elasticity yarns. The yarn clamping device comprises an exhaust opening, a yarn clamping mechanism and a control mechanism. The yarn clamping mechanism and the control mechanism are both arranged on the exhaust opening. The control mechanism controls the yarn clamping mechanism to finish yarn clamping. The yarn clamping mechanism comprises a first yarn clamping piece and a second yarn clamping piece. A yarn hooking piece is arranged between the two yarn clamping pieces, and can rotate between the first yarn clamping piece and the second yarn clamping piece and around a shoulder screw. The control mechanism comprises a fixed seat and cylinders. In work, air enters the cylinders to drive the yarn hooking piece to rotate, the cylinders swing in a cooperated mode at the same time, and through the cooperated swinging, piston rods are prevented from stiffly driving the yarn hooking piece to move. By means of the yarn clamping device, the high-elasticity yarns at the exhaust opening can be effectively clamped, and the problem of difficult yarn clamping of the second path and the fourth path of a four-path hosiery circular knitting machine is solved.

Summary of the invention
In order to solve the problem, the invention provides a kind of wire-clamping device for high-elasticity yarn in circular knitting machine, thus solve the problem of high-elasticity yarn clamp difficulty.
Adopt following technical scheme: a kind of wire-clamping device for high-elasticity yarn in circular knitting machine for this reason, described wire-clamping device comprises inlet scoop, thread clamping mechanism and controlling organization, described thread clamping mechanism and controlling organization are installed on inlet scoop, by controlling organization, thread clamping mechanism is controlled, thus complete clamp; It is characterized in that: described thread clamping mechanism comprises the first thread tension disc and the second thread tension disc that there is between two thread tension discs a hook line sheet; Thread clamping mechanism also comprises an axial screw, first thread tension disc, hook line sheet and the second thread tension disc also has installing hole, described axial screw passes the second thread tension disc successively, hooks the installing hole on line sheet and the first thread tension disc and be movably connected on inlet scoop, by at least one dog screw, the first thread tension disc and the second thread tension disc are fixed on inlet scoop again, described hook line sheet can rotate at the spaced winding axial screw of the first thread tension disc and the second thread tension disc; Described controlling organization comprises holder and cylinder, holder is fixed on inlet scoop, described cylinder is fixedly connected with a clamp, described cylinder is connected with holder by clamp, have piston rod in cylinder, described piston rod one end is positioned at cylinder, and the other end fixes a connecting piece, described brace and hook line sheet top are hinged, and described cylinder drives hook line sheet can rotate around axial screw by brace.
Further, described controlling organization also comprises a rotating screw, and described rotating screw is movably connected between the clamp of cylinder and holder, makes clamp that dynamic air cylinder can be with to swing around holder occurred level by rotating screw.
Further, described thread clamping mechanism also comprises a clamp clip, and described clamp clip has installing hole, is fixed on the outside of the second thread tension disc by described axial screw and dog screw.
Further, described wire-clamping device also comprises the first back-up ring and the second back-up ring, and described first back-up ring and the second back-up ring are fixed on respectively by screw and hook on movement locus that line sheet rotates around axial screw.
During work, cylinder intake drives piston rod movement, brace on piston rod drives hook line sheet to rotate around axial screw, described cylinder can by the rotating screw between clamp and holder, collaborative swing is carried out to the rotation hooking line sheet, can prevent piston rod from driving the motion hooking line sheet too stiff by collaborative swing.After hooking line sheet hook line, then by return hydraulic cylinder, yarn is clipped between the first thread tension disc and the second thread tension disc, when strength is not enough when between two thread tension discs, can be compensated by clamp clip; Described first back-up ring and the second back-up ring can carry out spacing to the position hooking the rotation of line sheet, prevent from hooking when line sheet rotates exceeding normal range (NR).By the present invention, effectively can carry out clamp to the high-elasticity yarn at inlet scoop place, solve the problem of four hosiery circular knitter Zhong Second Roads, road and four road clamp difficulties.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present embodiment.
Detailed description of the invention
See accompanying drawing.The present embodiment comprises inlet scoop 1, thread clamping mechanism and controlling organization, and described thread clamping mechanism and controlling organization are installed on inlet scoop 1, are controlled thread clamping mechanism by controlling organization, thus complete clamp.Described clamp framework comprises between the first thread tension disc 2, second thread tension disc 5 and clamp clip 6, two thread tension disc and has a hook line sheet 4; Thread clamping mechanism also comprises an axial screw 7, clamp clip 6, second thread tension disc 5, hook line sheet 4 and the first thread tension disc 2 also has installing hole, described axial screw 7 passes clamp clip 6, second thread tension disc 5 successively, hooks the installing hole on line sheet 4 and the first thread tension disc 2 and be movably connected on inlet scoop 1, by upper dog screw 132 and lower dog screw 131, clamp clip 6, second thread tension disc 5 and the first thread tension disc 2 are fixed on inlet scoop 1 again, described hook line sheet 4 can rotate at the spaced winding axial screw 7 of the first thread tension disc 2 and the second thread tension disc 5; Described wire-clamping device also comprises the first back-up ring 31 and the second back-up ring 3, described first back-up ring 31 is fixed on by upper dog screw 132 that to hook the movement locus that line sheet 4 rotates around axial screw 7 up, and the second back-up ring 3 is fixed on by lower dog screw 131 that to hook the movement locus that line sheet 4 rotates around axial screw 7 descending.
Described controlling organization comprises holder 11 and cylinder 10, holder 11 is fixed on inlet scoop 1, described cylinder 10 is fixedly connected with a clamp 9, described control device also comprises a rotating screw 12, described rotating screw 12 is movably connected between the clamp 9 of cylinder 10 and holder 11, makes clamp 9 that dynamic air cylinder 10 can be with to swing around holder 11 occurred level by rotating screw 12; There is in cylinder 10 piston rod 101, described piston rod 101 one end is positioned at cylinder 10, the other end is fixed a connecting piece 8, described brace 8 and hook line sheet 4 top are hinged, and described cylinder 10 drives hook line sheet 4 can rotate around axial screw 7 by brace 8.
