Abstract

The utility model discloses a sinker control device. The sinker control device comprises a mother board, at least one group of sinker control triangle and a driving mechanism, wherein at least one long slotted hole is arranged on the mother board, and the driving mechanism is penetrated through the long slotted hole of the mother board and is connected with the sinker control triangle, thereby driving the sinker control angle to move left and right; the sinker control device is characterized in that a downward projecting part is arranged in the middle part of the lower edge of the sinker control triangle and is in smooth connection with the other parts of the lower edge of the sinker control triangle; the lower edge of the mother board is provided with an outward raised end; and when the sinker control angle is at an initial position, the raised end of the mother board and the projecting part of the sinker control triangle are at corresponding positions. The working process of the sinker control device is as follows: the driving mechanism drives a guiding block to move left and right in the long slotted hole, i.e. driving a first spring seat and the sinker control triangle to move left and right, and as the sinker control triangle and the guiding block are connected through long holes and dowels, the sinker control triangle also moves up and down relative to the guiding block; when the sinker control triangle moves till the raised end of the mother board corresponds to the projecting part of the sinker control triangle, the raised end lifts the sinker control angle to enable the sinker control angle to quit working and be at a zero position; and the lengthwise movement of the sinker control triangle is influenced by a spring, when the sinker control triangle lengthwise moves, and certain elasticity exists, thereby providing flexible pressing for a sinker.

Description

Device for controlling sinker

Technical field

The utility model belongs to technical field of knitting machinery, especially relates to a kind of device for controlling sinker.

Background technology

Flat machine is in the process of braiding garment piece, and lopping and barring-on are the indispensable braiding requirements of garment piece.Whether the quality of lopping with turn over the stable coil that depends on of pin closely suitable with cooperating of crochet hook, and make coil suitable with cooperating of crochet hook, must could accomplish with the mode of tractive garment piece or the mode of pushing coil.Sinker promptly is the important composition parts of pushing coil, helping lopping, through the control of sinker control triangle device, lets sinker rotate around fulcrum, its pressing position is changed, thereby coil is produced pressure, helps lopping.

The applicant once applied for some patents about device for controlling sinker at this; As 200710068736.2,200910154096.6,201010522488.6 etc.; These sinker controlling organizations generally all comprise the motherboard that has long slot bore; Be located at the positive sinker control triangle of motherboard, be located at the driving mechanism at the motherboard back side, driving mechanism passes long slot bore and drives sinker control triangle.Difference between the different device for controlling sinker is that the movement locus that sinker control triangle is equivalent to motherboard distinguishes to some extent, and the design through the different elasticity parts, makes sinker control triangle produce needed pressing force.

Although multiple technical scheme about device for controlling sinker has been arranged, people still hope constantly it to be made improvement.Up-to-date demand is for the state of not knitting corresponding to sinker, needs the function of sinker being controlled the trigonometric regression zero-bit.

The utility model content

The purpose of the utility model is for the state of not knitting corresponding to sinker, and a kind of device for controlling sinker with the function of making zero is provided.

For this reason; The technical scheme that the utility model adopts is: device for controlling sinker; Comprise motherboard, have at least one long slot bore on the motherboard, and at least one group of sinker control trigonometric sum driving mechanism; The long slot bore that driving mechanism passes motherboard is connected with sinker control triangle, thereby drives sinker control triangle move left and right; It is characterized in that: the lower edge mid portion of said sinker control triangle has a downward protuberance, with other part smooth connections of sinker control triangle lower edge; The motherboard lower edge has an outside protruding end; When sinker control triangle was in initial position, the protuberance of the protruding end of motherboard and sinker control triangle was in correspondence position.

The protruding end of said motherboard is a bearing.

Further, be provided with a bootstrap block in the long slot bore of motherboard, be fixedly connected, fixing simultaneously one first spring base on the bootstrap block with driving mechanism; Have two slotted holes longitudinally on the sinker control triangle, be connected through pin with bootstrap block; The rear side of sinker control triangle is provided with second spring base, is provided with spring between first spring base and second spring base.

The course of work of the utility model is such: driving mechanism drives bootstrap block move left and right in long slot bore; Promptly drive the side-to-side movement of first spring base and sinker control triangle; Because sinker control trigonometric sum bootstrap block links to each other through slotted hole, pin, sinker control triangle also can move up and down with respect to bootstrap block; When the protuberance of the protruding end that moves to motherboard and sinker control triangle at once, this protruding end is controlled triangle with sinker and is lifted, and it is deactivated, and is in zero-bit; The lengthwise movement of sinker control triangle receives the influence of spring, when its lengthwise movement, always has certain elasticity, thereby can flexible pushing be provided to sinker.

The specific embodiment

Shown in accompanying drawing; Device for controlling sinker; Comprise sinker control triangle 1, spring fixed block 2, bootstrap block 3, tooth bar 4, connecting rod 5, sinker motherboard 6, spring 7, pin 8, have at least one long slot bore 61 on the motherboard 6, and at least one group of sinker controlled triangle 1 and driving mechanism; Sinker control triangle 1 comprises trumpet-shaped sinker import (outlet) 11,

guide rail

12 and 13 and press section 14; Driving mechanism comprises tooth bar 4, connecting rod 5, and the long slot bore 61 that driving mechanism passes motherboard 6 is connected with sinker control triangle 1, thereby drives sinker control triangle 1 move left and right; The lower edge mid portion of said sinker control triangle 1 has a downward protuberance 15, with other part smooth connections of sinker control triangle 1 lower edge; Motherboard 6 lower edges have an outside protruding end 62; When sinker control triangle 1 was in initial position, the protruding end 62 of motherboard 6 was in correspondence position with the protuberance 15 of sinker control triangle 1; The protruding end 62 of said motherboard 6 is a bearing; Be provided with a bootstrap block 3 in the long slot bore 61 of motherboard 6, be fixedly connected, fixing simultaneously one first spring base 2 on the bootstrap block 3 with driving mechanism; Have two slotted holes 16 longitudinally on the sinker control triangle 1, be connected through pin 8 with bootstrap block 3; The rear side of sinker control triangle 1 is provided with second spring base, is provided with spring between first spring base and second spring base.
