Description

Automatically the adjusting clothes-stopping structure of sewing machine

The utility model relates to the woolens field of mechanical technique, refers in particular to a kind of clothes-stopping structure of adjusting automatically that can regulate sewing machine retaining garment piece and dials gap, that be used to weave various collar, coat-sleeve etc. automatically.

At present, along with domestic, international exchange of technology, the competition of all trades and professions is growing more intense; Particularly at knitting industry, competition is by for outstanding.Manufacturer is for to be in the invincible position in competition, and just must try every possible means from aspects such as machinery, people, material, methods reduces cost.But just present, be used in the common desk-top sewing machine of knitting industry, its garment piece hangs on the dials, and large needle is to be woven outward by the lining; Therefore, a retaining garment piece is arranged in order to the fixing garment piece of sewing up below acupuncture, this retaining garment piece is fixed, and retaining garment piece and dials gap can't be regulated automatically.Because the thickness of clothing own differs, Bian Zhi the number of plies is also different sometimes, at the braiding garment piece the thin or number of plies more after a little while, the retaining garment piece is bigger with the dials gap, garment piece can about activity cause the instability of stitching mark in acupuncture when weaving like this; Thicker or the number of plies of braiding garment piece more for a long time, garment piece is difficult to again get between retaining garment piece and the dials, resistance is bigger when causing dials to advance.

The purpose of this utility model is to provide a kind of and keeps off garment piece and the dials gap can be regulated automatically, can stably weave the improvement structure of big or small pin of the sewing machine of different-thickness garment piece.

The utility model is achieved by the following technical solution: the retaining garment piece is fixed on the retaining garment piece support, retaining garment piece support can fix along the slide bar that axis slides by its threaded post and slack adjuster, and slack adjuster is connected with hinge with holder by the circular hole hole on its sliding seat projection; The screwed hole that the guide pin bushing of slack adjuster utilizes screw to pass on the sliding seat is fixed in the dowel hole of sliding seat, and guide pin bushing one end is fixed with the bonnet other end and is inserted with slide bar, and the built-in main spring of guide pin bushing, both ends of the spring contact with bonnet and slide bar termination respectively; Little spring one end of slack adjuster is placed on the corresponding with it projection of holder, and the other end is pressed on the table top of sliding seat; The threaded portion of the guide screw of slack adjuster is fixed on the screwed hole of slide bar, and its nut partly is placed in the cannelure of guide pin bushing.

The utility model is because main spring and little spring acting in conjunction make the retaining garment piece be close to acupuncture all the time, and pushes garment piece to dials, do not have the gap between garment piece and the dials, and garment piece can be movable in acupuncture, and the seam mark is highly stable; And garment piece is when thicker, only with the main spring compression, and can not increase the resistance of dials, satisfies the braiding of different garment piece thickness.

Below in conjunction with accompanying drawing the utility model is further specified:

Accompanying drawing 1 is the utility model installation diagram

Accompanying drawing 2 is the utility model exploded view

See accompanying drawing 1,2, the utility model includes retaining garment piece 1, retaining garment piece support 2, slack adjuster 3, holder 4, and holder 4 is fixed on its pedestal; Retaining garment piece 1 is fixed on the retaining garment piece support 2, retaining garment piece support 2 can fix along the slide bar 31 that axis slides by its threaded post 21 and slack adjuster 3, and slack adjuster 3 is connected with hinge by the circular hole 331 on its sliding seat 33 projections and holder 4; The screwed hole 334 that the guide pin bushing 32 of slack adjuster 3 utilizes screw to pass on the sliding seat 33 is fixed in the dowel hole 332 of sliding seat 33, guide pin bushing 32 1 ends are fixed with bonnet 35 other ends and are inserted with slide bar 31, guide pin bushing 32 built-in main springs 34, spring 34 two ends contact with bonnet 35 and slide bar 31 terminations respectively; Little spring 36 1 ends of slack adjuster 3 are placed on the corresponding with it projection 41 of holder 4, and the other end is pressed on the table top 333 of sliding seat 33; The threaded portion of the guide screw 37 of slack adjuster 3 is fixed on the screwed hole 311 of slide bar 31, and its nut partly is placed in the cannelure 321 of guide pin bushing 32.

When using the utility model, retaining garment piece 1 relies on retaining garment piece support 2 to be fixed on the slide bar 31 of slack adjuster 3; Pin on the dials is driven the inserting needle withdraw of the needle, and braided fabric is woven, and by retaining garment piece 1 and dials braided fabric is fixed; 3 pairs of retainings of slack adjuster garment piece 1 is regulated with the dials gap, to satisfy the requirement of the braided fabric that weaves different-thickness, its adjusting is: when the braided fabric thickening, braided fabric is to retaining garment piece 1 effect one power away from dials, and this power passes to slide bar 31 by retaining garment piece support 2, because main spring 34 places in the guide pin bushing 32, one end contacts with end cap 35 on being fixed on guide pin bushing 32, and guide pin bushing 32 is fixed on the sliding seat 33, makes slide bar 31 compress main springs 34, and main spring 34 shrinks; Like this, slide bar 31 is to away from dials direction motion, thereby makes that by means of retaining garment piece support 2 retaining garment pieces 1 can be away from dials, increases the gap of retaining garment piece 1 and dials, satisfies the thickening of braided fabric; In like manner, the braided fabric attenuation, then main spring 34 elongations by compression make the gap smaller of keeping off garment piece 1 and dials, to satisfy the attenuation of braided fabric; Because the threaded portion of guide screw 37 is fixed on the screwed hole 311 of slide bar 31, its nut partly is placed in the cannelure 321 of guide pin bushing 32, when slide bar 31 after moving certain distance on the guide pin bushing 32, the nut of guide screw 37 partly withstands cannelure 321 terminations of guide pin bushing 32, make slide bar 31 no longer mobile, thereby control slide bar 31 drives retaining garment piece 1 and moves in certain scope, gets loose and be not interposing at; Because the screwed hole 334 that guide pin bushing 32 relies on screw to pass on the sliding seat 33 is fixed, can regulate the position of guide pin bushing 32 in the dowel hole 332 of sliding seat 33 by unscrewing and screwing screw, regulate the reference position of slide bar 31, thereby different braiding thickness wider is satisfied in the reference position of auxiliary adjustment retaining garment piece 1; Be connected with hinge in the sliding seat 33 of slack adjuster 3 and holder 4, little spring 36 1 ends are placed on the corresponding with it projection 41 of holder 4, the other end is pressed on the table top 333 of sliding seat 33, in nature, little spring 36 pressurizeds, its power of stretching make sliding seat 33 around its with holder 4 to be connected hinge counterclockwise; Because guide pin bushing 32 is fixed on the sliding seat 33, slide bar 31 inserts in the sleeve of guide pin bushings 32, slide bar 31 is also driven upwards rotate, and upwards the rotating of slide bar 31 will keep off garment piece support 2 and be driven upwards, thus make keep off garment piece 1 with acupuncture near, make the braiding stability-of-path.
