Abstract

The utility model provides a synchronous presser feet for an industrial clothing vehicle, which overcomes the defects that cloth in the upper layer and the lower layer is easy to crinkle due to the fact that the cloth is out-of-sync when the existing presser feet for the clothing vehicle carts goods. The utility model has the technical key points that a cloth-feed gear is arranged in a presser-foot-head slot on the rear side of the presser feet, and the tooth pitch of the gear is coincident with that of a feed dog; the tops of the right presser foot and the left presser foot are respectively provided with a spring, which enables the left presser foot and the right presser foot to be automatically regulated up and down. The utility model has the advantages that the presser feet can be regulated in double directions, and the cloth in the upper layer and the lower layer is synchronous, which smoothes circuitry and improves the quality of the ready-made clothes when carting the goods.

Description

Synchronous mode industry sewing machine presser feet

Affiliated technical field

The utility model relates to a kind of sewing machine, especially industrial sewing machine presser feet.

Background technology

Existing sewing machine is when making ready-made clothes, the feed dog work feed of pressured underfooting cloth lower floor, the cloth upper strata then by and presser feet between friction walking, there is the inconsistent and wrinkling problem of the cloth levels speed of travel easily, usually smooth for dress material is made, in the process of making, must stay layer cloth or remove to lead cloth from the presser feet back, thereby it be irregular stitch often to occur with pulling with hand, the phenomenon of wire jumper or broken needle influences the quality of whole ready-made clothes.

The utility model content

For overcoming the existing technical deficiency of sewing machine presser feet work feed, the purpose of this utility model provides a kind of synchronous mode sewing machine presser feet that can make levels cloth walking unanimity.

Realize that the measure that the utility model purpose is adopted is: by a pair of left and right sides presser feet with have in the sewing machine presser feet that the presser feet head of inverted concave groove constitutes, assembling one work feed gear in the presser feet head groove of presser feet bottom rear, the tooth pitch size of this work feed gear and the feed dog under the degree of depth and the presser feet coincide; One hole of caving in is arranged respectively at presser feet top, the left and right sides, and the spring of packing in the hole is assemblied in two presser feets in the inverted concave groove of presser feet head more simultaneously, and the spring at presser feet top is tight against the groove top.

After adopting above measure, the advantage that the utlity model has is, during the sewing machine operation, when feed dog rises promptly and identical automatically synchronously cloth being hauled of work feed gear seen off, guarantees that the cloth levels is synchronous, makes circuit smooth straight.And left and right sides presser feet can automatic up-down adjustment.

Description of drawings

With reference to the accompanying drawings the utility model is implemented to be described further below:

Fig. 1 is the utility model perspective view.

Fig. 2 is single presser feet stereogram of the utility model.

Among the figure: 1, presser feet head, 2, presser feet, 3, the work feed gear, 4, spring, 5, spring eye.

The specific embodiment

As shown in Figure 1, the sewing machine presser feet is made up of presser feet head 1 and a pair of left and right sides presser feet 2, presser feet 2 is assemblied in the inverted concave groove of presser feet head 1, one spring eye that caves in 5 is arranged respectively at two presser feets, 2 tops, as shown in Figure 2, spring 4 is packed in the spring eye 5, and presser feet 2 is contained in presser feet head 1 groove inner spring 4 and is tight against the groove top, sewing machine when operation, the automatic up-down adjustment of needs when left and right sides presser feet 2 can be according to the car deliver goods.Assembling work feed gear 3 in presser feet head 1 groove of presser feet 2 bottom rear, as shown in Figure 1, the tooth pitch size of this work feed gear 3 and the feed dog under the degree of depth and the presser feet coincide, when feed dog rises, feed dog and work feed gear 3 coincide synchronously cloth to be hauled automatically and see off, work feed gear 3 can be made with steel or colloidal materials according to actual needs, can add cover at the bottom of the gummy bottoms at the bottom of the presser feet.

Claims

1, a kind of synchronous mode industry sewing machine presser feet, by a pair of left and right sides presser feet and have the presser feet head of inverted concave groove to constitute, it is characterized in that: assembling one work feed gear in the presser feet head groove of presser feet bottom rear, the tooth pitch size of this work feed gear and the feed dog under the degree of depth and the presser feet coincide, one hole of caving in is arranged respectively at presser feet top, the left and right sides, the spring of packing in the hole is assemblied in two presser feets in the inverted concave groove of presser feet head more simultaneously, and the spring at presser feet top is tight against the groove top.
