Abstract

A double-edge folder belongs to the technical field of braided fabric sewing, and includes an outer winding drum and an inner winding drum, wherein the outer winding drum is mounted on the outer side of the inner winding drum in a sleeving manner; a horizontal outer side base plate serves as the bottom of the outer winding drum; a horizontal inner side base plate serves as the bottom of the inner winding drum; the outer side base plate and the inner side base plate are parallel to each other; an outer side winding guide plate in smooth transition from 90 degrees to 360 degrees is arranged on one side of the outer side base plate; and an inner side winding guide plate in smooth transition from 90 degrees to 180 degrees is arranged on the same side of the inner side base plate; the edge of the outer side winding guide plate is welded and fixed on the inner side base plate; and a fixed fork plate is welded on the outer wall of the outer winding drum. The double-edge folder has a simple structure, is low in machining cost and improves the production efficiency.

Description

Bilateral hemmer

Technical field

The utility model relates to braided fabric sewing field, specifically a kind of bilateral hemmer.

Background technology

Woven bag is widely used as a kind of packing material, and its main production is to utilize plastic raw materials to be stretched as flat filament through extrusion film, cutting, individual event, is woven into tubular through longitude and latitude, and the joining edge to end mouth carries out flanging at last, forms the woven bag finished product.Before the joining edge of mouth is made at the bottom of using Sewing machines to woven bag, need in advance just can to make this section behind one section flanging of mouth joining edge at the bottom of to woven bag with hand, after shutting down to making again behind next section flanging.Not only the amount of labour is big for this manual mode, inefficiency, and to the difficult quality guarantee of woven bag finished product.In addition, for big part cloth material products such as sheet, curtain, for preventing that the edge off-line from also needing to sew up behind the flanging, manual flanging has above-mentioned shortcoming equally.

The utility model content

The purpose of the utility model is to provide a kind of bilateral hemmer, and this hemmer can improve the fashionable operating efficiency of double-deck hem seam greatly.

The technical scheme that its technical problem of the utility model solution is taked is: bilateral hemmer, comprise outer reel and inner drum, and said outer reel is sleeved on the outside of said inner drum; The bottom of said outer reel is the outside base plate of level, and the bottom of inner drum is the inboard base plate of level, and outside base plate and inboard base plate are parallel to each other; One side of outside base plate is provided with 90 ° of curling guide plates in the outsides to 360 ° of smooth-going transition, and the same side of inboard base plate is provided with 90 ° of curling guide plates in the inboards to 180 ° of smooth-going transition; The edge of the curling guide plate in the outside is weldingly fixed on the inboard base plate, and the outer wall of outer reel is welded with the fixation fork plate.

Described outer reel is a pyramidal structure.

Said inboard base plate is exposed at the outside end of said outer reel and is upturned.

The beneficial effect of the utility model is:

1, simple in structure, be prone to processing and manufacturing, with low cost.

2, replace manual mode of operation, reduce labour intensity, enhance productivity.

Description of drawings

Fig. 1 is the plan structure sketch map of the utility model;

Fig. 2 is the section enlarged diagram of Figure 1A-A direction.

Among the figure: 1 outer reel, 11 outside base plates, 12 outsides guide plate that curls, 2 inner drums, 21 inboard base plates, the 22 inboard guide plates that curl, 3 fixation fork plates.

The specific embodiment

Like Fig. 1, shown in Figure 2.Bilateral hemmer comprises outer reel 1 and inner drum 2, and said outer reel 1 is sleeved on the outside of said inner drum 2; The bottom of said outer reel 1 is the outside base plate 11 of level, and the bottom of inner drum 2 is the inboard base plate 21 of level, and outside base plate 11 is parallel to each other with inboard base plate 21; One side of outside base plate 11 is provided with 90 ° of curling guide plates 12 in the outsides to 360 ° of smooth-going transition, and the same side of inboard base plate 21 is provided with 90 ° of curling guide plates 22 in the inboards to 180 ° of smooth-going transition; The edge of the curling guide plate 12 in the outside is weldingly fixed on the inboard base plate 21, and the outer wall of outer reel 1 is welded with fixation fork plate 3.

Described outer reel 1 is a pyramidal structure, and outer reel 1 front opening area is greater than the aperture area of end.

Said inboard base plate 21 is exposed at said outer reel 1 an outside end and is upturned.Inboard base plate 21 be upturned make when material is put between inboard base plate 21 and the outside base plate 11 convenient.

During work; Through fixation fork plate 3 bilateral hemmer is installed on the sewing device, the edge of woven bag or cloth is reserved the surplus that needs flanging after, put between outside base plate 11 and the inboard base plate 21 from the front end of outer reel 1; When the edge of woven bag or cloth curls guide plate 12 through the outside; Curling guide plate 12 bendings bend to after 180 ° along the outside, and the outer flanging of double-deck flanging forms and supported by the curling guide plate 22 in inboard.Curling guide plate 12 is bent to 360 ° to the remaining folding allowance continuation in woven bag or cloth edge along the outside, forms the internal layer flanging, gets into the sewing operation then.

The above; Some principles of the utility model just explain through diagrams; This specification be not be to the utility model be confined to shown in described concrete structure and the scope of application; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.

Except that the said technical characterictic of specification, all the other technical characterictics all belong to those skilled in the art's known technology.
