Abstract

The utility model is a completely automatic double blowing lap sewing guiding device, which has two blowing air parcels and a photoelectric induction switch. When finding cloth is placed in, the utility model controls the air pressure cylinder to pull back, driving the left blowing air parcel to move towards right, guiding the desiring sewing to become right convexity flute shape, and blows air from the left and the right simultaneously, the function of the right blowing air parcel is to guide cloth to localization board, fixing the lap width of sewing, but the goal of the left blowing air parcel is to make cloth truly smooth and extended, avoiding producing corrugation; When sewing is at a cloth joint, because the joint is two pieces of cloth overlapped, the relative thickness increases, digs hollow underneath the working platform bearing cloth, places a cushion module absorbing the cloth increasing thickness, after passing through the joint, the cushion module and the working platform are at the same plane again; when the photoelectric induction switch detects the end of the sewing, pulls out the air pressure cylinder, driving the left blowing air parcel to move towards left, and stopping blowing simultaneously, continues sewing to the end.

Description

Full-automatic two formula bottom sewing guiding device that blows

Technical field

The utility model relates to a kind of guiding device, particularly be that a kind of stream condition that utilizes blows guiding with sewing cloth, form the bottom sewing guiding device of the bending of a bottom automatically.

Background technology

See also Figure 10, described figure is a clothing sewing schematic diagram, and general clothing is that two clothes in front and back 9 engage, and two cloth 9 overlapping seam crossings are selvedge seam sideline 90, all can the inside sewing of reflexed at cloth 9 lower edges, and the bottom 91 of meaning.

Use in sewing machine in the past is when the sewing bottom 91, must be with the back sewing that manually the selvedge bending is shaped, way in the past is by with artificial bending, so the efficient of work depends on the degree of haveing the knack of to described skill the sewer, and not familiar new hand often operating efficiency is low, and usually cause suture to distort, so need improvement badly.

Other has the creation of using for many years to set up the bending mechanism of convenient bending on board, see also Fig. 1, existing sewing machine 1 is installed existing bending member 12 and existing profiled member 11 on existing board 10, by manpower cloth bending is imported in existing bending member 12 and the existing profiled member 11, make cloth along existing bending member 12 with existing profiled member 11 moulding and sewing is the bottom; And cloth easily produces fold in existing bending member 12 and existing profiled member 11, make the bottom distorted deformation of sewing, and width is difficult to control homogeneous; The crack is to separate adjustment between between existing again bending member 12 and the existing profiled member 11, when adjusting the sewing skirt width, desire needs tool using, and adjust and be difficult for, and also non-cushioned space, existing board 10 belows, so the difficulty in the use is caused in crack between the sewing cloth joint can be stuck in and fix between existing bending member 12 and the existing profiled member 11.

Though there is other creation to increase by a compressible sheet metal as buffering, but described sheet metal is single-point support one to be stressed is that full wafer moves down, and described sheet metal because of fulcrum partially in a side, single load bearing is being that sheet metal is during to lower compression, one side compression stroke deficiency near fulcrum, can't guarantee seam crossing is passed through smoothly, idol has cloth to block situation, poor effect.

Because of existing bottom sewing guiding device still has many improved spaces of demanding urgently, the creator of this case is engaged in the manufacturing and the creative experience of described industry for many years by it, and hammer away improves the disappearance of various existing products, created full-automatic two formula bottom sewing guiding devices that blow of this case.

Summary of the invention

The purpose of this utility model is, a kind of full-automatic two formula bottom sewing guiding devices that blow are provided, reach to make and desire sewing bottom cloth automatic forming, have Buffer Unit again and can absorb the thickness of sewing joint, make sewing bottom process fast smooth-going and make the width homogeneous of the bottom, and adjust the sewing skirt width and operate easy purpose.

For achieving the above object, the technical solution adopted in the utility model is, a kind of full-automatic two formula bottom sewing guiding devices that blow are provided, be that two air blowing pieces make the guiding device of the automatic smooth-going moulding of cloth cover of desiring the sewing bottom about having, it is characterized in that, it comprises left air blowing piece, right air blowing piece, rotate skirt width adjusts button, Buffer Unit and cover plate, wherein

Described left air blowing piece is a tabular block, have several pores that inner air pipeline and set screw are sealed, described left air blowing piece below makes the connecting line compressed-air blows by a right angle snap joint, and below block, be provided with inflatable mouth, described inflatable mouth is outward one to have the groove of circular arc outer rim

Described right air blowing piece be a below be provided with that cylinder supports than the chunk body, described external appearance characteristic than the chunk body is that a side is right convex groove, and described right air blowing piece also is provided with several pores that inner air pipeline and set screw are sealed, and in right convex groove, be provided with inflatable mouth, right air blowing piece side is installed a pipe joint to insert compressed air, and the columnar stays piece of right air blowing piece below is provided with a circular hole and passes for a rotating shaft;

Described rotation skirt width is adjusted when button makes the rotating shaft rotation drive the feed shaft displacement can make the displacement of right air blowing piece simultaneously, and make left air blowing piece displacement location, by a left side, moving and the width of the adjustment bottom of right side air blowing piece, the position of board carrying cloth hollows out the Buffer Unit that the sewing joint of establishing a cloth when making sewing can pass through smoothly again, described Buffer Unit is one to be repeatedly " S " shape folding and the flexible sheet metal of tool, dull and stereotyped both sides, described Buffer Unit top become the wing reflexed and extend two flanks to be used in the below of replacing cover plate, and described being " S " the sheet metal end of shape bending respectively has fixing hole locking at cover plate to both sides.

Advantage of the present utility model is listed below:

1. Buffer Unit can allow the sewing joint of thicker cloth pass through smoothly;

2. twoly about having blow the formula design, the guiding cloth is located really, guarantee the skirt width homogeneous of sewing, and the crease place does not produce fold;

3. the cloth at all thickness is fitted in crack between between left air blowing piece of simple and easy adjustment and the right air blowing piece;

4. skirt width adjustment mode is simple, need not use any instrument;

5. easy and simple to handle and automation, left-hand seat very easily, and increase work efficiency;

6. have an industrial circle practical value.
