Description

Hemming sewing guide tool

Technical Field

The utility model relates to a dust bag production and processing field, in particular to sewing guide frock of borduring.

Background

In the manufacturing process of sewing the dust-removing filter bag, in order to increase the attractiveness of the edge of the filter bag and the firmness of the edge structure, a plurality of filter material cutting pieces need to be folded and then stacked for sewing.

The operator usually folds the edge by a bare-handed mode, and then stitches the folded edge by a sewing machine, and the edge wrapping mode has the disadvantages of large workload and low working efficiency. Although the clothing industry has a special edge binding device, the edge binding device is not suitable for industrial sewing. The glass fiber filter cloth paste P84 surface layer spunlace felt, the PTFE filter material, the woven fabric, the felt and other materials used for manufacturing the filter bag are relatively thick, the edges of the non-woven filter material are folded and sewn by hands, the conditions of deformation, channel falling and the like can be easily caused, the deformed and channel falling materials cannot be used continuously and can only be scrapped.

SUMMERY OF THE UTILITY MODEL

In order to realize the purpose, the utility model discloses the technical scheme who adopts is:

the utility model provides a sewing guide frock of borduring which characterized in that includes:

a first guide chamber and a second guide chamber spirally wound on the fixing portion;

the first guide cavity guides the first sewing cut piece to be folded;

the second guide cavity guides a second sewing cut piece to be turned over, and the second sewing cut piece is overlapped on the first sewing cut piece after being turned over and forms a four-layer overlapping structure;

the fixing part is fixed on the sewing table through a fastener.

In a preferred embodiment of the present invention, the first guide chamber is formed by a first guide outer guide surface and a first guide inner guide surface, which extend, bend and finally converge from a side direction;

the second guide cavity is formed by extending and bending a second guide part outer guide surface from the other side direction and matching with the outer periphery of the first guide part inner guide surface;

first guide chamber with the second guide chamber is respectively from the not equidirectional guide in both sides first sewing cut-parts with the second sewing cut-parts gets into in the frock.

In a preferred embodiment of the present invention, the bending curvatures of the first guide portion outer guide surface and the first guide portion inner guide surface become gradually smaller as they converge and meet.

In a preferred embodiment of the present invention, the widest dimension of the first guide cavity and the second guide cavity is 10mm, and the narrowest dimension is 5mm.

In a preferred embodiment of the present invention, a guiding boss is further disposed in the second guiding cavity, and the guiding boss assists the second sewing panel to turn over.

In a preferred embodiment of the present invention, the outer end of the first guide outer guide surface is connected to a first guide base surface, and the first guide base surface is welded to the fixing portion, thereby fixing the first guide chamber and the second guide chamber.

The beneficial effects of the utility model reside in that:

the utility model provides a sewing guide frock of borduring turns over and fold the back through two cut-parts of frock guide and directly send into sewing machine at rear and sew up, has removed the process that original manual work turned over and has turned over from, reduces the production disability rate.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below.

Fig. 1 is a schematic diagram of the present invention.

Detailed Description

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, a hemming sewing guide tool includes: a first guide chamber 10, a second guide chamber 20, and a fixing portion 30.

The first guide chamber 10 and the second guide chamber 20 are disposed on the fixing portion 30 and spirally wound around each other. The fixing portion 30 is fixed to the sewing table 40 by a fastening member.

The first guide chamber 10 is constituted by a first guide portion outer guide surface 12 and a first guide portion inner guide surface 13 together, the first guide portion outer guide surface 12 and the first guide portion inner guide surface 13 extending from one side direction and gradually closing up. The second guide chamber 20 is constituted by the second guide portion outer guide surface 21 extending from the other side direction and gradually converging with the first guide portion inner guide surface 13. Thereby, the first guide chamber 10 and the second guide chamber 20 respectively guide the first sewing panel (not shown) and the second sewing panel (not shown) from both sides (arrow direction in the figure) into the tool to complete the folding and overlapping steps, and finally, the first sewing panel and the second sewing panel are passed out from the rear end of the tool and sewn vertically downward along the sewing line 50 by the sewing equipment. The outer end of the first guide outer guide surface 12 is connected to a first guide base surface 11, and the first guide base surface 11 is welded to the fixing portion 30, thereby fixing the first guide chamber 10 and the second guide chamber 20.

Simultaneously, in order to reach first guide chamber 10 and guide first sewing cut-parts and turn over, second guide chamber 20 guides second sewing cut-parts and turns over and overlap and form four layers of overlapping structure on first sewing cut-parts after making second sewing cut-parts turn over, and the first guide portion outer guide face 12 and the first guide portion inner guide face 13 the camber of buckling gradually diminishes along with the convergence of the two. The widest dimension of the first guide cavity 10 and the second guide cavity 20 is 10mm, and the narrowest dimension thereof is 5mm. Because the second guide cavity 20 is formed by the second guide part outer guide surface 21 matching with the first guide part inner guide surface 13, in order to prevent the second sewing panel from being turned over and folded unsmoothly after entering the second guide cavity 20, a guide boss 22 is further arranged in the second guide cavity 20 to assist the second sewing panel to be turned over.
