Description

Seal dust-removal cloth-bag

Technical field

The utility model relates to dust-removal cloth-bags.

Background technique

Dust-removal cloth-bag is usually to use woven bag made of fibrous braid, since dust-removal cloth-bag is all to have fibrous braid system At generalling use the mode of sewing in fibrous braid junction, there are several point defects in this way: first is that be sewed and connected place there is Pin hole, dust can be run out of from pin hole when the presence of pin hole filters dust settling pocket, affect the effect of filtering；Second is that sewing connects The intensity for meeting place is not high, junk is easy, so that this dust-removal cloth-bag service life being sewed and connected is shorter.

Utility model content

In order to solve the problems, such as background technique, the utility model provides sealing dust-removal cloth-bag, the sealing cloth bag By the way that coating is arranged to sewing junction, so that the dust-removal cloth-bag has good leakproofness, and has filter effect good, make With the service life it is long the advantages that.

In order to achieve the above objectives, the utility model adopts the following technical solution:

Dust-removal cloth-bag, including bag body are sealed, bag body is connected by two sides of monolithic fibre knitting cloth by middle interconnecting piece It is formed after connecing, middle interconnecting piece includes the inner side edge on the inside of bag body, the outer side edges on the outside of bag body, inner side edge and outside While being connected by sewing thread, it is characterised in that: the outer surface of outer side edges position corresponding with sewing thread is coated with adhesive glue, bonding Glue forms coating after blast heater is dry, and coating closes the sewing hole of sewing thread.

The end of inner side edge is provided with the flanging towards outside, and the end of outer side edges is provided with in-flanges inwards, interior Flange is extend into the gap between flanging and inner side edge, and flanging is extend into the gap between in-flanges and outer side edges.

All it is connected by bonding agent between in-flanges and flanging.

Flanging is connected by interior arc side with inner side edge；It is connected between in-flanges and outer side edges by outer arc side.

Sewing thread is three, and three sewing threads are parallel to each other and extend along the length direction of bag body.

The beneficial effects of the utility model are:

By the way that the method that adhesive glue forms coating is arranged at the place of being sewed and connected, so that the pin hole for being sewed and connected place of dust settling pocket It is closed, dust will not escape from pin hole when this spline filter, ensure that filter effect；Glue+sewing thread+flange fixation simultaneously Mode can be used for a long time and not damage so that the junction intensity of dust settling pocket is larger, extend the service life of dust-removal cloth-bag.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawing

Fig. 1 is the overall structure diagram of dust-removal cloth-bag described in the utility model；

Fig. 2 is the middle interconnecting piece structural schematic diagram of dust-removal cloth-bag in Fig. 1.

Specific embodiment

Explanation and specific embodiment are further described the utility model with reference to the accompanying drawing:

Embodiment 1

As shown in Figure 1, dust-removal cloth-bag, including bag body 1, bag body 1 pass through centre by two sides of monolithic fibre knitting cloth It is formed after the connection closing of interconnecting piece 2.

As shown in Fig. 2, middle interconnecting piece 2 includes the inner side edge 10 positioned at 1 inside of bag body, positioned at the outside in 1 outside of bag body Side 20, the end of inner side edge 10 are provided with the flanging 12 towards outside, and flanging 12 is connected by interior arc side 11 with inner side edge 10； The end of outer side edges 20 is provided with in-flanges 22 inwards, is connected between in-flanges 22 and outer side edges 20 by outer arc side 21.

In-flanges 22 is extend into the gap between flanging 12 and inner side edge 10, flanging 12 extend into in-flanges 22 with In gap between outer side edges 20.Adhesive layer 30 is provided between in-flanges 22 and flanging 12.In this way, from the inside to the outside, inside Intermediate overlapping layers is formed between side 10, in-flanges 22, adhesive layer 30, flanging 12 and outer side edges 30.

Three sewing threads 40 are set on intermediate overlapping layers, and three sewing threads 40 are parallel to each other and along the length side of bag body To extension.

Outer application on overlapping layers positioned at bag body has adhesive glue, and viscose glue forms coating 24 after blast heater is dry, applies Layer 24 by sewing thread 40 on the outside of the bag body on sewing hole cover.

The dust-removal cloth-bag is connected by above-mentioned middle interconnecting piece, so that the connection of fibre knitting cloth has securely, coating Use so that bag body keeps preferable leakproofness, so that the filter bag has long service life, the good spy of filter effect Point.

It will be recognized by those skilled in the art, can be to above-mentioned under the premise of without departing from protection scope of the present invention Embodiment is carry out various modifications, changes and is combined, and thinks that this modification, variation and combination are the models in originality thought Within enclosing.
