Through changing the pure metal conducting material on the original filter bag into the composite material made of the non-woven fabric, the conductive belt becomes soft and is easy to sew, and the production beat of the sewing process is improved.
Description
Technical Field
The utility model relates to an industrial dust removal filter bag field, in particular to conductive band and high temperature dust removal filter bag convenient to sewing.
Background
The filter bag without the function of conducting electricity is used in the dust collection working condition with large dust concentration and static electricity, dust explosion is easily caused, the filter bag and other dust collector accessories are damaged, and even larger safety accidents are caused.
The Chinese patent No. CN105854442B discloses a method for manufacturing a conductive filter bag. The bag body is sewn with the conductive belt by manufacturing the conductive belt by adopting a bare copper flat wire. Due to the influence of the thickness and the hardness of the conductive belt of the bare copper flat wire, when the conductive belt is sewn with certain high-temperature filter materials (such as a flumeis filter material), the sewing machine pillow is difficult to penetrate through the filter material and the conductive belt simultaneously. In addition, a person specially needs to pull the thicker and harder conductive band in front of the sewing machine to prevent the conductive band from being furled. The problems of unsmooth feeding, frequent needle skipping and the like in sewing are caused, and the production efficiency of a production line is seriously reduced.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is:
a conductive strap for facilitating sewing, comprising:
the middle layer is a mesh belt layer and is used as a base layer for the lapping process of other materials;
a conductive layer disposed over the intermediate layer by a web forming process from conductive fibers;
and the heat-resistant layer is arranged below the middle layer through a net forming process.
In a preferred embodiment of the present invention, the conductive layer and the heat-resistant layer form an interlaced and compact three-dimensional structure after 2 times of the water needling process.
In a preferred embodiment of the present invention, the densities of the conductive layer and the heat-resistant layer are equal.
In a preferred embodiment of the present invention, the conductive fiber is any one of a stainless steel fiber or a carbon fiber.
In a preferred embodiment of the present invention, the heat-resistant fabric is woven by using heat-resistant fibers, and the heat-resistant fibers are any one of PPS fibers, baodelon, polyimide, or aramid fibers.
In a preferred embodiment of the present invention, the width of the intermediate layer, the conductive layer and the heat-resistant layer is in the range of 15-25mm.
A high temperature dust removal filter bag comprises the conductive band convenient to sew.
In a preferred embodiment of the present invention, the electricity removing end of the conductive strip is disposed inside the filter bag, and the connecting portion of the conductive strip is disposed outside the filter bag.
In a preferred embodiment of the present invention, the length of the connecting portion is 200mm.
The beneficial effects of the utility model reside in that:
the utility model provides a conductive band and high temperature dust removal filter bag convenient to sewing changes the combined material who makes through the non-woven fabrics into through the pure metal conducting material with on the original filter bag for conductive band becomes soft easily sewing process, has promoted sewing process's production beat.

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.
A conductive tape for facilitating sewing with reference to fig. 1, characterized by mainly comprising: an intermediate layer 10, a conductive layer 20, and a heat-resistant layer 30.
The middle layer 10 is a mesh belt layer and is used as a base layer for the lapping process of other materials.
The conductive layer 20 is laid on the middle layer 10 by a web former after the opening and untwining process of the conductive fiber. The formed density is 50-60g/m when the composite material is laid 2 The web layers of (a). The conductive fiber may be generally any one of stainless steel fiber and carbon fiber. The stainless steel fibers are preferably 316L stainless steel fiber tow-slit strips. The carbon fiber is generally selected from materials with the carbon content of more than 95 percent, so that the carbon fiber has good electric conduction, heat conduction and electromagnetic shielding performance.
The heat-resistant layer 30 is laid under the middle layer 10 by a web former after being subjected to the opening and fluffing processes. The laying density of the composite material is 50-60g/m 2 . The material of the heat-resistant layer 30 is generally any one of PPS fiber, baoderon, polyimide, and aramid fiber.
After the lapping process is completed on both the conductive layer 20 and the heat-resistant layer 30, it is required to be treated by a spunlace process. The spunlace process is divided into 2 steps, firstly, the first pre-spunlace treatment is carried out, and then the water pressure is increasedAnd carrying out secondary spunlace process treatment. After the treatment by the water jet process, the conductive layer 20, the intermediate layer 10 and the heat-resistant layer 30 form an interwoven, compact three-dimensional structure. The bulk density of the material reaches 100-120g/m 2 The nonwoven hydroentangled material of (a).
Referring to fig. 2 and 3, in order to facilitate sewing of the conductive tape 1, the widths of the intermediate layer 10, the conductive layer 20 and the heat-resistant layer 30 are controlled to be 15-25mm during the forming and lapping processes. When the high-temperature dust removal filter bag 2 is sewn, the electricity removal ends 1a of the 2 conductive belts 1 are fixed on the inner side of the filter bag 2 in parallel through the single needle thread 3, and the connecting parts 1b of the conductive belts 1 are exposed out of the outer side of the filter bag 2. The length control of connecting portion 1b is 200mm, communicates connecting portion 1b when convenient follow-up installation.
