Description

Technical Field

[0001] The utility model relates to the technical field of textiles and coatings, in particular to a waterless dust removal device for a stenter setting machine. Background Art

[0002] A stenter is a device commonly used in the textile and coating industries for shaping and stretching fabrics, films or coating materials. It mainly changes the physical properties and dimensional stability of the materials through steps such as stretching, heating and cooling. When using a stenter to process fabrics, the fiber material will produce tiny particles due to breakage, friction or peeling during the processing. These yarn dust particles are released from the surface of the fabric or the fiber material during the operation of the stenter, forming yarn dust. Yarn dust is a phenomenon that is difficult to completely avoid during the textile processing process. Therefore, in order to ensure the health and safety of employees, in addition to the operator taking appropriate protective measures, the stenter is also usually equipped with a dust removal device.

[0003] Patent document 1 (CN104032524B, application date 2014.06.11) discloses a dust removal device for a stenter setting machine, which has a dust removal belt (a mesh-shaped filter guide belt) entering and exiting the stenter setting machine. The dust removal belt is treated by two processes: dust blowing with an air blowing pipe and water washing with a water spray pipe. The disadvantages are that dust blowing will generate dust, water washing will generate water mist, and the effect on fine hair is not good.

[0004] Patent document 2 (CN104862916B, application date 2015.05.15) discloses a waterless cleaning device for dust removal belt of stenter setting machine, which improves the above-mentioned defects of Patent document 1. The dust removal belt is cleaned by brush roller, dust hood and negative pressure dust suction. The dust on the mesh filter guide belt can be removed in one process without generating dust and water mist. At the same time, the fine hair squeezed together can also be removed smoothly. However, compared with Patent document 1, Patent document 2 has the problem that the dust removal belt is not cleaned thoroughly, resulting in poor dust removal effect of stenter setting machine.

[0018] The utility model is further described below in conjunction with the embodiments and drawings.

[0019] In the embodiment, Figures 1 to 3 As shown, a waterless dust removal device for a stenter setting machine comprises: a dust suction belt 1, which is a mesh conveyor belt, entering and exiting the oven of the stenter setting machine and passing through from under the fabric in the oven; an active roller 2, driving the dust suction belt 1 to move; a brush roller 3, tangent to the active roller 2, and the dust suction belt 1 is clamped between the active roller 2 and the brush roller 3; a contact arc m, which is the contact part between the dust suction belt 1 and the active roller 2; an axial line n, which is the axial line between the active roller 2 and the brush roller 3; a cover shell 4, which is a accommodating space for the contact arc m and the brush roller 3; a suction pipe 5, which is disposed in the cover shell 4 and connected to a vacuum dust pump; the contact arc m is arranged axially symmetrically with respect to the axial line n. In this embodiment, the dust removal belt 1 is cleaned by means of a brush roller 2, a cover shell 4 and negative pressure dust suction. The brush roller 2 and the cover shell 4 are arranged at the contact arc m between the dust removal belt 1 and the active roller 2, that is, the dust removal belt 1 is cleaned at the reverse bending part. This can significantly improve the thoroughness of cleaning, and there will be no dust, water mist and other phenomena. In addition, the dust removal device is relatively simple, thereby ensuring the dust removal effect of the stenter setting machine.

[0020] In the embodiment, Figure 1 As shown, the rotation direction of the brush roller 3 is the same as that of the active roller 2. This arrangement can make the brush roller 3 and the dust removal belt 1 have a greater relative speed, which helps to better clean the dust removal belt 1.

[0021] In the embodiment, Figure 1 , 2 As shown, the contact arc m has an angle greater than 150°, that is, Figure 2 The angle α is greater than 150°. This structure can accommodate a larger dust removal belt 1 within the range of the housing 4, and achieve a better dust removal effect under the effect of negative pressure dust suction.

[0022] In the embodiment, Figure 1 , 2As shown, the axial height of the brush roller 3 is lower than the axial height of the active roller 2. Specifically, it also includes: a first guide roller 6, arranged in the direction of the dust suction belt 1 relative to the active roller 2; a second guide roller 7, arranged in the direction of the dust suction belt 1 relative to the active roller 2; the first guide roller 6 and the second guide roller 7 are located in the same vertical plane, and the active roller 2 and the second guide roller 7 are located in the same horizontal plane; the dust suction belt 1 is from the first guide roller 6, around the active roller 2, to the second guide roller 7. This structure allows the cover 4 to be tilted upward, which can better receive the fallen yarn dust and avoid the generation of dust.

[0023] In the embodiment, Figure 1 , 3 As shown, it also includes: a dust box 8, which is a chamber for the dust belt 1, the active roller 2, the brush roller 3, the cover 4, the suction pipe 5, the first guide roller 6 and the second guide roller 7; and a return air pipe 9, which is arranged in the dust box 8 and communicates with the air. In addition, the active roller 2 is densely covered with a number of air holes 201, and the two ends of the active roller 2 are end plates 202 with holes. This structure can form flowing wind on the mesh of the dust belt 1, so that the yarn dust of the dust belt 1 can be blown off better, which can produce better effects than negative pressure dust collection.

[0024] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation methods of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
