Description

Technical Field

[0001] This utility model relates to the field of mesh fabric production and processing equipment, and in particular to a heating and stretching device for mesh fabric production. Background Technology

[0002] In the production of mesh fabrics, heat stretching is a common process. Heat stretching eliminates the internal stress generated during the stretching process, relaxes the macromolecules to a certain extent, fixes the shape of the woven fibers, improves the dimensional stability of the fabric, and reduces pilling and surface smoothness. Heat stretching can also improve the physical properties of the fabric, such as strength, hand feel, and dyeing properties. However, traditional mesh fabric heat stretching processes use an open heating section, which easily leads to significant heat loss and high energy consumption.

[0003] To address the aforementioned problems, this utility model proposes a heating and stretching device for mesh fabric production.

[0004] Content of utility model

[0005] (1) Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides a heating and stretching device for mesh fabric production, including a processing chamber.

The chamber where the stretching assembly is located is the left chamber, and the chamber where the second pressure roller group is located is the right chamber. A heating assembly is installed in the left chamber, with an electric heating module at its bottom. Two heating assemblies are provided, arranged vertically opposite each other, with both electric heating modules facing the fabric to be stretched. The two heating assemblies are arranged along the conveying direction of the fabric. An exhaust pipe is located at the top of the end of the left chamber, with its top end connected to the bottom of the first transition chamber. An exhaust fan is located in the first transition chamber, which is connected to an exhaust pipe. The exhaust port of the exhaust pipe is located in the second transition chamber.

[0018] (2) Beneficial effects

[0019] This invention reduces heat loss by changing the heating method from external to closed. Transparent curtains and liftable baffles are installed at both ends of the processing chamber to facilitate the feeding of fabric and provide a closed space to minimize heat loss. Excess heat in the left chamber is extracted and then put back into the right chamber for secondary heating of the fabric. This utilizes residual heat, making efficient use of energy, reducing heat loss and production costs. Attached Figure Description

[0033] like Figure 1-2As shown, the heating and stretching device for producing mesh fabric according to this utility model includes a processing chamber 100. Both the inlet and outlet of the processing chamber 100 are equipped with baffles 101. A door frame 102 is located below the baffles 101, and a movable push plate 103 is located on the inner side of the door frame 102. During assembly, the push plate 103 is bolted to the door frame 102. The inner side of the processing chamber 100 is sequentially equipped with a first pressure roller group 104, a stretching assembly 200, and a second pressure roller. Group 108; The stretching assembly 200 includes a support frame 203, the bottom of which is provided with an electric push rod 202. A tension roller 201 is provided on the slider of the electric push rod 202. The fabric to be stretched passes through the first pressure roller group 104 and enters the tension roller 201 for stretching, and then is sent out through the second pressure roller group 108. An upper baffle 106 and a lower baffle 105 for separating the chambers are provided between the stretching assembly 200 and the second pressure roller group 108. The chamber where 0 is located is the left chamber, and the chamber where the second pressure roller group 108 is located is the right chamber. The left chamber is equipped with a heating component 300, and the bottom of the heating component 300 is equipped with an electric heating module 301. There are two heating components 300, which are arranged vertically opposite each other. The electric heating modules 301 are both facing the fabric to be stretched. The two heating components 300 are arranged along the conveying direction of the fabric to be stretched. The top of the end of the left chamber is equipped with an exhaust pipe 401. The top of the exhaust pipe 401 is connected to the bottom of the first transition chamber 400. The first transition chamber 400 is equipped with an exhaust fan 402. The first transition chamber 400 is connected to an exhaust pipe 403. The exhaust port of the exhaust pipe 403 is located in the second transition chamber 500. The second transition chamber 500 is equipped with an air inlet pipe 501 on the side facing the processing chamber 100. The air inlet pipe 501 is located at the bottom of the right chamber. The fabric to be stretched is wound outward on the winding roller 700.

[0034] See details Figure 1The first pressure roller group 104, the second pressure roller group 108, and the third pressure roller group 600 each include two parallel pressure rollers arranged vertically. The baffle 101 is made of high-performance transparent resin material, which facilitates better observation of the conveying of the fabric to be stretched. A transfer roller 107 for transition is also provided between the tension roller 201 and the second pressure roller group 108. The transfer roller 107 is located in the middle of the upper baffle 106 and the lower baffle 105. An electrically controlled valve 404 is provided on the air outlet pipe 403 to facilitate control of the flow of hot air. The second transition chamber 500 is installed on the pressure roller group 600. At the bottom of the work chamber 100, the top of the air inlet pipe 501 is provided with an air inlet 502 to facilitate the uniform expansion of the area where hot air enters. Between the second pressure roller group 108 and the winding roller 700, a third pressure roller group 600 is also provided to guide the fabric, so that the fabric can be effectively compacted when it is fed out. In addition, there are three stretching components in the left chamber, two of which are located at the bottom, and the remaining one is located in the middle of the two stretching components and above them. The three stretching components stretch the fabric to be stretched evenly, which facilitates the multi-directional stretching effect.

[0035] Working Principle: In use, the fabric enters through the gap between the curtain and the baffle at the feed end of the processing chamber. It should be noted that the baffle can move up and down within the door frame (this is the same at both the front and back of the processing chamber). This is to facilitate the formation of a closed space and minimize heat overflow. After the baffle moves to a specific position, it is locked in place with bolts, reducing the heat overflow opening and minimizing energy loss. The fabric then enters the second pressure roller group along with the first pressure roller group and the stretching assembly. Heating and stretching are performed at the stretching assembly. Heating is mainly achieved through an electric heating module within the heating assembly. This electric heating module is existing technology, primarily using the principle of electric heating to increase the temperature. The heating assembly is arranged parallel to the direction of fabric conveying, maximizing the direct effect of heat on the fabric. (See attached diagram). Figure 1 This solution provides three stretching components: a lower stretching component symmetrically positioned on the left and right sides, and a stretching component positioned in the upper middle. While stretching can also be achieved with a single stretching component, the three stretching components in this solution ensure even stretching of the fabric from top to bottom, resulting in a better stretching effect. This allows for simultaneous heating and stretching. Excess hot air rises and is drawn from the left chamber by the exhaust fan in the first transition chamber. The heat then flows through the exhaust pipe and outlet pipe to the second transition chamber, where it is released back into the right chamber, directly acting on the fabric again. This achieves a two-stage heating effect, reducing energy waste and improving energy utilization.

[0036] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
