Description

TECHNICAL FIELD

[0001] The utility model relates to the field of textile processing, more specifically, it relates to a fabric printing preheating structure. BACKGROUND

[0002] In the textile printing and dyeing industry, the pretreatment step before fabric printing is very important, and the preheating link is particularly critical. Preheating not only improves the absorption capacity of fabric to printing paste, ensures the color of the printed pattern, and clearly defines the edges, but also effectively shortens the drying time after printing, avoiding problems such as color bleeding or deformation of the fabric due to incomplete drying during stacking or subsequent processing.

[0003] The existing preheating structure is generally arranged in the horizontal direction. In the production workshop of a textile printing and dyeing enterprise, the space resources are often very limited, and the horizontally arranged preheating equipment occupies a large production area. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a fabric printing preheating structure.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a fabric printing preheating structure, comprising two support plates and three guide rollers located between the two support plates, the guide rollers are rotatably connected with the support plates, one of the guide rollers is higher than the other two guide rollers, the three guide rollers guide the fabric to form a U shape, and a heating element is arranged between the three guide rollers.

[0006] The utility model is further provided as follows: a cover is arranged on the support plate, a heat preservation cavity is formed between the cover and the two support plates, and the three guide rollers and the heating element are located in the heat preservation cavity.

[0007] The utility model is further provided as follows: the cover and the support plate are detachably connected.

[0008] The utility model is further provided as follows: a recess is formed on the side of the support plate away from the other support plate, the recess penetrates the top surface of the support plate, and the cover is embedded in the recess.

[0009] The utility model is further provided as follows: the heating element has a hollow structure, a plurality of through holes communicating with the heat preservation cavity are arranged on the surface of the heating element, and an air flow channel communicating with the heating element is arranged on the support plate.

[0010] The utility model is further provided as follows: the thickness of the heating element is less than the gap width between the two guide rollers at the bottom end.

[0011] In summary, this utility model has the following beneficial effects: the fabric path is zigzag-shaped, the heating element is surrounded by the fabric, and the fabric is fully preheated. At the same time, because the fabric is preheated in an upward movement path, the production area is saved. The cover reduces the heat exchange between the insulation cavity and the outside, reduces the heat loss generated when preheating the fabric, saves thermal energy and improves preheating efficiency.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A fabric printing preheating structure, such as Figure 1 , Figure 2 As shown, it includes two support plates 1 and three guide rollers 2 located between the two support plates 1. The guide rollers 2 are rotatably connected to the support plates 1. One guide roller 2 is higher than the other two guide rollers 2. The three guide rollers 2 guide the fabric in a Z-shape. A heating element 3 is provided between the three guide rollers 2.

[0017] Specifically, the two guide rollers 2 located at the bottom of the support plate 1 are at the same horizontal height, and the other guide roller 2 is located at the top of the support plate 1. The fabric first passes through the lower guide roller 2, then around the higher guide roller 2, and finally passes through the lower guide roller 2, so that the path of the fabric is in the shape of a zigzag. The heating element 3 is surrounded by the fabric, which fully preheats the fabric. At the same time, because the fabric is preheated in the upward movement path, the production area is saved.

[0018] like Figure 1 , Figure 2 As shown, a cover 4 is provided on the support plate 1, and a heat preservation cavity is formed between the cover 4 and the two support plates 1. The three guide rollers 2 and the heating element 3 are all located in the heat preservation cavity. The cover 4 is detachably connected to the support plate 1. A groove 5 is provided on the side of the support plate 1 away from the other support plate 1. The groove 5 penetrates the top surface of the support plate 1, and the cover 4 is embedded in the groove 5.

[0019] Specifically, the cover 4 is integrally formed with protrusions corresponding to the grooves 5 on both sides, the cover 4 is clamped on the support plate 1 from top to bottom through the grooves 5, the cover 4 reduces heat exchange between the warm cavity and the outside, reduces heat loss generated when preheating the fabric, saves heat energy while improving the preheating efficiency, when the fabric is placed on the guide roller 2, the cover 4 is disassembled, after the fabric is laid, the cover 4 is clamped on the support plate 1, the efficiency of fabric laying is improved.

[0020] As shown in Figure 1 , Figure 2 The heating element 3 is in a hollow structure, a plurality of through holes 6 communicating with the warm cavity are arranged on the surface of the heating element 3, and an airflow channel 7 communicating with the heating element 3 is arranged on the support plate 1.

[0021] Specifically, the heating element 3 is connected with a hot air blower through the airflow channel 7, the hot air blower inputs high-temperature airflow into the heating element 3, then the high-temperature gas enters the warm cavity through the through holes 6 to heat the fabric, the thickness of the heating element 3 is small, and the heating element 3 is parallel to the fabric on one side, avoiding direct contact between the heating element 3 and the fabric and damage to the fabric.

[0022] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution belonging to the idea of the present application is within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
