Description

Technical Field

[0001] The utility model relates to fabric drying equipment, in particular to a denim fabric drying device. Background Art

[0002] After the padding process, denim fabrics need to be dried, for which a fabric drying device is needed. Compared with ordinary fabrics, denim fabrics are relatively poor in water absorption. This is because denim is usually rough and does not absorb water easily. However, this does not mean that denim fabrics are easier to dry than ordinary fabrics, because denim fabrics have a thicker fabric structure and a higher fabric density than ordinary fabrics, so more energy is consumed to fully heat denim fabrics. Although existing fabric drying devices use vacuum to accelerate water evaporation, more of them use heat sources to heat air flow to dry fabrics. Because denim fabrics are thicker and have a higher fabric density, it takes more time to fully heat denim fabrics. Therefore, using the same fabric drying equipment, it takes longer and is less efficient to dry denim fabrics than ordinary fabrics. Summary of the invention

[0003] The utility model provides a denim fabric drying device, which solves the problem in the prior art that drying the denim fabric is more time-consuming and less efficient.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: a denim fabric drying device, comprising a dryer body, characterized in that: the dryer body comprises a dryer cover with a hollow interior, an electric heating component arranged in the dryer cover, an exhaust system and a traction roller group for traction fabric, the dryer cover is provided with a fabric introduction groove and a fabric outlet groove, the exhaust system comprises an exhaust fan fixed on the dryer cover, an exhaust pipe connected to the exhaust port of the exhaust fan and an air inlet arranged on the dryer cover, the air inlet of the exhaust fan is connected with the interior of the dryer cover; the drying device also comprises a fabric preheating component, the fabric preheating component comprises a preheating cover and a preheating pipe arranged inside the preheating cover, the preheating cover is provided with a fabric inlet and a fabric outlet, the preheating pipe is a hollow metal pipe, which comprises a plurality of horizontal parallel spaced transverse pipes and a curved pipe connecting adjacent transverse pipes, one end of the preheating pipe is connected with the exhaust pipe, and the other end is arranged to extend out of the preheating cover, and the fabric flows through each transverse pipe in a continuous S shape.

[0005] In the process of transferring the fabric to be dried from other prior fabric production equipment to the present invention, the temperature of the fabric will continue to drop. Therefore, when the fabric enters the present invention, there is a large temperature difference between its own temperature and the drying temperature in the dryer cover. For this reason, the present invention adds a fabric preheating component, and the exhaust system can continuously draw hot and humid air from the dryer cover, pump it into the preheating pipe, and finally discharge it. After the preheating pipe is heated by hot air, it can preheat the fabric flowing through its outer surface, so that the denim fabric can be heated in advance. When the denim fabric flows out of the fabric preheating component and enters the dryer cover, the temperature difference between the fabric and the ambient temperature is small, and the fabric can be quickly heated to the set temperature and dried by hot air. Therefore, the present invention can make better use of heat, reduce energy loss, preheat the fabric in advance, reduce the residence time of the fabric in the dryer body, and improve the production efficiency of the fabric.

[0006] Furthermore, the electric heating assembly includes a plurality of mounting racks fixed in the dryer cover at intervals in the horizontal direction and a plurality of heating modules fixed on the mounting racks in an array, and the fabric flows through each mounting rack in a continuous S-shape under the traction of the traction roller group. Such a structural design can improve the space utilization rate, and within a certain range of equipment size, the moving length of the fabric in the dryer body can be increased as much as possible, and the front and back sides of the fabric are both within the thermal radiation irradiation range of the heating module, which is conducive to improving the drying efficiency.

[0007] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model adds a fabric preheating component, and the exhaust system can continuously draw hot and humid air from the dryer cover and pump it into the preheating pipe. After the preheating pipe is heated by the hot air, the fabric flowing through its outer surface can be preheated, so that the denim fabric can be heated in advance. When the denim fabric flows out of the fabric preheating component and enters the dryer cover, the fabric can be quickly heated to the set temperature and dried by the hot air. Therefore, the utility model can better utilize heat, reduce energy loss, preheat the fabric in advance, reduce the residence time of the fabric in the dryer body, and improve the production efficiency of the fabric.
