Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fabric heat setting equipment, specifically a novel air duct structure for a fabric heat setting device. Background Technology
[0002] Heat setting is a crucial step in fabric production, aiming to achieve stable dimensions, a good hand feel, and a pleasant appearance by heating and cooling the fabric. The air duct structure within the heat setting device has a vital impact on the heat setting effect; a well-designed air duct structure ensures that hot air is evenly distributed across the fabric, thereby improving the quality and efficiency of heat setting. Existing fabric heat setting devices have several shortcomings in their duct structure during practical use. For example, uneven airflow distribution within the duct leads to inconsistent heating of different parts of the fabric, affecting the heat setting effect; the duct has poor insulation performance, resulting in significant heat loss, which not only increases energy consumption but may also cause excessively high temperatures around the duct, posing a safety hazard; furthermore, the existing duct structure is inconvenient to clean and maintain, easily accumulating dust and debris, affecting the normal operation of the duct. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a novel air duct structure for a fabric heat setting device, which can reduce heat loss and lower energy consumption.
[0004] The technical solution of this utility model is as follows: a novel air duct structure for a fabric heat setting device, comprising an air duct body, an air inlet at one end of the air duct body and an air outlet at the other end, a guide plate inside the air duct body, the guide plate being inclined and multiple guide plates being evenly distributed along the length of the air duct body; an insulation layer made of heat-insulating material being provided on the outer wall of the air duct body; and a cleaning port at the bottom of the air duct body, with an openable sealing cover at the cleaning port. Preferably, the angle between the guide plate and the inner wall of the air duct body is 30-60 degrees. By setting the inclined guide plate, the airflow can be guided and diverted, so that the airflow is more evenly distributed in the air duct. Preferably, the insulation layer has a thickness of 5-10 cm, which can effectively reduce heat loss and improve the insulation performance of the air duct. Preferably, the edge of the sealing cover is provided with a sealing ring, which can ensure the sealing performance of the cleaning port and prevent dust and debris from entering the interior of the air duct body.
[0005] Preferably, the insulation layer is a multi-layer composite structure, including an inner heat insulation layer, a middle reflective layer, and an outer protective layer.
[0006] The beneficial effects of this utility model are as follows: This utility model provides a novel air duct structure for a fabric heat setting device. By setting multiple inclined guide plates inside the air duct body, the airflow can be rationally guided, ensuring that the airflow is evenly distributed within the air duct, thereby ensuring uniform heating of the fabric and improving the heat setting effect. By setting a heat insulation layer on the outer wall of the air duct body, heat loss can be reduced, energy consumption can be lowered, and excessively high temperatures around the air duct can be avoided, thus improving safety. By setting a cleaning port and an openable sealing cover at the bottom of the air duct body, it is convenient to clean and maintain the interior of the air duct, keeping the air duct unobstructed and extending the service life of the equipment. Attached Figure Description
[0007] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0008] Figure 1 This is a schematic diagram of the structure of this utility model.
[0009] Figure 2 This is a schematic diagram of the insulation layer. Detailed Implementation
[0010] The technical solution of this utility model will be clearly and completely described below through specific embodiments.
[0011] refer to Figures 1-2 This invention discloses a novel air duct structure for a fabric heat setting device, comprising an air duct body 1, with an air inlet 2 at one end and an air outlet 3 at the other end. Multiple guide plates 4 are inclined and evenly distributed along the length of the air duct body 1. An insulation layer 5, made of heat-insulating material, is provided on the outer wall of the air duct body 1. A cleaning port 6 is located at the bottom of the air duct body 1, and an openable sealing cover 7 is provided at the cleaning port 6. The sealing cover 7 can be installed independently or connected to the cleaning port 6 via a hinge.
[0012] The angle between the guide plate 4 and the inner wall of the duct body 1 is 45 degrees. This angle setting can better guide and divert the airflow, making the airflow more evenly distributed within the duct. The insulation layer 5 is 8 cm thick, which can effectively block heat loss, improve the insulation performance of the duct, and reduce energy consumption. The sealing cover 7 and the cleaning port 6 are connected by a hinge for easy opening and closing. The edge of the sealing cover 7 is provided with a sealing ring to ensure the sealing effect of the cleaning port 6 and prevent dust and debris from entering the interior of the duct body 1. The insulation layer 5 is a multi-layer composite structure, including an inner heat insulation layer 51, a middle reflective layer 52, and an outer protective layer 53.
[0013] The insulation layer is made of rock wool, glass wool or polyurethane foam, the reflective layer is aluminum foil or metal reflective film, and the protective layer is high temperature and corrosion resistant fiberglass or metal plate. The insulation layer 5 is fixedly connected to the outer wall of the air duct body 1 by adhesive or fastener, and a sealing strip is provided between adjacent insulation layer modules.
[0014] In this embodiment, the insulation layer 5 adopts a modular splicing structure. The size of each insulation module is adapted to the outer surface of the air duct body 1. An L-shaped metal buckle is provided on the back of the module. A slot that cooperates with the buckle is opened on the corresponding position of the outer side wall of the air duct body 1. The insulation layer 5 can be quickly installed by the snapping of the buckle and the slot. The splicing gap between adjacent insulation modules is filled with high-temperature resistant sealant to ensure the overall sealing of the insulation layer. During installation, first clean and apply adhesive to the outer wall of the main body of the air duct 1, then attach the heat insulation layer to the surface of the air duct, then lay the reflective layer and fix it with rivets, and finally snap the protective layer module into the slot with clips. Fill and compact the joints of the modules with sealant to form a complete heat insulation structure.
[0015] Working Principle: When using this invention, hot air enters the air duct body 1 through the air inlet 2, passes through multiple inclined guide plates 4, which guide and divert the airflow, ensuring even distribution within the air duct body 1. The air then exits through the air outlet 3, performing heat setting on the fabric. Because the outer wall of the air duct body 1 is equipped with an insulation layer 5, heat loss is reduced, maintaining a stable temperature within the air duct and improving thermal efficiency. When cleaning the interior of the air duct body 1 is required, the sealing cover 7 is opened, and the interior of the air duct can be cleaned through the cleaning port 6, maintaining unobstructed airflow and ensuring the normal operation of the equipment.
[0016] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
