Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of copper ion antibacterial fabric production equipment, in particular to a drying device for copper ion antibacterial fabric. Background Art
[0002] Copper ion antibacterial fabrics are made by attaching copper ions with antibacterial properties to the fabric. During the production process, raw materials such as polyester fibers are usually treated with a copper ion finishing solution, allowing the copper ions to attach to the fibers in the form of "microcapsules" before being woven into fabrics. The treated fabrics are then placed in a drying oven for drying, which allows the fabrics to be quickly dried and shaped. Existing drying equipment directly dries and heats the fabrics through drying elements. This can dry and shape the outer surface of the fabric, but the interior of the fabric remains moist, resulting in uneven dispersion of copper ions on the fabric. Controlling the drying temperature can cause copper ions to agglomerate when the drying temperature is too high, while too low a drying temperature can affect the penetration of the antibacterial agent, seriously affecting the subsequent production quality of the fabric. Utility Model Content
[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing drying equipment directly dries and heats the fabric through the drying element, the outer surface of the fabric can be dried and shaped, while the inside of the fabric is still wet, resulting in uneven dispersion of copper ions on the fabric, and if the drying temperature is controlled, when the drying temperature is too high, the copper ions may agglomerate, and when the drying temperature is too low, the penetration effect of the antibacterial agent may be affected, seriously affecting the subsequent production quality of the fabric. A drying device for copper ion antibacterial fabric is now provided.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a drying device for copper ion antibacterial fabrics, comprising a drying box, an air extraction pump heating element and two preheating nozzles, wherein the drying box has a first cavity, the drying box is provided with an input port and an output port connected to the first cavity, the heating element is arranged in the first cavity, the two preheating nozzles are arranged on both sides of the fabric and are located in the first cavity, the input end of the air extraction pump is connected to the first cavity, the output end of the air extraction pump is respectively connected to the two preheating nozzles, and the preheating nozzles and the heating element are arranged in sequence along the fabric conveying direction;
[0005] The two preheating nozzles each include an outer shell, a second cavity is provided in the outer shell, a partition is provided in the second cavity for dividing the second cavity into two upper and lower cavities separated from each other, a first air inlet connected to the upper cavity is provided on the outer shell, the first air inlet is used to input the air source of the vacuum pump, a first air outlet is provided at one end of the outer shell close to the fabric, the first air outlet is connected to the upper cavity, a second air inlet is provided at one end of the outer shell close to the fabric, the second air inlet is connected to the lower cavity, a second air outlet is provided on the outer shell, the second air outlet is connected to the lower cavity, the first air outlet on one of the two preheating nozzles is arranged corresponding to the second air inlet on the other preheating nozzle. Compared with the existing technology, the vacuum pump in this scheme extracts the hot gas in the first cavity, and sprays and preheats the two sides of the fabric through two preheating nozzles. The first air outlet on one of the two relatively set preheating nozzles is set corresponding to the second air inlet on the other. The gas that passes through the fabric can be collected through the second air inlet, and the gas that does not pass through the fabric can also enter through the second air inlet and finally be discharged through the second air outlet, thereby preheating the fabric, improving the subsequent drying efficiency, and ensuring that the copper ions on the fabric are evenly dispersed.
[0006] To prevent the heat in the first cavity from being rapidly discharged, and to maintain the heat within the first cavity, preferably in some embodiments, the flow area of the input port gradually increases from one end to the other along the fabric conveying direction, while the flow area of the output port gradually decreases from one end to the other along the fabric conveying direction. External gas does not experience a pressure differential when passing through the input port, while gas within the first cavity does experience a pressure differential when passing through the output port. This pressure differential between the input and output ports better ensures that heat within the first cavity is retained and prevented from being rapidly discharged.
[0007] In order to prevent heat from accumulating in one place in the first cavity, in some preferred embodiments, the second air outlet is arranged toward the output port. The gas ejected through the second air outlet disturbs the flow in the first cavity, ensuring uniform heat distribution in the first cavity and avoiding heat accumulation and uneven heat distribution.
[0008] Since the humidity of the gas in the first cavity is high, in order to better preheat the fabric, in some preferred embodiments, a drying mechanism is provided on the input end of the vacuum pump to absorb moisture and reduce the humidity of the gas ejected from the preheating nozzle.
[0009] In order to realize the drying mechanism, some preferred embodiments include a drying box fixedly mounted on the drying box, a breathable drying plate is provided in the drying box, the input end of the vacuum pump is connected to the drying box, and the drying box is connected to the first cavity.
[0010] In order to quickly exhaust the gas from the first gas outlet, in some preferred embodiments, a plurality of guide plates for quickly guiding the gas are provided in the first gas outlet.
[0011] In some preferred embodiments, a plurality of the guide plates are distributed in a spiral along the axial direction of the first air outlet.
[0012] In some preferred embodiments, the flow area of the second air inlet gradually decreases from the outside toward the lower cavity.
[0013] In some preferred embodiments, the first air outlet is arranged between two adjacent second air inlets.
[0014] The beneficial effects of the utility model are as follows: when the copper ion antibacterial fabric drying device of the utility model is in use, the vacuum pump extracts the hot gas in the first cavity, and sprays and preheats the two sides of the fabric respectively through the two preheating nozzles, and the first air outlet on one of the two relatively arranged preheating nozzles is set corresponding to the second air inlet on the other, and the gas that passes through the fabric can be collected through the second air inlet, and the gas that does not pass through the fabric can also enter through the second air inlet and finally be discharged through the second air outlet, so as to preheat the fabric, improve the subsequent drying efficiency, and ensure that the copper ions on the fabric are evenly dispersed, avoiding the existing drying equipment directly drying and heating the fabric through the drying element, and the outer surface of the fabric can be dried and shaped, while the inside of the fabric is still wet, resulting in uneven dispersion of copper ions on the fabric. If the drying temperature is controlled, when the drying temperature is too high, it may cause copper ions to agglomerate, and when the drying temperature is too low, it may affect the penetration effect of the antibacterial agent, seriously affecting the subsequent production quality of the fabric.

[0031] The second air outlet 407 is disposed toward the output port 103 .
[0032] The flow area of the input port 102 gradually increases from one end to the other end along the conveying direction of the fabric 8, and the flow area of the output port 103 gradually decreases from one end to the other end along the conveying direction of the fabric 8.
