Description

Technical Field

[0001] The invention relates to the field of drying equipment, and in particular to a continuous drying device and a drying method for producing reflective fabrics. Background Art

[0002] Reflective fabric is a special fabric, which is mainly used to make work clothes, professional clothes, fashion, shoes and hats, bags, personal protective equipment, outdoor products, etc. with reflective effects.

[0003] During the drying process of reflective cloth, the equipment provides hot air or hot air flow to evaporate the moisture and solvent on the surface of the reflective cloth. The raw materials used in the production process of reflective cloth, such as fibers and yarns, contain impurities or short fibers. These impurities are easy to form dandruff during the processing process. In addition, production equipment such as looms and cutting machines may generate friction during operation, causing fiber breakage and the formation of dandruff. For lamp heating or wind heating, the dandruff during drying has the risk of being ignited by the heat source. The generated water vapor will be discharged in time to prevent the cloth from getting damp again, but after being dispersed in the workshop, it will affect the production environment, product quality, and the life of peripheral equipment, etc., bringing adverse effects.

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0033] like Figure 1-Figure 8 A continuous drying device for producing reflective fabrics shown in the figure comprises a base frame 1, a hot air mechanism is arranged on the inner side of the base frame 1, a conveying mechanism is arranged on the inner side of the base frame 1 near the upper end, side panels 2 are fixedly installed on the two edges of the upper surface of the base frame 1, angle panels 4 are fixedly installed on the upper ends of the two side panels 2, a circular tube 7 is fixedly installed at the connection position between the angle panels 4 and each side panel 2, a through opening 11 is opened on the upper surface of the circular tube 7, arc-shaped tail panels 10 are fixedly connected to the lower surface of the angle panels 4 near the edges on both sides, an arc-shaped top 9 is fixedly connected to the middle position of the lower surface of the angle panels 4, a plurality of rotating sleeves 15 are rotatably installed on the inner side of the circular tube 7, a plurality of guide blades 14 arranged in a ring array are fixedly arranged on the outer surface of the rotating sleeve 15, and a discharge portion is arranged near the front end of the lower surface of the circular tube 7;

[0034] The lower edge of the arc-shaped tail plate 10 is close to the upper part of the port of the through-port 11. After the lower surface of the arc-shaped tail plate 10 drains the water to the surface of the guide vane 14 below, the water flow causes the guide vane 14 to rotate downward; the guide vane 14 rotates so that the water flow at the inner bottom surface of the circular tube 7 is pushed forward.

[0035] like Figure 1 , Figure 2 As shown, the hot air mechanism includes a base 27 fixedly mounted on the inner bottom surface of the base frame 1, a fan 28 fixedly mounted on the upper surface of the base 27, a heating mesh plate 29 fixedly mounted on the air inlet port of the fan 28, and an air outlet port of the fan 28 pointing upwards. The heating mesh plate 29 is also called an electric heating mesh plate, which is an electric heating element, usually composed of electric heating wire, metal belt and insulating material. Its working principle is to convert electrical energy into thermal energy, thereby heating the surrounding environment. After heating, the hot air is sucked out by the fan 28 to dry the cloth.

[0036] The conveying mechanism includes a plurality of conveying rollers 30 rotatably mounted on the inner side of the base frame 1 and near the upper end. In use, the cloth is conveyed over the conveying rollers 30 , and the dried cloth is usually rolled into a roll by a rolling device.

[0037] like Figure 1 As shown, the front and rear ends of the corner panels 4 and the side panels 2 are respectively fixedly connected with a shielding plate 6. An exhaust port 5 is provided on the outer surface of the shielding plate 6 near the upper end. The exhaust port 5 can be connected to a ventilation pipe to discharge part of the water vapor to the outside of the workshop. Since most of the hair scraps are processed, too many impurities will not accumulate in the ventilation pipe, thereby extending the maintenance period of the ventilation pipe. Several observation windows 3 are installed on the side surface of the side panel 2 to observe the condition of the inner fabric.

[0038] like Figure 4As shown, the discharge part includes a discharge pipe 24 fixedly embedded in the lower surface of the circular tube 7, and the lower end of the discharge pipe 24 is fixedly connected to a drainage pipe 25. The length and inclination of the drainage pipe 25 can be designed as needed to centrally recover water flow and hair debris impurities.

[0039] The inner side of the rotating sleeve 15 is rotatably connected with a through shaft 17, and threaded columns 16 are respectively extended from the front and rear ends of the through shaft 17. The outer surface of each threaded column 16 is sleeved with an end shaft 12 that matches with the thread, which is convenient for assembly between the end shaft 12 and the threaded column 16. The outer surface of each end shaft 12 is fixedly sleeved with a fixing plate 13, and the upper end of the fixing plate 13 is fixedly connected to the inner wall of the circular tube 7. In this way, the rotating sleeve 15 is arranged in a plurality of pieces, and each is rotatably installed independently to ensure that the rotating sleeve 15 can rotate when water drips.

[0040] The specific structure of the rotating sleeve 15 is as follows: the end shaft 12 is inserted into the port of the rotating sleeve 15, and an annular groove 18 is provided between the end shaft 12 and the through shaft 17. A bearing sleeve 19 is movably mounted on the inner side of the annular groove 18. The outer surface of the bearing sleeve 19 is fixedly mounted on the inner wall of the rotating sleeve 15 through a mounting bolt 20. After unscrewing the mounting bolt 20, the disassembly of the bearing sleeve 19 can be completed. The structural design is reasonable and easy to assemble and overhaul later. A bearing frame 21 is provided on the inner side of the bearing sleeve 19. A plurality of balls 22 are movably embedded on the outer surface of the bearing frame 21. The bearing frame 21 maintains the position of the balls 22 to prevent them from being removed. The surface of the balls 22 contacts the bearing sleeve 19 and the annular groove 18, which effectively reduces the resistance and ensures that the water flow can rotate the guide vane 14. A sealing ring 23 is fixedly embedded on the inner wall of the rotating sleeve 15 near the port. The sealing ring 23 can effectively reduce the infiltration of water and hair into the gap.

[0041] The outer surface of the circular tube 7 is fixedly connected with a connecting plate 8, which is fixedly connected to the upper end of the side plate 2. The connecting plate 8 is used to increase the stability of the installation of the circular tube 7. A maintenance ladder 31 is fixedly installed on one side of the base frame 1 and the connecting plate 8 to facilitate climbing and maintenance by workers.

[0042] A continuous drying method for producing reflective fabric is also proposed, which is carried out using the above drying device and includes the following steps:

[0043] S1, conveying the reflective cloth through the surface of the conveying mechanism;

[0044] S2, turning on the hot air mechanism to dry the reflective fabric between the two side panels 2;

[0045] S3. Connect a container below the discharge portion.

[0046] During the drying process, the air sucked by the fan 28 is heated by the heating mesh plate 29 to form hot air which is then blown upward, so that the cloth passing over the conveying roller 30 is heated and dried. The water vapor generated in this process moves upward with the flow of air, and is partially condensed after encountering the angle plate 4. At the same time, the hair debris in the air is also adhered to by the water on the surface of the angle plate 4. As the amount of water on the surface of the angle plate 4 increases, it will flow down along the surface. The transition at the arc top 9 is smooth, which reduces the accumulation of water. The water flowing downward is guided by the arc tail plate 10 and falls into the through port 11, and falls onto the surface of the guide blade 14, causing the guide blade 14 to rotate. The rotation will push the water accumulated in the circular tube 7 forward, and finally cause the water and hair debris to fall to the discharge pipe 24, and can be drained away. This drying technology can effectively prevent hair debris from falling to the heat source below, effectively reduce the risk of fire, and effectively recycle moisture, which is beneficial to protecting the environment of the processing workshop.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention. These changes and improvements fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
