Description

Technical Field

[0001] This invention relates to the field of fabric drying, and more particularly to a hot air circulation drying system for ultra-fine porous woven fabrics. Background Technology

[0002] In the textile printing, dyeing, and finishing process, fabric drying is a crucial step, and its efficiency and quality directly affect the quality of the final product and production efficiency. Traditional fabric drying methods mostly employ direct hot air drying; While direct hot air drying can achieve a certain degree of drying effect, the hot air is directly discharged after contact with the fabric, resulting in a large amount of heat energy being lost into the environment without being fully utilized, causing a great waste of energy and increasing production costs. In addition, during drying, the outer side of the fabric is easily dried while the inner side is prone to forming a damp layer, resulting in poor overall uniformity of drying. How to solve these problems needs to be considered. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hot air circulation drying system for ultra-fine porous woven fabrics. This drying system employs circulation drying, which reduces heat loss. Furthermore, during the drying process, airflow can be used to intermittently blow on the upper and lower sides of the fabric, utilizing the fabric's elasticity to achieve fabric shaking. This mechanical action disrupts the moisture distribution on the fabric surface, promoting the migration of internal moisture to the surface and improving the overall drying speed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A hot air circulation drying system for ultra-fine porous woven fabric includes a base plate with a housing fixedly connected to its upper end. A processing chamber is located inside the housing, with rectangular openings on both the left and right inner walls of the processing chamber. A fabric body passes through both rectangular openings. A drying mechanism includes a U-shaped plate disposed inside the processing chamber, with two horizontal portions of the U-shaped plate positioned above and below the fabric body. Each horizontal portion of the U-shaped plate contains a cavity, and air-blowing strips are formed on the opposite sidewalls of the cavities. These air-blowing strips intermittently blow out hot air, utilizing the elasticity of the fabric body to achieve shaking and improve the drying effect. A gas circulation mechanism is used for circulating drying. A filtration mechanism is used to filter the fibers produced during drying.

[0005] Preferably, two support rollers are rotatably connected between the inner walls of the front and rear sides of each rectangular opening, and the main body of the fabric is located between the two support rollers.

[0006] Preferably, the gas circulation mechanism includes a circulating hot air blower installed on the upper end of the housing, a filter groove is provided at the bottom of the processing chamber, the air inlet end of the circulating hot air blower extends into the filter groove, a drying box is installed at the upper end of the housing, and the blower end of the circulating hot air blower communicates with the rear space of the drying box.

[0007] Preferably, a fixing plate is fixedly connected to the front side of the U-shaped plate. The fixing plate has two communication ports that communicate with corresponding cavities. A hollow disc is provided on the front side of the fixing plate and fits therewith. Multiple air vents are provided on the rear side of the hollow disc. A rotating tube is connected to the front side of the hollow disc. The front end of the rotating tube extends to the outside and is connected to a connecting tube through a rotary joint. The other end of the connecting tube is connected to the front space of the drying oven. An L-shaped plate for supporting the connecting tube is installed on the front side of the shell.

[0008] Preferably, the filtration mechanism includes a filter screen slidably connected in the filter tank, and the inner bottom of the filter screen is elastically connected to the inner bottom of the filter tank by a spring.

[0009] Preferably, a rotating shaft is rotatably connected between the front inner walls of the filter tank, and a cam is fixedly connected to the rotating shaft. The cam abuts against the lower end of the filter screen. A mounting bracket is installed on the front side of the housing, and a drive motor is installed on the mounting bracket. The output shaft of the drive motor extends into the filter tank and is fixedly connected to the front end of the rotating shaft.

[0010] Preferably, both the output shaft of the drive motor and the rotating tube are equipped with synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt drive.

[0011] Preferably, a rectangular strip is fixedly connected to the bottom of the processing chamber, a rectangular cavity is provided inside the rectangular strip, an air inlet strip is provided on the side wall of the rectangular cavity, and a connecting pipe is connected to the rectangular cavity.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: 1. This invention constructs a circulating drying system using components such as a circulating hot air blower, a drying chamber, and connecting pipes. This system circulates the gas within the processing chamber and dehumidifies it via silica gel drying balls, achieving continuous drying of the fabric. Simultaneously, a temperature sensor monitors the processing chamber temperature in real time. An external controller shuts off the circulating hot air blower when the temperature is too high, ensuring a suitable temperature for the circulating gas within the processing chamber. This effectively improves drying efficiency and prevents excessively high or low temperatures from affecting the fabric drying quality, guaranteeing a stable and reliable drying effect.

[0013] 2. A filter screen is installed inside the filter tank to effectively filter the fibers generated during drying, preventing them from adhering to the fabric body again and ensuring the quality of the dried fabric. The drive motor drives the rotating shaft to rotate, causing the cam and spring to make the filter screen vibrate back and forth, avoiding filter screen blockage, ensuring smooth air flow, maintaining the normal operation of the circulating drying system, reducing equipment failure and downtime caused by filter screen blockage, and improving the stability and efficiency of the equipment.

[0014] 3. The drive motor, via a synchronous pulley and belt, causes the hollow disc and the rotating shaft to rotate synchronously. Multiple air inlets intermittently connect to the connecting ports on the fixed plate as the hollow disc rotates, causing the corresponding air-blowing strips in the two horizontal cavities of the U-shaped plate to intermittently expel hot air, intermittently blowing the upper and lower sides of the fabric. Utilizing the fabric's elasticity to create vibration disrupts the surface moisture distribution, promoting the migration of internal moisture to the surface, improving the drying effect, and simultaneously ensuring more even heating of the fabric, further enhancing the drying quality.

[0015] 4. When the device requires filter cleaning, turn off the circulating hot air blower and start the external vacuum cleaner. The vacuum cleaner is connected to the rectangular cavity inside the rectangular strip via a connecting pipe. Simultaneously, start the drive motor to shake the filter, dispersing the fibers, which the vacuum cleaner can then effectively collect. This design makes filter cleaning simple and quick, eliminating the need to disassemble the filter, reducing maintenance workload and time costs, and improving the maintainability of the equipment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Reference Figures 1-6 A hot air circulation drying system for ultra-fine porous woven fabric includes a base plate 1, a shell 2 fixedly connected to the upper end of the base plate 1, a processing chamber 16 inside the shell 2, rectangular openings 14 on the inner walls of the left and right sides of the processing chamber 16, and a fabric body 3 passing through the two rectangular openings 14. Among them, two support rollers 15 are rotatably connected between the inner walls of the front and rear sides of each rectangular opening 14, and the main body of the fabric 3 is located between the two support rollers 15. It also includes a drying mechanism, which includes a U-shaped plate 17 set inside the processing chamber 16. The two horizontal parts of the U-shaped plate 17 are located on the upper and lower sides of the fabric body 3, respectively. The two horizontal parts of the U-shaped plate 17 are provided with cavities. The opposite sidewalls of the two cavities are provided with air-blowing strip-shaped openings 29. The two air-blowing strip-shaped openings 29 can intermittently blow out hot air. By utilizing the elasticity of the fabric body 3, the fabric body 3 can be shaken to improve the drying effect. The system also includes a gas circulation mechanism for achieving circulating drying. The gas circulation mechanism includes a circulating hot air blower 12 installed on the upper end of the housing 2. A temperature sensor is also installed inside the processing chamber 16. By using the temperature sensor in conjunction with the circulating hot air blower 12 and an external controller, the heating function of the circulating hot air blower 12 can be turned off when the temperature is high, so that the temperature of the circulating gas inside the processing chamber 16 can be kept at a suitable temperature. A filter groove 22 is provided at the bottom of the processing chamber 16, and the air inlet of the circulating hot air blower 12 extends into the filter groove 22. A drying box 13 is installed on the upper end of the housing 2. The drying box 13 is filled with silica gel drying balls, which can remove moisture from the circulating airflow. The blower end of the circulating hot air blower 12 is connected to the rear space of the drying box 13. The U-shaped plate 17 is fixedly connected to a fixing plate 30 on its front side. The fixing plate 30 has two connecting ports 31 that are respectively connected to the corresponding cavities. A hollow plate 28 is provided on the front side of the fixing plate 30 and fits against it. Multiple air inlets 32 are provided on the rear side of the hollow plate 28. A rotating tube 11 is connected to the front side of the hollow plate 28. The front end of the rotating tube 11 extends to the outside and is connected to a connecting tube 9 through a rotary joint 10. The other end of the connecting tube 9 is connected to the front space of the drying oven 13. An L-shaped plate 8 is installed on the front side of the shell 2 to support the connecting tube 9. After the rotating tube 11 blows out air, the air will eventually be discharged from the multiple air inlets 32. Since the multiple air inlets 32 will intermittently connect one of the two connecting ports 31 as the hollow plate 28 rotates, the two air inlets 29 can intermittently blow out hot air.

[0021] It also includes a filtration mechanism, which is used to filter the fibers produced during drying. The filtration mechanism includes a filter screen 23 that is slidably connected in the filter tank 22. The inner bottom of the filter screen 23 is elastically connected to the inner bottom of the filter tank 22 by a spring 24. During the circulation of gas, the filter screen 23 can filter out the limiting fibers to prevent them from adhering again and ensure the quality of the fabric after drying. A rotating shaft 25 is rotatably connected to the inner wall of the front side of the filter tank 22. A cam 26 is fixedly connected to the rotating shaft 25. The cam 26 abuts against the lower end of the filter screen 23. A mounting bracket 4 is installed on the front side of the housing 2. A drive motor 5 is installed on the mounting bracket 4. The output shaft of the drive motor 5 extends into the filter tank 22 and is fixedly connected to the front end of the rotating shaft 25. When the rotating shaft 25 rotates, the elasticity of the spring 24 allows the filter screen 23 to vibrate back and forth, thus making it less prone to clogging.

[0022] Both the output shaft of the drive motor 5 and the rotating tube 11 are equipped with synchronous pulleys 6, and the two synchronous pulleys 6 are connected by a synchronous belt 7.

[0023] The bottom of the processing chamber 16 is fixedly connected to a rectangular strip 18, and a rectangular cavity 20 is set inside the rectangular strip 18. An air inlet strip 21 is opened on the side wall of the rectangular cavity 20. A connecting pipe 19 is connected to the rectangular cavity 20, and the other end of the connecting pipe 19 is connected to an external vacuum cleaner. When the device needs maintenance and the filter 23 needs to be cleaned, the vacuum cleaner is started at the same time as the drive motor 5 is started. At this time, since the circulating hot air fan 12 is turned off, the shaking of the filter 23 can shake up and disperse the limit on it, so that the vacuum cleaner can collect it better.

[0024] In this invention, the ultra-fine porous woven fabric body 3 is inserted into the processing cavity 16 through the rectangular openings 14 on the inner walls of the left and right sides of the housing 2, so that the fabric body 3 is located between the two support rollers 15, thus completing the placement of the fabric body 3. The movement of the fabric body 3 is achieved through the operation of the external winding and unwinding device.

[0025] The circulating hot air blower 12 is started. The gas in the processing chamber 16 enters the air inlet of the circulating hot air blower 12 through the filter tank 22. The circulating hot air blower 12 blows the gas into the drying chamber 13. The silica gel drying balls in the drying chamber 13 remove moisture from the circulating airflow. The dried gas then enters the drying mechanism through the connecting pipe 9 and other components to achieve circulating drying. The temperature sensor in the processing chamber 16 monitors the temperature in real time. When the temperature is too high, the heating function of the circulating hot air blower 12 is turned off in conjunction with the external controller to keep the temperature of the circulating gas inside the processing chamber 16 at a suitable temperature. During the circulation of gas, the filter screen 23 in the filter tank 22 filters the fibers generated during drying, preventing the fibers from adhering to the fabric body 3 again and ensuring the quality of the fabric after drying. When the drive motor 5 starts, its output shaft drives the rotating shaft 25 to rotate. The cam 26 on the rotating shaft 25 rotates accordingly, and with the elastic action of the spring 24, the filter screen 23 vibrates back and forth to prevent clogging. At the same time, the output shaft of the drive motor 5 is connected to the synchronous pulley 6 on the rotating tube 11 through the synchronous belt 7, so that the hollow disc 28 and the rotating shaft 25 rotate synchronously. After the hollow disc 28 starts to rotate, as the multiple air inlets 32 rotate with the hollow disc 28, they intermittently open one of the two connecting ports 31 on the fixed plate 30, causing the two air inlets 29 corresponding to the two horizontal cavities of the U-shaped plate 17 to intermittently blow out hot air. The hot air intermittently blows the upper and lower sides of the fabric body 3, using the elasticity of the fabric body 3 to achieve vibration, breaking the surface moisture distribution of the fabric, promoting the migration of internal moisture to the surface, and improving the drying effect. When the device requires maintenance and the filter 23 needs cleaning, turn off the circulating hot air blower 12 and start the external vacuum cleaner, which is connected to the rectangular cavity 20 inside the rectangular strip 18 via the connecting pipe 19. At the same time, start the drive motor 5, and the filter 23 shakes to disperse the fibers, which are then collected by the vacuum cleaner.
