[0002] Polyester-cotton fabric requires drying during production, after which it can be rolled up. Existing polyester-cotton fabric drying equipment typically uses built-in metal heating tubes or radiant heat exchangers to heat the fabric, utilizing thermal energy to rapidly evaporate internal moisture, which is then carried away by airflow, thus achieving the drying purpose. However, the surface temperature of the heating tubes is usually high and concentrated. During the drying process, the heat generated by the heating tubes rises to the top of the insulation box after dissipation, preventing heat circulation within the box and resulting in heat loss and waste.

[0013] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a polyester-cotton fabric drying device.

[0014] like Figures 1 to 4 As shown, this utility model discloses a polyester-cotton fabric drying device, comprising a housing, a conveying device, and a drying device. Openings are located at both ends of the housing, allowing the conveying device to pass through. The drying device is located inside the housing and dries the polyester-cotton fabric conveyed by the conveying device as it passes through the housing. A controller 16 is also located outside the housing, connected to the drying device and the conveying device for control. Specifically, the housing includes a first insulated box 1 with an open top and a second insulated box 2 with an open bottom. Support plates 3 are provided on the top surfaces of the side walls of the first insulated box 1. The second insulated box 2 is located on the top surface of the support plates 3 and is detachably connected to the support plates 3 to facilitate the installation of the conveying device and the drying device inside the first and second insulated boxes 1 and 2, and also to facilitate future maintenance of the drying device. The combination of the first insulated box 1, the second insulated box 2, and the support plates 3 forms openings at both ends of the first and second insulated plates for the conveying device to pass through. Furthermore, the interior of the first insulation board, the support plate 3, and the second insulation board is combined to form an insulation cavity.

[0015] Specifically, the second insulation box 2 and its corresponding support plate 3 are rotatably connected via a connector. That is, when the second insulation box 2 needs to be opened, pushing the side of the second insulation box 2 opposite the connector will cause the second insulation box 2 to rotate around the connector, thereby opening the second insulation box 2 and exposing the drying device inside the box, thus providing space for the drying device to be disassembled and maintained inside the box. In this embodiment, the connector is preferably a hinge. To achieve automatic opening and closing of the second insulation box 2, hydraulic cylinders 15 are rotatably installed on both ends of the first insulation box 1 on one side of the conveying device, and the extension and retraction ends of the hydraulic cylinders 15 are rotatably connected to the second insulation box 1. The hydraulic cylinders 15 are existing technology and are connected to an external power supply. The two hydraulic cylinders 15 are connected via a controller 16 so that the two hydraulic cylinders 15 extend and retract in the same direction and at the same speed.

[0016] like Figure 2As shown, the drying device includes heating tubes 17 respectively installed in the first insulation box 1 and the second insulation box 2, and the heating tubes 17 are connected to an external power supply via a controller 16. A circulating fan is also installed inside the box to evenly distribute the heat generated by the heating tubes 17, and a drive device is provided on the box to drive the circulating fan to rotate. After the drive device drives the circulating fan to work, the heat generated by the heating tubes 17 is guided towards the polyester-cotton fabric located at the center line of the circulating fan under the action of the circulating fan, and a uniform and stable hot air circulation airflow is formed within the insulation chamber. This airflow can completely wrap around the polyester-cotton fabric, ensuring that both sides are evenly heated, thus improving the drying efficiency of the polyester-cotton fabric.

[0017] Specifically, the circulating fan includes mounting rings 5 ​​mounted on the bottom surfaces of both ends of the housing via support legs 4. Each mounting ring 5 contains a rotatable bearing ring 6, and multiple fan plates 7 are distributed along their contours between the two bearing rings 6, arranged counter-clockwise. These fan plates guide heat from the heating tube 17 to the polyester-cotton fabric of the conveying device when the circulating fan rotates. A controller 16 is connected to the heating tube 17. When the fan plates 7 rotate, they create a continuous and uniformly oriented airflow field. This airflow agitates and guides the heat generated by the heating tube 17 to the polyester-cotton fabric at the center of the airflow field, improving the utilization rate of all heat inside the housing and reducing heat waste. This solves problems such as uneven heating, localized dampness, or over-drying caused by stagnant or unidirectional hot air blowing, significantly improving the quality of the finished fabric.

[0018] The driving device includes a first motor 8 mounted on the first insulation box 1 and connected to the controller 16, which rotates a connecting shaft mounted on the side wall of the first insulation box 1. A gear 9 is mounted on the connecting shaft, and an internal gear ring 10 is mounted inside the bearing ring 6 on the side corresponding to the first motor 8. The gear 9 meshes with the internal gear ring 10.

[0019] like Figure 1 As shown, the conveying device for transporting polyester-cotton fabric includes two parallel supports 11 connected at both ends by rollers 12, with a conveyor belt for holding the polyester-cotton fabric wound between the two rollers 12. Simultaneously, a second motor 14 connected to an external power source is also provided at one end of one of the supports 11, and the second motor 14 is rotatably connected to its corresponding roller 12. When the second motor 14 drives the connected roller 12 to rotate, the two rollers 12 will rotate at the same speed and in the same direction under the action of the conveyor belt. The polyester-cotton fabric to be dried is then placed on the conveyor belt, and the movement of the conveyor belt transports the fabric. When the polyester-cotton fabric passes through the drying device, the drying device dries the fabric. To monitor the temperature inside the chamber in real time, a temperature sensor is installed inside the chamber, and the controller 16 is connected to the second motor 14 and the temperature sensor.

[0020] In use, the controller 16 starts the first motor 8. The first motor 8 begins to rotate, driving the connecting shaft connected to it to rotate. The gear 9 fixed to the end of the connecting shaft rotates synchronously. The rotation of the gear 9 drives the internal gear ring 10, which in turn drives the bearing ring 6 to rotate. The multiple fan plates 7 fixed between the two bearing rings 6 rotate synchronously. The rotation of the fan plates 7 creates a circulating airflow within the insulation cavity. During the flow of the circulating airflow, it continuously passes through the heating tubes 17 on both the upper and lower sides, and is fully and evenly heated. This heated and uniform airflow is forced onto the polyester-cotton fabric located at the center of the airflow field, providing all-round, dead-zone-free enveloping heating to its upper and lower surfaces, causing moisture to evaporate rapidly.

[0021] To prevent damage to the conveyor belt, in this embodiment, the conveyor belt used to connect the two rollers 12 is made of high-temperature resistant rubber, and the conveyor belt has evenly distributed through holes. The through holes allow heat to be applied to the bottom surface of the polyester-cotton fabric attached to the conveyor belt during the drying process, resulting in higher drying efficiency.

[0022] like Figure 1 and Figure 4 As shown, both ends of the conveyor device are equipped with pressing components. When the polyester-cotton fabric is conveyed on the conveyor belt, it needs to pass through the conveyor belt and pressing components at the inlet end of the conveyor device and exit through the conveyor belt and pressing components at the outlet end of the conveyor device. This ensures that the polyester-cotton fabric remains flat during the drying process and prevents wrinkles from forming when the fabric is rolled up after drying. Specifically, the pressing components include fixed blocks 18 on the top surfaces of the two supports 11, and each fixed block 18 has a cross groove 19. Sliding blocks 20 are slidably installed within the cross grooves 19, and a pressure roller 23 that contacts the conveyor belt is rotatably connected between the two sliding blocks 20 via a rotating shaft 22. A spring 21 is located between the sliding blocks 20 and the top surface of the cross groove 19. When the polyester-cotton fabric passes between the conveyor belt and the pressure roller 23, the pressure roller 23 can be lifted upwards. During the lifting process of the pressure roller 23, the rotating shaft 22 of the pressure roller 23 will drive the connected sliding blocks 20 to move upwards and compress the corresponding springs 21. After the pressure roller 23 is raised, a gap is created between the pressure roller 23 and the conveyor belt, through which the polyester-cotton fabric can pass. Once the fabric has passed through, the pressure roller 23 is released, and the spring 21 pushes the slider 20 and the rotating shaft 22 on the slider 20 to descend. The rotating shaft 22 also drives the pressure roller 23 to descend, causing the pressure roller 23 to work with the conveyor belt to press the polyester-cotton fabric firmly. When the conveyor belt rotates, it connects to the pressure roller 23 through the polyester-cotton fabric, causing the pressure roller 23 to rotate accordingly.

[0023] like Figure 4As shown, the cross groove 19 on the fixing block 18 passes through the top of the fixing block 18 to facilitate the installation of the slider 20 and the spring 21. After the slider 20 and the spring 21 are installed, a cover plate is also connected to the top surface of the fixing block 18 by bolts. The cover plate can be connected to the top surface of the fixing block 18.

[0024] Instructions for use: Introduce the polyester-cotton fabric to be dried into the inlet of the conveyor device, allowing it to pass through the gap between the pressure roller 23 of the inlet-end pressing assembly and the conveyor belt. Similarly, the end of the polyester-cotton fabric exits through the gap between the pressure roller 23 and the conveyor belt at the outlet of the conveyor device. Start the device via controller 16. Controller 16 first controls the heating tube 17 of the drying device to start working, generating heat. Simultaneously, it starts the first motor 8, which drives the internal gear ring 10 within the bearing ring 6 via the connecting shaft and gear 9, causing the two bearing rings 6 to rotate synchronously, thereby driving multiple fan plates 7 to rotate together. The rotating fan plates 7 form a circulating airflow within the insulation cavity of the chamber. This airflow continuously passes through the vertically arranged heating tubes 17 during its flow, being uniformly and fully heated to form a stable and uniform hot airflow. Controller 16 simultaneously starts the second motor 14 of the conveyor device, which drives the rotating roller 12 to rotate, thereby driving the conveyor belt and the polyester-cotton fabric on it through the chamber. Once the polyester-cotton fabric enters the insulation cavity of the chamber, it is completely enveloped by the uniform hot air generated by the fan plates 7. The hot air simultaneously heats the upper and lower surfaces of the polyester-cotton fabric efficiently and without dead zones, causing the moisture to evaporate quickly.
