A horizontal column 18 is fixedly provided between the lower ends of the vertical plates 602. A support column is fixedly provided at the center of the upper end of the horizontal column 18. A buckle plate is provided on the opposite side of the vertical plate 602 at the upper end of the horizontal column 18. A baffle 5 is fixedly provided at the center of one side of the base 1. A door 4 is provided on both sides of the baffle 5 through a movable structure. A central shaft is fixedly provided at the center of the upper end of the turntable 14. The upper end of the central shaft is rotatably connected to the corresponding top plate 201. A motor 13 is fixedly provided at the position of the central shaft on the upper end of the top plate 201. The output end of the motor 13 passes through the top plate 201 and is fixedly connected to the corresponding central shaft. An end plate 9 is fixedly provided between the side plate 2 and the side of the side plate 2 away from the baffle 5.

[0044] Through the above configuration, the side plate 2, top plate 201, baffle 5, and baffle door 4 of this utility model form a certain sealing surface, which can effectively allow hot air to quickly converge and improve drying efficiency. The hot air structure of this utility model can heat the air to dry the plastic woven bags. The conveyor belt 15, buckle plate, and support column of this utility model allow the plastic woven bags to be inverted on the support column, and the handles on both sides can be locked on the buckle plate, so that the plastic woven bags can be fixed in reverse. The opening of the plastic woven bags is open during transportation, and the water stains inside the plastic woven bags can be quickly discharged. The hot air can effectively contact the inside and outside of the plastic woven bags to achieve rapid and complete drying with short drying time and high drying efficiency. The motor 13 of this utility model drives the central shaft to rotate, which in turn drives the turntable 14 to rotate and realizes the movement of the conveyor belt 15. The end plate 9 of this utility model can further seal the drying area and effectively prevent internal heat loss.

[0045] like Figures 2 to 6 As shown, the baffle 5 is located inside the end of one end of the conveyor belt 15. Both ends of the baffle 5 are fixedly provided with sealing strip 501. The side of the gate 4 near the baffle 5 is fixedly provided with sealing strip 402. The side plate 2 is provided with a through groove 202 on the side corresponding to the gate 4. The side of the gate 4 away from the baffle 5 is locked in the through groove 202. The lower end of the side of the gate 4 near the baffle 5 is fixedly provided with adjusting block 401. The upper end of the base 1 is provided with an embedded groove 102 corresponding to the position of the adjusting block 401. The adjusting block 401 is locked in the embedded groove 102. The center of the adjusting block 401 is provided with a threaded post 301 through a threaded connection. The two ends of the threaded post 301 are rotatably connected to the two ends of the corresponding embedded groove 102 respectively. The two sides of the base 1 are fixedly provided with motor 3 corresponding to the position of the threaded post 301. The output end of the motor 3 passes through the base 1 and is fixedly connected to one end of the corresponding threaded post 301.

[0046] Through the above settings, the sealing strip 501 and sealing strip 402 of this utility model enable the baffle 4 and baffle 5 to be effectively sealed, further preventing internal heat loss. The motor 3, threaded column 301 and adjusting block 401 of this utility model enable the threaded column 301 to rotate when a plastic woven bag is fixed on the outer support column, and thus the adjusting block 401 to move when the motor 3 is started, thereby opening the baffle 4. At this time, the motor 13 is started, and the plastic woven bag on the outer side can be moved to the inner side for drying. The support column on the other side without a plastic woven bag will be transported to the outer side, and then the baffle 4 will be closed. This reduces heat loss when fixing or removing the plastic woven bag.

[0047] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the support column includes a base column 20, with several extension columns 17 at its upper end. Both the base column 20 and the extension columns 17 have externally threaded portions 19 fixedly at their upper ends. The lower ends of the extension columns 17 have internally threaded grooves 21, and the externally threaded portions 19 are threadedly connected to the corresponding internally threaded grooves 21. The buckle plate includes a fixing portion 8, which is fixedly connected to the corresponding upright plate 602. A semi-circular portion 801 is fixedly fixedly at the lower end of the fixing portion 8, and a stop block 802 is fixedly fixedly at the lower end of the semi-circular portion 801. An inclined portion 803 is provided at the lower end of the stop block 802, and one side of the stop block 802 is connected to... The corresponding upright plate 602 abuts against each other, and the lower end of the inclined part 803 extends away from the upright plate 602; the hot air structure also includes a blower 11 and a heater 12. The blower 11 and the heater 12 are respectively fixedly connected to the upper end face of the top plate 201. An air inlet pipe 10 is fixedly provided on one side of the blower 11. The side of the air inlet pipe 10 away from the blower 11 passes through the corresponding top plate 201. The air outlet of the blower 11 is connected to the air inlet of the heater 12. The air outlet of the heater 12 is connected to the air outlet pipe 7; a sealing plate 16 is fixedly provided at the lower end of the top plate 201 above the baffle 4.

[0048] Through the above configuration, the extension column 17, the external threaded portion 19, and the internal threaded groove 21 of this utility model allow the extension column 17 to be adjusted in length according to the length of the plastic woven bag, thus facilitating its support. The semi-ring portion 801, the stop block 802, and the inclined portion 803 of this utility model allow the handle to be placed on the inclined portion 803 and pulled upwards, thereby opening the stop block 802 and securing the handle within the semi-ring portion 801 to fix the plastic woven bag, preventing it from detaching from the conveyor belt 15 during the drying process. The fan 11 and the heater 12 of this utility model allow the fan 11 to draw in air from the inside through the air inlet pipe 10, heat it through the heater 12, and then allow it to enter the single air pipe 701 through the air outlet pipe 7 to dry the plastic woven bag. The sealing plate 16 of this utility model further seals the drying area, effectively preventing heat loss from the inside.

[0049] Working principle: During use, the induced draft fan 11 and heater 12 can be started. The induced draft fan 11 draws in the air from the inside, heats it through the heater 12, and then enters the inside through the outlet pipe 7 and single air pipes 701. The hot air will converge on the inside of the top plate 201 and the side plate 2. Then, the plastic woven bag is placed on the support column outside the gate 4, and the handles on both sides of the plastic woven bag are locked in the semi-ring 801. After the bag is placed, motor 13 and motor 23 are started simultaneously. Motor 23 drives the threaded column 301 to rotate, thereby opening the gate 4. Motor 13 drives the turntable 14 to rotate, thereby moving the conveyor belt 15, so that the plastic woven bag that has been placed is moved to the inside of the gate 4. The support column will move to the outside, at which point motor 13 stops starting, and motor 2 drives the stop gate 4 back to its original position. This process is repeated until all the plastic woven bags are fitted onto the support column. The plastic woven bags move inside to achieve effective drying on both the inside and outside. After one round of transportation of the plastic woven bags, the dried plastic woven bags can be removed, and the plastic woven bags that need to be dried can be fitted onto them again. The length of the support column can be changed by installing different numbers of extension columns 17 according to the required length of the plastic woven bags. The starting and stopping of motor 13, motor 23, fan 11, and heater 12, as well as their operating principles, electrical connection lines, and connection methods with the control panel, are all disclosed in the prior art. Therefore, this application will not elaborate further.
