Description

Technical Field

[0001] This utility model belongs to the field of toilet paper drying technology, and in particular relates to a drying device for the clean production of sterile toilet paper. Background Technology

[0002] Toilet paper is primarily used for daily hygiene and is an indispensable type of paper for the general public. To make toilet paper soft, mechanical methods are usually used to create wrinkles in the paper, increasing its softness. Many raw materials are used to manufacture toilet paper, commonly including natural and pollution-free materials such as cotton pulp, wood pulp, bamboo pulp, and straw pulp.

[0003] The production process of toilet paper involves evenly spreading the prepared pulp onto a filter screen, washing it with water, and compacting it to gradually form the shape of paper. The compacted pulp then enters a press, where it undergoes pressing and water absorption to remove as much moisture as possible, forming wet paper. The wet paper is then conveyed to a drying chamber, where temperature and humidity are controlled to gradually evaporate the moisture, ultimately achieving a dry state.

[0004] Existing technologies often require increasing the drying temperature of toilet paper to improve drying efficiency. However, prolonged exposure to high temperatures causes water vapor to accumulate in the drying chamber, reducing the drying effect. Additionally, some drying chambers use exhaust fans to remove water vapor, but this also carries away some heat, further reducing the drying effect. Therefore, a sterile toilet paper cleaning production drying device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a drying device for the production of sterile toilet paper, thereby solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a drying device for sterile toilet paper cleaning production, comprising a base, two sets of support plates symmetrically arranged on the upper surface of the base, a conveyor belt between the two sets of support plates, a drying chamber on the upper surface of the two sets of support plates, a support seat on the upper surface of the drying chamber, a drying box on the upper surface of the support seat, symmetrically arranged sliding grooves on opposite surfaces inside the drying box, a moisture-absorbing box slidably connected in the sliding grooves, a connecting pipe connected to one side of the drying box, an exhaust fan at the other end of the connecting pipe, an air guide pipe connected to the output end of the exhaust fan, an exhaust pipe connected to one side of the drying chamber, a blower at the other end of the exhaust pipe, and a moisture-absorbing pipe connected to the upper surface of the drying chamber.

[0008] The upper surface of the two sets of support plates is provided with two sets of vertical plates, the upper surface of the two sets of vertical plates is provided with a top plate, and the bottom surface of the top plate is symmetrically provided with two sets of elastic elements.

[0009] The two sets of elastic elements include hollow tubes, with sleeves slidably connected inside the hollow tubes. Springs are installed inside the hollow tubes and sleeves. A clamping plate is installed on the bottom end face of the sleeve. The clamping plate has a "U"-shaped plate structure, and a roller is rotatably connected inside the clamping plate.

[0010] One end of the spring is fixedly connected to the upper surface inside the hollow tube, the free end of the spring is fixedly connected to the bottom surface inside the sleeve, the upper surface of the hollow tube is fixedly connected to the bottom surface of the top plate, and the peripheral side of the roller is in contact with the surface of the conveyor belt.

[0011] The other end of the moisture-absorbing tube passes through one side of the drying box and is fixedly connected to one side of the drying box. The other end of the moisture-absorbing tube is connected to the drying box. The other end of the air guide tube is connected to the circumferential side of the exhaust pipe. The other end of the air guide tube is connected to the exhaust pipe.

[0012] Multiple sets of electric heating tubes are installed on the upper surface of the drying chamber. A controller is installed on one side of the drying chamber, and a temperature sensor is installed on one side of the drying chamber. The detection end of the temperature sensor passes through one side of the drying chamber and extends into the interior.

[0013] This utility model has the following beneficial effects:

[0014] This invention involves placing wet paper on a conveyor belt for transport to a drying chamber, where it is dried by an electric heating element. During the drying process, the moisture evaporated from the wet paper accumulates in the drying chamber. At this point, an exhaust fan is activated to extract the moisture through a moisture-absorbing pipe. The moisture enters the drying chamber through the moisture-absorbing pipe and then passes through the through holes on both sides of the moisture-absorbing box. The drying balls inside the moisture-absorbing box absorb the moisture, and the dried air is blown into the drying chamber by a blower through an air duct to achieve heat circulation.

[0015] Meanwhile, the temperature sensor detects the temperature inside the drying chamber and transmits the detected signal to the controller. When the temperature is higher than the maximum preset temperature in the controller, the controller controls the electric heating element to reduce its power. When the temperature is lower than the minimum preset temperature in the controller, the controller controls the electric heating element to increase its power.

[0016] After the wet paper is dried, it is conveyed out from the other end of the drying chamber. Then, the rollers flatten the heated paper. The rollers continuously apply downward pressure through the elastic elements. The rollers' peripheral side is in contact with the surface of the conveyor belt, which drives the rollers to rotate and squeeze the paper, reducing the degree of wrinkles after the paper is dried.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Two sets of elastic elements 51 are symmetrically provided on the bottom surface of the top plate 54.

[0030] Furthermore, the two sets of elastic elements 51 include a hollow tube 510, a sleeve 511 slidably connected inside the hollow tube 510, a spring 512 provided inside the hollow tube 510 and the sleeve 511, a clamping plate 52 provided on the bottom end face of the sleeve 511, the clamping plate 52 is a "U" shaped plate structure, and a roller 53 is rotatably connected inside the clamping plate 52.

[0035] Furthermore, the moisture absorption box 43 has multiple sets of through holes on its two opposing surfaces, and a drying ball is provided inside the moisture absorption box 43. The diameter of the multiple sets of through holes is smaller than that of the drying ball.

[0036] It should be noted that by placing the wet paper on the conveyor belt 2 for conveying, the wet paper is transported to the drying chamber 3 and dried by heating with the electric heating tube 33.

[0037] Meanwhile, the detection end of the temperature sensor 32 will detect the temperature inside the drying chamber 3. The temperature sensor 32 will transmit the detected signal to the controller 31. When the temperature is higher than the preset maximum temperature in the controller 31, the controller 31 will control the electric heating tube 33 to reduce the power. When the temperature is lower than the preset minimum temperature in the controller 31, the controller 31 will control the electric heating tube 33 to increase the power.

[0038] After the wet paper is dried, it is conveyed out from the other end of the drying chamber 3. Then, the roller 53 flattens the heated paper. The roller 53 continuously applies downward pressure through the elastic element 51. The side of the roller 53 is in contact with the surface of the conveyor belt 2, which can drive the roller 53 to rotate and squeeze the paper to reduce the degree of wrinkles after the paper is dried.

[0039] The controller 31 employs PID control, a more advanced control method. It combines the advantages of proportional, integral, and derivative control, and adjusts and optimizes it according to actual needs. By integrating proportional, integral, and derivative control, the PID control system can respond more quickly to temperature changes, automatically correct deviations, and provide better steady-state performance.
