The two pulleys 5 are connected by belt drive. Motor 6 is located on the right front end of the housing 1. The input end of motor 6 is electrically connected to the output end of microcontroller 8. The rear end of the output shaft of motor 6 is fixedly connected to the front end of the pulley 5 on the right side, providing a basis for the rotation of the drying rollers 3. It also includes a negative pressure fan 7, which is located in the middle of the upper end of the housing 1. The input end of the negative pressure fan 7 is electrically connected to the output end of microcontroller 8, which can quickly extract humid air. It also includes a microcontroller 8, which is located on the upper right front end of the housing 1. The input end of microcontroller 8 is electrically connected to an external power source, providing control for the drying of the raw paper.

[0024] Drying device 4: It includes mounting frame 41, tension roller 42, moving component 43, and drying component 44. The mounting frame 41 is respectively set at the upper inner front and rear of the housing 1. Four tension rollers 42 are slidably connected between the two mounting frames 41. The tension rollers 42 are numbered from right to left as roller 1, roller 2, roller 3, and roller 4. The drying rollers 3 are all installed in cooperation with the vertically adjacent tension rollers 42. The moving component 43 is set inside the housing 1, and the drying component 44 is set inside the drying rollers 3. The moving component 43 includes a bidirectional lead screw 431, a bevel gear 432, a connecting rod 433, and a bevel gear. The bidirectional lead screw 431 is rotatably connected to the middle of the left and right sides of the front mounting frame 41. The outer surface of the bidirectional lead screw 431 is threaded to the front end of the longitudinally adjacent tension roller 42. The first bevel gear 432 is located on the inner end of the bidirectional lead screw 431. The connecting rod 433 is rotatably connected to the middle of the front mounting frame 41. The second bevel gear 434 is located at the lower end of the connecting rod 433. The first bevel gear 432 meshes with the second bevel gear 434, providing a basis for the bonding of the base paper. The moving component 43 also includes a first motor 435, which is located in the housing 1. At the upper front center, the input end of motor 435 is electrically connected to the output end of microcontroller 8. The lower end of the output shaft of motor 435 is fixedly connected to the upper end of connecting rod 433, providing stable drive for the bonding of the base paper. The drying assembly 44 includes air guides 441, rotary joints 442, and pressure relief valves 443. The air guides 441 are all located inside the drying roller 3 and are arranged in a cross shape, dividing the drying roller 3 into four inner cavities. The air guides 441 have evenly distributed air holes in the middle. The rotary joints 442 are all located at the rear center of the housing 1. The front side of the rotating end of 2 is fixedly connected to the rear side of the longitudinally adjacent drying roller 3. The rotating joint 442 is a gas rotating joint. The main function of the gas rotating joint is to provide a transition sealing device for the gas medium input from the static system to the dynamic rotating system, providing a basis for slowing down and uniformly distributing the steam flow rate. The tension roller 42 can be moved to make the paper fit the surface of the drying roller 3 to the maximum extent. The steam flow rate can be slowed down by the air guide frame 441 and the pressure relief valve 443, and the steam can be distributed more evenly in the drying roller 3, which improves the heat exchange efficiency of the steam and reduces the waste of heat.

[0025] The working principle of the paper drying device for paper bowl processing provided by this utility model is as follows: When drying the paper, it needs to be wound around the surface of the drying roller 3. The paper is wound from below the guide roller 2 on the right side, then around the top of roller 1, then around to the left side of the drying roller 3 on the right side, then around the top of roller 2, then around the top of roller 3, then around the surface of the drying roller 3 on the left side, then around the top of roller 4, and finally out from below the guide roller 2 on the left side, completing the paper winding process. Then, the microcontroller 8 controls the motor 435 to operate. The output shaft drives the connecting rod 433 to rotate, and the second bevel gear 434 also rotates accordingly. Because both bevel gears 432 and 434 are meshed, the two bevel gears 434 also rotate, driving the bidirectional lead screw 431 to rotate synchronously. Since the outer surface of the bidirectional lead screw 431 is threaded to the front end of the longitudinally adjacent tension roller 42, as the bidirectional lead screw 431 rotates, the two tension rollers 42 on the same side move inward synchronously, carrying the raw paper inward synchronously, so that the raw paper is in maximum contact with the surface of the drying roller 3. Then, the microcontroller 8 controls the second motor 6 to operate. The output shaft of motor 6 drives the right-side pulley 5 to rotate. Since the diameter of the left-side pulley 5 is larger than that of the right-side pulley 5, the two pulleys 5 can form a transmission effect, so the left-side pulley 5 also rotates synchronously. The two drying rollers 3 also rotate accordingly, driving the raw paper to move to the left. At the same time, the external steam generator produces steam, which enters the interior of the drying roller 3 through the rotary joint 442. When passing through the air guide frame 441, the high-temperature steam can be evenly distributed in the four inner cavities through the air holes. At this time, the high-temperature steam will not flow outward, and the heat can be transferred to the drying roller 3 to the maximum extent. The high-temperature drying roller 3 can quickly heat the raw paper to achieve the drying purpose. At the same time, the microcontroller 8 controls the operation of the negative pressure fan 7, which exhausts the hot air generated after drying. As steam continues to flow in, the air pressure inside the drying roller 3 increases. When the air pressure exceeds the critical value of the pressure relief valve 443, the spring inside the pressure relief valve 443 contracts, and the pressure relief valve 443 opens. The steam, after sufficient heat exchange, is released into the housing 1 to perform secondary drying on the raw paper. Then, it is drawn out by the negative pressure fan 7, and the dried raw paper is discharged from the guide roller 2 on the left side, completing the drying process of the raw paper.

[0026] It is worth noting that the microcontroller 8 disclosed in the above embodiments is an S7-200 microcontroller, the first motor 435 is a 1FT7036-5AK70-1FB2 motor, the second motor 6 is an SZG35F-750-120SK motor, and the negative pressure fan 7 is a GYF-1460 negative pressure fan. The microcontroller 8 controls the operation of the first motor 435, the second motor 6, and the negative pressure fan 7 using methods commonly used in the prior art.
