[0008] As a preferred embodiment of this utility model, the drying box is made of heat insulation material, and multiple sets of conveying rollers are provided. There are four sets of conveying rollers and four sets of servo motors. The connection between the conveying rollers and the servo motors is a fixed connection.

[0009] As a preferred embodiment of this utility model, the air inlet pipe has a T-shaped structure design, the air inlet pipe runs through and extends into the drying chamber, the drying mechanism is provided in multiple sets, and the servo motor, power plug and controller are connected by electrical connection.

[0010] As a preferred embodiment of this utility model, the mounting frame is made of stainless steel, the connecting pipe passes through the guide groove and extends into the guide pipe, the connecting pipe has an L-shaped structure design, and the connection between the connecting pipe and the guide pipe and the guide pipe and the air inlet pipe is a fixed connection.

[0011] As a preferred embodiment of this utility model, the sealing gasket is made of silicone, and two sets of the mounting frame, the guide groove, the connecting pipe, the one-way valve and the guide fan are provided. The mounting frame extends through and to the outside of the drying chamber, and the one-way valve only allows air to flow into the guide pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, a paper rapid drying device with hot air circulation function is set up. The drying mechanism in the device is used to dry the paper. The paper is sent into the drying chamber and passes through the conveyor roller and the transmission roller in sequence. The controller starts the servo motor, which drives the conveyor roller to rotate. The rotating conveyor roller pushes the paper to the right and sends high-temperature steam into the air inlet pipe. The high-temperature steam entering the air inlet pipe will flow into the guide pipe and be sprayed out through the hot air nozzle. The sprayed high-temperature steam will flow downward and pass through the paper. The high-temperature steam passing through the paper will evaporate the moisture in the paper. The controller starts the guide fan, which draws the high-temperature steam passing through the paper into the guide groove. The steam entering the guide groove will flow upward and pass through the adsorption plate. The adsorption plate will absorb the water vapor in the steam. The dried steam will flow back into the guide pipe along the connecting pipe and be sprayed out again through the hot air nozzle along with the new high-temperature steam entering the guide pipe. The hot air can be continuously circulated in the drying chamber, which solves the problem that the existing paper drying equipment does not have a hot air circulation function, resulting in the hot air being discharged after drying the paper only once, and the hot air utilization efficiency is low.

[0026] The drying chamber 1 is made of heat insulation material. There are multiple sets of conveyor rollers 4, and four sets of conveyor rollers 3 and servo motors 5 are provided. The connection between the conveyor rollers 3 and the servo motors 5 is a fixed connection.

[0027] The air inlet duct 8 has a T-shaped structure design, and the air inlet duct 8 runs through and extends into the drying chamber 1. The drying mechanism 2 is equipped with multiple sets, and the servo motor 5, power plug 7 and controller 6 are connected by electrical connection.

[0028] In this embodiment, reference Figure 2 , Figure 3 as well as Figure 4 The drying mechanism 2 includes a hot air nozzle 201 fixedly connected to the top of the drying chamber 1, a guide pipe 202 fixedly connected to the top of the hot air nozzle 201, a guide groove 203 provided inside the drying chamber 1 on both the front and back of the conveyor roller 4, a mounting frame 204 slidably connected inside the guide groove 203, an adsorption plate 205 fixedly connected inside the mounting frame 204, a sealing gasket 206 fixedly connected to the outer wall of the mounting frame 204 near the adsorption plate 205, an electromagnet 207 fixedly connected inside the drying chamber 1 near the mounting frame 204, a connecting pipe 208 fixedly connected to the top of the guide groove 203, a one-way valve 209 fixedly connected inside the connecting pipe 208 near the guide pipe 202, and a guide fan 210 fixedly connected inside the guide groove 203 below the mounting frame 204.

[0029] The mounting frame 204 is made of stainless steel. The connecting pipe 208 passes through the guide groove 203 and extends into the guide pipe 202. The connecting pipe 208 has an L-shaped structure design. The connection between the connecting pipe 208 and the guide pipe 202, as well as between the guide pipe 202 and the air inlet pipe 8, is a fixed connection.

[0030] The sealing gasket 206 is made of silicone and can prevent hot air from flowing out of the gap. The mounting frame 204, the guide groove 203, the connecting pipe 208, the one-way valve 209 and the guide fan 210 are all provided in two sets. The mounting frame 204 runs through and extends to the outside of the drying chamber 1. The one-way valve 209 only allows air to flow into the guide pipe 202.

[0031] The adsorption plate 205 is made of activated carbon. Multiple sets of adsorption plate 205, hot air nozzle 201, electromagnet 207 and sealing gasket 206 are provided. The outer wall of the mounting frame 204 is coated with heat insulation paint. A handle is fixedly connected to the outer wall of the mounting frame 204.

[0032] The working process of this utility model is as follows: When the paper rapid drying equipment with hot air circulation function designed in this scheme is running, the paper is fed into the drying chamber 1, and the paper passes through the conveyor roller 3 and the conveyor roller 4 in sequence. The controller 6 starts the servo motor 5, which drives the conveyor roller 3 to rotate. The rotating conveyor roller 3 pushes the paper to the right, sending high-temperature steam into the air inlet pipe 8. The high-temperature steam entering the air inlet pipe 8 flows into the guide pipe 202 and is sprayed out through the hot air nozzle 201. The sprayed high-temperature steam flows downward and passes through the paper. The high-temperature steam passing through the paper evaporates the moisture in the paper. The controller 6 starts the guide fan 210, which draws the high-temperature steam passing through the paper into the guide groove 203. The steam entering the guide groove 203 rises upward. The steam flows through the adsorption plate 205, which absorbs the moisture in the steam. After drying, the steam flows back into the guide pipe 202 along the connecting pipe 208 and is then sprayed out again along the hot air nozzle 201 with the new high-temperature steam entering the guide pipe 202. The hot air can circulate continuously in the drying chamber 1. After drying is completed, the controller 6 turns off the electromagnet 207, and the electromagnet 207 no longer attracts the mounting frame 204. The mounting frame 204 is pulled and removed from the drying chamber 1. The adsorption plate 205 in the mounting frame 204 is replaced. After replacement, the mounting frame 204 is reinserted into the drying chamber 1. The controller 6 then activates the electromagnet 207, which attracts the mounting frame 204 again, fixing the mounting frame 204 in the drying chamber 1.

[0033] The controller 6, servo motor 5, power plug 7, electromagnet 207, and airflow fan 210 used in this utility model are all existing known electrical devices, and can all be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the controller 6, servo motor 5, power plug 7, electromagnet 207, and airflow fan 210 will not be described in detail here.

[0034] All standard parts used in this application can be purchased from the market.
