[0025] The cardboard to be cut can be placed on the cardboard placement mechanism 18 in the inner cavity of the cardboard humidity control box 1 by opening the movable door 2. The humidity of the inner cavity of the cardboard humidity control box 1 can be detected by the humidity detector 11. At the same time, the humidity threshold can be set by the humidity controller 12. When the inner cavity of the cardboard humidity control box 1 is relatively dry, the humidity detector 11 detects that the humidity is low and transmits the signal to the humidity controller 12 by means of a wire. The wire connected to the signal output end on the rear side of the humidity controller 12 is used to control the start of the booster water pump 14, so that the booster water pump 14 draws in the water source pre-filled in the water storage tank 15 and appropriately boosts the pressure to 5-7 MPa. The water source is then transmitted to the U-shaped tube 16 through the water pipe 141, and then sprayed into the inner cavity of the cardboard humidity control box 1 by a plurality of micro-mist nozzles 161 on the left side of the two vertical parts of the U-shaped tube 16 that penetrate the inner cavity of the ventilation and humidification box 3 for humidification treatment.

After the meter 11 detects that the humidity is qualified, the humidity controller 12 can be used to control the booster water pump 14 to stop working. When the humidity detector 11 detects that the humidity in the inner cavity of the cardboard humidity control box 1 is high, the signal can be transmitted to the humidity controller 12, and then the wire connected to the remaining signal output end on the rear side of the humidity controller 12 is used to control the air inlet fan 32 on the left side of the fixed vertical pole 31 in the inner cavity of the ventilation and humidification box 3 to start, and at the same time, the electric push rod 131 is controlled to start, driving the bottom telescopic plate 133 at the vertical position of the L-shaped bracket 132 and several sealing hanging plates 134 at the bottom of the telescopic plate 133 for sealing the ventilation holes 17 to move backward, so that the fixed vertical pole 31 blows the external air into the inner cavity of the cardboard humidity control box 1 after filtering the dust through the dust filter 33, and then blows it out through the ventilation holes 17, so that the cardboard in the inner cavity of the cardboard humidity control box 1 is in an environment with rapid air circulation, so that the humidity is quickly reduced.

[0026] like Figure 4 As shown, the inner cavity of the cardboard humidity control box 1 is provided with a cardboard placement mechanism 18, which includes a fixed plate 181, a plurality of U-shaped placement plates 182 are evenly fixedly installed on the front side of the fixed plate 181, an extension plate 183 is fixedly installed on the uppermost front side of the fixed plate 181, an electric push rod 2 184 is fixedly installed on the bottom of the extension plate 183, a suspension rod 185 is fixedly installed on the output end of the electric push rod 2 184, and a plurality of lifting plates 186 are evenly fixedly installed on the outer wall of the suspension rod 185, and the left and right sides of the lifting plates 186 are respectively overlapped with the opposite inner surfaces of the U-shaped placement plate 182, and four lifting placement plates 187 are evenly fixedly installed on the front side of the lifting plate 186, and the four lifting placement plates 187 are on the same vertical line as the front side of the U-shaped placement plate 182;

[0027] Since the cardboards are placed layer by layer on the plate composed of the U-shaped placement plate 182 and the lifting placement plate 187 on the front side of the lifting plate 186, when ventilation is carried out, the humidity controller 12 will also use the wire to start the electric push rod 2 184 at the bottom of the extension plate 183, so that the electric push rod 2 184 drives all the lifting plates 186 and the lifting placement plate 187 on the front side to rise, thereby expanding the gaps between the several cardboards, which is conducive to the rapid drying of them by the cross wind passing from left and right, thereby improving the drying speed.

[0028] like Figure 5 As shown, a limiting groove 191 is provided at the bottom of the inner wall of the cardboard humidity control box 1, and a limiting slide bar 192 is fixedly installed between the front and rear sides of the inner wall of the limiting groove 191. A slider 1814 is fixedly installed in the middle of the bottom of the fixed plate 181, and the slider 1814 is slidably connected to the limiting slide bar 192. A pull plate 1812 is fixedly installed at the lower front side of the fixed plate 181, and the pull plate 1812 is provided with a pull groove 1813 that runs through from top to bottom. Two pulley grooves 19 are provided at the bottom of the inner wall of the cardboard humidity control box 1, and the two pulley grooves 19 are respectively located on the left and right sides of the limiting groove 191. Pulleys 1811 are provided on the left and right sides of the bottom of the fixed plate 181. The two slides The wheels 1811 are respectively connected in a sliding manner to the two pulley grooves 19.

The single-chip microcomputer processes the data and sends the processed data to the LCD1602 for display and execution of the corresponding program. The air intake fan 32 is electrically connected to one of the signal output terminals, the booster water pump 14 is electrically connected to one of the signal output terminals, the electric linear actuator 131 is electrically connected to one of the signal output terminals, and the electric linear actuator 2 184 is electrically connected to one of the signal output terminals.

[0029] When the cardboard needs to be taken out and cut, the movable door 2 can be opened first, and then the pulling groove 1813 on the front side of the pulling plate 1812 can be used to pull the entire fixed plate 181, so that the fixed plate 181 can move toward the front side of the cardboard humidity control box 1 by sliding the two pulleys 1811 in the two pulley grooves 19. At the same time, when the fixed plate 181 moves, the sliding block 1814 can also slide on the outer wall of the limiting slide bar 192 in the limiting groove 191 to maintain the movement stability, and finally the entire fixed plate 181 is moved out to the front side of the cardboard humidity control box 1, making it convenient to take the cardboard.

[0030] The following is a detailed description of the working principle of the device for intelligently controlling cardboard humidity.

[0031] like Figure 1-5As shown, the cardboard to be cut can be placed on the cardboard placement mechanism 18 in the inner cavity of the cardboard humidity control box 1 by opening the movable door 2. The humidity of the inner cavity of the cardboard humidity control box 1 can be detected by the humidity detector 11, and the humidity threshold can be set by the humidity controller 12. When the inner cavity of the cardboard humidity control box 1 is relatively dry, the humidity detector 11 detects that the humidity is low and transmits the signal to the humidity controller 12 via a wire. The wire connected to the signal output terminal on the rear side of the humidity controller 12 controls the start of the booster water pump 14, so that the booster water pump 14 draws in the water source pre-filled in the water storage tank 15 and appropriately boosts the pressure to 5-7 MPa, and transmits the water to the U-shaped pipe 16 through the water pipe 141, and then passes through the water pipe 141. A plurality of micro-mist nozzles 161 on the left side of the vertical part of the two U-shaped tubes 16 that penetrate into the inner cavity of the ventilation and humidification box 3 spray mist into the inner cavity of the cardboard humidity control box 1 for humidification treatment. When the humidity detector 11 detects that the humidity is qualified, the humidity controller 12 can be used to control the booster water pump 14 to stop working. When the humidity detector 11 detects that the humidity in the inner cavity of the cardboard humidity control box 1 is high, the signal can be transmitted to the humidity controller 12, and then the wire connected to the remaining signal output end on the rear side of the humidity controller 12 can be used to control the air inlet fan 32 on the left side of the fixed vertical pole 31 in the inner cavity of the ventilation and humidification box 3 to start, and at the same time, the electric push rod 131 is controlled to start, driving the telescopic plate 133 at the bottom of the vertical part of the L-shaped bracket 132 and The sealing hanging plates 134 at the bottom of the telescopic plate 133 that seal the ventilation holes 17 move backward, so that the fixed upright pole 31 blows the external air into the inner cavity of the cardboard humidity control box 1 after filtering the dust through the dust filter 33, and then blows it out through the ventilation holes 17, so that the cardboard in the inner cavity of the cardboard humidity control box 1 is in an environment with rapid air circulation, so that the humidity is quickly reduced. At the same time, since the cardboard is placed layer by layer on the plate composed of the U-shaped placement plate 182 and the lifting placement plate 187 on the front side of the lifting plate 186, when ventilation is carried out, the humidity controller 12 will also start the electric push rod 2 184 at the bottom of the extension plate 183 using the wire, thereby using the electric push rod 2 184 to drive all the lifting plates 186 and the front side thereof. The lifting and placing plate 187 rises, thereby expanding the gaps between several cardboards, which is conducive to the rapid drying of the cardboards by the crosswind passing from left to right. When the cardboards need to be taken out and cut, the movable door 2 can be opened first, and then the pulling groove 1813 on the front side of the pulling plate 1812 can be used to pull the entire fixed plate 181, so that the fixed plate 181 can move toward the front side of the cardboard humidity control box 1 by sliding the two pulleys 1811 in the two pulley grooves 19. At the same time, when the fixed plate 181 moves, the sliding block 1814 can also slide on the outer wall of the limiting slide bar 192 in the limiting groove 191 to maintain the movement stability, and finally the entire fixed plate 181 is moved out to the front side of the cardboard humidity control box 1, making it convenient to take the cardboard.

[0032] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
