DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6 The present invention provides a humidifying device for processing insulating cardboard, comprising a support frame 1 and two rotating rollers 3 rotatably connected to the support frame 1. The two rotating rollers 3 are connected by a conveyor belt 12. Multiple support rollers are rotatably connected to the support frame 1 and positioned between the two rotating rollers 3, providing sufficient support for the conveyor belt 12 and ensuring more stable board transportation. The rotating rollers 3 are connected to a motor 2 for driving the rotating rollers 3. Drive wheels 11 are connected to both ends of the rotating rollers 3, each of which is connected to a centering mechanism for centering the board. A U-shaped seat 9 is connected to the center of the support frame 1, and a connecting pipe 35 is connected to the U-shaped seat 9. One end of the connecting pipe 35 is connected to a rotary joint 28, and the rotary joint 28 is connected to a rotatable sprinkler head 16. The sprinkler head 16 is connected to a swinging mechanism for driving the sprinkler head 16 to swing. The swinging mechanism includes a rotating shaft 23, a crank 24, and a connecting rod 25. Both ends of the crank 24 are connected to the rotating shaft 23 and the connecting rod 25 through an axis, and the end of the connecting rod 25 is connected to the sprinkler head 16 through an axis. The rotating roller 3 is connected to a transmission mechanism for driving the rotating shaft 23 to rotate. The other end of the connecting pipe 35 is connected to a flow regulating box 33, and the end of the rotating shaft 23 is connected to an adjusting mechanism for adjusting the flow inside the flow regulating box 33.

[0020] The plate is placed on the conveyor belt 12, and the motor 2 drives the rotating roller 3 to rotate, so that the conveyor belt 12 is transported, which facilitates the transportation of the plate from one end of the support frame 1 to the other end. The plate is sprayed and humidified by the spray head 16 in the middle, and there is no need to manually push the plate operation, saving time and effort.

[0021] The centering mechanism includes two push plates 6, two concave cams 4, two push rods 17, two convex surfaces 18, four concave surfaces 19, four guide seats 20, four springs 21, and four guide columns 22. The guide seat 20 is connected to the top of the support frame 1, the guide column 22 is slidably connected to the guide seat 20, and the end of the guide column 22 is connected to the push plate 6, the spring 21 is sleeved on the guide column 22, and the two ends of the spring 21 are connected to the guide seat 20 and the push plate 6. The concave cam 4 is rotatably connected to the support frame 1, the convex surface 18 and the concave surface 19 are arranged on one side of the concave cam 4, one end of the push rod 17 is connected to the push plate 6, and the other end is against one side of the concave cam 4, the driving wheel 11 is connected to the concave cam 4 through a belt drive, and the other end of the push rod 17 is a spherical structure. During the forward movement of the sheet, the rotation of the drive wheel 11 drives the rotation of the concave cam 4, causing the end of the push rod 17 to slide on the convex surface 18 and concave surface 19. Combined with the use of spring 1 21, the push plate 6 reciprocates, facilitating the centering of the sheet and achieving the desired position correction, facilitating subsequent spraying and humidification operations. The movement of the push plate 6 also drives the movement of the guide post 22, causing it to slide relative to the guide seat 20, effectively guiding the push plate 6 and improving the stability of its reciprocating movement.

[0022] The convex surface 18 and the concave surface 19 are smooth surfaces, and the end of the push rod 17 is a spherical structure, which can reduce contact friction.

[0023] The swing mechanism further includes a conical tooth 1 26 , which is fixed to the rotating shaft 23 and connected to the transmission mechanism.

[0024] The transmission mechanism includes a driven wheel 10, an upper wheel 13, a reducer 14, a transmission shaft 15, and a conical tooth 27. The driven wheel 10 is rotatably connected to the support frame 1, the upper wheel 13 is rotatably connected to the U-shaped seat 9, the reducer 14 is connected to the top of the U-shaped seat 9, the driven wheel 10 and the driving wheel 11 are connected by a belt drive, and the driven wheel 10 and the upper wheel 13 are connected by a belt drive. The input end of the reducer 14 is connected to the upper wheel 13, and the output end is connected to the transmission shaft 15. The conical tooth 27 is fixed to the transmission shaft 15, and the conical tooth 27 matches the conical tooth 1 26. The rotation of the drive wheel 11 synchronously drives the driven wheel 10, which in turn drives the upper wheel 13. The reducer 14 adjusts the rotation speed to keep the drive shaft 15 at an appropriate speed. The drive shaft 15 synchronously drives the rotation of the conical gear 27. The conical gear 27 cooperates with the conical gear 1 26 to rotate the rotating shaft 23. In conjunction with the crank 24 and connecting rod 25, the spray head 16 performs an arc-shaped reciprocating motion around the rotary joint 28, facilitating the spraying and humidification of both sides of the plate. At the same time, the rotation of the rotating shaft 23 also drives the rotation of the rotating disk 29. In conjunction with the oblong plate 30, the connector 31, and the lifting rod 37, the baffle 39 is raised and lowered, changing the cross-sectional size of the water channel 40. As the swing angle of the spray head 16 gradually increases, the cross-sectional size of the water channel 40 gradually increases, increasing the water flow rate within the spray head 16, ensuring a denser spray on both sides of the plate and uniform humidification of the plate. This replaces traditional manual operation and saves time and effort.

[0025] The regulating mechanism includes a rotating disk 29, an oblong plate 30, a connecting head 31, a fixed seat 32, a lifting rod 37, a second spring 38, and a baffle 39. The rotating disk 29 is connected to the end of the rotating shaft 23, the two ends of the oblong plate 30 are connected to the rotating disk 29 and the connecting head 31, the two ends of the lifting rod 37 are connected to the connecting head 31 and the baffle 39, the fixed seat 32 is connected to the top of the flow regulating box 33, the lifting rod 37 passes through the fixed seat 32, the two ends of the second spring 38 are connected to the connecting head 31 and the fixed seat 32, and the baffle 39 is sealingly slidably connected to the flow regulating box 33 to improve the sealing of the connection between the two and prevent water leakage.

[0026] A water delivery channel 40 is provided in the flow regulating box 33 , and the baffle 39 is connected to the water delivery channel 40 .

[0027] The support frame 1 is connected to a laser emitter 7 and a laser receiver 8, located opposite each other. A solenoid valve 34 is connected to the input end of a flow control box 33, which is electrically connected to the laser receiver 8 and the laser emitter 7. Solenoid valve 34 is connected to a water supply pipe 36, which is connected to a water supply unit. This unit is conventional and maintains a constant flow rate through the water supply pipe 36. Therefore, the flow rate within the sprinkler head 16 is regulated by varying the cross-sectional area of the water supply channel 40. When the sheet metal moves to a certain position, it blocks the signal from the laser emitter 7. At this point, the laser receiver 8 does not receive the signal, and the solenoid valve 34 opens, delivering water to the sprinkler head 16 for spraying and humidification. When all the sheet metal is humidified and has moved to the other end of the support frame 1, the laser receiver 8 receives the signal from the laser emitter 7, and the solenoid valve 34 closes, stopping the water supply to the sprinkler head 16, thus conserving water.

[0028] The motor 2 is fixed to the support frame 1 , and a power output end of the motor 2 is connected to the driving wheel 11 .

[0029] Working Principle: The sheet material is placed on conveyor belt 12. Motor 2 drives rotating roller 3 to rotate, causing conveyor belt 12 to operate and drive the sheet material forward. During this process, rotating roller 3 rotates the two drive wheels 11, which in turn rotate the concave cam 4, causing the end of push rod 17 to slide against the inner surface of concave cam 4. That is, push rod 17 slides relative to concave surface 19 and convex surface 18. Combined with the use of spring 1 21, push plate 6 can be moved back and forth, facilitating the correction of the sheet material's position to the middle position for subsequent spraying and humidification. When the sheet material moves forward to the appropriate position, laser receiver 8 no longer receives the signal from laser transmitter 7. At this time, solenoid valve 24 opens, and the water supply unit supplies water to the sprinkler head 16. Furthermore, the rotation of drive wheel 11 drives the rotation of driven wheel 10, which in turn drives the upper wheel 13. The speed is then adjusted by reducer 14 to ensure that the transmission shaft 15 has an appropriate rotation speed. Drive shaft 15 rotates conical gear 27, which cooperates with conical gear 1 26 to rotate shaft 23. This, combined with crank 24 and connecting rod 25, causes spray head 16 to perform an arc-shaped reciprocating motion around rotary joint 28, facilitating spraying and humidifying operations on both sides of the sheet material. Simultaneously, the rotation of shaft 23 also drives the rotation of rotating disk 29. This, combined with the oblong plate 30, connector 31, and lifting rod 37, raises and lowers baffle 39, changing the cross-sectional size of water channel 40. As the swing angle of spray head 16 gradually increases, the cross-sectional area of water channel 40 gradually increases, increasing the water flow rate within spray head 16 and ensuring dense spraying on both sides of the sheet material, resulting in uniform humidification and high processing efficiency. When the sheet material continues to move forward after humidification, laser receiver 8 receives a signal from laser transmitter 7, closing solenoid valve 34 and halting water supply to spray head 16, thereby conserving water.

[0030] The support frame 1 is connected to a controller, and the laser receiver 8 sends the received signal to the controller, and the controller controls the electromagnetic valve 24 to close. Conversely, when the laser receiver 8 does not receive a signal, the controller controls the electromagnetic valve 24 to open.
