[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0024] As Figure 1 shown, a humidifying device for air filter paper includes a water tank 1. A top cover 2 is rotatably connected to a position near the upper side of the rear side of the water tank 1. A handle 3 is fixedly connected to the middle of the front side of the top cover 2. Two pressing roller mechanisms 4 distributed symmetrically left and right are rotatably connected to the middle of the upper side positions on the left and right sides of the water tank 1. Moisture absorption mechanisms 5 are rotatably connected to the left and right sides inside the top cover 2.

[0025] It should be noted that an ultrasonic atomizer is provided inside the water tank 1, which can atomize the water inside the water tank 1. The pressure roller mechanism 4 is composed of two pressure rollers arranged vertically, so that the filter paper has a high levelness and can enter the water tank 1 flatly, reducing the occurrence of filter paper wrinkles and damage.

[0026] As Figure 2 , Figure 3 shown, the moisture absorption mechanism 5 includes a first motor 51. The lower side of the first motor 51 is fixedly connected to the convex platform near the front side on the right side of the top cover 2. The output end of the first motor 51 is fixedly connected with a first transmission rod 52. The outer wall of the first transmission rod 52 is rotatably connected to the upper sides of the left and right sides inside the water tank 1 near the left and right ends. And there are four first transmission rods 52 distributed front and back on the left and right sides inside the water tank 1. The outer walls of the four first transmission rods 52 are all fixedly connected with belt pulleys 53. The inner sides of the belt pulleys 53 are meshed and connected with a conveyor belt 54. And a number of conveyor belts 54 are evenly distributed horizontally. The outer side of the conveyor belt 54 is fixedly connected with a sponge sleeve 55.

[0027] It should be noted that the first motor 51 drives the first transmission rod 52 located in the front upper side to rotate, causing the first transmission rod 52 to drive the belt pulley 53 to rotate. When the belt pulley 53 rotates, it drives the conveyor belt 54 to drive. When the conveyor belt 54 drives, it drives the sponge sleeve 55 to drive. The sponge sleeve 55 can adsorb the moisture in the water vapor.

[0028] As Figure 4 , Figure 5 shown, a second motor 57 is fixedly connected to the convex platform near the right side at the rear of the top cover 2. The output end of the second motor 57 is fixedly connected with a worm 58. Two dehumidification components 56 are rotatably connected to the front and rear sides inside the top cover 2 and are symmetrically distributed front and back. The dehumidification component 56 includes a second transmission rod 561. The outer wall of the second transmission rod 561 is rotatably connected to the lower sides of the front and rear sides inside the top cover 2 through a first rotating frame. The right end of the second transmission rod 561 is fixedly connected with a worm gear 59. The lower side of the worm gear 59 is meshed and connected with the upper side of the worm 58.

[0029] It should be noted that the second motor 57 drives the worm 58 to rotate. When the worm 58 rotates, it drives the worm gear 59 to rotate. When the worm gear 59 rotates, it drives the second transmission rod 561 to rotate. There is a self-locking effect between the worm 58 and the worm gear 59, so that the worm 58 can drive the worm gear 59 to rotate, but the worm gear 59 cannot drive the worm 58 to rotate in the reverse direction.

[0030] As Figure 4As shown in the figure, dehumidifying rollers 563 are closely attached to both sides of the inner sides of the front and rear walls of the sponge sleeve 55. The outer walls of the dehumidifying rollers 563 located on the inner side are rotatably connected to the cross beams fixed in the middle of the left and right sides of the inner side of the top cover 2 through the second rotating frame. The left and right ends of the dehumidifying rollers 563 located on the outer side are rotatably connected to support rollers 564 through connecting rods. The outer walls of the support rollers 564 are slidably connected to the sliding plates on the front and rear sides of the inner side of the top cover 2 through the third rotating frame. A plurality of evenly distributed cams 562 are fixedly connected to the outer wall of the second transmission rod 561. The outer sides of the cams 562 are lapped with the sides of the support rollers 564 away from the dehumidifying rollers 563.

[0031] It should be noted that when the second transmission rod 561 rotates, it drives the cams 562 to rotate. When the cams 562 rotate, they push the support rollers 564 to slide on the sliding plates, causing the support rollers 564 to push the outer dehumidifying rollers 563 to move, so as to adjust the distance between the two dehumidifying rollers 563, and further adjust the clamping force of the dehumidifying rollers 563 on the sponge sleeve 55. The support rollers 564 play a supporting role for the outer dehumidifying rollers 563.

[0032] As Figure 4 shown in the figure, a plurality of annularly distributed needle rollers 565 are rotatably connected to the outer walls of the support rollers 564, and a plurality of needle rollers 565 are evenly distributed horizontally. The outer sides of the needle rollers 565 are in contact with the outer sides of the cams 562.

[0033] It should be noted that the needle rollers 565 are used to reduce the friction between the cams 562 and the support rollers 564, so as to reduce the loss generated between the cams 562 and the support rollers 564.

[0034] As Figure 3 shown in the figure, the positions and shapes of the four first transmission rods 52 are in an inverted isosceles trapezoid.

[0035] It should be noted that the position and shape of the first transmission rod 52 only make the shape of the sponge sleeve 55 in an inverted isosceles trapezoid, so that the water squeezed out of the sponge sleeve 55 by the dehumidifying rollers 563 will not flow back onto the sponge sleeve 55 again.

[0036] Working principle of the utility model: First, the first motor 51 drives the first transmission rod 52 located at the front upper side to rotate, causing the first transmission rod 52 to drive the belt pulley 53 to rotate. When the belt pulley 53 rotates, it drives the conveyor belt 54 to transmit. When the conveyor belt 54 transmits, it drives the sponge sleeve 55 to transmit. The sponge sleeve 55 can adsorb the moisture in the water vapor, absorb the water vapor through the sponge sleeve 55. The first motor 51 drives the sponge sleeve 55 to rotate. Only when each part of the sponge sleeve 55 is squeezed by the dehumidifying roller 563, the water inside the sponge sleeve 55 is discharged on the front and rear sides, so that the sponge sleeve 55 can adsorb the water vapor for a long time, avoiding the formation of condensed water and improving the product qualification rate. Finally, the second motor 57 drives the worm 58 to rotate. When the worm 58 rotates, it drives the worm wheel 59 to rotate. When the worm wheel 59 rotates, it drives the second transmission rod 561 to rotate. There is a self-locking effect between the worm 58 and the worm wheel 59, so that the worm 58 can drive the worm wheel 59 to rotate, but the worm wheel 59 cannot drive the worm 58 to rotate in the reverse direction. When the second transmission rod 561 rotates, it drives the cam 562 to rotate. When the cam 562 rotates, it pushes the support roller 564 to slide on the slide plate, so that the support roller 564 pushes the outer dehumidifying roller 563 to move, so as to adjust the distance between the two dehumidifying rollers 563, and further adjust the clamping force of the dehumidifying roller 563 on the sponge sleeve 55. The support roller 564 plays a supporting role for the outer dehumidifying roller 563. By driving the first motor 51 to rotate through the second motor 57, the two dehumidifying rollers 563 approach or move away from each other to adjust the clamping force of the dehumidifying roller 563 on the sponge sleeve 55, avoiding excessive force from affecting the rotation of the sponge sleeve 55 or too small force to squeeze out the water inside the sponge sleeve 55. The adjustment is simple and the operation is convenient.
