In this utility model, the paper is first pre-wound on the surface of multiple conveying rollers, input from one material port and output from another material port, and when drying, the motor is started to drive the threaded rod to rotate, at which time the threaded rod will drive the slider 2 to move up and down, and then the inner air delivery frame moves up and down inside the drying box, so that the position of the inner air delivery frame is adjusted up and down, and at this time warm air will be input into the inner air delivery frame through the air duct, and then output from the bottom of the inner air delivery frame, and the paper rolled on the surface of the conveying roller is dried, thereby achieving the effect of uniformly drying the paper.

[0004] This patent can adjust the position of the inner air conveying frame up and down and dry the paper evenly. However, in actual use, there is a shaking problem when using a set of threaded rods to simultaneously drive two sets of sliders to adjust the inner air conveying frame up and down. The stability of the inner air conveying frame needs to be improved. Therefore, we proposed a new type of formaldehyde-free impregnated paper drying equipment. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a formaldehyde-free impregnated paper drying device, including a drying box 1, and lifting components 2 are arranged on both sides of the drying box 1. The lifting component 2 includes a motor 201 and a first pulley 202. The motor 201 is arranged at the upper end of one side of the drying box 1, and the output end of the motor 201 is connected to the first pulley 202. A transmission belt 203 is installed on the surface of the first pulley 202. A second pulley 204 is arranged on one side of the transmission belt 203. The bottoms of the first pulley 202 and the second pulley 204 are both connected to threaded rods 205, and the bottoms of the two groups of threaded rods 205 are both provided with bearings 206. The two groups of bearings 20 6 are provided with a fixed block 207 at the bottom, and a slider 208 is provided on the surface of the two groups of threaded rods 205. An inner air delivery frame 3 is provided between the two groups of sliders 208. The motor 201 is electrically connected to the external power supply through the control switch. The output end of the motor 201 is fixedly connected to the first pulley 202. The first pulley 202 is connected to the second pulley 204 through the transmission belt 203. The threaded rod 205 and the slider 208 are threadedly connected. The threaded rod 205 is rotatably connected to the fixed block 207 through the bearing 206. The two groups of sliders 208 are fixedly connected to the inner air delivery frame 3.

[0025] The effect achieved by the entire embodiment 1 is that when it is necessary to dry the paper, the paper can be first wound around the surfaces of multiple rollers, and then the motor 201 can be started by the control switch. After the motor 201 is started, the first pulley 202 can be driven to rotate through the output end of the motor 201, and while the first pulley 202 is rotating, the second pulley 204 can be driven to rotate through the transmission belt 203. When the first pulley 202 and the second pulley 204 rotate at the same time, the two groups of threaded rods 205 are also driven to rotate at the same time, and the two groups of bearings 206 can make the rotation of the two groups of threaded rods 205 more stable. When the two groups of threaded rods 205 rotate, the two groups of sliders 208 will also be threadedly rotated with the two groups of threaded rods 205, thereby driving the inner air delivery frame 3 to move up and down. The two groups of sliders 208 simultaneously drive the inner air delivery frame 3 to move up and down through the threaded rods 205, which can make the inner air delivery frame 3 more stable.

[0026] Embodiment 2, as Figure 1-Figure 5 As shown, an air duct 4 is provided on the front surface of the inner air delivery frame 3, and a filter assembly 5 is provided inside the air duct 4. The filter assembly 5 includes a mounting groove 501 and a filter screen 502. The mounting groove 501 is provided on one side surface of the air duct 4, and a filter screen 502 is slidably installed inside the mounting groove 501. A handle 503 is installed at the top center position of the filter screen 502, and a socket 504 is provided on the front surface of the filter screen 502. A slot 505 is provided inside one side of the air duct 4 close to the mounting groove 501, and a spring 506 is installed inside the slot 505. A push plate 507 is connected to one side of the spring 506, and a push rod 508 is fixedly connected to one side of the push plate 507. The push plate 507 forms an elastic structure with the spring 506 through the slot 505, and the position and size of the push rod 508 match the position and size of the socket 504.

[0027] The effect achieved by the entire embodiment 2 is that when drying paper, hot air will be blown into the inner air delivery frame 3 through the air duct 4 to dry the paper, and the filter 502 can filter dust and impurities in the air. When the filter 502 needs to be disassembled and cleaned after long-term use, the push plate 507 can be pushed backward, thereby driving the push plate 507 to squeeze the spring 506 through the notch 505, and allowing the push rod 508 to be pulled out of the socket 504. At this time, the handle 503 is grasped to remove the filter. 502 can be directly pulled out from the installation slot 501 to complete the disassembly. After the filter 502 is cleaned, when the filter 502 needs to be installed, the push plate 507 can be pulled back again, and the spring 506 can be squeezed through the slot 505 again, and the push rod 508 will also shrink toward the slot 505. At this time, the filter 502 can be slid and installed into the installation slot 501. In this way, the installation and disassembly of the filter 502 is completed, and the problem of dust being blown to the paper through the hot air and affecting the cleanliness of the paper is avoided.

[0028] Working principle: when it is necessary to adjust the inner air delivery frame 3 up and down and dry the paper, the motor 201 can be turned on to drive the first pulley 202 to rotate, and the first pulley 202 will also drive the second pulley 204 to rotate through the transmission belt 203. When the first pulley 202 and the second pulley 204 rotate at the same time, the two sets of threaded rods 205 will also rotate, thereby driving the two sets of sliders 208 to drive the inner air delivery frame 3 to move up and down, avoiding the problem of shaking during operation of the inner air delivery frame 3 due to the traditional adjustment method, thereby improving the stability of the inner air delivery frame 3 during operation. When the air duct 4 is opened to transport hot air to the inner air delivery frame 3, the dust and impurities in the hot air can be filtered through the filter 502. After long-term use, when the filter 502 needs to be disassembled and cleaned, the filter 502 can also be taken out and cleaned by pulling the push plate 507, thereby avoiding the problem that the hot air is not filtered and dust and impurities in the air may be blown to the paper, resulting in poor paper cleanliness.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
