[0021] The utility model is further described below in conjunction with the embodiments and drawings.

[0022] In the embodiment, Figure 1 , 2 As shown, a dual-channel dehumidification device for resin roller coating equipment includes: two dehumidifiers 7 and two groups of resin coating equipment; a first air path 1 and a second air path 2, connecting the first group of resin coating equipment and the first dehumidifier 7, respectively used for recovering wet air and conveying dry air; a third air path 3 and a fourth air path 4, connecting the second group of resin coating equipment and the second dehumidifier 7, respectively used for recovering wet air and conveying dry air; a fifth air path 5, serving as a connecting bypass between the first air path 1 and the second air path 2; a sixth air path 6, serving as a connecting bypass between the third air path 3 and the fourth air path 4; control valves 8 are provided on the first air path 1, the second air path 2, the third air path 3 and the fourth air path 4. This embodiment realizes the function of dual-channel dehumidification by setting two dehumidifiers 7 in parallel and dividing the resin coating equipment into two groups. When one dehumidifier 7 fails or needs maintenance, the other dehumidifier 7 can automatically take over the work, ensuring the continuous operation of the equipment and production continuity; by setting the control valve 8 to control the air path of each group of resin coating equipment, it can be controlled individually, and the flow direction and flow rate of the airflow can be flexibly adjusted, which has better applicability to different working conditions; by setting the control valve 5 and the connecting bypass, flexible switching of the air path is realized, which is convenient for operators to make adjustments and maintenance according to actual conditions.

[0023] In the embodiment, Figure 1 As shown, the resin coating equipment of the same type is classified into the same group. Specifically, the first group of resin coating equipment is the bandage coating machine 9; the second group of resin coating equipment is the splint coating machine 10. In this embodiment, the grease coating equipment is grouped according to its type. Through each control valve 5, the fifth gas path 5 and the sixth gas path 6, the dehumidification device can be flexibly adjusted according to different production tasks, and it is also convenient to adjust according to the production volume.

[0024] In the embodiment, Figure 1 As shown, the control valve 8 of the first gas circuit 1 is arranged between the fifth gas circuit 5 and the first group of resin coating equipment, the control valve 8 of the second gas circuit 2 is arranged between the fifth gas circuit 5 and the second group of resin coating equipment; the control valve 8 of the third gas circuit 3 is arranged between the sixth gas circuit 6 and the first dehumidifier 7, and the control valve 8 of the fourth gas circuit 4 is arranged between the sixth gas circuit 6 and the second dehumidifier 7. The control valves 8 of this embodiment cooperate with each other, and the flow direction and flow rate of the airflow can be flexibly adjusted manually or automatically to meet the requirements of various production situations. This arrangement of pipelines and control valves 8 also has the advantage of less interference between the various devices.

[0025] In the embodiment, Figure 2As shown, the dehumidifier 7 adopts a combined rotary dehumidifier. Specifically, the dehumidifier 7 includes: a primary filtration section 701, a pre-cooling section 702, a rotary dehumidification section 703, a return air fan section 704, a heat and moisture treatment section 705, a supply air fan section 706, a silencer section 707 and a secondary filtration section 708 in sequence along the air flow direction. Among them: the primary filter section 701 is used to filter large particles of impurities and dust in the air, protect the normal operation of the subsequent dehumidifier equipment, and extend the service life of the equipment; the pre-cooling section 702 condenses the water vapor in the air into water droplets and discharges them outside the equipment to pre-treat the air and improve the dehumidification effect; the rotary dehumidification section 703 adopts the rotary dehumidification technology to absorb the water vapor in the air through the rotating adsorbent, thereby achieving the dehumidification effect; the return fan section 704 is used to send the wet air from the resin roller coating equipment back to the dehumidifier 7; the hot and wet treatment section 705 increases the temperature of the air and helps evaporate the moisture on the adsorbent to restore its adsorption capacity; the blower section 706 sends the treated dry air out of the equipment to provide a dry working environment for the resin roller coating equipment; the silencer section 707 reduces the noise generated during the operation of the equipment through the silencer design, and improves the comfort of the working environment of the equipment; the secondary filter section 708 filters the air again before the air is supplied to remove the possible residual tiny particles and dust, ensure the air quality of the air supply, and then ensure the cleanliness of the inside of the resin roller coating equipment to maintain the product quality. This embodiment uses two combined rotary dehumidifiers, and the functional sections arranged along the air flow direction cooperate with each other to jointly complete the treatment of humidity in the air, thereby achieving an efficient dehumidification effect, improving air treatment efficiency, and providing good production conditions for the resin roller coating equipment.

[0026] In the embodiment, Figure 2 As shown, an emergency exhaust section 709 and an emergency air supply section 710 are also provided between the return air fan section 704 and the heat and moisture treatment section 705. When an abnormal situation occurs in the equipment, such as a decrease in air quality due to a failure of the dehumidifier 7 or other failures, the emergency exhaust section 709 is used to exhaust air that may be contaminated or damaged to ensure the cleanliness and safety of the operating environment; at this time, in order to maintain the stability and safety of the resin roller coating equipment, the emergency air supply section 710 is used to replenish fresh air to maintain the normal working air flow required by the equipment. The setting of these two functional sections can help the equipment respond to emergencies in a timely manner, ensure the safe and stable operation of the dehumidifier 7, and thus ensure the continuity of production.

[0027] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation methods of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
