Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating and drying equipment technology, and in particular to a coating and drying mechanism. Background Technology
[0002] Coating technology is a papermaking process that uses an adhesive to brush a cementitious material onto the paper surface to improve its properties. Based on the processing method, coating technology can be divided into two main categories: dry coating and wet coating. The coating materials used include various adhesives, water-soluble paints, inks, etc., which quickly form a stable film on the substrate surface after coating.
[0003] During production, drying equipment is used to accelerate the curing of the substrate. For example, Chinese utility model patent CN221387306U discloses a coating drying device with a liftable air nozzle. This device uses an angle adjustment mechanism and a height adjustment mechanism installed on the coating machine as a mounting platform for the air nozzle assembly. This allows for multi-directional adjustment of the height and air outlet direction of the air nozzle assembly according to different types of substrates and coating materials passing through the coating machine, making it more flexible to use and thus ensuring the drying effect.
[0004] However, in actual operation, the nozzles of the aforementioned coating drying device are narrow at the top and wide at the bottom. According to the basic principles of fluid dynamics, air flows from the narrowest point to the widest point, and the flow velocity will decrease. Therefore, the air blown out of the nozzle will have a more severe velocity reduction as it moves outward, resulting in a poor drying effect on the substrate coating. Under the same operating standards, the energy consumption is high, thus failing to guarantee economic efficiency. Utility Model Content

[0027] In an exemplary embodiment, as Figures 1-8 shown, this embodiment provides a coating drying mechanism, including a frame body 100, an air chamber 200, an air drying member 300, a driving member 400 and a guiding member 500. The air chamber 200 includes an upper chamber 210 and a lower chamber 220 which are arranged oppositely. Pump bodies 230 are provided at the top of the upper chamber 210 and the bottom of the lower chamber 220 respectively. There are two groups of air drying members 300, and the two groups of air drying members 300 are respectively arranged at the bottom of the upper chamber 210 and the top of the lower chamber 220 and are used for air cooling the surface of the substrate. The driving member 400 is arranged on the air chamber 200 and is used for driving the air drying member 300 to rotate. The guiding member 500 is sleeved outside the air drying member 300 and is used for guiding the air flow direction.
[0028] In the above embodiment, the substrate is passed between the upper chamber 210 and the lower chamber 220. The pump body 230 is started to pump sufficient air into the air chamber 200. At the same time, the driving member 400 is started, and the driving member 500 drives the air drying member 300 to blow air on the surface of the substrate. At the same time, under the narrowing and guiding of the guiding member 500 to the air duct, the air flow contacts the surface of the substrate orderly, effectively reducing attenuation. By adopting the method of narrowing the air duct of the air flow by the guiding member 500 and guiding the air flow blown out by the air drying member 300, the drying effect is ensured and the operation economy is improved.
[0029] In one of the embodiments, please refer to Figures 1-3 and Figure 4 , the upper chamber 210 is in an N shape, the lower chamber 220 is in a U shape, and a plurality of strip-shaped through holes 240 are opened at the inner bottom of the upper chamber 210 and the inner top of the lower chamber 220.
[0030] In this embodiment, the strip-shaped through holes 240 are sequentially opened along the length direction of the chamber. The upper chamber 210 and the lower chamber 220 are relatively matched to form a "hui" character shape, and the cavity formed therebetween serves as a material feeding channel.
[0031] Furthermore, a plurality of material feeding rollers 260 are arranged between the inner concave side walls of the lower chamber 220 (the material feeding roller 260 is a prior art and is not specifically described, see Figure 3 The feeding roller 260 is used for feeding materials.
[0032] In one embodiment, please refer to Figures 1-8 Both sets of drying components 300 include several rotating shafts 310 respectively rotatably disposed in the upper chamber 210 and the lower chamber 220, and impellers 320 fixedly sleeved on the outside of the rotating shafts 310. Several rotating shafts 310 are respectively disposed at the top of several strip-shaped through holes 240. The lower half of the impeller 320 extends to the outside of the strip-shaped through holes 240. The rotating shafts 310 are connected to the driving component 400.
[0033] In this embodiment, the rotation of the impeller 320 can exhaust the air in the air chamber 200 to the area between the upper chamber 210 and the lower chamber 220.
[0034] Furthermore, both sides of the impeller 320 are provided with wrapping plates 330. The bottom of the wrapping plates 330 is fixedly connected to the side walls of the corresponding strip-shaped through holes 240. The length of the wrapping plates 330 is the same as that of the impeller 320. The interior of the wrapping plates 330 is provided with a sliding groove 331, and the guide member 500 is provided in the sliding groove 331.
[0035] In this embodiment, the wrapping plates 330 on both sides of the impeller 320 separate the several impellers 320, so that each impeller 320 does not interfere with each other, thereby improving the exhaust efficiency.
[0036] In one embodiment, please refer to Figure 1 and Figure 2 The drive unit 400 includes two motors 410 respectively installed outside the upper chamber 210 and the lower chamber 220. The output shafts of the two motors 410 are fixedly connected to one end of the rotating shaft 310. The two ends of several rotating shafts 310 extend through to the outside of the upper chamber 210 and the lower chamber 220 respectively. Sprockets 420 are fixedly provided at both ends of several rotating shafts 310. The same chain link 430 is sleeved on the outside of two adjacent sprockets 420.
[0037] In this embodiment, two motors 410 drive corresponding rotating shafts 310 respectively. The ends of two adjacent rotating shafts 310 are connected by sprockets 420 and chain links 430. The sprockets 420 and chain links 430 on different ends are distributed at intervals to realize the transmission of several rotating shafts 310.
[0038] In one embodiment, please refer to Figures 4-6 and Figure 8 The guide member 500 includes an acceleration guide plate 510 slidably disposed in the slide groove 331 and a plurality of guide pieces 520 fixedly disposed inside the acceleration guide plate 510.
[0039] In this embodiment, the side cross-section of the acceleration guide plate 510 is funnel-shaped. Specifically, the acceleration guide plate 510 gradually narrows. This structure allows the airflow to have a higher flow rate when it is discharged. In conjunction with the guide plate 520, the airflow can contact the substrate surface more stably.
[0040] In one embodiment, please refer to Figure 3 The lower chamber 220 is fitted on both sides of the top of the upper chamber 210. Several slots 211 are opened on the end side of the upper chamber 210. The end side of the lower chamber 220 is threaded with fixing pins 221, which are adapted to the slots 211.
[0041] In this embodiment, the upper chamber 210 and the lower chamber 220 can be fitted together and close to each other, and their relative positions can be fixed by fixing pins 221.
[0042] Furthermore, heating wires 250 are provided inside both the upper chamber 210 and the lower chamber 220. The heating wires 250 can make the exhaust airflow have a certain temperature, thereby further improving the drying effect.
[0043] To better understand this utility model, the following is combined with... Figures 1 to 8 The technical solution of this utility model is described in detail as follows: In use, the substrate passes between the upper chamber 210 and the lower chamber 220. The pump body 230 is started to pump sufficient air into the air chamber 200. At the same time, the motor 410 is started. The two motors 410 drive the corresponding rotating shafts 310 respectively. The ends of two adjacent rotating shafts 310 are connected by a sprocket 420 and a chain link 430. The sprockets 420 and chain links 430 on different ends are distributed at intervals to realize the transmission of several rotating shafts 310. The rotating shafts 310 drive the impeller 320 to rotate. The rotation of the impeller 320 can discharge the air in the air chamber 200 to the surface of the substrate between the upper chamber 210 and the lower chamber 220. At the same time, the accelerating guide plate 510 gradually narrows. This structure makes the airflow have a higher flow rate when it is discharged. With the help of the guide plate 520, the airflow can contact the surface of the substrate more stably and effectively reduce attenuation.
[0044] In summary, this utility model solves the technical problem of significant attenuation of the drying airflow velocity during operation of existing drying devices by using the guide component 500 to narrow the airflow channel and guide the airflow blown out by the drying component 300, thereby achieving the technical effect of ensuring drying effect and improving operational economy.
