[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3The conveying assembly 210 comprises a driving shaft 211, a driven shaft 212 and a conveying belt 213. The driving shaft 211 is horizontally arranged at one end of the box and penetrates the box. The driven shaft 212 is horizontally arranged at the other end of the box and penetrates the box. The driven shaft 212 corresponds to the driving shaft 211. The conveying belt 213 is a closed belt and is arranged around the driving shaft 211 and the driven shaft 212. The first driving assembly 220 comprises a transmission part 221 and a driving part 222. The transmission part 221 is connected with each driven shaft 212 to make the adjacent driven shaft 212 rotate reversely. The driving part 222 is connected with one driving shaft 211 to drive the corresponding driving shaft 211 to rotate. By controlling the driving part 222, the driving part 222 drives the corresponding driving shaft 211 to rotate, and then the corresponding conveying belt 213 drives the corresponding driven shaft 212 to rotate, so that the corresponding conveying belt 213 makes circular reciprocating motion. During the rotation of the driven shaft 212, the transmission part 221 is connected with each driven shaft 212 to make the adjacent driven shaft 212 rotate reversely, so that the conveying directions of the adjacent conveying belts 213 are opposite. The multiple conveying belts 213 arranged from top to bottom can form a complete conveying line. The driving part 222 is a motor of appropriate type. The output end of the motor can be coaxially fixedly connected with one driving shaft 211, or the motor can be connected with the driving shaft 211 through a gear set or a sliding set.

[0027] As a preferred embodiment, refer to Figure 2 and Figure 3 The transmission part 221 comprises multiple first gears 2211. Each first gear 2211 is coaxially fixedly connected with one end of each driven shaft 212. The adjacent first gears 2211 are engaged with each other to convert the rotation of the last layer of driven shaft 212 into the reverse rotation of the next layer of driven shaft 212. By controlling the driving part 222, the driving part 222 drives the corresponding driving shaft 211 to rotate, and then the corresponding conveying belt 213 drives the corresponding driven shaft 212 to rotate, so that the corresponding conveying belt 213 makes circular reciprocating motion. During the rotation of the driven shaft 212, the corresponding first gear 2211 rotates synchronously. Since the adjacent gears are engaged with each other, the adjacent driven shaft 212 can rotate reversely, so that the conveying directions of the adjacent conveying belts 213 are opposite. The multiple conveying belts 213 arranged from top to bottom can form a complete conveying line.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 2 The photosensitizer drying device further includes a dispersing mechanism 300, which includes multiple dispersing rollers 310 and a second drive assembly 320. Each of the dispersing rollers 310 is disposed inside the housing 100 and is located above the corresponding conveyor belt 213. The second drive assembly 320 is connected to each of the dispersing rollers 310 and is used to drive each of the dispersing rollers 310 to rotate synchronously, so that each of the dispersing rollers 310 disperses the clumps of wet product on the corresponding conveyor belt 213. Since a small portion of the wet photosensitizer tends to clump together during the drying process, the internal parts of the wet product clumps may not be completely dried, resulting in a poor drying effect for the wet photosensitizer. By operating the second drive assembly 320, the second drive assembly 320 can drive each of the dispersing rollers 310 to rotate synchronously, thereby dispersing the photosensitizer on each of the conveyor belts 213 and improving the drying effect.

[0029] As a preferred embodiment, please refer to Figure 2 and Figure 3 The second drive assembly 320 includes multiple drive shafts 321, multiple second gears 322, and multiple transmission components 323. Each drive shaft 321 is horizontally positioned at intervals from top to bottom in the middle of the housing 100 and rotatably passes through the housing 100. Each driven shaft 212 corresponds one-to-one with each other. Each second gear 322 is coaxially and fixedly connected to one end of each drive shaft 321. Each second gear 322 also meshes with each first gear 2211 to convert the rotation of each driven shaft 212 into the opposite rotation of the corresponding drive shaft 321. One end of each transmission component 323 is connected to one end of each drive shaft 321. The other end of each transmission component 323... The end is connected to one end of each of the dispersing rollers 310 to convert the rotation of each of the transmission shafts 321 into the same-direction rotation of the corresponding dispersing rollers 310. Since each of the second gears 322 and each of the first gears 2211 mesh with each other, when each of the first gears 2211 rotates, the corresponding second gear 322 will rotate in the opposite direction, and thus the corresponding transmission shaft 321 will rotate in the opposite direction. Since the transmission component 323 can convert the rotation of the transmission shaft 321 into the same-direction rotation of the corresponding dispersing rollers 310, the rotation direction of the dispersing rollers 310 can be opposite to the conveying direction of the corresponding conveyor belt 213. While dispersing the wet product clumps, the wet product clumps can be pushed downwards to prevent the wet product clumps from accumulating at the dispersing rollers 310.

[0030] As a preferred embodiment, please refer to Figure 3 Each of the aforementioned transmission components 323 is a belt pulley transmission structure, which ensures that the transmission direction does not change during transmission operations.

[0031] As a preferred embodiment, please refer to Figure 2 The dispersing roller 310 has a brush roller structure. The densely packed bristles on the dispersing roller 310 can disperse the wet product clumps and also spread the photosensitizer evenly on the conveyor belt 213.

[0032] As a preferred embodiment, please refer to Figure 2 and Figure 3 The conveying mechanism 200 also includes a plurality of guide plates 230, each of which is disposed at the beginning of the corresponding conveyor belt 213, for guiding the photosensitizer on the upper conveyor belt 213 to the lower conveyor belt 213, thereby allowing the photosensitizer on the upper conveyor belt 213 to reach the lower conveyor belt 213 smoothly, avoiding spillage of the photosensitizer and ensuring the conveying effect.

[0033] As a preferred embodiment, please refer to Figure 3 The guide plate 230 has a vertical section 231 and an arc-shaped section 232 that are fixedly connected to each other. The vertical section 231 is located on the side of the end of the upper layer conveyor belt 213 and has a gap between it and the end of the upper layer conveyor belt 213. The lower end of the arc-shaped section 232 abuts against the surface of the lower layer conveyor belt 213. The vertical section 231 can block the photosensitizer on the upper layer conveyor belt 213, and the arc-shaped section 232 can guide the photosensitizer to the lower layer conveyor belt 213.

[0034] As a preferred embodiment, please refer to Figure 1 and Figure 2 The housing 100 also has multiple air inlets 130, each of which is located at the end of the corresponding conveyor belt 213. The hot air mechanism is a hot air blower, the outlet of which is connected to each of the air inlets 130 to blow hot air into the space above each of the conveyor belts 213. The hot air moves from the end of the conveyor belt 213 to the beginning of the conveyor belt 213, which can improve the drying effect on the photosensitizer.

[0035] In a preferred embodiment, the photosensitizer drying device further includes a suction mechanism, which is a blower. The inlet of the blower is connected to the top of the box 100 to extract the exhaust gas inside the box 100. When the photosensitizer drying is completed, the blower is turned on to extract the exhaust gas inside the box 100.

[0036] As a preferred embodiment, please refer to Figure 3 The feed inlet 110 is located at the top of the box 100, and the discharge outlet 120 is located at the bottom of the box 100, so that the photosensitizer entering the box 100 can fall onto the top conveyor belt 213, and the photosensitizer on the bottom conveyor belt 213 can fall into the discharge outlet 120 and be discharged along the discharge outlet 120.

[0037] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of the technical solution of this utility model will be described in detail below:

[0038] In use, the feed inlet 110 is connected to the outlet of the upstream processing step, and the discharge outlet 120 is connected to the inlet of the downstream processing step. The photosensitizer enters the housing 100 through the feed inlet 110 and falls onto the top conveyor belt 213. By operating the rotation drive 224, the output end of the rotation drive 224 rotates, which drives the corresponding active shaft 211 to rotate. Then, via the corresponding conveyor belt 213, the corresponding driven shaft 212 rotates, causing the corresponding conveyor belt 213 to perform a circular reciprocating motion. During the rotation of the driven shaft 212, the corresponding first gear 2211 rotates synchronously. Since adjacent gears mesh with each other, adjacent driven shafts 212 can rotate in opposite directions, thus causing the conveying directions of adjacent conveyor belts 213 to be opposite, thereby making... The adjacent conveyor belts 213 are connected end to end to form a complete conveyor line. When the photosensitizer reaches the end of the upper conveyor belt 213, it will fall onto the lower conveyor belt 213 and be conveyed downwards layer by layer. When the photosensitizer reaches the bottom conveyor belt 213, it will be conveyed to the end by the bottom conveyor belt 213 and discharged along the discharge port 120. Hot air can be blown into the space above each conveyor belt 213 by the hot air fan. The hot air moves from the end of the conveyor belt 213 to the beginning of the conveyor belt 213, thereby drying the photosensitizer on the conveyor belt 213. This can improve the drying effect of the photosensitizer. This drying device increases the conveying distance of the photosensitizer by using multiple conveyor belts 213 arranged at intervals from top to bottom. When arranging the annealing device, it will not occupy a lot of area and is suitable for use in small factories.

[0039] The photosensitizer drying device provided by this utility model has the following beneficial effects:

[0040] (1) Each of the air inlets 130 is located at the end of the corresponding conveyor belt 213. The hot air mechanism is a hot air blower. The outlet end of the hot air blower is connected to each of the air inlets 130. Hot air is blown into the space above each of the conveyor belts 213. The hot air moves from the end of the conveyor belt 213 to the beginning of the conveyor belt 213, which can improve the drying effect of the photosensitizer.

[0041] (2) When drying photosensitizers, a small portion of wet photosensitizers tend to clump together, which can lead to the clumps not being completely dried and resulting in poor drying effect. By controlling the second drive component 320, the second drive component 320 can drive each of the dispersing rollers 310 to rotate synchronously. The dispersing rollers 310 can disperse the photosensitizers on each of the conveyor belts 213, thereby breaking up the wet clumps and improving the drying effect.

[0042] (3) This drying device increases the conveying distance of photosensitizer by using multiple conveyor belts 213 arranged at intervals from top to bottom. When arranging the annealing device, it will not occupy a lot of area and is suitable for use in small factories.
