These slides 3 are precisely designed to ensure that the frame 4 can slide smoothly. The tops of multiple slides 3 are slidably connected to the frame 4, so that the frame 4 can move relative to the slide 3, thereby realizing the mutual merging or separation of the frames 4 to adapt to different production needs. The right side of the left frame 4 is fixedly connected with a mounting frame 5, and the two mounting frames 5 are rotatably connected with rubber rollers 6 between the adjacent ones. These rubber rollers 6 are key components in the coating process and are responsible for evenly coating the coating on the LED roller coating line.

[0041] Reference Figure 3 and Figure 5The adjusting mechanism 2 includes two cylinders 201. The adjacent ends of the two cylinders 201 are fixedly connected to the front and rear sides of the frame 4. The two cylinders 201 are installed on the front and rear sides of the left frame 4 to ensure the stability and firmness of the cylinders 201 during operation. One end of the two cylinders 201 passes through the front and rear sides of the frame 4 and is fixedly connected to a connecting piece 202. The right sides of the two connecting pieces 202 are rotatably connected to a rotating plate 203. The middle parts of the two rotating plates 203 are rotatably connected through a rotating shaft 204. The right sides of the two rotating plates 203 are rotatably connected to a connecting piece 207. Connecting piece 2 02 and the second connecting piece 207 are connected by a cross rotating plate 203, and are connected by a rotating shaft 204 at the intersection of the rotating plates 203. The right sides of the two second connecting pieces 207 are slidably connected with an adjusting frame 205. The internal rotation of the adjusting frame 205 is connected with a roller 206. By starting the cylinder 201 to drive the connecting piece 1 202 to drive the rotating plates 203 to squeeze each other, the connecting piece 207 drives the adjusting frame 205 to slide left and right, so that the distance between the roller 206 and the rubber roller 6 can be adjusted to each other. This makes it easier to clean and disassemble the roller 206 in the later stage.

[0042] Specifically, the two cylinders 201 are precisely mounted on the front and rear sides of the left frame 4, and the adjacent ends are fixedly connected to ensure close integration with the frame 4. This design greatly enhances the stability and firmness of the cylinders 201 during operation; in addition, one end of the two cylinders 201 also cleverly penetrates the front and rear sides of the frame 4 and is fixedly connected to a connecting piece 1 202, which enables the telescopic action of the cylinder to be directly transmitted to subsequent components; the right side of the connecting piece 1 202 is tightly connected to the rotating plate 203 by a rotating connection. The two rotating plates 203 not only serve as a bridge between the connecting piece 1 202 and the subsequent components, but also realize a flexible rotating connection through the middle rotating shaft 204. This design allows the rotating plate 203 to rotate smoothly when subjected to external force, thereby driving the entire adjusting mechanism to move; on the right side of the rotating plate 203, the connecting piece 2 207 is also connected by a rotating connection, and the connecting piece 1 202 and the connecting piece 2 207 are connected by a rotating connection. The cross-connection method not only enhances the stability of the mechanism, but also enables the mechanism to maintain a certain balance during movement; at the same time, the cross position of the rotating plate 203 is further connected by the rotating shaft 204, which further ensures the smoothness and stability of the rotating plate during rotation; the right side of the connecting piece 207 is connected to the adjusting frame 205 by a sliding connection. This sliding connection allows the adjusting frame 205 to slide left and right along a certain trajectory when subjected to external force, and the interior of the adjusting frame 205 is rotatably connected to the roller 206. The roller 206 is a key component that contacts and cooperates with the rubber roller 6. The adjustment of its position directly affects the working effect of the entire mechanism; when the distance between the roller 206 and the rubber roller 6 needs to be adjusted, it is only necessary to start the cylinder 201. The telescopic movement of the cylinder will drive the connecting piece 1 202 to move, thereby driving the rotating plates 203 to squeeze each other. This squeezing action will be transmitted to the second connecting piece 207 and eventually cause the adjustment frame 205 to slide left and right. Through such a design, the distance between the roller 206 and the rubber roller 6 can be accurately adjusted to meet different work requirements. At the same time, this adjustment method also facilitates subsequent cleaning work and quick disassembly and replacement of the roller 206.

The outer walls of the filter tanks 13 are fixedly connected to reinforcement plates 20. The bottoms of the two reinforcement plates 20 are fixedly connected to the inner top of the support frame 21. The front side of the support frame 21 is fixedly connected to a placement frame 23, and the top of the placement frame 23 is fixedly connected to a control box 24.

[0044] Specifically, the support frame 21 serves as the main load-bearing structure, ensuring the stability of the transfer platform 1. A plurality of rubber pads 22 are installed at the bottom end of the support frame 21 to play the role of shock absorption, anti-slip and noise reduction, effectively protecting the bottom of the equipment from damage and improving the comfort during operation; in order to further enhance the structural strength of the filter tank 13, a reinforcement plate 20 is fixedly connected to the outer wall, and the reinforcement plate 20 fits tightly with the filter tank 13 to ensure the stability of the tank body. The bottoms of the two reinforcement plates 20 are respectively fixedly connected to the inner top of the support frame 21, forming a stable support system, which effectively prevents the vibration or displacement of the filter tank 13 during operation, and facilitates simple operation and control of the operating equipment on the entire device through the control box 24.

[0045] Working principle: First, the relative movement between the racks 4 is achieved through the slide 3, so that the racks 4 are merged with each other to realize the later coating process. The protective cover 8 is installed and connected through the sealing connecting plate 7 on the top of the rack 4. The protective cover 8 can prevent external dust from entering and the paint from splashing. The external air can be sucked through the air inlet pipe 10 to realize the internal ventilation treatment. At the same time, the filter air inlet box 11 can prevent external dust from entering, thereby improving the air quality. By starting the vacuum cleaner 18, the harmful gas inside the rack 4 is transported into the filter tank 13 through the exhaust pipe 12, and the filter screen in the filter tank 13 is used to remove the harmful gas. 14. The sponge plate 15 and the activated carbon plate 16 filter the gas, thereby improving environmental protection and preventing the escape of harmful gases. The connector 1 202 and the connector 2 207 are connected by a cross rotating plate 203, and are connected by a rotating shaft 204 at the intersection of the rotating plates 203. The cylinder 201 is started to drive the connector 1 202 to drive the rotating plates 203 to squeeze each other, so that the connector 2 207 drives the adjustment frame 205 to slide left and right, so that the distance between the roller 206 and the rubber roller 6 can be adjusted to each other, which can facilitate the later cleaning and disassembly of the roller 206.
