Description

Technical Field

[0001] The utility model belongs to the technical field of continuous spraying devices for acrylic plates, and particularly relates to a continuous spraying device for acrylic plates. Background Technique

[0002] Acrylic plates, also known as plexiglass, have been widely used in many fields due to their good transparency, weather resistance, easy processing and other advantages. It is used in industries such as architectural decoration, advertising signs, furniture manufacturing, lighting fixtures, etc. With the continuous growth of market demand, higher requirements are put forward for the surface treatment quality and efficiency of acrylic plates. In the past, the spraying of acrylic plates often adopted manual spraying or simple mechanical spraying methods. However, manual spraying is not only inefficient, but also the spraying quality largely depends on the technical level and experience of the operators, and it is difficult to ensure the uniformity and consistency of the coating. Therefore, machine spraying is mostly used nowadays.

[0003] However, when some existing continuous spraying devices are in use, the acrylic plate may shake left and right or move back and forth during the conveying process, resulting in the paint sprayed by the spray gun being unable to accurately cover the predetermined area, causing the spraying position to shift. Content of the Utility Model

[0004] The purpose of the utility model is to provide a continuous spraying device for acrylic plates. By setting a limiting mechanism, the problem that the acrylic plate may shake left and right or move back and forth during the conveying process, resulting in the paint sprayed by the spray gun being unable to accurately cover the predetermined area and causing the spraying position to shift is solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a continuous spraying device for acrylic plates, including two support frames. A limiting mechanism and a drying mechanism are arranged on the two support frames;

[0007] Two rotating shafts I are rotatably connected between the two support frames. The two rotating shafts I are respectively located on the left and right sides of the two support frames. The two rotating shafts I both rotatably penetrate through the outer wall of the front support frame and extend to the outside. Circular rollers are fixedly connected to the outer walls of the two rotating shafts I. A conveyor belt is sleeved on the two circular rollers. C-shaped frames I are fixedly connected to the tops of the two conveyor belts. A spraying machine is fixedly connected to the tops of the two C-shaped frames I. An acrylic plate body is arranged on the top of the conveyor belt. The limiting mechanism includes a limiting component I and a limiting component II. The limiting component I includes C-shaped frames II that are respectively slidably connected to the inner walls of the two C-shaped frames I.

[0008] Furthermore, a number of telescopic rods are fixedly connected to the inner walls of both of the U-shaped frames one. The telescopic rods are respectively fixedly connected to the two U-shaped frames two on the side close to the conveyor belt. Springs are sleeved on the outer walls of the telescopic rods. The springs are respectively fixedly connected to the two U-shaped frames two on the side close to the conveyor belt. The springs are respectively fixedly connected to the two U-shaped frames one on the side far from the conveyor belt.

[0009] Furthermore, the limiting component two includes a number of rotating shafts two respectively rotatably connected to the inner walls of the two U-shaped frames two. Roller wheels are fixedly connected to the outer walls of the rotating shafts two. The roller wheels are in contact with the acrylic plate body on the side close to the conveyor belt.

[0010] Furthermore, the air-drying mechanism includes an air-drying component and a driving component. The air-drying component includes a U-shaped frame three fixedly connected to the tops of the two U-shaped frames one. A rotating shaft three rotatably penetrates through the central axis of the U-shaped frame three. A fan is fixedly connected to the bottom extension of the rotating shaft three.

[0011] Furthermore, a rotating groove is formed at the central axis of the U-shaped frame three. A clamping ring is fixedly connected to the outer wall of the rotating shaft three. The outer wall of the clamping ring rotatably extends into the rotating groove.

[0012] Furthermore, the driving component includes a motor fixedly connected to the front extension of the rotating shaft one on the left side. A U-shaped support plate is fixedly connected to the top of the U-shaped frame one at the front side.

[0013] Furthermore, a rotating shaft four rotatably penetrates through the U-shaped support plate. Bevel gears are fixedly connected to the outer walls of the rotating shaft three and the rotating shaft four. The two bevel gears are meshed with each other.

[0014] Furthermore, pulley wheels are fixedly connected to the front extensions of the rotating shaft one and the pair of rotating shaft four on the right side. A belt is sleeved on the two pulley wheels.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting a limiting mechanism, when the acrylic plate body is placed on the conveyor belt, the acrylic plate body will first come into contact with the roller. The roller will stretch or compress the telescopic rod and the spring under the cooperation of the second rotating shaft and the second C-shaped frame, so as to adapt to the size of the acrylic plate body and limit it. When the acrylic plate body moves forward, the roller on the second rotating shaft will rotate accordingly, preventing the acrylic plate body from being stuck due to limitation, ensuring that the acrylic plate can maintain a stable position during the conveying process. The spray gun can accurately spray the paint on the predetermined area, ensuring the accuracy of the sprayed pattern, color, and coating thickness, keeping a constant distance and angle between the acrylic plate and the spray gun, so as to ensure that the paint evenly covers the surface of the plate and avoid the situation of local over-thickness or under-thickness.

[0017] 2. By setting a drying mechanism, while the first rotating shaft drives the conveyor belt to rotate and the acrylic plate body moves forward, the first rotating shaft will also drive the fourth rotating shaft to rotate through the pulley and belt. The fourth rotating shaft drives the third rotating shaft on the third C-shaped frame to rotate through the third rotating shaft, thereby driving the fan to rotate and drying the acrylic plate body, which can accelerate the drying speed of the paint on the surface of the acrylic plate, shorten the production cycle, improve production efficiency, help form a smooth, uniform, and firm coating, and also reduce the possibility of the acrylic plate adsorbing dust when exposed to the air before being completely dried.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

After the acrylic board body 106 is placed on the conveyor belt 103, the motor 321 can be started. The motor 321 drives the conveyor belt 103 on the round roller 102 to rotate through the rotating shaft one 101, so as to convey the acrylic board body 106 forward. At this time, start the spraying machine 105 to spray the acrylic board body 106. While the rotating shaft one 101 drives the conveyor belt 103 to rotate and the acrylic board body 106 moves forward, the rotating shaft one 101 will also drive the rotating shaft four 323 to rotate through the pulley wheel 325 and the belt 326. The rotating shaft four 323 drives the rotating shaft three 312 on the C-shaped frame three 311 to rotate through the rotating shaft three 312, thereby driving the fan 313 to rotate and air-drying the acrylic board body 106, so as to accelerate the drying speed of the paint on the surface of the acrylic board, thereby shortening the production cycle, improving the production efficiency, helping to form a smooth, uniform and firm coating, and also reducing the possibility that the acrylic board adsorbs dust when it is exposed to the air before being completely dried.
