Description

Technical Field

[0001] This invention belongs to the field of coated glass processing technology, specifically relating to a coating machine with uniform spraying effect. Background Technology

[0002] Coated glass, also known as reflective glass, is made by coating one or more layers of metal, alloy, or metal compound film onto the glass surface to change the optical properties of the glass and meet certain specific requirements. Coated glass can be divided into the following categories according to different product characteristics: heat-reflective glass, low-emissivity glass, conductive film glass, etc. In order to improve the efficiency of glass coating, a coating machine is needed.

[0003] For example, a Chinese patent discloses a coating machine capable of rapid and uniform spraying (publication number CN220610920U), which includes a support column and a spraying assembly. An upper horizontal plate is installed on the upper inner side of the support column, and a spraying assembly is provided on the upper upper part of the upper horizontal plate. The spraying assembly includes a liquid storage tank, a servo motor, a stirring rod, a liquid guide pipe, a metering spray pipe, a mounting base, a pneumatic rod, a receiving block, a movable shaft, and a coating roller.

[0004] However, the aforementioned public documents, through the setting of the spraying component, can avoid the problem of uneven film thickness on the glass caused by the difficulty in uniformly controlling the liquid output in most existing coating machines, which affects the coating quality and efficiency, when using a coating machine capable of rapid and uniform spraying. However, this patent lacks a function to clean the glass surface before coating, which easily leads to dust adhering to the glass surface. This dust causes poor coating results during the coating process, thus limiting its applicability. Therefore, those skilled in the art have provided a solution to address the problems mentioned in the background art. Utility Model Content

[0025] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe a coating machine with uniform spraying effect or several specific embodiments of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1 and Figure 3 As shown, a coating machine with uniform spraying effect includes a base 1. Support plates 2 are fixed at both ends of the outer top surface of the base 1. Several conveyor rollers 3 are rotatably installed at the center position between the two support plates 2. The two ends of the conveyor rollers 3 extend to the opposite outer side walls of the two support plates 2 and are connected to each other by connectors. Mounting blocks 10 are fixed at the bottom of the outer walls on both the front and rear sides of the base 1. The outer top surface of the two mounting blocks 10 is provided with through screw holes. By tightening the bolts in the screw holes, the base 1 is fixed in a designated position through the mounting blocks 10, thereby ensuring the normal operation of the subsequent equipment and facilitating the disassembly and assembly of the equipment. It has high flexibility. At the same time, the connectors can drive the several conveyor rollers 3 to rotate synchronously in the same direction, thereby driving the coated glass to be transported and moved to complete the coating operation.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, a cleaning assembly 4 for cleaning the coated glass surface is provided between the two support plates 2 and at the input end of the corresponding conveyor roller 3. The cleaning assembly 4 includes a first cleaning roller 401 and a second cleaning roller 402 arranged symmetrically between the two support plates 2. Square covers 403 are symmetrically provided on the corresponding outer walls of the two support plates 2. The front and rear ends of the first cleaning roller 401 and the second cleaning roller 402 are respectively engaged in the inner sides of the two square covers 403 and are threaded together by positioning screws 404. Round rods 405 and 406 are respectively fixed on the opposite outer walls of the two square covers 403. One end of each round rod 405 extends rotatably to the left outer wall of one of the support plates 2, and a gear 407 is fixed on the outer peripheral side wall of each. The two gears 407 are meshed. One end of each round rod 406 extends rotatably to the other support plate 2. On the right outer wall of the support plate 2, a drive motor 408 is fixedly installed. The output end of the drive motor 408 is fixedly connected to one of the round rods 406. In use, the controller controls and starts the drive motor 408. Under the meshing connection of the two gears 407, the round rods 405 and 406 drive the cleaning rollers 401 and 402 to rotate synchronously in opposite directions. This drives the coated glass to move forward, thereby removing dust from the outer surface of the coated glass by cleaning the lint on the cleaning rollers 401 and 402. At the same time, turning the positioning screw 404 allows the two ends of the cleaning rollers 401 and 402 to be separated from the inside of the square cover 403, making it easy to disassemble and replace the cleaning rollers 401 and 402, thus improving practicality.

[0028] like Figure 1 , Figure 5 and Figure 6As shown, a spraying assembly 5 is provided on the outer top surface of the two support plates 2. The spraying assembly 5 includes a bracket 501 fixed to the right end of the outer top surface of the two support plates 2. A liquid storage cylinder 502 is fixed between the two brackets 501. A cross plate 503 is fixed between the two support plates 2. A rotating shaft 504 is rotatably installed inside the liquid storage cylinder 502. One end of the rotating shaft 504 extends rotatably to the rear outer wall of the liquid storage cylinder 502 and a gear 505 is fixed to its outer peripheral side wall. The other end extends rotatably to the front outer wall of the liquid storage cylinder 502. A gear 506 is fixed to the outer peripheral side wall of one of the conveying rollers 3. The gear 505 and the gear 506 are connected by a toothed chain 507. The liquid storage tank 502 is connected to the rotating shaft 504. A second drive motor 508 is fixed to the front outer wall of the liquid storage tank 502. The output end of the second drive motor 508 is fixedly connected to the rotating shaft 504. An inlet pipe 6 is fixedly and continuously connected to the bottom of the outer peripheral side wall of the liquid storage tank 502. U-shaped scrapers 7 are symmetrically installed at both ends of the outer peripheral side wall of the rotating shaft 504 inside the liquid storage tank 502. Several stirring blades 8 are symmetrically installed at the center of the outer peripheral side wall of the rotating shaft 504. In use, the valve on the inlet pipe 6 is first opened to transport the coating solution into the interior of the liquid storage tank 502 along the inlet pipe 6. Then, the controller controls and starts the second drive motor 508 to drive the rotating shaft 504 to rotate. This drives the U-shaped scraper 7 and stirring blades 8 to stir the coating solution in the storage tank 502, thereby preventing the coating solution from settling. At the same time, the rotating shaft 504 drives the conveyor roller 3 to rotate synchronously through the interaction of gear 2 505, gear 3 506 and gear chain 507, thereby reducing the power source and improving practicality.

[0029] like Figure 6 As shown, connecting plates 509 are fixed at both ends of the bottom surface of the horizontal plate 503. A diversion pipe 510 is fixed between the two connecting plates 509. Several nozzles 511 are fixed and connected to the bottom of the outer side wall of the diversion pipe 510. A suction pump 512 is installed on the top surface of the horizontal plate. The input end of the suction pump 512 is connected to the liquid storage tank 502 through the first pipe 513, and the output end is connected to the diversion pipe 510 through the second pipe 514. First, the valve on the first pipe 513 is opened, and then the suction pump 512 is started by the controller to generate suction, so as to transport the coating liquid inside the liquid storage tank 502 along the first pipe 513 and the second pipe 514 to the inside of the diversion pipe 510. Then, it is sprayed out through several nozzles 511 to evenly spray the coating liquid onto the outer surface of the coated glass, thereby improving the coating quality of the coated glass to a certain extent.

[0030] like Figure 1 and Figure 3As shown, a leveling component 9 is provided between the two support plates 2 and at the output end of the corresponding conveyor roller 3. The leveling component 9 includes a horizontal plate 901 fixed between the two support plates 2. A U-shaped frame 902 is provided on the outer bottom surface of the horizontal plate 901. A coating roller 903 is rotatably installed inside the U-shaped frame 902. An electric push rod 904 is fixed at the center of the outer top surface of the horizontal plate 901. The output end of the electric push rod 904 slides to the outer bottom surface of the horizontal plate 901 and is fixedly connected to the outer top surface of the U-shaped frame 902. When the outer surface of the coated glass is coated and conveyed by the conveyor roller 3 to the area below the coating roller 903, the controller controls and starts the electric push rod 904 to move the U-shaped frame 902 downward, thereby driving the coating roller 903 to contact the outer surface of the coated glass to roll the coating liquid evenly sprayed on the glass, thereby improving the overall efficiency of the coating machine, achieving a fast and uniform spraying effect, and increasing its applicability.

[0031] like Figure 1 and Figure 3 As shown, a recycling component 11 is provided inside the base 1. The structure and working principle of the recycling component 11 have been disclosed in a coating machine that can quickly and evenly spray coating, which is published in Chinese Patent Publication No. CN220610920U. Its working principle is that while the coating roller 903 rolls the coating liquid, the excess coating liquid flows onto the base 1 with the conveyor roller 3. The coating liquid flows into the interior of the base 1 through the through hole opened at the upper end of the base 1, and is transported to the infusion pipe by the liquid collection plate. The coating liquid is filtered by the filter frame connected to the front end of the infusion pipe, thereby avoiding the waste of the coating liquid.

[0032] The working principle of this utility model is as follows: When in use, the coated glass is first placed between cleaning roller 1 401 and cleaning roller 2 402, with its front end in contact with the outer surface of the conveyor roller 3. Then, the drive motor 1 408 is started, and under the meshing connection of gear 1 407, it drives the round rod 1 405 and round rod 2 406 to drive the cleaning roller 1 401 and cleaning roller 2 402 to rotate synchronously in opposite directions, thereby driving the coated glass to move forward. Thus, the dust on the outer surface of the coated glass is removed by cleaning the lint on the cleaning roller 1 401 and cleaning roller 2 402.

[0033] Simultaneously, the drive motor 508 is started to drive the rotating shaft 504 to rotate, thereby driving the U-shaped scraper 7 and the stirring blade 8 to stir the coating solution in the storage tank 502 to prevent the coating solution from settling. At the same time, during the rotation of the rotating shaft 504, the interaction of gear 2 505, gear 3 506 and gear chain 507 synchronously drives the conveyor roller 3 to rotate, thereby driving the coated glass to be conveyed and moved.

[0034] At the same time, the suction pump 512 is started to transport the coating liquid inside the liquid storage cylinder 502 along the pipe 1 513 and the pipe 2 514 to the inside of the diversion pipe 510, and then through several nozzles 511 to evenly spray the coating liquid onto the outer surface of the coated glass.

[0035] Next, the electric push rod 904 is activated to move the U-shaped frame 902 downwards, thereby driving the coating roller 903 to contact the outer surface of the coated glass, so as to roll the coating liquid evenly sprayed on the glass, thereby achieving a fast and uniform coating effect.

[0036] Finally, the excess coating solution is recycled using the recycling component 11. (It should be noted that all electrical components mentioned in this article are electrically connected to an external power source, and the control method in this invention is controlled by a PLC controller. The control circuit of the PLC controller can be implemented by those skilled in the art through programming, and thus can operate normally according to the above steps. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.)

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
