Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, and particularly relates to a doctor blade coater for plastic plates. Background Technique

[0002] A doctor blade coater for plastic plates is a special machine for evenly coating paint on plastic plates. It mainly transports the plastic plates to the coating area through a conveying mechanism, and makes the paint evenly coated on the surface of the plastic plates through a doctor blade.

[0003] However, when the common doctor blade coater for plastic plates applies paint, it generally uses manual feeding, that is, manually operates to smear the paint on the front end of the doctor blade, and then smears it evenly through the doctor blade. However, manual feeding is not only time-consuming and laborious, but also difficult to control the feeding amount.

[0004] Therefore, we propose a doctor blade coater for plastic plates with automatic feeding to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a doctor blade coater for plastic plates. By installing a feeding mechanism, the storage box and the extrusion plate can cooperate with each other to achieve the purpose of automatic feeding, so as to solve the problems raised in the above background technique.

The upper surface of the conveying mechanism is fixedly connected with a coating mechanism and a feeding mechanism, and the feeding mechanism is located in front of the coating mechanism;

[0007] A second motor is installed on the upper surface of the coating mechanism. A threaded rod and a lifting block are arranged inside the coating mechanism. A mounting plate is fixedly connected to the side surface of the lifting block, and a doctor blade is fixedly connected to the lower surface of the mounting plate.

[0008] A storage box is fixedly installed at the lower end of the inner surface of the feeding mechanism, and a cylinder is installed on the upper surface of the feeding mechanism. The output end of the cylinder is connected with an extrusion plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6 , a knife coater for plastic plates, which includes a base 1 and a conveying mechanism 2. The upper surface of the conveying mechanism 2 is fixedly connected with a coating mechanism 3 and a feeding mechanism 4. The feeding mechanism 4 is located at the front end of the coating mechanism 3. A second motor 31 is installed on the upper surface of the coating mechanism 3. A threaded rod 32 and a lifting block 33 are arranged inside the coating mechanism 3. The side surface of the lifting block 33 is fixedly connected with a mounting plate 34, and a knife 341 is fixedly connected to the lower surface of the mounting plate 34. A storage box 41 is fixedly installed at the lower end of the inner surface of the feeding mechanism 4. A cylinder 42 is installed on the upper surface of the feeding mechanism 4. The output end of the cylinder 42 is connected with a pressing plate 43. According to the required coating thickness, the distance between the knife 341 and the conveyor belt 24 is adjusted. Then, the plastic plate is placed on the conveyor belt 24 and slowly moved towards the coating mechanism 3 and the feeding mechanism 4. When the plastic plate moves to the lower end of the feeding mechanism 4, the coating material is loaded into the storage box 41. At this time, the coating material will slowly slide down to the surface of the plastic plate through the feeding port 411. When the feeding is slow, the cylinder 42 can be driven. The cylinder 42 drives the pressing plate 43 to press down, so that the pressing plate 43 enters the storage box 41 and applies pressure to the coating material to make the coating material discharge quickly.

[0024] Furthermore, the upper surface of the base 1 is fixedly connected with the lower surface of the conveying mechanism 2. A first motor 21 is installed on the outer surface of the conveying mechanism 2. A driving roller 22 and a driven roller 23 are rotatably connected to the inner surface of the conveying mechanism 2. During use, by driving the first motor 21, the first motor 21 drives the driving roller 22 to rotate, and then the conveyor belt 24 can be driven in cooperation with the driven roller 23 to convey the plastic plate.

[0025] Furthermore, the output end of the first motor 21 penetrates through the conveying mechanism 2 and is in transmission connection with the driving roller 22. A plurality of driven rollers 23 are provided. The conveyor belt 24 is sleeved on the outer surfaces of the driving roller 22 and the driven roller 23. During use, by providing a plurality of driven rollers 23, the stability of the conveyor belt 24 can be ensured, and thus the plastic plate can be stably conveyed.

[0026] Further, the output end of the second motor 31 penetrates into the interior of the coating mechanism 3 and is in transmission connection with the threaded rod 32. The outer surface of the threaded rod 32 is threadedly connected to the lifting block 33. During use, the second motor 31 can be driven. The second motor 31 drives the threaded rod 32 to rotate, thereby driving the lifting block 33 to lift and lower. Then, the scraper 341 is driven to lift and lower through the mounting plate 34. By controlling the distance between the scraper 341 and the conveyor belt 24, the coating thickness can be freely adjusted.

[0027] Further, the interior of the material storage box 41 is provided with coating material. A material discharging port 411 is formed in the lower surface of the material storage box 41. The output end of the air cylinder 42 penetrates through the upper end of the material discharging mechanism 4 and is fixedly connected to the upper surface of the pressing plate 43. During use, the material storage box 41 is provided for storing the coating material, and the material is slowly discharged through the material discharging port 411, so as to facilitate the subsequent coating of the plastic plate by the scraper 341.

[0028] Working principle: For a scraper coater for plastic plates of the present utility model, during use, first, the base 1 serves as a stable foundation for the entire machine and is used to support the conveying mechanism 2. The conveying mechanism 2 drives the driving roller 22 to rotate through the first motor 21, thereby driving the conveyor belt 24 cooperating with a plurality of driven rollers 23 to move smoothly, and then realizing the continuous and stable conveyance of the plastic plate. When the plastic plate is conveyed to the lower positions of the coating mechanism 3 and the material discharging mechanism 4, the operator drives the second motor 31 according to the required coating thickness, making it drive the threaded rod 32 to rotate, and then driving the lifting of the mounting plate 34 and the scraper 341 through the lifting block 33. By adjusting the distance between the scraper 341 and the conveyor belt 24, the precise adjustment of the coating thickness can be achieved. The material storage box 41 in the material discharging mechanism 4 is used for loading the coating material and slowly releases it onto the surface of the plastic plate through the material discharging port 411. If the discharging speed of the coating material is too slow, the air cylinder 42 can be started. The air cylinder 42 pushes the pressing plate 43 to apply pressure to the coating material in the material storage box 41, which can accelerate the outflow of the coating material and ensure that the scraper can evenly coat the coating material on the surface of the plastic plate, thereby completing the coating operation.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
