[0002] Paint, traditionally known as varnish in China, is a viscous liquid that is applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object. It is usually based on resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared by mixing organic solvents or water with a stirring device.

[0003] Patent application number 202320396309.1 discloses a paint mixing device, including a mixing tank, an inlet, an outlet, a temperature regulating device, a mixing device, and a motor. This paint mixing device, through its structural design, utilizes the mixing motor to provide power for fully automatic mixing of the paint. In this invention, the mixing and lifting blades stir and lift the paint during the mixing process. The length of the scraper is adjustable according to the screw hole positions to ensure it does not stick to the walls and facilitates cleaning of the inner wall of the mixing tank. The staggered, cross-shaped mixing blades ensure more uniform and faster mixing. A thermometer monitors the temperature, and the inlet filter screen is designed to screen for particulate matter. This effectively ensures temperature balance during paint preparation, guarantees good paint performance, reduces worker labor intensity, and improves preparation efficiency.

[0004] Regarding the aforementioned technologies, the staggered mixing blades ensure more uniform and faster mixing, the thermometer monitors the temperature, and the feed inlet filter screen is designed to screen for particulate matter. This effectively ensures temperature balance during coating preparation, guarantees good coating performance, reduces labor intensity, and improves preparation efficiency. However, in this invention, the equipment does not have mixing blades at the bottom.

[0005] To solve the above problems, this utility model provides an adjustable coating mixing device, which adopts the following technical solution:

[0006] An adjustable paint mixing device includes a base, a column fixedly installed on one side of the base, a movable groove at the top of the column, a lifting block slidably installed in the movable groove, a cylinder fixedly installed on the inner wall of the bottom of the movable groove, the piston shaft end of the cylinder fixedly connected to the bottom of the lifting block, an installation plate fixedly installed on the top of the lifting block, a tank above the base, two symmetrically distributed feed pipes on the upper side wall of the tank, a collar fixedly fitted on the tank, the collar fixedly connected to the side of the column opposite to the tank, a top cover at the top of the tank, an installation frame fixedly installed on the top of the top cover, a frame fixedly fitted on the side wall of the installation plate, the bottom of the frame fixedly connected to the top of the installation frame, a mixing assembly between the installation frame and the tank, a discharge pipe at the bottom of the tank, and a control valve on the side wall of the discharge pipe.

[0007] By adopting the above technical solution, when using this equipment, the operator injects the raw materials into the tank through two feed pipes, which serves to add raw materials. After the raw materials are injected into the tank, the stirring component stirs the materials inside the tank. The stirring component can be raised and lowered within the tank to facilitate stirring of materials at different locations within the tank, which helps to improve the uniformity of material mixing. After the materials are mixed, the operator opens the control valve on the side wall of the discharge pipe to facilitate the discharge of materials through the discharge pipe. When it is necessary to clean or repair the internal components of the tank, the lifting block is driven by a cylinder to slide in the movable groove. The lifting block pushes the mounting plate, along with the mounting frame and the top cover, to rise synchronously, which separates the top cover from the tank, facilitating subsequent cleaning of the tank.

[0008] Furthermore, the stirring assembly includes a first geared motor fixedly installed on the inner wall of the top of the mounting frame. A second support plate is fixedly installed inside the mounting frame. A rotating rod is rotatably installed at the bottom of the second support plate.

Multiple second stirring rods are arranged in a straight array on the inner wall of the scrapers. The first stirring rods and second stirring rods on the same side are staggered. A lifting assembly is provided between the first support plate and the mounting frame.

[0009] By adopting the above technical solution, after the raw material is injected into the tank through the feed pipe, the first geared motor drives the rotating rod to rotate, which in turn drives the stirring blade to rotate inside the tank, thus agitating the material. Subsequently, the third geared motor drives the second main gear to rotate, which in turn drives the second auxiliary gear to rotate, which in turn drives the sleeve to rotate. The sleeve drives the first stirring rod and the scraper to rotate synchronously. The first stirring rod agitates the material, and the scraper not only agitates the material but also cleans the inner wall of the tank. The scraper drives the second stirring rod to rotate. Through the cooperation of the scraper, the first stirring rod, and the second stirring rod, the uniformity of material mixing is improved. A lifting assembly is provided between the first support plate and the mounting frame, which can drive the sleeve, scraper, first stirring rod, and second stirring rod to rise and fall synchronously, facilitating the agitation of materials at different locations inside the tank. The stirring blade not only agitates the material but also causes the material at the bottom of the tank to surge upwards, facilitating subsequent agitation. When discharge is required, the first geared motor can reverse the rotation of the rotating rod and the stirring blade, which can assist in the discharge process.

[0010] Furthermore, the lifting assembly includes a second reduction motor fixedly installed on the inner wall of the mounting frame.

The first auxiliary gear meshes with the first main gear. A slide rod symmetrically distributed with the reciprocating screw is fixedly installed on the inner wall of the top of the mounting frame. The bottom end of the slide rod slides through the first support plate.

[0011] By adopting the above technical solution, the first main gear is driven to rotate by the second reduction motor, the first main gear drives the first auxiliary gear to rotate, the first auxiliary gear drives the reciprocating screw to rotate, and the reciprocating screw drives the first support plate to rise and fall within the mounting frame. The first support plate, along with the sleeve, scraper, first stirring rod, and second stirring rod, rises and falls synchronously, thereby adjusting the position of the scraper, first stirring rod, and second stirring rod within the tank. This facilitates the stirring of materials at different locations within the tank and improves the uniformity of material stirring.

[0012] Furthermore, two symmetrically distributed grooves are provided on the inner walls of both sides of the mounting frame, and stabilizing blocks are slidably installed in the grooves. The bottom end of the stabilizing block is fixedly connected to the top end of the first support plate.

[0013] By adopting the above technical solution, when the first support plate is raised and lowered within the mounting frame, the first support plate, along with the stabilizing block, slides within the groove on the same side.
