Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, and in particular to a raw material screening device for coating processing with a material clearing structure. Background Technology

[0002] Coatings are liquid or solid materials that are applied to the surface of an object and form a thin film under certain conditions to provide protection, decoration, or other special functions (insulation, rust prevention, mildew prevention, heat resistance, etc.). Because early coatings were mostly made from vegetable oils, they were also called paints. Now, synthetic resins have replaced vegetable oils, hence the name coatings. Coatings are not always liquid. Powder coatings are a major category of coatings. During the reprocessing of coatings, the raw materials need to be screened, which increases the quality of the coatings produced in the later stages.

[0003] Chinese Patent Publication No. CN211275427U discloses a screening device for processing coating raw materials. The device comprises a sliding groove on both sides of the inner cavity of the housing, a slider slidably connected to the inner cavity of the sliding groove, a screen fixedly connected to the inner side of the slider, a driving assembly on the back of the housing, and a second sliding groove on the bottom left side of the inner cavity of the housing. A feeding plate is slidably connected to the inner cavity of the second sliding groove via the slider. This invention utilizes the coordinated arrangement of the housing, sliding groove, slider, screen, driving assembly, sliding groove, feeding plate, auxiliary components, shock-absorbing spring, base, discharge pipe, and feed pipe.

[0004] The existing technical solutions mentioned above have the following shortcomings: Although the technical solutions can screen raw materials during use, they cannot screen raw materials of different particle sizes efficiently. Furthermore, the lack of a cleaning mechanism not only easily causes blockage of the screening device but also requires manual cleaning, leaving room for optimization. Therefore, it is necessary to design a raw material screening device for coating processing with a cleaning structure. Utility Model Content

[0005] The purpose of this invention is to provide a raw material screening device for coating processing with a material clearing structure, so as to solve the problems of easy clogging, difficulty in cleaning, and screening of different particle sizes mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material screening device for coating processing with a material clearing structure, comprising a screening box and a feeding hopper, wherein the feeding hopper is fixed at the top of the screening box;

[0007] A fixed base is fixed to the top of the feed hopper. Springs are evenly connected to the top of the inside of the screening box, and a raw material preliminary separation box is fixed to the bottom of the springs. A support plate is fixed to one side of the screening box, and a drive motor is fixed inside the support plate. A first bevel gear is connected to one side of the drive motor, and a second bevel gear is meshed with one side of the first bevel gear. The other end of the second bevel gear is connected to the support plate. A movable groove is opened on one side of the inside of the screening box, and a threaded rod is rotatably connected inside the movable groove. One side of the threaded rod is connected to the output shaft of the drive motor. A threaded sleeve is threaded to the outside of the threaded rod, and a fixed plate is fixed to one side of the threaded sleeve. A belt is connected to the rear end of the second bevel gear. Two sets of electric push rods are fixed to the bottom of the fixed plate, and a cleaning brush is fixed to the bottom of the electric push rod. A primary separation screen is connected below the raw material preliminary separation box.

[0008] Preferably, four springs are provided, and the springs are located at the four corners at the top of the raw material preliminary separation box.

[0009] Preferably, the bottom end of the fixed base is rotatably connected to the feeding auxiliary device, and the top end of the feeding auxiliary device is connected to the output shaft of the rotary motor, and the feeding auxiliary device is spirally downward.

[0010] Preferably, a stacking seat is fixed to one side of the screening box, and a secondary separation screen is fixed to the top of the stacking seat. A raw material conveyor belt runs through the interior of the screening box below the stacking seat. A brush wheel is connected to one side of the belt, and the top of the brush wheel is in contact with the bottom of the raw material conveyor belt.

[0011] Preferably, a first discharge door is hinged to one side of the screening box, and anti-slip sleeves are fixed to the outer side of the first discharge door.

[0012] Preferably, a second discharge door is hinged to one side of the screening box, and the raw material preliminary separation box can be removed through the second discharge door.

[0013] Preferably, the secondary separation net is designed to be inclined toward the side of the raw material conveyor belt, and the bottom of the stacking seat is designed to be inclined toward the side of the first discharge gate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the raw material screening device for coating processing with a material cleaning structure realizes the functions of simultaneous material cleaning and graded screening;

[0017] After a complete screening is completed, the drive motor is started, which drives the threaded rod to rotate. Under the threaded connection between the threaded rod and the threaded sleeve, the fixed plate is moved. The electric push rod is then activated to drive the cleaning brush to clean the surface of the secondary separation screen, preventing clogging. As the electric push rod drives the fixed plate to slide and clean the surface of the secondary separation screen, the first and second bevel gears mesh to drive the brush wheel to rotate via the belt. This synchronously cleans the screened raw material remaining on the surface of the raw material conveyor belt, reducing the time and labor required for manual cleaning, improving work efficiency, and enhancing the practicality and flexibility of the device.

[0018] By starting the vibrating motor, the raw material initial separation box is vibrated up and down, and the raw material on the primary separation screen is screened once. The raw material after primary screening falls onto the secondary separation screen for secondary screening. The qualified raw material falls into the stacking seat, while the unqualified raw material slides onto the raw material conveyor belt through the secondary separation screen and is transported to the outside by the raw material conveyor belt. This achieves the purpose of multi-stage screening of raw materials to facilitate subsequent processing and use. After the entire process is completed, the three sets of screened raw materials of different grades can be taken out through the first discharge gate, the raw material conveyor belt, and the second discharge gate. This not only realizes the functions of grading screening and cleaning, but also enhances the versatility of the device's functions. Attached Figure Description
