Description

Technical Field

[0001] This application relates to the field of coating production technology, and more specifically, to a powder coating ingredient addition device. Background Technology

[0002] With economic development, the requirements for coatings in different fields are increasing. Coatings have been widely used in all corners of society. In China, coatings are traditionally called paint. Coatings are applied to the surface of objects to be protected or decorated, and can form a continuous film that adheres firmly to the object. They are usually made of resin, oil, or emulsion as the main component, with or without pigments and fillers, and with appropriate additives, and are viscous liquids prepared with organic solvents or water. There are many types of coatings. Among them, powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. In the production process of powder coatings, it is necessary to mix and stir various raw materials in proportion.

[0003] In the prior art, a batching box feeding device disclosed in CN218131637U includes a housing, a mixing cylinder fixedly installed inside the housing, the upper end of the mixing cylinder being connected to the top of the housing, a reciprocating component fixedly installed on the upper surface of the housing, a feeding pipe fixedly installed inside the reciprocating component, a valve body fixedly installed inside the feeding pipe, a measuring hopper fixedly installed at the upper end of the feeding pipe, and a rotating shaft rotatably connected to the bottom of the housing. The upper end of the rotating shaft extends through the mixing cylinder and is fixedly installed with a stirring screw. This batching box feeding device can quantitatively feed materials and can disperse the added raw materials. However, its structure is complex, and its material dispersion effect is poor, resulting in low material mixing efficiency. Therefore, there is an urgent need for a powder coating batching and adding device with a simple structure and better material dispersion effect. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a powder coating ingredient addition device, wherein the cylinder of the filling mechanism drives the moving block to move, wherein the moving block has a certain capacity, and the moving block moves back and forth under the drive of the cylinder, falling into the material distribution plate through the first through hole. The material distribution plate intercepts and disperses the powder coating, resulting in better dispersion effect. The device has a simple structure and is suitable for promotion.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A powder coating ingredient addition device includes a mixing tank, a stirring mechanism, a filling mechanism, and a distributing tray. The mixing tank is a hollow cylindrical structure. The stirring mechanism includes a rotary motor, a stirring shaft, and a stirring rod. The rotary motor is fixed to the bottom of the mixing tank, and its output shaft is fixedly connected to the stirring shaft. The stirring rod is arranged around the stirring shaft. The filling mechanism includes a box body, a moving block, a cylinder, and a material box. The box body is fixedly connected to the inner wall of the mixing tank via a rod. The bottom of the box body has a first through hole, and the top of the box body has a material inlet. The box body is a hollow cuboid structure. The moving block is slidably disposed inside the box body and has a second through hole. The material box is fixed above the box body. The cylinder is fixedly connected to the outer wall of the mixing tank, and its output shaft is fixedly connected to the moving block. The distributing tray is a disc-shaped structure, fixed above the stirring shaft, and located below the box body. The distributing tray has several gaps.

[0007] Preferably, the bulk material tray includes an outer tray and an inner tray, and the outer tray has a certain tilt angle.

[0008] Preferably, the tilt angle of the outer disc is 10-20°.

[0009] Preferably, the bottom center of the inner disc is fixedly connected to the top of the stirring shaft, and the inner disc is also provided with several discharge holes.

[0010] Preferably, the length of the moving block is less than the length of the box body.

[0011] Preferably, there are two first through holes and two second through holes.

[0012] Preferably, a certain distance is left between the first through holes.

[0013] Preferably, the bottom of the mixing tank is provided with a discharge port, and the discharge port is provided with a cover.

[0014] Preferably, the ingredient container is provided with a top cover, and the top cover is provided with a handle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes a filling mechanism to quantitatively dispose of powdered materials. The material inlet at the top of the box allows material to enter the box. As the cylinder drives the moving block, the powder enters the second through-hole of the moving block. The material inlet and the first through-hole are staggered. Driven by the cylinder, the moving block moves back and forth, and the material falls through the first through-hole into a distribution tray. The distribution tray intercepts the powder coating. The distribution tray rotates during the rotation of the rotary motor, causing some of the powder coating to fall through the gaps. The remaining powder is blocked by the outer disc and falls through the discharge hole and gaps, resulting in better dispersion. The mixing effect is further enhanced by the stirring rod.

The material inlet 11 enters the second through hole 12. The cylinder 7 is fixedly connected to the outer wall of the mixing tank 1. The output shaft of the cylinder 7 is fixedly connected to the moving block 6. The output shaft of the cylinder 7 is slidably disposed with the box body 5. The cylinder 7 is used to drive the moving block 6 to move left and right within the box body 5. When the moving block 6 moves, the second through hole 12 and the first through hole 10 gradually become connected. The powder coating in the second through hole 12 falls down. Furthermore, the material inlet 11 and the first through hole 10 are staggered. The material distribution tray 19 has a disc-shaped structure. The material distribution tray 19 is fixed to... Above the stirring shaft 3, the material tray 19 is located below the box body 5. The material tray 19 has several gaps 13. The material falls into the material tray 19 through the first through hole 10. The material tray 19 intercepts the powder coating.
