Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a raw material screening device for real stone paint. Background Art

[0002] Real stone paint is a type of paint that creates a decorative effect resembling marble and granite. It's primarily formulated with natural stone powders of various colors. It's used on building exteriors to create a stone-like effect, hence the name "liquid stone." Natural stone powder, the primary raw material for real stone paint, is typically made from various natural stones that have been crushed, ground, and screened.

[0003] Among the screening devices currently used, there is a screening device for processing real stone paint disclosed in patent CN219785526U. When working, the vibration motor inside the engine box vibrates to vibrate and screen the raw materials on the screen. Then, the pull block can be pulled to drive the baffle to be pulled out on the discharge barrel to facilitate the discharge of the raw materials; at the same time, the screen can be pulled to drive the pulley to slide and be pulled out on the slide rail through the transmission frame, and the unqualified raw materials can be taken out in a centralized manner.

[0004] However, the material taking process of this screening device is relatively complicated, and it is inconvenient to adjust and control the screening size of the stone, which cannot meet the screening needs of different situations. Its practicality is general, and therefore needs to be improved. Utility Model Content

[0005] In order to solve the above technical problems, the utility model discloses a raw material screening device for real stone paint, including a bracket, a screening auger, a drive motor, an upper cover body, a lower cover body, a feed hopper and a discharge port.

[0006] Furthermore, the upper cover body and the lower cover body are both semicircular structures, the upper side of the lower cover body partially overlaps with the lower side of the upper cover body, and the inner diameter of the lower cover body is equal to the outer diameter of the upper cover body.

[0007] Furthermore, the upper cover body is provided with a positioning column at one end and a first threaded portion at the other end, the lower cover body is provided with a slot at one end and a second threaded portion at the other end, the positioning column is clamped in the slot, and the first threaded portion and the second threaded portion are both semicircular structures with the same radius.

[0008] Furthermore, the discharge port is connected to the outside of the complete annular thread consisting of the first thread portion and the second thread portion in a threaded manner.

[0009] Furthermore, the screening auger is a conical structure, and the outer diameter of the side close to the feed hopper is smaller than the outer diameter of the side close to the discharge port, and the pitch of the side close to the feed hopper is greater than the pitch of the side close to the discharge port.

[0010] Furthermore, a material receiving box is provided on the bracket below the lower cover body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The raw material screening device of the present invention drives the screening auger to rotate through a driving motor, and sends the materials located inside the upper cover and the lower cover to the discharge port, wherein smaller powdery or granular materials are discharged through the sieve holes on the lower cover, and larger materials are discharged through the discharge port. The lower cover can be replaced with sieve holes of different apertures to meet the screening needs of materials of different sizes, thereby improving the practicality of the screening device.
