Technical Field
[0001] This utility model relates to the field of cosmetic production technology, specifically to a cosmetic powder screening device. Background Technology
[0002] Cosmetic powder raw materials are mainly used in powdered cosmetics, such as talcum powder, face powder, pressed powder, lipstick, blush, and eyeshadow. In cosmetics, they primarily function to cover, smooth, adhere, absorb, and spread. Commonly used raw materials in cosmetics include inorganic powder raw materials, organic powder raw materials, and other powder raw materials. Cosmetic powder raw materials are made from large solid raw materials through processes such as crushing and grinding. After these processes, the powder raw materials usually need to be sieved.
[0003] In existing technologies, cosmetic powders are typically sieved by conveying them into a sieve frame. However, in actual use, the powder tends to accumulate in one place when it is fed, affecting the uniformity of the powder distribution on the sieve frame. This results in a longer screening time and reduces the screening efficiency. Therefore, a cosmetic powder screening device is proposed. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1:
[0029] Please refer to the following: Figures 1-5This utility model provides a technical solution: a cosmetic powder screening device, including a screening box 100, a feeding component 200, and a driving component. The feeding component 200 is located above the screening box 100 and is used to feed the powder. The driving component is located above the screening box 100 and is used to drive the feeding component 200 to move, so that the feeding component 200 evenly distributes and conveys the powder into the screening box 100. Specifically, the powder is fed into the feeding component 200, and the feeding component 200 conveys the powder into the screening box 100. The driving component drives the feeding component 200 to move, so that the feeding component 200 evenly distributes and conveys the powder into the screening box 100.
[0030] Furthermore, the feeding assembly 200 includes a feeding cylinder 201, the bottom of which is connected to a distributing cylinder 202. A distributing disc 204 is rotatably connected inside the distributing cylinder 202. A first motor 203 is mounted on the outer surface of the distributing cylinder 202. The output end of the first motor 203 is fixedly connected to the distributing disc 204. A plurality of distributing slots 205 arranged in a circumferential array are opened on the outer surface of the distributing disc 204. A feeding pipe is connected to the bottom of the distributing cylinder 202. One end of the feeding pipe extends into the interior of the screening box 100. Specifically, the cosmetic powder to be screened is conveyed into the feeding cylinder 201. The first motor 203 drives the distributing disc 204 to rotate, so that the cosmetic powder enters the distributing slots 205 in the distributing disc 204. When the distributing slots 205 correspond to the distributing pipe, the distributing material in the distributing slots 205 falls into the interior of the screening box 100 through the distributing pipe, so that the cosmetic powder enters the interior of the screening box 100 intermittently.
[0031] Furthermore, the drive assembly includes two sets of fixed blocks arranged symmetrically from left to right. Each set consists of two fixed blocks arranged symmetrically from front to back. All four fixed blocks are positioned above the screening box 100. A reciprocating screw 500 is rotatably connected between the two fixed blocks in one set. A second motor 501 is mounted on the outer surface of one of the fixed blocks. The output end of the second motor 501 is fixedly connected to the reciprocating screw 500. L-shaped plates 502 are fixedly connected to both sides of the distributing cylinder 202. One of the L-shaped plates 502 is threadedly connected to the outer surface of the reciprocating screw 500. Specifically, the second motor 501 drives the reciprocating screw 500 to rotate, causing the reciprocating screw 500 to move the L-shaped plate 502. The L-shaped plate 502 then moves the feeding assembly 200, allowing the feeding assembly 200 to evenly convey the powder into the screening box 100, thereby improving the subsequent screening efficiency.
[0032] Furthermore, the screening box 100 is equipped with a dual filtration assembly inside, which is used to perform dual filtration of the powder.
[0033] Furthermore, the dual filtration assembly includes a first screening plate 300 and a second screening plate 301. Both the first screening plate 300 and the second screening plate 301 are inclined and fixed to the right inner wall and the left inner wall of the screening box 100, respectively. The first screening plate 300 is located above the second screening plate 301. Specifically, when the powder enters the screening box 100, the powder falls onto the inclined first screening plate 300 and moves on the inclined first screening plate 300. The powder is screened by the first screening plate 300. The powder that is not screened falls onto the first screening plate 300 and then falls onto the second screening plate 301 for secondary screening.
[0034] Furthermore, the screening box 100 is equipped with two guide plates 302, which are located below the first screening plate 300 and the second screening plate 301 respectively. The screening box 100 has discharge ports on both the left and right sides, and each discharge port is equipped with a receiving frame 303. Specifically, the powder that has been screened by the first screening plate 300 and the second screening plate 301 falls onto the guide plate 302 and enters the receiving frame 303.
[0035] Furthermore, a receiving drawer 304 is movably inserted inside the receiving frame 303, and one end of the guide plate 302 extends above the receiving drawer 304. Specifically, the powder that has been screened by the first screening plate 300 and the second screening plate 301 falls onto the guide plate 302 and is guided by the guide plate 302 into the receiving drawer 304 for collection.
[0036] Furthermore, the screening box 100 is equipped with a receiving box 400, which is located below the second screening plate 301. Specifically, powder that has not been screened by the second screening plate 301 falls into the receiving box 400 for collection.
[0037] Furthermore, each of the four corners of the bottom of the receiving box 400 is equipped with a movable wheel 401, and the bottom inner wall of the screening box 100 has two sliding grooves. The movable wheel 401 is slidably connected to the inside of the sliding grooves. Specifically, when the receiving box 400 is pulled out and placed in the screening box 100, the movable wheel 401 slides inside the sliding grooves, thereby facilitating the movement of the receiving box 400.
[0038] Furthermore, a sliding rod is fixedly connected between two fixed blocks in another set, and another L-shaped plate 502 is movably sleeved on the outside of the sliding rod. A moving groove is opened on the top outer surface of the screening box 100, and the feeding pipe is slidably connected to the inside of the moving groove. Specifically, when the reciprocating screw 500 rotates and drives the L-shaped plate 502 on it to move, causing the distributing cylinder 202 to move, the other L-shaped plate 502 slides outside the sliding rod. The sliding rod guides the movement of the L-shaped plate 502, so that the distributing cylinder 202 moves stably in a straight line, and the feeding pipe moves inside the moving groove. The moving groove provides space for the movement of the feeding pipe.
[0039] Working Principle: In use, the cosmetic powder to be screened is conveyed into the feeding cylinder 201. The first motor 203 drives the distributing plate 204 to rotate, causing the cosmetic powder to enter the distributing groove 205 within the distributing plate 204. When the distributing groove 205 aligns with the feeding pipe, the powder in the distributing groove 205 falls into the screening box 100 through the feeding pipe, thus allowing the cosmetic powder to enter the screening box 100 intermittently. The second motor 501 then drives the reciprocating screw 500 to rotate, causing the reciprocating screw 500 to move the L-shaped plate 502. The L-shaped plate 502 then moves the feeding assembly 200, ensuring that the feeding assembly 200 evenly conveys the powder into the screening box 100, thereby improving the subsequent screening efficiency.
[0040] When the powder enters the screening box 100, it falls onto the inclined first screening plate 300. The powder moves on the inclined first screening plate 300 and is screened by the first screening plate 300. The powder that is not screened falls onto the first screening plate 300 and then onto the second screening plate 301 for secondary screening. The powder that has been screened by the first screening plate 300 and the second screening plate 301 falls onto the guide plate 302 and is guided by the guide plate 302 into the receiving drawer 304 for collection. The powder that has not been screened by the second screening plate 301 falls into the receiving box 400 for collection.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
