DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A low-dust powder screening device for cosmetic production includes a screening machine body 1, a feed hopper 2, and a dust hood 9, wherein the screening machine body 1 is a prior art product, and its specific structure and working principle are not described in detail in this scheme. A dust suction pipe 10 is installed on the dust hood 9, and a negative pressure pump is connected to the end of the dust suction pipe 10. The negative pressure pump is also connected to a dust outlet pipe, and a dust bag is installed on the dust outlet pipe to realize the dust collection operation. The above-mentioned negative pressure pump and dust outlet pipe are not drawn in this scheme, and the equipment components of the prior art can be referred to.

[0021] A support frame 4 is provided on the upper end surface of the screening machine body 1 through a support rod 3. A stirring shaft 6 located in the feed hopper 2 is rotatably provided on the bottom wall of the support frame 4. A power mechanism connected to the stirring shaft 6 is provided on the support frame 4. A plurality of stirring rods 17 are provided on the outer wall of the stirring shaft 6. The feed hopper 2 is thick at the top and thin at the bottom. The stirring rods 17 are arranged correspondingly thereto, and their lengths decrease from top to bottom. The feed hopper 2 is sealed to prevent dust from leaking out. A feed port is also provided thereon, and a sealing plug is provided in the feed port. With the help of the sealing plug and the feed hopper 2, the cosmetic powder to be screened can be conveniently put in.

[0022] The dust hood 9 is installed on the screening machine body 1 through a fixing mechanism. A circular opening corresponding to the dust hood 9 is provided on the upper end surface of the screening machine body 1. A rotating ring 12 is provided between the circular opening and the dust hood 9. A protective net 15 is installed on the dust hood 9. A transmission shaft 7 is provided on the upper end surface of the screening machine body 1. The transmission shaft 7 is connected to the stirring shaft 6 through a rotating mechanism, and the transmission shaft 7 is connected to the rotating ring 12 through a transmission mechanism.

[0023] The power mechanism includes a stirring motor 5 arranged on a support frame 4, and the output shaft of the stirring motor 5 is fixedly connected to the end of the stirring shaft 6. As shown in the figure, the support frame 4 is U-shaped, and the stirring motor 5 is arranged on it to provide power to the stirring shaft 6, which can drive the stirring shaft 6 to rotate.

[0024] The fixing mechanism includes a fixing frame 11 fixedly connected to the dust hood 9. The fixing frame 11 is L-shaped and connected to the screening machine body 1 by means of a bolt assembly. The fixing frame 11 realizes the fixed placement of the dust hood 9 in the circular opening. The dust hood 9 is circular, and there is a gap between it and the inner wall of the circular opening and it is annular.

[0025] The rotating mechanism includes a driving pulley 8 connected to the stirring shaft 6 and the transmission shaft 7. The two driving pulleys 8 are connected by a connecting belt, and the power transmission of the stirring motor 5 is achieved by means of the driving pulley 8 and the connecting belt.

[0026] The transmission mechanism includes a gear 14 arranged on the transmission shaft 7, and a ring gear 13 meshing with the gear 14 is provided on the rotating ring 12. The power transmission of the stirring motor 5 is realized by means of the gear 14 and the ring gear 13, and the synchronous rotation of the rotating ring 12 can be realized after the stirring motor 5 is started.

[0027] The vertical section of the rotating ring 12 is L-shaped, and the rotating ring 12 is sealed and slidably connected to the circular opening and the dust cover 9, and the sealed and slidably connected ensures the sealing performance.

[0028] When the utility model is used, the cosmetic dust material is put into the feed hopper 2, and then the stirring motor 5 is started. The stirring motor 5 can drive the stirring shaft 6 to rotate, and the rotation of the stirring shaft 6 drives the stirring rod 17 to rotate. The stirring rod 17 realizes the stirring treatment of the cosmetic dust material and breaks up the condensed part thereof. Then, the valve assembly in the discharge pipe of the feed hopper 2 is opened, and the above-mentioned material enters the interior of the screening machine body 1 for screening treatment. At this time, the stirring motor 5 does not stop, so that the stirring shaft 6 and the stirring rod 17 continue to rotate to stir and break up the gradually reduced material. Therefore, at this time, the transmission shaft 7 can be driven to rotate by means of the transmission pulley 8 and the connecting belt. When the transmission shaft 7 rotates, the gear 14 can be driven to rotate by the gear ring 13. The rotating ring 12 can drive the scraper 16 to rotate to realize the cleaning operation of the surface of the protective net 15 to avoid the clogging of its mesh. At this time, the dust hood 9 is driven by the negative pressure pump assembly to be in a working state, and its pressure is not too large, so the internal dust can be sucked away to avoid excessive leakage from the screening machine body 1 to affect the workshop.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
