Description

Technical Field

[0001] This invention relates to the field of grinding technology, specifically to a waterproof eyeshadow powder grinding device. Background Technology

[0002] Eyeshadow powder grinding refers to the process of refining eyeshadow raw materials through grinding equipment to achieve certain particle size and texture requirements. This helps improve the fineness, gloss, adhesion, and spreadability of eyeshadow powder. There are also different grinding methods, such as disc grinding.

[0003] The invention disclosed in publication number CN108355768 A is a grinding device for processing cosmetic raw materials. By setting a load-bearing horizontal plate, when the drive motor starts and the grinding rod drives the grinding disc to rotate, the servo motor starts the gears to rotate. The gears mesh with the load-bearing horizontal plate, causing the load-bearing horizontal plate to move from both sides towards the center. This allows the load-bearing horizontal plate to support the raw materials on the filter screen, facilitating grinding. After grinding is completed, the load-bearing horizontal plate moves to both sides, and the raw materials on the filter screen flow from the grinding table to the discharge hopper. The filter screen filters the ground raw materials, ensuring that the discharged raw materials have a uniform particle size. It is more convenient to use, eliminating the need for secondary processing and saving time. However, this solution, through the cooperation of the grinding disc and the load-bearing horizontal plate, completes the grinding of raw materials. However, when finely grinding eyeshadow raw materials, it cannot effectively and quickly obtain the required fineness of eyeshadow powder, which is time-consuming, labor-intensive, and inconvenient to use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figures 1-13 This application provides the following technical solutions.

[0036] Example 1: A waterproof eyeshadow powder grinding device includes a main control support box 1. A grinding box 2 is vertically mounted on one side of the upper end of the main control support box 1. A grinding motor 3 is vertically mounted at the center of the upper end of the grinding box 2. A drive shaft 5 is mounted at the lower end of the grinding motor 3. The lower end of the drive shaft 5 is placed inside the grinding box 2 and has a grinding rotating table 6. A mating grinding ring 4 is fixed inside the grinding box 2 by bolts. The grinding rotating table 6 is arranged correspondingly to the mating grinding ring 4 by multiple grinding components. The multiple grinding components include a conical grinding disc 7, a cylindrical grinding disc 12, and several grinding wheels 11. The conical grinding disc 7 is fixedly sleeved on the upper outer circumferential surface of the grinding rotating table 6 by bolts. A mounting boss is inclined downward in the middle of the outer circumferential surface of the grinding rotating table 6. A conical wheel groove 10 is inclinedly opened at the lower end of the mounting boss. Several grinding wheels 11 are respectively rotatably mounted in the conical wheel groove 10 by a rotating shaft. The cylindrical grinding disc 12 is fixed to the lower outer circumference of the grinding rotating table 6 by bolts. The upper end of the grinding ring 4 is provided with a gradient conical groove 8. The outer circumference of the conical grinding disc 7 is correspondingly set with the inner side of the gradient conical groove 8. The middle part of the grinding ring 4 is provided with a grinding groove 9. One side of several grinding wheels 11 extends out of the conical wheel groove 10 and is inserted into the grinding groove 9. The outer circumference of the cylindrical grinding disc 12 is correspondingly set with the lower end of the inner circumference of the grinding ring 4. When grinding the raw materials for waterproof eyeshadow, the material is sent from the top of the grinding box 2 into the position of the gradient conical groove 8. The conical grinding disc 7 performs the first grinding. After grinding, the powder falls into the grinding groove 9 and is kneaded and ground a second time by several grinding grooves 9. After the second grinding, the powder falls naturally from the lower inclined surface of the grinding groove 9 and is ground a third time through the inner wall of the cylindrical grinding disc 12 and the grinding ring 4.

[0037] An enhanced processing component is used to further refine the fineness of the eyeshadow powder after three rounds of mechanical grinding. This component includes a collection and sealing disc 17 and several conical enhanced grinding grooves 32. The collection and sealing disc 17 is positioned below the grinding rotary table 6 within the grinding chamber 2 via a rotating support assembly. The conical enhanced grinding grooves 32 are located within the grinding rotary table 6. The rotating support assembly includes a support tray 13 and a rotation control box 14. A flow-guiding collection groove 31 is located at the upper end of the grinding rotary table 6, and a concave groove 30 is located at the lower end. Several conical enhanced grinding grooves 32 are connected between the concave groove 30 and the flow-guiding collection groove 31. The diameter of one side of the conical enhanced grinding groove 32 connected to the flow-guiding collection groove 31 is smaller than the diameter of the other side. The inner diameter of the conical enhanced grinding groove 32 is... The wall is provided with several shearing and grinding rods 35. The two downward sides of the flow collection groove 31 are both conical. A central discharge groove is opened in the center of the grinding rotary table 6. The flow collection groove 31 is provided with annular screw grooves on the side near the conical reinforcing grinding groove 32. The flow collection groove 31 is covered with a filter screen 34 on the side of the conical reinforcing grinding groove 32. A clamping screw ring 33 is threaded into the annular screw groove. The side of the filter screen 34 is inserted into the annular screw groove and clamped by the clamping screw ring 33. The upper side of the filter screen 34 in the annular screw groove is in contact with the lower side of the clamping screw ring 33. The powder after being ground by the grinding ring 4 and the cylindrical grinding disc 12 will be located below the concave disc groove 30, waiting to be blown into the conical reinforcing grinding groove 32.

[0038] The lower end of the grinding ring 4 is provided with an annular retaining groove 29, and the upper end of the collecting and sealing disc 17 is provided with a powder receiving inner conical groove 23. An annular sealing plate is provided around the powder receiving inner conical groove 23 at the upper end of the collecting and sealing disc 17. The annular sealing plate is inserted into the annular retaining groove 29. Several annular sealing pieces are provided between the inner circumference of the annular sealing plate and the annular retaining groove 29. When the annular sealing plate is inserted into the uppermost part of the annular retaining groove 29, the lower end of the cylindrical grinding disc 12 abuts against the inclined surface of the powder receiving inner conical groove 23. During normal grinding, the powder passing through the grinding ring 4 and the cylindrical grinding disc 12 falls into the powder receiving inner conical groove 23. When the cylindrical grinding disc 12 abuts against the inclined surface of the powder receiving inner conical groove 23 of the collecting and sealing disc 17, the collecting and sealing disc 17 and the inner concave disc groove 30 form an independent chamber. At this time, the powder will not fall between the cylindrical grinding disc 12 and the grinding ring 4, and continuous grinding can be carried out. At the same time, the independent chamber formed by the powder receiving inner conical groove 23 and the inner concave disc groove 30 facilitates subsequent operation.

[0039] The support tray 13 is horizontally fixed to the lower end of the grinding chamber 2 by bolts. The rotation control box 14 is rotatably positioned at the center of the support tray 13 via two sealed bearings. A piston chamber is opened at the upper end of the rotation control box 14. A prismatic guide groove 16 is opened through the upper end of the piston chamber. A prismatic sealing sleeve 18 is provided at the lower center of the collecting sealing plate 17. The prismatic sealing sleeve 18 passes through the prismatic guide groove 16 and is inserted into the piston chamber. A lifting piston 19 is provided at the lower end of the prismatic sealing sleeve 18 in the piston chamber. A return spring 20 is sleeved above the lifting piston 19 in the piston chamber. An extended discharge pipe 15 is provided at the center of the grinding rotary table 6 located in the concave groove 30 and connected to the center discharge groove. The discharge pipe 15 passes through the center of the rotation control box 14. The rotation control box 14 is fixedly connected to the extended discharge pipe 15 by a sealing ring and bolts. The collection sealing plate 17 and the prismatic sealing sleeve 18 are connected to the extended discharge pipe 15 by an annular piston plate. The extended discharge pipe 15 is fixed or integrally set with the grinding rotation table 6. The drive shaft 5 is fixed or integrally set with the grinding rotation table 6. After the rotation control box 14 is fixed to the extended discharge pipe 15 by bolts, the rotation of the grinding rotation table 6 can drive the rotation control box 14 and the collection sealing plate 17 to rotate synchronously. After the collection sealing plate 17 abuts against the cylindrical grinding disc 12 through the powder receiving inner conical groove 23, the two remain relatively stationary and are in a synchronous motion posture.

[0040] A first annular connecting air groove 24 is provided on the support tray 13 near the rotation control box 14 and between two sealed bearings. The lower end of the first annular connecting air groove 24 passes through the support tray 13 and is provided with an air inlet. A second annular connecting air groove 25 is provided on the outer periphery of the rotation control box 14 near the first annular connecting air groove 24. The upper end of the second annular connecting air groove 25 is provided with several connecting holes and is connected to the piston chamber. An annular raft plate 21 is provided on the lower end of the lifting piston 19 and is connected to the extended discharge pipe 15. A diversion groove 26 is provided in the collection sealing plate 17. Several first connecting grooves 27 are provided in the annular raft plate 21 and are connected to the diversion groove 26. A one-way valve is inserted into the lower end of each of the several first connecting grooves 27. 22. Several grinding air holes 28 are provided on one side of the inclined surface of the powder receiving inner cone groove 23 in the diversion groove 26. When the lower end of the cylindrical grinding disc 12 abuts against the inclined surface of the powder receiving inner cone groove 23, the grinding air holes 28 are connected to the inner concave disc groove 30 and the conical reinforcing grinding groove 32 through the powder receiving inner cone groove 23. The length of the annular sealing plate inserted into the annular retaining groove 29 is greater than the vertical movement length of the collecting sealing disc 17 and the prismatic sealing sleeve 18. When high-pressure gas is introduced into the air inlet of the first annular connecting air groove 24, the high-pressure gas can push the lifting piston 19, the prismatic sealing sleeve 18 and the collecting sealing disc 17 to rise, so as to realize the independent chamber composition of the powder receiving inner cone groove 23 and the inner concave disc groove 30.

[0041] In this embodiment: the eyeshadow raw material entering the grinding chamber 2 is ground by the conical grinding disc 7, grinding wheel 11, cylindrical grinding disc 12, and mating grinding ring 4 to achieve a sufficiently fine powder. At this time, the powder falls from between the mating grinding ring 4 and the cylindrical grinding disc 12 into the powder receiving conical groove 23 of the collecting and sealing disc 17. After processing for a certain period of time, high-pressure gas is introduced into the first annular connecting gas groove 24. The high-pressure gas enters the piston chamber and pushes the lifting piston 19 and the collecting and sealing disc 17 to rise. The bottom of the cylindrical grinding disc 12 abuts against the inclined surface of the powder receiving conical groove 23. The powder receiving conical groove 23 and the concave disc groove 30 form an independent chamber. At this time, the gas pressure continues to rise. The high-pressure gas pushes several one-way valves 22 and enters the diversion groove 26 through the first connecting groove 27. Then, high-pressure gas is blown from several grinding air holes 28 to the powder accumulated at the bottom of the powder receiving inner cone groove 23. At this time, the airflow in the grinding rotary table 6 can only be discharged through the central exhaust groove and the extended discharge pipe 15 connected by the flow collection groove 31. The powder in the powder receiving inner cone groove 23 is passively lifted. When passing through the cone-shaped reinforced grinding groove 32, it is collided and sheared by several irregularly set shearing grinding rods 35 inside, and further ground. Particles with the required particle size continue to rise and pass through the filter screen 34, and enter the flow collection groove 31. Then, under the guidance of the airflow in the flow collection groove 31, it is discharged from the central discharge groove and the extended discharge pipe 15. The airflow and powder discharged from the extended discharge pipe 15 can be centrally separated and ground by a filter bag or a cyclone separator.

[0042] Example 2: Based on Example 1, a rotation auxiliary component is provided to assist the rotational power of the grinding motor 3. The rotation auxiliary component is located inside the drive shaft 5 and includes a central air groove 39 and several auxiliary rotation air grooves 40. An annular retaining groove 29 is opened in the center of the drive shaft 5, and the lower end of the annular retaining groove 29 is connected to the upper center of the guide collection groove 31. A central connecting pipe 38 is vertically provided in the center of the central discharge groove of the grinding rotary table 6. The upper end of the central connecting pipe 38 is inserted into the lower end of the central air groove 39 through a sealing gasket. An annular collecting groove 37 is opened on the side of the grinding rotary table 6 near the central connecting pipe 38. The lower end of the central connecting pipe 38 is fixedly connected to the inner side wall of the central discharge groove. The central connecting pipe 38 is connected to the annular collecting groove 37, and the lower end of the annular collecting groove 37 is connected to the rotation control. The piston chamber of box 14 is provided with several second connecting slots 36. When the lifting piston 19 and the collecting sealing plate 17 rise to the maximum extent, the second connecting slots 36 disengage from the sealing of the annular raft plate 21 and connect with the piston chamber. An auxiliary air slot is provided at the upper end of the central air slot 39 inside the drive shaft 5. Several auxiliary rotating air slots 40 are connected to the auxiliary air slots respectively. Several auxiliary rotating air slots 40 pass through the drive shaft 5 along the tangent of the inner side wall of the auxiliary air slots. A guide shell 41 is sleeved on the drive shaft 5 above the grinding table 6. Several auxiliary rotating air slots 40 are exposed above the guide shell 41. When the grinding motor 3 is performing grinding operations, in order to reduce energy consumption, the grinding motor 3 can be powered off after the speed reaches the required level and continues for a certain period of time. At this time, the drive shaft 5 and the grinding table 6 continue to rotate and grind under the action of inertia.

[0043] The timing of the power outage can be coordinated with the powder collection status in the powder receiving conical groove 23 of the collecting and sealing disc 17. When the collecting and sealing disc 17 needs to rise and use high-pressure airflow to achieve powder conveying and grinding, the drive shaft 5 loses power to the grinding motor 3. High-pressure gas is blown out at high speed from several auxiliary rotating air grooves 40. The high-speed airflow can assist in the rotation of the drive shaft 5. In conjunction with the power on and off of the grinding motor 3, the grinding motor 3 can achieve high efficiency and energy saving. In addition, the auxiliary rotating air grooves 40 are located at a high position on the drive shaft 5. When the gas is blown out, it will not affect the eyeshadow raw materials in the grinding box 2. At the same time, the high-speed airflow can accelerate the airflow around the grinding motor 3, improve the cooling effect of the grinding motor 3, and play a positive role in further energy saving of the grinding motor 3.

[0044] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
