Description

Technical Field

[0001] This utility model relates to the field of cosmetic production technology, and in particular to a raw material grinding and extraction machine. Background Technology

[0002] Cosmetics are chemical mixtures made from various natural, synthetic, or extracted substances with different functions as raw materials, processed through production processes such as heating, stirring, and emulsification. When adding natural minerals, they need to be ground.

[0003] Currently, the most commonly used cosmetic grinding and extraction machine is the three-roll mill. This type of mill uses three grinding rollers with different rotation speeds to compress and grind materials. A scraper and collection hopper at the tail end collect the ground material. If multiple grinding cycles are required, the collected material is added back to the mill head for further grinding. However, for cosmetic raw materials requiring multiple grinding cycles, workers must continuously collect the material from the tail end and add it back to the mill head for re-grinding, which undoubtedly increases labor intensity. Therefore, to address these shortcomings, this invention proposes a raw material grinding and extraction machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw material grinding and extraction machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a raw material grinding and extraction machine, comprising a casing, a grinding assembly inside the casing, three first motors for driving the grinding assembly fixed on the outer wall of the casing, two baffles fixed inside the casing and above the grinding assembly, the grinding assembly including three horizontal shafts rotatably connected to the inner wall of the casing via bearings, a first grinding roller, a second grinding roller and a third grinding roller respectively fixed on the surfaces of the three horizontal shafts, the second grinding roller being located between the first grinding roller and the third grinding roller, a scraping assembly inside the casing and below the third grinding roller, an inclined tube fixedly connected to the bottom end of the scraping assembly, a vertical tube fixed inside the casing near the first grinding roller, the inclined tube communicating with the bottom of the vertical tube, a conveying assembly inside the vertical tube, a second motor for driving the conveying assembly to rotate installed at the top of the vertical tube, an inclined discharge pipe fixed to the top side wall of the vertical tube, the other end of the discharge pipe extending between the first grinding roller and the second grinding roller, and an opening near the vertical tube at the bottom end of the casing.

[0006] Furthermore, the three drive ends of the first motor are respectively fixedly connected to the three horizontal shafts. The first grinding roller and the third grinding roller rotate in the same direction, and the first grinding roller and the third grinding roller rotate in the opposite direction to the second grinding roller.

[0007] Furthermore, each of the two baffles has three arc-shaped grooves at its bottom, and the three arc-shaped grooves are respectively engaged with the surfaces of the first grinding roller, the second grinding roller, and the third grinding roller.

[0008] Furthermore, the scraping assembly includes a hopper, the top of the inclined tube is connected to the bottom of the hopper, a scraper is fixed at the top of the hopper and near the second grinding roller, and the top of the scraper is in contact with the lower surface of the third grinding roller.

[0009] Furthermore, the top of the hopper and both sides of the scraper are fixedly connected to side plates, and the top of the side plates is arc-shaped, with the top of the side plates fitting against the lower surface of the third grinding roller.

[0010] Furthermore, the conveying assembly includes a flexible auger located inside the vertical tube, a connecting shaft fixed to the top of the flexible auger, a through hole at the top of the vertical tube, a bracket connected to the second motor and the upper surface of the vertical tube, and the top of the connecting shaft passing through the through hole and being fixedly connected to the output shaft of the second motor by bolts.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a raw material grinding and extraction machine is disclosed, comprising a housing 1, a grinding assembly 2 disposed inside the housing 1, three first motors 3 for driving the grinding assembly 2 fixed to the outer wall of the housing 1, and two baffles 4 fixed inside the housing 1 and above the grinding assembly 2. The grinding assembly 2 includes three horizontal shafts 21 rotatably connected to the inner wall of the housing 1 via bearings. A first grinding roller 22, a second grinding roller 23, and a third grinding roller 24 are respectively fixed to the surfaces of the three horizontal shafts 21, with the second grinding roller 23 located between the first grinding roller 22 and the third grinding roller 24. Inside the machine housing 1 and below the third grinding roller 24, there is a scraping assembly 5. The bottom end of the scraping assembly 5 is fixedly connected to an inclined tube 6. Inside the machine housing 1 and near the first grinding roller 22, there is a vertical tube 7. The inclined tube 6 is connected to the bottom of the vertical tube 7. Inside the vertical tube 7, there is a conveying assembly 8. The top of the vertical tube 7 is equipped with a second motor 9 that drives the conveying assembly 8 to rotate. An inclined discharge pipe 11 is fixed to the top side wall of the vertical tube 7. The other end of the discharge pipe 11 extends between the first grinding roller 22 and the second grinding roller 23. A notch 101 is opened at the bottom end of the machine housing 1 near the vertical tube 7.

[0024] The drive ends of the three first motors 3 are fixedly connected to the three horizontal shafts 21 respectively. The first grinding roller 22 and the third grinding roller 24 rotate in the same direction, and the first grinding roller 22 and the third grinding roller 24 rotate in the opposite direction to the second grinding roller 23.

[0025] In this embodiment, the three grinding rollers rotate at different speeds. When the three first motors 3 drive the three grinding rollers to rotate, the material can be ground by friction and extrusion. The principle here is the same as that of existing grinding machines.

[0026] Both baffles 4 have three arc-shaped grooves at their bottoms, and the three arc-shaped grooves are respectively engaged with the surfaces of the first grinding roller 22, the second grinding roller 23 and the third grinding roller 24.

[0027] Baffle 4 can block the material located on the surface of the three grinding rollers and limit the width of grinding.

[0028] The scraping assembly 5 includes a hopper 51, the top of the inclined tube 6 is connected to the bottom of the hopper 51, and a scraper 52 is fixed at the top of the hopper 51 and near the second grinding roller 23. The top of the scraper 52 is in contact with the lower surface of the third grinding roller 24.

[0029] When the third grinding roller 24 rotates, the scraper 52 can scrape the material on the surface of the third grinding roller 24 into the hopper 51. The material entering the hopper 51 will enter the vertical pipe 7 along the inclined pipe 6.

[0030] Side plates 53 are fixedly connected to the top of the hopper 51 and on both sides of the scraper 52. The top of the side plates 53 is arc-shaped and fits against the lower surface of the third grinding roller 24.

[0031] The side plate 53 can prevent scraped material from scattering outside the hopper 51.

[0032] The conveying assembly 8 includes a flexible auger 82 located inside the vertical tube 7. A connecting shaft 81 is fixed to the top of the flexible auger 82. A through hole 71 is opened at the top of the vertical tube 7. A bracket 10 is connected to the second motor 9 and the upper surface of the vertical tube 7. The top of the connecting shaft 81 passes through the through hole 71 and is fixedly connected to the output shaft of the second motor 9 by bolts.

[0033] The second motor 9 can drive the flexible auger 82 to rotate, thereby conveying the material at the bottom of the vertical pipe 7 upward through the flexible auger 82. Finally, the material can be discharged along the discharge pipe 11. The material discharged from the discharge pipe 11 will enter the space between the first grinding roller 22 and the second grinding roller 23 for re-grinding, realizing cyclic grinding.

[0034] The bottom end of the vertical tube 7 is connected to a bottom cover 72 by a threaded rotation.

[0035] Since the connecting shaft 81 and the output shaft of the second motor 9 are bolted together, the connecting shaft 81 can be separated from the second motor 9. After unscrewing the bottom cover 72, the flexible auger 82 can be pulled out from the bottom of the vertical pipe 7, making it easy to clean the flexible auger 82 and the inside of the vertical pipe 7. Secondly, after unscrewing the bottom cover 72, the second motor 9 can be started to drive the flexible auger 82 to rotate in the opposite direction, thereby discharging the material from the bottom of the vertical pipe 7.

[0036] Working principle: First, start the three first motors 3 to drive the first grinding roller 22, the second grinding roller 23 and the third grinding roller 24 to rotate. Then start the second motor 9. Then pour the cosmetic raw material to be ground between the first grinding roller 22 and the second grinding roller 23. As grinding proceeds, the surface of the three grinding rollers is covered with raw material. At this time, the scraping component 5 can scrape off the material on the surface of the third grinding roller 24. The material then enters the vertical pipe 7 along the inclined pipe 6. At this time, the second motor 9 drives the soft auger 82 to rotate, which conveys the material in the vertical pipe 7 upward and discharges it through the discharge pipe 11 into the space between the first grinding roller 22 and the second grinding roller 23 for re-grinding until the grinding meets the standard. Then unscrew the bottom cover 72 and start the second motor 9 to reverse the direction, so that the material is discharged from the bottom of the vertical pipe 7.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
