Description

Technical Field

[0001] The utility model relates to the field of cosmetics, in particular to a loose powder raw material grinding device. Background Art

[0002] In the cosmetics industry, especially in the field of loose powder manufacturing, the requirements for powder fineness and uniformity are increasing. In the traditional loose powder production process, manual or simple mechanical methods are often used for grinding, which have problems such as low grinding efficiency, unstable product quality, and high production costs. In order to solve these problems, a loose powder raw material grinding device was developed, which is designed to improve production efficiency, optimize grinding accuracy, and ensure the quality and uniformity of the final product.

[0003] Existing loose powder grinding devices mostly use simple friction grinding principles, such as the friction between a rotating grinding disc and a fixed grinder. However, these devices often encounter problems such as uneven grinding and short equipment life when processing different powder materials. In addition, the existing technology usually lacks the ability to adjust to different powder characteristics, such as flexible conversion between coarse and fine grinding, and control of the heat generated during the grinding process and material fluidity.

[0004] The existing device has made some improvements in the flattening and cutting of the workpiece, but there are still some limitations in practical applications: 1. Insufficient grinding uniformity: Due to the simple design of the friction mechanism between the grinding disc and the fixed grinder, it is difficult for the device to achieve uniform grinding of the material, resulting in uneven particle size and particle distribution of the final product. Utility Model Content

[0026] The following will be combined with the attached examples of the present utility model Figure 1-6 The technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution: a loose powder raw material grinding device, comprising a frame 1, a grinding cylinder 2 is fixed at the upper end of the frame 1, a driving motor 3 is fixed at the lower end of the frame 1, a rotating shaft 4 is transmission-connected to the upper end of the driving motor 3, a coarse grinding mechanism 5 is arranged in the middle of the grinding cylinder 2, and a fine grinding mechanism 6 is arranged at the bottom of the grinding cylinder 2; a guide cylinder 7 is fixed at the inner edge of the grinding cylinder 2, and the guide cylinder 7 is a hollow cone with a larger upper part and a smaller lower part.

[0028] Among them, the frame 1 provides the basic structural support and stability of the device, fixes and supports the grinding cylinder 2, the drive motor 3 and other key components. The grinding cylinder 2 is mounted on the frame and fixed by the support of the frame. The grinding cylinder, as the main body of the grinding process, accommodates the coarse grinding mechanism 5 and the fine grinding mechanism 6, and realizes the grinding action through the transmission of the rotating shaft 4. The drive motor 3 is mounted at the lower end of the frame, and provides power through the rotating shaft 4 to drive the grinding cylinder 2 and the coarse grinding mechanism 5 and the fine grinding mechanism 6 thereon to rotate. The rotating shaft 4 is connected to the upper end of the drive motor 3 and penetrates to the middle of the grinding cylinder 2. The rotating shaft transmits the power of the drive motor so that the grinding cylinder and the grinding mechanism thereon can rotate, thereby performing the grinding operation. The coarse grinding mechanism 5 is located in the middle of the grinding cylinder 2, including a rotating plate 51 and a plurality of groups of grinding blades 52. The coarse grinding mechanism is responsible for the preliminary grinding of the raw materials, and the raw materials are cut and crushed by the rotating blades to prepare for the subsequent fine grinding mechanism 6. The fine grinding mechanism 6 is located at the bottom of the grinding cylinder 2, and is mainly composed of a grinding disc 61 and a wavy serrated grinding tooth 611. The fine grinding mechanism further refines and evenly grinds the raw materials through the rotation of the grinding disc and the design of the serrated grinding teeth to achieve the required particle size and uniformity. The guide cylinder 7 is fixed to the inner edge of the grinding cylinder 2 and is in the shape of a hollow cone with a larger upper part and a smaller lower part. The guide cylinder plays a role in guiding and dispersing the raw materials during the grinding process, which helps to adjust and optimize the grinding effect, and also helps to control the flow and distribution of materials during the grinding process.

[0029] The rough grinding mechanism 5 includes a rotating plate 51 which is connected to the top of the output shaft of the rotating shaft 4. A plurality of grinding blades 52 are fixed to the top of the rotating plate 51. The rotating plate 51 is fixed to the top of the output shaft 4 and directly receives the power from the driving motor. It transmits kinetic energy to the grinding blades 52 through rotational motion, thereby driving the grinding blades 52 to rotate.

[0030] There are a plurality of filter holes 511 arranged in a circumferential array on the rotating plate 51. These filter holes 511 are located on the circumference of the rotating plate 51, and their function is to allow the ground powder material to pass through. The existence of the filter holes can effectively screen and separate the materials, ensuring that only powder particles of the required size can pass through, thereby ensuring the uniformity of the particle size and the stability of the quality of the product.

[0031] The grinding blade 52 includes a fixing seat 521 . A straight blade 522 is arranged in the horizontal direction of the fixing seat 521 , and an oblique blade 523 is arranged in the vertical direction of the fixing seat 521 .

[0032] The fixing base 521 provides a basic structure for supporting and fixing the straight knife 522 and the bevel knife 523, ensuring the stability and accuracy of the blades during operation. The horizontally arranged straight knife 522 is mainly responsible for cutting and grinding the feed raw materials. Its blade directly contacts and cuts the powder material to quickly and effectively achieve the purpose of coarse grinding. Compared with the straight knife 521, the vertically arranged bevel knife 523 is more suitable for processing uneven particles or fibrous materials in the feed. The bevel design of the bevel knife helps to effectively guide the material to the cutting area of ​​the straight knife, thereby improving the efficiency and uniformity of grinding.

[0033] Through the rotation of the rotating plate, these parts enable the grinding blades fixed on them to effectively cut, grind and crush the incoming loose powder raw materials, thereby completing the task of the rough grinding stage. Its structure and design enable the grinding blades to accurately control and process materials during high-speed rotation, laying a good foundation for the subsequent fine grinding stage.

[0034] The fine grinding mechanism 6 includes a grinding disc 61 which is transmission-connected to the middle of the rotating shaft 4 , and a grinder 62 is fixed to the upper end of the grinding cylinder 2 .

[0035] The lower surface of the grinding disc 61 is provided with wavy serrated grinding teeth 611, and the shape of the grinding teeth 611 diverges from the axis to the surroundings, and the upper surface of the grinding disc 61 is provided with a plurality of feed ports 612 that penetrate to the middle. The wavy serrated grinding teeth 611 are located on the lower surface of the grinding disc, and their shape diverges from the axis of the grinding disc to the surroundings. The wavy design helps to increase the surface area of ​​contact between the grinding teeth and the powder material, thereby improving the efficiency and uniformity of the grinding. Through the change of the wavy shape, loose powder raw materials of different sizes and shapes can be effectively crushed and pulverized to ensure the comprehensiveness and efficiency of the grinding process. The feed port 612 is arranged on the upper surface of the grinding disc and penetrates to the middle. These feed ports are used to guide the raw material powder to the grinding tooth area, so that the material can be evenly distributed on the grinding teeth of the entire grinding disc. Through reasonable layout and design, the feed port helps to control the flow and distribution of the material, ensuring that each grinding tooth can fully participate in the grinding process, thereby improving the efficiency and consistency of the grinding.

[0036] The upper surface of the grinder 62 is provided with annular auxiliary grinding lines 621. The annular auxiliary grinding lines 621 are designed on the upper surface of the grinder, and their main function is to further process and grind the loose powder raw materials in the final grinding stage. These auxiliary grinding lines increase the grinding capacity of the grinder through their uneven surface structure, which helps to further refine the particle size and texture of the powder. And improve product uniformity: the design of the auxiliary grinding lines can form more complex grinding channels and increase the grinding surface area inside the grinder, so that the loose powder raw materials can be processed more evenly in the final grinding stage. This helps to eliminate the unevenness between particles and ensure the quality and consistency of the final product. By adding auxiliary grinding lines to the grinder, the device can process more loose powder raw materials in the same time, thereby improving production efficiency and the overall utilization of the device.

[0037] The working principle is divided into the following stages:

[0038] 1. Raw material feeding: Raw materials enter the device from above the grinding cylinder 2. A grinder 62 is fixed to the upper end of the grinding cylinder to receive and guide the feeding loose powder raw materials.

[0039] 2. Start and drive: After the drive motor 3 is started, the rotating shaft 4 drives the entire device to rotate through the transmission connection. The rotating force of the rotating shaft drives the coarse grinding mechanism 5 and the fine grinding mechanism 6 to rotate.

[0040] 3. Rough grinding process: The raw material first enters the rough grinding mechanism 5, where multiple groups of grinding blades 52 crush and refine the raw material particles through rotation.

[0041] The refined particles fall through the filter holes 511 on the rotating plate 51 to separate larger particles or unground impurities.

[0042] 4. Feed guiding and fine grinding: The refined particles are guided by the guide cylinder 7 and enter from the multiple feed ports 612 on the grinding disc 61.

[0043] On the lower surface of the grinding disc, wavy sawtooth grinding teeth 611 radiate from the axis to the surroundings, and further finely grind the particles through the action of rotation and centrifugal force.

[0044] 5. Grinding and collection: The annular auxiliary grinding lines 621 of the grinder 62 continue to process the particles during the grinding process to ensure that they reach the required particle size and quality standards. The powder after grinding is manually taken out through the discharge port 21 and used as a final product or further processed.

[0045] This device realizes a continuous process from coarse grinding to fine grinding through rotation and a specially designed grinding structure, ensuring the uniformity and particle size control of loose powder raw materials, and is suitable for producing high-quality ground products.
