At the same time, the spiral guide groove helps the material to be evenly distributed, reducing residue on the inner and outer walls of the filling head. When filling is nearing completion, the flow regulating valve gradually reduces its opening until it is completely closed, preventing subsequent material from flowing out. When the stepper motor works, the output threaded rod drives the two moving plates on the surface to move in one direction along the guide rod, causing the drive motor on the connecting rod surface to work. Through the drive mounting plate, the flexible scraper moves quickly along the outer wall of the filling head, thoroughly removing residual material. After cleaning is completed, the scraper assembly returns to its initial position, thereby improving the cleaning work.

[0021] 2. In this utility model, the stepper motor is started and works again, and moves in the reverse direction, so that the vacuum pump on the surface of the moving plate approaches the discharge pipe. The vacuum pump starts and sucks in the small residues that the flexible scraper could not remove through the dust suction hood. The residues are then filtered through the filter plate inside the filter box and discharged after purification. After cleaning is completed, the vacuum pump stops working and returns to the initial position with the help of the moving plate, waiting for the next round of filling. The combination of scraping and vacuum suction mechanisms significantly reduces or even eliminates dripping. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1 like Figures 1 to 4 As shown, this utility model provides an anti-drip device for cosmetic filling process, including: a tank 101 is provided on the surface of a support frame 1 for quantitative filling of materials, specifically including: a tank 101, fixedly installed on the inner wall of the support frame 1 near the top, for storing materials to be filled; a discharge pipe 1011, provided at one end of the tank 101, as a material output channel; a stepper motor 102, fixedly installed on the surface of the support frame 1 through a bracket structure, providing power drive; a threaded rod 1021, connected to the output end of the stepper motor 102 and extending along a set direction; and two movable plates 1023, symmetrically threaded on the surface of the threaded rod 1021, which can reciprocate along the threaded rod 1021 under the drive of the stepper motor 102 to realize the position adjustment function.

[0027] In this embodiment, when filling begins, the flow regulating valve 1013 opens, and the material flows into the container through the discharge pipe 1011. At the same time, the spiral guide groove 1012 helps the material to be evenly distributed, reducing the residue on the inner and outer walls of the filling head. When filling is nearing completion, the flow regulating valve 1013 gradually reduces its opening until it is completely closed, preventing subsequent material from flowing out. When the stepper motor 102 works, the output threaded rod 1021 drives the two moving plates 1023 on the surface to move in one direction along the guide rod 1022, causing the drive motor 1025 on the surface of the connecting rod 1024 to work. Through the drive mounting plate 1026, the flexible scraper 1027 moves quickly along the outer wall of the filling head to thoroughly remove residual material. After cleaning is completed, the scraper assembly returns to the initial position, thereby improving the cleaning work.

[0028] Example 2 The inner wall of the discharge pipe 1011 is provided with a spiral guide groove 1012 to optimize the material flow path and reduce the risk of residue. Simultaneously, its outer surface is provided with a flow regulating valve 1013 to facilitate adjustment of the discharge speed according to actual needs, improving filling accuracy and operational flexibility. The scraping assembly includes a connecting rod 1024, on which a drive motor 1025 is fixedly mounted. The output end of the drive motor 1025 is connected to a detachable mounting plate 1026. The surface of the mounting plate is provided with multiple flexible scrapers 1027, symmetrically distributed. The flexible scrapers 1027 can effectively remove residual material from the outer wall of the filling head, preventing dripping and contamination, and facilitating replacement and maintenance. The vacuum dust collection assembly includes... The vacuum pump 103 has its output end connected to the filter box 1031 via a pipe. Multiple filter plates 1032 with round holes are installed inside the filter box by bolts to achieve efficient filtration of the intake gas. A dust suction hood 1033 is provided at one end of the filter box to accurately adsorb residual liquid or dust generated during the filling process, so as to avoid equipment contamination or product appearance defects. A sealing ring 1014 is provided on the outer surface of the spiral guide groove 1012 and is fixed by two symmetrically distributed fastening bolts 1015, so that the sealing ring can fit tightly against the connection surface, effectively preventing material leakage during the filling process. It also supports quick disassembly and replacement, which is convenient for daily cleaning and maintenance.

[0029] In this embodiment, the stepper motor 102 is started to work again and moves in the opposite direction, so that the vacuum pump 103 on the surface of the moving plate 1023 approaches the discharge pipe 1011. The vacuum pump 103 starts and sucks in the small residues that the flexible scraper 1027 could not remove through the dust suction hood 1033. The residues are then filtered through the filter plate 1032 inside the filter box 1031 and discharged after purification. After cleaning, the vacuum pump 103 stops working and returns to the initial position with the help of the moving plate 1023, waiting for the next round of filling. The combination of scraping and vacuum suction mechanisms significantly reduces or even eliminates dripping.

[0030] Working Principle: During use, the support frame 1 provides support for each component. Material inside the tank 101 is conveyed by the discharge pipe 1011. When filling begins, the flow regulating valve 1013 opens, allowing material to flow into the container through the discharge pipe 1011. Simultaneously, the spiral guide groove 1012 helps distribute the material evenly, reducing residue on the inner and outer walls of the filling head. Near the end of filling, the flow regulating valve 1013 gradually decreases its opening until it is completely closed, preventing further material flow. When the stepper motor 102 operates, the output threaded rod 1021 drives two moving plates 1023 along the guide rod 1022 in one direction, causing the drive motor 1025 on the connecting rod 1024 to operate, driving the mounting plate 1026 to... The flexible scraper 1027 moves rapidly along the outer wall of the filling head to thoroughly remove residual material. After cleaning, the scraper assembly returns to its initial position, thereby improving the cleaning process. In addition, the stepper motor 102 is started again and moves in the opposite direction, so that the vacuum pump 103 on the surface of the moving plate 1023 approaches the discharge pipe 1011. The vacuum pump 103 starts and sucks in the small residues that the flexible scraper 1027 could not remove through the dust suction hood 1033. The residues are then filtered through the filter plate 1032 inside the filter box 1031 and discharged after purification. After cleaning, the vacuum pump 103 stops working and returns to its initial position with the help of the moving plate 1023, waiting for the next round of filling. The combination of scraping and vacuum suction mechanisms significantly reduces or even eliminates dripping.
