Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling machine technology, and in particular to a filling machine for powder filling. Background Technology
[0002] In related technologies, powder filling machines generally adopt an automatic intermittent filling method. The powder filling machine includes a filling machine body, which includes a feeding pipe. The feeding pipe is installed at a designated position on the worktable and fills at a speed of 63 to 75 cans per minute. After filling, the cans are conveyed by a mesh conveyor to various surrounding can sealing equipment. During the time that the cans stay at each can sealing machine, various operations such as capping, vacuuming, nitrogen filling, and sealing are carried out automatically at the same time.
[0003] Powder filling machines are widely used in the food, pharmaceutical, chemical, and pesticide industries. They are primarily used for filling powdered or fine granular materials with uniform physical properties and minimal density variation. The working principle of a powder filling machine is based on physical mechanics principles. By applying certain pressure and time, the powder material undergoes plastic deformation or flow and recombination within a mold or container, resulting in a molded product with a specific shape, size, and density. During the filling process, the machine typically employs a screw metering method. Different screw specifications and settings for the number of rotations and rotation speed are used to achieve different metering ranges. Simultaneously, the machine also uses a PLC-controlled motor to drive the metering screw and features a touchscreen human-machine interface for easier and more intuitive operation.
[0004] The above-mentioned device has the following drawbacks: due to the extremely fine powder, powder residue is easily left in the filling machine body during the production and filling process, which affects the filling and conveying of the cans, causing production to be unsmooth and requiring repeated cleaning of the filling machine body, which increases the risk of contamination of the inner wall of the product by manual cleaning. Therefore, a powder filling machine is proposed to solve the above problems. Utility Model Content

The bottom of the inclined scraper 55 is rotatably connected to a shaft disk 56 through a bearing. A discharge hole 57 is opened on the inner side wall of the shaft disk 56.
[0025] Reference Figures 2-3 The rotating rod 4 passes through the bottom outer wall of the filling machine frame 1. The end of the telescopic spring 53 away from the sliding plate 52 is fixedly connected to the outer wall of the vertical scraper 54. The vertical scraper 54 is used to scrape away the dirt on the inner wall of the filling machine cover 50. The vertical scraper 54 is slidably connected to the inner wall of the side of the filling machine cover 50. There are two oblique scrapers 55, which are symmetrical to each other. The shaft disk 56 is slidably connected to the outer wall of the side of the rotating rod 4. There are several discharge holes 57, which are respectively opened on the inner wall of the side of the shaft disk 56. The bottom outer wall of the filling machine frame 1 is fixedly connected to the support frame 2, and the top outer wall of the filling machine frame 1 is fixedly connected to the heat dissipation mesh plate 3.
[0026] Reference Figures 3-4 The adjusting mechanism 6 includes a T-slot 61, which is located on the inner side wall of the filling machine cover 50.

[0027] Working principle: Powder is loaded into the filling machine cover 50, and then the rotating rod 4 is turned to rotate the sliding plate 52 in the limiting port 51. The rotation of the sliding plate 52 drives the vertical scraper 54 to rotate, so that the vertical scraper 54 scrapes the inner wall of the filling machine cover 50. The rotation of the vertical scraper 54 drives the oblique scraper 55 to rotate, so that the oblique scraper 55 scrapes the residual stains on the inner wall of the hopper cover 63. By rotating the nut bracket 66, it is separated from the threaded ring 64. Then, the hopper cover 63 is pulled to separate from the filling machine cover 50. The movement of the hopper cover 63 drives the T-block 62 to move, so that the T-block 62 is separated from the T-slot 61. Then, the sliding plate 52 moves downward and moves out of the limiting port 51, so that the inner wall parts and the inner wall are easy for personnel to clean and maintain.
