Description

Technical Field

[0001] This utility model belongs to the technical field of flour screening machines, and in particular relates to a flour screening machine with a scraping structure. Background Technology

[0002] Flour screening machines are specialized equipment used in flour processing to remove impurities, grade particles, or improve flour quality. They are widely used in flour mills, food processing plants, and other fields.

[0003] In existing flour screening machines, flour tends to accumulate on the screen, leading to low screening efficiency and even screen clogging. Therefore, we propose a flour screening machine with a scraping structure. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a flour screening machine with a scraping structure, thereby preventing flour from accumulating on the screen.

[0005] In view of this, the present invention provides a flour screening machine with a scraping structure, including a base, a spring fixedly connected to the top of the base, a screening frame fixedly connected to the top of the spring, a working motor fixedly connected to the bottom of the screening frame, a rotating shaft fixedly connected to the output end of the working motor, a vibrating wheel fixedly connected to the bottom of the rotating shaft, a connecting ring fixedly connected to the top of the rotating shaft, a scraper plate welded to the outer wall of the connecting ring, a bracket fixedly connected to the inside of the screening frame and fitted to the bottom of the scraper plate, a screen fixedly connected to the top of the bracket, a screening port provided below the screen on the side wall of the screening frame, a discharge port provided above the screen on the side wall of the screening frame, a threaded seat fixedly connected to the top of the discharge port, a screw threadedly connected to the inner wall of the threaded seat, a partition plate fitted into the bottom of the screw, and a limit groove provided at the connection between the discharge port and the partition plate.

[0006] Based on the above structure, the rotating shaft drives the eccentric vibrating wheel to rotate, and then the screen inside the screening frame vibrates through six sets of springs to screen the flour. At the same time, the rotating shaft drives the scraper to rotate through the connecting ring, scraping the flour on the screen, which improves the screening efficiency of the flour and avoids screen blockage.

[0007] Preferably, the central axis of the base coincides with the central axis of the screening frame, and six sets of springs are provided. The six sets of springs are distributed in a circular pattern at equal angles about the central axis of the screening frame. In this embodiment, by providing six sets of springs, it is beneficial to improve the stability of the vibration of the screening frame.

[0008] Preferably, the vibrating wheel is eccentric in shape. In this embodiment, by setting the vibrating wheel to be eccentric, it is easy for the rotating shaft to rotate and drive the eccentric vibrating wheel to rotate. Then, the screen inside the screening frame vibrates through six sets of springs to screen the flour.

[0009] Preferably, the scraper is arc-shaped, and there are three sets of scraper plates. The three sets of scraper plates are distributed in a circle at equal angles about the center of the connecting ring. In this embodiment, by setting three sets of scraper plates, the rotation of the shaft drives the scraper plates to rotate through the connecting ring, thereby scraping the flour on the screen and avoiding screen blockage.

[0010] Preferably, the scraper plate forms a scraping structure with the screen through a connecting ring and a rotating shaft. In this embodiment, the scraper plate rotates to scrape the flour on the screen, which helps to improve the screening efficiency of the flour.

[0011] Preferably, the cross-section of the partition is arc-shaped, and the center of the cross-section of the partition coincides with the central axis of the screening frame. In this embodiment, it is convenient for the scraper to rotate and drive large flour particles to be discharged from the discharge port.

[0012] Preferably, the discharge port forms an opening and closing structure with the screening frame through a screw and a partition. In this embodiment, the rotation of the screw drives the partition to slide along the groove of the limiting groove through the threaded seat, thereby realizing the opening and closing operation of the discharge port.

[0013] The beneficial effects of this utility model are: 1. This flour screening machine with a scraping structure uses a scraping plate and a rotating shaft to drive an eccentric vibrating wheel. The screen inside the screening frame vibrates through six sets of springs to screen the flour. At the same time, the rotating shaft drives the scraping plate to rotate through a connecting ring, scraping the flour on the screen. This improves the screening efficiency and prevents the screen from clogging.

[0014] 2. This flour screening machine with a scraper structure, by setting up a partition, allows small flour particles to be discharged through the screening port. Then, the operator rotates the screw, and the rotation of the screw drives the partition to slide along the groove of the limiting groove through the threaded seat, so that the scraper rotates and drives the large flour particles to be discharged from the discharge port.
