The utility model relates to the technical field of food canning equipment, in particular to a quantitative filling device for food canning, which comprises a filling table, and a direction adjusting mechanism, a filling mechanism and two groups of supporting grooves which are arranged on the filling table, the direction adjusting mechanism is composed of a rotating disc, a tooth cavity is formed in the lower end of the rotating disc, the rotating disc is connected with an adjusting motor installed on the filling table through the tooth cavity in the bottom, rotating teeth are assembled at the output end of the adjusting motor, the rotating teeth are completely matched with the tooth cavity in the bottom of the rotating disc, and the rotating teeth and the tooth cavity are tightly matched. Connection is achieved through cooperation of a bottom tooth cavity and a rotating tooth of an adjusting motor of a rotating disc in the direction adjusting mechanism, the design structure is relatively simple, the problems that a traditional direction adjusting mechanism is high in component integration degree and complex in structure are solved, when faults occur, troubleshooting and maintenance are easier, the equipment downtime can be effectively shortened, and the production efficiency is improved. The labor cost investment is reduced, so that the production efficiency is improved.

This application provides a doorbell lens structure, including a housing with symmetrical mounting holes on both sides, and a transparent outer lens cover on the front side of the housing; an inner ring mounted on the inner wall of the housing, with a motor mounted on the top side of the inner ring; and a cleaning plate mounted on the bottom surface of the rotating ring within a placement cavity. A gear meshes with the wall of the connecting toothed cavity, driving the gear to rotate and thus the rotating ring to rotate. The sliding cavity rotates under the constraint of a limiting rod mounted on the bottom wall of the inner ring, thereby driving the cleaning plate at the bottom of the rotating ring to rotate. The cleaning plate is elastic. When the cleaning plate rotates two revolutions to the position of the magnet, an external power supply increases the magnetism of the magnet. Under the action of magnetic attraction, the cleaning plate is bent and pressed against the side surface of the magnet, remaining within the placement cavity. When the power is disconnected, the cleaning plate returns to its original shape due to its own elasticity. The motor drives a cotton brush to clean the surfaces of the focusing area, the central viewing area, and the lower viewing area.

A circular saw blade (1) for cutting metal has a disc-shaped base body (2), a tooth chamber (5) which opens toward the radially outer side at the outer periphery of the base body (2), and a bit seat (6) which is recessed at the rear end in the direction of rotation of the tooth chamber (5). The circular saw blade (1) has a bit (10) which is mounted in the bit seat (6) and projects radially outward beyond the base body (2). The bit (10) has a blade thickness which is thicker than the thickness (2c) of the base body (2). The bit (10) has a thin-walled portion (15) on the radially inner side which has a thickness which is less than the thickness (2c) of the base body (2). In the thickness direction, the thin-walled portion (15) is located within the thickness of the bit seat (6).

A circular saw blade (1) has a disc-shaped base body (2). The circular saw blade (1) has a plurality of tooth chambers (10) recessed in an outer periphery (2b) of the base body (2). The circular saw blade (1) has a plurality of tips (5) engaged with the outer periphery (2b) of the base body (2). The plurality of tooth chambers (10) includes deep tooth chambers (11) having a tooth chamber depth (11a) of 1.13 to 1.60 times an average tooth chamber depth. The plurality of tooth chambers (10) includes shallow tooth chambers (12) having a tooth chamber depth (12a) of 0.60 to 0.95 times the average tooth chamber depth. The circular saw blade (1) has a deep region (14) including only 2 to 3 continuous deep tooth chambers (11) and a shallow region (15) including only 2 to 7 continuous shallow tooth chambers (12).

The application provides a stepped labyrinth sealing structure with a shunt passage. The shunt passage is arranged between the two steps of the sealing bush, so that part of the airflow is backflowed into the shunt passage before the tooth top of the second step, thereby inhibiting the leakage of the airflow. The inlet of the shunt passage is arranged between the first step and the second step of the bush, and the outlet is arranged on the second step. After the airflow flows through the first step of the labyrinth, the airflow is divided into two parts, one part of the airflow flows to the second step along the original labyrinth passage, and the other part flows into the shunt passage. The airflow in the shunt passage is subjected to the frictional resistance of the wall surface, so that the pressure is reduced. The pressure at the outlet of the shunt passage is lower than the pressure in the tooth cavity between the first step and the second step of the labyrinth, so that the airflow is backflowed into the shunt passage before the gap between the tooth tops of the second step of the labyrinth, and the leakage flow of the airflow is reduced. The method can improve the sealing performance of the labyrinth without affecting other system functions, without changing the structural parameters such as the size and position of the labyrinth sealing, and the method is simple and feasible.
