Once the loading sensor detects one end of the bullet-taking fixing plate 241, the loading sensor sends a loading signal, and the loading program controls the first electric push rod 242 to drive the bullet-taking moving plate 243 to release a bullet C according to the loading signal, so that the bullet C falls into the bullet loading port, and in this embodiment, after the bullet C falls into the bullet loading port, the processor further performs a loading action on the bullet C by controlling the moving unit 20, i.e., the bullet C is pushed towards the barrel a2 for a predetermined distance along the first horizontal direction, so that the head of the bullet C enters the barrel a 2.
The loading process issues a fill completion signal after a delay of a third predetermined time based on the loading signal, and the deposit sensor is configured to issue a cycle signal or a reset signal based on whether the cartridge C of the magazine accommodating case 32 can be detected.
The processor executes a bullet receiving program according to the filling completion signal and the cycle signal, and the reset program enables the bullet taking assembly 240 to move to a preset initial position by controlling the bullet moving unit 20 according to the filling completion signal and the reset signal.
Once the shielding sensor recorded by the counter detects that the number of times of the bullet C falling into the bullet falling inlet 31122 is a predetermined number, the counter sends a magazine change signal to the processor, and the processor controls the second electric push rod 331 to drive the gate plate 332 to open the bullet falling inlet 31122 by a predetermined width according to the magazine change signal.
The above embodiments are preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications or changes that can be made by those skilled in the art without inventive skill within the scope of the appended claims will still fall within the scope of the present invention.
