[0039] In the embodiment, the chuck 53 is connected with a motor 7, the chuck 53 is located in the rotating arm pressing structure 52, the rotating arm pressing structure 52 is connected with the electric push rod 8 on the rotating arm mechanism 5, and under the pushing of the electric push rod 8, the rotating arm pressing structure 52, the chuck 53 and the motor 7 are driven to move downward as a whole, so that the chuck 53 abuts against the powder bottle 6.

[0040] In the embodiment, the bottle body guide sleeve 61 is further provided with a rotating rod guide piece 62, the rotating rod guide piece 62 abuts against the discharging rotating rod 63, a part of the discharging rotating rod 63 abutting against the rotating rod guide piece 62 is provided with a spiral guide rib, the discharging rotating rod 63 is connected with the switching groove of the discharging shutter 64 between the opened powder adding opening 641 and the closed powder adding opening 641, the bottle body guide sleeve 61 abuts against the spiral guide rib of the discharging rotating rod 63 through the rotating rod guide piece 62 in the downward process, so that the discharging rotating rod 63 is driven to rotate, and the discharging shutter 64 fixed on the discharging rotating rod 63 is deflected, so that the action of opening or closing the powder adding opening 641 is realized.

[0041] In the embodiment, the spring guide rod 66 is installed between the bottle body guide sleeve 61 and the bottle body positioning part 67, when the bottle body guide sleeve 61 is pressed by the rotating arm pressing structure 52, the spring on the spring guide rod 66 is compressed, the discharging rotating rod 63 is rotated to drive the discharging shutter 64 to rotate, the discharging shutter 64 is rotated from the closed powder adding opening 641 position to the opened powder adding opening 641 position, and the powder adding opening 641 is opened, when the pressure is removed, the bottle body guide sleeve 61 is reset under the elastic force of the compressed spring of the spring guide rod 66, the powder adding opening of the powder bottle 6 is closed, that is, the discharging shutter 64 is rotated from the opened powder adding opening 641 position to the closed powder adding opening 641 position.

[0042] In use, the powder bottle 6 needs to be used in conjunction with the rotating arm mechanism 5. The powder bottle 6 is placed in the correct position on the rotating arm mechanism 5. Then, the electric push rod 8 drives the rotating arm pressing structure 52 to press down the bottle body guide sleeve 61 of the powder bottle 6. During the downward movement, the bottle body guide sleeve 61 is driven by the rotating rod guide plate 62 fixed on the bottle body guide sleeve 61, causing the feeding rod 63 to rotate, thereby causing the discharge baffle 64 to deflect from the closed powder filling port 641 position to the open powder filling port 641 position, opening the powder filling port of the powder bottle 6.

The limiting post 612 is fixed to the bottle body of the powder bottle 6 and is used to limit the movement of the bottle body guide sleeve 61 as it slides up and down along the bottle body of the powder bottle 6.

[0044] In this embodiment, see Figures 4 to 11 As shown, the bottle positioning part 67 is an octagonal oblique angle structure, used for positioning and preventing rotation when the bottle is placed on the bottle limiting port on the rotating arm mechanism support table 51. The top of the powder bottle 6 is provided with a bottle cap 65 and the bottom is provided with a bottle bottom 68. A separate powder feeding screw 69 is installed in the powder bottle 6 between the bottle cap 65 and the bottle bottom 68. The powder feeding screw 69 includes an upper feeding screw and a lower feeding screw. The upper feeding screw is installed together with the bottle cap 65. The upper end of the upper feeding screw is provided with a boss for nesting connection with the chuck 53. When the chuck 53 is pressed down, the sleeve-type chuck 53 can be sleeved on the boss. Under the drive of the motor 7, the powder feeding screw 69 is rotated to realize powder feeding.

[0045] In this embodiment, the upper feeding screw is installed along the central axis of the bottle cap 65 via a ball bearing 610, and a shaft retaining ring 616 is provided between the upper feeding screw and the ball bearing 610. The upper feeding screw inside the bottle cap 65 is connected to the lower feeding screw, and a bottle cap cover plate 615 is provided on the outside of the bottle cap 65 to cover the ball bearing 610.

[0046] In this embodiment, the lower feeding screw is installed inside the body of the powder bottle 6 via a central support 618. A flange bearing 614 is provided between the lower feeding screw and the central support 618. A shaft retaining ring 616 is provided between the flange bearing 614 and the lower feeding screw. A stirring rod 613 is installed on the lower feeding screw.

[0047] In the embodiment, the bottom end of the lower feeding screw is limited in the powder feeding opening in the middle of the bottle body positioning part 67 by the shaft guide sleeve 617, the upper feeding screw is installed on the bottle cap 65, the lower feeding screw is installed in the bottle body of the powder bottle 6, and the bottom of the upper feeding screw is provided with a U-shaped joint for butt joint with the inverted U-shaped joint of the top of the lower feeding screw.

[0048] When the powder discharging action is performed, the arm down structure 52 presses down the bottle body guide sleeve 61 of the powder bottle 6, and the chuck 53 clamps the upper powder feeding screw of the powder feeding screw 69 of the powder bottle 6, then the motor 7 drives the chuck 53 to rotate to make the powder feeding screw 69 of the powder bottle 6 rotate synchronously, the chuck 53 drives the powder feeding screw 69 of the powder bottle 6 to rotate clockwise, and the thread of the powder feeding screw 69 guides the powder in the bottle to the powder discharging opening; the stirring rod 613 fixed on the powder feeding screw 69 stirs the powder in the bottle, ensures uniform and smooth discharging process, and prevents powder caking to a certain extent.

[0049] In the embodiment, the powder feeding screw 69 of the powder bottle 6 adopts a separable design, the upper segment (upper powder feeding screw) of the powder feeding screw 69 is taken out with the bottle cap 65, and the lower segment (lower powder feeding screw) is left in the working position in the bottle body of the powder bottle 6, so that the whole screw rod does not need to be taken out every time powder is added, and the following disadvantages of taking out the whole screw rod can be solved.

[0050] 1. When the screw rod is inserted into the bottle cavity filled with powder, a large resistance is encountered, and the efficiency is reduced.

[0051] 2. After the powder is added, the powder discharging opening is covered, the screw rod is difficult to align with the powder discharging opening when the user inserts the screw rod back, and the inner wall of the bottle cavity is easily scratched.

[0052] 3. Frequent insertion and extraction accelerate the wear of the shaft guide sleeve of the powder discharging opening, and affect the smoothness of powder discharging and the service life of the powder bottle.

[0053] In summary, the automatic powder adding device provided by the application fixes the powder bottle 6 above the mother liquor bottle 4 by the arm mechanism 5, bears the mother liquor bottle 4 by the electronic balance 2, presses down the bottle body guide sleeve 61 of the powder bottle 6 by the arm down structure 52 under the driving of the electric push rod 8, drives the discharging rotating rod 63 to rotate by the rotating rod guide piece 62 of the bottle body guide sleeve 61, drives the discharging shutter 64 to open the powder feeding opening, rotates the powder feeding screw 69 by the motor 7, and performs the powder adding action under the cooperation of the powder feeding screw 69 and the stirring rod 613, so that the powder adding operation is convenient and fast, the automation degree is high, and the powder adding operation is convenient.
