[0019] An inner baffle plate 14 and an outer baffle plate 15 are provided on the fixed plate 13 and are parallel to each other. A buffer zone 16 is formed between the inner baffle plate 14 and the outer baffle plate 15 . The width of the buffer zone 16 is greater than the inner diameter of the steel ball.

[0020] In the utility model, according to the size of the steel balls, the fixed plate 13 is driven downward on the fixed frame 12 by the driving member 2, and the distances between the inner baffle plate 14, the outer baffle plate 15 and the guide plate 11 are adjusted so that the required steel balls can pass between the outer baffle plate 15 and the guide plate 11, and the inner baffle plate 14 and the guide plate 11, and the steel balls exceeding the specifications are first blocked by the outer baffle plate 15. If a certain position at the bottom of the outer baffle plate 15 is worn, the steel balls exceeding the specifications will enter the buffer zone 16 and be accommodated inside the buffer zone 16, and be blocked by the inner baffle plate 14, thereby playing a double protection role, ensuring that the steel balls exceeding the specifications will not be mixed with the steel balls of normal specifications.

[0021] In the present utility model, as a preferred solution, both ends of the above-mentioned fixed plate 13 are provided with outer slide rails 3 parallel to each other, and two outer slide grooves 31 are fixed on the fixed frame 12, and the outer slide grooves 31 are slidably connected with the outer slide rails 3;

[0022] An inner slide groove 32 fixed on the fixed plate 13 is provided at the center position between the two outer slide rails 3. The driving member 2 includes a rotating motor 21 and an inner slider 22 arranged on the fixed frame 12. The inner slider 22 is slidably arranged on the inner slide groove 32. A screw rod 33 is provided at the output end of the rotating motor 21. An adjusting threaded hole 34 is provided on the inner slider 22. The screw rod 33 is threadedly connected to the adjusting threaded hole 34.

[0023] In the present invention, the outer slide rail 3 slides inside the outer slide groove 31, and cooperates with the inner slide block 22 to slide on the inner slide groove 32, thereby improving the stability of the up and down movement of the fixed plate 13. At the same time, the up and down movement of the fixed plate 13 is driven by the rotating motor 21, and the interaction of the screw rod 33 and the adjusting threaded hole 34 drives the inner slide block 22 to move up and down on the inner slide groove 32, thereby driving the fixed plate 13 to move up and down as a whole.

[0024] In the utility model, as a preferred solution, a card slot 4 is provided at the connection between the inner slide groove 32 and the fixed plate 13, a fixing groove 41 of the rotating motor 21 is provided on the fixed frame 12, and a card plate 42 extending downward is provided on the fixed groove 41, and the card plate 42 is slidably arranged inside the card slot 4.

[0025] In the present invention, during the up-and-down movement of the fixing plate 13 , the clamping plate 42 moves synchronously inside the clamping slot 4 , further guiding the up-and-down movement of the fixing plate 13 .

[0026] In the utility model, as a preferred solution, two raised positioning blocks 5 are provided on the fixing plate 13 , and the inner material stop plate 14 is fixed at the bottom of the connection line of the two positioning blocks 5 .

[0027] In the present invention, the positioning block 5 plays a role in positioning the installation of the inner material blocking plate 14 .

[0028] In the utility model, as a preferred solution, the outer baffle plate 15 is provided with two positioning holes 51 , and the inner baffle plate 14 is provided with a clamping block 52 . The positioning block 5 is correspondingly clamped in the inside of the positioning hole 51 , so that the outer baffle plate 15 is fitted and fixed on the clamping block 52 .

[0029] In the present invention, the clamping block 52 serves to fix the outer material stopper plate 15 , and at the same time, the positioning hole 51 and the positioning block 5 are mutually clamped, so as to position the installation position of the outer material stopper plate 15 .

[0030] In the utility model, as a preferred embodiment, the downward inclined direction of the material guide plate 11 is set to x, the bottom of the inner material baffle plate 14 is provided with an inner inclined surface 6 in contact with the steel ball, and the inclination direction of the inner inclined surface 6 is consistent with the x direction, and the bottom of the outer material baffle plate 15 is provided with an outer inclined surface 61 in contact with the steel ball, and the inclination direction of the outer inclined surface 61 is consistent with the x direction.

[0031] In the utility model, the steel ball slides down along the x direction on the guide plate 11.

When the inner material blocking plate 14 blocks the steel ball, the inner inclined surface 6 contacts the steel ball. The setting of this inclined surface increases the contact area between the steel ball and the outer inclined surface 61 or the inner inclined surface 6, thereby ensuring the stability of the steel ball being blocked.
