[0033] It should be noted that the rotation of first motor 703 drives the rotation of first rotating shaft, the rotation of first rotating shaft drives the rotation of dispersion rod 704, dispersion rod 704 disperses the ink, and the air pipe 705 is arranged to make material collecting barrel 3 and the outside air flow.

[0034] As shown in the figure, Figure 3 Clamping mechanism 9 includes first clamping unit, second clamping unit and third clamping unit, which are evenly arranged around material collecting barrel 3, first clamping unit includes mounting plate 901 vertically fixed on lifting plate 8, first sliding rod 902 is inserted into the sleeve on mounting plate 901, first clamping block 903 for clamping material collecting barrel 3 is fixed on the end of first sliding rod 902 close to material collecting barrel 3, locking block 904 is vertically arranged on the other end of first sliding rod 902, first return spring 905 is sleeved on first sliding rod 902 and located between first clamping block 903 and mounting plate 901, locking plate 906 for locking locking block 904 is horizontally arranged below locking block 904, one end of locking plate 906 close to material collecting barrel 3 is hinged with lifting plate 8, first air cylinder 907 is obliquely arranged below locking plate 906, output shaft end of first air cylinder 907 is hinged with the other end of locking plate 906, and bottom end of first air cylinder 907 is hinged with lifting plate 8.

[0035] It should be noted that the output shaft of the first cylinder 907 moves to the right, causing the locking plate 906 to move to the right. The rightward movement of the locking plate 906 causes the locking block 904 to move to the right. A first return spring 905 is sleeved on the first slide rod 902 and located between the first clamping block 903 and the mounting plate 901. Due to the presence of the first return spring 905, it is in a compressed state at this time. When the locking block 904 moves to the right, the first return spring 905 exerts a force to the left on the first clamping block 903, thereby ensuring that the first clamping block 903 still clamps the collection bucket 3.

[0036] As attached Figure 3 As shown, the second clamping unit includes an L-shaped clamping rod 908 vertically mounted on the lifting plate 8. A second clamping block 909 for clamping the collection bucket 3 is fixed at the L-shaped end of the L-shaped clamping rod 908, and the other end is hinged to the lifting plate 8. A slide rail 910 is horizontally fixed on the lifting plate 8 next to the L-shaped clamping rod 908. A slider 911 is embedded in the slide rail 910. A second connecting rod 912 is inclined between the slider 911 and the L-shaped clamping rod 908.

One end of the elastic rope 916 is fixedly connected to the second rotating shaft, and the other end is fixedly connected to the side wall of the slider 911.

[0039] It should be noted that when the collection bucket 3 needs to be clamped, the locking plate 906 moves to the right, pulling the elastic rope 916 to the right. The elastic rope 916 moves to the right, pulling the slider 911 to slide forward on the slide rail 910. The slider 911 slides forward, causing the second connecting rod 912 to slide forward. The second connecting rod 912 slides forward, causing the L-shaped clamping rod 908 to slide forward, thereby clamping the collection bucket 3 with the second clamping block 909. The structure of the third clamping unit is the same as that of the second clamping unit. Thus, the collection bucket 3 is clamped by the cooperation of the first clamping unit, the second clamping unit, and the third clamping unit. By setting the clamping mechanism 9, the collection bucket 3 can be stabilized during the operation of the grinding and dispersing device, thereby improving the ink dispersion effect.

Figure 3

[0041] It should be noted that the inclined teeth 917 and the inclined surface can better lock the locking block 904.

Figure 1 It should be noted that when the aggregate bucket 3 does not need to be clamped, the locking plate 906 first unlocks the locking block 904, and then because the second reset spring 913 is arranged, at this time the second reset spring 913 is in a stretched state, the second reset spring 913 gives the sliding block 911 a rightward force, so that the sliding block 911 slides backward on the sliding rail 910, so that the second clamping block 909 does not clamp the aggregate bucket 3, and at the same time the elastic rope 916 moves leftward, so that the elastic rope 916 can.

[0046] It should be noted that when the aggregate bucket 3 does not need to be clamped, the locking plate 906 first unlocks the locking block 904, and then because the second reset spring 913 is arranged, at this time the second reset spring 913 is in a stretched state, the second reset spring 913 gives the sliding block 911 a rightward force, so that the sliding block 911 slides backward on the sliding rail 910, so that the second clamping block 909 does not clamp the aggregate bucket 3, and at the same time the elastic rope 916 moves leftward, so that the elastic rope 916 can.
