[0002] Nano color paste is divided into water-based nano color paste and alcohol-soluble nano color paste. The characteristic is that it reaches the nano level. Color paste refers to mixing some colored toner with water or solvent, and then adding dispersant and some ingredients to make it liquid. After mixing in a high-speed mixer, it enters the nano grinder and zirconium beads for high-speed shearing to meet the requirements of the finished product. Generally speaking, color paste is composed of pigment, dispersant, wetting agent and dispersion medium-solvent. According to the different dispersion media, color paste can be divided into two categories; pigment type color paste made by dispersing pigment particles in water with water as dispersion medium is called water-based color paste, and a certain amount of defoaming agent must be added during the preparation process; similarly, pigment type color paste made by dispersing pigment particles in alcohol solvent with alcohol as dispersion medium is called alcohol-soluble color paste.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, the present invention provides a fully automatic filtering device for inkjet nano-color paste, comprising a filter box 1, the side wall of the filter box 1 comprises an upper side wall 11 and a lower side wall 12 which are distributed up and down and are integrally formed, the diameter of the upper side wall 11 is slightly smaller than the lower side wall 12, and a plurality of filter screens 2 distributed in a circumferential array are arranged in the filter box 1;

[0033] The outer side of the filter box 1 is provided with a disassembly mechanism for driving the filter screen 2;

[0034] The filter box 1 is provided with an adjustment mechanism for driving the filter screen 2 to adjust its angle;

[0035] The outside of the filter box 1 is provided with a stirring mechanism for driving the filter screen 2 to rotate.

[0036] With the above solution, when the multiple filter screens 2 are in a horizontal state and located at the upper side wall 11, the edge of the filter screen 2 abuts against the upper side wall 11, and the filter screen 2 can complete the filtering work of the nano-color paste;

[0037] If the filter 2 needs to be replaced or unblocked, the disassembly mechanism directly drives the filter 2 upward to the top of the filter box 1, and then moves to the outside of the filter box 1 to a position away from the filter box 1, so as to facilitate the replacement or unblocking of the filter 2.

[0038] When multiple filter screens 2 are located at the lower side wall 12, the filter screens 2 are not against the lower side wall 12, and the filter screens 2 cannot perform filtering work at this time, but can complete their own deformation through the adjustment mechanism, so that all filter screens 2 are inclined, and the inclination angle is the same, so that the filter screens 2 act as stirring blades, and then the filter screens 2 are driven to rotate through the stirring mechanism to stir the nano color paste.

[0039] The disassembly mechanism includes an L-rod 31 fixed on the side wall of the filter box 1 , the free end of the L-rod 31 is fixedly connected to a lower sleeve 32 , an upper sleeve 33 is arranged above the lower sleeve 32 , and a U-shaped rod 34 is fixedly connected between the upper sleeve 33 and the lower sleeve 32 .

[0040] A threaded rod 35 is rotatably connected inside the U-shaped rod 34, and an internal threaded sleeve 36 is sleeved on the threaded rod 35 and threadedly connected thereto. A sliding rod 37 extending to the outside of the upper sleeve 33 is fixedly connected to the internal threaded sleeve 36, and a longitudinal sliding groove 38 is provided on the upper sleeve 33 for the sliding rod 37 to move up and down.

[0041] The upper sleeve 33 is provided with a transverse sliding groove 39 located at the upper end of the longitudinal sliding groove 38 and connected to the longitudinal sliding groove 38 . The sliding rod 37 is slidably adapted to the transverse sliding groove 39 .

[0042] The threaded rod 35 is driven by an external motor.

[0043] By adopting the above scheme, when the sliding rod 37 is located in the longitudinal sliding groove 38, the rotation of the threaded rod 35 can drive the internal threaded sleeve 36 and the sliding rod 37 to move up and down. When the sliding rod 37 moves to the transverse sliding groove 39 at the upper end of the longitudinal sliding groove 38, the sliding rod 37 can follow the rotation of the threaded rod 35 through the internal threaded sleeve 36, so that the sliding rod 37 moves into the transverse sliding groove 39.

[0044] One end of the slide rod 37 away from the internal threaded sleeve 36 is fixedly connected to an annular shaft 310 sleeved on the upper sleeve 33, and the annular shaft 310 is sleeved with an annular sleeve 311 rotatably connected thereto, and a horizontal plate 312 is fixedly connected to the annular sleeve 311, and one end of the horizontal plate 312 is rotatably connected to a vertical shaft 313 distributed vertically thereto, and the lower end of the vertical shaft 313 is fixedly connected to a regular polygonal base 314, and the filter screen 2 is rotatably connected to the surface of the regular polygonal base 314.

[0045] In use, if the slide bar 37 moves to the lower end of the longitudinal slide groove 38 and enters the gap between the lower sleeve 32 and the upper sleeve 33, the slide bar 37 and the internal threaded sleeve 36 can rotate along with the threaded rod 35, so that the slide bar 37 rotates in the gap between the lower sleeve 32 and the upper sleeve 33;

[0046] At the same time, the sliding rod 37 can drive the annular shaft 310 to rotate in the annular sleeve 311 .

[0047] like Figures 6 to 8 As shown, the adjustment mechanism includes a worm gear 41 rotatably connected to a regular polygonal base 314 and coaxially fixed to the filter screen 2, a load-bearing rod 42 is fixedly connected to the side wall of the regular polygonal base 314, a worm 43 meshing with the worm gear 41 is rotatably connected to the load-bearing rod 42, and a first gear 44 coaxially fixed to the worm 43.

[0048] By arranging the worm wheel 41 and the worm 43 to cooperate with each other, a self-locking function can be achieved for the filter screen 2 .

[0049] The lower surface of the regular polygonal base 314 is fixedly connected to a spring rod 45, the lower end of the spring rod 45 is fixedly connected to a bottom plate 46, the upper surface of the bottom plate 46 is fixed with a rack 47 meshing with the first gear 44, the lower surface of the bottom plate 46 is rotatably connected to a limit rod 48, and a vertical rod 49 corresponding to the limit rod 48 is vertically fixed to the bottom surface of the inner wall of the filter box 1.

[0050] By setting the vertical rod 49, the lowest position to which the limit rod 48, the bottom plate 46 and the rack 47 can move downward can be limited. When the rack 47 cannot move downward and the first gear 44 is still moving downward, the first gear 44 will rotate.

[0051] like Figure 1 and Fig. 9 As shown, the stirring mechanism includes a mounting groove 51 which is opened on the upper sleeve 33 and is interconnected with the longitudinal slide groove 38. A spring rod 52 is fixedly connected in the mounting groove 51. A clamping block 53 is fixedly installed at the lower end of the spring rod 52. The clamping block 53 extends into the gap between the upper sleeve 33 and the lower sleeve 32.

[0052] The side of the clamping block 53 away from the longitudinal slide groove 38 is inclined, and is inclined from top to bottom from the side away from the longitudinal slide groove 38 to the side close to the longitudinal slide groove 38 .

[0053] By setting the block 53, when the slide bar 37 is between the upper sleeve 33 and the lower sleeve 32, the slide bar 37 can only rotate in one direction. If the threaded rod 35 rotates in the opposite direction at this time, the slide bar 37 will be blocked by the block 53 and move upward along the longitudinal slide groove 38.

[0054] The upper end of the upper sleeve 33 is rotatably connected to a non-complete gear 54 coaxially fixed with the threaded rod 35 , and the upper end of the vertical shaft 313 is sleeved with a second gear 55 .

[0055] In use, when the second gear 55 moves downward to the same horizontal plane as the incomplete gear 54 , the incomplete gear 54 can mesh with the second gear 55 and drive the second gear 55 to rotate.

[0056] The working principle and use process of the present invention:

[0057] In the initial state, the plurality of filter screens 2 are in a horizontal state, and when they are located at the upper side wall 11, the edge of the filter screen 2 is against the upper side wall 11, and at this time, the nano-color paste is poured into the filter box 1 through the opening at the upper end thereof, and the filter screen 2 can complete the filtering work of the nano-color paste;

[0058] When the filter screen 2 needs to be replaced or unblocked, the external motor is started to drive the threaded rod 35 to rotate, and the threaded rod 35 can drive the internal threaded sleeve 36, the sliding rod 37, the annular shaft 310, the annular sleeve 311, the horizontal plate 312, the vertical shaft 313, the regular polygon base 314 and the filter screen 2 to move upward, so that the filter screen 2 moves upward to the top of the filter box 1, and the sliding rod 37 moves to the top of the longitudinal slot 38. At this time, the sliding rod 37 loses its restriction, and the sliding rod 37 and the internal threaded sleeve 36 will rotate with the threaded rod 35, allowing the sliding rod 37 to rotate into the horizontal slot 39. The sliding rod 37 drives the filter screen 2 to rotate to the outside of the filter box 1 through the annular shaft 310, the annular sleeve 311, the horizontal plate 312, the vertical shaft 313 and the regular polygon base 314, so that the staff can unblock or replace the filter screen 2;

[0059] When the nano-color paste needs to be stirred, the filter screen 2 is driven to move downward to the lower side wall 12 in the filter box 1 by rotating the threaded rod 35. The limit rod 48 gradually abuts against the upper end of the vertical rod 49 when following the filter screen 2 to move downward, so that the limit rod 48, the bottom plate 46 and the rack 47 cannot continue to move downward. At this time, the first gear 44 is still following the filter screen 2 to move downward. Since the first gear 44 and the rack 47 are meshed with each other, the first gear 44 will rotate and can drive the worm 43 coaxially fixed thereto to rotate accordingly. The worm 43 can drive the worm wheel 41 to rotate accordingly. The worm wheel 41 can drive the filter screen 2 coaxially fixed thereto to rotate accordingly, so that the filter screen 2 rotates in an inclined state.

[0060] At the same time, the sliding rod 37 moves downward to the gap between the upper sleeve 33 and the lower sleeve 32, and the sliding rod 37 and the internal threaded sleeve 36 can rotate with the threaded rod 35. While rotating, the sliding rod 37 can push the inclined surface of the block 53 to make the block 53 move upward without hindering the rotation of the block 53. At this time, the threaded rod 35 will not move up and down when the filter screen 2 rotates. At the same time, the second gear 55 has moved downward with the filter screen 2 to the same horizontal plane as the incomplete gear 54. The threaded rod 35 drives the incomplete gear 54 coaxially fixed therewith to rotate accordingly. The incomplete gear 54 can mesh with the second gear 55 to drive the second gear 55 to rotate accordingly. The second gear 55 can drive the inclined filter screen 2 to rotate through the vertical shaft 313 and the regular polygon base 314, so that the filter screen 2 stirs the nano-color paste.
