Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a mixing device for preparing printer ink, including a stirring tank 1, a cover plate 2 is fixedly installed at the upper port of the stirring tank 1, a motor 3 is fixedly installed on the upper surface of the cover plate 2, the output end of the motor 3 penetrates through the cover plate 2 and is fixedly connected to a stirring rod 5, several stirring blades 6 are fixedly connected to the side wall of the stirring rod 5, a discharge pipe 4 is fixedly installed at the lower port of the stirring tank 1, and further includes: A scraping structure 7 provided inside the stirring tank 1 for scraping the ink material adhered to the inside of the stirring tank 1; A compression structure 8 provided on the surface of the stirring rod 5 for blowing the ink material with a higher deposition concentration at the bottom of the stirring tank 1; An auxiliary structure 9 provided on the side wall of the stirring tank 1 for further diluting the ink deposited at the bottom.

When discharging, the scraping bar 708 can realize the scraping and discharging work of the viscous ink adhered to the inner wall of the stirring tank 1, improving the discharging rate of the ink, and to a certain extent improving the use performance of the mixing device. By setting the compression structure 8, it is convenient to blow air into the inner position of the discharge pipe 4 at the bottom of the stirring tank 1, avoiding the phenomenon of bottom sediment accumulation, and further improving the stirring efficiency of the ink. By setting the auxiliary structure 9, it is convenient to flexibly dilute the ink to be discharged at the bottom of the stirring tank 1, and further improving the effect of stirring and mixing the ink.

[0034] Specifically describe the specific settings and functions of its scraping structure 7, compression structure 8 and auxiliary structure 9 below.

[0035] As Figures 1 to 6 shown, the scraping structure 7 includes a chute 701 opened inside the stirring rod 5. A floating block 702 is slidably connected to the inner wall of the chute 701. The floating block 702 is in a cylindrical structure. Connecting rods 703 are fixedly connected to both sides of the floating block 702. The connecting rods 703 are slidably connected to the inner wall of the chute 701. The other end of the connecting rod 703 is fixedly connected to a scraping strip 708. The scraping strip 708 is in a V-shaped structure. The bottom inclined side of the scraping strip 708 is attached to the bottom side of the mixing tank 1. By setting the scraping strip 708 in a V-shaped structure, the scraping effect of the bottom side of the scraping strip 708 on the residual ink at the bottom of the mixing tank 1 is improved. Arc-shaped diversion grooves 709 are opened on both sides of the scraping strip 708. The diversion grooves 709 on both sides of the scraping strip 708 guide the scraped ink back to the mixing area. A pointed protrusion 710 is fixedly connected to the upper end of the floating block 702. The pointed protrusion 710 is in a conical structure. The setting of the pointed protrusion 710 facilitates the guiding work of the ink adhering to the upper side of the floating block 702 and avoids the phenomenon of ink accumulation on the upper surface of the floating block 702. A positioning block 704 is fixedly connected to the lower end of the scraping strip 708. A plurality of second rolling strips 707 are fixedly connected to the lower end of the positioning block 704. The second rolling strips 707 at the lower end of the positioning block 704 improve the stirring effect on the precipitated materials inside the discharge pipe 4. A filter plate 705 is fixedly connected to the inner side of the discharge pipe 4. A plurality of first rolling strips 706 are fixedly connected to the upper surface of the filter plate 705. The first rolling strips 706 and the second rolling strips 707 are arranged in an alternating manner. The second rolling strips 707 at the lower end of the positioning block 704 and the first rolling strips 706 on the filter plate 705 are alternately pressed to further break the particle aggregates in the ink and ensure fine discharge.

[0036] As Figures 1 to 2 and Figure 5 as well as Figure 7As shown, the compression structure 8 includes a number of folding tubes 84 connected to the top side of the stirring rod 5. The other end of the folding tube 84 is fixedly connected to a connecting block 85 of an L-shaped structure. The surface of the connecting block 85 is fixedly connected to a slider 87. The outer side of the slider 87 is slidably connected to a square tube 86. The square tube 86 is fixedly connected to the side wall of the stirring rod 5. The lower side of the cover plate 2 is fixedly connected to a circular ring 83. The circular ring 83 is located outside the stirring rod 5. The inner side of the circular ring 83 is fixedly connected to a number of protrusions 88. The protrusions 88 are of a right triangular prism structure. A number of through holes 81 communicating with the folding tubes 84 are provided on the lower side of the stirring rod 5. When the stirring rod 5 rotates, it drives the connecting block 85 and the folding tubes 84 to periodically approach or move away from the circular ring 83. When the folding tube 84 contacts the protrusions 88 on the inner side of the circular ring 83, the tube body is squeezed and deformed, and the internal air is sprayed to the bottom of the stirring tank 1 through the through holes 81. By repeatedly compressing the folding tubes 84, the deposited high-concentration ink material is dispersed, avoiding the accumulation of bottom precipitation. A first screen 82 is fixedly connected to the inner side of the through hole 81. The first screen 82 can filter the granular ink raw material at the position of the discharge pipe 4 of the stirring tank 1, avoiding the blockage at the position of the through hole 81.

[0037] As Figures 1 to 3 and Figure 8 shown, the auxiliary structure 9 includes a fixed tube 92 connected to the side wall of the stirring tank 1. The other end of the fixed tube 92 is connected and fixedly connected to a storage tank 91. A piston 93 is slidably connected to the inner side of the storage tank 91. The upper end of the piston 93 is fixedly connected to a limiting strip 96. The upper end of the storage tank 91 is fixedly connected to a fixed block 94. The limiting strip 96 and the fixed block 94 are slidably connected inside. A driving rod 95 is threadedly connected to the inside of the fixed block 94. The driving rod 95 and the inside of the piston 93 are rotatably connected. When it is necessary to dilute the pigment at the bottom side position of the stirring tank 1 before discharging, the piston 93 is pressed down, and the solvent in the storage tank 91 is injected into the bottom of the stirring tank 1 through the fixed tube 92. After the solvent is injected, with the air flow disturbance of the stirring blade 6 and the compression structure 8, the directional dilution and mixing of the bottom material can be realized. A second screen 97 is fixedly connected to the inner side of the port of the fixed tube 92 far from the storage tank 91. The second screen 97 can avoid the blockage during the process of the fixed tube 92 sucking the solvent.

[0038] Working principle: When the stirring rod 5 rotates, the floating block 702 slides along the chute 701 due to the buoyancy of the ink, drives the scraping strip 708 to move closely along the inner wall of the stirring tank 1 through the connecting rod 703. After starting the motor 3 and driving the stirring rod 5 to twist, the side of the scraping strip 708 continuously scrapes off the viscous ink adhered to the tank wall due to surging, and scrapes the viscous ink adhered due to surging back to the inside of the stirring tank 1 for re-stirring, thus avoiding the phenomenon that the ink material adhered to the inner side of the stirring tank 1 is not easy to stir. The diversion grooves 709 on both sides of the scraping strip 708 guide the scraped ink back to the stirring area. The setting of the pointed protrusion 710 facilitates the guiding work of the ink adhered to the upper side of the floating block 702, avoiding the phenomenon of ink accumulation on the upper surface of the floating block 702. When the ink is discharged through the discharge pipe 4, the second rolling strip 707 at the lower end of the positioning block 704 not only improves the stirring effect on the precipitated material inside the discharge pipe 4, but also the second rolling strip 707 at the lower end of the positioning block 704 and the first rolling strip 706 on the filter plate 705 are squeezed alternately, further crushing the particle aggregates in the ink, ensuring smooth discharge, avoiding the ink scraped from the bottom wall being relatively viscous, which is likely to reduce the discharge efficiency of the ink, and ultimately reducing the ink production quality. By setting the scraping strip 708 with a V-shaped structure, the scraping effect of the bottom side of the scraping strip 708 on the residual ink at the bottom wall of the stirring tank 1 is improved. The ink finally passes through the rolling and filtering of the filter plate 705 to output a uniform and stable ink product. By setting the connecting rod 703, it not only facilitates the stable connection of the scraping strip 708, but also facilitates the stirring work of the ink inside the stirring tank 1. The position of the lower inclined side of the scraping strip 708 also improves the stirring efficiency of the ink inside the stirring tank 1. By setting the scraping structure 7, it facilitates the scraping work of the viscous ink adhered to the inner wall of the stirring tank 1, can scrape it back to the stirring area during the working process, improves the stirring efficiency of the ink, and when discharging, the scraping strip 708 can realize the scraping and discharging work of the viscous ink adhered to the inner wall of the stirring tank 1, improving the discharging rate of the ink, and to a certain extent improving the use performance of the mixing device.

[0039] When the stirring rod 5 rotates, it drives the connecting block 85 and the folding tube 84 to approach or move away from the circular ring 83 periodically. When the folding tube 84 contacts the protrusion 88 inside the circular ring 83, the tube body is squeezed and deformed, and the internal air is sprayed to the bottom of the stirring tank 1 through the through hole 81. By repeatedly compressing the folding tube 84, the deposited high-concentration ink material is dispersed, avoiding the accumulation of bottom precipitation. The first screen 82 can filter the granular ink raw material at the position of the discharge pipe 4 of the stirring tank 1, avoiding the blockage of the through hole 81. The slider 87 slides along the square through 86, playing a role in restricting the telescopic direction of the folding tube 84, and thus avoiding the phenomenon of the folding tube 84 being bent during the compression process. By setting the compression structure 8, it facilitates the blowing work towards the inner side position of the discharge pipe 4 at the bottom side of the stirring tank 1, avoiding the accumulation of bottom precipitation, and further improving the stirring efficiency of the ink.

[0040] During the process of stirring the ink, by rotating the driving rod 95, the piston 93 is driven to move up and down in the storage tank 91. The second screen 97 can prevent the fixed pipe 92 from being blocked during the process of sucking the solvent, ensuring the purity of the sucked diluent, and enabling the extraction of part of the materials inside the stirring tank 1. When it is necessary to discharge the pigment at the bottom of the stirring tank 1 and dilute the sediment at the bottom, the piston 93 is pressed down, and the solvent in the storage tank 91 is injected into the bottom of the stirring tank 1 through the fixed pipe 92. After the solvent is injected, with the airflow disturbance of the stirring blade 6 and the compression structure 8, the directional dilution and mixing of the bottom materials can be achieved. By setting the auxiliary structure 9, the flexible dilution of the ink to be discharged at the bottom of the stirring tank 1 is facilitated, and the effect of stirring and mixing the ink is further improved.

[0041] The scraping structure 7 continuously cleans the tank wall, the compression structure 8 blows away the bottom sediment, and the auxiliary structure 9 accurately supplements the solvent. The three are linked with the stirring mechanism to form a three-dimensional mixing mode of "scraping the wall - blowing away - diluting", effectively solving the problems of sticky ink being prone to adhesion, precipitation, and uneven mixing.
