[0002] Ink is a uniform mixture of colored bodies, binders, fillers, additives, etc. It can be printed and dried on the printed object. It is a colored, fluid slurry adhesive. There are many types of inks with different physical properties. Some are very thick and sticky, while others are quite thin. These are determined by the object of printing, i.e. the substrate, the printing method, the type of printing plate, and the drying method.

[0003] In the prior art, when preparing printing ink, the raw materials need to be poured into the interior of the tank for stirring and mixing. However, the stirring paddle of the existing ink preparation tank is generally not in contact with the inner wall of the tank. This is to avoid the friction between the stirring paddle and the inner wall of the tank during stirring, which hinders the operation of the stirring paddle and thus affects the stirring efficiency. However, when cleaning, water is poured into the tank and then the water in the tank is stirred by the stirring paddle to clean the tank. Since the stirring paddle has no contact with the inner wall, the cleaning efficiency of the side wall of the tank is not high. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figure 1-Figure 7 The present embodiment provides an ink preparation tank, comprising a tank body 1, an infusion tube 101 is installed on the top of the tank, a main shaft 2 is rotatably connected in the tank body 1, a plurality of rows of first stirring blades 3 and a plurality of vertically arranged second stirring blades 4 are arranged in a ring array on the outer periphery of the main shaft 2, and each row of first stirring blades 3 has a plurality of first stirring blades 3; each first stirring blade 3 is hinged to the main shaft 2 at one end, and hinged to the second stirring blade 4 at the other end; a rubber scraper 6 is installed on the side of the second stirring blade 4 away from the main shaft 2; a mounting plate 7 is slidably connected to the main shaft 2 above the first stirring blade 3; a connecting rod 5 is hinged on the top of each second stirring blade 4, and the end of the connecting rod 5 away from the second stirring blade 4 is hinged to the mounting plate 7; a first driving member 8 for driving the main shaft 2 to rotate is installed on the tank body 1, and a second driving member 9 for driving the mounting plate 7 to slide along the axis of the main shaft 2 is installed on the top of the main shaft 2.

[0025] The following is a further introduction in combination with specific usage scenarios. When preparing the ink, the ink raw materials are poured into the tank body 1 from the infusion tube 101, and the first driving member 8 is started to drive the first stirring blade 3, the second stirring blade 4 and the main shaft 2 to rotate synchronously, thereby stirring the ink raw materials. When the ink raw materials are stirred and mixed, the second stirring blade 4 and the rubber scraper 6 on the second stirring blade 4 will not contact the inner wall of the tank body 1. In this way, the inner wall of the tank body 1 will not hinder the overall rotation of the main shaft 2, the first stirring blade 3, the second stirring blade 4 and the rubber scraper 6, thereby ensuring the stability and smoothness of the ink configuration. When the inside of the tank body 1 needs to be cleaned, water is injected into the tank body 1, and then the second driving member 9 is started, and the mounting plate 7 is driven to move by the second driving member 9. It should be noted here that the angle between the connecting rod 5 and the second stirring blade 4 is an obtuse angle, and the angle between the first stirring blade 3 and the second stirring blade 4 is an acute angle. When the mounting plate 7 is controlled to move downward along the axis of the main shaft 2, the first stirring blade 3 can gradually become perpendicular to the main shaft 2, and then the second stirring blade 4 can gradually approach the inner wall of the tank body 1 until the rubber scraper 6 abuts against the inner wall of the tank body 1. Then the first driving member 8 is controlled to rotate so that when the main shaft 2 rotates, the first stirring blade 3, the second stirring blade 4 and the rubber scraper 6 will rotate synchronously around the main shaft 2, and the rubber scraper 6 will scrape the ink impurities on the inner wall of the tank body 1, and the water in the tank body 1 will flush the ink on the inner wall of the tank body 1 so that the ink on the inner wall of the tank body 1 is quickly cleaned, thereby improving the ink cleaning efficiency of the inner wall of the tank body 1.

[0026] On the whole, by arranging the main shaft 2, the first stirring blade 3, the second stirring blade 4, the rubber scraper 6, the first driving member 8, the second driving member 9 and the mounting plate 7, when preparing the ink, the rubber scraper 6 on the outside of the stirring paddle will not fit the side wall of the tank body 1, and when cleaning the tank body 1, the rubber scraper 6 on the outside of the stirring paddle will fit the tank body 1, which can ensure the stirring efficiency as a whole and improve the cleaning efficiency of the tank body 1.

[0027] Reference Figure 1 and Figure 2 As a specific implementation of the embodiment of the present application, the first driving member 8 includes a motor 81, a pulley 82 fixed to the shaft end of the motor 81 and fixed to the main shaft 2, and a belt 83 sleeved on the two pulleys 82.

[0028] In combination with specific usage scenarios, when stirring the ink raw materials or cleaning the inner wall of the tank body 1, the motor 81 is started, and the main shaft 2 is driven to rotate under the transmission of the belt 83 and the pulley 82, thereby stirring or cleaning the inner wall of the tank body 1.

[0029] Reference Figure 2 , Figure 3 and Figure 5As a specific implementation of the embodiment of the present application, the second driving member 9 adopts an electric telescopic rod, the main shaft 2 is provided with a cavity section 21 from the top, and a plurality of slide grooves 22 are provided in a ring array in the cavity section 21 of the main shaft 2; the mounting plate 7 includes a circular plate body 71 and a plurality of hinged columns 72, the plate body 71 is located inside the cavity section 21, and the hinged column 72 is located in the slide groove 22; the end of the connecting rod 5 away from the second stirring blade 4 is hinged with the hinged column 72.

[0030] In combination with specific usage scenarios, when the tank body 1 needs to be cleaned, the electric telescopic rod is started to drive the mounting plate 7 to move in the cavity section 21, and the mounting plate 7 will move with the connecting column, and the hinged columns 72 arranged in a ring array can ensure that there will be no circumferential movement during the sliding process of the mounting plate 7, thereby ensuring the stability of the driving of the first stirring blade 3 and the second stirring blade 4, and thus ensuring the stability of the stirring of the ink raw materials and the cleaning of the tank body 1.

[0031] Reference Figure 3 , Figure 6 and Figure 7 As a specific implementation of the embodiment of the present application, a dovetail groove 41 is opened on the side of the second stirring blade 4 close to the scraper, a trapezoidal strip 61 that fits the dovetail groove 41 is provided on the rubber scraper 6, and a limiting plate 62 is provided on the top of the rubber scraper 6.

[0032] In combination with specific usage scenarios, the cooperation of the dovetail groove 41 and the trapezoidal strip 61 can enable the rubber scraper to be replaced when it is damaged after long-term use, and can also increase the connection area between the scraper and the second stirring blade 4, thereby ensuring the installation stability of the rubber scraper 6, and thus ensuring the stability of the cleaning process. The limiting plate 62 is used to ensure that the rubber scraper 6 will not detach from the second stirring blade 4, further improving the installation stability between the second stirring blade 4 and the rubber scraper 6.

[0033] Reference Figure 2 As a specific implementation of the embodiment of the present application, bearings 10 are installed at the top and bottom of the outer periphery of the main shaft 2, and the main shaft 2 is rotatably connected to the tank body 1 through two bearings 10.

[0034] In combination with specific usage scenarios, bearings 10 are installed on the top and bottom of the main shaft 2 to achieve a rotational connection with the tank body 1. This can ensure the coaxiality of the rotation of the main shaft 2 and prevent radial movement, thereby improving the stability of the rotation of the main shaft 2 during the mixing of ink raw materials and the cleaning of the tank body 1, and improving the stability of the use of the configured tank.

[0035] Reference Figure 2 and Figure 3 As a specific implementation of the embodiment of the present application, a tension spring 11 is installed between two adjacent first stirring blades 3.

[0036] In combination with a specific usage scenario, by installing a tension spring 11 between two adjacent first stirring blades 3, not only can the connection stability between the first stirring blades 3 be increased, but also the vibration during stirring can be absorbed and the noise can be reduced.

[0037] Reference Figure 2 As a specific implementation of the embodiment of the present application, an annular water inlet pipe 102 is installed on the top of the tank body 1, and uniform water outlet holes are opened on the peripheral wall of the water inlet pipe 102.

[0038] In combination with specific usage scenarios, an annular water inlet pipe 102 is arranged on the top of the tank body 1, and the surrounding wall of the water inlet pipe 102 has uniform water outlet holes, so that during cleaning, the water column splashed through the water outlet can flush the inner wall of the tank body 1, which can not only clean the tank body 1 normally, but also save water resources; in addition, if water is directly injected into the tank body 1 for cleaning, during cleaning, the first stirring blade 3 and the second stirring blade 4 will also be subjected to the reaction force of water when they rotate, and the annular water inlet pipe 102 is installed on the top of the tank body 1, and the surrounding wall of the water inlet pipe 102 is provided with uniform water outlet holes, and the reaction force of water on the first stirring blade 3 and the second stirring blade 4 when they rotate will be greatly reduced, making the cleaning of the tank body 1 smoother.
