In the prior art, it can be achieved by a deflection electrode inkjet printer (for example, Chinese Invention Patent 201711063923.1), and the information to be identified is sprayed or engraved on the item. Due to internal working reasons of the rapid inkjet printers on the market, the ink temperature rises, and at the same time, the self-ink cooling effect is poor, affecting the use effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a rapid inkjet coding device for medicine box supervision codes, which can solve the deficiencies of the prior art and preferably solve the problem of ink cooling.

[0004] To solve the above technical problems, the technical solutions adopted by the present invention are as follows.

[0005] A rapid inkjet coding device for medicine box supervision codes includes a main body housing. There are rollers provided at the lower part of the main body housing, a handle provided at the end of the main body housing, and the main body housing and the handle are integrally formed. There is an ink spraying port provided at the bottom of the main body housing. Inside the main body housing, there is an ink delivery pipe communicating with the inside of the handle. The outlet end of the ink delivery pipe is provided with an inkjet preparation bin. There is a heating hole plate provided at the lower part of the inkjet preparation bin. A number of heating plate holes are vertically provided on the heating hole plate, and there are gaps between the heating plate holes and the bottom of the inkjet preparation bin. Two oppositely arranged power supply plates are connected to the lower part of the inkjet preparation bin. A droplet hole channel is formed between the two power supply plates. The two power supply plates are respectively connected to a square metal block and a wedge-shaped metal block through brackets. There is an ink spraying port provided at the bottom of the main body housing. There is a reflux pool provided on one side of the ink spraying port. A reflux pump pipe is connected to the side of the reflux pool. The reflux pump pipe is connected to a reflux elbow through a reflux pump. The reflux elbow extends into the handle and is connected to a reflux vertical pipe. A number of cooling brushes for promoting the cooling of ink droplets are provided inside the handle, and the cooling brushes are arranged in a vertically staggered manner in sequence inside the handle.

[0006] Preferably, the cooling brush includes a cooling brush rod. A number of turntable bases are movably sleeved on the cooling brush rod. A driven disk is coaxially and fixedly connected to the top of the turntable base. Two grid main rods are fixedly connected to both sides of the driven disk. A number of mutually parallel cooling grids are fixed on the grid main rods. Two torsion springs are provided at the bottom edge of the turntable base. One end of each torsion spring is connected to the turntable base, and the other end is connected to the cooling grid fixed on the adjacent grid main rod below.

[0007] Preferably, the cooling grille is horizontally provided with cooling plate slope grooves, the depth of the cooling plate slope grooves gradually decreases from one end to the other end, and the bottom of the cooling plate slope grooves is provided with slot holes penetrating through the cooling grille.

[0008] Preferably, an arc transition surface is provided at the end with a larger depth of the cooling plate slope groove, the other end of the cooling plate slope groove is in a closed state, and the arc transition surfaces belonging to the same grille main rod are located at the same end of the corresponding cooling plate slope groove.

[0009] Preferably, horizontal nozzles are provided on the side wall of the reflux vertical pipe, and vertical nozzles are provided at the end of the reflux vertical pipe.

[0010] Preferably, a roller rod is connected to the inner side of the roller, an inner guide wheel is connected to the inner side of the roller rod, a roller spring is sleeved on the outer side of the roller rod, the inner end of the roller spring is slidably pressed against the inner guide wheel, and the outer end of the roller spring is fixed on the inner wall of the body shell.

[0011] The beneficial effects brought by adopting the above technical solutions are as follows: In the present invention, the ink flows into the lower part of the heating orifice plate through the heating orifice plate. The heating orifice plate heats the ink to cause cavity expansion, and the ink in the lower part of the heating orifice plate is squeezed into the ink droplet orifice channel in the middle of the energizing plate. The ink droplets are energized in the ink droplet orifice channel to form charged ink droplets, and have an initial velocity. When the charged ink droplets with an initial velocity move downward through between the square metal block and the wedge-shaped metal block, an electric field is formed between the square metal block and the wedge-shaped metal block, causing the charged ink droplets to deflect. When ink droplet marking is not required in the printing gap, the energizing plate does not energize the ink droplets. A reflux pool is provided vertically below the ink droplet orifice channel, which can recover the ink droplets that are not energized but have a high temperature. The reflux pool is connected to a reflux pump, and the reflux pump pressurizes and injects the recovered ink droplets into the reflux elbow pipe, and finally into the handle. The cooling brush in the inner cavity of the handle can block and decompose the high-temperature ink from the reflux pool, and better utilize the original low-temperature ink to cool the high-temperature ink.

[0022] Refer to Figures 1-9, A specific embodiment of the present invention includes a main body housing 1. There are rollers 2 provided at the lower part of the main body housing 1, and a handle 3 is provided at the end of the main body housing 1. The main body housing 1 and the handle 3 are integrally formed. There is a nozzle 4 provided at the bottom of the main body housing 1. An ink delivery pipe 12 communicating with the inside of the handle is provided inside the main body housing 1. The outlet end of the ink delivery pipe 12 is provided with an inkjet preparation bin 11. There is a heating hole plate 19 provided at the lower part of the inkjet preparation bin 11. A number of heating plate holes 23 are vertically provided on the heating hole plate 19. There is a gap between the heating plate holes 23 and the bottom of the inkjet preparation bin 11. Two oppositely arranged power supply plates 9 are connected to the lower part of the inkjet preparation bin 11. A droplet channel 24 is formed between the two power supply plates 9. The two power supply plates 9 are respectively connected to a square metal block 8 and a wedge-shaped metal block 13 through brackets 10. There is a nozzle 4 provided at the bottom of the main body housing 1. There is a return pool 21 provided on one side of the nozzle 4. A return pump pipe 22 is connected to the side of the return pool 21. The return pump pipe 22 is connected to a return elbow 14 through a return pump 20. The return elbow extends into the handle 3 and is connected to a return vertical pipe 25. A number of cooling brushes 16 for promoting the cooling of ink droplets are provided inside the handle. The cooling brushes 16 are arranged in a staggered manner up and down in the handle 3 in sequence. In the present invention, the ink flows into the lower part of the heating hole plate 19 through the heating hole plate 19. The heating hole plate 19 heats up to cause the ink to expand with cavities, squeezing the ink in the lower part of the heating hole plate 19 into the droplet channel 24 between the power supply plates 9. The ink droplets are charged in the droplet channel 24 to form charged ink droplets and have an initial velocity. When the charged ink droplets with an initial velocity move downward through between the square metal block 8 and the wedge-shaped metal block 13, they are deflected under the action of the electric field. When ink droplet marking is not required during the printing interval, the power supply plates do not charge the ink droplets. A return pool 21 is provided vertically below the droplet channel. It can recover the ink droplets that are not charged but have a high temperature. The return pool is connected to a return pump 20. The return pump 20 pressurizes and injects the recovered ink droplets into the return elbow 14, and finally enters the handle 3. The cooling brushes 16 in the inner cavity of the handle 3 can block and decompose the high-temperature ink from the return pool 21, and better utilize the original low-temperature ink to cool the high-temperature ink. The inner side of the roller 2 is connected to a roller rod 5. The inner side of the roller rod 5 is connected to an inner guide wheel 17. The outer side of the roller rod 5 is sleeved with a roller spring 7. The inner end of the roller spring 7 is in sliding press contact with the inner guide wheel 17. The outer end of the roller spring 7 is fixed on the inner wall of the main body housing 1. There are rollers 2 for positioning provided at the lower part of the main body housing 1. According to the width of the medicine box, the tightness of the roller spring 7 inside the roller 2 can be automatically adjusted to accurately position the inkjet position.

[0023] The cooling brush 16 includes a cooling brush rod 26, on which a number of turntable bases 28 are movably sleeved. A driven disk 30 is coaxially and fixedly connected to the top of the turntable base 28. On both sides of the driven disk 30, grille main rods 33 are fixedly connected. A number of mutually parallel cooling grilles 32 are fixed on the grille main rods 33. At the bottom edge of the turntable base 28, two torsion springs 31 are arranged. One end of the torsion spring 31 is connected to the turntable base 28, and the other end is connected to the cooling grille 32 fixed on the adjacent grille main rod 33 below. The number of turntable bases movably sleeved on the cooling brush rod 26 are connected to the driven disk 30. When the cooling brush 16 is impacted by high-temperature ink, it starts to rotate. Since the ink flow rates at different positions are not exactly the same, the rotation directions and angles of different turntable bases 28 will be different. The rotation drives the torsion spring 31 to stretch and contract, and the torsion spring 31 pulls the next-layer turntable base 28 to rotate together, but the rotations are not synchronous. Such variable-speed rotation causes the hot and cold inks to form a turbulent layer at different heights. The fluids between the turbulent layers rub against each other, which also causes the fluids in the contact surface to roll, increasing the heat exchange and improving the cooling effect.

[0024] The cooling grille 32 is horizontally provided with a cooling plate slope groove 27, and the depth of the cooling plate slope groove 27 gradually decreases from one end to the other end. A slot hole 6 penetrating the cooling grille 32 is arranged at the bottom of the cooling plate slope groove 27. When the cooling grille 32 has a rotation angle, the ink will flow along the cooling plate slope groove 27 in the direction of the rotation of the cooling grille 32. The cooling plate slope groove 27 causes different flow rates on both sides of the cooling grille 32. Different flow rates generate a pressure difference, and the pressure difference will press the ink on the side with high pressure into the side with low pressure through the slot hole 6, generating cross convection at the slot hole 6 and further optimizing the cooling effect.

[0025] An arc transition surface 29 is arranged at the end with a larger depth of the cooling plate slope groove 27, and the other end of the cooling plate slope groove 27 is in a closed state. The arc transition surfaces 29 belonging to the same grille main rod 33 are located at the same end of the corresponding cooling plate slope groove 27. When the cooling grille 32 rotates towards the side of the arc transition surface 29, the ink flows towards the arc transition surface 29 through the cooling plate slope groove 27, forming a smooth flow area; when the cooling grille 32 rotates towards the other side, the ink flows towards the closed end of the cooling plate slope groove 27, and the ink flow is blocked at the closed end, forming a local turbulent area. Since the rotation directions and angles of different turntable bases 28 are different, the ink states at both ends of different cooling grilles 32 are not the same, which further disturbs the ink flow state in the entire inner cavity of the handle 3, and then keeps the rotation directions of different cooling grilles 32 out of sync. Under the action of this positive feedback disturbance, the ink in different regions will always maintain an obvious turbulent state, thus ensuring the cooling effect of the ink.

[0026] The side wall of the vertical return pipe 25 is provided with a horizontal nozzle 15, and a vertical nozzle 18 is provided at the end of the vertical return pipe 25. The horizontal nozzle sprays pressurized ink onto the cooling brush 16, and the vertical nozzle 18 sprays ink downward, which can generate different degrees of disturbance to the horizontally sprayed ink at different positions in the initial state, so as to realize the preliminary turbulent state of the ink in the inner cavity of the handle 3.

[0027] The working principle of the invention is as follows: According to the width of the medicine box, the tightness of the roller spring 7 inside the roller 2 can be automatically adjusted to accurately position the inkjet position. Ink is poured into the handle, and the ink flows into the inner part of the body shell to the left due to the action of gravity. The ink flows through the heating orifice plate 19 and into the lower part of the heating orifice plate 19. The heating orifice plate 19 heats the ink to cause cavity expansion, and the ink in the lower part of the heating orifice plate 19 is squeezed into the ink droplet orifice channel 24 in the middle of the energizing plate 9. The ink droplets are energized in the ink droplet orifice channel 24 to form charged ink droplets, and have an initial velocity. When the charged ink droplets with an initial velocity move downward through between the square metal block 8 and the wedge-shaped metal block 13, they are deflected under the action of the electric field. When the printing gap does not require ink droplet marking, the energizing plate does not energize the ink droplets. A return pool 21 is provided vertically below the ink droplet orifice channel, which can recover the ink droplets that are not energized but have a high temperature. The return pool is connected to a return pump 20, and the return pump 20 pressurizes the recovered ink droplets and injects them into the return elbow 14, and finally enters the handle 3. The cooling brush 16 in the inner cavity of the handle 3 can block and decompose the high-temperature ink from the return pool 21, and better utilize the original low-temperature ink to cool the high-temperature ink. A return pool is provided vertically below the ink droplet orifice channel. The return pool is connected to a return pump 20, and the return pump 20 pressurizes the recovered ink droplets and injects them into the return elbow 14, and finally enters the handle 3. The cooling brush 16 in the inner cavity of the handle 3 can block and decompose the high-temperature ink from the return pool 21.
