Description

Technical Field

[0001] The present invention relates to the field of printing ink mixing equipment, and in particular to an ink mixing equipment for water-based printing. Background Art

[0002] Water-based printing is an environmentally friendly printing method that uses water as the dispersion medium of the ink. Compared with traditional solvent-based inks, water-based inks have a lower content of volatile organic solvents, so they are more environmentally friendly and less harmful to human health and the environment. With the increasing global awareness of environmental protection, water-based printing technology has gradually been widely promoted and applied. And the ink mixing equipment for water-based printing is an indispensable part of the water-based printing process. Although with the progress of technology, the drying speed of water-based inks has been significantly improved, but under normal conditions, its drying speed is still slower than that of solvent-based inks, which will affect the printing efficiency in application scenarios that require rapid drying. Summary of the Invention

[0003] In order to improve the problem that the drying speed is slow and affects the printing efficiency when the existing ink mixing equipment for water-based printing mixes water-based inks, the present invention provides an ink mixing equipment for water-based printing.

[0004] An ink mixing equipment for water-based printing provided by the present invention adopts the following technical solutions:

[0005] An ink mixing equipment for water-based printing includes a support frame. A plurality of extraction mechanisms are arranged on the top of the support frame. Signal lights are arranged on one side of each of the plurality of extraction mechanisms. Solvent boxes for storing auxiliary solvents are arranged on the other side of the plurality of extraction mechanisms and located on the other side of the signal lights. A plurality of material buckets are arranged on one side of the support frame relative to the plurality of extraction mechanisms. Output valves are arranged on the tops of the plurality of material buckets. The plurality of output valves are respectively connected to the plurality of extraction mechanisms through pipelines one by one;

[0006] A stirring mechanism is arranged on one side of the end of the support frame far from the extraction mechanism. A stirring cavity is formed in the inner wall of the stirring mechanism. A stirring barrel is rotatably arranged in the stirring cavity. A support rod is fixedly arranged in the middle of the stirring barrel, and the top of the support rod is rotatably connected to the top of the inner wall of the stirring cavity. A servo motor is fixedly arranged on the top of the stirring mechanism. The output end of the servo motor penetrates through the stirring mechanism and is located in the stirring cavity, and is fixedly connected to the top of the stirring barrel. An oil inlet for inputting red drying oil is formed through one side of the inner surface of the stirring barrel.

[0007] On one side of the side surface of the support frame where multiple extraction mechanisms are located, fixed frames are fixedly installed. At the bottom of multiple fixed frames, mixing barrels are fixedly installed. On one side of multiple mixing barrels, input pipes that are connected to the multiple extraction mechanisms one by one are arranged. On the other side of multiple mixing barrels relative to the input pipes, output pipes are connected. The output pipes extend in the pipeline groove and are docked with the access end of the stirring mechanism. A groove is inwardly formed on the front surface of the stirring mechanism, and a weighing mechanism for measuring weight is arranged in the groove.

[0008] By adopting the above technical solutions, the extraction mechanism is installed on the surface of the support frame to improve stability. The extraction mechanism extracts and mixes the material barrel and the solvent box. Finally, the mixed pigment is transported to the stirring barrel through the output pipe. The stirring barrel is connected to the servo motor through the support rod, so that the output end of the servo motor drives the stirring barrel to rotate, thereby mixing the ink inside the stirring barrel. During the ink mixing process, the stirring barrel transports the red drying oil for ink drying to the inside through the oil inlet to mix with the ink, thereby accelerating the drying process of the ink. And with the continuous rotation of the stirring barrel, the red drying oil is in a continuous and slow inflow state, forming the stability of ink mixing.

[0009] Preferably, a communication groove is penetrated and formed at the position of the oil inlet on the inner wall of the stirring mechanism, and an oil box for storing drier is fixedly installed at the position of the communication groove on the outer surface of the stirring mechanism.

[0010] By adopting the above technical solutions, the stirring barrel rotates, so that the oil inlet is aligned with the communication groove, forming a state of docking the inside of the stirring barrel with the oil box. Then, the drier in the oil box flows into the stirring barrel to mix with the ink, thereby accelerating the drying speed of the ink.

[0011] Preferably, heating wires for heating temperature are fixedly installed around the inner surface of the stirring barrel. An inclined surface is arranged on the bottom surface of the stirring barrel, and multiple stirring rods are fixedly installed around the support rod on the inclined surface.

[0012] By adopting the above technical solutions, the heating wires heat the ink in the stirring barrel, so that the internal moisture is discharged, accelerating the ink drying process. At the same time, the inclination of the inclined surface facilitates the discharge of the ink.

[0013] Preferably, an installation groove is formed in the middle of the support rod of the stirring barrel. The installation groove penetrates through the outer surface of the support rod and communicates with the inside of the stirring barrel. The installation groove extends along the top of the support rod, and an electric push rod is fixedly installed at the extending opening.

[0014] By adopting the above technical solutions, the installation groove penetrates the support rod and communicates with the stirring barrel, thereby providing a discharge channel for the discharge of the ink in the stirring barrel. At the same time, the electric push rod arranged in the installation groove extends, thereby controlling the opening and closing of the discharge channel.

[0015] Preferably, a telescopic rod is inserted and arranged in the installation groove at the bottom of the electric push rod, a through hole is provided at the center of the telescopic rod, and an opening and closing groove is provided on the inner wall of the through hole at the position where the installation groove passes through the support rod.

[0016] By adopting the above technical solution, the electric push rod drives the telescopic rod to move up and down, so that the penetration position of the opening and closing groove overlaps with the installation groove, which is convenient for controlling the connection between the stirring barrel and the installation groove, so that the ink can be discharged in a controllable manner.

[0017] Preferably, a discharge port is fixedly provided on the surface of the stirring mechanism above the weighing mechanism, the outlet of the discharge port is facing the surface of the weighing mechanism, and the bottom of the mounting groove passes through the stirring mechanism and is connected with the discharge port.

[0018] By adopting the above technical solution, the outlet end of the discharge port is aligned with the surface of the weighing mechanism, so that the stirred ink is discharged to the surface of the load-bearing mechanism for load-bearing. At the same time, the bottom of the installation groove is connected to the discharge port, so that the stirred ink can be transported to the outside through the discharge port.

[0019] Preferably, an air outlet hole is provided on the inner wall of the stirring chamber at the other side of the connecting groove, and the air outlet hole penetrates the outer surface of the stirring mechanism and is connected with the outside.

[0020] By adopting the above technical solution, the air outlet is connected to the outside. When the heating wire is running, the ink in the stirring chamber is heated by high temperature to discharge water and generate gas, so that the gas is discharged to the outside through the air outlet.

[0021] Preferably, a pipeline groove is provided in the middle of the surface of the support frame, and the position of the support frame at the end of the pipeline groove is connected to the stirring mechanism.

[0022] By adopting the above technical solution, the opening of the pipeline groove reserves installation space for multiple output pipes, and at the same time the end of the pipeline groove is connected to the stirring mechanism, so as to facilitate the connection of the multiple output pipes with the stirring mechanism.

[0023] Preferably, an operation interface for regulating the stirring mechanism is provided on the side surface of the stirring mechanism located on the top of the weighing mechanism.

[0024] By adopting the above technical solution, the operation interface is used to control the stirring rate of the stirring mechanism, and to display the data of the stirring mechanism and to feedback the weight data measured by the weighing mechanism.

[0025] Preferably, the tops of the plurality of barrels are connected to one side of the output valves and are each provided with an input port for introducing pigment.

[0026] By adopting the above technical solution, the input port is connected to the external introduction mechanism, so that the pigment is transported to the barrel for storage.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. By continuously rotating the stirring barrel, the communication groove is aligned with the oil inlet, and the red drying oil in the oil box is conveyed into the stirring barrel. At the same time, with the heating wire arranged around the inside of the stirring barrel, the temperature in the stirring cavity is increased, accelerating the drying process of the ink, thereby improving the printing efficiency;

[0029] 2. With the communication groove and the oil inlet being intermittently aligned, as the stirring barrel rotates, the red drying oil in the oil box intermittently flows into the stirring barrel to be mixed with the ink. When the communication groove and the oil inlet are staggered, the oil box is in a closed state, keeping the amount of red drying oil stable and forming a continuous input state. While ensuring the accelerated drying effect, it prevents the formation of crust on the ink roller of the printing machine due to excessive use of red drying oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A plurality of barrels 5 are placed at the bottom of the side of the support frame 1 away from the solvent box 3 (the number of barrels 5 is the same as that of the extraction mechanism 2), and pigments for ink mixing are stored in the barrels 5. At the same time, an input port 8 is provided at the top of the barrel 5, and the input port 8 is connected to an external pigment supply device. An output valve 7 is provided again on one side of the connection between the input port 8 and the barrel 5, and the output valve 7 is connected to the barrel 5, and the output end of the output valve 7 is connected to the input end on one side of the extraction mechanism 2 through a pipeline.

[0045] Reference Figure 1 , Figure 2 , Figure 3 A plurality of fixing frames 4 are fixed by screws on the surface of one side of the support frame 1 close to the material barrel 5 (the number of the fixing frames 4 is the same as the material barrel 5), and the plurality of fixing frames 4 are all L-shaped, and the lower end surface of the L-shaped bend can be detachably connected with a mixing barrel 9, and an input end of one side of the top of the mixing barrel 9 is docked with an input pipe 11, and the end of the input pipe 11 away from the mixing barrel 9 is docked with the input end of the extraction mechanism 2, and a stirring mechanism 6 is placed at the extended end of the support frame 1, and the input end of the stirring mechanism 6 is aligned with the pipeline groove 29, and an output pipe 10 is docked on the side of the mixing barrel 9 away from the input pipe 11, and the end of the output pipe 10 away from the mixing barrel 9 extends from the pipeline groove 29 and docks with the input end of the stirring mechanism 6, and an operation interface 17 is provided on the front end surface of the stirring mechanism 6, and a groove is provided inwardly on the front end surface of the stirring mechanism 6 below the operation interface 17, and a weighing mechanism 16 for weighing is fixed in the groove.

[0046] It should be noted that the operation interface 17 includes structures such as a screen, a keyboard, and a display screen for displaying the feedback data of the weighing mechanism 16. At the same time, a discharge port 15 is fixedly provided on one side of the inner wall of the groove of the stirring mechanism 6, and the output end of the discharge port 15 is aligned with the weighing end of the weighing mechanism 16.

[0047] The fixing frame 4 is screwed to the support frame 1 to form a fixation, and the mixing barrel 9 is fixedly connected inside the fixing frame 4, forming an overall fixation of the mixing barrel 9 and the support frame 1 to improve stability. At the same time, one end of the mixing barrel 9 receives the auxiliary solvent and pigment conveyed by the extraction mechanism 2 through the input pipe 11 and temporarily stores them in the mixing barrel 9 for preliminary mixing, and then is conveyed to the stirring mechanism 6 through the output pipe 10 for unified mixing with the remaining pigments. The ink after stirring is discharged from the discharge port 15 and falls into the storage box placed on the surface of the weighing mechanism 16, and the weighing mechanism 16 weighs the storage box and the ink inside and feeds the data back to the operation interface 17.

[0048] Refer to Figure 3 、 Figure 4 、 Figure 5 As shown in, a servo motor 13 is fixedly provided at the top of the stirring mechanism 6. The output end of the servo motor 13 movably penetrates the inside of the stirring mechanism 6. And a cylindrical stirring cavity 30 is opened at the penetration position of the servo motor 13 inside the stirring mechanism 6. A stirring barrel 18 is movably abutted against the inner surface of the stirring cavity 30. The bottom of the stirring barrel 18 is in a barrel shape, and a support rod is fixedly provided in the middle of the barrel shape. The top of the support rod is fixedly connected to the end of the penetrating end of the servo motor 13. The barrel height of the stirring barrel 18 is 3 - 4 cm lower than the inside of the stirring cavity 30. And an air outlet hole 21 is opened at a position inside the stirring cavity 30 higher than the stirring barrel 18. The air outlet hole 21 penetrates the outer surface of the stirring mechanism 6 and communicates with the outside. On the other side of the inner wall of the stirring cavity 30 relative to the air outlet hole 21 and at a position covered by the stirring barrel 18, a communication groove 22 is opened. The communication groove 22 penetrates the outer surface of the stirring mechanism 6 and communicates with the outside.

[0049] It should be noted that a plurality of nozzles are arranged around the support rod at the top of the inner wall of the stirring cavity 30. The nozzles are docked with a plurality of output pipes 10. An oil box 14 is fixedly provided on the outer surface of the stirring mechanism 6 at the position of the communication groove 22. The oil box 14 stores red drying oil for assisting in drying the ink. The output end of the oil box 14 is inserted into the communication groove 22 to form a docking. At the same time, an oil inlet 19 is penetrated at the position of the communication groove 22 on the outer surface of the stirring barrel 18. The width of the oil inlet 19 is the same as that of the communication groove 22 and is centered and aligned. A heating wire 20 for heating is fixedly provided around the inner surface of the stirring barrel 18.

[0050] The output end of the servo motor 13 rotates and is integrally fixed by being fixedly connected to the support rod at the top of the stirring barrel 18, thereby driving the entire stirring barrel 18 to rotate. As the stirring barrel 18 rotates, the communication groove 22 and the oil inlet 19 are continuously aligned. When the communication groove 22 is aligned with the oil inlet 19, the red drying oil in the oil box 14 flows into the stirring barrel 18 along the oil inlet 19 and mixes with the ink. When the communication groove 22 and the oil inlet 19 are staggered, the inflow of the red drying oil in the oil box 14 is prevented, and the alignment time of the oil inlet 19 and the communication groove 22 accounts for 3-4% of the total rotation ratio of the stirring barrel 18. Thus, during the stirring process of the ink, the red drying oil keeps flowing slowly into the ink while preventing excessive inflow. When the ink is being stirred, the heating wire 20 in the stirring barrel 18 performs auxiliary heating to accelerate the drying speed of the ink, and the gas generated by heating the ink rises and is discharged to the outside along the air outlet 21.

[0051] Refer to Figure 6 、 Figure 7 、 Figure 8 The bottom of the barrel-shaped stirring barrel 18 is inclined towards the support rod to form an inclined surface 24. A plurality of stirring rods 23 are fixedly arranged around the surface of the inclined surface 24. An installation groove 28 is opened upward from the bottom of the stirring barrel 18 through the support rod. The bottom of the installation groove 28 is connected and communicated with the discharge port 15 through a pipeline. The position of the installation groove 28 at the bottom of the inclined surface 24 penetrates through the support rod to form a connection with the inside of the barrel. At the same time, an electric push rod 27 is fixedly arranged at the top of the installation groove 28. The output end of the electric push rod 27 extends downward and is fixedly connected with a telescopic rod 25. The telescopic rod 25 moves up and down as a whole within the installation groove 28, and a through hole is opened upward at the bottom of the telescopic rod 25. An opening and closing groove 26 with the same width is opened at the through hole of the installation groove 28. Under normal conditions, the opening and closing groove 26 and the through hole of the installation groove 28 are staggered, so that the through hole of the installation groove 28 is in a closed state.

[0052] The output end of the electric push rod 27 extends to drive the telescopic rod 25 to move downward along the installation groove 28. As the telescopic rod 25 moves, the opening and closing groove 26 coincides with the through hole of the installation groove 28, thereby changing the through hole of the installation groove 28 to an open state. Then, the ink in the stirring barrel 18 flows into the installation groove 28 along the inclined surface of the inclined surface 24, forming the opening and closing control of the installation groove 28. At the same time, as the stirring barrel 18 rotates, the plurality of stirring rods 23 rotate and contact the ink, thereby stirring and mixing the ink.

[0053] The implementation principle of an ink mixing device for water-based printing in an embodiment of the present invention is as follows: When using this device, personnel first pour the auxiliary solvent to be formulated into the solvent box 3, then dock the solvent box 3 with the access port at one end of the extraction mechanism 2, and then fill multiple paint buckets 5 with pigments through multiple input ports 8 in sequence. Then, as personnel operate the operation interface 17 to control the operation of the extraction mechanism 2, the extraction mechanism 2 extracts from the paint buckets 5 and the solvent box 3 respectively, and conveys the extracted auxiliary solvent and pigments to the mixing bucket 9 through the input pipe 11. During the conveying process, the auxiliary solvent and pigments are preliminarily mixed, and when temporarily stored in the mixing bucket 9, the mixture is made sufficient by standing still;

[0054] Then, the stirring mechanism 6 extracts the pigments in the mixing bucket 9 through the output pipe 10 and discharges them into the stirring cavity 30 through multiple nozzles. The various pigments discharged into the stirring cavity 30 fall into the stirring bucket 18. During the pigment discharging process, personnel control the operation of the servo motor 13 through the operation interface 17. The output shaft of the servo motor 13 drives the support rod to rotate, and the support rod drives the entire stirring bucket 18 to rotate within the stirring cavity 30, so that multiple stirring rods 23 stir the falling pigments.

[0055] As the stirring bucket 18 continues to rotate, when the oil inlet 19 is aligned with the communication groove 22, the red drying oil in the oil box 14 flows into the stirring bucket 18 through the oil inlet 19 and stirs with the mixed printing ink, thereby accelerating the drying of the printing ink. At the same time, as the stirring bucket 18 rotates, the heating wire 20 on the inner wall of the stirring bucket 18 operates to generate heat, causing the temperature inside the stirring bucket 18 to rise, cooperating with the red drying oil to accelerate the drying speed of the printing ink. At the same time, the gas generated by the rising temperature of the printing ink is discharged to the outside through the air outlet 21;

[0056] When the printing ink is stirred and left to stand for a period of time, the telescopic end of the electric push rod 27 contracts, driving the telescopic rod 25 to move upward along the installation groove 28. As the telescopic rod 25 moves, the opening and closing groove 26 is aligned with the through port of the installation groove 28, thereby making the through port of the installation groove 28 in an open state. At this time, due to the inclined setting of the inclined surface 24, the printing ink flows towards the position at the bottom of the support rod and finally flows into the discharge port 15 through the installation groove 28 and is discharged into the storage box placed on the surface of the weighing mechanism 16. At this time, the weighing mechanism 16 weighs the discharged printing ink and feeds back the data for the convenience of personnel formulation.

[0057] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
