Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to an ink grinding device capable of cooling down. Background Technique

[0002] Ink is a liquid that can coat the surface of an object and form a continuous film firmly attached to the surface of the object to be coated. Ink is a viscous liquid prepared from resin, oil and emulsion as the main materials, adding corresponding additives, and using organic solvents or water.

[0003] Since the main materials and additives in the ink will form lumps after being placed for a long time, and the main materials and additives themselves will also form lumps, the ink cannot be used normally due to the existence of lumps inside, affecting the quality of the ink.

[0004] During the ink production and processing process, in order to uniformly mix the lumps in the ink with the ink, the processing personnel will use an ink grinding device to stir and grind the lumps. In order to grind the lumps in the ink, the ink with lumps will be placed into the grinding space of the ink grinding device. Grinding beads are arranged in the grinding space. The rotation of the stirring shaft drives the stirring rod connected to the stirring shaft to rotate in the grinding space, so that the grinding beads continuously impact the lumps under the stirring of the stirring rod, achieving the purpose of dispersing the lumps, and grinding the lumps to a predetermined size and mixing them into the ink to make the ink that meets the regulations.

[0005] In the existing ink grinding device, during the process of the stirring shaft driving the stirring rod to rotate in the grinding space, although the grinding beads will impact and disperse the lumps under the stirring of the stirring rod, however, the grinding beads will also impact the inner wall of the grinding space and the stirring shaft under the stirring of the stirring rod. The inner wall of the grinding space and the stirring shaft will heat up under the impact of the grinding beads, resulting in the temperature of the ink in the grinding space rising, and further causing the ink to deteriorate due to the temperature rise and thus unable to be used normally.

[0006] Secondly, when the temperature of the stirring shaft rises and then encounters ink with a temperature lower than that of the stirring shaft, it will cause the stirring shaft to crack when it gets cold, reducing the service life of the stirring shaft, and further leading to a decrease in the service life of the ink grinding device.

[0030] Reference Figures 1 to 7 , a temperature-lowering ink grinding device according to a preferred embodiment of the present utility model will be described in detail below, wherein the temperature-lowering ink grinding device includes a device main body 10, a grinding and stirring assembly 20, and a material feeding assembly 30.

[0031] The device main body 10 includes a device body 11 and a control member 12. The control member 12 is disposed on the device body 11.

[0032] The grinding and stirring assembly 20 includes a grinding main body 21, a plurality of grinding beads 22, and a grinding member 23. The grinding main body 21 is disposed on the device body 11. The grinding main body 21 forms a cooling space 2101 and a grinding space 2102. The cooling space 2101 is coaxially disposed on the outer periphery of the grinding space 2102, and there is a heat transfer protection layer between the cooling space 2101 and the grinding space 2102. A plurality of the grinding beads 22 are disposed in the grinding space 2102. The outer wall of the cooling space 2101 has a liquid inlet 2103 for introducing a cooling liquid and a liquid outlet 2104 for discharging the cooling liquid.

[0033] Preferably, the grinding beads 22 are implemented as zirconia beads.

[0034] The grinding member 23 includes a grinding driving member 231, a stirring shaft 232, a plurality of stirring rods 233, and a shaft fixing member 234. The grinding driving member 231 is disposed on the device body 11, and the grinding driving member 231 is electrically connected to the control member 12. One end of the stirring shaft 232 is coaxially connected to the grinding driving member 231 to achieve rotation through the grinding driving member 231. The stirring shaft 232 extends into the grinding space 2102. A plurality of the stirring rods 233 are evenly distributed around the outer periphery of the stirring shaft 232 in a surrounding manner. The other end of the stirring shaft 232 is rotatably fixed in the grinding space 2102 through the shaft fixing member 234.

[0035] Specifically, the material feeding assembly 30 includes a feeding member 31 and a discharging member 32. The feeding member 31 includes a feeding pipeline 311. One end of the channel formed by the feeding pipeline 311 communicates with the grinding space 2102, and the other end of the feeding pipeline 311 is disposed in a storage member 91 containing the ink to be ground. The feeding pipeline 311 is used to introduce the ink to be ground into the grinding space 2102. The discharging member 32 includes a suction pipeline 321 and a discharging suction member 322. The discharging suction member 322 is disposed on the device body 11, and the discharging suction member 322 is electrically connected to the control member 12. The two ends of the channel formed by the suction pipeline 321 communicate with the grinding space 2102 and the suction port of the discharging suction member 322 respectively. A discharging pipeline is connected to the flow outlet of the discharging suction member 322. That is to say, the discharging suction member 322 can suck out the ground ink in the grinding space 2102 through the suction pipeline 321 and discharge the ground ink into a predetermined storage barrel through the discharging pipeline.

[0036] It is worth mentioning that when the discharging suction member 322 is controlled by the control member 12 and sucks through the channel formed by the suction pipeline 321 into the grinding space 2102, a negative pressure environment will be formed in the grinding space 2102, and suction will be generated at the end of the channel formed by the feeding pipeline 311 communicating with the grinding space 2102 away from the grinding space 2102, thereby sucking the ink to be ground in the storage member 91 into the grinding space 2102 through the channel formed by the feeding pipeline 311.

[0037] Preferably, the discharging suction member 322 is implemented to include a suction pump.

[0038] Those skilled in the art can understand that after the ink to be ground in the storage member 91 is sucked into the grinding space 2102 through the channel formed by the feeding pipeline 311, the control member 12 will control the grinding driving member 231, and drive the stirring shaft 232 to rotate through the grinding driving member 231, so that the stirring rod 233 connected to the stirring shaft 232 stirs in the grinding space 2102, and drives the grinding beads 22 in the grinding space 2102 to stir in the grinding space 2102, so as to impact the agglomerates in the ink to be ground in the grinding space 2102 through the grinding beads 22, and disperse the agglomerates in the ink to be ground to a predetermined size through the impact of the grinding beads 22 and complete the grinding of the ink.

[0039] It is worth mentioning that during the process of the grinding beads 22 impacting the agglomerates in the ink to be ground, it is inevitable that the heat transfer protection layer between the grinding space 2102 and the cooling space 2101 will be impacted. Since the impact of the grinding beads 22 will cause the temperature of the heat transfer protection layer to rise, at this time, a cooling liquid is introduced into the cooling space 2101 through the liquid inlet 2103, and the heat transfer protection layer will transfer the heat to the cooling liquid in the cooling space 2101 through heat transfer.

[0040] Furthermore, the cooling liquid that absorbs heat and rises in the liquid inlet 2103 is discharged from the cooling space 2101 through the liquid outlet 2104, and a cooling liquid is continuously introduced into the cooling space 2101 through the liquid inlet 2103, so as to achieve the purpose of reducing the temperature of the heat transfer protection layer and avoid the ink in the grinding space 2102 from deteriorating due to the increase in the temperature of the heat transfer protection layer.

[0041] It should be noted that during the process of the grinding beads 22 impacting the agglomerates in the ink to be ground, the stirring shaft 232 will also be impacted, causing the stirring shaft 232 to heat up due to the impact. Since the stirring shaft 232 is made of metal, the high temperature of the stirring shaft 232 encountering the low temperature of the ink will cause cracks in the stirring shaft 232, thereby reducing the service life of the stirring shaft 232.

[0042] In this embodiment, a heat absorption space 23201 is formed at the axis of the stirring shaft 232 along the extending direction, and a cooling liquid is provided in the heat absorption space 23201. To absorb the heat of the stirring shaft 232 through the cooling liquid in the heat absorption space 23201 and avoid the heating of the stirring shaft 232.

[0043] Those skilled in the art can understand that when the stirring shaft 232 is used for a long time, the cooling liquid in the stirring shaft 232 will heat up due to absorbing a large amount of heat and cannot absorb the heat of the stirring shaft 232.

[0044] Preferably, the ink grinding device capable of cooling further includes a grinding cooling assembly 40. The grinding cooling assembly 40 is used to cool the coolant in the 23202.

[0045] In this embodiment, the grinding cooling assembly 40 includes a cooling member 41, a first flow pipe 42 and a second flow pipe 43. The cooling member 41 includes a cooling element 411, a cooling suction element 412 and a connecting pipe 413. Both the cooling element 411 and the cooling suction element 412 are disposed on the device body 11. The cooling suction element 412 is electrically connected to the control element 12. The cooling element 411 has a flow space 41101 and a cooling space 41102. The cooling space 41102 is coaxially disposed on the outer periphery of the flow space 41101, and there is a heat transfer layer between the flow space 41101 and the cooling space 41102. The outer wall of the cooling space 41102 forms an inlet 41103 for introducing a cooling liquid into the cooling space 41102 and an outlet 41104 for discharging the cooling liquid. The cooling suction element 412 has a suction port and a discharge port. The suction port of the cooling suction element 412 is communicated with the lower end of the flow space 41101 through the channel formed by the connecting pipe 413. One end of the channel formed by the first flow pipe 42 is communicated with one end of the heat absorption space 23201, and the other end of the channel formed by the first flow pipe 42 is communicated with the discharge port of the cooling suction element 412. One end of the channel formed by the second flow pipe 43 is communicated with the other end of the heat absorption space 23201, and the other end of the channel formed by the first flow pipe 42 is communicated with the upper end of the flow space 41101.

[0046] It should be noted that when the stirring shaft 232 rotates, the first flow pipe 42 and the second flow pipe 43 will break following the rotation of the stirring shaft 232.

[0047] Preferably, the grinding cooling assembly 40 further includes two connecting members 44. One of the connecting members 44 is disposed between the channel formed by the first flow pipe 42 and one end of the heat absorption space 23201 to prevent the first flow pipe 42 from being damaged following the rotation of the stirring shaft 232. The other connecting member 44 is disposed between the channel formed by the second flow pipe 43 and the other end of the heat absorption space 23201 to prevent the second flow pipe 43 from being damaged following the rotation of the stirring shaft 232.

[0048] Specifically, the connecting member 44 is implemented to include a rotary joint.

[0049] Those skilled in the art can understand that when the control member 12 controls the cooling suction member 412 and causes a suction force to be generated at the suction port of the cooling suction member 412, a negative pressure will be generated in the flow space 41101 through the channel formed by the connecting pipe 413. Then, the coolant in the heat absorption space 23201 will be sucked into the flow space 41101 through the channel formed by the second flow pipe 43. Under the heat conduction of the heat transfer layer, the temperature of the coolant in the flow space 41101 is reduced by the cooling liquid in the cooling space 41102. The cooled coolant will sequentially pass through the channel formed by the connecting pipe 413, the cooling suction member 412, and the first flow pipe 42 to flow back into the heat absorption space 23201, finally achieving the purpose of cooling the coolant in the heat absorption space 23201.

[0050] It is worth mentioning that the cooling liquid is introduced into the cooling space 41102 through the inlet 41103. Under the heat conduction of the heat transfer layer, after the heat of the coolant in the flow space 41101 is transferred to the cooling liquid in the cooling space 41102, the cooling liquid that has absorbed heat is discharged from the cooling space 41102 through the outlet 41104. By repeating this process, the purpose of reducing the temperature of the coolant in the flow space 41101 is achieved.

[0051] It should be noted that when the discharging suction member 322 causes a negative pressure to be generated in the grinding space 2102 through the suction pipe 321, and the ink to be ground in the storage member 91 enters the grinding space 2102 through the channel formed by the feeding pipe 311, when the ink to be ground entering the grinding space 2102 is greater than the storage capacity of the grinding space 2102, the ink to be ground in the grinding space 2102 will be sucked out from the grinding space 2102 through the suction pipe 321.

[0052] In this embodiment, the feeding member 31 further includes a feeding flow rate detection member 312. The feeding flow rate detection member 312 is installed on the feeding pipe 311. The feeding flow rate detection member 312 is used to detect the flow rate of the ink to be ground passing through the channel formed by the feeding pipe 311, so as to prevent the ink to be ground entering the grinding space 2102 from being sucked out of the grinding space 2102 by the suction pipe 321 because it is greater than the storage capacity of the grinding space 2102.

[0053] The discharging member 32 further includes a discharging flow rate monitoring member 323. The discharging flow rate monitoring member 323 is disposed in the suction pipeline 321, and is used for detecting the flow rate of the ground ink flowing through the suction pipeline 321, so as to facilitate controlling the flow rate of the ground ink extracted from the grinding space 2102, so as to avoid that the amount of the ground ink extracted is too much to be stored in a predetermined storage barrel.

[0054] Preferably, both the feeding flow rate detecting member 312 and the discharging flow rate monitoring member 323 are implemented as liquid flow meters.

[0055] Those skilled in the art can understand that when the grinding beads 22 impact the heat transfer protection layer, impact the stirring shaft 232, and impact the agglomerates in the ink to be ground, debris will be generated due to wear, and thus the quality of the ground ink will be affected because the ground ink contains the debris of the grinding beads 22.

[0056] The discharging member 32 further includes a discharging filter member 324. The discharging filter member 324 is disposed in the suction pipeline 321, and is used for filtering the debris of the grinding beads 22 contained in the ground ink.

[0057] Preferably, the discharging filter member 324 is implemented to include a backwash filter.

[0058] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments, and the embodiments of the present invention can have any deformation or modification without departing from the principle.
