[0032] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0033] Embodiment 1 ​

[0034] Reference Figures 1-4 For the first embodiment of the present application, the embodiment provides a cooling device for a grinding machine for preparing inkjet ink color paste.

[0035] Specifically, the main assembly 100 includes a device body 101, a driving motor 102 arranged at the end of the device body 101, and a grinding cavity 103 arranged on the outer wall of the device body 101.

[0036] The cooling assembly 200 arranged at the end of the device body 101 includes a fan 201, a blowing pipe 202 in communication with the fan 201, and an air inlet pipe 203, the end of the air inlet pipe 203 is in communication with the grinding cavity 103 and the inner wall is provided with an anti-overflow component, the anti-overflow component is used to send air to the inside of the grinding cavity 103 while preventing the internal water paste from overflowing, and the inner wall of the grinding cavity 103 is also provided with a dissipation component for dissipating heat inside the grinding cavity 103 to the outside.

[0037] Among them, the top of the device body 101 is provided with an adjusting table 1011 for regulating the driving motor 102, and the driving motor 102 drives the grinding roller 1012 to rotate in the grinding cavity 103 through a gear box, when making the color paste, the grinding medium and the material are added to the inside of the grinding cavity 103, and the grinding roller 1012 is driven to stir the grinding medium and the material and finally generate the color paste.

[0038] When the temperature inside the grinding cavity 103 is too high, it will affect the generated color paste, so it is necessary to cool the inside of the grinding cavity, through the cooperation of the cooling assembly 200 and the cooling channel 1031, on the basis of water cooling, a cooling process is added to quickly cool the inside, the fan 201 blows air into the blowing pipe 202, then through the air inlet pipe 203 into the inside of the grinding cavity 103, directly cools the inside material, and the anti-overflow component in the air inlet pipe 203 can effectively prevent the inside material from entering the inside of the air inlet pipe 203 during grinding, and the dissipation component in the grinding cavity 103 will exhaust the heat inside to the outside and prevent the material inside from being exhausted.

[0039] Embodiment 2

[0040] Reference Figures 3-5 For the second embodiment of the present application, the embodiment is based on the previous embodiment.

[0041] Specifically, the anti-overflow component includes a blocking block 204 fixed to the inner wall of the air inlet pipe 203, and the end of the grinding cavity 103 is arrayed with an air inlet 1032, the end of the air inlet pipe 203 extends to the inner wall of the air inlet 1032 and is in communication with the grinding cavity 103, and the blocking block 204 is used to block the color paste inside the grinding cavity 103.

[0042] The blocking block 204 is fixed on the inner wall of the air inlet pipe 203 and located in the air inlet 1032 at the upper end of the grinding cavity 103. The air blown by the fan 201 passes through the blocking block 204 and enters the inner chamber of the lower grinding cavity 103 to cool the material. A filter layer is arranged in the air inlet pipe 203 to filter the air and prevent impurities from the outside from mixing into the material, affecting the formation and stability of the final color paste.

[0043] Preferably, the blocking block 204 is provided with a notch 2041 at the end and a flow channel 2042 is arranged through the inner wall of the blocking block 204. The flow channel 2042 is used for the cold air to pass through, and the outer wall of the flow channel 2042 is provided with a reverse channel 2043 for blocking the internal color paste from flowing backward.

[0044] The top end of the blocking block 204 is provided with a notch 2041, which is aligned with the direction of the air inlet. A flow channel 2042 is arranged through the inside of the blocking block 204 for the air to pass through. Through the notch 2041 and the flow channel 2042, the flow rate of the air inside the air inlet pipe 203 is accelerated when it passes through the flow channel 2042, so that the air force blows downward into the inside of the grinding cavity 103 at a faster speed.

[0045] A reverse channel 2043 is also arranged on the side of the flow channel 2042. The reverse channel 2043 does not affect the normal passage of the air force, but when the internal material is affected by the centrifugal force generated by the rotation of the grinding roller 1012 and is thrown upward, even if it accidentally enters the inside of the flow channel 2042, due to the structural problem, the material will enter the reverse channel 2043 and flow along the reverse channel 2043 when it flows upward along the flow channel 2042, and will impact the material inside the flow channel 2042, to offset the upward driving force of the material inside the flow channel 2042. Cooperate with the blowing of the air force to blow down all the material, prevent the internal color paste from flowing backward.

[0046] The end of the air inlet pipe 203 is also provided with an air outlet valve 205, and the end face of the air outlet valve 205 is provided with an opening 2051. The end of the air outlet valve 205 is also provided with a fixed ring 206, and the inner wall of the fixed ring 206 is arrayed with a bimetallic valve plate 2061. The bimetallic valve plate 2061 is attached to the outer wall of the air outlet valve 205 and covers the opening 2051. When the temperature inside the grinding cavity 103 rises, the bimetallic valve plate 2061 moves away from the opening 2051.

[0047] The air outlet valve port 205 is located below the blocking block 204, and the surface array is provided with a plurality of openings 2051. The air in the air inlet pipe 203 is accelerated through the flow channel 2042 and then blown downward through the openings 2051 into the interior of the grinding cavity 103. Due to the presence of the openings 2051, the air force is diffused in all directions, increasing the contact area of the air force and the material and improving the heat dissipation effect.

[0048] The lower surface of the air outlet valve port 205 is also provided with a plurality of bimetallic valve plates 2061. In the initial state, the bimetallic valve plates 2061 are tightly attached to the air outlet valve port 205 and cover part of the openings 2051. When the temperature inside the grinding cavity 103 rises, the bimetallic valve plates 2061 are bent due to thermal expansion, moving away from the openings 2051, so that all the openings 2051 of the air outlet valve port 205 are opened, and the heat dissipation efficiency for the material reaches the maximum.

[0049] Preferably, the inner wall of the grinding cavity 103 is provided with a cooling channel 1031 for water flow to pass through for cooling, and the end of the grinding cavity 103 is also provided with an air outlet 1033. The inner wall of the grinding cavity 103 is also provided with an air exhaust pipe 1034, the starting end of which is close to the air inlet 1032 and the terminal end is close to the air outlet 1033.

[0050] The cooling channel 1031 in the inner wall of the grinding cavity 103 has a cold circulating water flow that flows all the time to cool the material in the grinding cavity 103. A plurality of air exhaust pipes 1034 are also provided in the interior of the grinding cavity 103. The starting end and the terminal end of the air exhaust pipe 1034 are above the inner wall of the grinding cavity 103, avoiding the entry of the ground color paste material into the interior. The starting end is close to the position of the air outlet 1033, which is more conducive to the entry of the air force, and the air force carrying heat is transported to the air outlet 1033 through the air exhaust pipe 1034, which is conducive to the discharge of heat from the interior of the grinding cavity 103.

[0051] In summary, when in use, during normal grinding, the temperature inside the grinding cavity 103 is not high, and the temperature of the interior color paste is regulated through the cooling channel 1031. At the same time, the fan 201 is started, and the two are coordinated. The cold air enters the air inlet pipe 203 through the blowing pipe 202, is accelerated through the flow channel 2042 of the blocking block 204 due to the guiding effect of the notches 2041, and is blown into the interior of the grinding cavity 103 through the openings 2051 of the air outlet valve port 205. At this time, part of the openings 2051 are blocked by the bimetallic valve plates 2061 and cannot realize air supply. The airflow passing through is diffused in all directions, contacts the material, and cools it.

[0052] When the grinding roller 1012 rotates at a low speed during grinding, the color paste is less affected by the centrifugal force, and a small amount of color paste splashed into the flow channel 2042 is blocked by the reverse channel 2043 and cannot enter the air inlet pipe 203. At the same time, the filter layer in the air inlet pipe 203 intercepts external impurities to avoid contaminating the material.

[0053] The cooling channel 1031 circulates cold water to absorb heat, and the air outlet 1033 is used to push a small amount of hot air out of the air outlet 1033 by using the air inlet flow. The escape component blocks the color paste from overflowing with the air flow.

[0054] When the temperature of the grinding cavity 103 increases, the bimetallic valve plate 2061 bends due to thermal expansion, and the air outlet 2051 is far away from the air outlet 2051, so that the opening of the air outlet valve 205 is fully opened, and the cold air flow increases significantly, rapidly reducing the temperature of the material.

[0055] The high-speed rotation of the grinding roller 1012 causes the color paste to splash violently, and a large amount of color paste impacts the blocking block 204. At this time, the blocking effect of the reverse channel 2043 is enhanced, and the air flow is accelerated by the fully opened opening 2051 to form a strong air pressure downward, which suppresses the splashing trend of the color paste and prevents backflow.

[0056] And the air outlet pipe 1034 increases the air inlet flow and the internal air flow speed, and the air outlet 1033 is used to quickly discharge hot air, and the baffle 304 of the escape component is turned over under the action of the air flow to form a larger heat dissipation channel, and the baffle 3041 is used to link the whole structure to keep the whole structure stable, and ensure that the hot air is discharged efficiently and the color paste does not overflow.

[0057] Embodiment 3

[0058] Reference Figure 4 、 Figures 6-8 This is the third embodiment of the present application, which is based on the previous embodiment.

[0059] Specifically, the inner wall of the air outlet 1033 is provided with an air outlet pipe 301, and the escape component is installed in the inner wall of the air outlet pipe 301. The escape component includes a settling tank 302, and the end of the settling tank 302 is provided with a connecting rod 3021. The end of the settling tank 302 is also provided with a mounting ring 303, and the inner wall of the mounting ring 303 is arrayed with baffles 304, which are used to block the color paste inside.

[0060] The settling tank 302 is installed in the inner wall of the air outlet pipe 301, and the tank is filled with multiple layers of metal wire mesh and the mesh layers are filled with spherical copper beads. The exhaust air flow is suddenly reduced in flow rate due to the expansion of the cross-sectional area, and the particles are captured by the copper beads due to gravity and inertia, and the clean air is discharged from the top of the tank.

[0061] The surface of the baffle 304 is configured with a counterweight so that the weight of both sides of the baffle 304 is different. Due to the influence of the airflow inside the grinding cavity 103, the baffle 304 will overturn when the airflow fluctuates, so that the heat inside is carried outward by the wind.

[0062] Preferably, the inner wall of the baffle 304 is provided with a through hole 3042, and the inner wall of the through hole 3042 is provided with a support 305. The outer wall of the baffle 304 is provided with a partition buckle 3041, and adjacent baffles 304 are integrated through the partition buckle 3041.

[0063] Among them, the baffle 304 is arranged in an array, and a sealing surface is formed by the partition buckles 3041 on the side edges of adjacent baffles 304 to completely block the lower part of the air outlet pipe 301. Only when the baffle 304 overturns, a gap will be opened to discharge heat.

[0064] The outer part of the support 305 is provided with a sliding column 3051, and the end of the sliding column 3051 extends into the movement groove 3043 formed in the inner wall of the through hole 3042 and slides with it. One end of the support 305 is located in the inner wall of the end of the connecting rod 3021, and the other end extends into the inner wall of the mounting ring 303.

[0065] Among them, the support 305 is installed in the middle of the baffle 304 and moves inside the baffle 304. The baffle 304 is installed and fixed inside the mounting ring 303 and the connecting rod 3021 through the support 305. The two ends of the support 305 respectively extend into the mounting ring 303 and the connecting rod 3021. When the baffle 304 is overturned by the airflow, the support 305 moves linearly inside the baffle 304 through the movement groove 3043.

[0066] One end of the support 305 extends into the accommodating groove 3031 formed in the inner wall of the mounting ring 303. When the baffle 304 overturns, the end of the support 305 moves in the inner wall of the accommodating groove 3031. The outer wall of the end of the support 305 is also provided with a limiting block 3052, and the outer wall of the limiting block 3052 extends into the slide 3032 formed in the inner wall of the accommodating groove 3031 and slides with it.

[0067] Among them, the limiting block 3052 at the end of the support 305 slides in the slide 3032 inside the accommodating groove 3031, so that the support 305 only moves linearly when it slides in the accommodating groove 3031 and does not rotate.

[0068] Preferably, the inner wall of the accommodating groove 3031 is also provided with a first elastic member 306, and the first elastic member 306 is used to push the support 305 back to its original position.

[0069] The first elastic member 306 is installed inside the accommodating groove 3031 and abuts against the outer wall of the support 305, and in the initial state, pushes the support 305 to make the other end of the support 305 close to the connecting rod 3021. When the baffle 304 is flipped, the support 305 is displaced and presses the first elastic member 306 under the influence of the movement groove 3043. At this time, the first elastic member 306 is compressed under force and the outer baffle 304 is flipped to have a gap between each other for the gas to flow through. Then, the first elastic member 306 restores the deformation to reset the support 305 and push the baffle 304 to rotate back to be closely attached again.

[0070] In summary, in use, when the interior of the grinding cavity 103 is in a normal air flow state, and there is no wind or slight wind inside, the initial state of the baffle 304 is affected by the first elastic member 306, the first elastic member 306 pushes the support 305 to move to the connecting rod 3021 direction, so that the baffle 304 is closely attached, a sealing surface is formed by the separation baffle 3041, and the air outlet pipe 301 is completely blocked, and the multi-layer metal wire mesh and the spherical copper beads in the settling tank 302 are in a static state and no air flow passes through.

[0071] When the interior air flow of the grinding cavity 103 is in a fluctuating state, the air flow in the grinding cavity 103 fluctuates, and the hot air discharged by the air exhaust pipe 1034 impacts the baffle 304. Due to the uneven weight of the baffle 304 on both sides, the baffle 304 is flipped and the gap is opened. The support 305 linearly slides inside the through hole 3042, and the limiting block 3052 moves in the sliding way 3032 to ensure that the baffle 304 is stably flipped. At this time, the first elastic member 306 is compressed to store elastic potential energy.

[0072] The hot air carrying a small amount of colorant particles enters the settling tank 302 through the gap, and the air flow is decelerated due to the enlarged cross-sectional area in the tank. The particles are captured by the copper beads and the metal wire mesh due to gravity and inertia, and the purified air is discharged from the top of the settling tank to achieve heat dissipation and dust removal.

[0073] After the air flow disappears, the first elastic member 306 releases the potential energy to push the support 305 to reset, drive the baffle 304 to rotate back, and the separation baffle 3041 is re-docked to restore the sealing state.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
