Description

Technical Field

[0001] The invention relates to the technical field of pigment grinding, and in particular to an art pigment grinding device. Background Art

[0002] Pigment is a substance that can dye an object with color. It is an indispensable raw material for manufacturing paints, inks, oil painting pastes, cosmetic oil paints, colored paper, etc. In order to obtain good coloring effect and brightness, the pigment particles need to have fine particle size and uniform particle size distribution; before using art pigments, they need to be refined and homogenized to ensure that the pigments can be evenly dispersed. This step is crucial to improving the coloring power and brightness of the pigments; in the prior art, after grinding the material, the cleaning effect of the inside of the grinding device is poor.

[0003] For example, a grinder provided by authorization announcement number CN109701709B needs to be cleaned. The cleaning liquid only needs to be poured into the upper feed hopper and flows through the lower feed hopper to the conical guide platform, and flows along the conical guide platform to the inner wall of the cylinder, and flows downward along the inner wall of the cylinder. The power supply is connected, and the power supply makes the electromagnets on the two arc plates magnetic, and the magnetic poles of the opposite surfaces of the two electromagnets are the same, so that the two arc plates repel each other, so that the hard bristles on the two arc plates pass through the through holes on the side walls of the grinding roller and contact the inner wall of the cylinder. Under the cooperation of the first motor, the first gear, the gear ring and the second gear, the hard bristles on the grinding roller are combined with the cleaning liquid to clean the inner wall of the cylinder, and the residual food powder attached to the inner wall of the cylinder is scraped off.

[0004] It has major disadvantages: there are only two arc plates, and when the hard brush is extended, it cannot completely cover the surface of the grinding roller, thereby reducing the cleaning effect of the grinding device; at the same time, since both the grinding roller and the arc plate are arc-shaped, the arc plate cannot completely fit with the inner wall of the grinding roller after moving, resulting in some hard brushes cannot be fully extended, further reducing the cleaning effect; part of the material to be ground will fall on the upper side of the grinding roller and cannot fall off.

The abutment members are evenly distributed in the rolling cylinder 310 in a ring shape.

The gap between the outer ring of the rolling cylinder 310 and the outer ring of the grinding cylinder 110 is consistent with the minimum diameter of the ground pigment powder; The support assembly 100 further includes a feed port 111, a feed cylinder 120, a metal screen 130, a coarse grinding cylinder 140, a motor 150, a feed hole 161 and a collection box 170; The grinding cylinder 110 has a feed port 111 on the top side, the feed port 111 is in the shape of an inverted truncated cone, the axis of the feed port 111 is in the same straight line as the axis of the grinding cylinder 110, the feed cylinder 120 is in the shape of an inverted truncated cone that passes through along its axis, the axis of the feed cylinder 120 is in the same straight line as the axis of the grinding cylinder 110, the feed cylinder 120 is fixed in the feed port 111, there are two rough grinding cylinders 140, and the rough grinding cylinders 140 are symmetrically connected to the grinding cylinder 110 for rotation; There are two motors 150, which correspond to the two rough grinding cylinders 140 one by one. The motor 150 is fixed to one side of the grinding cylinder 110, and the output end of the motor 150 is fixed to the rotating rod of the rough grinding cylinder 140; A gap is left between the two rough grinding cylinders 140; The unloading plate 160 is provided with unloading holes 161, and there are a plurality of unloading holes 161, which are evenly spaced and located at the outer circle of the fixing frame 220. The metal screen 130 is fixed on the top side of the unloading hole 161, and the mesh of the metal screen 130 is consistent with the minimum diameter of the ground pigment powder; The collection box 170 is detachably disposed at the bottom side of the grinding cylinder 110; The power assembly 200 also includes a motor three 210 and a shunt block 260; There are two motors 3 210, which correspond to the two rolling cylinders 310 one by one. The motors 3 210 are fixed in the support plate 250. The output end of the motors 3 210 is fixed on the rotating rod rotatably connected to the guide block 320. The rotation axis of the motors 3 210 and the rotating rod rotatably connected to the guide block 320 are on the same straight line. The diverter block 260 is in a cone shape, the axis of the diverter block 260 is in the same straight line as the axis of the grinding cylinder 110, and the diverter block 260 is fixed to the upper side of the support plate 250; The maximum diameter of the diverter block 260 is consistent with the outer diameter of the support plate 250; The support plate 250 has a heat dissipation hole 251 on the bottom side, and a dustproof net is fixed inside the heat dissipation hole 251; The electric slide 330 is a prior art and will not be described in detail here.

[0023] During use, the pigment to be ground is put in through the feed barrel 120. Before putting in, the motor 150 is energized, and the motor 150 drives the coarse grinding barrel 140 to rotate. The two coarse grinding barrels 140 rotate in opposite directions, and the rotation direction of the side close to each other is consistent with the falling direction of the pigment. The pigment after coarse grinding falls on the diverter block 260 and falls on the guide block 320 and the unloading plate 160 through the inclined side. Then the motor 230 is started, and the support block 250 is driven to rotate by the motor 230. During the rotation, the pigment on the diverter block 260 is thrown off. At the same time, the motor 3 210 drives the rolling barrel 310 to rotate. The rotation direction of the rolling barrel 310 is opposite to that of the support block 250. During the rotation, the pigment on the guide block 320 is thrown off, and the powder in front of the rotation is pushed to the side close to the support block 250. The pigment is ground on one side of the inner wall of the grinding cylinder 110. During the grinding process, qualified pigment powder can fall into the collection box 170 through the mesh of the metal screen 130. During the grinding process, the electric slide 330 can be controlled to drive the push rod 360 to move, so that the push rod 360 extends into the opening 311 to impact the pigment in the pressed part. After the grinding is completed, cleaning liquid and water are continuously poured into the interior to clean the interior. The motor 230, the motor 310 and the electric slide 330 are still operating. The push rod 360 is extended and retracted to clean the pigment attached to the inner wall of the grinding cylinder 110, scrape it off, and disperse it by impact. At the same time, the height of the rolling cylinder 310 can be adjusted by the telescopic rod 240 to completely clean the inner wall of the grinding cylinder 110. The cleaned waste is discharged through the metal screen 130.

[0024] Compared with the prior art, a single movable plate 350 can be controlled individually, so that multiple push rods 360 can be fully extended and evenly distributed on the surface of the grinding cylinder 310, which can improve the grinding efficiency of the pigment and improve the cleaning effect of the inner wall of the grinding cylinder 110; at the same time, the addition of the guide block 320 can prevent the ground pigment from falling on the upper side of the grinding cylinder 310.

[0025] Embodiment 2: When the embodiment 1 is in use, since the surface of the rolling cylinder 310 has a plurality of openings 311, during the use of the rolling cylinder 310, the rolled pigment will enter the rolling cylinder 310 through the openings 311, resulting in waste of pigment and blockage of the openings 311. At the same time, the cleaning effect on the surface of the rolling cylinder 310 is poor. Based on this, the solution of the embodiment 1 is improved, such as Figure 7 As shown: The rolling assembly 300 further includes a resisting film 370, the number of which is consistent with the sum of the number of the through openings 311 in the plurality of telescopic groups, and the plurality of resisting films 370 corresponds to the plurality of through openings 311 one by one; The resistance film 370 is fixed in the opening 311 , and the resistance film 370 blocks the opening 311 . The resistance film 370 is made of rubber.

[0026] When in use, while the rolling cylinder 310 is grinding the pigment, the resistance film 370 can block the opening 311. At the same time, when the grinding cylinder 110 is cleaned, the push rod 360 is inserted into the opening 311 to deform the resistance film 370. At this time, the electric slide 330 is powered off, and the resistance film 370 rebounds through elastic force. The resistance film 370 resists the push rod 360 to reset and slides on the electric slide 330. In the process of resetting the resistance film 370, the entire rolling cylinder 310 can vibrate to shake off the powder particles on the surface.

[0027] A layer of resistance film 370 is fixed in the opening 311, and the resistance film 370 can prevent the pigment from entering the interior of the rolling cylinder 310, thereby improving the blocking effect; at the same time, when the top rod 360 resists the resistance film 370, it can cause it to deform, and in the process of its elastic reset, it can make the rolling cylinder 310 vibrate, and the powder particles on the surface of the resistance film 370 can be shaken off, thereby improving the cleaning effect on the surface of the rolling cylinder 310.

[0028] Embodiment 3: When the above device is in use, the resetting of the resistance film 370 generates vibration, so that the rolling cylinder 310 generates vibration, but the cleaning effect on the inner wall of the grinding cylinder 110 is poor; at the same time, the grinding cylinder 110 needs to be rotated several times to complete the grinding, and the rotation grinding effect is poor. Based on this, the solution of embodiment 2 is improved, such as Figure 8-Figure 10 As shown: It also includes adjustment components 400, the number of which is consistent with the number of the abutment members and corresponds one to one; The adjustment assembly 400 includes an electric slide 410, a slider 420 and a sliding plate 430; The second electric slide 410 is fixed to a side of the moving plate 350 close to the through opening 311, the second slider 420 is slidably arranged on the second electric slide 410, the sliding plate 430 is fixed to a side of the second slider 420 away from the second electric slide 410, the push rod 360 is rotatably arranged on the sliding plate 430, and the rotation direction of the push rod 360 is perpendicular to the ground; A torsion spring is sleeved on the rotating rod that rotatably connects the top rod 360 and the sliding plate 430, and the two ends of the torsion spring are respectively fixed on the top rod 360 and the sliding plate 430; The push rod 360 and the sliding plate 430 are rotatably connected to the torsion spring on the rotating rod, and the push rod 360 faces the through hole 311 when no external force is applied; The cross section of the through opening 311 parallel to the ground is fan-shaped; One end of the push rod 360 away from the second slider 420 is fixed to the middle of the abutment membrane 370; The electric slide 2 410 is a prior art and will not be described in detail here.

[0029] During the rotation of the rolling cylinder 310, the electric slide 410 can be controlled to drive the slider 420 to move, so that the angle of the push rod 360 changes. When the angle changes, the resistance film 370 is deformed, and an extrusion space is formed on one side. Some ground pigment powder is expanded into the extrusion space. When the angle of the push rod 360 is constantly changing, the powder in the extrusion space is pressed. At the same time, when the grinding cylinder 110 is cleaned after grinding, the push rod 360 with a changed angle can scrape the inner wall of the grinding cylinder 110 back and forth, and the deformation of the resistance film 370 can generate greater vibration. At the same time, the swinging push rod 360 can grind the ground pigment powder. The pigment accumulated between the inner wall of the grinding cylinder 110 and the rolling cylinder 310 is broken up; when the inner wall of the grinding cylinder 110 is cleaned, the electric slide 1 330 and the electric slide 2 410 are made to work intermittently, and the electric slide 2 410 drives the slider 2 420 to move, so that the angle of the push rod 360 changes, and the push rod 360 with the changed angle can scrape the inner wall of the grinding cylinder 110 back and forth, and when the electric slide 1 330 drives the push rod 360 to move to the side away from the resistance film 370, the resistance film 370 is pulled to deform, and after the electric slide 1 330 is powered off, the resistance film 370 is reset by elastic force, so that the resistance film 370 vibrates and can hit the inner wall of the grinding cylinder 110 to generate vibration.

[0030] By changing the angle of the push rod 360, an extrusion space is formed, which can improve the grinding effect of the pigment particles; at the same time, the push rod 360 with a constantly changing angle contacts the inner wall of the grinding cylinder 110, scrapes the inner wall of the grinding cylinder 110 back and forth, and drives the push rod 360 with the electric slide 330 to move to the side away from the resistance film 370, pulling the resistance film 370 to deform, and after the electric slide 330 is powered off, the resistance film 370 is reset by elastic force, causing the resistance film 370 to vibrate, which can further improve the cleaning effect on the inner wall of the grinding cylinder 110; after the deformation, the resistance film 370 has greater elastic potential energy, and can generate greater vibration during the resetting process. At the same time, when the angle of the push rod 360 changes, it can hit the inner wall of the opening 311 to generate vibration, thereby improving the cleaning effect on the outer wall of the rolling cylinder 310; at the same time, the swinging push rod 360 can break up the pigment accumulated between the inner wall of the grinding cylinder 110 and the rolling cylinder 310, thereby improving the pigment grinding effect.

[0031] Embodiment 4: When the embodiment 3 is in use, there will be a lot of pigment accumulation between the inner wall of the grinding cylinder 110 and the rolling cylinder 310 due to the continuous pressing of the rolling cylinder 310. The effect of breaking up the pigment by the swing of the top rod 360 alone is poor. Based on this, the solution of the embodiment 3 is improved, such as Figure 11-Figure 12 As shown: The interior of the resistance film 370 is hollow; The rolling assembly 300 further includes an air pump 380 , which is fixed to the inner bottom side of the rolling cylinder 310 , and the output end of the air pump 380 is connected to the inner cavity of the abutment membrane 370 .

[0032] During the process of grinding the pigment, the intermittent operation of the air pump 380 can intermittently expand the resistance film 370, and the expanded resistance film 370 can improve the cleaning of the pigment blocks accumulated between the inner wall of the grinding cylinder 110 and the rolling cylinder 310; at the same time, during the cleaning process of the grinding cylinder 110, the intermittent expansion of the resistance film 370 increases the contact area between the resistance film 370 and the inner wall of the grinding cylinder 110, which can improve the cleaning effect of the inner wall of the grinding cylinder 110.

[0033] The resistance film 370 is an airbag structure. During the process of grinding the pigment, the resistance film 370 expands and can resist the agglomerated pigments, causing them to disperse and detach from the inner wall of the grinding cylinder 110, thereby improving the grinding efficiency of the pigment. At the same time, when cleaning the inner wall of the grinding cylinder 110, the resistance film 370 expands and can increase the contact area with the inner wall of the grinding cylinder 110, thereby expanding the area and further improving the cleaning effect.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
