Description

Technical Field

[0001] This utility model relates to the field of art painting pigment processing, specifically an art painting pigment sanding device. Background Technology

[0002] Horizontal sand mill is a high-efficiency wet ultrafine grinding equipment and belongs to the core category of sand mills. Horizontal sand mill achieves material refinement through "collision, friction and shearing force generated by the high-speed movement of grinding media". It is widely used in coatings, inks, pigments, cosmetics, food and other fields. It is especially suitable for grinding solid-liquid mixtures (slurries) to micron or even nanometer fineness. Its core advantages are high grinding efficiency, uniform material dispersion and strong continuous operation capability.

[0003] Existing art painting pigment grinding devices add abrasive to the inside of the cylinder during the grinding process, causing the grinding media and pigment slurry to move violently. The media breaks down and refines the pigment particles through collision, friction, and shearing. However, the abrasive needs to be replaced after prolonged use. Currently, when replacing the grinding media in traditional horizontal sand mills (such as glass beads, zirconium aluminum composite beads, etc.), a series of steps must be manually performed each time: "disassembling the cylinder sealing structure → manually emptying the old media → cleaning the residual media inside the cylinder → reassembling the cylinder → adding new media". This replacement process is cumbersome and time-consuming, thus reducing the efficiency of abrasive disc discharge and replacement. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a sanding device for art painting pigments, so as to solve the technical problem of the inconvenience of discharging and replacing the abrasive inside the cylinder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sanding device for art painting pigments, comprising a first support frame, a second support frame, and a third support frame. A base plate is placed on the top of the first and second support frames. A housing is installed on the top of the base plate, and a cylinder is installed on one side of the housing. A movable shaft is rotatably connected between the cylinder and the third support frame via a bearing. A positioning groove is provided on the top of the third support frame, and a positioning protrusion is installed on one side of the bottom of the base plate. Two hydraulic cylinders are installed inside the first support frame, and a lifting plate is installed at the output end of the hydraulic cylinders via a piston rod. A push plate is rotatably connected between the lifting plate and the base plate via a pin.

[0006] By adopting the above technical solution, when the hydraulic cylinder is working, the piston rod can be extended, which in turn drives the lifting plate to move up. The lifting plate then pushes the push plate to rotate, which in turn pushes the bottom plate to rotate, thereby causing the cylinder to rotate and tilt.

[0007] Furthermore, cushioning pads are installed on the top of both the first and second support frames, with the top of the cushioning pads fitting against the bottom of the base plate, and the cushioning pads are made of polyurethane material.

[0008] By adopting the above technical solution, the buffer pad reduces the vibration and noise generated during the grinding process, while avoiding wear caused by hard contact between the base plate and the support frame.

[0009] Furthermore, a guide rod is installed inside the first support frame, and the guide rod passes through the lifting plate.

[0010] By adopting the above technical solution, the guide rod can guide the lifting plate, thereby improving the stability of the lifting plate when it moves, and preventing the lifting plate from deviating or jamming when driven by the hydraulic cylinder, thus ensuring the stability and accuracy of the tilting drive.

[0011] Furthermore, the first support frame and the second support frame are connected by a connecting frame, and the bottom of the first support frame, the second support frame and the third support frame are all provided with anti-slip pads made of silicone rubber material.

[0012] By adopting the above technical solution, the anti-slip mat increases the friction between the support frame and the ground, preventing equipment from shifting and improving overall stability.

[0013] Furthermore, the interior of the housing is rotatably connected to a rotating shaft via a sealed bearing, and one end of the rotating shaft extends into the interior of the cylinder, with a driven gear mounted on the outer wall of the rotating shaft.

[0014] By adopting the above technical solution, when the driven gear rotates, it will drive the shaft to rotate, and the setting of the sealed bearing enables the shaft to rotate stably.

[0015] Furthermore, the outer wall of the rotating shaft is also equipped with multiple grinding discs, and the grinding discs are located inside the cylinder.

[0016] By adopting the above technical solution, the grinding disc rotates at high speed with the shaft, and the grinding media moves violently through the stirring of the grinding disc, which enhances the collision and shearing effect and improves the grinding efficiency.

[0017] Furthermore, a drive motor is also installed on the top of the base plate, and the output end of the drive motor is connected to a drive gear through a drive shaft. The drive gear is located inside the housing and meshes with the driven gear.

[0018] By adopting the above technical solution, the drive motor can drive the active gear to rotate, and the active gear in turn drives the driven gear to rotate.

[0019] Furthermore, a diaphragm pump is installed on one side of the top of the housing, and the inlet end of the diaphragm pump is connected to a pumping hose, and the outlet end of the diaphragm pump is connected to a conveying pipe extending into the interior of the housing.

[0020] By adopting the above technical solution, the diaphragm pump extracts pigment through the extraction hose and sends it into the cylinder through the delivery pipe, thereby realizing "automatic feeding" and avoiding the unevenness of manual feeding. In addition, the diaphragm pump is suitable for high-viscosity pigment slurry and prevents clogging.

[0021] Furthermore, an abrasive injection pipe is connected to one side of the top of the cylinder, and a sealing cap is threaded to the top of the abrasive injection pipe. A separation rotor is installed at one end of the rotating shaft, and the separation rotor is located inside the cylinder. The outer wall of the separation rotor has multiple openings.

[0022] By adopting the above technical solution, the abrasive injection pipe is designed to facilitate the addition of grinding media, the separation rotor can generate centrifugal force by rotating with the shaft to separate the media from the slurry, and the opening is designed to facilitate the entry of the ground material into the separation rotor.

[0023] Furthermore, a cover plate is installed on one side of the cylinder by multiple bolts, and a screen cylinder is installed on one side of the cover plate. The screen cylinder is located inside the separating rotor, and a discharge pipe is connected to the other side of the cover plate, and the discharge pipe is connected to the screen cylinder.

[0024] By adopting the above technical solution, the screen cylinder can filter fine media particles and prevent them from being discharged with the slurry; while the discharge pipe can discharge qualified slurry.

[0025] In summary, the present invention has the following main advantages: 1. This utility model uses a hydraulic cylinder to drive and the cylinder body can be rotated and tilted through a movable shaft to realize the automatic tilting and material discharge of the cylinder body. The grinding media inside the cylinder body is automatically discharged to the collection device under the action of gravity. This process does not require manual disassembly of the cylinder body or manual tilting, reducing the intensity of manual operation and shortening the media replacement time. It is suitable for the frequent material replacement needs of multi-variety production of art pigments and improves the discharge efficiency of abrasive. 2. This utility model reduces vibration and noise generated during grinding by setting a buffer pad made of polyurethane material, while avoiding wear caused by hard contact between the base plate and the support frame; by setting a guide rod, the guide rod can guide the lifting plate, thereby improving the stability of the lifting plate when moving, and preventing the lifting plate from deviating or jamming when driven by the hydraulic cylinder, ensuring the stability and accuracy of the tilting drive.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1:

[0031] A device for grinding art painting pigments, such as Figures 1-7As shown, the system includes a first support frame 1, a second support frame 4, and a third support frame 24. A base plate 2 is placed on top of the first support frame 1 and the second support frame 4. A housing 5 is installed on top of the base plate 2, and a cylinder 14 is installed on one side of the housing 5. A movable shaft 25 is rotatably connected to the cylinder 14 and the third support frame 24 via a bearing. A positioning groove 17 is provided on the top of the third support frame 24, and a positioning protrusion 16 is installed on one side of the bottom of the base plate 2. The positioning protrusion 16 is located inside the positioning groove 17. Two hydraulic cylinders 26 are installed inside the first support frame 1, and a lifting plate 27 is installed at the output end of the hydraulic cylinder 26 via a piston rod. A push plate 28 is rotatably connected to the lifting plate 27 and the base plate 2 via a pin. When the hydraulic cylinder 26 works, the piston rod can be extended, thereby driving the lifting plate 27 to move upward. The lifting plate 27 then pushes the push plate 28 to rotate, and the push plate 28 pushes the base plate 2 to rotate, thereby driving the cylinder 14 to rotate, causing the cylinder 14 to tilt.

[0032] See Figures 1-7 The first support frame 1 and the second support frame 4 are connected by a connecting frame. The bottoms of the first support frame 1, the second support frame 4, and the third support frame 24 are all equipped with anti-slip pads made of silicone rubber. These anti-slip pads increase the friction between the support frame and the ground, preventing equipment displacement and improving overall stability. A rotating shaft 6 is rotatably connected inside the housing 5 via a sealed bearing. One end of the rotating shaft 6 extends into the interior of the cylinder 14, and a driven gear 7 is installed on the outer wall of the rotating shaft 6. When the driven gear 7 rotates, it drives the rotating shaft 6 to rotate. The sealed bearing ensures stable rotation of the rotating shaft 6. Multiple grinding discs 18 are also installed on the outer wall of the shaft 6, and the grinding discs 18 are located inside the cylinder 14. The grinding discs 18 rotate at high speed with the shaft 6. The grinding discs 18 stir and drive the medium to move violently, which enhances the collision and shearing effect and improves the grinding efficiency. The top of the base plate 2 is also equipped with a drive motor 9, and the output end of the drive motor 9 is connected to the drive gear 8 through the drive shaft. The drive gear 8 is located inside the housing 5. The drive gear 8 meshes with the driven gear 7. When the drive motor 9 works, it can drive the drive gear 8 to rotate, and the drive gear 8 will drive the driven gear 7 to rotate.

[0033] See Figures 1-5A diaphragm pump 11 is installed on one side of the top of the housing 5. The inlet end of the diaphragm pump 11 is connected to a suction hose 13, and the outlet end of the diaphragm pump 11 is connected to a conveying pipe 12 extending into the housing 5. The diaphragm pump 11 draws pigment through the suction hose 13 and sends it into the cylinder 14 through the conveying pipe 12, thereby realizing "automatic feeding" and avoiding the unevenness of manual feeding. The diaphragm pump 11 is suitable for high-viscosity pigment slurries and prevents clogging. An abrasive injection pipe 15 is connected to one side of the top of the cylinder 14, and a sealing cap is threaded to the top of the abrasive injection pipe 15. A separating rotor 19 is installed at one end of the rotating shaft 6 and is located inside the cylinder 14. The outer wall of the separating rotor 19 has multiple openings 20. The abrasive injection pipe 15 facilitates the addition of grinding media. The abrasive can be glass beads (silica material), zircon-alumina composite beads (zircon sand + alumina composite material), or high-purity oxide. Zirconia beads (made of zirconium dioxide) are used in the separation rotor 19, which generates centrifugal force as it rotates with the shaft 6 to separate the medium from the slurry. The opening facilitates the entry of the ground material into the separation rotor 19. A cover plate 22 is installed on one side of the cylinder 14 by multiple bolts. A screen cylinder 21 is installed on one side of the cover plate 22. A sealing ring made of silicone rubber is also provided on one side of the cover plate 22. The sealing ring fits against the inner wall of the cylinder 14. The screen cylinder 21 is located inside the separation rotor 19. The other side of the cover plate 22 is connected to the discharge pipe 23, which is connected to the screen cylinder 21. The screen cylinder 21 can filter fine medium particles to prevent them from being discharged with the slurry. The discharge pipe 23 can discharge qualified slurry. A control box 3 is installed on the other side of the shell 5. The control box 3 is electrically connected to the hydraulic cylinder 26, the drive motor 9, and the diaphragm pump 11, respectively, so that the hydraulic cylinder 26, the drive motor 9, and the diaphragm pump 11 can be started or stopped through the control box 3.

[0034] Example 2:

[0035] Based on the above embodiment one, in order to reduce the vibration and noise generated by the equipment during grinding, the following structure will be set.

[0036] Specifically, buffer pads 10 are installed on the top of the first support frame 1 and the top of the second support frame 4. The top of the buffer pads 10 are in contact with the bottom of the base plate 2. The buffer pads 10 are made of polyurethane material. The buffer pads 10 reduce the vibration and noise generated by the equipment during grinding, and at the same time avoid wear caused by hard contact between the base plate 2 and the support frame.

[0037] Example 3:

[0038] Based on the above embodiment 1, in order to improve the stability of the lifting plate 27 when it moves, it needs to be guided, so the following structure will be set.

[0039] Specifically, a guide rod 29 is also installed inside the first support frame 1. The guide rod 29 passes through the lifting plate 27 and can guide the lifting plate 27, thereby improving the stability of the lifting plate 27 when it moves and preventing the lifting plate 27 from deviating or jamming when driven by the hydraulic cylinder 26, thus ensuring the stability and accuracy of the tilt drive.

[0040] The working principle of this utility model is as follows: First, before use, the operator can connect the power supply, then open the sealing cover on the abrasive injection pipe 15, add grinding media (such as zirconium aluminum composite beads) that are suitable for the fineness of the pigment, and close the sealing cover; start the diaphragm pump 11, and draw the pigment slurry to be ground (such as acrylic pigment slurry) through the suction hose 13, and send it into the cylinder 14 through the conveying pipe 12. Then start the drive motor 9, and the drive motor 9 drives the active gear 8 to rotate through the drive shaft. The active gear meshes with the driven gear 7, which in turn drives the rotating shaft 6 to rotate at high speed. The sand grinding disc 18 on the rotating shaft 6 rotates with the rotating shaft 6, which pushes the grinding media and pigment slurry in the cylinder 14 to move violently. The media breaks and refines the pigment particles through collision, friction and shearing, and disperses them evenly in the slurry. The refined pigment slurry moves towards the end of the cylinder 14 under the action of rotational power and enters the separation rotor 19 area. The separation rotor 19 rotates with the shaft 6 to generate centrifugal force, which throws the denser grinding media back into the cylinder 14, while the slurry enters the rotor through the opening 20 on the outer wall of the rotor, and is then filtered by the screen cylinder 21 (intercepting fine media particles), and finally discharged through the discharge pipe 23 to obtain qualified art painting pigments. When the abrasive needs to be removed, first stop the grinding operation, then place the storage box directly below the discharge end of the cylinder 14, then turn off the drive motor 9 and the diaphragm pump 11, open the cover plate 22 on one side of the cylinder 14, and clean the residual slurry; start the hydraulic cylinder 26 in the first support frame 1, the hydraulic cylinder 26 drives the piston rod to extend, push the lifting plate 27 to move upward along the guide rod 29, when the lifting plate 27 moves upward, it drives the push plate 28 to rotate around the pin shaft, the push plate 28 pushes the bottom plate 2 to tilt upward around the movable shaft 25, at this time the positioning protrusion 16 at the bottom of the bottom plate 2 disengages from the positioning groove 17 of the third support frame 24, and the limit is released; as the hydraulic cylinder 26 continues to drive, the cylinder 14 tilts with the bottom plate 2, and the grinding media in the cylinder 14 is automatically discharged into the storage box under the action of gravity; After the medium is discharged, the hydraulic cylinder 26 drives the piston rod to retract, causing the lifting plate 27 to descend. The push plate 28 pulls the bottom plate 2 to reset, and the positioning protrusion 16 is re-embedded into the positioning groove 17. The equipment returns to the horizontal working state. The cover plate 22 is closed, and new grinding media can be added to start the next round of grinding.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
