Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pigment grinding equipment, and in particular to a pigment grinding device for painting. Background Technology
[0002] The pigment grinding device consists of several key components: a grinder, grinding media, a hopper, and a separating device. The grinder is the core of the device, using rotating grinding media to finely grind the pigments, resulting in more uniform and delicate pigment particles. The hopper is used to hold the pigments and media to be ground. During the grinding process, the pigments are gradually crushed under the high-speed motion inside the grinder. The separating device is used to separate the ground pigments and media to collect the pure pigments. The entire device ensures that the pigments achieve the required fineness and uniformity by precisely controlling the speed and time, providing high-quality raw materials for the final painted effect.
[0003] A search revealed Chinese patent publication number CN218250524U, which discloses a pigment grinding device. A grinding roller is rotatably connected to a grinding frame. The grinding frame has scraping mechanisms at both axial ends of the grinding roller. The scraping mechanisms include scraper plates and scraper frames, with the scraper frames symmetrically positioned at both ends of the grinding frame. The scraper plates are mounted on the scraper frames, with their bottom surfaces close to the surface of the grinding roller. A cleaning block is slidably connected to the scraper plate. One end of the scraper plate has a groove, the size of which matches the groove. The scraper plate scrapes off residual pigment from the grinding roller surface during grinding, thereby improving grinding efficiency. The scraper plate's close contact with the grinding roller surface allows it to scrape off any adhering material into the grinding working surface of the roller, further improving grinding efficiency. The cleaning block removes residual pigment from the scraper plate, preventing pigment accumulation after prolonged use and ensuring proper pigment control. However, in actual use, the gap between the grinding rollers cannot be effectively adjusted, making it difficult to control the degree of pigment grinding. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a pigment grinding device, which aims to improve the problem in the prior art that the gap between the grinding rollers cannot be adjusted well, thus making it difficult to control the degree of pigment grinding.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pigment grinding device, comprising a trapezoidal base, a DC motor fixedly connected to the inner wall of the trapezoidal base, a gear fixedly connected to the output end of the DC motor, a hollow rotating grinding disc rotatably connected to the top center of the trapezoidal base, a gear ring fixedly connected to the outer side of the hollow rotating grinding disc, the gear meshing with the gear ring, multiple grinding grooves formed on the inner wall of the hollow rotating grinding disc, multiple wear-resistant blocks fixedly connected to the center of the inner wall of the hollow rotating grinding disc, and a U-shaped plate fixedly connected to the top of the trapezoidal base. The top of the U-shaped plate is provided with a threaded rod, and a valve handle is rotatably connected to the middle of the top of the U-shaped plate. The outer wall of the threaded rod passes through the U-shaped plate and is fixedly connected to a fixed grinding disc. The valve handle is threadedly connected to the outer wall of the threaded rod. The outer wall of the fixed grinding disc has multiple grinding grooves. Multiple grinding blocks are fixedly connected to the bottom of the fixed grinding disc. Limiting rods are fixedly connected to the left and right sides of the top of the fixed grinding disc. The outer walls of the two limiting rods pass through the U-shaped plate. A collection mechanism is provided at the bottom of the trapezoidal base. The collection mechanism is used to collect the pigment after grinding.
[0006] As a further description of the above technical solution:
[0007] The above technical solution works as follows: rotating the valve handle moves the threaded rod, which in turn moves the fixed grinding disc, adjusting the gap between the fixed grinding disc and the hollow rotating grinding disc. Limited by the limit rod, the fixed grinding disc can only move up and down. Then, starting the DC motor drives the gears, which mesh with a gear ring to rotate the hollow rotating grinding disc. The pigment to be ground is then placed on top of the hollow rotating grinding disc. Under the rotation and grinding of grinding tank one and grinding tank two, the pigment gradually becomes the desired state. Simultaneously, the wear-resistant block and grinding block further grind the pigment, improving the grinding pass rate. Finally, the pigment falls through the hollow part of the hollow rotating grinding disc.
[0008] The collection mechanism includes a collection box, which is slidably connected to the bottom of the trapezoidal base. The inner walls of the collection box are fixedly connected to the front and rear sides with fixing plates. A hollow frame is provided on the top of the two fixing plates. An inclined plate is fixedly connected to the inner wall of the hollow frame. The outer walls of the hollow frame are provided with notches on the left and right sides. The top of the inclined plate is provided with multiple filter holes.
[0009] The above technical solution works as follows: the ground pigment falling from the hollow part of the hollow rotating grinding disc first falls above the inclined plate. The pigment that meets the requirements can pass through the filter holes above and fall into the collection box, while the pigment that does not meet the requirements will gather towards the front of the hollow frame under the tilting action of the inclined plate. When the grinding is finished, the collection box is pulled out. At this time, the hollow frame is taken out through the notch, thereby removing all the pigment that did not pass through. The pigment that meets the requirements is in the collection box. Furthermore, by changing the filter holes of different sizes, pigments with different requirements can be screened.
[0010] As a further description of the above technical solution:
[0011] The outer wall of the trapezoidal base is fixedly connected to multiple pillars, and the bottom of each pillar is fixedly connected to a support foot.
[0012] The above technical solution allows the trapezoidal base to be supported by pillars, and the support feet to increase the contact with the ground, thereby reducing the damage to the ground during operation.
[0013] As a further description of the above technical solution:
[0014] A protective cover is fixedly connected to the top front side of the trapezoidal base, and a warning sign block is fixedly connected to the front side of the trapezoidal base.
[0015] The above technical solutions provide the following: the protective cover can prevent operators from being accidentally injured by the meshing of gears and gear rings, and the warning sign block can remind operators to pay attention to safety.
[0016] As a further description of the above technical solution:
[0017] An L-shaped column is fixedly connected to the top left side of the trapezoidal base, and a lighting lamp is fixedly connected to the right side of the L-shaped column.
[0018] The above technical solution provides additional lighting for operators through the use of lighting fixtures.
[0019] As a further description of the above technical solution:
[0020] The front left and right sides of the collection box are fixedly connected to fixed posts, and the front sides of the two fixed posts are rotatably connected to U-shaped handles.
[0021] The above technical solution allows for easy removal of the collection box via a U-shaped handle.
[0022] As a further description of the above technical solution:
[0023] An electrostatic eliminator is fixedly connected to the right side of the U-shaped plate, and an alarm is fixedly connected to the top of the U-shaped plate.
[0024] The above technical solution allows for the elimination of static electricity generated during the grinding process using an electrostatic eliminator, and the alert system to notify operators in case of malfunction.
[0025] As a further description of the above technical solution:
[0026] A hook is fixedly connected to the left side of the U-shaped plate, and a cleaning brush is provided on the outside of the hook.
[0027] The above technical solution allows for the hanging of a cleaning brush via a hook, which facilitates cleaning the surface of the device.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the threaded rod can be moved by rotating the valve handle, thereby adjusting the gap between the fixed grinding disc and the hollow rotating grinding disc. The limiting rod ensures that the grinding disc only moves up and down. After starting the DC motor, the gear drives the gear ring to rotate the hollow rotating grinding disc. Under the action of grinding groove one and grinding groove two, the pigment reaches the required state. The wear-resistant block and grinding block further grind the pigment. The ground pigment falls through the hollow part of the hollow rotating grinding disc, which can control the degree of pigment grinding.
[0030] 2. In this utility model, the pigment after grinding falls from the hollow part of the hollow grinding disc to the inclined plate. Qualified pigment enters the collection box through the filter hole, while unqualified pigment gathers on the front side of the inclined plate. After grinding is completed, the collection box is taken out, and the hollow frame is removed through the notch. The collection box contains qualified pigment. By changing the filter hole of different size, pigments of different specifications can be screened out. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a color pigment grinding device, comprising a trapezoidal base 1, a DC motor 3 fixedly connected to the inner wall of the trapezoidal base 1, a gear 4 fixedly connected to the output end of the DC motor 3, a hollow rotating grinding disc 6 rotatably connected to the top center of the trapezoidal base 1, a gear ring 5 fixedly connected to the outer side of the hollow rotating grinding disc 6, the gear 4 meshing with the gear ring 5, a plurality of grinding grooves 7 formed on the inner wall of the hollow rotating grinding disc 6, a plurality of wear-resistant blocks 8 fixedly connected to the center of the inner wall of the hollow rotating grinding disc 6, and a U-shaped plate 9 fixedly connected to the top of the trapezoidal base 1. A threaded rod 10 is provided, and a valve handle 14 is rotatably connected to the top center of the U-shaped plate 9. The outer wall of the threaded rod 10 passes through the U-shaped plate 9 and is fixedly connected to a fixed grinding disc 11. The valve handle 14 is threadedly connected to the outer wall of the threaded rod 10. Multiple grinding grooves 12 are opened on the outer wall of the fixed grinding disc 11. Multiple grinding blocks 13 are fixedly connected to the bottom of the fixed grinding disc 11. Limiting rods 15 are fixedly connected to the left and right sides of the top of the fixed grinding disc 11. The outer walls of the two limiting rods 15 pass through the U-shaped plate 9. A collection mechanism 2 is provided at the bottom of the trapezoidal base 1. The collection mechanism 2 is used to collect the pigment after grinding.
[0041] Specifically, rotating the valve handle 14 moves the threaded rod 10, which in turn moves the fixed grinding disc 11, adjusting the gap between the fixed grinding disc 11 and the hollow rotating grinding disc 6. Limiting the movement with the limit rod 15, the fixed grinding disc 11 can only move up and down. Then, starting the DC motor 3 drives the gear 4 to rotate. The gear 4 meshes with the gear ring 5, causing the gear ring 5 to rotate the hollow rotating grinding disc 6. At this point, the pigment to be ground is simply placed into the top of the hollow rotating grinding disc 6. Under the rotational grinding of the first grinding tank 7 and the second grinding tank 12, the pigment gradually becomes the desired state. Simultaneously, the wear-resistant block 8 and the grinding block 13 further grind the pigment, improving the grinding pass rate. The pigment then falls through the hollow part of the hollow rotating grinding disc 6.
[0042] Reference Figure 2 , Figure 3 and Figure 6 The collection mechanism 2 includes a collection box 201, which is slidably connected to the bottom of the trapezoidal base 1. The inner wall of the collection box 201 is fixedly connected to the front and rear sides of the inner wall with a fixing plate 202. A hollow frame 203 is provided on the top of the two fixing plates 202. An inclined plate 204 is fixedly connected to the inner wall of the hollow frame 203. A notch 205 is provided on the left and right sides of the outer wall of the hollow frame 203. A plurality of filter holes 206 are provided on the top of the inclined plate 204.
[0043] Specifically, the ground pigment falling from the hollow part of the hollow rotating grinding disc 6 first falls above the inclined plate 204. The pigment that meets the requirements can pass through the filter hole 206 above and fall into the collection box 201, while the pigment that does not meet the requirements will gather in front of the hollow frame 203 under the tilting action of the inclined plate 204. When the grinding is finished, the collection box 201 is pulled out. At this time, the hollow frame 203 is taken out through the notch 205, thereby removing all the pigment that did not pass through. The pigment in the collection box 201 is the pigment that meets the requirements. Furthermore, by changing the filter hole 206 of different sizes, pigments of different requirements can be screened.
[0044] Reference Figure 1 , Figure 2 and Figure 3 Multiple pillars 16 are fixedly connected to the outer wall of the trapezoidal base 1. Support feet 17 are fixedly connected to the bottom of the pillars 16. A protective cover 18 is fixedly connected to the front top of the trapezoidal base 1. A warning sign block 19 is fixedly connected to the front side of the trapezoidal base 1. An L-shaped column 20 is fixedly connected to the left top of the trapezoidal base 1. A lighting lamp 21 is fixedly connected to the right side of the L-shaped column 20.
[0045] Specifically, the support column 16 can support the trapezoidal base 1, the support foot 17 can increase the contact with the ground, thus reducing the damage to the ground when the device is running, the protective cover 18 can prevent the operator from being accidentally injured by the engagement of the gear 4 and the gear ring 5, the warning sign block 19 can remind the operator to pay attention to safety, and the lighting lamp 21 can provide additional lighting for the operator.
[0046] Reference Figure 1 , Figure 2 and Figure 3 The front left and right sides of the collection box 201 are fixedly connected to the fixing posts 22. The front sides of the two fixing posts 22 are rotatably connected to the U-shaped handles 23. The right side of the U-shaped plate 9 is fixedly connected to the static eliminator 24. The top of the U-shaped plate 9 is fixedly connected to the alarm 25. The left side of the U-shaped plate 9 is fixedly connected to the hook 26. The outside of the hook 26 is provided with a cleaning brush 27.
[0047] Specifically, the U-shaped handle 23 makes it easy to pull out the collection box 201, and the rotation of the fixed column 22 reduces the space occupied by the U-shaped handle 23 on the horizontal plane. The static eliminator 24 can eliminate static electricity generated during the grinding process. The alarm 25 can remind the operator when a malfunction occurs. The hook 26 can hang the cleaning brush 27, which can facilitate cleaning the surface of the device.
[0048] Working Principle: Before using the device, firstly, rotating the valve handle 14 drives the threaded rod 10 to move. The displacement of the threaded rod 10 then causes the fixed grinding disc 11 to move, adjusting the gap between the fixed grinding disc 11 and the hollow rotating grinding disc 6. Under the constraint of the limit rod 15, the fixed grinding disc 11 can only move vertically. After starting the DC motor 3, the gear 4 rotates and meshes with the gear ring 5, thereby driving the hollow rotating grinding disc 6 to rotate. The pigment to be ground is put into the top of the hollow rotating grinding disc 6. Under the synergistic action of the first grinding tank 7 and the second grinding tank 12, the pigment gradually reaches the desired state. The wear-resistant block 8 and the grinding block 13 further refine the pigment to improve the grinding qualification rate. Finally, the ground pigment passes through the hollow grinding disc 6. The pigment discharged from the hollow part of the rotating grinding disc 6 and collected by the collection mechanism 2 falls from the hollow part of the hollow rotating grinding disc 6 and first settles on the upper end of the inclined plate 204. Then, it passes through the filter hole 206 above the inclined plate 204. Only pigments that meet the standards can pass through and fall into the collection box 201. Pigments that do not meet the standards accumulate on the front side of the hollow frame 203 due to the tilting effect of the inclined plate 204. After the grinding process is completed, the collection box 201 can be pulled out and the hollow frame 203 can be removed through the notch 205, thereby removing all pigments that have not passed the screening. The pigments retained in the collection box 201 are the products that meet the requirements. In addition, by changing the filter hole 206 of different sizes, pigments of different specifications can be screened.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
