Description

Technical Field

[0001] This utility model relates to the field of pigment grinding technology, and in particular to a novel and efficient pigment grinding device. Background Technology

[0002] Pigments are substances that can color objects. They are indispensable raw materials for manufacturing paints, inks, oil paint pastes, cosmetic paints, colored paper, etc. However, in the process of using organic pigments, it is required that they have fine particle size and uniform particle size distribution, which necessitates grinding and dispersing the organic pigments.

[0003] The prior art, with publication number CN221514658U, discloses a pigment grinding device for art teaching, including a base. A side plate is fixedly connected to one side of the top of the base. A grinding mechanism for grinding pigments is rotatably connected to the top of the side plate. A power mechanism for driving the grinding is provided on the grinding mechanism. A drive mechanism for driving the grinding mechanism to reciprocate is provided on one side of the side plate and below the grinding mechanism. Two sets of positioning mechanisms for limiting the position of the pigment bucket are fixedly installed on the top of the base.

[0004] In actual use, the pigment is ground only by the grinding roller, which has low grinding efficiency. Moreover, the grinding roller and grinding cylinder are usually set in fixed positions, so the grinding gap formed between them cannot be adjusted. Therefore, it is not possible to grind the pigment to different degrees of fineness. Therefore, it is necessary to design a new type of high-efficiency pigment grinding device to solve the above problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a new and efficient pigment grinding device to solve the above-mentioned problems.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel high-efficiency pigment grinding device, comprising: A grinding tank, on which a pigment grinding mechanism is provided; The pigment grinding mechanism includes a power motor, a rotating shaft one, a grinding roller one, a rotating shaft two, a grinding roller two, a connecting piece, a grinding cylinder two, a grinding cylinder one, and a pulverizing blade; The power motor is fixedly installed on the top of the grinding tank. The output end of the power motor is fixedly connected to the first rotating shaft. The first grinding roller is fixedly installed between the first rotating shaft and the second rotating shaft. The bottom of the second rotating shaft is fixedly connected to the second grinding roller. The connecting piece is fixedly connected to the second grinding cylinder. The first grinding cylinder is fixedly installed on the inner wall of the top of the grinding tank. The crushing blade is fixedly installed on the outside of the first rotating shaft.

[0008] A further feature of this invention is that the pigment grinding mechanism includes a top plate, a three-way feeding pipe, a pigment adding hopper, a threaded sleeve, and a clamping screw. The top plate is fixedly installed on the top of the connector, the three-way feeding pipe is fixedly installed on the grinding tank, the pigment adding hopper is fixedly installed on the three-way feeding pipe, the threaded sleeve is threaded onto the outside of the three-way feeding pipe, and the clamping screw is threaded onto the threaded sleeve, with the clamping screw abutting against the top plate.

[0009] A further feature of this invention is that a feed pipe is fixedly installed at the bottom of the grinding tank.

[0010] By adopting the above technical solution, it is convenient to process the ground pigments into feed.

[0011] A further feature of this invention is that a support frame is fixedly installed at the bottom of the grinding tank.

[0012] A further feature of this invention is that a movable hole is provided at the top of the grinding tank, and the connecting piece is vertically slidably installed in the movable hole.

[0013] By adopting the above technical solution, the connector can be moved vertically.

[0014] A further feature of this invention is that the top plate is slidably sleeved on the outside of the three-way feeding pipe.

[0015] By adopting the above technical solution, the top plate can be moved vertically.

[0016] A further feature of this invention is that the top plate is in contact with two threaded sleeves.

[0017] A further feature of this invention is that the pulverizing blade is located inside the grinding cylinder.

[0018] The beneficial effects of this utility model are: This invention utilizes a pigment grinding mechanism to first break down blocky, coarse pigment particles into fine particles using a crushing blade inside a grinding cylinder. This avoids the problem of high grinding resistance and low efficiency caused by coarse particles directly entering the grinding process. Then, a first grinding roller works in conjunction with a first grinding cylinder to complete the first-stage grinding, initially refining the pigment particle size. Finally, a second-stage fine grinding is performed by a second grinding roller and a second grinding cylinder. This multi-stage process can significantly shorten the time it takes for the pigment to reach the target fineness and significantly improve grinding efficiency. This invention uses a pigment grinding mechanism to drive the second grinding cylinder to move vertically, precisely adjusting the width of the grinding gap between the second grinding cylinder and the second grinding roller. When coarser pigment is needed, the grinding gap is widened; when fine grinding is required, the grinding gap is narrowed, solving the problem of fixed grinding gaps in traditional devices that cannot adapt to different fineness requirements.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a novel and efficient pigment grinding device, comprising: The grinding tank 1 is equipped with a pigment grinding mechanism. It should be noted that the pigment can be crushed and then subjected to multi-stage grinding, which can effectively improve the pigment grinding efficiency. Moreover, the grinding gap between the grinding roller 2 6 and the grinding cylinder 2 8 can be adjusted to grind the pigment to different degrees of fineness. The pigment grinding mechanism includes a power motor 2, a rotating shaft 3, a grinding roller 4, a rotating shaft 2 5, a grinding roller 2 6, a connecting piece 7, a grinding cylinder 2 8, a grinding cylinder 1 14, and a pulverizing blade 15; The power motor 2 is fixedly installed on the top of the grinding tank 1. The output end of the power motor 2 is fixedly connected to the rotating shaft 3. The grinding roller 4 is fixedly installed between the rotating shaft 3 and the rotating shaft 5. The bottom of the rotating shaft 5 is fixedly connected to the grinding roller 6. The connecting piece 7 is fixedly connected to the grinding cylinder 8. The grinding cylinder 14 is fixedly installed on the top inner wall of the grinding tank 1. The crushing blade 15 is fixedly installed on the outside of the rotating shaft 3.

[0028] With the above structure, starting the power motor 2 can cause the rotating shaft 3 to drive the grinding roller 4 and the crushing blade 15 to rotate. The pigment enters through the three-way feeding pipe 10. The crushing blade 15 performs preliminary crushing treatment on the pigment. Then, the grinding roller 4 and the grinding cylinder 14 cooperate to perform preliminary grinding treatment on the pigment. The pigment after preliminary grinding will be further ground by the grinding roller 6 and the grinding cylinder 8, which effectively improves the pigment grinding efficiency and grinding effect. In addition, by vertically moving the grinding cylinder 8, the distance between the grinding cylinder 8 and the grinding roller 6 can be adjusted, which can adjust the grinding gap between the grinding roller 6 and the grinding cylinder 8, and can grind the pigment to different degrees of fineness.

[0029] Specifically, the pigment grinding mechanism also includes a top plate 9, a three-way feeding pipe 10, a pigment adding hopper 11, a threaded sleeve 12, and a clamping screw 13. The top plate 9 is fixedly installed on the top of the connector 7, the three-way feeding pipe 10 is fixedly installed on the grinding tank 1, the pigment adding hopper 11 is fixedly installed on the three-way feeding pipe 10, the threaded sleeve 12 is threadedly sleeved on the outside of the three-way feeding pipe 10, and the clamping screw 13 is threadedly installed on the threaded sleeve 12 and abuts against the top plate 9.

[0030] With the above structure, first rotate one threaded sleeve 12, then move the top plate 9 to adjust the position of the grinding cylinder 8, then rotate the other threaded sleeve 12 to lock the top plate 9, and then rotate the clamping screw 13 to clamp the clamping screw 13 against the top plate 9, thereby improving the stability of the threaded sleeve 12.

[0031] Specifically, a feed pipe 16 is fixedly installed at the bottom of the grinding tank 1, and a support frame is fixedly installed at the bottom of the grinding tank 1. It should be noted that the grinding tank 1 can be supported.

[0032] Specifically, the grinding tank 1 has a moving hole at the top, and the connector 7 is vertically slidably installed in the moving hole. It should be noted that this allows the connector 7 to move stably in the vertical direction.

[0033] Specifically, the top plate 9 is slidably sleeved on the outside of the three-way feeding pipe 10, and the top plate 9 is in contact with the two threaded sleeves 12. It should be noted that the position of the top plate 9 can be adjusted by rotating the position of the two threaded sleeves 12.

[0034] Specifically, the pulverizing blade 15 is located inside the grinding cylinder 14. It should be noted that the pigment added to the grinding cylinder 14 can be pulverized.

[0035] Working principle: S1: According to the fineness requirements of the pigment to be ground, first rotate one of the threaded sleeves 12 on the outside of the three-way feeding pipe 10, so that it moves along the axial direction of the three-way feeding pipe 10. Since the top plate 9 is slidably sleeved on the outside of the three-way feeding pipe 10 and in contact with the threaded sleeve 12, the movement of the threaded sleeve 12 will push or pull the top plate 9 to move vertically in sync. The top plate 9 is fixedly connected to the second grinding cylinder 8 through the connector 7, thereby driving the second grinding cylinder 8 to slide vertically along the moving hole at the top of the grinding tank 1, adjusting the distance between the second grinding cylinder 8 and the second grinding roller 6 below, i.e. the grinding gap. When the grinding gap reaches the preset width, rotate the other threaded sleeve 12, so that it is in close contact with the other side of the top plate 9, forming a bidirectional clamping limit on the top plate 9; finally, rotate the clamping screws 13 on the two threaded sleeves 12, so that the end of the clamping screws 13 is in close contact with the surface of the top plate 9, further locking the position of the top plate 9 and the second grinding cylinder 8, and preventing the grinding gap from shifting during the grinding process; S2: After confirming that the grinding gap adjustment is completed, pour the block or coarse pigment to be ground into the pigment addition hopper 11. The pigment is transported to the grinding cylinder 14 inside the grinding tank 1 through the three-way feeding pipe 10 to prepare for the subsequent grinding process. Start the power motor 2 at the top of the grinding tank 1. The output end of the power motor 2 drives the rotating shaft 3 to rotate at high speed. Since the crushing blade 15 is fixedly installed on the outside of the rotating shaft 3 and located inside the grinding cylinder 14, the rotation of the rotating shaft 3 will drive the crushing blade 15 to rotate synchronously. During the rotation, the crushing blade 15 impacts and cuts the coarse pigment in the grinding cylinder 14, crushing the block pigment into fine particles, completing the pretreatment, laying the foundation for the subsequent fine grinding, and avoiding the coarse particles from directly entering the grinding process, which would lead to low grinding efficiency or wear of the grinding parts. S3: While rotating shaft 3 drives the grinding blade 15 to rotate, it also drives the grinding roller 4 fixedly connected to its bottom to rotate synchronously. The fine pigment particles, which have been pre-treated by the grinding blade 15, will fall from the gap of the grinding cylinder 14 into the area between the grinding roller 4 and the inner wall of the grinding cylinder 14. When the grinding roller 4 rotates at high speed, it forms relative motion with the fixed inner wall of the grinding cylinder 14, and performs primary grinding on the pigment particles through squeezing and shearing action, further refining the pigment particles to achieve a preliminary uniform particle size. The bottom of the rotating shaft 3 is fixedly connected to the grinding roller 6 through the rotating shaft 2 5. Therefore, when the grinding roller 4 rotates, it will drive the rotating shaft 5 and the grinding roller 6 to rotate synchronously. The pigment that has been ground in the first stage will fall naturally into the grinding gap between the grinding cylinder 8 and the grinding roller 6 under the action of gravity. Since the grinding cylinder 8 has been fixed in the preset position through the previous adjustment, the high-speed rotating grinding roller 6 and the fixed inner wall of the grinding cylinder 8 form a secondary squeezing and shearing action to perform secondary fine grinding of the pigment. Compared with the first stage of grinding, the grinding gap of the second stage of grinding can be flexibly adjusted according to the needs, which can grind the pigment to a finer and more uniform particle size to meet different fineness requirements.

[0036] The present invention provides a detailed description of a novel and efficient pigment grinding device. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
