A grinding device for producing water-based ink

Abstract

The present invention relates to the technical field related to pulverizing equipment, and discloses a grinding device for water-based ink production. In order to solve the problem that the material fineness cannot meet the standard due to the short grinding channel, a plurality of material retaining plates are equidistantly fixed through the inner side of the grinding cylinder, and a dispersion plate located between the distances between adjacent material retaining plates is fixedly installed on the driving cylinder. When the water-based ink raw materials and grinding media are added to the inner side of the grinding cylinder from the feed pipe, the dispersion plate is used to drive the grinding media to grind and refine the raw materials. At the same time, the ink raw materials and the grinding media will move according to the curved channel formed between the material retaining plate and the dispersion plate, thereby extending the grinding channel, increasing the grinding time of the ink raw materials, and making the ground ink fineness reach the required level, thereby finally achieving the effect of extending the water-based ink grinding channel and improving the ink fineness.

Description

Technical Field

[0001] The present invention relates to the technical field related to pulverizing equipment, and in particular to a grinding device for producing water-based ink. Background Art

[0002] In the manufacturing process of water-based ink, the grinding process undoubtedly plays a pivotal role. The core task of this process is not only to achieve comprehensive and uniform mixing of the key components of water-based ink (such as pigments, resins, various additives and water as a solvent), but also to refine the particles of these components to an ideal size range, thereby ensuring that the finished ink has excellent characteristics such as uniform color, strong adhesion and good fluidity.

[0003] At present, the sand mill is the main equipment in the grinding process. Its working principle mainly relies on the rotation of the dispersion plate to drive the movement of the grinding media (commonly including zirconium beads, steel beads or glass beads, etc.). These grinding beads rotate at a very high speed inside the sand mill and collide with each other, exerting great pressure and shear force on the material (especially the pigment particles in water-based ink). This strong mechanical action can effectively crush and refine the material particles until the predetermined particle size requirements are reached.

[0004] However, in practical applications, sand mills also face some challenges. In particular, due to the relatively fixed length of its grinding barrel, the channel length of the water-based ink during the grinding process is limited, which in turn limits the grinding stroke, making it difficult to achieve the best grinding efficiency and effect. This limitation not only affects the degree of particle refinement, but may also increase the difficulty and burden of fine filtering of water-based ink by the filter in the subsequent processing stage. Summary of the invention

[0005] The present invention provides a grinding device for water-based ink production, which has the advantage of extending the grinding channel of the water-based ink, and is used to solve the problem in the above background technology that the short grinding channel leads to the failure of the material fineness to meet the standard.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a grinding device for producing water-based ink, comprising: a machine base, a gearbox driven by a main motor is fixedly installed on the top, a driving cylinder is fixedly installed on the outer side of the output shaft of the gearbox, and the main motor is controlled by a main control computer for speed control; a grinding cylinder, fixed on the machine base, and a cylinder cover is fixedly installed on the end of the grinding cylinder; a feed pipe, fixed on one side of the grinding cylinder, and used for inputting ink raw materials and grinding media into the grinding cylinder; a material baffle, fixed on the inner side of the grinding cylinder; a dispersion plate, installed on the outer side of the driving cylinder and located between the material baffle plates; a dispersion baffle and a gathering baffle, the dispersion baffle is fixed at one end of the dispersion plate, and is used for conveying the ink raw materials and grinding media toward the inner wall of the grinding cylinder; the gathering baffle is located at the other end of the dispersion plate, and is used for conveying the ink raw materials and grinding media on the inner wall of the grinding cylinder to the middle, and then to the next dispersion plate, so as to increase the grinding path of the ink raw materials and grinding media in the grinding cylinder.

[0007] Furthermore, the material blocking plate is in the shape of a cylinder with a through middle portion, and there are multiple material blocking plates, and the multiple material blocking plates are equidistantly fixed on the inner side of the grinding cylinder.

[0008] Furthermore, the inner wall of the grinding cylinder is tapered, so that the grinding media tends to move downward after impact.

[0009] Furthermore, a filter cartridge and a discharge pipe are installed on the cartridge cover.

[0010] Furthermore, a support rod located in the inner cavity of the driving cylinder is fixedly installed at the end of the cylinder cover, and a driven shaft is movably installed on the outer side of the support rod, one end of the driven shaft is fixedly connected to the filter cylinder, and the other end is fixedly installed with a driven gear; a driving ring gear is provided on the inner side of the driving cylinder, and an intermediate gear meshing with the driven gear and the driving ring gear is movably installed at the end of the support rod.

[0011] Furthermore, a recovery disk is fixedly installed at the end of the filter cartridge to transport the grinding medium inside the grinding cartridge toward the filter cartridge.

[0012] Furthermore, an auger is fixedly installed on the outer side of the driven shaft, and a ball discharge groove is opened on the outer side of the driving cylinder.

[0013] Furthermore, the dispersion disc is movably installed on the outside of the driving cylinder, and a detection tension spring is connected between the driving cylinder and the dispersion disc; a bead blocking ring sleeve is movably installed on the outside of the driving cylinder, and a telescopic blocking rod is connected between the bead blocking ring sleeve and the dispersion disc, and a reset spring located inside the telescopic blocking rod is fixedly connected between the dispersion disc and the bead blocking ring sleeve; a guide rod is fixedly installed on the bead blocking ring sleeve, and a bead filling groove is opened on the outside of the driving cylinder; an air avoidance ring groove is arranged on the outside of the driven shaft rod, and a reset push plate and a bead filling push plate are arranged on the outside of the driven shaft rod and in the area of ​​the air avoidance ring groove.

[0014] Furthermore, the reset push plate and the bead filling push plate are distributed in an "eight" shape.

[0015] The present invention has the following beneficial effects: The present invention provides a grinding device for producing water-based ink, in which a plurality of blocking discs are fixedly installed at equal distances on the inner wall of a grinding cylinder. These blocking discs not only play a role of blocking and guiding, but also cleverly cooperate with the dispersion discs fixedly installed on a driving cylinder to form a unique grinding area located between the spacings of adjacent blocking discs. The dispersion discs are precisely placed in these areas, and the design is intended to maximize the use of space and improve grinding efficiency.

[0016] When the raw materials of water-based ink and grinding media (such as zirconium beads, glass beads, etc.) are introduced into one side of the grinding cylinder through the feed pipe, the dispersion disc begins to play its key role. It uses the centrifugal force generated by rotation to drive the grinding media to violently impact and shear the ink raw materials, thereby achieving the grinding and refinement of the raw materials. In this process, the interaction between the grinding media and the ink raw materials not only promotes the refinement of particles, but also ensures the uniform mixing of the ink components.

[0017] What is even more ingenious is that a series of curved channels are formed between the retaining plate and the dispersion plate. These channels not only guide the ink raw materials and grinding media to move in an orderly manner in the grinding cylinder, but also significantly extend their grinding paths. By increasing the length of the grinding channels, the device provides more sufficient grinding time for the ink raw materials, thereby ensuring that the fineness of the ground ink can meet the predetermined standards.

[0018] In summary, this grinding device for water-based ink production has successfully achieved the extension of the grinding channel and the improvement of ink fineness through its unique design. This innovation not only improves grinding efficiency and quality, but also brings a more refined and controllable grinding effect to the production of water-based ink, meeting the market's growing demand for high-quality water-based ink.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] This application aims to extend the grinding channel for ink raw materials. As an example of this application, please refer to Figure 1It can be seen that the grinding device mainly uses the machine base 1 to firmly support the whole. The main motor 2 is fastened to the top of the machine base 1 by bolts, and the gearbox 3 can be driven by the main motor 2 to work. Figure 3 As shown, a drive cylinder 13 is fixedly mounted on the outer side of the output shaft 300 of the gearbox 3, so as to ensure that when the main motor 2 starts working, the gearbox 3 can transmit power to the drive cylinder 13 and realize the rotation of the drive cylinder 13. The main motor 2 is generally controlled by a main control computer 4 fixed on the surface of the base 1, so that the speed of the main motor 2 can be adjusted as needed.

[0024] The grinding cylinder 5 is fixed to the machine base 1 by bolts. Figure 2 and Figure 3 As shown, the driving cylinder 13 is located in the inner cavity of the grinding cylinder 5, and the grinding cylinder 5 and the driving cylinder 13 need to be coaxially arranged. The end of the grinding cylinder 5 is provided with a cylinder cover 6 connected by bolts, and the cylinder cover 6 can be used to block the inner cavity of the grinding cylinder 5 to form a relatively closed space. The feed pipe 7 is fixedly installed on one side of the grinding cylinder 5. The feed pipe 7 can be used to add ink raw materials (such as pigments, resins, various additives and water as a solvent) and grinding media 14 (such as zirconium beads, steel beads or glass beads, etc.) into the inner cavity of the grinding cylinder 5. The dispersion disk 9 installed on the outside of the driving cylinder 13 is used to make the grinding media 14 move toward the inner wall of the grinding cylinder 5, and the grinding of the ink raw materials is achieved through the extrusion and shear force between the grinding media 14. This method is a conventional grinding method at present, and its defect is that the grinding channel is limited by the length of the grinding cylinder 5, resulting in a short channel length, and the fineness of the ground ink raw materials cannot meet the required requirements.

[0025] Different from the prior art, Figure 2-Figure 4 It can be seen that a material blocking plate 10 is fixedly installed inside the grinding cylinder 5. The material blocking plate 10 is in the shape of a cylinder with a through middle. Generally speaking, there are multiple material blocking plates 10, and multiple material blocking plates 10 are fixed on the inner side of the grinding cylinder 5 at equal distances. Correspondingly, multiple dispersion plates 9 are installed outside the driving cylinder 13, and the dispersion plates 9 are arranged correspondingly between the spacings of adjacent material blocking plates 10. On this basis, from Figure 8 and Fig. 9 It can be seen that a plurality of dispersion bars 900 distributed at equal angles in a ring shape are fixedly installed at one end of the dispersion disk 9. The dispersion bars 900 are in the shape of a rectangular parallelepiped and face the central axis of the dispersion disk 9. A plurality of gathering bars 901 arranged at equal angles are fixedly installed at the other end of the dispersion disk 9. Unlike the dispersion bars 900, the gathering bars 901 are not directed toward the center line of the dispersion disk 9, which results in the gathering bars 901 being relatively tiltedly installed at the end of the dispersion disk 9.

[0026] In the actual application process, the grinding media 14 and the ink raw materials are added to the inner cavity of the grinding cylinder 5 through the feed pipe 7, and the main control computer 4 controls the main motor 2 to rotate, so that the output shaft 300 of the gearbox 3 drives the driving cylinder 13 to rotate synchronously, and the driving cylinder 13 drives the dispersion disk 9 to rotate synchronously, and the dispersion baffle 900 and the gathering baffle 901 will also rotate accordingly. Afterwards, under the rotation of the dispersion baffle 900, the grinding media 14 added to the inner cavity of the grinding cylinder 5 is swung toward the inner wall of the grinding cylinder 5, and the pressure and shear force between the grinding media 14 are used to grind and refine the ink raw materials.

[0027] When the grinding medium 14 hits the inside of the grinding cylinder 5, Figure 3 and Figure 4 It can be seen that the inner wall of the grinding cylinder 5 is tapered, and the length of the inner part close to the feed pipe 7 from the driving cylinder 13 is greater than the length of the other end from the driving cylinder 13, which will cause the grinding medium 14 to have a tendency to move to the right after hitting the inclined inner wall of the grinding cylinder 5; at the same time, the gathering baffle 901 will make the grinding medium 14 close to the inner wall of the grinding cylinder 5 be transported to the outer side of the driving cylinder 13 when following the rotation of the dispersion disk 9, and after passing the middle part of the baffle disk 10, the grinding medium 14 will be transported to the next dispersion baffle 900, and the cycle will be repeated so that the moving path of the grinding medium 14 and the ink raw material is relatively extended, as shown in FIG. Fig.14 shown.

[0028] When the grinding media 14 and the ink raw material are transported to the direction close to the cylinder cover 6, as shown in FIG. Figure 3 , Figure 4 and Fig.14 It can be seen that the grinding medium 14 and the ink raw material are filtered by the filter cartridge 17 movably installed on the cylinder cover 6, and the ink raw material that meets the refinement requirements is discharged outward from the discharge pipe 8 fixed on the cylinder cover 6. At this point, the grinding and refinement work of the ink raw material is completed.

[0029] The second embodiment is a further improvement on the basis of the first embodiment. Figure 4 , Figure 6 and Fig.11 It can be seen that a support rod 16 located in the inner cavity of the driving cylinder 13 is fixedly installed at the end of the cylinder cover 6. In addition, the driven shaft 15 is movably installed on the outer side of the support rod 16. Fig.12 As shown, one end of the driven shaft 15 is fixedly connected to the filter cartridge 17, and the other end is fixedly mounted with a driven gear 19 coaxially arranged with the support rod 16. Figure 4 , Figure 6 , Fig.10 and Fig.11It can be seen that a driving ring gear 132 is provided inside the driving cylinder 13, and an intermediate gear 18 meshing with the driven gear 19 and the driving ring gear 132 is movably installed at the end of the support rod 16. The transmission of the intermediate gear 18 makes the driving cylinder 13 rotate and drives the driven gear 19 to rotate synchronously. As mentioned above, the driven gear 19 is fixed to the end of the driven shaft 15, and the end of the driven shaft 15 is fixedly connected to the filter cylinder 17. Therefore, when the driving cylinder 13 rotates, the filter cylinder 17 will also rotate in the opposite direction. Since the filter cylinder 17 generally uses filter holes or filter grooves for filtering, as the ink continues to pass through the filter cylinder 17, the filter cylinder 17 will be blocked. Using the method provided in the second embodiment, while the driving cylinder 13 rotates, the filter cylinder 17 is forced to rotate in the opposite direction synchronously, and finally the ink raw materials blocked on the outside of the filter cylinder 17 are thrown out, so as to avoid the problem that the ink raw materials continue to accumulate on the outside of the filter cylinder 17 and cannot be filtered.

[0030] Moreover, combined with Figure 4 and Fig.12 It can be seen that a recovery plate 12 is fixedly installed at the end of the filter cartridge 17. When the recovery plate 12 rotates, the grinding medium 14 on the right side of the grinding cylinder 5 can be transported toward the filter cartridge 17. The principle is the same as the way the gathering baffle 901 transports the grinding medium 14. Finally, the grinding medium 14 will collide with the filter cartridge 17. On the one hand, the rotation of the filter cartridge 17 is used to clear the blockage. On the other hand, the impact of the grinding medium 14 on the filter cartridge 17 can further prevent the ink raw materials from gathering on the outside of the filter cartridge 17. On this basis, Figure 4 , Figure 5 and Fig.13 As shown, after the grinding medium 14 is transported toward the filter cartridge 17, it will eventually move to the area between the outside of the driven shaft 15 and the inside of the driving cylinder 13. Moreover, when the grinding medium 14 passes through the outside of the filter cartridge 17, it also has a tendency to push the ink raw materials gathered on the outside of the filter cartridge 17 to this area. On this basis, an auger 151 is fixedly installed on the outside of the driven shaft 15. When the auger 151 rotates with the driven shaft 15, the grinding medium 14 can be transported to the left. Figure 4 , Figure 5 and Fig.10 As shown, a ball discharge groove 131 is provided on the outer side of the driving cylinder 13 and is located in the same area as the feed pipe 7. After the auger 151 discharges the grinding medium 14 and the ink raw material from the ball discharge groove 131, secondary grinding will be performed again according to the path described in Example 1, thereby further refining the ink raw material.

[0031] In actual application, the grinding media 14 and ink raw materials are added into the inner cavity of the grinding cylinder 5 through the feed pipe 7, and the ink raw materials are ground during the rotation of the driving cylinder 13. Moreover, the rotation of the driving cylinder 13 forces the filter cylinder 17 to rotate in the opposite direction.

[0032] The grinding media 14 and ink raw materials moved to the right side of the grinding cylinder 5 are impacted to the outer side of the filter cylinder 17 by the rotation of the recovery disk 12, and the ink raw materials with the fineness are filtered by the filter cylinder 17, so that the ink raw materials with the fineness are discharged from the discharge pipe 8. The rotating filter cylinder 17 can prevent clogging, and when the grinding media 14 passes through the outer side of the filter cylinder 17, the ink raw materials filtered by the filter cylinder 17 can be pushed into the driving cylinder 13, and under the conveyance of the auger 151, the grinding media 14 and the filtered ink raw materials are discharged from the bead discharge groove 131, and then pass through the dispersion disk 9 again to complete the secondary grinding of the ink raw materials.

[0033] The third embodiment is a further improvement on the basis of the second embodiment. Figure 4 and Figure 5 It can be seen that the dispersion disc 9 is movably mounted on the outside of the driving cylinder 13, and a detection tension spring 902 is connected between the driving cylinder 13 and the dispersion disc 9. Under the elastic force of the detection tension spring 902, the gathering stop bar 901 is normally pressed against the material stop disc 10. At this time, the distance between the dispersion disc 9 and the material stop disc 10 is relatively smaller than the ball diameter of the grinding medium 14. Figure 4 and Fig. 9 As shown, an angle is set on the end of the outer side of the dispersion disk 9 and located on the side of the gathering baffle 901. When the gathering baffle 901 pushes the grinding medium 14 through the angle and moves between the dispersion disk 9 and the baffle disk 10, the grinding medium 14 will push the dispersion disk 9 to move away from the baffle disk 10 and elastically stretch the detection tension spring 902.

[0034] Correspondingly, the combination Figure 4 , Figure 7 , Fig. 9 and Fig.10 It can be seen that a bead retaining ring 11 is movably mounted on the outside of the driving cylinder 13, and the bead retaining ring 11 and the dispersion disk 9 are connected by a telescopic retaining rod 22. The telescopic retaining rod 22 can be axially retracted, and three telescopic retaining rods 22 are mounted on one telescopic retaining rod 22. The three telescopic retaining rods 22 are distributed in a ring with equal angles. By guiding the telescopic retaining rod 22, the bead retaining ring 11 and the dispersion disk 9 can only move away from / close to each other. A reset spring 221 located inside the telescopic retaining rod 22 is fixedly connected between the dispersion disk 9 and the bead retaining ring 11. A guide rod 111 is fixedly mounted on the bead retaining ring 11, and correspondingly, a bead replenishing groove 133 is provided on the outside of the driving cylinder 13. On the one hand, the bead replenishing groove 133 can limit the movement range of the guide rod 111, and on the other hand, the grinding medium 14 inside the driving cylinder 13 can be directly transported to the vicinity of the dispersion disk 9 through the bead replenishing groove 133, so as to achieve the purpose of replenishment on demand.

[0035] On this basis, combined with Figure 4 , Figure 5 and Fig.12It can be seen that the outer side of the driven shaft 15 is equidistantly arranged with air-avoiding annular grooves 150, and the air-avoiding annular grooves 150 correspond to the bead filling groove 133. The advantage of this design is that since the air-avoiding annular grooves 150 do not contain auger 151, when the auger 151 is used to transport the grinding medium 14, the grinding medium 14 that reaches the air-avoiding annular groove 150 is not continuously pushed forward by the auger 151, and the grinding medium 14 will be relatively gathered here, so as to be discharged from the bead filling groove 133 later. The reset push plate 20 and the bead filling push plate 21 are arranged on the outer side of the driven shaft 15 and in the area of ​​the air-avoiding annular groove 150, so that the grinding medium 14 can be discharged from the bead filling groove 133. Fig.13 It can be seen that the reset push plate 20 and the bead filling push plate 21 are arranged in an "eight" shape. The advantages of this arrangement are: The grinding medium 14 and ink raw materials are fed into the inner cavity of the grinding cylinder 5 through the feed pipe 7, and the grinding and screening work is performed according to the contents of the above embodiment, which will not be repeated here.

[0036] Under normal conditions, there is a relatively sufficient amount of grinding medium 14 between the dispersion plate 9 and the retaining plate 10. At this time, the grinding medium 14 is placed between the dispersion plate 9 and the retaining plate 10. Figure 5 As shown, when the grinding medium 14 exists between the dispersion plate 9 and the material blocking plate 10, the dispersion plate 9 will move relatively to the left and stretch the detection tension spring 902. Moreover, the dispersion plate 9 will synchronously drive the bead blocking ring sleeve 11 to move to the left through the reset spring 221, and use the bead blocking ring sleeve 11 to block the bead replenishing groove 133, so that the grinding medium 14 inside the driving cylinder 13 cannot be discharged from the bead replenishing groove 133.

[0037] Afterwards, the grinding media 14 in the driving cylinder 13 is transported by the auger 151 as described in the above embodiment, and finally discharged from the ball discharge groove 131, and the filtered ink raw materials are ground again. Since the air-avoiding ring groove 150 does not include the auger 151, a portion of the grinding media 14 will be relatively present at the location of the air-avoiding ring groove 150.

[0038] If during the working process, no grinding medium 14 passes between the dispersion disk 9 and the material blocking disk 10, it means that the amount of grinding medium 14 in this part is relatively insufficient, and this part needs to be supplemented to ensure that the ink raw materials flowing through this part are ground and refined. At this time, under the elastic force of the detection tension spring 902, the dispersion disk 9 pushes the gathering baffle 901 to approach the material blocking disk 10 until the gathering baffle 901 and the material blocking disk 10 are close to each other. Not only that, the bead blocking ring sleeve 11 is pushed to the right side synchronously under the elastic force of the reset spring 221. The bead blocking ring sleeve 11 moving to the right side will drive the guide rod 111 to pass over the reset push plate 20 and be placed at the bead supplement push plate 21, accompanied by the driven shaft 15 driving the reset push plate 20 and the bead supplement push plate 21 to rotate synchronously. When the bead supplement push plate 21 contacts the guide rod 111, the inclined surface of the bead supplement push plate 21 will cause the guide rod 111 to drive the bead blocking ring sleeve 11 to move further away from the dispersion disk 9, and the reset spring 221 is elastically stretched. During this process, the bead retaining ring 11 moving away from the dispersion disk 9 will cause the opening of the bead replenishing groove 133 to further increase, so that the grinding medium 14 retained in the air-avoiding ring groove 150 is largely discharged toward the dispersion disk 9, thereby ensuring the replenishment of the grinding medium 14 in this area.

[0039] As the drive cylinder 13 rotates continuously, the grinding medium 14 will also be as described in the first embodiment. Fig.14 The grinding medium 14 moves along the given path. When the grinding medium 14 moves between the dispersion plate 9 and the material retaining plate 10, it means that there is no need to replenish the grinding medium 14. After that, since the ball is placed between the dispersion plate 9 and the material retaining plate 10, the dispersion plate 9 moves to the left and the detection tension spring 902 is stretched. The bead retaining ring 11 is pulled by the reset spring 221 to move to the left synchronously, and there is a tendency to block the bead replenishing groove 133. Figure 5 As shown, if the grinding medium 14 blocks the guide rod 111 from resetting during the movement of the bead retaining ring 11 to the left, the dispersion disk 9 pulls the bead retaining ring 11 to the left, so that the bead retaining ring 11 always has a tendency to move to the left. When the bead retaining ring 11 moves to the position of the reset push plate 20, the reset push plate 20, which rotates with the driven shaft 15, pushes the guide rod 111 further toward the dispersion disk 9 through the inclined surface of the reset push plate 20, until the bead retaining ring 11 completely blocks the bead filling groove 133. Figure 5 It can also be seen that the bottom of the bead replenishing groove 133 is provided with an oblique angle, which can greatly reduce the possibility of the grinding medium 14 being stuck between the guide rod 111 and the bead replenishing groove 133.
