Description

Technical Field

[0001] The present invention relates to the field of grinding equipment, and particularly to a bead mill applied to the production of vegetable oil-based offset printing ink. Background Art

[0002] Vegetable oil-based offset printing ink is made mainly from vegetable oil. Compared with traditional petroleum-based ink, it has the advantages of being renewable, having good environmental protection and low pollution, conforming to the development trend of green printing, and being widely used in fields such as packaging printing and publication printing. During its production process, various raw materials need to be mixed and then ground into a uniform and delicate ink product. The bead mill, through the high-speed rotating grinding disc and grinding beads inside, strongly squeezes, shears, and rubs the ink raw materials, can effectively refine the raw material particles, improve the dispersibility, stability, and uniformity of the ink, improve the fluidity and printing suitability of the ink, thereby ensuring good transfer and adhesion of the ink during the offset printing process, and enhancing the printing quality. Therefore, it has become an indispensable key equipment in the production of vegetable oil-based offset printing ink.

[0003] Most traditional bead mills for the production of vegetable oil-based offset printing ink drive the grinding disc to rotate for grinding work by a single transmission method. Usually, the grinding disc is directly driven by a motor or transmitted through a few gears. During actual work, after the raw materials enter the grinding chamber, although the grinding disc can grind the raw materials, due to the single transmission method, the grinding disc can only process the raw materials from a limited angle and method, and it is difficult to achieve all-round and multi-dimensional grinding. This results in insufficient refinement of the ink raw material particles, poor fineness and uniformity of the ink, and further affects the transfer performance and adhesion performance of the ink during the printing process, making it easy for printing products to have problems such as color difference and uneven ink layer. Therefore, in view of the above problems, a bead mill applied to the production of vegetable oil-based offset printing ink is proposed to solve the above problems. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] Refer to Figure 1 And Figure 2 As shown in [drawings], an embodiment provided by the present invention: A bead mill applied to the production of vegetable oil-based offset printing ink, including a base 1. The base 1 serves as the basic support structure of the entire bead mill, providing a stable installation foundation for other components such as the grinding barrel 2, ensuring the overall stability of the bead mill during operation, withstanding various forces during the operation of the equipment, and preventing the equipment from shaking or displacing. A grinding barrel 2 is fixedly connected to its top. The grinding barrel 2 is the main place for ink grinding work, providing a closed space for raw material grinding, accommodating transmission components such as the driving gear column 4, the driven gear I 14, the driven gear II 15, and the connecting tooth sleeve ring 13, as well as grinding components such as the grinding disc 18, so that the grinding process proceeds orderly inside it.

[0029] Refer to Figure 3 And Figure 5, an electric motor 3 is fixedly connected to the outside of the grinding barrel 2. The electric motor 3 serves as a power source to provide power for the operation of the bead mill. It drives the rotation of the driving gear column 4 through the driving end, thereby making the entire transmission system and grinding system operate. It is the power core of the equipment operation. The driving end of the electric motor 3 is fixedly connected to the driving gear column 4. The driving gear column 4 receives the power transmitted by the electric motor 3. On the one hand, through the meshing transmission with the driven gear one 14 and the driven gear two 15, the power is transmitted to other transmission components to achieve the coordinated rotation of multiple components; on the other hand, its rotation drives the threaded rod 6 fixedly connected thereto to rotate, providing power input for the movement of subsequent components.

[0030] The other end of the driving gear column 4 is fixedly connected to a threaded rod 6. Through its own rotation, the threaded rod 6 performs threaded transmission with the inner sleeve rod 5 and the threaded sleeve rod 7, converting the rotational motion transmitted by the driving gear column 4 into linear motion or relative motion between components, providing power and motion guidance for the movement of components such as the outer sleeve rod one 8, the outer sleeve rod two 10, and the outer sleeve rod three 12. The outer thread of the threaded rod 6 is connected to the inner sleeve rod 5. The inner sleeve rod 5 is threadedly connected to the threaded rod 6. When the threaded rod 6 rotates, it can move along the axis direction of the threaded rod 6 or generate relative rotation, participate in the movement of the entire transmission system, assist in realizing the transmission of power and the conversion of motion forms, and play a certain role in the stability and accuracy of the overall transmission.

[0031] The outer thread of the threaded rod 6 is connected to a threaded sleeve rod 7. The threaded sleeve rod 7 is threadedly connected to the threaded rod 6. When the threaded rod 6 rotates, it will rotate itself and may be accompanied by a certain axial movement. Its rotation drives the outer sleeve rod one 8 threadedly connected thereto to rotate. It is one of the key links in the transmission system for power transmission and motion conversion. The outer thread of the threaded sleeve rod 7 is connected to the outer sleeve rod one 8. A chute one 9 is opened on the outside of the outer sleeve rod one 8. It rotates under the drive of the threaded sleeve rod 7 and at the same time provides a sliding track for the outer sleeve rod two 10, enabling the outer sleeve rod two 10 to slide along the inner wall of the chute one 9 while rotating itself, realizing the further transmission of power and the change of motion forms.

[0032] Refer to Figure 6 And Figure 7 , the outer sleeve rod two 10 is slidably connected to the outside of the outer sleeve rod one 8. The inside of the outer sleeve rod two 10 is slidably connected to the inner wall of the chute one 9. It can slide along the chute one 9 while rotating with the outer sleeve rod one 8. A chute two 11 is opened on its outside, providing a sliding track for the outer sleeve rod three 12, further transmitting power and realizing the conversion of motion forms. The outer sleeve rod three 12 is slidably connected to the outside of the outer sleeve rod two 10. The outer sleeve rod three 12, as one of the end components of the transmission system, receives the power from the outer sleeve rod two 10, rotates itself and provides an installation base for the grinding disc 18, driving the grinding disc 18 to rotate to achieve the grinding of the ink raw materials and ensuring the stability of the installation and operation of the grinding disc 18.

[0033] There is a transmission component arranged outside the driving gear column 4. The transmission component includes a connecting tooth sleeve ring 13. The inside of the connecting tooth sleeve ring 13 is rotatably connected to the grinding barrel 2. Through meshing with the first driven gear 14 and the second driven gear 15, it participates in the power transmission of the transmission system, realizes the power distribution and coordinated rotation between different components, makes the movement of the entire transmission system more stable and efficient. The inside of the connecting tooth sleeve ring 13 is rotatably connected to the inside of the grinding barrel 2. A first driven gear 14 is rotatably connected inside the grinding barrel 2. The first driven gear 14 meshes with the external teeth of the driving gear column 4, receives the power transmitted by the driving gear column 4 and rotates.

[0034] At the same time, it meshes with the internal teeth of the connecting tooth sleeve ring 13 and transmits the power to the connecting tooth sleeve ring 13. It is an important component for power transmission and distribution in the transmission system, and assists in realizing the synchronous operation of multiple components. The external teeth of the first driven gear 14 are meshed with the external teeth of the driving gear column 4, and the external teeth of the first driven gear 14 are meshed with the internal teeth of the connecting tooth sleeve ring 13. A second driven gear 15 is rotatably connected inside the grinding barrel 2. The second driven gear 15 meshes with the external teeth of the driving gear column 4, receives the power transmitted by the driving gear column 4 and rotates. At the same time, it meshes with the internal teeth of the connecting tooth sleeve ring 13 and transmits the power to the connecting tooth sleeve ring 13. Acting together with the first driven gear 14, it makes the power distribution of the transmission system more uniform and the movement more stable.

[0035] The external teeth of the second driven gear 15 are meshed with the external teeth of the driving gear column 4, and the external teeth of the second driven gear 15 are meshed with the internal teeth of the connecting tooth sleeve ring 13. A plurality of first chutes 9 are provided on the outside of the outer sleeve rod 8. The first chutes 9 are provided on the outside of the outer sleeve rod 8, providing guidance and restraint for the sliding of the outer sleeve rod 10, so that the outer sleeve rod 10 can slide along a specified path while rotating with the outer sleeve rod 8, ensuring the accuracy and stability of the transmission, and assisting in realizing the hierarchical transmission of power.

[0036] The inside of the outer sleeve rod 10 is slidably connected to the inner wall of the first chute 9. A plurality of second chutes 11 are provided on the outside of the outer sleeve rod 10. The second chutes 11 are provided on the outside of the outer sleeve rod 10, providing guidance and restraint for the sliding of the outer sleeve rod 12, so that the outer sleeve rod 12 can slide along a specified path while rotating with the outer sleeve rod 10, ensuring the accuracy and stability of the transmission, and assisting in realizing the precise transmission of power to the outer sleeve rod 12. The inside of the outer sleeve rod 12 is slidably connected to the inner wall of the second chute 11.

[0037] Refer to Figures 8 to 9, multiple grinding disks 18 are detachably connected to the outside of the outer sleeve rod three 12. The grinding disks 18 are detachably connected to the outside of the outer sleeve rod three 12 and rotate with the outer sleeve rod three 12. Their surfaces come into contact with the ink raw materials and perform grinding operations such as extrusion, shearing, and friction on the raw materials through their own rotation. They are the direct working components for realizing the grinding and refinement of the ink raw materials. A limiting component is arranged on the outside of the outer sleeve rod three 12. The limiting component includes multiple positioning seats 16. The positioning seats 16 are fixedly connected to the outside of the outer sleeve rod three 12, providing positioning and support for the installation of the mounting seat 17. Through the cooperation with the mounting seat 17 and the locking nut 25, the stable installation of the mounting seat 17 is realized, and thus a foundation for the stable installation of the grinding disk 18 is provided.

[0038] The outside of the positioning seat 16 is fixedly connected to the outside of the outer sleeve rod three 12. Multiple mounting seats 17 are detachably connected to the outside of the outer sleeve rod three 12. The mounting seats 17 are detachably connected to the outer sleeve rod three 12, and cavities 19 are opened inside for installing limiting components such as the telescopic column 20. Through the cooperation with the positioning seat 16 and the locking nut 25, the grinding disk 18 is stably installed on the outer sleeve rod three 12, and at the same time, a mounting carrier is provided for the limiting component. Multiple cavities 19 are opened inside the mounting seat 17. The cavities 19 are opened inside the mounting seat 17, providing installation spaces for limiting components such as the telescopic column 20, the limiting plate 21, and the spring 22, enabling these components to be arranged orderly and work together.

[0039] The limiting function of the grinding disk 18 is realized. The telescopic column 20 is fixedly connected to the inside of the cavity 19. The telescopic column 20 is fixedly connected to the inside of the cavity 19, providing support and guidance for the limiting plate 21. During the installation and working process of the grinding disk 18, it ensures that the limiting plate 21 can move smoothly along the axis direction of the telescopic column 20, and cooperates with components such as the spring 22 to realize the limiting and buffering of the grinding disk 18. The top of the telescopic column 20 is fixedly connected to the limiting plate 21. The top of the limiting plate 21 is fixedly connected to the telescopic column 20, and the other side is fixedly connected to the limiting column 23. Under the action of the spring 22, it can move along the telescopic column 20. By driving the limiting column 23 to engage or disengage with the limiting groove 24 of the grinding disk 18, the limiting and loosening operations of the grinding disk 18 are realized, ensuring the stability of the installation and working of the grinding disk 18. The other side of the limiting plate 21 is fixedly connected to the limiting column 23. Multiple limiting grooves 24 are opened inside the grinding disk 18. The limiting grooves 24 are opened inside the grinding disk 18, cooperating with the limiting column 23 to provide a engaging position for the limiting column 23.

[0040] Through the interaction with the limit post 23, the positioning and limiting of the grinding disc 18 are realized, ensuring the position accuracy of the grinding disc 18 during operation. A spring 22 is sleeved outside the limit plate 21. The spring 22 is sleeved outside the limit plate 21, with one end fixed to the inner wall of the cavity 19 and the other end fixed to the limit plate 21. It generates an elastic force through its own elastic deformation, providing a reset force for the limit plate 21 and the limit post 23, enabling the limit post 23 to tightly engage in the limit groove 24 of the grinding disc 18, enhancing the limiting effect, and playing a buffering role during the installation and disassembly of the grinding disc 18. One end of the spring 22 is fixedly connected to the inner wall of the cavity 19, and the other end of the spring 22 is fixedly connected to the side of the limit plate 21 close to the telescopic column 20. The outer part of the limit post 23 is engaged with the inner wall of the limit groove 24.

[0041] A plurality of locking nuts 25 are threadedly connected inside the mounting seat 17. The locking nuts 25 are threadedly connected inside the mounting seat 17 and inside the positioning seat 16. Through tightening or loosening operations, the fastening or disassembly of the mounting seat 17 and the positioning seat 16 is achieved, thereby fixing or loosening the grinding disc 18, facilitating the installation, disassembly, and replacement of the grinding disc 18, and ensuring the stability of the grinding disc 18 during operation. The outer part of the locking nut 25 is threadedly connected to the inside of the positioning seat 16.

[0042] The top of the base 1 is fixedly connected with a feed inlet 26. The feed inlet 26 is fixedly connected to the top of the base 1 and is the inlet for the ink raw material to enter the bead mill, providing an inlet channel for the raw material and facilitating the operator to add the raw material to be ground into the equipment. Its structural design enables the raw material to flow smoothly into the diversion bin 27. The bottom of the feed inlet 26 is fixedly connected with the diversion bin 27. The bottom of the diversion bin 27 is fixedly connected to the feed inlet 26, and the output end is fixedly connected to the inside of the grinding barrel 2, guiding the raw material entering from the feed inlet 26, enabling the raw material to enter the inside of the grinding barrel 2 evenly and smoothly, avoiding the accumulation or spilling of the raw material, and providing guarantee for the smooth progress of the grinding work. The output end of the diversion bin 27 is fixedly connected to the inside of the grinding barrel 2.

[0043] Working principle: First, pour the vegetable oil-based offset printing ink raw material to be ground through the feed inlet 26. The diversion bin 27 connected to the bottom of the feed inlet 26 will smoothly guide the raw material into the inside of the grinding barrel 2. Start the motor 3, and the driving end of the motor 3 drives the driving gear column 4 to start rotating. When the driving gear column 4 rotates, the threaded rod 6 fixedly connected to it rotates synchronously. The inner sleeve rod 5 and the threaded sleeve rod 7 threadedly connected to the outside of the threaded rod 6 will generate corresponding movements due to the rotation of the threaded rod 6. When the threaded sleeve rod 7 rotates, it drives the outer sleeve rod one 8 to rotate. Since a chute one 9 is provided on the outside of the outer sleeve rod one 8, while the outer sleeve rod two 10 slides on the inner wall of the chute one 9, it will also rotate with the rotation of the outer sleeve rod one 8. Similarly, the chute two 11 on the outside of the outer sleeve rod two 10 enables the outer sleeve rod three 12 to slide on its inner wall and rotate accordingly.

[0044] Secondly, when the outer sleeve rod three 12 rotates, it rotates synchronously with multiple grinding discs 18 outside it. During the rotation of the grinding discs 18, in cooperation with the internal grinding medium, the vegetable oil-based offset printing ink raw materials entering the grinding barrel 2 are ground. During this process, under the action of the grinding discs 18, the raw materials are continuously squeezed, sheared, and rubbed, thereby achieving grinding effects such as particle refinement. During the rotation and grinding process of the grinding discs 18, the limiting component plays a role in stabilizing and positioning the grinding discs 18. In the internal cavity 19 of the mounting seat 17, the limiting plate 21 connected to the top of the telescopic column 20, and the limiting column 23 connected to the other side of the limiting plate 21, under the action of the spring 22, the limiting column 23 is always engaged with the limiting groove 24 inside the grinding disc 18, preventing the grinding disc 18 from axially moving or shifting in position during rotation, ensuring that the grinding disc 18 performs the grinding work stably and accurately. During the continuous operation of the motor 3, the above work process is continuously repeated, and the raw materials are continuously ground by the grinding discs 18 in the grinding barrel 2, and then the materials are discharged through the discharge port at the bottom of the grinding barrel 2.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
