Several arc-shaped stirring plates 5 are provided on the outer wall of the auxiliary stirring shafts 3, and the radius of curvature of the arc-shaped stirring plates 5 gradually increases from the inside to the outside, so that the material can be subjected to shear force during flow.

[0023] The drive assembly 15 includes a motor and a reducer. The motor is bolted to the top of the mixing cylinder 1, and its output shaft is connected to the input end of the reducer via a coupling. The output end of the reducer is fixedly connected to the top of the main stirring shaft 2 via a keyway. The reducer housing is welded to the top of the mixing cylinder 1 via a bracket to ensure transmission stability. The mixing cylinder 1 has a feed inlet 7 at the top and a discharge outlet 8 at the bottom. A filter screen is installed at the feed inlet 7, which is fixedly connected to the inner wall of the feed inlet 7 via clips to filter large particulate impurities. A regulating valve is installed at the discharge outlet 8, which is threaded to the outer wall of the discharge outlet 8 to control the material flow rate.

[0024] The mixing cylinder 1 has several guide plates 6 on its inner wall, which are evenly distributed along the axial direction of the mixing cylinder 1. The guide plates 6 have an arc-shaped cross-section, with the convex direction of the arc facing the central axis of the mixing cylinder 1. The surface of the guide plates 6 has several grooves, the depth of which gradually increases from top to bottom, thereby guiding the material to form a vortex and enhancing the mixing effect. The mixing cylinder 1 has a heating jacket 11 on its outer wall. A heating chamber is formed between the inner wall of the heating jacket 11 and the outer wall of the mixing cylinder 1. An electric heating tube 12 is installed in the heating chamber and is fixedly connected to the inner wall of the heating jacket 11 via a bracket. The heating jacket 11 has an insulation layer 13 on its outer wall, which is fixedly connected to the outer wall of the heating jacket 11 with an adhesive to reduce heat loss. The bottom of the mixing cylinder 1 is provided with a slag discharge port 14, which is located on one side of the discharge port 8. Its opening direction is inclined downward. A sealing cover is provided at the slag discharge port 14. The sealing cover is connected to the edge of the slag discharge port 14 by a hinge and is used to periodically clean the residue inside the mixing cylinder 1.

[0025] The material conveying mechanism includes a conveying pipe 9 and a pump body 10. One end of the conveying pipe 9 is connected to the discharge port 8 of the mixing cylinder 1, and the other end extends to the next process equipment. The pump body 10 is mounted on the conveying pipe 9 to provide power support. The conveying pipe 9 includes a first straight pipe section, a second bend pipe section, and a third straight pipe section. One end of the first straight pipe section is connected to the discharge port 8 of the mixing cylinder 1 via a flange, and the other end is connected to one end of the second bend pipe section via a threaded connection.

The pump body 10 is bolted and installed below the second bend pipe section, with its inlet connected to the second bend pipe section and its outlet connected to the third straight pipe section.

[0026] In practical applications, the processing of UV-protected white ink for cigarette packaging is as follows: First, the raw materials are fed into the mixing cylinder 1 through the feed inlet 7. The filter screen at the feed inlet 7 effectively filters out large particulate impurities, preventing them from entering the mixing cylinder 1 and affecting the mixing effect. The motor in the drive assembly 15 is started, and the motor drives the main stirring shaft 2 to rotate through the reducer. The spiral blades 4 on the main stirring shaft 2 compress and disperse the material in stages, while the arc-shaped stirring blades 5 on the auxiliary stirring shaft 3 apply shear force to the material, thereby achieving efficient mixing of the material. The guide plate 6 on the inner wall of the mixing cylinder 1 further guides the material to form a vortex, enhancing the interaction between the materials and avoiding the color and adhesion problems caused by insufficient mixing in traditional devices.

[0027] During the mixing process, the electric heating tube 12 inside the heating jacket 11 heats the material inside the mixing cylinder 1, keeping it within a suitable temperature range to ensure mixing effect and product quality. The insulation layer 13 effectively reduces heat loss and lowers energy consumption. After mixing is complete, the material flow rate is controlled by adjusting the regulating valve at the discharge port 8, and the material is transported to the next process equipment by the pump body 10 through the conveying pipe 9. The conveying pipe 9 adopts a segmented structure, which facilitates installation and maintenance. At the same time, the pump body 10 makes material conveying more efficient and reduces the complexity of manual operation.

[0028] To ensure the long-term stable operation of the device, a slag discharge port 14 is provided at the bottom of the mixing cylinder 1 for periodically cleaning the residue inside the mixing cylinder 1. The residue can be discharged by opening the sealing cover at the slag discharge port 14, thus preventing the residue from affecting subsequent processing. Furthermore, the mixing cylinder 1 has a reasonable structural design, with tight connections between all components, ensuring the operational stability and reliability of the entire device. Through the above design, this utility model solves the problems of uneven mixing, high energy consumption, and inconvenient maintenance in the prior art, and has high practicality and promotional value.

[0029] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0030] In the cigarette packaging printing process, UV environmentally friendly white ink needs to be processed efficiently to ensure that its color uniformity and adhesion meet the requirements of subsequent processes. The following is an explanation of the actual operation steps of this processing device and its corresponding technical principles.

[0031] First, the operator feeds the raw materials into the mixing cylinder 1 through the feed inlet 7. The filter screen at the feed inlet 7 effectively blocks large particles of impurities from entering the mixing cylinder 1, preventing these impurities from affecting the mixing effect. This design achieves preliminary purification of the raw materials through physical interception, providing a basic guarantee for the subsequent mixing process. Then, the motor in the drive assembly 15 is started, and the motor drives the main stirring shaft 2 to rotate through the reducer. The spiral blades 4 on the main stirring shaft 2 begin to compress and disperse the material in stages. As the pitch of the spiral blades 4 gradually decreases from top to bottom, the material is subjected to gradually increasing pressure as it moves axially along the mixing cylinder 1, thus being gradually refined and evenly distributed. This design achieves preliminary dispersion of the material through the action of mechanical force.

[0032] Meanwhile, the arc-shaped stirring blades 5 on the auxiliary stirring shaft 3 apply shear force to the material. The radius of curvature of the arc-shaped stirring blades 5 gradually increases from the inside to the outside, so that the material is not only subjected to radial shearing during flow, but also forms a local turbulence effect, further enhancing the mixing effect. This structural design makes full use of the principles of fluid mechanics, so that the material is subjected to complex force fields in different directions, thereby significantly improving the mixing uniformity. The guide plate 6 on the inner wall of the mixing cylinder 1 further guides the material to form vortices. The surface of the guide plate 6 is provided with several grooves, and the depth of the grooves gradually increases from top to bottom. This design changes the flow path of the material, so that it forms a multi-layer vortex structure in the mixing cylinder 1, enhancing the interaction between materials and avoiding the color and adhesion problems caused by insufficient mixing in traditional devices.

[0033] During the mixing process, the electric heating tubes 12 inside the heating jacket 11 heat the material inside the mixing cylinder 1. The electric heating tubes 12 transfer heat to the inner wall of the mixing cylinder 1 through heat conduction, and then the heat is evenly transferred to the material from the inner wall, keeping the material within a suitable temperature range. The insulation layer 13 reduces energy consumption by minimizing heat loss. This heating and insulation design ensures that the material is always at the optimal temperature during the mixing process, thereby improving mixing efficiency and product quality.

[0034] After mixing is complete, the material flow rate is controlled by adjusting the regulating valve at the discharge port 8. The regulating valve is tightly fitted to the discharge port 8 via a threaded connection, enabling precise control of the material flow rate. The material is then conveyed to the next process equipment via the conveying pipe 9 and the pump body 10. The conveying pipe 9 adopts a segmented structure, with the first straight pipe, the second bend, and the third straight pipe connected by flanges or threads, facilitating installation and maintenance. The pump body 10 utilizes fluid dynamics principles to generate a stable pressure differential, driving the material to be conveyed efficiently and reducing the complexity of manual operation.

[0035] To ensure long-term stable operation of the equipment, a slag discharge port 14 is provided at the bottom of the mixing cylinder 1. Residue inside the mixing cylinder 1 can be discharged periodically by opening the sealing cap at the slag discharge port 14. The opening of the slag discharge port 14 is inclined downwards to facilitate automatic discharge of residue under gravity. This design effectively prevents residue from contaminating subsequent processing or affecting the performance of the equipment.

[0036] In summary, this utility model achieves efficient processing of UV environmentally friendly white ink for cigarette packaging through the above steps and principles. The synergistic effect of the main stirring shaft 2 and the auxiliary stirring shaft 3, the vortex guiding function of the guide plate 6, and the temperature control design of the heating jacket 11 jointly solve the problems of uneven mixing, high energy consumption, and inconvenient maintenance in the prior art, and has high practicality and promotional value.
