[0002] The paste-making device for printing paste production is an indispensable piece of equipment in the printing production process. This device is mainly used to mix and paste raw materials such as pigments, binders, and thickeners to form a paste suitable for printing. The paste-making device typically uses high-speed rotating blades to shear, impact, and grind the paste, refining the raw material particles and ensuring thorough mixing of various materials. This ensures the uniformity and stability of the paste, achieving an ideal paste state and thus improving printing quality. If the paste contains impurities or excessively large particles, it may cause blockage of the device, affecting production continuity. Utility Model Content

[0003] The purpose of this utility model is to provide a pulping device for printing paste production. By optimizing the design of the pulping and stirring mechanism, the pulping effect and stability of the pulping operation are improved, ensuring the overall dispersion uniformity and stability of the paste, and improving the printing quality of the printing paste.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0006] The pulping assembly includes a first rotating shaft and a plurality of pulping blades disposed on the first rotating shaft.

[0007] The dispersing component is located at the lower part of the pulping cylinder. The dispersing component includes a second rotating shaft arranged laterally inside the pulping cylinder. A plurality of dispersing plates are arranged on the second rotating shaft, and dispersing blades are arranged on the outer side of the dispersing plates along the length direction.

[0008] Furthermore, the plurality of pulping blades are evenly distributed circumferentially along the first rotating axis.

[0009] Furthermore, the pulping blade has an arc-shaped or semi-rectangular structure.

[0010] Furthermore, several transverse blades are also provided on the outer side of the pulping blade.

[0011] Furthermore, an annular cutting disc is provided at the bottom of the first rotating shaft, and multiple cutting teeth are provided on the outer circumferential surface of the annular cutting disc.

[0012] Furthermore, multiple cutting blades are provided on the outer circumference of the annular cutting disc, and the cutting blades and multiple cutting teeth are distributed at intervals.

[0013] Furthermore, the cutting blade is fishtail shaped.

[0016] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0017] In use, the raw materials are fed into the pulping cylinder through the feed inlet at the top. Simultaneously, the pulping assembly is activated, and a drive motor rotates the first rotating shaft, which in turn rotates multiple pulping blades. These blades shear, pulp, and mix the raw materials falling into the pulping cylinder. The raw materials continue to fall freely to the bottom of the cylinder. At this point, the rotation of the second rotating shaft drives multiple dispersing plates to rotate. During this rotation, the blades further shear, pulp, and mix the raw materials. More importantly, they more thoroughly agitate and disperse the pulp at the bottom of the cylinder, preventing prolonged sedimentation or stratification. This improves the pulping effect and stability of the pulping operation, ensuring the overall uniformity and stability of the pulp dispersion, and ultimately enhancing the printing quality of the printing paste.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Example 1

[0025] A pulping device for producing printing paste includes a pulping cylinder 1, wherein a pulping component and a dispersing component are respectively arranged from top to bottom inside the pulping cylinder 1.

[0026] The pulping assembly includes a first rotating shaft 3 and a plurality of pulping blades 4 disposed on the first rotating shaft 3.

[0027] The dispersing component is located at the lower part of the pulping cylinder 1. The dispersing component includes a second rotating shaft 10 arranged laterally inside the pulping cylinder 1. A plurality of dispersing plates 9 are arranged on the second rotating shaft 10. Dispersing blades 8 are arranged on the outer side of the dispersing plates 9 along the length direction. Both the first rotating shaft 3 and the second rotating shaft 10 are connected to a drive motor.

[0028] Working Principle: In use, the raw materials are fed into the pulping cylinder 1 through the feed inlet 2 at the top. Simultaneously, the pulping assembly is activated, and the drive motor rotates the first rotating shaft 3, which in turn rotates multiple pulping blades 4. The pulping blades 4 shear, pulp, and mix the raw materials falling into the pulping cylinder 1. The raw materials continue to fall freely to the bottom of the pulping cylinder 1. At this point, the rotation of the second rotating shaft 10 drives multiple dispersing plates 9 to rotate. During this rotation, not only are the pulping blades 8 further shearing, pulping, and mixing the raw materials, but more importantly, the pulp at the bottom of the pulping cylinder 1 is more thoroughly agitated and dispersed. This prevents most of the pulp from accumulating at the bottom for extended periods or causing stratification, and also avoids clogging that could affect production continuity. This improves the pulping effect and stability of the pulping operation, ensuring the overall uniformity and stability of the pulp dispersion, and ultimately improving the printing quality of the printing paste.

[0029] In this embodiment, the plurality of pulping blades 4 are evenly distributed along the circumference of the first rotating shaft 3, thereby improving the uniformity and efficiency of pulping.

[0030] In this embodiment, the pulping blade 4 has an arc-shaped or semi-rectangular structure and protrudes outward. For example, a pair of pulping blades 4 symmetrically arranged along the center of the first rotating axis 3 have a rectangular frame structure. The outwardly protruding pulping blades 4 can increase the contact area with the raw materials and ensure a more efficient pulping effect.

[0031] In this embodiment, several transverse blades 5 are also provided on the outer side of the pulping blade 4. In this way, during the rotation process, the transverse blades 5 can contact and shear the raw material in multiple directions, thereby improving pulping efficiency.

[0032] In this embodiment, an annular cutting disc 7 is provided at the bottom and / or top of the first rotating shaft 3. Multiple cutting teeth 71 are provided on the outer circumferential surface of the annular cutting disc 7. In this way, during the rotation of the first rotating shaft 3, the cutting teeth 71 can be used to further cut and pulp the raw material, so that the pulping of the raw material is more thorough.

[0033] In this embodiment, a plurality of cutting blades 6 are also provided on the outer circumferential surface of the annular cutting disc 7. The cutting blades 6 and the plurality of cutting teeth 71 are distributed at intervals. The dual action between the cutting blades 6 and the cutting teeth 71 is used to cut the falling raw material more quickly and efficiently, ensuring that the raw material can be fully sheared and pulped in different angles and directions during the falling process.

[0034] In this embodiment, the cutting blade 6 is fish-tail shaped, which increases the contact area with the raw material and ensures a more efficient pulping effect.

[0035] In this embodiment, the dispersing plate 9 is inclinedly arranged on the second rotating shaft 10, and multiple dispersing plates 9 are evenly distributed along the circumference of the second rotating shaft 10. In this way, during the rotation, the slurry can be stirred in a vortex shape, which can make the stirring effect of the slurry at the bottom more sufficient, thereby ensuring the dispersion effect of the slurry and the sufficient depth of pulping.

[0036] In this embodiment, the material-dispensing blade 8 is irregularly arc-shaped, which allows for a larger contact area with the raw material, resulting in deep dispersion and pulping.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
