Description

Technical Field

[0001] The utility model relates to the technical field of ink and paint preparation, in particular to a filter frame with a multi-layer filtering structure for ink and paint preparation. Background Technique

[0002] Ink and paint is a material widely used in many fields. It combines the characteristics of ink and paint and has unique properties and application values. Ink and paint mainly consists of solvents, resins, pigments, and additives, etc. It has a relatively high viscosity and is easy to dry. Ink is used in the printing field to present patterns, words, etc. on the printing substrate, while paint is a material that can be coated on the surface of an object to form a solid film with strong adhesion, certain strength, and continuity.

[0003] In the production and preparation process of ink and paint, ensuring the purity and uniformity of the product is crucial for the performance and quality of the final product. Since ink and paint is composed of a variety of components mixed together, including pigments, resins, solvents, and various additives, these components are extremely likely to generate particles, agglomerates, or tiny impurities during the mixing process. These impurities will not only affect the key properties of ink and paint such as fluidity, gloss, adhesion, and drying property, but may also have an adverse impact on subsequent processing processes such as printing and spraying, such as clogging nozzles, reducing production efficiency, or damaging equipment. Content of the Utility Model

[0004] The utility model discloses a filter frame with a multi-layer filtering structure for ink and paint preparation, aiming to solve the technical problem that ink and paint is composed of a variety of components mixed together, including pigments, resins, solvents, and various additives, and these components are extremely likely to generate particles, agglomerates, or tiny impurities during the mixing process. These impurities will not only affect the key properties of ink and paint such as fluidity, gloss, adhesion, and drying property, but may also have an adverse impact on subsequent processing processes such as printing and spraying, such as clogging nozzles, reducing production efficiency, or damaging equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A filter frame with a multi-layer filtering structure for ink and paint preparation, including a base, a material receiving barrel, and a cleaning barrel, further comprising:

[0007] A filtering mechanism, including two filtering cylinders connected up and down. The interiors of the two filtering cylinders are respectively provided with a coarse filter screen and a fine filter screen. An installation ring is arranged on the circumferential inner wall of the filtering cylinder. The top edges of the fine filter screen and the coarse filter screen are placed on the top of the installation ring. The two filtering cylinders are connected end to end, and the coarse filter screen is arranged above the fine filter screen.

[0008] In this solution, the ink coating first passes through a coarse filter screen and then through a fine filter screen. The ink coating flows downward step by step. Each layer of filtration intercepts and removes a part of impurities and particles. As the ink coating continuously flows, its purity gradually increases, preventing particles, lumps or tiny impurities generated during the raw material mixing process of the ink coating from affecting the key properties such as the fluidity, gloss, adhesion and drying property of the ink coating. It may also cause adverse effects on subsequent processing processes such as printing and spraying, such as clogging the nozzle, reducing production efficiency or damaging the equipment. Moreover, the multi-layer filtration structure can significantly improve the filtration efficiency and quickly remove impurities and particles in the ink coating.

[0009] In a preferred solution, a hydraulic telescopic rod is arranged at the top of the base. An installation frame is arranged at the top of the hydraulic telescopic rod. A turntable is rotatably connected to the bottom of the installation frame. A fixing rod is arranged at the bottom of the turntable. A motor is arranged inside the installation frame. The motor provides power for the rotation of the turntable. A second fixing block is arranged on the circumferential outer wall of the fixing rod. Positioning holes are opened at the tops of the first fixing block and the second fixing block. A positioning pin is inserted into the positioning holes.

[0010] Adopting the above solution, after a certain period of filtration, impurity particles gradually accumulate on the coarse filter screen and the fine filter screen, affecting the filtration speed of the ink coating. In order not to affect the filtration efficiency of the ink coating, after the machine stops, the turntable and the fixing rod are rotated to replace a set of spare filtration mechanisms, and continue to filter the ink coating. Then, the replaced filtration mechanism is cleaned and reserved for later use. This reduces the downtime for cleaning and replacement, makes equipment maintenance more convenient and fast, reduces the maintenance cost and downtime, and further improves the work efficiency.

[0011] As can be seen from the above, a filter frame with a multi-layer filtration structure for ink coating preparation includes a base, a material receiving barrel and a cleaning barrel, and further includes:

[0012] A filtration mechanism, including two filter cylinders connected up and down. Coarse filter screens and fine filter screens are respectively arranged inside the two filter cylinders. Installation rings are arranged on the circumferential inner walls of the filter cylinders. The top edges of the fine filter screens and the coarse filter screens are placed on the tops of the installation rings. The two filter cylinders are connected end to end. The coarse filter screen is arranged above the fine filter screen. A filter frame with a multi-layer filtration structure for ink coating preparation provided by the present utility model has the technical effect of filtering the ink coating in multiple layers, gradually increasing the purity, and preventing particles, lumps or tiny impurities generated during the raw material mixing process of the ink coating from affecting the key properties such as the fluidity, gloss, adhesion and drying property of the ink coating.

The two filtering cylinders 7 are connected end to end, and the coarse filter screen 14 is arranged above the fine filter screen 15.

[0022] Specifically, the two filtering cylinders 7 are connected up and down. The coarse filter screen 14 is placed inside the upper filtering cylinder 7, and the fine filter screen 15 is placed inside the lower filtering cylinder 7. After the ink coating is conveyed to the filtering mechanism, it first passes through the coarse filter screen 14 and then through the fine filter screen 15. The ink coating flows downward step by step. Each layer of filtration will intercept and remove a part of impurities and particles. As the ink coating continuously flows, its purity gradually increases.

[0023] Refer to Figure 2 , in a preferred embodiment, a top cover 6 is arranged on the top of the filtering cylinder 7. A connecting pipe 10 is arranged on the top of the top cover 6.

[0025] Refer to Figure 1 , Figure 2 and Figure 3 , in a preferred embodiment, a hydraulic telescopic rod 2 is arranged on the top of the base 3. An installation frame 1 is arranged on the top of the hydraulic telescopic rod 2. The bottom of the installation frame 1 is rotatably connected to a turntable 4.

Positioning holes are opened at the tops of the first fixing block 12 and the second fixing block 13, and positioning pins are inserted into the positioning holes.

[0026] Specifically, after a certain period of filtration, impurities and particles gradually accumulate on the coarse filter screen 14 and the fine filter screen 15, affecting the filtering speed of the ink coating. In order not to affect the filtering efficiency of the ink coating, after shutting down the machine, rotate the turntable 4 and the fixing rod 11, replace a set of spare filtering mechanisms, continue to filter the ink coating, and clean the replaced filtering mechanism for standby.

[0027] Working principle: When in use, the two filter cartridges 7 are connected up and down. The coarse filter screen 14 is placed in the upper filter cartridge 7, and the fine filter screen 15 is placed in the lower filter cartridge 7. After the ink coating is transported to the filtering mechanism, it first passes through the coarse filter screen 14 and then through the fine filter screen 15. The ink coating flows downward step by step. Each layer of filtration will intercept and remove a part of impurities and particles. As the ink coating continuously flows, its purity gradually increases. After a certain period of filtration, impurity particles gradually accumulate on the coarse filter screen 14 and the fine filter screen 15, affecting the filtration speed of the ink coating. In order not to affect the filtration efficiency of the ink coating, after the machine is stopped, rotate the turntable 4 and the fixed rod 11 to replace a set of spare filtering mechanisms, continue to filter the ink coating, and clean the replaced filtering mechanism for standby.
