Description

Technical Field

[0001] The invention relates to the technical field of color printing processing equipment, in particular to a manufacturing and processing device for a color printing packaging box. Background Art

[0002] Box packaging is very common in daily life. Different products are usually packaged in different boxes. For the sake of beauty and to show the products inside in the form of pictures, most boxes often need to be printed in color when producing them. At this time, a color printing machine is needed. A color-printed box is a box used to package products. Different colors are used on the same page for printing in batches to achieve a color picture effect. The original text, pictures, photos, etc. are processed through plate making, inking, pressurization and other processes to transfer the ink to the outside of the box to achieve the effect of packaging and conveying product information.

[0003] In the traditional production of color-printed packaging boxes, multiple steps are usually required to complete embossing, molding, printing and other tasks, and these steps often require manual intervention or frequent adjustment of mechanical equipment, resulting in long production cycles and low efficiency. The mold matching and embossing processes are often easily affected by human operation or equipment accuracy, resulting in uneven embossing effects and possible deviations in printed patterns, making it difficult to ensure the consistency of each packaging box. In the color printing process, especially when the use of printing liquid is involved, liquid leakage or air entry is likely to occur, affecting the quality of the printing liquid and even causing oxidation during the printing process, affecting the appearance and quality of the product. Especially in the embossing process, steps such as mold opening and closing, embossing and demolding may need to be manually operated separately, which not only reduces production efficiency but also easily leads to human errors. Long-term frequent operations will cause increased wear of traditional molds, especially in the embossing process. Frequent wear of the mold contact surface may affect the embossing effect and increase production costs. Summary of the Invention

[0015] The application provides a manufacturing and processing device for color printing packaging boxes. 1、The application has the effects of efficient filling and sealing system: the high-temperature preformed printing liquid is injected into the impression cavity through the filling pipe, and the continuous filling mode ensures uniform coverage of the printing liquid and avoids liquid splashing or unevenness. The filling pipe is sealed by the sealing pipe sleeve, which can effectively prevent liquid leakage and ensure the stability during the impression process.

The damping hydraulic part transmits power through the sliding block, ensuring that the upper mold cover and the lower mold cover can be smoothly closed and precisely docked.

The composite mold cover and the impression cavity work together to ensure the accurate reproduction of the printing pattern and the surface details of the box plate. This design makes the surface printing effect of the packaging box more delicate, improving the appearance quality of the product. The composite mold pressing mechanism can simultaneously perform surface detail impression during the impression process. The internal oxygen is discharged through the exhaust design to prevent oxidation, ensuring that the surface printing quality will not be affected by color difference or surface defects caused by oxidation.

[0018] 4、The present application has an automatic and efficient liquid discharge mechanism: after the impression is completed, the damping hydraulic part is started, the upper mold cover drives the center shaft to rotate clockwise, the linkage gear and the top rack are driven to cooperate with each other, the pinion and the rotating cylinder are driven to rotate in the opposite direction. This design makes the external threaded rod drive the ejection table to lift upward in the impression cavity two, effectively pushing out the residual molten liquid and the formed box plate, ensuring that the mold is completely cleaned after each operation, improving the production efficiency and product quality. Through the exhaust device, oxygen is discharged in time during the molding process, avoiding the oxidation reaction of the molten liquid due to excessive oxygen, further ensuring the delicacy of the printing details and the molding quality.

[0019] 5、The present application has a multifunctional mold design: the technical solution realizes the synchronous operation of printing and impression forming through the design of the composite mold cover, avoiding the complicated process of multiple processes in traditional production. Through the integrated mold design, not only the production efficiency is improved, but also the overall quality and delicacy of the molded parts are improved. The precise cooperation of the sliding block, the sliding carriage, the side rod and the stepped ramp realizes the vertical descent of the composite mold cover. The sliding adjustment of side rod one and side rod two inside the sliding carriage ensures that the composite mold cover can accurately descend and perform surface printing on the box plate, enhancing the detail die casting effect.
