Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a multifunctional printing device. Background Technology

[0002] Traditional printing equipment typically supports only a single printing process (such as flexographic or gravure). Switching processes requires replacing the entire machine or major components, resulting in high equipment costs, large footprint, and low switching efficiency. For example, flexographic printing presses rely on halftone rollers for ink transfer but struggle to achieve the high ink volume printing effects of gravure; gravure printing presses require a separate impression roller system, which is incompatible with the structure of flexographic equipment. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multifunctional printing equipment that can realize the conversion between flexographic printing and gravure printing, reduce equipment costs, and reduce the floor space required.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a multi-functional printing device, including a first multi-functional roller, a second multi-functional roller, and a pressing roller. The second multi-functional roller is located between the first multi-functional roller and the pressing roller. The first multi-functional roller includes a first mandrel, which cooperates with a screen roller sleeve to form a screen roller and a first plate roller sleeve to form a first plate roller. The second multi-functional roller includes a second mandrel, which cooperates with a second plate roller sleeve to form a second plate roller and a second printing roller sleeve to form a printing roller. The second mandrel cooperates with a printing roller sleeve to form a printing roller. The screen roller, the second plate roller, and the pressing roller are combined to form a flexographic printing unit, and the first plate roller, the printing roller, and the pressing roller are combined to form a gravure printing unit.

[0005] As an improvement, it also includes a first guide roller, a second guide roller, and a third guide roller. The first guide roller is located to the upper right of the second multi-functional roller, the second guide roller is located to the upper right of the pressed roller, and the third guide roller is located to the lower right of the pressed roller. In the flexographic printing unit, the film material passes through the first guide roller, the pressed roller, and the second guide roller in sequence. In the gravure printing unit, the film material passes through the first guide roller, the impression roller, the third guide roller, and the second guide roller in sequence.

[0006] The beneficial effects of this utility model compared with the prior art are:

[0007] The first and second multi-functional rollers in the printing press adopt a sleeve structure, with two sets of sleeves prepared respectively, one for flexographic printing and one for gravure printing. The mandrel size is made to be consistent for easy replacement. Attached Figure Description

[0008] Figure 1 This is a diagram showing the combined state of flexographic printing.

[0009] Figure 2 This is a diagram showing the combined state of gravure printing. Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] like Figure 1 , 2 As shown, a multifunctional printing device includes a first multifunctional roller 1, a second multifunctional roller 2, a pressing roller 3, and a guide roller assembly. The second multifunctional roller 2 is located between the first multifunctional roller 1 and the pressing roller 3. The first multifunctional roller 1 adopts a sleeve-type structure, including a first mandrel 11 and sleeve accessories. The sleeve accessories are either a screen printing roller sleeve 12 or a first printing roller sleeve 13. The first mandrel 11 and the screen printing roller sleeve 12 cooperate to form a screen printing roller, and the first mandrel 11 and the first printing roller sleeve 13 cooperate to form a first printing roller. The second multifunctional roller 2 adopts a sleeve-type structure, including a second mandrel 21 and sleeve accessories. The sleeve accessories are either a second printing roller sleeve 22 or an impression roller sleeve 23. The second mandrel 21 and the second printing roller sleeve 22 cooperate to form a second printing roller, and the second mandrel 21 and the impression roller sleeve 23 cooperate to form an impression roller. The screen printing roller, the second printing roller, and the pressed roller 3 combine to form a flexographic printing unit; the first printing roller, the impression roller, and the pressed roller 3 combine to form a gravure printing unit. When converting from flexographic printing to gravure printing, the flexographic screen printing roller must first be replaced with a gravure printing printing roller, then the flexographic printing roller must be replaced with a gravure printing impression roller, and finally the material feed path must be changed to suit gravure printing to complete the gravure printing process. The guide roller group includes a first guide roller 4, a second guide roller 5, and a third guide roller 6. The first guide roller 4 is located to the upper right of the second multi-functional roller 2, the second guide roller 5 is located to the upper right of the pressed roller 3, and the third guide roller 6 is located to the lower right of the pressed roller 3. In the flexographic printing unit, the film material passes sequentially through the first guide roller 4, the pressed roller 3, and the second guide roller 5; in the gravure printing unit, the film material passes sequentially through the first guide roller 4, the impression roller, the third guide roller 6, and the second guide roller 5.
