Description

Technical Field

[0001] This utility model relates to an improvement invention in the field of printing, and more particularly to an improvement invention of a combined paper feeding printing system. Background Technology

[0002] Digital printing presses are used for corrugated paper and ultra-thin tissue paper and linerboard, employing two completely different paper feeding mechanisms. Corrugated paper typically uses leading-edge feeding or belt feeding, relying on friction to transport the paper and prevent surface scratches. Tissue paper and linerboard use feeder heads, utilizing vacuum nozzles to gently separate the thin paper. Because their structures are entirely different, digital printing presses generally only have one type of paper feeding mechanism, depending on the requirements. Therefore, companies need to configure two independent printing systems, resulting in double the equipment investment and increased floor space requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a combined paper feeding and printing system.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the combined paper feeding and printing system includes a digital printing machine, characterized in that: the digital printing machine can be moved left and right on the ground track, and the front of the digital printing machine is equipped with a belt paper feeding mechanism and a feeder head paper feeding mechanism distributed left and right. The digital printing machine can move left and right to switch to the rear of the corresponding paper feeding mechanism according to the paper type required.

[0005] The belt paper feeding mechanism and the feeder head paper feeding mechanism are mounted on the same base and are adjacent to each other. The paper outlets are flush with each other and match the paper inlet of the digital printing machine.

[0006] The digital printing machine has a gear at the bottom and a rack on the corresponding side of the ground rail. The gear meshes with the rack and is equipped with a drive structure.

[0007] The drive structure includes a sprocket that is coaxially linked with the gear, and the sprocket is connected to the servo motor via chain drive.

[0008] The left and right ends of the ground track are equipped with digital printing machine movement limit structures.

[0009] The digital printing machine is equipped with a material receiving hopper at the rear.

[0010] The beneficial effects of this utility model are that the improved combined paper feeding and printing system adopts a belt-driven paper feeding mechanism and a feeder-driven paper feeding mechanism in parallel, with the digital printing press placed on a ground track and capable of movement. Depending on the type of paper used, the digital printing press moves to the rear of the corresponding paper feeding mechanism. This structure is compatible with multiple paper feeding mechanisms, reducing equipment redundancy, lowering energy consumption and space occupation, and reducing machine costs.

[0015] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-3 This combined paper feeding and printing system includes a digital printing machine 1, which is movable left and right on a ground rail 2. A belt paper feeding mechanism 3 and a feeder paper feeding mechanism 4 are arranged in front of the digital printing machine 1. The digital printing machine 1 can move left and right to switch to the rear of the corresponding paper feeding mechanism according to the paper type. The belt paper feeding mechanism 3 and the feeder paper feeding mechanism 4 are arranged on the same base and are adjacent to each other. The paper outlets are flush and match the paper inlet of the digital printing machine 1 to facilitate smooth paper feeding.

[0016] The working principle of this invention is as follows: Taking corrugated paper as an example, the digital printing press 1 is moved behind the belt-fed paper feeding mechanism 3 and connected to it. The corrugated paper is fed into the digital printing press 1 by the belt-fed paper feeding mechanism 3 for printing, and then sent out for collection after completion. Similarly, a feeder head paper feeding mechanism 4 is used to convey cotton paper and face paper.

[0017] As a further improved implementation, the digital printing machine 1 has a gear 5 at its bottom and a rack 6 on the corresponding side of the ground rail 2. The gear 5 meshes with the rack 6, and the gear 5 is equipped with a drive structure. Preferably, the drive structure includes a sprocket 7 coaxially linked with the gear 5. The sprocket 7 is connected to a servo motor via a chain 8. During operation, the servo motor drives the chain 8 and sprocket 7, causing the gear 5 to move on the rack 6, thereby propelling the digital printing machine 1 along the ground rail 2. The moving distance can be set via a program to ensure precise positioning.

[0018] As a further improved implementation, the left and right ends of the ground track 2 are provided with a digital printing machine 1 movement limiting structure 9 to restrict the digital printing machine 1 from leaving the ground track 2.

[0019] As a further improvement, the digital printing machine 1 is equipped with a material receiving hopper 10 at the rear to receive the printed products.

[0020] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
