Description

Technical Field

[0001] This invention belongs to the field of intelligent printing equipment technology, and in particular relates to a paper feeding device for a rotary digital printing press. Background Technology

[0002] Currently, the traditional printing industry is developing rapidly, and the technologies and auxiliary products involved are constantly being innovated. Increasingly complex rotary digital printing presses are gradually becoming more popular printing equipment. In daily use, rotary digital printing presses are usually operated manually by feeding paper. Due to the small internal space of rotary digital printing presses and the complexity of paper feeding, manual paper feeding is inefficient and prone to errors, resulting in printing errors and paper breakage. Automatic paper feeding equipment is safer, and researching automatic paper feeding equipment is imperative. Summary of the Invention

[0003] The purpose of this invention is to provide a paper feeding device for a rotary digital printing press. By setting up an automatic paper feeding device, the invention solves the problem that the existing rotary digital printing press paper feeding devices are inefficient and prone to errors, resulting in paper breakage and printing errors, when using manual paper feeding.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a paper feeding device for a rotary digital printing press, comprising a paper guide frame disposed around the periphery of the printing press, paper guide rollers disposed crosswise on the inner side wall of the paper guide frame, and a paper feeding device.

[0006] The paper feeding device includes a ground rail set on the side wall of the printing paper guide frame. Robot No. 1 and Robot No. 2 are slidably connected to the top of the ground rail. Robot No. 1 and Robot No. 2 can slide horizontally on the ground rail. The output ends of Robot No. 1 and Robot No. 2 are equipped with pneumatic fingers. The pneumatic fingers adjust the finger spacing by supplying air pressure to grip the printing paper to be fed, and alternately feed the printing paper into the printing paper guide roller.

[0007] Furthermore, the ground rail is composed of at least two slide rails connected end to end. Several equidistant positioning elements are welded to the side walls of the slide rails. The positioning elements have through holes in the middle for fixing the slide rails. In use, positioning bolts can be inserted into the positioning holes in the side walls of the positioning elements to fix the positioning elements and ensure the stability of the entire ground rail.

[0008] Furthermore, a dust-shielding component that can extend and retract along the length of the ground rail is fixedly connected to the top of the slide rail. By setting the dust-shielding component, the ground rail can be shielded, which can reduce dust falling on the ground rail, form an effective protection for the ground rail, and improve the safety of the ground rail.

[0009] Furthermore, the dust-shielding component has a corrugated structure as a whole, and the dust-shielding component is made of plastic or rubber. The advantage of adopting a corrugated structure for the dust-shielding component is that it can be stacked along the fold seam, so that it can move with Robot No. 1 and Robot No. 2 to achieve a further covering effect.

[0010] Furthermore, both Robot No. 1 and Robot No. 2 are provided with walking components on their side walls for driving them to slide horizontally on the ground track. The walking components drive Robot No. 1 and Robot No. 2, enabling them to slide horizontally on the ground track.

[0011] Furthermore, the walking component includes a drive motor fixedly connected to the side walls of Robot No. 1 and Robot No. 2, a drive gear fixedly connected to the output end of the drive motor, and a toothed plate fixedly connected to the top of the ground rail. The drive gears mesh with the toothed plates. When the drive motors on the side walls of Robot No. 1 and Robot No. 2 are working, they can drive the drive gears to mesh with the toothed plates to move in position, thereby realizing the automatic sliding of Robot No. 1 and Robot No. 2.

[0012] The present invention has the following beneficial effects:

[0013] Through the setup of a ground track, Robot 1, Robot 2, pneumatic fingers, dust-shielding components, and a walking component, the walking component can control Robot 1 and Robot 2 to slide on the ground track and use the pneumatic fingers to grip and transport paper. When Robot 1 and Robot 2 are moving, the program can control Robot 2 to grip the paper and first pass it through a transfer roller. Robot 1 will then follow and grip the paper-passing position of Robot 2. Robot 2 will continue to pass the paper, with Robot 1 assisting Robot 2 in passing the paper, simulating manual paper passing. This process is repeated to complete the entire paper-passing action. In addition, the dust-shielding components can be extended and retracted synchronously during walking, forming an effective protection for the ground track and improving the overall service life.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention is a paper feeding device for a rotary digital printing press, including a paper guide frame 1 disposed around the printing press, paper guide rollers 2 disposed crosswise on the inner side wall of the paper guide frame 1, and a paper feeding device 3.

[0028] The paper feeding device 3 includes a ground rail 31 set on the side wall of the printing paper guide frame 1. Robot No. 1 32 and Robot No. 2 33 are slidably connected to the top of the ground rail 31. Robot No. 1 32 and Robot No. 2 33 can slide horizontally on the ground rail 31. The output ends of Robot No. 1 32 and Robot No. 2 33 are equipped with pneumatic fingers 34. The pneumatic fingers 34 adjust the finger spacing by supplying air pressure to clamp the printing paper to be fed, and alternately feed the printing paper into the printing paper guide roller 2.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the ground rail 31 is composed of at least two slide rails 311 connected end to end. Several equidistant positioning parts 312 are welded to the side wall of the slide rail 311. The center of the positioning part 312 is provided with a through hole for fixing the slide rail 311. In use, the positioning bolt can be inserted into the positioning hole on the side wall of the positioning part 312 to fix the positioning part 312 and ensure the stability of the entire ground rail 31.

[0030] like Figure 1 , Figure 2 ,and Figure 5 As shown, a dust-shielding component 35 that can extend and retract along the length of the ground rail 31 is also fixedly connected to the top of the slide rail 311. By setting the dust-shielding component 35, the ground rail 31 can be shielded, which can reduce the amount of dust falling on the ground rail 31, form an effective protection for the ground rail 31, and improve the safety of the ground rail 31.

[0031] The dust-covering component 35 has a corrugated structure and is made of plastic or rubber. The advantage of the corrugated structure of the dust-covering component 35 is that it can be stacked along the fold seam, so that it can move with Robot No. 1 32 and Robot No. 2 33 to achieve a further covering effect.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, both Robot No. 1 32 and Robot No. 2 33 are provided with walking components 36 on their side walls for driving them to slide horizontally on the ground rail 31.

The drive gear 362 meshes with the toothed plate 37. When the drive motor 361 on the side wall of robot 1 32 and robot 2 33 is working, it can drive the drive gear 362 to mesh with the toothed plate 37 to move the position, thereby realizing the automatic sliding of robot 1 32 and robot 2 33.

[0034] Specifically, during operation / use of the paper feeding device of this rotary digital printing press: the walking component 36 can control the sliding of robot 1 32 and robot 2 33 on the ground rail 31. Specifically, the drive motor 361 on the side wall of robot 1 32 and robot 2 33 can drive the drive gear 362 to mesh with the toothed plate 37 to move the position, thereby realizing the automatic sliding of robot 1 32 and robot 2 33. The pneumatic finger 34 is controlled by the program to open and close to hold the paper for conveying. Specifically, robot 2 33 clamps the paper and first passes it through a transfer roller. Robot 1 32 follows closely behind and clamps the paper feeding position of robot 2 33. Robot 2 33 continues to feed the paper. Robot 2 33 feeds the paper, and robot 1 32 assists, simulating manual paper feeding, and so on, to complete the entire paper feeding action.
