Detailed Description of the Embodiment
[0044] The following will further describe the present application in detail in conjunction with the attached Figures 1-6 drawings.
[0045] An embodiment of the present application discloses an adjustable paper guide frame and a printing machine.
[0046] In a first aspect, an embodiment of the present application discloses an adjustable paper guide frame.
[0047] Referring to Figure 1 and Figure 2 , an adjustable paper guide frame includes two lateral brackets 1, two vertical mounting plates 3 and two horizontal mounting plates 4. The lateral brackets 1 are used for bolt connection with the printing machine body. An installation space is formed between the two lateral brackets 1, and a support roller 2 is rotatably connected between the two lateral brackets 1.
[0048] Referring to Figure 1 and Figure 2 , the vertical mounting plate 3 is fixedly welded to one end of the lateral bracket 1, and the vertical mounting plate 3 is vertically arranged. The end of the vertical mounting plate 3 away from the lateral bracket 1 is fixedly welded to the horizontal mounting plate 4, and the horizontal mounting plate 4 is horizontally arranged. In order to stably convey the paper output from the paper roll, the adjustable paper guide frame further includes a vertical adjusting roller 5 and a horizontal adjusting roller 7. Both ends of the vertical adjusting roller 5 are rotatably connected with mounting blocks 6, and the mounting blocks 6 are slidably connected with the vertical mounting plate 3, and the mounting plate slides along the vertical direction.
[0049] Referring to Figure 2 , both ends of the horizontal adjusting roller 7 are respectively rotatably connected with the two horizontal mounting plates 4, and the axial directions of the support roller 2, the vertical adjusting roller 5 and the horizontal adjusting roller 7 are the same. The horizontal adjusting roller 7 and the support rod are respectively located on the opposite sides of the vertical plane where the vertical adjusting roller 5 is located, forming an inclined conveying structure for the paper.
[0050] Referring to Figure 2 and Figure 3 , since the support roller 2, the vertical adjusting roller 5 and the horizontal adjusting roller 7 will vibrate when conveying the paper, and the vibration will affect the stable conveyance of the paper. In order to reduce the amplitude of the vibration, two anti-vibration plates 32 are vertically welded on the vertical mounting plate 3. The anti-vibration plates 32 are vertically arranged and perpendicular to the vertical mounting plate 3. In order to realize the sliding guidance of the mounting block 6 while anti-vibrating, the two anti-vibration plates 32 are respectively located on the opposite sides of the vertical mounting plate 3. The cross-sectional shapes of the vertical mounting plate 3 and the two anti-vibration plates 32 are "I"-shaped, and the mounting block 6 is slidably connected with the anti-vibration plate 32.
[0051] Referring to Figure 4 , in order to improve the structural strength between the vertical mounting plate 3 and the horizontal mounting plate 4, the adjustable paper guide frame further includes two diagonal bracing plates 9. One end of the diagonal bracing plate 9 is fixedly welded to one anti-vibration plate 32, and the other end of the diagonal bracing plate 9 is fixedly welded to the horizontal mounting plate 4, forming a triangular structure.
[0052] Reference Figure 5 , in order to quickly and intuitively know the height adjustment value of the vertical adjustment roller 5, at least one seismic plate 32 is connected with a scale 321 by screws. In this application, the number of scales 321 can be one, two, or three. In this embodiment, the number of scales 321 is one, and the scale direction of the scale 321 is vertically arranged.

[0054] Reference Figure 5 and Figure 6 , the fixing unit 8 includes a sliding frame 81, a locking column 82, and a force application bar 83. The sliding frame 81 is slidably connected to the vertical mounting plate 3 and the seismic plate 32, and the sliding frame 81 is welded and fixed to the side of the mounting block 6 away from the vertical mounting plate 3. Through the sliding frame 81, the mounting block 6 can be kept sliding in the sliding channel formed by the vertical mounting plate 3 and the seismic plate 32; the number of locking columns 82 is two. A plurality of locking holes 31 for the locking columns 82 to pass through are provided on the vertical mounting plate 3.

The force application bar 83 is located on the side of the vertical mounting plate 3 away from the vertical adjustment roller 5. Through the force application bar 83, it is convenient to simultaneously pull out the two locking columns 82; in order to facilitate controlling the height position of the mounting block 6 when adjusting the height of the vertical adjustment roller 5, a force application handle 811 is welded and fixed on the sliding frame 81.
[0056] The implementation principle of an adjustable paper guide frame in an embodiment of the present application is as follows: Fix the lateral bracket 1 to the printing press body with bolts. Then, according to the relative height difference between the paper feed port of the current printing press body and the paper roll, apply force to the sliding frame 81 through the force application handle 811. The connection between the sliding frame 81 and the mounting block 6 enables the mounting block 6 to slide within the sliding channel until the mounting block 6 slides into place. Apply force to the force application bar 83, and the force application bar 83 simultaneously drives two locking columns 82 to pass through the locking holes 31 and insert into the blind holes formed in the mounting block 6, realizing the position fixation of the mounting block 6. At this time, the relative positions of the vertical adjusting roller 5, the support roller 2, and the horizontal adjusting roller 7 are adjusted. The paper is output from the paper roll and sequentially passes through the horizontal adjusting roller 7, the vertical adjusting roller 5, and the support roller 2 and enters the printing press body for printing operations.
