Description

Technical Field

[0001] The utility model relates to the technical field of paper printing, in particular to a printing machine with a paper alignment device. Background Art

[0002] Printing is the process of transferring ink from originals such as text, pictures, photos, anti-counterfeiting, etc. to the surface of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, inking, and pressurization. In the production process of paper, it is often necessary to print the paper. When printing the paper currently on the market, the paper to be printed is generally placed directly on a conveyor belt, and then conveyed by the conveyor belt to the printing area of ​​the printing equipment for printing.

[0003] For example, the publication number CN216763633U discloses a paper positioning device for printing production. When the conveyor belt is used to transport the paper, the inclined plate on the side of the conveyor belt can perform preliminary calibration on the position of the paper. After the preliminary calibration is completed, the paper is further calibrated through the correction plate. The inclined plate and the correction plate can correct the position of the paper during the paper transportation process.

[0004] However, the practicability of the alignment structure is poor when in use. The alignment plate and the inclined plate can only be driven by an electric telescopic rod to move together, and the inclination angle of the inclined plate cannot be adjusted in actual use, resulting in the inability to fit printing papers of different widths well, thereby reducing the practicability of the device. In view of this, we propose a printing press with a paper alignment device. Utility Model Content

[0014] Preferably, a handle is fixedly mounted on the upper end of the screw rod.

[0015] Compared with the prior art, the utility model provides a printing press with a paper alignment device, which has the following beneficial effects:

[0016] 1. The printing machine with a paper alignment device is provided with an adjustment structure so as to facilitate the adjustment of the inclination angles of the two sets of guide plates in actual use. The two sets of sliders are driven to move inside the slide groove by rotating the screw rod, and the moving rod and one end of the guide plate are driven to move by the slider. At this time, the other end of the guide plate is rotated by the rotating rod, so that the guide plate can fit the printing paper of different widths well, and the moving rod and the return spring are arranged on the side wall of the guide plate to prevent the corners of the printing paper from hard contact with the guide plate to cause damage, thereby improving the practicality of the device.

[0017] 2. The printing machine with a paper alignment device is provided with an anti-pressure structure so as to facilitate the correction of the corners of the printed paper. When the corners of the printed paper move on the side wall of the guide plate, they will be squeezed to a certain extent, so that the guide plate moves outward, and the guide plate moves through the moving rod and compresses the reset spring. At this time, the movement of the moving rod drives the Z-shaped rod to move in the opposite direction, and the movement of the Z-shaped rod drives the T-shaped rod and the push plate to move outward to correct the corners of the printed paper, thereby preventing the corners of the printed paper from always moving against the side wall of the guide plate and causing damage.

[0026] In one embodiment of the present invention, an adjustment structure 3 is provided to facilitate adjusting the inclination angle of the two groups of guide plates 36 in actual use, and a conveying structure 5 is provided to transport and move the printed paper. The conveying structure 5 is a combination of an existing simple conveyor belt, a rotating roller and a driving motor. This is an existing conventional technology and is not described in detail here. A U-shaped frame 31 and two groups of matching slide grooves 32 and sliders 37 are provided to facilitate the user to adjust the inclination angle of the two groups of guide plates 36 together, without the user having to adjust the angle separately, thereby improving the practicality of the device.

The upper end of the moving block 42 is hinged with one end of a push rod 43, and the other end of the push rod 43 is hinged with the side wall of the moving rod 311. The lower end of the moving block 42 is hinged with one end of a support rod 44, and the other end of the support rod 44 is hinged with the upper end of a Z-shaped rod 45. The lower end of the Z-shaped rod 45 passes through the side wall of the fixed box 39 and is fixedly installed with one end of a T-shaped rod 46. The other end of the T-shaped rod 46 passes through the side wall of the opening 41 and is fixedly installed with a push plate 47. The lower end of the fixed box 39 is provided with a bayonet adapted to the moving trajectory of the Z-shaped rod 45. By setting the anti-pressure structure 4, it is convenient to push the corners of the printed paper.

[0028] During operation, the printed paper is placed on the surface of the conveying structure 5 for transportation and movement. When the printed paper moves, it will complete the correction work by contacting with the guide plate 36. When adjusting the position of the two sets of guide plates 36, the user can rotate the handle 8 to drive the screw 33 to rotate. The rotation of the screw 33 drives the sleeve 34 on its surface to move up and down. The two-way movement of the sleeve 34 drives the connecting rod 38 of the side wall to move. The movement of the connecting rod 38 drives the two sets of sliders 37 hinged to it to move inside the slide groove 32. The slider 37 drives the fixed box 39 of the side wall to move. The movement of the fixed box 39 drives the moving rod 311 and one end of the guide plate 36 to move. At this time, the other end of the guide plate 36 is rotated by the rotating rod 35. , and when the corner of the printed paper is rigidly pressed against the surface of the guide plate 36, the guide plate 36 can be moved outward to a certain position to avoid direct friction damage to the corner of the printed paper. The guide plate 36 moves through the moving rod 311 and compresses the reset spring 312. At this time, the moving rod 311 moves to drive the push rod 43 on its side wall to move, and the push rod 43 moves to drive the moving block 42 hinged thereto to move downward. The moving block 42 moves downward to drive the support rod 44 on its side wall to move, and the support rod 44 moves to drive the Z-shaped rod 45 hinged thereto to move. The movement of the Z-shaped rod 45 drives the T-shaped rod 46 and the push plate 47 on its side wall to move outward to push the corner of the printed paper, thereby further improving the practicality of the device.
