Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a paper conveying device of a printing press with an anti-deviating function. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its operating principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied manually or by the printing press to the areas of the plate where the text and image appear. The ink is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), producing a printed product identical to the printing plate.

[0003] Printing machines are generally equipped with conveyors that transport the paper placed on them into the printing machine. However, when the paper placed on the conveyor belt enters the printing machine body, it is not well aligned. When the paper enters the printing machine crookedly, the printed product will also be crooked. Summary of the Invention

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a printing press paper conveying device with anti-deviation function, including a conveyor belt 1, a printing device 8 and printing paper 4, the outer ring surface of the conveyor belt 1 is recessed to form a conveying trough 2 with an annular structure, and a plurality of annular strips 3 for adjusting the width of the conveying trough 2 are arranged on both sides of the conveyor trough 2, and a plurality of connecting parts for fixing the annular strips 3 are installed on the conveyor belt 1, and driven rollers 10 and active rollers are arranged at both ends of the conveyor belt 1. A frame 5 is installed on both sides of the conveyor belt 1, and a panel 9 is provided inside the conveyor belt 1. The top surface of the panel 9 is arranged in contact with the inner ring surface of the conveyor belt 1, and both sides of the panel 9 are installed on the frame 5. The printing device 8 is installed above the conveyor belt 1.

[0023] In this embodiment, a plurality of hidden grooves 12 are provided on the inner side surface of the conveyor belt 1, and a through hole 13 passing through the annular bar 3 is provided on the inner wall surface of the hidden groove 12. Fixed sleeves 14 are embedded and installed on both sides of the conveying groove 2 opposite the through holes 13, and the connecting parts are installed in the fixed sleeves 14 through the through holes 13.

[0024] In this embodiment, the connecting parts include a screw 15 and a rotating block 11. One end of the screw 15 passes through the relative through hole 13 and is inserted into the fixed sleeve 14, and is threadedly connected to the fixed sleeve 14. The rotating blocks 11 are installed on the other end of the screw 15. The rotating blocks 11 are hidden in the hidden groove 12, and a cross groove is provided on the outer end face of the rotating block 11.

[0025] In this embodiment, a pressure plate 6 is provided on one side of the conveyor belt 1 located at the printing device 8, and multiple connecting plates are installed between the pressure plate 6 and the frame 5. One end of the printing paper 4 is inserted between the conveying trough 2 and the pressure plate 6. Both sides of the printing paper 4 are in contact with the annular strip 3, the top surface of the printing paper 4 is in contact with the pressure plate 6, and the bottom surface of the printing paper 4 is in contact with the conveying trough 2.

[0026] In this embodiment, the frame 5 is provided with mounting holes at positions opposite to the driven roller 10 and the driving roller, and sealed bearings are installed in the mounting holes. The roller shafts on the driven roller 10 and the driving roller are installed in the inner rings of the sealed bearings. A motor 7 is installed on the frame 5, and the rotating shaft of the motor 7 is fixedly connected to the roller shaft at one end of the driving roller. The motor can drive the rotation of the driving roller, and the driving roller can drive the rotation of the conveyor belt.

[0027] In this embodiment, the annular strip 3 is made of rubber material, and the outer ring surface of the annular strip 3 is set flush with the outer ring surface of the conveyor belt 1. The annular strip is an open ring body, so during installation, it can be put into the conveying groove and realize a closed loop by adhesion.

[0028] In this embodiment, the inner diameter of the hidden groove 12 is set larger than the inner diameter of the through hole 13, so that after the rotating block is set in the hidden groove, the rotating block is larger than the inner diameter of the through hole, which prevents the rotating block from entering the through hole. The outward moving screw and rotating block can press the annular strip onto the conveyor belt to prevent it from loosening.

[0029] When in use, the width of the conveying trough is first adjusted according to the width of the printing paper. When adjusting, different numbers of ring strips are directly put on. After the ring strips are added, the width of the conveying trough will be reduced until it matches the width of the printing paper. After the ring strips are put on, connectors of different lengths are prepared, and the screws on the connectors are inserted into the fixed sleeves through the corresponding through holes and are threadedly connected with the fixed sleeves. The rotating block on the connector is hidden in the hidden groove to avoid protrusion and affecting the conveying of the printing paper.

[0030] After the above is completed, the printing paper can be placed in the conveying trough and pass through the channel between the pressure plate and the conveying trough. The printing paper can be pressed on the conveyor belt by the pressure plate, and the two sides of the printing paper can be limited by the annular bar. After the conveyor belt rotates, it can directly push the printing paper toward the printing equipment. During the movement, the conveyor belt and the printing paper move synchronously to ensure the stability of the movement, so that the printing paper is centered and deviation is avoided to ensure the quality of printing.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
