DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, the present embodiment provides a paper leveling component of a paper stopper device of a printing press, comprising a base 1, a workbench 2 is fixedly provided on the top of the base 1, a reel 3 is fixed at the middle position of the workbench 2, the bottom of the reel 3 is attached to the base 1, the top of the reel 3 protrudes above the workbench 2, an inlet and outlet port 4 is opened on the top of the reel 3, the bottom end of the inlet and outlet port 4 is parallel to the plane of the workbench 2, the other end of the inlet and outlet port 4 is located above the workbench 2, a roller 5 is rotatably installed between the two ends of the reel 3, a driving motor is provided for the rotation of the roller 5, a conveyor belt 7 is rotatably installed on the inner side of the reel 3 located at the bottom of the inlet and outlet port 4, a conveyor belt 7 is provided between two groups of guide rollers 6, and the conveyor belt 7 is attached to the outside of the roller 5, the length of the conveyor belt 7 is greater than the length of the paper, a guide plate 8 is provided on the top of the inlet and outlet port 4, a placement groove 9 is provided at one end of the top of the workbench 2, a conveyor roller 10 is provided at the end of the top of the workbench 2 close to the placement groove 9, and a cleaning mechanism is provided at the end of the guide plate 8 close to the conveyor roller 10.

[0025] The overall working principle is as follows: after the printed paper is cut from the paper roll, the two ends of the paper are bent toward the top, and then the paper is adhered to the workbench 2 and slides toward the inside of the reel 3. When the paper passes through the inlet and outlet 4 and enters the inside of the reel 3, the driving motor will drive the roller 5 to rotate. There is a large friction between the roller 5 and the conveyor belt 7, so the conveyor belt 7 will be driven to rotate. The paper enters between the roller 5 and the conveyor belt 7. The roller 5 and the conveyor belt 7 squeeze the paper and do not slide relative to the paper, so the paper will not wear. At the same time, the paper is rewound between the roller 5 and the conveyor belt 7 to flatten the paper. Then the paper is pushed out from the inlet and outlet 4 at an angle upward, and moves horizontally toward the cleaning mechanism under the guidance of the guide plate 8. After cleaning, it is transported to the inside of the placement slot 9 through the conveyor roller 10.

[0026] In this embodiment, the outer side of the conveyor belt 7 is evenly provided with anti-skid patterns parallel to the length direction of the roller 5, and the outer side of the roller 5 is coated with an anti-skid coating.

[0027] Partial working principle: There is a large friction between the roller 5 and the conveyor belt 7, so the stable rotation of the conveyor belt 7 can be controlled, while ensuring the stable transportation of paper.

[0028] In this embodiment, a V-shaped inclined surface is provided at the bottom end of the guide plate 8, and the bottom of the guide plate 8 is coated with a smooth coating.

[0029] Partial working principle: When the paper enters from the inlet and outlet 4, it is guided downward by the surface at the bottom of the guide plate 8 so as to enter between the roller 5 and the conveyor belt 7. When the paper is pushed out, it is first guided upward at an angle and then conveyed horizontally.

[0030] In this embodiment, two groups of conveying rollers 10 are provided, and the two groups of conveying rollers 10 are located on a vertical plane and are in contact with each other. Conveying motors are provided at the ends of the conveying rollers 10 .

[0031] Partial working principle: When the paper is discharged from the inside of the reel 3, it passes between two sets of conveying rollers 10, and then is conveyed to the inside of the placement slot 9 under the thrust of the conveying rollers 10.

[0032] In this embodiment, the cleaning mechanism includes a hollow rectangular frame 11, a dust suction port 12, a dust removal box 13, a negative pressure fan 14 and a filter 15. The hollow rectangular frame 11 is fixed between the two sides of the top of the workbench 2. The inner top and the inner bottom of the hollow rectangular frame 11 are both provided with a dust suction port 12. The dust removal box 13 is installed at the bottom of the workbench 2. The filter 15 is installed at the end of the dust removal box 13 close to the reel 3, and the negative pressure fan 14 is installed at the end of the dust removal box 13 away from the reel 3. The end of the dust removal box 13 close to the reel 3 is connected to the interior of the hollow rectangular frame 11 through a pipe, and the input end of the negative pressure fan 14 faces the interior of the dust removal box 13.

[0033] Partial working principle: During the process of flattening and conveying the paper, it passes horizontally through the inside of the hollow rectangular frame 11, and the negative pressure fan 14 generates negative pressure inside the dust removal box 13. The gas enters through the dust suction port 12, thereby cleaning the upper and lower surfaces of the paper.

[0034] In this embodiment, a slot is provided on the dust removal box 13 below the filter 15 , and the filter 15 is inserted into the dust removal box 13 through the slot.

[0035] Partial working principle: The plug-in installation method makes the replacement of the filter 15 more convenient.

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
