Description

Technical Field

[0001] The utility model relates to paper processing equipment, in particular to a high-stability paper feeding mechanism. Background Art

[0002] During the process of processing and finishing the paper, it needs to be transported through the paper feeding mechanism. When the paper is transferred at different stations, it needs to pass through some paperboards and conveyor belt structures. When the paper is sent out from the paperboard, its front end will naturally sag under the action of gravity, which will cause the drooping end of the paper to collide with other parts in the mechanism before contacting the conveyor belt, causing the paper to get stuck or deformed. Moreover, when contacting the conveyor belt, since it does not contact the end of the drooping part of the paper, it may also be squeezed and deformed, affecting the stability of paper transportation. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a high-stability paper feeding mechanism for solving the above-mentioned problems.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] A high-stability paper feeding mechanism comprises a paper feeding rack arranged at a paper feeding end, the paper feeding rack is provided with a paper feeding board, the paper feeding board is arranged with paper feeding guides, the feeding end of the paper feeding guide has a guide inclined surface extending upward, and a straight guide section is extended backward at the highest end of the guide inclined surface, a paper feeding conveyor belt is provided at the discharge end corresponding to the straight guide section, and the feeding end of the paper feeding conveyor belt is lower than the straight guide section.

[0006] One end of the paper feeding rack is hinged to the piston rod of the driving cylinder, and the swing of the paper feeding rack is arranged on the installation shaft.

[0007] An AC ion rod for eliminating static electricity is arranged between the paper feeding paper board and the paper feeding conveyor belt.

[0008] It also includes a guide plate arranged on the guide slope, wherein a bending portion is arranged at the bottom end of the guide plate, and the bending portion hooks the feeding end of the paperboard.

[0009] A first winding roller and a second winding roller are sequentially arranged at the feeding end of the paper conveyor belt, and the first winding roller is lower than the second winding roller, so that the paper conveyor belt forms an oblique lifting section between the first winding roller and the second winding roller.

[0010] The paper conveyor belt is provided with suction holes, and a first negative pressure seat is provided between the first and second winding rollers. The first negative pressure seat has a negative pressure cavity therein, and the negative pressure cavity is connected to the negative pressure machine. The first negative pressure seat is provided with an opening connected to the negative pressure cavity, and the opening can be connected to the suction hole on the paper conveyor belt.

[0011] A high-stability paper feeding mechanism of the above technical solution is provided with an additional paper feeding guide, and a guide slope is provided on the paper feeding guide to lift the incoming paper, and then the paper is conveyed and guided by a straight guide section, so that after the paper is lifted, the height at which it is sent out will be higher than the feed end of the paper feeding conveyor belt. At this time, although the paper will sag to a certain extent, the drooping end of the paper will first contact the conveyor belt to ensure that the paper can still be flattened and continued to be conveyed backward under the drive of the conveyor belt, thereby ensuring the stability and reliability of paper transportation.

[0017] As shown in the figure, the utility model disclosed includes a paper feed rack 8 arranged at the paper feeding end, a paper feed board 6 is arranged on the paper feed rack 8, and a paper feed guide 5 is arranged on the paper feed board 6. The feeding end of the paper feed guide 5 has a guide slope 3 extending upward. Further, it also includes a guide plate 2 arranged on the guide slope 3, and a bending portion 16 is arranged at the bottom end of the guide plate 2. The bending portion 16 hooks the feeding end of the paper feed board 6 to prevent the paper from getting stuck between the paper feed board and the paper feed guide 5, ensuring that the paper can be sent to the guide slope 3 for lifting and then transported backward. A straight guide section 4 is extended backward at the highest end of the guide slope 3, and a paper feeding conveyor belt 1 is arranged at the discharge end corresponding to the straight guide section 4, and the feeding end of the paper feeding conveyor belt 1 is lower than the straight guide section 4. Furthermore, one end of the paper feed rack 8 is hinged to the piston rod of the driving cylinder 7, and the swing of the paper feed rack 8 is set on the installation shaft 9. By controlling the driving cylinder 7, the paper feed rack 8 can be driven to swing along the installation shaft 9, thereby adjusting the angle position of the paper feed paperboard 6. An AC ion rod 15 for eliminating static electricity is arranged between the paper feed paperboard 6 and the paper conveyor belt 1, which can eliminate static electricity of the passing paper to ensure the stability of subsequent paper transportation. The first winding roller 10 and the second winding roller 13 are arranged in sequence at the feeding end of the paper conveyor belt 1. The first winding roller 10 is lower than the second winding roller 13, so that the paper conveyor belt 1 forms an oblique lifting section between the first and second winding rollers, which can further reduce the height of the paper feeding end of the paper conveyor belt 1. At the same time, the oblique lifting section can also better cooperate with the drooping end of the paper to drive the paper to be transported smoothly backward. A suction hole 14 is provided on the paper conveyor belt 1, and a first negative pressure seat 11 is provided between the first and second winding rollers. The first negative pressure seat 11 has a negative pressure cavity inside, and the negative pressure cavity is connected to the negative pressure machine. An opening 12 connected to the negative pressure cavity is provided on the first negative pressure seat 11, and the opening 12 can be connected to the suction hole 14 on the paper conveyor belt 1. With this structure, the paper can be adsorbed on the paper conveyor belt 1 for transportation, further ensuring the smooth transportation of the paper.

[0018] The working principle of the utility model is as follows: the paper is firstly sent to the paperboard 6, and is lifted upwards for transportation through the guide slope 3 of the paper guide 5, and then is guided and transported backwards along the straight guide section 4. The paper sent out from the paper guide 5 will sag to a certain extent. Since the paper feeding conveyor belt 1 is lower than the straight guide end 4, the drooping end of the paper will first contact the paper feeding conveyor belt 1 to ensure that the paper can still be flattened and continued to be transported backwards under the drive of the paper feeding conveyor belt 1.
