Description

Technical Field

[0001] The present invention relates to the technical field of printing, particularly to the technical field of waste removal devices for printing presses. Background Art

[0002] A printing press is an important device on a cardboard production line. Waste is generated during the die-cutting output of the printing press. Therefore, a vibrating waste removal machine is generally provided behind the die-cutting output of the printing press.

[0003] The existing patent CN213674398U discloses a waste removal system for the die-cutting part of a printing press. It uses air pressure to make the cardboard leaving the die-cutting machine land stably on the paper receiving arm of the vibrating waste removal box. However, due to the uncontrollability of air itself, the cardboard is still prone to large offsets during the falling process.

[0004] The existing patent CN219294869U discloses a carton printing slotting die-cutting vibrating waste removal machine, which uses vibration to remove waste. However, during the vibration process of the cardboard and paper, some small powders will disperse due to vibration, which will instead cause the small powders to overflow everywhere and adhere to the cardboard, resulting in an unsatisfactory waste removal effect. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art and propose a waste removal device for a cardboard printing press, which can effectively remove waste from the cardboard, and the cardboard moves relatively stably, is not prone to scattering and accumulation.

A downward-sloping vibrating plate is arranged inside the box body. The end of the vibrating plate close to the feeding port is higher than the end of the vibrating plate close to the discharging port, and the lowest end of the vibrating plate is higher than the lowest end of the discharging port. A vibrating motor is fixed at the bottom of the vibrating plate, and several vibrating springs are fixed at the bottom of the vibrating plate. The vibrating springs are fixed inside the box body. Several waste removal holes are arranged on the vibrating plate, and the waste removal holes penetrate through the upper and lower ends of the vibrating plate. A dust suction pipe is connected to the box body, and the air inlet of the dust suction pipe is located below the vibrating plate. The dust suction pipe is connected to a dust suction device. The feeding plate slopes downward, passes through the feeding port, the feeding end of the feeding plate is located at the discharging end of the die-cutting mechanism of the printing press, and the discharging end of the feeding plate is directly above the feeding end of the vibrating plate. The discharging plate is fixed on the side wall of the box body where the discharging port is located, the discharging plate slopes downward, the joint of the discharging plate and the box body is the highest point of the discharging plate, and the upper end surface of the discharging plate is flush with the bottom wall of the discharging port.

Both the first waste clearing hole and the second waste clearing hole are strip-shaped. The first waste clearing hole is perpendicular to the inclination direction of the vibrating plate, and the second waste clearing hole is parallel to the inclination direction of the vibrating plate. The first waste clearing hole and the second waste clearing hole are spaced apart along the inclination direction of the vibrating plate.

[0009] Preferably, on both sides of the vibrating plate parallel to the inclination direction of the vibrating plate, a first baffle is fixed. The first baffle slopes upward from the joint with the vibrating plate in the direction away from the vibrating plate. A part of the feeding plate is located within the area clamped by the two first baffles.

[0010] Preferably, on both sides of the feeding plate parallel to the inclination direction of the feeding plate, a second baffle is fixed. The second baffle slopes upward from the joint with the feeding plate in the direction away from the feeding plate.

[0011] Preferably, on both sides of the discharging plate parallel to the inclination direction of the discharging plate, a third baffle is fixed. The third baffle slopes upward from the joint with the discharging part in the direction away from the discharging plate. The third baffle is fixed to the side wall of the box body. The mutually approaching sides of the two third baffles are flush with the two inner side walls of the discharging port respectively.

[0012] Preferably, a guiding plate that slopes downward is provided inside the box body. The guiding plate slopes downward from the side wall where the feeding port of the box body is located. The guiding plate is located below the vibrating plate. There is a gap between the guiding plate and the side wall where the discharging port of the box body is located.

[0015] Advantages of the present invention: By passing the feeding plate through the feeding port, the cardboard can stably fall onto the vibrating plate, enabling the cardboard to be arranged in an orderly manner on the vibrating plate, ensuring the orderliness of the cardboard. The settings of the first baffle, the second baffle, and the third baffle make it difficult for the cardboard to be severely skewed during movement, ensuring the stability of the cardboard movement and preventing it from piling up easily. The setting of the dust suction pipe enables some powders scattered during waste clearing to be promptly sucked away, avoiding secondary pollution caused by these powders.
