Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a device for removing static electricity from paper in a printing workshop. Background Art

[0002] The main component of paper used for printing is plant fiber, and the water content of paper changes with temperature and humidity. When the humidity of paper is too low, the paper is prone to static electricity, and workers often feel electric shocks. Static electricity is more active at a relative humidity of 30%, and the lower the humidity, the more active the static electricity is. It gradually weakens with increasing humidity and basically disappears in an environment with a humidity of more than 50%. Static electricity on paper will frequently cause paper adhesion, paper feeding difficulties, and paper mutual repulsion during the printing process, greatly affecting the printing efficiency. When the paper is too dry, the printing ink will also induce static electricity. If it is discharged during the printing process, "static ink spots" may appear on the printed product, thereby affecting the printing quality. A destaticization device is needed to solve the above problems. Utility Model Content

When the blower motor 7 drives the spiral blades 8 to rotate, the ions ionized by the discharge needles 9 can be transported to the neutralization chamber 101 to neutralize the charges on the paper pile 4.

[0016] In this embodiment, the sliders of the electric track 2 on both sides of the neutralization chamber 101 are connected to the two ends of the crossbar 301 of the paper pusher 3, the middle part of the crossbar 301 is rotatably connected to the middle part of the rotating rod 302, and the lateral support rods at both ends of the rotating rod 302 are rotatably connected to the middle part of the support tube 303, and the support tube 303 body is in contact with the rightmost paper of the inclined paper pile 4 (reference direction in the figure). When the electric track 2 drives the crossbar 301 forward, the paper pusher 3 can push the paper pile 4 to fit with the body of the paper feeding tube 5 in the paper feeding mechanism, and the paper feeding mechanism includes a driving motor 10, which is installed on the outside of the housing 1, and the gear at the output end of the driving motor 10 is meshed with the gear at the end of the paper feeding tube 5, and the paper feeding tube 5 is rotatably connected to the two sides of the outlet end of the neutralization chamber 101, and the bottom of the paper feeding tube 5 is in clearance with the belt surface of the conveyor belt 6. When the driving motor 10 drives the paper feeding tube 5 to rotate, the paper feeding tube 5 can roll the paper in the paper pile 4 onto the conveyor belt 6, and the conveyor belt 6 carries the paper through the humidification mechanism.

[0017] In this embodiment, the humidification mechanism includes an evaporation pool 11, and the electrode 12 in the evaporation pool 11 is connected to an external AC power supply through a contactor 13.

After the paper is wetted, it is transported to the next process. After the conveyor belt 6 is transmitted to the bottom, the roller group 16 wipes off the excess water to avoid interference with the next transportation.

[0020] The utility model can electrically neutralize the paper pile 4 in the neutralization chamber 101 through ion wind, so that the paper feeding roller 5 can transfer the papers one by one to the conveyor belt 6. The humidifying mechanism passed by the conveyor belt 6 can adjust the humidity of the papers, further preventing the generation of static electricity, reducing the generation of paper adhesion, paper feeding difficulties, paper repulsion and the like, and improving the printing quality and efficiency of the printing workshop.
