Description
Technical Field
The invention relates to the field of corrugated board conveying, in particular to a servo non-pressure dust removal paper feeder.
Background
Corrugated carton machinery has been developed from simple hand machines, semi-automatic machines to computer full-automatic machines in recent decades. The paper feeding part also generates chain manual paper feeding, paper pushing plate paper feeding driven by a crank guide rod, vacuum adsorption front edge paper feeding and the like according to different equipment and requirements. The chain paper feeding is that an operator puts a paper board on the paper feeding table and pushes the paper board to the lower part of a working roller by push plates on a plurality of rows of chains. Its advantages are high labour intensity, low efficiency and inaccurate paper feeding. The paper pushing plate paper feeding, the vacuum adsorption front edge paper feeding and the like are that paper boards are orderly stacked on a paper feeding table board, after work, the paper board to be printed or grooved is automatically pushed to the lower part of a conveying traction rubber roller, and the paper board is clamped to the lower part of a working roller by the rubber roller and a lower traction roller, so that continuous operation is realized. The problem arises that the positive pressure of the conveying pulling rubber roller and the lower pulling roller tends to crush corrugated paper boards, and the positive pressure is too small to pull out the paper boards from the lowest edge of the paper board pile. According to measurement and calculation, the positive pressure of the upper and lower traction rollers can reach more than 20 times of the pressure generated by the working rollers on the paperboard. Therefore, the strength of the corrugated board after printing, slotting or die cutting is reduced by at least 20 percent, and for a carton factory with strict requirements on the strength of the carton, the requirement is met only by increasing the gram weight of the corrugated board per square centimeter, and the cost of the carton is increased. According to preliminary statistics, the production capacity of a 100-sheet-per-minute aqueous printing and grooving machine is calculated according to the production net time of 5 hours per day and the working day of 200 days per year. The cost increased by increasing the gram weight of corrugated paper per square centimeter can reach 40-60 ten thousand yuan each year. Although the chain paper feeding does not have the phenomenon of collapse, the paper feeding precision is too low and the speed is too low. The paper feeding precision of the paper pushing plate and the front edge paper feeding precision are higher, but the crushing phenomenon exists, so the cost of the paper plate is increased.
The prior paper conveying mechanism without damaging corrugated boards has the following requirements for normal operation: 1. the fan generates sufficient wind power; 2. the automatic paper feeding part has to convey the paper board to the vacuum suction box and cover the suction opening, and the paper board can be adsorbed on the vacuum suction box only when the two conditions are met, and enough negative pressure is generated to ensure that the paper board has enough friction with the conveying roller wheel, so that the paper board can be continuously and accurately conveyed to the next working position. However, the process of the paperboard conveyed by the automatic paper feeding part does not have a dust removal process, and additional dust removal is needed in the subsequent process. And the conveying roller generates occlusion pressure on the paper board to press the corrugated paper board to damage and collapse.
