Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to a corrugated cardboard base paper feeder. Background Technology

[0002] A corrugated board production line, or simply a corrugated line, is a key production equipment for corrugated box manufacturers. It is the most important production line equipment in a carton packaging company, and includes several important components such as wet end equipment, dry end equipment, and production management system.

[0003] The patent with publication number CN208249448U discloses a paper feeder for corrugated cardboard. It includes a frame, on which a feeding component, a traction component, and a self-locking component are arranged in sequence. The traction component includes a first traction roller and a second traction roller arranged horizontally and rotatably connected to the frame at both ends. A third traction roller is arranged horizontally below the first traction roller and the second traction roller. This device solves the problem that the roll paper cannot be straightened due to unstable tension during conveying, and can ensure that the paper is always straight during conveying, thereby reducing the scrap rate in corrugated paper production.

[0004] However, this device requires feeding the paper roll according to its length using a feeding assembly. During the feeding process, the connecting blocks and correction wheels in the correction assembly need to be manually adjusted according to the width of the paper to limit the paper feeding from the paper boundary. This process is cumbersome and complicated, greatly increasing the complexity of paper installation and limiting the feeding, which affects paper feeding and production efficiency. To address this, a corrugated cardboard paper feeder is proposed to solve the problem of the existing paper feeder's difficulty in conveniently installing and limiting the feeding of the paper roll.

[0015] (III) Beneficial Effects

[0016] 1. The paper feeder for corrugated cardboard passes the end of the paper through the slot and tensioning mechanism. Then, the dual-shaft motor drives the lead screw and the linkage arm to move the limiting plate in the middle, limiting the paper roll in the middle of the placement box. During the process, the correction seat on the top of the fixed seat, together with the T-block in the T-slot, drives the correction wheel to move in the middle, so as to correct and guide the paper from both sides of the paper. The structure is simple and the operation is convenient, which solves the problem that it is difficult to conveniently install the limiting and conveying of the paper roll in the existing paper feeder.

[0017] 2. The paper feeder for this corrugated cardboard places the paper roll into the placement box and guides it out of the slot. Then, the cover is placed on the top of the placement box. At this time, the flexible scraper is in contact with the outside of the paper roll. When the paper roll is pulled out of the placement box, the flexible scraper scrapes off the dust and other impurities on the surface of the paper roll. At the same time, the dust pump is turned on, and the dust and other impurities are sucked into the dust collection box through the dust suction head on the dust suction pipe. This facilitates the cleaning of the paper roll surface and improves the quality of subsequent corrugated cardboard production. Attached Figure Description
