Movable-arm-adjustable fast switching body paper frame for corrugated board production

Abstract

The invention discloses a movable-arm-adjustable fast switching body paper frame for corrugated board production. The movable-arm-adjustable fast switching body paper frame comprises square frame body with a cavity structure. First movable arms and second movable arms are connected to the square frame body. Telescopic arms with chucks are arranged at one ends of the movable arms. The telescopic arms and the movable arms are provided with telescopic oil cylinders. One end of each first movable arm and one end of each second movable arm extend into the cavities. The parts, in the cavities, of the first movable arms and the second movable arms are provided with positioning pins. One end of each positioning pin extends into a positioning groove. The parts, in the cavities, of the first movable arms and the second movable arms are provided with toothed plates, the two toothed plates in the same cavity are arranged in a staggered mode, a gear is arranged between the two toothed plates in the same cavity, and the gears are connected with a motor arranged on one side of the square frame body. The movable-arm-adjustable fast switching body paper frame for corrugated board production has the advantages that the widths between the movable arms and the lengths of the movable arms can be adjusted, the requirements for production of body paper with different widths and radii can be met, the production investment can be reduced, and the body paper can be fast replaced.

Description

technical field [0001] The invention relates to a base paper frame for corrugated cardboard production, in particular to a fast switching base paper frame with adjustable movable arms for corrugated cardboard production. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand bumps and falls during handling. In the production process of corrugated cardboard, it is necessary to use the base paper bracket to hold up the base paper, and the base paper rotates around the axis for continuous production. The traditional base paper frame for corrugated cardboard is equipped with a movable arm on the frame body, and a chuck is installed on the top of the movable a...

AI Technical Summary

Problems solved by technology

The traditional base paper frame for corrugated cardboard is equipped with a movable arm on the frame body, and a chuck is installed on the top of the movable arm. The chuck is inserted into the shaft hole of the base paper and fixed. The movable arm is a fixed structure, and its spacing cannot be adjusted, so that the same bracket can only be used to hold the base paper with a fixed width size. When the size of the base paper is changed, the bracket needs to be replaced, resulting in increased production investment

At the same time, the traditional base paper rack for corrugated cardboard has only one set of movable arms and chucks. It takes a long time to replace a roll of base paper after it is used up, which wastes time and reduces production efficiency.

In addition, the arm length of the movable arm in the traditional technology has been fixed. When the radius of the base paper tube is too large, the arm length is not long enough, so that when the base paper tube has a large radius, it can only be produced by replacing the bracket. When it is small, because the arm length is longer than the radius of the original paper tube, the moment arm of the movable arm is larger during the lifting process, resulting in greater energy consumption of the equipment
