Description

Corrugated roller set gap adjusting structure of corrugated tip-to-tip board machine Technical Field The utility model relates to a tip-to-tip board machine, in particular to a corrugated roller set gap adjusting structure of a tip-to-tip board machine. Background At present, the paper board innovation of the tip to the tip is raised in the market, and takes four layers of corrugated paper boards as an example, wherein the four layers of corrugated paper boards comprise surface paper, inner paper and two layers of pit-see paper which are positioned between the surface paper and the inner paper and are pasted with the tip. However, in the production process of two layers of pit paper with the tips attached, two tip-to-tip corrugated rollers are required to respectively squeeze and heat the tips of two corrugated core papers (one of which is coated with glue) to realize attaching molding. Therefore, the gap adjustment requirement for the two corrugating rolls is high. At present, a plurality of patent publication documents of a tip-to-tip corrugating machine are only theoretical basis, and a gap adjusting structure of two corrugating rollers is not completely recorded, so that the production requirements of paper with different thicknesses are ignored. In addition, as the auxiliary corrugated rollers are respectively arranged beside the two corrugated rollers of the corrugated machine for producing the corrugated tip-to-tip paperboard and are used for respectively processing the upper corrugated medium paper and the lower corrugated medium paper, the gap adjusting structure of the corrugated roller set of the traditional corrugated machine cannot be directly applied. Disclosure of utility model The utility model aims to provide a corrugated roller set gap adjusting structure of a tip-to-tip board machine, which has the advantages of simple and reasonable structure and high adjusting precision and meets the requirements of paper with different thicknesses. The purpose of the utility model is realized in the following way: The corrugated roller set gap adjusting structure of the tip-to-tip board machine comprises a frame, a rocker arm, an upper corrugated roller and a lower corrugated roller, wherein the upper corrugated roller and the lower corrugated roller are opposite to each other, the upper corrugated roller is arranged on the frame, one end of the rocker arm is hinged with the frame, the lower corrugated roller is arranged on the rocker arm, the frame is provided with a buffer lifting mechanism for driving the rocker arm to swing upwards, and an inclined top gap adjusting mechanism for limiting the swing height of the rocker arm through a movable inclined plane, and tip gap adjustment between the upper corrugated roller and the lower corrugated roller is realized by changing the relative position of the movable inclined plane and the rocker arm. The aim of the utility model can be also solved by adopting the following technical measures: As a more specific scheme, the oblique jacking gap adjusting mechanism comprises an oblique block and a push rod, wherein the bottom surface of the oblique block is provided with a movable inclined surface which is in interference fit with the top of the other end of the rocker arm and is in sliding fit with the top of the other end of the rocker arm, and the push rod is arranged on the frame and used for pushing the oblique block to move transversely. As a further scheme, the top of the other end of the rocker arm is provided with a lower inclined plane which is abutted against the movable inclined plane of the inclined block. As a further scheme, a wedge block is arranged on the rocker arm and is in swing fit with the rocker arm, and the top surface of the wedge block is provided with the lower inclined surface. As a further scheme, the inclined block is in transverse linear sliding fit with the frame. As a further scheme, the push rod is a screw rod, the screw rod is in threaded connection with the rack, and one end of the screw rod is in running fit with the inclined block. As a further scheme, the buffer lifting mechanism is an air cylinder or an oil cylinder. As a further scheme, an anti-collision limiting mechanism used for limiting the rising height of the rocker arm is further arranged between the frame and the rocker arm, and collision between the upper corrugated roller and the lower corrugated roller is avoided. The upper corrugated roller and the lower corrugated roller jointly act to extrude the first wavy corrugated paper, the lower corrugated roller and the auxiliary lower corrugated roller jointly act to extrude the second wavy corrugated paper, and the sizing mechanism is used for applying the corrugated tip of one of the wavy corrugated paper, and the upper corrugated roller and the lower corrugated roller jointly act to relatively attach the corrugated tip of the first wavy corrugated paper and the corrugated tip of the second wavy corrugated paper.
