Description

Novel corrugated roller

Technical Field

Relates to a corrugating roller for processing corrugated boards.

Background

Corrugated boxes are the most widely used green and environmentally friendly packaging products. The corrugated case is made of corrugated board, the corrugated board is made of a corrugated board production line, the core of the corrugated board production line is a corrugating machine, the corrugating machine takes corrugating rollers as core components, and comprises a middle corrugating roller (1), an outer corrugating roller (2), a pressure roller (3), a glue coating roller (4) and a glue homogenizing roller (5), and the 5 rollers are taken as typical representative characteristics.

The single-sided corrugated board (8) is produced by ironing, meshing and forming corrugated medium paper (6) at the central connecting line of a middle corrugated roller (1) and an outer corrugated roller (2), continuously attaching the single-sided corrugated board to the surface of the middle corrugated roller (1) through a positive pressure type or negative pressure type vacuum device, and then applying glue solution with a certain thickness to the top of the single-sided corrugated board when the single-sided corrugated board runs to a glue spreader (4), wherein the thickness of the glue solution can be regulated and controlled through a glue spreader (5), then continuously attaching the single-sided corrugated board to the surface of the middle corrugated roller (1) and then running to the central connecting line of a pressure roller (3), and bonding the single-sided corrugated board with preheated inner paper or middle paper (7) under the action of temperature and pressure.

When the single-sided corrugated roll paper board (8) runs to the pasting machine through systems such as a platform bridge and a deviation rectifying system, glue solution with certain thickness is applied to one corrugated side by a glue coating roller of the pasting machine, then the glue solution and the preheated surface paper (9) or the single-sided corrugated paper board (8) enter a double-sided machine together, and the glue solution and the preheated surface paper board or the single-sided corrugated paper board are bonded into a three-layer corrugated paper board (10) or a five-layer corrugated paper board (11) or a seven-layer corrugated paper board at.

The corrugation type of the corrugated roller consists of three parts, namely a corrugation top circular arc (aa), a corrugation bottom circular arc (bb) and a corrugation side line segment or a circular arc (ab) connecting the corrugation top circular arc (aa) and the corrugation bottom circular arc (bb), and then a series of corrugation type parameters of the corrugated roller, such as corrugation height, corrugation distance, included angle, wrap angle and the like, are derived according to different density positions of the corrugation top circular arc and the corrugation bottom circular arc. The structure of the flute top circular arc, the flute bottom circular arc and the flute side line segment or the circular arc can be a non-single structure, the radius of the flute top circular arc refers to the total circular arc radius and is expressed by (R), the radius of the flute bottom circular arc is expressed by R, usually the radius of the flute bottom circular arc R is about 0.30 larger than the radius of the flute top circular arc R, the difference value is used for supplying a gap required when the corrugated core paper passes through a meshing area of a corrugating roller, the prior method is to carry out omnibearing calculation and analysis on technical indexes such as a total wrap angle, a tension factor, a forming meshing force, core paper tension change and the like through independently developed interactive computer program professional software, carry out simulation operation and stress analysis through the professional computer software, and the difference value can be properly adjusted according to the conditions such as flute type parameters, the flute type technical content, the gram weight of the operated core paper and the like.

The sizes of the corrugated top arcs of the traditional upper corrugated roller and the traditional lower corrugated roller are the same, namely the size of the radius (r 1) of the corrugated top arc of the middle corrugated roller (1) is the same as that of the radius (r 2) of the corrugated top arc of the outer corrugated roller (2), so that no distinction between (r 1) and (r 2) exists, r is uniformly used for representing the corrugated top arcs, and the corrugated radiuses of corrugated paper boards produced by the traditional corrugated structure corrugated rollers are also the same.

The gluing condition of the pasting machine is different from that of a single-side machine, the riding roller or the pressing rod or the pressing roller of the pasting machine can inevitably cause the deformation of the corrugated at the top of the corrugated core paper to a certain degree, and even under the regulation and control of the glue homogenizing roller, the gluing amount of the corrugated board at the pasting machine is still inevitably different from that at the single-side machine, namely the gluing amounts of the corrugated paper with the same corrugated radius at the single-side machine and the pasting machine are different.

The main component of the glue solution is water, the difference of the glue application amount on the two sides of the corrugated board is the main reason of warping of the paper board, the large glue application amount is also the main reason of foaming of the paper board, and less glue solution is used for smaller corrugated radius.

The size of the arc of the top of the corrugated roller directly influences the sizing amount, the sizing width and the bonding effect of the top of corrugated paper of the corrugated board, the paper rate of the corrugated roller, the service life of the corrugated roller, the size of the total wrap angle and the tension factor of the meshing area of the corrugated roller, and the indentation condition and the strength of the corrugated board. The improvement of the flute shape is usually very tiny, but even if the flute is not, taking the most common B flute as an example, a corrugated board has more than 150 flutes, and a little improvement of one flute can not be seen after being amplified; if the average speed of the corrugated board production line is 150 meters per minute, a few improvements of one flute are calculated in one year, and all the improvements are considerable numbers.

Disclosure of Invention

The utility model provides a novel flute corrugated roller, the flute top arc size of flute corrugated roller is inequality, promptly the flute top arc radius (r 1) of well flute roller (1) of flute roller is inequality with the size of the flute top arc radius (r 2) of outer flute roller (2), and the flute top arc radius (r 1) of well flute roller (1) is greater than flute top arc radius (r 2) of outer flute roller (2) under normal condition, nevertheless a novel flute corrugated roller does not receive (r 1) and the restriction of (r 2) big or small of the size of knowing, and the preferred numerical value of the absolute value of both differences is 0.05 mm's multiple.

The limit deviation of tooth profile of a corrugated roller is +/-0.02mm according to tooth profile precision of a corrugated roller of a QB/T1447.1-2000 single-face corrugated paperboard machine, so that the defined standard values of different sizes of crest arcs of the corrugated roller are as follows: the absolute value of the difference value between the arc radius (r 1) of the ridge top of the middle corrugating roll (1) and the arc radius (r 2) of the ridge top of the outer corrugating roll (2) is larger than 0.05mm, namely the arc radii of the ridge top of the corrugating rolls are different, and the arc radii of the ridge top refer to the total arc radii.

The novel corrugated roller comprises a factory finished corrugated roller and a half-finished corrugated roller after flute type fine grinding, wherein the radius of the arc of the flute top of the corrugated roller refers to the radius of the arc of the total flute top, the radius of the arc of the flute top is determined by detecting and analyzing results of a contourgraph, a projector, an electron microscope and other detecting means as a defining standard, one of the three detecting means can be selected, the three detecting means have the same legal efficacy, and the defining standard is not limited by the three detecting means.
