Background
1. Corrugated boxes are the most widely used green and environmentally friendly packaging products. The corrugated case is made of corrugated cardboard, the corrugated cardboard is made of corrugated cardboard production line, the core of the corrugated cardboard production line is corrugating machine, the core part of the corrugating machine is corrugating roller, the corrugated paper as the core characteristic of the corrugated cardboard is corrugated core paper and is formed by ironing and meshing of the corrugating roller, the corrugated structure on the surface is the first characteristic of the corrugating roller, the three most main parameters of the corrugated structure are corrugation height, corrugation distance and corrugation top circular arc in sequence, the improvement of the corrugation is usually very tiny, but not really, taking the most common B corrugation as an example, 1 meter of corrugated cardboard has more than 150 corrugations, one point of one corrugation is improved, and the improvement can not be seen after being amplified; if the average production speed of a corrugated board production line is 150 meters per minute, a little improvement of one flute is a considerable number calculated in one year.
2. The corrugating machine takes a corrugating roller as a core component and comprises: the corrugated paper board comprises a middle corrugated roller (1), an outer corrugated roller (2), a pressure roller (3), a glue coating roller (4) and a glue homogenizing (scraping) roller (5), wherein the 5 rollers are typical representative characteristics; the corrugating machine has the function of producing a single-sided corrugated board (8), wherein the single-sided corrugated board (8) is formed by ironing and meshing corrugated medium paper (6) at the meshing position of the central connecting line of a corrugating roller, is attached to the surface of a middle corrugating roller (1) through positive pressure type (wind pressure type) or negative pressure type (vacuum adsorption), and then is adhered to the surface of the middle corrugating roller (1) when running to a glue spreader (4), glue solution with certain thickness is applied to the top of the corrugated paper by the glue spreader (4), the thickness of the applied glue solution can be adjusted through a glue homogenizing (scraping) roller (5), and when the corrugated paper continuously runs to the central connecting line of a pressure roller (3) and the middle corrugating roller (1), and preheated inner paper (or middle paper) (7) are adhered into the single-sided corrugated board (8) under the effects.
3. The most ideal forming state of the corrugated medium paper is as follows: the corrugated roller is ironed and meshed to form only at the meshing part of the central connecting line of the corrugated roller, the smaller the contact total wrap angle in the meshing area of the corrugated roller is, the better the contact total wrap angle is, and the optimal numerical value is zero. In order to distinguish the essential difference between the corrugated roller and the gear, the tooth form or tooth form of the corrugated roller is called as the flute form or the flute form, which is also called by the industry in a more professional way.
4. The most standard structure of the traditional flute type of the corrugating roll consists of three parts, namely a flute top arc R, a flute bottom arc R and a flute side line section ab externally tangent to the flute top arc aa and the flute bottom arc bb.
5. The leno side ab has two functions: firstly, connecting a ridge top arc aa and a ridge bottom arc bb; and secondly, the flute side clearance required when the high-gram-weight corrugated medium paper (6) passes is provided by optimizing the flute side clearance.
6. The function of the fillet bottom arc bb is three: firstly, the corrugated medium paper is matched with the arc aa of the ridge top to finish ironing and meshing forming of the corrugated medium paper; secondly, supplying the corrugated medium paper to pass through the meshing area to reach the required gap at the meshing position through the difference value of aa radius of the circular arc of the corrugated top; thirdly, the corrugated roller obtains better positioning through the meshing with the arc aa of the corrugated top, and the deviation and the vibration are reduced.
7.

8. The corrugated top arc aa of the corrugated roller with the traditional corrugated structure is characterized in that: the stupefied top arc aa is composed of a section of stupefied top arc r, and when the stupefied profile is measured and analyzed by a professional contourgraph, points are randomly selected on the stupefied top arc, and the obtained numerical values are the same.
CN 102019720B corrugating roll flute profile three circular arc structure, its full-text has expressed traditional flute profile corrugated roll flute crest circular arc faithfully and comprises a section flute crest circular arc r.
CN 103707560A is an M-shaped corrugated roller, which expresses that the crest arc of the corrugated roller with the traditional flute structure is composed of a section of crest arc r.
CN 103692702A corrugating roll flute type T bone flute type structure, its full-text has faithfully expressed that traditional flute type structure corrugating roll flute top circular arc comprises a section flute top circular arc r.
The function of the arc aa of the corrugation top can be seen that the arc aa of the corrugation top is one of the key points of the corrugation type optimization design of the corrugated roller, but the corrugation type of the corrugated roller is optimized by simply increasing or reducing the radius of the arc r of the corrugation top, so that the advantages of the arc aa of the corrugation top are taken, the disadvantages of the arc r of the corrugation top are avoided, and the technical problem to be solved by the invention is how to take the advantages of the arc aa of the corrugation top and avoid the disadvantages of the arc r of the corrugation top.
