Technical Field
The invention relates to the technical field of packaging machines, in particular to a distribution design method of hot cutting roller heating wheels of a pillow type packaging machine based on circumference equal division.
Background
Although the existing wheel cutting structure of the pillow type packaging machine can seal the plastic packaging bag, the sealing effect is poor, the sealing lines of the film end are not clear, the production quality is poor, and a circumferential distributable design space exists in a rotating main shaft. The invention designs a novel wheel cutting mechanism by carrying out optimization design and structure adjustment on the original wheel cutting mechanism, and aims to improve the production efficiency.
For example, chinese patent discloses a reciprocating end sealing device of pillow type packaging machine (patent No. CN201510009669.1), which includes a gear driving mechanism, a rotary driving mechanism and an end sealing mechanism connected in sequence, wherein the end sealing mechanism includes an upper end sealing component and a lower end sealing component with opposite rotation directions. The sealing device has the advantages that the sealing time of the packaging film arranged between the upper end sealing component and the lower end sealing component is prolonged, and the sealing effect is improved.
However, the wheel cutting packaging device of the packaging machine can only ensure the cutting effect by prolonging the closing time between the cutting textures, so that the production time is prolonged, the production efficiency of workers is reduced, the production period is long, and the time cost is high. Meanwhile, the extension design of the cutting knives on the circumference of the main shaft can be realized, the vacant space on the knife roll frame is fully utilized, and the processing number in unit circumferential motion is increased.
