Background
A bottle blowing machine is an apparatus for heating an injection molded bottle blank tube (referred to as a "bottle blank") and blowing the bottle blank heated to a certain temperature into a mold with air of a suitable pressure to form a bottle, and generally includes a feeding unit, a conveying unit, a heating unit, a blow molding unit, a finished product taking-out unit, and the like. The bottle blanks are conveyed to the conveying unit from the feeding unit, conveyed to the heating unit by the conveying unit, heated to a preset temperature, conveyed to a mold of the blow molding unit for blow molding, and finally conveyed out by the finished product taking-out unit. In order to improve the production efficiency, the mold in the blow molding unit is required to blow two bottle preforms simultaneously to form a finished product, and in order to heat the bottle preforms uniformly, the bottle preforms are generally moved continuously at a constant speed on the upper conveying unit, but before the bottle preforms are fed into the blow molding unit, the distance between the two bottle preforms needs to be changed, so that the distance between the two bottle preforms corresponds to the distance between the two bottle preforms blown by the mold, and therefore, the bottle preforms need to be subjected to pitch adjustment.
