AI Technical Summary
Existing equipment struggles to achieve precise alignment between the bottle spout and bottom and the central axis of the bottle body during the bottle manufacturing process, resulting in low product qualification rates and limited production efficiency.
The self-locking bottle centering forming mechanism includes the cooperation of guide rods, limiting components, and stretching components. The coaxial setting of the guide rods and stretching components and the limiting of the limiting rods ensure the centering of the preform during the stretching process. Precise centering is achieved through the support components of the bottle bottom mold sealing device of the blow molding machine.
This improved the yield rate of bottle molding, prevented the bottle bottom from deviating from the central axis, ensured the regularity of the bottle's appearance and its sealing performance, and improved production efficiency and product quality.
