Abstract

The invention belongs to the technical field of glass bottle production, and discloses a glass bottle cold start-up rapid forming method, which is used for a preheating production stage of a rank machine, the forming method comprises positive blowing, initial mold cooling and mold forming cooling, and the opening timing of the positive blowing is delayed by 70-90 units of periodicity from the opening timing during normal production; the opening timing of the primary mold cooling is delayed by 15-25 units of periodicity from the opening timing during normal production, and the stopping timing of the primary mold cooling is advanced by 50-70 units of periodicity from the stopping timing during normal production; the start timing of mold forming cooling is delayed by 60-80 units of periodicity from the start timing during normal production; wherein the periodicity of one unit is alpha, and alpha meets the following formula: alpha=(t*N)/(360*V). The rejection rate of the glass bottles is greatly reduced and the cost is reduced by delaying the start timing and stop timing of positive blowing, mold forming cooling and initial mold cooling and reducing the cooling air of the bottle conveying machine.

Description

technical field [0001] The invention belongs to the technical field of glass bottle production, and in particular relates to a cold start-up rapid forming method for glass bottles. Background technique [0002] During the variety replacement of the row machine, the replaced molds are basically cold. The conventional timing of the machine section is not conducive to the forming of the glass bottle after the start-up. Often the forming is insufficient or some varieties cannot be formed, resulting in the glass bottle being broken and the material being trapped. The normal opening of machine bottles also causes a large amount of waste products to occur, wasting materials and increasing costs. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the object of the present invention is to provide a cold start-up rapid prototyping method for glass bottles. [0004] The technical scheme adopted in the present invention is: ...
