Energy-saving linear bottle blowing machine

Abstract

The invention discloses an linear bottle blowing machine. The bottle blowing machine comprises a frame, wherein the frame is provided with a heating module, a blowing module and a base-moving device; the base-moving device is arranged between the heating module and the blowing module; the base-moving device comprises a longitudinal guide rod, a transverse guide rod, bottle base seats, a telescoping mechanism, a first push-and-pull mechanism and a second push-and-pull mechanism; multiple bottle base seats can be movably sleeved on the transverse guide rod, the two adjacent bottle base seat are in serial connection through the telescoping mechanism, the first push-and-pull mechanism pushes the transverse guide rod to move back and forth, and the second push-and-pull mechanism acts on the outermost bottle base seat to separate the bottle base seats. By adopting the structure, the bottle blowing machine of the invention can grasp bottle bases side by side, effectively avoid the phenomenon that the bottle bases are grasped alternately and heated repeatedly and save energy; the movement of changing distance is simple and fast, thus effectively increasing the work efficiency and creating more economic benefits; and telescoping mechanism can be fast disassembled and displaced so as to adapt to various blowing modules and increase the use flexibility of the bottle blowing machine.

Description

technical field [0001] The invention relates to the technology in the field of blow molding machines, in particular to a linear blow molding machine characterized by low energy consumption, flexible use and high efficiency. Background technique [0002] Beverage companies have two urgent needs for bottle blowing equipment. One is that due to the continuous rise in the price of plastic raw materials, beverage companies are always thinking about how to reduce packaging costs to maximize profits. Therefore, it is necessary to use advanced bottle blowing equipment to produce products with lighter weight. Second, due to the rapid changes in the market, beverage manufacturers must respond flexibly to the shorter and shorter life cycle of beverages. Correspondingly, the increasingly frequent product updates in the production of PET bottles, in the production process It is necessary to continuously improve the efficiency of blow molding. These two urgent needs have presented a big ...

Problems solved by technology

[0009] Although the above-mentioned existing blow molding machine structure can provide users with the effect of blow molding preforms in batches, it is indeed progressive, but in actual use, it is found that there are still many deficiencies in its own structure and performance. , causing the existing bottle blowing machine to fail to achieve the best use effect and work efficiency in practical application, its shortcomings are summarized as follows:

[0010] 1. The structure and action of the two types of embryo ejection mechanisms in the prior art are relatively complicated, and there are many parts and large volumes, which are not convenient for assembly, are not conducive to saving production costs, and are not conducive to the improvement of work efficiency.

[0011] 2. For the preform transfer device in the prior art, the efficiency of this kind of bottle blowing machine that grabs preforms at intervals is still low, and the action is relatively complicated, and because the preforms that are side by side are grabbed at intervals, the rest are not grabbed The preforms are repeatedly heated in the preheating area, which is still not conducive to energy saving

This kind of bottle blowing machine that uses screw pitch change is also limited by the screw rotation rate, which also makes the efficiency of the blow molding machine low, and the screw mass is relatively large, and the force required to drive the screw is greater and consumes more energy. The position setting between the preform holders, if the distance between two adjacent preforms set on the blow molding area changes, the entire screw needs to be replaced, which makes the flexibility of the screw limited

[0012] 3. The one-to-one production mode in the prior art seriously restricts the speed of preform blow molding, but the production efficiency of blow molding is not significantly improved by relying on the one-to-one production mode
