A kind of air blowing type unloading device for bottle blowing machine

Abstract

The invention discloses an air blowing type blanking device for a bottle blowing machine, which comprises: a connecting base, a central rotating shaft is arranged on the top, driving pulleys are symmetrically arranged on the left and right sides of the central rotating shaft, and the outer sides of the driving pulley are A transmission belt is provided, the outer end of the transmission belt is provided with a driving pulley, and the shaft end of the driving pulley is connected with a stepping motor. The present invention clamps and stores the bottles conveyed by the conveying track of the bottle blowing machine through the symmetrically arranged inner and outer clamping rails, drives the inner and outer clamping rails to rotate through the central rotating shaft, and turns the inverted bottles upright and moves them at the same time The inner clamping rail and the outer clamping rail are transferred to the opposite side to connect with the blanking transmission slide rail, and the bottle on the caliper can be blown and translated to the blanking transmission slide rail through high-pressure gas to complete the blanking without manual operation , At the same time, there are multiple caliper structures on the outside of the central rotating shaft, which is convenient for completing the loading and unloading work at the same time, and is convenient for further production efficiency.

Description

technical field [0001] One or more embodiments of this specification relate to food packaging production equipment, in particular to an air-blowing unloading device for a bottle blowing machine. Background technique [0002] Bottled beverages are generally stored in glass or plastic bottles, and plastic bottles are lighter and cheaper, so most of the existing bottled beverages are stored and transported in plastic bottles, and plastic bottles are generally produced by blowing machines. The raw material small plastic tube is heated and molded and then processed into a finished plastic bottle. Because the plastic bottle is relatively light, two clamping rails are usually used to clamp the neck of the bottle, and then transported by blowing with high-pressure gas. [0003] The applicant found that because the bottle is upside down when the bottle blowing machine is produced, and the bottle needs to be kept upright when the bottle is conveyed by high-pressure gas and rails, it i...

AI Technical Summary

Problems solved by technology

[0003] The applicant found that because the bottle is upside down when the bottle blowing machine is produced, and the bottle needs to be kept upright when the bottle is conveyed by high-pressure gas and rails, it is impossible to directly connect the discharge track and the transmission track of the blow molding machine. It is necessary to manually move the bottles produced by the blow molding machine to the transmission track, and the production efficiency is low. However, the general flip-type unloading device generally only has one flip arm and the corresponding moving rail, and cannot perform loading and unloading work at the same time. Moreover, the distance between the clamping rails is generally a fixed structure, which cannot be flexibly adjusted according to the size of the bottle, and the applicability and flexibility of use are low
