Description

Technical Field

[0001] The utility model relates to the technical field of bottle blank production and manufacturing, in particular to a bottle blank clamping device. Background Art

[0002] The preform is formed by injection molding under the working conditions of the injection molding machine by filling the raw materials into the gun mold of the mold at a specific temperature and pressure. It is formed by injection molding and becomes a semi-finished intermediate product, and then becomes a terminal product through blow molding.

[0003] The blow molding equipment is connected to a conveyor line. The existing method is to manually place the manufactured preforms on the conveyor line that is transported to the blow molding equipment. This is inefficient and requires manual inspection of whether the preforms are qualified before placing them on the conveyor line. The equipment has a long standby time and is not in line with the production efficiency of the enterprise. Employees need to bend over to grab and inspect the preforms after production and then place them on the conveyor line. Employees work for long hours, with high labor intensity, and long-term bending is not conducive to the health of their lumbar spine.

[0004] To this end, it is necessary to design an automated equipment that can automatically grab the bottle blanks and put them on the conveyor line. After manual inspection, the bottle blanks that have passed the inspection will be moved to the conveyor line. The bottle blanks are then transported to the blow molding equipment for the next process. Utility Model Content
