Damage-free preform conveyor

Abstract

The invention relates to the technical field of bottle preform production, in particular to a damage-free preform conveyor. The damage-free preform conveyor comprises a support, a chain transmission assembly, a preform carrying assembly and a preform receiving assembly. The chain transmission assembly is mounted on the support, the preform carrying assembly is mounted on the chain transmission assembly, and the preform receiving assembly is mounted on the front side of the support. During preform receiving, bottle preforms are transferred to the preform carrying assembly located under a preform outlet mechanism from the preform outlet mechanism through the preform receiving assembly, and the preform carrying assembly loaded with the bottle preforms moves to the rear side of the support through the chain transmission assembly. The damage-free preform conveyor has the beneficial effects that after the bottle preforms are turned over through the preform outlet mechanism, openings of the bottle preforms are downward, inserting rods of the preform receiving assembly stretch out of preform bearing parts until the inserting rods stretch into the bottle preforms and abut against the innerbottoms of the bottle preforms, meanwhile, the bottle preforms are loosened by the preform outlet mechanism, the bottle preforms fall on the inserting rods, the inserting rods retract, and the preformbearing parts are stably sleeved with the bottle preforms. The whole process is stable in operation, the bottle preforms and the preform bearing parts are not in hard contact collisions, and it can be guaranteed that the inner and outer walls of the bottle preforms are not scratched to a large degree.

Description

technical field [0001] The invention relates to the technical field of bottle embryo production, in particular to a non-damaging embryo transfer machine. Background technique [0002] With the continuous development of my country's economy, my country's beverage market has developed very rapidly in recent years, and the demand for preforms is also increasing. Society and beverage manufacturers have higher and higher requirements for food hygiene and safety, production sites are getting tighter and labor costs are getting higher. Therefore, the requirements for automation and cleanliness of production equipment are getting higher and higher. [0003] The preform is the prototype of Baote before forming. Its tube wall is thick and transparent, and it can be sealed with a general plastic bottle cap. The preform is generally injection molded with a hot runner mold. In the field of preform packaging automation technology, preforms are packed into empty cages by the packing mach...

AI Technical Summary

Problems solved by technology

At present, a preform ejection mechanism is installed below the discharge port of the injection molding machine, and the preform is temporarily stored in the embryo cavity by the preform ejection mechanism. When it comes out, the temperature is 45-55°C, and the surface temperature is relatively high. After falling on the conveyor belt, the collision between the preform and the conveyor belt may cause deformation and affect the product quality. Even if it is cooled, it falls on the conveyor belt and is transported outward. During the process, the outer wall of the preform is also easily scratched, which affects the appearance of the product
