Method for manufacturing plastic bottle and equipment thereof

Abstract

The invention relates to a manufacturing method of plastic bottles. Firstly, preforms are arranged inside a preheating device for preheating. Pre-heated preforms are conveyed into matched molds through a conveyance rack. A blow molding device is arranged on the matched molds. The blow molding device is injected into the preforms by using high pressure gas to make plastic bottles. A handle conveyor is arranged beside the conveyance rack, which feeds handles into corresponding clamping positions on the fringe of the cavity of the matched molds automatically. During blowing, the wall of the preforms expands and is bonded to the handles arranged at the fringe of the cavity of the molds. The invention also discloses an equipment to achieve the manufacturing method, which comprises a preheating device, a clamp device and a blow molding device. A preform conveyance rack is arranged between the clamp device and the preheating device. A handle conveyance device is arranged beside the conveyance rack. The invention improves the production efficiency of plastic bottles and is used safely and reliably.

Description

technical field [0001] The invention relates to a bottle blowing machine, in particular to a plastic bottle blowing machine with the functions of bottle preheating, blow molding and the like. Background technique [0002] At present, in the plastic processing industry, tubular preforms are used to blow plastic containers, such as oil tanks, soy sauce bottles, etc. The equipment generally used includes preheating, mold closing, blow molding and other processes. For the manufacture of plastic with handles For the bottle, when the preform is put into the clamping mold after preheating, manually put the handle into the corresponding position on the edge of the mold cavity, then close the mold, and use the blow molding device to blow out the plastics that people use every day. Containers, but due to the manual operation of placing the handle, the production speed is unstable and the production efficiency is not high. Accidents such as pinching may occur if you are not careful du...
