Blowing machine

Abstract

The invention provides a blowing machine, and belongs to the technical field of plastic machining. The blowing machine solves the problem that an existing blowing machine is poor in production efficiency and comprises a rack, a rotating disc and multiple blowing die opening and closing devices; the rotating disc is rotatably connected with the rack, the blowing die opening and closing devices are circumferentially distributed around the axial core line of the rotating disc, the blowing die opening and closing devices and the rotating disc are connected through a radial guide structure enabling the blowing die opening and closing devices to move along the radial line of the rotating disc; the blowing die opening and closing devices are connected with the rack through a set of annular guide structures with the annular guide track lines; a straight line segment is arranged in each guide track line. The blowing machine has the beneficial effects of being high in raw material utilization rate, high in product production efficiency, high in product yield, low in noise, convenient to operate, and capable of reducing the number of workers and reducing labor intensity of the workers.

Description

Technical field [0001] The invention belongs to the technical field of plastic processing, and relates to a mold opening and closing device, particularly a blow molding machine. Background technique [0002] Plastic bottle is a kind of polyester (PETG), polyethylene (PE), polypropylene (PP) as raw materials, adding corresponding organic solvents, and after high temperature heating, through the plastic mold through the preform blow molding, extrusion or blowing Injection molded plastic container. Plastic bottles are mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs. [0003] In the process of manufacturing plastic bottles by the extrusion blow molding process, first use an extruder to shape and cut into a plastic tube strip of a suitable blow molding machine processing length, and then put the plastic tube strip into the mold of the blow molding machine for blo...

Problems solved by technology

In order to improve production efficiency and reduce the number of workers, people think of using manipulator-assisted processing solutions, that is, using manipulators to replace some processes, but the production efficiency is still difficult to meet the needs of some customers
