Roller type bottle preform separation mechanism of plastic bottle blowing machine

Abstract

A roller type bottle preform separation mechanism of a plastic bottle blowing machine comprises a separation base plate which is arranged on a bottle blowing machine rack, wherein linear guide rails are arranged on the base plate; at least two separation slide blocks which are driven by a power belt to move leftwards and rightwards are arranged on the linear guide rails; a preform clamping plate is mounted on each separation slide block; a preform clamping manipulator for clamping a bottle preform is mounted on each preform clamping plate; each preform clamping manipulator is provided with a forward-backward moving mechanism; a separation guide groove is formed in the separation base plate; a separation area A is formed in the separation guide groove; a roller is arranged in the separation guide groove; a connecting rod is movably connected to the roller; the separation slide blocks are connected through two separation rods which are folded through movable hinge pins; the two separation rods include a first separation rod and a second separation rod; the connecting rod is connected with the first separation rod. The mechanism has the advantages of being stable in mechanical action, long in separation distance, high in accuracy, accurate to position, and high in production efficiency.

Description

technical field [0001] The invention relates to a roller-type preform separation mechanism of a plastic bottle blowing machine, which belongs to the field of plastic machinery. Background technique [0002] Plastic hollow containers, such as mineral water bottles, oil bottles, etc., are processed by injection stretch-blow production technology. First, the plastic raw materials are injected into plastic preforms by an injection molding machine, and then the plastic preforms are put into a heater to heat and soften, and then the manipulators Clamped into a blow molding machine for stretch blow molding. In order to improve production efficiency, most of the mold stations in the bottle blowing machine are multi-stations, generally 2-6 stations. When the plastic preforms are heated in the heater, the shorter the distance between the preforms, the higher the heat utilization rate of the heater and the smaller the heat loss, but the distance between the molds in the blow molding m...

Problems solved by technology

Most of the existing preform spacing mechanisms use chain spacing or partition spacing, and cylinders are used as driving power at the same time. The disadvantages are poor precision, inaccurate positioning, high failure rate, high energy consumption, and high production costs.
