Description

The manufacturing installation of heat resistant plastice bottle

The utility model relates to the processing of hollow plastic container, particularly the manufacturing installation of heat resistant plastice container.

Along with raising as can temperature such as tea beverage, the needs of heat resistant plastice beverage bottle have been proposed, because stretch blow processing is not carried out at the bottleneck position, so its processing is that the crystallization temperature that the parison oral area is heated to plastics is cooled off then, can obtain resistant to elevated temperatures bottleneck, the equipment that is used to process the heat resistant plastice bottle now all adopts existing parison preheating device or preheating, the plastic bottle manufacturing installation of stretch blow unification, or transform slightly, effect is undesirable, particularly the axle of the bottleneck portion of clamper is a metal, so heat conduction is fast, and the heat of heater is concentrated, and bottleneck portion heats up slow, required time is long, then the bottleneck distortion is big, and of poor quality, heat exhaustion is big.

The purpose of this utility model provides a kind of quick heating, and machining deformation is little, and crystalline quality is good, the manufacturing installation of energy-conservation heat resistant plastice bottle.

The purpose of this utility model is to realize by following technical scheme, the manufacturing installation of this heat resistant plastice bottle, has frame, the rotatable transportation sprocket that drives by power source on frame, chain, be fixed with the parison clamper on the chain, there is the heater of the hot type base substrate portion of being fixed on the frame side of parison clamper, also has the soaking sprocket wheel on the frame, the soaking chain, it is characterized in that said parison clamper has the fixture that is fixed on the chain, the rotatable axle that is loaded on the fixture, the lower end of axle is fixed with from rotary chain wheel, the upper end of axle is fixed with the heat resistant plastice seat, and the external diameter of heat resistant plastice seat matches with the internal diameter of parison oral area, saidly is meshed with said soaking chain from rotary chain wheel, in the horizontal position of said heat resistant plastice seat, be fixed with the heater of heating parison oral area on the frame.

The manufacturing installation of heat resistant plastice bottle of the present utility model, because the parison mouth area on clamper has adopted the heat resistant plastice seat, plastic seat heat conduction is slow, parison oral area heat is difficult for scattering and disappearing, so heating is fast, the time shortens greatly, crystalline quality is good, be out of shape little, energy savings.

Be explained in detail below in conjunction with the manufacturing installation of drawings and Examples heat resistant plastice bottle of the present utility model;
