Abstract
The utility model relates to a heating device for bottle parison in the process of producing plastic packing bottles with the two-step method. The heating body is formed by that a plurality of aluminum shutterings are overlapped; a heating wire is arranged in the slot of each aluminum shuttering; an insulating plate is arranged between adjacent aluminum shutterings and corresponding heating holes on each aluminum shuttering form a baking chamber. The utility model has the advantages of no use of heating moulds, simple structure, sectional heating and temperature regulation to bottle parison and improved the quality of products.
Description
The utility model relates to a kind of bottle base heater that adopts two-step method to produce packing plastic bottle.
The process that adopts two-step method to produce packing plastic bottle is to outpour bottle base with injection machine earlier at present, use stretch blow machine stretch blow moulding again, before stretch blow, need bottle base is heated, the existing employing metal pattern of this heater two ends folder is gone up electric hot plate, the employing metal pattern that has is immersed in the liquid and heats, the shortcoming of above-mentioned heater is a complex structure, need do heated mould in addition.When processing some Packaging Bottle in addition, be different, and existing heater can't satisfy above-mentioned temperature requirements, influences the quality of Packaging Bottle for the temperature requirement of heating of bottle base upper, middle and lower section.
The purpose of this utility model provide a kind of simple in structure, can be to the plastic bottle blank heating cabinet of bottle base segmentation heating temperature control.
The utility model comprises heat-insulation layer 2 appended on casing 1, the casing 1, calandria is made of the mutual superposition of aluminum alloy pattern plate, place heating wire in the groove on the aluminum alloy pattern plate, between every adjacent two aluminum alloy pattern plates thermal insulation board is housed, all have bottoming hole on the every aluminum alloy pattern plate, consistency from top to bottom between the aluminum alloy pattern plate, corresponding bottoming hole is formed the baking chamber.
The utility model has the advantages that simple in structurely, easy to process, only need to bore some holes on aluminium sheet, do not need to do heated mould in addition, improved the density of arranging in baking chamber, can carry out segmentation heating temperature control to bottle base, the bottle comparatively complicated for the stretch blow shape provides convenience.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a vertical profile schematic diagram of the present utility model.
Fig. 2 is that the utility model A-A is to schematic diagram.
With reference to accompanying drawing: the utility model comprises heat-insulation layer 2 appended on casing 1, the casing 1, its calandria is made of aluminum alloy pattern plate 3,4,5 superpositions, place thermal insulation board 6 between the aluminum alloy pattern plate 3,4, place thermal insulation board 7 between the aluminum alloy pattern plate 4,5, in addition, add thermal insulation board 8 in aluminum alloy pattern plate 5 bottoms, all have groove on the every aluminum alloy pattern plate bottom surface, place heating wire 9 in the groove, all have bottoming hole on the aluminum alloy pattern plate 3,4,5, these bottoming holes of alignment back have constituted baking chamber 10 between the aluminum alloy pattern plate, and baking chamber 10 oral areas add insulating collar 11, prevent that heat scatters and disappears.The utility model can be made of two aluminum alloy pattern plates similarly.
Put into bottle base in baking in the chamber 10, regulate the heating wire at the bottom of the every aluminum alloy pattern plate, the sectional temperature-controlled heating of bottle base.
Claims (3)
1, a kind of plastic bottle blank heating cabinet, comprise upward appended heat-insulation layer (2) of casing (1), casing (1), it is characterized in that calandria is made of the mutual superposition of aluminum alloy pattern plate, place heating wire in the groove on every aluminum alloy pattern plate, between every two adjacent aluminum alloy pattern plates thermal insulation board is housed, all have bottoming hole on the every aluminum alloy pattern plate, consistency from top to bottom between the aluminum alloy pattern plate, corresponding bottoming hole are formed the baking chamber.
2, plastic bottle blank heating cabinet as claimed in claim 1 is characterized in that calandria is made of two aluminum alloy pattern plate superpositions.
3, plastic bottle blank heating cabinet as claimed in claim 1 is characterized in that calandria is made of three aluminum alloy pattern plate superpositions.
