Technical field
The utility model is related to injection bottle base crystallization technique field, more particularly to crystal growing furnace heating arrangement.
Background technology
At present it is known that PET in industry（Polyethylene terephthalate）Bottle base in having the production process of Crystallization Procedure,
All it is first injection molding bottle base, then according to the difference of day temperature and moisture, deposits 7~15 days, fully inhaled inside warehouse
Water, waits bottle base to absorb after enough water satisfied crystallization production requirements, enters back into crystallization workshop and carries out Crystallization Procedure.Crystallization Procedure is
By being heated to bottle base bottleneck before crystallization, then natural cooling, by the crystallization process of PET raw materials, make bottleneck hardness and
Heat resistance increase, and in crystallization process, by controllable contraction process, makes after crystallization bottleneck size in critical field
It is interior.
Before Crystallization Procedure, the bottleneck size standard before crystallization is（Unit：mm）：
E（Bottleneck external diameter）Ф25.30±0.13；
T（Major diameter of thread）Ф27.96±0.13；
A（Relieving ring external diameter）Ф28.40±0.13；
D（Relieving ring height）14.50±0.13；
F（Support ring height）21.55±0.13；
In crystallization process, by controllable contraction process, the bottleneck size standard after crystallization is（Unit：mm）：
E（Bottleneck external diameter）Ф24.94±0.20；
T（Major diameter of thread）Ф27.43±0.25；
A（Relieving ring external diameter）Ф27.97±0.25；
D（Relieving ring height）14.10±0.20；
F（Support ring height）21.01±0.25；
In this manufacturing process, using existing heating arrangement, bottle base absorbs heat not enough fully and equal in crystallization process
It is even, influence final product quality.
The content of the invention
The purpose of this utility model is to provide a kind of heating arrangement for being molded bottle base crystal growing furnace so that bottle base was being crystallized

It is installed on inside crystal growing furnace, the second light tube group between first light tube group and the water baffle plate；
It is installed on inside crystal growing furnace, the preheating light tube group below first light tube group；
Wherein,
The fluorescent tube quantity of the preheating light tube group is four；
The fluorescent tube quantity of second light tube group is six；
The fluorescent tube quantity of first light tube group is two, and its angle irradiated is 20 °；
The water baffle plate is located at the corresponding graduated scale 75mm of the support ring.
In the heating arrangement of above-mentioned injection bottle base crystal growing furnace, the height of each fluorescent tube is in second light tube group
43mm；
The height of each fluorescent tube is 40mm in first light tube group.
The beneficial effects of the utility model are：The utility model is by changing the quantity of thermolamp pipe in crystal growing furnace heating arrangement
The position of change, fluorescent tube and the distance of bottle base, the irradiating angle of fluorescent tube and water baffle plate, makes heat absorption of the bottle base in crystallization process

Brief description of the drawings
Fig. 1 is the schematic diagram of heating arrangement in the prior art；
Fig. 2 is the schematic diagram of heating arrangement of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The application employs the scheme for changing heating arrangement position, by change each zone heating lamps pipe number change,
The problem of position of the distance of fluorescent tube and bottle base, the irradiating angle of fluorescent tube and water baffle plate is to solve to exist before not changing, so that
Product is set to reach property indices.
Referring to Fig. 1, be the schematic diagram of heating arrangement in the prior art, including water baffle plate 1 ', support ring 2 ', the first fluorescent tube
The 3 ', second light tube group of group 4 ' and preheating light tube group 5 '.In figure, 2., 6., 3. middle numeral represents the number of fluorescent tube in light tube group respectively
Amount, Fig. 2 is identical.
Referring to Fig. 2, the heating arrangement of injection bottle base crystal growing furnace of the present utility model, including be mounted on inside crystal growing furnace
