In delivery port.
In order to facilitate the spacing distance of adjacent tank is controlled, meet the optimal cooling curve of polyethylene sheath material, preferably
Technical scheme is that the sliding block of sink bottom is equipped with guide rail, and the axial direction of guide rail is consistent with extrusion molding tie rod discharging direction, draws
Flow tube is telescoping tube, and keeper is provided between sliding block and guide rail, and keeper is used for the precalculated position that sliding block is fixed to guide rail.
When production environment temperature is too low, extrusion molding tie rod and Air Temperature Difference are big between tank, heat exchange amount increase, cause cooldown rate
Whard to control, in order to avoid above-mentioned phenomenon, preferable technical scheme is that directive wheel includes the first directive wheel and the second directive wheel,
First directive wheel is arranged on the feed side and exit side of the inner chamber bottom of tank, and the second directive wheel is used to lead in extrusion molding tie rod
Go out drainage tube.
Preferable technical scheme is that keeper is bolt.
The advantages of the utility model and beneficial effect are：
The cooling system structure of the high density polyethylene (HDPE) protective cover material is reasonable, by setting drainage tube between tank, or
The bosh in road supplements hot water backward by way of upper underflow stream, reduces the use of heater in tank, makes full use of
The heat of extrusion molding tie rod in itself, help to save the energy consumption of cooling system.
