Facilitate the reflux of hot water, hot and cold water cycle is accelerated, beneficial to taking away heat.
It is preferred that the lower compression roller includes pressure roller cooling portion, the pressure roller cooling portion is internally provided with the first hollow area,
The cold water inflow entrance is inserted with a cold water pipe, and the cold water pipe is inserted to the centre position more than first hollow area.
This programme enables cooling water sufficiently into lower compression roller, cooling pressure roller cooling portion.
It is preferred that the material of the cold water pipe is stainless steel.
It is preferred that the water outlet is arranged with into water tube hose, it is described enter water tube hose extend to the cold water pipe；It is described enter water
Muzzle is equipped with Return water hoses, and the Return water hoses being arranged on the water inlet extend to the return water outflux.
It is preferred that the water outlet and water inlet of the cooling-water machine are designed with valve.
This programme makes it possible to control the temperature of lower compression roller by controlling the flow of the cooling water of cooling-water machine, on allowing
Pressure roller stabilization improves the sintering efficiency of polytetrafluoroethylene (PTFE) in suitable temperature.
It is preferred that the lower compression roller is connected and sealed with the seal cap by rubber seal.
This programme causes the cooling water in lower compression roller will not be revealed to cause equipment fault.
The positive effect of the utility model is：
By the utilization of the utility model, the temperature of lower compression roller during sintering polytetrafluoroethylene, is reduced, controls,
The waste heat on the upper pressure roller that pressure roller movement is carried out with lower compression roller has been taken away so that in the rubber that the top of upper pressure roller is laid with not
It can be damaged because of high temperature, reduce the sintering cost of polytetrafluoroethylene (PTFE), improve the sintering efficiency of polytetrafluoroethylene (PTFE).
