Description
Technical field
The utility model relates to membrane production equipment technical fields, and in particular to a kind of film production chill roll.
Background technique
Film is during processing, very high from the high-temperature fusion shape plastic film temperature for extrusion of getting to know, it usually needs
It is cooled and shaped on chill roll.The type of cooling of chill roll is divided into air-cooled and water cooling, and the cooling effect of water cooling is better than air-cooled
Cooling effect.Existing water-cooled chill roll uses unilateral water inlet, and cooling water at this time is intelligently enough cooled to close inside roll body
The position of water inlet pipe, during heat exchange, water inlet end temperature is lower, and water outlet temperature is higher, influences the quality of production of film.
Meanwhile the intracavitary cooling medium of its roller of existing chill roll and the surface heat exchanging effect of roller chamber are poor, the self cooling ability of chill roll is poor.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of film production chill rolls, it can solve existing
The cooling problem that roll surface temperature is uneven, self cooling result is poor in technology.
To solve the above-mentioned problems, the utility model uses following technical scheme:
The utility model provides a kind of film production chill roll, including roll body and refrigeration mechanism, and the roll body includes interior
Roll body and outer roll body, the outer roll body are hollow structure, and the interior roll body is solid construction, and the interior roll body is set to described outer
The inside of roll body and with outer roll body be coaxially disposed, cooling chamber, the cooling chamber are formed between the outer roll body and the interior roll body
Interior to be equipped with annular baffle, the annular baffle connects the inner wall of described outer roll body one end, the length of the annular baffle
Less than the length of the outer roll body, spillway hole is evenly distributed on the barrel of the annular baffle, the outer roll body connects institute
The one end for stating annular baffle is equipped with water inlet and water outlet, and the water inlet is set to the interior roll body and the circular ring shape is kept off
Between plate, the water outlet is set between the outer roll body and the annular baffle, the water inlet and the water outlet
The refrigeration mechanism is connected by rotary joint respectively.
The refrigeration mechanism includes refrigerating chamber, refrigerator, cold medium delivery pipe, thermal medium as a preferred technical solution,
Delivery pipe and temperature sensor, the refrigerator connects the refrigerating chamber, is provided with temperature sensor in the refrigerating chamber, described
Cold medium delivery pipe connects the water inlet and the refrigerating chamber, and the thermal medium delivery pipe connects the water outlet and the system
Cold chamber.
As a preferred technical solution, the length of the annular baffle be equal to the outer roll body length five/
Four.
As a preferred technical solution, the interior roll body, institute's annular baffle, the outer roll body diameter of section be 1:2:
3。
Connected between the annular baffle and the end face of the outer roll body by fastener as a preferred technical solution,
It connects.
The film production chill roll of the utility model by being arranged annular baffle in cooling chamber, and water inlet with go out
The mouth of a river is set to one end, so that forming the return flow line of cooling medium in cooling chamber, the temperature difference occur in the both ends for avoiding roll body
Problem.The water (flow) direction of the spillway hole of annular baffle is radial, to cooling chamber the cooling water formation impact absorbed heat, and is upset
The laminar flow phenomenon of the cooling water of heat absorption makes the cooling water in cooling chamber sufficiently absorb heat before water outlet, reaches better cooling effect.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model film production cooling chamber.
