Abstract

The utility model belongs to the technical field of polyvinyl butyral (PVB) cooling systems and in particular relates to a cooling and temperature control system before PVB film rolling. A cooling pie of which the axis is parallel to a transmission roller is arranged after discharging a PVB film out of an oven and before rolling; a water circulation device is arranged on one side of the cooling pipe; the water circulation device is connected with a cooling box; the cooling box is connected with the cooling pipe for supplying water to the cooling pipe; a temperature monitoring probe is arranged above the cooled PVB film; the temperature monitoring probe transmits a signal to an infrared temperature monitor; and the infrared temperature monitor transmits the signal to the cooling box. The temperature of the PVB film which is discharged out of the oven and is cooled is monitored through the infrared temperature monitor, and the water temperature of the cooling box is regulated according to the tested temperature, so that the temperature of the cooled PVB film before rolling is controlled to be 25-28 DEG C, the rolling standard is reached, and the natural shrinkage rate of the PVB film before rolling is effectively controlled; and moreover, the system is suitable for the cooling link after discharging the PVB film out of the oven and before rolling.

Description

Cooling, temperature control system before the rolling of PVB film
Technical field:
The utility model belongs to PVB cooling system technical field, refers in particular to the rolling of a kind of PVB film preceding cooling, temperature control system.
Background technology:
Melt the PVB intermediate coat of extruding through elevated temperature heat, the surface has strong viscosity, and viscosity causes being difficult to separate after the rolling of PVB film, therefore, the PVB film that heat is melted after extruding is wanted to handle by water cooling earlier, make its cooling curing after, through a series of operation that dewaters, the side meets the rolling requirement again.In the end Yi Dao the operation that dewaters is to allow the PVB film enter the little baking of baking oven by carry-over pinch rolls dewater, the temperature that goes out the PVB film behind the baking oven rises to 40 ℃, PVB film under this temperature has retractility, under the tractive of carry-over pinch rolls, can produce and shrink irregular quality problems, therefore not meet the preceding quality inspection standard of rolling.
Summary of the invention:
The purpose of this utility model provides a kind ofly can effectively control the natural shrinkage factor of PVB film before rolling, refers in particular to out cooling, the temperature control system of PVB film before rolling behind the baking oven.
The utility model is achieved in that
Cooling, temperature control system before the rolling of PVB film, after the PVB film goes out baking oven, before the rolling, be provided with the cooling tube that axis is parallel to transfer roller, side at cooling tube is provided with water circle device, water circle device connects cooler bin, cooler bin connects cooling tube and supplies water to cooling tube, above cooled PVB film, be provided with the temperature monitoring probe, the temperature monitoring probe transmits signal and gives the infrared temperature monitor, and the infrared temperature monitor transmits signal and gives the water temperature of cooler bin with cooling water in the control cooling tube.
Above-mentioned cooling tube includes the parallel last cooling pipe of axis and reaches cooling pipe down, following cooling pipe is the rolling pipeline, last cooling pipe is passive pipeline, last cooling pipe and down cooling pipe compress from last cooling pipe and pass through between the cooling pipe down go out PVB film behind the baking oven.
Above-mentioned cooling tube is that stainless steel tube is made.
Above-mentioned infrared temperature monitor sends to cooler bin to signal by controller.
The advantage that the utility model is given prominence to compared to existing technology is:
1, the utility model is implemented going out the monitoring temperature of the cooled PVB film of baking oven by the infrared temperature monitor, regulate and control the water temperature of cooler bin simultaneously according to measured temperature, make the temperature control of cooled PVB film before rolling at 25-28 ℃, meet the rolling standard, effectively control the natural shrinkage factor of PVB film before rolling;
2, the cooling pipe of going up of the present utility model not only plays cooling effect with following cooling pipe, also plays draw;
3, the PVB film quality of the utility model cooling is stable;
4, the utility model be applicable to the PVB film go out baking oven after, the cooling link before the rolling.
Description of drawings:
Fig. 1 is simplified schematic diagram of the present utility model.
The specific embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1:
Cooling, temperature control system before the rolling of PVB film, after the PVB film goes out baking oven 1, before the rolling, be provided with the cooling tube that axis is parallel to transfer roller, side at cooling tube is provided with water circle device 9, water circle device 9 connects cooler bin 3 by pipeline, cooler bin 3 connects cooling tube by pipeline and supplies water to cooling tube, above cooled PVB film 6, be provided with temperature monitoring probe 7, temperature monitoring probe 7 transmits signal and gives infrared temperature monitor 8, and infrared temperature monitor 8 transmits signal and gives the water temperature of cooler bin 3 with cooling water in the control cooling tube.
Above-mentioned cooling tube includes the parallel last cooling pipe of axis 5 and reaches cooling pipe 4 down, following cooling pipe 4 is the rolling pipeline, last cooling pipe 5 is passive pipeline, last cooling pipe 5 and down cooling pipe 4 compress from last cooling pipe 5 and pass through between the cooling pipe 4 down go out PVB film 2 behind the baking oven, make its tight contact upper and lower cooling pipe 5,4, thus balancedly cooling.
Above-mentioned cooling tube is that stainless steel tube is made.
Above-mentioned infrared temperature monitor 8 sends to cooler bin 3 to signal by controller.
Operation principle of the present utility model:
PVB film 2 temperature that go out behind the baking oven reach 40 ℃, and this temperature is higher than tens degrees centigrade of rolling temperature, can produce to shrink irregular phenomenon.Therefore, must cooling pipe be set to the PVB film 2 that goes out behind the baking oven, the PVB film in the distraction procedure is implemented cooling curing.Recirculated water is delivered to cooler bin 3 through water circle device 9, make water become cooling water, the cooling water input is gone up in cooling pipe 5 and the following cooling pipe 4, makes cooling pipe 5 and following cooling pipe 4 not only play draw, also plays upper and lower cooling effect.The temperature of cooled PVB film 6 will meet 25-28 ℃ normal temperature value before the rolling, if make cooled PVB film temperature higher or on the low side with room temperature and other reasons, also can occur shrinking irregular or make PVB film surface the water smoke phenomenon occur, for this reason, still can not directly carry out rolling, must implement monitoring temperature to cooled PVB film 6.Temperature monitoring probe 7 is set above cooled PVB film 6, temperature monitoring probe 7 passes to infrared temperature monitor controller 8 with the PVB film temperature signal that records, by overheat controller signal is sent to cooler bin 3 simultaneously, according to the height of temperature, adjust the temperature of cooling water.
Above-described embodiment only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
