The cooling system for the PVB extruding film is characterized in that a water inlet end of a refrigerator is communicated with a cooling water tank while a water outlet end of the refrigerator is communicated with a water storage tank; a film extruding device is arranged on the cooling water tank; the film extruded by the device is fed into the middle part of the cooling water tank to be subjected to water cooling and curing and then is output by a transmission mechanism; a water inlet pipe connected with the water storage tank is arranged at the lower part of the cooling water tank; a pressure pump is arranged on the water inlet pipe; and a watermark-free water inlet mechanism is arranged at the water inlet pipe in the cooling water tank. The cooling system for the PVB extruding film has the advantages that a constant water temperature is ensured, and the surface of the PVB film is free from the quality problems such as watermarks and water prints after being cured and taken out of water.
Description
Technical field
The utility model belongs to the technical field of PVB film extruder equipment, refers in particular to a kind of cooling system of PVB extruded film.
Background technology
The PVB intermediate coat is to melt extrusion molding by the heat of diaphragm extruder, and the diaphragm temperature of moulding is very high, and the film surface has strong viscosity, can not be used for production and processing, the rolling of packing link in later stage at once, therefore, need diaphragm with extrusion molding through one refrigerating work procedure, form and solidify diaphragm.
In the water cooling operation, normally the pvb film of extruding is involved in the water storage device cooling equably by carry-over pinch rolls, again along the carry-over pinch rolls water outlet, this process relaxes average rate, PVB film surface after the curing is without the water wave phenomenon, meet quality standard, yet the very fast heat that distributes because of diaphragm of water in the water storage cooler bin heats up, and the cooling curing effect reduces, therefore water storage cooler bin domestic demand arranges EGR, do not stop to replenish cold water and discharge hot water, temperature constant in the guard box produces spray or ripples but adopt common water feed apparatus to make easily in the cooler bin, cause the pvb film surface to produce the water wave phenomenon, affected the quality of product.
Summary of the invention
The purpose of this utility model provides a kind of cooling system of PVB extruded film.
The purpose of this utility model is achieved in that
The cooling system of PVB extruded film, the water inlet end of refrigeration machine is communicated with cooling water tank, the water side is communicated with storage tank, the cooling water tank top is provided with the diaphragm extrusion device, the diaphragm that this device is extruded enters to be exported by transmission mechanism after cooling water tank middle part water-cooled is solidified, it is characterized in that: the bottom of cooling water tank is provided with the water inlet pipe that is connected with storage tank, water inlet pipe is provided with compression pump, and the water inlet pipe in the cooling water tank is provided with calmization water intake mechanism.
Above-mentioned calmization water intake mechanism is: bending arranges water inlet pipe towards the cooling water tank bottom surface, and water inlet pipe mouth is equipped with filter core and filter screen.
The bending angle of above-mentioned described water inlet pipe is 90 degree, and water inlet pipe adopts stainless steel material to make, and caliber is 100mm.
Above-mentioned filter screen is inside and outside two-layer, and the spacing distance of inner filter screen and outer filter is 5cm, all adopts stainless steel material to make.
Above-mentioned inside and outside two-layer filter screen is respectively 120 purpose inner filter screens and 240 purpose outer filters.
The filter area of above-mentioned inner filter screen is 10cm * 20cm, and the filter area of outer filter is 20cm * 30cm.
The intake pressure of above-mentioned compression pump control is 0.1Mpa.
The utility model compared to existing technology outstanding and useful technique effect is:
Water circulation of the present utility model be from water inlet pipe mouth at the bottom of storage tank, be provided with simultaneously double-layer leaching net, greatly reduced the cushion effect of water inlet, make cold water enter the storage tank bottom, do not produce macroscopic spray, ripples, bubble, being connected with delivery port on storage tank top derives hot water, has guaranteed constant water temperature, and the PVB film surface after the curing water outlet is without the quality problems of water wave, water mark.
Description of drawings
Fig. 1 is structure principle chart of the present utility model.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:
The cooling system of PVB extruded film, the refrigeration machine 2 that comprise storage tank 1, is communicated with storage tank and cooling water tank 3, the cooling water tank top is provided with diaphragm extrusion device 4, the diaphragm 5 that this device is extruded enters to be exported by transmission mechanism after cooling water tank middle part water-cooled is solidified, the bottom of cooling water tank is provided with the water inlet pipe 6, the top that are connected with storage tank and is provided with the outlet pipe 7 that is connected with refrigeration machine, water inlet pipe is provided with compression pump 8, and the water inlet pipe in the cooling water tank is provided with calmization water intake mechanism.Water inlet pipe is arranged on the below of diaphragm position, has avoided the impulse force of water inlet directly to affect diaphragm, and this discharge outlet is located at the top of diaphragm position, by the water circulation convection current, discharged by hot water.
Above-mentioned calmization water intake mechanism is: bending arranges water inlet pipe towards the cooling water tank bottom surface, and water inlet pipe mouth is equipped with filter core 9 and filter screen.
