Abstract
The utility model relates to a convection cooling device of a polyethylene film blow moulding machine, which belongs to a moulding apparatus for plastic films, particularly a blow moulding apparatus. The convection cooling device comprises a hollow air guide cylinder which is arranged on the upper part of a machine head. The utility model is characterized in that the lower part of the air guide cylinder is provided with a horn flow guide cover which is communicated with the air guide cylinder, and a fixed support is arranged around the bottom periphery of the flow guide cover and is provided with more than one through hole. The utility model has the advantages of simple structure, convenient installation and low cost.
Description
Technical field
The utility model belongs to the cooling device of plastic sheeting former, specifically is a kind of poly-second film blow molding machine convection type cooling device.
Background technology
Poly-second film blow molding machine must cool off fast to film when the poly-second film that blows than minor diameter, can guarantee that the poly-second film diameter that blows out remains unanimity, thereby guarantee the quality requirement of poly-second thin-film width.Mostly the poly-second film blow molding machine of prior art is external cooling air radiator cooler if being adopted, though this external cooling air radiator cooler has guaranteed the ordinary production of poly-second film, but Chang Yin is difficult to guarantee the even cooling to the film bubble, influenced the product quality of poly-second film, the conforming defective of film diameter appears influencing, how to solve this defective, be industry technical staff problem demanding prompt solution always.
The utility model content
In order to overcome the deficiency that exists in the existing above-mentioned technology, the utility model provides a kind of poly-second film blow molding machine convection type cooling device, this poly-second film blow molding machine convection type cooling device can guarantee the even cooling to the film bubble, satisfies the quality requirement of poly-second thin-film width.
The technical solution adopted in the utility model is:
A kind of poly-second film blow molding machine convection type cooling device, comprise the hollow gas cylinder that is arranged on head top, it is characterized in that the gas cylinder bottom is provided with the horn-like kuppe connect with it, and the periphery of ring kuppe bottom is provided with fixed support, encircles on the fixed support 1 above through hole is set.
The height of above-mentioned gas cylinder is greater than the height of horn-like air scoop.
The utility model can guarantee the even cooling to the film bubble, satisfies the quality requirement of poly-second thin-film width.And have characteristics simple in structure, easy for installation, cheap.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model example structure schematic diagram.
The specific embodiment
Before the equipment ordinary production, earlier the utility model is fixedly installed to as shown in Figure 1 head 4 tops of blow moulding machine.
When the equipment ordinary production, after the poly-second film that blow moulding machine blows out forms film bubble 2, be enabled in the wind cooled cooling air device that install the top of blow moulding machine frame, the film bubble 2 of the poly-second film that blow moulding machine is blown out cools off.The air of heat mainly entered kuppe along the through hole on the kuppe bottom bracket 3 when film bubble 2 blew out, discharge from gas cylinder 1 top that links with it along kuppe again, it is descending that the higher air of temperature of discharging steeps 2 inwalls along with the reduction of temperature along film, descending air is after the hot air that is blown out by head 4, enter kuppe once more, discharge along gas cylinder and cooled off once more.Gas in the film bubble 2 is circulative convection and so forth, and just making film steep 2 peripheries can cool off uniformly.Avoided prior art even to film bubble inhomogeneous cooling because of the outer cooling air of film bubble 2, cause hot and cold cross-ventilation direction disorder in the film bubble easily, the film bubble is difficult to the inconsistent problem of poly-second film diameter that evenly cooling causes, thereby the poly-second film that blow moulding machine is blown out can keep the diameter unanimity.
Because of the utility model simple in structure, easy for installation, cheap, so do not increase the production cost of blow moulding machine integral device substantially.
Claims (2)
1, a kind of poly-second film blow molding machine convection type cooling device, comprise the hollow gas cylinder that is arranged on head top, it is characterized in that the gas cylinder bottom is provided with the horn-like kuppe that connects with it, and the periphery of ring kuppe bottom is provided with fixed support, on the ring fixed support 1 above through hole is set.
2, poly-second film blow molding machine convection type cooling device according to claim 1 is characterized in that the height of the height of gas cylinder greater than horn-like air scoop.
