Bottle base mouth cooling device in the bottle blowing machine
Technical field
The present invention relates to the beverage machine field, refer more particularly to a kind of device that on the bottle blowing machine bottle base mouth is cooled off that is used in.
Background technology
China beverage industry was rapidly developed in recent years, and beverage manufacturing enterprise is except expanding the scale of production, and it is extremely thin that many enterprises also make the injection moulding of bottle base mouth, reduces the materials cost of bottle with this.Bottle base heats in the pot arch of bottle blowing machine, because the bottle base oral area is too thin, is heating regular meeting's distortion often, and the serious bottle of bottle base mouth distortion just can't spiral cover, becomes waste product.In order to prevent that the bottle base mouth is out of shape in heating furnace, existing bottle blowing machine all is provided with cooling device in heating furnace, this cooling device comprises the pedestal that is arranged in bottle blowing machine bottle blowing mouth side, pedestal is provided with baffle plate, baffle plate is used for stopping that the light that heats fluorescent tube shines directly on the bottle base mouth, prevents bottle base mouth heating distortion, and also be provided with the cooling water circulation canal on pedestal, be used for cooling base and baffle plate, guarantee that pedestal and baffle plate at high temperature can not be out of shape.Though the cooling device of said structure has played the effect of protection bottle base mouth to a certain extent, along with working long hours of heating furnace, near the temperature of the air the bottle base mouth still can be more and more higher, and the bottle base mouth still can temperature distortion.
Summary of the invention
Technical problem to be solved by this invention is: thus a kind of bottle base mouth cooling device that can keep for a long time in the bottle blowing machine that near the air themperature bottle base mouth effectively prevents the distortion of bottle base mouth will be provided.
For addressing the above problem, the technical solution used in the present invention is: the bottle base mouth cooling device in the bottle blowing machine comprises the pedestal that is arranged in bottle blowing machine bottle blowing mouth side, pedestal is provided with baffle plate and cooling water circulation canal, the pedestal that is positioned at baffle plate below is provided with cooling air channels, and the base outer wall that is positioned at baffle plate one side is provided with the venthole that several communicate with air duct.
Described pedestal is the pair of base that is arranged on bottle blowing mouth both sides in the bottle blowing machine.
The invention has the beneficial effects as follows: the gas outlet of cooling air is set below baffle plate, makes the cooling air be sprayed directly on on the bottle base mouth, reduce near the temperature of the air of bottle base mouth, prevent that the bottle base mouth from deforming because of being heated.

The specific embodiment
Below in conjunction with accompanying drawing, the bottle base mouth cooling device in the bottle blowing machine of the present invention is described in further detail.
As shown in Figure 1, the bottle base mouth cooling device in a kind of bottle blowing machine comprises the pedestal 1 that is arranged in bottle blowing machine bottle blowing mouth 8 sides, in order better to reach the purpose of cooling bottle base mouth, pedestal is set at a pair of when reality is used, and is positioned at the both sides of bottle blowing mouth 8.Pedestal 1 is provided with baffle plate 2 and cooling water circulation canal 3, and the pedestal 1 that is positioned at baffle plate 2 belows is provided with cooling air channels 4, and pedestal 1 outer wall that is positioned at baffle plate 2 one sides is provided with the venthole 5 that several communicate with air duct 4.The quantity of gas outlet 5 is decided as required.
Operation principle of the present invention is: as shown in Figure 1, the present invention is installed in bottle base mouth 6 both sides, and baffle plate 2 close bottle base mouths, venthole 5 is aimed at bottle base mouths 6.In cooling water circulation canal 3 and cooling air channels 4, feed cooling water and compressed air respectively subsequently, cooling water circulates in cooling water circulation canal 3, reduce the temperature of pedestal 1, prevent that pedestal 1 is subjected to for a long time heating the irradiation of fluorescent tube 7 and thermal deformation takes place.Baffle plate 2 stops to fall that the light of most heating fluorescent tube 7 shines on the bottle base mouth 6, compressed air then blows out from venthole 5 by cooling air channels 4, blow on bottle base mouth 6, form the process of a step-down, Compressed Gas becomes the process that low pressure is again individual heat absorption from high pressure simultaneously, thereby bottle base mouth 6 temperature are reduced.Eliminate the phenomenon that deformation takes place because of temperature is too high bottle base mouth 6, made the production line continuously to work, improved production efficiency.
