Abstract

The invention discloses a cooling device for a blow-molded plastic barrel of a blow-molding machine. The cooling device comprises a supporting mechanism, a gas supply rotary base drive mechanism whichis arranged on the supporting mechanism, a gas supply rotary base which is connected with the gas supply rotary base drive mechanism, a rotary arm fixed base which is fixed with the gas supply rotarybase, a rotary cooling platform, a central gas supply tube and an upper shaft column, wherein a platform rotary arm fixed interface is arranged on the outer wall of the rotary arm fixed base; a platform rotary arm is arranged on the platform rotary arm fixed interface; the lower part of the platform rotary arm is equipped with a platform rotary arm gas tube connecting nozzle; a plastic barrel static clip is arranged on the rotary cooling platform; a plastic barrel movable clip drive mechanism is arranged on the horizontal cantilever end of the rotary cooling platform; a gas spraying mechanismand a gas return mechanism are arranged on the middle part of the rotary cooling platform; the upper end of the central gas supply tube is positioned in the gas supply rotary base, and the lower endof the central gas supply tube is fixed with a supporting mechanism; and the upper end of the upper shaft column is connected to a cooling gas lead-in tube, the lower end of the upper shaft column isfixed with the upper part of the central gas supply tube, and the middle part of the upper shaft column is positioned in the rotary arm fixed base. The cooling device relieves online operating strength, ensures cooling effect and efficiency, prevents thermal radiation from harming a body, and is good in automatic effect.

Description

technical field [0001] The invention belongs to the technical field of cooling facilities, and in particular relates to a cooling device for blow molding plastic barrels by a blow molding machine. Background technique [0002] The blow-molded plastic barrels mentioned above mainly refer to plastic barrels with a relatively large volume such as 200L or more. Such large-volume or large-capacity plastic barrels need to be cooled after blowing. In the past, stochastic cooling was usually used for cooling large-capacity plastic barrels, that is, cooling in the mold of the blow molding machine. This cooling method is performed under the control of the mold, so the plastic barrels are less likely to be deformed, but due to random It takes a long time to cool down with the mold, which affects the blow molding efficiency of the blow molding machine. The natural cooling method after the mold is released has relatively little impact on the blow molding efficiency of the blow molding m...

In the past, stochastic cooling was usually used for cooling large-capacity plastic barrels, that is, cooling in the mold of the blow molding machine. This cooling method is performed under the control of the mold, so the plastic barrels are less likely to be deformed, but due to random It takes a long time to cool down with the mold, which affects the blow molding efficiency of the blow molding machine

The natural cooling method after the mold is released has relatively little impact on the blow molding efficiency of the blow molding machine, but the plastic barrel is prone to deformation during the cooling process, and in severe cases it will be scrapped

[0003] In the published Chinese patent literature, it can be seen that the technical information on blow molding plastic barrels blown by blow molding machines is cooled by compressed air, typically such as CN205058424U recommending "a cooling device for plastic barrels", although this patent solution is to a certain extent However, by reading the full text of the patent specification, it is not difficult to find that it has the following shortcomings: First, due to the cooling process of the plastic barrel after it is released from the mold It needs to be operated by the on-line operator with a hand-held cooling device, so the labor intensity of the on-line operator is high; second, because multiple plastic barrels cannot be cooled at the same time, the cooling efficiency is low. In order to meet the requirement of manufacturing speed, additional workers must be added, resulting in a waste of valuable labor resources; third, because the cooling time and cooling uniformity of the plastic barrels that have just been released from the mold are still at high temperature are completely controlled by people. Will, so the cooling effect is difficult to guarantee, because the quality of the cooling effect is related to factors such as the experience, sense of responsibility, emotion and even physical fitness of the workers; The degree of heat radiation is serious, and the working environment is relatively harsh or even harsh, and there is a risk of harming the health of workers
