DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the embodiments:

[0022] like Figure 1-5 As shown, the utility model provides an air cooling device for forming a plastic barrel, comprising a machine tool 1, a conveying mechanism 4 is fixedly installed on the top of the machine tool 1, an adjusting mechanism 2 is fixedly installed on the top of the machine tool 1, an air cooler 8 is fixedly installed on the left inner wall of the adjusting mechanism 2, a plate heat exchange mechanism 9 is through-connected to the right end of the air cooler 8, a pressure tank 7 is through-connected to the bottom of the plate heat exchange mechanism 9, a blowpipe 6 is through-connected to the bottom of the pressure tank 7, a fixing mechanism 5 is fixedly installed on the top of the conveying mechanism 4, and a plastic barrel 3 is clamped and fixed on the fixing mechanism 5.

[0023] The air cooler 8 is a device for generating cold air. The refrigerant is repeatedly cooled by a refrigeration cycle through components such as a compressor, a condenser, an evaporator, and an expansion valve inside the air cooler 8, and the generated cold air is blown into the air duct of the plate heat exchange mechanism 9, and heat is exchanged with the natural wind flowing in the opposite direction of the air duct in the plate heat exchange mechanism 9. The air cooler 8 blows cold air into the plate heat exchange mechanism 9. The heat exchange between these two devices is a closed cycle, that is, the cold air source is flowing between these two devices. Another air duct in the plate heat exchange mechanism 9 is a natural circulation air duct 95. After heat exchange with the cold air source, the natural air after heat exchange is transferred from another air duct to the blow pipe 6 by the pressure tank 7, and the pressure tank 7 is a pressure vessel installed between the plate heat exchange mechanism 9 and the blow pipe 6. Under the specified pressure, the natural air after heat exchange is compressed and output from the other end for the blow pipe 6 to blow into the plastic barrel 3, and then blow cold air into the plastic barrel 3. The blow pipe 6 is one of the key components for air cooling and shaping of the plastic barrel 3. It is installed above the mouth of the plastic barrel and is responsible for blowing cold air into the plastic barrel 3, so that the hot plastic placed in it can be quickly cooled and solidified, which can greatly shorten the cooling and shaping time. The outside of the plate heat exchange mechanism 9 is wrapped with a protective insulation layer 93 to prevent condensation.

[0024] The entire air cooling device is a complete circulation system. The various components cooperate with each other to achieve rapid cooling and molding. Through this systematic coordination, the air cooling device can improve production efficiency and improve the problems caused by traditional natural air cooling methods.

[0025] like Figure 2 As shown, the utility model provides a technical solution: the adjustment mechanism 2 includes a height adjustment rail 21, the top of the height adjustment rail 21 is plugged with an electric push rod 22, a base plate 23 is slidably connected to the height adjustment rail 21, the bottom of the electric push rod 22 is fixedly connected to the two ends of the base plate 23, the air cooler 8, the plate heat exchange mechanism 9, and the pressure tank 7 are installed on the top of the base plate 23, and the blow pipe 6 is installed at the bottom of the base plate 23.

[0026] The relevant air cooling devices are all arranged on the base plate 23, and the base plate 23 can be pushed up and down along the height adjustment rail 21 by the electric push rod 22. When the plastic barrel 3 passes through the fixing mechanism 5 and is transported to the bottom of the blow pipe 6 by the conveying mechanism 4, the adjustment mechanism 2 can lower the height of the relevant air cooling device and align the blow pipe 6 with the barrel mouth of the plastic barrel 3 to blow cold air to cool it down.

[0027] like Figure 5 , 2 As shown, the utility model provides a technical solution: the conveying mechanism 4 includes a track 41, a self-propelled walking block 42 is provided on the top of the track 41, a fixing mechanism 5 is fixedly installed on the top of the self-propelled block 42, and the fixing mechanism 5 includes a fixing plate 52, and a clamp 51 is provided on the inner wall of the fixing plate 52.

[0028] The clamp 51 is used to fix the newly produced plastic barrel 3 to be cooled, and then the plastic barrel 3 is transported to the bottom of the blow pipe 6 by the walking block 42 which moves on the track 41 by itself.

[0029] like Figure 4 As shown, the utility model provides a technical solution: a heat sink 91 is arranged inside the plate heat exchange mechanism 9, a cold air circulation duct 92 is opened inside the plate heat exchange mechanism 9 and on one side of the heat sink 91, and a natural circulation duct 95 is opened on the other side, a protective insulation layer 93 is arranged on the outer surface of the plate heat exchange mechanism 9, a fan 94 is connected to the right end of the plate heat exchange mechanism 9, and the left end of the plate heat exchange mechanism 9 is connected to the cold air fan 8.

[0030] The plate structure of the plate heat exchange mechanism 9 is composed of a large number of thin heat sinks 91 that are parallel to each other. The interior of the plate heat exchange mechanism 9 is composed of two air ducts, one is a cold air circulation duct 92 for cold air circulation, and the other is a natural circulation duct 95 for external natural air circulation. Closed circulation heat exchange is carried out in one of the air ducts, and the natural air after heat exchange enters in the other air duct in the reverse direction, passes through the heat sink 91, and exchanges heat with the cold air. The outside of the plate heat exchange mechanism 9 is wrapped with a protective insulation layer 93 to prevent condensation water.

[0031] The working principle of the air cooling device for plastic barrel molding is described in detail below.

[0032] like Figure 1-5 As shown, the air cooler 8 is a device for generating cold air. The refrigerant is repeatedly cooled by a refrigeration cycle through components such as a compressor, a condenser, an evaporator, and an expansion valve inside the air cooler 8, and the generated cold air is blown into the air duct of the plate heat exchange mechanism 9, and heat is exchanged with the natural wind flowing in the opposite direction of the air duct in the plate heat exchange mechanism 9. The air cooler 8 blows cold air into the plate heat exchange mechanism 9. The heat exchange between the two devices is a closed cycle, that is, the cold air source is flowing between the two devices. Another air duct in the plate heat exchange mechanism 9 is a natural circulation air duct 95. After heat exchange with the cold air source, the natural air after heat exchange is transferred from another air duct to the blow pipe 6 by the pressure tank 7, and the pressure tank 7 is a pressure vessel installed between the plate heat exchange mechanism 9 and the blow pipe 6. Under the specified pressure, the natural air after heat exchange is compressed and output from the other end for the blow pipe 6 to blow into the plastic barrel 3, and then blow cold air into the plastic barrel 3. The blow pipe 6 is one of the key components for air cooling and shaping of the plastic barrel 3. It is installed above the mouth of the plastic barrel and is responsible for blowing cold air into the plastic barrel 3, so that the hot plastic placed in it can be quickly cooled and solidified, which can greatly shorten the cooling and shaping time. The outside of the plate heat exchange mechanism 9 is wrapped with a protective insulation layer 93 to prevent condensation.

[0033] The entire air cooling device is a complete circulation system. The various components cooperate with each other to achieve rapid cooling and molding. Through this systematic coordination, the air cooling device can improve production efficiency and improve the problems caused by traditional natural air cooling methods.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
