This machine is suitable for cleaning plastic cases in beer and beverage bottling production lines. It consists of three main parts: the case washer, the case turnover mechanism, and the case uprighting mechanism. High-pressure hot water is used to clean the cases from all directions, ensuring they are thoroughly clean. The machine has a compact structure, is easy to operate, and is simple to maintain.

This machine mainly uses a water pump to draw heated water from the water tank at high speed into the spray pipes, and then sprays it out through the nozzles installed on the spray pipes, forming high-pressure water jets that spray onto the returnable cases. The high-pressure, high-temperature water washes away dirt from the surfaces of the returnable cases. During the washing process, various cleaning solvents can also be added to improve the cleaning effect.

Washing chamber
a) The washing chamber is installed between the forward and reverse case turnover devices. It mainly consists of the main body, guide frames, case conveying device, spraying system, heating device, and other major components.
b) The main body is a stainless steel box-type structure, with the water tank in the lower part and the main transmission and spraying devices installed in the upper part.
c) The main transmission is driven by a reducer to move the flat-top chain for conveying. When cases enter the case washer from the turnover device, they are guided by the guide frames. Hot water spraying consists of 7 groups of spray pipes with a total of 63 nozzles. The 7 groups are divided into 2 groups on each side, 1 group on the top, and 2 groups on the bottom. Hot water is drawn from the water tank by the hot water pump and sent to the hot water spray main pipe, then distributed to the 7 groups of spray pipes to clean the cases comprehensively from four directions at different angles, followed by clean water spraying.
d) Clean water spraying consists of 1 group of spray pipes with a total of 18 nozzles, divided into 4 groups on each side, 5 groups on the top, and 5 groups on the bottom. Clean water is supplied from the clean water inlet pipe to the clean water spray main pipe, and sprayed from the four directions onto the cases at different angles.
e) The heating device is installed in the water tank inside the main body. It mainly consists of a steam inlet pipe, a direct heater, a thermometer, and other major components. Steam is fed into the direct heater to heat the water in the tank.

Case turnover device
a) The case turnover device consists of two sets of turnover mechanisms for input and output, installed at the case inlet and outlet sections of the case washer respectively. It mainly consists of a frame, guide rods, a debris trough, and other major components. (The two turnover mechanisms are basically the same, but the output turnover device does not have a debris trough.)
b) The frame is made of steel profiles, with the turnover guide rod mechanism installed on the upper part and the debris trough installed on the lower part.
c) The guide rod mechanism consists of outer guide rods, side guide rods, curved plates, etc. Cases are conveyed from the case conveyor and pass through the turnover guide rod mechanism, which turns the cases over. (This movement is driven by the power from the case conveyor.)
d) Since dirty plastic cases may contain debris, during the turnover process, debris falls into the debris trough and then flows into a debris container.
This machine does not come with a debris container; it is to be provided by the user.
