Packaging device for covering and sealing cover film onto tray
InactiveUS20060123739A1Avoid sealing difficultiesWrappers shrinkageWrapper twisting/gatheringFlangeEngineering
A packaging device is provided which prevents trays accommodating packaged items from being broken due to the tension in a film acting from above. The sealing base and the sealer perform a box motion by the combination of the back and forth movement of the general frame, and the upward and downward movement of the sealing base and the sealer, and the film is welded onto the flange of the tray while in movement. In this case, by setting the upper limit of the sealing base to the lower surface of the flange of the tray, it is possible for the deck plate to receive the tension of the film acting on the tray through the packaged item.

The invention discloses a washing powder dissolving device. The washing powder dissolving device comprises a box body, a guiding pipe and a stirrer. A water inlet used for leading washing water into the box body is formed in the right side of the box body, and a water inflow electromagnetic valve is installed on the outer side of the water inlet. A water outlet used for discharging the washing water in the box body is formed in the bottom of the box body, and a water outflow electromagnetic valve is installed on the outer side of the water outlet. The guiding pipe is detachably and fixedly arranged in the box body and composed of a vertical segment, an elbow segment and a horizontal segment, and the vertical segment and the horizontal segment are connected through the elbow segment. The stirrer comprises a motor and a stirring impeller, the motor is fixedly installed above the outer side of the box body, and the lower end of a motor output shaft penetrates into the box body through a shaft hole formed in the upper portion of the box body and is inserted into the vertical segment of the guiding pipe. The stirring impeller is fixed to the lower end of the motor output shaft. A liquid level sensor is further arranged on the inner side of the box body. The washing powder dissolving device can fully use the idle space of a washing machine, and therefore washing powder can be fully dissolved.
