Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment technology, and in particular to vacuum suction cup lifting and hoisting equipment. Background Technology

[0002] In modern industrial production, vacuum suction cups are widely used as efficient and economical lifting tools for handling and positioning various materials. The vacuum suction cups of these lifting tools rely on creating a vacuum environment inside to attract and lift objects. However, some problems exist in practical applications.

[0003] First, when the vacuum suction cup of a vacuum lifting device sucks in impurities such as dust, debris, or liquid, these impurities block the airflow, reducing suction power and affecting its normal operation. These impurities, once sucked into the extraction device, can even damage it. Furthermore, the presence of impurities can cause instability in the suction cup during the adsorption process, increasing operational risks.

[0004] To address these issues, although some improvements have been made to the market, such as the use of filters, these are very troublesome to clean and inefficient. Utility Model Content

[0012] An anti-clogging air guiding mechanism includes: an upper side surface in contact with the central area; the upper side surface extending away from the rigid disc to form a lower side surface opposite to the upper side surface; and a surrounding air guiding surface extending between the upper and lower sides surface.

[0015] The vacuum suction cup lifting device provided by this utility model preferably has a mounting plane in the central area of ​​the second side. The mounting plane contacts and nests the upper side of the anti-blocking air guiding mechanism. The second side is provided with an upward pull plane corresponding to the mounting plane.

The anti-clogging air guiding mechanism can change the angle of gas extraction, transforming vertical extraction into horizontal extraction, reducing the suction force on impurities at the bottom in the vertical direction, thus making them less likely to be sucked out. Furthermore, multiple smaller inner diameter first air guiding channels replace the commonly used single larger inner diameter suction hole, preventing larger impurities from being sucked out and causing severe blockage. A movable filter screen is also provided to block smaller impurities and protect the extraction device. Simultaneously, the anti-clogging air guiding mechanism is detachable, ensuring efficient dust removal. Attached Figure Description
