[0002] Currently, various industries are increasingly using ton bagged materials. Traditional manual unpacking and feeding methods are no longer sufficient to meet the demands of efficient and dust-free production. Against this backdrop, fully enclosed ton bag unpacking machines have emerged, significantly improving material handling efficiency and providing businesses with an unprecedented dust-free ton bag unloading experience, leading a new trend in industry transformation. To accelerate unpacking speed, avoid dust pollution, and improve work efficiency, fully enclosed ton bag unpacking machines are used for rapid bag breaking. Utility Model Content

A negative pressure mechanism is located at the rear of the main body and is connected to the interior of the main body. A guide rail is located above the main body, and a trolley is slidably connected to the guide rail. An electric hoist is mounted on the trolley, and a ton bag hanger is suspended from the electric hoist. A bag-breaking mechanism is located inside the main body below the feed inlet. A perforated plate is located on the main body below the bag-breaking mechanism to intercept large pieces of material. Bag-tapping mechanisms are located on both sides of the main body above the bag-breaking mechanism, and support legs are located below the main body.

[0005] As a preferred technical solution of this utility model, the closing mechanism includes a closing cylinder, the rear end of which is hinged to the side of the main body, the output shaft of which is hinged to a connecting plate, the other end of which is connected to the sealing door, the connecting plate having an arc structure, and the sealing door being opened or closed by controlling the extension and retraction of the closing cylinder, with a sealing strip provided between the sealing door and the feed inlet.

[0006] As a preferred technical solution of this utility model, an air extraction hole is provided on the main body, and the negative pressure mechanism is connected to the interior of the main body through the air extraction hole, so that the negative pressure mechanism generates negative pressure inside the main body through the air extraction hole.

The cross-shaped bag breaking knife is also easy to replace if it is worn or damaged.

[0010] As a preferred technical solution of this utility model, the bag-tapping mechanism includes a bag-tapping cylinder, the output shaft of which extends into the interior of the main body, and a bag-tapping plate is provided on the output shaft of the bag-tapping cylinder. By activating the bag-tapping cylinder, the bag-tapping plate can tap the ton bag to prevent material residue inside the ton bag.

[0011] As a preferred technical solution of this utility model, an observation window is provided on the main body above the discharge port for observing whether too much material has accumulated on the perforated plate inside the main body.

[0012] As a preferred technical solution of this utility model, an avoidance groove is provided on the top of the main body, and a sealing strip is provided on the avoidance groove. The sealing strip is used to prevent dust inside the main body from flying out of the avoidance groove. The avoidance groove and the electric hoist are positioned correspondingly, so that the electric hoist can be moved into the interior of the main body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this utility model uses the cooperation of the guide rail, the track trolley and the electric hoist to bring the ton bag into contact with the cross-shaped bag-breaking knife, realizing fully automatic unpacking. During the material pouring process, the negative pressure mechanism creates a negative pressure in the inner cavity of the main body, which quickly sucks the released dust into the filter mechanism. After filtration, clean air is discharged, realizing truly dust-free unpacking. Attached Figure Description
