Description

Technical Field

[0001] The utility model relates to the technical field of ton bag unpacking, in particular to a ton bag unloading station. Background Art

[0002] Ton bags, also known as flexible container bags, are a type of flexible transport packaging container. Equipped with cranes or forklifts, centralized unitized transportation of chemical raw materials, pharmaceutical raw materials, food additives, feed additives and other materials can be achieved. The unloading process of ton bags is achieved through ton bag unpacking machines. At present, the frame of the existing ton bag unpacking machine adopts a truss-type double-layer structure. The upper part of the machine frame is the driving part, and the driving part mostly uses electric hoists, which requires a large operating space to be reserved. The lower part of the frame is the ton bag and the discharge part, and the total height of the machine frame reaches 5-6m. Therefore, the vertical installation space of the existing ton bag unpacking machine is relatively high. For some old-style factories with low lifting frames, this type of ton bag unpacking machine cannot be used. In addition, the existing ton bag unpacking machine uses a cross hanger to hang the ton bag, and cooperates with the electric hoist to realize the lifting operation of the ton bag. Due to the poor connection stability between the cross hanger and the hook of the electric hoist, the ton bag is prone to the problem of center of gravity shift during the lifting process, which increases the risk of the ton bag detaching from the hook.

[0003] In summary, the existing ton bag unpacking machines have problems such as the body frame being too high, occupying a large vertical space, and the ton bag having poor stability and being easy to fall off during the lifting operation. Utility Model Content

The cylinder body of the balancing drive cylinder 91 is hinged to the fixed frame 1 through the balancing hinge 2 93. In this arrangement, since the flipping drive mechanism 3 is located on one side of the movable frame 2, when the rotating shaft of the flipping drive motor 31 drives the worm structure of the worm gear pair 32 to rotate through a pair of bevel gear pairs, the worm structure is meshed with the turbine structure, and the movable frame 2 is driven to flip around the flip axis, it is easy to cause the machine body to twist, which may cause damage to the machine body. Therefore, the balancing drive mechanism 9 is arranged on the other side of the flipping drive mechanism 3, and the piston rod of the balancing drive cylinder 91 is extended and retracted with the flipping action of the movable frame 2, thereby preventing the machine body from twisting. The other components and connection relationships are the same as those of the first, second, third, fourth, fifth, sixth, seventh, eighth or ninth embodiment.

[0042] How it works

[0043] Combination Figures 1 to 11 Explain the working principle of the ton bag unloading station of the utility model:

[0044] First, the flipping drive motor 31 is started, and the worm gear pair 32 drives the movable frame 2 to flip downward to a horizontal state with the flipping axis as the center. During this process, the bidirectional cylinder 51 is started, and the supporting shaft 41 of the ton bag hanging assembly 4 is pushed to the front end of the movable frame 2 as the movable frame 2 flips, so that the ton bag 10 can be hung on the hanging ear 45.

[0045] Then, the flipping drive motor 31 is started, and the movable frame 2 is driven to flip upward to a vertical state with the flipping axis as the center through the worm gear pair 32, and the bidirectional cylinder 51 is started to adjust the height of the support shaft 41 so that the bag opening of the ton bag 10 and the bottom discharge port are at a suitable distance, the bag opening is opened, and unloading begins to ensure that the material can smoothly flow into the external receiving container through the discharge port;

[0046] As the material in the ton bag 10 gradually decreases, the shape of the ton bag 10 also becomes longer, and the two-way cylinder 51 is started again to continuously adjust the distance between the bag opening of the ton bag 10 and the bottom discharge opening, and at the same time, the bag-beating driving cylinder 71 is started, so that the support plate 61 repeatedly beats the lower parts of both sides of the ton bag 10 until the material in the ton bag 10 is emptied;

[0047] Finally, when the unloading is completed, the two-way cylinder 51 is started, and the emptied ton bag 10 is lifted to the head end of the movable frame 2 again, and the flipping drive motor 31 is started, and the movable frame 2 is driven by the worm gear pair 32 to flip downward to a horizontal state with the flip axis as the center, and the emptied ton bag 10 is replaced, and then the next round of unloading is carried out.
