Description

Technical Field

[0001] This utility model relates to the field of fabric equipment technology, specifically to a bag-breaking crane. Background Technology

[0002] Efficient material handling and warehousing management are crucial for controlling operational costs and improving production efficiency for businesses. Especially when dealing with large quantities of powdery, granular, or lumpy materials, ton bag packaging is widely used due to its large capacity and ease of handling. However, traditional material handling and warehousing processes have many problems. For example, the process of removing materials from ton bags and distributing them to different hoppers often requires a significant amount of manual labor, including manually moving the ton bags, manually breaking them open, and transferring the materials one by one to the corresponding hopper. This process not only consumes a lot of manpower and time, but also easily leads to material leakage and waste during manual bag breaking, while increasing labor intensity and reducing work efficiency.

[0003] Currently, some bag-breaking devices exist on the market, but their functions are relatively limited. Most can only break bags and cannot form an efficient integrated process with the lifting of bulk bags and the distribution of materials. For example, some bag-breaking devices require the bulk bags to be moved to a specific location for breaking, and the broken materials still need to be transferred and distributed again by other equipment. This undoubtedly increases the intermediate links in material handling, leading to a significant increase in the time and cost of material handling and warehousing. At the same time, some existing cranes are mainly used for lifting and moving heavy objects and lack the ability to coordinate with bag-breaking and material distribution operations, failing to meet the needs of enterprises for rapid and efficient material transfer.

[0004] Therefore, developing a device that integrates ton bag gripping, bag breaking, and material distribution operations is of significant practical importance. By combining a bag-breaking box with a crane, one-stop processing of ton bags can be achieved, reducing the time and costs associated with material transfer and storage, and improving material handling efficiency—a problem urgently needing to be solved in current industrial production. This patent aims to provide an innovative bag-breaking crane to effectively address the shortcomings of existing technologies and meet the demands of modern industrial production for efficient and low-cost material handling. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a bag-breaking crane that combines a bag-breaking box with a crane to perform operations such as grabbing, breaking, and distributing materials from ton bags. The bag-breaking box is equipped with a lifting device to lift the ton bags, and then, in conjunction with a feeding module, distributes the materials inside the ton bags into different feeding hoppers, reducing the time and cost of material transfer and storage, and improving the efficiency of material transfer.

[0006] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a bag-breaking crane, including a receiving bin, a bridge frame above the receiving bin, a traveling trolley on the bridge frame, a bag-breaking box on the traveling trolley, a lifting device on the upper part of the bag-breaking box, and a bag-breaking unloading module below the bag-breaking box. The lifting device includes a cantilever beam and a hook. A movable seat for driving the hook to make lateral displacement is provided on the cantilever beam, and a winch connected to the hook is provided on the movable seat.

[0007] As a further improvement to the above technical solution:

[0008] The cantilever beams and bridges are vertically distributed, and a sealing door located at the end of the cantilever beam is provided on the side wall of the bag-breaking box.

[0009] The number of sealing doors is two and they are symmetrically distributed about the center line of the bag-breaking box. Opening and closing cylinders connected to the two sealing doors are provided on both sides of the bag-breaking box.

[0010] The feeding module includes a feeding hopper, and a bag-breaking knife assembly is provided on the upper part of the feeding hopper.

[0011] The bag-breaking knife assembly includes a conical cutter head located at the center of the hopper, and the lower part of the conical cutter head is provided with supporting ribs that connect to the inner wall of the hopper.

[0012] The number of supporting ribs is multiple and they are evenly distributed along the circumference of the conical cutter head. Each supporting rib is provided with a cutting blade on its upper part.

[0013] The conical cutter head is located above the hopper, and the supporting ribs are inclined and gradually decrease in height from the end connected to the conical cutter head outward.

[0014] A telescopic pipe is provided between the feeding hopper and the bag breaking box, and a guide device is provided on the outside of the telescopic pipe.

[0015] The guiding device includes a guide rod, the lower end of which is fixedly connected to the hopper and the upper part is slidably connected to the bag-breaking box.

[0016] The beneficial effects of this utility model embodiment are as follows: The bag breaking crane includes a receiving bin, a bridge frame is provided above the receiving bin, a traveling trolley is provided on the bridge frame, a bag breaking box is provided on the traveling trolley, and a lifting device is provided on the upper part of the bag breaking box. The bridge frame and the lifting device can drive the ton bag to move in the X, Y, and Z axes, thereby completing the material transfer and laying operation. Compared with the conventional transfer and laying method, the laying operation can be completed directly during the lifting of materials, reducing the time and cost occupied by materials in transfer and storage, and improving the efficiency of material transfer.

[0017] The lifting device includes a cantilever beam and a hook. The cantilever beam is equipped with a movable seat for driving the hook to move laterally. The movable seat is equipped with a winch connected to the hook. The hook can be used to complete the operation of loading and unloading ton bags into and out of the bag-breaking box, reducing manual intervention, improving work efficiency and reducing labor costs.

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] like Figure 1-5As shown, the bag-breaking crane of this embodiment includes multiple receiving bins 1 distributed in different locations. A bridge frame 2 is provided above the receiving bins 1. Traveling wheels are installed at both ends of the bridge frame 2, and a track is laid below the traveling wheels. A traveling trolley 3 is installed on the bridge frame 2, and a bag-breaking box 4 is provided on the traveling trolley 3. A lifting device is installed on the upper part of the bag-breaking box 4, and a bag-breaking unloading module is provided below the bag-breaking box 4. The lifting device includes a cantilever beam 5 and a hook 6. A movable seat 7 is installed on the cantilever beam 5 for driving the hook 6 to make lateral displacement. The movable seat 7 drives the hook 6 along the length of the cantilever beam 5. The moving base 7 is equipped with a winch 8 connected to the hook 6 to move the ton bag into and out of the bag-breaking box 4. The winch 8 can change the height of the hook 6 to lift and lower the ton bag. The displacement of the bridge frame 2, the traveling trolley 3 and the hook 6 drives the ton bag to move in the X, Y and Z axes to complete the material transfer and laying operation. Compared with the conventional transfer and laying method, the laying operation can be completed directly during the lifting of materials, reducing the time and cost of material transfer and storage and improving the efficiency of material transfer.

[0026] The cantilever beam 5 and the cable tray 2 are vertically distributed. The side wall of the bag breaking box 4 is provided with a sealing door 9 located at the end of the cantilever beam 5. There are two sealing doors 9, which are symmetrically distributed with the center line of the bag breaking box 4 as the axis. On both sides of the bag breaking box 4, there are opening and closing cylinders 10 that are connected to the two sealing doors 9 respectively. The upper part of the two sealing doors 9 is reserved with a clearance notch corresponding to the position of the cantilever beam 5.

[0027] The feeding module includes a feeding hopper 11, and a bag-breaking knife assembly is provided on the upper part of the feeding hopper 11. The bag-breaking knife assembly includes a conical cutter head 12 located at the center of the feeding hopper 11. The lower part of the conical cutter head 12 is provided with a supporting rib 13 connected to the inner wall of the feeding hopper 11. The design of the conical cutter head 12 allows for opening at the bottom of the ton bag.

[0028] There are multiple supporting ribs 13, which are evenly distributed along the circumference of the conical cutter head 12. Each supporting rib 13 is equipped with a cutting blade 14 on its upper part. As the ton bag continues to fall, the cutting blade 14 can expand the opening area based on the central opening, further improving the feeding speed.

[0029] The conical cutter head 12 is located above the hopper 11. The supporting ribs 13 are installed at an angle and extend outward from the end connected to the conical cutter head 12, with the height gradually decreasing. The supporting ribs 13 are arc-shaped, which can facilitate the cutting blades 14 to cut open the ton bag during the ton bag's descent.

[0030] A telescopic pipe 15 is provided between the feeding hopper 11 and the bag-breaking box 4. A guide device is provided on the outside of the telescopic pipe 15. The guide device includes a guide rod 16. The lower end of the guide rod 16 is fixedly connected to the feeding hopper 11, and the upper part is slidably connected to the bag-breaking box 4. There are multiple guide rods 16, which are evenly distributed along the circumference of the bag-breaking box 4. The bottom of the feeding hopper 11 is provided with a discharge pipe that connects to the receiving bin 1. When feeding, after the discharge pipe connects with the receiving bin 1, in order to increase the tightness of the connection, the feeding hopper 11 will be pressed down under the action of the material's gravity. During this process, the telescopic pipe 15 will extend. After the material is unloaded, the gravity disappears, and the telescopic pipe 15 springs back to its original position. The guide rod 16 can prevent the feeding hopper 11 from tilting during the extension and retraction process, ensuring that the bag-breaking box 4, the telescopic pipe 15, and the feeding hopper 11 always remain coaxial.
