Description

Technical Field

[0001] This utility model relates to the field of unloading equipment, specifically to a bag-breaking device for bagged materials, and more particularly to a bag-breaking device that can actively break open ton bags or small bags of packaged materials under sealed conditions. Background Technology

[0002] In hydrometallurgical and mineral processing processes, it is often necessary to feed powdered or granular raw materials into leaching kettles, mixing tanks, and other equipment in ton bags (or large or small bags). Traditional manual bag-breaking methods are labor-intensive, inefficient, and generate significant dust, posing health risks to workers and causing chemical waste. Therefore, bag-breaking mechanisms are currently widely used. The mainstream bag-breaking mechanism is generally an open-type box-shaped mechanism that relies on the bag's own weight to fall onto fixed blades. However, this method has a low success rate, often resulting in bags that cannot be broken open or have only small openings. Therefore, there is an urgent need for a bag-breaking device with a high success rate and no dust generation. Utility Model Content

[0003] This utility model provides a bag-breaking device for bagged materials.

[0004] The specific technical solution is as follows: A bag-breaking device for bagged materials includes a sealed cavity. The sealed cavity has an openable and closable door at the top and a hopper at the bottom. Support beams are installed between the inner walls on both sides. A liftable bag-breaking mechanism is installed above the support beams. The bag-breaking mechanism includes a high-power electric push rod installed above the support beams. The telescopic end of the high-power electric push rod is connected to the center of a cross-shaped cutter bracket. A central fixing rod is connected to the center of the top of the cross-shaped cutter bracket. The top of the central fixing rod is a spike. Cutters are connected between the central fixing rod and the four distal ends of the cross-shaped cutter bracket. The four distal ends of the cross-shaped cutter bracket are slidably connected to sliding rods installed on the inner wall of the sealed cavity through linear bearings. The sliding rods are arranged along the height direction of the sealed cavity.

[0005] Furthermore, preferably, the compartment door is a double door, and at least two sets of low-power electric push rods are provided on the outer sides of the two compartment doors to control the opening and closing of the compartment doors.

[0006] Furthermore, preferably, a steel rope through hole is provided at the center of the closed two doors for the material bag hoisting rope to pass through.

[0007] Furthermore, preferably, a reinforcing rod is connected between the cutting tool and the central fixing rod to enhance the strength of the cutting tool.

[0008] The beneficial effects of this utility model are as follows: This device integrates four major functions—bag breaking, sealing, pressing, and unloading—into one cavity through a simple vertical lifting structure of "electric push rod-slide rod-cutter bracket." The high-power electric push rod directly drives the cross-shaped cutter bracket in the center, and the four linear bearings at the four ends precisely guide the cutter along the slide rod, ensuring stable vertical trajectory of the cutter and concentrated bag breaking force. The split-type compartment door is opened and closed synchronously by a low-power electric push rod. After the door is closed, it can press the bag in the opposite direction, forming a self-clamping effect to prevent the bag from moving upward with the cutter. The spike at the top of the central fixing rod first pierces and then centers the bag, and the cutter reinforcing rod synchronously increases the rigidity, so that bag breaking is completed in one go. The overall structure does not require an additional bag clamping mechanism, thus achieving highly reliable bag breaking, high-sealing dust prevention, compatibility with different packaging bag specifications, high-efficiency unloading, and low-maintenance operation.

[0012] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0013] like Figure 1-3 As shown, a bag-breaking device for packaged materials includes a sealed cavity 3. The sealed cavity 3 has an openable and closable door 1 at the top and a feeding hopper 7 at the bottom. Support beams 6 are installed between the inner walls on both sides. A lifting bag-breaking mechanism is installed above the support beams 6. This bag-breaking mechanism includes a high-power electric push rod 13 installed above the support beams 6. The telescopic end of the high-power electric push rod 13 is connected to the center of a cross-cutter bracket 12. A central fixing rod 10 is connected to the center of the top of the cross-cutter bracket 12. The top of the central fixing rod 10 is a spike 9. Cutters 4 are connected between the central fixing rod 10 and the four distal ends of the cross-cutter bracket 12. The four distal ends of the cross-cutter bracket 12 are slidably connected to sliding rods 5 installed on the inner wall of the sealed cavity 3 via linear bearings 14. The sliding rods 5 are arranged along the height direction of the sealed cavity 3. The high-power electric push rod 13 can drive the bag-breaking mechanism to move vertically up and down along the sliding rods 5.

[0014] Furthermore, the storage door 1 is a double door, and at least two sets of low-power electric push rods 2 are provided on the outer sides of the two storage doors 1 to control the opening and closing of the storage doors; the low-power electric push rods 2 are all installed on the receiving plate 15 on the outer side of the sealed cavity 3.

[0015] Furthermore, a steel rope through hole 8 is provided at the center of the closed position of the two warehouse doors 1 for the material bag hoisting rope to pass through.

[0016] Furthermore, a reinforcing rod 11 is connected between the cutting tool 4 and the central fixing rod 10 to enhance the rigidity of the cutting tool 4 and prevent deformation.

[0017] Furthermore, it should be noted that a sealing strip can be added between the hopper door 1 and the sealed cavity 3, and an elastic dust cover can be installed at the steel rope through hole 8 to improve the overall airtightness of the device and prevent material dust from escaping. The height of the slide bar 5 should be set as high as possible to ensure that the cutter 4 has sufficient upward space to accommodate material bags of different sizes. Both the high-power electric push rod 13 and the low-power electric push rod 2 can be connected to the control unit to achieve automatic control.

[0018] Working Principle: During operation, the overhead crane lifts the ton bag (or small bag) directly above the sealed cavity 3. The bottom of the bag is first pierced by the spike 9 at the top of the central fixing rod 10, forming an initial position. The low-power electric push rods 2 on both sides of the two doors 1 are activated, extending synchronously and pushing the double-leaf doors 1 to close. At this time, the elastic dust cover inside the steel rope through-hole 8 automatically wraps around the lifting rope, forming a completely sealed space in the sealed cavity 3, blocking the escape path of dust. Then, the high-power electric push rod 13 is activated, its telescopic end pushing the cross-blade support 12 to rise vertically along the four sliding rods. The central fixing rod 10 continues to penetrate deep into the bag, acting as a "centering" element. The blades 4 connected to the four ends of the support forcefully cut open the bag from bottom to top during the upward movement. Simultaneously, the doors 1 exert a reverse pressure on the bag, preventing the bag from moving upward with the blades and ensuring the cut is fully opened.

[0019] The upward stroke of the cross-shaped cutter support 12 can be flexibly set according to the bag specifications. When it rises to the set upper limit, it automatically descends, and the cutter 4 resets. At this time, the bag has been completely longitudinally cut open, and the material falls into the leaching tank or mixing tank below through the hopper 7 under the action of gravity. After unloading, the low-power electric push rod 2 is controlled to retract, the hopper door 1 is opened, and the trolley removes the empty bag, completing a fully automatic closed cycle of "lifting the bag - closing the door - breaking the bag - unloading - opening the door - moving the bag".

[0020] After testing on ton bags containing gold concentrate cyanide and 25kg small bags, the device was found to be able to make a longitudinal cut of ≥80cm in length at the bottom of the ton bag, complete the unloading of the small bag within 20s, and prevent dust from escaping during the entire process.

[0021] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
