Description

Technical Field

[0001] This utility model belongs to the technical field of bulk material loading and unloading equipment, specifically, it relates to a new type of bag-cutting device based on traditional transshipment equipment. Background Technology

[0002] In the bulk cargo handling sector, ton bags (also known as flexible containers) are a common packaging form for bulk materials and are widely used in industries such as grain, chemicals, and mining. Traditional ton bag unloading mainly relies on manual bag breaking or fixed bag breaking devices. When manually breaking bags with knives, workers need to be in close contact with the ton bags, posing safety hazards such as knife cuts and material splashing (such as dust and corrosive substances). At the same time, manual bag breaking is inefficient and cannot meet the high throughput requirements of modern logistics. Existing mechanical bag breaking devices mostly use fixed-gap knife arrays, which cannot be adapted to the stitching spacing of different ton bag sizes. Frequent knife changes or equipment adjustments are required during operation, leading to reduced efficiency. In addition to the above problems, there are also issues such as insufficient positioning accuracy, high maintenance costs, and low integration with transshipment equipment. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a novel bag-cutting device based on traditional transshipment equipment, comprising a transshipment belt conveyor and a hopper, wherein the hopper is fixed above the transshipment belt conveyor, and further comprising: A gantry frame is fixed to the transshipment belt conveyor, with the upper end of the gantry frame extending beyond the upper end of the hopper; Two bag-splitting rods are fixed above the gantry; Multiple slicing blades are evenly distributed on the slicing frame rod; Multiple adjustment mechanisms, each corresponding to a slicing blade tip, are mounted on the slicing frame rod. These adjustment mechanisms connect the slicing blade tips to the slicing frame rod and allow adjustment of the distance between adjacent slicing blade tips. A ton bag positioning frame is fixed above the bag-splitting frame rod and is used to position the ton bags.

[0004] As a preferred embodiment, the adjustment mechanism includes: Multiple cutter holders, each of the bag-slicing cutter tips is fixedly connected to a separate cutter holder, and the lower surface of the cutter holder is in sliding contact with the bag-slicing frame rod; A sliding frame is fixed below the cutter holder, and the sliding frame and the cutting frame rod can slide relative to each other, used to move or fix the cutter holder.

[0005] As a preferred embodiment, there are two sliding frames below each of the cutter holders, which are symmetrically arranged about the cutting frame rod. The two sliding frames are connected by screws and nuts. By tightening or loosening the screws and nuts, the sliding frames are controlled to clamp the cutting frame rod, thereby controlling whether the sliding frames are in a fixed or sliding state.

[0006] As a preferred embodiment, each of the tool holders has a guide groove at its lower end that is slidably connected to the slitting frame rod.

[0007] As a preferred embodiment, the gantry, the bag-cutting frame rod, the bag-cutting knife tip, and the ton bag positioning frame are all made of 304 stainless steel.

[0008] As a preferred embodiment, the slicing blade tip is composed of four independent blades welded together.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This application achieves a comprehensive improvement in safety, efficiency, and cost reduction through fully automated human-machine isolation operation, a stepless adjustable tooling system, and a modular quick-release design; combined with corrosion-resistant materials, it simultaneously addresses the pain points of dust pollution and high maintenance, providing the bulk material industry with a safe, efficient, environmentally friendly, and energy-saving solution for breaking up packages.

[0011] The present invention will be further described below with reference to specific embodiments.

[0012] A novel bag-cutting device based on traditional transshipment equipment includes a transshipment belt conveyor 1 and a hopper 2, the hopper 2 being fixed above the transshipment belt conveyor 1, and further includes: The gantry 3 is fixed on the transshipment belt conveyor 1, and the upper end of the gantry 3 extends beyond the upper end of the hopper 2; Two bag-splitting rods 4 are fixed above the gantry 3; Multiple slicing blade tips 5 are evenly distributed on the slicing frame rod 4; Multiple adjustment mechanisms corresponding one-to-one with the slicing knife tip 5 are set on the slicing frame rod 4. The adjustment mechanisms connect the slicing knife tip 5 to the slicing frame rod 4 and can adjust the distance between adjacent slicing knife tips 5. The ton bag positioning frame 6 is fixed above the bag rack rod 4 and is used to position the ton bag.

[0013] The height design of the gantry 3 ensures that the bottom of the ton bag is aligned with the inlet of hopper 2 when it is suspended, preventing materials from scattering. The gantry 3 serves as the main support structure, and the ton bag positioning frame 6 can adopt a U-shaped slot structure to achieve rapid positioning of the ton bag lifting lugs through gravity self-locking. The spacing of the blade tip 5 can be adjusted to match different ton bag stitching positions, ensuring that the force is even when the ton bag is cut open.

[0014] As a preferred option, the regulating mechanism includes: Multiple cutter holders 7, each cutter tip 5 is fixedly connected to a separate cutter holder 7, and the lower surface of the cutter holder 7 is in sliding contact with the cutter frame rod 4; The sliding frame 8 is fixed below the cutter holder 7. The sliding frame 8 and the cutting frame rod 4 can slide relative to each other and are used to move or fix the cutter holder 7.

[0015] As a preferred embodiment, there are two sliding frames 8 below each cutter holder 7, which are symmetrically arranged about the cutting frame rod 4. The two sliding frames 8 are connected by screws and nuts. By tightening or loosening the screws and nuts, the sliding frames 8 can be controlled to clamp the cutting frame rod 4, thereby controlling whether the sliding frames 8 are in a fixed or sliding state.

[0016] When it is necessary to adjust the position of the slicing knife tip 5, loosen the nut, the friction between the sliding frame 8 and the slicing frame rod 4 is released, and the knife holder 7 can slide freely, thereby adjusting the position of the slicing knife tip 5; When it is necessary to fix the slicing tip 5, tighten the nut, the sliding frame 8 clamps the slicing frame rod 4, and the position is locked by the friction between the screw and the sliding frame 8 and the slicing frame rod 4. The symmetrical clamping design of the sliding frame 8 can effectively avoid the problem of excessive stress concentration on one side of the slicing frame rod 4, and the position of the slicing blade tip 5 can be quickly adjusted without disassembling the blade.

[0017] As a preferred embodiment, each cutter holder 7 has a guide groove at its lower end that is slidably connected to the slicing frame rod 4. The guide groove can prevent the slicing blade tip 5 from deviating, which would cause the slicing trajectory to deviate.

[0018] As a preferred option, the gantry 3, the bag-cutting frame rod 4, the bag-cutting knife tip 5, and the ton bag positioning frame 6 are all made of 304 stainless steel. 304 stainless steel has good corrosion resistance and structural strength, and can adapt to high humidity and salt spray environments such as ports and chemical plants. At the same time, it has high yield strength and can meet the impact load of ton bags.

[0019] As a preferred option, the slicing blade tip 5 is composed of four independent blades welded together. The multi-edge design forms a "progressive cutting" effect, reducing instantaneous cutting resistance. Furthermore, the blades can be replaced individually, reducing maintenance costs.

[0020] The complete workflow for the above content is as follows: Ton bag positioning: Lift the ton bag by inserting the lifting lug into the positioning frame 6 slot, and let the bottom of the ton bag hang down naturally above the inlet of hopper 2.

[0021] Tool spacing adjustment: According to the markings on the ton bag's stitching line, loosen the nut corresponding to the knife holder 7, slide the knife holder 7 to the target position, and then lock it.

[0022] Package cutting task: Start the transfer conveyor belt 1. The ton bag moves down with the vibration of the conveyor belt 1. The blade tip 5 contacts the bottom of the bag and cuts it open along the seam line.

[0023] Material unloading: After the bag is broken, the material falls into hopper 2 and is conveyed to the target area by belt conveyor 1. The empty bag is removed by hoisting equipment.

[0024] Reset maintenance: Clean the blade tip 5 of any remaining material, check the clamping force of the sliding frame 8, and replace the worn blade if necessary.

[0025] This utility model features a dual anti-drop design with mechanical locking and dynamic monitoring, while also adaptively adjusting the load to extend the life of the idler rollers and prevent them from falling off due to prolonged wear, thus maximizing the protection of the belt and reducing economic losses.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art, and their specifications and models can be selected according to actual conditions.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
