Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, and in particular to a simple airbag baling machine suitable for ton bags of different specifications. Background Technology

[0002] A dust baler is a mechanical device specifically designed for processing and packaging various powdery, granular, or small lump materials. It is widely used in industries such as chemical, food, pharmaceutical, building materials, and mining, primarily for efficiently and safely filling these materials into ton bags, paper bags, plastic bags, or other containers. The main functions of a dust baler include material conveying, weighing, filling, sealing, and dust removal to ensure hygiene, environmental protection, and operator safety during the production process.

[0003] Currently, most of the baling machines available in the powder conveying industry are high-precision baling machines with built-in metering systems. Their main drawbacks are:

[0004] 1. For applications that do not require high precision, the cost is high and the functions are excessive;

[0005] 2. Applicable only to one size of ton bag;

[0006] 3. Height is not adjustable;

[0007] 4. Most ton bag clamping mechanisms use long-arm or urethane rubber structures, which are prone to powder leakage after prolonged use and require frequent maintenance.

[0008] In a packaging environment with moderate production, excessive functionality can lead to increased costs. Furthermore, the applicability of a single-size ton bag cannot meet the diverse production needs. When in use, its structure needs to be further processed and improved, which increases the number of processes and reduces work efficiency. To address this, the inventor has proposed a simple airbag-type baling machine suitable for ton bags of different sizes to solve the aforementioned technical problems. Utility Model Content

[0009] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0010] A simple airbag-type baler suitable for ton bags of different sizes includes support legs, a moving platform, a feeding dust hood, and a height adjustment structure. The support legs are used to fix the moving platform. The feeding dust hood is installed on the surface of the moving platform. One end of the feeding dust hood is connected to a bag clamping structure. One end of the bag clamping structure is used to connect an external ton bag. The bag clamping structure includes a bag clamping cylinder, an inflatable airbag, and an airbag fixing ring seat. The surface of the moving platform is equipped with a hook structure for limiting the position of the external ton bag. The hook structure includes a hook cylinder, a hook fixing seat, a hook, and an anti-drop baffle.

[0011] Furthermore, the bag clamping cylinder is installed on the surface of the airbag fixing ring seat, the interior of the airbag fixing ring seat is a hollow structure, and the inflatable airbag is located inside the airbag fixing ring seat.

[0012] Furthermore, the hook cylinder is located on the surface of the hook fixing seat, and one end of the hook cylinder abuts against the surface of the hook. The hook cylinder is used to push the hook or limit the position of the hook. The hook is limited to the inside of the hook fixing seat by the stop shaft. The anti-drop baffle is rotatably limited to the inside of the hook fixing seat. The anti-drop baffle can only rotate inward and cannot rotate outward, which plays a role in preventing the ton bag strap from falling off.

[0013] Furthermore, the height adjustment structure includes a connecting sleeve and a positioning pin. The surfaces of both the support leg and the connecting sleeve are provided with pin holes for connection with the positioning pin. The connecting sleeve is installed on the surface of the support leg by locking screws and nuts. The positioning pin and the support leg are detachable.

[0014] Furthermore, the surface of the feed dust hood is provided with an exhaust filter, one end of which extends into the interior of the feed dust hood.

[0015] Furthermore, a weighbridge is placed below the ton bag, and the weighbridge and the ton bag are separate structures.

[0016] Furthermore, one end of the hook fixing seat is connected to a baffle that limits the range of motion of the hook, and the baffle and the hook fixing seat are integrally formed.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This simple baling machine does not have a built-in metering system. It uses a low-cost metering structure such as a weighbridge to achieve the metering function. The separate structure reduces vibration caused during operation, thus reducing weighing errors.

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] For this embodiment, please refer to Figures 1-13The present invention relates to a simple airbag baling machine applicable to ton bags of different specifications, comprising support legs 3, a moving platform 5, a feeding dust hood 6, and a height adjustment structure. The support legs 3 are used to fix the moving platform 5. The feeding dust hood 6 is installed on the surface of the moving platform 5. One end of the feeding dust hood 6 is connected to a bag clamping structure 8. One end of the bag clamping structure 8 is used to connect to an external ton bag 2. The bag clamping structure 8 includes a bag clamping cylinder 19, an inflatable airbag 20, and an airbag fixing ring seat 21. The surface of the moving platform 5 is equipped with a hook structure 9 for limiting the position of the external ton bag 2. The hook structure 9 includes a hook cylinder 13, a hook fixing seat 16, a hook 15, and an anti-drop baffle 14.

[0039] This structure improves the ease of operation by introducing an inflatable airbag 20 to clamp the ton bag 2. Combined with the hook structure 9 and the dust cover 6 and height adjustment device, it not only enhances the automation level and safety of the equipment, but also strengthens its adaptability to ton bags of different sizes. Compared with traditional packaging equipment, this structure has improved in terms of ease of operation, environmental performance, safety protection and work efficiency. While improving work efficiency, it reduces the expenditure of manual operation costs and labor costs.

[0040] The fixed position of the hook structure 9 is adjustable, so it can be used for different sizes of ton bags 2. This is an improvement over the traditional method where the hook is fixed by welding, which makes it non-adjustable and can only be used for one type of ton bag, resulting in a single operation.

[0041] The bag clamping cylinder 19 is installed on the surface of the airbag fixing ring seat 21. The airbag fixing ring seat 21 has a hollow structure inside, and the inflatable airbag 20 is located inside the airbag fixing ring seat 21. By placing the inflatable airbag 20 inside the airbag fixing ring seat 21, the overall structure is more compact, reducing the number and volume of external components, which helps to miniaturize the equipment and make better use of space. It is also convenient to arrange other key components in a limited working area, thus improving the space utilization rate of the equipment. At the same time, the pressure generated by the inflatable airbag 20 squeezes the bag opening of the ton bag 2, thereby fixing the bag opening so that materials can enter the ton bag 2. This reduces the process of opening the bag opening and improves work efficiency.

[0042] The hook cylinder 13 is positioned on the surface of the hook fixing seat 16, with one end of the hook cylinder 13 abutting against the surface of the hook 15. The hook cylinder 13 is used to push the hook 15 or to limit the position of the hook 15.

[0043] The hook 15 is limited to the inside of the hook fixing seat 16 by the stop shaft 17, and the anti-drop baffle 14 is rotatably limited to the inside of the hook fixing seat 16. The anti-drop baffle 14 can only rotate inward and cannot rotate outward, which plays the role of preventing the ton bag strap from falling off.

[0044] The height adjustment structure includes a connecting sleeve 11 and a positioning pin 10. The surfaces of the support leg 3 and the connecting sleeve 11 are provided with pin holes 12 for connecting with the positioning pin 10. The connecting sleeve 11 is installed on the surface of the support leg 3 by locking screws and nuts 4. The positioning pin 10 and the support leg 3 are detachable.

[0045] The surface of the feeding dust hood 6 is provided with an exhaust filter 7, one end of which extends into the interior of the feeding dust hood 6. The exhaust filter 7 captures fine dust particles generated during the material filling process, preventing them from being directly discharged into the working environment, reducing air pollution, and playing the role of exhausting and filtering dust.

[0046] A weighbridge 1 is placed below the ton bag 2, and the weighbridge 1 and the ton bag 2 are separate structures.

[0047] The separate structure of the weighbridge 1 provides independent and accurate weight measurement, effectively isolating the impact of vibration from the packing machine on the weight. This structure avoids the influence of these external factors on the weighbridge's weighing accuracy and also reduces safety hazards caused by vibration.

[0048] One end of the hook fixing seat 16 is connected to a baffle 18 that limits the range of motion of the hook 15. The baffle 18 and the hook fixing seat 16 are integrally formed. The baffle 18 limits the range of motion of the hook 15, preventing the hook from falling off accidentally or damaging the equipment due to exceeding the safe range during operation. This structure ensures the stability of the ton bag 2 during suspension, filling and movement. By limiting the maximum displacement of the hook 15, it reduces safety hazards caused by misoperation or mechanical failure, and protects the safety of operators and equipment.

[0049] In this design, when the machine is packaging, the straps on the surface of the ton bag 2 are hung on the hook 15 of the hook structure 9. The air bladder 20 of the bag clamping structure 8 expands under the air pressure provided by the external environment. The powder material enters the ton bag 2 through the feeding dust hood 6 from the bag opening of the clamped ton bag 2. Then, the dust is filtered by the exhaust filter 7 to reduce dust splashing. The weighbridge 1 is used to weigh the ton bag. When it is full, the bag can be replaced.

[0050] When changing bags, the compressed air in the airbag 20 of the bag clamping structure 8 is discharged, the bag clamping cylinder 19 of the bag clamping structure 8 extends, the airbag fixing ring seat 21 descends, the hook cylinder 13 of the hook structure 9 retracts, and the hook 15 is released. After the hook 15 is released, the strap on the surface of the ton bag 2 automatically falls off. The weighbridge 1 weighs the ton bag 2. After the full ton bag 2 is packed and transported away, the hook cylinder 13 of the hook structure 9 extends, the strap of the ton bag 2 is hung on the hook 15 of the hook structure 9, the bag opening of the ton bag 2 is placed on the discharge port of the feed dust hood 6, the bag clamping cylinder 19 of the bag clamping structure 8 retracts, the airbag fixing ring seat 21 rises, and the airbag 20 of the bag clamping structure 8 inflates, thus completing the bag changing operation.

[0051] The fixed position of the hook structure 9 on this simple baling machine is adjustable to accommodate ton bags of different sizes. The hook structure 9 is installed on the slanted tube of the moving platform 5. The position of the hook structure 9 can be moved along the slanted tube and then screwed in to lock it, so as to meet the needs of ton bags of different sizes.

[0052] The support legs of this simple strapping machine have positioning pin holes at different height positions, enabling the simple strapping machine to be height-adjustable: During installation, the pin hole 12 of the support leg 3 is first aligned with the pin hole 12 of the moving platform 5, and then the positioning pin 10 is inserted. The positioning pin 10 has a groove that fits perfectly into the pin hole 12 of the support leg 3. The positioning pin 10 supports the moving platform 5, and the support leg 3 is locked and fixed by the locking screw nut 4 to prevent loosening. The height adjustment requirement of the simple strapping machine is achieved through the pin holes 12 at different height positions on the support leg 3.

[0053] The function of the stop shaft 17 in the hook fixing seat 16 is to ensure that the anti-drop baffle 14 can only rotate inward and cannot rotate outward, so as to prevent the strap of the ton bag 2 from falling off. The function of the baffle is to limit the rotation angle of the hook 15 and effectively prevent the hook cylinder 13 from excessively extending and retracting, causing jamming.

[0054] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
