Description

Technical Field

[0001] The utility model relates to the technical field of material transfer, and particularly relates to a ton bag unpacking device. Background Art

[0002] A ton bag is a flexible transportation packaging container. It has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient strength in structure. With a crane or forklift, it can achieve containerized unit transportation. Since the loading, unloading and handling of ton bags are very convenient and the loading and unloading efficiency is significantly improved, ton bags are also widely used in smelting plants to load ore powder. However, the ore powder is easy to freeze and form lumps in winter and cannot be directly used. It needs to be thawed or broken and crushed by an excavator before use. The bag-breaking efficiency is relatively low, which restricts the production site, affects the transfer of production goods, increases the production load and leads to an increase in production costs.

[0003] After retrieval, a Chinese patent with the publication number CN212314103U discloses a rapid ton bag breaking device. When in use, the rapid ton bag breaking device can be installed on a silo, and the ton bag is lifted by the lifting hook of a hoisting machine. During the slow feeding process of the ton bag by the lifting hook, the bag-breaking blade pierces the ton bag. As the lifting hook continues to fall, most of the weight of the ton bag is borne by the bracket. At the same time, the bag-breaking blade and the connecting piece are inserted into the ton bag together. At this time, the lifting hook stops falling, the bag-breaking blade nails the ton bag, and then the jacking mechanism is controlled to extend. Under the action of the jacking mechanism, the connecting piece tears the ton bag fixed on the bag-breaking blade, so that the objects in the ton bag flow out, playing a role in rapid unloading. Finally, the connecting piece retracts and returns to the initial state. A Chinese patent with the patent number CN220054460U discloses a material ton bag breaking and processing device, which initially breaks the frozen materials inside with a first hydraulic cylinder, and uses a scraping nail plate to limit the stroke of the first hydraulic cylinder.

[0004] The existing technologies have the following problems: the structure of the ton bag bag-breaking device is complex and the operation is inconvenient; the internal structure of the bag-breaking bin of the ton bag breaking and processing device is complex, and the bag-breaking nail plate is integral, so the maintenance cost is relatively high when the bag-breaking nails are damaged.

[0053] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0054] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0055] The inventor found in practice that in winter, it is necessary to thaw frozen ton bags or use an excavator to break and crush them before use. The bag-breaking efficiency is relatively low, restricting the production site, affecting the transfer of production goods, increasing the production load, and resulting in an increase in production costs. At present, the ton bag bag-breaking mechanism has a complex structure and is inconvenient to operate; on the inner sides of the left and right side walls of the bag-breaking bin, there are bag-breaking nail plates, and a scraping nail plate is fixedly connected in front of the bag-breaking nail plates. The surface of the scraping nail plate is provided with a plurality of nail holes for the nails on the bag-breaking nail plates to pass through. Its structure is complex and the maintenance cost is high.

[0056] Based on the above findings, the present application proposes a bulk bag unpacking device. By using the perforated conveyor component, roller conveyor belt, and rotary saw of the bulk bag cutting mechanism, the bottom of the bulk bag is cut while the bulk bag is being conveyed, improving work efficiency. The unpacking nails in the crushing mechanism are detachably connected to the hydraulic plate, facilitating the replacement of damaged unpacking nails and reducing maintenance costs. Embodiment

[0057] Refer to Figures 1 to 13 As shown, the present application discloses a bulk bag unpacking device, which includes a cutting mechanism 1, a crushing mechanism 2, a collection mechanism 3, a conveying mechanism 4, a bag-hooking mechanism 5, and a bracket 6. Along the conveying direction, it successively includes a cutting mechanism 1 and a crushing mechanism 2. The crushing mechanism is arranged on the bracket 6. A collection mechanism 3 is arranged below the crushing mechanism, a bag-hooking mechanism 5 is arranged above the crushing mechanism, and a conveying mechanism 4 is arranged below the collection mechanism 3.

[0058] The cutting mechanism 1 includes a perforated conveyor component 101 and a cutter arranged below the perforated conveyor component 101 for cutting the bottom of the bulk bag. The perforated conveyor component 101 includes a perforated conveyor belt 102 and a roller conveyor belt 103 arranged directly above the perforated conveyor component 101. The roller conveyor belt 103 is composed of rollers, bearings, and a frame. While the rollers convey the bulk bag towards the crushing mechanism 2, they lift the bulk bag, facilitating the cutter located directly below the holes of the perforated conveyor belt 101 to cut the bottom of the bulk bag. The cutter is located directly below the holes of the perforated conveyor belt 101 and is composed of a transmission shaft 104 and a rotary saw 105, which are connected by a locking sleeve. The rotation of the transmission shaft 104 drives the rotation of the rotary saw 105, enabling the bottom of the bulk bag to be automatically cut during the conveying process, improving the bag-breaking efficiency.

[0059] Refer to Figures 6 to 12 As shown, the crushing mechanism 2 includes a crushing box 201 and crushers arranged on opposite two open sides of the crushing box 201. The crushing box 201 is cuboid-shaped, with the front hinged by a hinge 204, equal-sized holes opened on both sides, with a clearance fit with the hydraulic plate 202 in terms of size, and the upper and lower surfaces are fully open and the interior is completely empty. The crushers include a hydraulic rod 205, a hydraulic plate 202, and unpacking nails 203. One end of the hydraulic rod 205 is fixedly connected to the hydraulic plate 202, and the other end is connected to a motor. The motor drives the crushers to reciprocate along the holes on both sides of the crushing box 201. The hydraulic plate 202 is detachably connected to the unpacking nails 203, such as by screw connection.

[0060] Specifically, the material of the bag-breaking nail 203 is alloy steel. The length of the barbs of the bag-breaking nail 203 is 30 cm. The tip spacing between two adjacent rows of bag-breaking nails 203 on one hydraulic plate 202 is 30 cm. The bag-breaking nails 203 on the two hydraulic plates 202 are distributed in a staggered pattern. When the two hydraulic plates 202 are combined, the tip spacing of their bag-breaking nails 203 is 15 cm. The hydraulic plate 202 is made of a 10-cm-thick steel plate, with a height of 1.8 - 2 meters and a width of 1.8 - 4 meters. The width of the hydraulic plate 202 is determined by the number of bags broken at one time. The maximum hydraulic pressure is 26.5 MPa, and the hydraulic stroke is 1.6 m. The size and number of the bag-breaking nails 203 are designed according to the required crushing particle size in production.

[0061] The collection mechanism 3 includes a funnel 301 and a separator net 302. The separator net 302 is installed on the bracket 6 directly below the crushing mechanism 2 to prevent large pieces of goods and ton bags from falling. The size of the separator net is 12 cm × 12 cm, and it is made of steel bars with a diameter of 8 mm. The funnel 301 is installed on the bracket 6 directly below the separator net 302 and is used to collect the ore powder falling from the crushing mechanism 2. One end of the conveying mechanism 4 is connected below the funnel 301 to convey the ore powder falling on the conveyor belt 401 to the ore powder pile for convenient centralized collection.

[0062] The usage process of the present utility model is as follows:

[0063] 1. Using the transmission principle of the perforated conveyor component 101 and the roller conveyor belt 103, the ton bag is conveyed to the cutting mechanism 1. The rotating electric saw 105 is driven by the transmission shaft 104 to cut open the bottom of the ton bag. The crushing box 201 of the crushing mechanism 2 is opened, and then the ton bag is hooked into the middle of the crushing mechanism 2 by the bag-hooking mechanism 5.

[0064] 2. The ton bag is suspended inside the crushing box 201 by the bag-hooking mechanism 5. The position of the ton bag is adjusted so that the ton bag is in the middle of the crusher, and the crushing box 201 is closed.

[0065] 3. The motor is started. The motor drives the crusher to move towards the center of the crushing box 201 to squeeze the ton bag. The barbs of the bag-breaking nails 203 intersect, causing most of the caked ore powder to be crushed into lumps with a diameter less than 10 cm. Subsequently, the motor drives the crusher to return to half of its travel and then squeezes again, so that the remaining ore powder is all crushed into small pieces less than 10 cm. The motor is turned off, and the crusher returns to its original position.

[0066] 4. The crushed ore powder passes through the separator net 302 and is collected by the funnel 301, and slides down the side wall of the funnel 301 onto the bottom conveying mechanism 4. The conveying mechanism 4 conveys the crushed ore powder to the ore powder pile.

[0067] 5. After the bag is broken, the bag-hooking mechanism 5 lifts the ton bag, rotates it to one side, and then collects it.

[0068] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
