但在使用过程中发现,液压杆推动破袋割刀对吨包进行破袋,开口较窄、开口面积有限,容易导致物料下料不畅,且缺少对物料的进一步处理,无法完整实现从拆袋到投料流程
[0024]In this invention, a ton bag containing caustic soda flakes is first suspended and lifted above the cross beam inside the frame by a hoisting mechanism. Then, the hoisting mechanism is controlled to descend, causing the ton bag to slowly descend until the bottom of the ton bag contacts the tip of the cross cone. Since the cross cone is mounted on the cross beam with its tip facing upwards, the outer edges of the four inclined edges gradually narrow from wide to narrow, forming a cutting edge. As the ton bag continues to descend under its own weight, the cutting edge can cut open the bottom of the ton bag, and the caustic soda flakes inside flow out from the opening and fall into the collection cylinder below. The collection cylinder has a funnel-shaped structure that is wider at the top and narrower at the bottom. After the material is collected, it enters the crusher from the discharge port for crushing. The crushed material is then transported to the alkali dissolving tank by a tubular chain conveyor. This achieves mechanized unpacking and conveying of ton bag caustic soda flakes, solving the problem of time-consuming and labor-intensive manual feeding of small packages in the prior art, and achieving the effect of saving manpower and improving feeding efficiency.

[0002] Currently, in chemical production, alkaline materials such as caustic soda flakes often need to be dissolved in a dissolving tank. Traditionally, this involves manual feeding in small packages, which is not only labor-intensive and inefficient but also poses certain safety hazards. With the expansion of production scale, the use of ton-packaged alkaline materials is becoming increasingly common.

This mechanism includes a feeding machine support, a feeding hopper, a bag-breaking cutter, and a lifting electric hoist. A hydraulic rod drives the bag-breaking cutter to break the ton bags, and a fan-type hopper top dust collector is used for dust collection. However, during use, it was found that the hydraulic rod-driven bag-breaking cutter results in a narrow opening with a limited area, easily leading to poor material feeding. Furthermore, it lacks further material processing and cannot fully realize the process from bag opening to feeding. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a ton bag unpacking and feeding device that can effectively break open ton bags, realize unpacking, conveying and feeding, improve feeding efficiency and reduce labor intensity.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a ton-bag unpacking and feeding device for feeding materials into a dissolving alkali tank, comprising:

[0007] A hoisting mechanism is disposed inside the frame and above the cross beam, and the hoisting mechanism is adapted to suspend and lift ton bags;
[0008] A material collecting cylinder is disposed inside the frame, below the cross beam, and a discharge port is provided below the material collecting cylinder;

[0010] A pulverizer connected to the discharge port of the collecting cylinder;
[0011] A tubular chain conveyor, wherein the inlet of the tubular chain conveyor is connected to the outlet of the crusher, and the outlet of the tubular chain conveyor is adapted to connect to the alkali dissolving tank.
[0012] Furthermore, a specific structure for a hoisting mechanism is provided, the hoisting mechanism comprising:
[0013] A guide rail is mounted above the frame;
[0014] An electric hoist, wherein the electric hoist is mounted on the guide rail and can move along the guide rail;
[0015] The hook frame is connected to the electric hoist via a lifting rope.
[0016] Furthermore, the hook frame has a cross-shaped structure and is equipped with a limiting hook.
[0017] Furthermore, the collecting cylinder has a funnel-shaped structure that is wider at the top and narrower at the bottom.
[0018] Furthermore, the ton bag unpacking and feeding device also includes a filter screen, which is installed at the top opening of the collecting cylinder.

[0023] By adopting the above technical solution, this utility model has the following beneficial effects:
[0024] In this invention, a ton bag containing caustic soda flakes is first suspended and lifted above the cross beam inside the frame by a hoisting mechanism. Then, the hoisting mechanism is controlled to descend, causing the ton bag to slowly descend until the bottom of the ton bag contacts the tip of the cross cone. Since the cross cone is mounted on the cross beam with its tip facing upwards, the outer edges of the four inclined edges gradually narrow from wide to narrow, forming a cutting edge. As the ton bag continues to descend under its own weight, the cutting edge can cut open the bottom of the ton bag, and the caustic soda flakes inside flow out from the opening and fall into the collection cylinder below. The collection cylinder has a funnel-shaped structure that is wider at the top and narrower at the bottom. After the material is collected, it enters the crusher from the discharge port for crushing. The crushed material is then transported to the alkali dissolving tank by a tubular chain conveyor.

[0026] In summary, this utility model achieves mechanized unpacking of ton bags by using a cross-shaped cone blade structure in conjunction with a hoisting mechanism. Combined with a crusher and a tubular chain conveyor, it completes the crushing and conveying of materials, replacing the original manual unpacking and feeding method, reducing labor intensity, improving feeding efficiency, and ensuring the continuity and reliability of the unpacking and feeding process.

[0033] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0034] like Figure 1-6 As shown, a ton-bag unpacking and feeding device is used to feed materials into a dissolving alkali tank, comprising:
[0035] Frame 1, which is a square cylindrical structure, and a cross beam 2 is installed inside the frame 1;
[0036] The hoisting mechanism 3 is located inside the frame 1, above the cross beam 2, and is suitable for suspending and lifting the ton bag;
[0037] The material collection cylinder 4 is installed inside the frame 1, below the cross beam 2, and has a discharge port at the bottom.
[0038] A cross cone 5 is mounted on a cross beam 2. The cross cone 5 includes four inclined edges that intersect to form a cone tip with the tip pointing upwards. The outer edge of each edge gradually narrows from wide to narrow to form a blade 51.
[0039] Crusher 6 is connected to the discharge port of collecting cylinder 4;
[0040] The tubular chain conveyor 7 has its inlet connected to the outlet of the crusher 6, and its outlet is suitable for connecting to the alkali dissolving tank.
[0041] In this embodiment, as Figure 1-4 and Figure 6 As shown, firstly, the ton bag containing caustic soda flakes is suspended and lifted above the cross beam 2 inside the frame 1 by the hoisting mechanism 3. Then, the hoisting mechanism 3 is controlled to descend so that the ton bag slowly descends. The bottom of the ton bag contacts the tip of the cross cone 5. Since the cross cone 5 is installed on the cross beam 2 with the tip facing upward, the outer edges of the four inclined edges gradually change from wide to narrow to form blades 51. When the ton bag continues to descend under its own weight, the blades 51 can cut open the bottom of the ton bag. The caustic soda flakes inside the ton bag flow out from the opening and fall into the collection cylinder 4 below. The collection cylinder 4 is a funnel-shaped structure that is larger at the top and smaller at the bottom. After the material is collected, it enters the crusher 6 from the discharge port for crushing. The crushed material is transported to the alkali dissolving tank through the tubular chain conveyor 7. This realizes the mechanized unpacking and conveying of ton bag caustic soda flakes, which solves the problem of time-consuming and labor-intensive manual feeding of small packages in the existing technology, and achieves the effect of saving manpower and improving feeding efficiency.
[0042] Specifically, such as Figure 2As shown, the hoisting mechanism 3 includes:
[0043] Guide rail 31 is mounted on top of frame 1;
[0044] Electric hoist 32, which is mounted on guide rail 31 and can move along guide rail 31;
[0045] The hook frame 33 is connected to the electric hoist 32 via the hoisting rope 34.
[0046] Specifically, such as Figure 2 As shown, the hook frame 33 has a cross-shaped structure and is equipped with a limit hook.
[0047] Specifically, such as Figure 6 As shown, the collecting cylinder 4 has a funnel-shaped structure that is larger at the top and smaller at the bottom.
[0048] Specifically, such as Figure 4 As shown, the ton bag unpacking and feeding device also includes a filter screen 9, which is set at the top opening of the collecting cylinder 4.
[0049] In this embodiment, as Figure 4 and Figure 6 As shown, the filter screen 9 has a large mesh size. When the caustic soda flakes fall from the broken ton bag, the filter screen 9 blocks impurities such as ton bag fragments and binding ropes from entering the collection cylinder 4, while the caustic soda flakes fall into the collection cylinder 4 through the mesh, thus achieving the separation of the material from the packaging debris that has mistakenly entered.
[0050] Specifically, such as Figure 2 and Figure 4 As shown, the cross cone 5 is located above the center of the filter screen 9.
[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the cross cone 5 is located above the center of the filter screen 9, with the cone tip higher than the plane of the filter screen 9. The cone tip of the cross cone 5 first contacts the bottom of the ton bag, and the blade 51 cuts along the warp and weft directions of the fabric at the bottom of the ton bag. The four edges apply cutting force in four directions respectively, so that the bottom of the ton bag forms a cross-shaped opening. After the opening, the bottom of the ton bag expands outwards, and the material flows out from the opening and is dispersed to the surrounding area of the filter screen 9, avoiding the material from accumulating in the center of the filter screen 9 and causing blockage.
[0052] Specifically, such as Figure 4 As shown, the ton bag unpacking and feeding device also includes a support rod 52, which is vertically installed on the cross beam 2. The upper end of the support rod 52 is fixedly connected to the cone tip formed by four inclined edges.
[0053] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the support rod 52 is vertically installed on the cross beam 2. The upper end of the support rod 52 is fixedly connected to the cone tip formed by four inclined edges. When the ton bag presses against the cross cone 5 under its own weight, the support rod 52 transmits the downward force borne by the cross cone 5 to the cross beam 2. The cross beam 2 then distributes the force to the four side walls of the frame 1 to prevent the cross cone 5 from shifting or deforming during the cutting process and to maintain the contact angle and cutting depth between the blade 51 and the bottom of the ton bag.
[0054] Specifically, the discharge port of the collecting cylinder 4 is equipped with a gate valve (not shown in the figure).
[0055] In this embodiment, a gate valve is installed at the discharge port of the collecting cylinder 4. When the gate valve is open, its valve plate is parallel to the material flow channel, allowing material to flow from the collecting cylinder 4 to the crusher 6. When the gate valve is closed, its valve plate is perpendicular to the material flow channel, blocking the material flow. The opening and closing state of the gate valve is controlled to regulate the time and flow rate of material entering the crusher 6. In this embodiment, the gate valve is a pneumatic gate valve, driven by a pneumatic actuator. In other embodiments, the gate valve can also be an electric gate valve or a manual gate valve.
[0056] Specifically, such as Figure 6 As shown, the ton bag unpacking and feeding device also includes two vibrators 10, which are evenly distributed on the outer wall of the collecting cylinder 4.
[0057] In this embodiment, as Figure 6 As shown, two vibrators 10 are evenly distributed on the outer wall of the collecting cylinder 4. The vibration generated by the vibrators 10 during operation is transmitted through the cylinder wall of the collecting cylinder 4 to the inner wall surface, causing the caustic soda flakes adhering to the inner wall to fall off. At the same time, it breaks the bridging structure formed by the material inside the collecting cylinder 4, causing the material to move along the inclined inner wall of the collecting cylinder 4 towards the discharge port. In some embodiments, the number of vibrators 10 is not limited to two, and can be set according to the volume of the collecting cylinder 4 and the characteristics of the material.
[0058] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
