Description

Technical Field

[0001] This invention relates to the field of packaging bag unloading auxiliary devices, and more particularly to a container bag unloading device. Background Technology

[0002] FIBCs (Month Bags) are widely used in building materials, chemicals, grains, food and other fields. They are mainly used to hold various powders and granules. A FIBC opening station is a device that helps to smoothly unload powders (such as flour, cement, lithium iron phosphate powder) and granules (such as wheat, corn, feed) from FIBCs.

[0003] Currently, various types of FIBC (Flexible Intermediate Bulk Container) unloading devices, both domestically and internationally, can only assist in the smooth unloading of materials with good flowability, and their level of automation is low, with manual operation accounting for 50% to 80% of the process. Meanwhile, in the lithium battery industry, severe powder dust creates a harsh working environment, limiting the selection of electrical components and precision mechanical structures, making automation difficult to achieve.

[0004] Therefore, how to reduce manual operation during the unloading process without reducing unloading efficiency has become an urgent problem that most domestic battery cell manufacturers hope to solve. Summary of the Invention

[0005] The purpose of this invention is to provide a container bag unloading device that solves the technical problems of low unloading efficiency of container bags, easy generation of powder dust and impact on the stable operation of machines within the unloading range in the prior art.

[0006] This application discloses a container bag unloading device, including:

[0007] Support frame;

[0008] A hopper is installed on the support frame, and the hopper has an internal cavity for receiving.

[0009] The bag-fixing cones are disposed on the inner wall of the accommodating cavity, and the bag-fixing cones are spaced apart along the circumferential direction of the accommodating cavity;

[0010] The bag-breaking assembly is installed inside the accommodating cavity;

[0011] A discharge pipe is connected to the bottom of the silo, and the discharge pipe extends toward the side away from the silo;

[0012] A drive assembly is installed at the bottom of the hopper, and the output end of the drive assembly extends into the hopper and connects to the bag breaking assembly;

[0013] The bag-breaking assembly includes:

[0014] A bag-breaking knife unit is installed at the output end of the drive component. The bag-breaking knife unit rotates under the drive of the drive component and pushes the material into the discharge pipe.

[0015] An arch-breaking cone unit is installed at the output end of the drive assembly, and the arch-breaking cone unit is located on the side of the bag-breaking knife assembly unit away from the discharge pipe.

[0016] This application is equipped with a hopper, which discharges material inside the cavity, thus avoiding dust generation. At the same time, the bag-breaking component installed inside the cavity ensures stable feeding while breaking the bag, thereby improving the discharge efficiency.

[0017] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0018] Furthermore, the arch-breaking cone unit includes:

[0019] The arch-breaking cone positioning plate is installed at the output end of the drive assembly;

[0020] The arch-breaking cone fixing bolt is installed on the top of the arch-breaking cone positioning plate, and the bottom of the arch-breaking cone fixing bolt extends into the interior of the arch-breaking cone positioning plate and connects to the output end of the drive assembly. The beneficial effect of this step is that the connection method of the arch-breaking cone fixing bolt ensures the stable assembly of the arch-breaking cone positioning plate.

[0021] Furthermore, the arch-breaking cone positioning plate is cone-shaped. The beneficial effect of this step is that the cone shape can better ensure the stability of the container bag.

[0022] Furthermore, the bag-breaking knife assembly unit includes:

[0023] The bag-breaking cutter disc is installed at the output end of the drive assembly;

[0024] Multiple scrapers are installed at intervals on the outer edge of the bag-breaking cutter disc, and the scrapers are distributed at intervals along the circumferential direction of the bag-breaking cutter disc;

[0025] Multiple bag-breaking knives are installed on the scraper, and the cutting edges of the bag-breaking knives extend toward the bag-fixing cone. The beneficial effect of this step is that the scraper and bag-breaking knives can achieve stable material conveying after the bag is broken.

[0026] Furthermore, the bag-breaking knife is shark fin shaped, and the beneficial effect of using this step is that the bag-breaking effect can be improved by using the bag-breaking knife.

[0027] Furthermore, the longitudinal section of the scraper is an unequal-sided triangle, the angle between the side of the scraper facing the turning direction and the plane is α, and the angle between the side of the scraper away from the turning direction and the plane is β, where α < β. The beneficial effect of this step is that the resistance of the scraper when scraping material can be reduced through the design of the tilt angle.

[0028] Furthermore, a positioning pin is provided on the side of the bag-breaking cutter disc facing the arch-breaking cone positioning plate;

[0029] The arch-breaking cone positioning plate has a positioning groove on the side facing the bag-breaking cutter disc that cooperates with the positioning pin. The advantage of this step is that the positioning pin and the positioning groove cooperate with each other to ensure the stability of the connection between the bag-breaking cutter disc and the arch-breaking cone positioning plate.

[0030] Furthermore, a sealing component is connected between the bag-breaking cutter disc and the output end of the drive assembly. The advantage of this step is that the sealing component can ensure the stability of the connection between the drive assembly and the bag-breaking cutter disc.

[0031] Furthermore, the plane at the top of the arch-breaking cone unit is higher than the plane at the top of the bag-fixing cone. The advantage of this step is that by designing the relative positions of the bag-fixing cone and the arch-breaking cone unit, the arch-breaking cone unit can better handle the container bags.

[0032] Furthermore, the driving component is a drive motor or a rotary cylinder;

[0033] The silo is equipped with a dust removal port, and the advantage of this step is that the dust removal port facilitates the dust removal operation.

[0034] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0035] 1. This application places the entire unpacking process of the container bag inside the silo, isolating the dust from the external environment, reducing pollution, lowering the risk of dust explosion, and improving safety.

[0036] 2. This application reduces manual operations, including unpacking, hammering, and cleaning bags, thereby reducing the risk of workers contracting occupational diseases.

[0037] 3. This application has a stable bag-breaking effect. The blade position can be reasonably arranged according to the size of the ton bag to break the bag smoothly. Furthermore, due to the toughness of the ton bag itself, the bottom of the ton bag will not be completely broken, and the waste ton bag can be recycled normally. Attached Figure Description

[0049] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0050] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0053] Example:

[0054] like Figure 1-6 As shown in the figure, this application discloses a container bag unloading device for unloading materials from container bags, replacing manual operation, while ensuring a clean operating environment;

[0055] like Figure 1 , 2 As shown, its specific structure includes:

[0056] Support frame 1, which can be welded from multiple metal parts, and its top can be welded with corresponding connectors to fix it to the outer wall of the subsequent hopper to support the corresponding hopper;

[0057] The hopper 2 is installed on the support frame 1, and the hopper 2 has an internal cavity 201. The hopper 2 can be a conical hopper, and its cavity is used to place the corresponding container bags. When the bags are broken later, a relatively closed space can be formed to reduce dust.

[0058] The bag-fixing cone 3 is disposed on the inner wall of the accommodating cavity 201, and the bag-fixing cone 3 is distributed at intervals along the circumferential direction of the accommodating cavity 201. The bag-fixing cone 3 is used to ensure that the container bag is stably placed inside the hopper 2, which facilitates the subsequent bag breaking operation.

[0059] The bag-breaking assembly 4 is installed inside the accommodating cavity 201, with the bag-breaking end of the bag-breaking assembly 4 facing upward, and is used to break the container bag.

[0060] The discharge pipe 5 is connected to the bottom of the hopper 2 and extends away from the hopper 2. That is, the discharge pipe 5 is used to transport the material after the container bag is broken. The material in this application refers to the material in the container bag.

[0061] The drive component 6 is installed at the bottom of the hopper 2, and the output end of the drive component 6 extends into the hopper 2 and is connected to the bag breaking component 4. The drive component 6 is used to provide power, specifically located on the outside of the hopper 2, to drive the corresponding bag breaking component 4 to rotate and complete the breaking of the container bag.

[0062] Regarding the methods of breaking the bag, such as Figure 2 As shown, this application designs the bag-breaking assembly 4, setting up a corresponding knife unit to replace manual bag breaking, and also providing supporting components to ensure that the knife unit can stably break bags during operation; its specific structure includes:

[0063] The bag-breaking knife unit 7 is installed at the output end of the drive component 6. The bag-breaking knife unit 7 rotates under the drive of the drive component 6 and pushes the material into the discharge pipe 5.

[0064] The arch-breaking cone unit 8 is installed at the output end of the drive assembly 6, and the arch-breaking cone unit 8 is located on the side of the bag-breaking knife assembly unit 7 away from the discharge pipe 5.

[0065] In actual operation, the arch-breaking cone unit 8 is used to secure the container bag. Because the container bag contains materials and is quite heavy, if it tilts, it will affect the working efficiency of the bag-breaking knife unit 7. Thus, the arch-breaking cone unit 8 effectively prevents the container bag from tilting. At the same time, in this application, the bag-breaking knife unit 7 performs the bag-breaking operation, and under the drive of the corresponding drive component 6, it can push the material into the discharge pipe to complete the feeding function.

[0066] To further ensure, such as Figure 3 As shown, to improve the stability of the container bag during placement, this application further designs the anti-bridging cone unit, wherein the anti-bridging cone unit 8 includes:

[0067] The arch-breaking cone positioning plate 801 is installed at the output end of the drive assembly 6;

[0068] The arch-breaking cone fixing bolt 802 is installed on the top of the arch-breaking cone positioning plate 801, and the bottom of the arch-breaking cone fixing bolt 802 extends into the interior of the arch-breaking cone positioning plate 801 and connects to the output end of the drive assembly 6. The arch-breaking cone fixing bolt 802 is relatively long and has a conical top, which is used to fix the corresponding container bag and prevent it from shaking. At the same time, the bottom of the arch-breaking cone fixing bolt 802 is used for connection, passing through the entire arch-breaking cone positioning plate 801 so that the arch-breaking cone positioning plate 801 can be stably fitted onto the output end of the drive assembly 6.

[0069] Considering the state of the container bag inside the silo, this application designs the shape of the arch-breaking cone positioning plate 801 to be cone-shaped, which can better fit the bottom of the container bag and make it more stable when breaking the bag.

[0070] To further ensure the efficiency and effectiveness of bag breaking, this application makes further designs to the bag breaking knife assembly unit 7, such as... Figure 5 , 6 As shown, it specifically includes:

[0071] The bag-breaking cutter disc 803 is installed at the output end of the drive assembly 6 and moves synchronously with the output end of the subsequent drive assembly 6, so that it can stably drive the scraper to rotate.

[0072] Multiple scrapers 804 are installed at intervals on the outer edge of the bag-breaking cutter disc 803, and the scrapers 804 are distributed at intervals along the circumferential direction of the bag-breaking cutter disc 803.

[0073] Multiple bag-breaking knives 805 are mounted on the scraper 804, and the cutting edges of the bag-breaking knives 805 extend toward the bag-fixing cone 3. In this application, the scraper 804 is used to convey materials, while the bag-breaking knives 805 are used to break bags. When the scraper 804 rotates under the drive of the drive assembly 6, it can drive the scraper 804 to rotate, thereby completing the rotation of the bag-breaking knives 805, thus completing the bag-breaking operation of the entire container bag. At the same time, the scraper 804 rotates, thereby driving the material flow and causing it to enter the discharge pipe 5.

[0074] Specifically, the bag-breaking knife 805 can be of various designs, including a shark fin shape, as long as it can successfully break open the container bag.

[0075] When the scraper 804 rotates, the material can be fed. In order to further improve the material feeding efficiency, this application designs the scraper 804 to be a triangular pyramid with an unequal-sided triangle in longitudinal section. Specifically, the angle between the side of the scraper 804 facing the direction of rotation and the plane is α, and the angle between the side of the scraper 804 away from the direction of rotation and the plane is β, where α < β. This can better push the material and make it stably enter the discharge pipe 5.

[0076] Regarding the connection between the bag-breaking knife assembly unit 7 and the arch-breaking cone unit 8, this application provides further explanation. Both are driven to rotate by the drive assembly 6. In order to ensure stability during bag breaking, it is necessary to ensure that there is no relative movement between the bag-breaking knife assembly unit 7 and the arch-breaking cone unit 8. Therefore, a positioning pin 806 is provided on the side of the bag-breaking knife disc 803 facing the arch-breaking cone positioning plate 801.

[0077] The arch-breaking cone positioning plate 801 has a positioning groove 807 on the side facing the bag-breaking cutter disc 803, which cooperates with the positioning pin 806. During assembly, the positioning groove 807 of the arch-breaking cone positioning plate 801 is engaged with the positioning pin 806 of the bag-breaking cutter disc 803. At the same time, the arch-breaking cone positioning plate 801 is also connected by the arch-breaking cone fixing bolt 802, so that the arch-breaking cone positioning plate 801 will not move relative to the bag-breaking cutter assembly unit 7 when rotating, thus affecting stability.

[0078] To prevent material from flowing out of the area outside the discharge pipe 5 in the hopper 2, a sealing component 9 is connected between the bag breaking cutter disc 803 and the output end of the drive component 6, that is, the sealing component 9 is used for sealing.

[0079] Regarding the sealing component 9, such as Figure 4 As shown, to further explain, a groove 808 is provided at the bottom of the bag-breaking cutter disc 803. The groove 808 is divided into a first section and a second section, wherein the first section is located above the second section and the first section is annular.

[0080] The sealing assembly 9 includes a seal 901, a lip seal 902, and a wear-resistant seal 903;

[0081] The top of the seal 901 extends into the first section of the groove 808, and its middle part cooperates with the protruding part in the middle of the bag-breaking blade 803 to ensure the stability of the seal 901 after assembly.

[0082] Meanwhile, the lip seal 902 is located inside the first section of the groove 808 and is also assembled to the top of the seal 901, further improving the sealing performance;

[0083] A protruding section is provided in the middle of the seal 901. The protruding section is located inside the second section to form a seal. A labyrinth groove is provided on its upper end face. A wear-resistant sealing ring 903 is provided inside the labyrinth groove to ensure the sealing performance.

[0084] Meanwhile, the sealing element 901 is provided with an air sealing channel 904. The end of the air sealing channel 904 corresponds to the output end of the drive component. By introducing the corresponding compressed gas, powder can be prevented from entering the output end of the drive component and affecting the stable operation of the overall device.

[0085] During assembly, the output end of the drive assembly 6 passes through the seal 901. Therefore, at least four packing rings 905 and one packing ring cap 906 are provided between the output end of the drive assembly 6 and the seal 901. The packing ring cap can be used to press the packing rings, thus ensuring the sealing between the drive assembly 6 and the bag-breaking blade disc 803.

[0086] To further ensure the stability of the container bags, the top plane of the arch-breaking cone unit 8 is higher than the top plane of the bag-fixing cone 3. Because the container bags are heavy, when pressed down, the surrounding container bags will move down and cooperate with the bag-fixing cone.

[0087] Specifically, the drive component 6 is a drive motor or a rotary cylinder, which can realize the rotation function. The hopper 2 is provided with a dust removal port 10 for connecting to a negative pressure dust collector to improve the dust removal effect.

[0088] The specific work process for this application is as follows:

[0089] Remove the top cover of hopper 2, and use a gantry crane to hoist the full-filled container bag into hopper 2 until the gantry crane is no longer under load and the weight of the container bag is entirely borne by hopper 2. At this point, the breaking cone unit 8 will penetrate the container bag. Close the top cover of hopper 2, and use the gantry crane to lift the container bag. Turn on the lower drive assembly (i.e., the geared motor), and the bag-breaking knife unit 7 will start rotating. The knife assembly has scraping angles that can scrape the material on the bottom plate of the hopper out through the discharge pipe 5. After the geared motor has been turned on for a period of time, the gantry crane will be lowered again, and the breaking... The arch cone unit 8 secures and stabilizes the container bag. The bag-breaking knife unit 7 rotates, and the bag-breaking knife on the knife unit cuts open the bottom of the container bag, allowing a large amount of material to flow to the bottom plate of the silo. The scraper 804 scrapes the material out from the discharge pipe 5. After a period of time, the overhead crane is lifted up, and the material accumulates on the bottom plate of the silo. At this time, the scraper 804 mainly plays the role of scraping the material. The overhead crane is repeatedly lifted and lowered several times until it is finally lifted up. The dust collector is turned on, and after a period of dust removal, the top cover of the silo 2 is opened, and the overhead crane removes the empty container bag. After collection, the new process is repeated.
