Description

Technical Field

[0001] This utility model relates to a ton bag device, specifically a ton bag device for preventing the spillage of lithium iron phosphate finished products, belonging to the technical field of lithium iron phosphate finished products. Background Technology

[0002] In the production and processing of lithium iron phosphate products, the packaging process is a key step to ensure product quality and facilitate storage and transportation. Due to the characteristics of lithium iron phosphate particles being small and easily dusted, and the fact that finished products usually need to be packaged in batches by the ton, ton bags have become the main choice for packaging this type of material due to their advantages such as large capacity and ease of mechanized handling. The ton bag packaging of lithium iron phosphate products is mostly completed by semi-automatic equipment. The ton bag opening is opened and fixed below the filling port. The material is transported to the filling port by a conveyor and then poured into the ton bag. After it is full, the ton bag is transported to the next stage by the conveyor equipment.

[0003] In the prior art, such as the ton bag packaging machine disclosed in announcement number CN210503251U, which facilitates the transportation of finished products, the ton bag packaging machine solves the problem of operators moving heavy ton bags by placing ton bags filled with materials on a conveyor belt for short-distance transport. Simultaneously, the full ton bags do not occupy space, allowing the next empty ton bag to be filled. Protective bars restrain the full ton bags, reducing the risk of personal injury to operators if they tilt, thus reducing the occurrence of safety accidents. However, the above-mentioned prior art solutions have the following shortcomings: When using the above-mentioned ton bag packaging machine, the opening and fixing of the ton bags is cumbersome and difficult to precisely align with the filling port. During the filling process, if the bag opening is not tightly secured, lithium iron phosphate particles can easily scatter from the gaps, causing material loss. Simultaneously, the dust raised will pollute the working environment and endanger the health of operators. Furthermore, the material conveying channel of the existing equipment has insufficient sealing, and gaps often exist between the filling port and the ton bag, causing material leakage from the connection between the channel and the bag opening during transportation. Utility Model Content

[0004] The purpose of this invention is to provide a lithium iron phosphate finished product anti-scattering ton bag device to solve the problems of cumbersome operation of opening and fixing of the ton bag, difficulty in accurately connecting with the filling port, easy scattering of lithium iron phosphate particles from the gaps, and the gap between the filling port and the ton bag, which often leads to leakage of materials from the connection between the channel and the bag opening during the transportation process.

[0005] The present invention achieves the above objectives through the following technical solution: a lithium iron phosphate finished product anti-scattering ton bag device, including a frame, a conveyor set below the frame and ton bags placed on the surface of the conveyor, and a discharge machine installed on the top of the frame; Electric telescopic rods are fixed at the four corners of the top surface of the frame. A lifting frame is fixed between the output ends of the four sets of electric telescopic rods. Threaded rods are rotatably connected inside the four corners of the lifting frame. Adjustment motors are fixed on the surface of the four corners of the lifting frame. The output end of the adjustment motor is fixedly connected to the end of the threaded rod. A moving rod is threadedly connected to the surface of the threaded rod. An expansion hook is hinged to the bottom end of the moving rod. The expansion hook is compatible with the hook strap on the surface of the ton bag. The lifting frame has a fixed discharge hopper inside. The discharge hopper has symmetrical hinge seats on both sides of its surface. The hinge seats have symmetrical hinged tilting arms on both sides of their surface. A bag clamp is set between the two sets of tilting arms on the same side.

[0006] As a further improvement of this utility model: a corrugated guide pipe is connected between the discharge end of the discharge machine and the top of the discharge hopper, and a moving groove adapted to the moving rod is opened inside the lifting frame.

[0007] As a further improvement of this utility model: an electric push rod is hinged between the two sets of tilting arms, and a fitting seat is fixed at the bottom of the opposite side of the two sets of tilting arms. The fitting seat is made of rubber and has a shock absorption effect, and the bag clamp is fixed between the two sets of fitting seats.

[0008] As a further embodiment of this utility model: both sides of the surface of the frame near the discharge end of the conveyor are fixed with bonding motors, and the output end of the bonding motor is fixed with a transmission shaft, which is rotatably connected to the surface of the frame.

[0009] As a further embodiment of this utility model: a gear is fixed on the surface of the transmission shaft, a toothed plate is meshed with the surface of the gear, and the toothed plate is slidably connected to the surface of the frame through a positioning frame.

[0010] As a further improvement of this utility model: a push-pull plate is fixed on one side of each of the two sets of toothed plates, and a number of protective frames arranged at equal intervals are fixed on the surface of the push-pull plate.

[0011] As a further improvement of this utility model: a rotating shaft is provided inside the protective frame, and sliding blocks are fixed at both ends of the rotating shaft. The sliding blocks are slidably connected in the sliding groove opened inside the protective frame, and a fitting roller is rotatably connected to the surface of the rotating shaft.

[0012] As a further improvement of this utility model: a pressure sensor is fixed inside the protective frame, the pressure sensor is electrically connected to the bonding motor, and a spring is fixed between the pressure sensor and the sliding block.

[0013] The beneficial effects of this utility model are: This invention, through the coordinated use of an electric telescopic rod, lifting frame, discharge hopper, threaded rod, adjusting motor, moving rod, and expansion hooks, can precisely control the spacing and position of the expansion hooks, ensuring accurate docking with the ton bag hook straps. The moving rod drives the expansion hooks to precisely adjust the spacing, enabling rapid docking with hook straps of different ton bag sizes. Furthermore, the reverse movement evenly expands the bag opening, ensuring a consistent opening angle and smooth edges, laying the foundation for precise docking of the bag opening with the discharge hopper. This reduces preparation time before loading, improves the continuity of batch packaging, and the synchronous opening and closing of the expansion hooks stably expands the ton bag opening, preventing wrinkles or misalignment that could affect loading. This provides a stable channel for subsequent material introduction, reducing material blockage or spillage caused by bag opening issues. Driven by an electric push rod, the two sets of tilting arms rotate relative to each other, causing the bottom fitting seats to move closer together. This allows the bag clamps fixed between the two sets of fitting seats to tightly grip the edge of the bag opening after the ton bag is opened, thus firmly fixing the bag opening to the outlet of the discharge hopper. The rubber fitting seats not only avoid damage to the ton bag from rigid clamping, but also enhance the sealing effect through elastic fitting, effectively preventing materials from scattering from the gap between the bag opening and the discharge hopper during conveying and loading, reducing material waste and environmental pollution. The movement of the push-pull plate can move the protective frame on the surface closer to the ton bag, so that the bonding roller inside the protective frame gradually comes into contact with the side of the ton bag. The lateral support can effectively prevent the ton bag from tilting or shifting due to the weight or expansion of the internal material. Especially during the conveyor process, it can stabilize the posture of the ton bag and avoid the bag opening from loosening or material leakage due to shaking, which significantly reduces the risk of scattering in the conveying process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 like Figures 1 to 7 As shown, a lithium iron phosphate finished product anti-scattering ton bag device includes a frame 1, a conveyor 2 disposed below the frame 1, and a ton bag 3 placed on the surface of the conveyor 2. A discharge machine 4 is installed on the top of the frame 1. Electric telescopic rods 5 are fixed at the four corners of the top surface of the frame 1. A lifting frame 6 is fixed between the output ends of the four sets of electric telescopic rods 5. Threaded rods 9 are rotatably connected inside the four corners of the lifting frame 6. Adjusting motors 10 are fixed on the surface of the four corners of the lifting frame 6. The output end of the adjusting motor 10 is fixedly connected to the end of the threaded rod 9. A moving rod 11 is threadedly connected to the surface of the threaded rod 9. An expansion hook 12 is hinged to the bottom end of the moving rod 11. The expansion hook 12 is compatible with the hook strap on the surface of the ton bag 3. The lifting frame 6 has a discharge hopper 7 fixed inside. The discharge hopper 7 has hinge seats 13 fixed symmetrically on both sides of its surface. The hinge seats 13 have tilting arms 14 hinged symmetrically on both sides of their surfaces. A bag clamp 17 is provided between the two sets of tilting arms 14 on the same side.

[0018] Start the electric telescopic rods 5 at the four corners of the top of the frame 1, which in turn drives the entire lifting frame 6 to rise and fall, lowering the expansion hooks 12 to a height that matches the hook strap of the ton bag 3, facilitating subsequent hooking operations. Then, start the adjusting motors 10 at the four corners of the lifting frame 6, which in turn drive the corresponding threaded rods 9 to rotate. Since the moving rod 11 is threadedly connected to the threaded rod 9 and the moving rod 11 is limited by the moving groove inside the lifting frame 6, the moving rod 11 will move axially along the threaded rod 9, thereby driving the expansion hooks 12 hinged at the bottom to move synchronously. By adjusting the four sets of expansion hooks 1... The spacing of the 2 is adjusted so that it can be precisely aligned and hooked with the four sets of hooks on the surface of the ton bag 3. Then, the motor 10 is adjusted to rotate in the opposite direction, driving the moving rods 11 to move away from each other. The expansion hooks 12 are used to open the bag opening of the ton bag 3, preparing for subsequent filling. The spacing and position of the expansion hooks 12 can be precisely controlled to ensure precise alignment with the hooks on the ton bag 3. Through the synchronous opening and closing of the expansion hooks 12, the bag opening of the ton bag 3 can be stably opened, avoiding bag opening wrinkles or deviations that may affect filling. This provides a stable channel for subsequent material introduction and reduces material blockage or spillage caused by bag opening problems.

[0019] Furthermore, a corrugated guide pipe 8 is connected between the discharge end of the discharge machine 4 and the top of the discharge hopper 7, and a moving groove adapted to the moving rod 11 is opened inside the lifting frame 6.

[0020] As the lifting frame 6 moves downward, the discharge hopper 7 can also move downward. After the opening of the ton bag 3 is opened, the discharge end of the discharge hopper 7 will also extend into the interior of the ton bag 3. Since the discharge end of the discharge machine 4 is connected to the top of the discharge hopper 7 inside the lifting frame 6 through the corrugated guide pipe 8, a closed material conveying channel is formed. The corrugated guide pipe 8 can flexibly extend and retract with the lifting frame 6 to ensure the continuity of material conveying.

[0021] Furthermore, an electric push rod 15 is hinged between the two sets of tilting arms 14, and a fitting seat 16 is fixed to the bottom of the opposite side of the two sets of tilting arms 14. The fitting seat 16 is made of rubber and has a shock absorption effect, and the bag clamp 17 is fixed between the two sets of fitting seats 16.

[0022] On the hinge seats 13 on both sides of the surface of the discharge hopper 7, two sets of flipping arms 14 on the same side rotate relative to each other under the drive of the electric push rod 15, causing the bottom fitting seats 16 to move closer to each other, so that the bag clamp 17 fixed between the two sets of fitting seats 16 tightly clamps the edge of the bag opening after the ton bag 3 is opened. Since the fitting seat 16 is made of rubber, it has a shock absorption effect and can avoid hard collisions. At the same time, it ensures that the bag opening and the outlet of the discharge hopper 7 are tightly fitted, preventing the material from falling out of the gap during filling. With the rubber fitting seat 16, it not only achieves a tight fit between the bag opening and the outlet of the discharge hopper 7, but also uses the elasticity of rubber to avoid wear on the ton bag 3 caused by hard clamping, extending the service life of the ton bag 3, and blocking the path of material falling out of the gap from the bag opening from the source. Especially for materials such as lithium iron phosphate that are easy to generate dust and have fine particles, it effectively reduces material loss during the packaging process.

[0023] Example 2 Improvements based on Example 1: Furthermore, a bonding motor 18 is fixed on both sides of the surface of the frame 1 near the discharge end of the conveyor 2, and a drive shaft 19 is fixed to the output end of the bonding motor 18. The drive shaft 19 is rotatably connected to the surface of the frame 1.

[0024] After the ton bag 3 is filled, the electric push rod 15 retracts, driving the tilting arm 14 to rotate in the opposite direction, causing the bag clamp 17 to loosen the bag opening of the ton bag 3. The adjusting motor 10 drives the threaded rod 9 to rotate, causing the expansion hooks 12 to move closer to each other and separate from the hook strap of the ton bag 3. The electric telescopic rod 5 drives the lifting frame 6 to rise and reset. The conveyor 2 starts to transport the ton bag 3 from the filling position to the next process. At this time, the sticking motors 18 on both sides of the discharge end surface of the frame 1 are activated, thereby driving the transmission shaft 19 to rotate.

[0025] Furthermore, a gear 20 is fixed to the surface of the drive shaft 19, and a toothed plate 21 is meshed with the surface of the gear 20. The toothed plate 21 is slidably connected to the surface of the frame 1 through a positioning frame.

[0026] When the drive shaft 19 rotates, the gear 20 on the surface of the drive shaft 19 rotates accordingly. Since the gear 20 meshes with the gear plate 21 and the gear plate 21 is slidably limited on the surface of the frame 1 by the positioning frame, the gear plate 21 will move in the horizontal direction.

[0027] Furthermore, a push-pull plate 22 is fixed on one side of each of the two sets of toothed plates 21, and several sets of protective frames 23 arranged at equal intervals are fixed on the surface of the push-pull plate 22.

[0028] The toothed plate 21 moves horizontally, causing the push-pull plate 22 fixed on its surface to move synchronously. As the push-pull plate 22 moves, it can drive the protective frame 23 on the surface to move closer to the ton bag 3, so that the bonding roller 28 inside the protective frame 23 gradually gets closer to the side of the ton bag 3.

[0029] Furthermore, a rotating shaft 24 is provided inside the protective frame 23, and sliding blocks 25 are fixed at both ends of the rotating shaft 24. The sliding blocks 25 are slidably connected in the sliding groove opened inside the protective frame 23, and a fitting roller 28 is rotatably connected to the surface of the rotating shaft 24.

[0030] When the bonding roller 28 comes into contact with the filled ton bag 3, it will generate a thrust on the bonding roller 28, causing the sliding blocks 25 at both ends of the rotating shaft 24 to move along the groove inside the protective frame 23 toward the pressure sensor 27 and compress the spring 26.

[0031] Furthermore, a pressure sensor 27 is fixed inside the protective frame 23. The pressure sensor 27 is electrically connected to the bonding motor 18, and a spring 26 is fixed between the pressure sensor 27 and the sliding block 25.

[0032] After the pressure sensor 27 senses the pressure transmitted by the spring 26, it feeds back the signal to the bonding motor 18. The bonding motor 18 controls the start and stop according to the pressure value to ensure that the bonding roller 28 bonds to the side of the ton bag 3 with appropriate pressure. It can automatically adjust the bonding pressure according to the expansion degree of the ton bag 3, ensuring that the bonding roller 28 always supports the side of the ton bag 3 with appropriate pressure, avoiding the material center of gravity shift and bag tilting caused by shaking. The entire process from filling to conveying reduces the risk of material spillage. It is especially suitable for packaging materials such as lithium iron phosphate with uneven density and easy to clump, and can provide lateral support for the ton bag 3 to prevent it from spilling due to the displacement caused by the weight or expansion of the material.

[0033] Working principle: When the device starts working, the electric telescopic rods 5 at the four corners of the top of the frame 1 are activated first, which in turn drives the lifting frame 6 to rise and fall as a whole, so that the expansion hooks 12 are lowered to a height that matches the hook straps of the ton bag 3, which facilitates subsequent hooking operations. Then, the adjustment motors 10 at the four corners of the lifting frame 6 are activated, which in turn drive the corresponding threaded rods 9 to rotate. Since the moving rod 11 is threadedly connected to the threaded rod 9 and the moving rod 11 is limited by the moving groove inside the lifting frame 6, the moving rod 11 will move along the axial direction of the threaded rod 9, which in turn drives the expansion hooks 12 hinged at the bottom to move synchronously. By adjusting the spacing of the four sets of expansion hooks 12, they are precisely aligned with and hooked onto the four sets of hook straps on the surface of the ton bag 3. Then, the adjustment motors 10 rotate in the opposite direction, which drives the moving rods 11 to move away from each other, and the expansion hooks 12 are used to open the bag mouth of the ton bag 3, preparing for subsequent filling. As the lifting frame 6 moves downward, the discharge hopper 7 moves downward as well. After the opening of the ton bag 3 is completed, the discharge end of the discharge hopper 7 extends into the ton bag 3. Since the discharge end of the discharge machine 4 is connected to the top of the discharge hopper 7 inside the lifting frame 6 through the corrugated guide pipe 8, a closed material conveying channel is formed. The corrugated guide pipe 8 can flexibly extend and retract with the lifting frame 6 to ensure the continuity of material conveying. On the hinge seats 13 on both sides of the surface of the discharge hopper 7, the two sets of tilting arms 14 on the same side rotate relative to each other under the drive of the electric push rod 15, causing the bottom contact seats 16 to move closer to each other, so that the two sets of contact seats 16 are fixed together. The clamping hoop 17 tightly grips the edge of the bag opening after the ton bag 3 is opened. Since the fitting seat 16 is made of rubber, it has a shock absorption effect and can avoid hard collisions. At the same time, it ensures that the bag opening and the outlet of the discharge hopper 7 are tightly fitted to prevent materials from falling out of the gaps during filling. With the rubber fitting seat 16, it not only achieves a tight fit between the bag opening and the outlet of the discharge hopper 7, but also uses the elasticity of rubber to avoid wear and tear on the ton bag 3 caused by hard clamping, thus extending the service life of the ton bag 3. It blocks the path of materials falling out of the gaps in the bag opening from the source. Especially for materials such as lithium iron phosphate that are easy to generate dust and have fine particles, it effectively reduces material loss during the packaging process. When the discharge machine 4 is started, the finished lithium iron phosphate is conveyed to the discharge hopper 7 through the corrugated guide pipe 8, and then introduced into the ton bag 3 by the discharge hopper 7 to complete the filling process.

[0034] After the ton bag 3 is filled, the electric push rod 15 retracts, causing the tilting arm 14 to rotate in the opposite direction, which loosens the bag clamp 17 from the opening of the ton bag 3. The adjusting motor 10 drives the threaded rod 9 to rotate, causing the expansion hooks 12 to move closer together and separate from the hook strap of the ton bag 3. The electric telescopic rod 5 drives the lifting frame 6 to rise and reset. The conveyor 2 starts to transport the ton bag 3 from the filling position to the next process. At this time, by starting the motors 18 on both sides of the surface of the frame 1 near the discharge end of the conveyor 2, the drive shaft 19 is driven to rotate. The gear 20 on the surface of the drive shaft 19 rotates accordingly. Because the gear 20 and the gear... Plate 21 meshes, and toothed plate 21 slides and is limited on the surface of frame 1 by positioning frame. Toothed plate 21 will move in the horizontal direction, driving push-pull plate 22 fixed on its surface to move synchronously. As push-pull plate 22 moves, it can drive the protective frame 23 on the surface to move closer to ton bag 3, so that the bonding roller 28 inside the protective frame 23 gradually approaches the side of ton bag 3. When bonding roller 28 contacts the ton bag 3 after filling, it will generate a pushing force on bonding roller 28, causing the sliding blocks 25 at both ends of rotating shaft 24 to move along the sliding groove inside the protective frame 23 towards pressure sensor 27 and compress spring 26. After the pressure sensor 27 senses the pressure transmitted by the spring 26, it feeds back the signal to the bonding motor 18. The bonding motor 18 controls the start and stop according to the pressure value to ensure that the bonding roller 28 bonds to the side of the ton bag 3 with appropriate pressure. It can automatically adjust the bonding pressure according to the expansion degree of the ton bag 3, ensuring that the bonding roller 28 always supports the side of the ton bag 3 with appropriate pressure, avoiding the material center of gravity shift and bag tilting caused by shaking. The entire process from filling to conveying reduces the risk of material spillage. It is especially suitable for packaging materials such as lithium iron phosphate with uneven density and easy to clump, and can provide lateral support for the ton bag 3 to prevent it from spilling due to the displacement caused by the weight or expansion of the material. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
