Description

Technical Field

[0001] This utility model relates to the field of refining agent technology, and in particular to a quantitative packaging device for granular refining agents. Background Technology

[0002] Aluminum alloys require refining agents during the smelting process. Refining agents play a crucial role in removing impurities from the aluminum melt. Existing refining agents are usually prepared by mixing various inorganic salts in a certain proportion after drying, followed by smelting, solidification, crushing, granulation, screening, and packaging processes. However, existing technologies typically require the use of packaging equipment to dispense the refining agents, making it easier for subsequent operators to use them in the required amount and with greater portability.

[0003] For example, in the prior art, there is a quantitative packaging device for granular refining agents, publication number: CN219601655U. When it is necessary to package granular refining agents, the storage box is moved directly under the protective box. At this time, the refining agent is injected into the quantitative tank inside the protective box. When a large amount of refining agent overflows from the quantitative tank, it causes the quantitative tank to flip over, so that the refining agent inside the quantitative tank can be poured into the protective box and then enter the storage box through the bottom of the protective box.

[0004] However, in the existing technology, the volume of the metering tank is fixed, and it is not possible to package materials according to the packaging unit specified by the customer. For example, when the volume of the metering tank is 2 kg and the customer specifies a packaging unit of 5 kg per bag, or when the volume of the metering tank is 5 kg and the customer specifies a packaging unit of 2 kg per bag, the factory operators cannot simply use the metering tank to load and release materials to complete the packaging. Other weighing tools are needed to add or sieve the packaged materials, which seriously affects the packaging efficiency of the materials. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a quantitative packaging device for granular refining agents.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative packaging device for granular refining agents, comprising a mounting base, a packaging box body fixedly connected to the mounting base, a sliding plate slidably connected inside the packaging box body, fixed pulleys rotatably connected to the inner and outer surfaces of the two side walls of the packaging box body, mounting seats fixedly connected to both sides of the outer surface of the packaging box body and below the fixed pulleys, rotating rods rotatably connected inside the mounting seats, take-up rollers fixedly connected to each rotating rod, a brake motor fixedly connected to one side of the mounting seat with its main shaft fixedly connected to the end face of the rotating rod, a transmission rod rotatably connected to the outer surface of one side of the packaging box body without take-up rollers, a transmission rod at the same height as the rotating rod, a first bevel gear fixedly connected to both end faces of the transmission rod, a second bevel gear meshing with the first bevel gear fixedly connected to the end faces of the two rotating rods near the first bevel gears, and a traction rope passing through the fixed pulleys between the take-up rollers and the sliding plate on both sides.

[0007] Preferably, the inner surface of the packing box is provided with slots arranged in a linear array on both sides, and electric push rods are symmetrically arranged on both sides of the sliding plate. The telescopic ends of the two electric push rods are fixedly connected to the locking blocks that cooperate with the slots.

[0008] Preferably, the outer surfaces of both sides of the packing box without take-up rollers are provided with connection ports, and a connecting rod is rotatably connected to each of the two connection ports. A covering strip that completely covers the opening is slidably connected to the connecting rod, and a counterweight is fixedly connected to both ends of the covering strip. The mass of the counterweight located inside the packing box is greater than the mass of the counterweight located outside the packing box.

[0009] Preferably, a storage groove is provided on the outer surface of the fixed pulleys on both sides of the packing box and below the fixed pulleys.

[0010] Preferably, the bottom of the sliding plate is fixedly connected to two abutment blocks arranged along the axial direction of the rotating rod.

[0011] Preferably, two conical slots are symmetrically provided on the sliding plate, an electric telescopic rod is fixedly connected to the bottom of the sliding plate, a conical locking block corresponding to the conical slot is fixedly connected to the telescopic end of the electric telescopic rod, and a discharge port is provided below the sliding plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the brake motor drives the take-up roller to rotate through the transmission rod. During the process, the take-up roller releases the traction rope and the sliding plate fixedly connected to the end of the traction rope, which slides downward along the inside of the packing box and ensures that the bottom of the sliding plate is flush with the slot. Since the material volume and material mass difference between adjacent slots are equal, the capacity of the packing box that can hold material at one time can be quantitatively increased until the material mass corresponding to the packing volume inside the packing box is adjusted to an integer multiple of the packing mass specified by the customer. At this point, it is only necessary to repeat the packing operation, that is, to pack the same number of times according to the corresponding multiple ratio. There is no need to use other weighing tools to add or subtract materials in the packing bag after packing is completed, which greatly improves the packing efficiency.

[0013] 2. In this utility model, when the sliding plate inside the packing box is pulled upward by the traction rope, the upper surface of the sliding plate contacts the counterweight block located inside. During this process, the covering strap folds inside the packing box. Under the traction of the counterweight block located at the outer end, the covering strap slides along the outer surface of the connecting rod and eventually regains its taut state. Repeating the above process, the counterweight block located inside the packing box moves upward with the sliding plate, and at the same time, the slots opened on the inner wall of the packing box are exposed one by one to prevent materials from entering the slots during the feeding process, which would affect the accuracy of the packing capacity. After adjusting to the position corresponding to the appropriate volume, the telescopic end of the electric push rod drives the locking block to extend into the slot, thus fixing the position of the sliding plate.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figure 1-3 As shown, a quantitative packaging device for granular refining agents includes a mounting base 1, a packaging box 2 fixedly connected to the mounting base 1, a sliding plate 3 slidably connected inside the packaging box 2, fixed pulleys 4 rotatably connected to the inner and outer surfaces of the two side walls of the packaging box 2, mounting seats 5 fixedly connected to both sides of the outer surface of the packaging box 2 and below the fixed pulleys 4, rotating rods 6 rotatably connected inside the mounting seats 5, and take-up rollers 7 fixedly connected to each rotating rod 6, a brake motor 8 fixedly connected to one side of the mounting seat 5 with the main shaft fixedly connected to the end face of the rotating rod 6, a transmission rod 9 rotatably connected to the outer surface of one side of the packaging box 2 without take-up rollers 7, at the same height as the rotating rod 6, a first bevel gear 10 fixedly connected to both end faces of the transmission rod 9, a second bevel gear 11 meshing with the first bevel gear 10 fixedly connected to the end faces of the rotating rods 6 near the first bevel gear 10, and a traction rope 12 passing through the fixed pulleys 4 between the take-up rollers 7 on both sides and the sliding plate 3; The inner surface of the packing box 2 is provided with slots 13 arranged in a linear array on both sides. Electric push rods 14 are symmetrically arranged on both sides of the sliding plate 3. The telescopic ends of the two electric push rods 14 are fixedly connected to the locking blocks 15 that cooperate with the slots 13.

[0019] Further explanation of this solution: The brake motor 8 drives the rotating rod 6 and the take-up roller 7 above to rotate. During the process, the take-up roller 7 releases the traction rope 12. The traction rope 12 passes through the fixed pulley 4 and drives the sliding plate 3 at the end to slide down along the inner wall of the packing box 2, increasing the internal volume of the packing box 2. When the material mass corresponding to the internal volume of the packing box 2 is in an integer multiple ratio to the mass of the packing unit specified by the customer, the brake motor 8 stops rotating. The telescopic end of the electric push rod 14 drives the locking block 15 to slide into the locking slot 13 corresponding to the capacity to fix the position of the sliding plate 3. This avoids fatigue of the traction rope 12 and eventual breakage caused by long-term suspension of the sliding plate 3 by the traction rope 12 alone. Meanwhile, in order to ensure that the sliding plate 3 remains balanced during movement, in this scheme, while the brake motor drives the transmission rod 9 on one side to rotate, the second bevel gear 11 set on the other end face of the transmission rod 9 rotates with the brake motor 8 and drives the transmission rod 9 and the first bevel gear 10 set on both end faces of the transmission rod 9 to rotate. This further drives the second bevel gear 11 set on the end face of the rotating rod 6 on the other side of the take-up roller 7 to rotate, thereby driving the take-up roller 7 on the other side of the rotating rod 6 to complete synchronous rotation, realizing synchronous rotation of the take-up rollers 7 on both sides and completing the release or retrieval of the traction rope 12.

[0020] like Figure 3 As shown, two conical slots 21 are symmetrically opened on the sliding plate 3. An electric telescopic rod 23 is fixedly connected to the bottom of the sliding plate 3. A conical locking block 22 corresponding to the conical slots 21 is fixedly connected to the telescopic end of the electric telescopic rod 23. A discharge port 24 is provided below the sliding plate 3.

[0021] The purpose of this solution is as follows: when the inside of the packing box 2 is full of material, the telescopic end of the electric telescopic rod 23 retracts into the telescopic cavity. During the process, the conical block 22 on the telescopic end moves upward synchronously. The conical block 22 then disengages from the conical slot 21, and the material to be packed inside the packing box 2 flows out from the conical slot 21 and finally flows through the discharge port 24 into the packing bag that has been placed at the bottom of the device in advance.

[0022] like Figure 3 As shown, the outer surfaces of both sides of the packing box 2 without take-up rollers 7 are provided with connection ports 16. A connecting rod 17 is rotatably connected to each of the two connection ports 16. A covering strip 18 that completely covers the bayonet 13 is slidably connected to the connecting rod 17. A counterweight 19 is fixedly connected to both ends of the covering strip 18. The mass of the counterweight 19 inside the packing box 2 is greater than the mass of the counterweight 19 outside the packing box 2. The outer surface of the packing box body 2 is provided with fixed pulleys 4 on both sides, and storage slots 20 are provided below the fixed pulleys 4.

[0023] Further explanation of this solution: The mass of the counterweight 19 inside the packaging box 2 is set to be greater than that of the external counterweight 19. This ensures that the counterweight 19 inside the packaging box 2 remains in contact with the upper surface of the sliding block during the movement of the sliding block. At the same time, the external counterweight 19 can pull the covering belt 18 to keep it taut at all times, covering the slot 13 opened on the inner wall of the packaging box 2, thus preventing the material to be packaged from entering the slot 13 and causing loss during the filling process.

[0024] like Figure 2 and Figure 3 As shown, the bottom of the sliding plate 3 is fixedly connected to two abutment blocks 25 arranged along the axial direction of the rotating rod 6.

[0025] The purpose of this solution is to address the issue that when adding packaging materials into the packaging box 2, it is impossible to ensure that the materials are evenly spread on the upper surface of the sliding plate 3. Uneven material distribution will cause the sliding plate 3 to tilt and directly pour the materials into the discharge port 24 and out, making it impossible to achieve quantitative packaging. The solution is to set up the abutment block 25 so that the bottom sides of the sliding plate 3 indirectly restrain the inner wall of the packaging box 2, ensuring that the packaging process is completed smoothly.

[0026] Working principle: Before packing begins, the internal volume of the packing box 2 is adjusted according to the unit packing quantity specified by the customer. Specifically, the brake motor 8 drives the take-up roller 7 to rotate. During the rotation, the take-up roller 7 releases the traction rope 12. The sliding plate 3 at the end of the traction rope 12 moves downward in combination with the guiding action of the fixed pulley 4 and its own gravity, thereby increasing the internal capacity of the packing box 2. This increases the mass of materials that the packing box 2 can hold. After adjustment, materials are added to the packing box 2 until it is level with the top of the box. The telescopic end of the electric telescopic rod 23 drives the conical block 22 to disengage from the conical slot 21. The materials flow out from the conical slot 21 and finally flow into the packing bag that has been placed at the bottom of the device in advance through the discharge port 24.

[0027] In addition, when purchasing products designed in this solution, the density of the packaging material can be provided to the manufacturer in advance. The manufacturer can design the corresponding distance between the slots 13 according to the material density to ensure that the material mass between two adjacent slots 13 is 1 kg, which is convenient for designing the single packaging unit quantity according to the customer's packaging requirements.

[0028] The wiring diagrams of the brake motor 8, electric push rod 14, and electric telescopic rod 23 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the brake motor 8, electric push rod 14, and electric telescopic rod 23 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
