Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a double-headed weighing and packaging machine with an improved version. Background Technology

[0002] Granular materials usually need to be counted before being filled into packaging containers. Currently, this is generally done by manual weighing, which is slow and labor-intensive. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of slow material weighing speed in the prior art, thereby providing a fast double-head weighing and packaging machine with lifting function.

[0004] Therefore, this utility model provides a dual-head weighing and packaging machine with an improved version, including a frame, a feeding bin, two feeding channels, a replenishing channel, and two weighing modules. The feeding bin is located on the frame and is used to store and convey materials. The two feeding channels are arranged side by side and are suitable for receiving materials from the feeding bin and conveying them to the corresponding waiting bins. The replenishing channel is located between the two feeding channels, and the end of the replenishing channel is provided with a replenishing direction control bin, which is used to replenish the corresponding waiting bin. The two weighing modules are respectively located below the corresponding waiting bins and are used to weigh the materials.

[0005] The feeding direction control chamber includes two feeding ports and two feeding port opening and closing components. The two feeding ports are correspondingly set with the corresponding waiting hoppers. The two feeding port opening and closing components control the opening or closing of the corresponding feeding ports. The feeding port opening and closing components include a feeding baffle and a feeding cylinder for controlling the movement of the feeding baffle.

[0006] The discharge port of the feed hopper is provided with a first baffle plate corresponding to the two feeding channels and the replenishment channel.

[0007] The material storage bin is equipped with a second baffle plate for controlling the opening and closing of its discharge port, and a second cylinder for controlling the movement of the second baffle plate.

[0008] Below the two material storage bins is a discharge bin, which includes a qualified product discharge port and a non-qualified product discharge port, respectively located on both sides of the discharge bin. The non-qualified product discharge port is correspondingly set with the material storage bin. Two discharge port opening and closing components control the opening or closing of the corresponding qualified product discharge port and non-qualified product discharge port, respectively. The discharge port opening and closing components include a discharge baffle and a discharge cylinder for controlling the movement of the discharge baffle.

[0009] It also includes a transfer bin and a power mechanism. The transfer bin is installed on the gantry frame and can be moved up and down via a lifting arm. The transfer bin is adapted to receive materials from the material bin and transfer them to the feed bin. The power mechanism is connected to the lifting arm and is adapted to drive the lifting arm to move up and down.

[0010] The material silo is provided with a third baffle plate corresponding to the transfer silo at the discharge port, and a third cylinder for controlling the opening and closing of the third baffle plate.

[0011] The transfer bin is rotatably mounted on the lifting arm, and has an initial position where it is placed horizontally on the lifting arm, and an inclined pouring position. The lifting arm is provided with a pouring cylinder located at the bottom of the transfer bin, and the pouring cylinder drives the transfer bin to switch between the initial position and the pouring position.

[0012] The discharge port of the transfer bin is provided with a fourth baffle plate and a fourth cylinder for controlling the opening and closing of the fourth baffle plate.

[0013] The technical solution of this utility model has the following advantages:

[0014] 1. The dual-head weighing and packaging machine with improved efficiency provided by this utility model includes a feeding hopper, two feeding channels, a replenishing channel, a replenishing direction control hopper, and a weighing module. The material in the feeding hopper is first fed to two waiting hoppers through the two feeding channels. When it is close to the preset weight, it is replenished to the corresponding waiting hopper through the replenishing direction control hopper. Since the two waiting hoppers count the grains simultaneously, the counting speed is fast and more accurate. Moreover, one replenishing direction control hopper can replenish the two waiting hoppers according to the needs, making the structure simpler.

[0015] 2. The dual-head weighing and packaging machine with lifting function provided by this utility model includes two feeding ports and two feeding port opening and closing components in the feeding port control compartment. The feeding port opening and closing components include a feeding baffle plate and a feeding cylinder for controlling the movement of the feeding baffle plate. In this way, the two feeding port opening and closing components can control the opening or closing of the corresponding feeding ports respectively, thereby controlling the feeding direction.

[0016] 3. The dual-head weighing and packaging machine with lifting mechanism provided by this utility model has a discharge hopper below the two waiting hoppers. The discharge hopper includes a qualified product discharge port, an unqualified product discharge port, and two discharge port opening and closing components. When the weight of the material in the waiting hopper reaches the preset weight, one of the discharge port opening and closing components controls the qualified product discharge port to open. When the feeding speed is too fast, causing the weight of the material in the waiting hopper to exceed the preset weight, the other discharge port opening and closing component controls the unqualified product discharge port to open, thereby discharging the material in the waiting hopper into the material hopper. The material in the material hopper is then transferred to the feeding hopper through the transfer hopper, and the above cycle is repeated to ensure accurate material quantity.

[0031] Example

[0032] This embodiment provides a dual-head weighing and packaging machine with an enhanced design, such as... Figure 1 , Figure 2 and Figure 7 As shown, it includes a frame 1, a feed bin 2, two feeding channels 3, a replenishment channel 5, two weighing modules 7, a discharge bin 14, and a transfer bin 20.

[0033] The feed hopper 2, located at the top of the frame 1, is used to store and convey materials. For example... Figure 2 As shown, the discharge port of the feed hopper 2 is provided with a first baffle plate 11 corresponding to the two feeding channels 3 and the replenishing channel 5. The three first baffle plates 11 can be raised or lowered to control the feeding speed to the two feeding channels 3 and the replenishing channel 5.

[0034] like Figure 2As shown, two feeding channels 3 arranged side by side are located below the feeding bin 2, which are suitable for receiving the materials in the feeding bin 2 and conveying them to the corresponding waiting bin 4.

[0035] The feeding channel 5 is located between the two feeding channels 3, such as... Figure 2 As shown, a feeding direction control chamber 6 is provided at the end of the feeding channel 5. The feeding direction control chamber 6 is used to feed materials to the corresponding waiting chamber 4. In this embodiment, as... Figure 3 and Figure 4 As shown, the feeding direction control chamber 6 includes: two feeding ports 8, corresponding to the corresponding waiting chambers 4; and two feeding port opening and closing components, which respectively control the opening or closing of the corresponding feeding ports 8. Each feeding port opening and closing component includes a feeding baffle 9 and a feeding cylinder 10 for controlling the movement of the feeding baffle 9. It should be noted that, as... Figure 2 As shown, vertical vibrators are installed below the two feeding channels 3 and the replenishing channel 5. During feeding, the material in the feeding hopper is first fed to the two waiting hoppers 4 through the two feeding channels 3. When the material is close to the preset weight, the vertical vibrators below the two feeding channels 3 are controlled to stop working, and the first baffle plate 11 corresponding to the two feeding channels 3 is closed. Then, the material is replenished to the corresponding waiting hopper 4 through the replenishing channel 5 and the replenishing direction control hopper 6.

[0036] Material storage bin 4, such as Figure 4 As shown, it is equipped with a second baffle plate 12 for controlling the opening and closing of its discharge port, and a second cylinder 13 for controlling the movement of the second baffle plate 12. The top of the second baffle plate 12 is hinged to the waiting bin 4. A weighing module 7 is provided below the waiting bin 4 for weighing the material in the waiting bin 4.

[0037] The discharge hopper 14 is located below the two receiving hoppers 4. Figure 5 and Figure 6 As shown, the discharge bin 14 includes: a qualified product discharge port 15 and an unqualified product discharge port 16, which are respectively disposed on both sides of the discharge bin 14. The unqualified product discharge port 16 is correspondingly disposed with the material bin 17. Two discharge port opening and closing components control the opening or closing of the corresponding qualified product discharge port 15 and unqualified product discharge port 16. The discharge port opening and closing components include a discharge baffle 18 and a discharge cylinder 19 for controlling the action of the discharge baffle 18. In this embodiment, the main body of the discharge cylinder 19 is fixed on the discharge baffle 18, and the push rod end of the discharge cylinder 19 is fixed on the outer wall of the discharge bin 14.

[0038] Material hopper 17 is used to receive materials from non-conforming product outlet 16 and transfer them to transfer hopper 20, such as... Figure 7 and Figure 8As shown, the material bin 17 is provided with a third baffle plate 23 corresponding to the transfer bin 20 at the discharge port, and a third cylinder 24 for controlling the opening and closing of the third baffle plate 23.

[0039] Transfer bin 20, such as Figure 7 and Figure 8 As shown, the lifting arm 21 is movably mounted on the gantry frame 22. The transfer bin 20 is adapted to receive materials from the material bin 17 and transfer them to the feed bin 2. The power mechanism is connected to the lifting arm 21 and is adapted to drive the lifting arm 21 to move up and down. It should be noted that the lifting arm 21 can be hydraulically, pneumatically, or electrically driven. The above-mentioned driving methods are existing mature technologies, so their specific structures and working principles will not be described in detail. The transfer bin 20 is rotatably mounted on the lifting arm 21. It has an initial position where it is placed horizontally on the lifting arm 21 and an inclined pouring position. The lifting arm 21 is provided with a pouring cylinder 25 located at the bottom of the transfer bin 20. The pouring cylinder 25 drives the transfer bin 20 to switch between the initial position and the pouring position. The discharge port of the transfer bin 20 is provided with a fourth baffle plate 26 and a fourth cylinder 27 for controlling the opening and closing of the fourth baffle plate 26.

[0040] The dual-head weighing and packaging machine provided by this utility model includes a feeding bin 2, two feeding channels 3, a replenishing channel 5, a replenishing direction control bin 6, and a weighing module 7. The material in the feeding bin 2 is first fed to two waiting bins 4 through the two feeding channels 3. When it is close to the preset weight, it is replenished to the corresponding waiting bin 4 through the replenishing direction control bin 6. Since the two waiting bins 4 count the grains simultaneously, the counting speed is fast and more accurate. In addition, one replenishing direction control bin can replenish the two waiting bins as needed, making the structure simpler.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
