Description

Technical Field

[0001] This utility model relates to the field of bagging technology, and more specifically, to a chopsticks bagging device. Background Technology

[0002] In existing chopsticks packaging technology, chopsticks are often only moved to the bag opening by a conveyor belt, and then fall from the bag opening to the bottom of the bag.

[0003] During this process, manual intervention is required to unfold the bag into place, and the chopsticks may pile up disorderly at the bottom of the bag. Disorderly piling of chopsticks may lead to uneven distribution of space inside the packaging bag, reducing the actual capacity of the bag. To achieve the standard quantity, it may be necessary to increase the size of the packaging bag, increasing material costs; or manual intervention may be required to adjust the position of the chopsticks, reducing automation efficiency. Utility Model Content

[0004] In view of this, the present invention provides a chopsticks bagging device, which aims to solve the above-mentioned technical problems.

[0005] This utility model discloses a chopstick bagging device, comprising a conveying assembly of a ring conveyor chain / belt, the ring conveyor chain / belt having a feeding side and a discharging side, and a plurality of material grooves provided on the outer ring surface of the ring conveyor chain / belt. The conveying assembly includes a bag-supporting structure located on the discharging side and a lifting assembly that drives the discharging side of the ring conveyor chain / belt to move within the bag-supporting structure along the Z-axis direction. The conveying assembly also includes a counterweight assembly movably connected to the conveying assembly in the Z-axis direction and movable with the feeding side of the ring conveyor chain / belt. A guide structure is provided between the conveying assembly and the lifting assembly and / or the counterweight assembly. The movement direction of the lifting assembly is opposite to the movement direction of the counterweight assembly, thereby causing the ring conveyor chain / belt to perform telescopic movement.

[0006] In some embodiments of this application, the lifting assembly includes two first lifting plates that are slidably connected to the conveying assembly in the Z-axis direction. The two first lifting plates are connected to a synchronous lifting drive mechanism. The discharge side of the annular conveyor chain / belt is located in the space between the two first lifting plates and is driven to move within the bag support structure by the movement of the first lifting plates.

[0007] In some embodiments of this application, a first shaft is provided between the lower ends of the two first lifting plates, and a first rotating member that meshes with the annular conveyor chain / belt is provided on the first shaft.

[0008] In some embodiments of this application, the synchronous lifting drive mechanism is any one of a gear and rack drive mechanism and a linear drive structure, and a guide structure is provided between the first lifting plate and the transmission component.

[0009] In some embodiments of this application, the synchronous lifting drive mechanism includes a rack fixedly mounted on the first lifting plate, a drive gear meshing with the corresponding rack on the transmission assembly, the two drive gears rotating synchronously through a synchronous transmission structure, and one of the drive gears being connected to a first drive motor.

[0010] In some embodiments of this application, the travel distance of the counterweight assembly in the Z-axis direction is greater than the travel distance of the discharge side of the annular conveyor chain / belt along the Z-axis direction.

[0011] In some embodiments of this application, the counterweight assembly includes two counterweight plates that are slidably connected to the conveying assembly in the Z-axis direction. At least a portion of the feeding side of the annular conveyor chain / belt is located in the space formed between the two counterweight plates. A second shaft is provided between the two counterweight plates, and a second rotating member that meshes with the annular conveyor chain / belt is provided on the second shaft.

[0012] In some embodiments of this application, the bag support structure includes two cantilever bag support rods with one end fixed to the conveying assembly.

[0013] In some embodiments of this application, the feeding side of the annular conveyor chain / belt is inclined, the discharging side of the annular conveyor chain / belt is vertical, the conveying assembly includes a bottom support leg, and two side baffles are provided on the bottom support leg. The two side baffles are connected by a reinforcing member, and a second drive motor for the movement of the annular conveyor chain / belt is formed between the two side baffles.

[0014] In some embodiments of this application, the counterweight assembly further includes a second reinforcing member disposed between and connected to the two counterweight plates.

[0015] Compared with existing technologies, the advantages of this invention lie in the fact that by setting several material troughs on the annular conveyor chain / belt of the conveying component to convey materials, and by using a lifting component to move the discharge side of the annular conveyor chain / belt along the Z-axis within the bag-supporting structure, orderly accumulation of materials is achieved during the bagging process. At the start of bagging, the lifting component drives the discharge side of the annular conveyor chain / belt to extend into the bottom of the bag in the bag-supporting structure, reserving a height difference for material stacking. After bagging begins, the lifting component drives the discharge side of the annular conveyor chain / belt to gradually move upwards along the Z-axis, with the moving speed matching the material stacking speed. This prevents the material inside the bag from contacting the annular conveyor chain / belt and affecting the stacking, thus achieving orderly accumulation of materials during bagging. Simultaneously, as the lifting component moves along the Z-axis, the counterweight component moves in the opposite direction, ensuring that the discharge side of the annular conveyor chain / belt remains taut even during extension and retraction, enabling continuous operation of the material bagging process. Compared with existing technologies, this invention enables chopsticks to be packaged in an orderly manner, reducing the need for manual intervention. The entire packaging process can be carried out more smoothly according to the automated process, greatly improving production efficiency and making the production process more efficient and stable.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] Combination Figure 1-5As shown, this embodiment provides a chopsticks bagging device, including a conveying assembly with an annular conveyor chain / belt 11. The annular conveyor chain / belt 11 is, for example, an annular conveyor chain or an annular synchronous conveyor belt. In this embodiment, multiple annular conveyor chains / belts 11 are arranged in parallel and move synchronously. The annular conveyor chain / belt 11 has a feeding side and a discharging side, and a plurality of material grooves (not shown in the figure) are provided on the outer annular surface of the annular conveyor chain / belt 11. For example, blocks are added to the links of the annular conveyor chain and distributed at acute angles to the links, and two adjacent blocks form material grooves. The conveying assembly is provided with a bag-supporting structure located on the discharging side and a lifting assembly that drives the discharging side of the annular conveyor chain / belt 11 to move along the Z-axis direction within the bag-supporting structure. The conveying assembly is also provided with a counterweight assembly that is movably connected to the conveying assembly in the Z-axis direction and moves with the feeding side of the annular conveyor chain / belt 11. A guide structure is provided between the conveying assembly and the lifting assembly and / or the counterweight assembly. The movement direction of the lifting assembly is opposite to the movement direction of the counterweight assembly, thereby causing the annular conveyor chain / belt 11 to perform telescopic movement.

[0028] Specifically, the lifting assembly drives the discharge side of the annular conveyor chain / belt 11 to move upward in the Z-axis direction, which can be uniform motion or intermittent motion.

[0029] It is understood that in this embodiment, the discharge side of the annular conveyor chain / belt 11 is driven by the lifting component to move along the Z-axis direction within the bag-supporting structure. When moving downward along the Z-axis, the discharge side of the annular conveyor chain / belt can fully open the bag 6 to prevent the bag from not being fully opened or to require manual assistance in opening the bag. When moving upward along the Z-axis, the annular conveyor chain / belt 11 moves at a uniform speed or intermittently, which can stably feed the material into the bag 6, achieving efficient bagging of the material.

[0030] It is understood that in this embodiment, the chopsticks bagging device feeds the material through the feeding side of the annular conveyor chain / belt 11 and places the material in the material trough. The annular conveyor chain / belt 11 is then activated to transport the material to the discharge side. The discharge side transports the material to the bottom of the bag 6 on the bag-supporting structure and allows it to accumulate. After the material begins to accumulate at the bottom of the bag, the lifting assembly drives the discharge side of the annular conveyor chain / belt 11 to move upwards along the Z-axis, allowing the material to accumulate layer by layer at the bottom of the bag until bagging is complete. After the lifting assembly drives the discharge side of the annular conveyor chain / belt 11 to begin moving along the Z-axis, the annular conveyor chain / belt 11 extends and retracts. At this time, the counterweight assembly moves in the opposite direction to the discharge side of the annular conveyor chain / belt 11, ensuring that the annular conveyor chain / belt 11 remains taut during the extension and retraction process, preventing material from falling and affecting bagging.

[0031] Understandably, this embodiment enables the orderly packaging of chopsticks, reduces the need for manual intervention, and allows the entire packaging process to proceed more smoothly according to the automated process, greatly improving production efficiency and making the production process more efficient and stable.

[0032] In one specific embodiment of this application, the lifting assembly includes two first lifting plates 21 that are slidably connected to the conveying assembly in the Z-axis direction. The two first lifting plates 21 are connected to a synchronous lifting drive mechanism. The discharge side of the annular conveyor chain / belt 11 is located in the space between the two first lifting plates 21 and the movement of the first lifting plates 21 drives the discharge side of the annular conveyor chain / belt 11 to move within the bag support structure.

[0033] In one specific embodiment of this application, a first shaft 23 is provided between the lower ends of the two first lifting plates 21, and a first rotating component 24 that meshes with the annular conveyor chain / belt 11 is provided on the first shaft 23. The first rotating component 24 is, for example, a sprocket or a synchronous belt pulley.

[0034] Specifically, in this embodiment, the discharge side of the annular conveyor chain / belt 11 is located in the space between the two first lifting plates 21, and the lower ends of the two first lifting plates 21 are connected by a first shaft 23, thereby achieving synchronous movement of the two lifting plates. Simultaneously, the first rotating component 24 on the first shaft 23 meshes with the annular conveyor chain / belt 11, enabling synchronous movement of the annular conveyor chain / belt 11 and the two first lifting plates 21. The synchronous lifting drive mechanism drives the discharge side of the annular conveyor chain / belt 11 to move synchronously while simultaneously driving the two first lifting plates 21, thus enabling the material to be directly bagged at the bottom of the bag 6 during the bagging operation. Furthermore, as the material accumulates at the bottom of the bag, the discharge side can gradually adjust the discharge height to avoid disorderly accumulation of the material.

[0035] In one specific embodiment of this application, the synchronous lifting drive mechanism is either a gear and rack 25 drive mechanism or a linear driver structure, and a guide structure is provided between the first lifting plate 21 and the transmission component.

[0036] It is understood that any structural component capable of achieving the driving purpose can serve as the synchronous lifting drive mechanism in this embodiment. The synchronous lifting drive mechanism can be selected according to the actual situation, and this embodiment does not make any specific limitations on it.

[0037] Specifically, in this embodiment, the guide structure is preferably a guide rail 71 and a slider 72 arranged along the Z-axis direction. Either the guide rail 71 or the slider 72 is arranged on the side wall of the first lifting plate 21 opposite to the conveying component, and the other is arranged on the side wall of the side baffle 13 of the conveying component opposite to the first lifting plate 21.

[0038] It is understandable that the guide structure in this embodiment avoids the possible offset of the first lifting plate 21 and the discharge side of the conveying component when they move along the Z-axis, thereby improving the accuracy of the bagging position, which is conducive to standardized production and improves work efficiency.

[0039] In one specific embodiment of this application, the synchronous lifting drive mechanism includes a rack 25 fixedly disposed on the first lifting plate 21, a drive gear 26 meshing with the corresponding rack 25 on the transmission assembly, the two drive gears 26 rotating synchronously through the synchronous transmission structure 27, and one of the drive gears 26 being connected to the first drive motor 22.

[0040] Specifically, the synchronous transmission mechanism in this embodiment is preferably a transmission chain / belt, but this embodiment does not impose any specific limitations on it.

[0041] Specifically, in this embodiment, the first drive motor 22 is preferably a servo motor.

[0042] It is understood that in this embodiment, the synchronous lifting drive mechanism drives one of the drive gears 26 to rotate, and the synchronous transmission mechanism realizes the synchronous rotation of the two drive gears 26, thereby driving the rack 25 and the first lifting plate 21 that mesh with the two drive gears 26 to move along the Z-axis.

[0043] In one specific embodiment of this application, the travel distance of the counterweight component in the Z-axis direction is greater than the travel distance of the discharge side of the annular conveyor chain / belt 11 along the Z-axis direction.

[0044] In one specific embodiment of this application, the counterweight assembly includes two counterweight plates 31 that are slidably connected to the conveying assembly in the Z-axis direction. At least a portion of the feeding side of the annular conveyor chain / belt 11 is located within the space formed between the two counterweight plates 31. A second shaft 32 is provided between the two counterweight plates 31, and a second rotating member 33 that meshes with the annular conveyor chain / belt 11 is provided on the second shaft 32. The second rotating member 33 is, for example, a sprocket or a synchronous pulley.

[0045] Specifically, in this embodiment, a second shaft 32 is provided between the two counterweight plates 31. A second rotating component 33 is provided on the second shaft 32 to mesh with the annular conveyor chain / belt 11. When the annular conveyor chain / belt 11 is started, at least a portion of the annular conveyor chain / belt 11 on the feeding side runs between the two counterweight plates 31. At the same time, the counterweight assembly and the lifting assembly cooperate with each other. When the lifting assembly drives the discharge side of the annular conveyor chain / belt 11 to reciprocate in the Z-axis direction, the length of the discharge side of the annular conveyor chain / belt 11 in the Z-axis direction changes, which in turn causes the length of the feeding side of the annular conveyor chain / belt 11 to change. At this time, the counterweight assembly moves in the opposite direction to the discharge side of the annular conveyor chain / belt 11, so that the annular conveyor chain / belt 11 always remains in a taut state, preventing material from falling off.

[0046] Specifically, in this embodiment, a guide structure is also provided between the counterweight assembly and the conveying assembly. The guide structure is preferably a guide rail 71 and a slider 72. Either the guide rail 71 or the slider 72 is provided on the side wall of the counterweight plate 31 opposite to the annular conveyor chain / strip, and the other is provided on the side wall of the side baffle 13 of the conveying assembly opposite to the counterweight plate 31.

[0047] It is understood that in this embodiment, the lifting and lowering motion of the discharge side of the annular conveyor chain / belt 11 during operation is achieved by setting a counterweight component in conjunction with the lifting component, thereby realizing orderly material accumulation and improving work efficiency.

[0048] In one specific embodiment of this application, the bag-supporting structure includes two cantilever bag-supporting rods 41, one end of which is fixed to the conveying assembly. The cantilever bag-supporting rods 41 can improve the utilization of the space below them.

[0049] In one specific embodiment of this application, the feeding side of the annular conveyor chain / belt 11 is inclined, and the discharging side is vertical. The conveying assembly includes a bottom support 12, on which two lateral baffles 13 are provided. The two lateral baffles 13 are connected by a reinforcing member 14, and a second drive motor 15 for moving the annular conveyor chain / belt 11 is formed between the two lateral baffles. The second drive motor 15 outputs power through a transmission shaft fixed between the two lateral baffles 13, and a third rotating component that meshes with the annular conveyor chain / belt 11 is provided on the transmission shaft. The third rotating component is, for example, a sprocket or a synchronous pulley. The number of third rotating components is equal to the number of annular conveyor chains / belts 11, and they mesh one-to-one.

[0050] Specifically, in this embodiment, the second drive motor 15 is preferably a servo motor.

[0051] It is understood that, in this embodiment, a side baffle 13 is provided on the bottom support 12 of the conveying assembly, and a second drive motor 15 is provided between the two side baffles 13 to drive the circular conveyor chain / belt 11 to move. At the same time, the side baffles are connected by reinforcing members 14 to ensure the stability of the conveying assembly during operation.

[0052] In some embodiments of this application, the counterweight assembly further includes a second reinforcing member disposed between and connected to the two counterweight plates 31.

[0053] Specifically, in this embodiment, the two counterweight plates 31 of the counterweight assembly are also connected by a second reinforcing member, which further improves the stability of the transmission assembly during operation.

[0054] Specifically, this embodiment also includes a controller 5, which is electrically connected to the first drive motor 22 and the second drive motor 15, respectively, and is used to control the operation of the first drive motor 22 and the second drive motor 15.

[0055] It will be understood by those skilled in the art that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
