Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vegetable packaging machines, and in particular relates to a vegetable dehydration packaging device for a bag packaging machine. Background Technology
[0002] When packaging dehydrated vegetables such as carrot granules and chopped green onions, pre-made bag packaging machines are required. These machines are automated industrial packaging equipment manufactured by companies such as Maichi Packaging and Anhui Xinyuan, and are mainly used in the packaging of granular, powdered, and liquid materials in the food, pharmaceutical, and chemical industries. The equipment uses a PLC control system to automatically handle the entire process of pre-made bag picking, filling, and sealing, and is compatible with flat bags, stand-up pouches, and other bag types, as well as packaging materials such as paper-plastic composites and aluminum-plastic composites.
[0003] However, existing dehydrated vegetable packaging machines typically employ vibration or stirring mechanisms to prevent clogging. However, these existing anti-clogging technologies have significant drawbacks: high-frequency vibration causes brittle vegetable particles (such as diced carrots) to break; mechanical stirring mechanisms use rotating stirring paddles inside the funnel to cut or agitate the material and prevent clumping, but material residue easily remains between the paddle and the funnel, resulting in a large amount of waste residue that affects the cleanliness of the feeding funnel. Furthermore, the stirring paddle can also compress the material, causing brittle vegetable particles to break. To address these issues, a vegetable dehydration packaging device for bag packaging machines is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a vegetable dehydration packaging device for a bag packaging machine, thereby solving the problem.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a vegetable dehydration packaging device for a bag packaging machine, comprising a packaging machine body and a funnel. The upper surface of the packaging machine body is equipped with a controller, a sealing device, a bag support, a bag feeder, and a rotatable gripping turntable driven by a drive mechanism. An anti-blocking mechanism is connected to the circumferential side of the funnel. The anti-blocking mechanism includes a rotating shaft and a turntable. The upper end of the rotating shaft is fixedly connected to the turntable, and a torque limiter and a secondary gear are fixedly connected to the circumferential side of the rotating shaft. The upper surface of the packaging machine body is equipped with a slide rail and a mounting plate. A motor is fixedly mounted on one surface of the mounting plate, and the output end of the motor is fixedly connected to… A rotating rod is connected to a main gear at one end. Several connecting plates and several sliding rods are provided inside the slide rail. The upper end of the sliding rod is fixedly connected to the turntable. A spring is fixedly connected to one surface of the connecting plate. Two connecting rods are fixedly connected between the turntable and the funnel. The motor drives the funnel to rotate through the meshing of the main gear and the auxiliary gear. When the funnel is blocked, the material cannot be discharged smoothly. The rotating shaft needs a larger torque to drive the funnel to rotate. At this time, the torque limiter cuts off the power transmission between the motor and the funnel. The funnel continues to rotate under the action of inertia, destroying the bridging and thus preventing blockage.
[0006] Preferably, a spiral strip is fixedly connected to the inner wall of the funnel. When the material passes through the spiral strip, it rotates downwards in a spiral. The spiral strip rotates with the funnel, generating centrifugal force, which forces the material to fall along a fixed path, avoiding disorderly accumulation and bridging. In addition, during the rotation, the friction between the material and the air generates a low-pressure vortex, which rolls the adhering debris away from the inner wall, cleaning the inner wall of the funnel.
[0007] Preferably, the main gear and the auxiliary gear are arranged perpendicularly, and the main gear and the auxiliary gear mesh.
[0008] Preferably, the rotating rod is rotatably connected to the mounting plate, and the rotating shaft is rotatably connected to the packaging machine body.
[0009] Preferably, the slide rail is arranged in a ring shape, and the slide rod slides in conjunction with the slide rail.
[0010] Preferably, the inner wall of the slide rail is provided with a plurality of ball grooves, and balls are rolled in the ball grooves.
[0011] This utility model has the following beneficial effects: This invention has the function of preventing material blockage in the feeding hopper. Specifically, it is achieved by setting a torque limiter and a sliding rod. The motor drives the rotating shaft to rotate the turntable through the meshing of gears, which in turn drives the hopper to rotate. When the hopper becomes blocked, the feeding resistance increases sharply, and the motor needs to output more torque to maintain the rotation of the hopper. This causes the torque of the rotating shaft to exceed the set threshold of the torque limiter. The torque limiter cuts off the power transmission path, and the hopper continues to rotate due to inertia. At the same time, the sliding block slides in the annular guide rail, which breaks the material bridging and triggers the anti-blocking action to achieve the anti-blocking function. This invention has the function of cleaning the inner wall of the feeding hopper, avoiding a large amount of debris from being loaded into the feeding hopper. Specifically, it is achieved by setting a spiral strip. When the material falls into the hopper, the falling material drives the surrounding air to flow. When the airflow encounters the spiral strip, it adheres to the spiral surface and flows (due to the viscosity of the fluid), generating a continuous spiral downward airflow field, which can clean the vegetable debris adhering to the inner wall of the hopper.
[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0018] Please see Figures 1-5 As shown, this utility model is a vegetable dehydration packaging device for a bag packaging machine, including a packaging machine body 1 and a funnel 7. The upper surface of the packaging machine body 1 is equipped with a controller 6, a sealer 5, a bag expander 4, a bag feeder 2, and a rotatable gripping turntable 3 driven by a drive mechanism. The circumferential side of the funnel 7 is connected to an anti-blocking mechanism. The vacuum suction cup or mechanical gripper of the bag feeder 2 accurately picks up pre-made empty bags from the bag magazine. The bag expander 4 (such as grippers or airflow) opens the bag opening. At the same time, the detection device ensures that the bag is opened in place. The gripping turntable 3 drives the packaging bag to rotate, so that the packaging bag is directly below the funnel 7. After being metered, the dehydrated vegetables are accurately put into the bag through the funnel 7. The sealer 5 (electric heating block or pulse type) presses and seals the bag opening. Vacuuming or nitrogen filling functions are optional. Finally, the finished bag is sent out by a conveyor belt and counted or coded. The anti-blocking mechanism includes a rotating shaft 17 and a turntable 10. The upper end of the rotating shaft 17 is fixedly connected to the turntable 10. A torque limiter 16 and a secondary gear 20 are fixedly connected to the circumferential side of the rotating shaft 17. The torque limiter 16 monitors the torque of the rotating shaft in real time through a built-in friction plate or ball bearing structure. When the material bridges or clumps in the hopper, the feeding resistance increases sharply. The motor 9 needs to output more torque to maintain the rotation of the hopper, which causes the torque of the rotating shaft 17 to exceed the set threshold of the torque limiter 16. When the torque exceeds the threshold, the friction plate slips, cutting off the power transmission path. The upper surface of the packaging machine body 1 is provided with a slide rail 21 and a mounting plate 8. The slide rail 21 is arranged in a ring shape. Several connecting plates 12 and several slide rods 14 are provided inside the slide rail 21. The slide rods 14 slide in conjunction with the slide rail 21. Several ball grooves are opened on the circumferential side of the inner wall of the slide rail 21. Balls 22 are rolled in the ball grooves. The slide rods 14 slide in the slide rail 21 to limit and guide the rotation of the funnel 7. The balls 22 can reduce the friction between the slide rods 14 and the slide rail 21, so that the slide rods 14 can slide more smoothly in the slide rail 21. A motor 9 is fixedly mounted on one surface of the mounting plate 8. The output end of the motor 9 is fixedly connected to a rotating rod 18, which is rotatably connected to the mounting plate 8. The rotating shaft 17 is rotatably connected to the packaging machine body 1. The output end of the motor 9 is fixedly connected to the rotating rod 18, and one end of the rotating rod 18 is fixedly connected to a main gear 19. The main gear 19 and the auxiliary gear 20 are arranged perpendicularly and mesh with each other. The meshing between the main gear 19 and the auxiliary gear 20 can reduce speed, so that the motor 9 can drive the rotating shaft 17 to rotate at low speed through the rotating rod 18. Furthermore, due to the setting of the spring 13, when the motor 9 drives the rotating shaft 17 to rotate, it needs to rotate clockwise and counterclockwise, and the rotation angle is less than 180 degrees. The upper end of the slide bar 14 is fixedly connected to the turntable 10. A spring 13 is fixedly connected to one surface of the connecting plate 12. When the torque limiter 16 cuts off the power transmission between the motor 9 and the rotating shaft 17, the funnel 7 will continue to rotate due to inertia. The slide bar 14 also slides in the slide rail 21, compressing the spring 13. The spring 13 can reset the funnel 7 and restore it to its original position. Two connecting rods 11 are fixedly connected between the turntable 10 and the funnel 7. The motor 9 drives the rotating shaft 17 to rotate the funnel 7 through the meshing between the main gear 19 and the secondary gear 20. When the funnel 7 is blocked, the material cannot be discharged smoothly. The rotating shaft 17 needs a larger torque to drive the funnel 7 to rotate. At this time, the torque limiter 16 cuts off the power transmission between the motor 9 and the funnel 7. The funnel 7 continues to rotate under the action of inertia, destroying the bridge and thus preventing blockage.
[0019] A spiral strip 15 is fixedly connected to the inner wall of the funnel 7. When the material passes through the spiral strip 15, it rotates downwards in a spiral. The spiral strip 15 rotates with the funnel 7, generating centrifugal force, which forces the material to fall along a fixed path, avoiding disorderly accumulation and bridging. In addition, during the rotation, the friction between the material and the air generates a low-pressure vortex, which rolls the adhering debris away from the inner wall, cleaning the inner wall of the funnel 7 and preventing vegetable waste from adhering to the inner wall of the funnel 7.
[0020] Working principle: After weighing, dehydrated vegetables (such as diced carrots, potatoes, sweet potatoes, and chopped onions) enter funnel 7. The vacuum suction cup or mechanical gripper of bag feeder 2 precisely picks up pre-made empty bags from the bag magazine. The bag opening is opened by bag expander 4 (such as grippers or airflow), while a detection device ensures the bag is properly opened. The gripping turntable 3 rotates the opened packaging bag, and the sealing device 5 (heating block or pulse type) presses and seals the bag opening. Vacuuming or nitrogen filling functions are optional. Finally, the finished bag is conveyed out by a conveyor belt, and counting or coding is completed. When the dehydrated vegetables enter funnel 7, motor 9, through the meshing of main gear 19 and secondary gear 20, causes the rotating shaft 17 to drive the turntable 10 to rotate. The turntable 10 further drives funnel 7 to rotate through connecting rod 11. Under centrifugal force, the dehydrated vegetables flow to the outlet of funnel 7 and then enter the packaging bag. When funnel 7 becomes blocked... When the material is blocked, the resistance to discharge increases sharply, requiring the shaft 17 to have a larger torque to drive the funnel 7 to rotate. When the torque of the shaft 17 exceeds the set threshold of the torque limiter 16, the friction plate of the torque limiter 16 slips, cutting off the power transmission path. However, the funnel 7 will continue to rotate under the action of inertia, destroying the bridging of the material blockage, thus playing a role in preventing blockage. When the funnel 7 rotates, it will drive the slide rod 14 to slide in the slide rail 21, compressing the spring 13. When the material continues to be discharged, the spring 13 returns to its original position, allowing the funnel 7 to continue working. Furthermore, when the material falls into the funnel 7, it will move in a spiral motion through the spiral strip 15. When the material moves in a spiral motion, the friction between the material and the air generates a low-pressure vortex. Since the vegetables are dehydrated vegetables with low adhesion, the generated vortex can roll the adhering debris away from the inner wall, cleaning the inner wall of the funnel 7.
