Description

Technical Field

[0001] This utility model relates to the field of precise metering feeding equipment, and more particularly to an automatic packaging feeding equipment with precise metering. Background Technology

[0002] Precise metering automatic packaging and feeding equipment is a core component of modern automated packaging production lines. Its main function is to accurately and quickly dispense bulk materials (such as granules, powders, tablets, etc.) from storage bins according to preset weight values ​​and transport them to subsequent packaging processes.

[0003] Currently, most automatic packaging and feeding equipment on the market uses a combination of gravity-based feeding and weighing sensors for metering. Its typical structure is as follows: materials are stored in a top storage bin, and the feeding flow is controlled by a solenoid valve or vibrating feeder, causing the material to fall onto a conveyor belt below for feeding.

[0004] Existing technologies have revealed problems in practical applications: the unloading process after weighing is uncontrollable, easily generating splashes and dust, and leaving significant material residue, leading to unstable metering accuracy; material residue and bridging are common problems in storage silos. For materials with poor flowability, high viscosity, or susceptibility to moisture, the material easily adheres to and accumulates at the corners, bottom plate, or outlet of the storage silo, even forming bridging blockages. Therefore, it is necessary to develop an accurate metering automatic packaging and feeding device to address the pain points of existing technologies. Utility Model Content

[0033] Reference Figure 1-5This utility model provides an embodiment of an automatic packaging and feeding device for precise measurement, comprising a conveyor belt 1 and a support frame 2. The conveyor belt 1 can smoothly transport and feed materials and can be stably placed on the ground by the support feet at both ends. Support frames 3 are fixedly connected to both ends of the support frame 2, and storage bins 17 are fixedly connected to the top of each support frame 3, into which materials can be poured uniformly. A weighing frame 4 is rotatably connected through the top of the support frames 3, and a connecting column 5 is rotatably connected through the bottom of the support frames 3. Both ends of the ring are connected to a first rotating block 6. A first cylinder 7 is fixedly connected to one side of each first rotating block 6. A fixed post 8 is fixedly connected to the output end of each first cylinder 7. A first spring 9 is fixedly connected to one end of each fixed post 8. A second rotating block 10 is fixedly connected to one end of each first spring 9. The second rotating block 10 is connected to both ends of the weighing frame 4 through and rotatably. When the first cylinder 7 retracts, it causes the weighing frame 4 to rotate downwards; when the first cylinder 7 extends, it causes the weighing frame 4 to rotate upwards, causing the bottom wall of the weighing frame 4 to contact the bottom of the baffle 15, thus facilitating the weighing... The weighing frame 4 cannot be flipped upwards; at this time, the weighing frame 4 is horizontal, and the baffle 15 can block the material inside the frame. The first spring 9 is compressed. When the first cylinder 7 extends or retracts to its limit, the first motor 11 is fixedly connected to one side of the support frame 2, and the output end of the first motor 11 is fixedly connected to the cam 12. When the weighing frame 4 is tilted to a suitable angle, the material inside the frame slides down onto the conveyor belt 1 under the action of gravity. At this time, the first motor 11 can be started to make the cam 12 rotate, which, together with the first spring 9, can make the weighing frame 4 vibrate. The baffle 15 is fixedly connected to the top of the support frame 2. When the first cylinder 7 extends, it can drive the weighing frame 4 to rotate upward so that the bottom wall of the weighing frame 4 contacts the bottom of the baffle 15, preventing the weighing frame 4 from flipping upward. At this time, the weighing frame 4 is horizontal, and the baffle 15 can block the material in the frame. The first spring 9 is compressed. When the first cylinder 7 extends to its limit, the first spring 9 is also in a compressed state. At this time, the weighing frame 4 will not tilt even if there is material in the frame. The bottom wall of the weighing frame 4 is fixedly connected to the pressure sensor 13. The pressure sensor 13 is equipped with a weighing component on its top. Storage components are provided at both ends of the storage bin 17.

[0034] The weighing assembly includes a weighing plate 14, the bottom of which is fixedly connected to a pressure sensor 13. A control console 16 is fixedly connected to one side of the front support frame 3. The pressure sensor 13 is electrically connected to the control console 16. After the material falls onto the weighing plate 14, it can be accurately weighed in conjunction with the pressure sensor 13. The storage assembly includes a fixing plate 18, one side of which is fixedly connected to a storage bin 17. The bottom wall of the storage bin 17 has a discharge port, and the discharge port is equipped with a filter screen to slow down the discharge speed. A bidirectional threaded rod 22 is rotatably connected through the fixing plates 18 on the right side. The left fixing plate... A guide post 19 is fixedly connected through and fixed between the two sides of the storage bin 17. A second motor 23 is fixedly connected to one end of the right rear end fixing plate 18. A support platform is provided at the bottom of the second motor 23, which is fixed on the storage bin 17 and can support the second motor 23. The output end of the second motor 23 is fixedly connected to the bidirectional threaded rod 22. Slider 20s are slidably connected through and slidably connected to both ends of the outer ring of the guide post 19. Slider 20s are threadedly connected through and threaded to both ends of the outer ring of the bidirectional threaded rod 22. Nut pairs are provided inside the two sliders 20s on the outer ring of the bidirectional threaded rod 22. A connecting rod is fixedly connected to one side of each slider 20. Block 21 has scrapers 27 slidably connected to both ends of one side of the inner wall of the storage hopper 17. Each scraper 27 has a fixed rod 24 fixedly connected to its top, and each fixed rod 24 has a brush 26 fixedly connected to its bottom center. The scrapers 27 and brushes 26 can push the material towards the discharge port and simultaneously clean the inside of the storage hopper 17. Each fixed rod 24 has a connecting rod 25 fixedly connected to both sides of its bottom. Each connecting rod 25 has a limit hole on one side. The outer wall of the connecting rod 25 is slidably connected to the connecting block 21. Each inner wall of the connecting block 21 has a limit plate 29 slidably connected to one side, and one end of the limit plate 29 is fixedly connected to a limit... One end of the column 28 is connected to the connecting rod 25 and slides through it. The other end of the limiting plate 29 is fixedly connected to the second spring 30. One end of the second spring 30 is fixedly connected to the connecting block 21. Pressing the limiting column 28 inward will release the limitation on the fixed rod 24 by completely disengaging the limiting column 28 from the limiting hole. The top of the other end of the front support frame 3 is fixedly connected to the second cylinder 32. The output end of the second cylinder 32 is fixedly connected to the sliding plate 31. The top of the sliding plate 31 is slidably connected to the bottom of the storage bin 17. The sliding plate 31 can block the discharge port to control the material discharge.

[0035] Working principle: The materials to be packaged are poured into the storage silo 17. At the same time, the required weighing parameters of the materials are preset through the control console 16. The second cylinder 32 is in the extended state, which drives the sliding plate 31 to fit against the bottom of the storage silo 17, blocking the discharge port and preventing the materials from falling prematurely. When it is necessary to feed materials to the weighing frame 4, the second cylinder 32 is triggered to retract through the control console 16. The sliding plate 31 slides away from the discharge port, opening the discharge port of the storage silo 17. The second motor 23 is started, and its output end drives the bidirectional threaded rod 22 to rotate. Since the sliders 20 at both ends of the outer ring of the bidirectional threaded rod 22 are equipped with nut pairs, and the left guide post 19 guides and limits the sliders 20, when the bidirectional threaded rod 22 rotates, the two sliders 20 move towards each other along the guide post 19. The sliders 20 drive the connecting rod 25 to move through the connecting block 21. The fixed rod 24 simultaneously drives the scraper 27 and the brush 26 to slide towards the discharge port of the storage silo 17. The scraper 27 pushes the material in the storage bin 17 toward the discharge port, while the brush 26 cleans the inner wall of the storage bin 17 at the same time to prevent material residue or clumping. After the material is slowed down by the filter screen, it falls evenly onto the weighing plate 14 in the weighing frame 4. After the material falls onto the weighing plate 14, the weighing plate 14 evenly transmits the weight of the material to the pressure sensor 13 at the bottom. After the weighing is completed, the control console 16 triggers the first cylinder 7 to contract, which drives the weighing frame 4 to rotate downward around the connection point of the support frame 3, and the first spring 9 gradually returns to its original state. When the weighing frame 4 is tilted to a suitable angle, the material inside the frame slides towards the conveyor belt 1 under the action of gravity. If the material is not unloaded smoothly due to its stickiness or shape, the first motor 11 is started, and its output end drives the cam 12 to rotate. The cam 12 periodically contacts the bottom of the weighing frame 4, and with the elastic restoring force of the first spring 9, the weighing frame 4 vibrates slightly, which helps the material to slide completely onto the conveyor belt 1. The conveyor belt 1 is then started to smoothly transport the material to the subsequent packaging process, completing a precise metering automatic packaging and feeding process.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
