[0001] This utility model relates to the field of metering and packaging device technology, and in particular to an automatic metering and packaging device for materials. Background Technology

[0002] In modern industrial production, material measurement and packaging are crucial steps in the production process. Traditional manual measurement and packaging methods are not only inefficient and labor-intensive, but also lack accuracy, easily leading to inconsistencies in packaged weights. With the continuous development of industrial automation technology, automated material measurement and packaging devices have emerged. These devices enable rapid and accurate measurement and packaging of materials, significantly improving production efficiency and product quality while reducing production costs.

[0003] In existing technologies, when feeding materials into packaging bags in traditional automatic metering and packaging devices, the bottom of the feeding mechanism is usually designed to be small because some packaging bags have small openings. Therefore, when materials fall into the device, the feeding mechanism may become blocked, which will increase the working time of the staff and reduce the feeding efficiency. Utility Model Content

In this way, packaging bags of different sizes can be fixed. Attached Figure Description

[0020] 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.

[0021] 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.

[0022] Example 1, such as Figures 1-4 As shown, this utility model provides an automatic material metering and packaging device, including a support frame 1. A second support plate 7 is fixedly installed on the outer wall of the support frame 1. An electric telescopic rod 8 is fixedly installed on the top of the second support plate 7. The telescopic end of the electric telescopic rod 8 passes through the second support plate 7 and is fixedly installed with a placement frame 9. A fixed frame 15 is fixedly installed at the bottom of the placement frame 9. A feeding hopper 14 is fixedly installed on the inner wall of the fixed frame 15. A storage frame 16 is fixedly installed at the bottom of the fixed frame 15. Two movable plates 18 are arranged inside the storage frame 16. A first spring 17 is fixedly installed on both sides of the outer side of the movable plate 18. One end of the first spring 17 is fixedly connected to the inner wall of the storage frame 16. A limit rod is fixedly installed on one end of the movable plate 18. One end of the limit rod is slidably inserted into the inner wall of the storage frame 16. Two rubber rods 19 are fixedly installed between the two movable plates 18. A connecting block 20 is fixedly installed on the outer wall of one of the two movable plates 18. A first motor 21 is fixedly installed on the outer wall of the storage frame 16. The output end of the first motor 21 enters the storage frame 16 and is fixedly installed with a cam 22.

[0023] The effect achieved by the entire embodiment 1 is as follows: during feeding, the operator starts the electric telescopic rod 8, the feeding hopper 14 descends, and the bottom of the feeding hopper 14 moves to the opening of the packaging bag. Then, the operator starts the first motor 21. The output end of the first motor 21 drives the cam 22 to rotate. When the cam 22 contacts the connecting block 20, it pushes the connecting block 20 to move, which in turn drives the moving plate 18 and the rubber rod 19 to move. The rubber rod 19 contacts the outer wall of the feeding hopper 14 and impacts the feeding hopper 14. This can speed up the discharge efficiency of the feeding hopper 14. When the cam 22 no longer contacts the connecting block 20, the first spring 17 drives the rubber rod 19 to reset. This back-and-forth motion improves the discharge efficiency and reduces the probability of blockage.

[0024] Example 2, as Figures 1-4 As shown, further, a fixing plate 2 is fixedly installed on the outer wall of the support frame 1, and a second motor 25 is fixedly installed at the bottom of the fixing plate 2. The output end of the second motor 25 passes through the fixing plate 2 and is fixedly installed with a second gear 26. A rotating plate 3 is rotatably installed on the outer wall of the support frame 1. A connecting sleeve 23 is fixedly installed at the bottom of the rotating plate 3. A first gear 24 is fixedly installed on the outer wall of the connecting sleeve 23. The first gear 24 meshes with the second gear 26. Four evenly distributed support rods 27 are fixedly installed at the bottom of the rotating plate 3. Universal wheels 28 are provided at the bottom of the support rods 27.

[0025] Furthermore, multiple evenly distributed adjustment plates 4 are fixedly installed on the outer wall of the rotating plate 3. The outer wall of the adjustment plate 4 is provided with a sliding groove 29. A threaded rod 30 is rotatably installed inside the sliding groove 29. A third motor 31 is fixedly installed on the outer wall of the adjustment plate 4. The output end of the third motor 31 is fixedly connected to one end of the threaded rod 30. Two sliding plates 32 are threadedly connected to the outer wall of the threaded rod 30.

[0026] Furthermore, a storage plate 33 is fixedly installed on the opposite side of each of the two slide plates 32, and a limit groove 34 is opened on the opposite side of each of the two slide plates 32. An electromagnet 35 is fixedly installed on the inner side wall of the limit groove 34, a second spring 36 is fixedly installed on one end of the electromagnet 35, an iron plate 37 is fixedly installed on one end of the second spring 36, and a clamping plate 38 is fixedly installed on one end of the iron plate 37.

[0027] Furthermore, a storage bin 11 is slidably installed inside the placement frame 9, a measuring plate 12 is fixedly installed on the outer wall of the storage bin 11, a weighing sensor 10 is fixedly installed on the top of the placement frame 9, and a solenoid valve 13 is provided on the outer wall of the storage bin 11.

[0028] Furthermore, a first support plate 5 is fixedly installed on the outer wall of the support frame 1, and a sealing device 6 is provided at the bottom of the first support plate 5. When the packaging bag moves below the sealing device 6, the sealing device 6 can seal the packaging bag.

[0029] Furthermore, the threaded rod 30 is provided with two sections of threads with opposite textures. The threaded rod 30 is connected to two slide plates 32 respectively through the two sections of threads with opposite textures. When the threaded rod 30 rotates, the two slide plates 32 move closer to each other or further away from each other.

[0030] The effect achieved by the entire embodiment 2 is as follows: when fixing the packaging bag, the worker activates the electromagnet 35, the iron plate 37 is attracted and moves towards the electromagnet 35, the second spring 36 is compressed, and then the packaging bag moves between the two sliding plates 32. Then the third motor 31 is activated, the threaded rod 30 rotates, and thus drives the two sliding plates 32 to move closer to each other until the two ends of the packaging bag contact the two sides of the sliding plates 32 respectively. Then the electromagnet 35 is turned off, and the elastic force of the second spring 36 pushes the iron plate 37 to move, so that both ends of the packaging bag are clamped by the storage plate 33 and the clamping plate 38. In this way, packaging bags of different sizes can be fixed.

[0031] Working principle: When fixing the packaging bag, the operator activates the electromagnet 35, and the iron plate 37 moves towards the electromagnet 35 under the attraction. The second spring 36 is compressed, and the packaging bag moves between the two sliding plates 32. Then, the third motor 31 is activated, and the threaded rod 30 rotates, which in turn drives the two sliding plates 32 to move closer to each other until both ends of the packaging bag contact the sides of the sliding plates 32. Then, the electromagnet 35 is turned off, and the elastic force of the second spring 36 pushes the iron plate 37 to move, so that both ends of the packaging bag are clamped by the storage plate 33 and the clamping plate 38. This can fix packaging bags of different sizes. Then, the operator activates the second motor 25, and the second gear 26 rotates, which drives the first gear 24 to rotate, which in turn drives the rotating plate 3 and the packaging bag to rotate. When the packaging bag moves to the bottom of the feeding hopper 14, the operator activates the solenoid valve 13, and the material inside the storage bin 11 enters the feeding hopper 14. When the weight of the storage bin 11 and the original material inside minus the weight detected by the weighing sensor 10 equals the required weight, the solenoid valve 13 closes. During feeding, the operator activates the electric telescopic rod 8, causing the feeding hopper 14 to descend and move its bottom to the opening of the packaging bag. Then, the operator activates the first motor 21, whose output drives the cam 22 to rotate. When the cam 22 contacts the connecting block 20, it pushes the connecting block 20 to move, which in turn drives the moving plate 18 and the rubber rod 19 to move. The rubber rod 19 contacts the outer wall of the feeding hopper 14, impacting it and thus accelerating the discharge efficiency of the feeding hopper 14. When the cam 22 no longer contacts the connecting block 20, the first spring 17 drives the rubber rod 19 to reset. This back-and-forth motion improves the discharge efficiency and reduces the probability of blockage.

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.
