Technical Field

[0001] This utility model relates to the field of compound fertilizer packaging technology, specifically a bag clamping device for a compound fertilizer metering and packaging machine. Background Technology

[0002] With the booming development of agricultural production, compound fertilizer, as a high-efficiency fertilizer that provides crops with a variety of nutrients, has seen its market demand continue to rise. As the fertilizer industry becomes more scaled up and more intensive, the production efficiency and packaging quality of compound fertilizer are becoming increasingly critical, directly affecting the timeliness of agricultural supplies and the quality of products in the market.

[0003] For example, CN218967344U discloses a compound fertilizer finished product packaging machine, including a base, a conveyor belt fixedly connected to the top of the base, a support plate fixedly connected to the rear side of the top of the base, a storage box fixedly connected to the top of the front of the support plate, a discharge pipe provided at the bottom of the storage box, a feeding hopper fixedly connected to the top of the storage box, and vertical plates fixedly connected to both sides of the front of the support plate. This utility model, through the cooperation of a base, conveyor belt, support plate, storage box, feeding pipe, feeding hopper, vertical plate, moving plate, spreading plate, electric push rod, side plate, sewing mechanism, positioning plate, protective plate, groove, spring, limiting plate, fixing groove, limiting roller, telescopic rod, and support leg, enables the compound fertilizer finished product packaging machine to limit and protect both sides of the bagged compound fertilizer during bagging, preventing the bagged compound fertilizer from tilting and falling during the transmission process. However, the existing compound fertilizer metering and packaging machine's bagging device has a low degree of automation, relying heavily on manual operation to complete the bag opening and bagging actions. Workers need to repeat this high-intensity, mechanical labor for a long time, which not only results in low labor efficiency and easy fatigue, but also increases the risk of operational errors. Furthermore, the materials, shapes, and sizes of compound fertilizer packaging bags are becoming increasingly diverse, and the existing bagging devices cannot cope flexibly, often resulting in bags not being fully opened, bagging not being smooth, or even bag damage, seriously affecting the continuity and stability of the packaging process. Therefore, it is urgent to design a bag clamping device for a compound fertilizer metering and packaging machine to solve the above problems. Utility Model Content

The center of the moving mechanism 4 is threadedly connected to two sets of relatively moving clamping components 5.

[0023] As a further feature of this invention, two sets of sliding rails 12 are installed parallel to each other on the rear side of the top of the packaging box 1. The top of the two sets of sliding rails 12 is provided with a pushing component 33 for movement. Two sets of fixing blocks 13 are fixed on the front side of the top of the packaging box 1. The two sets of fixing blocks 13 are connected by a sliding rod 14. The adhesive component 2 includes a push-pull rod 21 and a front adhesive plate 22. The rear end of the push-pull rod 21 passes through the front side of the top of the packaging box 1. The rear end of the push-pull rod 21 is fixed at the center of the front end of the front adhesive plate 22. Side sliders 23 are fixed at both ends of the front adhesive plate 22 and move within the inner sliding rail 11. This is beneficial for the rear adhesive plate to quickly open the openings of different packaging bags with the front adhesive plate installed at the front end, which facilitates subsequent bag clamping for filling.

[0024] As a further improvement of this utility model, the drive assembly 32 includes a first servo motor 321 and a drive shaft 323. The first servo motor 321 is mounted on the top of the L-shaped mounting plate 31. A controller 322 is mounted on the front end of the first servo motor 321. The rear end of the first servo motor 321 drives the drive shaft 323 to rotate. The drive shaft 323 rotates within the side plate 325 inserted at the rear end. A gear 324 is fixed at the center of the drive shaft 323. The push assembly 33 includes a rack plate 331 and U-shaped sliders 332. The rack plate 331 is fixed on the bottom rear end of the moving mechanism 4. Two sets of U-shaped sliders 332 are fixed at the center of the rack plate 331. The bottom ends of the two sets of U-shaped sliders 332 slide within the moving slide rail 12. The top end of the gear 324 meshes with the bottom right end of the rack plate 331, which facilitates the moving mechanism and the clamping component to clamp the packaging bag, improving its applicability.

[0025] As a further improvement of this utility model, the moving mechanism 4 includes a U-shaped fixed block 41 and a limiting block 45. A second servo motor 42 is installed at the rear end of the U-shaped fixed block 41. The front end of the second servo motor 42 drives the threaded rod 43 to rotate. The front end of the threaded rod 43 is sleeved on the center of the limiting sleeve 46. The limiting sleeve 46 is installed at the rear end of the limiting block 45. The center of the limiting block 45 is sleeved on the center of the sliding rod 14 and moves.

The single clamping component 5 includes a long cylindrical nut 51 and an L-shaped clamping plate 52. The bottom end of the long cylindrical nut 51 is fixed with the L-shaped clamping plate 52. Both ends of the L-shaped clamping plate 52 pass through the center of the crossbar 44, which is beneficial to improve the smoothness of bagging and improve the continuity and stability of the packaging process.

[0026] Working principle: In use, the user first places the packaging bag inside the packaging box 1, then attaches the top and rear side of the packaging bag to the rear adhesive plate 10. Next, the user pushes the front push-pull rod 21 inwards, pushing the fixed front adhesive plate 22 to the front of the packaging bag. Pulling it back then opens the packaging bag initially. Subsequently, under the operation of the controller 322, the first servo motor 321 is powered on, driving the rear drive shaft 323 to rotate. The rotation of the drive shaft 323 drives the fixed gear 324 to rotate, engaging the top rack plate 331 to move to the left. The rack plate 331 can drive the moving mechanism 4 to move to the center of the top of the packaging box 1 by means of two sets of U-shaped sliders 332 fixed at the top. Then, the second servo motor 42 is powered on to drive the threaded rod 43 at the front end to rotate in the limiting sleeve 46. The rotation of the threaded rod 43 can drive the two sets of long cylindrical nuts 51 inserted in the center thread to move outward relative to each other. When the long cylindrical nuts 51 move, the packaging bag can be clamped at the bottom end of the front adhesive plate 22 and the bottom end of the rear adhesive plate 10 by means of the L-shaped clamping plate 52 at the bottom end. Then, filling can be carried out. The above is the complete working principle of this utility model.
