[0002] Incomplete nutritional formula foods are a type of special medical purpose formula food, used to meet some of the nutritional needs of specific populations. These products are usually available in canned powder form. In addition to aluminum foil sealing, these powder cans also have plastic composite material lids for sealing. The double sealing ensures good moisture-proof performance and prevents milk powder leakage.

[0003] A search revealed Chinese patent CN216035488U, which discloses a sealing device for filling calcium oxide powder cans. During the filling process, the filling unit is placed sequentially inside a placement trough for sequential sealing. Operators can manually rotate the turntable for easy handling. However, when sealing plastic composite caps, the sealing mechanisms often involve pneumatic or hydraulic pressure application. Before the plastic composite cap is pressed, it moves along with the can to the sealing point. During this process, the cap is prone to tilting and changing position. Direct pressure can easily deform and damage the cap, resulting in poor sealing after sealing. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3This utility model provides a non-full nutrient powder can sealing machine, including a frame 1. A conveyor belt 18 is provided between the inner walls of both sides of the frame 1. A can 19 is conveyed above the conveyor belt 18. A plastic composite material cover is placed on top of the can 19. Two guide frames 4 are bolted to the top of the frame 1. The clamping openings of the two guide frames 4 gradually narrow to guide the can 19 conveyed from the outside. A mounting frame 2 is bolted to the top of the frame 1. A partition plate 8 is bolted between the inner walls of both sides of the mounting frame 2. A cylinder 9 is bolted to the top of the partition plate 8. A connecting plate 10 is bolted to the movable end of the cylinder 9. A mounting plate 12 is slidably connected to the bottom of the connecting plate 10, passing through the connecting plate 10. A spring 11 is fixedly connected between the mounting plate 12 and the connecting plate 10. Clamping components for auxiliary support of the can 19 are provided on both sides of the mounting frame 2. The bottom of the mounting plate 12 is provided with... A secondary pressing assembly for adjusting the position of the plastic composite material cap is provided. In use, the can 19, sealed with aluminum foil, is conveyed from the outside onto the conveyor belt 18. The plastic composite material cap is placed on the can 19, and the conveyor belt 18 is started. The conveyor belt 18 moves the can 19 into the mounting frame 2. The clamping assembly is used to assist in clamping the can 19. The cylinder 9 is started, and the cylinder 9 extends to push the connecting plate 10 and the mounting plate 12 downward. The secondary pressing assembly is used to adjust the position of the plastic composite material cap, thereby ensuring that the position of the plastic composite material cap is correct. Then, the cylinder 9 is started again, thereby compressing and deforming the spring 11 to generate elastic force. This allows pressure to be applied to the plastic composite material cap slowly, avoiding damage to the plastic composite material cap caused by excessive pressure at one time. It also increases the fit between the plastic composite material cap and the can 19, improving the sealing performance of the can 19 after sealing.

[0023] In this invention, the clamping assembly includes an electric push rod 3 fixed to the outer walls of both sides of the mounting frame 2. The movable end of the electric push rod 3 is fixed to a mounting plate 5 by bolts. A clamp 7 passing through the mounting plate 5 is slidably connected to one side of the mounting plate 5, and the clamp 7 and the mounting plate 5 are limited by an elastic component. The two ends of the elastic component are respectively fixed to the clamp 7 and the mounting plate 5. The elastic component can be an arc-shaped elastic plate 6 and an elastic rubber block, preferably an arc-shaped elastic plate 6. The arc-shaped elastic plate 6 is made of an elastic metal material, preferably elastic steel. When the tank 19 moves between the two clamps 7, the same... When the two electric push rods 3 are activated, they push the mounting plate 5 and the clamp 7 towards the middle, thereby clamping the tank 19. As the electric push rods 3 continue to extend, the clamp 7 and the mounting plate 5 will compress the elastic component and generate elastic force, preventing the mounting plate 5 from making direct hard contact with the tank 19 and causing deformation of the tank 19. At the same time, one inclined surface of the clamp 7 will squeeze the tank 19, causing the tank 19 to move onto the clamp 7, thereby separating the tank 19 from the conveyor belt 18. This can provide auxiliary support for the bottom of the tank 19 and improve the accuracy of the plastic composite material cover installation.

[0024] The secondary pressing assembly includes a servo motor fixed to the top of the mounting plate 12. The output shaft of the servo motor passes through the mounting plate 12 and is fixed to a turntable 13 by bolts. The bottom of the turntable 13 is provided with a limiting component for auxiliary positioning of the plastic composite material cover. When the servo motor is started, it drives the turntable 13 to rotate. Under the action of the limiting component, the position of the plastic composite material cover is adjusted so that the top of the plastic composite material cover is in complete contact with the turntable 13, thereby enabling the plastic composite material cover to move vertically downward, further improving the installation accuracy of the plastic composite material cover.

[0025] Furthermore, the limiting component includes a plurality of symmetrically opened positioning holes 16, in which positioning clamping blocks 14 are inserted into two symmetrically distributed positioning holes 16, and one end of the positioning clamping block 14 passes through the positioning hole 16 and is threadedly connected to a nut and fixed on the turntable 13 by the nut. The contact surface between the positioning clamping block 14 and the plastic composite material cover is inclined. At least one keyway 15 is opened on the inner circumference of the plurality of positioning holes 16, and a key block 17 matching the keyway 15 is integrally formed on the outer circumference of the positioning clamping block 14, and the key block 17 can be inserted into the keyway 15. The cooperation between the keyway 15 and the key block 17 can limit the angle of the positioning clamping block 14, so that the two positioning clamping blocks 14 can position and clamp the plastic composite material cover. According to the requirements, the positioning clamping block 14 is inserted into the positioning hole 16, and then the positioning clamping block 14 is fixed with a nut, thereby completing the installation of the positioning clamping block 14. The plurality of positioning holes 16 can be used for plastic composite material covers of different diameters, improving the versatility of the equipment.

[0026] Among them, the electric push rod 3, the cylinder 9, and the conveyor belt 18 are all components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods, and will not be described in detail here.

[0027] The working principle of this utility model is as follows: During use, a can 19 sealed with aluminum foil is conveyed from the outside onto a conveyor belt 18. A plastic composite material cap is placed on the can 19. The conveyor belt 18 is started, moving the can 19 into the mounting frame 2. Simultaneously, two electric push rods 3 are activated, pushing the mounting plate 5 and clamp 7 towards the center, thus clamping the can 19. Further extension of the electric push rods 3 causes the clamp 7 and mounting plate 5 to deform the elastic components, generating elastic force to prevent direct hard contact between the mounting plate 5 and the can 19, thus avoiding deformation. Simultaneously, one inclined surface of the clamp 7 presses against the can 19, moving it onto the clamp 7, thereby separating the can 19 from the conveyor belt 18 and providing auxiliary support to the bottom of the can 19. The cylinder 9 is activated, extending to push the connecting plate 10 and mounting plate 12 downwards. The servo motor is activated, driving the turntable 13 to rotate. Under the action of the limiting components, the plastic composite material... The position of the cover is adjusted so that the top of the plastic composite cover is in full contact with the turntable 13, allowing the plastic composite cover to move vertically downwards, thus ensuring the correct position of the plastic composite cover. Then, the cylinder 9 is activated to compress and deform the spring 11, generating elastic force to slowly apply pressure to the plastic composite cover, avoiding excessive pressure at once that could damage the plastic composite cover. After sealing, the electric push rod 3 is activated to retract, thereby driving the mounting plate 5 and the clamp 7 to reset. Since the tank 19 and the plastic composite cover are limited by the turntable 13, the tank 19 will not be moved by the clamp 7, thus keeping the tank 19 in its original position. After the clamp 7 is completely out of contact with the tank 19, the cylinder 9 is retracted, thereby driving the connecting plate 10, the mounting plate 12, and the turntable 13 to move upwards, thereby disengaging the turntable 13 from the plastic composite cover, allowing the tank 19 to be moved by the conveyor belt 18.
