Description

Technical Field

[0001] This application relates to the field of health tea processing equipment, and in particular to a packaging device for health tea bags. Background Technology

[0002] With increasing health awareness, health-promoting teas are gaining popularity among consumers, leading to a continuous rise in market demand. As a convenient form of health beverage packaging, health-promoting tea bags require efficient and precise packaging equipment to meet the demands of large-scale production. These tea bags contain various raw materials, all dried tea leaves. During the feeding process, these leaves may break or not fully enter the filling mechanism, resulting in tea bags containing ingredients that do not meet the specified weight requirements. Traditional packaging equipment uses dynamic weighing devices and electric pushers to remove tea bags that do not meet the weight requirements. However, if an empty bag or a tea bag with very little material is present, the electric pusher, combined with the speed of the conveyor belt, can cause the tea bag to drift, preventing it from being conveyed to the waste bin according to the original route.

[0003] Chinese patent application number 2023216014494 proposes a tea bag processing system. The system involves folding a tea bag paper in half and placing it in the side-sealing station of a side-sealing mechanism. Under the action of the side-sealing component, the side of the folded tea bag paper with an opening is sealed. The tea bag paper is then conveyed downwards to the heat-sealing component. When the heat-sealing rollers of the two heat-sealing components rotate synchronously until the heat-sealing edges contact each other, the tea bag paper is heat-sealed. As the heat-sealing rollers continue to rotate, the tea bag paper is heat-sealed into several tea bags of the same size. Combined with the feeding of a quantitative feeding mechanism, after the inner tea bag is fully packaged, the tea bags are then orderly conveyed one by one to the separation component station of the outer packaging mechanism. They enter between two sets of packaging paper and are heat-sealed and cut by the heat-sealing and cutting components to produce complete tea bags.

[0004] Regarding the aforementioned technologies, the inventors discovered the following deficiency: the aforementioned patent does not include a tea bag quality inspection process. Utility Model Content

The conveyor belt includes a drive roller 3 and a driven roller 4. A chain belt 5 is rotatably connected to the drive roller 3 and the driven roller 4 for conveying tea bags. The chain belt 5 is prior art. There are two chain belts 5, which are symmetrically arranged about the center line of the drive roller 3. The two chain belts 5 are arranged side by side along the drive roller 3 and the driven roller 4. Partitions 6 are provided on the two chain belts 5. There are multiple partitions 6, which are evenly spaced along the length of the chain belts 5. Two adjacent partitions 6 cooperate with a portion of the two chain belts 5 to form a receiving area for placing tea bags. The receiving area has a rectangular structure. The tea bags are transferred to the receiving area by the dynamic weighing device 2, and one tea bag is placed in each receiving area. The chain belt 5 includes chain plates 7 arranged sequentially at both ends and hinged together. The chain plates 7 have a rectangular strip structure. Folding plates 8 are rotatably connected to the ends of the chain plates 7 on both chains 5 that are close to each other. The folding plates 8 have the same width and thickness as the chain plates 7. The chain plates 7 are connected to the folding plates 8 via a rotating shaft. Torsion springs are provided at both ends of the rotating shaft. Placement slots for the torsion springs are provided inside the chain plates 7 and folding plates 8. The torsion springs are existing technology. Under normal conditions, the folding plates 8 are parallel to the chain plates 7 by relying on the torsion springs. Baffles 14 are provided at the ends of the two chains 5 that are far apart from each other. Each chain plate 7 is screwed with a baffle 14. The width of the baffle 14 is equal to the width of the chain plate 7. There are multiple baffles 14, each corresponding to one of the chain plates 7. A push mechanism for removing waste material and electrically connected to the control center is provided on the frame 1. The push mechanism includes a push rod motor 9. When the output shaft of the push rod motor 9 moves downward, the folding plates 8 located in the receiving area will rotate, and the waste material will fall from the conveyor belt. A waste bin for receiving waste materials is detachably connected to the frame 1. The waste bin is located in the middle of the conveyor belt, and the opening of the waste bin is set close to the chain plate 7 to prevent the falling material bags from floating out of the waste bin.

[0021] In one embodiment, according to the appendix Figure 2 As shown, each chain plate 7 of the same chain belt 5 within the bearing area is provided with a retainer 10, and adjacent retainers 10 are detachably connected by ropes 11 to ensure that the folding plates 8 located in the same bearing area rotate under the action of the push rod motor 9. A spring-loaded rope mechanism 12 is screwed to one end of the partition plate 6 away from the folding plate 8. There are four spring-loaded rope mechanisms 12, arranged symmetrically in pairs about the center line of the folding plate 8. The ropes 13 of the spring-loaded rope mechanism 12 are connected to the folding plate 8, assisting the folding plate 8 in resetting after rotation. A fixing groove for fixing the partition plate 6 is provided in the middle of the baffle 14. The two ends of the partition plate 6 are detachably connected to the baffles 14 on the two chain belts 5, and the baffles 14 can be set to fix the partition plate 6 according to the size of the tea bag. A recessed groove is provided at the position where the folding plate 8 and the partition plate 6 are close to each other, and a magnet 15 for positioning is glued into the recessed groove.

[0022] In one embodiment, according to the appendix Figure 3 As shown, an upper frame 16 is bolted to the frame 1. The upper frame 16 has a "U"-shaped structure, and a guide rod 17 is bolted to the upper frame 16. The guide rod 17 has a hollow structure. A movable rod 18 is slidably connected inside the guide rod 17. The movable rod 18 is connected to the end of the guide rod 17 by a spring 19. A push rod motor 9 is fixed to the end of the movable rod 18 away from the guide rod 17. A flat plate 20 is keyed to the output shaft of the push rod motor 9. A push ring 21 for covering the tea bag is provided on the side of the flat plate 20 away from the push rod motor 9.

[0023] The implementation principle of the packaging equipment for health tea bags in this application embodiment is as follows: When the packaged tea bags pass above the dynamic weighing equipment, the dynamic weighing equipment quickly senses the weight of the tea bags and transmits the data to the control center in real time. The control center compares and judges the weight according to the preset standard weight parameters and selects whether to start the push rod motor when the tea bags pass below the push rod motor. After the tea bags are transferred to the receiving area on the conveyor belt by the dynamic weighing equipment, if the weight of the tea bags does not meet the standard, the push rod motor pushes the plate and push ring to move down. The folding plate connected by the two chains in the receiving area rotates, and the tea bags fall into the waste bin. The conveyor belt continues to work. During the downward movement of the push ring, it is pushed by the conveyor belt a set distance. After the push ring moves out of the receiving area, the push rod motor resets under the action of the spring. The folding plate resets under the action of the torsion spring and the spring-loaded rope mechanism, and the magnet assists in the positioning of the folding plate.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
