Description

Technical Field

[0001] This utility model relates to the field of bottled water production technology, specifically to a bottled water sealing device. Background Technology

[0002] In the bottled water production process, the sealing device is the core equipment to ensure the product's airtightness and improve production efficiency, and it is directly related to the product's shelf life and market reputation.

[0003] Most bottled water sealing devices currently on the market suffer from insufficient sealing stability, failing to effectively secure the bottle during the sealing process, leading to bottle movement and inaccurate film adhesion. Furthermore, their film conveying and stamping structures are poorly designed, resulting in poor film formation regularity and limited flexibility in adapting to different bottle sizes, making it impossible to quickly adjust limit and clamping parameters. In addition, some devices lack a buffer structure in their stamping unit, making them prone to film breakage or bottle damage. Overall structural coordination is poor, affecting production continuity and failing to meet the needs of large-scale, refined bottled water production, thus limiting their applicability and practicality. Therefore, those skilled in the art provide a bottled water sealing device to solve the problems mentioned in the background art. Utility Model Content

The stamping column 761 passes through the stamping hole 78 of buffer plate 77 and bottom plate 72, stamping the sealing film 9 into a circle and attaching it to the bottle mouth. The first telescopic spring 762 and the second telescopic spring 771 play a buffering role to prevent excessive stamping pressure from damaging the bottle or sealing film. The diameter of the stamping column 761 must match the bottle mouth specification to ensure accurate sealing film application.

[0029] As one implementation method in this embodiment, please refer to the appendix. Figure 6 Appendix Figure 7 As shown, the film feeding unit 8 includes two pairs of mounting ear plates 81 disposed on the left and right sides of the top surface of the fixed top plate 21. A roll shaft 82 is rotatably disposed between the mounting ear plates 81 on the same side. A sealing film roll is sleeved on one side of the roll shaft 82, and the end of the roll shaft 82 on the other side passes through the mounting ear plate 81 and is connected to the roll conveyor motor 83 for transmission. The roll conveyor motor 83 is fixed on a bracket that is fixed to the fixed top plate 21. The sealing film 9 is conveyed on the roll shafts 82 on the left and right sides by the transmission units disposed at the left and right ends of the bottom plate 72. The transmission unit includes two pairs of rotating ear plates 721 fixed to the left and right ends of the bottom plate 72. The outer ends of the rotating ear plates 721 on the same side extend upward and are inclined, and a roller shaft 722 is rotatably disposed between them. The bottom side of the roller shaft 722 and the top surface of the bottom plate 72 form a feeding slit for conveying the sealing film 9.

[0030] The roll conveyor motor 83 drives the right roll shaft 82 to rotate, pulling the sealing film 9 out from the left roll shaft 82. The film is laid flat on the top surface of the base plate 72 through the feed seam between the roller shaft 722 and the base plate 72, realizing the automatic conveying of the sealing film 9. After each stamping is completed, the roll conveyor motor 83 rotates at a certain angle to convey a new sealing film 9 to the stamping position. The roller shaft 722 can reduce the friction of the sealing film 9 during conveying and ensure smooth conveying.

[0031] In practical implementation of this utility model: During use, first adjust the limiting side rail assembly 4 according to the water bottle specifications, loosen the fixing bolt 45, move the connecting rod 42 to drive the railing 44 to adjust to a suitable distance, ensuring that the water bottle can be transported smoothly and without deviation, and tighten the fixing bolt 45 to fix it; place the sealing film roll on the left winding shaft 82, pull out the end of the sealing film 9, pass it under the roller shafts 722 at both ends of the base plate 72, lay it flat on the top surface of the base plate 72 and fix it on the right winding shaft 82; start the conveyor motor 33, the conveyor belt 32 drives the water bottle to be transported downwards to the stamping unit 7, and when the water bottle reaches the designated sealing position, the conveyor motor 33 stops; start the telescopic cylinder 62, the telescopic cylinder 62 drives the clamping plates 63 to move towards each other, and the toothed groove 64 fits against the outer wall of the water bottle to clamp and fix it; start Cylinder 5, the telescopic shaft of cylinder 5 pushes the connecting plate 73 to move downward along the fixed column 71, causing the pressure plate 76 to move downward. The stamping column 761 passes through the stamping holes 78 of the buffer plate 77, the sealing film 9 and the bottom plate 72 in sequence, stamping the sealing film 9 into a circular seal and tightly fixing it to the mouth of the water bottle. After stamping, the telescopic shaft of cylinder 5 retracts and resets, causing the pressure plate 76 to return to its original position. The first telescopic spring 762 and the second telescopic spring 771 assist in the buffer reset. The telescopic cylinder 62 is started, the clamping plate 63 moves in the opposite direction to release the water bottle, and the roll material conveying motor 83 rotates at a preset angle to convey a new sealing film 9 to the top surface of the bottom plate 72. Finally, the conveying motor 33 is started to send the sealed water bottle away, and the next water bottle to be sealed enters the designated position. The above steps are repeated to achieve continuous sealing operation.
