[0001] This utility model relates to the field of constant temperature sealing technology for packaging, and in particular to a cold cutting knife structure for constant temperature sealing of packaging. Background Technology

[0002] The packaging constant temperature sealing and cold cutting knife structure is a composite mechanism integrating constant temperature sealing and cold cutting functions. It is mainly used in automated packaging equipment (such as sealing and cutting machines, bagging machines, bowl sealing machines, etc.) to achieve efficient sealing and precise cutting in continuous production processes. However, existing packaging constant temperature sealing and cold cutting knife structures cannot perform sealing and cold cutting simultaneously, resulting in separate sealing and cold cutting operations, which reduces their operational and work efficiency. Furthermore, they cannot synchronously drive the conveyor belt, sealing components, and cold cutting knife to come together or move apart, thus hindering their effective use and reducing their efficiency. Therefore, we propose a packaging constant temperature sealing and cold cutting knife structure. Utility Model Content

[0016] Reference Figures 1 to 4 This utility model provides a packaging constant temperature sealing cold cutting knife structure, which includes two U-shaped brackets 1. The two U-shaped brackets 1 are connected to side plates 2 by bolts on the opposite sides. The top of the two side plates 2 is connected to the same U-shaped plate 16 by bolts. A bidirectional lead screw 3 is movably connected between the two side plates 2 near the bottom by a bearing. Nuts 5 are respectively fitted on the two bidirectional lead screws 3 near the front and rear sides. A servo motor 27 is bolted to the rear wall of the right side plate 2 near the bottom. The front end and rear end of the bidirectional lead screw 3 extend through the inner ring of the bearing to the outside of the U-shaped bracket 1 and are connected to a rotating plate 4. The rear end of the bidirectional lead screw 3 passes through the rear rotating plate 4 and is connected to the output shaft of the servo motor 27.

[0017] The left sides of the two side plates 2 are bolted to guide rails 10, and the left sides of the two guide rails 10 are slidably connected to a first movable plate 8. The right side of the first movable plate 8 is bolted to a conveyor housing 17. Inside the conveyor housing 17, near the left and right sides, conveyor rollers 19 are movably connected via shafts and bearings, respectively. A conveyor belt 21 connects the two conveyor rollers 19. The front side of the conveyor housing 17, near the right side, is bolted to a drive motor 22, and the front end of the shaft on the front wall of the right conveyor roller 19 passes through the inner ring of the bearing and connects to the output shaft of the drive motor 22. The bottom of the conveyor housing 17 is bolted to a bonding plate 7, and the bottom of the bonding plate 7, near the four corners, is bolted to limit rods 23. The top of the U-shaped bracket 1 has limit holes that match the limit rods 23. This structure enables simultaneous sealing and cold cutting, effectively avoiding the separation of sealing and cold cutting, thus improving operational and work efficiency.

[0018] The bottom of the U-shaped plate 16 is connected to several evenly distributed insert rods 18, and the top of the conveyor belt 21 is provided with insertion holes 20 that match the insert rods 18. A second movable plate 11 is slidably connected to the left side of the two guide rails 10. A docking plate 13 is bolted to the top of the second movable plate 11, and a sealing piece 12 is bolted to the bottom of the docking plate 13. A first connecting rod 6 is movably connected to the right side of the two rotating plates 4 on opposite sides via a shaft and bearing. The top sides of the two first connecting rods 6 are movably connected to the front and rear walls of the first movable plate 8 via shafts and bearings, respectively. The left sides of the two rotating plates 4 on opposite sides are movably connected via shafts and bearings, respectively. The system includes two second connecting rods 9. Near the top of the two connecting rods 9, their opposite sides are movably connected to the front and rear walls of the second movable plate 11 via shafts and bearings. A mounting plate 25 is bolted to the bottom right side of the U-shaped plate 16. A pipe body 24 is threaded through the top of the mounting plate 25 near both the front and rear sides, and vertical rods 15 pass through the pipe bodies 24. The bottom ends of the two vertical rods 15 extend to the bottom of the pipe bodies 24 and are bolted to the same cold-cutting blade 26. An electric cylinder 14 is bolted to the top center of the mounting plate 25, and a through hole is provided at the top of the mounting plate 25. The bottom end of the push rod on the electric cylinder 14 passes through the through hole and is bolted to the top of the cold-cutting blade 26. This structure allows the conveyor belt 20, the sealing component, and the cold-cutting blade to move together or apart synchronously, thus enabling effective use and improving efficiency.

[0019] Working principle: In operation, this technical solution first drives the drive motor 22 to rotate the conveyor roller 19 and the conveyor belt 20 to achieve conveying. The servo motor 27 drives the bidirectional lead screw 3 to rotate forward or reverse, causing the two nuts 5 to move away from each other or close together. The bidirectional lead screw 3 drives the rotating plate 4 to swing up and down. The rotating plate 4 drives the first movable plate 8 and the second movable plate 11 to move away from each other or close together on the guide rail 10 through the first connecting rod 6 and the second connecting rod 9 respectively. The first movable plate 8 and the second movable plate 11 drive the conveyor belt 20 and the sealing part 12 to move away from each other through the conveyor housing 17. The sealing is achieved by the closing motion of the two parts, while the push rod on the electric cylinder 4 extends and retracts, driving the vertical rod 15 to slide downward and then upward inside the pipe body 24 via the mounting plate 25. At the same time, the mounting plate 25 drives the cold cutting blade 26 to move downward or upward to achieve cold cutting. This allows the conveyor belt 20, the sealing part, and the cold cutting blade to move together or away synchronously, thus enabling effective use and improving its efficiency. It also allows for synchronous sealing and cold cutting, effectively avoiding the separation of sealing and cold cutting, thereby improving its operational and work efficiency.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
