Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to multi-roll vertical packaging equipment. Background Art

[0002] Packaging equipment is a special equipment that can load and package materials. At present, the packaging machines on the market generally use a lateral conveying method to convey the packaging substrate. For example, a Chinese patent document (publication number: CN218751756U; publication date: March 28, 2023) discloses a packaging device for a stretch film packaging machine, which is characterized in that it is arranged on the frame of the stretch film packaging machine and located at the packaging station of the frame, including: a mounting frame, the mounting frame is arranged at the packaging station; an upper packaging mold, the upper packaging mold is arranged on the mounting frame; a lower packaging mold, the lower packaging mold is arranged on the mounting frame and is located below the upper packaging mold; a first driving cylinder, the first driving cylinder is arranged on the mounting frame, and is connected to the lower packaging mold to drive the lower packaging mold to rise and fall; a second driving cylinder, the second driving cylinder is arranged on the frame, and is connected to the mounting frame to drive the mounting frame to rise and fall.

[0003] The above technical solution is a structure that adopts horizontal conveying of packaging substrates to different stations for packaging processing. The defects of this structure are: the overall length of the equipment is very long, so the space it requires is very large, and it cannot be adapted to be arranged in a smaller workshop. Some vertical packaging equipment on the market, especially when multi-layer substrates need to be pulled and conveyed, the loading and heat sealing stations are usually arranged between the unwinding components, which makes it difficult to observe the internal processing conditions. At the same time, when performing internal maintenance, it is necessary to remove the unwinding component before making room, and the maintenance operation is very inconvenient. In addition, in order to ensure that the packaging substrate can be moved to different stations, it is usually necessary to set up at least one set of traction components to drive the packaging substrate to move, and its overall structure is relatively complex. Utility Model Content

[0004] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a multi-roll vertical packaging device for solving the above-mentioned problems.

On the top of the machine frame, a hopper assembly, a blanking pipe, a vertical sealing assembly, a lifting seat and a cutting assembly are sequentially arranged from top to bottom. A folding plate and a guiding roller group are arranged corresponding to the second base material unwinding rack. The folding plate has a folding groove. After the packaging base material on the second base material unwinding rack passes through the folding plate and the guiding roller group, it is pulled downward in a parallel state with the packaging base material on the first base material unwinding rack to the lifting seat. The lifting seat is connected to a lifting drive assembly, and a transverse sealing assembly is arranged on the lifting seat. When the transverse sealing assembly clamps and transversely seals the packaging base material, the lifting drive assembly drives the lifting seat to descend to realize the traction of the packaging base material.

[0007] The lifting drive assembly includes a first motor, the first motor is in transmission connection with a driving screw, the driving screw is screwed to the lifting seat, a first guide seat is arranged on the lifting seat, and a first guide post passing through the first guide seat is arranged on the machine frame.

[0008] A material patting assembly is arranged between the lifting seat and the cutting assembly. The material patting assembly includes a rear baffle and a material patting pressing plate, and the material patting pressing plate is connected to a first moving drive assembly.

[0009] The vertical sealing assembly includes a fixedly arranged rear vertical sealing plate, and a front vertical sealing plate is arranged corresponding to the rear vertical sealing plate. The front vertical sealing plate is arranged on a moving frame, and the moving frame is connected to a second moving drive assembly.

[0010] The transverse sealing assembly includes a front heat sealing seat and a rear heat sealing seat slidably arranged on the lifting seat. Transverse sealing plates are arranged on both the front and rear heat sealing seats, and the rear heat sealing seat is connected to a third moving drive assembly.

[0017] As shown in the figure, a multi-unwinding vertical packaging device disclosed by the present utility model includes a first base material unwinding rack 1 located on the front side and a second base material unwinding rack 8 located on the left side. On the top of the machine frame, a hopper assembly 3, a blanking pipe 13, a vertical sealing assembly, a lifting seat 20, and a cutting assembly 25 are sequentially arranged from top to bottom. Among them, the cutting assembly 25 is a common cutter structure on the market and belongs to the prior art, so its specific structure will not be described in detail. A folding plate 7 and a guiding roller group 5 are arranged corresponding to the second base material unwinding rack 8. The folding plate 7 has a folding groove 6. After the second packaging base material 9 on the second base material unwinding rack 8 passes through the folding plate 7 and the guiding roller group 5, it is pulled downward in a parallel state with the first packaging base material 2 on the first base material unwinding rack 1 to the lifting seat 20. The lifting seat 20 is connected to a lifting drive assembly. A transverse sealing assembly is arranged on the lifting seat 20. When the transverse sealing assembly clamps and transversely seals the packaging base material, the lifting drive assembly drives the lifting seat 20 to descend to realize the traction of the packaging base material. Specifically, the lifting drive assembly includes a first motor 26. The first motor 26 is in transmission connection with a driving screw 27. The driving screw 27 is screwed to the lifting seat 20. A first guide seat 22 is arranged on the lifting seat 20. A first guide post 23 passing through the first guide seat 22 is arranged on the machine frame. By controlling the first motor 26 to drive the driving screw 27 to rotate, the lifting seat 20 can be driven to lift along the first guide post 23. Further, a material patting assembly is arranged between the lifting seat 20 and the cutting assembly. The material patting assembly includes a rear baffle 12 and a material patting pressing plate 11. The material patting pressing plate 11 is connected to a first moving drive assembly. The first moving drive assembly is a first air cylinder 10. The piston rod of the first air cylinder 10 is connected to the material patting pressing plate 11. By controlling the first air cylinder 10 to drive the material patting pressing plate 11 to act, it can cooperate with the rear baffle 12 to squeeze and flatten the materials added into the packaging base material. The vertical sealing assembly includes a fixedly arranged rear vertical sealing plate 14. A front vertical sealing plate 15 is arranged corresponding to the rear vertical sealing plate 14. The front vertical sealing plate 15 is arranged on a moving frame 16. The moving frame 16 is connected to a second moving drive assembly. The second moving drive assembly is a second air cylinder 28. The piston rod of the second air cylinder 28 is connected to the moving frame 16. By controlling the second air cylinder 28 to drive the moving frame 16 and the front vertical sealing plate 15 to move, the packaging base material is tightly pressed between the front and rear vertical sealing plates to realize vertical heat sealing processing. The transverse sealing assembly includes a front heat sealing seat 17 and a rear heat sealing seat 21 slidably arranged on the lifting seat 20. Transverse sealing plates 18 are arranged on both the front and rear heat sealing seats. The rear heat sealing seat 21 is connected to a third moving drive assembly. The third moving drive assembly is a third air cylinder 24. The third air cylinder 24 is connected to the rear heat sealing seat 21. By controlling the third air cylinder 24 to drive the rear heat sealing seat 21 to act, the packaging base material is clamped between the two transverse sealing plates 18 to perform transverse sealing processing on the base material.

[0018] The working principle of the present utility model is as follows: The first packaging substrate 2 is unwound through the first substrate unwinding rack 1, and the second packaging substrate 9 is unwound through the second substrate unwinding rack 8. After the second packaging substrate 9 is guided by the folding plate 7 and the guide roller group 5, the second substrate 9 can be kept parallel to the first substrate 2 and pulled downward to the lifting seat 20. At this time, the feeding pipe 13 is wrapped between the first and second packaging substrates. Then, by controlling the operation of the vertical sealing assembly, the vertical sealing processing of both sides of the packaging bag substrate is carried out. At this time, the lifting seat 20 is at a high position, and the horizontal sealing assembly on the lifting seat 20 operates to clamp the packaging bag substrate for horizontal heat sealing at the bottom position. At the same time, the lifting seat 20 descends, driving the packaging substrate to be pulled downward. After the heat sealing is completed and it descends to the in-place position, the horizontal sealing assembly releases the packaging substrate, and the lifting seat rises and resets. The hopper assembly 3 opens to send the loaded material into the packaging substrate that has been sealed on three sides through the feeding pipe 13. Then, the horizontal sealing assembly on the lifting seat clamps and heat seals the opening at the top of the package. At the same time, the lifting seat descends again to drive the packaging bag to be pulled downward. In this way, the heat sealing and feeding operations of the packaging bag are realized in a cyclic manner. When the packaging bag that has completed heat sealing and feeding descends to the cutting assembly 25, the cutting assembly operates to cut the packaging bag into single bags or multiple bags and send them downward for delivery.

[0019] With this structure of the present utility model, by providing two substrate unwinding racks, and the unwinding racks are arranged corresponding to the front and rear sides, the front part of the equipment is left vacant, which is convenient for observing the production and processing conditions and also facilitates the adjustment and maintenance operations of the equipment. By arranging the hopper assembly, the feeding pipe, the vertical sealing assembly, the lifting seat, and the cutting assembly in sequence from top to bottom, the packaging substrate can complete the operations of loading, heat sealing, and cutting during the vertical downward movement, which can greatly reduce the occupied area required by the equipment and facilitate its layout in the workshop. In addition, by arranging the horizontal sealing assembly on the lifting seat, the horizontal sealing assembly can pull the packaging substrate downward for traction and conveying when performing horizontal sealing on the packaging substrate. Therefore, the equipment does not need to be additionally equipped with a traction assembly, making its structure simpler.
