Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and relates to a packaging device for napkins. Background Technology

[0002] A napkin packaging device mainly includes a feeding platform 1, a loading platform 2, a sealing device 3, a discharge conveyor belt 4, a control cabinet 5, and a first support plate 6. The control cabinet 5 is mounted on the first support plate 6, which is equipped with a film feeding device 61. The loading platform 2 is equipped with a paper pushing cylinder 21 and a feeding position 23. The telescopic rod of the paper pushing cylinder 21 has a push plate 22 extending to the feeding position 23. The feeding platform 1, the paper pushing cylinder 21, the sealing device 3, the discharge conveyor belt 4, and the film feeding device 61 are all connected to the control cabinet 5. Cabinet 5 controls the feeding platform 1, the paper-pushing cylinder 2, the sealing device 3, the discharge conveyor belt 4, and the film-feeding device 61. The feeding platform 1 transports the napkins 8. The sealing device 3 is aligned with the inlet position 23. The film conveyed by the film-feeding device 61 passes between the sealing device 3 and the inlet position 23. The paper-pushing cylinder 2 pushes the napkins 8 through the film and into the sealing device 3. The sealing device 3 seals the napkins 8. Subsequent napkins 8 are then pushed out of the sealing device 3 onto the material conveyor belt 4 and sent elsewhere (e.g., ...). Figure 1 (As shown). In use, the paper-pushing cylinder 2 pushes the napkin 7 through the wrapping film and into the sealing device 3. The bottom, front, and top of the napkin 7 are covered with wrapping film. The three sets of folding plates inside the sealing device 3 fold the wrapping film at the rear, left, and right sides of the napkin 7, respectively, before heat sealing. It should be noted that the positions of the three sets of folding plates inside the sealing device 3 are set according to the size of the napkin 7. When sealing napkins of other sizes, the sealing device 3 needs to be disassembled and the positions of the three sets of folding plates inside need to be manually adjusted. Then, the sealing device 3 needs to be reassembled before the napkins of that size can be sealed. If the adjustment is inaccurate, the sealing device 3 needs to be disassembled and readjusted again, which is inconvenient and inefficient. Utility Model Content

[0003] This invention provides a napkin packaging device with a switchable sealing device to solve the problem that existing napkin packaging devices require disassembling the sealing device for adjustment when packaging napkins of different sizes, resulting in cumbersome operation and low work efficiency.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes a feeding platform, a loading platform, a discharge conveyor belt, a control cabinet, and a first support plate.

Then, the second packaging device 753 slides close to the feeding position 23 and places the medium-sized napkins 8 on the feeding table 1. The push rod 11 pushes the medium-sized napkins 8 to the feeding position 23. The paper pushing cylinder 21 drives the push plate 22 to push the napkins 8 through the film and into the second packaging device 753. After the second packaging device 753 packages the medium-sized napkins 8, it is sent to the conveyor belt for delivery elsewhere. When it is necessary to package large-sized napkins 8, the control cabinet 5 sets the current packaging mode to large-sized napkins 8. The second packaging device 753 returns to its original position, and the stepper motor 72 drives the rotating frame to rotate so that the third packaging device 763 is positioned at the lower end and aligned with the feeding position 23. Then, the third packaging device 763 slides close to the feeding position 23 and places the large-sized napkins 8 on the feeding table 1. The push rod 11 pushes the large-sized napkins 8 to the feeding position 23. The paper pushing cylinder 21 drives the push plate 22 to push the napkins 8 through the film and into the third packaging device 763. After the third packaging device 763 packages the large-sized napkins 8, it is sent to the conveyor belt for delivery elsewhere. When it is necessary to package extra-large napkins 8, the control cabinet 5 sets the current packaging mode to extra-large napkin 8. The third packaging device 763 returns to its original position, and the stepper motor 72 drives the rotating frame to rotate so that the fourth packaging device 773 is positioned at the lower end and aligned with the feeding position 23. Then, the fourth packaging device 773 slides close to the feeding position 23 and places the extra-large napkin 8 on the feeding table 1. The push rod 11 pushes the extra-large napkin 8 to the feeding position 23. The paper pushing cylinder 21 drives the push plate 22 to push the napkin 8 through the film and into the fourth packaging device 773. After the fourth packaging device 773 packages the extra-large napkin 8, it is sent to the conveyor belt for delivery elsewhere.
