Description

Technical Field

[0001] The invention relates to the technical field of mini sanitary napkin cutting, in particular to a mini sanitary napkin cutting device capable of positioning a film envelope. Background Art

[0002] In the field of modern sanitary products, mini sanitary napkins are innovative products that can meet the diverse needs of consumers. In the processing of mini sanitary napkins, the cutting link is particularly critical, that is, the continuous sanitary napkin material is divided into individual finished products through precise cutting, and then wrapped and packaged to ensure the sterility of the product and the safety of transportation and storage.

[0003] During the production of mini sanitary napkins, after the raw materials undergo multi-layer lamination and embossing, they are cut into standard-sized individual units using high-speed cutting equipment. The cut mini sanitary napkins then enter the film wrapping process, where each mini sanitary napkin is sterilely wrapped individually or in batches. However, most current film wrapping systems use large-diameter film rolls for unwinding. While this design significantly extends the working time of a single unwinding cycle and reduces the frequency of roll changes, the film rolls are bulky and heavy (often weighing tens of kilograms). When the film roll is exhausted, manual intervention is required. Workers remove the exhausted film roll, a laborious and time-consuming process requiring the use of tools. A new film roll is then installed and adjusted to ensure the packaging film is flat and wrinkle-free. Only after confirming that the film roll is correctly installed can the production line be restarted. This roll-changing process is cumbersome, and frequent manual intervention increases operational risks. This is especially true during long, high-intensity work environments, where worker fatigue increases, potentially compromising roll-changing efficiency and safety. Summary of the Invention

[0035] The staff puts multiple rolls of packaging film into the storage box 1020, and the packaging film rolls along the storage box 1020 into the feeding box 1022, controls the movable end of the multi-stage electric push rod 1021 to extend, drives the feeding box 1022 to move upward, and the feeding box 1022 pushes the packaging film upward so that the packaging film is close to the spline shaft 1012. At this time, the baffle 1025 can block the packaging film in the storage box 1020, so that the packaging film cannot roll into the feeding box 1022. The upward movement of the feeding box 1022 can also drive the connecting block 1023 to move upward, and the connecting block 1023 drives the sliding frame 1014 to move backward through the connecting rod 1024. The spring 1015 is stretched, and the sliding frame 1014 drives the spline shaft 1012 to move backward, moving the spline shaft 1012 The packaging film is opened to avoid collision between the packaging film and the spline shaft 1012. The feeding box 1022 continuously pushes the packaging film upwards, and the packaging film contacts the supporting roller 1029 and pushes the supporting roller 1029 to move the two supporting rollers 1029 away from each other. The spring 2 1028 is compressed, and then the packaging film and the supporting roller 1029 are disengaged. Under the action of the spring 2 1028, the two supporting rollers 1029 move towards each other. At this time, the packaging film has moved to the front of the spline shaft 1012, and the spline shaft 1012 is just aligned with the sleeve of the packaging film. The movable end of the multi-stage electric push rod 1021 is controlled to shorten, driving the feeding box 1022 to move downward. The supporting roller 1029 can support the packaging film to prevent the packaging film from falling. The feeding box 1 022 moves downward, driving the connecting block 1023 to move downward, and the connecting block 1023 drives the sliding frame 1014 to move forward through the connecting rod 1024, and the spring 1015 returns to its original state. The spring 1015 can assist the sliding frame 1014 to move forward, making the sliding frame 1014 move forward more smoothly, and the sliding frame 1014 drives the spline shaft 1012 to move forward, and the spline shaft 1012 is inserted into the sleeve of the packaging film. Then the spline shaft 1012 will be inserted into the circular hole on the front side of the limiting frame 1030, and the limiting frame 1030 can limit the packaging film to prevent the position of the packaging film from shifting. At this time, the baffle 1025 no longer blocks the packaging film in the storage box 1020, and the packaging film in the storage box 1020 will roll to the feeding box 1022. , then the staff will pass the upper packaging film around the guide roller 1016 and the guide roller 2 1017, and pass it around the mounting wheel 103, and then pass the lower packaging film around the guide roller 3 1018 and pass it between the conveyor 1 7 and the conveyor 2 8, and finally put the lower packaging film on the conveyor 2 8. Then the staff will pass the sanitary napkin material around the right guide roller 6, the rotating wheel 4 and the left guide roller 6 in turn. At this time, the cutter 5 contacts the sanitary napkin material, and then the sanitary napkin material is reeled through the external reeling device. At the same time, the output shaft of the motor 1 3 drives the rotating wheel 4 to rotate, and the rotating wheel 4 drives the cutter 5 to rotate. The cutter 5 and the sanitary napkin material run synchronously. The conveyor 1 7 supports the sanitary napkin material, and the cutter 5 cuts the sanitary napkin material.The sanitary napkin material is divided into individual mini sanitary napkins, and the conveyor 1 7 conveys the cut mini sanitary napkins to the left. The cut mini sanitary napkins move along the guide plate 9 to the conveyor 2 8, and the cut mini sanitary napkins will fall onto the packaging film. The conveyor 2 8 conveys the cut mini sanitary napkins to the left, so that the cut mini sanitary napkins are close to the mounting wheel 103. At the same time, the packaging film is reeled in by an external reeling device, so that the packaging film and the conveyor 2 8 run synchronously. The cut mini sanitary napkins will enter between the two packaging films, and the cut mini sanitary napkins are wrapped. Then the output shaft of the motor 2 102 drives the mounting wheel 103 to rotate, and the mounting wheel 103 drives the arc-shaped hot melt block 104, the blade 1 105 and the blade 2 106 to rotate, and the support plate 10 1 supports the packaging film, the arc-shaped hot melt block 104 performs heat-melt sealing on the packaging film, and the blade 105 and blade 2 106 cut the packaging film to complete the packaging of the mini sanitary napkin. Blade 105 will enter the knife groove at the top of the support plate 101, ensuring that blade 105 can cut the packaging film. At the same time, the output shaft of motor 3 1011 drives the rotating sleeve 1010 to rotate through the gear. The rotating sleeve 1010 drives the spline shaft 1012 to rotate, and the spline shaft 1012 drives the packaging film to rotate and release the packaging film, preventing the external winding device from pulling the packaging film. When the packaging film on the spline shaft 1012 is exhausted, the above operation is repeated to automatically replace the packaging film, reducing manual operation, alleviating staff fatigue, and improving roll changing efficiency and safety.

Three air ducts 14 are evenly spaced and connected to the connecting plate 13.

[0037] When the packaging film on the spline shaft 1012 is exhausted, the sleeve of the packaging film will remain on the spline shaft 1012. When the spline shaft 1012 moves backward, the sleeve of the packaging film will fall off the spline shaft 1012. At this time, the feeding box 1022 is pushing the packaging film upward, so the sleeve will fall onto the packaging film. The air duct 14 is connected to the air source, and the air is ejected through the air duct 14 and sprayed toward the spline shaft 1012. The air will blow the sleeve, and the sleeve will fall onto the inclined plate 12. Then the sleeve will roll along the inclined plate 12 into the material guide box 11. There is a notch at the bottom of the material guide box 11, and the sleeve can be taken out for recycling.
