Description

Technical Field

[0001] This utility model relates to the field of packaging device technology, specifically to a sealing mechanism for disposable hygiene product packaging devices. Background Technology

[0002] The sealing mechanism of disposable hygiene product packaging devices is a core component that seals the opening of the packaging bag containing hygiene products through heating, pressurization, and other methods, ensuring product hygiene and storage.

[0003] Traditional sealing mechanisms for disposable hygiene product packaging devices often employ a single hydraulic or pneumatic-driven heated pressure plate structure. Sealing is achieved through a single pressure adjustment, lacking a buffer compensation mechanism to accommodate packaging materials of varying thicknesses. When there are slight thickness deviations or shifts in the conveying position, uneven contact pressure between the heated pressure plate and the worktable can occur, leading to problems such as incomplete sealing, missed seals, or damage to the packaging material due to excessive pressure. Furthermore, the heating plate of traditional sealing mechanisms operates at 120-200℃ for extended periods. When heated, packaging materials (such as PE composite film) easily produce adhesive residue that adheres to the heating plate surface. Current cleaning methods rely on periodic manual wiping or simple scraper cleaning. Simple scraper cleaning can easily scratch the anti-stick coating on the heating plate surface, exacerbating subsequent adhesive residue buildup and creating a vicious cycle of "cleaning-damage-more residue." This not only increases equipment maintenance costs but also poses a hygiene and safety hazard due to adhesive detachment contaminating the hygiene products. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a sealing mechanism for a disposable hygiene product packaging device.

[0028] This utility model provides, for example Figure 1-5 The sealing mechanism of the disposable hygiene product packaging device shown includes a base 1, a workbench 2 fixedly connected to one top end of the base 1, an L-shaped support plate 3 fixedly connected to the other top end of the base 1, a protective frame 4 fixedly connected to the bottom of the L-shaped support plate 3, a first hydraulic rod 5 fixedly connected to the top of the L-shaped support plate 3, the bottom of the first hydraulic rod 5 passing through the L-shaped support plate 3 and fixedly connected to an L-shaped connecting plate 6, a second hydraulic rod 7 fixedly connected inside the cavity of the L-shaped connecting plate 6, and a heating sealing pressure plate 8 fixedly connected to the bottom of the second hydraulic rod 7 through a buffer mechanism.

[0029] A first electric push rod 9 is fixedly connected to the outer wall of one end of the L-shaped connecting plate 6. One end of the first electric push rod 9 passes through the inner wall of the L-shaped connecting plate 6 and is fixedly connected to a pressure roller assembly 10. A second electric push rod 11 is fixedly connected to the side wall of the protective frame 4. The other end of the second electric push rod 11 is fixedly connected to a heating plate cleaning assembly 12. An ultrasonic generator 13 and an air compressor 14 are fixedly connected to the top of the L-shaped support plate 3. The air inlet of the air compressor 14 is equipped with a filter mechanism. The output ends of the ultrasonic generator 13 and the air compressor 14 are both fixedly connected to the input end of the heating plate cleaning assembly 12. A display controller 15 is fixedly connected to the side wall of the base 1. The base 1 provides a stable mounting foundation for all components of the mechanism, ensuring overall structural stability during the sealing process and preventing vibration from affecting sealing accuracy. The workbench 2 provides a flat support surface for the packaged goods, ensuring stable packaging position during sealing. The L-shaped support plate 3 provides reliable support for components such as the first hydraulic rod 5 and the protective frame 4, optimizing the layout. The protective frame 4 forms a closed working space to prevent external interference and ensure operational safety. The first hydraulic rod 5 drives the L-shaped connecting plate 6 to rise and fall, enabling vertical switching during sealing operations. The second hydraulic rod 7 provides precise pressure adjustment for the heated sealing plate 8, adapting to packaging materials of different thicknesses. A buffer mechanism compensates for sealing pressure, preventing uneven pressure and ensuring a tight and uniform seal. A heated sealing plate 8 heats the packaging to ensure sealing strength and tightness. A first electric push rod 9 drives the pressure roller assembly 10 to move laterally, performing secondary compaction on the sealing edges to enhance sealing and prevent edge curling. The rolling compaction process of the pressure roller assembly 10 is gentle and does not damage the packaging material. A second electric push rod 11 drives the heating plate cleaning assembly 12 to move precisely to the heated sealing plate 8 for automatic cleaning without manual intervention. An ultrasonic generator 13 provides ultrasonic vibration power to the cleaning assembly. This system efficiently removes adhesive residue. An air compressor 14 provides high-pressure airflow to blow away adhesive debris. A filtration system ensures the high-pressure airflow is clean, preventing impurities from contaminating the heating plate and packaging. A display controller 15 centrally controls the operating parameters of each component, achieving automated coordination of sealing, compaction, and cleaning. This improves operational convenience and sealing quality stability, while avoiding hygiene hazards and coating damage caused by manual cleaning. It solves the problems of uneven sealing pressure due to a lack of buffer compensation in traditional disposable hygiene product packaging sealing mechanisms, which affects sealing quality, and the reliance on manual or scraper cleaning of adhesive residue on the heating plate, which easily damages the coating and affects hygiene and safety.

[0030] To compensate for the sealing pressure and ensure uniform pressure, such as Figure 2-4As shown, the buffer mechanism includes a connecting chamber 16, a guide slide 17, polyurethane friction columns 18, and a hydraulic spring buffer 19. The bottom of the second hydraulic rod 7 is fixedly connected to the connecting chamber 16. The bottom of the connecting chamber 16 has a guide slide 17, and a polyurethane friction column 18 is frictionally connected thereto. The top of the polyurethane friction column 18 passes through the guide slide 17 and is fixedly connected to the top of the heat-sealing plate 8. The bottom of each guide slide 17 is fixedly connected to a hydraulic spring buffer 19, and the top of each hydraulic spring buffer 19 is fixedly connected to the bottom of the corresponding polyurethane friction column 18. The connecting chamber 16 provides installation space for the buffer components, ensuring a compact structure. The hydraulic spring buffer 19 can automatically compensate for pressure according to the thickness of the packaging material, avoiding excessive or insufficient local pressure and ensuring that the pressure of the heat-sealing plate 8 on the packaging is uniform. The polyurethane friction column 18 and the guide slide 17 are in frictional cooperation, which not only assists in buffering but also stabilizes the position of the heat-sealing plate 8 through frictional resistance, preventing displacement.

[0031] In order to purify the intake air and ensure hygiene and safety, such as Figure 3 and 5 As shown, the filtration mechanism includes a connecting ring 20, a filter cover 21, a filter screen 22, and a food-grade antibacterial activated carbon fiber felt 23. The connecting ring 20 is fixedly connected to the air inlet on the side wall of the air compressor 14. The surface of the connecting ring 20 is threaded with the filter cover 21. The surface of the filter cover 21 is fixedly connected with the filter screen 22 through an opening. The food-grade antibacterial activated carbon fiber felt 23 is snapped between the connecting ring 20 and the filter cover 21 at both ends. The filter screen 22 intercepts large particulate impurities in the air to prevent them from entering the air compressor 14 and causing damage. The food-grade antibacterial activated carbon fiber felt 23 adsorbs fine dust and odors and has an antibacterial effect, ensuring that the output airflow meets hygiene standards and avoiding contamination of the heating plate and disposable hygiene products. The connecting ring 20 is threadedly connected to the filter cover 21, which facilitates disassembly, cleaning, or replacement of the filter components, making maintenance convenient.

[0032] To achieve secondary compaction and sealing, and to enhance the airtightness, such as Figure 2-4 As shown, the pressure roller assembly 10 includes a U-shaped bracket 24, and a silicone-coated pressure roller 25 is rotatably connected between the inner walls of the U-shaped bracket 24. The U-shaped bracket 24 provides a stable mounting support for the pressure roller, ensuring smooth rolling. The silicone-coated pressure roller 25 is soft and fits tightly with the packaging material when in contact, avoiding damage to the packaging surface during rolling and compaction. The rolling and compaction of the pressure roller can eliminate air bubbles and gaps at the sealing point, further enhancing the sealing performance, preventing liquid or air leakage, and improving the stability of packaging quality.

[0033] To automatically remove adhesive and protect the heating plate coating, such as Figure 2 and 4As shown, the heating plate cleaning assembly 12 includes a connecting plate 26. An ultrasonic transducer 27 is fixedly connected to the side wall of the connecting plate 26. A high-temperature resistant silicone plate 28 is fixedly connected to the vibration output end of the ultrasonic transducer 27. A perforated spray plate 29 is fixedly connected to the bottom of the connecting plate 26. The ultrasonic transducer 27 and the ultrasonic generator 13 are electrically connected. The air inlet of the perforated spray plate 29 is fixedly connected to the air outlet of the air compressor 14. The connecting plate 26 integrates the transducer and the spray plate, resulting in a compact structure. The ultrasonic transducer 27 converts electrical energy into high-frequency vibration, which is transmitted to the surface of the heating sealing plate 8 through the high-temperature resistant silicone plate 28. This efficiently peels off the adhesive, and the silicone material is soft and does not damage the coating of the heating plate. The perforated spray plate 29 evenly sprays high-pressure airflow to blow away the peeled adhesive debris, achieving thorough cleaning.

[0034] To improve protection and hygiene, such as Figure 1-4 As shown, a high-temperature resistant silicone pad 30 is fixedly connected to the surface of the workbench 2. The bottom surface of the heating sealing pressure plate 8, the air outlet end face of the multi-hole spray plate 29, and the outer surface of the silicone-coated pressure roller 25 are all coated with a Teflon anti-stick coating. The surface of the silicone-coated pressure roller 25 is coated with a food-grade antibacterial coating. The high-temperature resistant silicone pad 30 is used to buffer the sealing pressure, protect the workbench and the packaging, and enhance the positioning stability of the packaging. The Teflon anti-stick coating reduces adhesive adhesion, making it easy to clean and reducing the maintenance frequency. The food-grade antibacterial coating inhibits bacterial growth, meeting the hygiene requirements of disposable hygiene products, avoiding secondary pollution during the packaging process, and ensuring product hygiene and safety.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
