[0002] Toilet paper, as a daily necessity, is widely used in homes, offices, and public places. To prevent the paper from getting damp, contaminated, or scattered during transportation or storage, it is usually packaged in bags to ensure cleanliness, hygiene, and ease of handling. During the production process, a sealing mechanism heat-seals and cuts the open end of the packaging bag, ensuring a firm seal and a smooth appearance, thereby guaranteeing the overall airtightness and aesthetics of the packaging.

[0003] However, existing sealing mechanisms use bolts to directly fix the cutting blade to the connecting frame. This requires disassembling each bolt individually with tools when replacing or maintaining the cutting blade, which is cumbersome and time-consuming, affecting production efficiency and hindering rapid inspection and maintenance. Furthermore, repeated disassembly can cause bolts to strip or break, reducing connection reliability and consequently affecting the overall operational stability of the equipment. This impacts the long-term safety and sealing accuracy of the equipment, and increases maintenance costs.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In this embodiment, refer to Figure 1 - Figure 6 The present invention relates to a toilet paper packaging sealing mechanism, comprising a support 1, two sliding plates 2 symmetrically arranged on the support 1, and a driving component 3. A heat-sealing blade 4 is symmetrically arranged at one adjacent end of each of the two sliding plates 2. A connecting frame 5, which cooperates with the driving component 3, is provided at the other end of each sliding plate 2. One of the connecting frames 5 has a cutting blade 6 that cooperates with the heat-sealing blade 4. The cutting blade 6 is installed at one end of the connecting frame 5 via a quick-release assembly 7. The connecting frame 5 is slidably mounted to one end of the sliding plate 2 via a support spring 51. The sliding plate 2 has a limiting rod 22 that cooperates with the support spring 51. The support spring 51 is sleeved on the outside of the limiting rod 22 and abuts against the connecting frame 5 and the sliding plate 2.

[0019] The heat-sealing knife 4 is equipped with a heating element. When the heating element is energized, it heats the heat-sealing knife 4 to reach the preset sealing temperature, thereby completing the heat-sealing process of the packaging material. Each of the two adjacent ends of the heat-sealing knives 4 has a clearance groove that cooperates with the cutting knife 6. This allows the cutting knife 6 to smoothly cut into the sealed area of ​​the packaging material after heat sealing, achieving a seamless connection between heat sealing and cutting actions while avoiding interference between the cutting knife and the heat-sealing knife, ensuring cutting accuracy and the integrity of the heat-sealed surface.

[0020] When the packaging material enters the sealing area, the two driving components 3 push the sliding plates 2 and connecting frame 5 at both ends closer together, causing the two heat sealing blades 4 to come closer together and press the packaging material, completing the heat sealing. Through the continuous pushing of the driving components 3, the connecting frame 5 compresses the support spring 51, while simultaneously pushing the cutting blade 6 to the heat sealing position. The cutting blade 6 then cuts the packaging material at the sealing point, completing a single sealing and cutting operation.

[0021] After cutting is completed, the drive unit 3 resets, causing the sliding plate 2 and the connecting frame 5 to retract together. At this time, the support spring 51 loses its pressure and begins to recover its deformation, causing the connecting frame 5 to spring back, so that the cutting blade 6 disengages from the heat-sealing position, preparing for the next sealing and cutting action. Subsequently, by repeatedly performing the above actions, continuous automatic sealing and cutting operations on packaging materials can be achieved.

[0022] Two quick-release components 7 are provided, and the two quick-release components 7 are respectively located on both sides of the connecting frame 5.

[0023] The quick-release assembly 7 includes a fixed base 71 and a connecting block 72 slidably mounted on one end of the fixed base 71. One end of the connecting block 72 is provided with an elastic fixing pin 721 that cooperates with the cutting blade 6. A locking block 74 for fixing the connecting block 72 is slidably mounted in the fixed base 71 via a return spring 73. One end of the locking block 74 is provided with a latching block 741. The connecting block 72 and the fixed base 71 are respectively provided with a latching groove 722 and a sliding groove 711 that cooperate with the latching block 741.

[0024] The cutting blade 6 has mounting holes at both ends that mate with the elastic fixing pin 721. The elastic fixing pin 721 has a through groove, which allows the elastic fixing pin 721 to contract radially when subjected to external force, making it easy to quickly remove or install it from the mounting hole.

[0025] The end of the elastic retaining pin 721 is chamfered. When the chamfer contacts the mounting hole, it guides the elastic retaining pin 721 to elastically contract and smoothly insert into the mounting hole for quick positioning and connection. When it is necessary to remove the elastic retaining pin 721 from the mounting hole, simply apply external force to squeeze both sides of the through groove to make the elastic retaining pin 721 radially contract, and apply axial tension to complete the quick separation of the elastic retaining pin 721 from the mounting hole, thus enabling the quick disassembly of the cutting blade 6.

[0026] The locking block 741 can slide back and forth in the sliding groove 711 by the elastic force of the return spring 73, thereby entering or disengaging from the locking groove 722, realizing the quick locking and releasing of the connecting block 72. In this embodiment, the locking block 741 automatically embeds into the locking groove 722 under the action of the return spring 73, realizing the stable fixation of the connecting block 72; when it is necessary to replace the cutting blade 6, simply press the locking block 74 to disengage the locking block 741 from the locking groove 722, and the connecting block 72 and the cutting blade 6 can be pulled out for replacement or maintenance.

[0027] One end of the fixed base 71 is provided with a limiting groove 712 that mates with the connecting block 72, and one end of the connecting block 72 is provided with a limiting block 723 that mates with the limiting groove 712. The cooperation between the limiting block 723 and the limiting groove 712 makes the sliding of the connecting block 72 within the fixed base 71 more stable, preventing it from shifting during locking or releasing, which would prevent the locking block 741 from accurately engaging or disengaging from the locking groove 722, thus ensuring a smooth and reliable quick-release process.

[0028] In this embodiment, the width of the limiting groove 712 gradually decreases from top to bottom, forming a V-shaped structure. The limiting block 723 has a corresponding V-shaped matching design. The two work together to form a guiding and positioning mechanism. When the connecting block 72 slides along the fixed base 71, the V-shaped structure can automatically correct itself, ensuring that the locking block 741 is accurately aligned with the sliding groove 711 and the locking groove 722, thereby improving the reliability and assembly efficiency of the quick-release component 7.

[0029] Cutting blade 6 is a serrated blade. The serrated blade has a serrated edge, which can cut the packaging material while creating uniform serrated cuts at the sealing edge. This not only improves the packaging's aesthetics but also enhances the controllability of the tear initiation point, making it easier for users to open. This improves the practicality of the packaging and the user experience.

[0030] Guide sleeves 21 are provided on both sides of the sliding plate 2, and guide rods 11 that cooperate with the guide sleeves 21 are provided on both sides of the bracket 1. Through the cooperation of the guide sleeves 21 and the guide rods 11, it is ensured that the sliding plate 2 can slide smoothly on the bracket 1 along the guide rods 11, avoiding deflection or jamming during the movement, which would cause the heat sealing knife 4 to deviate and affect the sealing effect of the packaging material.

[0031] One end of one of the sliding plates 2 is equipped with a suction head 8 that is connected to the outside. The suction head 8 is connected to an external negative pressure waste collection device through a pipe. Under the action of negative pressure, the suction head 8 can adsorb the packaging waste and debris generated during the cutting process and transport them to the external negative pressure waste collection device to achieve timely cleaning of waste, prevent it from scattering in the work area or adhering to the surface of the packaging material, keep the working environment clean, and at the same time avoid the waste from interfering with the heat sealing process.

[0032] The beneficial effects of this utility model are as follows: The quick-release component 7 allows for the rapid replacement of the cutting blade 6 without the need for tools, reducing maintenance difficulty and improving maintenance efficiency. Simultaneously, it makes the connection between the cutting blade 6 and the connecting frame 5 more stable and reliable, thereby effectively improving the operational stability and safety of the sealing mechanism. This avoids problems such as stripping and breakage caused by repeated bolt disassembly and reassembly, ensuring sealing accuracy and long-term operational reliability of the equipment. The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Although this utility model is disclosed above with reference to a preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the utility model's technical solution.
