[0002] In the modern packaging industry, a sealing and cutting machine is a widely used automated device for plastic-sealing products to protect them from external contamination and damage, and at the same time provide an aesthetic packaging appearance.

[0003] However, after the existing sealing and cutting machines plastic-seal the packages, there is often a significant problem. As Figure 1 shown in the structural diagram of the plastic-sealing film covering a rectangular box, if the sealing and cutting device does not form a tear notch 20 on the plastic-sealing film 10, since the plastic-sealing film 10 is completely closed, this makes it difficult for users to find a suitable opening when trying to open the package, increasing the difficulty of opening the package. Sometimes, tools such as scissors or blades even need to be used to assist in opening, which not only reduces the user experience but also increases the risk of opening the package. Summary of the Utility Model

[0004] To solve the problem that there is no tear notch on the plastic-sealing film after the sealing and cutting machine plastic-seals the products, the utility model provides a sealing and cutting device for a sealing and cutting packaging machine.

[0030] The present utility model provides the following description with reference to the drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0031] In the description of the present utility model, orientation descriptions are involved. For example, the orientations or positional relationships indicated by up, down, front, back, left, right, etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0032] It should be understood that when an element (e.g., the first element) is "connected" to another element (e.g., the second element), the element can be directly connected to the other element, or there can be an intermediate element (e.g., the third element) between the element and the other element.

[0033] Embodiments of the present utility model provide a sealing and cutting device for a sealing and cutting packaging machine, as Figure 2-10 shown and including:

[0034] A main sealing and cutting assembly 100, for sealing and forming;

[0035] An auxiliary sealing and cutting assembly 200, located on one side of the main sealing and cutting assembly 100 close to the outlet of the packaging, for cutting the tear notch 20;

[0036] A driving device 300, for driving the main sealing and cutting assembly 100 and the auxiliary sealing and cutting assembly 200 to perform sealing and cutting.

[0037] The main function of the main sealing and cutting component 100 is to perform the sealing and cutting operation, that is, to seal the packaging material to make it a complete package. The secondary sealing and cutting component 200 is located beside the main sealing and cutting component 100, close to the outlet side of the packaged product. It is used to cut the tear notch 20, so that users can more easily tear open the package through the tear notch 20 when opening the package. The driving device 300 provides power to drive the main sealing and cutting component 100 and the secondary sealing and cutting component 200 to perform the sealing and cutting operation.

[0038] In actual operation, when the driving device 300 drives the main sealing and cutting component 100 to seal the packaging material, the driving device 300 simultaneously drives the secondary sealing and cutting component 200 to cut the packaging material being cut by the main sealing and cutting component 100 to form a tear notch 20 on the packaging material, solving the problem that the plastic sealing film 10 of the sealing and cutting machine has no tear notch 20 after the product is plastic-sealed.

[0039] In some embodiments, the secondary sealing and cutting component 200 is fixed to the main sealing and cutting component 100.

[0040] As Figure 8 shown, the secondary sealing and cutting component 200 is arranged between the main sealing and cutting component 100 and the conveyor belt 30; fixing the secondary sealing and cutting component 200 to the main sealing and cutting component 100 can reduce the floor area of the entire sealing and cutting device, make the machine more compact, and facilitate installation and maintenance; the fixed connection between the secondary sealing and cutting component 200 and the main sealing and cutting component 100 can ensure the synchronization of the two during the sealing and cutting process, improving the accuracy and efficiency of sealing and cutting.

[0041] Furthermore, the secondary sealing and cutting component 200 includes a secondary sealing and cutting knife 210, and the front end of the secondary sealing and cutting knife 210 is a rectangular blade.

[0042] As Figure 9 shown, the cross-section of the rectangular blade is rectangular, and its four sides intersect to form four right angles. The rectangular blade is used to form a rectangular tear notch 20.

[0043] Even further, the rectangular blade has serrations.

[0044] As Figure 10 shown, the rectangular blade has serrations. The serrations on the rectangular blade form a weakened line on the plastic sealing film 10 but do not completely cut the plastic sealing film 10, enabling the tear notch 20 not to break away from the plastic sealing film 10. When in use, the tear notch 20 is torn open again, ensuring the integrity of the package.

[0045] Furthermore, the secondary sealing and cutting component 200 further includes a secondary cutting seat 220 that cooperates with the secondary sealing and cutting knife 210.

[0046] The combined use of the secondary sealing cutter 210 and the secondary cutting seat 220 can ensure the precise cutting of the tear notch 20. The secondary cutting seat 220 provides stable support for the secondary sealing cutter 210, ensuring the stability and precision of the blade during high-speed cutting. The design of the secondary cutting seat 220 may allow for quick adjustment of the cutting position and depth to adapt to packaging materials of different sizes and materials.

[0047] Furthermore, the main sealing and cutting assembly 100 includes a main sealing cutter 110 and a main cutting seat 120 that cooperates with the main sealing cutter 110.

[0048] Even further, the secondary sealing cutter 210 is fixed to the main sealing cutter 110, and the secondary cutting seat 220 is fixed to the main cutting seat 120.

[0049] By fixing the secondary sealing cutter 210 and the secondary cutting seat 220 to the main sealing cutter 110 and the main cutting seat 120 respectively, a compact and integrated sealing and cutting device can be achieved, reducing additional components and connections and simplifying the overall structure. This design allows the main sealing cutter 110 and the secondary sealing cutter 210 to work synchronously, ensuring that the sealing and the cutting of the tear notch 20 are completed at the same time, improving production efficiency.

[0050] In some embodiments, the main sealing and cutting assembly 100 further includes a transverse sealing cutter 130 perpendicularly connected to one end of the main sealing cutter 110 and a transverse cutting seat 140 perpendicularly connected to one end of the main cutting seat 120.

[0051] The addition of the transverse sealing cutter 130 enables the sealing and cutting device to perform transverse sealing, which is very useful in applications where multi-directional sealing of the packaging is required. The perpendicular connection of the transverse cutting seat 140 to the main cutting seat 120 provides an additional cutting position, enabling the sealing and cutting device to perform longitudinal and transverse cutting simultaneously, increasing the diversity of the packaging.

[0052] Further, the fixing position of the secondary sealing and cutting assembly 200 on the main sealing cutter 110 is close to the connection between the main sealing cutter 110 and the transverse sealing cutter 130.

[0053] Fixing the secondary sealing and cutting assembly 200 close to the connection between the main sealing cutter 110 and the transverse sealing cutter 130 allows the sealing and cutting machine to be applicable to smaller packages, preventing the secondary sealing and cutting assembly 200 from being disposed outside the package and rendering it ineffective.

[0054] Further, the main sealing cutter 110 and the transverse sealing cutter 130 are integrally formed.

[0055] The integrally formed design can improve the overall structural strength of the sealing cutter, reducing damage or breakage caused by weaknesses at the connection points. The integrally formed sealing cutter reduces the assembly steps in the manufacturing process, can improve production efficiency, and reduce manufacturing costs.

[0056] In some embodiments, the sealing and cutting device for a sealing and cutting packaging machine further includes an upper support frame 400 for supporting the main sealing and cutting knife 110 and a lower support frame 500 for supporting the main cutting seat 120.

[0057] The upper support frame 400 and the lower support frame 500 can provide additional support to ensure that the main sealing and cutting knife 110 and the main cutting seat 120 remain stable during operation. The design of the support frames can disperse the force and reduce the pressure directly acting on the sealing and cutting knife and the cutting seat, thereby improving the durability of the entire sealing and cutting device.

[0058] Furthermore, the main sealing and cutting knife 110 is movably connected to the upper support frame 400 and the main cutting seat 120 is movably connected to the lower support frame 500, and under the action of the driving device 300, the main sealing and cutting knife 110 and the main cutting seat 120 can move away from or close to each other.

[0059] The process of the main sealing and cutting knife 110 and the main cutting seat 120 moving away from or close to each other can cut the packaging material; the driving device 300 can be an electric, pneumatic or hydraulic system to achieve automatic control and improve the operation convenience and production efficiency.
