Description

Technical Field

[0001] This utility model relates to the field of heat-sealing lines, and in particular to a heat-sealing line with sealing function. Background Technology

[0002] While conventional dot-type heat-sealing lines offer a smooth finish, their heat-sealing strength is insufficient, and dust or insects can easily get between the two heat-sealing points. On the other hand, conventional linear heat-sealing lines, although offering excellent heat-sealing strength and sealing performance, undergo plastic deformation during cooling, resulting in uneven heating wires that affect aesthetics. Therefore, providing a heat-sealing line that offers strong heat-sealing strength, good sealing performance, is resistant to dust and insects, and is smooth has become an urgent problem to be solved.

[0022] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 2 This utility model provides a heat-sealing line with sealing function, including at least two rows of heat-sealing pattern groups 100. Each heat-sealing pattern group 100 includes multiple heat-sealing patterns arranged at equal intervals. The two rows of heat-sealing pattern groups 100 form a heat-sealing area on the packaging bag. A heat-sealing mark is provided at any position of the heat-sealing area. The gap between adjacent heat-sealing patterns is the outlet or inlet of an air passage. The air passage connects the inner and outer sides of the heat-sealing area on the packaging bag. There is at least one obstruction mark along the length and width of the heat-sealing area from the inlet to the outlet of the air passage.

[0024] When in use, the heat seal is strong due to the barrier of the two rows of heat seal pattern groups 100. The air duct allows gas in the packaging to be discharged, preventing the packaging from bursting due to compression during transportation. At the same time, the blocking marks in the air duct do not affect the airflow, and can effectively prevent dust or insects from entering the packaging bag.

[0025] In this embodiment, the heat-sealing pattern of one row of heat-sealing pattern group 100 is a U-shaped line, and the heat-sealing pattern of the other row of heat-sealing pattern group 100 is a U-shaped line 101; 102, the openings of the heat-sealing patterns of the two rows of heat-sealing pattern groups 100 are arranged opposite to each other.

[0026] In this embodiment, the openings of the U-shaped lines 101 and 102 face the interval between adjacent U-shaped lines.

[0027] In this embodiment, a heat-sealing upper mold 200 and a heat-sealing lower mold 300 are also included. The heat-sealing upper mold 200 is provided with protrusions corresponding to the U-shaped heat-sealing pattern, and the heat-sealing lower mold 300 is provided with protrusions corresponding to the U-shaped lines 101 and 102 heat-sealing patterns.

[0028] In this embodiment, the number of heat-sealing patterns in the two rows of heat-sealing pattern groups 100 is equal, and the first row of heat-sealing pattern groups 100 is located above the second row of heat-sealing pattern groups 100.

[0029] The working principle of this utility model is as follows:

[0030] The two rows of heat-sealing pattern groups 100 provide a strong heat seal, and the air channels allow gas to escape from the packaging, preventing it from bursting during transportation. At the same time, the blocking marks inside the air channels do not affect the airflow, and effectively prevent dust or insects from entering the packaging bag.
