specific Embodiment 1

[0024]Specific embodiment one: the present invention proposes a plastic packaging bag opening sealing device, comprising a master disc 1, a male disc 2, and a cutter disc 3, both of which have a fan-shaped structure with a central angle of 120°. The master disc 1 and the male disc 2 are hinged to each other near the center of the circle, and the master disc 1 is provided with an arc-shaped hollowed-out female sipe at the center of the fan-shaped structure of the master disc 1 near the arc edge. 11. The central angle of the female sipes 11 is 110°, the two ends of the female sipes 11 are respectively provided with hollowed-out stop grooves 12, and the said stop grooves 12 communicate with the female sipes 11. Between the female sipe 11 and the arc-shaped edge of the master disc 1, there is an arc-shaped external pressure groove 13 concentric with the fan-shaped structure of the master disc 1. The central angle of the external pressure groove 13 is 90°-120°. The inner side of th...

specific Embodiment 2

[0029] Specific embodiment two: its structure is the same as specific embodiment one. The method of use is as follows:

[0030] Push the cutter head 3 to the side of the high solid beam 271, make the high clamping groove 331 snap into the high solid beam 271, pinch the upper connection part 31 with your hands, open the clip bar 272, and separate the high fixer 27 and the male plate 21 , then pinch the upper connection portion 31 and the high holder 27 respectively, and finally take out the whole cutter head 3 . Put the high card slot 331 of the new cutter head 3 on the high solid beam 27 along the original direction, put the cutting part 33 into the knife stop hole 22 on the side of the high fixer 27, and place it on the male disk along the guide piece 323 2 surface, the clamping portion 32 penetrates into the knife stop hole 22, and engages the clamping strip 272 again. Complete the replacement of the new cutterhead 3.

specific Embodiment 3

[0031] Specific embodiment three: its structure is the same as specific embodiment one. The method of use is as follows:

[0032] Open the opening process without cutting on the plastic bag: push out the cutter head 3 in the self-stop box 25, clamp the plastic bag to be opened between the male disk 2 and the female disk 1, and clamp the male disk 2 and the female disk 1, Utilize external pressure groove 13, internal pressure groove 14 and external pressure protrusion 23, internal pressure protrusion 24 to make the plastic bag exposed by male knife groove 21 and female knife groove 11 tight. The sharp tip of 331 will pierce a circular opening in the plastic bag. After the male disk 2 and the female disk 1 are pressed together, push the cutter head 3 to cut according to the size and direction of the desired opening.

Description

technical field [0001] The invention relates to the field of cutting plastic products, in particular to an opening sealing device for plastic packaging bags. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life. Because of its good sealing, corrosion resistance and airtightness, it is widely used in daily life and industrial production, especially widely Applied to small food packaging, so that the food in the package can effectively prevent moisture and humidity. Generally, the small food plastic packaging bag is provided with a gap for tearing the plastic packaging bag on its bag body, and the plastic bag can be easily opened by using this gap. However, in the process of tearing the plastic packaging bag, due to the direction of force and the If the size is not uniform, it is very easy for the tearing of the packaging bag to be unplanned, too large, or too small, and the ...
