[0002] Ziplock bags are also called dense bags, bone bags, sealed bags, zipper bags, and keel bags. They are a kind of resealable plastic bags made of polyethylene (LDPE) and high-pressure linear polyethylene (LLDPE) through film blowing and hot cutting machine bags. Common materials include PE\PO\EVA, multi-layer composite zipper bags, etc. Ziplock bags can be used for internal and external packaging of various small items (ornaments, small hardware, toys). Ziplock bags produced with food-grade raw materials can store various small foods, tea, seafood, etc., which are moisture-proof, odor-proof, waterproof, insect-proof, and prevent things from scattering; Ziplock bags can also be used for packaging of clothing and other daily necessities, and have a wide range of uses.

[0003] The ziplock bag is slit by a roller cutter and then sealed by heat sealing.

[0024] First, the bottom of the first slide 3 and the second slide 4 are slidably connected to the slide rail 5 through the slider 13, and the slider 13 and the slide rail 5 are adapted for use. The first slide 3 and the second slide 4 are slidably connected to the slide rail 5 through the slider 13, so that the first slide 3 and the second slide 4 can move forward and backward, and then drive the mounting frame 9 to move forward and backward.

[0025] Furthermore, first limit blocks 14 are installed at both front and rear ends of the slide rail 5. The first limit blocks 14 are fixedly connected to the adjustment seat 2 by screws. A rubber buffer pad is fixedly connected to the inner side of the first limit block 14. When the first slide seat 3 and the second slide seat 4 move forward and backward, the first limit block 14 can prevent the first slide seat 3 and the second slide seat 4 from slipping off the slide rail 5. At the same time, the rubber buffer pad can protect the first slide seat 3 and the second slide seat 4, thereby improving the protection of the first slide seat 3 and the second slide seat 4.

[0026] Then, the left and right ends of the back side of the mounting plate 10 are fixedly connected to the mounting frame 9 through the fixing seat 15, a first mounting seat 16 is installed in the middle of the front side of the mounting plate 10, and the second mounting seats 17 are installed on the left and right ends of the front side of the mounting plate 10, a cylinder 18 is installed on the inner side of the first mounting seat 16, and a slide bar 19 is installed on the inner sides of the two groups of second mounting seats 17, and the slitting knife body 11 and the heat sealing knife body 12 are installed below the first mounting seat 16 and the second mounting seat 17.

[0027] Secondly, the cylinder 18 is fixedly installed on the inner side of the first mounting seat 16, and the driving end of the cylinder 18 and the bottom end of the slide rod 19 are fixedly connected to the slitting knife body 11 and the heat sealing knife body 12 by bolts. The slitting knife body 11 and the heat sealing knife body 12 are provided with waist-shaped holes 20 at the positions corresponding to the bolts. The slitting knife body 11 and the heat sealing knife body 12 are fixedly installed with the cylinder 18 and the slide rod 19 by bolts, so that when the slitting knife body 11 and the heat sealing knife body 12 need to be disassembled, replaced or repaired, the bolts can be unscrewed for disassembly and assembly.

[0028] Finally, the two groups of slide rods 19 are slidably connected to the second mounting seat 17 through the slide sleeve 21, and the top of the two groups of slide rods 19 are installed with a second limit block 22. When the cylinder 18 drives the slitting knife body 11 and the heat sealing knife body 12 to perform slitting and sealing operations, the bottom end of the slide rod 19 is connected to the two ends of the slitting knife body 11 and the heat sealing knife body 12, and then the slide rod 19 slides in the slide sleeve 21 to improve the stability of the operation of the slitting knife body 11 and the heat sealing knife body 12.

[0029] In this embodiment, the implementation scenario is specifically as follows: two groups of support frames 1 are installed on both sides of the ziplock bag conveyor line, and the support frames 1 provide support for the adjustment seat 2. According to the processing requirements of different specifications, the motor 6 is started to drive the gear 8 to rotate, so that the gear 8 rolls on the rack 7, thereby driving the first slide 3 and the second slide 4 to move back and forth on the adjustment seat 2. Under the action of the slide rail 5, the first slide 3 and the second slide 4 slide back and forth on the adjustment seat 2, thereby driving the mounting frame 9 to move back and forth, and the positions of the slitting knife body 11 and the heat sealing knife body 12 are adjusted respectively by adjusting the positions of the two groups of mounting frames 9. The utility model can improve the overall adjustability of the roller cutter structure for ziplock bags through design, and can process ziplock bags of different lengths according to processing requirements of different specifications, and at the same time, the degree of automation is higher, and the slitting knife body 11 and the heat-sealing knife body 12 can be disassembled from the front of the mounting plate 10 by bolts, so that the slitting knife body 11 and the heat-sealing knife body 12 can be replaced or repaired conveniently.
