[0002] Plastic packaging bag laminating machine is a kind of mechanical equipment, which is mainly used to cover the surface of plastic packaging bags with a layer of transparent plastic film. The plastic film and packaging bag are combined by heat pressing to achieve the purpose of protecting the surface of the raw materials and increasing the gloss. After the lamination is completed, the packaging bags need to be cut and separated into individual pieces.

[0003] The cutting structure of the currently used laminating machine may cause the cutting position to deviate from the predetermined trajectory when cutting the packaging bag because it cannot be effectively fixed during the cutting process, thereby affecting the cutting accuracy. Inaccurate cutting is often accompanied by material waste.

[0024] The blocking mechanism 11 includes a movable frame 111. Both sides of the surface of the movable frame 111 are respectively slidably connected to two inner walls of one side surface of the knife seat 7. When the push blocks 10 on both sides are lowered to a suitable position, the movable frame 111 can be moved.

[0026] It is worth noting that the technical features such as the transmission component 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: When the cutter 6 descends to cut the packaging bag, the fixing plates 8 on both sides can be driven down when the mounting plate 5 descends. When the fixing plate 8 descends, the tension springs 91 on both sides can be driven down, and then the tension springs 91 on both sides descend to drive the movable rods 92 on both sides to descend. Next, the movable rods 92 on both sides descend to drive the positioning plates 93 to descend. When the positioning plates 93 on both sides descend and contact the top of the workbench 1, the two sides of the packaging bag can be limited. When the mounting plate 5 continues to descend, the tension springs 91 can be stretched. When the cutter 6 descends to cut the packaging bag, the cutting effect of the packaging bag can be better. At the same time, when the mounting plate 5 descends, the push blocks 10 on both sides can be driven down. Then, when the push blocks 10 on both sides descend to the appropriate position, the movable frame 111 can be moved. Next, the movement of the movable frame 111 can compress the compression springs 112. When the movable frame 111 moves The telescopic rod 113 can be retracted, and then the movement of the movable frame 111 can drive the movable plate 114 to move, and then the movement of the movable plate 114 can drive the blocking block 115 to move. When the blocking block 115 moves out of the interior of the ventilation hole 13, the debris inside the V-shaped groove of the knife seat 7 can enter the interior of the mounting groove 12 through the ventilation hole 13 under the action of the fan 152, and then the debris inside the mounting groove 12 can enter the interior of the pipe rack 153, and then the debris inside the pipe rack 153 can enter the interior of the collection box 14. Under the action of the filter plate 154, the debris inside the collection box 14 can be prevented from being discharged through the ventilation plate 151. When the cutter 6 completes cutting and the mounting plate 5 rises, the pushing blocks 10 on both sides can be raised. When the pushing blocks 10 on both sides rise and release the contact with the movable frame 111, the blocking block 115 can be entered into the interior of the ventilation hole 13 under the action of the compression spring 112, and so on.
