Support plates 70 are fixedly connected to the upper and lower sides of the transmission frame 72.
[0039] The above structure, driven by the third motor 73, causes the third drive wheel 74 to rotate. The third drive wheel 74 is externally connected to the third belt 75, and the other end of the third belt 75 is connected to the third driven wheel 76.

A fourth drive wheel 77 is fixedly connected to one side of the third driven wheel 76, and a fourth driven wheel 78 meshes with the lower part of the fourth drive wheel 77. The third driven wheel 76 drives the fourth drive wheel 77 and the fourth driven wheel 78 to rotate in opposite directions. A hot press roller 79 is fixedly connected to the other side of the fourth drive wheel 77 and the fourth driven wheel 78. Under the action of the hot press rollers 79 on both sides, the edges of the two layers of plastic film are heat-fused and bonded together, so that the edges of the two layers of plastic film are fused together.
[0040] The guiding device 8 includes a second bracket 81. A fourth motor 82 is fixedly connected to the upper left side of the second bracket 81. A fifth driving wheel 83 is fixedly connected to the output end of the fourth motor 82. A fourth belt 84 is externally connected to the fifth driving wheel 83.

The guide roller 86 is fixedly connected to the left side of the sixth driven wheel 88.
[0041] The above structure, driven by the fourth motor 82, causes the fifth driving wheel 83 to rotate. The fifth driving wheel 83 is externally connected to the fourth belt 84, and the other end of the fourth belt 84 is connected to the fifth driven wheel 85, so that the fifth driving wheel 83 drives the fifth driven wheel 85 to rotate through the fourth belt 84.
[0042] A guide roller 86 is fixedly connected to the right side of the fifth driven roller 85, and a sixth driving roller 87 is fixedly connected to the other end of the guide roller 86. A sixth driven roller 88 is engaged below the sixth driving roller 87, and a guide roller 86 is fixedly connected to the left side of the sixth driven roller 88. This allows the sixth driving roller 87 to drive the lower guide roller 86 to rotate through the sixth driven roller 88. Under the rotation of the upper and lower guide rollers 86, the plastic film after sealing moves forward.
[0043] The bottom sealing device 9 includes a third bracket 91. Slide frames 92 are fixedly connected to the upper left and right sides of the third bracket 91. A return spring 93 is fixedly connected inside the slide frame 92. A slider 94 is fixedly connected above the return spring 93. A lifting rod 95 is fixedly connected to one side of the slider 94.

[0044] The above structure, driven by the fifth motor 99, causes the rotating rod 910 to rotate. Cams 911 are fixedly connected to the left and right sides of the rotating rod 910. When the protruding end of the cam 911 rotates to the lower position, the protruding end of the cam 911 presses against the lifting rod 95. Under the pressing action of the cam 911, the lifting rod 95 is lowered. A heat melter 96 is fixedly connected to the lower part of the lifting rod 95, so that the lifting rod 95 drives the heat melter 96 to descend synchronously. Under the action of the heat melter 96, the plastic film after the edge sealing is completed is heat-sealed.
[0045] Sliders 94 are fixedly connected to the left and right sides of the lifting rod 95, and a return spring 93 is fixedly connected to the bottom of the sliders 94. This causes the lifting rod 95 to drive the sliders 94 to descend synchronously. At this time, the return spring 93 extends and retracts. When the protruding end of the cam 911 rotates to the top, the return spring 93 causes the lifting rod 95 to rise, which in turn causes the lifting rod 95 to drive the hot melter 96 to rise synchronously.
[0046] The conveying device 10 includes a conveying platform 101. A sixth motor 102 is fixedly connected to the left side of the conveying platform 101.

Cams 911 are fixedly connected to the left and right sides of the rotating rod 910.
[0047] The above structure, driven by the sixth motor 102, causes the active roller 103 to rotate. The active roller 103 is externally connected to a conveyor belt 104, and the other end of the conveyor belt 104 is connected to a driven roller 106. Under the drive of the active roller 103 and the support of the driven roller 106, the conveyor belt 104 rotates.
[0048] Driven by the fifth motor 99, the rotating rod 910 rotates, and cams 911 are fixedly connected to the left and right sides of the rotating rod 910. When the protruding end of the cam 911 rotates to the lower position, the protruding end of the cam 911 presses against the lifting rod 95. Under the pressing action of the cam 911, the lifting rod 95 is lowered. The blade 107 is fixedly connected to the lower part of the lifting rod 95, so that the lifting rod 95 drives the blade 107 to descend synchronously. Under the action of the blade 107, the plastic bag after the bottom sealing is completed is cut.
[0049] By providing a support roller 105, which is located inside the conveyor table 101 and rotatably connected to the conveyor table 101, the support roller 105 provides reverse support to the blade 107, making it easier for the blade 107 to cut the plastic bag.
[0050] Working Principle: This type of plastic packaging bag production laminating machine first adds raw material into the feeding funnel 54. Under the action of the laminating device 5, the raw material forms a film. The film is then guided above the first cooling roller 18 and the second cooling roller 19. Under the action of the first cooling roller 18 and the second cooling roller 19, the film is shaped. The shaped film is then passed through the support roller 20 and into the merging device 6. Under the action of the merging device 6, the two layers of plastic film are initially merged and aligned. The two initially merged layers of plastic film are then guided into the edge sealing device 7. Under the action of the hot press roller 79, the edges of the two layers of plastic film are heat-fused together. At this point, the blowing air is turned on. After the sealing process, the machine 22 cools the plastic film. Then, the sealed plastic film is guided into the guide device 8. Guided by the guide device 8, the sealed plastic film moves forward and is then guided into the bottom sealing device 9. The bottom sealing device 9 seals the bottom of the sealed plastic film. The sealed plastic film is then guided into the conveyor device 10. The cutter 107 cuts the double-layered plastic film. After cutting, the plastic bag is conveyed by the conveyor belt 104 and introduced into the collection bin 2, thus completing the production of the plastic bag.
