[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A plastic film packaging machine that is easy to maintain includes a base 1, a sealed rear shell 2 fixed on the upper side of the base 1, a side baffle 4 fixed on one side of the sealed rear shell 2, a bottom slide rail 5 fixed on the upper side of the base 1, a movable front shell 3 slidably connected on the bottom slide rail 5, and a limit mechanism 6 fixed on the base 1.

[0022] The limiting mechanism 6 includes a support base 63 fixed on the upper side of the base 1. An outer fixing ring 61 is fixed on the support base 63. An inner fixing ring 66 is fixed inside the outer fixing ring 61. An arc-shaped baffle 62 is slidably connected in the interlayer between the inner fixing ring 66 and the outer fixing ring 61. An installation groove is opened in the support base 63. A return spring 64 is fixed in the installation groove. A limit pin 65 is fixed on the upper side of the return spring 64.

[0023] In an optional embodiment, a tenon strip 8 is fixed to the front side of the sealed rear shell 2, and a tenon groove 9 matching the shape and size of the tenon groove 9 is opened on the side of the movable front shell 3 near the sealed rear shell 2. A cylindrical slide rod 7 is fixed to the bottom of the movable front shell 3. The cylindrical slide rod 7 is slidably installed in the bottom slide rail 5, and one end of the bottom slide rail 5 extends to the inner side of the inner fixing ring 66. The outer circumferential surfaces of the outer fixing ring 61, the inner fixing ring 66, and the cylindrical slide rod 7 are all provided with cylindrical grooves for the limit pin 65 to pass through. The outer circumferential surface of the outer fixing ring 61 is provided with an arc-shaped through groove. A lever is fixed to one side of the arc-shaped baffle 62. The lever is slidably installed in the arc-shaped through groove. The position of the arc-shaped baffle 62 can be adjusted by the lever, thereby adjusting the limiting state of the limit pin 65.

[0024] In an optional embodiment, an L-shaped support plate 10 is fixedly fixed on one side of the sealed rear shell 2, and an L-shaped docking plate 11 that is slidably connected to the L-shaped support plate 10 is fixed inside the movable front shell 3. A sealing strip is provided on the side of the L-shaped docking plate 11 that is close to the L-shaped support plate 10. By setting the sealing strip, the heat leakage is reduced when the plastic film packaging machine heats the packaging.

[0025] In an optional embodiment, the upper side of the bottom slide rail 5 is open, and a circular groove is provided inside the bottom slide rail 5 for the cylindrical slide rod 7 to slide.

[0026] Working Principle: The heat-sealing part of existing plastic film packaging machines is usually a closed cavity, which is generally integrally formed or fixed by bolts. Disassembly and assembly are difficult during inspection and maintenance. In this embodiment, during installation, the tenon groove 9 is aligned with the tenon strip 8, and the cylindrical slide rod 7 is aligned with the circular slide groove in the bottom slide rail 5. This allows the movable front shell 3 to slide on the front side of the sealed rear shell 2, so that the movable front shell 3 directly contacts the side baffle 4. This allows the cylindrical slide rod 7 to enter the inner side of the inner fixing ring 66. Then, the toggle block is moved, causing the arc baffle 62 to move to the upper side of the interlayer between the outer fixing ring 61 and the inner fixing ring 66, thereby releasing the limit pin 65. The return spring 64 returns to its original position, allowing the limit pin 65 to pass through the outer fixing ring 61 and the inner fixing ring 66 and enter the cylindrical slide rod 7, thereby limiting the cylindrical slide rod 7 and fixing it. This achieves the function of quick disassembly and assembly of the movable front shell 3.
