[0029] In this embodiment, when it is needed, the bag making machine body 1 and the conveying device 4 are controlled and started through the setting of the controller 2, and the flat film blowing machine inside the bag making machine body 1 is used for blow molding. The formed film is a cylindrical film, and then the herringbone frame is used to flatten the cylindrical film, and the blown film is continuously stretched out, and then cutting, sealing and other processes are performed to form a plastic bag. After the plastic bag is formed, the plastic bag is transported by the setting of the conveying device 4. When in use, the bag making machine body 1 and the conveying device 4 move downward and drive the plate 51, so that the slide bar 53 slides downward inside the fixed plate 52. Due to the setting of the spring plate 54, the spring 55 is driven to stretch the spring 55.

[0031] In this embodiment, the small ball 522 is arranged in the through hole 521 so that the sliding rod 53 slides and drives the small ball 522 to roll, thereby reducing the generation of friction and having a certain degree of flexibility. Example 3

[0032] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a heat-conducting copper tube 31 is fixedly connected to the interior of the heat dissipation mechanism 3, one side of the heat-conducting copper tube 31 extends to the outside of the heat dissipation mechanism 3, a lower groove 32 is provided inside the heat dissipation mechanism 3, an upper groove 33 is provided at the upper end of the lower groove 32, a semiconductor cooling plate 34 is fixedly connected to the interior of the upper groove 33, one end of the semiconductor cooling plate 34 extends to the interior of the lower groove 32, a heat dissipation through hole 35 is provided inside the heat dissipation mechanism 3, and vents 36 are provided at both ends of the heat dissipation mechanism 3.

The arrangement of the heat dissipation holes 35 makes the semiconductor refrigeration plate 34 itself generate a certain temperature when working, and the temperature is discharged through the heat dissipation holes 35. The arrangement of the vents 36 makes the internal air flow and has the effect of heat dissipation. The two end faces of the semiconductor refrigeration plate 34 are at different positions to achieve the cooling effect.

[0034] The following is a detailed description of the working principle of the plastic bag making machine.

[0035] like Figure 1-4 As shown, when in use, the bag making machine body 1 and the conveying device 4 move downward and drive the plate 51, so that the slide bar 53 slides downward inside the fixed plate 52. Due to the setting of the spring plate 54, the spring 55 is driven, so that the lower surface of the spring plate 54 contacts the elastic rubber block 56 and deforms, thereby having a buffering effect. The heat inside the controller 2 is transferred through the setting of the heat-conducting copper tube 31. The semiconductor refrigeration plate 34 is cooled by the setting of the upper groove 33 and the lower groove 32, so that the cold air in the upper groove 33 cools the heat-conducting copper tube 31 through the cold air, thereby having a heat dissipation effect.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
