[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] like Figures 1 to 6 As shown, an embodiment of this utility model provides an adjustable-size food packaging bag making machine, including a bag making machine body 1, a hot-melt mechanism and a cutting mechanism are provided on the bag making machine body 1, an adjustment mechanism is provided between the hot-melt mechanism and the cutting mechanism, two conveyor belts 19 are provided on the bag making machine body 1, and a feeding mechanism is provided on the bag making machine body 1.

[0028] In this embodiment of the utility model, the operator controls the hot-melt mechanism and the cutting mechanism through the bag making machine body 1 to make food packaging bags. The packaging bags are squeezed and conveyed by two conveyor belts 19, so that the packaging bags are moved to the unloading mechanism.

[0029] Figures 1 to 6 As shown, the adjustment mechanism includes a pair of electric telescopic rods 8 mounted on the heat-melting mechanism. Each electric telescopic rod 8 is equipped with a connecting component, and a movable heating strip 12 is mounted on the connecting component. A toggle component is mounted on the movable heating strip 12. The heat-melting mechanism includes a force-bearing plate 2 fixedly mounted on the bag-making machine body 1, and a fixed plate 3 fixedly mounted on the bag-making machine body 1. A hydraulic cylinder 4 is fixedly mounted on the fixed plate 3, and a movable plate 5 is fixedly mounted on the telescopic end of the hydraulic cylinder 4. A fixed heating strip 7 is fixedly mounted on the movable plate 5, and a sliding groove 6 is formed on the movable plate 5. The connecting component includes components fixedly mounted on the electric telescopic rods. The telescopic end has a connecting strip 9, on which a long rod 10 is fixedly installed. A slider 11 that is slidably connected to the sliding groove 6 is fixedly installed on the long rod 10, and the slider 11 is fixed to the movable heating strip 12. The actuating component includes a support frame 13 fixedly installed on the movable heating strip 12. Two abutment bolts 14 are threadedly installed on the support frame 13. Each abutment bolt 14 is fixedly installed with a limit block 15. The cutting mechanism includes a rotating rod 16 set on the bag making machine body 1. Two blades 17 are slidably installed on the rotating rod 16. Each blade 17 is symmetrically fixedly installed with two ring shells 18 that are slidably connected to the limit block 15.

[0030] In this embodiment of the utility model, the operator controls the telescopic end of the electric telescopic rod 8 to move, so that the telescopic end of the electric telescopic rod 8 drives the movable heating strip 12 to move through the connecting strip 9, the long rod 10 and the slider 11. The slider 11 moves along the inner side of the sliding groove 6, so that the movable heating strip 12 drives the blade 17 to move through the support frame 13, the abutment bolt 14, the limiting block 15 and the ring shell 18. This makes it easy to adjust the hot melting equipment and the cutting equipment, so as to make food packaging bags of different specifications.

[0031] The fixed heating strip 7 and the movable heating strip 12 are controlled to perform heating work, and the extension end of the hydraulic cylinder 4 is controlled to extend, so that the extension end of the hydraulic cylinder 4 drives the fixed heating strip 7 and the movable heating strip 12 through the movable plate 5 to cooperate with the force plate 2 to perform heat melting work on the packaging bag;

[0032] The rotating rod 16 of the bag making machine body 1 is controlled to rotate, which drives the blade 17 to rotate, thereby enabling the cutting of the hot-melted food packaging bag. When the blade 17 rotates, it drives the ring shell 18 and the limiting block 15 to move. The operator can turn the abutment bolt 14 to cause the limiting block 15 to separate from the ring shell 18 under the thread support of the support frame 13, thereby facilitating the disassembly of the blade 17.

[0033] Figures 1 to 6 As shown, the feeding mechanism includes a feeding shell 20 fixedly installed on the bag making machine body 1, a loading shell 21 fixedly installed on the feeding shell 20, and a limit component provided on the feeding shell 20. The limit component includes a drive motor 22 fixedly installed on the feeding shell 20, a bidirectional lead screw 23 fixedly installed on the output end of the drive motor 22, two threaded bars 24 threadedly installed on the bidirectional lead screw 23, and a support rod 25 slidably connected to the feeding shell 20 fixedly installed on each threaded bar 24. A limit plate 26 slidably connected to the feeding shell 20 is fixedly installed on the support rod 25.

[0034] In this embodiment of the utility model, the operator controls the drive motor 22 to operate according to the specifications of the food packaging bag to make the output end of the drive motor 22 rotate, which drives the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 uses the thread action to drive the limiting plate 26 to move through the threaded strip 24 and the support rod, thereby limiting the feeding of the food packaging bag and enabling the food packaging bag to move accurately into the inner side of the loading shell 21, which facilitates the feeding work.

[0035] Working principle: The operator controls the extension end of the electric telescopic rod 8 to move it. The extension end of the electric telescopic rod 8 drives the movable heating strip 12 through the connecting strip 9, the long rod 10 and the slider 11. The slider 11 moves along the inner side of the sliding groove 6, and the movable heating strip 12 drives the blade 17 through the support frame 13, the abutment bolt 14, the limit block 15 and the ring shell 18 to move it. This adjusts the hot-melt equipment and the cutting equipment. The bag making machine body 1 controls the hot-melt mechanism and the cutting mechanism to make food packaging bags. The two conveyor belts 19 squeeze and transport the made packaging bags to the unloading mechanism. According to the specifications of the made food packaging bags, the drive motor 22 is controlled to run. The output end of the drive motor 22 rotates, which drives the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 uses the thread action to drive the limit plate 26 through the threaded strip 24 and the support rod to move it, limiting the unloading of the food packaging bags and ensuring that the made food packaging bags can be accurately moved into the inner side of the loading shell 21.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
