[0026] refer to Figure 2 and 3 Detailed explanation of the structure of environmentally friendly packaging bags:

[0027] An environmentally friendly packaging bag includes a bottom 11 for supporting materials, a perimeter 12 fixedly connected to the bottom 11, which gathers and loads the materials supported by the bottom 11. Two carrying straps 14 are fixedly connected to the perimeter 12, allowing the object to be lifted. Two metal wires 13 are fixedly connected to the perimeter 12. When loading items, the two metal wires 13 are twisted to support the perimeter 12, allowing the bag to automatically open for easy loading. Metal coils are fixedly connected to the edge of the bottom 11, supporting the edge of the bag and shaping the bottom to prevent deformation that could affect loading. The folded perimeter 12 also makes it easier to store when not in use.

[0028] In conjunction with the above embodiments, the following functions can also be achieved;

[0029] refer to Figure 1 The following details the implementation process for preparing environmentally friendly packaging bags:

[0030] The preparation method includes the following steps:

[0031] Step 1: Process the bottom 11 of the packaging bag for load-bearing, and fix a metal coil to the bottom 11 of the packaging bag for shaping to prevent deformation when loading materials and affecting the loading of materials;

[0032] Step 2: The folded packaging bag is folded to create the perimeter 12, which saves space during storage;

[0033] Step 3: Fix two metal wires 13 to the periphery 12 of the packaging bag. The two metal wires 13 can support the periphery 12 of the packaging bag, which is convenient for loading materials. Fix two carrying ropes 14 to the periphery 12 of the packaging bag, which can lift the environmentally friendly packaging bag by pulling the two carrying ropes 14.

[0034] Step 4: Secure the perimeter 12 of the packaging bag to the bottom 11 of the packaging bag to complete the processing of the environmentally friendly packaging bag.

[0035] In conjunction with the above embodiments, the following functions can also be achieved;

[0036] refer to Figure 4 This document details the process of stamping and folding raw materials to form the perimeter of the packaging bag.

[0037] The device includes multiple lower pressure plates 41 that press the raw material from the bottom to fold it. Each of the lower pressure plates 41 has an upper pressure plate 71 at its upper end. The lower pressure plates 41 and the upper pressure plates 71 can move relative to each other synchronously, approach each other to press the raw material and fold it. The lower pressure plates 41 and the upper pressure plates 71 move away from each other synchronously, leaving the pressing and folding of the raw material, in preparation for the next pressing and folding of the raw material, thereby completing the processing of the periphery 12 of the packaging bag.

[0038] In conjunction with the above embodiments, the following functions can also be achieved;

[0039] refer to Figure 4 and 5 The process of folding the raw material in multiple places by sliding multiple lower pressure plates is described in detail:

[0040] Multiple lower pressure plates 41 are fixedly connected to multiple follower plates 42. The multiple follower plates 42 are all fixedly connected to the lifting frame 31. Multiple cylinders I 32 are fixedly connected to the lifting frame 31. The cylinder rods of the multiple cylinders I 32 are fixedly connected to the corresponding lower pressure plates 41. When the multiple cylinders I 32 are activated, the cylinder rods of the multiple cylinders I 32 drive the multiple follower plates 42 to slide. The multiple follower plates 42 drive the multiple lower pressure plates 41 to slide. Thus, in coordination with the lifting and lowering of the multiple lower pressure plates 41, the raw materials at different positions are folded and stamped to complete the folding processing of the raw materials.

[0041] In conjunction with the above embodiments, the following functions can also be achieved;

[0042] refer to Figure 5 and 6 The following details the implementation process of driving the lifting and lowering of multiple lower pressure plates:

[0043] The lifting frame 31 is slidably connected to the base 21. Multiple cylinders II 22 are fixedly connected to the base 21 by bolts. The cylinder rods of the multiple cylinders II 22 are fixedly connected to the bottom of the lifting frame 31. When the multiple cylinders II 22 are started, the cylinder rods of the multiple cylinders II 22 drive the lifting frame 31 to rise and fall. The lifting frame 31 drives multiple follower plates 42 to rise and fall. The multiple follower plates 42 drive multiple lower pressure plates 41 to rise and fall, thereby realizing the stamping of the lower end of the raw material.

[0044] In conjunction with the above embodiments, the following functions can also be achieved;

[0045] refer to Figure 6 and 7 The following details the implementation process of stamping and folding the raw materials:

[0046] A gear ring I 23 is rotatably connected to the base 21 via bearings. A turntable 24 is fixedly connected to the gear ring I 23. The turntable 24 can fix and support the raw material, facilitating the stamping and folding of the raw material. It can also drive the turntable 24 to rotate through the rotation of the gear ring I 23, thereby facilitating the simultaneous stamping and folding of the raw material by multiple lower pressure plates 41 and multiple upper pressure plates 71. A drive wheel I 25 is rotatably connected to the base 21. The drive wheel I 25 and the gear ring I 23 mesh and drive each other. The drive wheel I 25 is fixedly connected to the output shaft of the geared motor I. The geared motor I is fixedly connected to the base 21 by bolts. When the geared motor I is started, it drives the drive wheel I 25 to rotate, thereby meshing and driving the gear ring I 23 to rotate, which in turn drives the turntable 24 to rotate, thus facilitating the folding process of the raw material.

[0047] In conjunction with the above embodiments, the following functions can also be achieved;

[0048] refer to Figure 4 and 11 The following details the process of stamping and folding the upper part of the raw material:

[0049] Multiple upper pressure plates 71 are fixedly connected to the cylinder rods of multiple cylinders III, which are fixedly connected to multiple feed frames 63. Each upper pressure plate 71 has two guide rods 72 fixedly connected to it. The guide rods 72 are slidably connected to the corresponding feed frames 63. When the cylinders III are activated, the cylinder rods of the cylinders III drive the upper pressure plates 71 to rise and fall, thereby realizing the stamping and folding of the raw materials by the upper pressure plates 71. Each guide rod 72 is fixedly connected to the corresponding feed frame 63 with a tension spring. The tension spring can buffer the rising and falling upper pressure plates 71, thereby preventing the upper pressure plates 71 from moving too fast and causing the stamping and folding of the raw materials to be unqualified.

[0050] In conjunction with the above embodiments, the following functions can also be achieved;

[0051] refer to Figure 9 and 10 The following details the implementation process of driving the sliding of multiple upper pressure plates:

[0052] Multiple feed frames 63 are slidably connected to the ring frame 61, the ring frame 61 is fixedly connected to the upright frame 51, and the upright frame 51 is fixedly connected to the base 21. By driving the multiple feed frames 63 to slide, multiple upper pressure plates 71 can slide. The multiple upper pressure plates 71 and multiple lower pressure plates 41 slide synchronously, so that the raw materials at different positions can be folded and stamped synchronously.

[0053] In conjunction with the above embodiments, the following functions can also be achieved;

[0054] refer to Figure 8 and 9 The following details the implementation process of driving multiple feed frames to slide:

[0055] Multiple gear sleeves 62 are rotatably connected to the ring frame 61, and each gear sleeve 62 is fixedly connected to a lead screw sleeve. The multiple lead screw sleeves drive the corresponding feed frame 63 to slide through the threads. A ring rack 52 is rotatably connected to the upright frame 51. The multiple gear sleeves 62 mesh with the ring rack 52 for transmission. When the ring rack 52 rotates, it meshes and drives the multiple gear sleeves 62 to rotate. The rotation of the multiple gear sleeves 62 drives the multiple feed frames 63 to slide, thereby adjusting the position of the multiple upper pressure plates 71 and completing the stamping and folding processing of raw materials at different positions.

[0056] In conjunction with the above embodiments, the following functions can also be achieved;

[0057] refer to Figure 8 The following details the implementation process of driving the ring rack to rotate:

[0058] A gear ring II is fixedly connected to the annular rack 52, and a drive wheel II 53 is rotatably connected to the upright frame 51. The drive wheel II 53 meshes with the gear ring II for transmission. The drive wheel II 53 is fixedly connected to the output shaft of the geared motor II, and the geared motor II is fixedly connected to the upright frame 51. When the geared motor II is started, the geared motor II drives the drive wheel II 53 to rotate, thereby meshing with the drive gear ring II to rotate and drive the annular rack 52 to rotate, realizing the position adjustment of multiple upper pressure plates 71, which facilitates the stamping and folding of raw materials.
