[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. In this disclosure, by setting up a first motor, a rotating shaft and a convex block, the operator starts the first motor, which will cause the rotating shaft and the convex block to rotate. This will cause the outer surface of the convex block to squeeze and push the two moving blocks, the two movable blocks and the two guide plates to move in opposite directions. At this time, the two springs will be compressed. This operation allows the operator to adjust the distance between the two guide plates, thereby guiding and conveying PE cling film of different sizes, thus increasing the application range of the bag making machine.
[0017] 2. In this disclosure, by setting up a third motor, a round shaft, a long rod, and a round block, the operator starts the third motor, which will cause the round shaft and the long rod to rotate. This causes the inner surface of the long rod to press and push the outer surface of the round block, which in turn causes the round block to drive the entire second protective cover, the conveying roller, and the rectangular plate to move upward. This increases the distance between the conveying roller and the movable roller, thereby enabling the operator to convey PE preservation films of different thicknesses, thus bringing convenience to the operator.

[0032] like Figures 1-6 The diagram illustrates a green production bag-making machine for PE cling film according to an embodiment of this disclosure. It includes a worktable 1, with a protective cover 2 fixedly connected to the left side of the bottom end of the worktable 1. A first motor 3 is fixedly installed inside the protective cover 2. A rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. The top end of the rotating shaft 4 passes through the protective cover 2 and extends to the outside of the top end of the protective cover 2, with a protruding block 5 fixedly sleeved on its outer surface. The outer surface of the rotating shaft 4 is movably connected to the inside of the top end of the protective cover 2. The top end of the worktable 1... Guide plates 6 are movably connected in both the front and rear directions. The bottom end of the guide plate 6 is fixedly connected to a movable block 7 located inside the worktable 1. There are two movable blocks 7. The outer surfaces of the two movable blocks 7 are movably connected to the interior of the worktable 1. The bottom end of the two movable blocks 7 is fixedly connected to a moving block 8. The bottom end of the moving block 8 passes through the worktable 1 and extends to the outside of the bottom end of the worktable 1, and its outer surface is movably connected to the interior of the worktable 1. Springs 9 are fixedly connected to the opposite sides of the two movable blocks 7. The other end of the springs 9 is fixedly connected to the interior of the worktable 1.
[0033] The design of the two guide plates 6 can guide the plastic wrap, the design of the two movable blocks 7 can stabilize the movement of the two guide plates 6, and the design of the two springs 9 can effectively reset the subsequent movement of the two movable blocks 7.
[0034] In some examples, table legs 10 are fixedly connected to the four corners of the bottom of the workbench 1. There are four table legs 10, and the four table legs 10 are the same size.
[0035] The design of the four table legs 10 provides excellent support for the entire workbench 1.
[0036] In some examples, a connecting frame 11 is fixedly connected to the right side of the top of the workbench 1. A pneumatic cylinder 12 is fixedly installed at the top of the connecting frame 11. The bottom end of the pneumatic cylinder 12 passes through the connecting frame 11 and extends to the outside of the top of the inner surface of the connecting frame 11, and a cutting blade 13 is fixedly connected thereto.
[0037] Thanks to the design of the cutting blade 13, the plastic wrap can be cut in the subsequent process.
[0038] In some examples, the front and rear ends of the cutting blade 13 are fixedly connected to limiting blocks 14 located inside the front and rear sides of the connecting frame 11, and the outer surface of the limiting blocks 14 is movably connected to the interior of the connecting frame 11.
[0039] The design of the two limiting blocks 14 makes the cutting blade 13 more stable during subsequent movement.
[0040] In some examples, a connecting plate 15 and a limiting block 14 are fixedly connected to the front and back directions of the top left side of the workbench 1, respectively. A rectangular plate 16 is movably connected inside the limiting block 14. The other end of the rectangular plate 16 extends to the front of the outer surface of the limiting block 14 and is fixedly connected to a conveying roller 17. The front of the conveying roller 17 is movably connected to the back of the connecting plate 15.
[0041] The design of the rectangular plate 16 prevents the conveyor roller 17 from falling off.
[0042] In some examples, a second protective cover 18 is movably connected to the front of the connecting plate 15, and a second motor 19 is fixedly installed inside the second protective cover 18.
[0043] Due to the design of the second protective cover 18, the outer surface of the second motor 19 can be prevented from being rubbed during subsequent movements.
[0044] In some examples, the other end of the output shaft of the second motor 19 is fixedly sleeved with a rotating shaft 20. The other end of the rotating shaft 20 passes through the second protective cover 18 and the connecting plate 15 in sequence and extends to the front of the conveying roller 17 and is fixedly connected to the front of the conveying roller 17. The outer surface of the rotating shaft 20 is movably connected to the interior of the connecting plate 15.
[0045] Since both the outer surface of the rotating shaft 20 and the interior of the connecting plate 15 are smooth, friction will be reduced when the rotating shaft 20 rotates inside the connecting plate 15.
[0046] In some examples, a third protective cover 21 is fixedly connected to the top of the left side of the workbench 1, and a third motor 22 is fixedly installed inside the third protective cover 21.
[0047] Due to the design of the No. 3 protective cover 21, the third motor 22 can be protected from dust.
[0048] In some examples, the other end of the output shaft of the third motor 22 is fixedly sleeved with a round shaft 23, the other end of the round shaft 23 passes through the third protective cover 21 and extends to the outside of the third protective cover 21, and a long rod 24 is fixedly sleeved on its outer surface. The outer surface of the round shaft 23 is movably connected to the inside of the third protective cover 21, and a round block 25 is movably connected to the inside of the long rod 24. The back of the round block 25 is fixedly connected to the front of the second protective cover 18.
[0049] Because the inside of the long rod 24 is hollow, it has a limiting effect on the movement of the circular block 25.
[0050] In some examples, a movable roller 26 located directly below the conveyor roller 17 is movably connected to the left side inside the worktable 1, with the top of the movable roller 26 passing through the worktable 1 and extending to the outside of the top of the worktable 1.
[0051] Due to the design of the movable roller 26, it plays an auxiliary sliding role in the subsequent movement of the PE preservation film.
[0052] Working principle and usage process of this utility model:
[0053] First, the operator starts the third motor 22 and the first motor 3. The operation of the third motor 22 will cause the round shaft 23 and the long rod 24 to rotate, so that the inner surface of the long rod 24 will press and push the outer surface of the round block 25. In turn, the round block 25 will drive the second protective cover 18 and the conveying roller 17 to move upward. This will make the distance between the conveying roller 17 and the movable roller 26 meet the thickness of the PE cling film that the operator needs to cut. The operation of the first motor 3 will cause the rotating shaft 4 and the convex block 5 to rotate, so that the outer surface of the convex block 5 will press and push the outer surface of the two moving blocks 8. This will cause the two moving blocks 8 to drive the two movable blocks 7 and the two guide plates 6 to move in opposite directions. At this time, the two springs 9 will be in a compressed state, so that the two guide plates 6 can be adjusted to guide cling film of different sizes. Then, the operator puts one end of the finished PE cling film between the conveying roller 17 and the movable roller 26.
[0054] Finally, the operator starts the second motor 19 and the pneumatic cylinder 12. The operation of the second motor 19 causes the rotating shaft 20 and the conveying roller 17 to rotate, thereby enabling the conveying roller 17 and the movable roller 26 to convey the plastic wrap to the right. The operation of the pneumatic cylinder 12 will cause the cutting blade 13 to move downward, thereby enabling the plastic wrap to be cut.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
