Figure 1 An embodiment of this utility model provides a paper feeding rack winding tension adjustment device for a kraft paper roll packaging machine, comprising a mounting base plate 6, mounting tubes 20 installed on both sides of the top wall of the mounting base plate 6, first vertical plates 2 detachably installed in the inner cavity of the two sets of mounting tubes 20, first adjusting wheels 1 rotatably connected to the top of the inner wall of the two sets of first vertical plates 2, sliding tubes 10 movably sleeved on the outer wall of the two sets of first vertical plates 2, flat plates 14 fixed on the outer wall of the two sets of sliding tubes 10, a second vertical plate 12 fixed at the middle position of the top wall of the flat plate 14, and a second adjusting wheel 13 rotatably connected to the top of the outer wall of the second vertical plate 12.
[0026] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A vertical moving assembly is installed at the middle position of the top wall of the mounting base plate 6. The vertical moving assembly includes a mounting plate 15, which is set on the top wall of the mounting base plate 6. The cross-section of the mounting plate 15 is arc-shaped. A nut 9 is fixed at the top position of the inner wall of the mounting plate 15. A threaded rod 11 is threaded through the inner cavity of the nut 9. A handle 7 is fixed at the bottom position of the threaded rod 11. The top position of the threaded rod 11 is rotatably connected to the bottom wall of the plate 14 through a bearing.
[0027] The end of the kraft paper is wound around the first adjusting wheel 1 and the second adjusting wheel 13. When the tension of the kraft paper is too low, the operator only needs to turn the handle 7 to drive the threaded rod 11 to rotate. Under the action of the nut 9, the threaded rod 11 can move downward during the rotation, thereby driving the plate 14 to move synchronously. Under the action of the plate 14, the second vertical plate 12 and the second adjusting wheel 13 can move synchronously, thereby adjusting the vertical spacing value of the first adjusting wheel 1 and the second adjusting wheel 13, thus facilitating the adjustment of the tension of the kraft paper.
[0028] Please refer to the attached diagram in the instruction manual. Figure 1 , 3 Both ends of the outer wall of the mounting plate 15 are equipped with connecting plates 17. The top walls of the two sets of connecting plates 17 are provided with first bolts 16 that penetrate the connecting plates 17. The top wall of the mounting base plate 6 is provided with first screw holes 18 that match the threads of the first bolts 16. The bottom end of the outer wall of the first vertical plate 2 is provided with a second screw hole 19. The outer wall of the mounting tube 20 is provided with a second bolt 21 that matches the threads of the second screw hole 19. The top end of the mounting tube 20 is set to be open.
[0029] Tighten the second bolt 21 to separate it from the second screw hole 19, then tighten the first bolt 16 to separate it from the first screw hole 18. Then move the first vertical plate 2 upward to separate it from the mounting tube 20. Then move the plate 14 to separate the slide tube 10 from the first vertical plate 2, making it easy to disassemble and replace the first adjusting wheel 1 and the second adjusting wheel 13.
[0030] Please refer to the attached diagram in the instruction manual. Figure 1 A limiting tube 4 is installed on one side of the top wall of the mounting base plate 6. The top of the limiting tube 4 is open, and a scale plate 3 passes through the top of the limiting tube 4 through its inner cavity. The scale plate 3 has evenly engraved scale lines on its front side wall, and the top of the scale plate 3 is fixed to the bottom wall of the plate 14. When the plate 14 moves up and down, it can drive the scale plate 3 to move synchronously within the inner cavity of the limiting tube 4. The scale markings on the scale plate 3 make it easy for the operator to monitor the distance the plate 14 moves up and down in real time.
[0031] Please refer to the attached diagram in the instruction manual. Figure 1 Multiple sets of movable wheels 8 are fixed to the bottom wall of the mounting base plate 6.

The top of the handle frame 5 is equipped with an anti-slip sleeve. Pushing and pulling the handle frame 5 allows the paper feeding rack and winding tension adjustment device of the kraft paper roll packaging machine to move through the multiple sets of movable wheels 8.
[0032] Working principle: When using the paper feeding rack and winding tension adjustment device of the kraft paper roll packaging machine, the push and pull handle 5 causes the paper feeding rack and winding tension adjustment device of the kraft paper roll packaging machine to move to one side of the paper feeding rack of the kraft paper roll packaging machine through multiple sets of moving wheels 8, and then the end of the conveyed kraft paper is wrapped around the first adjusting wheel 1 and the second adjusting wheel 13.
[0033] When the tension of the kraft paper is too low, the operator only needs to turn the handle 7 to rotate the threaded rod 11. Under the action of the nut 9, the threaded rod 11 can move downward during the rotation, which can drive the plate 14 to move synchronously. Under the action of the plate 14, the second vertical plate 12 and the second adjusting wheel 13 can move synchronously, thereby adjusting the vertical distance between the first adjusting wheel 1 and the second adjusting wheel 13, thus facilitating the adjustment of the tension of the kraft paper.
[0034] When the plate 14 moves up and down, it can drive the slide tube 10 to slide synchronously on the outer wall of the first vertical plate 2, thereby restricting the movement path of the plate 14. When the plate 14 moves up and down, it can drive the scale plate 3 to move synchronously in the inner cavity of the limiting tube 4. Under the scale markings of the scale plate 3, it is easy for the staff to keep track of the distance of the plate 14 moving up and down in real time.
[0035] Tighten the second bolt 21 to separate it from the second screw hole 19, then tighten the first bolt 16 to separate it from the first screw hole 18, then move the first vertical plate 2 upward to separate it from the mounting tube 20, and then move the plate 14 to separate the slide tube 10 from the first vertical plate 2, so as to facilitate the disassembly and replacement of the first adjusting wheel 1 and the second adjusting wheel 13.
