Specific embodiments

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] Referring to Figures 1-5 as shown, an adjusting handwheel for a single-stem straw packaging machine includes a main board 1. A first sliding groove 2 is opened inside the main board 1. Two sliding rods 3 are fixedly installed on the inner wall of the first sliding groove 2. The two sliding rods 3 are symmetrically distributed about the center line of the first sliding groove 2. A double-headed screw 4 is rotatably installed at the center of the inner wall of the first sliding groove 2. Two sliders 5 are arranged inside the first sliding groove 2. The sliders 5 are threadedly connected to the double-headed screw 4 and are slidably connected to the two sliding rods 3. The double-headed screw 4 controls the two sliders 5 to separate from and approach each other. The sliding rods 3 ensure that the sliders 5 are more stable during the movement. A support rod 6 is fixedly installed on the upper surface of the slider 5. An unlocking assembly 7 is fixedly installed inside the upper end of the support rod 6. A connecting gear 20 is arranged inside the unlocking assembly 7. A sleeve 8 is sleeved on the outer surface of the support rod 6. The connecting gear 20 is slidably connected to the sleeve 8. The connecting gear 20 prevents the sleeve 8 from rotating during the material transportation. A locking assembly 9 is fixedly installed on the inner wall of the sleeve 8 corresponding to the unlocking assembly 7. The locking assembly 9 cooperates with the unlocking assembly 7 to achieve the quick installation and disassembly of the sleeve 8, greatly reducing the steps required for the staff to maintain or produce straws of different models. A roller 10 is rotatably installed on the outer surface of the sleeve 8.

[0023] As shown Figure 4 in the figure, the unlocking component 7 includes a first main body 11. A first moving groove 12 is formed inside the first main body 11. Through grooves 13 are formed through both sides of the inner wall of the first moving groove 12. Two connecting rods 14 are arranged inside the through grooves 13. The connecting rods 14 are slidably connected to the first main body 11 through the through grooves 13. Second sliding grooves are formed on the inner walls of the through grooves 13. First baffles corresponding to the second sliding grooves are fixedly installed on the outer surfaces of the connecting rods 14. A first spring 15 is sleeved on the outer surfaces of the connecting rods 14. Two ends of the first spring 15 are respectively fixedly connected to one side of the first baffle away from the first moving groove 12 and the inner wall of the second sliding groove. The first spring 15 pushes the first baffle on the connecting rod 14 so that the connecting rod 14 can quickly reset after moving, and at the same time, the first baffle limits the connecting rod 14.

[0024] As shown Figure 4 in the figure, a fixing rod 16 is arranged inside the first moving groove 12. A cam 17 and a second baffle 18 are fixedly installed on the outer surface of the fixing rod 16. The connecting rod 14 is located between the cam 17 and the second baffle 18, and the connecting rod 14 abuts against the second baffle 18. A second spring 19 is sleeved on the outer surface of the fixing rod 16 corresponding to the lower part of the second baffle 18. Two ends of the second spring 19 are respectively fixedly connected to the lower surface of the second baffle 18 and the bottom of the inner wall of the first moving groove 12. After the fixing rod 16 moves, the second spring 19 pushes the fixing rod 16 on the second baffle 18 to quickly reset. A connecting gear 20 is fixedly installed at the upper end of the fixing rod 16. A fixing groove 21 is formed on the upper surface of the first main body 11 corresponding to the connecting gear 20. When a staff member squeezes the connecting gear 20, the connecting gear 20 pushes the cam 17 on the fixing rod 16 to move downward, and the cam 17 pushes the connecting rod 14 to unlock the locking component 9.

[0025] As shown Figure 5 in the figure, the locking component 9 includes a second main body 22. A second moving groove 23 is formed on the inner wall of the second main body 22. A guide rod 24 is fixedly installed on the inner wall of the second moving groove 23. A moving plate 25 is arranged inside the second moving groove 23. An insertion rod 26 corresponding to the connecting rod 14 is fixedly installed on one side of the moving plate 25 away from the guide rod 24. A slope is arranged on the lower surface of the insertion rod 26, and the slope facilitates the first main body 11 to push the insertion rod 26. A third spring 27 is sleeved on the outer surface of the guide rod 24. Two ends of the third spring 27 are respectively fixedly connected to one side of the moving plate 25 away from the insertion rod 26 and the inner wall of the second moving groove 23. The third spring 27 constantly pushes the moving plate 25 to abut against the second moving groove 23. When installing the installation sleeve 8, the first main body 11 pushes the insertion rod 26 so that the insertion rod 26 constantly abuts against the surface of the first main body 11. When the insertion rod 26 moves to the through groove 13, the third spring 27 pushes the insertion rod 26 to quickly enter the through groove 13.

[0026] As shownFigures 1-2 As shown in the figure, a circular plate 28 is provided on the outer side of the main board 1 corresponding to the double-headed screw 4. The double-headed screw 4 passes through the main board 1 and is fixedly connected to the circular plate 28. A handle 29 is rotatably installed on the side of the circular plate 28 away from the double-headed screw 4. The staff can control the forward and reverse rotation of the double-headed screw 4 by pushing the handle 29 to rotate the circular plate 28.

[0027] As Figures 1-5 shown in the figure, a groove 30 is provided on the outer surface of the roller 10, and the groove 30 facilitates the movement of the material.

[0028] As Figures 1-2 shown in the figure, hanging ears 31 are fixedly installed on both the left and right sides of the main board 1 corresponding to the double-headed screw 4. The staff can fix the hanging ears 31 on the equipment through bolts.

[0029] Staff: During equipment maintenance, the staff presses the connecting gear 20. The connecting gear 20 pushes the cam 17 on the fixing rod 16 to move downward, so that the cam 17 pushes the connecting rod 14 to move. The connecting rod 14 pushes the insertion rod out of the through groove 13, and then the sleeve 8 is removed. After removal, the third spring 27 pushes the fixing rod 16 on the second baffle 18 to reset, and at the same time the first spring 15 pushes the connecting rod 14 to quickly reset, so that the connecting rod 14 contacts the baffle, thereby completing the limit of the fixing rod 16. The third spring 27 pushes the insertion rod 26 on the moving plate 25 to quickly reset; during installation, the first main body 11 pushes the insertion rod 26 to move. The third spring 27 enables the insertion rod 26 to be in contact with the surface of the first main body 11 in real time. When the insertion rod 26 moves to the through groove 13, the third spring 27 can push the insertion rod 26 to quickly enter the through groove 13, so that the sleeve 8 is quickly installed on the support rod 6.
