Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4, in the embodiment of the present utility model, an automatic cutting device for paper tube production includes a fixing plate 1. A chute 17 is opened at the top of the fixing plate 1. Two guide rails 2 are fixedly connected to the top end of the fixing plate 1. A slider 3 is slidably connected to the inner sides of the two guide rails 2. The housing of a cylinder 4 is fixedly connected between the two sliders 3. The output shaft of the cylinder 4 is slidably connected to the inner side of the chute 17, and the bottom end of the output shaft of the cylinder 4 penetrates below the fixing plate 1. An upper mounting plate 5 is installed at the output end of the chute 17. A lower mounting plate 6 is installed on the upper mounting plate 5 through bolts. A rotating cutting mechanism for cutting the paper tube is installed on the lower mounting plate 6. A guiding mechanism is installed at the back end of the fixing plate 1 through a connecting mechanism; the guiding mechanism includes a connecting plate 15 detachably connected to the fixing plate 1 through a connecting mechanism. A first guiding groove 20 is opened at the middle position of the vertical plate part of the connecting plate 15. Two second guiding grooves 21 are opened on both sides of the vertical plate part of the connecting plate 15 at the first guiding groove 20. A third guiding groove 22 is opened on the outer sides of the two second guiding grooves 21 on the vertical plate part of the connecting plate 15. The lower half parts of the second guiding groove 21 and the third guiding groove 22 are in a vertical groove structure. The inclination degree of the upper half part of the third guiding groove 22 is greater than that of the upper half part of the second guiding groove 21. A sliding shaft 16 is movably connected to the inner walls of the first guiding groove 20, the second guiding groove 21, and the third guiding groove 22. The sliding shaft 16 is fixedly connected to the upper mounting plate 5.

[0020] In this embodiment: First, replace the corresponding guiding mechanism according to the required cutting length. After replacement, at this time, by starting the cylinder 4, the output end of the cylinder 4 drives the lower mounting plate 6 to move downward through the upper mounting plate 5. The lower mounting plate 6 drives the sliding shaft 16 to move simultaneously. Multiple sliding shafts 16 respectively move downward along the first guiding groove 20, the second guiding groove 21, and the third guiding groove 22. At this time, the sliding shafts 16 movably connected to the second guiding groove 21 and the third guiding groove 22 slide along the inclined grooves in their upper half parts. Therefore, the sliding shaft 16 drives the cylinder 4 to move axially through the lower mounting plate 6 and the upper mounting plate 5. The output shaft of the cylinder 4 slides along the chute 17. At the same time, the cylinder 4 drives the slider 3 to slide axially along the guide rail 2 until the sliding shaft 16 moves into the vertical grooves in the lower half parts of the first guiding groove 20, the second guiding groove 21, and the third guiding groove 22. During this process, the axially moving cylinder 4 drives the rotating cutting mechanism to move axially, so as to change the distance between adjacent rotating cutting mechanisms. Therefore, equidistant cutting of the paper tube can be achieved;

[0021] When cutting paper tubes of different specifications, replace the guiding mechanism through the connecting mechanism.

[0022] Please refer specifically to Figure 3 and Figure 4, the connecting mechanism includes a C-shaped frame 24 fixedly connected to the edge position of the top of the fixing plate 1. Inside the two vertical plate parts of the C-shaped frame 24, there are fixedly connected limiting bumps 30 fixedly connected to the top of the fixing plate 1. A plug rod 28 is slidably connected up and down on the cross plate part of the C-shaped frame 24. The top of the plug rod 28 is fixedly connected with a lifting handle 25. Between the top end of the lifting handle 25 and the cross plate part of the C-shaped frame 24, there is fixedly connected a connecting spring 27. The connecting spring 27 is sleeved on the plug rod 28. The bottom end of the plug rod 28 is formed with a pressure-receiving inclined surface. The connecting mechanism also includes a pressing inclined surface 26 integrally formed at one end of the cross plate part of the connecting plate 15. Inside the cross plate part of the connecting plate 15, there is a slot 29 sleeved with the plug rod 28. On both sides of the cross plate part of the connecting plate 15, there are openings 23 inserted with the limiting bumps 30.

[0023] In this embodiment: When replacing the guiding mechanism, by lifting the lifting handle 25 by hand, the lifting handle 25 drives the plug rod 28 to move upward until the plug rod 28 is completely separated from the slot 29. Then, the connecting plate 15 can be pulled to slide, and the replacement of the connecting plate 15 can be realized. Then, take another matching connecting plate 15. The connecting plate 15 drives the opening 23 to be aligned with the inner side of the limiting bump 30. Then, push the connecting plate 15 to move. The moving connecting plate 15 drives the pressing inclined surface 26 to move until the pressing inclined surface 26 contacts and presses against the pressure-receiving inclined surface at the bottom end of the plug rod 28. At this time, the plug rod 28 moves upward, and at this time, the connecting spring 27 is stretched until the plug rod 28 is aligned with the slot 29. At this time, the connecting spring 27 resets and drives the plug rod 28 to insert into the slot 29, and the fixing of the connecting plate 15 can be completed.

[0024] Please refer specifically to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the rotary cutting mechanism includes a rotary shaft 12 rotatably connected to one end inside the lower mounting plate 6. One end of the rotary shaft 12 is fixedly connected with a small transmission wheel 11. The other end of the rotary shaft 12 is detachably connected with a cutting blade 13 through a stud and a nut. The other end inside the lower mounting plate 6 is movably installed with a rotating shaft 8. An outer wall of the rotating shaft 8 is interference-fitted with a large transmission wheel 9. The large transmission wheel 9 and the small transmission wheel 11 are connected by a transmission belt 10 for transmission. The rotary cutting mechanism also includes a rotary motor 7 installed below the fixing plate 1. The output end of the rotary motor 7 is fixedly connected with one end of the rotating shaft 8. The rotary motor 7 and the fixing plate 1 are connected to the fixing plate 1 through a lifting mechanism and are slidable up and down.

[0025] In this embodiment: When cutting the paper tube, by starting the rotary motor 7, the rotary motor 7 drives the rotary shaft 8 to rotate. The rotary shaft 8 drives a plurality of large transmission wheels 9 that are interference-fitted on its outer wall to rotate synchronously. The large transmission wheels 9 drive the small transmission wheels 11 to rotate through the transmission belt 10. The rotating small transmission wheels 11 drive the cutting blade 13 to rotate through the rotating shaft 12, and thus the paper tube can be cut.

[0026] Please refer specifically to Figure 1 and Figure 2 , a fixing frame 14 is fixedly connected to the output end plate of the rotary motor 7. The top of the fixing frame 14 is fixedly connected to a lifting shaft 18 that is slidably connected to the fixing plate 1 up and down. A return spring 19 is fixedly connected between the bottom end of the protruding part at the top of the lifting shaft 18 and the top end of the fixing plate 1.

[0027] In this embodiment: When the cylinder 4 is operating, at this time the lower mounting plate 6 drives the fixing frame 14 to move up and down through the rotary shaft 8. The moving fixing frame 14 can drive the lifting shaft 18 to move up and down, and the lifting shaft 18 moves to compress or reset the return spring 19;

[0028] It should be noted that: During the operation of the cylinder 4, the rotary shaft 8 only moves up and down. Therefore, a sleeve is movably connected to the inner side of the lower mounting plate 6, and the inner circumference of the sleeve fits with the outer wall of the rotary shaft 8. Therefore, when the lower mounting plate 6 slides left and right, rotation and movement will occur between the outer circumference of the lower mounting plate 6 and the sleeve.

[0029] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
