Detailed Implementation

[0020] Example 1, as Figure 1-5 As shown, a paper tube unloading and slitting machine includes a base plate 1. A control box 4 is fixedly installed on the surface of the base plate 1. The control box 4 contains a PLC controller (model: S7-200 SMART) and a drive motor (power: 2.2kW). The drive motor and the PLC controller are electrically connected. The output end of the drive motor is fixedly installed with a paper tube shaft 5 via a coupling. A collection box 6 is fixedly installed on the surface of the base plate 1.

[0021] Reference Figure 1-4As shown, in this embodiment: the pushing device 2 includes a long groove 21 formed on the surface of the base plate 1 and an L-shaped plate 22 that slides inside the groove 21. A pushing ring 23 is fixedly installed at the end of the L-shaped plate 22 away from the long groove 21. A groove 24 is formed on the side of the base plate 1 and a displacement plate 25 that slides inside the groove 24. The end of the displacement plate 25 away from the groove 24 is fixedly connected to the L-shaped plate 22. A first motor 26 is fixedly installed on the surface of the vertical end of the displacement plate 25. A gear 2 is fixedly installed at the output end of the first motor 26 through a coupling. 7. A rack 28 is fixedly installed on the surface of the base plate 1. The gear 27 and the rack 28 mesh with each other. The first motor 26 is electrically connected to the PLC controller inside the control box 4. The power of the first motor 26 is 0.75kW and the speed is 1400r / min. The gear 27 has a module of 2 and 20 teeth. The rack 28 has a module of 2 and a length of 500mm. The gap between the inner diameter of the push ring 23 and the outer diameter of the paper tube shaft 5 is 2-3mm. The length of the rack 28 is not less than 1.2 times the effective cutting length of the paper tube shaft 5. This allows the push ring 23 to push the cut paper tubes on the paper tube shaft 5 into the collection box 6, achieving the purpose of automatically unloading the cut paper tubes and improving the work efficiency of the staff.

[0022] Reference Figure 2-3 As shown in this embodiment: a groove 7 is provided on the surface of the base plate 1, and a hollow seat 8 and a vertical plate 11 that is slidably inserted inside the groove 7 are slidably connected. A second motor 12 is fixedly installed on the surface of the vertical plate 11. A rotating shaft 13 is fixedly installed on the output end of the second motor 12 through a coupling. Multiple cutting blades 14 are evenly distributed on the outer wall surface of the rotating shaft 13. The second motor 12 is electrically connected to the PLC controller inside the control box 4. A rectangular plate 9 is fixedly installed on the surface of the base plate 1, and an electric telescopic rod 10 is fixedly installed on the surface of the rectangular plate 9. The output end of the electric telescopic rod 10 is fixedly connected to the hollow seat 8. The electric telescopic rod 10 is electrically connected to the PLC controller inside the control box 4. The second motor 12 drives the rotating shaft 13 to rotate. The cutting blades 14 cut the paper tube. The electric telescopic rod 10 moves the hollow seat 8 inside the groove 7.

[0023] Reference Figure 3-5As shown in this embodiment: the surface of the hollow base 8 is provided with a limiting device 3 to limit the upright plate 11 inside the hollow base 8. The limiting device 3 includes a strip groove 31 formed on the surface of the hollow base 8 and two sliding blocks 32 inside it. A spring 33 is fixedly installed between the two sliding blocks 32. The limiting device 3 also includes a hinge plate 34 hinged to the surface of the end of the sliding block 32 away from the strip groove 31. A horizontal plate 35 is hinged to the end of the hinge plate 34 away from the sliding block 32. The limiting device 3 also includes an L-shaped bracket 36 fixedly installed on the surface of the upright plate 11 and a through hole 37 formed on its surface. A rod 38 is fixedly installed on the surface of the horizontal plate 35. The end of the rod 38 away from the horizontal plate 35 is inserted into the through hole 37. The rod 38 and the through hole 37 of the upright plate 11 are H7 / g6. With clearance fit, the spring 33 restricts the position of the slider 32 inside the strip groove 31, the hinge plate 34 drives the slider 32 to move inside the strip groove 31, and the insert rod 38 and through hole 37 limit the upright plate 11 inside the hollow seat 8.

[0024] Working principle: When the device is needed, first insert the paper tube into the paper tube shaft 5. Then, the PLC controller inside the P control box 4 controls the electric telescopic rod 10, the first motor 26, and the drive motor to start. The electric telescopic rod 10 drives the hollow seat 8 to move inside the slide groove 7. The movement of the hollow seat 8 inside the slide groove 7 drives the upright plate 11 to move. The movement of the upright plate 11 ultimately drives the cutting blade 14 to move. At the same time, the second motor 12 starts and drives the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 drives the cutting blade 14 to rotate, and the drive motor starts and drives the paper tube shaft 5 to rotate. The paper tube shaft 5 rotates, causing the paper tube to rotate. When the cutting blade 14 moves to a position that contacts the surface of the paper tube, the electric telescopic rod 10 is closed. Then, the rotating paper tube shaft 5 and the rotating cutting blade 14 complete the paper tube cutting operation. After cutting, the electric telescopic rod 10 is restarted, causing the electric telescopic rod 10 to drive the hollow seat 8 to reset inside the slide groove 7. Then, the PLC controller inside the control box 4 controls the first motor 26 to start. The first motor 26 drives the gear 27 to rotate. The gear 27 rotates and meshes with the rack 28, thereby causing the displacement plate 25 to move inside the groove 24. The movement of plate 25 inside groove 24 causes L-shaped plate 22 to move inside long groove 21. The movement of L-shaped plate 22 inside long groove 21 causes push ring 23 to move. Push ring 23 pushes the paper tubes cut from the surface of paper tube shaft 5 into the collection box 6 for collection. This achieves the purpose of automatic unloading of paper tubes after cutting, improving the work efficiency of the workers. When different cutting components need to be replaced according to actual needs, since the equidistant distance between each cutting blade 14 on the rotating shaft 13 of different cutting components is different, the horizontal plate 35 can be pressed first. The horizontal plate 35 moves and drives the hinge plate 34. The movement of the hinge plate 34 pushes the two sliders 32 to move away from each other inside the strip groove 31. The movement of the two sliders 32 away from each other inside the strip groove 31 will cause the spring 33 to stretch. At the same time, the movement of the horizontal plate 35 will also cause the insertion rod 38 to move. The movement of the insertion rod 38 will cause it to lose its limit inside the through hole 37. The separation of the insertion rod 38 and the through hole 37 will cause the vertical plate 11 to lose its limit inside the hollow seat 8. At this time, the vertical plate 11 can be removed from the hollow seat 8 and replaced with a new one. This allows the device to cut paper tubes of different sizes, further improving the adaptability of the device.
