Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] like Figure 1-Figure 7As shown, a cutting device for fire protection pipe production includes: a processing cabinet 1, two symmetrically arranged fixed plates 11 are fixedly connected to the top of the processing cabinet 1, linear guide rails 12 are fixedly installed on opposite sides of the two fixed plates 11, and a cutting machine body 13 is fixedly installed on the linear guide rails 12, and material receiving platforms 14 are provided on opposite sides of the two fixed plates 11; a blanking component, the blanking component is arranged on the two material receiving platforms 14, and is used to unload the pipes from the two material receiving platforms 14, and a lifting component is arranged on the processing cabinet 1, and is used to adjust the height of the material receiving platform 14.

[0028] During use, the cutting machine body 13 is driven to move by the linear guide rail 12, and then the cutting machine body 13 is started to cut the fire pipe. The cut pipe falls on the receiving platform 14. Each time a section of the pipe is cut, the cut pipe is transported downward through the unloading component. Secondly, the receiving platform 14 can be adjusted by the lifting component so that one end of the pipe of different diameters can be supported to avoid the pipe breaking due to gravity, resulting in an uneven incision of the pipe and poor cutting quality.

[0029] Example 2

[0030] On the basis of Example 1, the unloading assembly includes: a groove 2, a roller 21, a protrusion 22, a transmission rod 23, a reducer 24 and a unloading trough 25. Grooves 2 are respectively provided on opposite sides of the two receiving platforms 14. The two grooves 2 are respectively rotatably connected to the rollers 21 on opposite sides. The two rollers 21 are fixedly connected to the outside with two symmetrically arranged protrusions 22. A transmission rod 23 is fixedly connected between the two rollers 21 located on the same horizontal line. The two receiving platforms 14 are respectively fixedly installed with reducers 24. One end of the drive shaft of the two reducers 24 is respectively connected to the axis of the adjacent rollers 21. A unloading trough 25 is provided at the top of the processing cabinet 1 near the fixed plate 11. The two lifting platforms 31 are respectively threaded with screws b26, and one end of the screw b26 is rotatably connected to one side of the receiving platform 14. The two lifting platforms 31 are respectively slidably connected with guide rods 27, and one end of the two guide rods 27 is fixedly connected to one side of the receiving platform 14.

[0031] The cut pipe falls onto the two rollers 21, and then the two reducers 24 are started. The two reducers 24 rotate relative to each other, and the reducers 24 drive the two rollers 21 to rotate relative to each other, and the transmission rods 23 drive the two rollers 21 to rotate relative to each other, and then the rollers 21 drive the protrusions 22 to rotate, and the two protrusions 22 move away from the lower surface of the pipe, so that the pipe loses its restriction and falls downward into the discharge chute 25, thereby unloading the cut pipe. After the reducer 24 is started, it only drives the two rollers 21 to rotate 180 degrees and then stops working, so that the two When the roller 21 rotates 90°, the protrusion 22 is perpendicular to the ground, and the pipe loses its restraint and falls downward. After rotating 180°, the two protrusions 22 exchange positions, and the protrusions 22 support the pipe in parallel. The distance between the two receiving platforms 14 is adjusted according to the diameter of the cut pipe, and then the screw b26 is rotated to engage with the lifting platform 31. Due to the restriction of the two guide rods 27, the two receiving platforms 14 will be driven to move when the threads are engaged. The relative or back-to-back movement of the two receiving platforms 14 can be controlled by controlling the rotation direction of the two screws b26.

[0032] Example 3

[0033] On the basis of Example 1, the lifting assembly includes: a moving groove 3, a lifting platform 31, a moving hole 32, a mounting cavity 33, a screw a34 and a turbine 35. The two fixed plates 11 are respectively provided with a moving groove 3 on the opposite side, and the two moving grooves 3 are respectively provided with a lifting platform 31. The processing cabinet 1 has two moving holes 32 inside, and the two moving holes 32 are respectively provided with a mounting cavity 33 around them. The two moving holes 32 are both provided with a screw a34. The top of the screw a34 is connected to the bottom of the lifting platform 31, and the external thread of the screw a34 is connected to the turbine 35. The turbine 35 is located inside the mounting cavity 33. A worm 36 is provided, which is meshed with the turbine 35. A servo motor 37 is fixedly installed inside the mounting cavity 33. One end of the drive shaft of the servo motor 37 is connected to one end of the worm 36. Two symmetrically arranged limit blocks 38 are fixedly connected to the inner wall of the movable hole 32 near the top. Two symmetrically arranged guide grooves 39 are provided on the outside of the screw a34. The two limit blocks 38 are respectively located inside the two guide grooves 39. A slide groove 310 is respectively provided on the opposite side of the two movable grooves 3. A slider 311 is respectively provided on the opposite side of the lifting platform 31. The two sliders 311 are respectively located inside the two slide grooves 310.

[0034] When the height of the lifting platform 31 needs to be adjusted, the two servo motors 37 are started to drive the two worms 36 to rotate, the worm 36 rotates to engage with the turbine 35, and the turbine 35 rotates to engage with the screw a34. Since the screw a34 is restricted by the limit block 38 and the guide groove 39, the screw a34 can only move along the vertical direction of the limit block 38. The movement of the screw a34 can drive the lifting platform 31 to move. When the lifting platform 31 moves, it drives the slider 311 to move along the inside of the two slide grooves 310. The height of the lifting platform 31 is controlled by controlling the rotation direction of the two servo motors 37 to adjust the height of the lifting platform 31, so that the two rollers 21 can support the bottom of the pipeline.
