In order to achieve the purpose of automatic power off after the pipe is cut off, when the electric serrated knife 16 contacts the pressure sensor of the lower limit plate 10 in the processing box 1, when the pressure sensor 17 provided in conjunction with the same contacts, the PLC controller cuts off the power supply of the motor 11 and the electric serrated knife 16. On the contrary, when the electric serrated knife 16 contacts the pressure sensor of the upper limit plate 10 in the processing box 1, the PLC controller still cuts off the power supply of the motor 11 and the electric serrated knife 16. Secondly, in order to facilitate the starting of the motor 11 and the electric serrated knife 16, the device is also provided with a matching control switch corresponding to the motor 11 and the electric serrated knife 16. The installation position of the control switch is selected according to the actual use requirements, so as to facilitate the operator to perform operation and control.

[0022] In one embodiment, positioning rings 5 ​​are welded on both sides of the processing box 1 corresponding to the through holes 2, and a clearance opening is opened on the surface of the positioning ring 5 corresponding to the clamp 4. The positioning ring 5 is arranged to provide a guide and support structure for the glass fiber braided pultruded tube to be cut, so that the glass fiber braided pultruded tube is easily cut, and the clearance opening is used to make way for the clamp 4.

[0023] In one embodiment, a bearing seat is provided at one end of the screw 12 away from the motor 11, and the bearing seat is connected to the uppermost limit plate 10 in the processing box 1. Through the setting of the bearing seat, reliable support is provided for the screw 12 while satisfying its rotation.

[0024] In one embodiment, a T-shaped slide groove is provided on one side of the slide 13 away from the electric serrated knife 16, and the T-shaped slide bar 15 is slidably connected to the T-shaped slide groove.

[0026] In one embodiment, supports 6 are welded on both the left and right sides of the bottom of the processing box 1, and the supports 6 are in the shape of a right-angled triangle frame as a whole. The support 6 is provided to maintain the supporting effect of the processing box 1.

[0027] Working principle:

[0028] When in use, first insert the glass fiber braided pultruded tube to be cut into the through hole 2 of the processing box 1. When the part of the glass fiber braided pultruded tube to be cut reaches the cutting station of the electric sawtooth knife 16, the cylinder 3 fixed on the outer periphery of the through hole 2 is started to extend, so that the clamp 4 fixed on the cylinder 3 with the arc surface set on its end face is against the outer wall of the glass fiber braided pultruded tube to clamp the glass fiber braided pultruded tube. When cutting, the motor 11 in the processing box 1 is started to drive the motor 11 to drive the screw 12 fixed at its output end to rotate, and then the threaded sleeve 14 built into the slide seat 13 moves along the surface of the screw 12 to drive the electric sawtooth knife 16 to move synchronously, and the T-shaped slide bar 15 is slidably connected to the slide seat 13. The electric serrated knife 16 maintains the smooth movement of the electric serrated knife 16, so that the electric serrated knife 16 after startup cuts the glass fiber braided pultruded tube clamped in the through hole 2, and the cutting debris falls into the collecting box 7 at the bottom of the processing box 1. When the electric serrated knife 16 contacts the pressure sensor of the lowermost limit plate 10 in the processing box 1 and the matching pressure sensor 17, the PLC controller cuts off the power supply of the motor 11 and the electric serrated knife 16. When it is necessary to clean the cutting debris, the collecting box 7 is pulled so that the L-shaped guide frame 9 of the collecting box 7 and the guide strip 8 at the bottom of the processing box 1 slide relative to each other until the collecting box 7 is completely separated from the processing box 1, and the debris can be cleaned.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
