A fixing frame 2 is fixed to the surface of the bottom plate 1 by bolts, and a cutting assembly is arranged on the fixing frame 2. A bearing seat 8 is fixed to the bottom plate 1 by bolts, and a V-shaped opening is provided on the bearing seat 8. The PTFE rod body 7 is arranged in the V-shaped opening, and the PTFE rod body 7 can move in the V-shaped opening. An inclined plate 11 is fixed to the bottom plate 1 by bolts for bearing the cutting part of the PTFE rod body 7. A sliding opening 12 is provided on the inclined plate 11, and a sliding block 22 is slidably connected in the sliding opening 12. A stopper 23 is fixed by bolts, and the stopper 23 contacts the end of the polyfluoro rod body 7, pushing the polyfluoro rod body 7 to move to the inclined plate 11 and contact the stopper 23. The movement of the polyfluoro rod body 7 pushes the stopper 23 to move. The movement of the stopper 23 causes the slider 22 to move along the slide 12. A controller 19 is provided on the inclined plate 11. The distance between the initial position of the stopper 23 and the controller 19 is the size of the polyfluoro rod body 7 required to be cut.

[0022] In the utility model, the cutting component is a cutting blade 6, an electric push rod 5 is fixed to the top of the fixed frame 2 by bolts, one end of the electric push rod 5 passes through the fixed frame 2 and is fixed to the connecting frame 4 by bolts, a motor 3 is fixed to one side of the connecting frame 4 by bolts, and the cutting blade 6 is fixedly connected to the circumferential outer wall of the output shaft of the motor 3. The controller 19 is mainly used to control the operation of the motor 3 and the electric push rod 5.

[0023] In the utility model, the control component includes a plug 21 and a socket 20. The plug 21 is fixedly connected to one side of the slider 22. The socket 20 is provided on one side of the controller 19. The plug 21 is plugged into the socket 20. A spring 13 is welded in the sliding mouth 12, and one end of the spring 13 is fixed to the slider 22. The block 23 moves to move the slider 22. When the plug 21 on the slider 22 is inserted into the socket 20 on the controller 19, the controller 19 is powered on and starts to control the electric push rod 5 and the motor 3 to work. When the plug 21 is disengaged from the socket 20, the controller 19 is powered off and stops running, and the electric push rod 5 and the motor 3 stop running.

[0024] In the utility model, the adjustment component is a screw 17, and the side wall of the inclined plate 11 is slidably connected with a slide 18, one end of the slide 18 is fixed to the controller 19, and the side wall of the inclined plate 11 is rotatably connected with the screw 17, and the screw 17 passes through the slide 18 and is threadedly connected with the slide 18. The side of the inclined plate 11 is provided with a scale line 16, and the slide 18 corresponds to the scale line 16. When it is necessary to adjust the cutting size, the screw 17 is rotated, and the rotation of the screw 17 causes the slide 18 to drive the controller 19 to move, thereby adjusting the distance between the jack 20 and the plug 21, adjusting the distance between the initial state slider 22 and the controller 19, and controlling the working time difference of the controller 19. The value of the distance moved by the slide 18 can be observed through the value corresponding to the scale line 16 and the slide 18.

[0025] In the utility model, a connecting frame 15 is fixed to one side of the connecting frame 4 by bolts, a rubber baffle 14 is fixed to the bottom of the connecting frame 15 by bolts, and the rubber baffle 14 can fit with the side of the polytetrafluoroethylene rod body 7, a reserved opening 10 is opened on the inclined plate 11, and the rubber baffle 14 can extend into the reserved opening 10, and a material blocking frame 9 is fixed to one side of the inclined plate 11 by bolts, and the connecting frame 15 drives the rubber baffle 14 to move downward during the downward movement of the connecting frame 4, and the rubber baffle 14 moves downward and fits with the outer wall of the polytetrafluoroethylene rod body 7, thereby blocking the polytetrafluoroethylene rod body 7 to prevent the polytetrafluoroethylene rod body 7 from shaking when the cutting is about to be completed, and the rubber baffle 14 can enter the reserved opening 10 when it continues to move downward, and the cut polytetrafluoroethylene rod body 7 can roll from the inclined plate 11 to the material blocking frame 9.

[0026] Working principle: when it is necessary to cut the PTFE rod body 7, the PTFE rod body 7 is placed in the V-shaped opening on the bearing seat 8, and the PTFE rod body 7 is pushed to move to the inclined plate 11 and contact the stopper 23, and the PTFE rod body 7 is continuously pushed to move. At this time, the movement of the PTFE rod body 7 pushes the stopper 23 to move, and the movement of the stopper 23 causes the slider 22 to move along the sliding opening 12, and the spring 13 contracts under force. When the plug 21 on the slider 22 is inserted into the socket 20 on the controller 19, the controller 19 is powered on and starts to operate to control the electric push rod 5 and the motor 3 to work. At this time, the PTFE rod body 7 is stopped from being pushed, and the electric push rod 5 is extended to make the connecting frame 4 move downward as a whole, and the cutting blade 6 moves downward to contact the PTFE rod body 7. The motor 3 works to make the cutting blade 6 rotate, and the cutting blade 6 rotates to perform a cutting operation on the PTFE rod body 7;

[0027] When the connecting frame 4 moves downward, the connecting frame 15 drives the rubber baffle 14 to move downward, and the rubber baffle 14 moves downward to fit the outer wall of the polytetrafluoroethylene rod body 7, thereby blocking the polytetrafluoroethylene rod body 7 to prevent the polytetrafluoroethylene rod body 7 from shaking when the cutting is about to be completed. When the rubber baffle 14 continues to move downward, it can enter the reserved opening 10;

[0028] After the cutting is completed, the electric push rod 5 retracts to make the connecting frame 4 move upward, and the rubber baffle 14 moves upward to disengage from the cut PTFE rod body 7. At this time, the PTFE rod body 7 can roll down from the inclined plate 11 to the material blocking frame 9. After the cut PTFE rod body 7 is separated from the stopper 23, the spring 13 rebounds and resets to make the slider 22 drive the stopper 23 to reset along the sliding mouth 12. The slider 22 resets to make the plug 21 disengage from the socket 20. At this time, the controller 19 is powered off and stops running, so that the electric push rod 5 and the motor 3 stop running, and a cutting operation is realized. Repeating the above operation can push the PTFE rod body 7 to complete the next stage of cutting work.

[0029] When the cutting size needs to be adjusted, the screw 17 is rotated, and the rotation of the screw 17 causes the slide 18 to drive the controller 19 to move, thereby adjusting the distance between the jack 20 and the plug 21, and the value of the scale line 16 corresponding to the slide 18 can control the distance value of the slide 18 movement.
