[0033] The working principle of the PVC pipe cutting device is as follows:
[0034] Clamping process:
[0035] Firstly, the PVC pipe to be cut is placed on the top of the support table 1 and located on the inner wall of the two ring bodies 14 of the clamping structure, the position of the PVC pipe is adjusted, the one end of the PVC pipe is ensured to be in contact with the horizontal electric push rod 2, the worker adjusts the initial position of the horizontal electric push rod 2 through the controller 24, so that the one end of the PVC pipe close to the cutter 6 is located in the same vertical plane with the cutter 6, this step ensures that the pipe can be accurately positioned on the path of the cutter 6 during cutting, then the horizontal electric push rod 2 is started, the horizontal electric push rod 2 pushes the PVC pipe out of a proper distance, the distance is determined according to the preset cutting length, so as to ensure that the length of the pipe after cutting meets the requirements, after the pipe is pushed into place, the second motor 8 is started, the output end of the second motor 8 drives the first worm 9 to start rotating, since the first worm 9 is meshed and connected with the two first worm gears 11 respectively, the rotation of the first worm 9 drives the two first worm gears 11 to rotate synchronously, the rotation of the first worm gear 11 further drives the second worm 10 fixedly connected therewith to rotate, the rotation of the second worm 10 drives the second worm gear 13 inside the housing 12 to rotate, in the process of rotation, the sliding groove 16 formed in the second worm gear 13 extrudes a plurality of sliding rods 15, after being extruded, the sliding rod 15 moves along the track of the sliding groove 16 and simultaneously compresses the spring 17, with the movement of the sliding rod 15, the clamping block 18 also gradually approaches the axis of the ring body 14. The clamping block 18 continuously clamps the PVC pipe during movement, until the pipe is clamped stably, the arc-shaped design and the round corner treatment of the clamping block 18 ensure that the pipe is not damaged during the clamping process;
[0036] Cutting process:
[0037] After the pipe is firmly clamped, the cutting process starts, first, the longitudinal electric push rod 4 is started by the controller 24, the output end of the longitudinal electric push rod 4 drives the knife holder 5 to slowly descend along the support frame 3, in the descending process, the cutter 6 inside the knife holder 5 gradually approaches the pipe, until the pipe is contacted and starts to cut, at the same time, the first motor 7 is started, the output end of the first motor 7 drives the cutter 6 to rotate at high speed, so as to produce the cutting effect, the rotating cutter 6 can quickly and accurately cut the pipe, at the same time, the friction and heat generation in the cutting process are reduced, the debris generated in the cutting process will be effectively blocked by the debris blocking structure, the arc-shaped groove 20 inside the debris blocking plate 19 can guide the debris to move to the direction of the collecting groove 21, so as to prevent the debris from splashing to the working area or hurting the operator, the collecting groove 21 is located below the cutter 6, and the bottom thereof is inclined, so that the debris can smoothly slide into the collecting box 23 along the inclined surface, after the cutting is completed, the longitudinal electric push rod 4 drives the knife holder 5 to rise and return to the initial position, at this time, the transverse electric push rod 2 can be started to push the cut pipe out, so as to prepare for the next cutting, when the debris in the collecting box 23 is more, the collecting box 23 can be taken out, and the debris therein is cleaned, so as to carry out the subsequent cutting operation.
