Fig. 2 described in the utility modelly compresses the view of cutter sweep when in running order be used to the tubing that cuts the pvc pipe material.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 1, shown in Figure 2, described be used to cutting the tubing compression cutter sweep of pvc pipe material, comprise: frame 1, in frame 1, along the traffic direction of tubing 2 interval expansion bearing successively, some support rollers 3 are arranged, the upper surface of all support rollers 3 forms the tubing holding plane jointly, frame 1 top between any two adjacent support rollers is equipped with the first guide pin bushing 4 and the second guide pin bushing 41, in the first guide pin bushing 4, be movably set with first guide pillar 5 that can move up and down along the first guide pin bushing 4, in the second guide pin bushing 41, be movably set with second guide pillar 51 that can move up and down along the second guide pin bushing 41, the upper end of the upper end of the first guide pillar 5 and the second guide pillar 51 all fixes with upper support frame 6, on upper support frame 6, vertically be provided with telescopic cylinder 7, on the piston rod of telescopic cylinder 7, be fixed with grip block 8, the lower end of the lower end of the first guide pillar 5 and the second guide pillar 51 all fixes with lower support frame 10, expansion bearing has diameter to be greater than the cutting blade 11 of tubing 2 bores in lower support frame 10, cutting blade 11 rotates under the driving of driving mechanism, in the present embodiment, the structure of described driving mechanism is: expansion bearing has connecting axle 12 in lower support frame 10, the two ends of connecting axle 12 are respectively installed with cutting blade 11 and driven pulley 13, in lower support frame 10, also be provided with drive motors 14, on the output shaft of drive motors 14, be provided with driving wheel 15, between driving wheel 15 and driven pulley 13, be provided with Timing Belt 16, drive motors 14 drives driven pulley 13 by driving wheel 15 and Timing Belt 16 and rotates, the synchronous cutting blade 11 that drives rotates, this driving mechanism structure is simple, installation and maintenance are convenient, when the piston rod of telescopic cylinder 7 stretches out, after the tubing 2 that grip block 8 is compressed downwards be positioned on the tubing holding plane, in telescopic cylinder 7 the remainder stroke amount of piston rod guarantee along with piston rod continue stretch out, can promote upper support frame 6 moves up, synchronous drive the first guide pillar 5 and the second guide pillar 51 move up along the first guide pin bushing 4 and the second guide pin bushing 41 respectively, the synchronous lower support frame 10 that drives moves up, and cutting blade 11 on lower support frame 10 is bottom-up until be positioned at cuts tubing 2.
