The PE pipe edge cutting device comprises: a base 1, on which a fixing mechanism and a stabilizing mechanism are arranged;

[0024] The fixing mechanism comprises a driving motor 2, which is fixedly mounted on a base 1, an output end of the driving motor 2 is fixedly connected with a bevel gear 3, one side of the bevel gear 3 is meshingly connected with a driven gear 4, a rotating tube 5 is fixedly connected to the driven gear 4, one end of the rotating tube 5 is fixedly connected with a connecting tube 6, the other end of the connecting tube 6 is fixedly connected with a fixing tube 7, an arc-shaped clamping block 8 is slidably connected to the fixing tube 7, an air bag 9 is arranged inside the fixing tube 7, one side of the air bag 9 is fixedly connected with a connecting air pipe 10, the other end of the connecting air pipe 10 is fixedly connected with a sealing bearing 11, the inner side of the sealing bearing 11 is fixedly connected with an air inlet pipe 12, the outer wall of the rotating tube 5 is rotatably connected with a fixing platform 13, and the fixing platform 13 is fixedly connected to the base 1;

[0025] A mounting plate 21 is fixedly connected to the base 1 , a cutter head 22 is disposed on one side of the mounting plate 21 , two screws 23 are disposed on both the mounting plate 21 and the cutter head 22 , and the cutter head 22 is threadedly connected to the mounting plate 21 via the two screws 23 .

[0026] like Figure 1 As shown, the stabilizing mechanism includes a bottom plate 15, the bottom plate 15 is placed on the base 1, the top surface of the bottom plate 15 is rotatably connected to an inner corrugated tube 16, the inner corrugated tube 16 is internally threadedly connected to a threaded column 17, one side of the threaded column 17 is fixedly connected to a telescopic rod 18, the bottom end of the telescopic rod 18 is fixedly connected to the bottom plate 15, the top surface of the threaded column 17 is fixedly connected to a bearing plate 19, and two rollers 20 are rotatably connected to the bearing plate 19;

[0027] By setting the stabilizing mechanism, the other end of the PE pipe body 14 can be supported when the PE pipe body 14 is clamped and fixed, so that the curling and cutting work of the PE pipe body 14 can be carried out smoothly.

[0028] like Figure 1 As shown, the number of the arc-shaped blocks 8 is three, and the arc-shaped blocks 8 are distributed in a circular shape with equal distances about the transverse axis of the fixed tube 7, and the fixed tube 7 is provided with three slide grooves corresponding to the three arc-shaped blocks 8;

[0029] By providing the three arc-shaped clamping blocks 8, the contact area between the fixing mechanism and the PE pipe body 14 can be increased, thereby enhancing the fixing effect.

[0030] like Figure 1 As shown, the top of the arc-shaped block 8 is made of rubber material, and the bottom size of the arc-shaped block 8 matches the inner wall size of the fixed tube 7 .

[0031] By matching the bottom size of the arc-shaped clamping block 8 with the inner wall size of the fixing tube 7, the arc-shaped clamping block 8 can fit tightly with the inner wall of the fixing tube 7 after the airbag 9 is inflated, preventing the arc-shaped clamping block 8 from loosening and affecting the fixing effect on the PE pipe body 14.

[0032] like Figure 1 As shown, the air inlet pipe 12 is located on the transverse axis of the rotating pipe 5, and the transverse axes of the fixed pipe 7, the air bag 9, the connecting air pipe 10 and the PE pipe body 14 coincide with each other;

[0033] By arranging the horizontal axes of the fixed tube 7, the air bag 9, the connecting air pipe 10 and the PE pipe body 14 to coincide with each other, the device will not rotate eccentrically when the PE pipe body 14 is rotated.

[0034] like Figure 1As shown, the outer diameter of the threaded column 17 is the same as the inner diameter of the inner corrugated tube 16, and the threaded column 17 is located on the vertical axis of the bearing plate 19;

[0035] By arranging the threaded column 17 on the vertical axis of the bearing plate 19 , the stability of the stabilizing mechanism itself can be enhanced.

[0036] The working principle of the PE pipe edge cutting device provided by the utility model is as follows:

[0037] Step 1: When in use, first place the device in a suitable position, then put the PE pipe body 14 on the fixing pipe 7, press one side of the curled edge of the PE pipe body 14 to contact the cutter head 22, and at the same time move the stabilizing mechanism to the bottom of the other end of the PE pipe body 14 to allow the PE pipe body 14 to be initially stabilized, and then air is introduced from the air inlet pipe 12 to fill and expand the airbag 9, and then the arc-shaped block 8 is pushed out. After the arc-shaped block 8 is fixed to the PE pipe body 14, stop the air intake to the airbag 9 to maintain the fixed state;

[0038] Step 2: After the PE pipe body 14 is fixed, the inner corrugated tube 16 is rotated to push out the threaded column 17, and then the roller 20 is raised until the roller 20 contacts the outer wall of the PE pipe body 14. When the PE pipe body 14 of the same diameter is subsequently crimped and cut, the stabilizing mechanism can maintain the existing height, so that the PE pipe body 14 of different lengths can be adapted by moving the stabilizing mechanism;

[0039] The third step: start the driving motor 2 to drive the bevel gear 3 and the driven gear 4 to rotate, and then the driven gear 4 drives the connecting pipe 6, the fixed pipe 7 and the PE pipe body 14 to rotate, and the cutter head 22 cuts off the curling edge on the PE pipe body 14.
