Technical Field
[0001] This utility model relates to the field of pipe breakers, specifically a PE pipe breaker. Background Technology
[0002] PE pipes are pipes made primarily of polyethylene and have a wide range of applications, from small-section yellow pipes for natural gas to thick-walled black pipes for industrial and urban pipelines. A PE pipe cutter is a tool specifically designed for cutting PE pipes and is widely used in gas pipeline laying, maintenance, and emergency repair work to ensure that PE pipes can be cut quickly.
[0003] Existing PE pipe cutters typically involve manually tightening the threaded rod to lower the cutting blade and cut the PE pipe. However, since some PE pipes are thick and are usually cut straight, the amount of physical effort required during the cutting process is considerable. Therefore, a new PE pipe cutter is proposed to address these issues. Utility Model Content

[0027] In the embodiments, by Figure 1-4 This invention discloses a PE pipe cutter, comprising a pipe cutter frame 1, a rotating threaded sleeve 2 rotatably connected to the inner side of the pipe cutter frame 1, a rotating threaded rod 3 connected to the inner side of the rotating threaded sleeve 2 via threaded transmission, a power component 4 fixedly connected to the outer side of the rotating threaded sleeve 2, a movable frame 5 fixedly connected to the bottom end of the rotating threaded rod 3, a limit component 6 fixedly connected to the outer side of the movable frame 5, a connecting plate 7 fixedly connected to the inner side of the movable frame 5, a telescopic movable component 8 fixedly connected to the top end of the connecting plate 7, a pipe cutter blade 9 fixedly connected to the bottom end of the telescopic movable component 8, and a bottom support component 10 provided at the bottom end of the pipe cutter frame 1.
[0028] Among them, there are two limiting components 6, which are symmetrically distributed on the outside of the moving frame 5. The bottom end of the pipe cutting blade 9 is toothed. The top end of the bottom support component 10 is movably connected to the PE pipe body 11. The top end of the rotating threaded rod 3 is fixedly connected to the protective plate 12.
[0029] The presence of two limiting components 6 improves the stability of the moving frame 5 and effectively prevents the moving frame 5 from shifting position during movement.

The outer sides of the first gear 41 and the outer sides of the second gear 44 mesh with each other.
[0031] Starting the power motor 43 will cause the second gear 44 to rotate, which in turn will drive the rotating threaded sleeve 2 to rotate through the first gear 41, allowing the rotating threaded rod 3 to move up and down.
[0032] The limiting component 6 includes a limiting sleeve 61 fixedly connected to the outside of the movable frame 5, a limiting rod 62 fixedly connected to the inside of the pipe cutter frame 1, and the outside of the limiting rod 62 slidably connected to the inside of the limiting sleeve 61.
[0033] The limiting component 6 can restrict the position of the movable frame 5.

[0035] The telescopic moving component 8 allows the pipe cutting blade 9 to move left and right, thereby improving the overall pipe cutting effect.
[0036] The bottom support assembly 10 includes a support frame 101 that is fixedly installed at the bottom of the pipe break frame 1 by bolts, and an arc plate 102 is fixedly connected to the top of the support frame 101.
[0037] The bottom support component 10 can restrict the position of the bottom end of the PE pipe body 11.
[0038] Working principle:
[0039] When it is necessary to cut the PE pipe body 11, place the PE pipe body 11 on the top of the arc plate 102, and then start the power motor 43 to make the second gear 44 rotate. Then, the first gear 41 will drive the rotating threaded sleeve 2 to rotate, which will make the rotating threaded rod 3 move up and down, and then the moving frame 5 will move down. During the downward movement of the moving frame 5, the telescopic cylinder 81 can be activated to make the pipe cutting blade 9 move left and right, and then the pipe cutting blade 9 can cut the PE pipe body 11.
