[0020] Preferably, the method for using the pipeline cutting device that is easy to clean comprises the following steps:

[0021] Step 1: Fix the clamp guide rail to the edge of the platform. After completion, insert the pipe to be cut into the clamp gap between the two sliders on the clamp guide rail. The insertion distance is determined according to the cutting requirements.

[0022] Step 2: After the pipe is inserted, rotate the rotating head at one end of the clamp seat guide rail to drive the forward screw and the reverse screw rod inside the clamp seat guide rail to rotate, so that the first slider and the second slider on the forward screw rod and the reverse screw rod move closer to the center, and use the positive triangular clamping piece on the first slider clamp seat and the inverted triangular clamping piece on the second slider clamp seat to stagger and clamp the pipe to achieve fixation;

[0023] Step 3: Rotate the rotating block on the top of the cutting seat, and use the transmission effect of the first screw sleeve at the lower end of the rotating block and the first screw rod to drive the upper blade seat to move downward. At the same time, when the rotating block drives the first screw sleeve to rotate, the driving gear on the outer wall of the first screw sleeve can mesh with the driven gears on both sides for transmission, and the driven gear drives the internal second screw rod to rotate, so that the second screw and the second screw sleeves on both sides of the lower blade seat are driven to move upward until the upper cutting blade in the upper blade seat and the lower cutting blade in the lower blade seat fit the pipe wall;

[0024] Step 4: Start the direct drive motor and the asynchronous motor. The output end of the direct drive motor is driven by the upper cutting blade to drive it to rotate. The output end of the asynchronous motor is driven by the first bevel gear at the front end of the lower cutting blade through the second bevel gear to drive it to rotate. At the same time, the turntable on one side of the rotating disk is manually rotated to drive the gear at the rear end of the turntable to rotate, and the gear meshes with the rack on the outer wall of the rotating disk to drive the entire cutting seat to rotate. When rotating half a circle, the positions of the upper cutting blade and the lower cutting blade are interchanged to complete the cutting of the pipeline. While the asynchronous motor uses the second bevel gear to drive the lower cutting blade to rotate, the second bevel gear is simultaneously driven by the third bevel gear on both sides, and the internal transmission rod is driven by the third bevel gear to rotate, so that the exhaust impeller at one end of the transmission rod runs, so that the dust collecting chambers on both sides of the cutting position generate exhaust suction, which continuously attracts debris generated during cutting, and the impurities containing iron components entering the dust collecting chamber can be adsorbed by the electromagnetic rod and can be recycled.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention sets dust collecting chambers on both sides of the cutting seat. When the asynchronous motor drives the lower cutting blade to rotate using the second bevel gear, the second bevel gear is simultaneously transmitted with the third bevel gears on both sides. The third bevel gear drives the internal transmission rod to rotate, so that the exhaust impeller at one end of the transmission rod rotates, so that the dust collecting chambers on both sides of the cutting position generate exhaust suction force, which continuously attracts the debris generated during cutting to enter. The impurities containing iron components entering the dust collecting chamber can be adsorbed by the electromagnetic rod and can be recycled, thus avoiding the situation where the debris splashes, making cleaning more convenient. This solves the problem that the existing device can only prevent the splashing debris from entering the cutting box during use, but the debris will still splash everywhere, increasing the burden of later environmental cleaning.

[0027] 2. By setting an upper blade seat linked with the lower blade seat, before cutting, the rotating block on the top of the cutting seat is rotated, and the transmission effect of the first screw sleeve at the lower end of the rotating block and the first screw is utilized to drive the upper blade seat downward. At the same time, when the rotating block drives the first screw sleeve to rotate, the driving gear on the outer wall of the first screw sleeve can mesh with the driven gears on both sides for transmission, and the driven gear drives the second screw rod inside to rotate, so that the second screw and the second screw sleeves on both sides of the lower blade seat are transmitted, and the lower blade seat is driven to move upward until the upper cutting blade in the upper blade seat and the lower cutting blade in the lower blade seat are in contact with the pipe wall, and the direct drive motor is started. The machine and asynchronous motor, the output end of the direct-drive motor is transmitted to the upper cutting blade to drive it to rotate, the output end of the asynchronous motor is transmitted to the first bevel gear at the front end of the lower cutting blade through the second bevel gear, and drives it to rotate. At the same time, the turntable on one side of the rotating disk is manually rotated to drive the gear at the rear end of the turntable to rotate, and the gear meshes with the rack on the outer wall of the rotating disk to drive the entire cutting seat to rotate. When it rotates half a circle, the positions of the upper cutting blade and the lower cutting blade are interchanged to complete the cutting of the pipeline. Compared with the traditional planetary pipe cutting machine, it only needs to rotate half a circle to complete the cutting of a pipeline, and the processing efficiency is doubled.

7. The method for using the easy-to-clean pipe cutting device according to claim 6, characterized in that: The following steps are involved: Step 1: Fix the clamp seat guide rail (19) to the edge of the platform. After completion, insert the pipe to be cut into the gap between the clamp seats (40) on the two sliders of the clamp seat guide rail (19). The insertion distance is determined according to the cutting requirements. Step 2: After the pipe is inserted, the rotating head (47) at one end of the clamp seat guide rail (19) is rotated to drive the forward screw rod (45) and the reverse screw rod (46) inside the clamp seat guide rail (19) to rotate, so that the first slider (38) and the second slider (39) on the forward screw rod (45) and the reverse screw rod (46) are moved toward the center, and the positive triangular clamping piece (41) on the clamp seat (40) of the first slider (38) and the inverted triangular clamping piece (42) on the clamp seat (40) of the second slider (39) are used to clamp the pipe in a staggered manner to achieve fixation; Step 3: Rotate the rotating block (4) at the top of the cutting seat (2), and use the transmission effect of the first screw sleeve (5) and the first screw rod (6) at the lower end of the rotating block (4) to drive the upper blade seat (9) to move downward. At the same time, when the rotating block (4) drives the first screw sleeve (5) to rotate, the driving gear (24) on the outer wall of the first screw sleeve (5) can mesh with the driven gears (25) on both sides to drive, and the driven gear (25) drives the internal second screw rod (14) to rotate, so that the second screw rod (14) and the second screw sleeves (13) on both sides of the lower blade seat (12) are driven to move upward until the upper cutting blade (11) in the upper blade seat (9) and the lower cutting blade (17) in the lower blade seat (12) are in contact with the pipe wall; Step 4: Start the direct drive motor (10) and the asynchronous motor (16), the output end of the direct drive motor (10) is transmitted to the upper cutting blade (11) to drive it to rotate, the output end of the asynchronous motor (16) is transmitted to the first bevel gear (27) at the front end of the lower cutting blade (17) through the second bevel gear (28) to drive it to rotate, and at the same time, the turntable (23) on one side of the rotating disk (1) is manually rotated to drive the gear (22) at the rear end of the turntable (23) to rotate, meshing with the rack (18) on the outer wall of the rotating disk (1) to drive the entire cutting seat to rotate. When rotating half a circle, the upper cutting blade (11) and the lower cutting blade (17) are rotated. ) positions are interchanged to complete the pipe cutting work. When the asynchronous motor (16) uses the second bevel gear (28) to drive the lower cutting blade (17) to rotate, the second bevel gear (28) is simultaneously driven by the third bevel gear (29) on both sides. The third bevel gear (29) drives the internal transmission rod (30) to rotate, so that the exhaust impeller (34) at one end of the transmission rod (30) operates, so that the dust collecting chambers (121) on both sides of the cutting position generate exhaust suction force, continuously attracting the debris generated during cutting to enter, and the impurities containing iron components entering the dust collecting chamber (121) can be adsorbed by the electromagnetic rod (35) and can be recycled.
