[0016] The present invention provides a circular cutting device for processing corrugated pipes, which has the following beneficial effects: when in use, the blade can be advanced at a uniform speed, and the corrugated pipe can be evenly force applied to the corrugated pipe during cutting, thereby avoiding deformation of the corrugated pipe due to uneven force, and during the cutting process, the corrugated pipe can be stably clamped to avoid the corrugated pipe moving due to force during cutting, which may cause cutting errors, and when in use, corrugated pipes of different diameters can be transported, clamped and cut, thereby improving the applicability of the device and avoiding deformation of the corrugated pipe when transporting the corrugated pipe.

[0017] 1. When the present invention is in use, after the cutting point on the bellows reaches the blade, the cutting motor drives the cutting wheel to rotate, so that the gear ring drives the rotating drum to rotate between the sleeves through the ring groove. At the same time, the telescopic rod can drive the slide to approach the rotating drum slowly and uniformly. When the slide is sleeved on the outside of the rotating drum, the slide can apply pressure to the blade, thereby pressing it to slide in the slide cavity and compressing the buffer spring. The slide groove can limit the blade to prevent it from deflecting during movement. The roller and ball in the slide can make the blade move smoothly in the slide, avoiding the blade from slipping. The friction between the blade and the inner wall of the slide affects the rotation of the drum, and as the slide continues to advance, the blade will continue to and slowly approach the corrugated tube until it contacts and cuts it, thereby cutting corrugated tubes of different diameters. The symmetrical setting of the blade allows the blade to apply uniform force to the corrugated tube, and the slow transportation and advancement of the blade can prevent the corrugated tube from being deformed due to excessive local force. In summary, when in use, the blade can be advanced at a uniform speed, and uniform force can be applied to the corrugated tube during cutting, thereby preventing the corrugated tube from being deformed due to uneven force.

[0018] 2. In the present invention, after the cutting point on the corrugated tube reaches the blade, the clamping motor is started, so that the clamping wheel drives the double gear ring to rotate on the sleeve, thereby causing the synchronous wheel to drive the sleeve to rotate in the rotating groove, and then the threaded rod drives the clamping plate to move out of the receiving groove and close to the corrugated tube until the data detected by the pressure sensor reaches a predetermined value. The clamping motor stops running, so that the clamping plate clamps the corrugated tube symmetrically, avoiding the movement of the corrugated tube under force when cutting the corrugated tube, resulting in cutting errors. The engagement of the double gear ring and the sleeve can avoid the deflection of the double gear during rotation, resulting in the inability of the double gear ring to drive all the synchronous wheels to rotate synchronously, and the symmetrically distributed clamping plates make it possible to stably clamp corrugated tubes of different diameters during processing. In summary, during the cutting process, corrugated tubes of different diameters can be stably clamped, avoiding the movement of the corrugated tube under force during cutting, which may cause cutting errors.

[0019] 3. Before cutting the bellows, the present invention places the bellows between the air wheels and starts the air pump. The air pump can then send air into the air supply pipe. The control valve controls the gas flow direction, allowing the air to flow evenly from the air supply pipe through the diverter pipe into the two air bags, causing the air bags to expand and drive the pneumatic plates to move in opposite directions, thereby driving the pressure plate to apply pressure to the air wheel, causing the air wheel to deform until it is tightly attached to the outside of the bellows. The control valve then closes the passage for the air flow to flow into the air bag. The shaft can limit the pneumatic plate and the pressure plate to prevent them from deflecting during movement, and the flexible material of the air wheel can prevent the bellows from being deformed due to excessive force applied to the bellows. Starting the drive motor can enable the transmission wheel to drive the pressure plate to rotate in opposite directions through the shaft, thereby causing the air wheel to transport the bellows and temporarily stop after reaching the cutting site. Stop conveying. During the cutting process, the air pump is started, and the air in the exhaust slot can be drawn into the filter frame from the air outlet, and then into the air pump from the exhaust slot, and sent from the air supply pipe through the connecting slot into the ventilation slot, and then sprayed out from the nozzle to the bellows, so as to cool the cutting area and the blade, and blow away the debris generated during cutting from the bellows and the blade to prevent the debris from adhering. The blown debris will fall into the exhaust slot with the flow of air and be carried to the filter frame by the air flow. The filter frame filters the air flow and intercepts the debris in the filter frame to prevent the debris from entering the air pump and causing damage to the air pump. When the filter frame is full, the filter frame can be taken out of the placement slot for cleaning. In summary, when in use, corrugated pipes of different diameters can be flexibly conveyed, and the debris generated during cutting can be cleaned and collected. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Referring to Figures 1 to 6The blade 305 is connected with the rotating drum 301 through the sliding cavity 302, the blade 305 is elastically connected with the rotating drum 301 through the buffer spring 304, the sliding drum 306 is connected with the rotating drum 301, the telescopic rod 309 is fixed on the supporting plate 2, the gear ring 310 is engaged with the cutting wheel 311, the sleeve 4 is connected in the middle of the supporting plate 2, the ring groove 5 is formed on the side of the sleeve 4 close to each other, the rotating drum 301 is rotatably connected with the sleeve 4 through the ring groove 5, the gear ring 310 is rotatably connected with the rotating drum 301 through the ring groove 5, the receiving groove 6 is symmetrically formed in the sleeve 4, the rotating groove 7 is formed on one side of the receiving groove 6, the clamping plate 8 is slidably connected in the receiving groove 6, the threaded rod 9 is connected on one side of the clamping plate 8, the pressure sensor is arranged in the clamping plate 8, the sleeve pipe 10 is rotatably connected in the rotating groove 7, the synchronous wheel 11 is connected on one side of the sleeve pipe 10, the double gear ring 12 is arranged on one side of the synchronous wheel 11, the clamping wheel 13 is arranged on one side of the double gear ring 12, the clamping motor 14 is connected on one side of the clamping wheel 13, the sleeve pipe 10 is threadedly connected with the threaded rod 9, the synchronous wheel 11 is engaged with the double gear ring 12, the double gear ring 12 is rotatably connected with the sleeve 4, and the double gear ring 12 is engaged with the clamping wheel 13.

[0030] The specific operation is as follows: in use, when the cutting point on the bellows reaches the blade 305, the cutting motor 312 drives the cutting wheel 311 to rotate, so that the gear ring 310 drives the rotating drum 301 to rotate through the ring groove 5 between the sleeves 4, and the telescopic rod 309 can drive the sliding drum 306 to slowly and uniformly approach the rotating drum 301. When the sliding drum 306 is sleeved on the outside of the rotating drum 301, the sliding drum 306 can apply pressure to the blade 305, so as to compress the buffer spring 304 and slide in the sliding cavity 302. The sliding groove 303 can limit the blade 305 from deviating during movement, and the rollers 307 and the balls 308 in the sliding drum 306 can enable the blade 305 to slide smoothly in the sliding drum 306, avoiding the friction between the blade 305 and the inner wall of the sliding drum 306 affecting the rotation of the rotating drum 301.
