When the pinch roller 46 contacts the top of the heating and ventilation pipeline and the electric saw blade 38 cuts the contact pipeline, the pinch roller 46 rotates due to the friction force between the heating and ventilation pipeline and the pinch roller 46, so that the gear 50 is driven to rotate through the cooperation of the sprocket 42 and the chain 43, the connecting shaft 44 is driven to move along the conveying direction of the heating and ventilation pipeline through the meshing effect of the gear 50 and the insulating spring 21, and the supporting slide rod 37 and the electric saw blade 38 synchronously move along the conveying direction.
In this embodiment, when the warm pipe is conveyed, the supporting roller 34 can be supported, and due to friction force, the supporting roller 34 can rotate along with the supporting roller 34, meanwhile, the rotation speed sensor 35 can monitor the rotation speed of the roller shaft one 36, then the sensing of conveying length is realized according to the rotation speed and time, when the required cutting length is reached, the telescopic device 31 is started, the lifting plate 32 is driven to descend, when the lifting plate 32 descends to cut, the top of the warm pipe is contacted by the first pressing roller 46, then the lifting plate 32 descends continuously, the spring two 48 is compressed, the roller shaft one 36 utilizes the self gravity and the elasticity of the spring two 48 to perform bidirectional clamping stabilization, and at the moment, the friction force of the warm pipe and the pressing roller 46 can enable the pressing roller 46 to rotate, so that the gear 50 is driven to rotate through the cooperation of the sprocket 42 and the chain 43, so that the connecting shaft 44 is driven to move along the conveying direction of the warm pipe through the meshing effect of the gear 50 and the insulating spring 21, so that the supporting slide rod 37 and the electric saw blade 38 move synchronously, and simultaneously the lifting plate 32 descends continuously, and the electric saw blade 38 cuts.
The device supports the pipeline by arranging the support roller 34, so that the pipeline is prevented from being bent due to the increase of bending moment received by the pipeline, and the support roller 34 can be matched with the rotation speed sensor 35 to monitor the conveying length in combination time, so that the sensor can be used for alignment cutting, and the versatility is achieved.
Moreover, the device can be matched with the supporting roller 34 to realize the up-and-down clamping of a heating and ventilation pipeline by arranging the pressing roller 46, so that the pipeline rebound caused by cutting and separating is prevented, and on the other hand, the device can be matched with the linkage assembly 29 to realize the driving of the transverse movement of the electric saw blade 38, so that the power source arrangement is reduced, and the synchronism of the device is improved.
