The turntable can be set to rotate clockwise, so that a leftward force is given to the limiter 5 to form self-locking, and the stability of the rotation of the turntable is further ensured.

Secondly, for the hose conveying device 3, a driving motor on the transmission mechanism 3-3 is started, then the transmission shaft 3-32 drives the belt pulley 3-31 to rotate, the flat gear 3-34 on the belt pulley 3-31 transmits power to the transmission gear 3-25 engaged with the belt pulley, the transmission gear 3-25 obtaining the power drives the linkage shaft 3-26 to rotate, the linkage shaft 3-26 sequentially drives the second rotating shaft 3-22 to rotate, and the first rotating shaft 3-21 engaged with the second rotating shaft 3-22 also synchronously rotates, so that the hose clamping devices arranged on the first rotating shaft and the second rotating shaft (3-21 and 3-22) synchronously transmit the power to convey the hose 6 in the stable pipe 10 to the hose cutter 4.

And finally, for the rubber tube cutter 4, the rubber tube 6 slowly enters the rubber tube cutting platform 4-1 from the rubber tube inlet, when the second sensor detects the mark of the cutting length, the cutter driving device 4-5 is started, and the cutter 4-3 performs cutting action on the rubber tube 6, so that circulation is performed.

Therefore, the present hose cutting device includes: 1. when the rubber tube on the turntable device 1 is used up, the rubber tube is automatically closed, and workers are reminded to replace the rubber tube in time; 2. the hose cutter 4 can intelligently cut off the hose by the central controller and the mark arranged on the hose; 3. when the identification block marked on the tail end of the rubber tube is detected, the rubber tube conveying device 3 and the rubber tube cutter 4 can be intelligently closed by combining the use of the power supply monitor.
