When the subsequent tube delivery mechanism is running, the motor starts to drive the driving gear 2 to rotate, and the driving gear 2 drives the tube delivery roller 1 4 to rotate through the driven gear 3, and the driving gear 2 also drives the support wheel 7 to rotate through the gear ring 3 71 When the tube delivery roller 1 4 rotates, it will also drive the tube delivery roller 2 5 to rotate through the gear ring 1 41, and synchronously drive the auxiliary guide wheel 6 to rotate through the transmission belt 8, so as to realize the synchronous operation of multiple rollers, thereby squeezing the hose 10 forward and conveying it. A cleaning structure is also provided at one end of the base plate 1. The cleaning structure includes a vertical plate 91, a support rod 92, a base sleeve 93 and an adjustment structure 94. The vertical plate 91 is welded and fixed to the front surface of the base plate 1, the support rod 92 is welded and fixed to the top of the vertical plate 91, the base sleeve 93 is slidably sleeved on the support rod 92, and the adjustment structure 94 It is arranged between the base sleeve 93 and the support rod 92. A circular hole 95 is penetrated on the surface of the base sleeve 93. An annular brush holder 96 is fixed to the inner wall of the circular hole 95.
