The resilient member 2175 causes the braking member 2173 to reciprocate within the receiving recess 2174, changing the contact pressure and improving the braking effect in such a manner that the inner race of the sleeve 218 contacts the end face of the braking member 2173.

The specific use of the automatic paper receiving frame for the tube rolling machine in this embodiment is as follows:

the paper disc 25 is installed on the paper tape brake disc 21, the paper discs 25 are assembled on the upper paper tape brake disc 21 and the lower paper tape brake disc 21, paper tapes 251 in the two paper discs 25 are sequentially conveyed from the paper tape brake disc 21 to the paper receiving assembly 22 along the transition wheel 26, one paper tape 251 stays on a paper sticking pressing block 2243 of the paper cutting mechanism 224 and is fixed on a part of the paper tape supporting strip 222 through a paper pressing rod 2235, the other paper tape 251 enters the paper tape storage buffer frame 23 through the transition wheel 26 between the paper receiving assembly 22 and the paper tape storage buffer frame 23, and is alternately coiled along the first pulley block 2324 and the second pulley block 2325 from bottom to top in sequence and is externally butted to the pipe coiling machine through the discharging wheel 24;

when the tube coiling machine starts to work and keeps a certain tube coiling speed, the paper output speed of the paper disc 25 keeps consistent with that of the tube coiling machine, at this time, because the paper disc 25 has a larger weight because of the sufficiency of the paper tape 251, the friction force exerted by the paper tape brake disc 21 is also larger, under the combined action of the tension of the pipe coiling machine, the sliding plate 2322 of the paper tape storage buffer frame 23 is located at a position with a higher sliding shaft 2321, at this time, because the sliding plate 2322 is higher than the position of the fixed pulley 2326, two outermost movable pulleys of the first pulley block 2324 are in a failure state, the downward force borne by the sliding plate 2322 is larger, as the paper tape 251 on the paper tray 25 is continuously consumed, the weight of the paper tray 25 becomes smaller, the friction force provided by the paper tape brake disc 21 also becomes smaller gradually, at this time, the sliding plate 2322 descends gradually until the position is lower than the fixed pulley 2326, at this time, the two outermost movable pulleys of the first pulley block 2324 are effective, and the descending trend of the sliding plate 2322 becomes slower;

when the length of the paper tape 251 in the paper tray 25 is not enough, the photoelectric sensor 211 arranged on the mounting bracket 212 converts the information to indicate that the current paper amount is not enough and automatic paper receiving is needed, when the paper receiving assembly 22 obtains a signal, the paper cutting mechanism 224 starts to operate, the vertical power source 2241 drives the fixed seat 2242 to operate in the vertical direction and drives the sticky paper pressing block 2243 to operate, the sticky paper pressing block 2243 displaces the paper tapes in conveying together in the displacement process, and cuts the paper tapes through the blade 2244, because the two paper cutting mechanisms 224 are arranged oppositely, the rebound plectrums 225 connected with the paper cutting mechanisms 224 drive the paper pressing mechanisms 223 positioned at the oblique angles to operate, the original paper tape which is originally pressed and stays on the sticky paper pressing block 2243 of another paper cutting mechanism 224 is loosened, the sticky paper pressing blocks 2243 of the two paper cutting mechanisms 224 are jointed, so that the original paper tape is jointed with a new paper tape, then the paper cutting mechanism 224 is reset;

the adhered paper tape 251 is conveyed continuously, because the paper tape 251 is pulled at the moment of adhesion, the sliding plate 2322 performs a lifting action to buffer, because when the paper tray 25 finishes paper splicing, the sliding plate 2322 is located at a lower position of the sliding shaft 2321, and the paper tray 25 needs a speed-up process to keep the same speed as that of the roller coiling machine, the paper tape 251 in the paper storage mechanism 232 buffers at the moment, because the paper tray 25 on the paper tape brake disc 21 after paper splicing is not consumed, the whole weight is heavy, the friction force is also large, under the combined action of the pulling force of the roller coiling machine, the sliding plate 2322 performs a lifting action to buffer, the roller coiling machine does not need to stop or reduce the speed to influence the roller coiling efficiency, and the whole paper splicing action is finished.
