The roundness contrast induction mechanism 3 comprises a telescopic induction component 33 and an induction roller component 34, the telescopic induction component 33 is arranged on the main body frame 23, and the induction roller component 34 is arranged on the telescopic induction component 33.

The negative feedback regulation and control mechanism 4 comprises a hydraulic passage component 41 and a pressure feedback component 42, wherein the hydraulic passage component 41 is arranged on the frame mechanism 2, and the pressure feedback component 42 is arranged in the hydraulic passage component 41; the hydraulic passage assembly 41 comprises a feedback cavity 43, a first hydraulic pipeline 44 and a second hydraulic pipeline 45, wherein the feedback cavity 43 is arranged on the feedback bracket 50, the first hydraulic pipeline 44 is arranged between the sensing cavity 36 and the feedback cavity 43, and the second hydraulic pipeline 45 is arranged between the fixed cavity 9 and the feedback cavity 43.

The current state of the winding roller 29 can be determined by the amount of displacement of the current levitation contact 48 with respect to the previous cycle being known by the relative position feedback between the levitation contact 48 and the slide switch 49, and the levitation contact 48 does not have the ability to automatically return to the original position as the telescopic squeeze tube 11 is telescopic, but the same effect can be achieved by circularly setting the reference point in the coordinate system of the slide switch 49.
As shown in fig. 13 and 14, (a) is in a state where the winding roller 29 is in a perfect circle, and (b) is in a state where the winding roller 29 is pressed into a vertical oval shape when the pressure of the pressing roller 14 is excessive, the small circle on the side indicates the pressing roller 14, the small circle on the top indicates the sensing roller 39, and in the state (a) the winding roller 29 is increased in diameter but the pressing roller 14 and the sensing roller 39 are slid synchronously, so that the pressure regulating assembly 8 is kept stationary; in the state (b), the pressure of the extrusion roller 14 is too large, and the two dotted circles with different diameters in the state (b) respectively indicate the right circular track where the extrusion roller 14 and the sensing roller 39 are located, at this time, the suspension contact 48 is already biased towards the direction approaching the self-adaptive pressing mechanism 1, namely S > S0, at this time, the extrusion force of the extrusion roller 14 on the winding roller 29 can be reduced by rotating the adjusting motor 15 to retract the telescopic extrusion cylinder 11, and the winding roller 29 can be restored to the original shape.
In specific use, first the user needs
The roundness comparison sensing mechanism 3 may be provided with two or three groups, if two groups are provided, as shown in the drawing, if three groups are provided, one group is also provided opposite to the extrusion roller 14, and at this time, the sum of the piston areas of the three groups of sensing piston rods 37 is equal to the area of the annular piston disc 19; in summary, the sum of the piston areas of the groups of induction piston rods 37 is equal to the area of the annular piston disc 19, so that the pressing force of the groups of induction rollers 39 on the winding roller 29 is smaller than the pressing force of the pressing roller 14 on the fixed cavity 9, that is, the winding roller 29 cannot be pressed into a transverse oval shape;
the adjusting motor 15 has two driving modes, namely, the first is automatically controlled through a suspension contact 48 and a sliding switch 49, and the second is actively controlled through a control module; in the normal working state, the diameter of the winding roller 29 gradually increases along with the winding, but is always a perfect circle, so that the extrusion roller 14 and the induction roller 39 are contacted with the winding roller 29 in the normal working state and have the same sliding speed; the piston plate 46 moves synchronously towards the middle during the synchronous sliding of the squeeze roller 14 and the sensor roller 39, so that the levitation contact 48 remains stationary;
with slow sliding of the piston plate 46, the elastic force of the feedback spring 47 is also increased slightly, the position coordinate of the suspension contact 48 relative to the sliding switch 49 is set as an initial reference point S0 at the beginning, then the position coordinate S of the current suspension contact 48 relative to the sliding switch 49 is circularly read, and the S and S0 are compared in each cycle;
if S is smaller than S0, it means that the induction roller 39 is in contact with the winding roller 29, and the extrusion roller 14 is not in contact with the winding roller 29, which is not generally the case, if the induction roller is only removed after the winding of the previous winding roller 29 is completed, and the diameter of the new winding roller 29 is too small, the telescopic extrusion barrel 11 is controlled to extend from the hollow sliding sleeve 10 by the rotation of the adjusting motor 15, and the extending amplitude corresponds to the difference between S and S0;
if S is equal to S0, the slip amplitude of the squeeze roller 14 and the induction roller 39 is equal, and the adjusting motor 15 does not need to act;
if S is greater than S0, the winding roller 29 assumes a longitudinal oval shape as shown in (b) of fig. 13, which means that the pressure of the extrusion roller 14 against the winding roller 29 is too high, and at this time, the extrusion roller 14 and the sensing roller 39 do not slide synchronously, specifically, the sliding amplitude of the extrusion roller 14 is smaller than that of the sensing roller 39, so that the amount of liquid entering the feedback cavity 43 from the sensing cavity 36 is greater than that entering the feedback cavity 43 from the fixed cavity 9, and therefore, relative to the fixed sliding switch 49, the suspension contact 48 inevitably slides towards the adaptive pressing mechanism 1, at this time, the telescopic extrusion cylinder 11 is controlled to retract into the hollow sliding sleeve 10 by the rotation of the adjusting motor 15, the retracting amplitude corresponds to the difference between S and S0, and the winding roller 29 is restored to a perfect circle;
step four: the current value of S is assigned to S0, the reference point S0 is refreshed according to the current position of the hover contact 48, and the next cycle is entered after one period.
