Referring to fig. 5 and 12, in the illustration, the lifting mechanism 11 includes an optical axis 28 and two screws 29 rotatably embedded in the bottom of the lifting platform 3, the optical axis 28 and the screws 29 are oriented in the same direction as the rotating shaft 25, the two screws 29 are symmetrically distributed about the optical axis 28, the threads of the two screws 29 are opposite, the outer threads of the screws 29 are sleeved with a moving block, support rods 30 are hinged between the moving block and the device housing 2, the two sets of support rods 30 are distributed in a staggered manner, a fourth transmission belt is installed between the optical axis 28 and the straight rod, a motor 27 is fixedly installed inside the lifting platform 3, a fifth transmission belt is installed between the output end of the motor 27 and the optical axis 28, and when the motor 27 drives the two screws 29 to rotate counterclockwise, the support rods 30 are slowly erected and jack up the lifting platform 3.
The working principle of leveling the position of the material roll automatically is as follows: the general material roll is placed above the lifting platform 3 through a forklift, the situation that the material roll is placed at the central position of the lifting platform 3 cannot be judged, a large error exists between the position of the material roll and the central position, and the material roll is not placed at the central position of the upper end of the lifting platform 3, so that under the jacking of the two adjusting rubber wheels 22, the material roll can be like a lever, and gravity is exerted on the two bearing sliding seats 16 in a heavy way and a light way;
when the material roll is wholly deviated to the left, namely the downward displacement degree of the supporting slide carriage 16 positioned on the left is larger than the downward displacement degree of the right, the sliding block 32 is positioned at the central position in fig. 7, when the downward displacement degree of the supporting slide carriage 16 positioned on the left is larger than the downward displacement degree of the right, the sliding block 32 is pulled by the connecting rod 20 to be deviated to the left to slide, at the moment that the sliding block 32 slides to the left, the clamping block 43 distributed on the right can rapidly move upwards under the action of the tension spring 44 and is attached to the inclined edge step part of the sliding rod 39, after the clamping block 43 on the right no longer limits the clamping gear 37, the motor 27 drives the screw 29 to rotate anticlockwise, when the lifting platform 3 moves upwards through the support rod 30, the optical axis 28 can drive the transmission gear 36 to rotate anticlockwise, because the clamping gear 37 on the left is in a clamping state, namely, the left rotating shaft 25 cannot rotate, at this time, the hemispherical groove 54 in the synchronizing wheel can apply larger pressure to the round-head jack 55, so that the round-head jack 55 retracts into the sleeve block I35, the synchronizing wheel distributed on the outer side of the rotating shaft 25 idles, when the transmission gear 36 rotates anticlockwise to drive the toothed wheel 34 to rotate clockwise, because the latch gear 37 distributed at the rear end of the sleeve block II 53 is not locked, namely, the transmission gear 36 can drive the sleeve block II 53 and the rotating shaft 25 therein to rotate clockwise, and at this time, the latch gear 37 distributed on the outer portion of the left rotating shaft 25 is in a locked state, namely, when the left rotating shaft 25 rotates, the isosceles ladder block 41 retracts into the rotating shaft 25, so that the left rotating shaft 25 idles clockwise, and at this time, the rubber wheel 22 is adjusted to rotate clockwise, so that the left material roll can move to the right;
in the moving process, the displacement amounts of the two bearing sliding seats 16 are gradually consistent, namely the sliding block 32 is gradually reset and moves to the central position of the sliding rail, after the sliding block 32 is reset, the clamping block 43 on the right side can be directly extruded through the inclined edge step portion of the sliding rod 39, so that the clamping block 43 limits the clamping gear 37 again, namely after the material roll moves to the central position, the two rotating shafts 25 are in a limiting and clamping state, at the moment, the toothed groove wheel 34 and the sleeve block I35 idle in the lifting process of the lifting platform 3, namely, the material roll can be automatically moved to the central position in the lifting process of the lifting platform 3, manual repeated adjustment on the transverse position of the material roll is not needed, and the feeding efficiency is improved;
if the whole material roll deviates to the right side of the lifting platform 3, namely the states of the two groups of rotating shafts 25 in the above steps are opposite, the rubber wheel 22 can be adjusted to rotate anticlockwise, and the material roll deviating to the right side moves towards the left.

Example 3
Referring to fig. 11, the present embodiment further illustrates that, for other embodiments, both the tooth surface of the latch gear 37 and the lower end surface of the latch 43 are arc surfaces.
In this embodiment: the reason why the tooth surface of the latch gear 37 and the lower end surface of the latch 43 are arc surfaces is to ensure that the latch 43 cannot be effectively engaged with the latch gear 37 at the first time because the contact surfaces of the latch 43 and the latch are flat surfaces in the descending process, so that the rotating precision of the rotating shaft 25 can be ensured.
