Specifically, the surfaces of the first limiting roller 4, the first adjusting roller 5 and the second adjusting roller 11 are smooth and can rotate independently, and the paper is guided and transported through the cooperation of the first limiting roller 4, the first adjusting roller 5 and the second adjusting roller 11.

As a further explanation of the embodiment, the second limiting roller 15 is disposed at the lower end of one side of the two second brackets 3 far away from the first bracket 2, and the linear distance between the top tangent plane of the second limiting roller 15 and the horizontal plane where the axis of the shaft disc 10 is located is smaller than the radius of the shaft disc 10, so as to ensure that when the second adjusting roller 11 rotates to the lowest position, the paper still keeps the staggered state when passing through between the second adjusting roller 11 and the second limiting roller 15.

In this embodiment, the diameter of the first limiting roller 4 is greater than that of the first adjusting roller 5, the first limiting roller 4 is rotatably connected with the first support 2, and the height of the first limiting roller 4 is greater than that of the initial position of the first adjusting roller 5.

In particular, the first limiting roller 4 is matched with the first adjusting roller 5 to enable the paper to pass through in a staggered mode, and therefore sufficient supporting force can be provided for the paper.

As a further explanation of the present embodiment, when the first regulating roller 5 moves upward to the limit, the paper sheet still maintains the state of being interleaved between the first regulating roller 5 and the first limit roller 4.

In this embodiment, the upper parts of the outer walls of the two first brackets 2 are respectively provided with a telescopic connecting rod 8, the outside of each telescopic connecting rod 8 is wrapped by a return spring 9, and the bottom of each telescopic connecting rod 8 is provided with an adaptor 6; each adapter piece 6 is connected with a limiting groove 7 in a sliding mode, and each limiting groove 7 is formed in one first support 2.

Particularly, the movable track of the adaptor 6 is limited by matching the two telescopic connecting rods with the limiting grooves 7, and the stability of the adaptor 6 in sliding is improved.

As a further description of this embodiment, the return spring 9 can provide a certain buffering effect to avoid paper damage when the adjustment range is too large and the paper is over-stretched.

In this embodiment, a step motor 13 is installed on the upper portion of the outer wall of one of the second brackets 3, and an output shaft of the step motor 13 is connected with one end of a driving screw 14, and the driving screw 14 is installed on the second bracket 3; the driving screw 14 is engaged with the engaging wheel 12, and the engaging wheel 12 is mounted on the outer cross section of one of the shaft discs 10, while the shaft axis of the shaft disc 10 and the shaft axis of the engaging wheel 12 are on the same horizontal straight line.

Specifically, the driving screw 14 is driven to rotate by the stepping motor 13, the meshing wheel 12 is driven to drive the shaft disc 10 to rotate by the driving screw 14, the rotating range of the meshing wheel 12 is controlled by the stepping motor 13, the single rotating maximum range of the meshing wheel 12 is 180 degrees, and the second adjusting roller 11 is prevented from being overturned excessively.

In this embodiment, the two ends of the first adjusting roller 5 are respectively rotatably connected with the two adapters 6, the adapters 6 are connected with the limiting groove 7 in a sliding manner, and the first adjusting roller 5 is matched with the adapters 6, the limiting groove 7 and the telescopic connecting rod 8 to form a sliding structure.

Specifically, when the second adjusting roller 11 rotates upward, the paper is pulled to apply a certain pressure to the first adjusting roller 5 upward, and when the pressure is too large, the resilience force larger than the return spring 9 causes the first adjusting roller 5 and the adaptor 6 to move upward synchronously.

As a further explanation of the present embodiment, the two ends of the first adjustment roller 5 are fixed by the two adapters 6, so as to improve the stability of the first adjustment roller 5 in use.

In this embodiment, the connection mode of the shaft disc 10 and the second bracket 3 is rotational connection, and the shaft axis of the shaft disc 10 and the shaft axis of the second adjusting roller 11 are not on the same horizontal straight line, and the connection mode of the shaft disc 10 and the second adjusting roller 11 is rotational connection; the second adjusting roller 11 is matched with the shaft disc 10 to form a rotating structure.

Specifically, the reel 10 drives the second adjusting roller 11 to rotate circumferentially around the transverse axis of the reel 10 in the rotating process, so as to increase the distance between the second adjusting roller 11 and the first adjusting roller 5, further tension the paper and increase the tension of the paper.

As a further explanation of the present embodiment, the two shaft discs 10 are symmetrically distributed, and one of the shaft discs 10 drives the shaft disc 10 on the other side to synchronously rotate through the second adjusting roller 11.

The utility model discloses a theory of operation is: when the paper roll adjusting mechanism is used, paper sequentially penetrates through the first limiting roller 4, the first adjusting roller 5, the second adjusting roller 11 and the second limiting roller 15 in a staggered mode, and the paper is tensioned, so that the paper is tightly attached to the surfaces of the first limiting roller 4, the first adjusting roller 5, the second adjusting roller 11 and the second limiting roller 15, in the using process, in the process of replacing a new material roll, due to the fact that tolerance exists, the tension of the paper is reduced, at the moment, an external power supply is connected, the stepping motor 13 is started, the driving screw 14 starts to rotate, then the meshing wheel 12 is matched to drive the shaft disc 10 to start to rotate, the second adjusting roller 11 is driven to start to rotate, when the second adjusting roller 11 rotates upwards, the distance between the paper and the first adjusting roller 5 and the second limiting roller 15 is increased until the paper recovers tension, in the adjusting process, when the tension is larger than the elastic force of the reset spring 9 due to excessive adjustment, the paper drives the first adjusting roller 5 to slide upwards, the two adapters 6 are synchronously driven to slide upwards along the two limiting grooves 7, meanwhile, the two telescopic connecting rods 8 drive the reset spring to contract, and the reset spring 9 to make up, and make up too much tension, and make up too much of the excessive adjustment.
