As shown in fig. 1, the number of the guide rollers 3 is at least three, the guide roller 3 close to one side of the upper abutting-against roller 5 is fixed with a U-shaped rod 31, the guide roller 3 is provided with the U-shaped rod 31, so that the U-shaped rod 31 rotates synchronously with the guide roller 3, and the paper after unreeling is well pressed, thereby being beneficial to keeping the paper in a tensioning state in the unreeling process and reducing the probability that the paper becomes fluffy after being separated from the unreeling roller 2.

As shown in fig. 2, the top of the frame body 1 is provided with an installation groove 12, the cross section of the installation groove 12 is rectangular, and the installation groove 12 is provided at a position on one side of the movable block 51 of the upper pressing roller 5 away from the top of the frame body 1. The frame body 1 is provided with an adjusting component 8 for adjusting the position of the upper pressing roller 5, and as shown in fig. 3, the adjusting component 8 comprises a T-shaped block 81, a chute 82, a sleeve 83, a screw 84, a driven bevel gear 85, a vertical plate 86, a rotating rod 87, a driving bevel gear 88 and a crank 89. The cross section of the T-shaped block 81 is T-shaped, the sliding groove 82 is arranged at the position, close to the mounting groove 12, of the top of the fixing plate 11, and the sliding groove 82 is in insertion fit with the vertical portion of the T-shaped block 81, so that the T-shaped block 81 can only move upwards or downwards along the sliding groove 82 in the vertical direction. The sleeve 83 is a cylindrical structure, one end of the sleeve is fixed to the side wall of the T-shaped block 81 far away from the frame body 1, and the end of the upper pressing roller 5 far away from the movable block 51 is rotatably connected with the sleeve 83. The screw 84 has a vertical axis, is disposed on the T-shaped block 81 and is in threaded connection therewith, and the lower end of the screw 84 is rotatably connected with the inner bottom wall of the chute 82. The axis of the driven bevel gear 85 coincides with the axis of the screw 84, and is sleeved on and fixed with the screw 84. The vertical plate 86 is a rectangular plate-shaped structure, and the side walls of both sides thereof are fixed to the side walls of both sides of the mounting groove 12, respectively. The rotation rod 87 is a circular rod, and is rotatably connected to the vertical plate 86 through the vertical plate. The axis of the drive bevel gear 88 coincides with the axis of the rotating rod 87, which is sleeved on and fixed to the rotating rod 87, and the drive bevel gear 88 is engaged with the driven bevel gear 85. One end of the crank 89 is fixed with one end of the rotating rod 87 far away from the driving bevel gear 88, and a rubber sleeve 891 fixed with the crank 89 is sleeved on the crank 89. Rubber sleeve 891 adopts rubber materials to make, and its surface has great coefficient of friction to this makes the frictional force between staff's hand and crank 89 increase, thereby is convenient for the staff to hold the crank 89 firmly and rotate, has reduced the possibility that takes place to skid when the staff holds crank 89. Before labeling the paper to be labeled, a worker needs to penetrate one end of the paper through the gap between the upper pressing roller 5 and the lower pressing roller 4, at the moment, the worker only needs to hold the crank 89 and rotate, so that the rotation rod 87 fixed to the crank 89 and the drive bevel gear 88 fixed to the rotation rod 87 are rotated, at the same time, the driving bevel gear 88 rotates the driven bevel gear 85 engaged therewith, thereby rotating the screw 84 fixed to the driven bevel gear 85, since the circumferential rotation of the T-shaped block 81 is restricted by the slide groove 82, so that the T-shaped block 81 can move upward in the vertical direction in the process, so that the gap between the upper pressing roller 5 and the lower pressing roller 4 is increased, the gap between the upper pressing roller 5 and the lower pressing roller 4 is favorably penetrated by one end of paper by a worker, and the smooth unwinding work of the paper is favorably realized.

As shown in fig. 2, the T-shaped block 81 and the fixing plate 11 are mounted with a fixing assembly 9 for fixing the T-shaped block 81 and the fixing plate 11, and as shown in fig. 3, the fixing assembly 9 includes a countersunk bolt 91 and a threaded hole 92. The axis of the countersunk head bolt 91 is vertical, and it is disposed through the horizontal portion of the T-shaped block 81. Threaded hole 92 is seted up at fixed plate 11 top, and its axis coincides with countersunk bolt 91's axis, and threaded hole 92 and countersunk bolt 91 threaded connection to this be convenient for the staff will last the position control of supporting compression roller 5 and finish the back, screw up countersunk bolt 91 in threaded hole 92, thereby fix T-shaped block 81 and fixed plate 11.

As shown in fig. 1, a horizontally arranged baffle 841 is arranged at the upper end of the screw 84, the bottom surface of the baffle 841 is fixed with the upper end of the screw 84, and the baffle 841 is arranged so as to well limit the T-shaped block 81 and avoid the situation that the T-shaped block 81 slides out of the upper end of the screw 84. Still install on the lateral wall of support body 1 rather than the L shape body of rod 13 of being connected that rotates, the extending direction of the horizontal part of the L shape body of rod 13 with last support the axial direction parallel of compression roller 5, through setting up the L shape body of rod 13 to this has played good pressure effect to the paper after unreeling, is favorable to making the paper keep the tensioning state at the in-process of unreeling, has further reduced the paper and has broken away from the probability that becomes fluffy behind unreeling roller 2.

The implementation principle of the embodiment is as follows: before labelling the paper, the staff only need to adjust the position of last pressure roller 5 through adjusting part 8 for the paper of waiting to label can pass smoothly and support the pressure roller 5 and support the clearance between the pressure roller 4 down, and the staff only needs to adjust the position of last pressure roller 5 once more through adjusting part 8 afterwards, and it can with supporting the pressure roller 4 mating reaction and supporting the paper tightly with this messenger to support the pressure roller 5 under with.

When the position of the upper pressing roller 5 is adjusted by using the adjusting assembly 8, a worker only needs to hold the crank 89 and rotate the crank 87, so that the rotating rod 87 and the driving bevel gear 88 fixed with the rotating rod 87 rotate, the driven bevel gear 85 meshed with the driving bevel gear 88 and the screw 84 fixed with the driven bevel gear 85 rotate, the T-shaped block 81 moves upwards along the vertical direction due to the fact that the circumferential rotation of the T-shaped block 81 is limited by the sliding groove 82, in the process, the sleeve 83 moves upwards along with the T-shaped block 81 synchronously, meanwhile, one end, far away from the movable block 51, of the upper pressing roller 5 moves upwards along with the sleeve 83 synchronously, the gap between the upper pressing roller 5 and the lower pressing roller 4 is increased, and the worker can place paper into the gap between the upper pressing roller 5 and the lower pressing roller 4. After the end of the paper passes through the gap between the upper pressing roller 5 and the lower pressing roller 4, the worker only needs to rotate the crank 89 reversely (opposite to the rotation direction when the gap between the upper pressing roller 5 and the lower pressing roller 4 is enlarged), and according to the above analysis, the same can be known, in the process, the gap between the upper pressing roller 5 and the lower pressing roller 4 is gradually reduced, so that the upper pressing roller 5 is matched with the lower pressing roller 4, the paper is pressed tightly, and the unreeling work is facilitated.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
