As shown in FIG. 1, the utility model discloses a to roller mechanism, include to roller 1 and to roller axle 2, to roller 1 cover locate to roller axle 2 on, to roller 1 including first terminal surface and second terminal surface.

The counter roller mechanism further comprises a first blocking portion and a second blocking portion 6, the first blocking portion is used for limiting the counter roller 1 to move along a first direction, the first direction is the X direction in the figure 1, the second blocking portion 6 is used for limiting the counter roller 1 to move along a second direction, and the second direction is the direction opposite to the X direction in the figure 1.

As shown in fig. 2, the counter roller mechanism further includes positioning holes 3 and positioning pins 4 matched with the positioning holes 3, the positioning holes 3 and the positioning pins 4 are respectively disposed on the first end surface and the first blocking portion, the number of the positioning holes 3 is plural, and the number of the positioning pins 4 is smaller than or equal to the number of the positioning holes 3.

As shown in fig. 1, the embossed seal 8 is arranged on the embossed seal roller 7, the embossed seal 8 is used for printing information on the trademark paper, and the area of the counter roller 1, which is in contact with the embossed seal 8, is a supporting area. When the counter roller mechanism is in an operating state (rotating state), the counter roller mechanism keeps the circumferential relative position of the counter roller 1 and the counter roller shaft 2 unchanged through the matching of the positioning pin 4 and the positioning hole 3, and the position of a support area in contact with the steel seal 8 on the counter roller 1 is kept unchanged. After the steel seal roller 7 and the symmetrical roller 1 run for a period of time, the supporting area can be abraded under the influence of the acting force of the steel seal 8, so that the gap between the supporting area and the steel seal 8 is increased, and the printing effect of the label paper is influenced. Stopping the machine, releasing the limitation of the second blocking part 6 on the movement of the counter roller 1 along the second direction, pushing the counter roller 1 towards the second direction to pull the positioning pin 4 out of the positioning hole 3, then rotating the counter roller 1 around the axis of the counter roller 1 by a certain angle, pushing the counter roller 1 towards the first direction to insert the positioning pin 4 into the positioning hole 3 again, and finally recovering the limitation of the second blocking part 6 on the movement of the counter roller 1 along the second direction. At this time, the position of the support region on the counter roll 1 is changed, and the changed support region is not worn yet, so that the counter roll 1 can be continuously used.

Alternatively, the positioning holes 3 are uniformly arranged around the axis of the counter roller 1.

Optionally, the first blocking portion is disposed on the counter roller shaft 2 and abuts against the first end surface, so that the first blocking portion can conveniently limit the movement of the counter roller 1 along the first direction.

Optionally, the first blocking portion is a flange 5, and the flange 5 has a larger contact area with the first end surface, so that the restriction on the movement of the liner roller 1 in the first direction can be better realized.

Optionally, the second blocking portion 6 includes a fixing portion 61 and a stopper.

Optionally, the fixing portion 61 is disposed on the counter roller shaft 2, and for the convenience of installing the counter roller 1 on the counter roller shaft 2, the fixing portion 61 is detachably connected to the counter roller shaft 2, specifically, the fixing portion 61 is connected to the counter roller shaft 2 through a key or a jack screw, and when the fixing portion 61 is connected to the counter roller shaft 2 through a key, the fixing portion 61 is prevented from moving on the counter roller shaft 2 along the first direction or the second direction by a retaining ring.

Optionally, the limiting member is an elastic member, which facilitates the convenient completion of the position change of the support region on the counter roller 1.

Alternatively, the elastic member is a compression spring 62, the compression spring 62 is sleeved on the counter roller shaft 2, one end of the compression spring 62 abuts against the second end face, and the other end of the compression spring 62 abuts against the fixing portion 61.

When the supporting area is worn to be invalid, the machine is stopped to enable the counter roller mechanism to be in a static state, the positioning pin 4 can be pulled out of the positioning hole 3 by directly pushing the counter roller 1 to the second direction, after the counter roller 1 rotates around the axis of the counter roller 1 by a certain angle, the counter roller 1 does not need to be pushed to the first direction by using the pressure spring 62, the counter roller 1 can automatically move to the first direction under the action of the elastic force of the pressure spring 62, the positioning pin 4 is inserted into the positioning hole 3 again, and therefore the position change of the supporting area on the counter roller 1 is conveniently completed.

Optionally, the positioning holes 3 are provided on the first end surface, and the number of the positioning holes 3 is 8. The number of the positioning holes 3 is equal to the number of the supporting areas on the counter roll 1, and in practical application, the number of the positioning holes 3 can be set according to the area of the circumferential surface of the counter roll 1 and the occupied area of the supporting areas on the circumferential surface of the counter roll 1, so that the number of the supporting areas is increased as much as possible, and the supporting areas are ensured not to interfere with each other, thereby increasing the utilization rate of the symmetrical roll.

Optionally, the positioning pins 4 are disposed on the first blocking portion, the number of the positioning pins 4 is 1, the matching between one positioning pin 4 and the positioning hole 3 is sufficient to keep the circumferential relative position of the counter roller 1 and the counter roller shaft 2 unchanged, and a situation that the plurality of positioning pins 4 are not easily aligned with the plurality of positioning holes 3 at the same time in the process of changing the position of the supporting region due to the excessive number of the positioning pins 4 can be avoided.

Optionally, the diameters of the positioning hole 3 and the positioning pin 4 are both 5mm, and the positioning pin 4 is in clearance fit with the positioning hole 3.

When the counter roller mechanism is in an operating state (rotating state), the counter roller mechanism keeps the circumferential relative position of the counter roller 1 and the counter roller shaft 2 unchanged through the matching of the positioning pin 4 and the positioning hole 3, and the position of a support area in contact with the steel seal 8 on the counter roller 1 is kept unchanged. When the supporting area is worn to be invalid, stopping the machine to push the counter roller 1 towards the second direction, so that the positioning pin 4 is pulled out of the positioning hole 3, rotating the counter roller 1 around the axis of the counter roller 1 by a certain angle, then pushing the counter roller 1 towards the first direction is not needed, the counter roller 1 automatically moves towards the first direction under the action of the elastic force of the pressure spring 62, and the positioning pin 4 is inserted into the positioning hole 3 again, so that the position change of the supporting area on the counter roller 1 is completed. At this time, the changed support region is not worn yet, and the counter roller 1 can be used continuously.
