[0031] A plurality of elastic connecting pieces 11 connect a plurality of connecting blocks 12 and printing plate 13 into a whole track, and drive roller 14 provides power for the rotation of the track, so that the track can rotate on the surface of tubular product 8, so as to print label. Because the elastic connecting piece 11 connected between connecting block 12 and connecting block 12 and connecting block 12 and printing plate 13 has elasticity, when the staff member pulls apart first roof 21 and second roof 22 by hand, the drive roller 14 installed on second roof 22 and the driven roller 15 installed on first roof 21 will have two opposite forces on both ends of the track. The two opposite forces will lengthen the length of the elastic connecting piece 11, so that the distance between the connecting block 12 and the connecting block 12 and the connecting block 12 and the printing plate 13 increases, so that the length of the track formed by the connecting block 12, the printing plate 13 and the elastic connecting piece 11 increases. The length of the track increases, so that the time interval of printing plate 13 contacting the surface of tubular product 8 increases, so as to change the distance between the rolling labels.

[0032] Specifically, a plurality of elastic connecting pieces 11 connect a plurality of connecting blocks 12 and printing plate 13 together, and are combined into a track-shaped structure, and are attached to the outer periphery of drive roller 14 and driven roller 15.

[0033] Only when the connecting block 12 and the printing plate 13 are attached to the driving wheel and the driven wheel, the whole can rotate, so as to achieve the purpose of rolling printing on the surface of the pipe 8.

[0034] Specifically, the printing plate 13 is made of flexible material. If the printing plate 13 is not made of flexible material, it cannot be attached to the driving roller 14 and the driven roller 15.

[0035] Specifically, the telescopic mechanism 2 further comprises a first bottom plate 24 and a second bottom plate 25, the first bottom plate 24 is installed at one end of the pipe 8 below the first top plate 21, and the second bottom plate 25 is installed at one end of the pipe 8 below the second top plate 22.

[0036] The first bottom plate 24 and the second bottom plate 25 move together with the first top plate 21 and the second top plate 22, keeping the positions uniform.

[0037] Specifically, the printing mechanism 1 is provided with a plurality of lifting mechanisms 4 on the side, the lifting mechanism 4 comprises a base 41, a lifting rod 42 and a sliding groove 43, the base 41 is installed on the side of the first bottom plate 24 and the second bottom plate 25, the sliding groove 43 is installed on the side of the first top plate 21 and the second top plate 22, and the lifting rod 42 is installed above the base 41 and is in sliding connection with the sliding groove 43.

[0038] When the staff puts the pipe 8 with different diameters into the rolling printing device, the staff can lift and drop the first top plate 21 and the second top plate 22 with the lifting rod 42 as the lifting direction, so as to change the fixed diameter of the rolling printing device, and achieve the purpose of adapting to different diameter pipes 8. The lifting rod 42 slides in the sliding groove 43 to guide the lifting track of the sliding groove 43.

[0039] Specifically, the second top plate 22 is provided with a pigment box 31 and a pigment brush 32 above, the pigment box 31 is installed at one end of the second top plate 22 above the driving roller 14, and the pigment brush 32 is installed at the bottom of the pigment box 31.

[0040] The staff adds rolling printing pigment to the pigment box 31, and when the printing plate 13 moves below the pigment box 31, the pigment brush 32 below the pigment box 31 will brush the pigment brush 32 on the surface of the printing plate 13, helping the printing plate 13 to complete the rolling printing task.

[0041] Specifically, the side of the sliding groove 43 and the end of the first bottom plate 24, the first top plate 21 and the connecting rod 23 are installed with a fixed screw 5. When the staff moves the first top plate 21 and the first bottom plate 24 forward and backward and up and down, the fixed screw 5 is screwed into the inside of the sliding groove 43, the first bottom plate 24 and the first top plate 21. With the continuous screwing of the fixed screw 5 into the inside of the sliding groove 43, the first bottom plate 24 and the first top plate 21, the pressure of the fixed screw 5 and the contact surface of the connecting rod 23 and the lifting rod 42 also gradually increases, thereby locking the position of the connecting rod 23 and the lifting rod 42 inside the sliding groove 43, the first bottom plate 24 and the first top plate 21, and keeping the current position relationship between the sliding groove 43, the first bottom plate 24 and the first top plate 21 and the lifting rod 42 and the connecting rod 23, completing the fixation of the pipe 8.

[0042] Specifically, the first bottom plate 24 and the second bottom plate 25 are installed with a transmission rod 6 on the side close to the pipe 8. The transmission rod 6 helps the pipe 8 move inside the rolling device to complete the rolling work.

[0043] Specifically, a drive motor 7 is installed on the rotating shaft of the drive roller 14 and the transmission rod 6 to provide power for the rotation of the drive roller 14 and the transmission rod 6.

[0044] Working principle:

[0045] When the staff starts the rolling work, the height of the first top plate 21 and the second top plate 22 is adjusted according to the diameter of the pipe 8. The staff adjusts the height of the first top plate 21 and the second top plate 22 along the direction of the lifting rod 42. When the staff adjusts the height of the first top plate 21 and the second top plate 22 to the appropriate height, the fixed screw 5 is screwed into the inside of the sliding groove 43 to complete the fixation of the height of the first top plate 21 and the second top plate 22.

[0046] When the staff adjusts the height of the first top plate 21 and the second top plate 22 according to the diameter of the pipe 8, the rolling paint is poured into the paint box 31. Start the drive motor 7, the transmission rod 6 installed on the first bottom plate 24 and the second bottom plate 25 will drive the pipe 8 to move, the drive roller 14 will drive the printing plate 13 and the connecting block 12 to move, and the printing plate 13 will be stained with paint after passing through the paint brush 32. The printing plate 13 stained with paint will continue to move under the drive of the drive roller 14 to complete the rolling of the surface of the pipe 8.

[0047] When the worker wants to change the distance between the roll-printed labels, the worker pulls the first top plate 21 and the second top plate 22 apart by hand, and then the driven roller 15 installed on the first top plate 21 and the driving roller 14 installed on the second top plate 22 will lengthen the length of the elastic connecting piece 11, so that the distance between the connecting block 12 and the connecting block 12, the connecting block 12 and the printing plate 13 is increased, so that the length of the track formed by the connecting block 12, the printing plate 13 and the elastic connecting piece 11 is increased. The length of the track is increased, which causes the time interval of the printing plate 13 in contact with the surface of the pipe 8 to be increased, so as to achieve the purpose of changing the distance between the roll-printed labels.

[0048] When the worker finishes adjusting the distance of the roll-printed labels, the connecting rod 23 which is slidably connected inside the first bottom plate 24 and the first top plate 21 is fixed by using the fixing screw 5.
