[0028] The inner part of the rotating roller 4 is fixedly provided with two fixed barrels 15, and the two fixed barrels 15 are respectively provided with a tensioning mechanism. The tensioning mechanism comprises two top plates 16 which penetrate through the fixed barrel 15 and are in sliding connection with the fixed barrel 15. The two top plates 16 are symmetrically distributed at both ends of the fixed barrel 15. The side, away from each other, of the two top plates 16 is respectively fixedly connected with a push block 17. The rotating roller 4 is provided with two groups of push mechanisms which correspond to the two fixed barrels 15 respectively. The push mechanism comprises two extrusion blocks 7 which are in sliding connection with the rotating roller 4. The two extrusion blocks 7 are symmetrically distributed at both ends of the fixed barrel 15. The two extrusion blocks 7 are respectively in sliding connection with the push block 17 on the corresponding side, and the push block 17 is located in the extrusion block 7. The side, close to each other, of the two extrusion blocks 7 is respectively fixedly connected with a spring 8 on the outer wall of the fixed barrel 15, and the spring 8 is sleeved on the outside of the top plate 16 on the corresponding side. The inner part of the rotating roller 4 is provided with two extrusion grooves 10 which correspond to the two groups of push mechanisms respectively. The extrusion groove 10 is located between the two extrusion blocks 7 on the corresponding side. The side, close to each other, of the two extrusion blocks 7 is respectively fixedly connected with an extrusion column 9. The extrusion column 9 is in sliding connection with the extrusion groove 10. The inner part of the rotating roller 4 is provided with two hydraulic grooves 13 which are located between the two extrusion grooves 10. The two hydraulic grooves 13 are respectively in sliding connection with a pressing plate 12. The side, away from each other, of the two pressing plates 12 is respectively fixedly connected with a push plate 11. The push plate 11 is in sliding connection with the extrusion groove 10 on the corresponding side, and the push plate 11 is located between the two extrusion columns 9 on the corresponding side. The hydraulic groove 13 is filled with hydraulic oil. The fixed barrel 15 is in communication with the hydraulic groove 13 on the different side through the communication groove 14.

[0029] When the other end of the conveying belt deviating direction is separated from the extrusion block 7, the conveying belt releases the extrusion on the extrusion block 7, so that the extrusion block 7 slides along the inner wall of the rotating roller 4 to the outside of the rotating roller 4 under the action of the spring 8. The extrusion block 7 drives the extrusion column 9 to slide along the inner wall of the extrusion groove 10 from inside to outside, so that the internal pressure of the extrusion groove 10 decreases. Under the action of negative pressure, the push plate 11 generates suction force, so that the push plate 11 drives the corresponding pressing plate 12 to move synchronously. The movement of the pressing plate 12 extrudes the hydraulic oil in the corresponding hydraulic groove 13 to enter the other side of the fixed barrel 15 through the communication groove 14. The internal pressure of the other side of the fixed barrel 15 increases, so that the top plate 16 is driven by the thrust to move away from the rotating roller 4. Until the end of the push block 17 is higher than the end of the extrusion block 7. At this time, the push block 17 corresponding to the conveying belt deviating direction will increase the tension of the conveying belt, so that the conveying belt cannot continue to deviate, avoiding that the conveying belt deviates too much to affect the production process.

[0030] The utility model discloses when the conveying belt is installed on the outer surface of the rotating roller 4, the tension of the conveying belt can extrude the extruding block 7 and the push block 17, and then the extruding block 7 and the push block 17 are retracted from outside to inside along the inner wall of the rotating roller 4 until the end surface of the extruding block 7 and the push block 17 is flush with the outer surface of the rotating roller 4.

[0031] When the conveying belt is in the process of conveying the workpiece needing printing into the printing workshop 2, the offset condition is inevitable, at this moment, the conveying belt can produce the offset along the outer surface of the rotating roller 4, when the conveying belt on the rotating roller 4 offsets to one side, can contact with the fixed ring 5 on the rotating roller 4, and because the fixed ring 5 is provided with a plurality of friction strips 6, and the friction strip 6 is arranged according to the rotating direction of the rotating roller 4, and then when the conveying belt produces the offset and contacts with the friction strip 6, the friction of the conveying belt on the offset direction side can increase, so that the friction strip 6 produces the reaction force on the offset direction of the conveying belt, and then the friction force produced by the friction strip 6 can reset the conveying belt, and reduce the offset problem of the conveying belt.

[0032] When the offset of the conveying belt cannot be reset by the friction strip 6, the other end of the offset direction of the conveying belt can be separated from the extruding block 7 at this moment, the extruding block 7 is extruded by the conveying belt at this moment, so that the extruding block 7 slides from inside to outside along the inner wall of the rotating roller 4 under the action of the spring 8, the extruding block 7 slides and drives the extruding column 9 to move synchronously, so that the extruding column 9 slides from inside to outside along the inner wall of the extruding groove 10, the extruding column 9 slides and makes the internal pressure of the extruding groove 10 decrease, so that the suction force is generated on the push plate 11 under the action of the negative pressure, the push plate 11 slides from inside to outside along the inside of the extruding groove 10, the push plate 11 slides and drives the pressing plate 12 to move synchronously, so that the pressing plate 12 slides from inside to outside along the inner wall of the hydraulic groove 13, because the one end of the pressing plate 12 close to the push plate 11 is provided with the hydraulic oil in the hydraulic groove 13, so that the hydraulic oil pressure in the hydraulic groove 13 increases when the pressing plate 12 slides, at this moment, the hydraulic oil in the hydraulic groove 13 can enter the fixed cylinder 15 corresponding to the offset direction of the conveying belt through the communication groove 14, at this moment, the internal pressure of the fixed cylinder 15 increases, so that the hydraulic oil in the fixed cylinder 15 generates the thrust force on the top plate 16, the top plate 16 slides from inside to outside along the inner wall of the fixed cylinder 15, the top plate 16 slides and drives the push block 17 to move synchronously, so that the push block 17 slides along the inner wall of the extruding block 7, until the end of the push block 17 is higher than the end of the extruding block 7, at this moment, the push block 17 corresponding to the offset direction of the conveying belt can increase the tension of the conveying belt, so that the conveying belt cannot continue to offset, the offset distance of the conveying belt can be adjusted according to the actual situation by the subsequent staff, and the offset of the conveying belt is avoided.
