Tensioning mechanism for paper printing

Abstract

This utility model discloses a tensioning mechanism for paper printing, relating to the field of paper printing technology. It includes a printing press with support plates mounted on both sides. A tensioning assembly is mounted on the top of the support plates. The tensioning assembly includes a first telescopic rod mounted on the top of the support plates, a lifting platform mounted on the top of the first telescopic rod, and symmetrically distributed support frames mounted on the top of the lifting platform. This utility model is equipped with an electric adjusting rod. The lifting platform is fixed to the inner electric adjusting rod, ensuring that the extension and retraction of the electric adjusting rod drives the top support frame to move up and down to adjust the height. The support frame supports the inner rotating shaft and support roller. A motor is controlled to rotate the output support roller, causing the paper to move above the support roller.

[0025] The printing press 1 is fixedly connected to the support plate 2 on both sides to ensure the stability of the support plate 2. The support plate 2 is fixed to the top first telescopic rod 3 to ensure the smooth operation of the first telescopic rod 3. The extension and retraction of the first telescopic rod 3 drives the top lifting platform 4 to adjust the height. The lifting platform 4 is fixed to the top support frame 5 to ensure the stability of the support frame 5. The support frame 5 supports the inner support shaft, and the support shaft supports the outer guide wheel 6 to ensure the smooth rotation of the guide wheel 6. The paper passes under the guide wheel 6 to facilitate the movement of the paper.

[0026] The lifting platform 4 is fixed to the inner electric adjusting rod 7 to ensure the smooth operation of the electric adjusting rod 7. The extension and retraction of the electric adjusting rod 7 drives the top support frame 8 to move up and down to adjust the height. The support frame 8 supports the inner rotating shaft and support roller 10. The control motor 9 drives the output end support roller 10 to rotate, and the paper moves above the support roller 10. The support frame 8 is fixed to the support platform 11 to ensure the stability of the support platform 11. The support platform 11 supports the inner electric push rod 12. The extension and retraction of the electric push rod 12 drives the bottom lifting seat 13 to move up and down. The lifting seat 13 is inside the inner assembly shaft 14. The assembly shaft 14 rotates smoothly inside the lifting seat 13. The assembly shaft 14 supports the outer lower pressure roller 15. The lower pressure roller 15 rests on the top of the paper.

[0029] Working principle: The output end of the servo motor 17 is connected to the first support member 18, and the front end of the second telescopic rod 20 is connected to the second support member 22. The first support member 18 and the second support member 22 cooperate to support the paper take-up roller 19. When the servo motor 17 runs, it drives the first support member 18 to rotate, which in turn drives the paper take-up roller 19 to rotate. The paper take-up roller 19 then drives the second support member 22 to rotate, ensuring the smooth rotation of the paper take-up roller 19. The paper take-up roller 19 rotates to output paper and to take up paper. When disassembly is required, the second telescopic rod 20 shortens, causing the second support member 22 to move. The second support member 22 moves inside the groove 21, making it convenient for the user to disassemble the paper. The take-up roller 19 and the electric adjusting rod 7 extend and retract, causing the top support frame 8 to move up and down to adjust the height. The support frame 8 supports the inner rotating shaft and the support roller 10. The control motor 9 runs, causing the output support roller 10 to rotate. The paper moves above the support roller 10. The support frame 8 is fixed to the support platform 11 to ensure the stability of the support platform 11. The support platform 11 supports the inner electric push rod 12. The electric push rod 12 extends and retracts, causing the bottom lifting seat 13 to move up and down. The lifting seat 13 is inside the inner assembly shaft 14. The assembly shaft 14 rotates smoothly inside the lifting seat 13. The assembly shaft 14 supports the outer lower pressure roller 15. The lower pressure roller 15 presses against the top of the paper. The height of the support frame 8 is adjusted, thereby adjusting the paper tension.
