It is widely used in hygiene products, household paper products and other fields. The processing environment of dust-free paper usually needs to be kept dust-free or clean.

[0003] In the prior art, most traditional cleanroom paper embossing devices control the overall or partial embossing depth of cleanroom paper through fixed spacing or manual mechanical adjustment. This results in the printing depth of traditional cleanroom paper being either unadjustable or cumbersome to adjust. Furthermore, when dealing with cleanroom paper of different materials and thicknesses, traditional printing devices with fixed spacing or manual mechanical adjustment often require the replacement of printing rollers of different specifications. However, this operation is not only complex but also costly. Therefore, this utility model proposes a cleanroom paper embossing device that facilitates the control of embossing depth to solve the problems existing in the prior art. Summary of the Invention

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-8This utility model provides an embodiment: a dust-free paper embossing device for easy control of embossing depth, including a support base 1, a first base 2, a second base 3, a first movable block 6, a second movable block 7, a second printing roller 19, and a printing cylinder 4. The first base 2 and the second base 3 are fixedly connected to the upper edge of the support base 1, which are symmetrically distributed front and rear. The front and rear ends of the first base 2 and the second base 3 are respectively provided with a first limiting groove 9 and a second limiting groove 13. The front end center of the first base 2 is fixedly connected to two sets of extension frames 8, which are symmetrically distributed vertically and vertically. The two sets of extension frames 8 are rotatably installed between each other. There is a lead screw 10, a threaded sleeve 23 is fixedly connected to the front center of the second movable block 7, a bearing ring 20 is fixedly connected to the front and rear ends of the second printing roller 19, an edge bracket 18 is fixedly connected to the front and rear ends of the bearing ring 20, a printing cylinder 4 is installed between the two sets of edge brackets 18, a number of printing grooves 15 are equidistantly distributed around the outer wall of the printing cylinder 4, and a number of mounting grooves 21 are equidistantly distributed around the outer wall of the bearing ring 20. A miniature electric cylinder 17 is fixedly connected in the mounting groove 21, and a printing protrusion 16 is installed on the output end of the miniature electric cylinder 17.

[0018] The servo adjustment structure composed of servo motor 11 and lead screw 10 realizes the overall lifting and lowering of printing cylinder 4 and second printing roller 19 to adjust the overall printing depth of dust-free paper. Meanwhile, micro electric cylinder 17 controls the extension and retraction of printing protrusion 16, which can adjust the local printing depth of dust-free paper, thereby meeting the needs of printing dust-free paper of different materials and thicknesses.

[0019] Please see Figures 4-8 In this embodiment, the outer wall of the printing protrusion 16 is in contact with the inner wall of the printing groove 15. Two sets of guide rails 12 are symmetrically distributed on the left and right sides at the rear edge of the second base 3. The matching printing protrusion 16 and printing groove 15 can limit the printing protrusion 16 to extend out from the printing groove 15. A first movable block 6 is movably arranged in the second limiting groove 13. Two sets of sliding sleeves 24 are fixedly connected on the rear edge of the first movable block 6. The inner wall of the sliding sleeve 24 is adapted to the guide rail 12. The matching guide rail 12 and sliding sleeve 24 can limit the second movable block 7, which is driven by the lead screw 10 to adjust its height, so as to improve the stability of its pushing the second printing roller 19 and printing cylinder 4.

[0020] Please see Figures 3-7In this embodiment, a servo motor 11 is installed at the upper end of the extension frame 8. The output end of the servo motor 11 passes through the extension frame 8 and is connected to the lead screw 10. The servo motor 11 can drive the lead screw 10 to rotate precisely, thereby driving the second movable block 7 to perform precise lifting and lowering adjustment. The second movable block 7 is movably arranged in the first limiting groove 9. A threaded sleeve 23 is fixedly connected to the center of the front end of the second movable block 7. The threaded sleeve 23 is adapted to the lead screw 10. The adapted threaded sleeve 23 and the lead screw 10 can enable the lead screw 10 to drive the second movable block 7 to perform lifting and lowering adjustment.

[0021] Please see Figures 3-8 In this embodiment, the inner walls of the left and right ends of the first movable block 6 are fitted with the inner wall of the second limiting groove 13, and the inner walls of the left and right ends of the second movable block 7 are fitted with the inner wall of the first limiting groove 9. The first limiting groove 9 and the second limiting groove 13 can provide additional limiting assistance for the second movable block 7 and the first movable block 6 to improve the stability of the second movable block 7 and the first movable block 6 in lifting and adjusting. The first printing roller 5 is rotatably installed between the first base 2 and the second base 3. The rear end of the second base 3 is equipped with the first drive motor 14. The output end of the first drive motor 14 passes through the second base 3 and is connected to the first printing roller 5. The first drive motor 14 can drive the first printing roller 5 to rotate. Two sets of edge brackets 18 are rotatably installed in the second movable block 7 and the first movable block 6, respectively. The rear end of the first movable block 6 is equipped with the second drive motor 22. The output end of the second drive motor 22 passes through the first movable block 6 and is connected to the edge bracket 18. The second drive motor 22 can drive the edge bracket 18 and the second printing roller 19 to rotate.

[0022] Before use, the dust-free paper to be embossed is first introduced into the gap between the first printing roller 5 and the printing cylinder 4 to prepare for the embossing operation. When the embossing depth needs to be adjusted, the servo motor 11 on the extension frame 8 is started to drive the lead screw 10 to rotate. The threaded sleeve 23 drives the second movable block 7 to move up and down in the first limiting groove 9 for adjustment. At the same time, the first movable block 6 moves synchronously along the guide rail 12 through the sliding sleeve 24, thereby driving the printing cylinder 4 and the second printing roller 19 to perform overall lifting and lowering adjustment, thereby changing the distance between the printing cylinder 4 and the first printing roller 5, and thus initially realizing the overall adjustment of the embossing depth. Next, by controlling the micro electric cylinder 17 on the bearing ring 20, the printing protrusion 16 is pushed to extend and retract within the printing groove 15. At the same time, the printing protrusion 16 is in contact with the inner wall of the printing groove 15 to ensure the stability of the extension and retraction adjustment of the printing protrusion 16, thereby adjusting the height of the printing protrusion 16 and achieving precise control of the local embossing depth. During the embossing process, the first drive motor 14 is started, driving the first printing roller 5 to rotate. At the same time, the second drive motor 22 is started, driving the printing cylinder 4 to rotate through the edge bracket 18. The two sets of edge brackets 18 are respectively supported by the second movable block 7 and the first movable block 6 to ensure rotational stability. Then, the dust-free paper is conveyed in the relative rotation of the first printing roller 5 and the printing cylinder 4. The printing protrusion 16 cooperates with the first printing roller 5 to press out a pattern on the paper that matches the shape of the printing groove 15 and the printing protrusion 16, thus completing the embossing work.

[0023] Through the above steps, the servo adjustment structure composed of servo motor 11 and lead screw 10 realizes the overall lifting and lowering of printing cylinder 4 and second printing roller 19 to adjust the overall printing depth of the dust-free paper. Meanwhile, the micro electric cylinder 17 controls the extension and retraction of printing protrusion 16, which can adjust the local printing depth of the dust-free paper, thereby meeting the needs of printing dust-free paper of different materials and thicknesses. This solves the problem that existing dust-free paper embossing devices are unable to perform printing work of different depths on dust-free paper of different materials and thicknesses according to the needs.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
