Detailed Implementation

[0019] Reference Figures 1-3 An embossing mechanism for a printing press, comprising:

[0020] Mounting plate 1, embossing rod 3 is slidably mounted on mounting plate 1, embossing plate 4 is fixedly mounted at the bottom end of embossing rod 3, embossing rod 3 is fixedly connected to printing machine, printing machine can be a commonly used embossing printing machine on the market, printing machine drives embossing rod 3 to move, so that embossing plate 4 moves together to perform embossing process, after embossing is completed, embossing plate 4 returns to its original position;

[0021] The cleaning structure includes a connecting plate 5 fixedly connected to the mounting plate 1. A connecting block 6 is fixedly connected to the side wall of the connecting plate 5. A reciprocating screw 8 and a connecting shaft 13 are rotatably connected between the connecting blocks 6. A screw slider 10 is mechanically fitted on the reciprocating screw 8. A sliding block is sleeved on the connecting shaft 13. A rotating shaft 16 is rotatably connected between the sliding block and the screw slider 10. A cleaning plate 11 is fixedly sleeved on the rotating shaft 16. A cleaning brush 12 is fixedly installed on the cleaning plate 11. A motor 7 is fixedly installed on the connecting block 6. The motor 7 is a servo motor. After it starts, it will cause the reciprocating screw 8 to rotate until the screw slider 10 moves back and forth once, that is, the screw slider 10 finally moves back to its original position. The reciprocating screw 8 passes through the corresponding connecting block 6 and is fixedly connected to the output end of the motor 7. The connecting shaft 13 and the reciprocating screw 8 are connected by a belt drive assembly 9. A swing structure is installed on the connecting shaft 13.

[0022] After the motor 7 starts, its output end drives the reciprocating screw 8 to rotate. Since the screw slider 10 cannot rotate, the reciprocating screw 8 will cause the screw slider 10 to move back and forth when it rotates. When the screw slider 10 moves, it will drive the rotating shaft 16 to move together, causing the cleaning plate 11 fixedly sleeved on the rotating shaft 16 to move accordingly, driving the cleaning brush 12 to move and clean the surface of the embossed plate 4.

[0023] The swing structure includes a connecting cam 14 that is slidably sleeved on a connecting shaft 13. A connecting sleeve is fixedly installed on the side wall of the connecting cam 14, and the connecting sleeve is rotatably connected to the sliding block. A rotating shaft 16 passes through the sliding block and extends to the outside of the sliding block. An adjusting plate 15 is fixedly connected to the side wall of the rotating shaft 16. The adjusting plate 15 extends to the side of the connecting cam 14. A torsion spring 17 is fixedly connected between the adjusting plate 15 and the sliding block, and the torsion spring 17 is sleeved on the outside of the rotating shaft 16. The side wall of the adjusting plate 15 has rounded corners. The outer sides of both the adjusting plate 15 and the connecting cam 14 are fixedly covered with protective sleeves to protect the adjusting plate 15 and the connecting cam 14.

[0024] When the connecting shaft 13 rotates, the connecting cam 14, which is slidably sleeved on the connecting shaft 13, rotates accordingly. At the same time, under the action of the connecting sleeve, the connecting cam 14 and the sliding block move synchronously. When the connecting cam 14 rotates, it will squeeze the adjusting plate 15, thereby causing the adjusting plate 15 to deflect. At this time, the torsion spring 17 deforms. Then, as the connecting cam 14 rotates, the connecting cam 14 separates from the adjusting plate 15. The elastic force of the torsion spring 17 causes the adjusting plate 15 to return to its original position, thereby allowing the adjusting plate 15 to rotate back and forth. When the adjusting plate 15 rotates back and forth, it will drive the rotating shaft 16 to rotate back and forth as well, causing the cleaning plate 11 and the cleaning brush 12, which are fixedly sleeved on the rotating shaft 16, to rotate back and forth together, thereby improving the cleaning effect of the cleaning brush 12.

[0025] A fixing plate 2 is fixedly installed on the mounting plate 1, and the shape of the fixing plate 2 corresponds to the embossed plate 4. The embossed plate 4 has a groove that matches the fixing plate 2. Therefore, when the embossed plate 4 moves back, it will fit on the outside of the fixing plate 2. The fixing plate 2 supports and compresses the embossed plate 4 to maintain the shape of the embossed plate 4 and prevent it from deforming.

[0026] The mounting plate 1 is fixedly installed with a clip on its side wall. The mounting plate 1 is fixedly connected to the printing machine through the clip, which facilitates the installation of the mounting plate 1 and the entire embossing mechanism to the printing machine. The motor 7 is equipped with a control interface. After the printing machine and the motor 7 are fixedly connected together through the control interface via the control line, the motor 7 can be controlled on the operation panel of the printing machine.

[0027] In this invention, during use, the printing press drives the embossing rod 3 to move, thereby moving the embossing plate 4 together for embossing. After embossing is completed, the embossing plate 4 returns to its original position. After the embossing plate 4 returns to its original position, the motor 7 is started. After the motor 7 starts, its output end drives the reciprocating lead screw 8 to rotate. Since the lead screw slider 10 cannot rotate, the reciprocating lead screw 8 will cause the lead screw slider 10 to move back and forth when it rotates. When the lead screw slider 10 moves, it will drive the rotating shaft 16 to move together, causing the cleaning plate 11, which is fixedly sleeved on the rotating shaft 16, to move accordingly, driving the cleaning brush 12 to move and clean the surface of the embossing plate 4. At the same time, when the connecting shaft 13 rotates, the sliding sleeve on the connecting shaft 16 moves along with the cleaning plate 11. The connecting cam 14 on shaft 13 rotates accordingly. Simultaneously, under the action of the connecting sleeve, the connecting cam 14 and the sliding block move synchronously. When the connecting cam 14 rotates, it will squeeze the adjusting plate 15, causing the adjusting plate 15 to deflect. At this time, the torsion spring 17 deforms. Then, as the connecting cam 14 rotates, the connecting cam 14 separates from the adjusting plate 15. The elastic force of the torsion spring 17 causes the adjusting plate 15 to return to its original position, thus allowing the adjusting plate 15 to rotate back and forth. When the adjusting plate 15 rotates back and forth, it will drive the rotating shaft 16 to rotate back and forth as well, causing the cleaning plate 11 and the cleaning brush 12, which are fixedly sleeved on the rotating shaft 16, to rotate back and forth together, thereby improving the cleaning effect of the cleaning brush 12.
