[0024] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0025] Please refer to Figure 1 Figure 1 , the printing press 100 includes: A printing press 100 is provided, comprising a first frame 10, a printing reel 20, a first dust removal device 30, a second frame 40, and a second dust removal device 50. The printing reel 20 is disposed on the second frame 40 and is used to carry a material roll. The first dust removal device 30 is disposed on the first frame 10 and is used to remove dust from the first surface of the material roll. The second dust removal device 50 is disposed on the second frame 40. The second dust removal device 30 is located above the printing reel 20 and is used to remove dust from the second surface of the material roll. The material roll extends from an external unwinding mechanism through the first dust removal device 30 and contacts the first dust removal device 30. After the first dust removal device 30 rotates to complete the dust removal of the first surface, it extends from the surface of the First dust removal device 30 to the printing reel 20. Through the rotation of the printing reel 20, the second dust removal device 50 removes dust from the second surface of the material roll. The material roll extends from an external unwinding mechanism to the first dust removal device 30. When the first dust removal device 30 rotates and drives the first surface of the material roll to pass through the first dust removal device 30, the first dust removal device 30 starts and removes foreign objects and dust on its surface. As the material roll continues to rotate, its second surface gradually covers and passes through the second dust removal device 50. At this time, the second dust removal device 50 starts and removes foreign objects and dust on the second surface. In the above manner, the printing press 100 can keep the surface of the material roll clean during the entire printing process, thereby reducing the probability of screen damage and the risk of foreign objects in printed electrodes.

[0026] Please refer to Figure 2 and Figure 3, the first dust removal device 30 includes a first dust removal roller shaft 301 and a second dust removal roller shaft 302. The first dust removal roller shaft 301 and the second dust removal roller shaft 302 are arranged in parallel, and the material roll contacts the surface of the first dust removal roller shaft 301. The first dust removal roller shaft 301 is used for removing dust from the first surface of the material roll, and the second dust removal roller shaft 302 is used for the first dust removal roller shaft 301 to remove dust. The first dust removal roller shaft 301 is provided with a first adhesive film (not shown in the figure), and the second dust removal roller shaft 302 is provided with a second adhesive film (not shown in the figure). When the external unwinding mechanism of the material roll extends through the first dust removal device 30, the first surface of the material roll first passes through the first dust removal roller shaft 301 and contacts the first dust removal roller shaft 301. Further, the first adhesive film on the first dust removal roller shaft 301 contacts the first surface of the material roll. As the unwinding mechanism rotates, the first surface of the material roll contacts the first dust removal roller shaft 301, and the second dust removal roller shaft 302 contacts the first dust removal roller shaft 301. The two dust removal roller shafts rotate at an appropriate speed to remove dust and foreign objects from the material roll. Through the combined action of the two roller shafts, comprehensive dust removal of the first surface of the material roll is achieved, and at the same time, the first dust removal roller shaft 302 is dusted, ensuring that the material roll remains clean during transmission and reducing the risk of foreign objects during the printing process. The dust and foreign objects are removed from the material roll by the viscosity of the first adhesive film. As the material roll continues to rotate, the second dust removal device 50 is started simultaneously.

[0027] Specifically, please continue to refer to Figure 2 and Figure 3, the first rack 10 includes a first frame body 101 and a support frame 102. The first frame body 101 is connected to the support frame 102, and the first dust removal device 30 is rotatably arranged on the first frame body 101. The first frame body 101 includes a first fixed side plate 121 and a second fixed side plate 122. The first fixed side plate 121 and the second fixed side plate 122 are oppositely arranged on the support frame 102.

One end of the first dust removal roller shaft 301 is provided with a first rotating shaft 303, and the other end of the first dust removal roller shaft 301 is provided with a second rotating shaft 304. One end of the second dust removal roller shaft 302 is provided with a third rotating shaft (not shown in the figure), and the other end of the second dust removal roller shaft 302 is provided with a fourth rotating shaft 512. The first rotating shaft 303 is arranged in the first sliding groove 123, the second rotating shaft 304 is arranged in the third sliding groove 413, the third rotating shaft (not shown in the figure) is arranged in the second sliding groove 124, and the fourth rotating shaft 512 is arranged in the fourth sliding groove 414. By adjusting the positions of the first rotating shaft 303, the second rotating shaft 304, the third rotating shaft 5 (not shown in the figure) and the fourth rotating shaft 512 in the first sliding groove 123, the second sliding groove 124, the fourth sliding groove 414, the third sliding groove 413 and the fourth sliding groove 414, the position adjustment of the first dust removal roller shaft 301 and the second dust removal roller shaft 302 can be realized to meet the dust removal requirements of material coils with different sizes and positions.

[0028] Please refer to Figure 2 and Figure 3, the second dust removal device 50 includes a third dust removal roller shaft 501 and a fourth dust removal roller shaft 502. The fourth dust removal roller shaft 502 is disposed above the printing roller shaft 20, and the third dust removal roller shaft 501 is disposed above the fourth dust removal roller shaft 502. The fourth dust removal roller shaft 502 is used for removing dust from the second surface of the supply roll, and the third dust removal roller shaft 501 is used for removing dust from the fourth dust removal roller shaft 502. The third dust removal roller shaft 501 is provided with a third adhesive film (not shown in the figure), and the fourth dust removal roller shaft 502 is provided with a fourth adhesive film (not shown in the figure). When the supply roll rotates through the first dust removal device 30, the first surface of the supply roll first passes through the first dust removal roller shaft 301. The first adhesive film on the first dust removal roller shaft 301 contacts the surface of the supply roll, and dust and foreign matters are removed from the supply roll through the adhesiveness of the first adhesive film. When the supply roll rotates on the first dust removal device 30 and the dust removal of the first surface is completed, the supply roll naturally extends from the surface of the first dust removal roller shaft 301 to the second dust removal device 50. At this time, the supply roll covers the printing roller shaft 20, and the second surface of the supply roll contacts the fourth dust removal roller shaft 502. As the supply roll continues to rotate, the fourth adhesive film further removes dust and foreign matters on the second surface of the supply roll, and the third adhesive film removes dust and foreign matters attached to the fourth dust removal roller shaft 502. During long-term continuous operation, the second dust removal device 50 and the first dust removal device 30 always maintain a clean and efficient working state, thereby ensuring the cleanliness of the surface of the supply roll.

[0029] Please refer to Figure 3 , the second frame 40 includes a third frame body 401 and a fourth frame body 402. The third frame body 401 is connected to the fourth frame body 402. The printing roller shaft 20 is rotatably disposed on the third frame body 401, and the second dust removal device 50 is rotatably disposed on the fourth frame body 402. The fourth frame body 402 includes a third fixed side plate 411 and a fourth fixed side plate 412.

The third fixed side plate 411 is provided with a fifth sliding groove 415, and the fourth fixed side plate 412 is provided with a sixth sliding groove 416. One end of the second dust removal device 50 is provided with a fifth rotating shaft 521, and the other end of the second dust removal device 50 is provided with a sixth rotating shaft 522. The fifth rotating shaft 521 is disposed in the fifth sliding groove 415, and the sixth rotating shaft 522 is disposed in the sixth sliding groove 416. Through the above settings, the first dust removal device 30 rotates, and at the same time, the adhesiveness of the second dust removal device 50 is used to continuously clean the supply roll, so as to reduce foreign matters, reduce the probability of screen plate breakage and printing electrode foreign matters.

[0030] In some embodiments, the first dust removal device 30 is provided with an adjusting mechanism for adjusting the distance between the first dust removal roller shaft 301 and the second dust removal roller shaft 302 to adapt to coils of different sizes. This can ensure that an appropriate contact pressure is maintained between the dust removal roller shaft and the surface of the coil, improving the dust removal effect.

[0031] Please refer to Figure 1 and Figure 4 , the printing machine 100 further includes a height adjusting device 60 provided on the first frame 10. The height adjusting device 60 is used to adjust the height of the first dust removal device 30 to meet the dust removal requirements of coils of different sizes and positions.

The first fixing member sequentially passes through the first fixing hole 611 and the first fixing groove 131, and the second fixing member sequentially passes through the second fixing hole 612 and the second fixing groove 142. When it is necessary to adjust the height of the first dust removal device 30, first loosen the first fixing member and the second fixing member to enable the first height adjusting plate 601 and the second height adjusting plate 602 to move freely within a certain range. According to the size and position of the coil, adjust the heights of the first height adjusting plate 601 and the second height adjusting plate 602 respectively to ensure an appropriate distance and angle are maintained between the first dust removal device 30 and the coil.

[0032] After the adjustment is completed, tighten the first fixing member and the second fixing member to fix the first height adjusting plate 601 and the second height adjusting plate 602 at the new height position, thereby achieving precise adjustment of the height of the first dust removal device 30.
