[0043] Reference Figure 2 and Figure 3 A first mounting seat 9 and a second mounting seat 10 are provided on both sides of the mounting frame 2. There are two first mounting seats 9 and two second mounting seats 10, with the two first mounting seats 9 located on the side of the mounting frame 2 away from the vertical conveying device 35, and the two second mounting seats 10 located on the side of the mounting frame 2 closer to the vertical conveying device 35. A cylindrical rotating shaft 16 is integrally formed on the surface of the first mounting seat 9 facing the mounting frame 2. The rotating shaft 16 is perpendicular to the first rubber roller 301. A rotating groove 17 is provided on the mounting frame 2, and the rotating shaft 16 rotates in conjunction with the rotating groove 17. The second mounting seat 10 is fixed to the mounting frame 2 with bolts. The rotation of the rotating shaft 16 and the rotating groove 17 enable the first mounting seat 9 to rotate on the mounting frame 2, facilitating the rotation of the first rubber roller 301 or the third rubber roller 303 to one side of the mounting frame 2.

[0044] Reference Figure 2 and Figure 3 An arc block 18 is integrally formed on the circumferential surface of the rotating shaft 16, and an arc groove 19 is formed on the groove wall of the rotating groove 17. The arc of the arc groove 19 is greater than that of the arc block 18. Specifically, when the arc of the arc groove 19 is semicircular, the arc of the arc block 18 is quarter-circular. That is, the arc block 18 can rotate 90 degrees within the arc groove 19. By rotating the first rubber roller 301 so that the first rubber roller 301 and the second rubber roller 302 are parallel to each other, the first rubber roller 301 and the second rubber roller 302 are perpendicular to each other, or by rotating the third rubber roller 303 so that the third rubber roller 303 and the second rubber roller 302 are parallel to each other, the third rubber roller 303 and the second rubber roller 302 are perpendicular to each other. The arc block 18 cooperates with the arc groove 19 to limit the rotation angle of the first mounting seat 9.

[0045] Reference Figure 2 and Figure 3 The ends of the first rubber roller 301 are located between a first mounting seat 9 and a second mounting seat 10, while the ends of the third rubber roller 303 are located between another set of first mounting seats 9 and second mounting seats 10. Both the first rubber roller 301 and the third rubber roller 303 include a connecting rod 6 and a dust removal rubber cartridge 7, which is sleeved onto the outside of the connecting rod 6. The first mounting seat 9 defines a first insertion slot 91 for inserting one end of the connecting rod 6. The second mounting seat 10 defines a second insertion slot 101 for inserting the other end of the connecting rod 6. The first insertion slot 91 is deeper than the second insertion slot 101.

[0046] Reference Figure 2 and Figure 3 An abutment block 11 is slidably connected in the first insertion slot 91. A pressure spring 12 is installed in the first insertion slot 91. One end of the pressure spring 12 is fixedly connected to the slot wall of the first insertion slot 91, and the other end of the pressure spring 12 is fixedly connected to the abutment block 11. In this embodiment, the connecting rod 6 is pushed toward the first mounting seat 9 so that the other end of the connecting rod 6 is separated from the second insertion slot 101, making it easy to remove the connecting rod 6 from the first mounting seat 9 and the second mounting seat 10, thereby facilitating the replacement of the dust removal rubber cylinder 7; when the other end of the connecting rod 6 is aligned with the second insertion slot 101, the pressure spring 12 pushes the abutment block 11 and the connecting rod 6 to move, allowing the other end of the connecting rod 6 to be inserted into the second insertion slot 101, thereby fixing the first rubber roller 301 or the third rubber roller 303 on the mounting frame 2.

[0047] Reference Figure 3 and Figure 4A circular groove 13 is formed on the wall of the first insertion groove 91. A rotating block 14 is integrally formed on the end of the connecting rod 6 near the first mounting seat 9. The rotating block 14 engages with the circular groove 13. A sliding groove 15 is formed on the side of the first mounting seat 9. The sliding groove 15 is connected to the first insertion groove 91 and the circular groove 13 respectively. That is, the sliding groove 15 allows the rotating block 14 to be inserted into the circular groove 13 and rotate within the circular groove 13. In this embodiment, the rotation block 14 and the circular groove 13 are aligned to prevent one end of the connecting rod 6 from falling off the first mounting seat 9. The pressure spring 12 cooperates with the abutment block 11 to press the rotating block 14 against the wall of the circular groove 13, further preventing one end of the connecting rod 6 from falling off the first mounting seat 9. When the connecting rod 6 needs to be removed, the connecting rod 6 is rotated so that the rotating block 14 is aligned with the sliding groove 15, making it easier to pull one end of the connecting rod 6 out of the first mounting seat 9.

[0048] Reference Figure 3 and Figure 4 A limiting assembly 8 is installed on the connecting rod 6, which can limit the position of the dust removal rubber cylinder 7. The limiting assembly 8 includes a positioning ring 81 and a positioning block 82. The positioning ring 81 is fixed to the connecting rod 6 by welding and is located at the end of the connecting rod 6 near the first mounting seat 9. A recessed groove 83 is formed on the connecting rod 6 and is located at the end of the connecting rod 6 near the second mounting seat 10. The positioning block 82 is slidably connected to the recessed groove 83. A return spring 84 is installed in the recessed groove 83. One end of the return spring 84 is fixed to the bottom of the recessed groove 83, and the other end of the return spring 84 is fixed to the positioning block 82. In other words, the positioning ring 81 abuts against one end face of the dust removal rubber cylinder 7, and the positioning block 82 abuts against the other end face of the dust removal rubber cylinder 7.

[0049] It should be noted that the two ends of the dust removal rubber cylinder 7 are respectively abutted by the positioning ring 81 and the positioning block 82, thereby limiting the position of the dust removal rubber cylinder 7 on the connecting rod 6, and the dust removal rubber cylinder 7 can rotate on the connecting rod 6, so that the dust removal rubber cylinder 7 has a better cleaning effect on the surface of the printed part; when the dust removal rubber cylinder 7 needs to be replaced, press the positioning block 82 so that the positioning block 82 is located in the recessed groove 83, and the dust removal rubber cylinder 7 can be pulled out from the end of the connecting rod 6 close to the positioning block 82.

The two mounting bars 44 are located between the second rubber roller 302 and the third rubber roller 303, and the two connecting bars 45 are located on the side of the mounting frame 2 away from the printing table 1. There are four support rollers 4, three of which are rotatably connected between the two mounting bars 44, and the other support roller 4 is rotatably connected between the two connecting bars 45.

[0051] Reference Figure 2 and Figure 5 A limiting assembly 5 is installed on the support roller 4, and the limiting assembly 5 is used to limit the position of the workpiece to be printed. The limiting assembly 5 includes two limiting rings 51, both of which are slidably sleeved on the support roller 4; the limiting ring 51 is fixedly connected to a fixed cylinder 52 on the side close to the mounting frame 2, and a threaded rod 53 is threadedly connected to the fixed cylinder 52, which can abut against the surface of the support roller 4. In this embodiment, the fixed cylinder 52 is integrally formed on one side of the limiting ring 51. The two limiting rings 51 limit the two sides of the workpiece to be printed, which can reduce the possibility of damage to the two sides of the workpiece to be printed; by pushing the limiting ring 51, the distance between the two limiting rings 51 can be changed, so that the limiting assembly 5 is suitable for workpieces to be printed of different widths; the position of the fixing cylinder 52 on the support roller 4 is fixed by the threaded rod 53, thereby adjusting the position of the two limiting rings 51 on the support roller 4.

[0052] Reference Figure 5 and Figure 6 A round rod 20 is rotatably connected between the two mounting bars 44. The round rod 20 is positioned between the three support rollers 4 and the second rubber roller 302, and is parallel to the second rubber roller 302. The round rod 20 is covered with a dust-free cloth 21, which is provided with a plurality of evenly distributed suction holes 22. In this embodiment, the soft surface of the dust-free cloth 21 prevents scratches. As the printed workpiece moves, the dust-free cloth 21 absorbs foreign matter from the surface and firmly traps it in the suction holes 22, thus removing dust and preventing scratches caused by friction between the printed workpiece and the round rod 20.

[0053] Reference Figure 5 and Figure 6Both sides of the mounting frame 2 are provided with receiving slots 23 for the ends of the round rod 20.

[0054] It should be noted that the two ends of the round rod 20 are restricted in the receiving groove 23 by the covering block 24, so that the round rod 20 is rotatably connected to the mounting frame 2; by pushing the toggle block 29, the end of the fixing bar 26 is inserted into the fixing groove 27, so that the covering block 24 is fixed at the notch of the receiving groove 23, that is, the two ends of the round rod 20 are detachably connected to the mounting frame 2, which facilitates the cleaning and replacement of the dust-free cloth 21 on the round rod 20.

[0055] The implementation principle of the high-definition laminated hidden screen production equipment of the embodiment of the present application is as follows: the connecting rod 6 is pushed toward the first mounting seat 9, so that the other end of the connecting rod 6 is separated from the second plug-in slot 101; the connecting rod 6 is then pushed away from one end of the first mounting seat 9, so that the first mounting seat 9 can rotate on the mounting frame 2, facilitating the rotation of the first rubber roller 301 and the third rubber roller 303 to one side of the mounting frame 2. The workpiece to be printed is placed above the second rubber roller 302, the four support rollers 4, and the dust-free cloth 21, that is, the roll of the workpiece to be printed is moved over the support roller 4, the second rubber roller 302, the dust-free cloth 21, and the three support rollers 4 in sequence.

[0056] Finally, the connecting rod 6 is pushed in the opposite direction away from one end of the first mounting seat 9, so that the first and third rubber rollers 301 and 303 are respectively parallel to the second rubber roller 302, that is, the other end of the connecting rod 6 is aligned with the second insertion slot 101. The pressure spring 12 pushes the abutment block 11 and the connecting rod 6 to move, allowing the other end of the connecting rod 6 to be inserted into the second insertion slot 101, so that the first and third rubber rollers 301 and 303 are located on the upper surface of the workpiece to be printed. The first rubber roller 301, dust-free cloth 21, and third rubber roller 303 remove dust and other impurities from the upper surface of the workpiece to be printed, which is conducive to improving the printing quality of the workpiece to be printed. The second rubber roller 302 removes dust and other impurities from the lower surface of the workpiece to be printed, preventing the presence of dust and other impurities from causing unevenness on the upper surface of the workpiece to be printed, thereby improving the printing quality of the workpiece to be printed.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Unless otherwise specified, any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features. Therefore, any equivalent changes based on the structure, shape, and principle of this application shall be included in the scope of protection of this application.
