The top of the printing table 1 is fixedly connected to the mounting base 101 by welding. The mounting frame 2 is installed on the rear side of the mounting base 101 by bolt connection. The first cylinder 3 is installed on the mounting frame 2 by bolt connection. The first guide rod 4 is fixedly connected to the rear side of the mounting base 101. Two guide frames 6 are installed on the right side of the inner wall of the mounting base 101. The connecting frame 601 is slidably arranged on both of the two guide frames 6, and the connecting frame 601 slides up and down in the guide frame 6. The left ends of the two connecting frames 601 are jointly installed with the second cylinder 602. The right ends of the two connecting frames 601 are jointly installed with the printing screen frame 5. The output end of the printing screen frame 5 is installed with the squeegee 603, and the squeegee 603 slides on the printing screen frame 5. Two connecting plates 501 are installed on one side of the rear side of the printing screen frame 5. The connecting plates 501 are slidably connected to the mounting base 101.

At this time, the rack 13 meshes with the one-way gear 1301, and the rack 13 drives the one-way gear 1301 to rotate, so as to automatically wind the printed reflective substrate, and at the same time make the unprinted reflective substrate located below the printing screen frame 5, realizing automatic feeding of the reflective substrate, without manual operation, and improving the safety during printing.

[0028] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 and Figure 8 as shown, it further includes an upper mounting housing 14, a lower mounting housing 15, a blower 16 and a heating pipe 17. The upper mounting housing 14 is installed on the right side of the mounting seat 101 by means of bolt connection. The lower mounting housing 15 is installed below the upper mounting housing 14. Two ventilation grooves are opened at the top of the upper mounting housing 14. Four blowers 16 are installed inside the lower mounting housing 15 by means of bolt connection. The heating pipe 17 is installed in the upper part of the upper mounting housing 14. The heating pipe 17 is located above the blower 16. The isolation net 25 is installed at the top of the upper mounting housing 14 by means of bolt connection. The isolation net 25 covers the two ventilation grooves on the upper mounting housing 14 to prevent foreign objects from being sucked into the inside of the upper mounting housing 14 and causing the blower 16 to malfunction.

[0029] When printing, the blower 16 and the heating pipe 17 are started. The heating pipe 17 generates heat to heat the surrounding air, and the blower 16 blows out the hot air. When the roll shaft 9 winds the reflective substrate, the blower 16 blows the hot air on the reflective substrate, so as to dry the moisture in the glue on the reflective substrate and accelerate the drying of the reflective substrate. After printing, the blower 16 and the heating pipe 17 are turned off.

[0030] Refer to Figure 2 and Figure 9 As shown, it further includes a positioning frame 18, a second guide rod 19, a punch 20, an elastic member 21, a connecting seat 22, a pressing plate 23 and a torsion spring 24. The left side inside the mounting seat 101 is installed with the positioning frame 18 by means of bolt connection. Two second guide rods 19 are slidably arranged on the positioning frame 18. The lower ends of the two second guide rods 19 are jointly installed with the punch 20. The punch 20 is composed of a horizontal plate and multiple punching needles. The lower ends of the two second guide rods 19 are jointly installed with a horizontal plate, and multiple punching needles are fixedly connected to the bottom of the horizontal plate. An elastic member 21 is connected between the second guide rod 19 and the positioning frame 18. The elastic member 21 is sleeved on the second guide rod 19. The top of the punch 20 is fixedly connected with the connecting seat 22. A pressing plate 23 is rotatably arranged on the connecting seat 22. Two torsion springs 24 are connected between the pressing plate 23 and the connecting seat 22. The torsion springs 24 are sleeved on the connecting shaft of the pressing plate 23. The printing screen frame 5 slides down to squeeze the pressing plate 23 to rotate, and a protective sleeve 26 is slidably arranged at the lower part of the punch 20

[0031] When the telescopic rod of the first cylinder 3 drives the printing screen frame 5 to move downward, the printing screen frame 5 squeezes the pressing plate 23. The pressing plate 23 drives the punch 20 and the second guide rod 19 to slide downward. The second guide rod 19 squeezes the elastic member 21 to deform. When the punch 20 and the second guide rod 19 slide downward to contact the reflective substrate, the punch 20 punches the reflective substrate, which is convenient for subsequent segmented cutting of the reflective substrate. At this time, the telescopic rod of the first cylinder 3 continues to drive the printing screen frame 5 to move downward. The printing screen frame 5 squeezes the pressing plate 23 to turn downward. The pressing plate 23 drives the torsion spring 24 to deform. When the printing screen frame 5 passes over the pressing plate 23, the torsion spring 24 returns to its original state and drives the pressing plate 23 to turn upward and reset. At the same time, the elastic member 21 returns to its original state and drives the second guide rod 19 and the punch 20 to slide upward and reset.
