[0036] like Figure 1-Figure 2 As shown, the present application provides a decorative paper printing feeding roller assembly, comprising a base 1, two sets of support frames 11 are fixedly installed on the upper end of the base 1, and mounting plates 12 are fixedly installed on opposite sides of the two sets of support frames 11, and a reeling roller 13 is rotatably connected between the upper ends of the mounting plates 12, and the reeling roller 13 is used to reel the decorative paper to be printed;

[0037] At the same time, a loading roller 15 is rotatably connected between the lower ends of the mounting plates 12, and a printing mechanism (not shown) is provided on one side of the mounting plate 12 close to the loading roller 15, and the decorative paper is transmitted to the printing mechanism through the loading roller 15. In the present application, the decorative paper first passes through the unwinding roller 13 and then is wound around the loading roller 15, which is not shown in detail here, and a driving mechanism (not shown) is provided on one side of the unwinding roller 13 and the loading roller 15, and the driving mechanism is a driving motor in the prior art, which drives the unwinding roller 13 and the loading roller 15 to rotate through the driving motor.

[0038] like Figure 2-Figure 4 As shown, in order to heat the decorative paper to be printed, a heating roller 2 is further arranged between the mounting plates 12, a through heat dissipation cavity is provided inside the heating roller 2, and heat dissipation holes are provided on the heating roller 2, and connecting shafts 21 are fixedly installed at both ends of the heating roller 2, and the connecting shafts 21 are rotatably connected to the mounting plate 12. In the present application, the heating roller 2 is arranged between the unwinding roller 13 and the feeding roller 15, and the decorative paper bypasses the heating roller 2, so that the decorative paper is heated;

[0039] A hot air blower 22 is fixedly mounted on the upper end of the support frame 11. The hot air blower 22 is used to deliver hot air to the heating roller 2. A heating pipe 23 is arranged on the hot air blower 22. The heating pipe 23 penetrates the mounting plate 12 until it is connected to the heating roller 2, thereby providing heat to the heating roller 2. In the present application, a rotating joint (not shown) is installed at one end of the heating roller 2 facing the heating pipe 23. The rotating end of the rotating joint is mounted on the heating roller 2, and the fixed end of the rotating joint is mounted on the heating pipe 23. Therefore, the heating roller 2 will not contact the heating pipe 23 when it rotates, so that the heating pipe 23 can provide heat normally.

[0040] In order to facilitate the adjustment of the air output of the heating roller 2, a shielding roller 24 is provided on the inner side of the heating roller 2, and the shielding roller 24 is rotatably connected to the connecting shaft 21. At the same time, a baffle 25 is fixed on the shielding roller 24, and the baffle 25 is attached to the inner wall of the heating roller 2. The baffle 25 corresponds to the heat dissipation holes on the heating roller 2, so that the heat dissipation holes can be blocked by adjusting the position of the baffle 25.

[0041] An adjustment mechanism 3 is provided on the outer side of the mounting plate 12. The adjustment mechanism 3 has a mounting groove 38 provided on the mounting plate 12. The connecting shaft 21 is placed in the mounting groove 38. A ring (not shown) is sleeved between the mounting groove 38 and the connecting shaft 21. The ring is rotatably connected in the mounting groove 38 and fixed to the connecting shaft 21. The ring is used to support the connecting shaft 21 in the mounting groove 38.

[0042] A fixing rod 32 is fixedly installed at one end of the shielding roller 24 close to the mounting groove 38. The fixing rod 32 passes through the mounting groove 38 and is fixed on the ring. Therefore, when the heating roller 2 and the shielding roller 24 rotate, the fixing rod 32 and the ring will be driven to rotate in the mounting groove 38.

[0043] At the same time, an extension rod (not shown in the figure) is fixed on the outer side of the connecting shaft 21, and a fixing plate 33 is fixedly installed on the extension rod. At the same time, a convex plate 31 is fixedly installed at the axis center of the fixing plate 33. A gap is left between the convex plate 31 and the fixing plate 33, and the other end of the convex plate 31 protrudes from the fixing plate 33. In the present application, one end of the fixing rod 32 away from the shielding roller 24 is fixedly installed on the protruding end of the convex plate 31. Therefore, when the fixing rod 32 rotates with the shielding roller 24, it will drive the convex plate 31 to perform a circular motion along the center of the fixing plate 33.

[0044] In order to facilitate the adjustment of the position of the baffle 25 on the shielding roller 24, a matching hole 36 is opened on the convex plate 31, and a plurality of groups of fixing holes 35 are opened on the fixing plate 33. The plurality of fixing holes 35 are arranged in an arc shape with the center of the fixing plate 33. The fixing holes 35 and the matching holes 36 correspond to each other, and a clamping column 37 is installed in the matching hole 36 and one of the groups of fixing holes 35. Therefore, after the clamping column 37 is inserted into the matching hole 36 and the fixing hole 35, the fixing plate 33 is fixed to fix the shielding roller 24.

[0045] In summary: when it is necessary to heat the decorative paper to be printed, the hot air blower 22 is started to allow the hot air to enter the heating roller 2 through the heating pipe 23 and blow outward through the heat dissipation holes on the heating roller 2, thereby heating the decorative paper transmitted to the heating roller 2;

[0046] If the air volume of the heating roller 2 needs to be adjusted, the clamping column 37 is pulled out, and the convex plate 31 and the fixing rod 32 are manually rotated through the handle 34, and the shielding roller 24 is driven to rotate at the same time. At this time, the matching position of the baffle 25 and the heat dissipation hole is observed. When the baffle 25 blocks the heat dissipation hole to half, the clamping column 37 is inserted into the matching hole 36 and the corresponding fixing hole 35 at this time, so as to fix the shielding roller 24, thereby adjusting the air volume of the heating roller 2. Therefore, the decorative paper to be printed is heated to prevent excessive moisture from affecting the ink absorption rate, thereby improving the printing quality, and the decorative paper can also be made smoother by heating, reducing the curling and warping of the paper, which is beneficial to the stability and precision during printing.

[0047] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
