Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, a cultural and creative printing device includes: a conveying device 1, a lifting device 2, a pressing device 3, and a reduction gearbox 4; the lifting device 2 is arranged above the conveying device 1; the pressing device 3 is arranged on the lifting device 2; the lifting device 2 drives the pressing device 3 to rise and fall; the reduction gearbox 4 is rotatably connected to the outside of the conveying device 1; the reduction gearbox 4 is rotatably connected to a rotating handle 5, and the rotating handle 5 drives the conveying device 1 to rotate by rotating.

[0025] In use, the handle 5 is a hand crank; turning the handle 5 drives the reduction gearbox 4, and the conveying device 1 moves the printing plate toward the pressing device 3; the lifting device 2 is manually adjusted to drive the pressing device 3 to lift and clamp the printing plate, print, etc.; so that the printing plate moves slowly and stably on the conveying device 1; the reduction gearbox 4 can better slow down the speed, so that the printing plate passes through the printing machine smoothly and the printing color is uniform.

[0026] In one exemplary embodiment, such as Figure 2 As shown, the reduction gearbox 4 includes a housing 41, a first gear 42, and a second gear 43. The housing 41 has a two-stage stepped structure in cross-section, with the stepped structure facing upwards. The housing 41 is fixedly connected to the outside of the conveying device 1, and the upper surface of the first step of the housing 41 is flush with the upper surface of the conveying device 1. The first gear 42 and the second gear 43 are rotatably connected inside the housing 41. The rotating handle 5 passes through the surface of the housing 41 facing the opposite direction to the conveying device 1 and is rotatably connected to the first gear 42. The second gear 43 passes through the surface of the housing 41 facing the conveying device 1 and is rotatably connected to the conveying device 1. The first gear 42 and the second gear 43 mesh, and the second gear 43 is larger than the first gear 42.

[0027] Specifically, the function of the reduction gearbox 4 is to reduce speed; the small gear drives the large gear to rotate, which can achieve the effect of speed reduction.

[0028] In one exemplary embodiment, such as Figure 1As shown, the conveying device 1 includes a rectangular frame 101, a drive roller 102, and driven rollers 103. Multiple driven rollers 103 are arranged parallel to the drive roller 102 along the output and input directions of the conveying device 1. The driven rollers 103 are rotatably connected to the rectangular frame 101 and the drive roller 102. The top edges of the drive roller 102 and the multiple driven rollers 103 are all on the same plane. One end of the drive roller 102 passes through the rectangular frame 101 and is connected to the second gear 43. The lifting device 2 is fixedly connected above the rectangular frame 101. The pressing device 3 is located above the drive roller 102 and is parallel to the drive roller 102. Specifically, the drive roller 102 drives the printing plate to move slowly, and the movement of the printing plate drives the driven rollers 103 to move, reducing friction.

[0029] In one exemplary embodiment, such as Figure 1 As shown, the lifting device 2 is a hand-cranked fine-tuning screw slide; there are two hand-cranked fine-tuning screw slides; the hand-cranked fine-tuning screw slides are arranged opposite to each other and parallel to each other; the pressing device 3 is fixedly connected to the sliders of the two hand-cranked fine-tuning screw slides.

[0030] Specifically, the hand-cranked fine-tuning screw slide is made of aluminum alloy, which is relatively light. The hand-cranked fine-tuning screw slide moves slowly, which can drive the pressing device 3 to slowly press the printing plate, print, etc. When in use, the two hand-cranked fine-tuning screw slides need to be adjusted at the same time to keep them parallel to the transmission roller 102.

[0031] In one exemplary embodiment, such as Figure 1 As shown, the pressing device 3 includes a movable block 31 and a pressure roller 32; two movable blocks 31 are provided, and the pressure roller 32 is fixedly connected between the two movable blocks 31; the movable blocks 31 are fixedly connected to the slider of the hand-cranked fine-tuning screw slide table; the pressure roller 32 is located above the transmission roller 102; the pressure roller 32 and the transmission roller 102 are parallel. Specifically, the slider of the hand-cranked fine-tuning screw slide table, the base, and the first rectangular body 104 are all on the same plane facing the transmission roller 102; the pressure roller 32 rises and falls to press the relief plate or print.

[0032] In one exemplary embodiment, such as Figure 1As shown, the rectangular frame 101 includes a first rectangular body 104 and a second rectangular body 105; two first rectangular bodies 104 and two second rectangular bodies 105 are respectively provided; the two ends of the first rectangular body 104 are fixedly connected to the second rectangular body 105, and the second rectangular body 105 is perpendicular to the first rectangular body 104; the second rectangular body 105 is lower than the first rectangular body 104; the upper surface of the second rectangular body 105 and the top of the transmission roller 102 are on the same plane; the second rectangular body 105 and the transmission roller 102 are parallel; the two first rectangular bodies The drive roller 102 and the driven roller 103 are rotatably connected between 104; the drive roller 102 is located in the middle of the first rectangular body 104; any end of the drive roller 102 passes through any of the first rectangular bodies 104 and the vertical surface of the first step of the housing 41 and is connected to the second gear 43; the vertical surface of the first step of the housing 41 is fixedly connected to the first rectangular body 104; the upper surface of the first step of the housing 41 is flush with the upper surface of the first rectangular body 104; the upper surface of the first rectangular body 104 is fixedly connected to the hand-cranked fine-tuning screw slide.

[0033] Specifically, the second rectangular body 105, the drive roller 102, and the driven roller 103 are parallel; the upper surface of the second rectangular body 105 is lower than the first rectangular body 104; the lower surface of the second rectangular body 105 and the lower surface of the first rectangular body 104 are on the same plane; when in use, the width of the printed plate is less than the distance between the two first rectangular bodies 104, which allows the printed plate to be better adjusted when placed on the conveyor device 1; a sliding device can also be provided on the first rectangular body 104 to allow the printed plate to pass through better.

[0034] In one exemplary embodiment, such as Figure 3-4 As shown, a plurality of bearings 6 are rotatably connected inside the first rectangular body 104; a plurality of through holes 106 are opened on the surface of the first rectangular body 104 facing the transmission roller 102, and the through holes 106 are located above the top of the transmission roller 102; the outer ring of the bearing 6 protrudes from the surface of the first rectangular body 104 through the through holes 106.

[0035] In this invention, the inner ring of the bearing 6 is fixedly connected inside the first rectangular body 104, and the outer ring of the bearing 6 rotates relative to it. The rotation of the transmission roller 102 drives the printing plate to move, which will cause the printing plate to tilt. The bearings 6 on both sides can rotate and contact the sides of the printing plate, which can reduce friction and limit the position.

[0036] In one exemplary embodiment, such as Figure 1As shown, the slider, base, and surface of the first rectangular body 104 of the hand-cranked fine-tuning screw slide are flush with the surface of the transmission roller 102; the lower surface of the movable block 31 is lowered to be flush with the upper surface of the first rectangular body 104; the bottom of the pressure roller 32 is lower than the lower surface of the movable block 31; and the bottom of the pressure roller 32 is close to the top of the transmission roller 102.

[0037] In this invention, the slider moves downward, causing the movable block 31 to descend into the rectangular frame 101; this, in turn, causes the pressure roller 32 to come into close contact with the transmission roller 102, reducing the distance between the transmission roller 102 and the pressure roller 32. In the prior art, when the pressure roller descends to its lowest point, it cannot come into close contact with the transmission roller, resulting in incomplete printing when printing paper prints. This invention can perform not only relief printing but also print printing, making it widely applicable.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
