[0030] Furthermore, a control box 205 is fixedly connected to the side of the motion block 204 , and the control box 205 is electrically connected to the rotating shaft 207 . A support ring 210 is rotatably connected to the bottom of the groove wheel 209 , and the support ring 210 is fixedly connected to the outer surface of the rotating shaft 207 .

[0031] Preferably, the electrical connection between the control box 205 and the rotating shaft 207 enables the lever 208 to have a power source when rotating, and the rotational connection between the support ring 210 and the groove wheel 209 can help the groove wheel 209 remain stable when rotating, indirectly improving the smoothing effect of the groove wheel 209 on the paper 105.

[0036] Specifically, a top of the support ring 210 is fixedly connected with a relaxation turntable 211 , and an outer surface of the relaxation turntable 211 is in intermittent contact with the paper 105 .

[0037] Furthermore, the stretching turntable 211 is connected to the top of the support ring 210 , so that when the paper 105 rotates with the paper roll 104 , the stretching turntable 211 also rotates relatively, which is beneficial to improving the flattening efficiency of the paper 105 and improving the flattening effect of the paper 105 .

[0038] Preferably, the side of the moving block 204 is fixedly connected to a straight spring 212, the end face of the straight spring 212 is fixedly connected to a stabilizing seat 213, the stabilizing seat 213 is slidably connected to the top of the straight groove 201 through a clamping strip at the bottom, and the top of the stabilizing seat 213 is fixedly connected to a leveling block 214 through a pin shaft.

[0039] Among them, the fixed connection of the straight spring 212 to the stable seat 213 allows the stable seat 213 to produce a linear displacement under the action of elastic force, and the sliding connection between the stable seat 213 and the straight groove 201 allows the smoothing block 214 to move, thereby smoothing and wrinkle-proofing the paper 105 for the second time, improving the product quality of the paper 105 and reducing cutting waste.

[0040] Afterwards, a guide roller 108 is provided on the lower surface of the paper 105, and a tension roller 106 is fixedly sleeved at the center of the guide roller 108.

The first stepper motor 107 is fixedly connected to a side plate 109 through a bracket, and the side plate 109 is plugged into the upper surface of the base 101.

[0041] In the above, the coordinated arrangement of the guide roller 108, the tension roller 106 and the first stepper motor 107 makes the paper 105 taut and straight, reducing the occurrence of wrinkles and scrapping of the paper 105. At the same time, the connection between the side panel 109 and the base 101 can help the first stepper motor 107 to remain relatively stable during operation.

[0042] When in use, first, the side panel 109 is plugged and fixed on the top of the base 101, and then the first stepper motor 107 and the side panel 109 are fixedly installed through the bracket, and then the guide roller 108 is sleeved on the outer side of the tension roller 106, and the first stepper motor 107 is fixedly connected to the end face of the tension roller 106. At the same time, the straight spring 212 is fixedly installed on the side of the moving block 204, and the stabilizing seat 213 is fixed to the end face of the straight spring 212. Then, a clamping strip is set on the top of the straight groove 201, and the stabilizing seat 213 is slidably connected to the clamping strip. The leveling block 214 is rotatably connected to the top of the stabilizing seat 213, which is used for secondary leveling of the leveling block 214.

[0043] In summary, by connecting the relaxation turntable 211 with the top of the support ring 210, when the paper 105 rotates with the paper roll 104, the relaxation turntable 211 also rotates relatively, which is beneficial to improving the smoothing efficiency of the paper 105 and improving the smoothing effect of the paper 105; the fixed connection of the straight spring 212 to the stable seat 213 allows the stable seat 213 to produce a linear displacement under the action of the elastic force, and the sliding connection between the stable seat 213 and the straight groove 201 allows the smoothing block 214 to move, thereby smoothing and wrinkle-resistant the paper 105 for the second time, improving the product quality of the paper 105, and reducing cutting waste.

[0047] Furthermore, the rotation of the ink supply roller 301 and the ink cartridge 302 allows the ink to be quickly supplied to the paper 105, helping to achieve the best inkjet effect on the paper 105, which is beneficial to improving the product quality of the paper 105.

[0049] Among them, the fixed installation of the winding roller 501 and the second stepper motor 502 allows the winding roller 501 to rotate synchronously when the second stepper motor 502 is running, thereby improving the winding efficiency of the paper 501. The setting of the waste paper slot 503 can collect waste products to avoid affecting the normal production of paper 501.
