Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] To solve the problem that wrinkles are likely to occur on the surface of the paper after glue brushing, please refer to Figures 1-6 , a pressing device for printing of printed matter provided in this embodiment adjusts the horizontal position of the smoothing block 33 to move the smoothing block 33 on the surface of the paper, so that the wrinkles on the surface of the paper are smoothed during the movement of the smoothing block 33, thereby improving the subsequent pressing effect of the paper. The device includes a base 1, and the base is used to carry the smoothing component 3 and the pressing component 4. A protective shell 2 is fixedly connected to the base 1, and the protective shell 2 is used to protect its internal structure and avoid damage caused by the external environment. Inside the protective shell 2, there are a glue coating component 6 for applying glue, a smoothing component 3 for smoothing the wrinkles of the paper, and a pressing component 4 for pressing the paper. Pass two pieces of paper through the protective shell, make the glue coating component 6 located between the upper and lower surfaces of the paper, pass the paper under the smoothing component 3 and the pressing component 4, apply glue to the paper through the glue coating component 6, adjust the height of the smoothing component 3 to fit the surface of the paper to smooth the wrinkles on the paper, and press the paper through the pressing component 4, thereby improving the pressing effect of the paper.

[0031] The glue - applying assembly 6 includes a glue - applying roller 62 that rotates inside the protective shell 2. The glue - applying roller 62 is used to apply glue to the surface of the paper. The glue - applying roller 62 is arranged in front of the smoothing assembly 3. The end of the glue - applying roller 62 is fixedly connected to a third motor 61 installed on the protective shell 2, and the third motor 61 is used to drive the glue - applying roller 62 to rotate. The smoothing assembly 3 includes a hydraulic rod 31 fixed on the protective shell 2. The movable end of the hydraulic rod 31 is fixedly connected to a sliding plate 32 that slides inside the protective shell 2. The hydraulic rod 31 is used to drive the sliding plate 32 to adjust the height. The sliding plate 32 is slidably connected with symmetrically arranged L - shaped wiping blocks 33. The wiping blocks 33 are used to smooth the wrinkles on the surface of the paper. Inside the protective shell 2, there is a sliding assembly 5 that drives the two wiping blocks 33 to slide in opposite directions. The sliding assembly 5 is used to drive the two wiping blocks 33 to slide in opposite directions. The vertical end of the wiping block 33 is provided with a connecting groove 40 and the horizontal end is provided with a supporting groove 401. The connecting groove 40 is used for the wiping block 33 to connect to the pressing roller 44, and the supporting groove 401 is used to support the pressing roller 44. When pressing the paper, the front end of the paper passes through the protective shell 2, respectively passes through the upper and lower parts of the glue - applying roller 62, then the paper passes under the smoothing assembly 3 and the pressing assembly 4 and extends outside the protective shell 2, and the paper is wound into the coiler. Subsequently, the power supply is started. The third motor 61 starts to make the glue - applying roller 62 apply glue to the surface of a piece of paper. Driven by the coiler, the paper reaches below the smoothing assembly 3. The hydraulic rod 31 is started, and the movable end of the hydraulic rod 31 drives the sliding plate 32 to move downwards, so that the wiping blocks 33 move downwards to fit the surface of the paper. The sliding assembly 5 drives the wiping blocks 33 to slide relative to each other on the surface of the paper. During the sliding process, the surface of the paper is smoothed, reducing the influence of paper wrinkles on the subsequent pressing of the paper and improving the effect of the subsequent pressing of the paper.

[0032] Considering that the wiping block 33 needs to smooth the paper, refer to Figures 1-6 , therefore, the sliding assembly 5 includes symmetrically arranged support plates 54 that slide on the protective shell 2. The support plates 54 are used to carry the limiting rods 52, the bidirectional screw 51, and the second motor 53. The limiting rods 52 that penetrate the wiping blocks 33 are installed on the support plates 54. The bidirectional screw 51 that is rotationally installed on the support plates 54 and is threadedly connected to the wiping blocks 33. The end of the bidirectional screw 51 is fixedly connected to the second motor 53 installed on the support plates 54. The second motor 53 is used to drive the bidirectional screw 51 to rotate. By driving the bidirectional screw 51 to rotate with the second motor 53, under the action of the limiting rods 52, the wiping blocks 33 slide relative to each other on the bidirectional screw 51, thereby realizing the smoothing of the paper by the wiping blocks 33.

[0033] Considering that the paper needs to be pressed after the smoothing assembly 3 smooths the surface of the paper, refer to Figures 1-6, therefore, the pressing assembly 4 includes a spring 41 fixedly connected in the connection groove 40. The end of the spring 41 is fixedly connected with a connection block 42 slidably mounted on the connection groove 40. The end of the connection block 42 is fixedly connected with a folded connecting plate 43. The connection block 42 and the connecting plate 43 are used to connect the sliding plate 32 and the wiping block 33. A pressing roller 44 disposed in the support groove 401 is rotatably connected between the connecting plates 43. The pressing roller 44 is used to press the paper. A first motor 45 mounted in the protective shell 2 is fixedly connected to the pressing roller 44. The first motor 45 is used to drive the pressing roller 44 to rotate. When the wiping block 33 slides to the edge of the paper, the movable end of the hydraulic rod 31 drives the sliding plate 32 to move downward again, pushing the wiping block 33 below the edge of the paper. At this time, the pressing roller 44 disengages from the support groove 401 and falls onto the surface of the paper. Under the pressure of the spring 41 and the weight of the pressing roller 44 under the downward push of the hydraulic rod 31, the paper is pressed. The first motor 45 drives the pressing roller 44 to rotate to convey the pressed paper, thus completing the pressing of the paper.

[0034] Considering that when the paper after brushing glue is pressed by the pressing roller 44, glue will overflow from the edge. If it is not cleaned up, it will cause the paper to stick together, thus affecting the printing effect of the paper. Refer to Figures 1-6 , therefore, a cleaning assembly 35 for cleaning the glue overflowing from the edge of the paper is provided on one side of the lower end of the wiping block 33. The cleaning assembly 35 includes a scraping plate 351. The cross-section of the scraping plate 351 is in the shape of a parallelogram. The cross-section of the parallelogram is used to scrape the glue at the glue overflowing place on the edge of the paper. The other end of the scraping plate 351 is fixedly connected with a collecting groove 353. The collecting groove 353 is used to collect the glue scraped by the scraping plate 351. The surface of the collecting groove 353 is set as an inclined section. The cross-section is used to make the glue drip onto the cross-section after being scraped and then slide into the collecting groove 353. When the pressing roller 44 presses the paper, since the wiping block 33 has been adjusted to the edge of the paper, during the process of pressing and pulling the paper, the cross-section of the scraping plate 351 in the shape of a parallelogram is used to scrape the overflowing glue, thereby improving the pressing effect of the subsequent paper. The scraped glue slides into the collecting groove 353, which is convenient for personnel to collect and clean the glue.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, considering that the scraping plate 351 needs to be replaced or cleaned after scraping the glue to improve the use effect of scraping the glue next time. Refer to Figures 1-6, therefore, a clamping groove 352 adapted to the lower end of the wiping block 33 is provided at one end of the scraping plate 351. Bolts 34 threadedly connected to the wiping block 33 are symmetrically arranged on the scraping plate 351. By turning the bolts 34 to pull the bolts 34 out of the wiping block 33, the scraping plate 351 can be removed. When installing the wiping block 33 onto the wiping block 33, the lateral end of the wiping block 33 is inserted into the clamping groove 352, and then the bolts 34 are turned so that the bolts 34 pass through the scraping plate 351 and enter the wiping block 33, thereby realizing the installation of the scraping plate 351 onto the wiping block 33.
