[0023] like Figures 1 to 3 As shown, a paper pressing device for a paper mounting machine comprises a base 1, a sliding mechanism 3 is provided on the top surface of the base 1, a backing plate 2 is fixedly installed on the rear side of the top surface of the base 1, a limit plate 4 is fixedly installed on the surface of the sliding mechanism 3, a positioning mechanism 5 is provided on the surface of the limit plate 4, a lifting mechanism 6 and a telescopic mechanism 7 are provided on the surface of the backing plate 2, a telescopic rod 10 is fixedly installed on the surface of the lifting mechanism 6, a pressing seat 8 is fixedly installed on the end of the telescopic rod 10 away from the lifting mechanism 6, the telescopic mechanism 7 is fixedly installed on the rear surface of the pressing seat 8, a pressing mechanism 9 is provided on the bottom surface of the pressing seat 8, a second electric telescopic rod 11 is fixedly installed on the top surface of the pressing seat 8, and the number of the second electric telescopic rods 11 is several.

[0024] Specifically, the sliding mechanism 3 can be any structure with a moving function, such as a threaded rod and an electric push rod. The paper to be mounted is placed on the top surface of the base 1 and close to the surface of the backing plate 2. The sliding mechanism 3 drives the limiting plate 4 to move toward the backing plate 2 until it is close to the paper to perform a preliminary limit on it. The positioning mechanism 5 is adjusted so that both sides of the paper can be limited, which can adapt to papers of different specifications and further fix the paper. The lifting mechanism 6 on the surface of the backing plate 2 drives the telescopic rod 10, the telescopic mechanism 7, the pressing seat 8 and the pressing mechanism 9 to be lifted and lowered. The pressing mechanism 9 can squeeze the paper. The second electric telescopic rod 11 pushes the pressing mechanism 9 to contact the paper. The pressing force of the pressing mechanism 9 for papers of different thicknesses can be adjusted to further fix the paper and prevent the paper position from being offset. The telescopic mechanism 7 cooperates with the telescopic rod 10 to push the pressing seat 8 and the pressing mechanism 9 to move on the paper surface, so that the paper is laid more smoothly, avoiding the unevenness and uneven pressing of the subsequent mounted paper, ensuring the quality of the mounted paper and facilitating the production of subsequent printed products.

[0025] like Figures 1 to 3 As shown, the positioning mechanism 5 includes a first slide groove 501, the first slide groove 501 is opened on the surface of the limit plate 4, a first motor 503 is fixedly installed on the side of the limit plate 4, the output end of the first motor 503 is fixedly connected with a double-headed threaded rod 502, the double-headed threaded rod 502 is rotatably installed on the inner wall surface of the first slide groove 501, a first slider 504 is slidably installed on the inner wall surface of the first slide groove 501, the number of the first sliders 504 is two and they are respectively threadedly connected to the two ends of the double-headed threaded rod 502, and a positioning plate 505 is fixedly installed on the surface of the first slider 504.

[0026] Specifically, the double-headed threaded rod 502 is driven to rotate by the output end of the first motor 503, thereby driving the first slider 504, which is threadedly sleeved on the surface of the double-headed threaded rod 502 and slidably installed on the inner wall surface of the first slide groove 501, to move toward each other in the first slide groove 501, and then driving the positioning plate 505 fixedly installed on the surface of the first slider 504 to move toward each other until it is close to both sides of the paper, thereby further fixing the position of papers of different specifications, which is convenient for subsequent paper mounting.

[0027] like Figures 1 to 3 As shown, the lifting mechanism 6 includes a second slide groove 601, which is opened on the surface of the support plate 2, and a second motor 602 is fixedly installed on the top surface of the support plate 2. The output end of the second motor 602 is fixedly connected to a threaded rod 603, and the threaded rod 603 is rotatably installed on the inner wall surface of the second slide groove 601. A second slider 604 is threadedly sleeved on the surface of the threaded rod 603, and the second slider 604 is slidably installed on the inner wall surface of the second slide groove 601, and the telescopic rod 10 is fixedly installed on the surface of the second slider 604.

[0028] Specifically, the output end of the second motor 602 rotates to drive the threaded rod 603 to rotate, thereby driving the second slider 604, which is threadedly sleeved on the surface of the threaded rod 603 and slidably installed on the inner wall surface of the second slide groove 601, to rise and fall, thereby driving the telescopic rod 10 fixedly installed on the surface of the second slider 604 to rise and fall, and then driving the pressing seat 8 and the pressing mechanism 9 to rise and fall, so as to facilitate the preliminary pressure adjustment of the paper.

[0029] like Figure 3 As shown, the pressing mechanism 9 includes a sleeve rod 901 and a pressure roller 905. The sleeve rod 901 is fixedly installed on the bottom surface of the pressing seat 8. A slide plate 903 is slidably installed on the inner wall surface of the sleeve rod 901. A spring 902 is fixedly connected between the upper surface of the slide plate 903 and the inner wall top surface of the sleeve rod 901. A support frame 904 is fixedly installed on the bottom surface of the slide plate 903. The support frame 904 is slidably inserted into the bottom surface of the sleeve rod 901, and the pressure roller 905 is rotatably installed on the surface of the support frame 904.

[0030] Specifically, when the laminating mechanism 9 gradually moves downward and contacts the paper surface, the pressure roller 905 is subjected to upward pressure, so that the support frame 904 is subjected to upward pressure and drives the slide plate 903 to slide upward on the inner wall surface of the sleeve rod 901. At the same time, the spring 902 is squeezed and deformed, and under the elastic force, a downward force is generated on the slide plate 903, the support frame 904 and the pressure roller 905, so that pressure is generated on the paper, which facilitates the fixation of the paper and prevents the position of the paper from shifting.

[0031] like Figures 1 to 3 As shown, the telescopic mechanism 7 includes a through slot 701, which is opened on the surface of the back plate 2, and a third slider 702 is slidably installed on the inner wall surface of the through slot 701. A first electric telescopic rod 703 is fixedly installed behind the third slider 702, and the telescopic end of the first electric telescopic rod 703 is fixedly installed on the rear surface of the pressing seat 8.

[0032] Specifically, while the lifting mechanism 6 drives the pressing seat 8 to rise and fall, it drives the first electric telescopic rod 703 and the third slider 702 to slide up and down along the inner wall surface of the through groove 701. The first electric telescopic rod 703 can push the pressing seat 8 and the pressing mechanism 9 to move forward and backward, thereby driving the pressing roller 905 to roll back and forth on the surface of the paper, which is beneficial to adjust the flatness of the paper and facilitates the subsequent mounting of the paper.

[0033] like Figures 1 to 3 As shown, there are several pressing mechanisms 9 and they are evenly arranged on the bottom surface of the pressing seat 8. The middle pressing mechanism 9 is fixedly installed on the bottom surface of the pressing seat 8, and the pressing mechanisms 9 on both sides are slidably inserted into the bottom surface of the pressing seat 8 and fixedly connected to the telescopic end of the second electric telescopic rod 11.

[0034] Specifically, the pressing mechanism 9 in the middle is used to perform preliminary squeezing and fixing of the paper, and the pressing mechanisms 9 on both sides are slidably inserted into the bottom surface of the pressing seat 8. After the paper is initially squeezed and fixed, the pressing mechanisms 9 on both sides can be pushed downward by the second electric telescopic rod 11 to further squeeze and fix the paper, so as to facilitate the adjustment of the pressure required for mounting paper of different thicknesses, thereby avoiding problems such as uneven paper and uneven pressing.

[0035] In summary: the paper to be mounted is placed on the top surface of the base 1 and is close to the surface of the backing plate 2. The limiting plate 4 is driven by the sliding mechanism 3 to move toward the backing plate 2 until it is close to the paper to perform a preliminary limit on it. The positioning mechanism 5 is adjusted so that both sides of the paper can be limited, which can adapt to papers of different specifications and further fix the paper. The pressing seat 8 and the pressing mechanism 9 are driven to rise and fall by the lifting mechanism 6. The pressing mechanism 9 is pushed to contact the paper by the second electric telescopic rod 11. The pressing force of the pressing mechanism 9 for papers of different thicknesses can be adjusted to further fix the paper and prevent the paper position from shifting. The telescopic mechanism 7 cooperates with the telescopic rod 10 to push the pressing mechanism 9 to move on the surface of the paper, so that the paper is laid more smoothly, avoiding the unevenness and uneven pressing of the subsequent mounted paper, ensuring the quality of the mounted paper and facilitating the production of subsequent printed products.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
