[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0021] like Figures 1-2 As shown, an adjustable pressing device suitable for paper of different thicknesses includes an outer frame 1, pressing components 4, and a dust removal component 5. Two unwinding drums 2 are rotatably mounted on the left side of the outer frame 1 via a rotating shaft, and two sets of pressing components 4 are mounted on the right side of the outer frame 1. Four sets of traction rollers 3 are symmetrically mounted on both sides of the middle of the outer frame 1, and the traction rollers 3 are rotatably connected to the outer frame 1. A glue application component 7 is located on the right side of the dust removal component 5, and the glue application component 7 includes a glue spray pipe 701 and a nozzle 702. The glue spray pipe 701 is fixedly connected to the side wall of the outer frame 1, and the lower side of the glue spray pipe 701 is equidistant from each other. The glue application assembly 7 is equipped with a nozzle 702 and also includes a glue delivery pipe 703. The other side of the glue spraying pipe 701 is connected to the glue delivery pipe 703. Each traction roller group 3 is provided with two parallel roller shafts for traction of the paper on the outside of the unwinding drum 2, so that the upper and lower layers of paper in the middle position are arranged in parallel to facilitate dust removal and glue application. The traction roller shaft and the rear end of the unwinding drum 2 are both equipped with corresponding rotary motors. The glue delivery pipe 703 is used to send the stored glue into the inside of the glue spraying pipe 701, so that the surface of the lower paper is evenly sprayed with glue through the evenly distributed nozzles 702 to facilitate subsequent pressing processing.

[0022] like Figure 1As shown, the pressing assembly 4 includes a mounting plate 401 and an electric telescopic rod 402. The mounting plate 401 is fixedly connected to the side wall of the outer frame 1, and the electric telescopic rod 402 is installed on the side of the mounting plate 401 near the middle of the outer frame 1. The pressing assembly 4 also includes a movable frame 403 and a pressing roller 404. The other end of the electric telescopic rod 402 is fixed to the movable frame 403, and the movable frame 403 is slidably connected to the side wall of the outer frame 1. The pressing roller 404 is rotatably arranged inside the movable frame 403. The extension and retraction of the electric telescopic rod 402 facilitates the lifting and lowering of the movable frame 403, thereby adjusting the distance between the pressing roller 404 and the paper to adjust the pressing pressure. It is suitable for paper of different thicknesses. The upper and lower pressing rollers 404 are arranged in cooperation to press the double-layer paper.

[0023] like Figures 2-3 As shown, a dust removal assembly 5 is installed in the middle of the outer frame 1. The dust removal assembly 5 includes a negative pressure pipe 501, a corrugated connecting pipe 502, a dust suction hood 503, a side plate 507, and an electrostatic dust suction wiper 508. The negative pressure pipe 501 is fixedly connected to the side wall of the outer frame 1. The upper and lower sides of the negative pressure pipe 501 are connected to the dust suction hood 503 through the corrugated connecting pipe 502. The right side of the upper and lower dust suction hoods 503 are fixed with side plates 507, and the outer side of the side plates 507 is attached to the electrostatic dust suction wiper 508 with Velcro. The dust removal assembly 5 also includes a fixing plate 504, a mini telescopic rod 505, and a lifting plate 506. The left side of the negative pressure pipe 501 is fixed with the fixing plate 504, and the upper middle part of the fixing plate 504 is equipped with a mini telescopic rod 505. A lifting plate 506 is fixed to the top of the 5, and the lifting plate 506 is fixed to the left side of the dust collection hood 503. The position and height of the lifting plate 506 and the dust collection hood 503 can be easily adjusted by the extension and retraction of the micro telescopic rod 505, so that the dust collection hood 503 fits against the surface of the paper, which is suitable for paper of different thicknesses. The corrugated connecting tube 502 can extend and retract accordingly to cooperate with the lifting and retraction of the dust collection hood 503. The negative pressure tube 501 generates negative pressure so that the dust collection hood 503 can adsorb dust on the surface of the paper. Then, the electrostatic dust collector 508 can electrostatically adsorb the residual dust on the surface of the paper, so that there is no dust between the two layers of paper, which facilitates the pressing of the two. The electrostatic dust collector 508 contains a charge device inside, which generates a high voltage electrostatic field through power supply, which facilitates electrostatic dust collection.

[0024] like Figure 2As shown, a dust collection assembly 6 is installed on the outside of the negative pressure pipe 501. The dust collection assembly 6 includes a dust collection pipe 601, a dust collection box 602, and a negative pressure fan 603. The dust collection box 602 is connected to the lower side of the dust collection pipe 601, and the negative pressure fan 603 is embedded in the side of the dust collection box 602. The negative pressure pipe 501 is interconnected with the dust collection box 602 through the dust collection pipe 601, and a ventilated intercepting filter is provided between the dust collection box 602 and the negative pressure fan 603. The negative pressure fan 603 creates a negative pressure inside the dust collection box 602. The dust collection box 602 is connected to the negative pressure pipe 501 through the dust collection pipe 601, thereby creating a negative pressure inside the negative pressure pipe 501, which facilitates the dust collection of the negative pressure pipe 501.

[0025] In summary, as Figures 1-3 As shown, this adjustable pressing device, suitable for paper of different thicknesses, firstly allows the upper and lower unwinding drums 2 to roll the paper, and then the traction roller group 3 pulls and moves the paper on the outside of the unwinding drum 2. Each traction roller group 3 is equipped with two parallel roller shafts, so that the upper and lower layers of paper in the middle position are arranged in parallel. Then, the position and height of the lifting plate 506 and the dust suction hood 503 are adjusted by the extension and retraction of the micro telescopic rod 505, so that the dust suction hood 503 fits against the surface of the paper. It is suitable for paper of different thicknesses. The corrugated connecting pipe 502 can extend and retract accordingly to cooperate with the lifting and lowering of the dust suction hood 503. At this time, the negative pressure fan 603 generates negative pressure inside the negative pressure pipe 501. The negative pressure generated by the negative pressure pipe 501 causes the dust suction hood 503 to adsorb dust and debris on the surface of the paper. The adsorbed dust particles can enter the dust collection box 602 through the suction pipe 601. Then, the electrostatic dust collector 508 can electrostatically adsorb the residual dust particles on the paper surface, so that there are no dust particles between the two layers of paper. Next, the glue delivery pipe 703 delivers the stored glue into the glue spraying pipe 701, so that the glue is evenly sprayed onto the surface of the lower paper through the evenly distributed nozzles 702. Then, during pressing, the extension and retraction of the electric telescopic rod 402 drives the moving frame 403 to rise and fall, thereby adjusting the distance between the pressing roller 404 and the paper to adjust the pressing pressure, which is suitable for paper of different thicknesses. Finally, the upper and lower pressing rollers 404 are set together to press the two layers of paper together. This completes the use process of the adjustable pressing device suitable for paper of different thicknesses.
