Two rollers 1 are fixedly connected to the outer walls of the two rotating shafts 1, and a conveyor belt is sleeved on the outer walls of the two rollers 1. The front side of the chassis is fixedly connected to a motor cover, and the inner wall of the cover is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the rotating shaft 1 on the left side through a coupling, and a gear 1 is fixedly connected to the front extension part of the rotating shaft 1 on the left side. Roller 2 is rotatably connected to the inner wall of the chassis, and the front side of the roller 2 rotates and extends outside the chassis.

[0008] Furthermore, a gear 2 is fixedly connected to the front extension portion of the roller 2, the gear 1 is meshed with the gear 2, and a plurality of rollers 3 are arranged above the conveyor belt.

[0009] Furthermore, the buffer assembly includes a rectangular block fixedly connected to the inner wall of the front side of the chassis, and the bottom of the rectangular block is hingedly provided with two hinged rods.

[0010] Furthermore, the bottoms of the two hinged rods are hingedly provided with hinge blocks, the bottoms of the hinge blocks are fixedly connected with sliders, a mounting plate is provided below the hinge blocks, and a sliding groove is provided in the mounting plate.

[0011] Furthermore, the inner wall of the slide is slidably connected to the two sliders, and the sides of the two sliders away from each other are fixedly connected to spring telescopic rods, and the sides of the two spring telescopic rods away from each other are fixedly connected to the inner wall of the slide, and the rear side of the mounting plate is rotatably connected to a plurality of rollers.

[0012] Furthermore, the guide mechanism includes a guide plate assembly and an adjustment assembly, the guide plate assembly includes a fixed rod fixedly connected to the inner wall of the chassis, the bottom of the fixed rod is slidably connected to two guide plates, and the two guide plates are threaded with a bidirectional threaded rod, and the rear side of the bidirectional threaded rod rotates and extends outside the chassis.

[0013] Furthermore, the adjustment assembly includes a limit plate fixedly connected to the rear extension of the bidirectional threaded rod, the rear side of the chassis is fixedly connected with a fixed block, and the rear side of the fixed block is hingedly provided with a limit rod.

[0014] Furthermore, a spring is fixedly connected to the front side of the limiting rod, the front side of the spring is fixedly connected to the chassis, and a knob is fixedly connected to the front extension of the bidirectional threaded rod.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up the anti-wrinkle mechanism, when in use, turn on the motor fixedly connected to the motor sleeve, and the motor drives the two rollers to rotate through the two rotating shafts. The rotation of the two rollers drives the conveyor belt to rotate. The conveyor belt on the left drives the gear 1 to rotate. The gear 1 drives the rotating shaft 2 to rotate through the gear 2, thereby driving the conveyor belt to rotate. Then the conveyor belt drives the roller 2 on it to rotate. At this time, the printing paper is fed into the guide mechanism through the paper inlet on the chassis. The paper is fed into the space between the rotating shaft 2 and the conveyor belt through the guide mechanism. The wrinkles on the paper are smoothed due to the squeezing of the two, and the conveyor belt and the rotating shaft 2 continue to rotate. The paper continues to rotate, thereby driving the paper under the second roller. The second roller is subjected to an upward force, thereby squeezing the two hinged rods away from each other, the two spring telescopic rods contract, and the two sliders operate. Then, the two spring telescopic rods contract, and the spring rebound force causes the second roller to further flatten the paper, preventing wrinkles from rebounding, so that the paper remains flat and wrinkle-free during transmission, reducing the occurrence of paper jams, and improving the stability and printing efficiency of the digital printing equipment. The buffer component ensures full contact between the paper and the second roller, making the force on the paper more uniform, improving the efficiency of smoothing wrinkles, and further improving the printing efficiency of the digital printing equipment.

[0017] 2. By setting up a buffer assembly, when the paper specifications need to be changed and the guide mechanism needs to be adjusted, first lift the limit rod backward and the spring will stretch. Due to the fixing effect of the fixed block, one end of the limit rod is lifted out of the groove on the limit plate, so that the bidirectional threaded rod can rotate. Then turn the knob, and the knob drives the guide plate assembly to rotate, thereby driving the two guide plates to slide on the fixed rod. Turn the knob counterclockwise to move the two closer to each other to adapt to smaller paper. Turn the knob clockwise to move the two away from each other to adapt to larger paper. The guide plate can guide the paper to be transmitted along a predetermined path to prevent paper jams caused by paper skew, curling or stacking. The adjustable distance feature enables the guide plate to fit closely to papers of different specifications. The guide plate distance can be adjusted by simple knob operation without the need for complicated disassembly and configuration process, which reduces the difficulty of operation and shortens the preparation time when changing paper specifications, thereby improving work efficiency.
