[0035] An adjustment mechanism 7 is provided on the outside of the two guard plates 102, and the adjustment mechanism 7 includes a first hydraulic cylinder 701 and a second hydraulic cylinder 702 symmetrically arranged on the outside of the two guard plates 102, respectively. The tops of the two first hydraulic cylinders 701 and the second hydraulic cylinder 702 are respectively fixed with a first fixed block 7011 and a second fixed block 7021, a fixed rod 703 is axially connected between the first fixed block 7011 and the guard plate 102, and the second fixed block 7021 is axially connected to the side of the guard plate 102 with a movable rod 704, a movable groove 104 is opened on the outside of the guard plate 102, and one end of the movable rod 704 is slidably connected to the inside of the movable groove 104, the two first hydraulic cylinders 701 and the two second hydraulic cylinders 702 are symmetrically arranged outside the guard plate 102, and the guard plate is located at both ends of the unloading conveyor 1.

[0036] Specifically, after connecting to the external power supply, by starting the two first hydraulic cylinders 701 and the two second hydraulic cylinders 702, the first hydraulic cylinders 701 and the second hydraulic cylinders 702 respectively drive the first fixed block 7011 and the second fixed block 7021 to move up and down, and the first fixed block 7011 is connected to the guard plate 102 through the fixed rod 703, and the movable rod 704 of the second fixed block 7021 is slidably connected to the movable groove 104 on the guard plate 102, thereby achieving the height adjustment of the unloading conveyor 1, facilitating the docking of the unloading conveyor 1 with production equipment at different heights, improving adaptability, and facilitating the transportation of printed products;

[0037] When the two second hydraulic cylinders 702 are started separately, since the first fixed block 7011 and the fixed rod 703 are rotatably connected by bearings, and the fixed rod 703 is fixed to the guard plate 102, the second fixed block 7021 and the movable rod 704 are rotatably connected by bearings, and the movable rod 704 is slidably connected with the inside of the movable groove 104, when the second hydraulic cylinder 702 pushes one end of the discharge conveyor 1 to rise or fall, one end of the discharge conveyor 1 will perform a circular motion with the first fixed block 7011 as the center, so that the overall inclination of the discharge conveyor 1 can be adjusted, so that the discharge conveyor 1 can be docked with production equipment at different heights on both sides, further improving the adaptability, and through the provision of the movable groove 104, when one end of the discharge conveyor 1 performs a circular motion, the movable rod 704 can slide in the movable groove 104, thereby avoiding the movement of the movable rod 704 being restricted;

[0040] Through this arrangement, the contact surface between the movable rod 704 and the movable groove 104 is flat, which can reduce the wear of the movable rod 704 when sliding in the movable groove 104, and since the movable rod 704 and the second fixed block 7021 are connected by a bearing rotation, when the movable rod 704 is driven to rise or fall, the movable rod 704 can be rotated to an angle where the flat mouth part 705 is consistent with the inclination of the unloading conveyor 1, and always slides in the movable groove 104.

[0041] In the embodiment of the present utility model, reference Figure 1 and Figure 3 An elastic mechanism 5 is provided between the fixed frame 3 and the telescopic cylinder 4.

The connecting rod 504 passes through the movable frame 501 and is fixed to the fixed frame 3.

[0042] Specifically, when the finished printed product is transported by the conveyor belt 101 to contact the pressure wheel 301, the push of the finished printed product causes the pressure wheel 301 to rotate while the fixed frame 3 and the pressure wheel 301 move upward, thereby pushing the connecting rod 504 and the top plate 502 to squeeze the spring 503. At this time, the finished printed product has been pressed downward by the pressure wheel 301, and the squeezed spring 503 uses its elastic force to apply a downward thrust to the top plate 502. The top plate 502 transmits power to the fixed frame 3 through the connecting rod 504, thereby increasing the pressure applied by the pressure wheel 301 on the finished printed product, thereby improving the compaction effect of the finished printed product.

[0043] The movable frame 501 is driven by the telescopic cylinder 4, and the movable frame 501 drives the fixed frame 3 and the distance between the pressure wheel 301 and the conveyor belt 101 through the top plate 502 and the connecting rod 504, so that the pressure wheel 301 can match printed products of different thicknesses.

A wind pressure cover 604 is provided on the lower side of the front eaves portion 201, and the air guide duct group 603 passes through the front eaves portion 201 and is connected to the wind pressure cover 604.

[0045] Specifically, before the printed product contacts the pressing wheel 301, an external power supply is connected and the fan 601 is started. The fan 601 converts the external air into airflow and inputs it into the air duct group 603 through the air outlet pipe 602. The air duct group 603 is connected to the wind pressure hood 604 on the lower side of the front eaves 201, so that the airflow is blown downward from the wind pressure hood 604 and blown toward the printed product passing underneath, so that the paper sheets at the front end of the printed product are blown flat, preventing the paper sheets at the front end of the printed product from contacting the pressing wheel 301 when they are warped, causing the warped part to be folded in half after being compacted by the pressing wheel 301.

[0046] Preferably, an air duct bracket 8 is provided between the front eaves portion 201 and the air duct group 603 , and the air duct bracket 8 is used to support the air duct group 603 .
