[0023] Reference Figure 1 and Figure 2This application provides a material discharge device for a printing press, comprising: a printing press body 100, with a frame 110 disposed at its discharge end; a lifting platform 200, which is lifted and disposed on the frame 110; a tray 300, located on the lifting platform 200, the tray 300 being used for stacking materials; and a guiding mechanism, including a guide rail assembly and rollers 430, the guide rail assembly including a first guide rail 410 and a second guide rail 420, the first guide rail 410 being disposed on the lifting platform 200, and the second guide rail 420 being disposed on the ground on one side of the lifting platform 200, the length direction of the second guide rail 420 being parallel to that of the first guide rail 410. The length direction is consistent. When the lifting platform 200 is at the lowest position, the first guide rail 410 and the second guide rail 420 are connected. The roller 430 is set at the bottom of the tray 300 and is connected to the guide rail assembly. The limiting mechanism 500 includes a mounting rod 510 and a baffle 520. The mounting rod 510 is slidably set on the frame 110. The sliding direction of the mounting rod 510 is consistent with the discharge direction of the printing machine body 100. The baffle 520 is vertically set on the side of the mounting rod 510 near the tray 300. The baffle 520 is used to limit the displacement of the material on the tray 300.

[0024] The material is printed by the printing press body 100 and then output from the discharge end of the printing press body 100. The lifting platform 200 rises to a set position, and the tray 300 receives the material output from the discharge end of the printing press body 100. Each time the tray 300 receives a piece of material, the lifting platform 200 descends one level. When the material on the tray 300 reaches a certain quantity, the lifting platform 200 drives the tray 300 to descend to the lowest position, so that the first guide rail 410 on the lifting platform 200 connects with the second guide rail 420 on the ground. At this time, the tray 300 is pulled, so that the tray 300 carries the material along the first guide rail 410 and into the second guide rail 420, thereby removing the tray 300 from the lifting platform 200. With the rollers 430 working in conjunction with the guide rail assembly, the pallet 300 can be moved away from the lifting platform 200 simply by pulling it. Compared to the method of using both hands to move the pallet 300 in related technologies, this reduces labor intensity and improves work efficiency. By setting a limit mechanism 500, the material output from the discharge end of the printing machine body 100 onto the pallet 300 can be limited, preventing the material from flying off the pallet 300 and improving the stability and reliability of material collection.

[0025] The first guide rail 410 and the second guide rail 420 are provided with protrusions 440, and the roller 430 is provided with a groove 450. The protrusions 440 and the grooves 450 are connected in a cooperative manner. The cooperation between the protrusions 440 and the grooves 450 allows the pallet 300 to move in a fixed direction, improving the stability and reliability of the pallet 300's movement. It is conceivable that the roller 430 is equipped with a brake assembly to limit its rotation. By providing a brake assembly, the position of the pallet 300 can be fixed, preventing the pallet 300 from moving arbitrarily and affecting the smooth collection process, thus improving the stability and reliability of the collection. It is easy to understand that the pallet 300 is provided with a handle 310 for pulling the pallet 300 along the guide rail assembly; the structure is simple and the operation is convenient. Of course, the handle 310 can also be provided in other positions on the pallet 300; this application does not limit this.

[0026] Reference Figure 1 and Figure 2 In this embodiment, the frame 110 is equipped with a lifting mechanism, and the lifting platform 200 is connected to the lifting mechanism. The lifting mechanism drives the lifting platform 200 to move up and down. Specifically, the lifting mechanism includes a screw 120, a nut seat 130, a pulley 140, and a chain 150. The screw 120 is rotatably mounted on the frame 110, the nut seat 130 is mounted on the lifting platform 200, and the nut seat 130 is connected to the screw 120. The pulley 140 is rotatably mounted above the side of the lifting platform 200 near the printing machine body 100. The chain 150 is wound around the pulley 140, so that both ends of the chain 150 are connected to the printing machine body 100 and the lifting platform 200, respectively. The rotation of the screw 120 causes the nut seat 130 to drive the lifting platform 200 to move up and down. At the same time, the pulley 140 and the chain 150 work together to ensure the stability of the lifting platform 200 during movement.

[0027] Reference Figure 1 and Figure 2 In some embodiments of this application, the frame 110 is provided with a material-grabbing mechanism, which is used to pick up the material output from the printing press body 100 and transfer it to the tray 300. Specifically, the material-grabbing mechanism includes a horizontal movement component 160, a vertical movement component 170, and a suction cup 180. The horizontal movement component 160 is arranged along the discharge direction of the printing press body 100, the vertical movement component 170 is arranged above the horizontal movement component 160, and the suction cup 180 is arranged above the vertical movement component 170. The horizontal movement component 160 drives the suction cup 180 to move onto the conveying component, and the vertical movement component 170 drives the suction cup 180 to descend to pick up the material; the vertical movement component 170 drives the suction cup 180 to rise, while the horizontal movement component 160 drives the suction cup 180 to transport it above the tray 300; the vertical movement component 170 drives the suction cup 180 to descend to place the material on the tray 300. By adopting the above structure, automatic material unloading is achieved, reducing labor intensity and improving work efficiency.

[0028] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
