Description

Technical Field

[0001] This utility model relates to the field of high-speed printing press technology, and more specifically, to a processing waste material transfer device for a high-speed printing press. Background Technology

[0002] High-speed printing presses are devices capable of large-scale, high-efficiency printing production, widely used in newspapers, magazines, packaging, and commercial printing. Their core characteristic is their ability to complete a large number of printing jobs per unit of time, typically operating at speeds of thousands or even tens of thousands of sheets per hour, significantly higher than traditional printing presses.

[0003] A search revealed a utility model patent with publication number CN214454347U, which discloses a processing waste transfer device for a high-speed printing press. Suitable for installation over short vertical distances, the device includes a base frame, a conveyor belt assembly, and a drive assembly. The base frame comprises two frame assemblies. The conveyor belt assembly includes a first transmission roller, a second transmission roller, and a conveyor belt. The drive assembly includes a drive motor and a worm gear reducer. The frame assembly includes multiple second frame rods, which are staggered across different frame assemblies. The reprocessing pit is located below the second transmission roller. When the drive motor outputs torque to the first transmission roller through the worm gear reducer, it drives the first transmission roller to move the conveyor belt, thereby transferring the processing waste falling from the high-speed printing press into the reprocessing pit. However, this patent has the following shortcomings: after using the conveyor belt to transfer the processing waste, it is not easy to ensure that the waste completely falls off; some paper scraps easily adhere to the conveyor belt. Waste falling from the bottom of the high-speed printing press is prone to drifting and may not fall onto the conveyor belt. Therefore, we propose a processing waste material transfer device for high-speed printing presses. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a processing waste material transfer device for a high-speed printing machine.

[0010] In a preferred embodiment of this utility model, the side of the movable seat is in contact with the inner wall of another movable slot.

[0011] Compared with the prior art, the advantages of this utility model are: (1) In this utility model, the geared motor drives the rotating rod and the second spur gear to rotate clockwise, the meshing transmission between the second spur gear and the first spur gear drives the conveyor roller to rotate counterclockwise, the conveyor roller drives the conveyor belt to rotate, and the conveyor belt is used to transport the fallen processing waste. When the waste falls at the end of the conveyor belt, the brush is used to clean the end of the conveyor belt to ensure that the waste falls completely.

[0012] (2) In this utility model, the screw and the moving seat can drive the lower baffle frame, the stretching rubber frame and the top frame to move, so that the top frame moves to the right below the discharge port of the high-speed printing machine. The electric push rod and the push block are used to drive the top frame to move up and abut against the outer side of the discharge port of the printing machine. The top frame, the stretching rubber frame and the lower baffle frame block the falling processing waste, ensuring that the waste can fall smoothly onto the conveyor belt for conveying and conversion, and avoiding the waste from scattering and flying when it falls.

Example 2

[0021] Based on Embodiment 1, as shown in Figures 1 to 3, the moving mechanism 2 includes two moving slots 12 disposed on the top of the base frame 1. A slide rod 13 is fixedly sleeved in the inner cavity of one moving slot 12, and a screw 14 is rotatably connected to the inner cavity of the other moving slot 12. The end of the screw 14 extends to the outside of the base frame 1 and is fixedly connected to a knob 17. A moving seat 16 is threadedly sleeved on the outer side of the screw 14. The moving seat 16 is provided with a screw hole that matches the screw 14, ensuring smooth threaded transmission between the screw 14 and the moving seat 16. A slider 15 is movably sleeved on the outer side of the slide rod 13. The blocking mechanism 3 includes a lower stop frame 18 fixedly connected to the top surface of the slider 15 and the moving seat 16. A tension rubber frame 19 is fixedly connected to the top surface of the lower stop frame 18, and a top frame 20 is fixedly connected to the top end of the tension rubber frame 19. The top frame 20, the tension rubber frame 19, and the lower stop frame 18 are all connected together. The inner sides are flush with each other. Push blocks 23 are provided on both sides of the top frame 20, and mounting seats 21 are provided on both sides of the lower stop frame 18. Electric push rods 22 are fixedly installed on the two mounting seats 21 respectively. The top ends of the two electric push rods 22 are connected to the bottom surface of the push blocks 23 respectively. The two electric push rods 22 are controlled by a synchronous controller to ensure that the two electric push rods 22 can smoothly drive the top frame 20 to move up and down. The electric push rods 22 are powered by an external power supply. Example 3

[0022] Based on Embodiment 1 and Embodiment 2, as shown in Figure 3, the two sides of the conveyor belt 5 are in contact with the inner side of the base frame 1 to prevent the excess material conveyed on the conveyor belt 5 from falling off the side of the conveyor belt 5. The side of the slider 15 is in contact with the inner wall of a moving groove 12, and the side of the moving seat 16 is in contact with the inner wall of another moving groove 12 to ensure the stability of the slider 15 and the moving seat 16 in the inner cavity of the moving groove 12.

[0023] It should be noted that this utility model is a processing waste material transfer device for a high-speed printing machine. In use, firstly, rotating the knob 17 drives the screw 14 to rotate. Through the threaded engagement between the screw 14 and the moving seat 16, the moving seat 16, the lower baffle frame 18, the stretching rubber frame 19, and the top frame 20 move, causing the top frame 20 to move directly below the waste material drop outlet of the high-speed printing machine. Then, starting the electric push rod 22 drives the push block 23 to move upwards. The push block 23 then drives the top frame 20 to move upwards synchronously, causing the stretching rubber frame 19 to stretch, so that the top surface of the top frame 20 abuts against the outer surface of the waste material drop outlet of the printing machine. Next, starting the reduction motor 9 drives the rotating rod 7 and the second spur gear 11 to rotate clockwise. The meshing transmission between the second spur gear 11 and the first spur gear 10 drives the conveyor roller 4 to rotate counterclockwise, and the conveyor roller 4 drives the conveyor belt 5. The machine rotates, and finally the leftover material falling from the printing press's leftover material drop outlet falls onto the conveyor belt 5 from the inside of the top frame 20, the stretch rubber frame 19, and the lower baffle frame 18. The conveyor belt 5 is used to transport the leftover material until it is transported to the external processing pit. At the same time, the brush 8 is used to clean the end of the conveyor belt 5 to ensure that the leftover material falls completely.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
