A collecting frame 17 is installed at the bottom of the printing press warehouse 1. The staff starts the motor 3 to make the conveying device 6 inside the printing press warehouse 1 start to rotate, and then moves the round rod 8 upward to drive the hollow plate 9 to move upward. At this time, the cleaning brush 11 inside the hollow plate 9 will abut against the bottom of the conveying device 6, and then moves the pull plate 15 to drive the plug rod 16 to insert into the plug hole 12 to fix the position of the cleaning brush 11, so that the staff can easily clean the paper scraps and impurities on the conveying device 6 to prevent paper jams.

[0023] Reference Figure 4As shown, in this embodiment: a tension spring 18 is fixedly connected to the inside of the movable groove 13, and one end of the tension spring 18 is fixedly connected to the other end of the movable block 14. The setting of the tension spring 18 can give a certain tension to the movable block 14, so that the plug-in rod 16 can increase the rebound force when inserted into the inside of the plug-in hole 12, making it faster for the staff to use it.

[0024] Reference Figure 3 and Figure 4 As shown, in this embodiment: the surface of the plug rod 16 is slidably connected to the inside of the plug hole 12, the external shape of the plug rod 16 is consistent with the internal shape of the plug hole 12, and the sliding connection between the plug rod 16 and the plug hole 12 can ensure the stability and accuracy of the two during the connection process through the shape consistency, so that the plug rod 16 can be smoothly inserted into the plug hole 12 and is not easy to fall off or shake.

[0025] Reference Figure 4 and Figure 5 As shown, in this embodiment: slots 19 are provided on both sides of the hollow plate 9, and notches 20 are fixedly connected on both sides of the connecting block 10. A thrust spring 21 is fixedly connected inside the notch 20, and a pressing block 22 is fixedly connected to one side of the thrust spring 21. When the cleaning brush 11 needs to be disassembled, the round rod 8 can be moved downward, and then rotated with the round rod 8 to make the cleaning brush 11 face downward, and then the pressing block 22 is pressed to drive the pushing spring 21 to move toward the inside of the notch 20, so that the connecting block 10 can be taken out from the inside of the hollow plate 9, thereby cleaning the cleaning brush 11.

[0026] Reference Figure 4 As shown, in this embodiment: the material of the cleaning brush 11 is a polymer, which has good wear resistance and anti-aging properties, can maintain its cleaning effect during long-term use, reduce replacement frequency, and thus reduce maintenance costs.

Through the mutual cooperation of the threaded rod 26 and the threaded hole 23, the position of the collection frame 17 can be positioned, so that the staff can collect the waste debris after cleaning.

[0028] Reference Figure 6As shown, in this embodiment: a positioning groove 27 is provided at the bottom of the printing machine chamber 1, and a positioning block 28 is fixedly connected to the top of the collection frame 17. The cooperation between the positioning groove 27 and the positioning block 28 can ensure the precise positioning of the collection frame 17 at the bottom of the printing machine chamber 1, preventing the collection frame 17 from offsetting or shaking during use, thereby ensuring the stability and reliability of the collection frame 17.

[0029] Working principle: The staff starts the motor 3 to make the conveying device 6 inside the printing machine chamber 1 start to rotate, and then moves the round rod 8 upward to drive the hollow plate 9 to move upward. At this time, the cleaning brush 11 inside the hollow plate 9 will abut against the bottom of the conveying device 6, and then moves the pull plate 15 to drive the plug rod 16 to insert into the plug hole 12 to fix the position of the cleaning brush 11, so that the staff can easily clean the paper scraps and impurities on the conveying device 6 to prevent paper jams. The setting of the tension spring 18 can give a certain pulling force to the moving block 14, so that the plug rod 16 can increase the rebound force when inserted into the plug hole 12, making it faster for the staff to use. The sliding connection between the plug rod 16 and the plug hole 12 can ensure the stability and accuracy of the two during the connection process through the shape fit, so that the plug rod 16 can be smoothly inserted into the plug hole 12 and is not easy to fall off. The cleaning brush 11 may fall or shake. When the cleaning brush 11 needs to be disassembled, the round rod 8 can be moved downward, and then rotated with the round rod 8 to make the cleaning brush 11 face downward, and then the button 22 can be pressed to drive the push spring 21 to move toward the inside of the slot 20, so that the connecting block 10 can be taken out from the inside of the hollow plate 9, thereby cleaning the cleaning brush 11. The polymer material has good wear resistance and aging resistance, and can maintain its cleaning effect during long-term use, reduce the replacement frequency, and thus reduce maintenance costs. The position of the collection frame 17 can be positioned by the mutual use of the threaded rod 26 and the threaded hole 23, so that the staff can collect the waste debris after cleaning. The cooperation between the positioning groove 27 and the positioning block 28 can ensure the precise positioning of the collection frame 17 at the bottom of the printing chamber 1, preventing the collection frame 17 from offsetting or shaking during use, thereby ensuring the stability and reliability of the collection frame 17.
