[0022] Reference Figures 1-4 A high-speed paper machine headbox includes a working shell 1 with multiple bases. A feed pipe 2 is provided on the working shell 1 to facilitate the entry and discharge of pulp raw materials. The feed pipe 2 is set through the working shell 1. A sealed piston is provided in the feed pipe 2. The sealed piston is made of rubber. The sealed piston and the feed pipe 2 are matched to prevent pulp from splashing out during processing. A pulp chamber 3 is provided in the working shell 1. A working shaft 4 is rotatably connected to the inner wall of the pulp chamber 3. A working motor 5 is fixedly connected to the outer wall of the working shell 1. The output end of the working motor 5 is set through the working shell 1. One end of the working shaft 4 and the output end of the working motor 5 are connected. The outlet end is fixedly connected, and a plurality of stirring rods are provided on the working shaft 4, so that the pulp raw material can be stirred and processed. Two reciprocating screws 6 are rotatably connected in the pulping chamber 3, and the two reciprocating screws 6 are symmetrically arranged about the working shaft 4. Two working slides 7 are also fixedly connected in the pulping chamber 3, and the two working slides 7 are respectively matched with the two reciprocating screws 6. A working slider 8 is slidably connected to the two working slides 7, and the two working sliders 8 are respectively threadedly connected to the two reciprocating screws 6. The working slide 7 limits the working slider 8 so that the working slider 8 can only slide left and right along the direction of the reciprocating screw 6;

[0023] The two working sliders 8 are each provided with a brush assembly 9, and the two brush assemblies 9 are respectively arranged in cooperation with the two inner side walls of the slurry chamber 3, so that the inner side walls of the slurry chamber 3 can be cleaned. A transmission assembly is also provided in the slurry chamber 3, and the transmission assembly includes a working gear 10 fixedly connected to one of the reciprocating screws 6, and a working gear 2 11 is fixedly connected to the other reciprocating screw 6. A transmission chain 12 is provided on the working gear 10 and the working gear 2 11. An auxiliary motor 13 is also fixedly connected to the working housing 1, and the output end of the auxiliary motor 13 is arranged through the working housing 1. The output end of the auxiliary motor 13 is fixedly connected to one of the reciprocating screws 6. Due to the characteristics of the chain drive, when the working gear 10 rotates, the working gear 2 11 will also be driven to rotate;

[0024] The working shell 1 is also provided with a fixing assembly, which includes a fixing block 14 fixedly connected to the outer wall of the working shell 1, a working chamber 15 is provided in the fixing block 14, a threaded sleeve 16 is rotatably connected in the working chamber 15, one end of the threaded sleeve 16 passes through the fixing block 14, a turning handle is provided on the threaded sleeve 16, and the turning handle is disc-shaped. The turning handle and the threaded sleeve 16 are matched to make it more convenient for the staff to rotate the threaded sleeve 16, and a working screw 17 is connected to the inner thread of the threaded sleeve 16. The end of the working screw 17 away from the threaded sleeve 16 is fixedly connected to the working suction cup 18. During the downward movement of the working suction cup 18, due to the flow The weight of the pulp box will be continuously squeezed, thereby forming a negative pressure, thereby forming an adsorption and fixing effect, avoiding problems such as shaking and sliding in the pulp box. A working opening is provided on the fixed block 14, and the working suction cup 18 and the working opening are arranged in coordination. A limiting component is also provided in the working chamber 15, and the limiting component includes a limiting plate 19 fixedly connected to the inner wall of the working chamber 15, and the working screw 17 slides through the limiting plate 19. A limiting block is provided on the limiting plate 19, and a limiting groove is provided on the working screw 17. The limiting block and the limiting groove are arranged in coordination, thereby limiting the working screw 17 so that it can only slide up and down along the direction of the threaded sleeve 16.

[0025] During the use of the present invention, the staff first adds pulp raw materials from the feed pipe 2, then uses the sealing piston to close the feed pipe 2, and starts the working motor 5, so that the working shaft 4 fixedly connected to the output end of the working motor 5 rotates, thereby driving the multiple stirring rods to rotate, thereby stirring the pulp raw materials. After the stirring is completed, the staff first rotates the threaded sleeve 16. Due to the characteristics of the threaded connection, the working screw 17 will slide downward along the direction of the threaded sleeve 16 under the limiting action of the limiting plate 19, thereby driving the working suction cup 18 to move. Due to the gravity of the headbox itself, the working suction cup 18 will be continuously squeezed, thereby forming a negative pressure, thereby forming an adsorption and fixing effect. Then the staff can send the pulp from the headbox into the paper machine;

[0026] When the slurry box needs to be cleaned, the staff first adds clean water to the slurry chamber 3, and then starts the auxiliary motor 13 to rotate the reciprocating screw 6 fixedly connected to the output end of the auxiliary motor 13. Under the limiting action of the working slide bar 7, the working slider 8 will slide back and forth along the reciprocating screw 6, and drive the brush assembly 9 to move together, so that one side wall of the slurry chamber 3 can be scraped and cleaned. At the same time, when the reciprocating screw 6 rotates, it will drive the working gear 10 to rotate. Due to the characteristics of the chain drive, with the cooperation of the transmission chain 12, the working gear 2 11 will also start to rotate, and then drive the other reciprocating screw 6 to rotate, thereby completing the cleaning of the other side wall of the slurry chamber 3 according to the above transmission. Finally, the staff only needs to pour out the waste water.
