Description

Technical Field

[0001] The invention relates to the technical field of chemical cellulose production, and in particular to a method for cleaning a slicer cross blade. Background Art

[0002] The company currently has a slicer for cutting cotton paddles and wood pulp boards. The paddles are cut by a longitudinal cutter and then cut into rectangular particles by a cross-cutter. During continuous production, some of the uncut particles will adhere to the knife groove of the cross-cut knife. When the knife groove is filled, it will be repeatedly squeezed with the bottom knife, causing increased vibration of the equipment and even ultra-high interlock shutdown. The equipment is unstable and needs to be shut down to clean the adhered pulp board particles in the cross-cut knife groove to maintain the cutting effect, which affects the continuous operation of production and is very likely to cause machine damage accidents.

[0003] The existing method of cleaning the slicer cross blade usually requires the equipment to be shut down so that the staff can clean the adhered pulp board particles in the cross-cutting blade groove. It is difficult to ensure the cleaning effect by staff, and there is often a problem of incomplete cleaning. At the same time, it is time-consuming and labor-intensive, affecting the continuous operation of production.

[0004] In view of the existing slicer cross-knife cleaning method, it is difficult to ensure the cleaning effect by manual cleaning, and there is often a problem of incomplete cleaning. At the same time, it is time-consuming and labor-intensive, which affects the continuous operation of production. The slicer cross-knife cleaning method adds a purge device and uses compressed air to clean the cross-cutting knife online without stopping the machine, which greatly improves the cleaning efficiency and production continuity. At the same time, by accurately designing the installation position and purge parameters of the purge device, it is ensured that the cleaning effect is effectively improved, avoiding the need to frequently open the cover to clean the equipment. Summary of the invention

[0005] In order to overcome the existing method of cleaning the cross-cutting knife of the slicer, it is usually necessary to shut down the equipment so that the staff can clean the adhered pulp board particles in the cross-cutting knife groove. It is difficult to ensure the cleaning effect by staff, and there is often a problem of incomplete cleaning. At the same time, it is time-consuming and labor-intensive, which affects the continuous operation of production.

It is difficult to ensure the cleaning effect by staff cleaning, and there is often a problem of incomplete cleaning. At the same time, it is time-consuming and labor-intensive, which affects the continuous operation of production. The slicer cross-knife cleaning method adds a purge device and uses compressed air to clean the cross-cutting knife online without stopping the machine, which greatly improves the cleaning efficiency and production continuity. At the same time, by accurately designing the installation position and purge parameters of the purge device, it is ensured that the cleaning effect is effectively improved, avoiding the need to frequently open the cover to clean the equipment; 2. By adding a purging device with evenly distributed air holes near the middle of the cross-cutting knife in the machine, and by accurately controlling parameters such as the air hole diameter, purging distance and purging angle, the cross-cutting knife can be effectively cleaned. At the same time, an automated cleaning method is adopted to reduce manual intervention, improve the safety of the cleaning process, and greatly improve the cleaning efficiency and production continuity.
