Description

Technical Field

[0001] The utility model relates to the technical field of sizing machines, in particular to a starch feeding system for a film transfer sizing machine. Background Art

[0002] The surface starch enters the material chamber of the film transfer sizing machine through the starch feeding system, and then is transferred to the surface of the sizing roller through the metering rod. The glue on the surface of the sizing roller is then transferred to the paper to complete the sizing. In this process, the quality of the starch glue has a great impact on the film transfer sizing machine. During the sizing process of the film transfer sizing machine, only 10% of the starch glue will be brought to the paper, and 90% of the glue needs to be recycled. After these 90% of the glue comes into contact with the paper, it will contain some impurities such as fibers and sand particles. If it is not processed, it will cause abnormal wear of the metering rod, sticking of the rod, etc., and the machine will be removed early, affecting the operation of the sizing machine.

[0003] However, the starch glue liquid recovered by traditional equipment is filtered through a vibrating screen. Although a part of the fibers can be screened out, fine particles cannot be screened out, which will wear the metering rod and affect the operation of the sizing machine. Although the vibrating screen screens out a part of the fibers, these fibers are also slurry, and it is a bit wasteful to discharge them directly. In view of the above problems, the inventors proposed a membrane transfer sizing machine starch feeding system to solve the above problems. Utility Model Content
