Description

Technical Field

[0001] The utility model relates to the technical field of diaper processing, in particular to a tool holder with a double supporting structure. Background Art

[0002] Diapers are disposable products made of non-woven fabrics, toilet paper, fluff pulp, polymer absorbent resin, PE film, rubber bands and other materials. There are two types: one for infants and one for adults. Since the sizes of diapers for infants and adults are different, the absorbent core of diapers needs to be cut into different sizes during the production process. The working parts of the upper roller and the bottom roller of the rotary die-cutting machine are both cylindrical. When working, the feed roller sends the material between the upper roller and the bottom roller, and the two clamp the material for die-cutting. Usually, the clamped material is formed by pressurizing the bearing position. The die-cutting roller rotates one circle to complete a working cycle. The middle rubber band cutting station of the fully automatic diaper production line has wider materials, a larger outer diameter of the roller, and the upper and lower rollers weigh several tons. In the later stage, the roller will be deformed under long-term pressure, sinking in the middle, and the material cannot be cut.

[0003] In view of the above situation, it is necessary to improve the roller cutter installation structure of the existing fully automatic diaper production line so that it can adapt to the current needs of diaper die-cutting processing. Utility Model Content
