Die cutting bottom roller, die cutting assembly and automatic die cutting machine

Abstract

The invention discloses a die-cutting bottom roller, which belongs to the field of die-cutting machines, and comprises a roller body, the surface of the roller body is provided with a cutting avoiding groove and an air suction hole, a die-cutting knife roller can be matched with two bottom rollers or a plurality of bottom rollers for multi-time die cutting, and the problem of low yield caused by incomplete waste removal during one-time forming of a film material can be avoided. The invention further discloses an automatic die-cutting machine, the automatic die-cutting machine comprises a die-cutting bottom roller and a knife roller which are fixed on a knife rest, the die-cutting bottom roller comprises a first bottom roller and a second bottom roller, the knife roller is located between the first bottom roller and the second bottom roller, and the knife roller is provided with an outer contour cutting edge and an inner contour cutting edge. The surface of the first bottom roller is provided with an outer contour cutting avoiding groove corresponding to the position of an outer contour blade of the knife roller. According to the automatic die-cutting machine, the design of the die-cutting bottom rollers is optimized, a compact and smooth two-bottom-roller and one-knife-roller structure is adopted, the working efficiency can be 1.5 times or above that of equipment of the same type, the waste material removing effect is remarkable, the rate of finished products can reach one hundred percent, and the automatic die-cutting machine can be applied to machining of mask materials, eye masks and the like.

Description

technical field [0001] The invention relates to a bottom roller, in particular to a die-cutting bottom roller used for processing and forming film materials such as facial masks. The invention also relates to a die-cutting assembly and an automatic die-cutting machine, belonging to the field of die-cutting. Background technique [0002] In the processing of film materials with outer and inner contours such as facial masks and eye masks, an automatic die-cutting machine with a die-cutting component is usually used. The traditional die-cutting component is mainly composed of a knife roller and a bottom roller. In order to separate the cut waste from the film, the waste will be removed by setting blowing or suction devices and installing scrapers. However, due to the design of die-cut workpieces such as the bottom roller and the blowing or suction methods In unreasonable places, the waste cannot be completely removed from the formed film, or the processing efficiency has to be ...

[0002] In the processing of film materials with outer and inner contours such as facial masks and eye masks, an automatic die-cutting machine with a die-cutting component is usually used. The traditional die-cutting component is mainly composed of a knife roller and a bottom roller. In order to separate the cut waste from the film, the waste will be removed by setting blowing or suction devices and installing scrapers. However, due to the design of die-cut workpieces such as the bottom roller and the blowing or suction methods In unreasonable places, the waste cannot be completely removed from the forming film, or the processing efficiency has to be reduced in order to remove the waste, such as adding manual sorting or adding knife rollers, etc.
