Detailed Description
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses an automatic clear useless structure of glued membrane die-cutting, including supplying glued membrane migration to cut to hold and cut platform 1, hold and cut 1 top and slide along vertical direction and be provided with by cylinder or hydraulic cylinder driven die-cutting rule 2. The adhesive film passes through the gap between the bearing cutting table 1 and the die-cutting knife 2.
The middle part of the die-cutting rule 2 is provided with a blowing through hole 21, and the axial direction of the blowing through hole 21 is the same as the migration direction of the glue film, so that the two ends of the blowing through hole 21 are respectively an air inlet end and an air outlet end. The air inlet end of the air blowing through hole 21 is provided with an air blowing system 3. The blowing system 3 is made of a blower or an air pump to ventilate the blowing through hole 21 so that the air circulates and leaves the blowing through hole 21 from the air outlet end. The width of the air outlet end of the air blowing through hole 21 is gradually reduced along the direction far away from the air blowing system 3, so that air is accelerated to generate an air injection effect when the air is separated from the air blowing through hole 21, and the waste cleaning effect of the automatic waste cleaning structure is improved.
Further, the lower side of the die-cutting rule 2 is provided with at least one waste inlet through hole 22 for communicating the air blowing through hole 21, and the axis of the waste inlet through hole 22 is arranged along the vertical direction. The waste inlet through hole 22 is positioned at one side of the cutting position between the die-cutting rule 2 and the adhesive film. The end of the waste inlet through hole 22, which is positioned on the outer wall of the die-cutting rule 2, is a waste inlet end, and the end of the waste inlet through hole 22, which is connected with the air blowing through hole 21, is a waste outlet end.
Further, the inner wall of the blowing through hole 21 is provided with a sealing gasket 26 around the opening of the waste inlet through hole 22, and the inner wall of the blowing through hole 21 is hinged with an opening and closing cover plate 23 which is used for abutting against or separating from the sealing gasket 26 to control the opening and closing of the waste outlet end of the waste inlet through hole 22. The number of the opening and closing cover plates 23 is the same as that of the waste inlet through holes 22. Specifically, one side of the opening and closing cover plate 23 close to the blowing system 3 is fixedly provided with a hinge shaft 231, and the axis of the hinge shaft 231 is arranged along the horizontal direction. A shaft seat 211 hinged with the hinge shaft 231 is fixedly provided on the inner wall of the blowing through hole 21.
The shaft seat 211 is located at the outer side of the sealing gasket 26, and the sealing gasket 26 is located at one side of the opening and closing cover plate 23 close to the waste inlet through hole 22.
The hinge shaft 231 is sleeved with a reset elastic member 25, and the reset elastic member 25 provides elastic force for rotating the opening and closing cover plate 23 towards the direction close to the waste inlet through hole 22. Preferably, the return elastic member 25 is a coil spring.
Further, one side of the opening and closing cover plate 23 facing the waste inlet through hole 22 is provided with an elastic pushing piece 24 penetrating out of the waste inlet through hole 22. One end of the elastic pushing and opening piece 24 is fixedly connected with the opening and closing cover plate 23, and the other end of the elastic pushing and opening piece 24 is fixedly provided with a friction gasket 27. The friction gasket 27 increases the friction between the elastic pushing and opening piece 24 and the cutting table 1, and avoids the sliding failure of the elastic pushing and opening piece 24.
