Description
Technical Field
The invention relates to the field of die-cutting piece processing, in particular to a manufacturing method of a die-cutting piece containing acetate cloth.
Background
The acetate cloth base material has strong moisture absorption and ventilation capability, good rebound resilience, easy washing and drying, no static electricity and hair bulb, and excellent aging resistance, and can reach more than 15 years. Meanwhile, the acetate cloth adhesive tape processed by the acetate cloth base material has the characteristics of high temperature resistance, ageing resistance, softness, good shape, easy punching, easy unwinding, acid resistance, alkali resistance, mildew resistance and the like, has better insulating property than common glass fiber cloth and glass cloth, and is widely applied to the manufacturing fields of televisions, transformers, air conditioners, computers and the like.
The insulating material is often applied to interlayer insulation of motors and transformers, in particular to high-frequency transformers, microwave oven transformers, capacitors and variable-frequency power adapters; winding and bundling the coil and the wire harness; the oven local parts, the deflection coil ceramic chip, the ceramic heater and the quartz tube are fixed; the method is widely applied to television and monitor matching products.
In the process of manufacturing the die-cut piece containing the acetate cloth, the broken filaments on the acetate cloth are often brought out when waste is discharged, so that the product is poor, the product needs to be manually trimmed later, labor is wasted, and the efficiency is low.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a manufacturing method of a die-cut piece containing acetate cloth, which can not form broken filaments on products and has low product reject ratio.
The aim of the invention can be achieved by the following technical scheme:
Because the weaving lines on the acetate cloth are often groined, the acetate cloth is difficult to cut off completely like a common material belt when die-cut, when the waste discharge direction is nearly vertical to the side frame of the die-cut piece, which means that the waste discharge direction is opposite to that of a line when waste discharge, each fiber yarn to be torn breaks down the force of breaking the fiber yarn when waste discharge, and the situation of hard tearing can occur due to insufficient waste discharge tension caused by the toughness of the acetate cloth fiber yarn, so that irregular break points, namely 'broken yarn', are formed, the broken yarn can be adhered to a product, the defect of the product is formed, the bad product is all caused, and manual screening or trimming is needed in the later stage, so that the production efficiency is rapidly reduced.
The inventor knows that the situation of the defect is that the waste discharge direction is vertical to the side frame of the die-cutting piece, even the phenomenon that the waste discharge direction is nearly vertical to the side frame of the die-cutting piece, and the inventor tries to adjust the angle between the waste discharge direction and the side frame of the die-cutting piece, and after a plurality of tests, the inventor obtains the following specific scheme:
the manufacturing method of the die-cut piece containing the acetate cloth comprises the steps of:
(1) Laminating of first-stage material belt: sequentially attaching the release film and the acetate cloth on the protective film to form a first-stage material belt;
(2) A die cuts and discharges waste: carrying out one-shot die cutting on the primary material belt in one-shot die cutting machine, and discharging one-shot waste material to form a secondary material belt;
(3) Cutting and discharging waste by a secondary die: carrying out secondary punching die cutting on the secondary material belt in a secondary punching die cutting machine, discharging secondary waste materials to form a finished product containing acetate cloth die cutting pieces, wherein a cutter line b matched with a secondary punching die cutting pattern is arranged on the secondary punching die cutting machine, the cutter line b comprises a cutter line b 3 which forms an included angle of 30-60 degrees with the running direction of the material belt, and the cutter line b 3 is positioned on one side of waste discharge firstly; the included angle cannot be too large or too small, and if the product edge is in a nearly vertical state with the material belt running direction when the product edge is in 0-30 degrees or 60-90 degrees with the material belt running direction, the problem cannot be fundamentally solved.
(4) And (3) rolling a die cutting piece product: and rolling the finished product of the acetate-containing cloth die-cut piece.
Further, a knife line a matched with a die cutting pattern is arranged on the die cutting machine, and the die cutting layer of the knife line a is acetate cloth.
Further, the knife line a comprises a knife line a 1, a knife line a 2 and a knife line a 3 which are sequentially connected, and the knife line a 2 forms an included angle of 30-60 degrees with the running direction of the material belt.
Further, the waste punching material comprises edge line waste material obtained by punching the acetate cloth.
Further, the punching layer of the knife line b sequentially comprises acetate cloth and a release film from top to bottom.
Further, the knife line b comprises a knife line b 1, a knife line b 2, a knife line b 3 and a knife line b 4 which are sequentially and closely connected, and the knife line b 1 and/or the knife line b 3 form an included angle of 30-60 degrees with the running direction of the material belt.
Further, the secondary punching waste comprises acetate cloth and frame waste obtained by punching the release film.
Further, the knife line a 2 forms an included angle of 30 degrees with the running direction of the material belt, and the knife line a 1 and the knife line a 3 form an included angle of 60 degrees with the running direction of the material belt. Knife line b 1 and knife line b 3 form an included angle of 60 degrees with the running direction of the material belt, and knife line b 2 and knife line b 4 form an included angle of 30 degrees with the running direction of the material belt.
Taking this case as an example, after die cutting, because the die cutting piece is discharged at first and has formed certain angle with the material area direction of operation of one side frame, when having led to discharging, first facing is a point, but not a line, the condition that stress concentration can appear for the cellosilk is broken fast very easily, along with the continuation of discharging, stress concentration's phenomenon can continue to sweep remaining part, just so do not have a complete cellosilk to hang at the product edge, because when discharging, can not leave over irregular breakpoint.
A cut comprising acetate cloth made by the method described above with reference to figures 7-8. Through tests, the manufactured product is inclined, and the waste discharge force can be increased by utilizing the concept of stress concentration, so that the broken filaments are not formed, and the defect generated by the broken filaments of the product is solved.
Compared with the prior art, the invention has the following advantages:
(1) After die cutting, as the frame on the waste discharge side and the running direction of the material belt form a certain angle, the fiber on the edge is easily and rapidly broken, and no broken filaments are hung on the edge of the product;
(2) By adopting the technology of the invention, the problem of broken filaments is solved, and broken filaments do not need to be manually trimmed, thereby improving the productivity, reducing the labor and improving the qualification rate of products.
