Description
Technical Field
The invention relates to the field of die-cut piece processing, in particular to a method for manufacturing a die-cut piece containing acetic acid cloth.
Background
The acetic acid cloth base material has strong moisture absorption and air permeability, good rebound resilience, easy washing and drying, no static electricity and hair bulb, and excellent aging resistance which 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 formability, easy punching, easy unwinding, acid, alkali and 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.
But also is often applied to the interlayer insulation of motors and transformers, especially high frequency transformers, microwave oven transformers, capacitors and variable frequency power adapters; winding and bundling a coil and a wire harness; fixing oven local parts, deflection coil ceramic chips, ceramic heaters and quartz tubes; is widely applied to television and monitor matching products.
In the process of manufacturing the acetic acid cloth-containing die-cutting piece, broken filaments on the acetic acid cloth are often brought out during waste discharge, so that the product is poor, manual trimming is required to be performed on the product at the subsequent stage, manpower is wasted, and efficiency is low.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for manufacturing a acetic acid-containing cloth die-cut piece, which does not form broken filaments on a product and has low product reject ratio.
The purpose of the invention can be realized by the following technical scheme:
because the weaving lines on the acetate cloth are often in a # -shape, the acetate cloth is difficult to be completely cut off like a common material belt during die cutting, when the waste discharge direction is nearly vertical to the side frame of the die cutting piece which firstly discharges waste, the waste discharge direction means that the waste discharge direction faces to a line, each fiber yarn to be torn is broken when the waste discharge is decomposed, the force for tearing the fiber yarns is generated, due to the toughness of the acetate cloth fiber yarns, the waste discharge tension is insufficient, the situation of 'hard tearing' can occur, irregular breakpoints, namely 'broken filaments', the broken filaments can be stuck to products, the defects of the products are formed, the products are poor, manual screening or trimming is needed in the later period, and the production efficiency is reduced rapidly.
The inventor knows that the waste discharge direction is perpendicular to the side frame of the die-cutting piece which discharges waste firstly, even the # -shaped weaving lines are nearly perpendicular, so the inventor tries to adjust the angle between the waste discharge direction and the side frame, and after a plurality of experiments, the following specific scheme is obtained:
a manufacturing method of a die-cut piece containing acetate cloth, wherein the acetate cloth comprises well-shaped woven grains which are arranged alternately in a horizontal direction and a vertical direction, and the method comprises the following steps:
(1) laminating in one-level material area: sequentially attaching the release film and the acetic acid cloth on the protective film to form a first-grade material belt;
(2) a die cutting and waste discharge: carrying out first stamping and die cutting on the primary material belt in a stamping and die cutting machine, and discharging first stamping waste materials to form a secondary material belt;
(3) secondary die cutting and waste discharge: carrying out secondary punching die cutting on the secondary material belt in a secondary die cutting machine, discharging secondary punching waste materials, and forming a finished product of the acetic acid cloth-containing die cutting piece, wherein the secondary die cutting machine is provided with a knife line b matched with a secondary die cutting pattern, and the knife line b comprises a knife line b forming an included angle of 30-60 degrees with the running direction of the material belt3The knife line b3Is positioned at the side which is firstly discharged; the included angle can not be too large or too small, and if the included angle is 0-30 degrees or 60-90 degrees with the running direction of the material belt, the edge of the product is still nearly vertical to the running direction of the material belt, so that the problem can not be fundamentally solved.
(4) Rolling a die-cut product: and rolling the finished product of the acetic acid-containing cloth die-cut piece.
Furthermore, a cutting line a matched with a cutting pattern of the die is arranged on the die cutting machine, and the cutting level of the cutting line a is acetic acid cloth.
Furthermore, the knife line a comprises the knife lines a which are connected in sequence1Knife line a2And the knife line a3The cutting line a2And forms an included angle of 30-60 degrees with the running direction of the material belt.
Furthermore, the punching waste comprises side line waste punched by the acetate cloth.
Furthermore, the punching layers of the knife line b sequentially comprise acetic acid cloth and a release film from top to bottom.
Furthermore, the knife line b comprises knife lines b which are sequentially sealed and connected1Knife line b2Knife line b3And the cutting line b4The cutting line b1And/or cutting line b3In the direction of the material beltAnd the included angle is 30-60 degrees.
Further, the secondary punching waste comprises acetic acid cloth and frame waste punched by a release film.
Further, the knife line a2The included angle between the cutting line and the running direction of the material belt is 30 degrees, and the cutting line a1And the knife line a3And forms an included angle of 60 degrees with the running direction of the material belt. The knife line b1And the cutting line b3An included angle of 60 degrees is formed between the cutting line b and the running direction of the material belt2And the cutting line b4And forms an included angle of 30 degrees with the running direction of the material belt.
Taking this case as an example, after the cross cutting, because the cross cutting piece first row of giving up a side frame and the material area traffic direction formed certain angle, when having led to giving up, at first the facing is a point, rather than a line, the condition of stress concentration can appear for the cellosilk is broken by the snap fast very easily, along with the continuation of giving up, the phenomenon of stress concentration can continue to wave remaining part, just so can not have a complete cellosilk to hang at the product edge, because when giving up, can not leave over irregular breakpoint.
A sheet die-cut member comprising an acetate cloth manufactured as described above with reference to fig. 7 to 8. Tests show that the manufactured product is inclined, the waste discharge force can be increased by utilizing the concept of stress concentration, so that broken filaments can not be formed, and the defects of the broken filaments of the product are overcome.
Compared with the prior art, the invention has the following advantages:
(1) after die cutting, because a certain angle is formed between the frame at the waste discharge side and the running direction of the material belt, the fiber yarns on the edge are easily and quickly broken, and no wool yarns are hung on the edge of the product;
(2) by adopting the technology of the invention, the problem of broken filaments is solved, and the broken filaments do not need to be trimmed manually, thereby improving the productivity, reducing the labor and improving the qualification rate of products.
