Abstract
The invention relates to a method for forming plastic imitated grass or plastic imitated vines. The method comprises the following steps of: uncoiling single piece or multiple pieces of plastic silks or films through an uncoiling device, applying tension to the plastic silks or films through a tensioning device, threading the plastic silks or films into a die with holes of fixed size, heating the die, pulling the plastic silks or films out of the holes of the die by using a drafting machine after heating is finished, cooling the plastic silks or films, and finally, coiling the plastic silks or films by using a coiling machine or directly cutting the plastic silks or films to the required length. By the method, the prepared plastic imitated grass or plastic imitated vines have skin core structures and elasticity, the colors of the plastic imitated grass or the plastic imitated vines are changed together with change of the plastic silks or films, and the plastic imitated grass or the plastic imitated vines can be rich and colorful.
Description
Technical field
The present invention relates to plastics grass technical field, particularly relate to a kind of forming method of plastics grass.
Background technology
The life requirement that becomes increasingly abundant along with modern people, the kind of required various ornament materials and daily necessities etc. also becomes increasingly abundant, because restrictions such as pure natural materials service life, corrosion-resistant, wear-resisting, waterproof, processing technology, in a lot, can not satisfy people to the processing of these materials and the demand of aesthetic.
Summary of the invention
Technical problem to be solved by this invention provides a kind of forming method of plastics grass, makes the plastics grass that makes have skin-core structure.
The technical solution adopted for the present invention to solve the technical problems is: the forming method that a kind of plastics grass is provided, may further comprise the steps: at first wall scroll or many plastics silks or film are unreeled by a unwinding device, give tension force by a tensioner again, penetrate then in the mould that has a fixed size eyelet, and described mould heated, heating utilizes after finishing drafting machine that described plastics silk or the film eyelet lira from described mould is gone out, then imitative grass of the plastics of moulding or the imitative rattan of plastics are cooled off, utilize at last the winder rolling get up or directly segment become desired length.
When using many plastics silks or film, described each bar plastics silk or film mix the plastics silk or the film of working it out for adopting one or more materials.
When using many plastics silks or film, each bar plastics silk in the middle of described being placed on or film adopt different materials with each bar plastics silk that is placed on the outside or film.
The scope that described tensioner gives tension force is 1~50N.
Described heating-up temperature to mould is 90~300 ℃.
The draw rate of described drafting machine is 1~100m/min, and the pulling force size is 1~350N.
The eyelet of described mould is square, circular, semicircle, ellipse or triangle.
The described mode that plastics silk or film are cooled off is air cooling or water-cooled.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: the present invention is by a heating mould, the surface of plastics silk is merged, and the inside of coating plastic silk, make that only heal in the surface, but plastics silk internal material is injury-free, thereby make the plastics grass of producing have skin-core structure, the temperature of control heating mould and the speed by heating mould, the thickness of cortex can be controlled, thereby various flexible plastics grass can be produced.
The present invention uses the plastics heating and melting, cool off and the characteristics of hardening, the plastics silk is passed through in the heated mold, contact with the inner surface of die hole, thereby the plastics silk is melted in the face of mould contact, the plastics silk that can not contact with mould then keeps original state, after rapid cooling, just forms the plastics grass of intact skin-core structure.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The present invention relates to a kind of forming method of plastics grass, this method is by a heating mould, the surface of plastics silk is merged, and the inside of coating plastic silk make that only heal in the surface, but plastics silk internal material is injury-free, thereby make the plastics grass of producing have skin-core structure, the temperature of control heating mould and the speed by heating mould can be controlled the thickness of cortex, thereby can produce various flexible plastics grass.
Technological process of the present invention as shown in Figure 1.At first wall scroll or many plastics silks or film are unreeled by a unwinding device 1, give tension force by a tensioner 2 again, the scope that gives tension force is 1~50N, penetrate then in the mould 3 that has a fixed size eyelet, and described mould 3 heated, the temperature range of heating is 90~300 ℃, heating utilizes after finishing drafting machine 4 that described plastics silk or the film eyelet lira from described mould is gone out, the draw rate of drafting machine is 1~100m/min, the pulling force size is 1~350N, and in the process of pulling out, utilize 5 pairs of plastics silks of cooler or film to cool off, the type of cooling of this cooler can be the air cooling, can be water-cooled also, and utilize winder 6 rollings get up or directly segment become desired length.
Need to prove that when using many plastics silks or film, described each bar plastics silk or film can adopt identical materials, also can adopt different materials.When using different materials, preferably make each bar plastics silk or film in the middle of being placed on adopt different materials with each bar plastics silk that is placed on the outside or film, that is to say, each bar plastics silk or film in the middle of being placed on are with a kind of, as HDPE material or the material that uses two or more materials to mix, each the bar plastics silk or the film that are placed on the outside are another kind of material, as PE material or the material that uses two or more materials to mix.In a word, as long as each middle bar plastics silk or film use different materials with each the bar plastics silk or the film in the outside.So can change other performances such as the elasticity of imitative grass of plastics or the imitative rattan of plastics and water imbibition by core in the middle of changing.
Described mould can adopt the mould of cylinder-like structure, and eyelet can be square, circular, triangle, semicircle, ellipse or other geometry on the mould, can make the cross sectional shape difference of the imitative grass of plastics, the imitative rattan of plastics by the shape that changes eyelet.The plastics silk that adopts or the color difference of film also can so that to the imitative grass of plastics, the imitative rattan of plastics different colors is arranged.
The present invention utilizes the hot formability of plastics, with one or more plastics silk or film, after mixing, obligate in an eyelet, give certain force of strain before and after the eyelet, and this eyelet is heated to the temperature of this plastic shaping, the control plastics are by the speed of eyelet, imitative grass of the plastics of last cooling forming rapidly or the imitative rattan of plastics, the plastics grass that this method is produced has kept the characteristic of original plastics, and the speed of control plastics by eyelet, can the imitative grass of these plastics or the imitative rattan epidermis of plastics merge intact, and the centre is without damage, thereby makes this plastics grass high resilience.
