With the present invention, the glass fiber cutting device is the independent device, such that the abrasion of the glass fiber is avoided; one or plural groups of modules can be freely arranged by the machine group according to the requirement; the structures of the whole machine group are simple, the arrangement is flexible, and the production investment cost is low.
Description
Technical field
The present invention relates to direct method long fiber reinforced thermoplastic composites on-line machining production line.
Background technology
Long fiber thermoplastic composite (LFT) is the exploitation focus of current external thermoplastic composite, has characteristics such as high-strength light, environmental protection be recyclable, is widely used in automobile, electrical equipment, track traffic, building trade and civilian, light industry field.
The German Ke BeilongW &P of mainly containing of a whole set of long fiber reinforced thermoplastic composites direct-on-line processing (LFT-D) production line can be provided the D-LFT system production line of company at present, the LFT-D-ILC production line of German Dieffenbacher (Dieffenbacher) company etc.The compound of the cut-out of above-mentioned production line glass fibre, dispersion and glass and polymer all is in screw extruder, to carry out, and the problem of bringing thus is: the length of glass receives the restriction of screw pitch, generally can only reach about 20mm ~ 25mm.Because screw rod to the wearing and tearing of glass, causes the performance of goods to reduce.The screw-rod structure relative fixed for the various performance requirement of product, needs to change different screw elements.Glass fibre is to the serious wear of screw element, and the product of every production some just need be changed the screw element of wearing and tearing, and production cost is high.
Summary of the invention
The object of the present invention is to provide a kind of long fiber reinforced thermoplastic composites direct-on-line process equipment, make every effort to realize longer glass length, better product properties, cheaper production input.
The present invention mainly is made up of screw extruder, sheet cutting machine, press, control system; Solve technical scheme that its technical problem adopts and be and adopt independently glass fibre to cut off dispersal device and constant temperature stainless steel conveyor belt independently, glass cuts off dispersal device to be made up of polyurethane backing roll and carbon steel rotor, is embedded with stainless steel blade on the rotor.Glass cut-out dispersal device, screw extruder are fixed on the front end of the parallel stainless steel conveyor belt of constant temperature, and outlet of extruder and glass outlet extend in the stay-warm case of constant temperature stainless steel conveyor belt.It is outside that stay-warm case is coated on whole piece constant temperature stainless steel band, and infrared heating device is set in the stay-warm case.Constant temperature stainless steel conveyor belt interlude is equipped with the stainless steel band calender, is fixed on directly over the constant temperature stainless steel through adjusting device, and adjusting device is made up of screwed adjusting screw(rod) and regulating handle.Calender is the roller belt-type structure, and it is outside that stainless steel conveyor belt is coated on hollow pressure roller.Constant temperature stainless steel conveyor belt afterbody is equipped with the sheet cutting machine, and this device is drum-type structure, and stainless steel blade is installed in around the cylinder.
The invention has the beneficial effects as follows: the wearing and tearing of glass have been avoided because glass is cut to self-contained unit in (1).Glass length can freely be confirmed according to arts demand, makes finished product have better performance.(2) unit can adopt the long stainless steel conveyor belt of a whole piece, also can adopt the short stainless steel conveyor belt combination of many groups, and modularization composite structure can freely be provided with one or more groups module as required.(3) the compound number of plies of glass and molten polymer, glass are arranged and all can freely be designed, and can make various thermoplastic sheets that can not performance requirement.(4) a whole set of set structure is simple, is provided with flexibly, has effectively reduced the production input cost.
