Description
Technical field
The invention belongs to the production technical fields of PC foaming plates, concretely relate to a kind of luggage PC foaming plates
Process units.
Background technology
Currently, the quality of plastic plate used by Bag-making industry, weight, price etc. are all higher, PC foaming plates were both protected
The high-intensity performance of PC plate material, the characteristics such as fire-retardant, bright in colour have been held, and have reduced the weight of plank, still, production hair at present
The method for steeping PC plate material mainly uses chemical blowing method, i.e., a certain proportion of foaming agent, auxiliary agent etc. are added in plastic raw materials,
In extrusion, when reaching the temperature of foaming agent, achieve the purpose that foaming, this method can bring a system by the gas decomposed
The problem of row：First, because of the reasons such as the dispersion of foaming agent is uneven or makes moist so that foam hole size is uneven, and distribution is uneven
It is even, the intensity of plank was not only influenced, but also influence the beauty of plate surface；Secondly, because foaming agent can not possibly be in an extrusion molding
Decomposed completely in journey, remaining foaming agent can the random foaming again in plastics sucking moulding and edge strip reuse, seriously affect production
The quality of product；Again, understand the decomposition gas overflowing of foaming agent or auxiliary agent and influence air environment and remained in plank in distress
The smell of news.
Invention content
The object of the present invention is to provide a kind of luggage process units of PC foaming plates, are measured using pressure maintaining valve and first
The duplex system of pump can accurately control the gas conveying capacity of gas nozzle, to accurately control the stability, continuity and foaming of foaming
Multiplying power makes foaming body exquisiteness, uniform, microcellular structure using capillary type gas nozzle, it is ensured that product strength is high, appearance is good, with more
The single screw rod of section mixing formation, has larger draw ratio and compression ratio so that PC materials are fully plasticized, eliminate fisheye, can be into
One step improves the abscess quality and intensity of foaming body.
In order to solve the above technical problems, the object of the present invention is achieved like this：A kind of life of luggage PC foaming plates
Device is produced, including extruder, distributor, mouth mold, setting roll, dragger, cutter, the extruded machine of raw material are squeezed out to distributor,
It is distributed to mouth mold by distributor, then is entered after setting roll sizing by mouth mold and be made into through drawing machine travel to cutter shear treatment
Product, extruder include machine barrel, are equipped with screw rod in machine barrel, machine barrel be equipped with can in machine barrel conveying gas gas nozzle, which is hair
Thin-tube type ventilation nozzle, gas nozzle connect pressure maintaining valve, and pressure maintaining valve connects the first metering pump, and the first metering pump is connected for being supplied to gas nozzle
External air source, external air source is pure gas.
The pure gas is the gas of poor activity, such as inert gas as a preferred embodiment of the above solution,.
As a preferred embodiment of the above solution, the screw rod for no mixing formation single screw rod.
The screw rod is the single screw rod with mixing formation as a preferred embodiment of the above solution,.
The screw rod is with one section of mixing formation or with two-stage mixing structure or tool as a preferred embodiment of the above solution,
There is the single screw rod of three-stage mixing structure.
The draw ratio of screw rod is 30-40 as a preferred embodiment of the above solution,:1.
Further include net-changing device and/or the second metering pump as a preferred embodiment of the above solution, raw material is squeezed out by extruder to draping
It is squeezed out again after device and/or the second metering pump to the distributor.
The present invention is beneficial to be had the technical effect that：1）Compared with traditional technology, produced using process units provided by the invention
Expanded material have quality it is lighter, intensity higher, appearance and abscess quality more preferably the characteristics of, the present invention use physical blowing
Method, without increasing foaming agent in production process, can save when production cost, plastics sucking moulding and production generated waste product and
Edge strip etc. can be recycled all, and not interfere with the quality of product, when production, nonhazardous gas discharge, and environmental protection.
2）The gas conveying capacity of gas nozzle can be accurately controlled using the duplex system of pressure maintaining valve and the first metering pump, to accurate
Control stability, continuity and the expansion ratio of foaming.
3）Using capillary type gas nozzle, make foaming body exquisiteness, uniform, microcellular structure, it is ensured that product strength is high, appearance is good.
4）Single screw rod with multistage mixing formation has larger draw ratio and compression ratio so that PC materials are fully moulded
Change, eliminate fisheye, can further improve the abscess quality and intensity of foaming body.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
In figure：1, heating collar, 2, machine barrel, 3, cooling blower, the 4, first metering pump, 5, pressure maintaining valve, 6, screw rod, 7, draping
Device, the 8, second metering pump, 9, distributor, 10, mouth mold.
Specific implementation mode
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings, referring to Fig. 1；
A kind of process units of luggage PC foaming plates, including extruder, distributor, mouth mold, setting roll, dragger,
