Description
Technical field
The present invention relates to a kind of plank production technology of moulding, relate in particular to intensity height in, production efficiency high mould the plank production technology.
Background technology
Mould plank and have texture two specific characters of the water-fast anticorrosion and timber of plastics concurrently; applying of it can be saved a large amount of natural timbers; be conducive to preserve the ecological environment; simultaneously because the composition of natural fiber has been arranged; moulding plank has better anti-ultraviolet property and the lower performance of expanding with heat and contract with cold, and is easy to processing as timber.Moulding plank is that the employing string is main material, processes synthetic composite with plastics.Existing processing will mould that plank is synthetic to carry out with cutting to separate, the production efficiency that slowed down like this, and Jia Gong the plank intensity of moulding is not very high simultaneously.
Summary of the invention
Technical problem to be solved by this invention provide a kind of production to mould plank intensity higher and production efficiency is high moulds the plank production technology.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of plank production technology of moulding is characterized in that comprising following steps:
A, will mould the plank raw material and uninterruptedly feed in raw material by the uninterrupted charging system that is made of two feeding devices, and then raw material be mixed by mixer, mixer adopts centering type to mix rotational velocity 40-60r/min, revolution speed 1-2r/min;
B, the raw material that mixes is undertaken extruding for twice by two extruders that link together, and the two extruders Heating Zone Temperature is arranged on 160-220 ℃, then the raw material extruded is obtained the preliminary plank blank of moulding by mould discharging, heating-up temperature is arranged on 160-220 ℃ in the mould, and the grinding tool temperature equals or is slightly larger than extruder temperature;
C, the plank of moulding that comes out from mould are pressed into reinforcing mat and enclose thin film in the upper and lower surface of moulding plank at calender, then by the calendering formation of calender and by obtaining moulding the plank finished product after the cooling, calender calendering wheel separated into two parts, the liquid that preceding part feeding is 180-220 ℃ heats, and a back part is rolled wheel feeding cooling fluid and cooled to moulding plank;
D, carry out cutting of online fabric width and length to moulding plank finished product specification size as required, at last the packing warehouse-in.
Further, the compression distance of reinforcing mat is 1.5-2.5mm among the described step C.
Further, film adopts acid-proof alkali prevention antiultraviolet and fire-retardant macromolecule membrane among the described step C.
Adopt above-mentioned technical scheme, the plank production technology of moulding of the present invention is produced continuously by uninterrupted feeding in raw material, and has improved production efficiency; Simultaneously with the calendering of calender wheel separated into two parts, preceding part heating, back part cooling has improved the intensity of moulding after the plank moulding like this; Carry out online cutting to moulding plank at last, guaranteed the continuity of producing, improved production efficiency.Combination by the way, of the present invention mould that the plank production technology produces to mould plank intensity higher and production efficiency is high.
Description of drawings
Fig. 1 is a kind of production line front view of moulding the plank production technology of the present invention.
Fig. 2 is a kind of production line vertical view of moulding the plank production technology of the present invention.
The specific embodiment
As Fig. 1 or shown in Figure 2, a kind of plank production technology of moulding of the present invention mainly comprises following steps:
A, at first will mould the plank raw material and uninterruptedly feed in raw material by the uninterrupted charging system that is constituted by two feeding devices; by sensor the raw material condition in the feeding device is monitored; another feeding device that automaticallyes switch when raw material uses up feeds in raw material; need not shut down like this and feed in raw material, improve production efficiency.Then raw material is mixed by mixer, mixer adopts centering type to mix, rotational velocity 40-60r/min, revolution speed 1-2r/min, mixer by centering type, improved the effect of mixing, prepared by the mixed material of string and plastics being mixed for next step extrusion forming.
B, the raw material that mixes is undertaken extruding for twice by two extruders that link together, and the two extruders Heating Zone Temperature is arranged on 160-220 ℃, then the raw material extruded is obtained the preliminary plank blank of moulding by mould discharging, heating-up temperature is arranged on 160-220 ℃ in the mould, and the grinding tool temperature equals or is slightly larger than extruder temperature.Process moulding the plank raw material by two extruders like this, it is more thorough to have guaranteed to mould plank processing like this, improves the quality of finally moulding board products, by the mould molding ejecting plate, simple and practical at last, the production efficiency height.
C, the plank of moulding that comes out from mould are pressed into reinforcing mat and enclose thin film in the upper and lower surface of moulding plank at calender; reinforcing mat compression distance 1.5-2.5mm; strengthen the intensity mould plank by reinforcing mat; and adopt acid-proof alkali prevention antiultraviolet and fire-retardant macromolecule membrane to pass through the prevention on surface like this; protection is moulded plank and can be corroded; improved the service life of moulding plank, the flame resistance of also having strengthened moulding plank has simultaneously improved security.Afterwards again on the calender by the calendering formation of calender and by obtaining moulding the plank finished product after the cooling, calender calendering wheel separated into two parts, the liquid that preceding part feeding is 180-220 ℃ heats, and a back part is rolled wheel feeding cooling fluid and cooled to moulding plank.Process moulding plank respectively by two-part calendering wheel like this, in first the calendering wheel is heated, make like this and be pressed into reinforcing mat and overlay film is more easy, and it is convenient to moulding the calendering of plank, better effects if, calendering by second portion wheel cools off again, has guaranteed to mould the intensity after the plank moulding like this, has improved the integral intensity of moulding plank.
D, carry out cutting of online fabric width and length to moulding plank finished product specification size as required, by online cutting, guaranteed the continuity of whole production line, improved and moulded the efficient that plank is produced, at last the packing warehouse-in.
By above-mentioned technical scheme, the plank production technology of moulding of the present invention is moulded the raw material adding in the plank production equipment by uninterrupted charging system, uninterruptedly feed in raw material in turn by two feeding devices like this, save the time of reloading, guaranteed the continuity of producing, improved production efficiency; Process by two extruders again, improved product quality, and calender calendering wheel separated into two parts, preceding part heating, back part cooling has improved the effect of calendering, the bulk strength performance of having strengthened moulding plank simultaneously like this; Cut moulding plank according to required specification size by online transverse cutting unit and length sawing after moulding the plank moulding, like this by online cutting, guaranteed the continuity of producing, improved greatly and moulded the efficient that plank is produced.By the combination of technique scheme, of the present invention mould that the plank production technology produces mould plank intensity height, quality is good and production efficiency is high.
