Description
Technical field
The present invention relates to technical field of plastic, relate in particular to a kind of plastics-production line.
Background technology
The raw-material process of plastic product is for to enter into extruder by plastics materials from hopper, under the rotation of screw rod drives, it is carried forward, material is in proal process, accept the heating of barrel, shearing and the compression that screw rod brings makes material melting, thereby realized the variation between the tri-state of glassy state, elastomeric state and viscous state.
In the situation of pressurizeing, make material in viscous state by thering is the mouth mould of certain shape, then become cross section and mouthful similar non-individual body of apperance according to mouth mould.Then cooling and shaping forms glassy state, carries out bailing and then carries out following process.
That plastic product carries out after being extruded by extruder is cooling, dry, material need to draw in the process of cutting, can move according to both fixed tracks to guarantee that material leaves after plastics-production line, in traditional plastics-production line, draw-gear and extrusion system are to control separately, both speeds of service are difficult to keep in balance, in the time that the too fast and hauling speed of extruded velocity is relatively slow, can cause material stacking, if and the too fast extruded velocity of hauling speed is crossed when slow and material can be stretched and cause deformation of products, even product may be broken.Therefore a kind of plastics-production line that can keep material tensile force is provided is very important in the art research topic.
In plastics-production process, often can produce in addition pernicious gas, above-mentioned gas can cause damage to health to environment simultaneously.
Summary of the invention
