Abstract
The utility model relates to super high molecular weight polyethylene extrusion apparatus composed of a charging inlet, a screw rod, a charging barrel, a charging barrel heating device, etc. A shoving sleeve barrel is added on the outer wall of the charging barrel. The end of the charging barrel is designed into a melting stock cavity to enlarge material pressure. The polyethylene materials enlarge molecular weight and density through the apparatus.
Description
The utility model is a kind of ultra-high molecular weight polyethylene extrusion device that is used for injection molding machinery.
Along with the development of society, the plastic industry with wide market become and people's daily life between must an indispensable bridge block.Current, plastic products technology just towards efficiently, at a high speed, the direction of energy-conservation, high accuracy and maximization develops, plastic products industry has become a new industry department, its working ability has exceeded the production capacity of plastics, the plastic product forming technology causes people's attention day by day, how to improve the quality of plastic products, reduce bubble, scar in the goods, need the technical staff in the effort of getting on of the density of material and process equipment.
The present utility model forms a kind of ultra-high molecular weight polyethylene extrusion device in order to increase the improvement that plastics (polyethylene) molecular weight carries out existing device.
The PEF extruder in prior art field has two kinds of single screw rod and twin-screws, plastics (polythene material) are sent into from feeding mouth, after the screw rod extruding, deliver to forming machine, and this kind extruder all adopts directly to be pushed by screw rod and expects to head, if the molecular weight density of raising material, the high molecular weight material of thickness can't be pushed out body, thereby the extruder in the prior art has limited the molecular weight density that improves material.
Goal of the invention of the present utility model provides a kind of ultra-high molecular weight polyethylene extrusion device.
The purpose of this utility model is achieved in that the utility model partly is made up of motor, transmission device, hopper cooling device, barrel, barrel heater and screw rod etc., outer wall at barrel is provided with a pusher sleeve, be provided with oil pressure cylinder at the pusher sleeve ends, in barrel, set up molten material chamber under the loudspeaker; This discharging end, melt chamber is gradually thin shape, like this by gradually thin melt chamber, material is pressurizeed once more, to add macromolecule density, simultaneously by with the oil pressure cylinder being the pusher sleeve of power, material is extruded from the melt chamber smoothly, made extruder can extrude the polythene material that density is higher, molecular weight is bigger smoothly.
Be described further as follows below in conjunction with accompanying drawing to detailed structure of the present utility model, application principle:
Fig. 1 is the extruder schematic diagram of the utility model prior art.
Fig. 2 is an embodiment schematic diagram of the present utility model.
Please referring to accompanying drawing 1, single screw extrusion machine in the prior art, when polythene material from hopper 4 via hopper cooling device 5, deliver to then in the barrel 6, polythene material is squeezed into semi liquid state via the rotation of screw rod 9 in barrel 6, in order to make material can keep certain temperature, be provided with heater around the barrel, extrudate is the linear fashion motion of pressing screw rod 9 substantially, if strengthen the power of transmission device for the molecular weight density that improves material merely, can produce the explosion of barrel and the obstruction of screen pack and porous plate.The utility model is in order to change the deficiency that exists in the prior art.
Please referring to accompanying drawing 2, be designed to the melt chamber 7 of loud-speaker shape in the termination of barrel 6, the not end in melt chamber 7 attenuates material can be pressurizeed once more, in order to solve the discharging difficulty, the inventor increases pusher sleeve 61 at the outer wall of barrel 6, this pusher sleeve 61 is to do power by oil cylinder 15, assists and will deliver to the bottom operation through screw rod extruding and the ultra high molecular weight polyethylene material after molten material chamber 7 is pushed once more.
The inventor's that this extrusion device after the improvement reaches goal of the invention, the polythene material after extruding has increased molecular weight density, and has effectively solved the defective that the too high and existing extruder of density can not push.
