Abstract
The invention discloses an ultrasound feeding device of a single-screw for machining wood-plastic materials. The ultrasound feeding device comprises an ultrasound device and a forced feeding screw rod (5) and is characterized in that the ultrasound device consists of a power supply (1), a transducer (2) and a variable-amplitude rod (3), the variable-amplitude rod (3) is connected with the forced feeding screw rod (5), the forced feeding screw rod (5) is mounted in the hopper (4), and rotates along the axial direction and vibrates upwards and downwards under the action of ultrasound, the hopper (4) is mounted on a shell body (6), and a screw rod (7) of the extruder is mounted in the shell body (6). The ultrasound feeding device is beneficial to the thorough mixing of a plastic matrix and filler, the generation of bubble defects is reduced, and the quality of the wood-plastic materials is improved.
Description
Technical field
The present invention relates to a kind of single screw extrusion machine feeding device for Wood-plastic material processing, relate in particular to a kind of ultrasonic feeding device.
Background technology
Wood plastic composite has the double grading of timber and plastics concurrently, and it has the outward appearance of natural timber, and simultaneously, its anticorrosion, not yielding, good mechanical property has the advantages such as hard, lasting, wear-resisting.The main forming method that adopts in its suitability for industrialized production at present has: extrusion molding, injection moulding and hot-forming.Short due to the extrusion molding process-cycle, efficient is high, moulding process is simple, compared with other processing method in suitability for industrialized production widely and to have used.Single screw extrusion machine is mainly adopted in extrusion molding; be powder because the wood fibre that adds is most of; be difficult for the extruder screw feeding and the wood powder structure is fluffy; join in extruder between plastic substrate and inserts simultaneously, so " bridge formation " and " pole " phenomenon usually can occur in reinforced process with can not forming desirable mixture and uniformity.When particularly containing more moisture in wood powder, this phenomenon is more obvious.Reinforced unstablely not only directly cause extruding yielding poorly, also can make and extrude fluctuation, cause and extrude quality and reduce.Simultaneously, interrupt due to reinforced, material time of staying prolongation in machine barrel causes material to burn variable color, affects inherent quality and the outward appearance of goods.Therefore must do strict control to feed way and feeding quantity, the general employing forced feeding device and hungry feeding, and be stable with what guarantee to extrude.But force feeding device can only guarantee that in reinforced process, material does not interrupt, mix inhomogeneous problem and can not solve between plastic substrate and inserts.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of ultrasonic feeding device of single screw extrusion machine for Wood-plastic material processing, can either guarantee that in reinforced process, material does not interrupt, plastic substrate and inserts are mixed.
Technical scheme of the present invention is as follows:
A kind of ultrasonic feeding device of single screw extrusion machine for Wood-plastic material processing, comprise Vltrasonic device and force reinforced screw rod, it is characterized in that: Vltrasonic device is comprised of power supply, transducer and ultrasonic transformer, ultrasonic transformer is connected with forcing reinforced screw rod, force reinforced screw rod to be arranged in hopper, force reinforced screw rod 5 along the axis direction rotation and under ultrasonication up-down vibration, hopper is arranged on housing, extruder screw is arranged in housing.
The vibration amplitude of Vltrasonic device is 10～12
, vibration frequency is 20～25
The present invention adds ultrasonic vibration on the reinforced screw rod of common pressure, to produce following beneficial effect: after forcing reinforced screw rod to add ultrasonic vibration, can produce axial ultrasonic vibration in rotation, being conducive to plastic substrate fully mixes with inserts, avoid the existence of " bridge formation " and " pole " phenomenon, and ultrasonic vibration also helps the air of discharging in material, the existence of minimizing air blister defect.
Description of drawings
Fig. 1 is structure chart of the present invention.
The specific embodiment
The invention will be further described according to instantiation and accompanying drawing for the below:
As can be seen from Figure 1, the present invention includes Vltrasonic device and force reinforced screw rod, Vltrasonic device is comprised of power supply, transducer and ultrasonic transformer, ultrasonic transformer 3 is connected with transducer 2, transducer 2 is connected with power supply 1, and it is 20KHz that ultrasonic ultrasonic vibration frequency is set, and amplitude of ultrasonic vibration is 10
, with ultrasonic amplitude transformer 3 and force reinforced screw rod 5 to be connected, force reinforced screw rod 5 to be arranged in hopper 4, force reinforced screw rod 5 along axis direction rotate and under ultrasonication up-down vibration, hopper 4 is arranged on housing 6, extruder screw 7 is arranged in housing 6.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
