In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical problem adopted and is: a kind of extrusion molding feeding device comprises feeding device and continuous mixing arrangement; Said feeding device is provided with three, and said each feeding device comprises feed hopper and feeding pipeline, and an end of said feeding pipeline connects feed hopper; The other end of said feeding pipeline connects continuous mixing arrangement; Said feed hopper comprises bulk supply bucket and auxilliary feed hopper, and said auxilliary feed hopper is provided with two, is provided with three runners in the said continuous mixing arrangement; Be connected with three feeding pipelines respectively, said three runners converge in the exit of continuous mixing arrangement.
According to a preferred embodiment of the utility model, a kind of extrusion molding feeding device further comprises said three feeding devices, and circumference evenly distributes along continuous mixing arrangement bottom.
According to a preferred embodiment of the utility model, a kind of extrusion molding feeding device further comprises said runner shape in the shape of a spiral.
According to a preferred embodiment of the utility model, a kind of extrusion molding feeding device comprises that further said feeding pipeline set inside has spiral propeller.
According to a preferred embodiment of the utility model, a kind of extrusion molding feeding device comprises that further said continuous mixing arrangement is provided with the Material control device, is electric connection between said Material control device and the continuous mixing arrangement.
According to a preferred embodiment of the utility model, a kind of extrusion molding feeding device comprises that further said Material control device is provided with a plurality of displays.
The utility model has solved the defective that exists in the background technology; A kind of reasonable in design, compact conformation, easy to operate extrusion molding feeding device are provided; Are furnished with three feeding devices on this device; They have corresponding melt flow channel respectively, and the three-layer co-extruded plastic film thickness of producing like this is even, and the binding ability between each layer is strong.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiment of the utility model extrusion molding feeding device;
Fig. 2 is the structural representation of the feeding device of the utility model extrusion molding feeding device;
Fig. 3 is the structural representation of the continuous mixing arrangement of the utility model extrusion molding feeding device.
Wherein: 1, feeding device, 2, continuous mixing arrangement, 3, feed hopper, 4, feeding pipeline, 5, spiral propeller, 6, the Material control device, 7, display.
The specific embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
See also Fig. 1 to Fig. 3, a kind of extrusion molding feeding device that the utility model discloses comprises feeding device 1 and continuous mixing arrangement 2.Said feeding device 1 is set to three, and wherein each feeding device 1 comprises feed hopper 3 and feeding pipeline 4, and an end of said feeding pipeline 4 connects feed hopper 3, and the other end of said feeding pipeline 4 connects continuous mixing arrangement 2.Said feed hopper 3 comprises bulk supply bucket and auxilliary feed hopper, and said auxilliary feed hopper is provided with two, is provided with three runners in the said continuous mixing arrangement 2, is connected with three feeding pipelines 4 respectively, and said three runners converge in the exit of continuous mixing arrangement 2.
In the utility model extrusion molding feeding device, be provided with three feeding devices 1; It evenly distributes along the bottom circumference of continuous mixing arrangement 2 respectively; Be provided with three runners in the mixing arrangement 2 continuously; Said runner is shape in the shape of a spiral, and three runners are connected with three feeding pipelines 4 respectively, and three runners converge in the exit of continuous mixing arrangement 2.
As shown in Figure 2; Feeding pipeline 4 set inside have spiral propeller 5, and in the course of work, material will carry out drying earlier before getting into feeding pipeline 4; Fall into after material is dried on the spiral propeller 5 in the feeding pipeline 4 transmit, fusion, membrane; The plastic flat film smooth surface of producing, thickness is even, and quality is high.
As shown in Figure 3; Mixing arrangement 2 is provided with Material control device 6 continuously; For electrically connecting, Material control device 6 is provided with some displays 7, is used to show processing temperature, working time and the working speed of continuous mixing arrangement 2 between said Material control device 6 and the continuous mixing arrangement 2.
In the practical work process, the processing temperature difference of different coextruded layers is bigger, and is therefore just very important to the control of the processing temperature of material in the continuous mixing arrangement 2.If temperature is too high, makes easily bonding and then thickener take place between the material; If temperature is too low, then can cause discharging inhomogeneous, mobile performance is relatively poor.
In addition, the thickness of coextruded plastic film is the key of continuous mixing arrangement 2 controls, excessive velocities, and the coextruded plastic film can be thick partially, warping phenomenon occurs, do not reach product requirements; Speed is slow excessively, and the coextruded plastic film is thin partially, occurs aberration and dark line easily.
The symmetry that the extrusion molding feeding device of the utility model can the production good barrier property, mechanical strength is high, the transparency is good and the coextruded plastic film of unsymmetric structure, general centre is set to performance protective layer, the two-layer up and down extra play that is set to.
Reasonable in design, the compact conformation, easy to operate of the extrusion molding feeding device of the utility model; Are furnished with three feeding devices 1 on this device; And corresponding melt flow channel is arranged respectively, and the three-layer co-extruded plastic film thickness quality of producing like this is even, and the binding ability between each layer is strong.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
