Description
Technical field
The present invention relates to a kind of rear co-extrusion regulating positioning device.
Background technology
After co-extrusion refers to that a kind of material (such as PVC) is completely shaping, then with the expressing technique of another kind of material (such as SPVC) composite molding, remarkable advantage to save manpower, reduces production cost, enhance productivity.The conventional mode of current SPVC and PVC co-extrusion to wear after glue strip type soft or hard co-extrusion after co-extrusion and viscose top formula soft or hard.In order to make the shaping of adhesive tape meet design requirement, except ensureing the shape of adhesive tape and meeting the requirements, also must ensure the position between adhesive tape and base material, for this reason, rear co-extruding mould just must design the positioner of base material.The principle that in prior art, most of mould generally adopts face to contact positions base material, base material just inevitably produces with mould surface and rubs, the surface roughness of mould surface, whether there is impurity etc. will have influence on the surface quality of base material, if the position between base material and mould is unreasonable, the adhesive strength between adhesive tape and base material also can be reduced.
Summary of the invention
The principle that the most of moulds that the object of the invention is to solve generally adopt face to contact positions base material, base material just inevitably produces with mould surface and rubs, the surface roughness of mould surface, whether there is impurity etc. will have influence on the surface quality of base material, if the position between base material and mould is unreasonable, the problem of the adhesive strength between adhesive tape and base material also can be reduced.
The technical solution used in the present invention is: rear co-extrusion regulating positioning device: comprise adjustment screw, fixed block, slide block, the first hold-down screw, the second hold-down screw, fixed axis, bearing, described fixed block is provided with screwed hole, one end of described adjustment screw is fixedly connected with slide block through the screwed hole on fixed block, first hold-down screw is fixed on fixed block, one end of second hold-down screw is connected through slide block and fixed axis, and described bearing is movably connected on fixed axis.
As further improvement, described first hold-down screw has 2, and described second hold-down screw has 2, and one end of two the second hold-down screws is all connected through with fixed axis, and described bearing has 2, lays respectively at fixed axis both sides.
As further improvement, described fixed axis is provided with two pads, and 2 pads lay respectively at the outside of a bearing.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to process, workable, be applicable to co-extrusion after multiple section bar glue strip type soft or hard, utilize the position of adjustment screw regulating positioning device, the adhesive tape face of base material and mould is made to be in a rational position, strengthen the adhesive strength between adhesive tape and base material, and location is reliable, stability of the production process is good, decrease the relative motion between section bar visible face and mould to greatest extent, eliminate the scuffing produced because of the friction between base material and mould.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention.
Fig. 2 is partial enlarged drawing of the present invention.
Shown in figure: 1 adjustment screw, 2 fixed blocks, 3 first hold-down screws, 4 second hold-down screws, 5 fixed axis, 6 bearings, 7 pads, 8 pads, co-extrusion plate after 9,10 die holders, 11 sprues, 12 co-extrusion material pan feeding pipelines.
Detailed description of the invention
The present invention is described further below.
As shown in the figure, the embodiment that in the present invention, regulating positioning device adopts: comprise adjustment screw 1, fixed block 2, slide block 3, first hold-down screw 4, second hold-down screw 5, fixed axis 6, bearing 7, described fixed block 2 is provided with screwed hole, one end of described adjustment screw 1 is fixedly connected with slide block 3 through the screwed hole on fixed block, first hold-down screw 4 is fixed on fixed block 2, one end of second hold-down screw 5 is connected through slide block and fixed axis 6, described bearing 7 is movably connected on fixed axis 6, described first hold-down screw 4 has 2, described second hold-down screw 5 has 2, one end of two the second hold-down screws is all connected through with fixed axis, described bearing 7 has 2, lay respectively at fixed axis 6 both sides, described fixed axis 6 is provided with two pads 8, 2 pads lay respectively at the outside of 2 bearings.
Mould used for the present invention comprises rear co-extrusion plate 9 and die holder 10, is provided with sprue 11 and co-extrusion material pan feeding pipeline 12 in described rear co-extrusion plate, and sprue can pass through for base material.During use, fixed block 2 is connected on rear co-extrusion plate 9 by the first hold-down screw 4, because one end of described adjustment screw 1 is fixedly connected with slide block 3 through the screwed hole on fixed block, therefore turning adjusting screw can drive the slide block 3 be connected with it to move, thus make to be connected to by the second hold-down screw 5 bearing 7 on the fixed axis 6 on slide block near or away from the base material treating co-extrusion, the moulding section of the adhesive tape face of base material and mould co-extrusion material pan feeding pipeline is made to be in a rational position, and base material to be matched the guiding realized when base material moves by the moulding section of the adhesive tape groove of base material material extrusion pan feeding pipeline together, and base material can pass through sprue smoothly, the location to base material is realized by the guiding of moulding section and the compression of bearing 7, make base material away from bearing 7 by the compression of bearing 7 and towards mould surface side tilt do not contact with mould surface, strengthen the adhesive strength between adhesive tape and base material, decrease the relative motion between section bar visible face and mould to greatest extent and eliminate the scuffing produced because of the friction between base material and mould.Structure of the present invention is simple, easy to process, workable, is applicable to co-extrusion after multiple section bar glue strip type soft or hard.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention carries out all are dropped in protection scope of the present invention.
