Abstract
The utility model discloses a plastic pipe sizing device which comprises an entrance end and sizing components connected on the entrance end and surrounding and supporting a plastic pipe. Compared with the prior art, the plastic pipe sizing device has the advantages that the structure is simple, valid seal of a vacuum shell body relative to the outside is guaranteed at the entrance end, heading phenomena of a working extrusion plastic pipe are avoided, and absolute circles are achievable every time the diameter is adjusted.
Description
Technical field
The utility model relates to a kind of diameter-setting equipment, refers to especially a kind of diameter-setting equipment of plastic tube.
Background technology
In the process of producing plastic tube, because plastics may produce contraction according to various factors, and it to be controlled in the scope of requirement, generally all need to use diameter-setting equipment.Existing diameter-setting equipment is to adjust according to the plastic tube of various outer diameter mostly, but the problem that for this reason needs to consider is that the order of a lot of producers is always very little in batches, that is to say, needs constantly to adjust extrusion equipment.This adjustment can cause extrusion equipment to shut down, and is changing the single parts of extruding, and this can cause very high energy consumption and plastic material consumption.
The utility model content
The utility model proposes a kind of diameter-setting equipment of plastic tube, solved the shortcoming that high energy consumption in the prior art and plastic material consume.
The technical solution of the utility model is achieved in that
A kind of diameter-setting equipment of plastic tube is characterized in that, described diameter-setting equipment comprises arrival end, and is connected on the arrival end, surrounds the also sizing member of supporting plastic pipe.
Described arrival end is provided with in the sagittal plane, but is distributed in the overlapping parts of the radiai adjustment around the plastic tube for the treatment of sizing.
Described sizing member comprises two layer band spares, and these two layer band spares mutually intersect with the crossing net case form and are hinged at the intersection point place.
Described layer is held level with both hands on the neat overlapping parts that are hingedly fixed in arrival end with one of part.
Be provided with slit between described overlapping parts, be provided with the cooling pressure water out in this slit.
Compared with prior art, the utility model has the advantage of, structure is relatively simple, and has guaranteed vaccum case phase effective sealing to external world at arrival end, avoided the thick phenomenon of pier of the extrusion plastic pipe in the operation, and when each change diameter, absolute circle has been arranged.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the extrusion equipment of plastic tube;
Fig. 2 is the structural representation of the diameter-setting equipment of a kind of plastic tube of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of diameter-setting equipment of plastic tube only is parts in the extrusion equipment of plastic tube, and a whole set of extrusion equipment comprises extrudes unit 1, and it comprises hopper 2, extrusion screw rod 3 and extrusion die 4.The used granular or powdery thermoplastic 5 in unit is extruded in hopper 2 supplies.In extrusion device 1, pellet or powder are heated, mix and plastify.Subsequently, plastics are extruded screw rod 3 as plastic material and push extrusion die 4, just receive the extruding in slit, ring section herein.
From extrusion die 4 out after, also the plastic tube 6 of deformable heat is pulled through sizing cooling unit 8 by being arranged on the drawing unit 7 of extruding line one end, wherein sizing cooling unit 8 comprises a vaccum case 9, and this housing is provided with the diameter-setting equipment 10 of tubulose at its entrance.The diameter of diameter-setting equipment 10 can electrodeless adjusting, and like this, the plastic tube 6 of above-mentioned also not moulding of extruding can be desired any number by sizing just.Plastic tube 6 enters cooling section 11 after by sizing cooling unit 8, here, plastic tube is cooled to room temperature.
As shown in Figure 2, a kind of diameter-setting equipment of plastic tube, described diameter-setting equipment 10 comprises arrival end 12, and is connected on the arrival end 12, surrounds the also sizing member 13 of supporting plastic pipe.Arrival end 12 is provided with in the sagittal plane, but is distributed in the overlapping parts 14 of the radiai adjustment around the plastic tube for the treatment of sizing.Sizing member 13 comprises two layer band spares 15,16, and these two layer band spares 15,16 mutually intersect and are hinged at the intersection point place with the crossing net case form.Layer is with part 15,16 one hold level with both hands on the neat overlapping parts 14 that are hingedly fixed in arrival end.14 of overlapping parts are provided with slit, are provided with the cooling pressure water out in this slit.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
