Abstract
The utility model provides on-line hot melt adhesive coating equipment for a steel-plastic composite pipe, which consists of a cooling setting sleeve and an adhesive coating die head which are connected directly. The utility model solves the problem of molding and adhesive coating mode of the existing plastic pipe for lining plastics and provides a novel molding coating mode, which gives consideration to both out-of-roundness and stability of adhesive coating pressure and flow. The utility mode is suitable for the field of producing the adhesive lining pipes by utilizing various types of the plastic pipes for lining plastics, such as PVC, CPVC, HDPE, PERT and the like, in the lining plastic PVC, CPVC, HDPE, PERT steel-plastic composite pipe.
Description
Technical field
The utility model relates to plastic cement tube forming and online coating thermosol field, is specifically related to a kind of dedicated pipe material forming and coating unit that steel-plastics composite pipe band gluing internal lining pipe is produced that be applied to.
Background technology
Lining plastotype steel-plastics composite pipe has the two-fold advantage of plastics and steel concurrently because of it, when guaranteeing to carry the health of water quality, can also bear bigger discharge pressure, thereby solve the problem that independent employing steel pipe or plastic tube are faced.And compare the plastic-coated-type steel-plastics composite pipe, and lining plastotype steel-plastics composite pipe antiseptic power is stronger, and service life is also longer.In Japan, lining plastotype steel-plastics composite pipe has accounted for Tall Building in Japan and has supplied water with more than 70% of pipe.And in China, lining plastic-steel plastic composite also begins to become pressure pipeline industry development field rapidly.
But one of major reason of restriction lining plastotype steel-plastics composite pipe development is exactly the big problem of processing technology existence that traditional lining plastotype steel is moulded pipe at present.Being mainly reflected in all first moulding backsight of plastic tube that lining moulds usefulness moulds.And moulding lining also need apply thermosol at pipe outer surface when moulding the plastic tube of usefulness, could guarantee to serve as a contrast plastic tube and steel pipe inwall good combination after moulding like this, reaches to serve as a contrast and moulds compound effect.But at present, the lining of domestic employing is moulded the online production mode that generally all adopts gluing after the first moulding with the moulding of plastic tube and coating technique, and shaped device is fully separately also to be separated with certain distance mutually with glue spreading apparatus.Plastic tube after the moulding just becomes the difficulty that this technology is difficult to overcome in the out-of-roundness that enters before being coated with rubber moulding.Because drawn behind the tube forming, the influence of factor such as extrusion output surging, the out-of-roundness during the instant cooling of typing just is very little, but be drawn to when being coated with before the rubber moulding very big variation has been arranged, this has just produced the uneven thereupon problem of gluing.And traditional tubing vacuum sizing device is water tank, and the used water tank of domestic enterprise all is that 4m or even 6m are long, and tubing enters through long like this distance again and is coated with rubber moulding, and out-of-roundness can't satisfy the requirement of uniform gluing.In addition, traditional rubber moulding that is coated with generally all adopts single molten bath structure aspect pressure stability, though obtaining certain effect aspect flow and the pressure control, but still can have the situation of plastic emitting instability of flow.Therefore in sum, traditional lining mould with the moulding of plastic tube and gluing mode be difficult to all satisfy that the production out-of-roundness is low, gluing uniformly lining moulded the requirement of usefulness plastic tube.
Domestic this type of novel tube forming and the incorporate device of gluing of yet there are no.
The utility model content
The purpose of this utility model is to overcome existing lining and moulds with the problem on plastic tube moulding and the gluing mode, and a kind of out-of-roundness and stable novel forming coating method of gluing pressure flow taken into account is provided.Be applicable to the field that lining is moulded variety production band gluing internal lining pipes such as using plastic tube PVC, CPVC, HDPE, PERT in lining plastotype PVC, CPVC, HDPE, the PERT steel-plastics composite pipe.
To achieve these goals, the utility model adopts following technical scheme:
A kind of online coating hot-melt adhesive equipment that is used for steel-plastics composite pipe is made up of direct-connected cooling and shaping cover and gluing die head.
Described cooling and shaping overlaps embedded spiral non-contact type cooling water channel.
The cooling and shaping cover comprises the toroidal vacuum chamber of three independences and sealing, and the inner surface of each vacuum chamber contact tubing has the long finedraw that is used to produce vacuum suction.
Described gluing die head is connected the employing flange with the cooling and shaping cover and connects.
The junction of described gluing die head and cooling and shaping cover also is provided with insulating collar.
Described insulating collar is made by polytetrafluoroethylmaterial material.
The described rubber moulding that is coated with adopts two molten baths structure.
Compared with prior art, the utlity model has following beneficial effect:
The traditional method that typing and gluing were separated when 1, the utility model had changed the state used lining of liner plastotype steel-plastics composite pipe and moulds plastic tube and produce, thus it is big and be difficult to the situation that effective way is solved to have prevented that effectively tubing from entering before the gluing mould out-of-roundness after qualitative;
2, because size of pipe and tubing no-cooling-water in whole passage directly contacts, reduced tube surfaces, improved lining greatly and moulded the surface quality and the lining of plastic tube and mould effect because ponding causes thermosol to apply the problem that produces bubble;
3, the rubber moulding that is coated with that traditional glue coated is used all is to adopt single molten bath even do not have the molten bath structure, and to the thermosol of different MI and melt pressure, the uniformity of coating and the stability of pressure are difficult to be guaranteed.This patent has been strengthened the flow of thermosol plastic emitting and the stability of pressure by the design in two molten baths, and it is easier to process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structure of the present utility model as shown in Figure 1, this device comprises following part: cooling and shaping cover 1 and be coated with rubber moulding 2.Wherein cooling and shaping cover 1 is to adopt embedded spiral non-contacting cooling water channel, comprises cooling water inlet 3, coolant outlet 4 and spiral water route 5.And adopt the also toroidal vacuum chamber 6 of sealing of three independences, and have long finedraw 7 at the typing cover inner surface of contact tubing, be used to produce the vacuum suction effect.Be coated with rubber moulding 2 and adopted flange 8 to be connected, and on the contact-making surface of flange and typing cover, be placed with polytetrafluoroethylene (PTFE) insulating collar 9 with the cooperation of typing cover.Be coated with rubber moulding 2 and adopted two molten baths structure 10, guarantee the pressure of gluing and stablizing of flow.
Add man-hour, fused materials is through extrusion die, enter into cooling and shaping cover 1, through having the cooling water channel in cooling water inlet 3, coolant outlet 4 and spiral water route 5 and having three independences and the toroidal vacuum chamber 6 of sealing, and having the Vacuum shaping structure of long finedraw 7 at the typing cover inner surface of contact tubing, tubing obtains cooling and shaping.Tubing behind the cooling and shaping by the transition structure that is combined with flange 8 and insulating collar 9 after, enter and be coated with in the rubber moulding 2.Be coated with rubber moulding and utilize two molten baths structure 10, tube surfaces is carried out uniform gluing, finally reach the purpose of typing and gluing.
