Description
Technical field
The utility model relates to a kind of PP-R pipe production equipment, relates in particular to a kind of material extruder of producing for PP-R pipe.
Background technology
PPR tubing is compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance is easy, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable jacket, industrial fluids conveying, agricultural irrigation.
In recent years, along with continuing to increase of building industry, municipal works, hydraulic engineering, agricultural and the industry market demand such as industrial, Chinese PPR tubing industry had presented high speed development situation.Look into according to prediction network regulation, within 2009, plastic conduit output is 580.4 ten thousand tons, increases by Jan-Sept, 18.9%, 2,010 552.8 ten thousand tons of plastic conduit outputs on a year-on-year basis, increases by 28.23% on a year-on-year basis.Simultaneously, along with consumer improves constantly the quality requirements of product environmental protection, health, the aspect such as durable, China's plastic conduit is when output increases, product quality level improves constantly, the technological progress of industry is constantly accelerated, and brand scale enterprise is on the increase, and new material, new construction kind continue to bring out, advanced system design philosophies emerges in an endless stream, and functional more obvious, the application of product are further widened.Think, Chinese plastics pipe industry occupation rate of market has exceeded 30% in all ducted ratios at present.
Comprised material extruder at PP-R pipe production equipment, most of material extruder does not possess the function of double-layer co-extrusion, individual other double-layer co-extrusion material extruder complicated structure, and production cost is higher, and maintenance cost is also higher.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of material extruder of producing for PP-R pipe.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The material extruder of producing for PP-R pipe, comprise motor, machine barrel and extruder head, also comprise the first feed hopper, the second feed hopper, heater, external screw rod and inner screw, described inner screw is nested in described external screw rod, described inner screw length is greater than described external screw rod, described the first feed hopper and described the second feed hopper are all arranged on described machine barrel, the charging hole of described the first feed hopper is arranged on the top, one end of described inner screw, the charging hole of described the second feed hopper is arranged on described external screw rod top, and the other end of described inner screw connects described extruder head.
Motor as power, external screw rod is static, and inner screw can be static, also can keep the reverse rotation campaign with respect to external screw rod; The external screw rod of rotation is equivalent to the machine barrel of inner screw, and in the time that inner screw keeps static, interior external screw rod rotates with respect to machine barrel; In the time that inner screw rotates, interior external screw rod rotatablely moves with respect to machine barrel simultaneously.
Particularly, the silk mouthful direction of described external screw rod and the silk mouthful direction of inner screw are symmetrical.
Further, multiple described heaters are evenly arranged on the surrounding of described machine barrel.
The beneficial effects of the utility model are:
The utility model provides the material extruder of producing for PP-R pipe, and external screw rod and inner screw are set in machine barrel, and annex is less, has solved material extruder complicated structure, and the higher and high problem of maintenance cost of production cost, has the value of promoting the use of.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model for the material extruder of PP-R pipe production.
In figure: 1-the first feed hopper, 2-charging hole, 3-the second feed hopper, 4-machine barrel, 5-heater, 6-external screw rod, 7-inner screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the material extruder that the utility model is produced for PP-R pipe, comprise motor, machine barrel 4, extruder head, the first feed hopper 1, the second feed hopper 3, heater 5, external screw rod 6 and inner screw 7, inner screw 7 is nested in external screw rod 6, inner screw 7 length are greater than external screw rod 6, the first feed hopper 1 and the second feed hopper 3 are all arranged on machine barrel 4, the charging hole 2 of the first feed hopper is arranged on the top, one end of inner screw 7, the charging hole of the second feed hopper 3 is arranged on external screw rod 6 tops, the other end of inner screw 7 connects extruder head, the silk mouthful direction of external screw rod 6 and the silk mouthful direction of inner screw 7 are symmetrical, multiple heaters 5 are evenly arranged on the surrounding of machine barrel 4.
Motor as power, external screw rod 6 is static, and inner screw 7 can be static, also can keep the reverse rotation campaign with respect to external screw rod 6; The external screw rod 6 of rotation is equivalent to the machine barrel of inner screw 7, and in the time that inner screw 7 keeps static, interior external screw rod rotates with respect to machine barrel 4; In the time that inner screw 7 rotates, interior external screw rod rotatablely moves with respect to machine barrel 4 simultaneously.
Embodiment is above described preferred embodiment of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
