Abstract

The utility model relates to a device having circular opening and used for forming or connecting of plastic pipe, in particular pertains to an equipment of using new a core-mold and vacuum cooling box to produce PPR pipes. The technical program of the utility model is the utility model comprises an extrusion machine and a machine head. The utility model is characterized in that the machine head2 is connected with the vacuum cooling box4 and water groove5 through a pipe3. Cooling water is injected in the water groove. Wherein, the core-mold of the machine head is curve structure and comprises a rear concave curved circle K, a concave curved circle K and a curved circle K. The utility model has the beneficial effects of: due to the vacuum cooling box spraying device of the length 60-80cm and water groove immersion cooling device of the length 3-4m the utility model improves the quality issues of the original products, the rate of the defects reduced by 30%, the space saved by 70% and the consumption of water and electricity saved by 30%.

Description

Adopt novel core, the poly-ice chest of vacuum to produce the equipment of PPR tubing

Technical field

The utility model includes annular opening, is used for the moulding or the jockey of tubing plastics, especially belongs to the equipment that adopts novel core, the poly-ice chest of vacuum to produce PPR tubing.

Background technology

In the prior art, its core of equipment of producing plastic pipe all is the circle that adopts orthoscopic, cooling device all adopts 6 meters long spray cooling devices, this device is used to produce antibiotic PPR tubing, can there are the following problems, 1, cooling device must have enough length, because length is long more, just help more eliminating joint line and improving the packing of goods internal structure, but not only consume energy but also take up space at shaping area; 2, do not have enough interior pressures and rate of extrusion too fast, melt can not fully be plastified evenly, causes the percent defective of goods to improve; 3, the tubing of a kind of specification of every production must change mould one time, and labour intensity is big, and consumption worker consuming time; 4, through regular meeting cause raw material to decompose because of the head back pressure is too high and also power consumption big, and product mechanical performance and surface smoothness can not reach problems such as optimized control.

Summary of the invention

The purpose of this utility model is to provide a kind of equipment that adopts novel core, the poly-ice chest of vacuum to produce PPR tubing, makes when producing antibiotic PPR tubing that power consumption is big, product mechanical performance and the unmanageable problem of surface smoothness improved greatly and solve.

Technical solution adopted in the utility model is: it comprises extruding machine, head, it is characterized in that: head 2 links to each other by the poly-ice chest 4 of tubing 3 and vacuum, tank 5, is marked with cooling water in the tank; Wherein, core in the head adopts the curvilinear style structure, and it is made up of recurve curvilinear style circle, sag vertical curve formula circle and curvilinear style circle, and it is made up of the also employing curvilinear style structure of mouthful mould correspondence recurve curvilinear style circle K, sag vertical curve formula circle K and curvilinear style circle K.

The beneficial effects of the utility model are: 1, because the utility model changes the core of traditional linear type structure into the core of curvilinear style structure, the Tibetan material amount that has increased, therefore shortened the length of core, by original effective length is to shorten to 21-30 centimetre about 60 centimetres, make melt shorten in the residing time of core section, increased the resistance of melt like this and promptly increased interior pressure in the exit, make the mutual winding power enhancing of strand in the material, improved the melt strength of melt, do not cause the destruction of molecular structure again and reduce the mechanical performance of goods because of undue the shearing, further plasticizing is even thereby make material, has improved the yield rate of goods; 2, reduce the more number of times of mold exchange, as: can produce the tubing of φ 32, φ 40, φ 50, φ 63 specifications with the mould of φ 63, enhance productivity, reduce labour intensity, the time and labour saving; 3, owing to adopt the poly-ice chest spray equipment of vacuum and the long tank of 3-4 rice of 60-80 centimetre length to soak cooling device, improved original Products Quality problem, defect rate has reduced by 30%, and the space has saved 70%, the water yield saving 30% of consumption; 4, owing to change the linear pattern core into the curvilinear style core, under equal conditions, as the motor that adopts 35KW on the extruding machine being changed into as long as adopt the small machine of 18.5KW to adapt, saved power consumption greatly, the electric weight of consumption can be saved more than 30%.
