Embodiment 1

[0027] A continuous production process for carat tubes, specifically comprising the steps of:

[0028] (1) Mixing material: Take 100 kg polyethylene and 2 kg black masterbatch, pour into the mixing machine and blend for 15 minutes for mixing;

[0029] (2) Heated extrusion: Vacuum feeding is used to suck the material into the hopper of host 1, the process temperature of host 1 is set to 165°C, start host 1, gradually increase the speed by 5 revolutions per minute, and start heating and extrusion;

[0030] (3) Flat belt winding: when the main machine 1 is started and the material is extruded from the flat belt mold 4, the flat belt is directly drawn to the winding mold 8 and wound continuously for more than 5 turns, and then the required product pitch of the forming machine 3 is adjusted;

[0031] (4) Round pipe winding: Start the auxiliary machine 2, gradually increase the speed by 5 revolutions per minute, make the round pipe extrude from the round pipe mold 5, pull the round ...

Abstract

The invention discloses a Krah pipe continuous-production device. The Krah pipe continuous-production device comprises a main machine, an auxiliary device, a forming machine, a flat belt mold, a circular pipe mold, a cooling bench, a cooling water nozzle and a winding mold. The Krah pipe continuous-production technology comprises the following steps of material stirring, heating extrusion, flat belt winding, circular pipe winding, cooling molding, fixed length cutting, bearing, slot winding, cooling molding, and examination and warehousing. The Krah pipe continuous-production device realizes pipe molding by the Krah pipe continuous-production device according to a steel band winding principle, a polyethylene raw material is subjected to heating melt extrusion by the main machine to produce a flat band and a circular pipe (with a PP tube in the interior), the flat band and the circular pipe are continuously winded and molded on the winding mold, and the product is cooled by water or combination of water and air. The Krah pipe continuous-production technology is free of natural gas in production, reduces a cost, realizes continuous production, and has a high yield and a reliable product mass ratio.

Description

technical field [0001] The invention relates to a production equipment for carat tubes, in particular to a continuous production equipment and a production process for carat tubes. Background technique [0002] As some domestic plastic sewage composite pipes have many disadvantages, such as plastic and steel composite municipal pipes used for sewage or drainage projects, the service life is greatly reduced, especially in coastal cities, where the water is salty and highly corrosive , Some projects use plastic and steel composite municipal pipeline products to collapse within 3-5 years, because the steel and plastic composite can never be integrated, through temperature deviation, thermal expansion and cold contraction plastic is easy to delaminate from the metal, colliding The corrosion of acid, alkali and salt will lead to the decline of metal performance, resulting in the collapse of municipal pipeline products and other accidents. The development of carat pipes has grown...
