Embodiment Construction

[0014] In the manufacturing method of water hose of the present invention, the required raw material of water hose is the plastic raw material such as PP resin, PE resin or PE resin reclaimed material, and its manufacturing process is:

[0015] (1) Fully mix the selected raw materials, color masterbatch and ingredients and put them into a container. The container can be a device such as a hopper.

[0016] (2) Put the mixed raw materials in the container into the extrusion device, the extrusion device operates continuously, plasticizes and melts the mixed raw materials to form a melt, and the extrusion device continuously transfers the melt from the gap of the forming mold Extrusion to form a continuous cylindrical billet;

[0017] (3) The tractor pulls one end of the cylindrical billet, so that the cylindrical billet walks evenly into the cooling and sizing device, and the cooling water cools the wall of the cylindrical billet. The cooling time is the time for the cylindrical...

Abstract

The invention discloses a manufacturing method of a water hose and manufacturing equipment of the water hose. The invention comprises the following processes: firstly, selected materials, color master batches and batches are fully mixed and then put into a container; secondly, the mixed materials are arranged into an extrusion device, the plasticization and melting are performed to the mixed materials to form molten substance, and the molten substance is continuously extruded from the clearance of a shaping mould by the extrusion device, so as to form continuous cylindrical blanks; thirdly, one ends of the cylindrical blanks are hauled by a hauling machine to evenly get into a cooling sizing device, and then the cooling is performed to the walls of the cylindrical blanks through cooling water; fourthly, vacuum pumping is performed to a sizing sleeve in the cooling sizing device, and the cylindrical blanks are sized to form primary products; fifthly, the primary products are hauled into a cooling water tank, the water cooling is performed to the primary products to form finished products. The manufacturing equipment of the water hose realizes the vacuum shaping by being equipped with the devices of a sizing cooling tank and a vacuum pump, etc. The manufacturing method and the manufacturing equipment of the water hose have the advantages of good shaping effect, high cooling speed, low production cost, greatly enhanced product quality and high pressure resistance of the finished products, etc.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a water hose manufacturing method and water hose manufacturing equipment. Background technique [0002] For a long time, when irrigating crops in rural areas in most parts of my country, flood irrigation is still adopted, which is time-consuming and labor-intensive, and water resources are seriously wasted. In recent years, with the promotion of new technologies and the enhancement of people's awareness of water conservation, irrigation hoses have begun to be accepted by farmers. However, the traditional method of manufacturing water hoses adopts an air-cooling process and the molding process is slow, so the water hoses produced have poor compressive resistance and are extremely easy to burst when used, which affects the wide-scale promotion and promotion of this product to a certain extent. application. Therefore, be badly in need of a kind of production technology and the ma...
