Description

Technical Field

[0001] The utility model relates to the technical field of water hose forming machines, in particular to a water hose forming machine. Background Art

[0002] A water hose forming machine is a highly specialized production equipment, mainly used for manufacturing various types of water hoses, including but not limited to fire hoses, agricultural irrigation hoses, and industrial water hoses, etc. This machine integrates advanced processing technologies and an automated control system, and can efficiently and precisely complete the entire production process of water hoses. The working principle of a water hose forming machine usually involves the supply, melting, extrusion molding, and cooling and shaping of plastic raw materials.

[0003] For example, a rubber extrusion integrated molding extruder with the publication number of CN107364105B, which relates to rubber molding equipment, aims to provide a rubber extrusion integrated molding extruder with the advantage of reducing the moisture contained in the rubber raw material during transportation in the extruder. The key points of its technical solution are: the barrel includes a plurality of fixed barrels and air extraction barrels arranged coaxially, the inner diameter of the air extraction barrel is smaller than that of the fixed barrel and is arranged at intervals with the fixed barrel, an air extraction hole is opened at the upper end of the air extraction barrel, an exhaust baffle block covering the air extraction hole is provided on the air extraction barrel, and a vacuum pumping device for extracting water vapor in the air extraction barrel is provided on the exhaust baffle block.

[0004] During the working process of the water hose forming machine, molten plastic raw materials are injected into the molding cavity. Since in the existing molding device, the raw materials are injected from a fixed position of the cavity, the raw materials cannot be evenly distributed inside the cavity. Uneven distribution of the raw materials will directly result in inconsistent thickness of the produced water hoses. Water hoses with uneven thickness may have problems such as insufficient strength and easy breakage during use, affecting the use effect and safety. For this reason, we propose a water hose forming machine. Content of the Utility Model

A soft pad is fixedly installed at the end of the movable rod 10 facing the material cylinder 2. Plastic raw materials are contained in the material cylinder 2. The raw materials are heated by the heating wires 5 to be melted. The molten raw materials are introduced into the transfer cavity 4 through the diversion pipe 3. Then, the raw materials are injected into different positions inside the inner cavity of the annular pipe 6 through a plurality of pipes 7, so that the raw materials are more evenly distributed in the inner cavity of the annular pipe 6, making the thickness of the produced water hose more uniform and improving the production quality of the water hose.
