Fire hose inner and outer tube casing machine

Abstract

The invention discloses a fire hose inner and outer layer pipe sheathing adhesion machine. The fire hose inner and outer layer pipe sheathing adhesion machine comprises a feedbox, a guiding device, an expanding hook, a belt-type driving mechanism, a workbench, a limit switch and a glue pool, wherein a pulley and the limit switch are respectively arranged at the two ends of the workbench; two column piles are arranged on a workbench top at an outer layer pipe leading-in end; the belt-type driving mechanism is arranged on one side surface of the workbench; a conveying belt in the belt-type driving mechanism is provided with a shifting fork, and the stroke of the shifting fork is controlled by the limit switch; and firstly the shifting fork moving to and from along with conveying is used for driving the guiding device put on the workbench to move to the left, the guiding device for pulling a glue pipe is located by the column piles, and the shifting fork returns and drives the expanding hook arranged on the workbench and having hooked an outer layer pipe to move to the right, thereby achieving the purpose of mutual sheathing adhesion. The fire hose inner and outer layer pipe sheathing adhesion machine accurately sheathes and adheres the outer layer pipe and the glue pipe by fully using the structural function of reciprocating motion of the conveying belt of the belt-type driving mechanism in conjunction with the constant speed pulling of the conveying belt and is high in production efficiency. Most importantly, the fire hose inner and outer layer pipe sheathing adhesion machine greatly reduces the labor intensity of operators.

Description

technical field [0001] The invention relates to a fire hose production equipment, in particular, the invention relates to a fire hose inner and outer layer pipe fitting machine. Background technique [0002] Today, the fire hoses deployed in buildings and public places are all lined with a layer of rubber hose to meet the needs of transporting high-pressure water. The basic structure of commercially available fire hoses is the same, and they are all made of three-layer tubes. The outer tube is a fiber knitted product, the inner liner is a rubber tube, and the outer tube and the inner liner are a bonding layer. The fire hose is a typical slender flexible hose with a common diameter of about 50-180mm and a deployed length of 25-35m. One of the key processes in the manufacture of fire hoses is to line the rubber hose into the outer tube, and evenly coat a layer of adhesive on the joint surface of the two. The industry generally uses manual lamination and manual pulling to achi...
