A fuel dispenser hose rewinding mechanism

Abstract

This utility model discloses a fuel dispenser hose winding mechanism, including a support base, a rotating wheel, and a locking block. The support base has symmetrically fixed blocks, and a belt is fixedly connected to each fixed block, with the belt passing through a sliding block. In this utility model, the output of a first motor rotates a first rotating shaft, which in turn rotates a drive wheel, which in turn moves a flat belt, ultimately rotating a second rotating shaft and a driven wheel, causing a sliding cylinder and a winding cylinder to rotate, thus winding up the fuel dispenser hose. During cleaning, the output of the second motor rotates the rotating wheel, causing the sliding block to slide along the belt, ultimately moving a cleaning brush to achieve cleaning and improve production efficiency. During disassembly, pushing the locking block allows the sliding cylinder, no longer restrained by the locking block, to slide on the second and third rotating shafts, allowing the winding cylinder to be removed. Installation and maintenance are simple, saving labor and production costs.

Description

Technical Field

[0001] This utility model relates to the field of winding mechanism technology, and in particular to a refueling machine hose winding mechanism. Background Technology

[0002] Fuel dispenser hose rewinding mechanisms not only improve safety, efficiency, and user experience but also reduce operating costs, making them an essential component of modern gas station design. By neatly storing the hoses, they reduce tripping hazards and other safety risks caused by tangled hoses, especially in busy gas station environments. Proper rewinding reduces hose wear and stretching, preventing exposure to potentially damaging factors and extending hose lifespan. Operators no longer need to manually manage the hoses, saving time and making the refueling process smoother and more efficient. Some advanced rewinding systems even support automatic retraction, further accelerating the workflow. However, currently available fuel dispenser hose rewinding mechanisms have significant drawbacks: firstly, cleaning debris from the bottom is difficult, affecting production efficiency; secondly, removing the hose after rewinding is time-consuming and laborious. Therefore, designing a fuel dispenser hose rewinding mechanism is essential. Utility Model Content
