Described roll wheel assembly includes main shaft, reel and roller, and described main shaft is connected with described driver power, and described reel is round structure, and one end of described main shaft is connected with the circle centre position of described reel;
Described roller is at least provided with six, and whole described rollers is arranged in the outer rim of described reel at equal intervals, and described roller can offset with described flexible pipe.
Preferably, described roller is divided into main pressing roller and half pressing roller, and described main pressing roller and described half pressing roller intert and arrange.
Preferably, described roller and described reel are rotatably connected.
Preferably, the utility model also includes briquetting, and described briquetting to be arranged on described pump head and to be oppositely arranged with described roller, has the installing space for accommodating described flexible pipe between described briquetting and described roller.
Preferably, the side that described briquetting is relative with described roller has arc groove, and the outer rim of described reel can stretch in described arc groove.
(3) beneficial effect
Designed by said structure, in the utility model, roller is provided with six, can ensure to have at least one to be half squeezed state between roller and flexible pipe during work, such structural design can improve hose life while raising precision, reduction outlet pulses intensity.
In addition, in the utility model, reel adopts disc structure, arranges roller at equal intervals at its edge, can not produce vibration, improve stability of the present utility model when it runs.
The utility model structure is simple, reasonable in design, be easy to realize, and is suitable for promoting.
