AI Technical Summary
The existing open mill used for producing oil drilling hoses has problems such as a small double-roll speed ratio and insufficient shearing force, resulting in incomplete dispersion of fillers. It also lacks a precise cutting device, requiring manual cutting of the rubber compound, which then scatters after cutting, leading to low material collection efficiency.
A two-roll mill for producing oil drilling hoses was designed. It adopts a design where the cutting drive wheel and driven wheel have the same diameter and are coplanar. The diameter of the drive gear is larger than that of the driven gear to achieve speed-increasing transmission. The length of the threaded rod matches the circumference of the roller. The cutting plate fits and cuts the hose in close contact with the roller. Double-sided baffles limit the hose. The material collection device is driven by the material collection drive wheel and driven wheel having the same diameter and are coplanar. The toothed gear meshes with the rack of the material tray. The return spring provides elastic return force to achieve automatic material collection.
It improves the stability and accuracy of cutting, ensures the consistency of hose cutting length and cut quality, increases material collection efficiency, reduces material waste, and enhances the automation level and processing precision of the open mill.
