Introduction to Brush Roller Polishing Machine

The polishing machine consists of a machine body, a work roller, a swing feed roller, a brush roller, a dust suction system, and an electrical control part. There are three working rollers, namely polishing roller, buffing roller, and flannelette roller. They are respectively equipped with felt roller, rubber roller, and steel roller as feeding rollers, making the machine both more polishing and soft polishing. The buffing roller is equipped with a lateral vibration mechanism, which performs 55 times/minute reciprocating sliding along the axial direction of the roller during rotary grinding to ensure fine and dense grinding. There are two main types of polishing rollers: a two-way spiral groove roller made of artificial agate that splits from the middle of the roller, which is made of special cloth in a circular shape, and pressed tightly by two turbulent covers of the roller to form a spiral cloth roller. Alternatively, a felt roller without a spiral surface can be wrapped with a felt roll, or a smooth paper (cloth) roller can be wrapped with a velvety soft surface or cloth roll, which can be used for polishing different leather products and different processes.
The guide angle and groove size of the spiral groove on the polishing roller are specially designed to facilitate motorcycle polishing while the leather is stretched during high-speed rotation of the roller. The leather scraps and dust scraped by polishing are discharged along the spiral groove along the air flow from both ends of the roller, while improving the heat dissipation performance of the polishing roller, reducing polishing resistance, and extending the continuous polishing time of the roller. The feeding roller is installed on a swing frame and is controlled by a foot pedal to approach the polishing roller. Therefore, adjusting the swing frame can adjust the gap between the feeding roller and the working roller. The brush roller below the polishing roller is used to prevent leather from wrapping the working roller, and its rotation direction is the same as that of the polishing roller.
The dust suction system consists of a protective cover interlayer of the work roller and a dust suction air duct inside the machine body to form a dust suction chamber. The induced draft fan discharges dust particles from the duct through the air duct. The air volume at the outlet of the inner tube is adjusted by a valve, and dust is discharged into the dust filter. A safety baffle is provided in front of the protective cover of the work roller. When a hand collides, the feed roller returns to the non working position, and the host machine stops working. Normal operation can only be resumed after restarting.
Three-dimensional vibration enhanced polishing process is a combination of vibration cutting polishing and shot blasting strengthening processing. During the processing process, vibration is generated by an electric vibration exciter, which generates a certain amplitude and frequency of vibration between the grinding medium and the processed part, causing irregular collisions between the strengthening medium and the three-dimensional direction of the workpiece, and the polishing fluid and abrasive rub against the surface of the part, thereby achieving enhanced polishing. The vibration polishing process is actually a mechanical polishing process. In this process, the workpiece, abrasive, and brightener form a system. The abrasive uses the vibration of the high-frequency bottom radiation of the vibration groove to obtain energy to impact the workpiece surface, causing it to produce microscopic plastic deformation, thereby reducing surface roughness. The brightener acts on the workpiece surface, rapidly removing oil and impurities from the workpiece surface, achieving a brightening effect, and improving the polishing quality. When working in a vibration system, brighteners have a strong cleaning effect, enabling some insoluble oil and impurities to quickly separate from the workpiece and abrasive surface.
The panel and motherboard are controlled by a single chip microcomputer, with automatic frequency finding and locking functions; A microcomputer accurately generates five gear spark pulses, ninety-nine segments of patterns, and enhanced pulses. In the pattern state, it can realistically simulate electrical spark patterns ranging from matt to very coarse; The strengthened state can transfer and coat materials with high wear resistance such as tungsten carbide onto the working surface of the workpiece, thereby greatly extending the service life of the workpiece; Due to the improvement of the acoustic wave output circuit, the machine is very suitable for vibration grinding of rough surfaces using fiber oilstones and diamond files; The addition of a voice prompt function with artificial intelligence for real person vocalization provides a strong guarantee for the correct and safe use of the machine.
