Introduction to Brush Roller Polishing Machine
The polishing machine is composed of a body, a work roller, a swing feed roller, a brush roller, a vacuum system, and an electrical control part. There are three working rollers, namely polishing roller, leather grinding roller, and flannel roller, which are respectively equipped with felt roller, rubber roller, and steel roller as feeding rollers, making the machine capable of both more polishing and soft polishing. Among them, the leather grinding roller is equipped with a lateral oscillation mechanism, which rotates and grinds while also performing 55 times/minute reciprocating sliding along its roller axis to ensure fine grinding. There are two main types of polishing rollers: a bidirectional spiral groove roller made of artificial agate, which is divided in the middle of the roller. It is made of special fabric and pressed tightly by the two turbulent covers of the roller to form a spiral cloth roller. Alternatively, it can be wrapped with felt to form a felt roller without a spiral surface. It can also be wrapped with velvety soft paper or cloth to form a smooth paper (cloth) roller, 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 the high-speed rotation of the roller, which extends the leather while polishing the motorcycle. The leather debris and dust scraped by the friction are discharged from both ends of the roller along the spiral groove with the airflow. At the same time, the heat dissipation performance of the polishing roller is improved, the polishing resistance is reduced, and the continuous polishing time of the roller is extended. The feeding roller device is located 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 getting entangled with the working roller, and its rotation direction is the same as that of the polishing roller.
The vacuum system consists of a protective cover layer of the work roll and a vacuum duct inside the machine body to form a vacuum chamber. The induced draft fan discharges dust particles from the duct. At the outlet of the inner tube, the air volume is adjusted by a valve, and dust and debris are discharged into the dust filtering device. A safety baffle is set in front of the protective cover of the work roller. When a hand collides, the feeding roller returns to its non working position, and the main machine stops working. Normal operation can only be resumed after restarting.
The three-dimensional vibration strengthening polishing process is a combination of vibration cutting polishing and shot blasting strengthening processing. During the machining process, vibration is generated by an electric vibration exciter, causing 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. The polishing fluid and abrasive scratch the surface of the part, thus achieving enhanced polishing. The vibration polishing process is actually a mechanical rolling process, in which 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 and impact the surface of the workpiece, causing micro plastic deformation, thereby reducing surface roughness. The brightener acts on the surface of the workpiece, quickly removing oil and impurities, achieving a brightening effect, and improving the rolling quality. When working in a vibration system, brighteners have a strong cleaning effect, which can quickly remove some insoluble oil stains and impurities from the workpiece and abrasive surface.
The panel and motherboard are respectively controlled by a microcontroller, with automatic frequency finding and locking functions; By using a microcomputer to accurately generate five spark pulses and ninety-nine segments of patterns and enhanced pulses, the pattern state can realistically simulate electric spark patterns from matte to very coarse; The strengthened state can transfer and coat materials with high wear resistance such as tungsten carbide to the working surface of the workpiece, thereby greatly extending the workpiece
