The workflow of the coating machine: coating a roll of substrate, such as paper, cloth, leather, aluminum foil, plastic film, etc., with a special function of glue, paint or ink, and drying and winding.
The working principle of the coater: The working principle of the automatic coater for screen printing is the same, but its function varies according to different models and different manufacturers. The screen coater is provided with a device capable of clamping the frame on the vertical frame. The front and rear of the screen area is a horizontal coating mechanism consisting of a coating tank and mechanical or pneumatic components that control the angle and pressure of the coating tank.
Both ends of the coating mechanism are mounted on the vertical support arm of the coater, and the coating mechanism is moved up and down by the belt, chain or cable transmission, and coated along the surface of the screen. The commemorative head is connected to a servo or variable frequency motor for smooth operation and precise control of the position of the coating mechanism.
Before coating, the clean, stretched screen is loaded from the front of the coater, and some models can also be loaded into the screen from the side. Among the models designed for large format frames, side loading is more common. Because the frame is large and bulky, the side loading can make the lifting amount and the moving amount smaller. When the automatic screen coater is operated online with other automatic screen processing equipment (such as cleaning equipment, recycling equipment, drying equipment and developing machine), it is more convenient to mount from the side.
Regardless of how the screen is installed, once the screen is in the correct position, the pneumatic clamp or mechanical clamp is closed and the screen is locked. In order to make manipulation more convenient, many models have pedals to control the folder movement, and the operator can free up his hands to control the screen. After the screen is installed and the corresponding emulsion is poured into the automatic coater, the coating can be started. Depending on the function of the control system and equipment, the equipment can simultaneously coat both sides of the screen.
There are two kinds of coating methods, one is to apply the emulsion on the screen by a plurality of wet pressure manipulations; or the drying process is added after each coating. A machine for metering a liquid (or melt) polymer material such as a binder or a coating on a surface of a material. Simply put, the glue is applied to the film. Detailed details include gluing, drying, winding and tension control. The film may be PVC, PE, PET, etc., or may be some paper, such as a hot melt adhesive coated on the release paper.
The coating machine is designed and manufactured to meet the packaging requirements of cargo storage, transportation and mechanized loading and unloading. The tray coating machine, the top-type drag-type coating machine and the pre-drawing automatic film coating machine are designed and manufactured. Widely used with the export of foreign trade, food and beverage, irrigation, paper, dyes, plastics, electromechanical castings and other products, improve production efficiency, but also prevent damage during the handling of the goods, and play dust, moisture and Cleaning effect.
The working principle of the coating machine is to place the surrounding entangled object in the center of the turntable, start the turntable motor to roll, and naturally move the turntable to roll, so that the object realizes the surrounding surrounding entanglement film machine. At the same time, the elevator motor is also activated, which drives the entire assembly of the entanglement strapping machine to move up and down to achieve the circumferential entanglement of the object height direction, which realizes the surrounding entanglement package of the entire outer surface of the object. This not only facilitates the packaging requirements of goods storage, transportation and mechanized loading and unloading homework, but also reduces the production cost and improves the production efficiency. In the process of encircling entanglement, the main adjustment is the tension of the film and the film penetration. Generally, the film tension can be achieved by adjusting the rotational speed of the turntable and adjusting the rotational speed of the motor. As long as you know the faster the turntable speed, the slower the motor rolls, the tighter the film will be. Conversely, the looser the principle is not difficult to manipulate.
Application of coating machine: It is used in the coating of shoe materials, electronics industry, sponge, EVA, PE, cloth, etc.
External Cylindrical Grinding, cylindrical grinding is mainly carried out on an external cylindrical grinding machine, which is used to grind the outer cylinder, outer cone and shoulder end surface of shaft-type workpieces. During grinding, the workpiece rotates at a low speed. If the workpiece reciprocates in the longitudinal direction at the same time and the single-stroke or double-stroke movement in the longitudinal direction moves the grinding wheel relative to the workpiece, it is called longitudinal grinding.

If the width of the grinding wheel is greater than the length of the surface to be ground, the workpiece does not move longitudinally during the grinding process, but the grinding wheel continuously feeds the workpiece continuously, called the plunge grinding method. The efficiency of the plunge-cut grinding method is generally higher than that of the longitudinal grinding method. If the grinding wheel is trimmed into a forming surface, the plunge grinding method can be used to process the formed outer surface.
