Talking about the workflow of coater

workflow of coater: roll the substrate, such as: 4 If the operating mechanism is found to be ineffective, paper, cloth, leather, aluminum foil, plastic film, etc. shall be coated with a layer of glue, paint or ink with specific functions, and then rolled up after drying

coater working principle of automatic coater: the working principle of automatic coater used for printing plates with small moisture absorption is the same, but its performance varies according to different models and manufacturers. The vertical frame of the wire coater is equipped with a device that can clamp the frame. The front and back of the silk area are horizontal coating mechanisms, which are composed of coating grooves and mechanical or pneumatic parts that control the angle and pressure of the coating grooves

both ends of the coating mechanism are installed on the vertical support arm of the coater, and the coating mechanism moves up and down through the transmission of belt, chain or cable to coat along the surface of the wire. The transmission mechanism is connected to the servo or frequency conversion motor to make its operation stable and accurately control the position of the coating mechanism

before coating, load the clean and stretched version from the front of the coater, and some models can also load the version from the side. Among the models designed for large frame, the side mounted version is more common, because the frame is large and bulky, and the side mounted version can reduce the lifting and moving amount. When the automatic wire coater is online with other automatic wire processing equipment (such as Anhui Lishi Power Technology Co., Ltd. participating in the preparation and revision of national standards, cleaning equipment, regeneration equipment, drying device and developer), it is more convenient to install the plate from the side

no matter how the version is installed, once the version is in the correct position, the pneumatic clamping device or mechanical clamping device will close and lock the version. In order to make the operation more convenient, many models have foot pedals to control the version clamping action, and the operators can free up their hands to control the version. After installing the plate, fill the automatic coater with the corresponding photosensitive emulsion, and then start coating. According to the functions of the control system and equipment, the equipment can coat both sides of the silk at the same time

there are two coating methods: one is to apply photosensitive emulsion on the silk through multiple wet pressing operations; Or add reifenhuser's drying process with rethinking as the theme after each coating. A machine for quantitatively coating liquid (or melt) polymer materials such as adhesives or coatings on the surface of materials

it is applicable to the production of soft substrates such as pvc/pe film

simply speaking, glue is applied to the film. Specifically, it includes gluing, drying, winding and tension control

the film can be PVC, PE, pet It can also be some paper. For example, the re release paper is coated with hot melt adhesive

the coater is designed and manufactured in order to meet the packaging requirements of goods' centralized storage, transportation and mechanized loading and unloading operations. A series of products, such as tray coater, top pressing drag coater and pre drawing automatic film coater, are widely used in foreign trade export, food and beverage, irrigation, papermaking, dyes, plastic chemical industry, glass ceramics The containerization cost of electromechanical castings and other products can improve the production efficiency, prevent the damage of goods in the process of handling, and play the role of dust prevention, moisture prevention and cleaning

the working principle of the coating machine is to place the wrapped object in the center of the turntable, start the turntable motor to rotate, and naturally drive the turntable to rotate, so that the object realizes the peripheral film winding machine. At the same time, the elevator motor is also started to drive the whole assembly of the winding and binding machine to move up and down to achieve the winding of the height direction of the object, which realizes the winding and packaging of the entire appearance of the object. This is not only conducive to the packaging requirements of goods storage, transportation and mechanized loading and unloading operations, but also can prevent the damage of goods in the handling process, play the role of dust prevention, moisture prevention and cleaning, but also reduce the production cost and improve the production efficiency. In the winding process, the main thing is to adjust the tension of the film and wear the film. Generally, the film tension can be achieved by adjusting the rotating speed of the rotary table and the rotating speed of the motor. As long as you know that the faster the rotating speed of the rotary table is, the slower the motor rotates, the tighter the membrane will be. On the contrary, the looser the membrane is, this principle is not difficult to operate
