What is the purpose of a tactile film coating machine?
What is the purpose of a tactile film coating machine? The tactile film coating machine is suitable for footwear, electronics industry, sponge, EVA, PE, fabrics, etc.
Tension system
1. Process requirements
The coating machine needs to evenly adhere adhesive or ink substances to the surface of aluminum foil, plastic film or fabric, which requires high coating process requirements. Not only does the coating need to be highly uniform, but it also needs to change the roll at high speed and without stopping to improve productivity.
2. Program advantages
The frequency converter has completed tension control at all levels, using tension sensors for tension control, and the system is simple and stable. PLC or synchronous controller can be used to control the speed of the drive roller frequency converter, while also serving as a line speed signal for other frequency converters.
S350 closed-loop tension control (inductive vector control) maintains constant tension during acceleration and deceleration, saving installation tension
The space of the drum can reduce machine costs, while ensuring a very uniform coating effect through high-precision control.
Dual position recycling rolls have necessary active functions, which can automatically replace rolls at high speed without stopping the machine and improve work efficiency. At the same time, correct scroll adjustment can avoid vegetable style defective scrolls, resulting in better scroll effects
What is the process of a tactile film coating machine?
Roll substrates (such as paper, cloth, leather, aluminum foil, plastic film, etc.) coated with specific functional adhesives, paint, or ink, dried and air dried.
The working principle of the automatic coating machine 3360 is the same as that of the automatic coating machine used for screen printing boards, but its performance varies depending on the model and manufacturer. The screen coating machine is equipped with a fixed mesh device on the vertical frame. The horizontal coating mechanism is located in front and behind the screen area, consisting of mechanical or pneumatic components that control the angle and pressure of the coating slot and coating slot.
The coating mechanism is installed at both ends on the vertical support of the coating machine, and is driven up and down by belts, chains, or cables to coat along the surface of the wire mesh. The transmission mechanism is connected to a servo or variable frequency motor, which works smoothly and can accurately control the position of the coating mechanism.
Before coating, install a clean and tight mesh plate in front of the coating machine, and some models can also be installed on the side of the mesh plate. In models designed for large grid frameworks, side plate making is more common. Because the mesh frame is large and heavy, side plate making can reduce lifting force and movement. The automatic screen coating machine is more convenient to install on the side panel when working online with other automatic screen processing equipment such as cleaning equipment, regeneration equipment, drying equipment, and developers
No matter how the mesh board is installed, once it is in the correct position, the pneumatic or mechanical clamping device will close and the mesh board will be locked. For easier operation, many models have pedal control clamp actions, allowing operators to free up their hands to control the mesh board. After installing the screen board and injecting the corresponding photosensitive emulsion on the automatic coating machine, the coating can begin. According to the functions of the control system and equipment, the equipment can paint both sides of the silk mesh simultaneously. There are two methods of coating. One method is to apply a photosensitive emulsion on the screen through multiple wet compresses. Alternatively, a drying process can be added after each coating. A machine that quantitatively applies liquid (or molten) polymer materials (such as adhesives or paints) on the surface of materials.
Suitable for producing PVC/PE film and other soft substrates
Simply put, it is to apply adhesive on the film. Specifically, it includes adhesive, drying, rolling, and tension control.
The film can be PVC, PE, PET. It could be, or it could be, a type of paper that is coated with hot melt adhesive on shaped paper.
