Product Description

   Pneumatic high-tension screen stretching machine is an important equipment used in the screen printing industry, mainly used to make high-precision screen printing plates.

Working principle

It generates strong pulling force through pneumatic devices, acting on the four sides of the screen. The screen is stretched tightly on the screen frame to make the screen reach the required high tension state. Generally, the edge of the screen is fixed to the chuck part of the screen stretching machine. After starting the pneumatic system, the cylinder piston moves, driving the chuck to stretch the screen outward.

Main structure

• Frame part: provides stable support for the entire screen stretching process, usually made of solid metal materials, to ensure that there will be no shaking and other situations that affect the tension accuracy when stretching the screen.

• Pneumatic system: including cylinders, air pipes, valves and other components. The cylinder is a key component for generating tension. The compressed air drives the cylinder piston to move to achieve the stretching of the screen. The air pipe is used to transmit compressed air, and the valve can accurately control the flow and pressure of the gas, thereby adjusting the tension of the screen.

• Clamp part: used to clamp the edge of the screen to ensure that the screen will not slip during the screen drawing process. The clamping force of the clamp should be moderate, which should ensure that the screen does not loosen and cannot damage the screen.

• Tension measuring device: It can measure the tension of the screen in real time, which is convenient for the operator to accurately control the degree of screen drawing. Some screen drawing machines can also automatically adjust the screen drawing process according to the preset tension value.

Advantages

• High tension accuracy: It can accurately control the tension of the screen and produce a screen printing plate with uniform and stable tension, thereby ensuring the clarity and accuracy of the printed pattern. For example, when printing high-precision patterns such as circuit boards of electronic products, high-tension screen printing plates can transfer ink evenly and reduce pattern deformation.

• High work efficiency: The pneumatic drive method makes the screen drawing process fast and stable. Compared with the traditional manual screen drawing method, it greatly shortens the screen drawing time and improves the overall efficiency of plate production.

• Strong applicability: It can be applied to screens of different materials and sizes to meet various screen printing needs. Whether it is a fine silk mesh or a high-strength polyester mesh, the appropriate tension can be achieved by adjusting the pneumatic parameters.

Summary︰
The stretching machine is usually named after the dynamic form of the tension of the wire mesh on the surface of the screen frame. If the tension of the wire mesh is generated mechanically, it becomes a mechanical stretching machine. If the tension of the wire mesh is generated pneumatically, it becomes a pneumatic stretching machine. Machine, because the pneumatic stretching machine distributes the cylinders arranged in a matrix around the screen, so the tension generated is relatively large. The pneumatic stretching machine is relatively a high-precision screen printing screen production: such as: precision circuit board printing, four-color Dot printing. The larger the netting area of the pneumatic netting machine, the more cylinders are distributed around it, and the higher the price.
