To improve the pass rate of mask production and the continuous operation stability of the equipment, the fully automated production line involves several core technologies, mainly including the KF94 Fish Mask Machine fabric unwinding control technology and the nose bridge wire feeding technology. So what is the key technology of the KF94 Mask Machine? Let's take a look at it next.

Unwinding control technology of fabric

The material feeding of the KF94 Mask Machine is conveyed by the traction mechanism, and the designed flat mask feeding rack is designed with 4 feeding shafts. Driven by the power source, the cloth roll is driven to rotate, so that the mask cloth is gradually released, and the roll material rotates around the roller shaft. However, during the conveying process, due to the inertia of the coil material, the coil material increases its rotation speed with the inertia, thereby accelerating the unwinding speed of the coil material, resulting in uncontrollable conveying speed and affecting the processing accuracy of the subsequent process. To solve the above problems, although a damping mechanism is provided on the roller shaft in the prior art, when the coil conveying is stopped, under the action of its inertia, although the damping mechanism reduces the rotation speed of the coil, the coil will still rotate, causing automatic feeding, making the fabric wrinkled, and affecting the production quality. The unwinding control mechanism can prevent the coil from being uncontrollable due to its inertia when the coil is conveyed. It can effectively offset the inertia of the coil, thereby improving the processing accuracy of the subsequent process. The working principle of the unwinding control mechanism is: when working, under the action of the hammer body's gravity, the pressing piece is deformed and pressed against the surface of the coil material. To speed up the unloading speed, since the pressing sheet is pressed against the surface of the coil material, the coil material needs to overcome the friction force of the pressing sheet to rotate. When stopping the conveying of the coil material, the frictional force also counteracts the force generated by the inertia of the coil material, so that the coil material stops moving, preventing the excess fabric from being conveyed forward, causing the fabric to wrinkle and affecting the production quality of the KF94 Mask Machine. Since the pressing sheet is always pressed against the surface of the roll material during the conveying of the cloth, the pressing sheet can scrape the surface of the cloth more smoothly, thereby effectively improving the production quality of the mask. Among them, the tablet is designed in an arc shape. generated force.


Nose bridge wire feeding technology

The feeding of the nose bridge line of the KF94 Mask Machine is one of the technical difficulties of the entire mask production line. How to ensure that the nose bridge line is cut and moved to the welding position of the mask fabric and does not move relative to the fabric, requires the innovative design of this part of the mechanism. To overcome the shortcomings of the prior art, a nose bridge wire conveying device is designed, which mainly includes a plurality of conveying group wheels, a wire feeding drive mechanism for driving the rotation of the plurality of conveying group wheels, an active feeding mechanism, a tangent group wheel, and a driving tangent group. The tangential drive mechanism of the wheel rotation.

Its working principle is as follows: the wire feeding drive mechanism drives the wire feeding wheels of multiple conveying group wheels to rotate, and drives the continuous nose bridge line between the wire feeding wheel and the supporting wheel to move forward; Under the action of the thread cutter on the cutting wheel, the continuous nose bridge line is cut off to form a separate nose bridge line; at this time, during the rotation of the cutting wheel, the rear of the separate nose bridge line continues to be conveyed, so that the separate nose bridge line is continuously conveyed. The nose bridge line continues forward a short distance from

The front part of the nose bridge wire of the separate KF94 Mask Making Machine is moved to the mask fabric of the support table to realize the docking with the mask fabric; There is an arc-shaped intermediate guide between the front and rear sides; then, driven by the active feeding mechanism, the feeding wheel rotates, thereby driving the separate nose bridge line and the mask cloth after being joined with the mask fabric to move forward synchronously Move to ensure that the separate nose bridge line can continue to move forward smoothly after being cut, to avoid the lack of power of the nose bridge line and the deviation from the mask fabric.
