Background

The glass fiber clew, i.e. the glass fiber clew, is formed by winding a tow composed of a plurality of single fibers with the diameter less than 24um which are drawn by molten glass. Because the glass fiber yarn balls are glass, mutual friction and collision are easy to generate in the packaging and transportation processes to cause fracture, and the product quality and use are influenced. Therefore, a film needs to be arranged outside the produced glass fiber yarn mass for protection.

In the glass fiber industry, when finished glass fibers are wrapped with a film and packaged, the glass fibers are input by two sections of conveyor belts which are butted in parallel; the initial positioning is carried out by means of the v-shaped guide pipe, and then the V-shaped guide pipe is sent to a working device; after the sensor detects that the yarn is in place, the turnover mechanism grabs the yarn roll by fingers and turns to a position parallel to the film feeding mechanism; at the moment, the fixing mechanism descends to press the yarn group; the film feeding mechanism feeds the film, and the disc where the yarn group is located rotates to complete film wrapping; the film feeding mechanism retreats, the film is cut off, the fixing mechanism ascends, the film pushing mechanism extends forwards, folding work is completed through reciprocating linear motion, then the turnover mechanism turns downwards, and finally a finished product is output by the conveying mechanism to complete film wrapping operation.

When the film covering machine works, a yarn group is driven by the turntable to reach the lower part of the film covering shaft rod; then, the motor is pneumatic, and the lead screw drives the film coating shaft rod to move downwards, so that a coating film on the film coating shaft rod is attached to the yarn roll; at the moment, a roller power wheel is started to drive a driving roller to rotate, a driven roller is connected with the driving roller through a soft belt to drive a yarn group to do rotary motion, and a coating film is driven by the yarn group to be wound on the surface of the yarn group through a film feeding mechanism; when the yarn roll rotates to a set position, the rotating wheel stops rotating, the film cutting resistance wire is heated instantly, the film cutting work is completed under the action of the air cylinder, and meanwhile, the motor is started in a reverse rotation mode to drive the film coating roll shaft to ascend; and then the power wheel is started again to drive the yarn group to rotate again, so that the coating film is attached to the yarn group more smoothly, and finally the power wheel is separated from the driving roller, and the coating process is finished. The gas in the wrapping film is extruded out in time in the winding process, and the yarn ball is not mixed with bubbles after wrapping; meanwhile, the tension of the coating film is more uniform, no crease is generated, and the flatness of the product is greatly improved; the control of the central processing unit realizes that the machine can intelligently calculate the coating amount of the coating film, realizes full-automatic coating, greatly reduces errors and is suitable for industrial production.
