Technical Field

The embodiment of the invention relates to a glass fiber cutting machine, in particular to a glass fiber cutting machine and a movable cutter device thereof.

Background

In the production process of the refractory gypsum board, a certain amount of glass fiber needs to be added into slurry to improve the fire stability of the board. In other high quality gypsum boards, some gypsum board enterprises also add a small amount of glass fiber to the board to increase the strength of the board. The glass fiber is added in the following way: the segmented fibers are added into the calcined gypsum (CaSO4 & 1/2H2O), and the calcined gypsum is uniformly stirred and then enters a mixer to be hydrated into slurry. Because the finished segment glass fiber is dispersed and changed into flocculent during conveying, the conveying amount is easy to be unstable. Therefore, the strand-shaped glass fiber is cut into sections by a glass fiber cutting machine and directly added into the plaster, so that the feeding amount of the section-shaped glass fiber can be accurately controlled. However, when the existing cutting machine cuts off the glass fiber, the glass fiber is frequently cut continuously and is wound on the equipment due to the fact that the cutter and the pressing wheel of the cutter are worn and lose efficacy after being used for a long time.

The pressure of the pressure spring 63 can be adjusted through the adjusting bolt 62, and the pressing force of the pressing roller shaft 5 on the glass fiber 2 is adjusted.

As shown in fig. 1, the cutting device includes a stationary blade unit 7 and a movable blade unit 8. The fixed cutter device 7 and the movable cutter device 8 are matched to act to shear the glass fiber 2. The fixed cutter device 7 is arranged at the downstream of the driven roll shaft 4 and is used for receiving the glass fiber 2 conveyed by the driven roll shaft 4. The fixed blade device 7 includes a base 70 provided on the frame 1 and a fixed blade 71 fixed to the base 70.

As shown in fig. 1 and 4, the movable blade unit 8 includes a cutting roller 80 and a plurality of movable blades 81 provided on the cutting roller 80 and extending in the axial direction of the cutting roller 80. The movable knife 81 and the cutting roller shaft 80 are inclined at a certain angle in the axial direction, so that the movable knife 81 and the fixed knife 71 can be matched to shear in the operation process of the cutting roller shaft 80 and can sequentially shear from one side to the other side of the glass fiber 2 in a point contact mode, and the increase of motor load caused by the fact that the movable knife 71 and the fixed knife 81 shear in a line contact mode can be avoided. The movable blade 81 in this embodiment includes a plurality of blades and is provided at intervals in the circumferential direction of the cutting roller shaft 80, thereby improving cutting efficiency.

As shown in fig. 5, each moving blade 81 of the present embodiment is provided with air holes 810 penetrating both sides to prevent the moving blade 81 from disturbing air during high-speed rotation to fly the glass fiber 2.
