Technical Field

[0001] The utility model relates to a tension-adjustable shaking-type heating carbon fiber widening mechanism, in particular to the technical field of textile machinery. Background Art

[0002] When the large-tow carbon fiber enters the yarn spreading mechanism, the fibers of the large-tow carbon fiber cannot be well dispersed due to the installation method of the yarn spreading roller, so that the yarn sheet cannot be evenly spread. Utility Model Content

[0003] The utility model provides a shaking type heating carbon fiber widening mechanism with adjustable tension, which is used to overcome the defect in the prior art that the yarn sheets of large tow carbon fibers cannot be evenly spread after entering the yarn spreading mechanism.

[0006] Furthermore, the heating device is a plurality of infrared heating lamp tubes arranged in parallel.

[0007] Furthermore, the transverse movement device comprises a transverse movement yarn spreading roller, one end of the transverse movement yarn spreading roller is connected to a transverse movement eccentric mechanism, and the transverse movement eccentric mechanism is connected to an output end of the driving motor.

[0008] Furthermore, a transmission shaft is provided in the inner cavity at the bottom of the frame, and both ends of the transmission shaft are connected to the lifting screw through a right-angle reducer.

[0009] Furthermore, a hand wheel is provided on the bottom outer wall of the frame, and the hand wheel is connected to the transmission shaft. The transmission shaft drives the lifting screw to move up and down by rotating the hand wheel.

[0010] The beneficial effect achieved by the utility model is that when the large-tow carbon fiber enters the yarn spreading mechanism, the tension of the yarn is changed by adjusting the upper and lower positions of the yarn spreading roller, the heating device heats the yarn to melt the binder contained in the carbon fiber, and the transverse yarn spreading roller moves back and forth at high speed so that the fibers of the large-tow carbon fiber can be well dispersed, and then a certain pressure is applied by the upper and lower tension rollers to obtain a uniformly spread yarn sheet, thereby obtaining a thinner carbon fiber yarn sheet with a lighter grammage.
