[0031] This embodiment also provides a feeding and replenishing method. Through the feeding and replenishing device provided by the above embodiment, the specific process is as follows: The driving motor is used to drive the lifting adjustment mechanism, the flip adjustment component and the automatic tensioning component to work together to achieve material replenishment. The operator first manually rolls the strip into the strip winding mandrel, and the automatic tensioning component buckles the strip mandrel to prevent it from falling off. Then the feeding and replenishing device is moved to the vicinity of the tape laying head, and the lifting adjustment mechanism button is manually pressed. The lifting adjustment motor drives the lifting adjustment screw to operate, thereby driving the lifting slide group to lift, and the strip will be automatically lifted to the preset height (fixed material replacement height).

[0032] Then the operator operates the flip adjustment component to adjust its posture, which rotates the horizontal flip seat and the vertical flip seat together to make the tape roll in a horizontal posture, so that the tape roll can be easily forked and moved horizontally for material replenishment.

[0033] The tensioning drive assembly starts working, and the driving motor drives the sleeve assembly screw mechanism to rotate, thereby driving the screw nut, small chuck and large chuck to move horizontally and adjust, and the roller mechanism is adjusted horizontally relative to the outer sleeve, thereby sending the strip roll into the unwinding mechanism of the tape laying head. When it reaches the predetermined position, the limit device reminds the operator, and the claw mechanism is in full contact with the unwinding mechanism. At the same time, the tensioning mechanism is automatically loosened, the strip roll is unloaded, and the loading of the strip is completed.

[0034] The feeding and replenishing device of the present invention is mainly used for assisting the lifting and loading and unloading of the tape roll. The flip adjustment mechanism and the automatic tensioning mechanism work together to adjust the tape roll to a horizontal posture, so as to achieve flexible fork lifting of the tape roll and horizontal movement. After the lifting and adjusting mechanism lifts the tape to a corresponding height, the flip adjustment mechanism rotates and aligns with the core shaft position of the tape laying head to load the material. The feeding and replenishing device operates smoothly and is easy to operate during the lifting and adjusting, fork lifting of the tape roll, and horizontal movement. It can better solve the problem of difficulty in lifting and loading and unloading the auxiliary tape roll during the laying process of the existing tape laying machine.
