Then, according to the width of the insulating paper 4, the rotating adjusting rod 82 drives the two guide blocks 81 to move and adjust the distance between the two guide grooves 811 until the two side edges of the insulating paper 4 are positioned in the guide grooves 811, so that the insulating paper 4 stably passes through the guide grooves 811; when the insulating paper 4 enters the flanging block 90, the insulating paper 4 can be gradually folded upwards due to the gradual reduction of the distance between the two inclined planes 900, and the distance between the two inclined planes 900 can be adjusted by changing the relative position of the flanging block 90 locked on the guide block 81, so that the width of the flanging edge of the insulating paper 4 is adjusted; when the folded edge of the insulating paper 4 passes through the folding block 91, the folded edge of the insulating paper 4 can be continuously folded inwards due to the gradual shallow depth of the folding groove 910. Then, the pressure of the upper and lower pressure rollers 210 and 211 against the insulating paper 4 is adjusted by changing the compression amount of the spring 222 by rotating the adjustment screw 223; the rotary cutting rotating shaft 61 can drive the lower end of the swing rod 65 to swing back and forth along the discharging direction of the insulation paper 4, and can drive the upper pressing roller 210 and the lower pressing roller 211 to rotate intermittently under the action of the one-way bearing 66, so that the adhesive tape 5 can be further tightly adhered to the insulation paper 4, and the insulation paper 4 can be driven to discharge. Finally, according to the required cutting length of the insulating paper 4, the distance between the upper end of the position adjusting swing rod 65 of the moving rod 64 and the cutting rotating shaft 61 is changed through rotating the adjusting screw rod 63, the intermittent swing angle of the lower end of the swing rod 65 is adjusted when the cutting rotating shaft 61 rotates for a circle, the intermittent rotation angle of the lower pressing roller 211 driven by the one-way bearing 66 can be adjusted, the length of the insulating paper 4 conveyed to the pressing roller 21 when the cutting rotating shaft 61 rotates for a circle is adjusted, and the insulating paper 4 which is required in length and is folded by pasting is finally cut out as the cutter 70 rotates for every circle by the cutting rotating shaft 61 and is combined once.
