[0033] Working principle:

[0034] Movement in height direction: 30-servo motor I drives the two 14-drive shafts on the top beam to rotate through 17-coupling III, and then drives the two 7-screws I on the left and right columns to rotate through 12-right-angle steering gear. The rotation of 7-screw I will drive the 8-screw slider I to rise and fall in the height direction, and then drive the 4-beam to rise and fall in the height direction. Compared with two servo motors driving the left and right column screws separately, the method of driving the left and right column screws to rotate simultaneously by one servo motor can ensure the consistency of the lifting height of the left and right ends of the beam to a greater extent.

[0035] Material width direction (attached Figure 1 Movement in the left and right directions): 18-Servo motor II drives 23-screw II to rotate through 20-coupling IV, so as to realize the movement of 24-screw slider along the material width direction, and then drives 40-glue sticking machine to realize the movement along the material width direction.

[0036] Rolling diameter direction (with Figure 3 41 - axial direction of the screw) movement: 35 - servo motor III drives 41 - screw III to rotate through 36 - coupling 5, and the rotation of 41 - screw III drives 38 - screw slider III to move along the axial direction of the screw, and then drives 40 - glue sticking machine to move along the axial direction of the screw.

[0037] Action flow: When gluing, 30-servo motor I controls the crossbeam to move to the specified height and then stop, 18-servo motor II controls the gluing component to move along the material width direction (attached Figure 1 Move in the left and right direction) and stop after moving to the edge of the barrel. At this time, the 35-servo motor controls the glue machine to move in the direction of the roll diameter (attached Figure 3 After reaching the specified position, 18-servo motor II controls the glue sticking component to move along the material width direction (attached Figure 1 The glue sticking machine moves in the left and right directions to glue the material roll. The glue sticking length is controlled by the glue sticking machine. After the glue sticking is completed, the glue sticking assembly moves to the initial position to proceed to the next process of changing the roll.
