The present utility model discloses a fully automatic mechanical arm lifting shaft surface friction three in one winding machine, which is suitable for blown film machines, casting machines, laminating machines, non-woven fabric production lines, medical breathable films, glue laminating machines, TPU roll laminating machines, and relates to food packaging, building materials medical packaging, daily chemical packaging, and electronic and electrical component packaging.
The advantage lies in having three winding methods: surface friction, gap control, and center winding, which can be switched freely according to the material winding process. It is equipped with automatic flipping and cutting of materials, automatic lifting and reel replacement, online automatic tension control, online slitting function, and online calculation of roll diameter counting function. It runs synchronously with the main equipment, improves production efficiency, and saves manual labor.
The structure is as follows:
The S1 wall panel is fixedly connected by inner pillars and equipped with S2 friction rollers, which are driven and operated by S3-RV motors. S4 flipping knife holders are installed on both sides of the same axis as the rollers. S5 two aluminum rods and S6 rodless cylinder flying knives are installed on the knife holders, and there are two air inlet holes on the vertical lower side of the flipping rack. When changing the coil for cutting, the knife holder stops at the position where the Hall sensor is installed, and there are also two holes on the side aligned with the wall panel. An air inlet solenoid valve is installed, which is electrically controlled by PLC. The air is blown out by the cylinder to align with the two holes, and the flying knife runs left and right for cutting. After cutting is completed, the solenoid valve stops supplying air, the cylinder retracts, and the knife holder flips again, stopping at the reset Hall switch, S6 is the translational winding part, equipped with S7 cylinder, S8 center winding motor mounting plate, S9 synchronous belt mounting S8 part, controlled by S10 motor to measure the friction gap between the material and the large leather roller, S11 unloading part, equipped with S12 cylinder and transmission shaft, S13 robotic arm with a straight top, equipped with S14 robotic arm running rack track and linear track, S15 grasping part equipped with S16 lifting part cylinder and grasping arm S17. S18 deceleration motor runs through a shaft, with gears installed on both sides to cooperate with the gear running forward and backward. S19 pressure sensor is installed on the back of the winding machine to measure the material tension online and automatically control it. S20 cutting part is equipped with linear track, scale, and knife holder for cutting materials. S21 two side covers are installed with electrical control components for cutting materials. Human machine interface, overall structure, elegant and beautiful appearance, convenient transportation, and easy operation.
