Opto-electronic plate aligner for roller type heat sealing blister packaging machine

The utility model discloses a photoelectric type-matching device of a roller heat-sealing blister packaging machine. Its main features are that a photoelectric eye (13) is arranged above a roller die (15), a photoelectric eye and a rotary encoder (5) And the frequency converter (9) is electrically connected with the programmable controller (10), the frequency converter is electrically connected with the low speed motor, the gear on the rotary encoder meshes with the gear (8) on the main shaft of the packaging machine, and the difference is The planetary gear mechanism is connected with the mesh roller (14) via an overrunning clutch. The utility model conveys the position and speed data of aluminum foil (PTP) movement to a programmable controller (PLC) through a photoelectric eye, and rotates the polyvinyl chloride hard sheet (PVC) on the roller die and the roller die through a rotary encoder. The speed and position are also fed to the programmable controller. After comparing the two sets of data with the original data, the instructions sent by the programmable controller are used to control the operation of the low-speed motor via the inverter to achieve the purpose of the version.
