Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to a non-deviation automatic tracking punching and discharging mechanism. Background Art

[0002] Most medicines are packaged using aluminum-plastic blister packaging machines. The working principle of aluminum-plastic blister packaging machines is as follows: 1. Feeding and conveying: First, the product to be packaged is fed into the conveyor belt inside the machine, and the conveyor belt automatically moves the product downward; 2. Plastic blister molding: Above the conveyor belt, there is a heat sealer, which slowly heats the plastic film to soften it and form it. Then, the blister mold will absorb the hot and soft plastic film onto the blister mold and form it into a blister; 3. Adding the aluminum-plastic composite film: After the blister is formed, it will be rotated to the other side through the turntable, and the aluminum-plastic composite film will be added at this time to seal the composite film to the outside of the plastic blister; 4. Heat sealing: The heat sealing head compacts the gap between the aluminum-plastic composite film and the blister mold, and heats it at the same time to heat the aluminum-plastic film and the plastic blister; 5. Punching: After the heat sealing is completed, the guide rod is automatically fed in, the blister mold is pressed with the guide rod, and then the punching between the aluminum-plastic film and the blister is completed by the cutting device; 6. Product discharge: After the punching is completed, the product is discharged from the aluminum-plastic blister packaging machine through the discharge conveyor belt.

[0003] The problem existing in the operation of this equipment is that the plastic blister forming station slowly heats the plastic film to soften it and form it. The temperature of this state is relatively high, and the length of the plastic blister will not change during the continuous output process. Once the machine is stopped and a period of time has passed, the temperature of the plastic blister drops. Due to thermal expansion and contraction, the length of the plastic blister will shrink due to the temperature drop, resulting in the failure of the subsequent heat sealing station and punching station to calibrate the original position after restarting, especially in the punching station, which cannot correspond to the mold cavity, resulting in misaligned cutting. At this time, a large number of unqualified finished products with inadequate heat sealing and inaccurate slitting will appear, requiring a lot of time for manual screening, bringing inconvenience and loss to production. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a non-biased automatic tracking punching and unloading mechanism, which aims to automatically adjust the positions of the heat sealing station and the punching station according to the state of the blister conveying, so as to avoid punching out unqualified finished products when the formed blister expands and contracts due to thermal expansion and contraction.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-deviation automatic tracking punching and unloading mechanism, comprising a base, a heat sealing station and a punching station are installed on the base, grating displacement sensors are installed on the heat sealing station and the punching station respectively, and also comprises a control processor, a first servo motor and a second servo motor, the two grating displacement sensors are conductively connected to the control processor, the first servo motor and the second servo motor are controlled and connected by the control processor, a first guide rail and a second guide rail are arranged on the base, a first slide seat sliding along the first guide rail is arranged at the bottom of the heat sealing station, and a second slide seat sliding along the second guide rail is arranged at the bottom of the punching station, the movement of the heat sealing station on the first guide rail is driven by the first servo motor, and the movement of the punching station on the second guide rail is driven by the second servo motor.

[0006] A first threaded sleeve is connected to the side end of the heat sealing station, a first threaded rod threadedly connected to the first threaded sleeve is arranged on the base, a first servo motor is connected to the base, and an output shaft of the first servo motor is connected to the first threaded rod.

[0007] A second threaded sleeve is connected to the side end of the punching station, a second threaded rod threadedly connected to the second threaded sleeve is arranged on the base, a second servo motor is connected to the base, and an output shaft of the second servo motor is connected to the second threaded rod.

[0008] The beneficial effects of the utility model are as follows: the grating displacement sensor can be used to detect whether the transverse indentations of the formed blisters passing through are aligned, and the grating displacement sensor transmits the detected signal to the control processor for processing. When it is not aligned, the control processor can control and calibrate the first servo motor and / or the second servo motor to achieve the purpose of tracking punching. When aligned, the heat sealing station and the punching station can proceed normally, so that the positions of the heat sealing station and the punching station are automatically adjusted according to the state of the blister conveying, so as to avoid punching out unqualified finished products when the formed blisters expand and contract due to thermal expansion and contraction.
