Nov 19, 2021

The traction part of the capsule blister packaging machine is controlled by PLC. The calculation shows that the working stroke of the cam at the blister forming part and the heat-sealing part is; the stroke movement time is 0.5 seconds, the far rest time is 1.5 seconds, the return movement time is 0.5 seconds, and the near rest The time is 0.5 seconds.

When the forming and heat sealing part of the capsule blister packaging machine is cam, the opening and closing of the cylinder is controlled by the PLC controller. When the cam is in the remote rest position, that is, when the whole machine is in working condition, the mechanical air clamp is fixed and the mechanical air clamp is released, and each working part starts to work, including preheating, blister forming and heat sealing. Finish. When the cam is in the state of return movement, the mechanical air gripper is fixed and the mechanical air gripper is reset under the action of the spring force. When the cam is in the near rest position, the fixed mechanical air gripper is released, and the mechanical air gripper is moved to clamp and pull the PVC sheet to move forward.

Since there is a waste detection device between the blister forming part and the heat-sealed part of the capsule blister packaging machine, when the detection machine finds empty pills, it will immediately send an electrical signal to the PLC controller, and then the PLC controller Send a command to control the movement of the cylinder of the blanking part, open the blanking valve, and drop the waste into the waste collector.
