Application of PLC control in blister packing machine

PLC control of traction part

According to the calculation, the working stroke of the CAM at the forming and heat sealing parts of the bubble cover is. Push movement time 0.5 seconds, far rest time 1.5 seconds, return movement time 0.5 seconds, near rest time 0.5 seconds.

When the CAM of the shape and heat sealing part is in the state of push motion, the fixed mechanical gas clamp is loosened, the dynamic mechanical gas clamp is clamped, and the PVC sheet is pulled forward. This process is completed by PLC controller to control the opening and closing of the cylinder to complete.

When the CAM is in the far rest position, that is, the whole machine is in the working state, the fixed mechanical gas clamp hand clamped, the dynamic mechanical gas clamp hand loosened, the work part began to work, including the completion of preheating, bubble forming and heat sealing.

When the CAM is in the return movement state, the fixed mechanical gas clamping hand clamping, dynamic mechanical gas clamping hand under the action of the spring force reset.

When the CAM is in the position of near rest, the fixed mechanical gas clip is loosened, the dynamic mechanical gas clip is clamped, and the PVC sheet is pulled forward.

PLC control of waste material dropping part

Because in the middle of the chassis between the bubble cover forming part and the heat sealing part of the waste detection device, when the detection machine found empty shot, will immediately send an electrical signal to the PLC controller, and then the PLC controller issued instructions to control the movement of the cylinder part of the falling, so that the falling valve open, the waste into the waste collector.
