Description

Technical Field

[0001] The utility model relates to a sealing and packaging technology for medical devices, in particular to a transmission system of a blister sealing machine. Background Art

[0002] Medical devices generally need to be packaged after they are produced, especially some small-sized devices that need to be sterilized and packaged before being delivered to the end user. Plastic sealing is a common packaging method. Its common operation process is to first blister the plastic film into a soft blister box with a concave shape in the middle, which is suitable for placing the medical device to be packaged; then place the medical device to be packaged and sealed in the concave shape; then cover the soft blister box with a cover material; finally, fuse the cover material and the soft blister box together. In this way, the medical device to be packaged is sealed in the cover material and the blister box, thereby completing the packaging of the medical device.

[0003] In the continuous production of the blister sealing machine, the blister box forming and blister box sealing are carried out simultaneously at different positions. The plastic film and cover material will be continuously transmitted for a fixed distance, then stop for a while, and then transmit a fixed distance again after the blister box forming and blister box sealing are completed, and so on and so forth until all the medical devices to be packaged are packaged. Since the plastic film and cover material are both soft materials and are not easy to position, the start and stop during the transmission process will cause certain errors. The continuous accumulation of errors will cause the blister box to fail to be transmitted to the specified position and the line has to be stopped to readjust the equipment, resulting in material waste and reduced production efficiency.

[0004] Based on this, a transmission system of the utility model is specially proposed to ensure that the transmission distance of the blister film and the cover material is consistent each time, avoid excessive shutdown adjustments, improve production efficiency, and reduce waste of raw materials.
