Description

Technical Field

[0001] The utility model relates to the technical field related to packaging sheets, and in particular to a packaging sheet receiving device. Background Art

[0002] For conventional electronic products such as circuit boards, sheets are often used for appropriate packaging. PET sheets are the most common ones, and the packaging sheets need to be rolled up during the processing.

[0003] After massive searches, it was found that the existing Chinese patent publication number is CN218619365U, which discloses a sheet winding device for blister packaging, involving blister sheet processing, including a first support, a second support and a winding tube. The first support and the second support are both provided with a clamping component for clamping and limiting the two ends of the winding tube. The clamping component includes an insert tube, a limiting ring installed on the insert tube, and an abutment block connected to the insert tube in a circular sliding manner. The device can enable the clamping components on the first support and the second support to clamp and fix the two ends of the winding tube through the coordination of the clamping component, the rotating component and the adjusting component, and rotate the winding tube fixed on the clamping component, thereby achieving the effect of winding the blister sheet. The distance between the first support and the second support and the winding tube is adjusted by the adjusting component. It is not only suitable for winding tubes of different lengths, but also convenient for replacing the winding tube, thereby improving the winding and packaging efficiency of the blister sheet.
