Description

Technical Field

[0001] The utility model specifically relates to the technical field of roll collection and replacement, in particular to an automatic roll collection and replacement mechanism for a continuous roll bag. Background Art

[0002] The roll bag currently used in supermarkets is a long bag. Customers place the selected items in the bag. This kind of bag can often be seen in daily life. However, during the processing and production of such roll bags, they need to be rolled up to obtain the roll bags we can see now. However, when the traditional rolling device is rolling up, it effectively rolls up through the winding shaft inside the roll bag. However, the number or quantity of the roll bags on each winding shaft is the same. In this way, when the winding shaft collects the specified number or weight, it is necessary to manually change the roll, which reduces the efficiency of rolling up and changing the roll.

[0004] The reel-reeling and reel-changing device in the above patent reels the plastic film onto a plurality of cross bars when the turntable rotates. When the weight or length of the plastic film on the cross bars reaches the specified axis, the plastic film falls onto the collecting plate below, thereby replacing the reeled cross bars. However, the above patent does not further explain how to replace the reel-reeling, so the technical solution in the above patent still has certain technical defects.
