[0002] Corner protectors, as the name implies, are protective corners. They are often used in the packaging field to protect the corners of products. Products are inevitably bumped during transportation. At this time, wrapping the product with corner protectors can greatly reduce damage to the product and improve product safety. Corner protectors used for product packaging generally use paper corner protectors and plastic corner protectors. During production, paper corner protectors generally place rolled strips on a feeder, and a certain number of rolls are fed simultaneously using the required number of corner protection layers.

[0024] In this embodiment, when in use, the material strip roll is first placed on the second support member 11 on the weighing rod, and then the limit member 10 is used to release the limit on the positioning rod 5 and pull the positioning rod 5, so that the positioning rod 5 is rotated on the support plate 2 through the support ring 4 until the positioning rod 5 is rotated to conflict with the blocking rod 9, and then the hole in the center of the material strip roll is passed through the limit plate 8 and sleeved on the insertion rod 7, wherein the sum of the lengths of the end of the insertion rod 7 and the limit plate 8 is smaller than the diameter of the hole in the center of the material strip roll, and then the positioning rod 5 is rotated again, so that the positioning rod 5 is rotated to the top of the load-bearing rod 3, and is limited by the limit member 10, and the limit plate 8 will limit the material strip roll to prevent it from slipping, thereby finally achieving a compact structure, reducing the footprint of the feeding device, reducing the number of feeding devices required for producing paper corner protectors, and reducing the production cost of producing paper corner protectors.

[0032] In this embodiment, the supporting plate 24 is positioned by the screw 25. When the strip roll needs to be placed, the bevel gear rod 27 can be rotated to drive the bevel gear head 26 and the screw 25 to rotate. As the screw 25 rotates, the supporting plate 24 will be driven to move downward.
