Description

Technical Field

[0001] The utility model belongs to the technical field of folder manufacturing equipment, and particularly relates to a folder corner protection device. Background Art

[0002] A folder is a tool for processing documents. When organizing materials in some office areas, folders are usually used, which facilitates the organization of text materials and improves the efficiency of organizing text materials. Folders are usually made of plastic sheets.

[0003] During the use of the folder, since the folder is made of cardboard, during the long-term use of the folder, the corners are prone to damage due to bumps. To prevent the folder from being damaged, corner protectors are usually installed at the corners to avoid damaging the folder during bumps. The installation of the corner protectors usually requires manual pre-insertion of the corner protectors at the corners of the folder, and then compressing them with a punching tool. This processing method has extremely low efficiency, and the punching tool is prone to pose a danger to the operating employees. Summary of the Invention

Detailed Embodiment

[0011] The technical solution of the present utility model will be further specifically described below through embodiments and in combination with the drawings.

[0012] Embodiment: A folder corner guard device, as Figure 1As shown in the figure, it includes a carrier plate 1. In the middle position at the right end of the upper surface of the carrier plate 1, there is a feeding plate 2. At the positions corresponding to the four corners of the feeding plate 2 on the carrier plate 1, there is a set of corner protection positioning cylinders respectively. Each set of corner protection positioning cylinders includes two positioning cylinders 3. The two positioning cylinders 3 are arranged perpendicular to each other, and the extending ends face the side of the feeding plate 2. On the extending ends of the positioning cylinders 3, there is a top bracket 4 respectively. Above each set of corner protection positioning cylinders, there is a stamping cylinder 5. On the extending end of each stamping cylinder 5, there is a hammer block 6. On the front and back sides at the right end of the carrier plate 1, there is a set of feeding mechanisms respectively. The two sets of feeding mechanisms are aligned with the feeding plate 2 and are at the same distance from the feeding plate 2. The feeding mechanism includes a horizontal ejecting cylinder 7, a first longitudinal ejecting cylinder 8 and two feeding platforms 9. The distance between the two feeding platforms 9 is the same as that of the two sets of corner protection positioning cylinders on the same side. The extending end of the first longitudinal ejecting cylinder 8 is connected to the extending end of the horizontal ejecting cylinder 7. On the extending end of the first longitudinal ejecting cylinder 8, there is a first lifting frame 10.
