[0002] Paper corner protectors are an environmentally friendly packaging material made from multiple layers of kraft paper or recycled paper through a special process. They are mainly used to protect the edges of goods and enhance the structural strength of packaging, and are widely used in logistics, warehousing, and industrial packaging.

[0003] Currently, in the production process of long L-shaped paper corner protectors, a corner protector slitting device is required to cut the continuously produced paper corner protectors according to the preset size for easy subsequent use; Currently, long L-shaped paper corner protectors are typically fed via conveyor belts before cutting. However, during this process, it's difficult to ensure that the L-shaped paper corner protectors are centered on the conveyor belt, resulting in tilted corner protectors. Consequently, the cut surface is often beveled, leading to poor cutting accuracy. Furthermore, the conveyor belts cannot effectively provide internal support during cutting, causing the corner protectors to deform easily and affecting the quality of the finished product. Therefore, we have proposed a corner protector slitting device for paper corner protector production lines. Utility Model Content

[0026] like Figures 1-5As shown, it illustrates a corner protector slitting device for a paper corner protector production line according to an embodiment of the present invention, including a feeding rack 1, a conveyor belt 2 on the feeding rack 1, an L-shaped paper corner protector 3 on the conveyor belt 2, an mounting frame 4 at one end of the feeding rack 1, a cutting mechanism 5 on the mounting frame 4, the cutting mechanism 5 including a first inner support 503 and a second inner support 504, the first inner support 503 being disposed inside the mounting frame 4 away from the end of the conveyor belt 2, and the second inner support 504 being disposed inside the mounting frame 4 near the end of the conveyor belt 2; Both the material conveyor 1 and the mounting frame 4 are equipped with a limiting structure 6. The limiting structure 6 includes a U-shaped frame 601, a limiting post 602 and a ball bearing 603. There are two limiting posts 602, which are respectively located at both ends of the upper wall of the U-shaped frame 601. The ball bearing 603 is rotatably located at the lower end of the limiting post 602.

[0027] This embodiment provides a corner protector slitting device for a paper corner protector production line, which, through the arrangement of a material conveyor 1, a conveyor belt 2, a first inner support frame 503, a second inner support frame 504, a guide block 505, a U-shaped frame 601, a limiting post 602, and a ball bearing 603, ensures that the L-shaped paper corner protector 3 moves along the upper surface of the conveyor belt 2. The ball bearing 603 contacts the outer wall of the L-shaped paper corner protector 3, effectively limiting its movement and ensuring that the paper corner protector moves to the center of the upper surface of the conveyor belt 2. When the L-shaped paper corner protector 3 moves to the outer surface of the first inner support frame 503 and the second inner support frame 504, the first inner support frame 503 and the second inner support frame 504 effectively provide internal support for the paper corner protector during cutting. Combined with the limiting structure 6, this effectively ensures the quality of the cut product.

[0028] See in some examples Figure 1 and Figure 4 The cutting mechanism 5 also includes a hydraulic cylinder 501, a cutting blade 502, and a guide block 505. The hydraulic cylinder 501 is located on the upper end of the mounting bracket 4.

[0029] In the above structure, the mounting bracket 4 facilitates the installation of the cutting mechanism 5. The hydraulic cylinder 501 works to effectively drive the cutting blade 502 to move up and down via the piston rod.

[0030] Further as Figure 4 As shown, the guide block 505 is located on the side of the second inner support 504 away from the first inner support 503. The guide block 505 is located above the conveyor belt 2. The gap between the first inner support 503 and the second inner support 504 is a cutter clearance groove.

[0031] In the above structure, the guide block 505 can effectively guide the paper corner protector, guiding it to move to the outer surface of the first inner support frame 503 and the second inner support frame 504. During cutting, the first inner support frame 503 and the second inner support frame 504 can effectively provide internal support for the paper corner protector. In conjunction with the limiting structure 6, the quality of the cut product can be effectively guaranteed.

[0032] In a preferred embodiment, the limiting structure 6 further includes a connecting plate 604, an adjusting screw 605, and a knob 606. Sliding holes are provided at both ends of the upper wall of the U-shaped frame 601.

[0033] In the above structure, by rotating the knob 606, the adjusting screw 605 can be effectively driven to rotate synchronously. Then, under the limiting action of the limiting post 602, the connecting plate 604 can move up and down in the vertical direction along the adjusting screw 605. The connecting plate 604 can drive the ball bearings 603 to move up and down synchronously through the limiting post 602. When both balls 603 are in contact with the outer wall of the paper corner protector, the paper corner protector can be effectively limited, ensuring that the paper corner protector moves at the center of the upper surface of the conveyor belt 2. The overall operation is simple and ensures cutting accuracy.

[0034] In a preferred embodiment, a receiving rack 7 is provided on the side of the mounting frame 4 away from the material conveying rack 1. The receiving rack 7 includes a base 701, side baffles 702 and front baffles 703. The side baffles 702 are provided on both sides of the base 701, and the front baffles 703 are provided at the front end of the base 701. The end of the base 701 is connected to the mounting frame 4 through a vertical plate.

[0035] In the above structure, the cut paper corner protectors can be pushed into the receiving rack 7. When the paper corner protectors in the receiving rack 7 reach a certain height, they can be taken out in a concentrated manner, which is convenient for the next step of packaging. The operation is simple and saves time and effort.

[0036] In a preferred embodiment, support legs 101 are provided at both ends of the lower surface of the material conveyor 1.

[0037] In the above structure, the support legs 101 can effectively support the material conveying frame 1 and ensure the overall stability.

[0038] Working principle: Rotating the knob 606 can effectively drive the adjusting screw 605 to rotate synchronously. Then, under the limiting action of the limiting post 602, the connecting plate 604 can move up and down in the vertical direction along the adjusting screw 605. The connecting plate 604 can drive the ball bearings 603 to move up and down synchronously through the limiting post 602. When both balls 603 are in contact with the outer wall of the L-shaped paper corner protector 3, the L-shaped paper corner protector 3 can be effectively limited, ensuring that the L-shaped paper corner protector 3 moves at the center of the upper surface of the conveyor belt 2. The overall operation is simple and ensures cutting accuracy.

[0039] Furthermore, the guide block 505 can effectively guide the paper corner protector, guiding it to move to the outer surface of the first inner support frame 503 and the second inner support frame 504. During cutting, the first inner support frame 503 and the second inner support frame 504 can effectively support the L-shaped paper corner protector 3. Combined with the limiting structure 6, the quality of the cut product can be effectively guaranteed. The cut paper corner protectors can be pushed into the receiving rack 7. Once the L-shaped paper corner protectors 3 in the receiving rack 7 reach a certain height, they can be taken out in one go for easy packaging. The operation is simple, time-saving and labor-saving.
