[0044] Refer to Figures 1 to 5 , which is an embodiment of the present invention, a device for producing U-shaped paper corner protectors 6 is proposed, which is used to stamp a paper coil into a paper corner protector 6, including: a frame 1; a stamping member 2, arranged on the frame 1, and the stamping member 2 is used to stamp the paper coil into a paper corner protector 6; a cutting member 3, arranged on the frame 1, and the stamping member 2 is located at the discharge end of the stamping member 2, and the cutting member 3 is used to cut the paper corner protector 6 into sections; a limiting pressing plate 4, arranged on the frame 1 in a lifting manner, and the limiting pressing plate 4 is located above the cutting member 3; a plurality of limiting rods 8, all of the plurality of limiting rods 8 are slidably arranged on the limiting pressing plate 4, and the limiting pressing rod has a roller 10, and the roller 10 abuts against the side wall of the paper corner protector 6.
[0045] In the above solution, the frame 1 serves as the support structure of the entire device, used to carry and fix other components. The stamping part 2 is arranged on the frame 1 and is used to stamp the paper coil into the paper corner protector 6. The cutting part 3 is arranged on the frame 1 and is located at the discharge end of the stamping part 2, and is used to cut the formed paper corner protector 6 into segments according to the required length. The limiting pressure plate 4 is arranged on the frame 1 in a lifting manner and is located above the cutting part 3. It is used to apply appropriate pressure to the side wall of the paper corner protector 6 during the cutting process to prevent the side wall of the paper corner protector 6 from deforming, and at the same time, it can also gently cover the top surface of the paper corner protector 6 during cutting to prevent the paper corner protector 6 from warping in the length direction during cutting, thereby affecting the subsequent cutting work. There are several limiting rods 8, and several limiting rods 8 are all slidably arranged on the limiting pressure plate 4. A roller 10 is installed on the limiting rod 8, and the roller 10 abuts against the side wall of the paper corner protector 6 to provide additional support for the side wall of the paper corner protector 6, ensuring the stability of the side wall during the cutting process and avoiding bending deformation.
[0046] Working principle: During the production process of the paper corner protector 6, the paper coil is first stamped into a U-shaped paper corner protector 6 by the stamping part 2. Subsequently, under the combined action of the limiting pressure plate 4 and the limiting rods 8, the paper corner protector 6 is cut by the cutting part 3. The limiting pressure plate 4 applies appropriate pressure during the cutting process to ensure smooth and uniform cutting. At the same time, the roller 10 on the limiting rod 8 abuts against the side wall of the paper corner protector 6 to provide support for the side wall and avoid bending deformation during the cutting process, ensuring high-quality finished products. This embodiment can significantly improve the cutting flatness and uniformity of the paper corner protector 6, and at the same time effectively prevent the bending deformation of the side wall of the paper corner protector 6 during the cutting process, greatly improving the product quality of the U-shaped paper corner protector 6.
[0047] Further, the limiting pressure plate 4 has several sliding grooves 401, and several sliding grooves 401 are arranged in a ring around the center of the limiting pressure plate 4 on the limiting pressure plate 4; the first end 801 of each limiting rod 8 is hinged to the limiting pressure plate 4, the second end 802 extends out of the limiting pressure plate 4, the roller 10 is arranged on the second end 802 of the limiting rod 8, and the third end 803 of the limiting rod 8 is slidably arranged in the sliding groove 401.
[0048] In the above solution, the limiting pressure plate 4 has several sliding grooves 401, and these sliding grooves 401 are arranged in a ring around the center of the limiting pressure plate 4, ensuring that the limiting rod 8 can slide and then clamp or release the side wall of the paper corner protector 6, providing uniform and stable support for the side wall of the paper corner protector 6. The first end 801 of each limiting rod 8 is hinged to the limiting pressure plate 4, allowing the limiting rod 8 to swing within a certain range to adapt to different thicknesses and shapes of the paper corner protector 6. The second end 802 extends out of the limiting pressure plate 4, and the roller 10 is arranged at the second end 802 for abutting against the side wall of the paper corner protector 6. The third end 803 is slidably arranged in the sliding groove 401 to ensure the stable sliding of the limiting rod 8 and avoid deviation or jamming during the working process.
[0049] Working principle: During the cutting process of the paper corner protector 6, the limiting pressure plate 4 descends, and the limiting rod 8 slides along the sliding groove 401 until the rotating roller 10 abuts against the side wall of the paper corner protector 6. The rotating roller 10 closely fits the side wall of the paper corner protector 6. Even when facing paper corner protectors 6 with different thicknesses or shapes, it can provide uniform supporting force, prevent the side wall from bending and deforming during cutting, ensure the flatness of cutting and the overall quality of the paper corner protector 6. This embodiment improves the supporting effect of the side wall during the cutting process, ensures the flatness and uniformity of the cutting of the paper corner protector 6, avoids the bending deformation of the side wall after cutting, and significantly improves the product quality of the U-shaped paper corner protector 6.
[0050] Furthermore, the rotating roller 10 is conical or cylindrical, and the outer wall of the rotating roller 10 is in sliding or rolling abutment with the side wall of the paper corner protector 6.
[0051] In the above solution, the conical rotating roller 10 can better adapt to the side walls of paper corner protectors 6 with different thicknesses, ensure uniform supporting force during cutting, reduce the bending deformation of the side wall. By excessively squeezing the side wall of the paper corner protector 6 with the conical rotating roller 10, when the side wall of the paper corner protector 6 rebounds, it can just rebound to an angle perpendicular to the bottom surface. The cylindrical rotating roller 10 is suitable for paper corner protectors 6 with relatively uniform thickness and provides stable and consistent support. The outer wall of the rotating roller 10 is in sliding or rolling abutment with the side wall of the paper corner protector 6. The sliding contact method is suitable for the situation where the side wall of the paper corner protector 6 is relatively rough or has slight deformation. Through sliding contact, the rotating roller 10 can better adapt to the irregular shape of the side wall and provide targeted support. The rolling contact method reduces the friction of the contact surface, reduces the damage to the side wall of the paper corner protector 6 during cutting, and improves the flatness of cutting and the integrity of the side wall.
[0052] Furthermore, it further includes: pressing plates 11, there are several of them, and several pressing plates 11 are all arranged on the limiting pressure plate 4, and the side of the pressing plate 11 away from the limiting pressure plate 4 is in sliding abutment with the inner bottom surface of the paper corner protector 6.
[0053] In the above solution, the pressing plates 11 are evenly arranged on the limiting pressure plate 4 to ensure uniform support and pressing on the inner bottom surface of the paper corner protector 6, and avoid the paper corner protector 6 from warping during cutting. The side of the pressing plate 11 away from the limiting pressure plate 4 is in sliding abutment with the inner bottom surface of the paper corner protector 6. During the cutting process, as the limiting pressure plate 4 descends, the pressing plate 11 contacts the inner bottom surface of the paper corner protector 6, and through the way of sliding abutment, ensures the stability of the paper corner protector 6 during cutting, reduces the deformation after cutting, and improves the flatness and consistency of the finished product.
[0054] Further, the cutting member 3 includes: a frame 301 disposed on the frame 1; a carrier table 302 disposed on the frame 1 and located within the frame 301. The bottom and side surfaces of the carrier table 302 are each provided with a cutting groove 3021, and the top surface of the carrier table 302 is provided with a receiving groove 3033 for receiving the paper corner protector 6 after stamping. The cutting knives 303 are provided in several numbers, and each cutting knife 303 faces a cutting groove 3021. The several cutting knives 303 are used to simultaneously cut the bottom and side surfaces of the paper corner protector 6.
[0055] In the above solution, the frame 301 is disposed on the frame 1, providing a stable support and positioning for the cutting member 3. The carrier table 302 is disposed on the frame 1 and located within the frame 301. The bottom and side surfaces of the carrier table 302 are each provided with a cutting groove 3021 for guiding the cutting knives 303 to perform precise cutting. The top surface of the carrier table 302 is provided with a receiving groove 3033 for receiving the paper corner protector 6 after stamping and transportation, ensuring the fixed position of the paper corner protector 6 during the cutting process and avoiding inaccurate cutting caused by position deviation. Each cutting knife 303 faces a cutting groove 3021, enabling multiple cutting knives 303 to simultaneously cut the bottom and side surfaces of the paper corner protector 6, improving the cutting efficiency and ensuring the synchronization and consistency of cutting, and avoiding deformation or dimensional deviation of the paper corner protector 6 caused by uneven cutting force during the cutting process.
[0056] Further, it further includes: a guide plate 7 disposed on the frame 1 and located on the side of the carrier table 302 away from the stamping member 2. The guide plate 7 has a guide groove 701; a collection box 5 slidably disposed on the frame 1. The collection box 5 is located below the guide plate 7. After the cutting knives 303 cut the paper corner protector 6, the guide groove 701 guides the paper corner protector 6 into the collection box 5.
[0057] In the above solution, the function of the guide groove 701 is to guide the cut paper corner protector 6 to slide along a predetermined path after the cutting knives 303 complete the cutting, ensuring that the paper corner protector 6 can smoothly and orderly enter the next process or collection link, and avoiding the chaotic stacking of the cut paper corner protector 6. The collection box 5 is slidably disposed on the frame 1 and is located below the guide plate 7. By horizontally moving the collection box 5, the paper corner protector 6 can be evenly placed into the collection box 5.
[0058] Further, a notch 702 is provided on the side wall of the guide plate 7, and the notch 702 is used to provide a moving space for the swinging of the limiting rod 8.
[0059] Further, it further includes: a material tray 12 rotatably disposed on the frame 1. A paper coil is detachably disposed on the material tray 12.

[0060] Further, the stamping part 2 includes: a plurality of pressing rollers 13, which are rotatably arranged on the frame 1 at intervals, and the pressing rollers 13 are used to extrude the paper coil into the paper corner protector 6.
[0061] In the above solution, during the forming process of the paper corner protector 6, the paper coil first passes through the pressing rollers 13 arranged at intervals. The pressing rollers 13 apply a directional pressure to the paper coil by rotating, causing the paper coil to deform when passing through the gap between the pressing rollers 13, and forming the paper corner protector 6 with a predetermined shape. The spaced layout and rotational design of the plurality of pressing rollers 13 ensure uniform stress on the paper coil during the forming process.
[0062] Further, it further includes: a hydraulic rod 9, which is arranged on the frame 301. The hydraulic rod 9 has a movable end, and the movable end is arranged on the limiting pressing plate 4. The hydraulic rod 9 is used to drive the limiting pressing plate 4 to move up and down.
