Description

Technical Field

[0001] This utility model relates to the field of refrigerator door technology, specifically to a refrigerator door sliding structure. Background Technology

[0002] Bending and flattening are common steps in refrigerator door manufacturing, especially when optimizing the appearance and enhancing the functionality of the door panel. The purpose of U-bending is to provide extra strength to the edges or frame of the refrigerator door and to lay a good foundation for subsequent processing such as flattening and finishing. U-bending is usually done on metal sheets such as stainless steel or aluminum alloy, which can enhance the rigidity of the door and prevent deformation.

[0003] In the current refrigerator door manufacturing process, the edges are typically bent to enhance the door's rigidity. However, secondary processing is usually required after bending, necessitating a flattening structure to improve the flatness of the bent area. Existing flattening equipment typically requires manual unloading by workers after flattening, a method that is inefficient, increases labor intensity, and raises labor costs. Utility Model Content

The flattening component 7 is fixedly connected to one side of the support column 6. The support column 6 is fixed to one side of the support shell 1, which facilitates the fixed installation of the flattening component 7. The flattening component 7 includes a cylinder 701, which is fixed to one side of the support column 6. A retaining shell is fixedly connected to the output end of the cylinder 701. 702, a push plate 703 is fixedly connected to one side of the retaining shell 702, a cylinder 701 is fixed to one side of the support column 6, the output end of the cylinder 701 is fixedly connected to the retaining shell 702, a push plate 703 is fixedly connected to one side of the retaining shell 702, and the included angle of the push plate 703 matches the edge of the support shell 1, and sliders 704 are fixedly connected to the front and rear sides of the bottom of the retaining shell 702. The support column 6 has a sliding groove 705 for use with the slider 704. When the user needs to flatten the corner of the door panel, the cylinder 701 can be driven. The piston end of the cylinder 701 drives the retaining shell 702 and the slider 704 to move within the sliding groove 705. As the retaining shell 702 moves, the push plate 703 will fit against the edge of the support shell 1, thereby achieving L-shaped pressing and facilitating secondary flattening of the door panel.

[0024] A limiting shell 8 is set at the top of the inner cavity of the support shell 1. A conveying component 9 is fixedly connected to one side of the limiting shell 8. The conveying component 9 includes a first motor 901 and a fixing plate 902. An auxiliary component 10 is fixedly connected to the top of the pressure plate 4. The auxiliary component 10 includes a second motor 1001 and a fixing plate 1002. Fixing rods 15 that penetrate to the outside of the positioning plate 3 are fixedly connected to both sides of the top of the pressure plate 4. The limiting shell 8 facilitates the fixing of the conveying component 9, and the conveying component 9 can assist in the conveying of the flattened plate. The fixing rods 15 are fixed to the top of the pressure plate 4, so that the pressure plate 4 can play a limiting role when moving up and down.

[0025] A reinforcing block 11 is fixedly connected to one side of the positioning plate 3. The reinforcing block 11 is fixed between the positioning plate 3 and the support frame 2, which can improve the connection strength between the two. One side of the reinforcing block 11 is fixedly connected to the support frame 2. A second hydraulic rod 12 is fixedly connected to the top of the inner cavity of the support shell 1. The top of the second hydraulic rod 12 is fixedly connected to the limiting shell 8. Limiting plates 13 are fixedly connected to the front and rear sides of the bottom of the limiting shell 8. The limiting shell 8 can be adjusted up and down by fixing the second hydraulic rod 12 to the top of the limiting shell 8. A sliding rod 14 is slidably connected inside the limiting plate 13. The sliding connection between the limiting plate 13 and the sliding rod 14 can limit the movement path of the limiting shell 8 and ensure its movement stability. The bottom of the sliding rod 14 is fixedly connected to the support shell 1.

[0026] The first motor 901 is fixed to one side of the limiting shell 8, and the fixing plate 902 is fixed inside the limiting shell 8. The output end of the first motor 901 extends into the interior of the limiting shell 8 and is fixedly connected to the first meshing roller 903. The end of the first meshing roller 903 away from the first motor 901 is rotatably connected to the inner wall of the limiting shell 8 through a bearing. The surface of the first meshing roller 903 is meshed with the conveyor belt 904. One side of the inside of the conveyor belt 904 is meshed with the second meshing roller 905. Both ends of the second meshing roller 905 are rotatably connected to the inner wall of the limiting shell 8 through bearings. By turning on the first motor 901, the first meshing roller 903 can drive the conveyor belt 904 to rotate. As the conveyor belt 904 rotates, it will mesh with the second meshing roller 905 to rotate. At this time, the conveyor belt 904 will be driven to rotate to one side. Then, the second hydraulic rod 12 is opened to make the limiting shell 8 move up and down, so that the top of the conveyor belt 904 exceeds the horizontal plane of the top of the support shell 1 and contacts the bottom of the door panel, thereby performing conveying.

[0027] The second motor 1001 is fixed to the top of the pressure plate 4, and the fixing plate 1002 is fixed to the four corners of the bottom of the pressure plate 4. The output end of the second motor 1001 extends through to the bottom of the pressure plate 4 and is fixedly connected to the first bevel gear 1003. A second bevel gear 1004 is meshed with one side of the first bevel gear 1003. A first rotating rod 1005 is fixedly connected inside the second bevel gear 1004. One end of the first rotating rod 1005 extends through to the outside of the fixing plate 1002 and is fixedly connected to the third meshing roller 1006. A transmission belt 1007 is meshed with the surface of the third meshing roller 1006. A fourth meshing roller 1008 is meshed with the side of the transmission belt 1007 away from the third meshing roller 1006. A second rotating rod 1009 extending through to one side of the fixing plate 1002 is fixedly connected to one side of the fourth meshing roller 1008. One end of the second rotating rod 1009 is connected to the fixing plate 1002 via a bearing. 02 Rotary connection: The first rotating rod 1005 and the second rotating rod 1009 are respectively fixedly connected to the two sides of the surface of the two rods. By turning on the second motor 1001, the first bevel gear 1003 is rotated. As the first bevel gear 1003 rotates, it will mesh with the second bevel gear 1004. When the second bevel gear 1004 rotates, it will drive the first rotating rod 1005 to rotate on the fixed plate 1002. However, when the first rotating rod 1005 rotates, it will drive the third meshing roller 1006 to mesh with the transmission belt 1007 to rotate. As the transmission belt 1007 rotates, it will mesh with the fourth meshing roller 1008 to make the second rotating rod 1009 rotate. At this time, the first rotating rod 1005 and the second rotating rod 1009 will synchronously drive the pressure roller 1010 to rotate and press against the door panel for synchronous conveying. At the same time, it can also drive the piston end of the first hydraulic rod 5 to lower the pressure plate 4 to press against the door panel to ensure the stability of the push-up.

[0028] Working principle: When the user needs to flatten the corner of the bent refrigerator door panel, the refrigerator door panel can be placed on top of the support shell 1. Then, by driving the second hydraulic rod 12, the limiting shell 8 is raised, causing the conveyor 9 to move upward. Turning on the first motor 901 causes the first meshing roller 903 to drive the conveyor belt 904 to rotate. As the conveyor belt 904 rotates, it engages with the second meshing roller 905, causing the conveyor belt 904 to move to one side. At this point, opening the second hydraulic rod 12 raises the limiting shell 8, causing the top of the conveyor belt 904 to extend beyond the support shell. The top horizontal plane contacts the bottom of the door panel, thus conveying it to the middle position of the support shell 1 and placing the door panel between the two push plates 703. Then, the drive of the first motor 901 is stopped, and the second hydraulic rod 12 is reset to make the conveyor belt 904 detach from the refrigerator door panel. Subsequently, the cylinder 701 is driven, and the piston end of the cylinder 701 drives the fixed shell 702 and the slider 704 to move within the slide groove 705. As the fixed shell 702 moves, it causes the push plate 703 to fit against the edge of the support shell 1, thereby achieving L-shaped pressing and pressing the corner of the door panel. After the refrigerator door panel corners are flattened, the second hydraulic rod 12 is raised again, contacting the bottom of the door panel via the conveyor belt 904. Then, the first motor 901 is driven again, simultaneously driving the piston end of the first hydraulic rod 5 to lower the pressure plate 4. Subsequently, the second motor 1001 is turned on, causing the first bevel gear 1003 to rotate. As the first bevel gear 1003 rotates, it meshes with the second bevel gear 1004. The rotation of the second bevel gear 1004 drives the first rotating rod 1005 to rotate on the fixed plate 1002. However, during the first rotation… When the moving rod 1005 rotates, it drives the third meshing roller 1006 to mesh with the transmission belt 1007. As the transmission belt 1007 rotates, it meshes with the fourth meshing roller 1008, causing the second rotating rod 1009 to rotate. At this time, the first rotating rod 1005 and the second rotating rod 1009 will synchronously drive the pressure roller 1010 to rotate and press against the refrigerator door panel for synchronous conveying, thereby ensuring the stability of the conveying. At the same time, the pressure roller 1010 can also be lowered to cooperate with the fixing plate 902 to press against the door panel, so as to ensure that the corner of the refrigerator door panel will not be misaligned when it is pushed flat.
