Description

Technical Field

[0001] This utility model relates to the field of shelf processing and polishing technology, specifically to a cutting edge polishing device for cutting metal frames. Background Technology

[0002] Metal frames are structures with metal as their skeleton, widely used in supermarket shelves. A metal frame is composed of multiple rods joined together. During processing, these rods need to be cut to meet usage requirements, and after cutting, a grinding device is used to polish the cut edges to ensure they are smooth and even. However, when using a grinding belt to polish the metal rod cut edges, if the cut edges are significantly uneven, the grinding belt cannot automatically adjust itself, which can easily damage the cut edges and affect the polishing effect.

[0003] Based on this, the present invention designs a cutting edge grinding device for cutting metal frames to solve the above problems. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cutting edge grinding device for cutting metal frames.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutting edge grinding device for cutting metal frames includes an operating table, a placement frame rotatably connected to the top of the operating table, and a limit mechanism provided on the inner side of the placement frame.

[0007] A polishing mechanism includes a polishing belt connected to one side of the top of the operating table and a first electric push rod fixedly connected to the surface of the placement frame. One end of the first electric push rod passes through the inner side of the placement frame and is fixedly connected to a cylinder. A round rod is slidably connected to the inner wall of the cylinder. One end of the round rod passes through the cylinder and is fixedly connected to a push plate. A spring is fixedly connected between the other end of the round rod and the inner wall of the cylinder.

[0008] Furthermore, the grinding mechanism also includes a limiting plate fixedly connected to the top of the operating table, with the upper end of one side of the limiting plate in contact with the surface of the grinding belt.

[0009] Furthermore, a through groove is provided at the top of the operating table, and the through groove is located below the grinding belt.

[0010] Furthermore, three brushes are fixedly connected to one side of the inner wall of the channel, and the surface of the brushes is in contact with the surface of the polishing belt.

[0011] Furthermore, a receiving frame is fixedly connected to one side of the bottom of the operating table. The receiving frame is connected to the through groove, and a sealing plate is provided at the bottom of the receiving frame.

[0012] Furthermore, a marker is fixedly connected to the surface of the placement frame, and a magnifying glass is fixedly connected to one side of the top of the marker.

[0013] Furthermore, a contact pad, which is a rubber component, is fixedly connected to the other side of the push plate.

[0014] Furthermore, the vertical cross-section of the limiting plate is a right triangle, and the horizontal height of the top of the limiting plate is the same as the horizontal height of the bottom wall inside the placement frame. Beneficial effects

[0015] The aforementioned grinding mechanism utilizes a first electric push rod to push the cut of the rod to fit against the surface of the grinding belt. Under the combined action of the cylinder, rod, and spring, when the grinding belt grinds a relatively flat area of ​​the cut, the spring automatically bends. This allows the rod to self-adjust during the grinding process, preventing damage to the cut when there are large uneven areas. This ensures the grinding effect of the rod's cut. Furthermore, the limiting plate facilitates better control of the rod's movement distance during the pushing process, improving the practicality of the device.

[0016] By setting multiple brushes to clean the area being polished by the polishing belt in sequence, the polishing debris is prevented from remaining on the polishing belt, ensuring that the polishing belt remains flat during the polishing process. This ensures the fit between the polishing belt and the cut during the polishing process, thereby guaranteeing the polishing effect on the cut of the rod. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A cutting edge grinding device for cutting metal frames includes an operating table 100, a placement frame 200 rotatably connected to the top of the operating table 100, and a limit mechanism 300 provided on the inner side of the placement frame 200.

[0028] In this embodiment of the utility model, the limiting mechanism 300 includes two second electric push rods that are respectively fixedly connected to both sides of the placement frame 200. One end of the second electric push rod passes through the inner side of the placement frame 200 and is fixedly connected to a movable plate. When limiting the rod, the rod is placed inside the placement frame 200 and the limiting mechanism 300 is driven to run so that the two movable plates in the limiting mechanism 300 are in contact with the surface of the rod.

[0029] The top of the operating table 100 is provided with scale lines. The angle of the rod can be adjusted by using the scale lines through the placement frame 200. A fixing block is fixedly connected to one side of the placement frame 200. A bolt is threadedly connected to the inner wall of the fixing block. A fixing plate is fixedly connected to the bottom end of the bolt. After rotating the placement frame 200 to the required angle, the fixing plate can be pushed against the top of the operating table 100 by rotating the bolt to limit the placement frame 200.

[0030] The grinding mechanism 400 includes a grinding belt 410 that is driven to one side of the top of the operating table 100 and a first electric push rod 420 that is fixedly connected to the surface of the placement frame 200. One end of the first electric push rod 420 passes through the inner side of the placement frame 200 and is fixedly connected to a cylinder 430. A round rod 440 is slidably connected to the inner wall of the cylinder 430. One end of the round rod 440 passes through the cylinder 430 and is fixedly connected to a push plate 460. A spring 450 is fixedly connected between the other end of the round rod 440 and the inner wall of the cylinder 430.

[0031] In this embodiment of the utility model, two circular rollers are rotatably connected to one side of the top of the operating table 100. The grinding belt 410 is driven between the two circular rollers. A motor is fixedly connected to the bottom of the operating table 100. The output shaft of the motor passes through the operating table 100 and is fixedly connected to the bottom of the circular rollers. When it is necessary to use the grinding belt 410 to grind the rod, the motor can be started by the controller to drive the grinding belt 410.

[0032] After placing and fixing the rod in the placement frame 200, the angle of the rod is adjusted by rotating the placement frame 200 so that the cut of the rod is parallel to the grinding belt 410. After rotating to the required angle, the placement frame 200 is fixed. At this time, the controller starts the first electric push rod 420 to push the cylinder 430, spring 450, rod 440 and push plate 460 to move synchronously, so that push plate 460 pushes the rod to move synchronously. When the cut of the rod contacts the surface of the grinding belt 410, the larger uneven areas at the cut will squeeze the grinding belt 410 and make the surface of the grinding belt 410... When deformation occurs, the grinding belt 410 drives the grinding belt to grind the cut of the rod. When grinding larger uneven areas, the grinding belt 410 will squeeze the rod, causing the rod to push the push plate 460 in the opposite direction. The push plate 460 drives the round rod 440 to move into the cylinder 430, and the spring 450 is compressed. As the larger uneven areas are gradually ground, the grinding belt 410 will gradually release the pressure on the rod, causing the spring 450 to return to its original position. The push plate 460 will then drive the rod to gradually return to its original position, so that the cut of the rod is completely in contact with the surface of the grinding belt 410, thus ensuring the grinding effect on the cut.

[0033] In some embodiments, as Figure 4As shown, in a preferred embodiment of the present invention, the grinding mechanism 400 further includes a limiting plate 470 fixedly connected to the top of the operating table 100, and the upper end of one side of the limiting plate 470 is in contact with the surface of the grinding belt 410.

[0034] In this embodiment of the invention, during the process of the first electric push rod 420 pushing the rod to move, when the cut of the rod and one side of the limiting plate 470 are on the same vertical plane, the cut of the rod contacts the surface of the grinding belt 410. At this time, it is convenient for the first electric push rod 420 to complete the position movement of the rod. This facilitates better control of the moving distance of the rod during the pushing process, thereby ensuring the grinding effect on the cut of the rod.

[0035] In some embodiments, as Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the top of the operating table 100 is provided with a through groove 480, which is located below the grinding belt 410.

[0036] In this embodiment of the invention, the width of the through groove 480 is greater than the width of the grinding belt 410. Some of the debris generated during the grinding process of the rod cut will fall through the through groove 480, which is beneficial for better accumulation of debris.

[0037] In some embodiments, as Figure 5 As shown, in a preferred embodiment of the present invention, three brushes 482 are fixedly connected to one side of the inner wall of the through groove 480, and the surface of the brushes 482 is in contact with the surface of the polishing belt 410.

[0038] In this embodiment of the utility model, after the grinding belt 410 grinds the cut and continues to drive, the grinding position of the grinding belt 410 will come into contact with the brush 482, and during the transmission process, multiple brushes 482 will clean the surface of the grinding belt 410 in turn, and the debris cleaned by the brushes 482 will fall off through the through groove 480.

[0039] Multiple brushes 482 sequentially clean the area being polished by the polishing belt 410, preventing polishing debris from remaining on the polishing belt 410 and ensuring that the polishing belt 410 remains flat during the polishing process.

[0040] In some embodiments, as Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, a receiving frame 481 is fixedly connected to one side of the bottom end of the operating table 100. The receiving frame 481 is connected to the through groove 480, and a sealing plate 483 is provided at the bottom end of the receiving frame 481.

[0041] In this embodiment of the utility model, the sealing plate 483 can be connected to the receiving frame 481 by bolts. The debris falling from the through groove 480 will enter the receiving frame 481, thereby better collecting the debris. When it is necessary to clean the debris in the receiving frame 481, the sealing plate 483 at the bottom of the receiving frame 481 can be opened, making cleaning more convenient.

[0042] In some embodiments, as Figure 2 As shown, in a preferred embodiment of the present invention, a marker 210 is fixedly connected to the surface of the placement frame 200, and a magnifying glass 220 is fixedly connected to one side of the top of the marker 210.

[0043] In this embodiment of the utility model, the marker 210 is located on the side away from the opening of the placement frame 200. Therefore, when the rod is placed inside the placement frame 200, the staff can better observe the rotation angle of the placement frame 200 by rotating the placement frame 200 to adjust the angle of the rod. The magnifying glass 220 makes it easier for the staff to observe.

[0044] In some embodiments, as Figure 3 As shown, in a preferred embodiment of the present invention, a contact pad 461 is fixedly connected to the other side of the push plate 460, and the contact pad 461 is a rubber component.

[0045] In this embodiment of the invention, when the push plate 460 pushes the rod to move, the surface of the contact pad 461 contacts the surface of the rod, increasing the friction between the push plate 460 and the surface of the rod, while also protecting the contact position.

[0046] In some embodiments, as Figure 4 As shown, in a preferred embodiment of the present invention, the vertical cross-section of the limiting plate 470 is a right triangle, and the horizontal height of the top of the limiting plate 470 is the same as the horizontal height of the bottom wall of the placement frame 200.

[0047] In this embodiment of the utility model, when the rod is inside the placement frame 200 and the rod is pushed to move, the limiting plate 470 will not affect the movement of the rod.

[0048] It should be noted that the electric linear actuators and motors mentioned above are devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric linear actuators and motors can be powered by built-in power supplies or mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
