Description

Technical Field

[0001] This utility model belongs to the field of tinplate processing technology, and in particular relates to a magnetic feeding structure. Background Technology

[0002] Tinplate is a metallic material made by plating a layer of tin onto the surface of iron or steel, primarily to prevent the underlying iron or steel from rusting and corroding. Tinplate requires both transverse and longitudinal cutting during processing to obtain the desired dimensions.

[0003] Currently, the transverse and longitudinal cutting of tinplate (hereinafter referred to as "workpiece") are separate. There is a transitional conveyor platform between the longitudinal and transverse cutting stations, with the discharge end of the longitudinal cutting equipment higher than the transitional conveyor platform. At the longitudinal cutting station, after the longitudinal cutting equipment completes the longitudinal cutting of the workpiece, it pushes the workpiece horizontally from the discharge end. Then, the workpiece falls onto the transitional conveyor platform in a parabolic trajectory, and the transitional conveyor platform then transports the workpiece to the transverse cutting station. However, in actual observation, it has been found that during the process of the workpiece moving from the discharge end of the longitudinal cutting equipment to the transitional conveyor platform, the workpiece is prone to slipping off the transitional conveyor platform. At the same time, the workpiece is at an inclined angle when contacting the transitional conveyor platform, which also poses a risk of being scratched. Once the workpiece is scratched, the tin plating layer is damaged, which will affect its performance. Therefore, the existing feeding method needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a magnetic feeding structure. This magnetic feeding structure can decelerate the workpiece horizontally after it is pushed out by the slitting equipment, and then push the workpiece vertically down after the workpiece and the transition conveyor platform are aligned in the vertical direction, thereby improving the stability of the workpiece transfer from the slitting equipment to the transition conveyor platform.

[0005] In view of this, the present invention provides a magnetic feeding structure, including: a frame;

[0006] Multiple wheels are distributed horizontally at intervals. Each wheel is rotatably connected to the frame. The outer surface of each wheel extends vertically out of the frame and contacts the workpiece. The wheels are made of plastic.

[0007] A magnetic ring is placed inside the wheel body and is coaxially distributed with the wheel body. The magnetic ring can attract workpieces.

[0008] The pusher is mounted on the frame and can push the workpiece away from the wheel in a vertical direction.

[0009] In this technical solution, a magnetic feeding structure is installed between the slitting equipment and the transition conveying platform. The magnetic feeding structure is close to the discharge end of the slitting equipment in the horizontal direction, and the bottom surface of the wheel is at the same height as or slightly higher than the discharge end of the slitting equipment. The transition conveying platform is located below the magnetic feeding structure. When the slitting equipment pushes the workpiece horizontally, the workpiece passes under the wheel at a certain horizontal speed due to inertia. During this process, the magnetic ring in the wheel will attract the workpiece, causing the workpiece to move horizontally along the wheel. The magnetic attraction of the magnetic ring can decelerate the workpiece in the horizontal direction. Then, the workpiece will continue to move a distance in the horizontal direction and continuously contact other wheels. Finally, the horizontal speed of the workpiece is zero and it is attracted by multiple magnetic rings. At this time, the pusher pushes the workpiece downward in the vertical direction, so that the weight of the workpiece is greater than the attraction of the magnetic ring. At this time, the workpiece will fall vertically onto the transition conveying platform.

[0010] In the above technical solution, the pusher component further includes:

[0011] The push plate is located on one side of the wheel body along the axial direction and can move relative to the frame.

[0012] A cylinder can drive a push plate to move in the vertical direction.

[0013] In the above technical solution, the cylinder is further mounted vertically on the frame, and the output rod of the cylinder is vertically downward and connected to the push plate.

[0014] In the above technical solution, the pusher further includes a swing frame, the middle part of which is rotatably connected to the frame, the lower end of which is rotatably connected to the push plate, and the cylinder is horizontally mounted on the frame, with the output rod of the cylinder rotatably connected to the upper end of the swing frame.

[0015] In the above technical solution, furthermore, the push plate covers all wheels in the horizontal direction.

[0016] In the above technical solution, furthermore, auxiliary frames are provided on both sides of the frame in the horizontal direction of the push plate. The upper end of the auxiliary frame is rotatably connected to the frame, the lower end of the auxiliary frame is rotatably connected to the push plate, and an elastic element is provided between the auxiliary frame and the frame.

[0017] In the above technical solution, furthermore, multiple wheel bodies are divided into multiple groups along the axial direction, and multiple groups of wheel bodies can contact the workpiece.

[0018] The beneficial effects of this utility model are:

[0019] 1. Through the cooperation of the frame, multiple wheels, multiple magnetic rings, and pusher components, the workpiece pushed horizontally out by the slitting equipment can be decelerated horizontally by the cooperation of the magnetic rings and wheels. During this process, the workpiece moves horizontally under the guidance of the wheels and will not come into contact with other objects. Finally, the workpiece is attracted by the magnetic rings above the transition conveyor platform. At this time, the pusher components push the workpiece vertically away from the magnetic rings, and then the workpiece will fall onto the transition conveyor platform under the action of gravity. This can avoid the surface of the workpiece being scratched, ensure the performance of the workpiece, and improve production efficiency.

[0020] 2. By designing the pusher component as a combination of a pusher plate and a cylinder, the cylinder only needs to complete a linear reciprocating motion to drive the pusher plate to reciprocate in the vertical direction, thus completing the pushing and resetting of the workpiece. The action is simple and the pushing is fast.

[0021] 3. By designing the push plate to cover all wheels in the horizontal direction, the push plate can protect all wheels and magnetic rings, preventing external objects from contacting and damaging the wheels or magnetic rings, thus extending the service life of the magnetic feeding structure.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] The magnetic feeding structure 100 of this utility model is installed between the slitting equipment 300 and the transition conveying platform 400. Please refer to [link / reference]. Figure 1The magnetic feeding structure 100 is positioned horizontally near the discharge end of the slitting device 300 in the X direction. The bottom surface of the wheel 2 is at the same height as or slightly higher than the discharge end of the slitting device 300. The transition conveyor platform 400 is located below the magnetic feeding structure 100. The width of the transition conveyor platform 400 in the X direction can be smaller than the width of the magnetic feeding structure 100 in the X direction. Generally, the width of the transition conveyor platform 400 in the X direction only needs to be slightly wider than the workpiece 200. However, since the workpiece 200 needs to move horizontally a certain distance on the magnetic feeding structure 200, the width of the magnetic feeding structure 100 in the X direction needs to be greater than the width of the workpiece 200 in the X direction. The position of the transition conveyor platform 400 in the X direction is adjustable. When installing the magnetic feeding structure 100, the final stopping position of the workpiece 200 in the X direction needs to be tested first, and then the transition conveyor platform 400 can be adjusted to be below that position.

[0035] The structure and adjustment method of the transition conveying platform 400, as well as the structure of the slitting device 300, are well known to those skilled in the art and are not improvements of this utility model. Therefore, they will not be described in detail. In the following embodiments, only the content of the magnetic feeding structure 100 will be described.

[0036] Example 1

[0037] like Figures 2-5 As shown, this embodiment provides a magnetic feeding structure, including: a frame 1, multiple wheels 2, a magnetic ring 3, and a pusher component;

[0038] Please see Figure 2 Multiple wheels 2 are distributed at intervals along the horizontal direction X. Each wheel 2 is rotatably connected to the frame 1. The outer surface of each wheel 2 extends out of the frame 1 in the vertical direction Y and contacts the workpiece 200. The workpiece 200 can contact multiple wheels 2 at the same time. When the workpiece 200 contacts the wheel 2, it will not contact the frame 1. The wheels 2 are made of plastic. In this embodiment, the wheels 2 can be made of nylon.

[0039] Please see Figure 5 The magnetic ring 3 is set in the wheel body 2. The magnetic ring 3 is coaxially distributed with the wheel body 2. The magnetic ring 3 can attract the workpiece 200 through the wheel body 2, so that the workpiece 200 can stick to the outer surface of the wheel body 2. When the workpiece 200 is close to the wheel body 2, the magnetic attraction force of the magnetic ring 3 on the workpiece 200 is slightly greater than the weight of the workpiece 200.

[0040] In this embodiment, a magnetic ring 3 can be provided in each wheel body 2, or a magnetic ring 3 can be provided at intervals of several wheel bodies 2. However, it must be ensured that when the workpiece 200 is in contact with multiple wheel bodies 2, the corresponding magnetic ring 3 can attract the workpiece 200.

[0041] The pusher is mounted on the frame 1. The pusher can push the workpiece 200 away from the wheel 2 in the vertical direction Y. When the workpiece 200 is away from the wheel 2, the magnetic attraction force of the magnetic ring 3 on the workpiece 200 gradually decreases. Finally, the gravity of the workpiece 200 can make the workpiece 200 fall up and down in the vertical direction Y. In the current actual test, the pusher can push the workpiece 200 down by 30mm to make the workpiece 200 get rid of the magnetic attraction of the magnetic ring 3.

[0042] In this embodiment, after the slitting device 300 pushes the workpiece 200 horizontally, the workpiece 200 passes under the wheel 2 at a certain horizontal speed under the action of inertia. During this process, the magnetic ring 3 in the wheel 2 will attract the workpiece 200, causing the workpiece 200 to move horizontally along the wheel 2. The magnetic attraction of the magnetic ring 3 can decelerate the workpiece 200 in the horizontal direction X. Then the workpiece 200 will continue to move a distance in the horizontal direction X and continuously contact other wheels 2. Finally, the horizontal speed of the workpiece 200 is zero and it is attracted by multiple magnetic rings 3. At this time, the pusher pushes the workpiece 200 downward in the vertical direction Y, so that the weight of the workpiece 200 is greater than the attraction of the magnetic ring 3. At this time, the workpiece 200 will fall onto the transition conveyor platform 400 in the vertical direction Y.

[0043] Example 2

[0044] Based on Embodiment 1, this embodiment also discloses a structure for the pusher component;

[0045] In this embodiment, the pusher component includes: a pusher plate 4 and a cylinder 5;

[0046] Please see Figure 4 The push plate 4 is located on one side of the wheel body 2 along the axial direction, and the push plate 4 can move relative to the frame 1;

[0047] Cylinder 5 can drive push plate 4 to move in the vertical Y direction;

[0048] In this embodiment, specifically, the cylinder 5 is vertically mounted on the frame 1, and the output rod of the cylinder 5 is vertically downward and connected to the push plate 4. In the initial state, the bottom surface of the push plate 4 is higher than the contact surface between the workpiece 200 and the wheel 2 in the vertical direction Y. The push plate 4 will not affect the horizontal deceleration of the workpiece 200 under the cooperation of the wheel 2 and the magnetic ring 3. When the speed of the workpiece 200 in the horizontal direction X is zero, the cylinder 5 drives the push plate 4 to move downward, so that the workpiece 200 can fall freely. Then the cylinder 5 drives the push plate 4 to move upward and reset.

[0049] Example 3

[0050] This embodiment also discloses a structure of a pusher component. In this embodiment, the pusher component also includes a push plate 4 and a cylinder 5. The difference from embodiment 2 is that in this embodiment, the cylinder 5 is horizontally arranged on the frame 1, and the pusher component also includes a swing frame 6.

[0051] For details, please refer to Figure 4 The swing frame 6 is L-shaped or Z-shaped. The middle part of the swing frame 6 is rotatably connected to the frame 1 through the rotating shaft 601. The lower end of the swing frame 6 is rotatably connected to the push plate 4. The output rod of the cylinder 5 is rotatably connected to the upper end of the swing frame 6.

[0052] by Figure 4 Taking the orientation sequence as an example, when the speed of the workpiece 200 in the horizontal direction X is zero, the cylinder 5 drives the upper end of the swing frame 6 to swing away from the cylinder 5. During this process, the lower end of the swing frame 6 swings downward and moves the push plate 4 downward, so that the workpiece 200 can fall freely. Then the cylinder 5 drives the upper end of the swing frame 6 to swing closer to the cylinder 5. During this process, the lower end of the swing frame 6 swings upward and moves the push plate 4 upward, so as to reset the push plate 4.

[0053] Example 4

[0054] Based on Embodiment 2 or Embodiment 3, this embodiment further optimizes the structure of the push plate 4;

[0055] Please see Figure 2 In this embodiment, the push plate 4 covers all the wheels 2 in the horizontal direction X. In this way, the push plate 4 can protect all the wheels 2 and the magnetic ring 3, prevent external objects from contacting and damaging the wheels 2 or the magnetic ring 3, and extend the service life of the magnetic feeding structure 100.

[0056] Example 5

[0057] Based on Example 4, this embodiment further optimizes the magnetic feeding structure 100;

[0058] Please see Figure 2 In this embodiment, auxiliary frames 7 are provided on both sides of the frame 1 and on the horizontal X direction of the push plate 4. The upper end of the auxiliary frame 7 is rotatably connected to the frame 1 through the rotating shaft 601, and the lower end of the auxiliary frame 7 is rotatably connected to the push plate 4. An elastic element is provided between the auxiliary frame 7 and the frame 1.

[0059] The elastic components can be selected from commercially available elastic structures such as springs, torsion springs, and rubber.

[0060] Because the push plate 4 is quite long, it is difficult to ensure the stable movement of the push plate 4 by connecting it to a single point via the cylinder 5 or the swing frame 6. Therefore, auxiliary frames 7 are set near both ends of the push plate 4. During the process of the cylinder 5 driving the push plate 4 to move downward, the two sets of auxiliary frames 7 can swing downward with the push plate 4. During this process, the elastic element is stretched and accumulates elastic force. During the process of the push plate 4 resetting, the elastic force of the elastic element can assist the push plate 4 in resetting.

[0061] Example 6

[0062] Based on Example 1, this embodiment further expands the usage of the magnetic feeding structure 100;

[0063] In this embodiment, multiple wheel bodies 2 are divided into multiple groups along the axial direction, and all groups of wheel bodies 2 can contact the workpiece 200.

[0064] As a preferred option, please refer to Figure 6 Multiple sets of wheels 2 are all set on the same frame 1. At this time, a set of magnetic feeding structure 100 can stably transfer the workpiece 200.

[0065] As a preferred option, please refer to Figure 7 Multiple sets of magnetic feeding structures 100 are distributed at intervals along the axial direction of the wheel body 2 to transfer the workpiece 200 together. In this case, each set of magnetic feeding structures 100 can only have one set of wheel body 2 along the axial direction of the wheel body 2.

[0066] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
