Description

Technical Field

[0001] The present application relates to the technical field of laser cutting machines, and in particular to a feeding structure of a metal plate laser cutting machine. Background Art

[0002] A laser cutting machine primarily consists of a laser generator, an optical system, a focusing head, and a control system. During operation, the laser generator produces a high-energy laser beam, which is guided and adjusted by optical components such as collimators and reflectors to accurately focus on the workpiece. The lens in the focusing head focuses the laser beam into a small, high-intensity spot. By adjusting the focal length and focal diameter, the laser beam forms a high-power density spot on the workpiece surface, rapidly heating the localized area of ​​the material to its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal, forming a slit and achieving cutting.

[0003] The feeding process of a metal plate laser cutting machine is a critical step, directly affecting the efficiency and quality of cutting. Traditional metal plate laser cutting machines use a conveyor belt to feed the material. This feeding method requires manual placement of metal plates onto the conveyor belt one by one, and the spacing between adjacent metal plates is inconsistent, making subsequent laser cutting inconvenient. Therefore, to address the above issues, this application provides a feeding structure for a metal plate laser cutting machine. Utility Model Content

A plurality of vertically arranged metal plate bodies are placed above the support plates, and a passing groove is formed between the two support plates. A second conveyor belt is provided below the support plate, and a push plate is fixedly connected to the outer wall of the second conveyor belt. The height of the push plate is adjustable, and the push plate cooperates with the passing groove to push the metal plate body.

[0006] Preferably, a plurality of rollers are provided on the upper wall of the supporting plate, and the setting direction of the rollers is consistent with the transmission direction of the second conveyor belt.

[0007] Preferably, limiting plates are provided on opposite sides of the support, the limiting plates are "T"-shaped, and fixed plates are fixedly provided above the support.

[0010] Preferably, the side walls of the vertical plates are fixedly connected with fixed blocks, the side walls of the blocking plates are fixedly connected with connecting blocks, and the fixed blocks are connected to the connecting blocks via electric push rods.

[0011] Preferably, the laser cutting machine body and the support are directly provided with a first conveyor belt, and the upper surface of the first conveyor belt is flush with the upper surface of the supporting plate.

[0012] In summary, this application has the following beneficial technical effects:

[0013] Multiple metal plate bodies are stacked and placed on top of the supporting plate, and the screws are rotated separately to move the limit plates to limit the left and right movement of the metal plates. The electric push rod is started to adjust the height of the blocking plate so that the distance between it and the supporting plate is greater than the thickness of one metal plate and less than the thickness of two metal plates. The height of the push plate is then adjusted so that its highest point is higher than the upper wall of the supporting plate and lower than the upper wall of the lowest metal plate. The second conveyor belt is started to move the push plate and push the lowest metal plate to the first conveyor belt for subsequent cutting. The distance between adjacent metal plates is the same. Compared with the traditional method, there is no need to place the metal plates one by one, only multiple ones need to be stacked, which saves manpower, and the distance between adjacent metal plates is the same, which is convenient for subsequent cutting.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] Example 1

[0021] Reference Figure 1-4 A feeding structure for a metal sheet laser cutting machine includes a laser cutting machine body 1. Two supports 3 are provided on one side of the laser cutting machine body 1. Support plates 7 are fixedly connected to opposite sides of the supports 3. Supports 3 and the support plates 7 on the corresponding sides are provided below the supports 3 to ensure that they are stably placed on the ground. A first conveyor belt 2 is directly provided between the laser cutting machine body 1 and the supports 3. The first conveyor belt 2 is driven by an external structure, which is a well-known and mature technology and will not be described in detail here. The upper surface of the first conveyor belt 2 is flush with the upper surface of the support plates 7, facilitating the transportation of metal sheets.

[0022] A plurality of vertically arranged metal plate bodies 14 are placed above the support plate 7. A through slot 12 is formed between the two support plates 7. A second conveyor belt 4 is provided below the support plate 7. The second conveyor belt 4 is driven by an external structure, which is a well-known mature technology and will not be described here. A push plate 5 is fixedly connected to the outer wall of the second conveyor belt 4. The height of the push plate 5 can be adjusted by a socket or a threaded connection. Figure 4 , which is an existing mature technology.

[0023] A plurality of rollers 6 are provided on the upper wall of the supporting plate 7 , and the setting direction of the rollers 6 is consistent with the transmission direction of the second conveyor belt 4 . When the metal plate body 14 is placed on the supporting plate 7 , the setting of the rollers 6 facilitates its movement.

[0024] Limit plates 13 are provided on opposite sides of the support 3. These limit plates 13 are T-shaped and limit the left and right movement of the metal plate body 14. If there is a concern that the metal plate may slip from the rear, a limit plate fixedly connected to the limit plates 13 can be installed behind the metal plate. Fixed plates 8 are fixedly provided above the support 3. Slide rods 11 are provided through the fixed plates 8 and slidably connected to them. The slide rods 11 are fixedly connected to the limit plates 13. Screws 9 are provided through the fixed plates 8 and threadedly connected to them. The screws 9 are rotatably connected to the limit plates 13. A turntable 10 is fixedly connected to the ends of the screws 9 away from the limit plates 13.

[0025] The ends of the supports 3 near the laser cutting machine body 1 are fixedly connected to risers 15, with blocking plates 17 disposed between the risers 15. Slide slots 16 are disposed on opposite sides of the risers 15, with both ends of the blocking plates 17 slidingly connected to the blocking plates 17 via the slide slots 16. Fixed blocks 20 are fixedly connected to the side walls of the risers 15, and connecting blocks 18 are fixedly connected to the side walls of the blocking plates 17. The fixed blocks 20 are connected to the connecting blocks 18 via electric push rods 19.

[0026] During actual use, multiple metal plate bodies 14 are first stacked and placed on top of the supporting plate 7, and the turntable 10 is rotated to rotate the screw 9, so that the limit plate 13 moves until it fits the left and right walls of the metal plate body 14, and the left and right movement of the metal plate body 14 is limited. The electric push rod 19 is started to slide the blocking plate 17, so as to adjust the height of the blocking plate 17 so that the distance between its lower wall and the supporting plate 7 is greater than the thickness of one metal plate and less than the thickness of two metal plates, which facilitates the smooth feeding of one metal plate and the remaining metal plates are blocked by the blocking plate 17; then adjust the height of the pushing plate 5 so that its highest point is higher than the upper wall of the supporting plate 7 and lower than the upper wall of the lowest metal plate, which facilitates pushing the lowest metal plate and does not contact the remaining metal plates. Start the second conveyor belt 4 to move the push plate 5, pushing the bottom metal plate to the first conveyor belt 2 for subsequent cutting. The rotation speed of the first conveyor belt 2 and the second conveyor belt 4 is stable, so the distance between adjacent metal plates is roughly the same. This device does not need to place the metal plates one by one, but only needs to stack multiple plates, which saves manpower, and the distance between adjacent metal plates is the same, which is convenient for subsequent cutting.
