Description

Technical Field

[0001] This utility model relates to a conveying mechanism and a sheet metal laser cutting machine, belonging to the field of sheet metal processing technology. Background Technology

[0002] Laser cutting technology utilizes a high-energy laser beam to irradiate the surface of a workpiece, bringing it to its melting or boiling point to achieve the cutting requirement. Simultaneously, high-pressure gas, coaxial with the laser beam, blows away the molten or vaporized metal. Laser cutting technology is widely used in sheet metal processing; the cutting of pipes, cylindrical iron bars, and sheet metal is primarily accomplished using laser cutting machines.

[0003] When sheet metal parts are cut using a laser cutting machine, they need to be transported to the laser cutting machine via a conveyor mechanism before being cut. To improve conveying efficiency, sheet metal parts are usually placed directly on the conveyor mechanism and transported. However, non-standard placement of sheet metal parts can affect the cutting effect. To ensure standardized placement and transport of sheet metal parts, manual adjustment is required. Manual processing not only increases processing costs but also reduces conveying efficiency and affects sheet metal processing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a conveying mechanism and a sheet metal laser cutting machine equipped with the conveying mechanism. The conveying mechanism can correct and align directly placed sheet metal parts to ensure the standardization of subsequent cutting.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A conveying mechanism and a sheet metal laser cutting machine include a conveyor belt and a correction mechanism disposed on the conveyor belt. The correction mechanism includes a support frame disposed on the conveyor belt, electric telescopic rods disposed on both sides inside the support frame, and a correction device connected through the electric telescopic rods. The correction device includes a stop block and a plurality of drive rollers disposed inside the stop block. A pressure block is connected to the upper end face of the support frame through a second electric telescopic rod, and a conveying roller is connected to the pressure block through a drive motor.

[0007] Furthermore, the support frame includes support plates disposed on both sides of the conveyor belt and a top plate disposed above the space between the two support plates, and the electric telescopic rod is fixedly connected to the support plates.

[0008] Furthermore, both ends of the stop are provided with sliding plates, and the two sliding plates near the opening of the conveyor belt have an outward V-shaped structure. The lower end faces of the stop and the sliding plates are rotatably connected with steel balls.

[0009] Furthermore, a groove is provided on the side of the stop block near the support plate, and a compression spring is provided inside the groove. The telescopic end of the electric telescopic rod is located in the groove and connected to the compression spring.

[0010] Furthermore, a cavity is formed on the side of the stop block away from the support plate, and several drive rollers are rotatably connected to the cavity. The inner side of the drive rollers protrudes into the inner side of the stop block. A sprocket is provided above each of the drive rollers, and the sprockets are linked by a chain. A drive motor is provided on the upper end face of the stop block, and the drive motor is connected to one of the drive rollers.

[0011] Furthermore, a rotating groove is provided on the lower end face of the pressure block, the conveying roller is rotatably connected to the rotating groove, one end of the conveying roller extends through to the outside of the pressure block and is connected to a first gear, the output end of the drive motor is connected to a second gear that meshes with the first gear, and the lower end face of the conveying roller protrudes to the lower end face of the pressure block.

[0012] Furthermore, a support leg is provided below the conveyor belt, and the support leg is positioned close to the starting end of the conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When conveying sheet metal parts using the conveying mechanism of this application, two outward-facing sliding plates are first used to initially correct the conveyed sheet metal parts. When the guide device limits and corrects the sheet metal parts, the compression spring not only prevents the sheet metal parts from getting stuck, but also achieves the correction effect, ensuring angle correction during sheet metal conveying. After the sheet metal parts are initially corrected by the outward-facing sliding plates, they are conveyed to the position of the drive rollers. The drive motor drives one of the drive rollers to rotate, and the sprockets and chains achieve synchronous rotation of multiple drive rollers, thereby assisting in the conveying of the corrected sheet metal parts. This allows the directly placed sheet metal parts to be corrected and aligned, ensuring the standard of subsequent cutting. There is no need for manual adjustment of the sheet metal parts' position, which greatly improves the conveying efficiency and helps to improve the sheet metal processing efficiency.

Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, the conveying mechanism provided in this embodiment includes a conveyor belt 1 and a correction mechanism disposed on the conveyor belt 1;

[0024] The correction mechanism includes a support frame 2 installed on the conveyor belt 1, electric telescopic rods 3 installed on both sides of the support frame 2, and a correction device 4 connected through the electric telescopic rods 3. The support frame 2 includes support plates 11 installed on both sides of the conveyor belt 1 and a top plate 12 installed above the two support plates 11. The electric telescopic rods 3 are fixedly connected to the support plates 11.

[0025] The guide device 4 includes a stop block 5 and several drive rollers 6 disposed inside the stop block 5. Both ends of the stop block 5 are provided with slide plates 13. The two slide plates near the opening of the conveyor belt 1 have an outward V-shaped structure, which can ensure that the conveyed sheet metal parts are initially corrected. The lower end surfaces of the stop block 5 and the slide plates 13 are rotatably connected with steel balls 14. The rolling steel balls can reduce the friction when the stop block 5 and the slide plates 13 contact the conveyor belt 1.

[0026] Furthermore, a groove 15 is provided on the side of the stop block 5 near the support plate 11, and a compression spring 16 is provided inside the groove 15. The telescopic end of the electric telescopic rod 3 is located in the groove 15 and connected to the compression spring 16. When the correction device 4 performs limit correction on the sheet metal part, the setting of the compression spring 16 not only prevents the sheet metal part from being stuck, but also achieves the correction effect, realizing the angle correction when the sheet metal part is transported.

[0027] Furthermore, a cavity is provided on the side of the stop block 5 away from the support plate 11, and several drive rollers 6 are rotatably connected to the cavity. The inner side of the drive rollers 6 protrudes from the inner side of the stop block 5. A sprocket 17 is provided above each of the drive rollers 6, and the sprockets 17 are linked by a chain 18. A drive motor 19 is provided on the upper end face of the stop block 5, and the drive motor 19 is connected to one of the drive rollers 6. The sheet metal part is initially corrected by the outward V-shaped sliding plate 13 and is then conveyed to the position of the drive roller 6. Then, the drive motor 19 drives one of the drive rollers 6 to rotate. The arrangement of the sprockets 17 and the chain 18 can realize the synchronous rotation of multiple drive rollers 6, thereby realizing the auxiliary conveying of the corrected sheet metal part.

[0028] The upper end face of the support frame 2 is connected to a pressure block 8 via a second electric telescopic rod 7, and a conveying roller 10 is connected to the pressure block 8 via a drive motor 9.

[0029] Furthermore, a rotating groove is provided on the lower end face of the pressure block 8, and the conveying roller 10 is rotatably connected to the rotating groove. One end of the conveying roller 10 extends through to the outside of the pressure block 8 and is connected to a first gear 20. The output end of the drive motor 9 is connected to a second gear 21 that meshes with the first gear 20. The lower end face of the conveying roller 10 protrudes to the lower end face of the pressure block 8. When the sheet metal part is corrected and is located directly below the support frame 2, the drive motor 9 drives the second gear 21 to rotate, which in turn drives the first gear 20 to rotate, thereby driving the conveying roller 10 to rotate. This not only achieves the pressing and positioning of the sheet metal part, but also does not affect the conveying.

[0030] This embodiment also provides a sheet metal laser cutting machine, which includes the conveying mechanism and support leg 22. The support leg 22 is located below the conveyor belt 1 and is positioned close to the starting end of the conveyor belt 1, so that the conveying and discharging end of the conveyor belt 1 can be placed directly below the laser cutting machine.

[0031] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
