Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a feeding mechanism for a laser cutting machine. Background Technology

[0002] A laser cutting machine is an industrial device that uses a high-power-density laser beam to precisely cut materials. It is widely used in the processing of materials such as metals, plastics, wood, and ceramics. A high-energy laser beam is generated by a laser, then transmitted through a mirror or optical fiber, and focused into an extremely small spot (typically 0.1–0.3 mm in diameter) by a lens. The laser beam irradiates the surface of the material, causing it to melt, vaporize, or ablate instantly. An auxiliary gas (such as oxygen or nitrogen) blows away the molten slag, forming a cutting kerf.

[0003] When laser cutting machines continuously cut metal sheets, existing laser cutting machines generally lack a material unloading mechanism. After cutting one side, manual unloading is required before continuing cutting. However, the cut sheet material is at a high temperature, and directly handling it poses a risk of injury. Furthermore, manually unloading material at the laser cutting head location is also dangerous. Therefore, this invention proposes a material unloading mechanism for laser cutting machines to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a feeding mechanism for a laser cutting machine. A flipping mechanism is provided on the support and connected to a hollow feeding box. The clamping mechanism on the hollow feeding box can cooperate with the positioning mechanism of the laser cutting machine to fix both ends of the plate. After cutting, the small plate automatically slides into the inside of the hollow feeding box by flipping the hollow feeding box. The cut small plate can be temporarily stored and cooled in the hollow feeding box, and it is not easy to be burned when manually taking out the small plate from the feeding port.

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

[0006] A feeding mechanism for a laser cutting machine includes a support frame positioned above the cutting table of the laser cutting machine. Electromagnetic tracks are provided on both side walls of the cutting table, and the support frame is slidably connected to the electromagnetic tracks. A hollow feeding box is located above the cutting table on one side of the support frame. A flipping mechanism is located inside the lower part of the support frame. The flipping mechanism includes a flipping shaft and a connecting seat. The flipping shaft is rotatably located inside the lower part of the support frame and is driven by a flipping motor. The connecting seat is located on the flipping shaft. One end of the hollow feeding box is connected to the connecting seat. An opening is located at the end of the hollow feeding box away from the flipping mechanism. A clamping mechanism is located inside the opening. The clamping mechanism is symmetrically arranged with the positioning mechanism of the laser cutting machine. A feeding port is located on the front of the hollow feeding box near the flipping mechanism. A limiting mechanism is located inside the hollow feeding box.

[0007] A further improvement is that the connecting seat has an L-shaped structure, a fixing bolt is provided on the connecting seat, and a fixing hole is provided on one side wall of the hollow material box, and the fixing bolt is connected to the fixing hole.

[0008] A further improvement is that the clamping mechanism includes a clamping cylinder and a clamping plate. The top of the hollowed-out feeding box at the opening position is provided with a clamping cylinder, and the inside of the opening is provided with a clamping plate. The output end of the clamping cylinder is connected to the clamping plate.

[0009] A further improvement is that: the hollow material box at the material outlet position has a groove inside, and a discharge plate is slidably arranged in the groove, with the top of the discharge plate flush with the bottom of the hollow material box.

[0010] A further improvement is that one end of the discharge plate extends outward from the discharge port, and a groove is provided on the extended end of the discharge plate.

[0011] Further improvements are made in that: the limiting mechanism includes an adjusting cylinder, a mounting plate and a guide roller; the front and rear side walls of the hollow feeding box are provided with adjusting cylinders; the interior of the hollow feeding box is symmetrically provided with mounting plates; the output end of the adjusting cylinder is connected to the mounting plate; the mounting plate is provided with a mounting groove; a guide roller is rotatably provided in the mounting groove; multiple sets of guide rollers are provided, and one side of each set of guide rollers extends out of the mounting groove.

[0012] The beneficial effects of this utility model are as follows: This utility model sets up a support above the cutting table of the laser cutting machine and slides the support to the electromagnetic track, so that the support can move. The support is equipped with a flipping mechanism connected to the hollow material box. The clamping mechanism on the hollow material box can cooperate with the positioning mechanism of the laser cutting machine to fix both ends of the plate. After cutting, the small plate automatically slides into the hollow material box by flipping the hollow material box. The cut small plate can be temporarily stored and cooled in the hollow material box. When the small plate is manually removed from the feeding port, it is not easy to be burned. Moreover, the feeding port is far away from the laser cutting head of the laser cutting machine, which ensures high safety. Attached Figure Description

Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] Example 1

[0020] according to Figure 1-4 As shown, this embodiment proposes a feeding mechanism for a laser cutting machine, including a support 1. The support 1 is disposed above the cutting table 2 of the laser cutting machine. Electromagnetic tracks 3 are provided on both side walls of the cutting table 2. The support 1 is slidably connected to the electromagnetic tracks 3. A hollow feeding box 4 is provided above the cutting table 2 on one side of the support 1. A flipping mechanism is provided inside the lower part of the support 1. The flipping mechanism includes a flipping shaft 5 and a connecting seat 6. The flipping shaft 5 is rotatably disposed inside the lower part of the support 1. The flipping shaft 5 is driven by a flipping motor. The connecting seat 6 is provided on the flipping shaft 5. One end of the hollow feeding box 4 is connected to the connecting seat 6. An opening 7 is provided at the end of the hollow feeding box 4 away from the flipping mechanism. A pressing mechanism is provided inside the opening 7. The pressing mechanism is symmetrically arranged with the positioning mechanism 18 of the laser cutting machine. A feeding port 8 is provided on the front of the hollow feeding box 4 near the flipping mechanism. A limiting mechanism is provided inside the hollow feeding box 4.

[0021] When the unloading mechanism of the laser cutting machine of this utility model is working, the plate being cut by the laser cutting machine is fixed at one end by the positioning mechanism 18, and the other end of the plate is inserted into the opening 7 and fixed by the clamping mechanism. The laser cutting head of the laser cutting machine is started to cut, and the plate fixed by the clamping mechanism is the small plate cut off. During unloading, the bracket 1 is moved away from the positioning mechanism 18 on the electromagnetic track 3, and then the flipping mechanism is started to make the hollow unloading box 4 flip and tilt as a whole. Then the clamping mechanism is released to fix the small plate, and the cut small plate automatically slides into the unloading port 8 on one side inside the hollow unloading box 4. Then the hollow unloading box 4 is controlled to reset, and the bracket 1 moves towards the positioning mechanism 18 on the electromagnetic track 3, so that one end of the plate held by the positioning mechanism 18 enters the opening 7 again. Then the other end of the plate is fixed by the clamping mechanism again, waiting for the next cutting. After the next cutting is completed, the small board cut from the previous cutting can be manually removed from the feeding port 8 (at this time, the small board has been temporarily stored and cooled in the hollow feeding box 4. In order to further improve the cooling effect of the cut board, this utility model can also introduce a cold air pipe into the top of the hollow feeding box 4 to blow air into it for cooling. The hollow feeding box 4 of this utility model can effectively facilitate heat dissipation and cooling).

[0022] The connecting seat 6 has an L-shaped structure and is equipped with a fixing bolt 9. A fixing hole 10 is provided on one side wall of the hollow material box 4, and the fixing bolt 9 connects to the fixing hole 10. This utility model allows the hollow material box 4 to be disassembled from the connecting seat 6 by using the fixing bolt 9, thus facilitating the replacement of the hollow material box 4.

[0023] The clamping mechanism includes a clamping cylinder 11 and a clamping plate 12. The clamping cylinder 11 is located on the top of the hollow material box 4 at the opening 7, and the clamping plate 12 is located inside the opening 7. The output end of the clamping cylinder 11 is connected to the clamping plate 12. When the clamping mechanism is working, the clamping cylinder 11 extends to drive the clamping plate 12 to clamp the material.

[0024] The hollowed-out feeding box 4 at the feeding port 8 has a groove inside, and a discharge plate 13 slides within the groove. The top of the discharge plate 13 is flush with the bottom of the hollowed-out feeding box 4. This design facilitates the smooth entry of small cutting boards into the top of the discharge plate 13, making it easy to slide and pull out the discharge plate 13 for subsequent discharge. One end of the discharge plate 13 extends outward from the feeding port 8, and a pull groove 14 is provided on the extended end of the discharge plate 13. When removing the small cutting board from the feeding port 8, the small board located on the discharge plate 13 can be moved out of the hollowed-out feeding box 4 by pulling the discharge plate 13.

[0025] This invention features a support 1 mounted above the cutting table 2 of a laser cutting machine, which is slidably connected to an electromagnetic track 3, allowing the support 1 to move. The support 1 is equipped with a flipping mechanism connected to a hollow material box 4. The clamping mechanism on the hollow material box 4 can cooperate with the positioning mechanism 18 of the laser cutting machine to fix both ends of the sheet metal. After cutting, the small sheet metal is automatically slid into the hollow material box 4 by flipping the hollow material box 4. The cut small sheet metal can be temporarily stored and cooled in the hollow material box 4. When the small sheet metal is manually removed from the feeding port 8, it is less likely to be burned. Moreover, the feeding port 8 is far away from the laser cutting head of the laser cutting machine, ensuring high safety.

[0026] Example 2

[0027] according to Figure 1-4 As shown, this embodiment proposes a feeding mechanism for a laser cutting machine, including a support 1. The support 1 is disposed above the cutting table 2 of the laser cutting machine. Electromagnetic tracks 3 are provided on both side walls of the cutting table 2. The support 1 is slidably connected to the electromagnetic tracks 3. A hollow feeding box 4 is provided above the cutting table 2 on one side of the support 1. A flipping mechanism is provided inside the lower part of the support 1. The flipping mechanism includes a flipping shaft 5 and a connecting seat 6. The flipping shaft 5 is rotatably disposed inside the lower part of the support 1. The flipping shaft 5 is driven by a flipping motor. The connecting seat 6 is provided on the flipping shaft 5. One end of the hollow feeding box 4 is connected to the connecting seat 6. An opening 7 is provided at the end of the hollow feeding box 4 away from the flipping mechanism. A pressing mechanism is provided inside the opening 7. The pressing mechanism is symmetrically arranged with the positioning mechanism 18 of the laser cutting machine. A feeding port 8 is provided on the front of the hollow feeding box 4 near the flipping mechanism. A limiting mechanism is provided inside the hollow feeding box 4.

[0028] The limiting mechanism includes adjusting cylinders 15, mounting plates 16, and guide rollers 17. Adjusting cylinders 15 are provided on both the front and rear side walls of the hollow material box 4. Mounting plates 16 are symmetrically arranged inside the hollow material box 4. The output end of each adjusting cylinder 15 is connected to the mounting plate 16. Mounting plates 16 have mounting grooves, and guide rollers 17 are rotatably mounted within these grooves. Multiple sets of guide rollers 17 are provided, with one side of each set extending out of the mounting groove. By setting the limiting mechanism, the two sides of the internal cavity of the hollow material box 4 can be limited, allowing the limiting channel between the two sets of mounting plates 16 to restrict the deflection of the cut small sheet material within it, facilitating the smooth sliding of the cut small sheet material to the designated position.
