Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a blanking line worktable mechanism for laser cutting slender plates. Background Technology

[0002] With the widespread application of pipe tower components in the photovoltaic industry, power pipe towers, construction and other fields, the processing requirements for slender plates used to manufacture pipe towers are also diverse and varied. For example, due to different usage environments, the height of pipe towers varies, with common single tower heights ranging from a few meters to more than ten meters. Therefore, laser blanking lines have become the preferred equipment for processing such slender plates due to their high cutting flexibility, high material utilization rate and no need for mold costs.

[0003] The automatic feeding mechanism of a coil laser cutting line typically uses a chain to drive a toothed plate, which is then moved in a circular motion by a motor to complete the cyclic feeding. Because slender sheets vary in length when cutting, the cutting kerf can easily align with the toothed plate support table when cutting in a direction parallel to the toothed plate. This can easily result in the tooth tips cutting off the plate, causing unevenness on the support surface and affecting cutting quality. Furthermore, the coil laser cutting line consists of uncoiling, leveling, laser cutting, unloading, and stacking equipment. Following the standard "one-line" layout of a laser cutting worktable, a buffer zone is often set up to prevent sheet movement during unloading from affecting the sheet positioning in the cutting area. In the material handling area and the cutting area, at least one workpiece position should be reserved. However, this method increases the equipment footprint too much for slender plates. If the plates are directly cut, the current toothed plate conveyor table is an integral structure with a single power source. After cutting, some material will still remain on the automatic feeding mechanism. That is, the material before the cutting slit needs to be conveyed to the sorting area, and the material after the cutting slit needs to be stationary for cutting. If the conveyor in the sorting area feeds directly, it is easy to cause scratches on the plates that remain on the automatic feeding mechanism. How to process slender plates using a blanking line has become a production problem that enterprises with limited factory length and high workpiece surface requirements must consider.

[0004] When a laser cutting machine is working, laser cutting of workpieces will generate some spatter. This spatter will adhere to the toothed plate support frame of the laser cutting machine and form iron slag. If it is not cleaned in time, it will gradually increase, causing the toothed plate support frame to become uneven or even scratch the workpiece. In addition, due to the interval arrangement of the toothed plate support frame, if the plate is severely deformed or sags at the entrance, the plate can easily enter the feeding mechanism, causing the conveying to be interrupted and affecting production. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a blanking line worktable mechanism for laser cutting slender plates, which can effectively save the cutting line area and reduce scratches on the plate. It can also effectively prevent unevenness of the toothed plate support frame from scratching the workpiece and provide sufficient support and guidance for the plate.

[0006] To achieve the above objectives, this utility model discloses a blanking line worktable mechanism for laser cutting slender plates, comprising a laser cutting body, a cutting machine beam support frame, an inlet mounting plate, an outlet mounting plate, an automatic feeding mechanism, a drive sprocket shaft, a driven sprocket shaft, a toothed plate support plate, a material head cutting support table, a bearing seat, a cutting roller, a conveying roller, a slag cleaning brush roller, a wire brush roller, a wire brush roller shaft, a wire brush sprocket, a driven shaft sprocket, a tensioning wheel, an inlet guide device, a transition table, and a limiting wheel. The laser cutting body further includes a cutting machine beam support frame, on which the automatic feeding mechanism is installed. One end of the cutting machine beam support frame is fixedly mounted with an inlet guide device via the inlet mounting plate, and the other end is fixedly mounted with a material head cutting support table via the outlet mounting plate. The automatic feeding mechanism and the material head cutting support table form a toothed plate-supported cutting area and a roller-supported cutting area. A slag cleaning brush roller is located below the inlet guide device near the automatic feeding mechanism.

[0007] In addition, the blanking line worktable mechanism for laser cutting slender plates proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the automatic feeding mechanism includes a drive sprocket shaft, a driven sprocket shaft, and a toothed plate support plate. The drive sprocket shaft and the driven sprocket shaft are respectively installed on the crossbeam support frame of the cutting machine. The drive sprocket shaft drives the multiple toothed plate support plates installed on the chain to roll back and forth.

[0009] As a further improvement of this utility model, the material head cutting support table includes bearing seats, cutting rollers and conveying rollers. Four or five pairs of bearing seats are installed side by side on the outlet mounting plate. Two or more sets of cutting rollers and two sets of conveying rollers are respectively installed on the four or five pairs of bearing seats through rotating shafts.

[0010] As a further improvement of this utility model, the slag cleaning brush roller includes a wire brush roller, a wire brush roller shaft, a wire brush sprocket, a driven shaft sprocket, and a tensioning wheel. The driven shaft sprocket is provided at the outer end of the driven shaft shaft. The driven shaft sprocket is connected to the wire brush sprocket, and the wire brush sprocket drives the wire brush roller through the wire brush roller shaft.

[0011] As a further improvement of this utility model, the entrance guide device includes a transition platform and limiting wheels. The transition platform is fixedly installed on the entrance mounting plate, and limiting wheels are installed on the outer sides of the transition platform respectively.

[0012] As a further improvement of this utility model, the crossbeam support frame of the cutting machine is a crossbeam mounting base for the laser cutting head. By setting two or more crossbeams, the cutting efficiency of short and thin plates can be significantly improved.

[0013] By employing the above-described solution, this utility model possesses at least the following advantages: Compared to conventional cutting lines, by shortening the length of the automatic feeding mechanism and adding a roller-supported cutting area at the rear of the toothed plate support cutting area, the problem of scratches caused by the plate material remaining on the toothed plate support conveyor chain after cutting slender plates is solved. It also effectively reduces transverse cutting damage to the toothed plate during coil cutting, improves the uniformity of the support frame in the toothed plate support cutting area, and ensures cutting quality. Furthermore, by setting up a slag-cleaning brush roller, the splashed cutting slag is cleaned promptly, extending the lifespan of the toothed plate support frame and improving cutting stability. Finally, by setting up an inlet guide device, the plate material is fed smoothly, preventing severe deformation or sagging of the plate from causing it to enter the gaps in the toothed plate support frame, thus avoiding conveying interruptions and disrupting orderly production.

[0021] The following description, in conjunction with the accompanying drawings, describes a blanking line worktable mechanism for laser cutting slender plates according to this utility model.

[0022] In Embodiment 1 of this application, as Figure 1 and Figure 2 As shown, this invention (hereinafter referred to as "the invention") is a blanking line worktable mechanism for laser cutting slender plates, comprising a laser cutting body 1, a cutting machine crossbeam support frame 11, an inlet mounting plate 12, an outlet mounting plate 13, an automatic feeding mechanism 14, a drive sprocket shaft 141, a driven sprocket shaft 142, a toothed plate support plate 143, a material head cutting support table 2, a bearing seat 21, a cutting roller 22, a conveying roller 23, a slag cleaning brush roller 3, a wire brush roller 31, a wire brush roller shaft 32, a wire brush sprocket 33, a driven shaft sprocket 34, a tensioning wheel 35, and an inlet guide device 4. The laser cutting body 1 includes a transition table 41, a limiting wheel 42, and a cutting machine crossbeam support frame 11. An automatic feeding mechanism 14 is installed on the cutting machine crossbeam support frame 11. An inlet guide device 4 is fixedly installed at one end of the cutting machine crossbeam support frame 11 via an inlet mounting plate 12, and a material head cutting support table 2 is fixedly installed at the other end of the cutting machine crossbeam support frame 11 via an outlet mounting plate 13. The automatic feeding mechanism 14 and the material head cutting support table 2 form a toothed plate supporting cutting area and a roller supporting cutting area. A slag cleaning brush roller 3 is located below the inlet guide device 4 near the automatic feeding mechanism 14. The automatic feeding mechanism 14 includes a drive sprocket shaft 141, a driven sprocket shaft 142, and a toothed plate support plate 143. The drive sprocket shaft 141 and the driven sprocket shaft 142 are respectively installed on the cutting machine crossbeam support frame 11. The drive sprocket shaft 141 drives multiple toothed plate support plates 143 installed on the chain to roll back and forth.

[0023] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figures 2 to 5 As shown, the material head cutting support platform 2 includes bearing seats 21, cutting rollers 22, and conveying rollers 23. Four or five pairs of bearing seats 21 are installed side by side on the outlet mounting plate 13. Two or more sets of cutting rollers 22 and two sets of conveying rollers 23 are respectively installed on the four or five pairs of bearing seats 21 through rotating shafts. The slag cleaning brush roller 3 includes a wire brush roller 31, a wire brush roller shaft 32, a wire brush sprocket 33, a driven shaft sprocket 34, and a tensioning wheel 35. The driven shaft sprocket 34 is provided at the outer end of the driven shaft shaft 142. The driven shaft sprocket 34 is connected to the wire brush sprocket 33 through a drive mechanism. The wire brush sprocket 33 drives the wire brush roller 31 through the wire brush roller shaft 32. The inlet guiding device 4 includes a transition platform 41 and limiting wheels 42. The transition platform 41 is fixedly installed on the inlet mounting plate 12, and limiting wheels 42 are respectively installed on the outer sides of the transition platform 41.

[0024] To further optimize the working efficiency of this application, the cutting machine crossbeam support frame 11 is a crossbeam mounting base for the laser cutting head. By setting two or more crossbeams, the cutting efficiency of short and thin plates can be significantly improved.

[0025] When this utility model is used, its specific operation is as follows:

[0026] In actual production, the rolled material is continuously fed into the automatic feeding mechanism 14 from the inlet guide device 4. The inlet guide device 4 extends from the inlet to directly above the driven sprocket shaft 142, first resting on the transition table 41 and guided by the limit wheel 42. Then, the motor of the automatic feeding mechanism 14 drives the drive sprocket shaft 141 to rotate, causing the chain on it to roll on the drive sprocket shaft 141 and the driven sprocket shaft 142. Multiple toothed support plates 143 mounted side by side on the chain form the cutting platform of the automatic feeding mechanism 14. During feeding, the entire cutting platform rolls forward, allowing the slender sheet material to enter the working range of the laser cutting head. Then, the cutting platform stops working, and the crossbeam mounting seat, carrying the laser cutting head, begins working. After the cutting is completed, the cutting platform continues to roll before the automatic feeding mechanism 14 finishes cutting. The automatic feeding mechanism 14 drives the slender plate to move. At the same time, the driven sprocket shaft 142 drives the driven shaft sprocket 34 to rotate. The driven shaft sprocket 345 drives the wire brush sprocket 33 and the wire brush roller shaft 32 through gears or chains, driving the wire brush roller 31 to clean the toothed plate on the toothed plate support plate 143 of the automatic feeding mechanism 14 that passes over its surface, sweeping off the welding slag and residual material. When the plate passes through the material head cutting support table 2, the cutting roller 22 and the conveying roller 23 work at the same time. The cutting roller 22 serves as the cutting support roller, and the conveying roller 23 serves as the connection support to the conveyor belt of the subsequent process, realizing the support of the plate that has been cut on the plate when it is sent to the subsequent process, preventing the plate from bending. The cutting roller 22 and the conveying roller 23 are both unpowered and rely on the conveyor of the next process to drag away the slender plate. Since the slender plate is completely cut off at the position of the cutting roller 22, the slender plate after the cutting roller 22 cuts the seam can be removed from the cutting machine without affecting the continued cutting of the steel plate on the toothed plate of the automatic feeding mechanism 14. In this way, continuous cutting of slender plates can be achieved, and the toothed plates on the toothed plate support plate 143 can be prevented from scratching the plate when the conveyor belt of the next process drags away the plate.

[0027] In summary, the blanking line workbench mechanism for laser cutting slender plates according to this embodiment of the invention, by shortening the length of the automatic feeding mechanism 14 and adding a material head cutting support table 2 at the rear section of the toothed plate support cutting area, solves the problem of scratching the plate material stuck on the toothed plate support plate 143 during conveying after the slender plate is cut. It also effectively reduces the cutting damage to the toothed plate during transverse cutting of the coiled material, improves the uniformity of the support frame in the toothed plate support cutting area, and ensures cutting quality. By setting a slag-cleaning brush roller 3, the splashed cutting slag is cleaned up in a timely manner, extending the life of the toothed plate support frame and improving cutting stability. By setting an inlet guide device 4, the plate material is fed smoothly, preventing the plate material from entering the gap of the toothed plate support frame due to severe deformation or sagging, which would cause conveying interruption and affect the orderly production process.

[0028] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
