Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation equipment, and more specifically, to an automated laser cutting machine for color steel coils. Background Art

[0002] A color steel coil is a composite material, also known as a color coated steel plate. It is a product made by continuously passing strip steel through chemical conversion coatings such as surface degreasing and phosphating on a production line, and then applying an organic coating and baking. When cutting a color steel coil, laser cutting of the color steel coil has become the preferred solution to replace traditional mechanical cutting in modern industry due to its advantages of high precision, non-contact processing, and coating protection. Chinese Publication No.: CN222660462U discloses a laser cutting machine. On the machine base, there is a processing platform with a certain length and two parallel tracks located on the left and right sides of the processing platform. Material tensioning mechanisms are respectively provided at both ends of the processing platform in the length direction. Two cutting modules are installed and moved along the same tracks, and the two cutting modules move and process independently in two areas. The cutting module includes a crossbeam straddling between the two tracks and a cutting laser head installed on the crossbeam and capable of moving along the crossbeam. Both ends of the crossbeam are respectively connected to the tracks through sliding carriages, and a driving motor is correspondingly arranged for each sliding carriage. The driving motor drives the sliding carriage to reciprocate along the track. This patent realizes simultaneous processing of two cutting modules, improving processing efficiency. The material tensioning mechanism helps to stably flatten the material on the processing platform, improving processing quality and qualification rate. The double-drive form of the crossbeam improves speed and smoothness, thereby helping to improve production efficiency. Although the above patent uses two cutting modules for simultaneous processing to improve processing efficiency, and uses the double-drive form of the crossbeam to improve speed and smoothness, thereby helping to improve production efficiency, when considering cutting color steel plates of specific sizes, it is necessary to ensure the synchronization of their transportation and cutting. Moreover, when cutting the corners of color steel plates, it is inconvenient to cut at specific angles.

[0025] As Figures 7 - 8As shown in the figure, a first slider 4352 is slidably connected to the top of the guard plate 12. A top of the first slider 4352 is fixedly connected to an arch member 435.

The convex column 4341 is slidably connected within the second arch hole 4351. The adjustment assembly 4 further includes a first sliding frame 44. A third rack 421 is slidably connected to a bottom of the first sliding frame 44. At two top sides of the first sliding frame 44, second sliding frames 441 are fixedly connected.

At two sides of one end of the limiting plate 461, second sliders 462 are fixedly connected. The second sliders 462 are slidably connected within a strip-shaped hole 242. The second sliders 462 are fixedly connected to a bottom of a second rack 243.

[0026] It can be seen from this that when automatic laser cutting of the color steel coil is required, as Figures 2 - 6 shown, after the coiled color steel coil is rolled flat and conveyed onto a conveyor belt 1 in the previous process, when the color steel coil reaches the position of the adjustment assembly 4, it will drive a first rack 11 to move along the conveyor belt 1 together under the rotation and conveyance of the conveyor belt 1. Since the first rack 11 meshes with a second gear 43, when the first rack 11 moves to the position of the second gear 43, it will drive the second gear 43 to rotate. Then, during the rotation of the second gear 43, it will drive a rotating rod 431, a convex turntable 432, and a concave turntable 433 to rotate together. When a convex part of the convex turntable 432 rotates to the position of the groove 451 of the sliding plate 45 and is blocked by the groove 451, the sliding plate 45 will slide a certain distance in the rotation direction of the second gear 43. During the sliding of the sliding plate 45, it will drive the fixing strip 46 to slide inwards a small distance together. At this time, the two fixing strips 46 fix the color steel coil inside them; Then, driven by the electric slide rail 21, the telescopic frame 23 drives the platform 24 and the transmission chamber 25 to slide towards one side. At this time, driven by the motor 31, the turntable 311 and the first gear 32 rotate together. Since the position of the second rack 243 is restricted by the fixed bar 46, during the process of the electric slide rail 21 driving the platform 24 and the transmission chamber 25 to move, the relative position of the second rack 243 with respect to the first gear 32 changes, and the position of the first gear 32 gradually approaches the second rack 243 on one side until the first gear 32 meshes with the second rack 243. Then, during the rotation of the first gear 32, it will drive the laser cutting head 33 to slide from one end to the other end of the first arched hole 241, and under the contraction of the telescopic frame 23, cut the color steel coil; It should be noted that when the first rack 11 at one end drives the second gear 43 to rotate, the second gear 43 will simultaneously drive the third rack 421 to move to one side. When the first rack 11 finishes driving the second gear 43 to rotate, under the elastic influence of the spring 423, the third rack 421 rebounds towards the initial central position. At this time, the third rack 421 will simultaneously drive the second gear 43 to rotate back, which will cause the second gear 43 to rotate in the opposite direction back to the initial angle. Then, the rotation of the second gear 43 will pull the fixed bar 46 back to its original position, stop fixing the color steel coil, and enable the color steel coil to continue to be conveyed and undergo the next cutting; In addition, during the rotation of the second gear 43, it will also drive the rotating rod 431 to rotate. When the rotating rod 431 rotates, it will slide through the protruding column 4341 in the second arched hole 4351 and drive the arched member 435 to slide left and right. When the arched member 435 and the first slider 4352 slide to the position of the touch sensor 121 on the guard plate 12 and contact the touch sensor 121, the entire conveyor belt 1 stops conveying. After stopping the conveying, the color steel coil is cut by the movement of the laser cutting head 33, and after the cutting is completed, the color steel coil continues to be conveyed. Since the interval distances of the multiple sections of the first rack 11 are the same, the cutting widths of the color steel coil are also the same; In addition, when cutting the corner position of the color steel coil that needs to be cut, as Figure 7 shown, during the process of the electric slide rail 21 driving the platform 24 and the transmission chamber 25 to move left and right, the laser cutting head 33 will move left and right together. At this time, the motor 31, the turntable 311, and the first gear 32 all move together under the left and right sliding of the sliding table. At this time, the fixed ring 331 will slide on the outer wall of the limiting plate 461. When the fixed ring 331 slides to the end position of the limiting plate 461, driven by the motor 31, the laser cutting head 33 will move towards the corner position of the color steel coil. After reaching the corner position and completing the cutting, the motor 31 reverses and returns to its original position and then performs a horizontal overall cutting.
