DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Embodiment one:

[0028] As Figures 1 to 6 shown, the utility model embodiment one provides a kind of scrap collection structure, especially suitable for the collection and discharge of scrap in laser cutting operation.The structure mainly includes cutting platform 1 and slag discharge component, and can be selected and matched lifting slag plate 9 and baffle 10 and the like auxiliary components, to realize efficient, convenient, sufficient scrap collection.

[0029] As Figure 1 shown, cutting platform 1 is equipped with cutting pad 2, it is made of multiple longitudinal clamping plate 3 and multiple sawtooth plate 4.Cutting platform 1 is clamped in the clamping groove on cutting platform 1 along the length direction of cutting platform 1 by longitudinal clamping plate 3, and sawtooth plate 4 is perpendicular to the intersection with longitudinal clamping plate 3 by clamping, forms stable grid structure.Workpiece to be cut can be placed on sawtooth plate 4.Slag collecting cavity 5 is located in the inside of cutting platform 1, is specially designed for collecting these scrap, and slag collecting cavity 5 is provided with slag discharge port 8 at one end.In the longitudinal clamping plate 3 and between sawtooth plate 4, intentionally leave fall slag gap, so that the scrap generated in cutting process can smoothly fall into the slag collecting cavity 5 below.

[0030] The design of the slag discharge assembly fully considers the effective discharge of the waste scraps. The slag discharge assembly comprises a slag pushing plate 6 and a side pushing plate 7, both of which have the freedom of moving along the length direction of the longitudinal clamping plate 3 and the sawtooth plate 4. As shown in Figure 3 the driving mechanism, two parallel first lead screws 14 are rotatably installed on both sides of the slag collecting cavity 5, and the two ends of the slag pushing plate 6 are threadedly connected with the two first lead screws 14. By rotating the first lead screw 14, the movement control of the slag pushing plate 6 in the length direction of the longitudinal clamping plate 3 can be realized. In order to facilitate the driving, a transmission rod 15 is also rotatably installed on the slag collecting cavity 5, and the two ends of the transmission rod 15 are respectively connected with the two first lead screws 14 through two bevel gear sets, so that the effect that one first motor 16 can simultaneously drive the synchronous rotation of the two first lead screws 14 is realized, and then the movement of the slag pushing plate 6 is more stable.

[0031] For the driving of the side pushing plate 7, a second lead screw 17 is rotatably installed on the end of the slag collecting cavity 5 close to the slag discharge port 8, the second lead screw 17 is perpendicular to the first lead screw 14, and the side pushing plate 7 is threadedly connected with the second lead screw 17. By rotating the second lead screw 17, the transverse movement control of the side pushing plate 7 can be realized. Similarly, the second lead screw 17 is also connected with a second motor 18 to realize the electric driving.

[0032] In use, the cut waste scraps fall into the slag collecting cavity 5 from the slag falling gap. When the waste scraps are collected more, the first motor 16 can be started, the first motor 16 drives the first lead screw 14 to rotate, and then drives the slag pushing plate 6 to move in the slag collecting cavity 5. Combined Figure 3 and Figure 6 It can be seen that when the slag pushing plate 6 moves from the end far away from the slag discharge port 8 to the slag discharge port 8, the waste scraps in the slag collecting cavity 5 can be pushed to the slag discharge port 8. When the slag pushing plate 6 contacts the side pushing plate 7, the first motor 16 stops, the second motor 18 starts, the second motor 18 drives the second lead screw 17 to rotate, so that the side pushing plate 7 discharges the gathered waste scraps from the slag discharge port 8.

[0033] Example two:

[0034] On the basis of example one, in order to improve the efficiency of waste scrap discharge and avoid the accumulation of waste scraps at the end of the slag pushing plate 6 far away from the slag discharge port 8, the utility model designs a slag lifting plate 9 and a blocking plate 10. As shown in Figure 4 and Figure 5 the slag lifting plate 9 is fixed on the side of the slag pushing plate 6 far away from the slag discharge port 8, one end of the slag lifting plate 9 is buckled on the top of the slag pushing plate 6, and the other end is abutted on the bottom surface of the slag collecting cavity 5. When the slag pushing plate 6 moves away from the direction of the slag discharge port 8, the slag lifting plate 9 can push the waste scraps in the slag collecting cavity 5 away from the direction of the slag discharge port 8, and lift the blocking plate 10 when it contacts.

[0035] The inner wall of the slag collecting cavity 5 far from the slag discharge port 8 is provided with a sliding groove 11 on both sides, and the baffle 10 is slidingly installed in the sliding groove 11 to provide a guide for the stable lifting of the baffle 10. The bottom of the baffle 10 is further provided with a guide slope 12 matched with the slag lifting plate 9. When the slag lifting plate 9 abuts against the baffle 10 and the slag lifting plate 9 continues to move, the baffle 10 is lifted up. At this time, the baffle 10 will be attached to the surface of the slag lifting plate 9, scrape the waste slag between the slag lifting plate 9 and the baffle 10, and push the waste slag to the side of the slag pushing plate 6 close to the slag discharge port 8, so as to complete the cleaning of the waste scraps on the side of the slag pushing plate 6 far from the slag discharge port 8.

[0036] In addition, the inner wall of the slag collecting cavity 5 on the side of the baffle 10 far from the slag lifting plate 9 is further provided with a giving slot 13. This design is used to provide the necessary space for the movement of the slag lifting plate 9 when lifting the baffle 10, so as to prevent structural interference or damage caused by insufficient space.

[0038] The embodiment provides a laser cutting machine, which comprises the waste scrap collecting structure in the embodiment one to the embodiment two, further comprises a gantry slidingly installed on the cutting platform 1 and a laser generator arranged on the gantry. The laser generator generates a laser beam, and the workpiece on the lower cutting base plate 2 is cut through the cutting nozzle. Obviously, those skilled in the art can make various modifications and changes to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and changes of the utility model belong to the scope of the utility model claim and its equivalent technology, the utility model also intends to include these modifications and changes.
