Description

Technical Field

[0001] This utility model relates to the field of laser machine technology, and in particular to a waste cleaning device for laser machines. Background Technology

[0002] Laser cutting processes generate a large amount of waste, which would be a significant waste if discarded directly. Therefore, a waste cleaning device for laser machines (publication number CN221754994U) addresses this issue. It involves activating a cylinder to cut the material with the laser head. After cutting, an electric telescopic rod is activated until a brush can contact the waste. Simultaneously, a drive motor is activated, causing a threaded rod to rotate within a mounting slot. As the threaded rod rotates, a connecting frame moves with a moving block within the mounting slot, allowing the brush to clean the waste remaining on the crossbar. The waste then falls through a funnel into a collection box. A nozzle, powered by a water pump, sprays water from the tank into the collection box through the main and branch pipes, cooling the waste. Once a certain amount of waste has accumulated in the collection box, the operator moves the box using a handle to clean and recycle the waste.

[0003] However, the gaps between the crossbars are the only channel for waste to fall. Oversized waste will get stuck in the gaps of the wavy crossbars. The brush can only clean the surface of the crossbars and cannot push out or break up the large pieces of waste stuck in the gaps. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a waste cleaning device for laser machines.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figures 1-4 As shown, a waste cleaning device for laser cutting machines includes a laser cutting machine tool 1. The machine tool 1 has a frame-shaped surface with an inner frame 2 that fits within it. One long side of the inner frame 2 is hinged to the inner wall of the machine tool 1, and several equally spaced serrated plates 3 are fixedly installed inside the inner frame 2. During the cutting process, the inner frame 2 is raised to a horizontal position, and the steel plate to be cut can be placed on the several serrated plates 3 of the inner frame 2. Each serrated plate 3 has a U-shaped insert 4 inserted into its bottom edge. The top edge of the insert 4 is flat, and several insert 4 are raised and lowered synchronously. The waste generated during the cutting process will get stuck at the serrations on the surface of the serrated plate 3. At this time, the insert 4 is raised to the top edge and is flush with the top edge of the serrated plate 3, which can replace the serrated plate 3 to support the waste. At this time, the waste is placed on the flat surface, and then the inner frame 2 is lowered so that the waste can slide off the upper surface of the inner frame 2 naturally using the flat surface of the top edge of the insert 4. A traction bar 13 is inserted into the bottom surface of the machine tool 1 near the swing edge of the inner frame 2. Several hydraulic rods 12 for driving the traction bar 13 to rise and fall are fixedly installed on the bottom surface of the machine tool 1. A guide rail 16 is fixedly installed on the bottom surface of the machine tool 1, which is vertically arranged and passes through the top edge of the traction bar 13 near the wire rope 14. The traction bar 13 rises and falls longitudinally, and wire ropes 14 are installed at both ends of the upper surface of the traction bar 13. A rope groove 15 is opened on the upper surface of the machine tool 1 above the wire ropes 14, and the release end of the wire rope 14 passes through it. The rope groove 15 at the upper position is connected to the swing edge of the inner frame 2. In actual use, the hydraulic rod 12 is used to extend and retract to lower or raise the traction bar 13. When the traction bar 13 rises with the assistance of the guide rail 16, it releases the downward pull on the wire rope 14. At this time, the inner frame 2 can swing down naturally under the action of gravity. When the traction bar 13 falls, it can pull the wire rope 14, and then, with the rope groove 15 restricting the swaying of the wire rope 14, it pulls the inner frame 2 back up to a horizontal state. In addition, as Figure 2 As shown, the inner wall of the machine tool 1 extends downward into a plate shape at the position of the wire rope 14. The plate-shaped part shields the wire rope 14 to prevent the scrap material that slides down when the inner frame 2 tilts downward from impacting the wire rope 14.

[0020] Arc-shaped bars 11 are fixedly installed on two adjacent sides of the bottom surface of the machine tool 1 where the traction bar 13 is located. The arc-shaped bars 11 are set close to the swing side of the inner frame 2 and are coaxially distributed with the swing fulcrum of the inner frame 2. Both sides of the swing side of the inner frame 2 extend outward and the two extensions are respectively set close to the two arc-shaped bars 11. The arc-shaped bars 11 pass through the extension of the inner frame 2. The arc-shaped bars 11 can ensure that the inner frame 2 is stable during the up and down swing.

[0021] A connecting frame 5 is provided on the bottom surface of the inner frame 2. The connecting frame 5 surrounds the bottom surface of the inner frame 2 and is fixedly connected to the two sides of the bottom surface of the insert shell 4. Therefore, by driving the connecting frame 5 to rise and fall, all insert shells 4 inside the inner frame 2 can be raised and lowered synchronously. The connecting frame 5 extends upward from two adjacent sides of the swing side of the inner frame 2 and passes through the gap between the inner frame 2 and the machine tool 1. Two symmetrically arranged inclined slots 10 are opened on the surface of the extension of the connecting frame 5. A slider 7 is inserted into the upper surface of the inner frame 2 near each inclined slot 10. The side of the slider 7 protrudes outward and slides in connection with the inner wall of the corresponding inclined slot 10. A bidirectional screw 6 is rotatably connected to each extension of the connecting frame 5 on the upper surface of the inner frame 2. By rotating the bidirectional screw 6, a threaded connection can be achieved, and the two sliders 7 arranged on the same side can move relative to or towards each other. Figure 3 When the two sliders 7 move closer to each other, the connecting frame 5 can be lowered by the insertion of the sliders 7 into the inner wall of the inclined groove 10. When the two sliders 7 move away from each other, the connecting frame 5 can drive the car body to rise. To achieve simultaneous rotation of the two bidirectional lead screws 6 on both sides, the two ends of the bidirectional lead screw 6 are threadedly connected to two sliders 7 on the same side of the inner frame 2, and a coaxially distributed single gear shaft 8 is fixedly installed at the end of the bidirectional lead screw 6 facing the hinge side of the inner frame 2. A double gear shaft 9 is rotatably connected to the upper surface of the inner frame 2 at the hinge side. The gears at both ends of the double gear shaft 9 are respectively meshed with the gear ends of the two single gear shafts 8. The gears at both ends of the single gear shaft 8 and the double gear shaft 9 are bevel gears. Therefore, in actual use, it is only necessary to install a motor on the inner frame 2 to drive one of the bidirectional lead screws 6 to rotate, which will realize the rotation of the single gear shaft 8 on the bidirectional lead screw 6. Under the meshing connection and transmission action of the double gear shaft 9, the other single gear shaft 8 will drive the corresponding bidirectional lead screw 6 to rotate.

[0022] The method of using this utility model is as follows: Before laser cutting, the operator must first activate the hydraulic rod 12 in the device, causing it to retract and lower the traction bar 13. During the descent of the traction bar 13, it pulls the steel wire rope 14 connected to the swinging edge of the inner frame 2. Guided by the rope groove 15, the steel wire rope 14 pulls the inner frame 2, causing it to swing upwards from its initial position to a horizontal state. The steel plate to be cut is then placed smoothly on these toothed plates 3, preparing for the cutting operation. During laser cutting, the waste material, under the influence of gravity and cutting impact, gets stuck on the serrations of the serrated blade plate 3. After cutting, the two bidirectional lead screws 6 rotate, causing the two sliders 7, threaded to each other on the same side, to move away from each other. During the movement of the sliders 7, their outward-protruding sides slide within the inclined groove 10. Since the inclined groove 10 is located on the upward-extending surface of the connecting frame 5, and the connecting frame 5 is fixedly connected to the bottom of the insert shell 4 on both sides, the movement of the sliders 7 causes the connecting frame 5 to rise. As the connecting frame 5 rises, it causes the insert shell 4 to rise synchronously until the top edge of the insert shell 4 is flush with the top edge of the serrated blade plate 3. At this point, the flat surface of the top edge of the insert shell 4 replaces the serrations of the serrated blade plate 3, thus supporting the waste material. After the waste material is transferred to the top edge of the insert 4, the hydraulic rod 12 is activated again to extend and push the traction bar 13 upward. During the upward movement of the traction bar 13, the downward pull on the wire rope 14 is released. At this time, the inner frame 2 naturally swings down under its own weight. As the inner frame 2 swings down, the waste material placed on the top edge of the insert 4 naturally slides off under gravity and detaches from the upper surface of the inner frame 2, thus completing the waste material cleaning work.

[0023] The wiring diagrams of the motor and hydraulic rod 12 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the motor and hydraulic rod 12 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
