[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] like Figures 1 to 6 As shown, Embodiment 1 of this utility model provides a debris cleaning device, including a debris receiving hopper 4, a lifting frame 6, a rotating shaft 7, and a brushing unit 8. Figure 2 As shown, the support platform 3 has a rectangular structure, and clearance grooves 5 are provided on the frame 2 around it. Figure 1As shown, the slag hopper 4 is fixed to the frame 2 below the support platform 3 to collect debris falling from the support platform 3. The clearance groove 5 is a rectangular frame containing two parallel horizontal grooves 51 and two parallel vertical grooves 52. The horizontal grooves 51 and vertical grooves 52 are perpendicular. The lifting frame 6 consists of two horizontal bars 61 and two vertical bars 62. The horizontal bars 61 are located in the horizontal grooves 51, and the vertical bars 62 are located in the vertical grooves 52. Therefore, the lifting frame 6 is completely outside the support platform 3, and the lifting frame 6 rises and falls in the clearance groove 5 without being interfered with by the support platform 3.

[0034] like Figure 3 As shown, two linear reciprocating drive mechanisms are respectively provided at both ends of the lifting frame 6. In this embodiment, the linear reciprocating drive mechanism used is a lead screw 9 slider mechanism. Specifically, the linear reciprocating drive mechanism includes a lead screw 9 and a movable seat 10. The lead screw 9 is rotatably mounted on the crossbar 61 of the lifting frame 6 via a bearing seat, while the movable seat 10 is sleeved on the lead screw 9 and threadedly engaged with it. The two lead screws 9 are parallel. Both ends of the rotating shaft 7 are rotatably mounted on the two movable seats 10, one of which has a motor 18 fixedly mounted. The motor 18 can drive the rotating shaft 7 to rotate on the movable seat 10.

[0035] Since the rotating shaft 7 is perpendicular to the two lead screws 9, the two movable seats 10 are limited by the rotating shaft 7, preventing the movable seats 10 from rotating due to the rotation of the lead screws 9. Therefore, when the lead screws 9 rotate, the movable seats 10 can be driven to move on the lead screws 9. To enable the movable seats 10 on the two lead screws 9 to move in the same direction at the same speed, this utility model has a transmission rod 11 rotatably mounted on the vertical rod 62 of the lifting frame 6, perpendicular to the lead screws 9. The ends of the two lead screws 9 are respectively connected to the two ends of the transmission rod 11 through two bevel gear sets 12. It should be noted that although the transmission rod 11 can realize the transmission between the two lead screws 9, there are two ways to make the two movable seats 10 move in the same direction at the same speed. One way is that the transmission rod 11 makes the two lead screws 9 rotate in the same direction at the same speed, and the helix direction of the two lead screws 9 is also the same; the other way is that the transmission rod 11 makes the two lead screws 9 rotate in opposite directions at the same speed, and the helix direction of the two lead screws 9 is opposite. This utility model embodiment adopts the second form. When the transmission rod 11 rotates, it drives the two lead screws 9 to rotate at the same speed through the two bevel gear sets 12, so that the moving seat 10 moves along the lead screws 9 at the same speed and in the same direction, thereby driving the rotating shaft 7 to perform linear reciprocating motion.

[0036] Since the rotating shaft 7 can be driven to rotate by the motor 18, when the rotating shaft 7 moves along the lead screw 9, the multiple brushing units 8 on the rotating shaft 7 can rotate and clean the serrated support bars 16 on the brushing support platform 3, sweeping the debris into the slag receiving hopper 4 below. A slag storage tray 17 is also placed below the slag receiving hopper 4, and the debris falling from the slag receiving hopper 4 enters the slag storage tray 17. The slag storage tray 17 can be directly pulled out from the bottom of the frame 2 for unified processing of the collected debris.

[0037] Embodiment two

[0038] On the basis of embodiment one, the lifting frame 6 of the utility model realizes lifting through the following structure. Firstly,

[0039] Four guide sleeves 13 are fixed in the accommodation slot 5, and a guide rod 14 is slidingly installed in each guide sleeve 13. The top of the guide rod 14 is fixedly connected with the lifting frame 6. The four guide rods 14 are parallel. This guide structure makes the lifting frame 6 more stable during lifting, avoiding the shaking or deviation of the lifting frame 6 in the accommodation slot 5.

[0040] Meanwhile, two electric push rods 15 are fixed in the accommodation slot 5, and the two electric push rods 15 are located in the two vertical grooves 52. The electric push rod 15 is parallel with the guide rod 14, and the movable end of the electric push rod 15 is fixedly connected with the lifting frame 6. In this way, the axial lifting of the lifting frame 6 along the guide rod 14 can be accurately controlled through the extension and retraction of the electric push rod 15, and the lifting height of the lifting rod can be adjusted.

[0041] When it is necessary to clean the debris, the electric push rod 15 pushes the lifting frame 6 to rise, so that the rotating shaft 7 and the sweeping unit 8 extend out of the accommodation slot 5 and reach above the support table 3. The motor 18 drives the rotating shaft 7 to rotate, and the screw rod 9 rotates under the drive of the other motor 18, so as to drive the rotating shaft 7 to move along the screw rod 9, and the sweeping unit 8 performs cleaning work on the support table 3; when the cleaning is completed, the electric push rod 15 is retracted, so that the lifting frame 6 is lowered into the accommodation slot 5, and the rotating shaft 7 and the sweeping unit 8 are lowered into the accommodation slot 5, so as to ensure that the device is completely below the upper surface of the support table 3 and does not affect the normal cutting of the laser cutting machine 1 on the metal plate.

[0042] Embodiment three

[0043] On the basis of embodiment one and embodiment two, embodiment three of the utility model further designs the sweeping unit 8. The rotating shaft 7 is fixed with the same number of sweeping units 8 as the sawtooth support strips 16. Figure 6 As shown in the figure, each sweeping unit 8 comprises a fixed sleeve 81 and two circles of steel wire brushes 82 arranged on the fixed sleeve 81. The fixed sleeve 81 comprises two half rings 811 hinged through a hinge shaft, and the two half rings 811 are matched and buckled on the rotating shaft 7 and fixedly connected through bolts. This design makes the fixed sleeve 81 in each sweeping unit 8 separately detachable. When the steel wire brush 82 of a certain sweeping unit 8 is seriously worn, only the bolts on the fixed sleeve 81 need to be loosened, the worn fixed sleeve 81 and steel wire brush 82 are taken off, and the new fixed sleeve 81 and steel wire brush 82 are replaced, and then the bolts are fixed again. This detachable structure not only reduces the maintenance cost, but also prolongs the service life of the device.

[0044] As shown in the figure, Figure 6As shown, two turns of the steel wire brush 82 on each brushing unit 8 are symmetrically arranged, and the steel wire brush 82 is conically arranged around the fixed sleeve 81, which makes the steel wire brush 82 brush the sawtooth support bar 16 at a certain angle with the corresponding sawtooth support bar 16, rather than being parallel to the sawtooth support bar 16, so that the sawtooth support bar 16 can be more fully brushed.

[0045] Through the above arrangement, in the debris cleaning work, the lifting frame 6 is stably lifted under the cooperation of the electric push rod 15 and the guide sleeve 13 and the guide rod 14, and the linear reciprocating driving mechanism drives the rotating shaft 7 to drive the brushing unit 8 to clean the debris on the support table 3. When the brushing unit 8 needs to be replaced, single disassembly and assembly operation can be conveniently and quickly performed. The mutual cooperation between the structures of the whole device not only guarantees the cleaning effect, but also improves the practicability and maintainability of the device.

[0046] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies thereof, the present application also intends to include these modifications and variations.
