Description

Technical Field

[0001] The utility model relates to the technical field of waste collection, in particular to a laser cutting waste collection device. Background Art

[0002] Laser cutting machine is a common sheet metal processing equipment. Laser cutting uses a laser beam to irradiate the surface of the material, causing it to be quickly heated to the vaporization temperature, evaporating to form holes. As the laser beam moves, the holes continuously form a very narrow slit to complete the cutting of the material. The laser cutting machine has a hollow metal workbench. When using the laser cutting machine to cut metal sheets, the metal sheet is placed on the workbench and then cut into a specific shape.

[0003] A Chinese utility model patent with publication number (CN219945002U) discloses a laser cutting waste collection device, including a box body, which is arranged below the workbench of the laser cutting machine, a long filter plate is hingedly arranged on the left inner wall of the box body, and a short filter plate is hingedly arranged on the right inner wall of the box body, and the bottom of the long filter plate is placed on the short filter plate, and the two form a V-shaped distribution. The eccentric wheel vibrates the short filter plate, so that the waste plate in the waste falls onto the long filter plate and the short filter plate, and the waste powder in the waste falls from the filter hole onto the waste powder receiving plate, thereby realizing the separation and collection of waste and waste powder.

[0004] However, there are still some defects. For example, the waste material and waste powder are vibrated and screened by using a long filter plate and a short filter plate arranged in a V shape. However, as the screening proceeds, the waste material gathers at the lowest point. When the material is further discharged at this position, it becomes difficult to effectively separate the waste powder from the waste material, thereby reducing the separation efficiency of the waste material and waste powder when the waste material is collected.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The laser cutting waste collection device according to an embodiment of the present utility model is described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the laser cutting waste collection device according to the embodiment of the present invention may include a workbench 10 , a receiving box 20 , a collection box 30 and a separation mechanism 40 .

[0023] Wherein, a hollow support plate 11 is arranged on the surface of the workbench 10;

[0024] The material receiving box 20 is arranged below the hollow support plate 11, and a material receiving hopper 21 and a material discharging plate 22 are sequentially arranged in the upper and lower parts of the material receiving box 20. The top end of the material discharging plate 22 is inclined toward the bottom of the material receiving hopper 21, and the bottom end of the material discharging plate 22 passes through the material receiving box 20 and is arranged in the collecting box 30. The separation mechanism 40 is arranged between the material receiving hopper 21 and the material discharging plate 22.

[0025] It is understandable that the waste material falling from the hollow support plate 11 during laser cutting can directly enter the receiving hopper 21, and then the waste material and waste powder are separated through the separation mechanism 40, and the separated waste material finally enters the collection box 30 from the discharge plate 22, and the waste powder enters the waste powder box 43. In the process, the waste powder on the waste material can be effectively separated, avoiding the situation where the waste material is difficult to separate due to the accumulation of waste material, thereby improving the efficiency and quality of waste collection.

[0026] The separation mechanism 40 may include a filter screen 41 , a feeding wheel 42 , a waste powder box 43 and a linkage 44 .

[0027] Among them, the filter screen 41 is set in a lower arc shape, and one end of the filter screen 41 is set below the bottom end of the receiving hopper 21, and the other end of the filter screen 41 is set below the top of the discharge plate 22. One side of the filter screen 41 is horizontally set in the receiving box 20 through a spring 411, and the other side of the filter screen 41 is provided with multiple movable shafts 412, and the movable shafts 412 are movably set through the receiving box 20.

[0028] The feeding wheel 42 is arranged at the virtual center of the filter screen 41, and a plurality of rotating wheels 421 are evenly distributed on the outer circumference of the feeding wheel 42, and both ends of the feeding wheel 42 are arranged in the receiving box 20 through the rotating shaft 422 and the driving component 423, and the rotating shaft 422 penetrates the receiving box 20. Baffles 424 are arranged on both sides of the feeding wheel 42, and the output ends of the rotating shaft 422 and the driving component 423 are respectively movably penetrated through the adjacent baffles 424, and the filter screen 41 is slidably arranged at the bottom of the baffle 424.

[0029] It is understandable that the filter screen 41 can be driven by the movable shaft 412 to reciprocate horizontally and stably at the bottom of the baffle 424 .

[0030] It should be noted that a certain gap is left between the rotating wheel 421 and the filter screen 41 described in this embodiment, which can not affect the pushing of the waste in the filter screen 41 by the rotating wheel 421 and at the same time facilitate the reciprocating motion of the filter screen 41.

[0031] It should be noted that the driving component 423 described in this embodiment can be a reduction motor, a servo motor, etc. The driving component 423 can drive the feeding wheel 42 to rotate, so that the rotating wheel 421 can transfer the waste materials in the receiving hopper 21 to the filter screen 41 in batches.

[0032] The waste powder box 43 is arranged below the filter screen 41 , and the linkage member 44 is respectively connected to the rotating shaft 422 and one of the moving shafts 412 .

[0033] It should be noted that the linkage member 44 described in this embodiment can convert the power of the rotation of the rotating shaft 422 into a power source for the reciprocating movement of the moving shaft 412, thereby reducing costs.

[0034] It is understandable that when the linkage 44 drives the movable shaft 412 connected thereto to move back and forth, the movable shaft 412 can drive other movable shafts 412 to push / pull the filter screen 41 horizontally. The arrangement of multiple movable shafts 412 helps to stabilize the reciprocating movement of the filter screen 41.

[0035] Specifically, when actually collecting the waste (waste and waste powder) that has fallen from the hollow pallet 11, the relevant personnel first start the driving component 423, so that the driving component 423 drives the feeding wheel 42 to rotate, so that the rotating wheel 421 can transfer the waste from the receiving hopper 21 to the filter screen 41 in batches, so as to be able to separate and collect the waste that has fallen from the hollow pallet 11 in sequence.

[0036] The rotation of the feeding wheel 42 can drive the rotating shaft 422 to rotate. While the rotating shaft 422 rotates, it can drive the movable shaft 412 connected thereto to move back and forth through the linkage 44, so that the movable shaft 412 drives the filter screen 41 to move back and forth, so as to realize the screening of the waste material in the filter screen 41. The screened waste powder enters the waste powder box 43 through the sieve holes of the filter screen 41. The waste material can enter the discharge plate 22 from the other end of the filter screen 41 under the action of the rotating wheel 421, and then be collected in the collection box 30.

[0037] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the linkage member 44 may include a connecting rod 441, a rack 442 and a gear 443, wherein the two ends of the connecting rod 441 are movably connected to the eccentric side of the rotating shaft 422 and the rack 442 respectively. The rack 442 is slidably arranged on the outer wall of the receiving box 20, the rack 442 is perpendicular to the moving shaft 412, and the rack 442 is meshed with the gear 443. The gear 443 is threadedly sleeved on the outer side of one of the moving shafts 412.

[0038] The receiving box 20 is movably provided with a connecting sleeve 23, which is connected to the gear 443. It is understandable that the setting of the connecting sleeve 23 can limit the gear 443, ensure the connection between the gear 443 and the rack 442 and the movable shaft 412, and contribute to the smooth operation of the gear 443.

[0039] Specifically, the rotation of the rotating shaft 422 can drive the rack 442 to move back and forth through the connecting rod 441. Under the action of the rack 442, the gear 443 rotates back and forth. When the gear 443 rotates, the inner moving shaft 412 can move back and forth longitudinally. During this process, the spring 411 buffers the filter screen 41, thereby realizing the reciprocating movement function of the filter screen 41.

[0040] In summary, the laser cutting waste collection device of the embodiment of the utility model can sequentially separate and collect the waste materials dropped from the hollow support plate. During the process, the filter screen and the feed wheel can effectively separate the waste powder on the waste materials into the waste powder box in batches, avoiding the situation where waste materials are difficult to separate due to waste powder accumulation, thereby improving the efficiency and quality of waste collection.
