Description

Technical Field

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

[0002] Laser cutting generates a large amount of waste. Existing waste collection devices for laser cutting machines, such as the one disclosed in Chinese Patent Publication No. CN215880328U and the one disclosed in Chinese Patent Publication No. CN222569640U, all involve installing a collection trough below the processing area of ​​the laser cutting machine (composed of several evenly spaced support bars). The trough's base plate is inclined vertically, and a collection box is installed at the lower end of the base plate. The entire waste collection process is as follows: the waste falls through the gaps between the support bars onto the base plate of the collection trough, and then is guided by the base plate into the collection box. However, this type of collection device is only suitable for small-sized waste. If the waste size is larger than the gap between two adjacent support bars, the waste will remain above the support bars, still requiring manual handling.

[0003] To address this, we designed a waste collection device for laser cutting machines. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a waste collection device for laser cutting machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waste collection device for laser cutting machines, comprising: The fixing unit includes a fixing frame, a plurality of fixing rods spaced apart along the length of the fixing frame, and a fixing plate disposed at the upper end of each fixing rod; the height of the fixing rods decreases along the length of the fixing frame, and the fixing plate is located directly below the support bar of the laser cutting machine. The lifting unit, located outside the fixed unit, includes a lifting frame, multiple lifting struts spaced apart along the length of the lifting frame, and a lifting plate located at the upper end of each lifting strut; the height of the lifting struts decreases along the length of the lifting frame, and the lifting plate and the fixed plate are arranged alternately, with their top surfaces forming a continuous guide slope. The drive device is connected between the fixed unit and the lifting unit. It is used to drive the lifting unit to rise vertically and pass through the gap of the support bars. Its top surface forms a separate waste guide channel. The collection box, located at the end of the laser cutting machine, includes a scrap collection chamber and a whole material collection chamber, both of which have an open structure at the top.

[0006] Furthermore, the top surface of the fixed support plate forms a smooth transition surface with the top surface of the adjacent lifting support plate, and the thickness of the fixed support plate is greater than the thickness of the support strip.

[0007] Furthermore, the tilt angle of the top surface of the fixed support plate is greater than the tilt angle of the top surface of the lifting support plate.

[0008] Furthermore, the fixing unit is surrounded by a panel, which is open at one end facing the collection box and closed on the other side.

[0009] Furthermore, the fixed support plate and the lifting support plate decrease in height from the outside to the inside along their own length direction.

[0010] Furthermore, the opening end of the whole material collection chamber is higher than the opening end of the broken material collection chamber, and the side of the opening end of the whole material collection chamber is provided with an outwardly extending receiving lip.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. It can guide and collect small-sized waste materials falling through the gaps between the support bars by forming a continuous flow guide slope through the interlacing of the fixed support plate and the lifting support plate. Under the action of the drive equipment, the lifting support plate can pass through the gaps between the support bars to form a waste material guide channel to guide and collect large-sized waste materials stuck above the support bars. 2. The design of the fixed support plate tilt angle being greater than that of the lifting support plate creates a certain height gradient between adjacent fixed support plates in the waste diversion channel, preventing large-sized waste from getting stuck during the diversion process.

[0015] Example 1, in conjunction with Appendix Figure 1-5 A waste collection device for laser cutting machines includes a fixing unit, a lifting unit, a drive device 7, a collection box 8, and a surrounding plate 9.

[0016] The fixing unit is installed below the processing area of ​​the laser cutting machine; it includes: Fixed frame 1 is horizontally positioned below the laser cutting machine support bar 100; Multiple fixed support rods 2 are welded at intervals along the length of the fixed frame 1, and their height decreases from the outside to the inside. A fixed support plate 3 is welded to the upper end of the fixed support rod 2, and its thickness is greater than that of the support bar 100. Each fixed support plate 3 is directly below the support bar 100. Preferably, the thickness of the fixed support plate 3 is 2-3 mm thicker than that of the support bar 100.

[0017] Preferably, each fixed support plate 3 corresponds to two fixed support rods 2 to ensure the stability of the fixed support plate 3; furthermore, the fixed support plate 3 is connected to the upper end of the fixed support rod 2 near its end.

[0018] The lifting unit includes: The lifting frame 4 is arranged parallel to the outside of the fixed frame 1; The lifting support rods 5 are spaced along the length of the lifting frame 4, and their height gradient matches that of the fixed support rods 2. The lifting support plate 6 is fixed to the upper end of the lifting support rod 5, and its width is adapted to the distance between two adjacent fixed support plates 3, so that the top surface of the fixed support plate 3 and the top surface of the adjacent lifting support plate 6 form a smooth transition surface. Preferably, the thickness of the lifting support plate 6 is 0.2-0.5mm smaller than the distance between two adjacent fixed support plates 3.

[0019] The driving device 7 is a hydraulic cylinder or a pneumatic cylinder, the cylinder body is fixed to the side wall of the fixed frame 1, and the piston rod is connected to the lifting frame 4.

[0020] The collection box 8 has a scrap collection chamber 81 with an open top and a solid material collection chamber 82. The front end of the solid material collection chamber 82 is provided with a horizontally extended receiving lip 821 for receiving large-sized waste materials.

[0021] The enclosure 9 covers three sides (left, right and front) of the fixed unit, with the rear end facing the collection box 8 open; that is, when the lifting unit is in the lowest position, the enclosure 9 covers both the three sides of the fixed unit and the three sides of the lifting unit.

[0022] Workflow: First waste collection state (small-sized waste collection state): The drive device 7 lowers the lifting unit to the lowest position. At this time, the lifting support plate 6 and the fixed support plate 3 are arranged alternately, and their top surfaces together form a continuous guide slope. The scrap generated during processing falls through the gap of the support bar 100 to the continuous guide slope and slides into the scrap collection chamber 81 along the continuous guide slope. The surrounding plate 9 prevents the scrap from overflowing to the side.

[0023] The second waste collection state (large-size waste collection state): After processing is completed, the finished material is removed, and then the drive equipment 7 lifts the lifting unit. The lifting support plate 6 passes through the gap of the support bar 100 and protrudes from the top surface of the laser cutting machine processing area. At this time, large-sized waste materials slide down along the waste guide channel formed by the lifting support plate 6 alone, and are guided by the receiving lip 821 to the whole material collection cavity 82.

[0024] Furthermore, to prevent large-sized waste materials from being blocked by the edges of the lifting support plate 6 during the waste material flow channel, the inclination angle of the top surface of the fixed support plate 3 is greater than the inclination angle of the top surface of the lifting support plate 6. That is, the plane containing the top surface of the front lifting support plate 6 is located above the plane containing the top surface of the rear lifting support plate 6, as shown in the attached figure. Figure 5 As shown.

[0025] Example 2, in conjunction with Appendix Figure 6 A waste collection device for laser cutting machines, differing from Embodiment 1 in that: the fixed support plate 3 and the lifting support plate 6 decrease in height from the outside to the inside along their own length; for example, a downwardly concave arc or V-shaped structure. This allows waste to be collected in the center.
