Description

Technical Field

[0001] This utility model relates to the field of laser cutting device technology, specifically to a laser cutting device with a waste chip collection function. Background Technology

[0002] Metal castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after cooling and subsequent processing such as grinding.

[0003] Laser cutting uses a high-power-density laser beam to irradiate the material being cut, quickly heating the material to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf, thus completing the cutting of the material.

[0004] In the processing of metal castings, laser cutting equipment is required to cut the castings. During the cutting process, a large amount of waste chips and scrap are generated. Current technology generally uses a collection box to collect the waste. When the collection box is full, it needs to be replaced in time. The replacement process requires stopping the machine, otherwise the waste will fall on the ground, affecting the working environment. The dust is also harmful to human health. Stopping the machine will affect production efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a laser cutting device with waste collection function to solve the problem of downtime and reduced production efficiency caused by replacing the collection box when laser cutting generates waste in the prior art.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figures 1 to 4 This embodiment provides a laser cutting device with waste collection function, which includes a worktable 1, a hopper 2, a waste collection cart 3, a baffle plate 4, a spring unit 5, and a push rod 6. A laser head is fixed on the worktable 1 for laser cutting the material on the worktable 1. The hopper 2 is used to collect the waste generated by laser cutting. The waste collection cart 3 is used to collect the waste in the hopper 2. The baffle plate 4 is used to open or close the hopper 2. The spring unit 5 is used to reset the baffle plate 4. The push rod 6 is used to push the baffle plate 4.

[0023] A waste inlet is provided on the upper surface of the worktable 1. A collection hopper 2 is fixed below the worktable 1 and communicates with the waste inlet. A discharge port is provided below the collection hopper 2. A receiving space is formed below the worktable 1 to accommodate the waste collection cart 3. Preferably, the laser cutting device with waste collection function also includes fixing blocks 11. Multiple fixing blocks 11 are bolted to the upper surface of the worktable 1. One end of the fixing block 11 contacts the worktable 1, and the other end contacts the workpiece.

[0024] A baffle plate 4 is installed at the discharge port, with one end hinged to the collection hopper 2 and the other end connected to the elastic unit 5. The elastic unit 5 is used to pull the baffle plate 4 to move in the direction of blocking the discharge port. When the baffle plate 4 is closed, waste will accumulate in the collection hopper 2. When the baffle plate 4 is open, waste will be discharged from the discharge port. The collection hopper 2 has a small capacity and is generally only suitable for collecting waste for a short time. Waste will only accumulate during the interval between changing the waste collection vehicle 3. Preferably, the elastic unit 5 is a spring, with one end connected to the baffle plate 4 and the other end connected to the collection hopper 2.

[0025] The waste collection vehicle 3 can move into or out of the receiving space. The push rod 6 is fixed to the upper side of the waste collection vehicle 3. When the waste collection vehicle 3 moves into the receiving space, the push rod 6 pushes the upper side of the baffle plate 4 to open the discharge port. Specifically, the laser cutting device with waste collection function also includes a mounting column 7. The two ends of the mounting column 7 are respectively hinged to the lower end of the collection hopper 2. The baffle plate 4 is fixedly connected to the mounting column 7. When the waste collection vehicle 3 moves into the receiving space, the push rod 6 will contact the baffle plate 4. When it moves further, the push rod 6 will push the baffle plate 4 to rotate, opening the discharge port, and the waste in the collection hopper 2 will be unloaded and fall into the waste collection vehicle 3. Preferably, the laser cutting device with waste collection function also includes a push wheel 9. The push wheel 9 is fixed to the push rod 6 and can contact the upper side of the baffle plate 4, thereby changing the sliding friction of the push rod 6 into the rolling friction of the push wheel 9.

[0026] Preferably, the laser cutting device with waste collection function further includes two sets of drive gears 8, mounting columns 7, and baffle plates 4. The two mounting columns 7 are respectively fixedly connected to the two drive gears 8, which are meshed together. When the baffle plate 4 on the side closer to the waste collection vehicle 3 is pushed open, the mounting column 7 connected to it rotates, driving the drive gear 8 to rotate. Simultaneously, it drives the other set of drive gears 8, mounting columns 7, and baffle plates 4 to rotate, and the baffle plate 4 on the other side also opens. Moving the push rod 6 the same distance results in a smaller rotation angle for a single baffle plate 4 than for both sets of baffle plates 4. This is because the hinge point positions of the baffle plates 4 are different in the two cases. When the discharge port is large, a design with two sets of baffle plates 4 can be adopted to increase the rotation angle of the baffle plates 4, making waste discharge smoother. It should be noted that, generally, to prevent waste from falling through the gap between the two mounting columns 7, a baffle can be installed above the two mounting columns 7 to block it.

[0027] Preferably, the side of the baffle plate 4 away from the hinge is bent downwards, which facilitates the insertion of the push rod 6 or the push wheel 9.

[0028] Preferably, two sets of push wheels 9 and push rods 6 are horizontally arranged and push on both sides of the baffle plate 4 respectively.

[0029] Preferably, the laser cutting device with waste collection function also includes a buffer pad 10, which is fixed below the collection hopper 2. The buffer pad 10 is ring-shaped and surrounds the outer perimeter of the discharge port. The buffer point can provide buffering after the baffle plate 4 is reset, and can also prevent waste from falling from the gap between the baffle plate 4 and the collection hopper 2.

[0030] In summary, the laser cutting device with waste collection function provided by this utility model uses a collection hopper 2 as a container for short-term waste collection. After the waste collection cart 3 is pushed into the receiving space, the push rod 6 will push the baffle plate 4 to rotate, opening the discharge port, and the waste will be discharged from the discharge port. When the waste collection cart 3 is removed, the push rod 6 disengages from the baffle plate 4, and the baffle plate 4 is reset under the action of the elastic unit 5, closing the discharge port. The waste cannot be discharged and accumulates in the collection hopper 2 until a new waste collection cart 3 is replaced. The entire process does not cause waste to fall to the ground, and the machine does not need to be stopped.

[0031] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
