Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to an automatic waste collection device for sheet metal processing. Background Technology

[0002] In the fields of automobile manufacturing, machining, and electronic equipment, sheet metal cutting is one of the core processes. Laser cutting, plasma cutting, and CNC punching are commonly used to achieve precise forming of sheet metal parts. During the cutting process, irregular scraps and small particles of waste are generated, including metal chips with a diameter of 0.1-2mm and metal powder generated by the high temperature of cutting.

[0003] The existing equipment does not have a differentiated collection structure designed for the physical characteristics of irregular scraps and fine particles. The two types of waste are always collected together. In order to achieve waste sorting and recycling, additional manual sorting or special screening equipment is required. Moreover, fine particles are easy to be scattered again during the sorting process, which increases operating costs and labor intensity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic waste collection device for sheet metal processing.

[0005] The automatic waste collection device for sheet metal processing provided by this utility model adopts the following technical solution:

[0006] An automatic waste collection device for sheet metal processing includes a main frame, a serrated plate, a gantry frame, and a cutting head. The serrated plate is mounted on the main frame, the gantry frame spans the main frame, and the cutting head is mounted on the gantry frame. It also includes an automatic material distribution mechanism and a waste bin. The automatic material distribution mechanism is located below the serrated plate, and the waste bin is located below the automatic material distribution mechanism. The automatic material distribution mechanism includes a motor, a conveyor belt, a gear set, two chains, and connecting components. The gears of the gear set mesh with the two chains. The output end of the motor is connected to one of the gears in the gear set. When the motor drives the gear to rotate, the chains rotate cyclically. Several connecting components are provided, each fixed at intervals to the two chains. The conveyor belt is fixed in the middle of the connecting components and is located below the serrated plate. The conveyor belt has fine holes, and the connecting components drive the conveyor belt to vibrate.

[0007] Optionally, the connecting assembly includes a docking component, a fixing block, a connecting block, a slider, and a connecting rod. The docking component is fixed on the chain, the fixing block is disposed on the docking component, the connecting block is disposed on the fixing block, the connecting block is provided with a limiting groove, the slider slides in the limiting groove along a fixed direction, the connecting rod is fixed on the slider, and one end of the connecting rod is fixed to the side edge of the conveyor belt.

[0008] Optionally, springs are connected to both ends of the slider, and the other end of the spring is connected to the inner wall of the limiting groove.

[0009] Optionally, an annular block is provided inside the main frame, and a wavy groove is provided on the annular block. A roller is connected to the end of the connecting rod away from the conveyor belt. The roller is inserted into the wavy groove. When the chain drives the connecting block to move, the roller at the end of the connecting rod moves accordingly in the wavy groove.

[0010] Optionally, a fixing plate is provided on the inner wall of the main frame, a track is provided on the fixing plate, and two sets of rollers are provided on the fixing block, which are rotatably connected to the back of the fixing block, and the two sets of rollers are engaged on the track.

[0011] Optionally, the surface of the conveyor belt is provided with anti-slip texture, which extends along the width direction of the conveyor belt to increase the friction between irregular scraps and the surface of the conveyor belt and prevent the irregular scraps from sliding and shifting when the conveyor belt vibrates.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. As the connecting components move with the chain, the conveyor belt vibrates continuously. During this vibration, small particles adhering to the irregular scraps are shaken off. These particles fall into the waste bin through the fine holes in the conveyor belt, thus separating the scraps from the small particles. As the chain continues to drive, the conveyor belt transports the cleaned irregular scraps to the designated scrap collection area, where they can be directly taken out for centralized recycling. The entire process requires no manual intervention, achieving automation and continuity of waste collection.

[0014] 2. When the chain drives the connecting block to move, the roller at the end of the connecting rod moves in the wavy groove. The connecting rod is fixed on the slider, and the slider can only move in a fixed direction in the limiting groove. This causes the connecting rod to move up and down, so that the conveyor belt vibrates vertically while moving horizontally with the chain. This method ensures that the conveyor belt is evenly stressed on both sides and as a whole, with strong vibration synchronization. The uniform vibration can cover the entire area of ​​the conveyor belt, avoiding dead corners of local vibration. This ensures that all small particles on the surface of the scrap material can be effectively shaken off, further improving the thoroughness of waste separation.

[0015] 3. The track on the fixed plate and the two sets of opposing rollers on the back of the fixed block form a locking guide, which can strictly limit the movement direction of the fixed block, allowing the fixed block to move only along the extension direction of the track, preventing the fixed block from shifting left or right or swaying back and forth in the horizontal direction, ensuring that the connecting components always move smoothly along the preset path, thereby ensuring that the conveyor belt does not deviate when horizontally transporting scrap materials, preventing scrap materials from falling from the edge of the conveyor belt, and improving the continuity of the collection process.

[0024] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] This utility model discloses an automatic waste collection device for sheet metal processing. (Refer to...) Figure 1-5 An automatic waste collection device for sheet metal processing includes a main frame 1, a toothed plate 2, a gantry frame 3, and a cutting head. The toothed plate 2 is mounted on the main frame 1 and is used to support the sheet metal to be cut. The gantry frame 3 spans the main frame 1, and the cutting head is mounted on the gantry frame 3.

[0026] It also includes an automatic material sorting mechanism 5 and a waste bin 4. The automatic material sorting mechanism 5 is located below the sawtooth plate 2, and the waste bin 4 is located below the automatic material sorting mechanism 5. The automatic material sorting mechanism 5 includes a motor 51, a conveyor belt 52, a gear set, two chains 53, and a connecting assembly 54. The gears of the gear set mesh with the two chains 53 respectively. The output end of the motor 51 is connected to one of the gears in the gear set. When the motor 51 drives the gear to rotate, the chain 53 rotates cyclically accordingly. Several connecting assemblies 54 are provided, and several connecting assemblies 54 are fixed at intervals on the two chains 53. The conveyor belt 52 is fixed in the middle of the connecting assembly 54 and is located below the sawtooth plate 2. The conveyor belt 52 is equipped with fine holes, and the connecting component 54 drives the conveyor belt 52 to vibrate. Through this design, as the connecting component 54 moves with the chain 53, the conveyor belt 52 generates continuous vibration. During the vibration, the small particles adhering to the irregular scraps are shaken off. These particles fall further into the waste bin 4 through the fine holes on the conveyor belt 52, realizing the separation of scraps and small particles. With the continuous transmission of the chain 53, the conveyor belt 52 transports the cleaned irregular scraps to the designated scrap collection area, where they can be directly taken out for centralized recycling. The whole process does not require manual intervention, realizing the automation and continuity of waste collection.

[0027] The connecting assembly 54 includes a docking part 540, a fixing block 541, a connecting block 542, a slider 543, and a connecting rod 544. The docking part 540 is fixed to the chain 53. The fixing block 541 is disposed on the docking part 540. The connecting block 542 is disposed on the fixing block 541. The connecting block 542 is provided with a limiting groove 545. The slider 543 slides in a fixed direction within the limiting groove 545. The connecting rod 544 is fixed to the slider 543. One end of the connecting rod 544 is fixed to the side edge of the conveyor belt 52. An annular block 6 is provided inside the main frame 1. The annular block 6 is provided with a wavy groove 61. The end of the connecting rod 544 away from the conveyor belt 52 is connected to a roller 547. The roller 547 is inserted into the wavy groove. When the chain 53 drives the connecting block 542 to move within the wavy groove 61, the roller at the end of the connecting rod 544 moves accordingly within the wavy groove 61. The connecting rod 544 is fixed on the slider 543, which can only move in a fixed direction within the limiting groove 545. This results in the up-and-down movement of the connecting rod 544, causing the conveyor belt 52 to vibrate vertically while moving horizontally with the chain 53. This method ensures that the conveyor belt 52 is subjected to uniform force on both sides and as a whole, with strong vibration synchronization. The uniform vibration can cover the entire area of ​​the conveyor belt 52, avoiding dead zones of local vibration and ensuring that all small particles on the surface of scrap materials can be effectively shaken off, further improving the thoroughness of waste separation.

[0028] A fixing plate 7 is provided on the inner wall of the main frame 1. A track 71 is provided on the fixing plate 7. Two sets of rollers 548 are provided on the fixing block 541. The rollers 548 are rotatably connected to the back of the fixing block 541. The two sets of rollers 548 are engaged with the track 71. The track 71 on the fixing plate 7 and the two sets of rollers 548 on the back of the fixing block 541 form a locking guide, which can strictly limit the movement direction of the fixing block 541. The fixing block 541 is only allowed to move along the extension direction of the track 71, which prevents the fixing block 541 from shifting left and right or swaying back and forth in the horizontal direction. This ensures that the connecting component 54 always moves smoothly along the preset path, thereby ensuring that the conveyor belt 52 does not deviate when horizontally conveying scrap materials, preventing scrap materials from falling from the edge of the conveyor belt 52, and improving the continuity of the collection process.

[0029] The surface of the conveyor belt is provided with anti-slip textures that extend along the width of the conveyor belt. These textures are used to increase the friction between irregular scraps and the surface of the conveyor belt, preventing the irregular scraps from sliding or shifting when the conveyor belt vibrates.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
