Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal cutting equipment, specifically to a waste scraper for an environmentally friendly sheet metal cutting machine. Background Technology

[0002] Environmentally friendly boards are made from recycled resources such as wood chips, wood panels, and plant fibers, processed using specialized techniques and equipment. This material not only possesses excellent physical properties but also significantly reduces its environmental impact due to its reliance on renewable resources, making it widely used in modern decoration, furniture production, flooring, door panels, and wall cladding. Since environmentally friendly boards typically require cutting to achieve specific sizes and shapes, the use of efficient and precise board cutting machines is indispensable.

[0003] Patent CN215941656U discloses a debris collection device for a sheet metal cutting machine. The device includes a worktable and a cutting device for cutting sheet metal. The worktable has a collection mechanism comprising a debris collection box and a debris removal component. The debris collection box is located on the side of the worktable away from the cutting device. The debris collection box has an inner cavity, and a debris inlet is located on the side of the debris collection box away from the ground, communicating with the inner cavity. The debris removal component is mounted on the debris collection box and is used to clean debris from the sheet metal into the debris collection box. This application achieves the purpose of facilitating the collection and cleaning of debris from the sheet metal by pushing the cut sheet metal towards the debris collection box and simultaneously cleaning the debris from the sheet metal into the debris collection box using the debris removal component.

[0004] In practical applications, although existing technologies employ debris collection devices to improve the cleanliness and safety of the working environment, debris generated during board cutting still easily scatters onto the workbench surface. This is mainly because the cutter is positioned on the workbench, and the debris generated during cutting is often pushed onto the workbench rather than falling directly into the debris collection box. This situation not only causes trouble for the workers' cleaning work but may also affect subsequent cutting operations. In view of this, we propose a waste scraper for environmentally friendly board cutting machines. Utility Model Content

[0005] The purpose of this utility model is to provide a waste scraper for an environmentally friendly sheet metal cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The waste scraper of the environmentally friendly sheet metal cutting machine includes a worktable. A cutting component is provided in the middle of the rear edge of the top of the worktable. The cutting component includes an L-shaped fixing plate fixedly connected to the top of the worktable. A waste cleaning component is movably connected to the front side and near the bottom of the L-shaped fixing plate. The waste cleaning component includes a scraper.

The waste chips are guided downward into the collection box through the first discharge hopper and the second discharge hopper so that the workers can centrally process the waste chips.

[0013] Preferably, the front ends of the multiple supporting longitudinal bars are connected to a supporting transverse bar. The rear side of the supporting transverse bar is on the same plane as the front side of the inner wall of the strip-shaped chip removal hole. The supporting transverse bar can ensure that all the waste chips fall into the strip-shaped chip removal hole and prevent the waste chips from falling from the front side of the top of the workbench. Guide rods are provided on the rear side of the supporting transverse bar near the left and right ends. The scraper is slidably connected to the outside of the two guide rods, which plays a directional role in the movement of the scraper and makes the scraper move back and forth stably.

[0014] Preferably, the bottom of the scraper has multiple U-shaped clearance openings arranged equidistantly from left to right, the outer side of the support strip is in contact with the inner wall of the U-shaped clearance opening, and the bottom of the scraper is in contact with the top of the workbench, which can ensure that the scraper cleans all the waste on the top of the workbench.

[0015] Preferably, the L-shaped fixing plate is provided with a positioning component on its outer side. The positioning component includes an internally threaded fixing tube fixedly connected to the rear side of the L-shaped fixing plate. The internally threaded fixing tube is internally threaded with a threaded adjusting rod. The front end of the threaded adjusting rod passes through the rear side of the L-shaped fixing plate and is rotatably connected to a rectangular vertical tube. A limiting rod can also be provided on the rear side of the rectangular vertical tube. The rear end of the limiting rod passes through the front side of the L-shaped fixing plate, so that the rectangular vertical tube can be kept vertical. A rectangular adjusting vertical plate is movably connected inside the rectangular vertical tube. A strip positioning plate is provided at the bottom of the rectangular adjusting vertical plate. The bottom of the strip positioning plate is in contact with the top of the supporting longitudinal strip.

[0033] 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.

[0034] Please see Figures 1-8 This utility model provides a technical solution:

[0035] The waste scraper of the environmentally friendly sheet metal cutting machine, including worktable 1, such as... Figure 1 As shown, a cutting assembly 2 is provided in the middle of the rear edge of the top of the workbench 1. The cutting assembly 2 includes an L-shaped fixing plate 20 fixedly connected to the top of the workbench 1. A waste cleaning assembly 3 is movably connected to the front side of the L-shaped fixing plate 20 and near the bottom.

[0036] Combination Figure 6 and Figure 7 As shown, the waste cleaning assembly 3 includes a scraper 30, a rectangular connecting block 31 is provided in the middle of the rear side of the scraper 30, and a rectangular hole 200 is provided on the front side of the L-shaped fixing plate 20 near the bottom for the rectangular connecting block 31 to pass through. A rectangular push rod 32 is rotatably connected to the rear end of the rectangular connecting block 31. When the rectangular push rod 32 pushes the scraper 30 to move, the rectangular push rod 32 slides in the rectangular hole 200, and the outer wall of the rectangular push rod 32 fits against the inner wall of the rectangular hole 200, which can prevent the rectangular push rod 32 from shaking during use. The rectangular push rod 32 is rotatably connected to the rectangular connecting block 31, so that the rectangular push rod 32 can hang down when not in use, avoiding occupying the space behind the cutting machine.

[0037] like Figure 4 As shown, the top of the workbench 1 is provided with multiple support longitudinal bars 4 arranged equidistantly from left to right to support the environmentally friendly board material. Waste chips can be buffered between two adjacent support longitudinal bars 4, eliminating the need to clean the top of the workbench 1 after each cutting of the environmentally friendly board material, thus reducing the number of times waste chips need to be cleaned. A strip-shaped chip removal hole 10 is opened at the top of the workbench 1 near the front side. The scraper 30 scrapes the waste chips on the top of the workbench 1 forward to the strip-shaped chip removal hole 10, thereby cleaning the waste chips on the top of the workbench 1 and preventing the waste chips from affecting the subsequent cutting of the environmentally friendly board material.

[0038] In this embodiment, as Figure 5 As shown, the top of the L-shaped fixed plate 20 is equipped with a hydraulic cylinder 21. The hydraulic cylinder 21 is connected to an external hydraulic drive device. The movable rod of the hydraulic cylinder 21 passes through the top of the L-shaped fixed plate 20 and is fixedly connected to a movable horizontal plate 22. The bottom of the movable horizontal plate 22 is equipped with a movable vertical plate 23. A motor 24 is installed on the front side of the movable vertical plate 23 near the bottom via a mounting base. The motor 24 is connected to an external power source. The output shaft of the motor 24 passes through the front side of the movable vertical plate 23 and is coaxially connected to a cutting blade 25. The hydraulic cylinder 21 drives the movable horizontal plate 22 to move up and down. When the movable horizontal plate 22 moves downward, it drives the movable vertical plate 23 to move downward. The motor 24 drives the cutting blade 25 to rotate. The downward movement of the cutting blade 25 can cut the environmentally friendly board material.

[0039] The top of the movable horizontal plate 22 is provided with two positioning rods 220 arranged symmetrically front and back. The top of the positioning rods 220 passes through the bottom of the horizontal plate of the L-shaped fixed plate 20, which is conducive to the stable up and down movement of the movable horizontal plate 22.

[0040] Specifically, such as Figure 4 As shown, a strip-shaped clearance hole 11 is provided at the top of the workbench 1 and directly below the cutting blade 25. The bottom end of the cutting blade 25 can be moved into the strip-shaped clearance hole 11 to ensure that the environmentally friendly board can be cut by the cutting blade 25. The support longitudinal bar 4 above the strip-shaped clearance hole 11 also has a notch to avoid obstructing the movement of the cutting blade 25. A second hopper 7 is provided at the bottom of the workbench 1 and at the position of the strip-shaped clearance hole 11. When the scraper 30 scrapes the waste, some of the waste can fall down from the strip-shaped clearance hole 11 and be collected and discharged through the second hopper 7.

[0041] Furthermore, such as Figure 3 As shown, a first discharge hopper 6 is provided at the bottom of the workbench 1 and at the position of the strip-shaped chip discharge hole 10. The waste chips discharged from the strip-shaped chip discharge hole 10 are collected and discharged through the first discharge hopper 6. A collection box 8 is placed below the workbench 1. The bottom ends of the first discharge hopper 6 and the second discharge hopper 7 are both located above the opening of the collection box 8. The waste chips are guided downward into the collection box 8 through the first discharge hopper 6 and the second discharge hopper 7 so that the workers can collect and process the waste chips.

[0042] Furthermore, in combination Figure 1 and Figure 4 As shown, the front ends of multiple support longitudinal bars 4 are connected to support transverse bars 40. The rear side of the support transverse bars 40 and the front side of the inner wall of the strip-shaped chip discharge hole 10 are on the same plane. The support transverse bars 40 can ensure that all the waste chips fall into the strip-shaped chip discharge hole 10, and prevent the waste chips from falling from the front side of the top of the workbench 1. Guide rods 41 are provided on the rear side of the support transverse bars 40 and near the left and right ends. The scraper 30 is slidably connected to the outside of the two guide rods 41, which plays a directional role in the movement of the scraper 30, so that the scraper 30 can move back and forth stably.

[0043] Furthermore, such as Figure 6 As shown, the bottom of the scraper 30 is provided with multiple U-shaped clearance openings 300 arranged equidistantly from left to right. The outer side of the support bar 4 is in contact with the inner wall of the U-shaped clearance opening 300, and the bottom of the scraper 30 is in contact with the top of the workbench 1, which can ensure that the scraper 30 cleans up all the waste on the top of the workbench 1.

[0044] Furthermore, in combination Figure 1 and Figure 8As shown, the L-shaped fixing plate 20 is provided with a positioning component 5 on its outer side. The positioning component 5 includes an internally threaded fixing tube 50 fixedly connected to the rear side of the L-shaped fixing plate 20. The internally threaded fixing tube 50 is internally threaded with a threaded adjusting rod 51. The front end of the threaded adjusting rod 51 passes through the rear side of the L-shaped fixing plate 20 and is rotatably connected to a rectangular vertical tube 52. A limiting rod can also be provided on the rear side of the rectangular vertical tube 52. The rear end of the limiting rod passes through the front side of the L-shaped fixing plate 20, so that the rectangular vertical tube 52 can be kept vertical.

[0045] A rectangular adjusting vertical plate 53 is movably connected inside the rectangular vertical tube 52. A strip positioning plate 54 is provided at the bottom of the rectangular adjusting vertical plate 53. The bottom of the strip positioning plate 54 is in contact with the top of the supporting longitudinal bar 4. The front and rear positions of the rectangular vertical tube 52 are adjusted by adjusting the threaded adjusting rod 51, thereby adjusting the front and rear positions of the strip positioning plate 54 to adapt to different cutting widths of environmentally friendly boards. It plays a positioning role on the rear side of the environmentally friendly board so that the environmentally friendly board will not shift during cutting.

[0046] When using scraper 30 to clean the debris on top of workbench 1, the operator adjusts the rectangular adjusting plate 53 upwards so that the strip positioning plate 54 moves upwards above scraper 30, thus preventing the strip positioning plate 54 from obstructing the forward and backward movement of scraper 30.

[0047] A fastening bolt 55 is threadedly connected to the rear side and near the top of the rectangular vertical tube 52. The threaded end of the fastening bolt 55 passes through the rear side of the rectangular vertical tube 52 and abuts against the rear side of the rectangular adjusting vertical plate 53. The relative position of the rectangular adjusting vertical plate 53 and the rectangular vertical tube 52 is fixed by the fastening bolt 55, thereby fixing the position of the strip positioning plate 54.

[0048] In this embodiment, when using the waste scraper of the environmentally friendly sheet cutting machine, the operator adjusts the position of the strip positioning plate 54 according to the width of the part of the environmentally friendly sheet to be cut. Specifically, the operator rotates the threaded adjusting rod 51, causing the threaded adjusting rod 51 to move the rectangular vertical tube 52 forward or backward until the rear side of the environmentally friendly sheet is in contact with the front side of the strip positioning plate 54. At this point, the part of the environmentally friendly sheet to be cut is directly below the cutting blade 25. Then, the operator places the environmentally friendly sheet to be cut on multiple support longitudinal bars 4 and support transverse bars 40, and positions the rear side of the environmentally friendly sheet... The cutting blade 25 is aligned with the front side of the strip positioning plate 54. Then, the hydraulic cylinder 21 is operated to move the moving horizontal plate 22 downward until the bottom end of the cutting blade 25 is located in the strip clearance hole 11. Then, the motor 24 is started to drive the cutting blade 25 to rotate. After that, the staff moves the environmentally friendly board and the cutting blade 25 cuts the environmentally friendly board. The waste will fall on the top of the workbench 1. Since multiple support bars 4 are set, the waste will fall between two adjacent support bars 4, which can reduce the number of times the waste is cleaned.

[0049] When workers need to clean up the waste on workbench 1, they first loosen the fastening bolts 55, then move the rectangular adjusting vertical plate 53 upwards until the strip positioning plate 54 moves above the scraper 30. At this point, workers tighten the fastening bolts 55 to fix the positions of the rectangular adjusting vertical plate 53 and the rectangular vertical tube 52, thereby suspending the strip positioning plate 54 and preventing it from obstructing the movement of the scraper 30. Then, workers rotate the rectangular push rod 32 upwards to a horizontal position so that the rectangular push rod 32 can pass through the rectangular hole 200. Then, workers push the rectangular push rod 32 forward, causing the rectangular push rod 32 to drive the rectangular connecting block 31 and the scraper 30 to move synchronously. The scraper 30 moves forward smoothly under the action of the two guide rods 41, scraping the waste on workbench 1 forward until the waste falls downwards from the strip chip discharge hole 10 and the strip clearance hole 11. The waste falls into the collection box 8 under the action of the first row of hoppers 6 and the second row of hoppers 7, making it convenient for workers to collect and process the waste.
