Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment, and in particular to a dust collection device with an air blower for a cutting machine. Background Technology

[0002] With the development of technology, wood processing centers are becoming increasingly common in the wood processing field. These centers can perform sawing, milling, vertical drilling, grooving, and other processes, making wood processing convenient and efficient. However, the processing generates a lot of dust and sawdust, resulting in a poor working environment, and this dust and sawdust also affects the surface quality of the workpiece. In particular, some dust from the cutting tools of the spindle machining unit adheres to the workpiece after processing, and / or the dust adheres to the cutting tools. Existing dust extraction technology for spindle machining units cannot remove this adhered dust.

[0003] Later, although some cutting machines on the market were equipped with air blowing devices to assist in dust collection, they had obvious defects. Traditional air blowing nozzles were mostly directly fixed and welded to the dust collection hood. This processing method easily caused the air blowing nozzle angle to deviate, making the air path skewed and unable to accurately blow towards the tool path position. Ineffective air blowing not only failed to assist in dust collection, but also blew the dust on the workpiece surface out of the effective range of the dust collection hood, further aggravating the pollution of the working environment. Some other air blowing nozzles adopted a nut-type disassembly and assembly structure, but the angle alignment was extremely difficult, and the adjustment process was cumbersome and complicated, bringing many inconveniences to actual operation and making it difficult to achieve the ideal dust collection assistance effect.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a dust collection device for a cutting machine with an air blowing frame that follows the air blowing. The device has several air blowing nozzles on a ring-shaped air blowing frame arranged at circumferential intervals, and the airflow direction is all towards the center of the cutting tool. In this way, the dust or particles generated in the cutting path can be accurately blown up before they are compressed and clump together during the cutting process. Combined with the dust collection effect of the dust collection hood, the dust collection efficiency is greatly improved, and the dust residue and diffusion are effectively reduced.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust collection device with an air blower for a panel saw includes an electric spindle, a dust collection hood, and a brush cover. A cutting tool is mounted on the electric spindle and located inside the dust collection hood. The dust collection hood is mounted on the electric spindle, with its suction port facing the cutting tool. The brush cover is mounted below the dust collection hood. A detachable annular air blower is provided between the dust collection hood and the brush cover.

[0008] The annular air blowing bracket is provided with a plurality of air blowing nozzles at circumferential intervals, and the airflow direction of the plurality of air blowing nozzles is all towards the center of the tool. The plurality of air blowing nozzles are made of brass.

[0009] As a preferred embodiment, a worktable for supporting the workpiece surface is also provided. The central axes of all the air nozzles intersect at the perpendicular intersection of the tool axis and the upper surface of the worktable. This further ensures that the airflow from all the air nozzles can be accurately focused on the central area of ​​the tool path, avoiding airflow dispersion or deviation from the tool path. This ensures that the dust or particles generated during cutting can be accurately blown up. Combined with the dust suction effect of the dust hood, it reduces the dust residue or diffusion on the board surface.

[0010] As a preferred embodiment, the angle between the central axis of the air nozzle and the upper surface of the worktable is 30°-60°. This angle range ensures that the airflow acts on the toolpath in a reasonable direction, avoiding the airflow from blowing obliquely outside the dust collection hood due to the angle being too small, while also preventing the angle from affecting the normal working space of the tool due to the angle being too large. This ensures that the airflow efficiently blows up the dust in the toolpath and enhances the dust collection efficiency of the dust collection pipe.

[0011] As a preferred embodiment, the vertical distance between the jet end of the plurality of air nozzles and the workpiece surface is 6mm-10mm. This can prevent the air nozzles from scratching the workpiece surface due to being too close, and can also prevent the airflow from weakening and failing to effectively blow up dust due to being too far away. This ensures the effectiveness of air blowing to assist in dust collection while guaranteeing processing quality.

[0012] As a preferred embodiment, the annular air blowing bracket is provided with an extension, and the air blowing pipe is mounted on the extension via a mounting component.

[0013] As a preferred embodiment, the air blowing pipe is welded to the extension via a mounting bracket.

[0014] As a preferred embodiment, the brush cover is also provided with a clearance hole, and the blowing end of the air nozzle passes through the clearance hole and is located inside the brush cover.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses several air nozzles on the annular air blowing bracket to be arranged at circumferential intervals, and the airflow direction is all towards the center of the tool. In this way, the dust or particles generated in the tool path can be accurately blown up before they are squeezed and condensed during the cutting process. Combined with the dust suction effect of the dust suction hood, the dust removal efficiency is greatly improved, and the dust residue and diffusion are effectively reduced.

[0016] Furthermore, the design of the ring-shaped air blowing bracket with air nozzles arranged circumferentially can adapt to the needs of different directions of cutting. With the synergistic effect of the dust collection hood and the brush hood, it can achieve all-round air blowing and dust collection function without affecting the normal operation of the tool, thus improving the dust-free level of the cutting operation.

[0017] Secondly, the air nozzle is made of brass, which is relatively soft. If the angle is found to be skewed during assembly, it can be easily corrected with simple tools (such as wire cutters). This solves the problem of difficult adjustment of angle deviation in traditional fixed welding structures, ensuring that the air is always accurately applied to the target area.

[0018] Furthermore, the ring-shaped air blowing bracket is detachably installed between the dust suction hood and the brush hood. As an independent component, it can be disassembled and replaced at any time, making operation simple and quick, reducing the difficulty and time cost of equipment maintenance, and facilitating later maintenance.

[0035] A dust collection device for a cutting machine with an air blowing frame and air following the blowing, including an electric spindle 1, a dust collection hood 2, and a brush hood 3.

[0036] A cutting tool 11 is mounted on the electric spindle 1, and the cutting tool 11 is located inside the dust collection hood 2; the dust collection hood 2 is mounted on the electric spindle 1, and the dust collection port of the dust collection hood 2 is positioned facing the cutting tool 11; the brush cover 3 is mounted below the dust collection hood 2;

[0037] A ring-shaped air blowing bracket 4 is detachably provided between the dust suction hood 2 and the brush cover 3. Several air blowing nozzles 5 are arranged at circumferential intervals on the ring-shaped air blowing bracket 4. The airflow direction of the several air blowing nozzles 5 is all towards the center of the cutter 11. The several air blowing nozzles 5 are made of brass.

[0038] In this embodiment, the air inlet of the air nozzle 5 is connected to the input air pipe (not shown in the figure). Since the mounting part 42 is through-connected, it is connected to the air inlet of the air nozzle 5 through an additional air pipe.

[0039] Preferably, the annular air-blowing bracket 4 is provided with an extension portion 41, and the air-blowing pipe is mounted on the extension portion 41 via a mounting member 42. Preferably, the air-blowing pipe is welded to the extension portion 41 via the mounting member 42.

[0040] Preferably, the vertical distance between the air jet end of the plurality of air nozzles 5 and the workpiece plate surface 61 is 6mm-10mm. This avoids the air nozzles 5 scratching the workpiece plate surface 61 due to excessively close distance, and also prevents the airflow from weakening and failing to effectively blow away dust due to excessive distance. This ensures the effectiveness of air-assisted dust collection while guaranteeing processing quality. Preferably, the brush cover 3 is also provided with a clearance hole 31, through which the air jet end of the air nozzle 5 passes and is located inside the brush cover 3.

[0041] Preferably, a worktable 6 for supporting the workpiece plate 61 is also provided. The central axes of the air nozzles 5 all intersect at the vertical intersection point of the axis of the tool 11 and the upper surface of the worktable 6. This further ensures that the airflow of all the air nozzles 5 can be accurately focused on the central area of ​​the tool path, which can avoid the airflow from being dispersed or deviating from the tool path. This ensures that the dust or particles generated during the cutting process can be accurately blown up. Combined with the dust suction effect of the dust suction hood 2, it reduces the dust residue or diffusion on the plate surface.

[0042] Preferably, the angle between the central axis of the air nozzle 5 and the upper surface of the worktable 6 is 30°-60°. This angle range can ensure that the airflow acts on the tool path in a reasonable direction, avoiding the airflow from blowing obliquely to the outside of the dust collection hood 2 due to the angle being too small, and can also prevent the angle from affecting the normal working space of the tool 11 due to the angle being too large, ensuring that the airflow efficiently blows up the dust in the tool path and enhances the dust collection efficiency of the dust collection pipe.

[0043] The dust collection hood 2 forms a negative pressure airflow from top to bottom. The airflow direction is vertically upward from the bottom opening of the dust collection hood 2, and is discharged through the dust collection pipe. The air nozzle 5 blows the dust along the blade path upward at an angle (the blowing direction is at a 30° to 60° angle to the plate surface and points towards the center of the blade 11). The upward suction force of the dust collection hood 2 and the blowing direction form a combined force, causing the dust to rise along a spiral trajectory, preventing dust from overflowing. The bottom opening diameter of the dust collection hood 2 is larger than the cutting range of the blade 11, ensuring that all the dust blown by the air nozzle 5 covers the dust collection range. The brush cover 3 blocks external airflow interference and enhances the negative pressure adsorption efficiency.

[0044] The key design feature of this utility model is that it mainly uses several air nozzles on the annular air blowing bracket to be arranged at circumferential intervals, and the airflow direction is all towards the center of the tool. In this way, the dust or particles generated in the tool path can be accurately blown up before they are squeezed and clumped during the cutting process. Combined with the dust suction effect of the dust suction hood, the dust removal efficiency is greatly improved, and the dust residue and diffusion are effectively reduced.

[0045] Furthermore, the design of the ring-shaped air blowing bracket with air nozzles arranged circumferentially can adapt to the needs of different directions of cutting. With the synergistic effect of the dust collection hood and the brush hood, it can achieve all-round air blowing and dust collection function without affecting the normal operation of the tool, thus improving the dust-free level of the cutting operation.

[0046] Secondly, the air nozzle is made of brass, which is relatively soft. If the angle is found to be skewed during assembly, it can be easily corrected with simple tools (such as wire cutters). This solves the problem of difficult adjustment of angle deviation in traditional fixed welding structures, ensuring that the air is always accurately applied to the target area.

[0047] Furthermore, the ring-shaped air blowing bracket is detachably installed between the dust suction hood and the brush hood. As an independent component, it can be disassembled and replaced at any time, making operation simple and quick, reducing the difficulty and time cost of equipment maintenance, and facilitating later maintenance.

[0048] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
