Description

Technical Field

[0001] The invention relates to the technical field of engraving machine auxiliary equipment, and in particular to a quick-connect dust removal cover for an engraving machine. Background Art

[0002] Engraving machines are widely used. They are usually used to cut various types of materials. Engraving machines cut by automatically controlling the cutter head, with high cutting efficiency and precision. However, the cutter head rotates at high speed during the cutting process, and a large amount of debris and dust will be generated during the cutting process. These debris and dust will be thrown out with the high-speed rotation of the cutter head, which will not only cause dust pollution to the working environment, but also the operator will easily inhale too much dust and affect their health. The debris falling on the engraving machine or the product will also affect the processing accuracy.

[0003] The existing engraving machine dust cover is sleeved on the engraving machine spindle. The debris and dust generated during the cutting process are blocked by the dust cover and the brush at the lower end of the dust cover. The suction pump is connected through the suction window on the dust cover to suck away the debris and dust. Although the existing technology solves the dust problem, it still has certain defects. For example, when the tool of the spindle needs to be replaced, the entire dust cover needs to be disassembled, which is inconvenient to operate, or the tool can be inserted into the dust cover through the movable window of the dust cover for replacement, but the space in the dust cover is too small, which greatly limits the range of manual activity and is also inconvenient to operate; in addition, the brush on the dust cover will be stuck with debris and needs to be cleaned frequently. The brush of the existing dust cover is usually integrated with the dust cover, and the entire dust cover needs to be disassembled for cleaning.

[0004] Therefore, a solution is needed to solve the above-mentioned defects. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a dust cover for an engraving machine, which can be quickly connected to the engraving machine and has the functions of easy disassembly and assembly and a simple cleaning method.

[0022] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0023] In this embodiment, if Figures 1 to 8 As shown, a quick-connect dust cover for an engraving machine includes an upper connecting plate 1, a lower connecting plate 2, a first suction piece 31 and a second suction piece 32, the upper connecting plate 1 is provided with a first connecting port 11 for fixing to the main shaft of the engraving machine and a first socket 12 for connecting to a dust suction pipeline, a first installation area 13 is provided at the bottom of the upper connecting plate 1, the first installation area 13 is fixedly connected to the first suction piece 31, a second installation area 23 corresponding to the first installation area 13 is provided at the top of the lower connecting plate 2, the second installation area 23 is fixedly connected to the second suction piece 32, and the upper connecting plate 1 and the lower connecting plate 2 are detachably and movably connected via the first suction piece 31 and the second suction piece 32.

[0024] Furthermore, the first attraction member 31 and the second attraction member 32 are strong magnets, and the upper connecting plate 1 and the lower connecting plate 2 are detachably connected through the suction force between the strong magnets.

[0025] Furthermore, the lower connecting plate 2 is provided with a second connecting port 21 for connecting to the main shaft of the engraving machine and a second socket 22 for connecting to the dust suction pipeline.

[0026] The first connection port is used to make the upper connection plate sleeved on the main shaft of the engraving machine, and the first socket is used to connect the ventilation duct, which is connected to the external suction device to absorb dust in the dust cover; using a strong magnet to connect the upper connection plate and the lower connection plate is convenient for disassembly and connection. When the lower connection plate needs to be removed, just hold the lower connection plate and pull it downward to separate the strong magnets. During installation, the second connection port and the second socket of the lower connection plate correspond to the first connection port and the first socket. The strong magnet in the first installation area is aligned with the strong magnet in the second installation area, and they are close and fit together. Under the action of magnetic attraction, the lower connection plate is connected to the upper connection plate.

[0027] In this embodiment, the upper connecting plate 1 is provided with an adjustment channel 14, one end of which is connected to the first connecting port 11, and the other end extends to the edge of the upper connecting plate 1, and the adjustment channel 14 is used to adjust the tightness of the connection between the first connecting port 11 and the engraving machine spindle.

[0028] Furthermore, the upper connecting plate 1 is provided with a T-shaped through hole 15 for placing a nut, and bolt holes are provided on both sides of the adjusting channel 14. The bolt holes on one side of the adjusting channel 14 are connected to the T-shaped through hole 15, and the bolt holes on the other side extend to the edge of the upper connecting plate 1.

[0029] It should be noted that the bolts are inserted from the edge of the upper connecting plate, and then pass through the bolt holes on both sides of the adjustment channel and extend into the T-shaped through hole. The head end of the bolt hole is stuck in the edge of the upper connecting plate, and the end of the bolt hole passes through the nut. The degree of connection between the bolt hole and the nut can adjust the width of the adjustment channel to adjust the tightness of the connection between the upper connecting plate and the main shaft.

[0030] In this embodiment, a brush 4 for blocking dust is connected to the periphery of the lower connecting plate 2. The brush 4 is made of nylon, which is low in cost and easy to clean.

[0031] The working principle of the above-mentioned quick-connect dust cover for engraving machines is:

[0032] Put the first connection port of the upper connection plate on the spindle of the engraving machine, use a nut to place it on the T-shaped through hole, insert the bolt from the edge of the upper connection plate, pass through the bolt holes on both sides of the adjustment channel, extend into the T-shaped through hole and connect with the nut, the operator tightens the bolt and nut with a tool, and fixes the upper connection plate to the spindle of the engraving machine; then, make the second connection port and the second socket on the lower connection plate correspond to the first connection port and the first socket of the upper connection plate, and the second installation area correspond to the first installation area, so that the strong magnets are opposite, drive the lower connection plate close to the upper connection plate, and the first connection hole of the lower connection plate passes through the spindle. Under suction, the lower connection plate is sucked onto the upper connection plate, and then the ventilation pipeline is connected to the suction device of the first socket, and the dust hood is installed.

[0033] When you need to replace the tool or clean the brush of the dust cover, just hold the lower connecting plate and pull it downward to separate the lower connecting plate from the upper connecting plate. The upper connecting plate is still fixed on the main shaft. At this time, you can easily replace the tool and clean the brush. After replacement or cleaning, move the upper connecting plate close to the lower connecting plate and reconnect it.

[0034] It can be seen that compared with the existing dust cover that cannot be disassembled and assembled upward or downward, the present invention uses a strong magnet to attract the upper and lower connecting plates, which makes disassembly and assembly simple and easy to operate, avoiding the tedious disassembly and assembly process when replacing the tool and cleaning the brush. The part connected to the main shaft is integrated with the dust cover, and the structure is more compact and firm.

[0035] For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the present invention.
