Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a floating dust-collecting cutting machine. Background Technology

[0002] Cutting machines, as cutting devices, are widely used in industrial production. Commonly used cutting machines generate a large amount of dust during the removal of waste materials, causing environmental pollution and affecting the health of operators. Taking the cutting of wind turbine blades as an example: currently, after the blades are demolded, the cutting of the leading and trailing edges needs to be completed in a specially constructed dust-removal workshop, which must be installed in a specific location. During cutting, operators need to wear special dust-proof work clothes and safety dust hoods. The dust generated during cutting permeates the entire cutting workshop, which also requires multiple high-powered dust collection devices and numerous dust collection pipelines. Cutting workshops are expensive to build, have a long construction period, and only one-third of the dust produced during cutting can be absorbed by the dust collection equipment installed in the workshop; the remaining dust still needs to be manually removed, resulting in high workload and long time consumption.

[0003] To address this issue, Chinese patent CN 213469768 U discloses a dust-free cutting machine, comprising: a cutting assembly, an upper dust collection hood, a lower dust collection hood, and a connecting bridge plate. The cutting assembly includes a motor and a cutting blade. The motor is fixed to the outer side of the upper dust collection hood, and the cutting blade is rotatably connected inside the upper dust collection hood. A cutting opening is formed on the upper dust collection hood, with the cutting edge of the blade located outside the opening. An upper dust collection pipe is also connected to the upper dust collection hood, one end of which is connected to an external dust collection device. The lower dust collection hood has a suction port directly opposite the cutting opening, forming a cutting channel between the suction port and the cutting opening. A lower dust collection pipe is also connected to the lower dust collection hood, one end of which is connected to an external dust collection device. One end of the connecting bridge plate is fixed to the upper dust collection hood, and the other end is fixed to the lower dust collection hood. The connecting bridge plate is located at the outlet of the cutting channel, between the extended surfaces on both sides of the cutting blade. This device can effectively collect dust and prevent dust dispersion. However, this cutting machine requires manual adjustment of the cutting channel width. That is, after cutting a plate of one thickness and before cutting a plate of another thickness, it takes a long time to stop and adjust, which reduces the cutting efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a floating dust-collecting cutting machine to address the problem that the aforementioned cutting machines require manual adjustment of the cutting channel width, which takes a long time to stop and adjust to adapt to the thickness of the next cutting plate, thus reducing cutting efficiency.

[0038] Please see Figures 1 to 2 A floating dust-collecting cutting machine 100 according to one embodiment of the present invention includes a cutting driver 10, a fixed frame 20, a reducer 30, a cutting blade 40, a protective cover 50, and a floating mechanism 60. The fixed frame 20 is fixedly connected to the cutting driver 10, the reducer 30 is fixedly connected to the fixed frame 20, the reducer 30 is drivenly connected to the cutting driver 10, the cutting blade 40 is drivenly connected to the reducer 30, the protective cover 50 is connected to the fixed frame 20 through the floating mechanism 60, the protective cover 50 covers the cutting blade 40, the lower end of the protective cover 50 is provided with a cutting opening 51, and the side end of the protective cover 50 is provided with a dust collection port 52.

[0039] Please see Figures 1 to 3 The floating mechanism 60 includes a floating plate 61, a guide rod 62, and an elastic element 63. The floating plate 61 is connected to the fixed frame 20. The protective cover 50 is detachably connected to the floating plate 61. The floating plate 61 is provided with a guide hole 611. The output end of the reducer 30 passes through the guide hole 611 and is connected to the cutting blade 40 in a transmission manner.

[0040] Please see Figures 1 to 3The floating plate 61 is provided with an upper fixed seat 64 and two lower fixed seats 65, which are arranged opposite to each other. There are two upper fixed seats 64, which are spaced apart. One end of the guide rod 62 is fixedly connected to the upper fixed seat 64, and the other end of the guide rod 62 passes through the fixing frame 20 and is fixedly connected to the lower fixed seat 65. The elastic element 63 is fitted around the guide rod 62 and is located between the lower fixed seat 65 and the fixing frame 20. The elastic element 63, the guide rod 62, the lower fixed seat 65, and the upper fixed seat 64 correspond one-to-one. With the cooperation of the guide rod 62, the elastic element 63, and the guide sleeve 66, the floating plate 61 can move relative to the cutting blade 40 in a direction perpendicular to the axis of the cutting blade 40.

[0041] Please see Figure 3 The floating mechanism 60 further includes a guide sleeve 66, which includes a sleeve portion 661 and a limiting portion 662 connecting the sleeve portion 661. The sleeve portion 661 is fitted onto the guide rod 62. The fixing frame 20 has a through hole, and the sleeve portion 661 passes through the through hole. The limiting portion 662 is fixedly connected to the fixing frame 20. One end of the elastic member 63 abuts against the lower fixing seat 65, and the other end of the elastic member 63 abuts against the limiting portion 662. The guide sleeve 66 limits the maximum stroke of the floating plate 61 relative to the cutting blade 40.

[0042] Please see Figure 2 and Figure 5 The floating mechanism 60 further includes an abutment member 67, which is fixedly connected to the floating plate 61 and seals the lower ends of the floating plate 61 and the protective cover 50. The abutment member 67 is integrally connected to a limiting block 671. The floating plate 61 has a limiting groove, and the limiting block 671 is engaged in the limiting groove. The floating plate 61 has a fixing hole, and the limiting block 671 has a fixing screw hole 672 that matches the fixing hole. The abutment member 67 thus protects the floating plate 61 and the protective cover 50, effectively extending their service life.

[0043] Please see Figure 2 as well as Figure 4The floating vacuum cutting machine 100 also includes a locking mechanism 70, which is mounted on the floating plate 61.

The lock seat 71 is fixedly connected to the floating plate 61, the latching member 72 is hinged to the lock seat 71, and the locking ring 73 is hinged to the latching member 72. A locking block 53 is integrally connected to the protective cover 50, and the locking block 53 has a hook groove 54 that matches the locking ring 73. The locking mechanism 70 allows for a detachable connection between the floating plate 61 and the protective cover 50, facilitating disassembly and assembly by operators, making maintenance of the floating vacuum cutting machine 100 easier, shortening disassembly and assembly time, and improving maintenance efficiency.

[0044] The working principle of the floating dust-collecting cutting machine 100 in this embodiment is as follows: Before cutting, the dust collection port 52 is connected to the dust collection device through the air pipe; when the cutting blade 40 cuts downward, the floating plate 61 and the protective cover 50 move upward relative to the cutting blade 40 through the cooperation of the guide rod and the guide sleeve 66. When the cutting blade 40 moves upward, the floating plate 61 and the protective cover 50 return to their original position relative to the cutting blade 40 under the action of the elastic member 63. In this way, during the cutting process, the abutting member 67 is always in contact with the surface of the workpiece being cut, and the protective cover 50 is always covering the cutting blade 40, which effectively reduces the probability of cutting dust and effectively avoids dust emission, resulting in good dust collection effect.

[0045] The beneficial effects of this utility model are as follows: With the cooperation of the cutting driver 10, the fixing frame 20, the reducer 30, the cutting blade 40, the protective cover 50 and the floating mechanism 60, the protective cover 50 is always covered outside the cutting blade 40 during the cutting process, and the lower end of the protective cover 50 is always in contact with the wooden board, which effectively reduces the probability of cutting dust and debris being exposed, effectively prevents dust from being emitted, and has a good dust collection effect.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
