DETAILED DESCRIPTION

[0022] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-5 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0023] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] Embodiment 1, a noise reduction structure of an engraving machine, includes a mounting housing 1 and a cutting head 2, characterized in that:

[0025] The installation housing 1 is provided with an installation cavity 3 and a ventilation cavity 4, the installation housing 1 is provided with an air inlet duct 5 communicating with the ventilation cavity 4, an air outlet duct 6 communicating with the installation cavity 3, the installation cavity 3 is provided with a heat dissipation hole 7 communicating with the ventilation cavity 4, and a motor 8 is provided in the installation cavity 3;

[0026] The bottom of the installation housing 1 is detachably connected to a mounting plate 9, and a clamp 10 is rotatably connected to the mounting plate 9. The clamp 10 is driven by a motor 8, and a cutting knife 11 is provided on the clamp 10.

[0027] A sound insulation board is provided in the installation cavity 3;

[0028] An upper soundproof cover 12 is provided at the bottom of the mounting plate 9, a lower soundproof cover 13 is slidably connected to the upper soundproof cover 12, and a return spring 14 and a telescopic sleeve 15 are provided between the upper soundproof cover 12 and the lower soundproof cover 13;

[0029] The cutting knife 11 is located at the center of the upper soundproof cover 12;

[0030] A pressing plate 18 is provided at the bottom of the lower sound insulation cover 13 .

[0031] When in use, the cutting blade 11 is mounted on the fixture 10, and the motor 8 is started to drive the fixture 10 to rotate, thereby driving the cutting blade 11 to rotate;

[0032] During cutting, the motor 8 will generate most of the noise. Since the motor 8 is arranged in the installation cavity 3 and a sound insulation board is arranged inside, the noise is reduced under the effect of the sound insulation board. The motor 8 is sealed, which further increases the sound insulation effect.

[0033] To dissipate heat from the motor 8, the air inlet duct 5 and the air outlet duct 6 are connected to a heat dissipation system, and the fan in the heat dissipation system is started to realize air circulation, dissipate heat inside the installation cavity 3, and effectively protect the motor 8 components;

[0034] During cutting, huge noise will be generated between the cutting head 2 and the plate. Therefore, the mounting shell 1 will descend. During the descent, the pressure plate 18 will first contact with the placement plate of the cutting machine. As the mounting shell 1 descends, the cutting head 2 will contact with the plate. The pressure plate 18 and the lower sound insulation cover 13 will overcome the return spring 14 and shrink along the upper sound insulation cover 12. The motor 8 will be started and the cutting head 2 will start working. During cutting, the lower sound insulation cover 13 will contact with the placement plate of the cutting machine. Under the action of the upper sound insulation cover 12 and the lower sound insulation cover 13, the noise will be effectively reduced.

[0035] Embodiment 2, based on embodiment 1, the rotating end of the clamp 10 is provided with a card slot 16, and the output end of the motor 8 is provided with a card block 17 corresponding to the card slot 16;

[0036] The clamping slot 16 and the clamping block 17 are both arranged in a cross shape.

[0037] A card slot 16 is provided at the rotating end of the clamp 10, and a card block 17 corresponding to the card slot 16 is provided at the output end of the motor 8, and the card slot 16 and the card block 17 are both arranged in a cross shape, which is convenient for the installation of the mounting plate 9 and the installation between the clamp 10 and the motor 8;

[0038] Since the mounting shell 1 will perform mobile cutting on the X, Y, and Z axes, the friction between the mounting plate 9 and the placement table of the cutting machine is reduced when the X and Y axes move. The bottom of the mounting plate 9 is made of smooth material or a rolling wheel or rolling ball is provided at the bottom of the mounting plate 9.

[0039] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
