DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that the odorous gas generated in the existing cabinet door engraving machine during the engraving process is discharged through the isolation purification protection exhaust pipe structure at a fixed position, the fixed exhaust position has certain requirements for the placement of the equipment, and the odorous gas exhaust position cannot be flexibly adjusted according to the placement of the equipment, this embodiment provides the following technical solutions:

[0022] An engraving machine with multi-directional exhaust function comprises a lower shell 2, and a rotatable upper shell 1 is arranged on the upper end of the lower shell 2. Figure 1 As shown, the device to be engraved is placed inside the lower housing 2. After placement, the upper housing 1 is wrapped around the outside of the lower housing 2 by rotation to prevent the smoke generated during engraving from being discharged, providing a stable environment for the engraved object.

[0023] In this embodiment, side exhaust frames 4 are provided on both sides of the lower housing 2, a rear exhaust frame 3 is provided at one end of the lower housing 2, and an upper exhaust frame 5 is provided on one side of the upper end of the lower housing 2. Figure 1 and Figure 2 As shown, the gas generated by engraving in the lower housing 2 is discharged into the rear exhaust frame 3, the side exhaust frame 4 and the upper exhaust frame 5. The two side exhaust frames 4, the rear exhaust frame 3 and the upper exhaust frame 5 are an integrated structure. An air flow cavity 16 is provided inside the two side exhaust frames 4, the rear exhaust frame 3 and the upper exhaust frame 5. The gas is extracted by an external device and then transmitted to the inside of the air flow cavity 16.

[0024] In this embodiment, the middle position of one side of the side exhaust frame 4 is sealed and connected to the engraving position of the lower housing 2 through the first transmission pipe 6. Figure 2As shown, the lower end of the upper exhaust frame 5 is sealedly connected to the engraving position of the lower shell 2 through the second transmission pipe 7, and the gas generated by the engraving in the lower shell 2 can be transmitted to the connected air flow cavity 16 through the first transmission pipe 6 and the second transmission pipe 7 respectively;

[0025] In this embodiment, the four corners of the other side of the side exhaust frame 4, the four corners of one end of the rear exhaust frame 3 and both sides of the upper end of the upper exhaust frame 5 are provided with exhaust cavities 10 for exhausting. Figure 1 , Figure 2 and Figure 3 As shown, the air extraction cavity 10 passes through the corresponding rear exhaust frame 3, the side exhaust frame 4 and the upper exhaust frame 5 and extends to the internal air flow cavity 16. A fixing block 8 is provided at one end of the air extraction cavity 10. The fixing block 8 is located inside the air flow cavity 16. The fixing block 8 is respectively welded and fixed to the corresponding rear exhaust frame 3, the side exhaust frame 4 and the upper exhaust frame 5. The extended fixing block 8 can improve the sealing effect of the pipes subsequently inserted and connected. The outside of the air extraction cavity 10 is sealed with a filling block 9, and the outside of the filling block 9 is connected to the internal card slot of the air extraction cavity 10. The position where no exhaust is required is sealed by inserting the filling block 9 into the inside of the air extraction cavity 10 to achieve the sealing of the exhaust position;

[0026] In this embodiment, an extrusion block 11 is disposed around the interior of the fixed block 8, and a contraction cavity 12 is disposed at the position of the extrusion block 11 toward the fixed block 8. Figure 3 and Figure 4 As shown, the contraction cavity 12 is embedded in the fixing block 8, and the pipe inserted into the air extraction cavity 10 contacts the extrusion block 11. The extrusion of the extrusion block 11 can fix the pipe, and at the same time, it is convenient to improve the sealing degree of the pipe connected to the air extraction cavity 10.

[0027] In this embodiment, the side of the air extraction chamber 10 facing the lower shell 2 is provided with an inclined surface 14, and the side of the inclined surface 14 facing the lower shell 2 is provided with an anti-sliding block 15, and the anti-sliding block 15 is an integral structure with the extrusion block 11. Figure 4 and Figure 5 As shown, through the guidance of the anti-sliding block 15, when the pipeline is inserted into the exhaust chamber 10, the pipeline squeezes the extrusion block 11 and makes the extrusion block 11 fall into the contraction chamber 12. At the same time, as the pipeline continues to extend, the position of the anti-sliding block 15 continues to fit the outside of the pipeline. The pipeline is fixed by continuous fit. A return spring 13 is provided on the extrusion block 11 toward the inside of the contraction chamber 12. The two ends of the return spring 13 are fixedly connected to the extrusion block 11 and the contraction chamber 12 respectively. The return spring 13 can serve as a support for the extrusion block 11. At the same time, the return spring 13 can continuously push the extrusion block 11 and the filling block 9 due to its resilience, so as to continuously push and fix the pipeline.

[0028] Working principle: when using the device and engraving the engraving material, the engraving object is placed inside the lower shell 2, the upper shell 1 is rotated and wraps the upper end of the outer portion of the lower shell 2, and the transmission pipe used for exhaust is inserted into the exhaust chamber 10 according to the exhaust position. The pipe is inserted into the exhaust chamber 10 and contacts the inclined inclined surface 14. With the continuous push of the inclined inclined surface 14 and the pipe, the extrusion block 11 slides into the contraction chamber 12. As the pipe continues to be extended, the anti-sliding block 15 fits the pipe to complete the fixation of the pipe. At the same time, the resilience of the reset spring 13 makes the anti-sliding block 15 close to the filling block 9 to provide a sealing effect. The remaining position of the exhaust chamber 10 is inserted into the filling block 9 for filling.
