There are several problems with the waste discharge mechanism of the existing edge sawing machine: 1. The waste generated by cutting and the waste generated by product damage will be sucked into the fan, and the plastic fragments will also stick to the impeller, affecting the operation of the fan and causing the fan to burn. 2. The screws and loose parts on the equipment processed by the edge sawing machine may also be sucked into the fan, which will also cause damage to the fan. Summary of the invention

[0005] The utility model is provided with a filter barrel. When the waste is discharged under negative pressure, the waste enters the first chamber of the filter barrel from the suction port, and then enters the second chamber after being filtered by the filter component.

Detailed Embodiment

[0019] The following describes the details and working principles of the implementation mode and examples of the present invention in conjunction with the accompanying drawings. The waste discharge mechanism of this sawing machine includes a fan 1 and a filter barrel 2, and the filter barrel 2 is provided with a suction port 3 and an air outlet 4, and the air outlet 4 is connected to the fan 1 through a pipeline. The air outlet 4 is arranged above the suction port 3 and a filter component is arranged between the suction port 3 and the air outlet 4, and the filter component is arranged in the filter barrel 2 and divides the inner cavity of the filter barrel 2 into an unfiltered first cavity and a filtered second cavity 15. The utility model is provided with a filter barrel 2, and when the waste is discharged under negative pressure, the suction port 3 inhales air, and the airflow enters the first cavity of the filter barrel 2 from the suction port 3, and then enters the second cavity 15 after being filtered by the filter component. The waste is isolated in the first cavity by the filter component, thereby preventing the waste from entering the fan 1, thereby extending the service life of the fan 1.

[0020] The negative pressure airflow during waste discharge will stir the waste in the first cavity. When the waste in the first cavity increases, the waste will stay on the surface of the filter component, causing the filter channel to be blocked, resulting in insufficient negative pressure suction, affecting the waste discharge operation, and shortening the service life of the filter component. In order to ensure the waste discharge effect and extend the service life of the filter component, an anti-channeling cover 11 is provided below the suction port 3. The anti-channeling cover 11 divides the first cavity into a storage cavity 13 and an air intake cavity 10. The storage cavity 13 is below the air intake cavity 10, which is equivalent to the suction port 3 being set in the air intake cavity 10. The anti-channeling cover 11 isolates the airflow in the filter barrel 2 from the storage cavity 13 for waste collection, reduces the impact of the airflow on the storage cavity 13, keeps the filter component unobstructed, and the waste discharge operation proceeds smoothly, thereby extending the service life of the filter component. The anti-channeling cover 11 is funnel-shaped, and its outer edge is sealed with the filter barrel 2. A drop port 16 is provided in the center of the anti-channeling cover 11, that is, the drop port is at the lowest point of the anti-channeling cover. Waste materials falling on the anti-channeling cover will slide along the side wall of the anti-channeling cover to the lower drop port 16, and finally enter the storage cavity 13. The funnel shape is conducive to the waste materials to enter the storage cavity 13 downward, and can better block the airflow in the air inlet cavity 10 to prevent the airflow from entering the storage cavity 13.

[0021] The filter component includes a coarse filter 9 and a fine filter 14. The coarse filter 9 filters waste materials with large sizes, and the fine filter 14 filters waste debris with small particles. The coarse filter 9 is arranged below the fine filter 14. During negative pressure suction, the airflow passes through the air inlet chamber 10, the coarse filter 9, the fine filter 14 and the second chamber 15 in sequence. The coarse filter 9 is a stainless steel mesh plate, and the outer edge of the stainless steel mesh plate is sealed and installed with the filter barrel 2. The fine filter 14 includes a partition 5 and a filter element 6. There is a third chamber 8 between the partition 5 and the coarse filter 9. The filter element 6 is installed on the partition 5. The partition 5 is provided with a through hole that connects the central air outlet 7 of the filter element 6 with the second chamber 15. During negative pressure suction, the airflow passes through the third chamber 8 and the filter element 6 and then enters the second chamber 15 through the central air outlet 7 of the filter element 6.

[0022] The air outlet 4 is connected to the fan 1 through a pipeline; the fan 1 rotates forward to generate negative pressure to suck the material; the fan 1 rotates backward to blow air into the filter barrel 2, and the waste material in the filter barrel 2 is blown into the storage chamber 13. The fan 1 blows air, and the airflow blows the waste material on the surface of the filter component into the storage chamber 13, further extending the service life of the filter component. The filter barrel 2 is provided with a visual window 12, and the visual window 12 is set at the position of the storage chamber 13, so that the staff can timely see the amount of waste material in the storage chamber 13.

[0023] The working principle of the preferred embodiment is further described below in conjunction with the accompanying drawings: When the edge sawing machine is working, the fan 1 rotates forward to generate negative pressure suction, and the waste is sucked into the air inlet chamber 10. The larger waste is blocked by the stainless steel mesh disk, and the smaller waste passes through the mesh of the stainless steel mesh disk and enters the third chamber 8. The filter element 6 blocks the smaller waste to prevent it from entering the center of the filter element 6 and the air is discharged. After two layers of filtration, the waste is effectively filtered to prevent the waste from entering the fan 1. When the edge sawing machine stops working, the fan 1 blows air into the filter barrel 2 in the reverse direction, and the air flow passes through the pipeline, the second chamber 15, the filter element 6, the stainless steel mesh disk, and the air inlet chamber 10 in sequence, so that the waste stuck to the surface of the filter element 6 and the stainless steel mesh disk falls off, and the waste is blown into the storage chamber 13 from the drop-out port of the anti-channeling cover 11. The staff can understand the waste stock in the storage chamber 13 through the visual window 12, which is convenient for the staff to clean up the waste in the storage chamber 13.
