Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0032] A waste chip processing device for a numerically controlled lathe includes a processing box 1. Feeding ports 13 are symmetrically opened on both sides of the processing box 1. Support plates 2 are fixedly connected to the positions corresponding to the feeding ports 13 on both sides of the processing box 1, and a conveying device 3 is arranged on the support plates 2. A motor one 6 is fixedly connected to the front end face of the support plate 2 close to the processing box 1, and the motor one 6 is in transmission connection with the conveying device 3;

[0033] A filter cylinder 14 is rotatably connected inside the processing box 1. The top of the filter cylinder 14 is open, and a filter screen 16 is screwed to the bottom of the filter cylinder 14. A transmission shaft 21 is fixedly connected to the bottom of the filter screen 16. A motor two 17 is fixedly connected to the bottom of the processing box 1. The output shaft of the motor two 17 is fixedly connected to the transmission shaft 21. A drain pipe 8 is fixedly connected to the left side of the processing box 1 and communicated with the processing box 1. An extrusion plate 9 is arranged directly above the filter cylinder 14, and the outer diameter of the extrusion plate 9 is equal to the inner diameter of the filter cylinder 14.

[0034] Specifically, the conveying device 3 includes two groups of conveying rollers 11 rotatably connected to the support plates 2, and the conveying rollers 11 are symmetrically distributed on the support plates 2. A conveyor belt 10 is sleeved outside the conveying rollers 11. The output shaft of the motor one 6 is fixed to the front end of the conveying roller 11. One end of the conveyor belt 10 extends into the processing box 1 through the feeding port 13. The support plate 2 is designed at an inclined angle. A liquid discharge hole 12 is opened at a position close to the bottom end of the support plate 2 outside the processing box 1, and the liquid discharge hole 12 is designed at an inclined angle.

[0035] Specifically, an electric push rod 7 is fixedly connected to the top of the processing box 1, and the output shaft of the electric push rod 7 penetrates and extends into the interior of the processing box 1 and is fixedly connected to the center of the upper end surface of the extrusion plate 9.

[0036] By adopting the above technical solution, the electric push rod 7 is started to operate regularly according to the working week, driving the extrusion plate 9 to move downward and enter the filter cylinder 14 to extrude the waste chips in the filter cylinder 14, further accelerating the discharge of the liquid doped in the waste chips.

[0037] Specifically, a filter assembly 15 is arranged at a position below the filter cylinder 14 inside the processing box 1, and the filter assembly 15 is rotatably connected to the transmission shaft 21. A push-pull plate one 4 is movably connected to the front end face and the rear end face of the processing box 1, and the push-pull plate one 4 is fixed to the filter assembly 15. The filter assembly 15 includes a filter plate one 19 and a filter plate two 20 with the same size and structure. A rotation groove 23 for the rotation of the transmission shaft 21 is provided at the adjacent ends of the filter plate one 19 and the filter plate two 20. Groove openings are provided at positions on the inner wall of the processing box 1 corresponding to the filter plate one 19 and the filter plate two 20. One ends of the filter plate one 19 and the filter plate two 20 extend through the groove openings and are fixed to the pull plate one, and the filter plate one 19 and the filter plate two 20 are movably connected to the inner wall of the processing box 1 through the groove openings. The push-pull plate one 4 is magnetically fixed to the processing box 1.

[0038] By adopting the above technical solution, since the filter assembly 15 processes the liquid in the waste chips for a long time, it is inevitable that fine iron chips, dust, etc. will accumulate on the surface. Therefore, it is necessary to clean the filter assembly 15 regularly, otherwise it will block the filter assembly 15 and affect the operation of the filter plate one 19 and the filter plate two 20 in the filter assembly 15. Therefore, the user holds the push-pull plate one 4 and pulls the filter plate one 19 or the filter plate two 20 outward. The impurities accumulated on the upper end surface of the filter plate one 19 or the filter plate two 20 are continuously scraped and cleaned through the surface of the groove opening until the filter plate one 19 or the filter plate two 20 is completely pulled out, and the impurities fall into the aggregate box 22. The impurities on the lower end surfaces of the filter plate one 19 and the filter plate two 20 are scraped and cleaned by the scraping blade 24 and enter the aggregate box 22 to prevent the impurities from being taken out of the processing box 1. Then, the user pulls out the aggregate box 22 through the push-pull plate two 5, cleans the impurities inside the aggregate box 22, and then reinstalls the filter assembly 15 and the aggregate box 22.

[0039] Specifically, a guide plate 18 is fixed at the top opening of the filter cylinder 14 inside the processing box 1. The inner wall of the guide plate 18 is designed with an inclined angle corresponding to the top opening of the filter cylinder 14. The outer periphery of the guide plate 18 is rectangular and is fixed to the inner wall of the processing box 1. The inner wall of the guide plate 18 is distributed in an annular structure and fits the outer diameter of the filter cylinder 14.

[0040] By adopting the above technical solution, the waste chips fed into the processing box 1 enter the filter cylinder 14 under the action of the material guide plate 18 and are filtered through the filter screen 16 installed inside the filter cylinder 14.

[0041] Specifically, a second drag plate is magnetically fixed at the lower side of the filter assembly 15 on the left side of the processing box 1. An aggregate box 22 is arranged below the first filter plate 19 and the second filter plate 20. The aggregate box 22 penetrates through the processing box 1 and is movably connected to the processing box 1, and the aggregate box 22 is fixedly connected to the second drag plate. A scraping blade 24 with an inclined angle design is fixedly connected inside the aggregate box 22, and the top of the scraping blade 24 is in a fitting design with the lower end surfaces of the first filter plate 19 and the second filter plate 20.

[0042] Working principle: During operation, the conveying devices 3 on both sides of the device are connected to the waste chip collection chamber of the CNC lathe. The conveying devices 3 convey the waste chips generated by the CNC lathe into the interior of the treatment box 1. Mainly, the first motor 6 drives the conveying roller 11 to rotate, driving the conveyor belt 10 to rotate, and running the waste chips that fall on the conveyor belt 10. The waste chips are sent into the treatment box 1 through the feeding port 13. And during the process of the conveyor belt 10 conveying the waste chips, some of the liquid mixed in the waste chips will drip along the surface of the conveyor belt 10 into the interior of the support plate 2, and along the inclination angle of the inner wall of the support plate 2, it flows into the filter assembly 15 in the treatment box 1 through the drain hole 12. The filter assembly 15 filters the waste liquid. The waste chips sent into the treatment box 1 enter the filter cylinder 14 under the action of the guide plate 18 and are filtered through the filter screen 16 installed inside the filter cylinder 14. Then the liquid drips downward onto the filter assembly 15 for further filtration treatment. The filtered waste liquid is concentrated and precipitated in the waste liquid collection area inside the treatment box 1. Then the user regularly discharges the internal waste liquid into the designated equipment for recycling through the drain pipe 8. When the waste chips inside the filter cylinder 14 accumulate to a certain extent, or start the electric push rod 7 to run regularly according to the working cycle, driving the pressing plate 9 to move downward, entering the filter cylinder 14 to extrude the waste chips in the filter cylinder 14, further accelerating the discharge of the liquid mixed in the waste chips, and also being able to extrude the waste chips into blocks to ensure the storage capacity of the waste chips inside the filter cylinder 14. Since most of the waste chips processed by the CNC lathe are bent iron wires, they have tension, so they will occupy a large amount of internal storage space of the filter cylinder 14. Subsequently, start the second motor 17 to run, drive the filter cylinder 14 to rotate through the transmission shaft 21. The top of the transmission shaft 21 is fixed to the filter screen 16, so it can drive the filter cylinder 14 to rotate, performing high-speed centrifugal treatment on the iron chips inside to further accelerate the discharge of the waste liquid mixed in the iron chips. The filter screen 16 is actually a plate-shaped mesh structure with a certain extrusion strength. Since the filter assembly 15 processes the liquid in the waste chips for a long time, inevitably, fine iron chips, dust, etc. will accumulate on the surface. Therefore, it is necessary to clean the filter assembly 15 regularly, otherwise it will block the filter assembly 15 and affect the operation of the first filter plate 19 and the second filter plate 20 in the filter assembly 15. Therefore, the user holds the push-pull plate 1 and pulls the first filter plate 19 or the second filter plate 20 outward. The impurities accumulated on the upper end area of the first filter plate 19 or the second filter plate 20 are continuously scraped and cleaned through the surface of the notch until the first filter plate 19 or the second filter plate 20 is completely pulled out, and the impurities fall into the aggregate box 22. The impurities on the lower end surface of the first filter plate 19 and the second filter plate 20 are scraped and cleaned by the scraping blade 24 and enter the aggregate box 22 to prevent the impurities from being carried out of the treatment box 1. Then the user pulls out the aggregate box 22 through the push-pull plate 2, cleans the impurities inside the aggregate box 22, and then reinstalls the filter assembly 15 and the aggregate box 22.

[0043] The charged components in this application are controlled by an external controller to achieve automated control operation;

[0044] The top of the processing box 1 of this application is sealed with a screw-connected cover. Therefore, when a certain amount of iron filings accumulate inside the filter cartridge 14 or according to the working week, the user can open the sealed cover to centrally transport and process the iron filings collected inside the filter cartridge 14.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
