[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0029] Example:

[0030] A composite polishing and deburring device, see [link / reference] Figure 1The system includes an abrasive material conveying device, a dry ice conveying device, and a cleaning device. The abrasive material conveying device includes an abrasive material extractor 5, a pressurizing component, and a feeding pipe 37. The abrasive material extractor 5 extracts abrasive material and feeds it into the feeding pipe 37. The feeding pipe 37 is connected to the pressurizing component, which introduces compressed gas into the feeding pipe 37. The dry ice conveying device is connected to the feeding pipe 37. The cleaning device includes a cleaning platform 25, a lifting and rotating component, and a cleaning chamber 41. The cleaning platform 25 is installed inside the cleaning chamber 41 via the lifting and rotating component. The feeding pipe 37 communicates with the cleaning chamber 41 and is aligned with the workpiece on the cleaning platform 25. An abrasive material recovery auger 13 is located at the bottom of the cleaning chamber 41. The abrasive material recovery auger 13 is connected to the abrasive material extractor 5 via an abrasive material recovery pipe 9. The abrasive material recovery auger 13 is driven by an abrasive material recovery auger motor 15.

[0031] In this embodiment, the workpiece can be deburred multiple times using the abrasive material conveying device and the dry ice conveying device. Specifically, large burrs are removed first using the abrasive material, and then small burrs are removed and cleaned simultaneously using dry ice. At the same time, by placing the workpiece on the lifting platform, which reciprocates and rotates, all parts of the workpiece are flushed, making the deburring more thorough and efficient. Finally, the abrasive material is recycled, realizing its reuse and ensuring its cleanliness, eliminating the need for repeated cleaning, which is very environmentally friendly.

[0032] An abrasive hopper 4 is also provided between the abrasive material feeder 5 and the feeding pipe 37. A material control device 38 and a brush 39 are also provided at the connection between the abrasive hopper 4 and the feeding pipe 37. The material control device is a circular roller, driven by a material control device drive motor 35. By controlling its rotation speed, the amount of abrasive material entering the feeding pipe is controlled, thus allowing adjustment according to different workpiece specifications and different working conditions. The material control device uses a brush to prevent residual abrasive material.

[0033] The bottom of the cleaning chamber 41 is also equipped with a scrap metal recovery device. This device includes a scrap metal recovery box 11, a scrap metal extractor 10, a scrap metal recovery pipe 12, and a separation chamber 14 located below the abrasive material recovery auger 13. The separation chamber 14 collects the abrasive material separated from the abrasive material recovery auger 13. The separation chamber 14 is connected to the scrap metal extractor 10 via the scrap metal recovery pipe 12, and the scrap metal extractor 10 extracts the scrap metal from the separation chamber 14 and recovers it into the scrap metal recovery box 11. This design efficiently recovers scrap metal while also improving the cleanliness of the abrasive material.

[0034] The dry ice conveying device includes a dry ice chamber for storing block dry ice 33. One end of the block dry ice 33 is equipped with a dry ice crushing wheel 34, which is driven by a dry ice crushing motor 1 to crush the block dry ice to a suitable size. The other end is equipped with a dry ice pushing plate 31. The end of the dry ice chamber near the dry ice crushing wheel 34 is connected to a feeding pipe 37 via a dry ice pipe 36. The dry ice pushing plate 31 is used to push the block dry ice 33 toward the dry ice crushing wheel 34 and send the crushed dry ice into the feeding pipe 37. The lower part of the dry ice crushing wheel 34 is also connected to the feeding pipe 37 via a dry ice conveying auger 2, which is driven by a dry ice conveying auger motor 3. The dry ice pushing plate 31 is threadedly connected to a pushing plate drive screw 32, which is driven by a screw drive motor 30. With the above settings, the dry ice entering the feeding pipe is of a suitable size, suitable for processing different workpieces; and the dry ice is transported through the feeding pipe and pressurization components, without the need to add pipelines, thus saving costs.

[0035] The lifting and rotating assembly includes a base 16, a lifting rod 18, and a lifting drive motor 20. The base 16 is a hollow internally threaded sleeve base, and the lifting rod 18 is provided with a matching external thread for one end of the lifting rod 18 to be spirally mounted on the base 16. The base 16 is fixedly installed inside the cleaning chamber 41. One end of the lifting rod 18 is threadedly connected to the base 16, and the other end is connected to the cleaning platform 25. The lifting rod 18 is driven by the lifting drive motor 20.

[0036] The lifting drive motor 20 is connected to the drive gear 21. The lifting rod 18 is provided with a follower gear 22. The drive gear 21 meshes with the follower gear 22, which is used by the lifting drive motor 20 to drive the lifting rod 18 to rotate and lift within the base 16.

[0037] The composite polishing and deburring equipment in this embodiment also includes a lower limit relay 17 positioned above the cleaning platform 25 and an upper limit relay 23 positioned below it at a certain distance. The limit relays are also connected to the lifting drive motor 20. Through this arrangement, the limit relays are positioned at a certain distance above and below the follower gear, ensuring that the follower gear and the cleaning platform rotate and rise within the distance range of the limit relays. When the follower gear rises or falls to the position of the relay, the lifting drive motor is controlled to reverse, realizing the reciprocating rotation and lifting of the cleaning platform. In other embodiments, the relays can also be directly positioned at the upper and lower positions of the lifting platform.

[0038] The cleaning platform 25 is provided with a grid for discharging abrasive material and a limiting rod 26 for fixing the workpiece.

[0039] The feeding pipe 37 is also equipped with multiple nozzles, which are used to align the feeding pipe 37 with the workpiece from multiple different angles. In this embodiment, a lower nozzle 24, a left nozzle 27, a right nozzle 28, and an upper nozzle 29 are provided to scour the workpiece from all directions. The nozzles are connected to the feeding pipe via a feeding hose 19, which facilitates the adjustment of the nozzle position and angle.

[0040] The pressurization assembly includes a compression cylinder 6 and a compressor 7. One end of the compression cylinder 6 is connected to the compressor 7, and the other end is connected to the feeding pipe 37. A pneumatic oil-water separator 40 is also provided between the compression cylinder 6 and the feeding pipe 37. The compression cylinder 6 is connected to the compressor 7 through a compressed gas pipe and is used to store compressed gas. The pneumatic oil-water separator 40 is used to generate dry, oil-free compressed air and control its entry into the feeding pipe.

[0041] The working principle of the composite polishing and deburring equipment in this embodiment is as follows:

[0042] When the power is turned on, each part of the circuit performs a self-test. After the self-test is completed, the compressor 7 starts and generates compressed gas, which is stored in the compression cylinder 6. The compressed air passes through the pneumatic oil-water separator 40 to form dry, oil-free compressed air, which is then fed into the feeding pipe 37 as the driving gas.

[0043] The work is divided into two rounds:

[0044] (1) The abrasive material enters the abrasive hopper 4. The material control device 38 controls the amount of abrasive material entering the feeding pipe 37 by changing the speed of the drive motor 35, so as to achieve the cleaning power for cleaning different materials. The brush 39 ensures that the material control device 38 will not retain the abrasive material. At this time, the dry ice conveying auger motor 3 of the dry ice material conveying auger 2 stops moving, and the dry ice material cannot enter the pipe. Compressed air is used as power to drive the abrasive material to be sprayed out from the top, bottom and left and right nozzles for all-round first round of abrasion to remove large burrs.

[0045] (2) After the first round, the material control device drive motor 35 stops running, the abrasive material stops entering the pipe, and compressed air continues to spray for about 5 seconds to clean the residual abrasive material in the pipe. Then, the drive motor 30 drives the push plate transmission screw 32, thereby driving the dry ice push plate 31 to push the dry ice in the dry ice chamber closer to the dry ice crushing wheel 34, so that the dry ice material is processed into a size suitable for cleaning (preferably 1mm-2mm) and enters the dry ice conveying auger 2. The auger motor 3 drives the conveying to the dry ice pipe 36, and the compressed air is used as power to drive the dry ice to be sprayed out from the top, bottom and left and right nozzles for a second round of cleaning in all directions to remove the fine burrs on the surface and clean the residual abrasive material debris on the surface.

[0046] The transmission rod under the cleaning platform 25 consists of a follower gear 22 and a lifting rod 18. Powered by a lifting drive motor 20, the drive gear 21 drives the follower gear 22 to rotate at a constant speed (preferably 10-20 revolutions per minute). The lead screw meshes with the bottom base 16. Simultaneously, the forward and reverse rotation of the motor causes the cleaning platform and lifting rod to move up and down. When the motor rotates forward, the cleaning platform rises. When it touches the upper limit relay (preferably model KA123), the motor reverses, and the follower gear 22 begins to move downwards until the cleaning platform touches the lower limit relay (preferably model KA217). Then, the motor rotates forward again and begins to move upwards. The required cleaning range can be controlled by adjusting the distance between the two limit relays, adapting to the needs of workpieces of different heights.

[0047] After cleaning, the abrasive material enters the abrasive material recycling hopper and is collected and conveyed by the abrasive material recycling conveyor auger 13. Driven by the drive motor 15, it is transported to the bottom of the abrasive material recycling pipeline 9. An abrasive material extraction collector 5 is connected to the pipeline, so that the abrasive material flows back to the abrasive hopper 4, realizing the recycling of the abrasive material. During the operation of the auger, fine iron filings and abrasive material fragments are filtered out by a small screen and enter the separation chamber. They are then connected to an iron filings extraction machine 10 and uniformly extracted into the iron filings recycling chamber, realizing the recycling of pollutants.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
