Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machining, and more particularly to a waste material recovery device for a numerical control machining center. Background Art

[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for processing complex parts. It is currently one of the world's most productive and widely used CNC machine tools. It has a strong comprehensive processing capability, can complete more processing content after the workpiece is clamped once, and has high processing precision. For batch workpieces with medium processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment. In particular, it can complete processing that many ordinary equipment cannot complete, and is more suitable for single-piece processing with complex shapes and high precision requirements, or small and medium-sized batch and multi-variety production. It concentrates milling, boring, drilling, tapping and thread cutting functions on one device, giving it a variety of process means. Machining centers are classified according to the spatial position of the spindle during processing: horizontal and vertical machining centers.

[0003] When the CNC machining center processes workpieces of different materials, the material of the waste generated will also be different.

[0004] However, the existing waste recycling devices of CNC machining centers usually recycle all waste materials, that is, the different waste materials generated when the CNC center processes workpieces of different materials. In the recycling process, it is necessary to distinguish the waste materials of various materials. Since the CNC center generates relatively small waste materials during the processing, the difficulty of waste recycling is increased. Summary of the Invention

[0063] At least two through holes 10 are provided on the circular rotating plate 3 , the number of the through holes 10 is consistent with the number of the feed boxes 4 , and the outer side wall of the feed box 4 is fixedly connected to the side wall of the through hole 10 , and the lower end of the feed box 4 passes through the through hole 10 and is located on the lower side of the circular rotating plate 3 .

[0064] The crushing assembly includes two rotating shafts 11, and the two rotating shafts 11 are symmetrically arranged. The ends of the rotating shafts 11 are rotatably connected to the inner wall of the feed box 4, and one end of the rotating shaft 11 passes through the side wall of the feed box 4 and is located on the outside of the feed box 4.

[0065] The crushing roller 12 is fixedly connected to the rotating shaft 11, and the outer peripheral wall of the crushing roller 12 is fixedly connected with crushing teeth 13. There are multiple groups of crushing teeth 13, and the multiple groups of crushing teeth 13 are horizontally distributed. The multiple crushing teeth 13 in each group are annularly distributed on the circumferential wall of the crushing roller 12. A fixed plate 40 is fixedly connected to the inner side wall of the feed box 4, and multiple limiting rods 41 are fixedly connected to the side wall of the fixed plate 40. The limiting rod 41 is tilted and located between two adjacent groups of crushing teeth 13. The limiting rod 41 is used to limit the waste stuck on the crushing teeth 13 to rotate as the crushing teeth 13 rotates, thereby realizing the cleaning of the waste stuck on the crushing teeth 13, and a cleaning brush 42 is fixedly connected to the inner side wall of the feed box 4. The bristles on the cleaning brush 42 are in contact with the circumferential wall of the crushing roller 12, so that the cleaning brush 42 can clean the waste remaining on the crushing roller 12.

[0066] The drive motor 14 is fixedly connected to the outer wall of the collection box 1. The output shaft of the drive motor 14 passes through the side wall of the collection box 1 and is fixedly connected to the first gear 15. The second gear 16 is fixedly connected to the rotating shaft 11, and the second gear 16 is meshed with the first gear 15.

[0067] The interior of the rotating shaft 11 is hollow. A water pipe 17 is inserted into the rotating shaft 11 . One end of the water pipe 17 extends to the outside of the rotating shaft 11 .

[0068] A connecting pipe 18 is fixedly connected to the outer wall of the collection box 1, and the connecting pipe 18 cooperates with the end of the water pipe 17. One end of the connecting pipe 18 does not pass through the side wall of the collection box 1 and is connected to the water delivery equipment in the prior art, such as a faucet, so as to facilitate the delivery of water to the water pipe 17 through the connecting pipe 18. A sealing gasket is fixedly connected to the surface of the connecting pipe 18, and the sealing gasket is in contact with the end of the water pipe 17, so as to increase the sealing between the water pipe 17 and the connecting pipe 18.

[0069] The water pipe 17 is located at one end of the rotating shaft 11 and its top is open, and a water outlet 19 is provided on the rotating shaft 11 and the crushing roller 12. The water outlet 19 is located between two adjacent crushing teeth 13. The water outlet 19 is used to spray the water transported by the water pipe 17 to the outside. Since the top of the water pipe 17 is located at one end of the rotating shaft 11 and its top is open, that is, the water pipe 17 is located at one end of the rotating shaft 11 and is an arc-shaped plate, and the bottom of the water pipe 17 is in contact with the inner wall of the rotating shaft 11, the water transported by the water pipe 17 is sprayed through the water outlet 19 on the top of the rotating shaft 11 and the crushing roller 12, thereby facilitating the spraying of water on the waste material that slides on the crushing roller 12, increasing the humidity of the waste material that slides on the crushing roller 12, and avoiding the crushing roller 12 from generating dust during the process of crushing the waste material.

[0070] A support rod 20 is fixedly connected to the inner wall of the feed box 4, and a heating resistance wire 21 is fixedly connected to the support rod 20. A fixed protective cover 22 is provided on one side of the heating resistance wire 21. The fixed protective cover 22 is fixedly connected to the inner wall of the feed box 4. When the waste contains too much moisture, the heating resistance wire 21 heats the crushing roller 12, so that the heat on the crushing roller 12 is transferred to the waste, thereby heating the waste and facilitating the evaporation of moisture in the waste.

[0071] A rotating protective cover 23 is provided on the other side of the heating resistance wire 21. The rotating protective cover 23 is arranged opposite to the fixed protective cover 22. Both the rotating protective cover 23 and the fixed protective cover 22 are arc-shaped. The outer arc wall diameter of the rotating protective cover 23 is equal to the inner arc wall diameter of the fixed protective cover 22.

[0072] The end of the rotating protective cover 23 is fixedly connected to a connecting tube 24 , and the connecting tube 24 is sleeved on the support rod 20 .

[0074] A circular through hole 26 is provided on the side wall of the feed box 4 for the connecting tube 24 to pass through. The end of the support rod 20 passes through the circular through hole 26 and is fixedly connected to the support plate 25. One end of the connecting tube 24 passes through the circular through hole 26 and is rotatably connected to the support plate 25. The support plate 25 is used to support the diameter of the support rod 20.

[0075] A symmetrically arranged second servo motor 27 is fixedly connected to the outer wall of the feed box 4, and a sprocket 28 is fixedly connected to the output shaft of the second servo motor 27 and the connecting cylinder 24, and a chain 29 is sleeved on the sprocket 28. The second servo motor 27 is used to control the forward and reverse rotation of the rotating protective cover 23. When the second servo motor 27 drives the rotating protective cover 23 to rotate 180° in the forward direction through the cooperation of the sprocket 28 and the chain 29, the rotating protective cover 23 and the fixed protective cover 22 are overlapped, and the heat on the heating resistance wire 21 is dissipated to the outside through the sides of the rotating protective cover 23 and the fixed protective cover 22. When the heating resistance wire 21 is not needed, the second servo motor 27 drives the rotating protective cover 23 to rotate 180° in the opposite direction through the cooperation of the sprocket 28 and the chain 29. At this time, the side wall of the rotating protective cover 23 and the side wall of the fixed protective cover 22 are in the same plane, that is, a cylindrical shape is formed between the rotating protective cover 23 and the fixed protective cover 22, thereby preventing dust or water from contacting the heating resistance wire 21.

[0076] The top of the collecting barrel 5 is covered with a cover plate 30 , which is fixedly connected to the inner wall of the collecting box 1 , and a telescopic hose 31 is fixedly connected to the upper surface of the cover plate 30 .

[0077] The bottom of the feed box 4 is fixedly connected to a discharge funnel 32 , and the upper end of the telescopic hose 31 is fixedly connected to the bottom of the discharge funnel 32 .

[0078] A rectangular through hole 33 for the collecting barrel 5 to pass through is provided on the side wall of the collecting box 1 , and the width of the rectangular through hole 33 is consistent with the diameter of the outer ring wall of the collecting barrel 5 .

[0079] A filter screen 34 is fixedly connected to the inner side wall of the collecting barrel 5 . The filter screen 34 is tilted, and a discharge port 35 is opened on the side wall of the collecting barrel 5 . The discharge port 35 is located at the lower side of the filter screen 34 .

[0080] A second rotating rod 36 is rotatably connected to the inner wall of the collecting box 1, and a strike hammer 37 is fixedly connected to the second rotating rod 36. The strike hammer 37 contacts the outer wall of the collecting funnel 2. A limiting plate 39 is fixedly connected to the second rotating rod 36. A push rod 38 is fixedly connected to the output shaft of the driving motor 14. The push rod 38 cooperates with the limiting plate 39. A torsion spring is sleeved on the second rotating rod 36. One end of the torsion spring is fixedly connected to the inner wall of the collecting box 1, and the other end of the torsion spring is fixedly connected to the second rotating rod 36. When the torsion spring is in a natural state, the strike hammer 37 contacts the outer wall of the collecting funnel 2.

[0081] Working principle: The collection box 1 is fixed directly below the CNC machining center's CNC machining center. When the CNC machining center in the CNC machining center processes the waste materials generated by the waste materials, the waste materials slide down into the collection hopper 2 and slide down into the feed box 4 through the lower port of the collection hopper 2. The drive motor 14 is started, and the output shaft of the drive motor 14 drives the first gear 15 to rotate. During the rotation of the first gear 15, the first gear 15 drives the second gear 16 meshing with it to rotate. Since there are two drive motors 14, the drive motor 14 drives the crushing rollers 12 to rotate through the cooperation of the first gear 15 and the second gear 16, so that the two crushing rollers 12 rotate in opposite directions, and at the same time drive the push rod 38 to rotate. When the push rod 38 contacts the limit plate 39, the push rod 38 pushes the limit plate 39 upward, so that the second rotating rod 36 drives the impact hammer 37 to rotate in the direction away from the collection funnel 2. When the push rod 38 disengages from the limit plate 39, due to the rotation of the torsion spring The rotating force causes the second rotating rod 36 to drive the impact hammer 37 to rotate in the direction of the collecting funnel 2, so that the impact hammer 37 hits the outer wall of the collecting funnel 2, causing the side wall of the collecting funnel 2 to vibrate, and shaking off the fine waste remaining on the inner wall of the collecting funnel 2, thereby reducing the fine waste remaining on the inner wall of the collecting funnel 2. In the process of the two crushing rollers 12 rotating towards each other, the waste falling on the crushing rollers 12 is crushed and crushed, and the crushed waste slides downward through the discharge funnel 32 and the telescopic hose 31 into the collection bucket 5, and the finer waste particles slide down through the holes on the filter screen 34 to the bottom of the collection bucket 5. At this time, the staff can place the collection container for collecting larger particles of waste outside the collection box 1 and directly below the discharge port 35, and the larger particles of waste roll downward through the inclined surface of the filter screen 34 into the collection container outside the collection box 1, thereby realizing the separation of smaller particles in the waste and distinguishing and collecting large and small particles of waste.

[0082] During the process of the crushing teeth 13 on the crushing roller 12 crushing the waste, when the waste is stuck on the crushing teeth 13, and the crushing roller 12 drives the crushing teeth 13 with the waste stuck to rotate to the end of the limiting rod 41, since the end of the limiting rod 41 is in contact with the circumferential wall of the crushing roller 12, and the end of the limiting rod 41 is conical, the waste stuck on the crushing teeth 13 is restricted by the small end of the limiting rod 41 to rotate with the crushing roller 12, thereby realizing the cleaning of the waste stuck on the crushing teeth 13 and between two adjacent crushing teeth 13.

[0083] A detector is fixedly connected to the inner wall of the collecting funnel 2. The detector is used to detect the material of the waste, and the detector is electrically connected to the first servo motor 6 through a signal. When the detector detects that the collected waste is waste of the second material, the detector transmits the information to the first servo motor 6. The first servo motor 6 drives the circular rotating plate 3 to rotate through the first rotating rod 7, and at the same time drives multiple feed boxes 4 to rotate, so that the second feed box 4 rotates to the bottom of the lower port of the collecting funnel 2, and the upper port of the feed box 4 is opposite to the lower port of the collecting funnel 2. At this time, the second gear 16 on the second feed box 4 is engaged with the first gear 15, and the collected second material slides down through the collecting funnel 2 into the second feed box 4. At the same time, the driving motor 14 is engaged with the second gear 16 on the second feed box 4 through the first gear 15, driving the crushing roller 12 in the second feed box 4 to rotate, so as to facilitate the crushing of the collected second waste, thereby realizing the differentiated collection of wastes of different materials, avoiding the mixing of multiple wastes, and reducing the difficulty of processing and collecting multiple wastes.

[0084] When the detector detects that the material of the waste collected in the collecting funnel 2 is the same as the waste collected in the first feed box 4, the detector transmits the information to the first servo motor 6, and the first servo motor 6 drives the circular rotating plate 3 to rotate in the opposite direction through the first rotating rod 7, so that the first feed box 4 rotates to the bottom of the lower port of the collecting funnel 2, so as to facilitate the collection of waste of the same material in the same collection bucket 5.

[0085] When the waste collected in the collecting funnel 2 is relatively dry and generates a large amount of dust during crushing, such as when ceramic material or stone waste is crushed, the water supply system connected to the connecting pipe 18, such as a faucet, is turned on at this time, so that water is transported to the rotating shaft 11 through the connecting pipe 18 and the end of the water supply pipe 17 in contact therewith, and is sprayed out through the water outlet 19 on the rotating shaft 11 and the top of the crushing roller 12, thereby spraying the water on the waste located on the crushing roller 12. At the same time, the water falls downward on the crushing teeth 13 on the upper side of the crushing roller 12 due to the action of gravity. When the crushing teeth 13 with water attached on the two crushing rollers 12 mesh with each other and crush the waste, the tip of the crushing teeth 13 is inserted into the waste for crushing. The waste will absorb the water attached to the crushing teeth 13, thereby increasing the humidity inside the waste. After the waste is crushed, the dust generated by the waste crushing can be reduced, thereby achieving the purpose of dust reduction.

[0086] When the waste collected in the collecting funnel 2 is metal waste with a high degree of moisture, such as iron waste, the staff closes the water supply system connected to the connecting pipe 18, such as a faucet, and turns on the second servo motor 27. The output shaft of the second servo motor 27 drives the rotating protective cover 23 to rotate 180 degrees in the forward direction through the cooperation of the sprocket 28 and the chain 29, so that the rotating protective cover 23 overlaps with the fixed protective cover 22, that is, the end face of the rotating protective cover 23 is flush with the end face of the fixed protective cover 22. When the heating resistance wire 21 is turned on, the heating resistance wire 21 diffuses the heat to the outside through the open ends of the rotating protective cover 23 and the fixed protective cover 22, thereby facilitating heating. The thermal resistance wire 21 heats the crushing roller 12 and the crushing teeth 13, and the crushing roller 12 and the crushing teeth 13 transfer heat to the metal scrap, thereby increasing the temperature of the metal scrap and facilitating the evaporation of moisture on the metal scrap, thereby achieving the purpose of reducing the moisture on the surface of the metal scrap. In the process of the crushing teeth 13 crushing the metal scrap, since the tip of the crushing teeth 13 is inserted into the metal scrap for crushing, the temperature on the crushing teeth 13 is transferred to the inside of the metal scrap, thereby heating the inside of the metal scrap, further promoting the evaporation of moisture attached to the metal scrap, thereby reducing the rust area of the metal and facilitating the recycling of the metal scrap.
