Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, specifically a waste recycling mechanism for CNC machining center machine tools. Background Technology

[0002] A CNC machining center is a highly automated CNC machine tool that integrates multiple functions and can perform various types of machining operations. Its characteristics include high precision and efficiency, multi-functionality, high automation, high rigidity, and stability. CNC machining centers can achieve continuous machining of multiple processes and surfaces, significantly improving production efficiency and machining accuracy. During the machining process, some waste material is generated. To prevent this waste from affecting the machine tool, it needs to be cleaned up and recycled.

[0003] Chinese Patent Publication No. CN219649347U describes a waste recycling mechanism for CNC machining centers. A stepper motor drives a rotating rod, which in turn rotates a second bevel gear, causing a lead screw to rotate. This causes a scraper to move horizontally left and right, pushing iron filings into the feed troughs on both sides. The iron filings fall from the feed troughs into a funnel and then into a compression chamber. Next, a cylinder drives a pressure plate, which engages with the inside of the chamber door to compress the iron filings into blocks. Finally, the chamber door is opened, and the iron filing blocks are pushed out through the cylinder output. Because the compressed iron filings are very heavy, this method eliminates the need for manual handling, saving labor and meeting the needs of workers.

[0004] While the aforementioned patent can automatically recycle waste generated during CNC machine tool processing, the machine tool uses coolant or cutting fluid during the processing, but the aforementioned patent cannot filter and recycle the coolant or cutting fluid. Utility Model Content

[0005] The purpose of this utility model is to provide a waste recycling mechanism for CNC machining centers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waste recycling mechanism for a CNC machining center includes:

[0008] A CNC machine tool body is set on the ground for processing workpieces. The top surface of the operating table of the CNC machine tool body has a groove. A limit frame is fixedly connected inside the groove. An insertion hole is opened through the side of the CNC machine tool body above the limit frame. A liquid outlet pipe is fixedly connected through the bottom end of one inner side of the groove.

[0009] A conveying mechanism, which runs through the bottom of the groove, is used to remove and recycle waste generated during workpiece processing from the groove.

[0010] A filter mechanism, located inside the groove, is used to filter out waste chips from the cutting fluid or coolant. The filter mechanism includes a filter plate that is slidably inserted into the insertion hole and abuts against the top surface of the limiting frame. A connecting plate is fixedly connected to one side of the filter plate. Limiting components for limiting the filter plate are provided on the side of the CNC machine tool body and at both ends of the connecting plate.

[0011] Furthermore, both ends of the side of the connecting plate are provided with circular grooves, and the limiting member includes:

[0012] The slide bar is fixedly connected to the side of the CNC machine tool body;

[0013] The skateboard runs through the outer wall of the sliding bar at the corresponding position;

[0014] The insert block is fixedly connected to the bottom side of the slide plate at the corresponding position and is inserted into the circular groove at the corresponding position.

[0015] Furthermore, a stop block is fixedly connected to one end of the slide rod, and a spring is provided between the stop block and the slide plate at the corresponding position.

[0016] Furthermore, a rubber pad is fixedly connected to one side of the connecting plate that connects to the filter plate, and the length and width of the connecting plate are both greater than the length and width of the insertion hole.

[0017] Furthermore, the CNC machine tool body has rectangular holes penetrating its two opposite sides, communicating with the interior of the groove; fixed blocks are fixedly connected to the back of the CNC machine tool body at both ends of the rectangular holes; the conveying mechanism includes:

[0018] Two symmetrical circular rollers, one of which is rotatably connected between the two ends inside a rectangular hole on the front of the CNC machine tool body, and the other is rotatably connected between two fixed blocks;

[0019] A conveyor belt, fitted between two circular rollers, has a mesh structure.

[0020] Furthermore, one end of a circular roller located on the back of the CNC machine tool body passes through a fixed block at a corresponding position and is fixedly connected to a pulley. A circular rod is rotatably connected between the two fixed blocks. A brush roller that contacts the conveyor belt is fixedly connected to the outer wall of the circular rod. One end of the circular rod passes through a fixed block at a corresponding position and is fixedly connected to a pulley, which is connected to the pulley via a belt drive. A motor is fixedly connected to the back of the CNC machine tool body, and the output end of the motor is fixedly connected to the circular rod.

[0021] Furthermore, the diameter of the first pulley is larger than the diameter of the second pulley.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. Through the action of the filter plate, fine waste chips mixed with cutting fluid or coolant can be filtered out, so that the cutting fluid or coolant can be recycled and the waste generated during workpiece processing can be completely recovered.

[0024] 2. By inserting the filter plate into the groove, then rotating the two slide plates and compressing the two springs, the insertion block is aligned with the corresponding circular groove. Then, the slide plates are moved so that the insertion block is inserted into the corresponding circular groove. Due to the elasticity of the two springs, the filter plate can be prevented from shifting position.

[0025] 3. Driven by a motor, the conveyor belt can roll between two rollers. Since the surface of the conveyor belt has a mesh structure, it is easy for cutting fluid or coolant to pass through the conveyor belt. The rolling conveyor belt can remove some larger waste materials from the groove, and the rotating brush roller can clean some small waste materials adsorbed on the surface of the conveyor belt, thereby preventing them from mixing with the small waste materials generated during the next processing of other metal workpieces.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-6 In this embodiment of the present invention, a waste recycling mechanism for a CNC machining center includes a CNC machine tool body 1, a conveying mechanism 2, and a filtering mechanism 3. The CNC machine tool body 1 is set on the ground and is used for machining workpieces. A groove is formed on the top surface of the operating table of the CNC machine tool body 1. A limit frame 11 is fixedly connected inside the groove. An insertion hole 12 is formed through the side of the CNC machine tool body 1 above the limit frame 11. A liquid outlet pipe 15 is fixedly connected through the bottom end of one inner side of the groove. The conveying mechanism 2 is set through the bottom end of the groove and is used to remove and recycle the waste generated during workpiece machining from the groove. The filtering mechanism 3 is set inside the groove and is used to filter out the waste chips in the cutting fluid or coolant. The filtering mechanism 3 includes a filter plate 31 that is slidably inserted into the insertion hole 12 and abuts against the top surface of the limit frame 11. A connecting plate 32 is fixedly connected to one side of the filter plate 31. Limiting members for limiting the filter plate 31 are provided on both sides of the CNC machine tool body 1 and at both ends of the connecting plate 32.

[0035] Specifically, when the CNC machine tool body 1 processes the workpiece, the waste generated falls onto the conveying mechanism 2. The coolant or cutting fluid used in the processing and some small waste chips pass through the conveying mechanism 2 and fall into the bottom of the groove. Due to the function of the filter plate 31, the small waste chips in the cutting fluid or coolant can be filtered out. The filtered coolant or cutting fluid falls to the bottom of the groove and flows out from the outlet pipe 15. The operator can place a collection bucket at the outlet pipe 15 to collect the filtered coolant or cutting fluid for recycling. Some larger waste materials are moved out of the groove by the conveying mechanism 2. The operator can place a collection box at the outlet end of the conveying mechanism 2 so that the larger waste materials fall into the collection box, which facilitates the recycling of waste generated during workpiece processing. When it is necessary to clean the filter plate 31, firstly, the two limiting pieces are disengaged from the connecting plate 32, then the filter plate 31 is pulled out of the groove and cleaned. After cleaning, it is reinserted into the groove, and the two limiting pieces are used to limit the connecting plate 32 to prevent the filter plate 31 from shifting position.

[0036] Example 1

[0037] like Figure 6As shown, in this embodiment, both ends of the side of the connecting plate 32 are provided with circular grooves 33. The limiting components include a slide rod 34, a slide plate 35, and an insert block 36. The slide rod 34 is fixedly connected to the side of the CNC machine tool body 1. The slide plate 35 slides through the outer wall of the slide rod 34 at the corresponding position. The insert block 36 is fixedly connected to the bottom end of the side of the slide plate 35 at the corresponding position and is inserted into the circular groove 33 at the corresponding position. One end of the slide rod 34 is fixedly connected to a stop block 37. A spring 38 is provided between the stop block 37 and the slide plate 35 at the corresponding position. A rubber pad is fixedly connected to the side of the connecting plate 32 that is connected to the filter plate 31. The length and width of the connecting plate 32 are both greater than the length and width of the insertion hole 12.

[0038] In this embodiment, by inserting the filter plate 31 into the groove, then rotating the two sliding plates 35 and compressing the two springs 38, the insertion block 36 is aligned with the corresponding circular groove 33. Then, the sliding plate 35 is moved so that the insertion block 36 is inserted into the corresponding circular groove 33. Since the filter plate 31 can be prevented from shifting position under the elastic action of the two springs 38, coolant or cutting fluid mixed with fine waste can be prevented from penetrating between the filter plate 31 and the inner side of the groove.

[0039] Example 2

[0040] like Figure 5 As shown, in this embodiment, rectangular holes 13 communicating with the interior of the groove are provided on both opposite sides of the CNC machine tool body 1. Fixing blocks 14 are fixedly connected to both ends of the rectangular holes 13 on the back of the CNC machine tool body 1. The conveying mechanism 2 includes two symmetrical rollers and a conveyor belt 21. One of the two symmetrical rollers is rotatably connected between the two ends of the rectangular hole 13 on the front of the CNC machine tool body 1, and the other roller is rotatably connected between the two fixing blocks 14. The conveyor belt 21 is sleeved between the two rollers and is a mesh structure. The structure includes a circular roller located on the back of the CNC machine tool body 1, one end of which passes through a fixed block 14 at a corresponding position and is fixedly connected to a pulley 22. A circular rod is rotatably connected between the two fixed blocks 14. A brush roller 23 that contacts the conveyor belt 21 is fixedly connected to the outer wall of the circular rod. One end of the circular rod passes through a fixed block 14 at a corresponding position and is fixedly connected to a pulley 24 that is connected to the pulley 22 via belt drive. A motor 25 is fixedly connected to the back of the CNC machine tool body 1. The output end of the motor 25 is fixedly connected to the circular rod. The diameter of the pulley 22 is larger than the diameter of the pulley 24.

[0041] In this embodiment, the conveyor belt 21 can be rolled between two rollers by the drive of the motor 25. Since the surface of the conveyor belt 21 is a mesh structure, it is easy for cutting fluid or coolant to pass through the conveyor belt 21. The rolling conveyor belt 21 can remove some larger waste materials from the groove and pour them into the pre-prepared collection box. At the same time, the drive of the motor 25 can rotate the brush roller 23. The rotating brush roller 23 can clean away some small waste materials adsorbed on the surface of the conveyor belt 21 (due to the action of coolant or cutting fluid, some small waste materials will be adsorbed on the surface of the conveyor belt 21), thereby preventing them from mixing with the small waste materials generated when processing other metal workpieces in the next process.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
