Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment in CNC machines, in particular to a waste recovery and cleaning device in a CNC machine. Background Art

[0002] A CNC machine is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions and decode them to enable the machine tool to move and process parts. During processing, a certain amount of waste will be generated. In order to save costs and achieve resource recycling, the waste needs to be recycled.

[0003] For example, a fully automatic CNC machining center waste recovery device, with the publication number CN210968027U, adds a fan on the top of the CNC machining center shell and installs a splitter at the output port of the fan to divide the wind force generated by the fan into seven equal parts. The wind head is aimed downward at the processing table. During processing, the waste is effectively blown onto the surface of the conveyor belt. In addition, there is an electromagnet under the conveyor belt. The attraction of the electromagnet is used to effectively adsorb the metal waste on the conveyor belt. The waste is transported through the conveyor belt until it is placed in the waste bucket outside the CNC machining center shell. The staff only needs to wait until the bucket is full to replace it.

[0004] However, during the machining process of the machine tool, debris of various sizes will be generated. When the debris of various sizes is removed by blowing, the smaller debris will diffuse and enter other locations in the machine tool, resulting in incomplete debris removal. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4The figure shows a waste recycling and cleaning device for a CNC machine, comprising a machine tool body 1, a workpiece is placed on an operating station in the machine tool body 1, and the machine tool body 1 is used to cut or ultrasonically separate the workpiece, and a distribution box 2 is installed below the operating station in the machine tool body 1, and a filter plate 3 is hinged near the middle position of the distribution box 2, and the distribution box 2 is away from the hinged side of the filter plate 3. There is a hollow setting for discharging materials. When the machine tool body 1 is running, the generated waste and the processed finished materials fall onto the filter plate 3 at the same time. Under the screening effect of the filter plate 3 of the filter plate 3, the waste enters the bottom of the distribution box 2, while the finished materials are trapped on the surface of the filter plate 3. When collecting the finished materials, it is only necessary to swing and tilt the filter plate 3 so that the finished materials on the filter plate 3 slide under the action of gravity and slide out along the hollow part of the side of the distribution box 2. An exhaust fan 11 is connected to the bottom edge of the hollow part of the distribution box 2. 2 The bottom of the inner box is located at the air inlet of the exhaust fan 11, and a filter cover 10 is fixedly installed thereon, and the bottom of the inner box of the distribution box 2 is located at the outer bottom edge of the filter cover 10 and is hollowed out. The suction force generated by the exhaust fan 11 can generate a negative pressure environment at the operating station of the machine tool body 1, thereby ensuring that the waste materials generated during the processing, such as dust, smoke or powder, are dispersed in the machine tool body 1, but are sucked onto the surface of the filter plate 3 under the negative pressure environment. The filter cover 10 is set to prevent the dust, powder and other waste materials that enter the bottom of the inner box of the distribution box 2 from being discharged through the exhaust fan 11 and cannot be effectively collected. The outer bottom of the distribution box 2 is fixedly connected with a channel 18 covering the hollowed-out bottom edge of the filter cover 10. One end of the channel 18 extends to the outside of the machine tool body 1 and the end of the channel 18 is connected to the waste box 4. Larger waste enters the channel 18 under the action of gravity and slides through the channel 18 to the waste box 4 for collection.

[0024] In order to ensure that the waste passes through the filter plate 3 quickly: a number of spring parts 5 are connected between the bottom of the distribution box 2 and the machine tool body 1, and the end face of the fan shaft of the exhaust fan 11 is fixedly connected to the eccentric wheel 12. The rotation of the exhaust fan 11 drives the eccentric wheel 12 to rotate, and then the overall vibration of the distribution box 2 is achieved under the elastic support of the number of spring parts 5, that is, the vibration of the filter plate 3 is achieved, thereby accelerating the waste to pass through the filter plate 3.

[0025] In order to collect the finished materials on the filter plate 3: the bottom of the distribution box 2 is rotatably connected to an electric push rod 6, the telescopic end of the electric push rod 6 is hinged to the swinging edge of the bottom surface of the filter plate 3, and the horizontal filter plate 3 can be tilted downward and opened by contracting the electric push rod 6.

[0026] The bottom of the material distribution box 2 is slidably installed with a sealing plate 8 for closing the hollowed-out bottom edge of the filter cover 10, and the sealing plate 8 is also connected to the bottom of the material distribution box 2 by an electric push rod 6. The electric push rod 6 in the scheme here can be used to control the opening and closing of the sealing plate 8, thereby preventing the outside wind from entering the material distribution box 2 along the channel 18 during the operation of the exhaust fan 11, resulting in air flow dispersion and the negative pressure at the box mouth of the material distribution box 2 being reduced, affecting the extraction effect, and the bottom of the material distribution box 2 is fixedly connected with a guide frame 7 that passes through the surface of the sealing plate 8, and the outer wall of the filter cover 10 is slidably installed with a cleaning plate 9. The two sides of the cleaning plate 9 are penetrated by a guide shaft 16 fixed to the bottom of the inner box of the material distribution box 2. The two sides of the cleaning plate 9 are hinged with an inclined plate 15 and a spring rod 14 is connected between the free edge of the inclined plate 15 and the bottom of the inner box of the material distribution box 2. A pull rope 13 is fixedly connected to both sides of the bottom surface of the plate 9, one end of the pull rope 13 is connected to the closing plate 8 and the pull rope 13 moves in an L-shaped route. A rope threading block 17 is fixedly connected to the inner wall of the distribution box 2, which is sleeved on the pull rope 13 and slidably connected to the upper surface of the closing plate 8. When the closing plate 8 slides open when the exhaust fan 11 is stopped, the closing plate 8 pulls the pull rope 13 to move under the blocking action of the rope threading block 17, and the pull rope 13 will pull the cleaning plate 9 down along the surface of the filter cover 10 to clean the surface of the filter cover 10. In addition, when the cleaning plate 9 descends, it will force the inclined plate 15 to move down and drive the spring rod 14 at its free end to elastically contract, thereby ensuring that when the closing plate 8 slides to close the channel 18, the spring rod 14 elastically stretches and resets, which can drive the cleaning plate 9 to rise along the surface of the guide shaft 16, thereby realizing the re-straightening and tightening of the pull rope 13.

[0027] Working principle: fix the distribution box 2 below the workpiece processing position in the machine tool body 1, and use the suction force generated by the operation of the exhaust fan 11 to extract the waste generated during the workpiece processing to the surface of the filter plate 3, and under the action of vibration, the waste passes through the filter plate 3 into the bottom of the distribution box 2, and the workpiece will fall on the filter plate 3 after processing. The workpiece is tilted by the filter plate 3 to make it slide out, and at the same time the exhaust fan 11 stops running, and then the sealing plate 8 slides open, and under the traction of the pull rope 13, the cleaning plate 9 is simultaneously lowered to clean the waste on the surface of the filter cover 10, and the waste and the waste scraped by the cleaning plate 9 enter the waste box 4 along the opened channel 18 for collection.

[0028] The wiring diagram of the machine tool body 1, the electric push rod 6 and the exhaust fan 11 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the machine tool body 1, the electric push rod 6 and the exhaust fan 11 are no longer explained in detail.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
