[0002] During the CNC machine tool processing, a large amount of waste and chips will be generated during the processing. These wastes not only take up space, but also cause waste of resources and environmental pollution. The CNC machine tool waste recovery device is a device used to recover the waste and chips generated during the CNC machine tool processing. With the development of the manufacturing industry and the increasing requirements for resource conservation and utilization, the development of such a device is of great significance for improving production efficiency, reducing waste emissions and saving resources.

[0003] After searching, the existing patent (publication number: CN220806505U) discloses a waste recovery device for CNC machine tool processing, including a CNC machine tool, a water tank is arranged inside the bottom end of the CNC machine tool, a support is slidably installed on the water tank, a plurality of universal wheels are arranged at the bottom end of the support, a first screw and a second screw are rotatably installed in both ends of the support, a hand wheel is arranged on one end of the first screw, a first slider is threadedly connected to the first screw, a second slider is threadedly connected to the second screw, a connecting rod is rotatably installed on the first slider and the second slider, a rotating plate is rotatably installed on the support, and a waste trough is arranged on the bottom end of the rotating plate. In the utility model, the support is moved by the arrangement of the universal wheels, and the rotatable rotating plate and the waste trough fixed at the bottom end of the rotating plate are arranged so that the waste trough can move with the support, thereby facilitating the transfer and dumping of the waste produced by the CNC machine tool processing, and the cleaning efficiency is high.

[0004] However, in the actual use of the above scheme, during the CNC machine tool processing, chips are one of the most common waste materials in CNC lathe processing. They are thin slices or thin strips cut from metal materials during the cutting process. The shape and size of the chips depend on the type of tool used, the cutting speed and the material properties. However, direct storage will affect the waste storage capacity due to the large gaps between the chips, thereby reducing the efficiency of waste treatment.

[0005] To this end, the utility model provides a waste material recovery device for a numerically controlled machine tool. Utility Model Content

[0006] In order to make up for the shortcomings of the prior art and solve the problem that directly collecting and storing chips will affect the waste storage capacity due to large gaps between the chips, thereby reducing the waste processing efficiency, the utility model proposes a waste recovery device for CNC machine tools.

[0008] The crushing structure includes a moving knife, a crushing box is fixedly connected to the top of the second conveying pipe, a lower hopper is fixedly connected to the inner side of the top of the crushing box, a uniformly distributed fixed knife is fixedly connected to the inner bottom of the lower hopper, a transmission rod is rotatably connected to the inner side of the fixed knife, a uniformly distributed moving knife is fixedly connected to the outer side of the top of the transmission rod, a universal joint is fixedly connected to the bottom end of the transmission rod, and the right side of the bottom end of the universal joint is fixedly connected to the left middle end of the spiral blade;

[0009] Through the above technical solution, the motor uses the spiral blades, universal joints and transmission rods to drive the movable knife to rotate, and cooperates with the fixed knife to crush the chips. As a result, the volume of the chips is reduced after crushing, which can greatly save storage space.

[0010] Furthermore, a guide ring is fixedly connected to the bottom end of the fixed blade;

[0011] Through the technical solution, the machine is fixed, so that the crushed chips and cutting fluid mixture are guided to the surroundings.

[0012] Further, the solid-liquid separation structure comprises a first conveying pipe, a filter cylinder is fixedly connected to the inner side of the separation cylinder, the filter cylinder is rotatably connected to the spiral blade, and the bottom end of the separation cylinder is fixedly connected to the first conveying pipe;

[0013] Through the above technical scheme, the filter cylinder is fixed by the separation cylinder, and the spiral blade is driven by the motor to rotate in the filter cylinder, so that the crushed waste on the left side is pushed to the right side by the spiral blade. In the process, the cutting fluid is filtered and separated by the filter cylinder to filter out impurities and grease, and then it is transported back to the cutting fluid storage box of the CNC machine tool through the first delivery pipe for reuse.

[0014] Furthermore, the transmission structure includes a protective hose, and the outer sides of the two ends of the universal joint are provided with left and right opposite protective hoses, and the outer side of the middle end of the universal joint is rotatably connected with a fixing frame, and the fixing frame is fixedly connected to the inner wall of the second conveying pipe;

[0015] Through the above technical solution, a transmission chain is formed by connecting two universal joints, and the middle end of the transmission chain is limited by a fixed frame, thereby forming a stable transmission. At the same time, the universal joint is protected by a protective hose to prevent waste from entering the universal joint shaft when the universal joint is running, thereby affecting its use.

[0016] Furthermore, the connection position between the universal joint and the transmission rod is located inside the bottom end of the guide ring;

[0017] Through the above technical solution, by setting the connection point between the universal joint and the transmission rod on the inner side of the bottom end of the guide ring, because the universal joint and the transmission rod have different diameters, waste accumulation can be avoided at the connection.

[0018] Furthermore, the outer side of the separation cylinder is fixedly connected with evenly distributed support legs;

[0019] Through the above technical solution, the separation cylinder and the escort pipe are supported and fixed by the supporting legs.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model discloses a waste recycling device for CNC machine tools, which crushes waste materials through a crushing structure, so that the volume of chips is reduced after crushing, which can greatly save storage space. At the same time, the density of chips after crushing is higher, so more chips can be stored in a limited storage space, thereby improving storage efficiency.

[0022] 2. The utility model describes a waste recovery device for CNC machine tools, in which a motor drives a spiral blade to rotate, thereby pushing the waste transported by the escort pipe to the right through the spiral blade. During the pushing process, the waste and waste liquid are separated into solid and liquid through the filter cartridge, and at the same time, the waste liquid is filtered through the filter cartridge to filter out various impurities therein so that it can be reused, thereby reducing production costs.
