Description

Technical Field

[0001] This utility model relates to the field of waste material discharge and receiving devices, specifically a waste material discharge and receiving device for CNC machine tools. Background Technology

[0002] In the process of machining metal parts, machine tools such as grinding machines and milling machines are often used to cut and polish the parts. This machining process often generates a large amount of metal waste. To improve resource utilization efficiency, it is usually necessary to recycle this metal waste.

[0003] Patent application CN219649346U discloses a waste chip recycling and processing device and a CNC machine tool, relating to the field of machine tool waste recycling and processing. The waste chip recycling and processing device includes two inclined guide walls, a receiving channel located between the two guide walls and fixedly connected to the bottom of the guide walls, an arc-shaped channel connected to the receiving channel, a recycling bin connected to the tail end of the arc-shaped channel, and a pushing mechanism. The pushing mechanism is used to push the waste chips in the receiving channel to the arc-shaped channel. The arc-shaped channel is inclined upwards from one end near the receiving channel to the end near the recycling bin. This application has the effect of improving the recycling efficiency of waste chips generated by machine tools and compressing the recycled waste chips.

[0004] In practical applications, traditional waste discharge and receiving devices typically have guide walls and receiving channels directly installed inside CNC machine tools. By guiding and receiving, waste fragments fall directly into the recycling bin for collection and processing. However, after the waste fragments are collected, further processing is required, such as crushing the fragments. This necessitates continuous transfer of the waste fragments and the installation of multiple devices, making the overall process inconvenient. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a CNC machine tool waste discharge and receiving device. This solves the problem that current traditional waste discharge and receiving devices typically set up guide walls and receiving channels directly inside the CNC machine tool, using guiding and receiving methods to allow waste debris to fall directly into the recycling bin for collection and processing. However, after the waste debris is collected, subsequent recycling and processing, such as crushing, is still required, which necessitates continuous transfer of waste debris and the installation of multiple devices, making the overall process inconvenient.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a CNC machine tool waste discharge and receiving device is designed, including a machine tool body, an operating room is provided at the front end of the machine tool body, a waste trough is provided at the bottom of the operating room, crushing rollers are installed on both sides inside the waste trough, a rotating rod is passed through the crushing roller, and the rotating rod is fixedly connected to the crushing roller at the through position, one end of the rotating rod is connected to the output shaft of the drive motor installed on the surface of the machine tool body through a coupling, and the other end is rotatably connected to the inner wall of the waste trough through a bearing, and transmission components are provided at both ends of the external part of the rotating rod for striking the filter screen plate in the waste trough and driving it to move up and down.

[0007] In practical applications, the waste generated during processing first enters the waste trough. The drive motor drives the rotating rod to rotate, causing the crushing rollers on both sides to operate, thereby crushing the waste. During the rotation, the transmission components outside the crushing rollers periodically strike the filter screen, causing it to vibrate up and down. This achieves simultaneous crushing and screening of the waste, avoiding the complex process of transferring the waste to a separate crushing device, and greatly improving the overall processing efficiency.

[0008] Preferably, the transmission assembly includes multiple elliptical blocks, which are installed through and fixedly connected to both ends of the rotating rod.

[0009] In practical applications, the irregular shape of the elliptical block during rotation can periodically change the contact point with the filter screen, forming an alternating knocking and releasing action, thereby causing the filter screen to vibrate regularly, improving the screening efficiency of waste materials and accelerating the solid-liquid separation process.

[0010] Preferably, the bottom side of the machine tool body is provided with an outlet hole, which is connected to a waste trough located in the operating chamber.

[0011] Preferably, a side baffle is provided on the outside of the outlet hole body, a handle is fixed on one side of the side baffle, and a filter screen is installed on the other side. The filter screen extends through the outlet hole body into the waste tank and maintains a gap with the bottom of the waste tank.

[0012] In practical applications, the filter screen acts as a filter layer, blocking particles from being discharged directly while leaving gaps to allow liquid to pass through, thus enabling the device to achieve solid-liquid separation.

[0013] Preferably, the filter screen plate has multiple rotating wheels at one end of the bottom of the waste trough. The rotating wheels are disposed in the concave plate body and connected to the output shaft inside the concave plate body. The output shaft passes through the concave plate body and is connected to the first motor installed on its side.

[0014] In practical applications, the first motor drives the output shaft to rotate the wheel, thereby pushing the filter screen to move back and forth or in and out. The filter screen can actively enter and exit the tank without manual pulling, reducing labor intensity and improving the degree of automation.

[0015] Preferably, the bottom of the concave plate is connected to a second motor via an output shaft, and the second motor is installed in the mounting groove at the top of the movable column.

[0016] In practical applications, the second motor adjusts the angle of the rotating wheel to laterally limit the filter screen, thus preventing displacement of the filter screen caused by the rotating wheel being longitudinally positioned at the bottom of the filter screen during the initial impact.

[0017] Preferably, the bottom of the movable column extends into the fixed cylinder and is connected to a spring located inside the fixed cylinder, and the fixed cylinder is installed at the bottom of the waste trough.

[0018] In practical applications, when the filter screen vibrates or is subjected to external force, the moving column will compress the spring, and then the spring will release to provide a restoring force, which plays a role in buffering and resetting, preventing the components from being damaged due to excessive vibration and extending the service life of the device.

[0019] Preferably, a waste liquid tank is installed at the bottom of the machine tool body, and the top of the waste liquid tank is connected to the waste material tank for collecting the waste liquid after solid-liquid separation. The bottom of the waste liquid tank is connected to an outlet pipe, and a pipe cap is installed at the bottom of the outlet pipe.

[0020] In practical applications, the screened liquid waste flows into the waste liquid tank, is stored in a centralized manner, and can be discharged through the liquid outlet pipe, realizing the separation and centralized recycling of solid and liquid waste, which facilitates secondary treatment or reuse and avoids environmental pollution caused by the leakage of liquid waste.

[0021] Preferably, each of the four corners of the bottom of the waste liquid tank is fixed with one end of a support column, and the other end of the support column is fixed with a device base plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets a waste trough at the bottom of the machine tool's main operating chamber and installs crushing rollers on both sides of the waste trough. The crushing rollers rotate under the action of a drive motor, which can crush the waste. This avoids the cumbersome process of transferring the waste fragments to other crushing equipment, and realizes the integration of waste collection and crushing. Compared with the prior art, it solves the problem that the waste fragments still need to be transferred and processed. At the same time, the transmission component set outside the crushing roller can continuously strike the filter screen plate during operation, so that the filter screen plate squeezes the rotating wheel and concave plate up and down, and vibrates through the spring at the bottom of the squeezed fixed cylinder, thereby accelerating the solid-liquid separation efficiency. The solid waste can fall and be discharged in time, while the liquid waste is collected in a centralized waste liquid tank at the bottom, realizing the simultaneous solid-liquid separation and reducing the difficulty of subsequent processing. 2. This utility model, through the combination of filter screen plate, rotating wheel and concave plate, can not only use multiple first motors to drive multiple rotating wheels to rotate, thereby actively moving the filter screen body in and out without the need for manual pulling of the filter screen body, but also use a second motor to control the angle of the rotating wheel to limit the position of the filter screen body and adjust the filter screen plate. At the same time, during the up and down movement of the filter screen body, the cooperation of the moving column and spring can play a buffering and resetting role during the operation of the equipment.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A waste material discharge and receiving device for CNC machine tools, see [link / reference] Figures 1 to 4 The machine tool body 1 includes an operating chamber 101 at the front end of the machine tool body 1. A waste trough 2 is located at the bottom of the operating chamber 101. Crushing rollers 201 are installed on both sides inside the waste trough 2. A rotating rod 207 passes through the crushing rollers 201 and is fixedly connected to the crushing rollers 201 at the through-point. One end of the rotating rod 207 is connected to the output shaft of a drive motor 204 installed on the surface of the machine tool body 1 via a coupling. The other end is rotatably connected to the inner wall of the waste trough 2 via a bearing. Transmission components are provided at both ends of the rotating rod 207 to strike the filter screen 206 inside the waste trough 2 and drive it to move up and down. The chips and coolant generated during the processing first enter the waste tank 2 under the action of gravity, avoiding overflow and spillage. The drive motor 204 drives the rotating rod 207 to rotate through the coupling, so that the crushing rollers 201 on both sides rotate synchronously, shearing and squeezing the incoming waste, breaking the larger waste into smaller particles, and squeezing out the mixed liquid components at the same time.

[0029] For details, see Figure 2 The transmission assembly includes multiple elliptical blocks 208, which are installed through and fixedly connected to both ends of the rotating rod 207. The bottom side of the machine tool body 1 has an outlet hole 205, which communicates with the waste trough 2 located in the operating chamber 101. A side baffle 202 is provided on the outside of the outlet hole 205. A handle 203 is fixed on one side of the side baffle 202, and a filter screen 206 is installed on the other side. The filter screen 206 passes through the outlet hole 205 and extends into the waste trough 2, maintaining a gap with the bottom of the waste trough 2.

[0030] During rotation, the elliptical block 208 fixed outside the crushing roller 201, due to its eccentric shape, can periodically strike the filter screen plate 206, producing an alternating contact and release effect, thereby causing the filter screen plate 206 to vibrate up and down in a regular manner. During the up and down movement, the filter screen plate 206 will compress the spring 305 inside the fixed cylinder 3, and then rebound under the reset action of the spring 305, forming a continuous vibration cycle.

[0031] Further, see Figure 3 and Figure 4The filter screen 206 is located at the bottom of one end of the waste tank 2 and is provided with multiple rotating wheels 303. The rotating wheels 303 are set in the concave plate 301 and are connected to the output shaft in the concave plate 301. The output shaft passes through the concave plate 301 and is connected to the first motor 302 installed on its side. The bottom of the concave plate 301 is connected to the second motor 307 through the output shaft. The second motor 307 is installed in the mounting groove 304 at the top of the moving column 306. The bottom of the moving column 306 extends into the fixed cylinder 3 and is connected to the spring 305 located in the fixed cylinder 3. The fixed cylinder 3 is installed at the bottom of the waste tank 2.

[0032] When the filter screen 206 is struck and moved downwards by the elliptical block 208, the moving column 306 drives the spring 305 to compress and store energy. After the impact force disappears, the spring 305 rebounds and releases energy, causing the filter screen 206 to return to its original position. This allows the screen to obtain a stable working amplitude and frequency, enhancing its screening capacity. When the filter screen 206 needs to be moved out or fed in, the first motor 302 is activated. The first motor 302 drives the output shaft inside the concave plate 301, causing the rotating wheel 303 to rotate and apply a guiding force to the filter screen 206. This enables the screen to actively move in and out along the direction of the outlet hole 205 without manual pulling. The second motor 307 is used to drive the concave plate 301 and the rotating wheel 303 to rotate, thereby adjusting the angle of the rotating wheel 303 and laterally limiting the filter screen 206 to prevent it from shifting during vibration.

[0033] It is worth noting that, see Figure 1 The machine tool body 1 has a waste liquid tank 102 installed at the bottom. The top of the waste liquid tank 102 is connected to the waste material tank 2 for collecting the waste liquid after solid-liquid separation. The bottom of the waste liquid tank 102 is connected to the liquid outlet pipe 105. The bottom of the liquid outlet pipe 105 is equipped with a pipe cover 106. One end of the support column 103 is fixed at each of the four corners of the bottom of the waste liquid tank 102. The other end of the support column 103 is fixed with the device base plate 104.
