Description

Technical Field

[0001] This utility model relates to the field of CNC vibrating cutters, and in particular to a waste material processing device for CNC vibrating cutter cutting machines. Background Technology

[0002] CNC vibratory cutter is an automated processing equipment that integrates computer numerical control technology and high-frequency vibration cutting principle. Its core function is to achieve efficient and high-precision cutting of various flexible and medium-hard materials by controlling the high-frequency micro-amplitude vibration and precise motion trajectory of the tool through program control. It is widely used in the field of non-metallic material processing.

[0003] In existing technologies, when CNC vibratory cutters cut scrap, a built-in motor drives the blade to vibrate vertically at high frequency and micro-amplitude. Combined with the precise trajectory of the CNC system, this results in high-frequency impact cold cutting of flexible or medium-hard non-metallic materials, producing fine scrap. For scrap handling, most equipment is equipped with an automated cleaning system. An electric telescopic rod drives a scraper to scrape the scrap onto a movable table, which is then tilted to allow it to fall into a collection box. Some systems also include a dust extraction system to remove lightweight scrap, ensuring processing accuracy and a clean environment.

[0004] In existing technologies, fixed screens rely on gravity screening, which is prone to clogging due to material adhesion and poor flowability, resulting in low efficiency. Materials that do not meet the standards lack a stable closed-loop recycling path and usually need to be manually collected and fed back into the crushing mechanism. It is difficult to ensure that all materials reach the preset crushing particle size, ultimately reducing the thoroughness and overall efficiency of the crushing process. To address these issues, a crushing device for a CNC vibrating knife cutting machine is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a waste material processing device for a CNC vibrating knife cutting machine, which aims to solve the problems of low efficiency of fixed screens, high dependence on manual labor, and unstable recycling quality in the existing technology, making it difficult to meet the industry's technical requirements for continuous and low-loss processing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a waste material processing device for a CNC vibrating knife cutting machine, comprising a housing, a cutting mechanism and a conveying mechanism provided on the inner wall of the housing, the cutting mechanism including a protective box, the outer wall of the protective box being fixedly connected to the inner wall of the housing, a rotating rod being rotatably connected to the inner wall of the protective box, the outer wall of the rotating rod being rotatably connected to the inner wall of the housing, a pulley one being fixedly connected to the outer wall of the rotating rod, a pulley two being connected to the outer wall of the pulley one via belt drive, a reciprocating screw being fixedly connected to the inner wall of the pulley two, the outer wall of the reciprocating screw being rotatably connected to the inner wall of the housing, a slider being threadedly connected to the outer wall of the reciprocating screw via a threaded sleeve, a sliding frame being slidably connected to the inner wall of the slider, a hinge rod being hinged to the outer wall of the sliding frame, a screening screen being hinged to the other end of the hinge rod, a limit shaft being rotatably connected to the inner wall of the screening screen, and the outer wall of the limit shaft being fixedly connected to the inner wall of the housing.

[0007] As a further description of the above technical solution: The cutting mechanism also includes a rotating shaft, the top end of which is fixedly connected to the bottom end of the rotating rod, and a blade is fixedly connected to the outer wall of the rotating shaft.

[0008] As a further description of the above technical solution: The cutting mechanism also includes a motor, the outer wall of which is fixedly connected to the top of the housing, and the output shaft of the motor is fixedly connected to the rotating rod.

[0009] As a further description of the above technical solution: The cutting mechanism also includes a limiting frame, the outer wall of which is fixedly connected to the outer wall of the protective box, and the limiting frame is elastically connected to a fixing plate by a spring.

[0010] As a further description of the above technical solution: One end of the spring is fixedly connected to the inner wall of the limiting frame, and the other end of the spring is fixedly connected to the top of the fixing plate. The outer wall of the fixing plate is slidably connected to the inner wall of the limiting frame, and the bottom of the fixing plate abuts against the top of the screening mesh plate.

[0011] As a further description of the above technical solution: The cutting mechanism also includes a feeding plate, the outer wall of which is fixedly connected to the inner wall of the housing, and the outer wall of the feeding plate is fixedly connected to the outer wall of the protective box.

[0012] As a further description of the above technical solution: The cutting mechanism also includes a collection box, the outer wall of which is slidably connected to the inner wall of the housing.

[0013] As a further description of the above technical solution: The conveying mechanism includes a limiting cylinder, the outer wall of which is fixedly connected to the inner wall of the housing, a conveying auger is rotatably connected to the inner wall of the limiting cylinder, a pulley three is fixedly connected to the top of the conveying auger, the outer wall of the pulley three is connected to the outer wall of the rotating rod via a belt, and a discharge pipe is fixedly connected to the outer wall of the limiting cylinder.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a cutting mechanism, the crushed material is driven by a reciprocating screw and a hinge rod to operate the screening screen plate, so that the material that meets the particle size falls smoothly into the collection box, while the material that does not meet the particle size is tilted and bumped into the limiting cylinder by the screen plate. This can realize the effective screening and classification of materials, avoid the substandard material from being mixed with qualified material, and send it back to be crushed by the conveying auger, forming a closed-loop process, ensuring that all materials meet the standards, and improving the thoroughness and efficiency of crushing.

[0015] 2. In this utility model, by setting up a conveying mechanism, materials that are still too large after crushing can be effectively intercepted. Through the specific bumping method and inclined design of the screening screen, the material is prevented from falling to the side and accurately enters the limiting cylinder. Then, the conveying auger conveys the material upward and sends it back to the feed plate for re-crushing. This ensures that all materials can eventually reach the preset crushing particle size, thereby improving the crushing effect and the material qualification rate. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1-3The present invention provides an embodiment of a material handling device for a CNC vibrating knife cutting machine, comprising a housing 1. A cutting mechanism 2 and a conveying mechanism 3 are disposed on the inner wall of the housing 1. The cutting mechanism 2 includes a protective box 211, which protects the internal rotating rod 214 component to prevent material debris from interfering with rotation. The outer wall of the protective box 211 is fixedly connected to the inner wall of the housing 1. The housing 1 provides a support frame for the entire device, ensuring stable operation of each mechanism. The rotating rod 214 is rotatably connected to the inner wall of the protective box 211, and the rotating rod 214 serves as a power transmission mechanism. The core component drives the rotating shaft 212, pulley 228, and pulley 313 to rotate synchronously. The outer wall of the rotating rod 214 is rotatably connected to the inner wall of the housing 1. A pulley 225 is fixedly connected to the outer wall of the rotating rod 214. A pulley 228 is connected to the outer wall of the pulley 225 via a belt drive. The pulley 228 transmits the power of the rotating rod 214 to the reciprocating screw 220. The reciprocating screw 220 is fixedly connected to the inner wall of the pulley 228. The reciprocating screw 220 drives the slider 219 to perform reciprocating linear motion through rotation, which is the function of the screening screen. The oscillation of 216 provides power. The outer wall of the reciprocating screw 220 is rotatably connected to the inner wall of the housing 1. The outer wall of the reciprocating screw 220 is threadedly connected to the slider 219 via a threaded sleeve. The slider 219 moves under the action of the reciprocating screw 220, causing the sliding frame 218 to move synchronously. The inner wall of the slider 219 is slidably connected to the sliding frame 218. When the sliding frame 218 moves with the slider 219, it pushes the screening screen 216 to rotate around the limiting axis 215 through the hinge rod 217. The outer wall of the sliding frame 218 is hinged to the hinge rod 217, which transmits the sliding... The power of frame 218 is transmitted to screen plate 216, enabling the screen plate 216 to perform a wobbling screening action. The other end of hinge rod 217 is hinged to screen plate 216. Screen plate 216 screens the cut fragments by swinging. Smaller fragments fall into collection box 227, while larger fragments remain on the screen plate for further processing. The inner wall of screen plate 216 is rotatably connected to limit shaft 215. Limit shaft 215 provides a fulcrum for the rotation of screen plate 216, ensuring stable swing of screen plate 216. The outer wall of limit shaft 215 is fixedly connected to the inner wall of housing 1.

[0020] Reference Figures 2-4The cutting mechanism 2 also includes a rotating shaft 212, which transmits the power of the rotating rod 214 to the blade 213, causing the blade 213 to rotate and cut the material. The top end of the rotating shaft 212 is fixedly connected to the bottom end of the rotating rod 214, and the blade 213 is fixedly connected to the outer wall of the rotating shaft 212. The blade 213 cuts and crushes the material entering the device through high-speed rotation, meeting the material processing requirements. The cutting mechanism 2 also includes a motor 224, which provides the power source for the entire device and drives the rotating rod 214 to rotate continuously. The outer wall of the motor 224 is fixedly connected to the top of the housing 1, and the output shaft of the motor 224 is fixedly connected to the rotating rod 214. The cutting mechanism 2 also includes a limiting frame 221, which provides support for the spring 222 and the fixing plate 223. Provides installation and sliding space to ensure the stability of the elastic support structure. The outer wall of the limiting frame 221 is fixedly connected to the outer wall of the protective box 211. The limiting frame 221 is elastically connected to the fixing plate 223 through the spring 222. The fixing plate 223 connects the spring 222 and the screening screen plate 216, transmitting the elastic force of the spring 222 to the screening screen plate 216. One end of the spring 222 is fixedly connected to the inner wall of the limiting frame 221. The spring 222 provides buffer and restoring force for the swing of the screening screen plate 216 through its own elastic deformation, ensuring smooth screening action. The other end of the spring 222 is fixedly connected to the top of the fixing plate 223. The outer wall of the fixing plate 223 is slidably connected to the inner wall of the limiting frame 221. The bottom of the fixing plate 223 abuts against the top of the screening screen plate 216.

[0021] Reference Figures 3-5 The cutting mechanism 2 also includes a feed plate 226, which guides the material to be processed to accurately enter the cutting area of ​​the blade 213 of the cutting mechanism 2, avoiding material deviation. The outer wall of the feed plate 226 is fixedly connected to the inner wall of the housing 1 and the outer wall of the protective box 211. The cutting mechanism 2 also includes a collection box 227, which is used to collect larger fragments remaining on the screening screen 216 for easy subsequent cleaning or secondary processing. The outer wall of the collection box 227 is slidably connected to the inner wall of the housing 1. The conveying mechanism 3 includes a limiting cylinder 311, which provides an installation cavity for the conveying auger 312 and prevents fragment leakage during conveying. The outer wall of the casing 1 is fixedly connected to the inner wall of the housing 1. The inner wall of the limiting cylinder 311 is rotatably connected to the conveying auger 312. The conveying auger 312 conveys the larger fragments after screening along the limiting cylinder 311 to the discharge pipe 314 by rotating, so as to realize the discharge of the fragments. The top of the conveying auger 312 is fixedly connected to the pulley 313. The pulley 313 transmits the power of the rotating rod 214 to the conveying auger 312, driving it to rotate and convey the fragments. The outer wall of the pulley 313 is connected to the outer wall of the rotating rod 214 by a belt. The outer wall of the limiting cylinder 311 is fixedly connected to the discharge pipe 314. The discharge pipe 314 drops the fragments conveyed by the conveying auger 312 back onto the feed plate 226 for re-crushing.

[0022] Working principle: When it is necessary to crush waste materials, the motor 224 is started first. The output shaft of the motor 224 drives the rotating rod 214 to rotate. The rotating rod 214 drives the rotating shaft 212 inside the protective box 211 to rotate, so that the blades 213 on the rotating shaft 212 rotate at high speed to achieve crushing ability. On the other hand, it synchronously drives the pulley 228 and the pulley 313 to rotate. The pulley 228 drives the reciprocating screw 220 to rotate, so that the threaded sleeve on the reciprocating screw 220 drives the slider 219 to slide back and forth on the reciprocating screw 220. The inner wall of the slider 219 has a limit groove, which allows the sliding frame 218 to slide on the slider 219. This causes the hinge rod 217, which is hinged to the sliding frame 218, to have a pushing and pulling action, pulling the screening screen 216 to make up-and-down bumping motion. If the particle size does not meet the requirements, the waste material can be poured from the feed plate 226 into the protective box 211. The high-speed rotating blade 213 will quickly crush the material, and the crushed material will fall onto the screening screen plate 216. Since there is a fixing plate 223 at the hinge of the hinge rod 217 and the screening screen plate 216, the fixing plate 223 will bounce synchronously with the screening screen plate 216 on the inner wall of the limiting frame 221. The spring 222 inside the limiting frame 221 will generate a rebound force when the fixing plate 223 is lifted upward, which will tightly fit the fixing plate 223 and the inner wall of the limiting frame 221, effectively preventing the material from entering the slider 219 and avoiding affecting the normal sliding of the slider 219. Fine crushed material that meets the particle size requirements will pass through the mesh of the screening screen plate 216 and fall into the collection box 227 below for unified recycling.

[0023] When larger pieces remain after the waste materials are crushed, the screening screen 216 continuously bounces up and down. The screening screen 216 is raised on both sides to effectively prevent the materials from falling off. Because the screening screen 216 bounces in a circular motion on the limiting shaft 215, larger pieces will gradually fall into the limiting cylinder 311 due to the tilt angle. As the pulley 313 drives the conveying auger 312 to rotate, the materials gradually rotate upward under the rotation of the conveying auger 312, and then fall from the inclined discharge pipe 314 onto the feed plate 226, where the materials are crushed again to ensure that all materials reach the preset crushing particle size.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
