During the automatic sorting process, defective products can be identified and separated in a timely manner, avoiding the influx of unqualified products into the market. This automated process greatly reduces dependence on labor, reduces long-term labor costs and improves the safety of the production line, which is particularly important in environments where heavy or potentially hazardous materials are being processed.

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

A hand wheel 211 is fixedly sleeved on the end of the outer circumference of the threaded adjustment rod 210 away from the conveying motor 201, and an adjustment block 212 is threadedly sleeved on the outer circumference of the threaded adjustment rod 210. The bottom of the adjustment block 212 is fixedly connected with a synchronization block, and a limiting groove 228 is provided inside the positioning frame 207. The synchronization block is slidably connected to the inside of the limiting groove 228. A trigger switch fixing block 213 is fixedly connected to the bottom of the synchronization block, and a trigger switch 214 is installed on the trigger switch fixing block 213. An observation window 227 is provided inside the device housing 1, and the observation window 227 is used to observe the position of the adjustment block 212 to adjust the cutting length; An infrared transmitter 215 and an infrared receiver 216 are respectively installed inside the positioning frame 207 , and the infrared transmitter 215 and the infrared receiver 216 are symmetrically arranged.

[0021] like Figure 1 to Figure 9 As shown, the positioning and cutting assembly 2 also includes a cutting cylinder 217, which is installed on one side of the positioning frame 207, and a cylinder arm 218 is installed on the top of the cutting cylinder 217, and a moving block 219 is fixedly connected to the top of the cylinder arm 218, and an active rack 220 is fixedly connected to one side of the moving block 219; A linkage shaft 221 is rotatably installed inside the device housing 1, and a linkage gear 222 is fixedly sleeved on the outer circumference of the linkage shaft 221. A driven rack 223 is slidably installed inside the device housing 1. Both the active rack 220 and the driven rack 223 are meshed and connected with the linkage gear 222. A moving block 224 is installed on one side of the driven rack 223. A hot melt tool 226 is installed at the bottom of the moving block 224. A hot melt tool 1 225 is installed at the bottom of the moving block 1 219. The hot melt tool 1 225 and the hot melt tool 2 226 are symmetrically arranged. It also includes a controller, which is connected to the infrared receiver 216 and the trigger switch 214 signal, and is also connected to the cutting cylinder 217 control. The controller is suitable for controlling the action of the cutting cylinder 217 according to the action of the trigger switch 214 or the infrared receiver 216 and the trigger switch 214.

[0022] In this embodiment, the bellows is aligned with the conveying cavity formed between the conveying roller 1 203 and the conveying roller 2 206 and conveyed into the conveying cavity. At this time, the conveying roller 1 203 and the conveying roller 2 206 will guide and convey the bellows to the inside of the positioning frame 207. It should be noted that the speed of conveying can be adjusted by controlling the rotation speed of the conveying motor 1 201 and the conveying motor 2 204 through the control panel 5. As the bellows continues to be conveyed, it will contact the trigger switch 214 until the trigger switch 214 is pressed. The trigger switch 214 will send a signal to the controller, and the controller controls the start of the cutting cylinder 217 and can control the conveying motor 1 201 and the conveying motor 2 204 to stop. Correspondingly, the conveying roller 1 203 and the conveying roller 2 206 stop moving, and the cutting cylinder 217 The moving block 1 219 and the active rack 220 are driven to move upward together, and the active rack 220 is meshed with the linkage gear 222, so that the driven rack 223 which is also meshed with the linkage gear 222 moves downward, and the driven rack 223 drives the moving block 224 to move downward, and finally the moving block 1 219 and the moving block 2 224 move toward each other at the same time, and the corrugated tube is cut by the hot melt tool 1 225 and the hot melt tool 2 226. By using the hot melt tool, the cut surface can be smoother and the cutting is faster, which is convenient for improving the overall efficiency. In addition, it should be noted that the hot melt tool is a prior art, and the corrugated tube is locally heated by heating the blade or tool to soften or melt it, and then the hose is cut by applying a cutting force, which will not be described in detail here. Furthermore, by arranging a set of infrared transmitters 215 and infrared receivers 216 on one side of the interior of the positioning frame 207 close to the hot melt cutter, the cutting cylinder 217 will be started only when the trigger switch 214 is actuated and the infrared receiver 216 cannot receive the infrared rays emitted by the infrared transmitter 215 due to the obstruction of the bellows, thereby reducing the possibility of misoperation. It should be noted that the infrared transmitter 215 and the infrared receiver 216 are prior art, wherein the infrared transmitter 215 emits an infrared beam to the infrared receiver 216. If the beam is blocked by any object, the infrared receiver 216 cannot receive the infrared beam, thereby triggering a related control response. The use of this device is excellent in accuracy and response speed, greatly increasing safety, and will not be described in detail here. Finally, if it is necessary to produce corrugated tubes of different lengths, it is only necessary to turn the handwheel 211 disposed outside the device housing 1 and observe the position of the adjustment block 212 through the observation window 227. The handwheel 211 will drive the adjustment block 212 to move on the threaded adjustment rod 210 to adjust the cutting length, thereby improving the cutting efficiency and accuracy.

[0027] The classification component 3 also includes a waste storage basket 327 , which is located on one side of the device housing 1 .

[0028] In this embodiment, after the bellows is cut to length in Embodiment 1, it will fall down into the groove inside the material block 312 along the slide groove in the middle of the positioning frame 207, and the weight of the bellows will be weighed by the gravity scale 313 set in the groove. At the same time, the conveying shaft 205 will drive the transmission gear 1 303 to rotate through the synchronous belt 302, and the transmission gear 1 303 will achieve the deceleration effect by meshing with the transmission gear 2 305. Further, the rotating shaft 2 304 drives the active bevel gear 306 to rotate. The active bevel gear 306 drives the rotating shaft 308 to rotate through the driven bevel gear 307 meshing with it. The rotating shaft 308 will drive the lifting cam 309 to rotate at the same time. The lifting cam 309 will push up the push block 311 when it reciprocates. At this time, the push block 311 will rotate with the feeding shaft 310 as the axis until the lifting cam 309 is separated from the push block 311. The push block 311 will reset under the drive of gravity until the next circle of the lifting cam 309 rotates. When the push block 311 rotates, it will drive the lower The material block 312 rotates together, and the corrugated tube inside the lower material block 312 is sent to the long plate 318. At this time, the gravity scale 313 detects that the weight on its top has dropped, and the controller will start the positioning motor 314. The positioning motor 314 will drive the rotating block 315 to rotate, and the rotating block 315 will drive the positioning connecting rod 316 movably hinged at both ends to move. Because the two centering plates 320 are slidably connected to the guide plate 326 and the inside of the long plate 318 at the same time, when the positioning motor 314 is started, the centering plates 320 on both sides are 0 will move toward the center at the same time to clamp the two ends of the bellows until the clamping contact switches 332 set on the two centering plates 320 are pressed at the same time. At this time, it is determined that the centering is completed, and a signal is sent to the controller. The controller turns off the positioning motor 314. At this time, the bellows continues to move downward along the direction of the chute 319 to complete the self-centering effect until the next signal from the gravity scale 313 is received. The positioning motor 314 first starts in the reverse direction, resets, and then starts in the forward direction to perform self-centering of the next pipe; Furthermore, after the gravity scale 313 weighs the bellows and obtains a weighing signal, the weighing signal is sent to the controller, and the controller starts the action of the rotating plate device corresponding to the corresponding weight signal. The rotating plate device receives the signal and rotates 90 degrees to open the channel connected to the material guide block, so that the bellows enters the corresponding storage channel and finally enters the interior of the material storage block 331. In addition, if the weight does not meet the set value after weighing, it is judged as a defective product, and the three rotating plate devices will not be started. At this time, the bellows will slide along the chute 319 into the waste storage basket 327 for recycling; The above-mentioned embodiments improve operational efficiency and reduce human errors, ensure the accuracy of product classification, and thus improve product quality. At the same time, this automated process also reduces dependence on manpower, reduces long-term labor costs, and improves the safety of the working environment, especially when handling heavy or hazardous materials. In addition, it increases the adaptability of production.
