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.

[0012] Example: Figure 1-5As shown, this utility model provides a polyethylene pipe feeding device, including a workbench 1. A feeding assembly 3, a cutting assembly 4, and a clamping assembly 5 are installed on the workbench 1. A placement groove 2 is fixedly installed on the upper surface of the workbench 1. The feeding assembly 3 includes a sleeve 301, which is fixedly installed on the lower surface of the workbench 1. An extension rod 302 is slidably engaged inside the sleeve 301. A lead screw 312 is rotatably installed inside the sleeve 301 and threadedly inserted into the extension rod 302. A first motor 303 is fixedly installed at one end of the sleeve 301, and the output end of the first motor 303 is fixedly connected to one end of the lead screw 312. A sliding groove 304 is fixedly installed at one end of the extension rod 302, and a sliding shell 305 is slidably installed on the sliding groove 304. A plurality of first guide grooves 3051 are arranged in a ring on one side of the sliding shell 305. The first guide grooves 3051 are horizontal and vertical. A turntable 308 is rotatably installed inside the sliding shell 305. A plurality of second guide grooves 3082 are arranged in a ring on the turntable 308. The second guide grooves 3082 are inclined. A clamping rod 311 is slidably installed in each of the multiple second guide grooves 3082, and the clamping rod 311 is slidably locked in the corresponding first guide groove 3051. A third motor 309 is fixedly installed on one side of the sliding shell 305. A drive gear 310 is fixedly installed at the output end of the third motor 309. The outer ring of the turntable 308 may be provided with tooth grooves 3081, and the teeth of the drive gear 310 mesh with the corresponding tooth grooves 3081 on the turntable 308. A threaded rod 306 is rotatably installed inside the slide groove 304, and the threaded rod 306 is threadedly inserted into the back of the sliding shell 305. A second motor 307 is fixedly installed at the top of the slide groove 304, and the output end of the second motor 307 is fixedly connected to the top of the threaded rod 306. First, the polyethylene pipe to be cut is placed in the placement groove 2 on the workbench 1, so that one end of the pipe is flush with the end of the placement groove 2 near the cutting component 4, and is clamped and fixed by the clamping component 5. Then, according to the pipe diameter, the second motor 307 drives the threaded rod 306 to rotate, and the threaded rod 306 drives the sliding shell 305 to slide and rise and fall along the slide groove 304 (the sliding shell 305 is square), so that the center point of the sliding shell 305 is aligned with the center of the pipe. Next, the first motor 303 drives the lead screw 312 to rotate. The lead screw 312 drives the extension rod 302 to slide and retract within the sleeve 301. The extension rod 302 drives the sliding groove 304 and the sliding shell 305 to slide towards the pipe, so that the clamping rod 311 on the sliding shell 305 is inserted into the pipe. Then, the third motor 309 drives the drive gear 310 to rotate. The drive gear 310 meshes with the toothed groove 3081 on the turntable 308, driving the turntable 308 to rotate. The turntable 308 drives multiple clamping rods 311 to slide away from each other through the guidance of the second guide groove 3082 and the first guide groove 3051, thereby clamping one end of the pipe from the inner wall of the pipe. During use, rubber sleeves can be fitted on the clamping rods 311 to prevent damage to the inner wall of the pipe.The friction can be increased, then the clamping assembly 5 releases the pipe, and the first motor 303 drives the lead screw 312 to rotate. The lead screw 312 drives the extension rod 302 to slide out within the sleeve 301, pulling the pipe to the required cutting length. Finally, the cutting assembly 4 cuts the pipe.

[0013] The cutting assembly 4 includes a fixed frame 401, which is fixedly installed at one end of the workbench 1. A cutting blade 403 is slidably installed inside the fixed frame 401. A first cylinder 402 is fixedly installed at the top of the fixed frame 401, and the output end of the first cylinder 402 is fixedly connected to the top of the cutting blade 403. Limiting grooves 404 are provided on both sides of the interior of the fixed frame 401, and the cutting blade 403 can slide and rise along the limiting grooves 404. The first cylinder 402 can drive the cutting blade 403 to slide and rise within the fixed frame 401, and the cutting blade 403 can cut the pipe. The limiting grooves 404 can limit the stroke of the cutting blade 403, so that after the cutting blade 403 descends to its maximum stroke, the bottom end of the cutting blade 403 is lower than the bottom end of the placement groove 2 and does not contact the extension rod 302. The clamping assembly 5 includes two symmetrically distributed slide rods 501, which are inserted through one side of the top of the fixing frame 401. The bottom ends of the two slide rods 501 are fixedly installed with clamping plates 502. The top side of the fixing frame 401 is fixedly installed with a second cylinder 503, and the output end of the second cylinder 503 is fixedly connected to the upper surface of the clamping plate 502. The second cylinder 503 can be used to drive the clamping plate 502 to rise and fall, clamping and fixing the cut end of the pipe on the placement groove 2 and releasing the clamping. The slide rods 501 can limit and guide the clamping plate 502.

[0014] Working Principle: In use, the polyethylene pipe to be cut is first placed in the placement groove 2 on the workbench 1, with one end of the pipe flush with the end of the placement groove 2 closest to the cutting component 4. The second cylinder 503 lowers the clamping plate 502 to clamp and fix the cut end of the pipe in the placement groove 2. Next, according to the pipe diameter, the second motor 307 drives the threaded rod 306 to rotate. The threaded rod 306 drives the sliding shell 305 to slide and rise along the sliding groove 304, adjusting its position so that the center point of the sliding shell 305 aligns with the center of the pipe. Then, the first motor 303 drives the lead screw 312 to rotate. The lead screw 312 drives the extension rod 302 to slide and retract within the sleeve 301. The extension rod 302 causes the sliding groove 304 and the sliding shell 305 to slide towards the pipe, thus clamping the pipe on the sliding shell 305. Rod 311 is inserted into the pipe, and then the third motor 309 drives the drive gear 310 to rotate. The drive gear 310 meshes with the toothed groove 3081 on the turntable 308, causing the turntable 308 to rotate. The turntable 308 drives multiple clamping rods 311 to slide away from each other through the guidance of the second guide groove 3082 and the first guide groove 3051, so as to clamp one end of the pipe from the inner wall of the pipe. Then, the clamping assembly 5 releases the pipe, and the first motor 303 drives the lead screw 312 to rotate. The lead screw 312 drives the extension rod 302 to slide out in the sleeve 301, pulling the pipe to the required cutting length. Finally, the first cylinder 402 drives the cutting blade 403 to slide down in the fixed frame 401 to cut the pipe. This process is repeated to achieve the purpose of automatic feeding, which saves time and effort and is highly efficient.
