Description

Technical Field

[0001] This utility model relates to the field of composite pipe processing technology, and in particular to a steel wire stripping device for reinforced polyethylene composite pipes. Background Technology

[0002] Polyethylene composite pipe refers to a pipe made by simultaneously extruding two different densities of polyethylene resin using two separate extruders, and then extruding the molten material into a mold that can form a composite pipe. The formed pipe is a polyethylene composite pipe. Reinforced polyethylene composite pipe refers to a polyethylene composite pipe with steel wires inside. After the reinforced polyethylene composite pipe is used, the steel wires inside can be recycled. Therefore, it is necessary to remove the steel wires inside the reinforced polyethylene composite pipe.

[0003] A search of Chinese Patent Publication No. CN218692494U reveals a device for stripping steel wire from waste reinforced polyethylene composite pipes. The device includes a counterweight plate, a mounting ring plate welded above the counterweight plate, and two auxiliary ring plates. The inner wall of the mounting ring plate has multiple annularly arranged notches. These notches are rotatably connected via a rotating shaft to a circular cutter for cutting the outer surface of the waste reinforced polyethylene composite pipe. Multiple annularly arranged electric push rods are connected to the sides of the auxiliary ring plates. Each electric push rod is connected to a lifting lug via a pressure sensor. The lifting lug is rotatably connected to a clamping wheel via a rotating rod. A mounting plate is connected to the side of one of the lifting lugs, and a forward / reverse motor is connected to the side of the mounting plate. The output shaft of the forward / reverse motor passes through the lifting lug and is fixedly connected to one of the rotating rods via a coupling. The extension of the electric push rod causes the clamping wheel to press against the reinforced polyethylene composite pipe. The forward / reverse motor drives the clamping wheel to rotate, thus conveying and moving the reinforced polyethylene composite pipe.

[0004] However, in the aforementioned patent, the distance between the multiple sets of circular cutters and the axis of the mounting ring plate is fixed, making it inconvenient to move the circular cutters to the appropriate position when dealing with reinforced polyethylene composite pipes of different sizes.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a steel wire stripping device for reinforced polyethylene composite pipe includes a base 1. Support legs 101 are fixedly connected to the four corners of the bottom of the base 1. Two sets of drive mechanisms are provided on the top of the base 1. The drive mechanism includes two sets of mounting seats 205 arranged front and rear. A rotary motor 206 is bolted to the top of the mounting seat 205. A drive wheel 207 is fixedly connected to the output shaft of the rotary motor 206. The two rotary motors 206 rotate in opposite directions. When the rotary motor 206 is started, the rotary motor 206 drives the drive wheel 207 to rotate, thereby driving the reinforced polyethylene composite pipe to move through the two sets of drive wheels 207 rotating in opposite directions.

[0027] The drive mechanism also includes an adjustment component for adjusting the distance between the two sets of mounting seats 205. The adjustment component includes a mounting frame 201 fixedly connected to the top of the base 1. A bidirectional lead screw 202 is rotatably connected between the front and rear inner walls of the mounting frame 201. A slider 203 is threaded onto the bidirectional lead screw 202. The slider 203 is slidably connected between the inner walls of the mounting frame 201. The mounting seat 205 is fixedly connected to the top of the slider 203. The front end of the bidirectional lead screw 202 extends out of the mounting frame 201 and is fixedly connected to a handle 204. The top of the mounting frame 201 is provided with a scale to facilitate observation of the position of the mounting seat 205, thereby adjusting the two sets of mounting seats 205 to the same position.

[0028] A cutting mechanism is provided between the two sets of drive mechanisms. The cutting mechanism includes a mounting plate 301. Multiple sets of circumferentially arranged mounting blocks 302 are installed on the side wall of the mounting plate 301. A cutting wheel 303 is rotatably connected to the end of the mounting block 302. The cutting mechanism also includes a support base 304. The support base 304 is fixedly connected to the top of the base 1. A fixing ring 305 is fixedly connected to the top of the support base 304. An arc-shaped groove is opened on the top of the support base 304. The fixing ring 305 is fixedly connected in the arc-shaped groove. The mounting plate 301 is rotatably connected to the side wall of the fixing ring 305. Multiple sets of circumferentially arranged arc-shaped grooves 306 are opened on the side of the fixing ring 305 near the mounting plate 301. Multiple sets of circumferentially arranged straight grooves 307 are opened on the side of the mounting plate 301 away from the fixing ring 305. A limit rod 308 is slidably connected in the arc-shaped groove 306. The limit rod 308 passes through the straight groove 307 and is fixedly connected to the mounting block 302.

[0029] The cutting mechanism also includes a power assembly for driving the mounting plate 301 to rotate. The power assembly includes a toothed segment 401 fixedly connected to the outer wall of the mounting plate 301. A stepper motor 402 is bolted to the side wall of the support base 304. The stepper motor 402 is a brake motor. A gear 403 is fixedly connected to the output shaft of the stepper motor 402. The gear 403 meshes with the toothed segment 401. When the stepper motor 402 is started, the stepper motor 402 drives the gear 403 to rotate. The gear 403 meshes with the toothed segment 401, thereby driving the toothed segment 401 to rotate the mounting plate 301.

[0030] Working principle: In use, the reinforced polyethylene composite pipe is passed between the two drive wheels 207 between the two sets of drive mechanisms. The stepper motor 402 is started, and the stepper motor 402 drives the gear 403 to rotate. The gear 403 meshes with the tooth segment 401, thereby driving the tooth segment 401 to rotate the mounting plate 301. This causes the limiting rod 308, in cooperation with the arc groove 306 and the straight groove 307, to drive multiple sets of mounting blocks 302 to move synchronously towards the axis of the mounting plate 301, so that the cutting wheel 303 is pressed against the reinforced polyethylene composite pipe. The rotary motor 206 drives the drive wheel 207 to rotate, starting to transport the reinforced polyethylene composite pipe. The cutting wheel 303 cuts the outer layer of the reinforced polyethylene composite pipe, making it easier to peel off the steel wire. The handle 204 drives the bidirectional lead screw 202 to rotate, which drives two sets of sliders 203 to move towards or away from each other. The sliders 203 drive the mounting base 205 to move the rotary motor 206 and the drive wheel 207, making it easy to adapt to reinforced polyethylene composite pipes of different sizes.
