Description

Technical Field

[0001] This invention relates to the field of PVC pipe technology, specifically to an environmentally friendly composite reinforcement device for PVC pipes. Background Technology

[0003] In the PVC pipe production process, the accuracy of raw material pretreatment directly affects the quality of the finished product. To meet the performance requirements of different pipe specifications, raw materials must first be pulverized to ensure stability in subsequent processing. However, traditional production equipment often lacks dedicated material distribution and control components, resulting in insufficient uniformity of raw material pulverization—excessive particle size differences not only affect the material melting and mixing effect but also directly restrict the pipe's structural density, ultimately weakening the product's mechanical strength and making it difficult to meet the demands of high-pressure applications. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly PVC pipe composite reinforcement device to solve the problems mentioned in the background art.

Two crushing rollers are rotatably connected to the inner wall of the pipe raw material processing tank. Two first gears are rotatably connected to one side of the outer wall of the pipe raw material processing tank, and the two first gears are meshed. One side of one of the first gears is provided with a first synchronous pulley. An auger is rotatably connected inside the pipe production machine body.

The third connecting support rod passes through the inner wall of the pipe material distribution tank and is fixedly connected to the center of one side of the third synchronous pulley. The third synchronous pulley is connected to the outer wall of the second synchronous pulley via a second synchronous belt.

[0007] In one example, a second servo motor is provided on one side of the pipe production machine body, and the second servo motor is directly opposite the second synchronous pulley. One end of the second connecting support rod is fixedly connected to the output end of the second servo motor.

[0008] In one example, both sides of the inner wall of the pipe raw material processing tank are fixedly connected to surface impurity scraping plates, and the top of the inner wall of the pipe raw material processing tank is fixedly connected to inclined plates.

[0009] In one example, the pipe diameter reducing mechanism includes an extrusion tube fixedly connected to one side of the pipe production machine body. A first fixing ring is fixedly connected to one side of the outer wall of the extrusion tube. A fixed baffle plate is fixedly connected to the top of the first fixing ring. A lead screw is rotatably connected to one side of the fixed baffle plate. A threaded block is threadedly connected to the outer wall of the lead screw. A movable plate is fixedly connected to the bottom of the threaded block. A first connecting support rod is fixedly connected to both ends of one side of the movable plate. An arc-shaped streamlined guide plate is fixedly connected to the middle of the outer wall of the extrusion tube, and a fixed baffle plate is fixedly connected to the top of the arc-shaped streamlined guide plate. A second fixing ring is slidably connected to the other side of the outer wall of the extrusion tube, and the other end of the first connecting support rod is fixedly connected to one side of the second fixing ring.

[0010] In one example, a plurality of high-strength load-bearing support frames are fixedly connected at equal intervals on one side of the second fixing ring, and a die is fixedly connected to one side of the high-strength load-bearing support frame. A core mold is provided on one side of the extrusion tube, and the core mold is located on one side of the die.

[0011] In one example, a gantry frame is fixedly connected to the outer wall of the first fixed ring, a first helical gear is rotatably connected to the center of the bottom of the gantry frame, a second helical gear is engaged with one side of the first helical gear, and one end of the lead screw passes through one side of the fixed grid baffle and is fixedly connected to the center of one side of the second helical gear.

[0012] In one example, a first servo motor is fixedly connected to the top of the gantry, and the drive shaft of the first helical gear passes through the bottom of the gantry and is fixedly connected to the output end of the first servo motor.

[0013] In one example, an intelligent control panel is provided on one side of the pipe production machine. The surface of the intelligent control panel is provided with a second servo motor switch and a first servo motor switch. The second servo motor is electrically connected to an external power supply through the second servo motor switch and the first servo motor is electrically connected to an external power supply through the first servo motor switch.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. During the production of PVC pipes, the raw materials are first placed inside a raw material distribution trough. A third connecting support rod is located inside the trough, and multiple distribution plates are evenly spaced around the outside of this rod, dividing the trough into several sections. When the PVC raw material needs to be crushed, the rotation of a second servo motor drives a second synchronous pulley. A second synchronous belt is fitted around the second synchronous pulley, and a third synchronous pulley is located at the other end of the second belt. The gear ratio of the third synchronous pulley is the same as that of the second pulley. This ensures that when the second pulley rotates one revolution, the third pulley rotates one revolution as well, causing the internal distribution plates to drop the PVC raw material from the trough to the bottom. Inside the raw material processing tank for pipes, the internal crushing rollers are driven by two first gears. One of the first gears has a first synchronous pulley on one side, and another on the other side. These first and second synchronous pulleys are driven by the same main shaft. A first synchronous belt is fitted around the two pulleys, allowing a second servo motor to drive the material distribution, crushing, and extrusion components simultaneously. This ensures that the amount of PVC pipe material crushed each time is consistent, resulting in uniformly sized PVC pipe fragments. Fragments that are too large or too small will not melt first, while larger fragments require more time and energy to fully melt. This can lead to the presence of both overheated and degraded melt and incompletely plasticized "raw material" within the melt, resulting in uneven melt distribution. This uneven melt distribution directly causes uneven pipe wall thickness, rough inner walls, crystal points or lumps, severely weakening the pipe's mechanical strength. Overheated materials may decompose and turn yellow, producing bubbles and black spots, affecting appearance and performance. This mechanism improves the strength of PVC pipes after production and extends their service life during use.

[0015] 2. An extrusion tube is installed on one side of the pipe production machine. A first fixing ring is provided on the outside of the extrusion tube. A fixed baffle plate is provided on the top of the first fixing ring. A lead screw is provided on one side of the fixed baffle plate. A threaded block is threaded to the outer wall of the lead screw, and a movable plate is provided at the bottom of the threaded block. A first connecting support rod is provided on one side of the movable plate. An arc-shaped streamlined guide plate is provided in the middle of the outer wall of the extrusion tube. A fixed baffle plate is also fixedly connected to the top of the arc-shaped streamlined guide plate. A second fixing ring is slidably connected to one side of the outer wall of the extrusion tube, and the other end of the first connecting support rod is fixedly connected to one side of the second fixing ring. Multiple high-strength load-bearing support frames are fixedly connected to the other side of the second fixed ring, and a die is fixedly connected to the other end of the high-strength load-bearing support frame. The function of the die is to control the distance between it and the core mold, thereby controlling the inner diameter of the produced pipe. In the production process of PVC pipe, the rotation of the screw can drive the first connecting support rod on one side of the movable plate at the bottom of the threaded block to pull the second fixed ring to move, thereby increasing the distance between the die and the core mold on one side of the second fixed ring, so as to control the pipe diameter produced and improve the practicality of the device in use.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-6 The present invention provides a technical solution: an environmentally friendly PVC pipe composite reinforcement device, including a pipe production machine body 1, a uniform feeding and crushing mechanism 3 provided on the top of the pipe production machine body 1, and a pipe diameter changing mechanism 2 provided on one side of the pipe production machine body 1. The uniform feeding and crushing mechanism 3 includes a pipe raw material processing trough 301 fixedly connected to one side of the top of the pipe production machine body 1. Two crushing rollers 302 are rotatably connected to the inner wall of the pipe raw material processing trough 301, and two first gears 303 are rotatably connected to one side of the outer wall of the pipe raw material processing trough 301. The two first gears 303 are meshed together. One side of one of the first gears 303 is provided with a first synchronous pulley 306. An auger 304 is rotatably connected inside the pipe production machine body 1. A second connecting support rod 305 is fixedly connected to one side of the auger 304, and a first synchronous pulley 306 is fixedly connected to one side of the second connecting support rod 305. The two first synchronous pulleys 306 are connected by a first synchronous belt 307. A second synchronous pulley 308 is fixedly connected to one end of the outer wall of the second connecting support rod 305.

[0020] The top of the pipe material processing tank 301 is fixedly connected to the pipe material distribution tank 309. A third connecting support rod 310 is rotatably connected to the center of the inner wall of the pipe material distribution tank 309. Multiple distribution plates 311 are fixedly connected at equal intervals to the outer wall of the third connecting support rod 310. A third synchronous pulley 312 is rotatably connected to one side of the outer wall of the pipe material distribution tank 309. The third connecting support rod 310 passes through the inner wall of the pipe material distribution tank 309 and is fixedly connected to the center of one side of the third synchronous pulley 312. The third synchronous pulley 312 is connected to the outer wall of the second synchronous pulley 308 through the second synchronous belt 313.

[0021] In use, during the production of PVC pipes, the raw materials for PVC pipes are first placed inside the raw material distribution trough 309. A third connecting support rod 310 is located inside the raw material distribution trough 309. Multiple distribution plates 311 are evenly spaced outside the third connecting support rod 310, dividing the raw material distribution trough 309 into multiple sections. When the PVC pipe raw materials need to be crushed, the rotation of the second servo motor 314 drives the second synchronous pulley 308 to rotate. A second synchronous belt 313 is fitted around the second synchronous pulley 308, and a third synchronous pulley 312 is located at the other end of the second synchronous belt 313. The gear ratio of the third synchronous pulley 312 is the same as that of the second synchronous pulley 308. Thus, when the second synchronous pulley 308 rotates 10 times, the third synchronous pulley 312 rotates one time, causing the internal distribution plates 311 to press the raw material within the raw material distribution trough 309... The PVC pipe raw material falls into the pipe raw material processing tank 301 at the bottom. The crushing roller 302 located inside is driven by two first gears 303. One of the first gears 303 is provided with a first synchronous pulley 306 on one side, and another first synchronous pulley 306 is provided on the other side of the second synchronous pulley 308. The first synchronous pulley 306 and the second synchronous pulley 308 are driven by the same main shaft. A first synchronous belt 307 is sleeved on the outside of the two first synchronous pulleys 306. The three components of material distribution, crushing and extrusion can be driven simultaneously by a second servo motor 314. This ensures that the amount of PVC pipe raw material crushed each time is the same, and that the crushed PVC pipe raw material is of large and small size. There will be no excessively large or small fragments. If the fragments are of different sizes, the smaller fragments will melt first, while the larger fragments will require more time and energy to melt completely. This results in the presence of both overheated and degraded melt and incompletely plasticized "raw material" within the molten material. This uneven melt distribution directly leads to uneven pipe wall thickness, rough inner walls, and the appearance of crystal points or lumps, severely weakening the pipe's mechanical strength. Overheated materials may also decompose and turn yellow, producing bubbles and black spots, affecting both appearance and performance. This mechanism improves the strength of PVC pipes after production and extends their service life during use.

[0022] Furthermore, a second servo motor 314 is provided on one side of the pipe production machine body 1, and the second servo motor 314 is directly opposite the second synchronous pulley 308. One end of the second connecting support rod 305 is fixedly connected to the output end of the second servo motor 314. The second servo motor 314 located on one side of the pipe production machine body 1 is used to drive the auger 304, crushing roller 302 and material distribution plate 311 simultaneously, so that the internal operation is more synchronized during use.

[0023] Furthermore, both sides of the inner wall of the pipe material processing tank 301 are fixedly connected with surface impurity scraping plates 315, and the top of the inner wall of the pipe material processing tank 301 is fixedly connected with inclined plates 316. Inside the pipe material processing tank 301, there is a surface impurity scraping plate 315 and an inclined plate 316. The surface impurity scraping plate 315 is used to scrape off the PVC pipe material adhering to the outside of the crushing roller 302. The inclined plate 316 is used to allow the PVC pipe material that has fallen from the pipe material distribution tank 309 into the pipe material processing tank 301 to smoothly enter the crushing roller 302.

[0024] Furthermore, the pipe diameter changing mechanism 2 includes an extrusion pipe 201 fixedly connected to one side of the pipe production machine body 1.

An arc-shaped streamlined guide plate 207 is fixedly connected to the middle of the outer wall of the extrusion pipe 201. A fixed baffle plate 203 is fixedly connected to the top of the arc-shaped streamlined guide plate 207. A second fixing ring 209 is slidably connected to the other side of the outer wall of the extrusion pipe 201. The other end of the first connecting support rod 208 is fixedly connected to one side of the second fixing ring 209.

[0025] Multiple high-strength load-bearing support frames 210 are fixedly connected at equal intervals on one side of the second fixed ring 209. A die 211 is fixedly connected to one side of the high-strength load-bearing support frame 210. A core mold 212 is provided on one side of the extrusion tube 201, and the core mold 212 is located on one side of the die 211.

[0026] In use, an extrusion tube 201 is installed on one side of the pipe production machine body 1. A first fixing ring 202 is provided on the outside of the extrusion tube 201. A fixed baffle plate 203 is provided on the top of the first fixing ring 202. A screw 204 is provided on one side of the fixed baffle plate 203.

A first connecting support rod 208 is provided on one side of the movable plate 206. An arc-shaped streamlined guide plate 207 is provided in the middle of the outer wall of the extrusion tube 201. A fixed baffle plate 203 is also fixedly connected to the top of the arc-shaped streamlined guide plate 207. A second fixing ring 209 is slidably connected to one side of the outer wall of the extrusion tube 201. The other end of the first connecting support rod 208 is connected to the second fixed ring 209. One side of the ring 209 is fixedly connected, and multiple high-strength load-bearing support frames 210 are fixedly connected to the other side of the second fixed ring 209. A die 211 is fixedly connected to the other end of the high-strength load-bearing support frame 210. The function of the die 211 is to control the distance between it and the core mold 212, thereby controlling the inner diameter of the produced pipe. In the process of producing PVC pipe, the rotation of the screw 204 can drive the first connecting support rod 208 on one side of the movable plate 206 at the bottom of the threaded block 205 to pull the second fixed ring 209 to move. This can then increase the distance between the die 211 and the core mold 212 on one side of the second fixed ring 209, thereby controlling the diameter of the produced pipe and improving the practicality of the device in use.

[0027] Furthermore, a gantry 213 is fixedly connected to the outer wall of the first fixed ring 202, and a first helical gear 214 is rotatably connected to the center of the bottom of the gantry 213. A second helical gear 215 is engaged with one side of the first helical gear 214, and one end of the lead screw 204 passes through one side of the fixed grid baffle 203 and is fixedly connected to the center of one side of the second helical gear 215.

[0029] The gantry 213 located at the top of the first fixed ring 202 is used to support the first helical gear 214 and the second helical gear 215, so that the first helical gear 214 can drive the second helical gear 215 to rotate simultaneously during the rotation of the first helical gear 214, which in turn can drive the lead screw 204 to rotate, so as to move the die 211. The first servo motor 216 located at the top of the gantry 213 is used to drive the first helical gear 214 to rotate.
