Description

Technical Field

[0001] This invention relates to the field of MPP power pipe processing technology, specifically to a processing fixture and processing method for MPP power pipes. Background Technology

[0002] MPP pipe, also known as MPP power cable protection pipe, is divided into open-cut and trenchless types. Trenchless MPP pipe is also called MPP jacking pipe or drag pipe. MPP pipe uses modified polypropylene as the main raw material. It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for medium and low voltage power transmission cable ducts below 10KV.

[0003] In practical applications, MPP pipes are typically wrapped with a layer of fiberglass tape to increase their strength and lifespan. However, the manufacturing process generally involves extrusion molding and subsequent cooling. During extrusion, the MPP pipe moves horizontally, making it difficult to wrap the tape around its surface. Therefore, this paper proposes a processing fixture and method for MPP power pipes.

[0010] As a further aspect of the present invention: the end of the cutting blade is provided with a rotating cutting blade.

[0011] As a further aspect of the present invention, an extrusion wheel is provided at the end of the sliding plate.

[0012] As a further aspect of the present invention: the replacement mechanism includes a second cylinder, a first sliding plate is fixedly installed on the piston rod of the second cylinder, the bottom of the first sliding plate is connected to a bidirectional cylinder through a cylinder telescopic rod, and U-shaped clamps are installed at both ends of the bidirectional cylinder, the U-shaped clamps being adapted to the notch groove and the sliding groove.

[0013] As a further embodiment of the present invention: the hot pressing mechanism includes a cylinder three, a sliding plate two is fixedly installed on the piston rod of the cylinder three, telescopic rods are symmetrically installed on both sides of the bottom of the sliding plate two, lifting plates are fixedly installed on the telescopic rods, a fixed shaft and a rotating shaft are arranged vertically between the two lifting plates, a cylinder four is fixedly installed at the bottom center of the sliding plate two, a connecting plate is fixedly installed on the piston rod of the cylinder four, the connecting plate is sleeved on the fixed shaft and the rotating shaft, torsion springs are provided at both ends of the connecting plate and on the fixed shaft, an inclined plate is provided at the bottom of the connecting plate, and a hot pressing plate is fixedly installed on the inclined plate.

[0014] As a further aspect of the present invention: a storage seat is provided on the top of the base, and a storage groove is provided on the top of the storage seat, and a plurality of compression balls are provided inside the storage groove.

[0015] As a further aspect of the present invention: a method for processing an MPP power pipe, comprising the following steps:

[0016] Step 1: The extruder extrudes the MPP power pipe into shape, then cools and shapes it. It passes through the left-end traction mechanism. When one end of the MPP power pipe moves to the support seat, the traction mechanism is activated. The cutting blade contacts the surface of the MPP power pipe, then the cutting blade rotates and moves inward to cut it off. Finally, it continues to move until the extrusion wheel clamps the MPP power pipe and drives the left-end traction mechanism to rotate and move horizontally, thereby moving the cut MPP power pipe.

[0017] Step 2: When the cut MPP power tube moves to the bottom of the winding mechanism, the winding mechanism wraps a layer of fiberglass tape around the MPP power tube and heat-presses it onto the surface of the MPP power tube through the hot pressing mechanism. When the MPP power tube passes through the storage seat, the left traction mechanism releases and resets, and Step 1 is repeated. At this time, the right traction mechanism will clamp the other end of the MPP power tube and continue to rotate and move until the winding is completed.

[0018] The beneficial effects of this invention are:

[0019] This invention, through the design of a traction mechanism, facilitates integration with an extruder to form a complete production line. After the MPP power pipe is cut, it is easily transported by rotation via the traction mechanism. Combined with a winding mechanism and a hot-pressing mechanism, fiberglass tape is wound around its surface, and finally, it is placed on a support for storage. The entire process is highly automated and widely applicable. It solves the problem that existing extruders produce power pipes that are single-piece tubes that can only move horizontally, making it difficult to wind fiberglass tape around their surface.

[0020] This invention uses multiple rubber extrusion balls inside the storage tank. During the rotation and movement of the MPP power pipe, the residual heat of the traction hot pressing is used to extrude and mold the fiberglass tape wrapped on its surface again through the rubber extrusion balls, which is convenient to use and has a better molding effect.

[0032] 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.

[0033] Example 1

[0034] Please see Figure 1-9 As shown, this invention is a processing fixture for MPP power pipes, including a base 1. Two sets of traction mechanisms 2 are symmetrically installed on the top of the base 1. The traction mechanisms 2 can be moved by a cylinder, motor, lead screw, or other structure. The traction mechanism 2 on the right side does not have a cutting blade 215 structure and mainly serves to clamp and pull. A winding mechanism 3 is arranged between the traction mechanisms 2. A support seat 11 is arranged below the winding mechanism 3. A replacement mechanism 4 is arranged above the winding mechanism 3. A hot pressing mechanism 5 is arranged on one side of the replacement mechanism 4. The winding mechanism 3 includes a first support seat 31. A first cylinder 32 is fixedly installed on the first support seat 31. A sliding seat 33 is fixedly installed on the piston rod of the first cylinder 32. The winding mechanism 3 also includes a second support seat 35. A winding reel 34 is arranged between the second support seat 35 and the sliding seat 33.

[0035] The cut MPP power pipe is rotated and moved by the traction mechanism 2. During the movement, a layer of fiberglass is wound around the surface of the MPP power pipe in conjunction with the winding mechanism 3. The fiberglass is then manually cut to improve its strength. The fiberglass layer is then hot-pressed onto the surface of the MPP power pipe by the hot-pressing mechanism 5 to make the winding tighter.

[0036] The unwinding reel 34 includes a first extrusion reel 341 and a second extrusion reel 342. Both the first extrusion reel 341 and the second extrusion reel 342 are provided with notches 343, and a support shaft 344 is fixedly installed at the outer center of both the first extrusion reel 341 and the second extrusion reel 342. An inner sleeve 352 is fixedly installed on the inner side of the first extrusion reel 341. Multiple sliding grooves 348 adapted to the notches 343 are provided on the outer circumferential surface of the inner sleeve 352. An outer sleeve 354 is provided on the second extrusion reel 342, and the outer sleeve 354 is inserted into the inner sleeve 352. The replacement mechanism 4 includes a second cylinder 41. A sliding plate 42 is fixedly installed on the piston rod of the second cylinder 41. The bottom of the sliding plate 42 is connected to a bidirectional cylinder 43 through a cylinder telescopic rod. Both ends of the bidirectional cylinder 43 are equipped with U-shaped clamping plates 44. The U-shaped clamping plates 44 are adapted to the notch groove 343 and the sliding groove 348, so that when replacing the fiberglass tape roll, the clamping and fixing of the first extrusion plate 341, the second extrusion plate 342, the inner sleeve 352 and the outer sleeve 354 are not affected.

[0037] Start cylinder 41 and cylinder extension rod to adjust the position of U-shaped clamp 44. Then start bidirectional cylinder 43 to separate the two U-shaped clamps 44. The U-shaped clamps 44 then hold the fiberglass tape roll and move it between extrusion disc 341 and extrusion disc 342. Then start cylinder 32 to push extrusion disc 341 to move, so that the inner sleeve 352 is inserted into the outer sleeve 354, thus holding the fiberglass tape roll. Then release and remove the replacement mechanism 4. This structure facilitates the disassembly and replacement of fiberglass tape rolls. The depth of the inner sleeve 352 inserted into the outer sleeve 354 can be adjusted by the extrusion discs 341 and 342 to accommodate fiberglass tape rolls of different widths. This structure can automatically replace fiberglass tape rolls of different widths, with a high degree of automation.

[0038] The inner sleeve 352 has a rotating shaft 347 fixedly installed inside, and a U-shaped adjusting shaft 345 is rotatably connected to the rotating shaft 347. An L-shaped swing block 353 is provided at one end of the U-shaped adjusting shaft 345. The end of the swing block 353 is arc-shaped. An arc-shaped placement groove 346 adapted to the U-shaped adjusting shaft 345 is opened on the outer surface of the inner sleeve 352. A spring 349 is fixedly installed inside the inner sleeve 352. A pressure block 350 is fixedly installed on the spring 349. Both the pressure block 350 and the inner sleeve 352 have through grooves 351. The outer sleeve 354 has a plug-in plate 355 adapted to the swing block 353 inside. The end of the plug-in plate 355 is inclined. The inner sleeve 352 also has a groove adapted to the plug-in plate 355. The outer sleeve 354 also has a mortise block 356 adapted to the through groove 351 inside. When the inner sleeve 352 and the outer sleeve 354 are inserted, the insertion plate 355 will contact the swing block 353, thereby pushing the U-shaped adjusting shaft 345 to rotate and contact the fiberglass tape roll from the inside; at the same time, the collapsing block 356 will contact the spring 349 for cushioning.

[0039] Example 2

[0040] Based on Example 1, see [link / reference] Figure 2-4As shown, the traction mechanism 2 includes a mounting plate 21 that slides on the base 1. A motor 22 is fixedly mounted on the mounting plate 21. A gear is provided on the output shaft of the motor 22. A rotating tube 23 is also rotatably connected to the mounting plate 21. A gear 24 is sleeved on the rotating tube 23. The gear and gear 24 are connected by a chain. The rotating tube 23 passes through the mounting plate 21 and is fixedly connected to a support plate 25. A central hole 214 is provided at the center of the support plate 25. A second motor 21 is fixedly mounted on the side of the support plate 25 away from the mounting plate 21. 1. The output shaft of the second motor 211 passes through the support plate 25 and connects to the third gear 210. A second gear 28 is sleeved on the rotating tube 23. The third gear 210 is connected to the second gear 28 via a chain. A rotating disk 26 is fixedly installed on the side of the second gear 28 away from the mounting plate 21. The rotating disk 26 has three equally spaced arc-shaped grooves 27. A pin 29 is fitted inside each arc-shaped groove 27. The pin 29 passes through a pin hole 216 on the support plate 25 and connects to a sliding plate 212. A cutting blade 215 is fixedly installed on the sliding plate 212. A rotating cutter 217 is provided at the end of the cutting blade 215, which, in conjunction with the cutting blade 215, improves the cutting effect. A pressing wheel 213 is provided at the end of the sliding plate 212 to guide the cutting process and, after cutting, to press and fix it.

[0041] The MPP power pipe passes through the traction mechanism 2. Motor 211 is started, driving gear 3 210 to rotate. This, in turn, drives gear 28 via a chain. Gear 28 rotates, causing the rotating disk 26 to rotate. During the rotation of the rotating disk 26, the pin 29, through the arc groove 27 and pin hole 216, synchronously pushes the sliding plate 212 to move, causing the cutting blade 215 to contact the MPP power pipe. Then, motor 22 is started, driving the rotating tube 23, which in turn drives the entire support disk 25 to rotate. The cutting blade 215 cuts the pipe. After cutting, the sliding plate 212 continues to slide, and the extrusion wheel 213 clamps the MPP power pipe. The entire traction mechanism 2 is moved by a cylinder, motor, or lead screw. This structure is suitable for MPP power pipes of different diameters.

[0042] The hot pressing mechanism 5 includes a cylinder 3 51, a sliding plate 2 52 fixedly mounted on the piston rod of the cylinder 3 51, telescopic rods 53 symmetrically mounted on both sides of the bottom of the sliding plate 2 52, lifting plates 54 fixedly mounted on the telescopic rods 53, a fixed shaft 56 and a rotating shaft 510 arranged vertically between the two lifting plates 54, a cylinder 4 55 fixedly mounted at the bottom center of the sliding plate 2 52, a connecting plate 58 fixedly mounted on the piston rod of the cylinder 4 55, the connecting plate 58 sleeved on the fixed shaft 56 and the rotating shaft 510, torsion springs 57 arranged at both ends of the connecting plate 58 and located on the fixed shaft 56, an inclined plate 59 arranged at the bottom of the connecting plate 58, and a hot pressing plate 511 fixedly mounted on the inclined plate 59.

[0043] Start cylinder 3 51 to move, thereby adjusting the movement of hot press plate 511. Then start cylinder 4 55 to push connecting plate 58 to rotate. Then, through inclined plate 59, hot press plate 511 is driven to contact the fiberglass tape wrapped on MPP power pipe for hot pressing, which facilitates hot pressing and makes it more aesthetically pleasing.

[0044] The base 1 has a storage seat 6 on its top, which supports the MPP power tube during movement. The storage seat 6 can move back and forth via gears and racks, facilitating the storage of MPP power tubes. The top of the storage seat 6 has a storage groove 61 for guiding and storing the MPP power tubes. The storage groove 61 contains multiple rubber extrusion balls 62. During the rotation and movement of the MPP power tube, the residual heat from the traction and hot pressing process further extrudes and shapes the fiberglass tape wrapped around its surface using the rubber extrusion balls 62, improving usability and forming quality. Heating can also be achieved inside the storage seat 6. When an MPP power tube is pulled onto the storage seat 6 by the traction mechanism 2 at the right end, the traction mechanism 2 releases it, causing the storage seat 6 to move to a different position for the next MPP power tube. The operation is convenient.

[0045] Example 3

[0046] See Figure 1-9 As shown, a method for processing an MPP power pipe includes the following steps:

[0047] Step 1: The extruder extrudes the MPP power pipe into shape, then cools and solidifies it. It passes through the left-end traction mechanism 2. Motor 211 is started, driving gear 3 210 to rotate, which in turn drives gear 28 via a chain. Gear 28 rotates, causing the rotating disk 26 to rotate. During the rotation of the rotating disk 26, the pin 29, through the arc-shaped groove 27 and pin hole 216, synchronously pushes the sliding plate 212 to move, thus causing the cutting blade 215 to contact the MPP power pipe. Then, motor 22 is started, driving the rotating tube 23, which in turn drives the entire support disk 25 to rotate. The cutting blade 215 cuts the pipe. After cutting, the sliding plate 212 continues to slide, and the extrusion wheel 213 clamps the MPP power pipe. The left-end traction mechanism 2 is driven by a cylinder, motor, or lead screw to rotate and move horizontally, thereby causing the cut MPP power pipe to rotate and move.

[0048] Step 2: When the cut MPP power tube moves to the bottom of the winding mechanism 3, the winding mechanism 3 winds a layer of fiberglass tape around the MPP power tube and heat-presses it onto the surface of the MPP power tube through the hot pressing mechanism 5. When the MPP power tube passes through the storage seat 6, the left end traction mechanism 2 is released and reset, and Step 1 is repeated. At this time, the right end traction mechanism 2 will clamp the other end of the MPP power tube and continue to rotate and move until the winding is completed. Finally, the MPP power tube is placed in the storage seat 6 for storage.

[0049] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

At this time, the right end traction mechanism (2) will clamp the other end of the MPP power tube and continue to rotate and move until the winding is completed.
