Description

Technical Field

[0001] This invention relates to the field of electrofusion pipe fitting processing technology, specifically to an electrofusion pipe fitting processing equipment and method. Background Technology

[0002] Electrofusion fittings are plastic (polyethylene) pipe fittings that achieve connection by melting the pipes using the temperature generated by an electric current. Developed specifically for its vector structure system characteristics, it boasts powerful functions including plastic load-bearing capacity, variable flexibility, reliable electro-heating welding, and socket positioning, making it suitable for connecting PE-RT and PE piping systems.

[0003] Electrofusion fittings use pure copper wire as the heat source, with a diameter of 0.6mm-0.8mm. Pure copper wire possesses advantages such as high temperature resistance, stable resistance, stable heat generation, aging resistance, and oxidation resistance, preventing rust. Therefore, fittings of the same specification exhibit consistent heat generation during electrofusion, resulting in stable electrofusion quality and eliminating the risk of open circuits. In manufacturing electrofusion fittings, pure copper wire is wound around a metal core rod in the mold or a pre-fabricated polyethylene sheath, and then injected into the injection mold to form an electrofusion fitting with embedded heating wire. The mold core refers to the mold portion used to form the internal shape of the product. During injection molding, molten plastic is injected into the mold system as a high-pressure fluid through a nozzle, filling the mold cavity via the main runner, runner, and gate. After filling, injection stops, pressure is maintained, the cooling system begins operation, the mold opens, and the product is removed.

[0004] In existing electrofusion pipe fitting processing, after injection molding, a robotic arm places the pipe fitting and mold core together on a conveyor belt for air cooling. However, since the air cooling outlets are located on both sides of the pipe fitting and mold core, and the pipe fitting and mold core are placed on a rack, the bottom side of the pipe fitting has less contact with the cold air, resulting in uneven cooling and poor air cooling effect with a long cooling time. Therefore, this does not meet the current requirements. To address this, we propose an electrofusion pipe fitting processing equipment and method. Summary of the Invention

[0005] This invention provides an electrofusion pipe fitting processing equipment and method, which features the beneficial effects of flipping and rotating the pipe fitting and mold core during the conveying process, thereby increasing the contact area between the pipe fitting and the cold air and improving the cooling effect. This solves the problem mentioned in the background art that in the existing electrofusion pipe fitting processing, after injection molding, the pipe fitting and mold core are placed together on a conveyor belt by a robot to receive air cooling. Since the air cooling outlet is located on both sides of the pipe fitting and mold core, and the pipe fitting and mold core are placed on a rack, the bottom side of the pipe fitting has less contact with the cold air, resulting in uneven cooling, poor air cooling effect, and long cooling time.

[0010] As an optional solution for the electrofusion pipe fitting processing equipment of the present invention, wherein: the angle track and the clamping track in the loading area are straight tracks that are parallel to each other; the angle track in the fixed air cooling area remains straight; the clamping track moves closer to the direction of the angle track; the angle track in the rotating air cooling area moves closer to the direction of the clamping track; the clamping track and the angle track remain parallel; and the angle track and the clamping track in the unloading area return to the straight position in the loading area.

[0011] As an optional solution for the electrofusion pipe fitting processing equipment of the present invention, wherein: the spacing of the self-adjusting clamping claws in the feeding area is relatively large, the spacing of the self-adjusting clamping claws at the junction of the feeding area and the fixed air cooling area becomes smaller, the self-adjusting clamping claws in the fixed air cooling area and the rotating air cooling area maintain a clamping state, the spacing of the self-adjusting clamping claws in the unloading area increases back to the spacing in the feeding area, and the self-adjusting clamping claws in the rotating air cooling area rotate to a horizontally arranged position.

[0012] As an optional solution for the electrofusion pipe fitting processing equipment of the present invention, wherein: both the fixed clamping bar and the movable clamping bar are configured as arc-shaped clamping bars, and both the fixed clamping bar and the movable clamping bar have an arc-shaped groove in the middle, and a plurality of driven wheels are rotatably installed in the arc-shaped groove; a drive wheel is rotatably installed on the outer side of the fixed clamping bar, and the drive wheel is connected to the driven wheel in a transmission connection; a protrusion is installed on the side of the track table, and the drive wheel rolls and fits against the protrusion.

[0015] As an optional solution for the electrofusion pipe fitting processing equipment described in this invention, the elastic airbag is configured as a rubber airbag with an internal spring, and the air guide tube is configured as a rubber hose.

[0016] This solution also proposes a method for using electrofusion fitting processing equipment, including the following specific steps:

[0017] S1. Turn on the conveyor belt and fan, and use the robot to place the undemolded mold core on the movable clamping seat located at the end of the feeding area. One end of the mold core is located between the self-adjusting clamping claws, and the other end of the mold core is located on the fixed placement frame.

[0018] S2. The robotic arm removes the mold core from the unloading area, separating the mold core from the self-adjusting gripper and the fixed placement frame;

[0019] S3. Manually demold the mold core and remove the processed electrofusion fitting.

[0020] The present invention has the following beneficial effects:

[0021] 1. This electrofusion fitting processing equipment and method, through the setting of a conveyor belt and a fan, can air-cool the electrofusion fitting and the mold core during the transportation of the mold core carrying the electrofusion fitting. The self-adjusting clamping claw can clamp the mold core placed on the fixed placement frame. Through the setting of the track table, the rack extends according to the change of the angle track, so that the rack drives the gear column to rotate through meshing, thereby causing the rotating shaft to drive the mounting base and the self-adjusting clamping claw to rotate, so that the mold core leaves the fixed placement frame and is rotated 90 degrees by the self-adjusting clamping claw. This changes the contact surface between the mold core and the cold air, changes the position of contact with the cold air, solves the problem that the bottom side of the mold core is difficult to contact with the cold air in the existing method, thereby increasing the contact area for air cooling and improving the cooling effect of the electrofusion fitting.

[0022] 2. The electrofusion fitting processing equipment and method, by opening an air cavity inside the rack and installing an elastic air bladder in the slide groove, when the connecting rod moves with the clamping track, the connecting rod will move relative to the rack, so that the gas in the air cavity enters the elastic air bladder through the air guide pipe, causing the elastic air bladder to expand. The push plate drives the moving plate to move, so that the movable clamping bar approaches the fixed clamping bar, realizing the automatic clamping of the self-adjusting clamping claw. Thus, when cooling the electrofusion fitting and the mold core, there is no need for manual operation of the self-adjusting clamping claw. The self-adjusting clamping claw can clamp the fixed mold core, so that the mold core will not fall off when the self-adjusting clamping claw flips, but will flip with the self-adjusting clamping claw.

[0023] 3. The electrofusion pipe fitting processing equipment and method, by rotatably mounting a drive wheel and multiple driven wheels on a self-adjusting clamping claw, and through the contact between the convex strip and the drive wheel, after the self-adjusting clamping claw flips with the mold core, the drive wheel on the outer side of the self-adjusting clamping claw contacts the convex strip, causing the drive wheel to drive the driven wheel located on the inner side of the self-adjusting clamping claw to rotate through the transmission gear and drive gear. In turn, the friction between the driven wheel and the mold core drives the mold core to rotate, realizing 360° contact between the mold core and the cold air, further improving the air cooling effect; and through the change of the angle track, when the material is about to be unloaded, the rack drives the gear column to rotate and reset, so that the self-adjusting clamping claw automatically resets, which facilitates the unloading of the electrofusion pipe fitting and the mold core by the robot arm.

[0034] 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.

[0035] Example 1: This example aims to address the problem in existing electrofusion pipe processing where, after injection molding, a robotic arm places the pipe and mold core together on a conveyor belt for air cooling. Because the air cooling outlets are located on both sides of the pipe and mold core, and the pipe and mold core are placed on a rack, the bottom side of the pipe receives less contact with the cold air, resulting in uneven cooling, poor cooling effect, and prolonged cooling time. Please refer to [link to relevant documentation]. Figures 1-9 An electrofusion pipe fitting processing equipment includes a frame 110 and a conveyor belt 120. The conveyor belt 120 is mounted on the frame 110. The upper surface of the conveyor belt 120 is provided with four working areas in sequence: a feeding area 10, a fixed air-cooling area 20, a rotary air-cooling area 30, and a discharging area 40. Several mounting plates 210 are equidistantly mounted on the surface of the conveyor belt 120. The mounting plates 210 are provided with a fixed placement frame 220 and a movable clamping seat 300 for clamping and fixing the electrofusion pipe fitting and the mold core. Two air-cooling plates 130 are mounted on the frame 110. Several fans 140 for cooling the electrofusion pipe fitting and the mold core are symmetrically mounted on the air-cooling plates 130. A track table 410 for adjusting the state of the movable clamping seat 300 is provided on the side of the frame 110. The track table 410 maintains a distance from the surface of the conveyor belt 120.

[0036] In specific configuration, the transmission track 120 is configured as a track transmission belt driven by a servo motor, and the mounting plate 210 is configured as a rectangular plate, which is detachably mounted on the track plates of the transmission track 120 by bolts. See Figure 3 The fixed placement frame 220 is configured as a bracket vertically welded to one end of the mounting plate 210. The fixed placement frame 220 is configured as an upward Y-shaped bracket. The mold core with electrofusion fittings is placed on the fixed placement frame 220, and the fixed placement frame 220 provides support for it.

[0037] The movable clamping seat 300 includes a base 310 fixedly mounted on the mounting plate 210, a rotating shaft 320 rotatably mounted on the base 310, a mounting seat 330 fixedly mounted on the rotating shaft 320, and a self-adjusting clamping claw 340 provided on the mounting seat 330. The self-adjusting clamping claw 340 is divided into a fixed clamping bar 341 fixedly mounted on the mounting seat 330 and a movable clamping bar 342 slidably mounted. A gear column 350 is installed at the end of the rotating shaft 320. An angled track 430 is provided on the track platform 410. A rack 360 is slidably inserted into the angled track 430 and meshes with the gear column 350.

[0038] See Figure 2 and Figure 6 A support slide bar 361 is installed on the side of the mounting plate 210. The rack 360 is perpendicular to the support slide bar 361 and is slidably engaged. During the operation of the transmission track 120, the rack 360 is slidably engaged with the angle track 430 and extends as the angle track 430 changes, causing the rack 360 to drive the gear column 350 to rotate through meshing. This causes the rotating shaft 320 to drive the mounting base 330 and the self-adjusting clamping claw 340 to rotate, causing the mold core to leave the fixed placement frame 220 and be clamped by the self-adjusting clamping claw 340 and rotated 90 degrees.

[0039] In this embodiment: By using the conveyor belt 120 and fan 140, the electrofusion tube and mold core can be air-cooled during transportation. The self-adjusting clamping claw 340 can clamp the mold core placed on the fixed placement frame 220. With the track platform 410, the rack 360 extends as the angle track 430 changes, causing the rack 360 to mesh and drive the gear column 350 to rotate. This causes the rotating shaft 320 to drive the mounting base 330 and the self-adjusting clamping claw 340 to rotate, causing the mold core to leave the fixed placement frame 220. The mold core is clamped by the self-adjusting clamping claw 340 and rotated 90 degrees, changing the contact surface between the mold core and the cold air. This changes the position of contact with the cold air, solving the problem that the bottom side of the existing mold core is difficult to contact with the cold air, thereby increasing the contact area for air cooling and improving the cooling effect of the electrofusion tube.

[0040] This embodiment also discloses a method for using equipment for processing electrofusion pipe fittings, including the following specific steps:

[0041] S1. Turn on the conveyor belt 120 and fan 140, and use the robot to place the mold core that has not been demolded on the movable clamping seat 300 located at the end of the feeding area 10. One end of the mold core is located between the self-adjusting clamping claws 340, and the other end of the mold core is located on the fixed placement frame 220.

[0042] S2. The mold core located in the unloading area 40 is removed by a robotic arm, and the mold core is separated from the self-adjusting gripper 340 and the fixed placement rack 220;

[0043] S3. Manually demold the mold core and remove the processed electrofusion fitting.

[0044] In practice, pure copper wire is wound around a metal core rod of the mold or a prefabricated polyethylene sheath, and then the core is injected into the injection mold to form an electrofusion fitting with embedded heating wire. After the mold core with the electrofusion fitting is removed, it is placed on the conveyor belt 120 by a robotic arm, and after air cooling, the mold core is demolded.

[0045] Example 2 aims to address the issue that if the clamping is not secure enough, the electrofusion fitting and mold core may fall off after the self-adjusting clamping claw 340 rotates. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figures 1-9 The track platform 410 has an extension platform 420 installed on its side. The extension platform 420 has a clamping track 440. The rack 360 has a connecting rod 370 inserted into its side. The other end of the connecting rod 370 is in sliding engagement with the clamping track 440. The connecting rod 370 is in transmission engagement with the fixed clamping bar 341.

[0046] The mounting base 330 has a sliding groove 331. A movable plate 343 is integrally connected to the bottom end of the movable clamping bar 342. The movable plate 343 engages with the sliding groove 331. An elastic airbag 332 is installed in the sliding groove 331. A push plate 333 is glued to the end of the elastic airbag 332, and the other side of the push plate 333 is fixedly connected to the movable plate 343. The push plate 333 and the movable plate 343 can be connected by bolts or glue. Moving the push plate 333 will move the movable plate 343, thus adjusting the distance between the movable clamping bar 342 and the fixed clamping bar 341, thereby adjusting the clamping force.

[0047] See Figure 9 The rack 360 has an internal air chamber 372, and an air guide tube 373 connects the air chamber 372 and the elastic air bladder 332. A piston plate 371 is inserted into the end of the connecting rod 370 that is connected to the rack 360, and the piston plate 371 slides against the inner wall of the air chamber 372. Specifically, the elastic air bladder 332 is a rubber air bladder with an internal spring, and the air guide tube 373 is a rubber hose.

[0048] See Figure 6 In the feeding area 10, the angle track 430 and the clamping track 440 are straight tracks that are parallel to each other. In the fixed air-cooling area 20, the angle track 430 remains straight, and the clamping track 440 moves closer to the direction of the angle track 430. In the rotating air-cooling area 30, the angle track 430 moves closer to the direction of the clamping track 440, and the clamping track 440 and the angle track 430 remain parallel. In the unloading area 40, the angle track 430 and the clamping track 440 return to the straight position in the feeding area 10.

[0049] The spacing between the self-adjusting clamping claws 340 in the feeding area 10 is relatively large. The spacing between the self-adjusting clamping claws 340 at the junction of the feeding area 10 and the fixed air-cooling area 20 becomes smaller. The self-adjusting clamping claws 340 in the fixed air-cooling area 20 and the rotating air-cooling area 30 maintain a clamping state. The spacing between the self-adjusting clamping claws 340 in the unloading area 40 increases and returns to the spacing in the feeding area 10. The self-adjusting clamping claws 340 in the rotating air-cooling area 30 rotate to a horizontal setting.

[0050] In this embodiment: by opening an air cavity 372 inside the rack 360 and installing an elastic airbag 332 in the slide groove 331, when the connecting rod 370 moves with the clamping track 440, the connecting rod 370 will move relative to the rack 360, so that the gas in the air cavity 372 enters the elastic airbag 332 through the air guide pipe 373, causing the elastic airbag 332 to expand. The push plate 333 drives the moving plate 343 to move, so that the movable clamping bar 342 approaches the fixed clamping bar 341, realizing the automatic clamping of the self-adjusting clamping claw 340. Thus, when cooling the electrofusion fitting and the mold core, there is no need to manually operate the self-adjusting clamping claw 340. The self-adjusting clamping claw 340 can clamp the fixed mold core, so that the mold core will not fall off when the self-adjusting clamping claw 340 flips, but will flip with the self-adjusting clamping claw 340.

[0051] Example 3 aims to further improve the air-cooling effect. This example is an improvement on Example 2. For details, please refer to Example 2. Figures 1-9 Both the fixed clamping bar 341 and the movable clamping bar 342 are arc-shaped clamping bars. Both the fixed clamping bar 341 and the movable clamping bar 342 have an arc-shaped groove 650 in the middle. Several passive wheels 620 are rotatably installed in the arc-shaped groove 650. A drive wheel 610 is rotatably installed on the outer side of the fixed clamping bar 341. The drive wheel 610 is connected to the passive wheel 620 for transmission. A protrusion 510 is installed on the side of the track platform 410. The drive wheel 610 rolls and fits against the protrusion 510.

[0052] The protrusion 510 is located in the rotating air-cooling zone 30, and the two ends of the protrusion 510 are connected to the surface of the track table 410 by connecting inclined surfaces 520.

[0053] Both the drive wheel 610 and the driven wheel 620 are rubber wheels. The drive gear 640 is coaxially fixedly mounted on the bottom side of the drive wheel 610. The drive gear 630 is coaxially fixedly mounted on the driven wheel 620 closest to the drive wheel 610. The drive gear 640 and the drive gear 630 mesh with each other, and the drive gear 640 is clearance-fitted with the convex strip 510.

[0054] In this embodiment: by rotatably mounting a drive wheel 610 and multiple driven wheels 620 on the self-adjusting gripper 340, and through the contact between the protrusion 510 and the drive wheel 610, after the self-adjusting gripper 340 rotates with the mold core, the drive wheel 610 on the outside of the self-adjusting gripper 340 contacts the protrusion 510, so that the drive wheel 610 drives the driven wheel 620 located on the inside of the self-adjusting gripper 340 to rotate through the transmission gear 630 and the drive gear 640. Thus, the friction between the driven wheel 620 and the mold core drives the mold core to rotate, realizing that the mold core is in contact with the cold air 360°, further improving the air cooling effect; and through the change of the angle track 430, when the material is about to be unloaded, the rack 360 drives the gear column 350 to rotate and reset, so that the self-adjusting gripper 340 automatically resets, which facilitates the unloading of the electrofusion fitting and the mold core by the robot arm.
