Description

Technical Field

[0001] This invention relates to the field of electrofusion tube processing technology, specifically to an automated post-firing equipment and method for electrofusion tube fittings. Background Technology

[0002] Electrofusion fittings are plastic (polyethylene) pipe fittings that can be connected by melting through the temperature generated by an electric current. The processing of electrofusion fittings requires several spirally distributed copper wires to be laid inside the plastic pipe fittings. However, the processing of electrofusion fittings is divided into two types: front wire laying and back wire laying. Front wire laying is the laying of wires during the injection molding process of the pipe fittings.

[0003] Post-threading involves creating a spiral groove in the inner hole of the pipe by rotating the pipe itself, and then pressing the thread into the groove through a tool on one side.

[0004] Currently available electrofusion tube post-wire laying equipment requires manual intervention during the post-wire laying process. One end of the copper wire is first pulled out from the metal wire outlet of the electrofusion tube body, which is inconvenient for automated post-wire laying operations. Summary of the Invention

[0016] This invention also discloses a method for using an automated wire-laying device for electrofusion fittings, which includes the following steps:

[0017] S1. Preparation: Before the post-weaving process, the injection molding machine is used to form the tubes. The tubes are then removed by a robotic arm and allowed to cool naturally. Natural cooling results in good shrinkage stability. The tubes are then transferred to the post-weaving machine.

[0018] S2, Clamping: The electrofusion tube body that needs to be wired is clamped by the second electrofusion tube clamp and the first electrofusion tube clamp;

[0020] S4. After the groove is cut, the metal wire will be pressed into the cut thread groove by the metal wire pressing wheel to complete the wire laying.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In this invention, an automated wire feeding device and method for electrofusion fittings involves starting a fourth transmission cylinder to move a lifting platform downwards, increasing the length of the metal wire passing through the second inlet slot and the annular guide ring. Then, a second transmission motor is started, rotating the annular guide ring. This rotation slightly bends the metal wire until the annular guide ring presses the wire against the limiting plate and clamps it. Next, the fourth transmission cylinder is started, moving the lifting platform upwards, stretching the metal wire upwards until it enters the wire outlet and passes a certain distance beyond it, thus completing the wire feeding operation on one side of the outlet.

[0023] In this invention, an automated wire-laying device and method for electrofusion tube fittings involves cutting the metal wire, which then falls into the second fixed frame due to gravity. However, due to the two clamping plates, the friction between them prevents the end of the metal wire from falling further, causing the end of the metal wire to be higher than the clamping plates and vertically upward due to gravity. At this point, the fourth transmission cylinder is activated, moving the annular guide sleeve and the lifting moving platform downward, causing the end of the metal wire to pass through the second wire inlet groove and the annular guide sleeve. Subsequently, the second transmission motor is activated, rotating the annular guide sleeve to clamp the end of the metal wire between the limiting plates. This facilitates the subsequent wire-laying operation on the next electrofusion tube body, eliminating the need for repeated wire-laying operations and greatly simplifying the processing.

[0045] Two metal wire outlets 10 are provided on the outer wall of the electrofusion tube body 9, and the two metal wire outlets 10 are symmetrically arranged along the electrofusion tube body 9.

[0046] This embodiment also discloses a method for using an automated wire-laying device for electrofusion fittings:

[0047] Includes the following fabric weaving steps

[0048] S1. Preparation: Before the post-weaving process, the injection molding machine is used to form the tubes. The tubes are then removed by a robotic arm and allowed to cool naturally. Natural cooling results in good shrinkage stability. The tubes are then transferred to the post-weaving machine.

[0049] S2, Clamping: The electrofusion tube body 9, which needs to be wired, is clamped by the second electrofusion tube clamp 12 and the first electrofusion tube clamp 8;

[0050] S3, Grooving: Then start the third drive motor 101 to rotate the electrofusion tube body 9, and start the second drive cylinder 15 and the third drive cylinder 17 to adjust the position of the second fixed frame 21 so that it extends into the rotating electrofusion tube body 9 to groove.

[0051] S4. After the groove is cut, the metal wire 25 will be pressed into the cut thread groove by the metal wire pressing wheel 34 to complete the wire laying.

[0052] In this embodiment: Currently available electrofusion tube post-wire laying equipment requires manual pulling of one end of the copper wire from the metal wire outlet of the electrofusion tube body during the post-wire laying process, which is inconvenient for automated post-wire laying operation.

[0053] Therefore, before the post-filament fabrication process, the injection molding machine first forms the tube, and the tube is removed by the robotic arm and cooled naturally. Natural cooling results in good shrinkage stability. Then it is transferred to the post-filament fabrication machine. First, one end of the electrofusion tube body 9 that needs to be filament fabricated is placed into the inner wall of the second electrofusion tube clamp 12. Then, the first transmission cylinder 7 is started. The first transmission cylinder 7 moves the first electrofusion tube clamp 8 at the output end and clamps the electrofusion tube body 9 together with the second electrofusion tube clamp 12.

[0054] After clamping is completed, the third drive motor 101 is started. The third drive motor 101 drives the first drive pulley 2 at the output end to rotate. When the first drive pulley 2 rotates, it drives the drive belt 3 to rotate together. When the drive belt 3 rotates, it drives the second drive pulley 4 embedded in the inner wall to rotate together. As the second drive pulley 4 rotates, it drives the first horizontal shaft 5 on the inner wall to rotate together. The rotation of the first horizontal shaft 5 will drive the first fixed frame 6 and the first drive cylinder 7 to rotate together. The rotation of the first drive cylinder 7 will drive the first electrofusion tube clamp 8, the electrofusion tube body 9, and the second electrofusion tube clamp 12 to rotate synchronously together.

[0055] Then the metal wire 25 that needs to be filamented is inserted into the first inlet groove 1901. Then the first drive motor 22 is started. After the first drive motor 22 is started, it drives the third horizontal shaft 23 at the output end to rotate. When the third horizontal shaft 23 rotates, it feeds the metal wire 25 sandwiched between the third horizontal shaft 23 and the fourth horizontal shaft 24 into the first inlet groove 1901.

[0056] Then, the second transmission cylinder 15 is started. After the second transmission cylinder 15 is started, it carries the first slider 16 to slide along the sliding guide rail 14 towards the side closer to the electrofusion tube body 9 until the second fixing frame 21 is slid into the interior of the electrofusion tube body 9. When the second fixing frame 21 and the metal wire outlet 10 on one side of the electrofusion tube body 9 are on the same vertical line, the second transmission cylinder 15 is closed and the third transmission motor 101 is started to rotate the electrofusion tube body 9 to the position where the metal wire outlet 10 is directly opposite the inner ring of the annular guide collar 29.

[0057] Upon first use, the metal wire 25 needs to be manually threaded through the second inlet slot 30 and the annular guide collar 29. Then, the first drive motor 22 continues to feed the metal wire 25 into the first inlet slot 1901. As the metal wire 25 continues to be fed, it bends and is fed into the interior of the second fixed frame 21. At this point, the fourth drive cylinder 26 is activated, moving the lifting platform 27 into the interior of the second fixed frame 21, increasing the length of the metal wire 25 passing through the second inlet slot 30 and the annular guide collar 29. Then, the second drive motor 28 is activated... After the second drive motor 28 starts, it rotates the annular guide ring 29. The rotation of the annular guide ring 29 will slightly bend the metal wire 25 until the annular guide ring 29 rotates and presses the metal wire 25 against the limit plate 31 and clamps it. At this time, the fourth drive cylinder 26 is activated to move the lifting moving platform 27 as a whole, which will stretch the metal wire towards the metal wire outlet 10 until it enters the metal wire outlet 10 and passes through the metal wire outlet 10 for a distance. At this time, the wire exit operation of one side of the metal wire outlet 10 is completed, as shown in the attached figure. Figure 7 As shown;

[0058] Then, the third transmission cylinder 17 is activated, causing the second slider 19 at the output end to slide along the groove 18. At this time, the guide rod 20 connected to the second slider 19 and the second fixed frame 21 move synchronously until the electrofusion tube grooving knife 35 outside the second fixed frame 21 abuts against the inner wall of the rotating electrofusion tube body 9. As the electrofusion tube body 9 continues to rotate, the inner wall of the electrofusion tube body 9 will be cut with a groove by the electrofusion tube grooving knife 35. At the same time, the second transmission cylinder 15 is activated to cause the second fixed frame 21 to move. The second fixed frame 21 moves along the inner wall of the electrofusion tube body 9 with the electrofusion tube grooving knife 35. With the uniform linear movement of the electrofusion tube grooving knife 35 and the electrofusion tube... The uniform rotation of the tube body 9 creates uniform threaded grooves on the inner wall of the electrofusion tube body 9. After the electrofusion tube grooving knife 35 creates the grooves, the metal wire pressing wheel 34 presses the upper metal wire 25 into the newly created threaded grooves. For the middle part of the inner wall of the electrofusion tube body 9, which requires a larger pitch threaded groove, it is only necessary to slow down the rotation speed of the electrofusion tube body 9 and the movement speed of the second fixed frame 21. That is, control the movement speed of the output end of the second transmission cylinder 15 and the rotation speed of the output end of the third transmission motor 101. At the same time, the other side of the electrofusion tube body 9 is also grooved and pressed with metal wire 25 in the same way as described above. Figure 8 As shown.

[0059] Example 2

[0060] This embodiment aims to address the problem in Embodiment 1 where, when leading out the metal wire 25 from the second metal wire outlet 10, the metal wire 25 needs to be cut. However, the cut end of the metal wire 25 falls off, and when laying the wire on the next electrofusion tube body 9, the end of the metal wire 25 needs to be located, aligned, and inserted into the second wire inlet groove 30 and the annular guide collar 29. This operation is repetitive and inconvenient. This embodiment is an improvement based on Embodiment 1. For details, please refer to... Figures 1-10 Two fifth transmission cylinders 32 are installed on the inner wall of the second fixed frame 21. The output ends of the two fifth transmission cylinders 32 are fixedly connected to wire cutting blades 33, and the two wire cutting blades 33 are arranged in a horizontal direction.

[0061] The inner wall of the second fixed frame 21 is fixedly connected to two return springs 36, and one end of the two return springs 36 is fixedly connected to a clamping plate 37.

[0062] In this embodiment: In Embodiment 1, when the metal wire 25 is led out from the second metal wire outlet 10, the metal wire 25 needs to be cut. However, the cut end of the metal wire 25 will fall off. When laying the wire on the next electrofusion tube body 9, the end of the metal wire 25 needs to be found and aligned before being inserted into the second wire inlet groove 30 and the annular guide collar 29. The operation is repetitive and inconvenient.

[0063] To prevent the above situation from occurring, the fourth transmission cylinder 26 is activated, moving the lifting platform 27 into the interior of the second fixed frame 21. This increases the length of the metal wire 25 as it passes through the annular guide ring 29, allowing its end to pass through the metal wire outlet 10. The metal wire 25 is then pulled up as shown in the attached diagram. Figure 9 After reaching the state shown, the two fifth transmission cylinders 32 are activated. These cylinders, along with the wire cutting blades 33 at their output ends, move closer together to cut the metal wire 25. After the wire 25 is cut, the friction between the two clamping plates 37 restricts the end of the wire 25, causing it to protrude beyond the clamping plates 37. At this point, the fourth transmission cylinder 26 is activated, moving the annular guide ring 29 and the lifting platform 27 downwards, causing the end of the wire 25 to pass through the second inlet slot 3. 0 and the annular guide collar 29, but at this time the length of the metal wire 25 protruding from the annular guide collar 29 is insufficient to be clamped between the limiting plates 31 by the rotated annular guide collar 29. Therefore, the fourth transmission cylinder 26 should be started to make the annular guide collar 29 continue to move and press the limiting plate 31, causing the return spring 36 at one end of the limiting plate 31 to bend under force, and move the limiting plate 31 towards the position close to the first wire inlet groove 1901, so that the length of the metal wire 25 passing through the limiting plate 31 increases, making it easier for the annular guide collar 29 to bend and clamp it.

[0064] Then, the second drive motor 28 is started to rotate the annular guide ring 29, which restricts the end of the metal wire 25 between the limiting plates 31. This makes it easier to perform the subsequent wire laying operation on the next electrofusion tube body 9, eliminating the need to repeatedly thread the metal wire 25 and greatly facilitating the processing.

[0066] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
