[0026] Reference Figures 1 to 6 The electrically fused pipe production equipment according to a preferred embodiment of the present application will be described in detail below. The electrically fused pipe production equipment includes a winding device 100 and a wire loading device 200, wherein the wire loading device 200 includes a wire loading column 90. The wire loading column 90 forms a winding portion 91, and the winding portion 91 forms a starting end portion 911 and an end end portion 912 opposite to the starting end portion 911. The winding device 100 is used to unwind a wire coil into a wire and wind the wire around the outer periphery of the winding portion 91 formed by the wire loading column 90.

[0027] Specifically, the winding device 100 includes a device main body 10, a winding and unwinding mechanism 20, and a wire arranging mechanism 30.

[0028] The wire winding and unwinding mechanism 20 comprises a wire unwinding member 21 and a wire winding member 22. The wire unwinding member 21 comprises a winding shaft 211 mounted on the device body 10, and a wire coil is mounted on the winding shaft 211. The wire winding member 22 is mounted on the device body 10, and the wire winding column 90 is detachably mounted on the wire winding member 22, and the wire winding member 22 is used to drive the wire winding column 90 to rotate around its own axis. The electric heating wire unwound from the wire coil carried by the winding shaft 211 is wound around the winding part 91 of the wire winding column 90 driven to rotate by the wire winding member 22. The wire arranging mechanism 30 is mounted on the device body 10 to adjust the arrangement of the electric heating wire when the wire winding column 90 is driven to rotate by the wire winding member 22 to wind the electric heating wire, so that the electric heating wire is spirally distributed from the starting end part 911 to the ending end part 912.

[0029] Preferably, the outer circumferential wall of the wire winding column 90 further forms two electric connection parts 92, and the two electric connection parts 92 are respectively adjacent to the starting end part 911 and the ending end part 912. The wire carrying device 200 further comprises a pair of wire fixing members 80, and the first and last ends of the electric heating wire wound around the wire winding column 90 are respectively fixed by one of the wire fixing members 80. The electric connection part 92 forms a slot 9201, and the wire fixing member 80 is inserted into the slot 9201 formed by the electric connection part 92.

[0030] That is, the first end of the electric heating wire unwound from the wire coil is fixed by one of the wire fixing members 80 and inserted into the slot 9201 formed by the electric connection part 92 close to the starting end part 911; then, the wire winding member 22 drives the wire winding column 90 to rotate around its own axis, and at the same time, the wire arranging mechanism 30 adjusts the winding of the electric heating wire from the starting end part 911 to the ending end part 912; after the winding of the wire winding column 90 is completed, the electric heating wire is cut, and the last end of the electric heating wire wound around the wire winding column 90 is fixed by the other wire fixing member 80 and inserted into the slot 9201 formed by the electric connection part 92 close to the ending end part 912, so as to obtain the semi-finished product of the electric melting pipe.

[0031] It is worth mentioning that the wire winding column 90 is detachably mounted on the device body 10, so that when the electric heating wire is wound around the winding part 91 formed by the wire winding column 90, the wire winding column 90 heats the electric heating wire through heat conduction, so that the insulating plastic on the outer periphery of the electric heating wire is melted and attached to the outer circumferential wall of the winding part 91, so as to avoid the loosening of the electric heating wire wound around the outer circumferential wall of the winding part 91 of the wire winding column 90 when the electric heating wire is cut.

[0032] In an embodiment, the take-up member 22 comprises a driving member 221 and a belt rotating shaft 222, the driving member 221 is mounted on the device body 10, and the belt rotating shaft 222 is drivingly connected to the driving member 221. The take-up post 90 is detachably connected to the belt rotating shaft 222 in a coaxial manner, and the driving member 221 drives the take-up post 90 to rotate through the belt rotating shaft 222, so as to wind the electric heating wire.

[0033] In an example, the driving member 221 is implemented to comprise a motor.

[0034] Preferably, the belt rotating shaft 222 forms a clamping structure, and the take-up post 90 forms a fitting structure matched with the clamping structure, the take-up post 90 is inserted into the belt rotating shaft 222 in a manner that the fitting structure is clamped with the clamping structure, so that the belt rotating shaft 222 drives the take-up post 90 to rotate through the cooperation of the clamping structure and the fitting structure.

[0035] As an example, the clamping structure is implemented as a protrusion, and the fitting structure is implemented as a groove, wherein the groove is formed on the side wall of the hole in which the belt rotating shaft 222 is inserted into the take-up post 90.

[0036] Further, the take-up member 22 further comprises a driving member 212, and the take-up shaft 211 is drivingly connected to the driving member 212, and the driving member 212 drives the take-up shaft 211 to rotate, so as to drive the take-up shaft 211 to rotate to actively unwind the electric heating wire.

[0037] In an example, the driving member 212 is implemented to comprise a motor.

[0038] Specifically, the take-up mechanism 30 comprises an adjusting assembly 31, and the adjusting assembly 31 is mounted on the device body 10.

[0039] In an embodiment, the take-up post 90 is drivingly connected to the adjusting assembly 31, and the adjusting assembly 31 is used to drive the take-up post 90 to move along the axial direction of the take-up post 90. Specifically, when the take-up post 90 is driven to rotate by the take-up member 22 to wind the electric heating wire, the adjusting assembly 31 drives the take-up post 90 to move from the direction that the take-up post 90 extends from the end portion 912 to the starting end portion 911.

[0040] Preferably, the take-up mechanism 30 further comprises a lead member 32, and the lead member 32 is mounted on the device body 10, and the lead member 32 is located between the take-up member 21 and the take-up post 90. The electric heating wire unwound from the wire coil is guided to the winding portion 91 formed by the take-up post 90 through the lead member 32.

[0041] In another embodiment, the device body 10 comprises a device body 11 and a moving platform 12, wherein the adjusting assembly 31 is mounted on the device body 11, the lead member 32 is mounted on the moving platform 12, and the moving platform 12 is drivingly connected to the adjusting assembly 31, and the adjusting assembly 31 drives the moving platform 12 to move along the axial direction parallel to the winding column 90, so that the moving platform 12 drives the lead member 32 to move along the axial direction parallel to the winding column 90. Specifically, when the winding column 90 is driven to rotate by the winding member 22 to wind the electric heating wire, the adjusting assembly 31 drives the lead member 32 to move along the direction parallel to the extension from the starting end 911 to the ending end 912 through the moving platform 12.

[0042] As an example, the adjusting assembly 31 is implemented as a cylinder or a screw motor mechanism.

[0043] It is worth mentioning that the lead member 32 forms a through hole 3201, and the electric heating wire unwound from the wire coil is wound around the winding part 91 of the winding column 90 after passing through the through hole 3201 formed by the lead member 32.

[0044] Further, the winding device 100 further comprises a tension adjusting mechanism 40. The tension adjusting mechanism 40 comprises a first tension adjusting member 41.

[0045] Specifically, the first tension adjusting member 41 comprises a first counterbalance 411, which is elastically connected with the lead member 32 and the moving platform 12. The first counterbalance 411 is arranged to be elastically deformed and has a tendency to return to its original shape after being elastically deformed. The lead member 32 is slidingly mounted on the moving platform 12. The first counterbalance 411 exerts a force on the lead member 32, which is opposite to the resultant force of the electric heating wire passing through the through hole 3201 formed by the lead member 32. When the resultant force of the electric heating wire passing through the through hole 3201 formed by the lead member 32 and the force of the first counterbalance 411 on the lead member 32 are unbalanced, the lead member 32 slides relative to the moving platform 12 under the elastic force of the first counterbalance 411 or the tension of the electric heating wire passing through the through hole 3201 formed by the lead member 32, so as to balance the tension of the electric heating wire.

[0046] In an embodiment, when the resultant force exerted on the lead member 32 by the electric heating wires passing through the perforations 3201 formed in the lead member 32 is greater than the force exerted on the lead member 32 by the first counterbalance member 411, the lead member 32 moves under tension in a direction to press the first counterbalance member 411, to relieve the tension of the unwound electric heating wires. When the tension of the electric heating wires passing through the perforations 3201 formed in the lead member 32 is insufficient, the lead member 32 moves under the elastic force of the first counterbalance member 411 in a direction to return to the original position, to tension the electric heating wires, so that the electric heating wires remain taut.

[0047] In an example, the first counterbalance member 411 is implemented as a spring.

[0048] Preferably, the first tension adjusting member 41 comprises a guide member 412, the first counterbalance member 411 is sleeved on the guide member 412, and the guide member 412 is connected to the lead member 32 in an extendable or movable manner, the guide member 412 is used to define the extension direction of the first counterbalance member 411, to prevent the first counterbalance member 411 from being displaced when compressed. As an example, the guide member 412 is implemented as an optical axis.

[0049] Preferably, the take-up and pay-off mechanism 20 further comprises a transmission member 23, the transmission member 23 comprises a first transmission wheel 231 and a second transmission wheel 232, wherein the first transmission wheel 231 and the second transmission wheel 232 are both mounted on the moving platform 12. The first transmission wheel 231 is located between the guide member 412 and the loading shaft 211, and the second transmission wheel 232 is located between the guide member 412 and the take-up member 22. The electric heating wires unwound from the wire coil are wound on the winding portion 91 formed in the wire column 90 after passing through the first transmission wheel 231, the perforations 3201 formed in the lead member 32, and the second transmission wheel 232 in sequence, so that the first transmission wheel 231, the second transmission wheel 232, and the lead member 32 form a triangular structure, and the lead member 32 is moved relative to the moving platform 12 to adjust the angle between the first transmission wheel 231, the second transmission wheel 232, and the lead member 32, to balance the tension of the unwound electric heating wires.

[0050] Further, the tension adjusting mechanism 40 further comprises a second tension adjusting member 42, which comprises a second counterweight 421, a connecting member 422 and a tension roller 423. The tension roller 423 is mounted on the connecting member 422, and the electric heating wire unwound from the wire roll passes through the tension roller 423 and is wound on the winding portion 91 formed by the wire loading column 90. The connecting member 422 is rotatably mounted on the device main body 10 along a vertical plane. The second counterweight 421 is connected to the connecting member 422, and the second counterweight 421 is used to drive the connecting member 422 to rotate along the vertical plane, so that the connecting member 422 drives the tension roller 423 to move, thereby adjusting the tension of the electric heating wire between the loading shaft 211 and the wire loading column 90, so as to keep the electric heating wire unwound between the loading shaft 211 and the wire loading column 90 taut. The second counterweight 421 drives the connecting member 422 to exert an upward force on the tension roller 423, which is opposite to the resultant force exerted by the electric heating wire passing through the tension roller 423 on the tension roller 423.

[0051] Specifically, when the tension of the electric heating wire unwound between the loading shaft 211 and the wire loading column 90 is insufficient, the resultant force exerted by the electric heating wire passing through the tension roller 423 on the tension roller 423 is smaller than the force exerted by the second counterweight 421 on the tension roller 423 through the connecting member 422, and at this time, the second counterweight 421 drives the connecting member 422 to move the tension roller 423 in a direction opposite to the direction of the resultant force exerted by the electric heating wire passing through the tension roller 423 on the tension roller 423, so as to tension the electric heating wire by the tension roller 423. When the tension of the electric heating wire unwound between the loading shaft 211 and the wire loading column 90 is too large, the resultant force exerted by the electric heating wire passing through the tension roller 423 on the tension roller 423 is larger than the force exerted by the second counterweight 421 on the tension roller 423 through the connecting member 422, and at this time, the second counterweight 421 drives the connecting member 422 to move the tension roller 423 in a direction opposite to the direction of the resultant force exerted by the electric heating wire passing through the tension roller 423 on the tension roller 423, so as to balance the tension.

[0052] In an embodiment, the second counterweight 421 is implemented as a weight tied to an end of the connecting member 422 away from the tension roller 423. The second counterweight 421 exerts a downward force on the end of the connecting member 422 away from the tension roller 423 by its own gravity, so as to exert an upward force on the tension roller 423 by the connecting member 422. The resultant force exerted by the electric heating wire passing through the tension roller 423 on the tension roller 423 is downward.

[0053] As deformable, the second counterbalance 421 is implemented as a torsion spring, which is kept in a compressed state and sleeved on the shaft connecting the connecting member 422 and the device body 10, and the second counterbalance 421 rotates the connecting member 422 mounted with the tension roller 423 at one end thereof in a top-down direction by the shaft.

[0054] Preferably, the conducting member 23 comprises a plurality of third transmission wheels 233, which are bypassed by the electric heating wire unwound from the device body 11 via the charging shaft 211, so as to be transmitted by the third transmission wheels 233.

[0055] In the process of unwinding the wire coil, the tension of the electric heating wire of each unwound part is different, so that at least one first tension adjusting member 41 or / and at least one second tension adjusting member 42 can be arranged along the path of the electric heating wire to adjust the tension of the electric heating wire. In one embodiment, a second tension adjusting member 42 and a first tension adjusting member 41 are arranged in sequence along the path of the electric heating wire. Specifically, the electric heating wire wound on the wire coil is wound around the third transmission wheel 233, the tension roller 423, the first transmission wheel 231, the through hole 3201 formed by the lead member 32, and the second transmission wheel 232, and then wound on the winding part 91 formed by the wire column 90.

[0056] It is worth mentioning that the peripheral wall of the first transmission wheel 231, the second transmission wheel 232 and the third transmission wheel 233 is formed with a wire groove 2301. The electric heating wire unwound is wound in the wire groove 2301 formed by the first transmission wheel 231, the second transmission wheel 232 and the third transmission wheel 233 in sequence, so as to prevent the electric heating wire from being separated from each wheel.

[0057] It should be understood by those skilled in the art that the above description and the embodiments of the present application shown in the drawings are only examples and do not limit the present application. The advantages of the present application have been fully and effectively achieved. The function and structural principle of the present application has been shown and explained in the embodiments, and the embodiments of the present application can be any modification or modification without departing from the principle.
