Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a cable production line capable of automatically adjusting the thickness of a cable sheath. Background Art

[0002] The cable sheath is the outermost structure of the cable or wire, usually made of PVC, PE, PUR and other materials. It protects the internal structure of the cable from external damage, such as mechanical damage, chemical corrosion, moisture erosion, etc. The cable sheath also has the functions of fixing the cable shape, shielding electromagnetic interference, and flame retardant, ensuring that the cable can still operate stably in harsh environments; the sheath is generally extruded and laid on the surface of the cable through extrusion equipment to complete the protection of the cable.

[0003] For example, a Chinese patent application with publication number CN102982919A discloses a cable production line that can automatically adjust the thickness of a cable sheath. The production line includes an extrusion device for laying the sheath on the conductor; an electronic thickness measuring unit for instantly measuring the outer diameter r of the sheath; a winding unit for pulling the cable; a main control unit connected to the electronic thickness measuring unit for controlling the pulling speed of the winding unit; when the outer diameter r is higher than / lower than a predetermined threshold value R, the main control unit will control the pulling speed of the winding unit to increase / decrease.

[0004] However, there are still some problems with the existing production equipment with adjustable cable sheaths. The existing equipment measures the thickness of the sheath, compares the measured value with the preset value, and adjusts the traction or reeling speed of the traction device or the reeling device according to the comparison result, so as to increase or decrease the thickness of the sheath. Since the sheaths are extruded by an extruder, in order to quickly restore them to normal temperature, they need to be placed in a cooling pool filled with water, or their surface needs to be sprayed with a water pipe to cool them down. However, since there is no sheath at the free end of the cable, and the cable will move toward the coolant under its own weight, water will enter both ends of the cable, which can easily cause damage to the cable.

[0005] Therefore, how to prevent both ends of the cable from coming into contact with the coolant during the process of laying the sheath is a problem that needs to be solved at present. Summary of the invention

The adjustment platform 3 is a cross slide, that is, two mutually perpendicular moving screw linear slides; The second slider 442 is fixed on the rotating disk 441 by screws; The drying chamber 54 is a tubular structure, and a plurality of heating resistance wires are provided on its inner wall. The heating resistance wires are connected to a power source and are used to dry water droplets attached to the sheath. The cable passes through two groups of first limiting wheels 434 in the first upward component 43 and then passes through two second limiting wheels 443 in the second upward component 44. The spray head 4212 is connected to the delivery pump through a delivery pipe, so that water can be sprayed out from the spray head 4212.

[0033] Description of the working principle: When it is necessary to lay the sheath on the cable, the raw materials used to produce the sheath can be poured into the extruder 2, and then the cable is passed through the extruder 2 and penetrated from the extrusion area of ​​the sheath, and then the sheath is laid on the cable, and then the traction device is connected to the cable, and then the cable is passed through the cooling pool 6 by the movement of the traction device. Under the influence of its own weight, part of the cable will be immersed in the coolant to complete the cooling of the sheath; when the first upturned component 43 and the second upturned component 44 are required to work, the adjusting motor 4511 starts to work, and the moving adjusting motor 4511 can drive the driving gear 4512 to rotate, and then the moving driving gear 4512 can drive the driven gear 4513 meshing therewith to rotate, and then the rotating driven gear 4513 can drive the second connecting shaft 4 514 rotates, thereby driving the rotating seat 4515 to rotate, the moving rotating seat 4515 can drive the first connecting rod 4516 to move, and then the first connecting rod 4516 drives the second connecting rod 4517 to move, and adjusts the angle between the first connecting rod 4516 and the second connecting rod 4517, thereby driving the first upward tilting component 43 to deviate, so that the first upward tilting component 43 moves, and the adjustment part 452 can drive the third connecting rod 453 to move, and the moving third connecting rod 453 can drive the transmission part 454 to move, and finally the moving transmission part 454 drives the second upward tilting component 44 to rotate, due to the cooperation between the adjustment part 452 and the transmission part 454, the rotation directions of the first upward tilting component 43 and the second upward tilting component 44 are opposite, so that the free end of the cable can be in an upward state; In the initial preparation stage, the displacement motor 4522 starts to work, and the moving displacement motor 4522 can drive the moving screw 4523 to rotate, and then the moving screw 4523 can drive the moving block 4524 to move, so that the moving moving block 4524 can move on the adjustment seat 4521, and the position of the moving block 4524 on the adjustment seat 4521 is changed, so as to adjust the distance from the moving block 4524 to the center of the circle of the driven gear 4513, so as to adjust the moving speed of the sliding seat 4546 driven by the third connecting rod 453, so as to change the offset angle of the second upward tilting component 44, so as to avoid that the offset angle of the cable driven by it is too large, which causes the cable to bend too much, making it difficult for the traction equipment to perform the traction work and damaging the cable; When the second tilting component 44 needs to start working, the moving driven gear 4513 can drive the adjusting part 452 to move, thereby driving the third connecting rod 453 to move, and the moving third connecting rod 453 can drive the sliding seat 4546 to slide in the fixing seat 4541, and then the moving sliding seat 4546 can drive the sliding bar 4542 to move, and then the moving sliding bar 4542 can drive the sub-gear 4543 to rotate, so that the moving sub-gear 4543 can drive the rotating shaft 4545 to rotate, thereby driving the second tilting component 44 to rotate, adjust the offset angle of the second tilting component 44, and complete the tilting work of the free end of the cable; When cooling is required, the driving cylinder 423 starts to work, and the moving driving cylinder 423 can drive the movable plate 424 to move. At this time, with the cooperation of the first slider 425, the movable plate 424 can move in the length direction of the slide rail 426, so that the guide wheel 427 can move in the guide groove 422, and then the connecting plate 429 is offset, so that the spraying area of ​​the spray head 4212 is adjusted through the set transmission shaft 4210 and the movable rod 4211, so that the area between the upturned part and the immersed part of the cable can be cooled, and then the cable can be cooled through the set traction device or winding unit 5 so that the cable can pass through the spraying area to complete the cooling of the cable; The cable is positioned on the reeling portion 58 after passing through the first guide wheel 52, the limit portion 53, the detection area of ​​the ultrasonic thickness gauge 510, the drying chamber 54, the second guide wheel 55 and the third guide wheel 59 in sequence. The cable is reeled in by the movement of the reeling portion 58. The rotation of the rotating motor 56 drives the adjusting screw rod 57 to move, and the position of the third guide wheel 59 in the length direction of the adjusting screw rod 57 is adjusted, thereby changing the reeling area of ​​the cable on the reeling portion 58 to complete the reeling of the cable. The ultrasonic thickness gauge 510 and the drying chamber 54 can detect the thickness of the sheath on the cable and dry the outer wall of the sheath. By detecting the thickness of the sheath, the traction and reeling speed of the traction device or the reeling device is changed to adjust the thickness of the sheath laid on the cable. In order to prevent the cable from colliding with the ultrasonic thickness gauge 510 or the inner wall of the drying chamber 54 during transportation, the position of the cable needs to be limited. At this time, the limit motor 531 starts to work, and the moving limit motor 531 can drive the first gear 532 to rotate, and then the moving first gear 532 can drive the ring gear 533 to rotate. The moving ring gear 533 drives the limit block 536 to move through the set driving rod 535, so that the limit block 536 and the fixed ring 537 rotate relative to each other, thereby adjusting the distance between the fixed ring 537 and the cable to limit the cable position.
