Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] In this design, the core positioning and guiding mechanism is installed on the bottom bracket at the cable inlet of the cable extruder.

[0022] like Figures 1-6 As shown, a core positioning and guiding mechanism includes a support frame 1, two symmetrically distributed support plates 2 are fixedly connected to the right side of the support frame 1, an extruder body 3 is provided on the right side of the support frame 1, an adjustment mechanism 4 is provided on the support frame 1, and a limit mechanism 5 is provided on the support frame 1. The adjustment mechanism 4 includes a threaded rod 41 that is rotatably connected to the top of the front support plate 2. The two support plates 2 are provided with fixed grooves 42 on opposite sides, and movable blocks 43 are slidably connected inside the two fixed grooves 42. The limiting mechanism 5 includes a second motor 51 fixedly installed on the back of the support frame 1. The output shaft of the second motor 51 is fixedly connected to a first connecting plate 52, and a fixed rod 53 is slidably connected to one side of the support frame 1.

[0023] It should be noted that by setting up the cleaning pad 459, the wire core can be easily protected during the cleaning process, avoiding scratches on the wire core. The cleaning pad 459 is a cleaning sponge, which makes it easy to remove dust.

[0024] like Figures 1-6 As shown, the outer side of the threaded rod 41 is threadedly connected to the inner side of the front movable block 43, and a fixing plate 44 is fixedly connected to the opposite side of the two movable blocks 43. A cleaning component 45 is provided on the fixing plate 44.

[0025] It should be noted that rotating the threaded rod 41 causes the movable block 43 to slide up and down inside the fixed groove 42, thereby facilitating the adjustment of the height of the fixed plate 44 and making it easier for the cylinder 452 to correspond with the feed inlet of the extruder body 3.

[0026] like Figures 1-6As shown, the cleaning assembly 45 includes a housing 451 fixedly connected to the top of a fixed plate 44. A cylindrical body 452 is rotatably connected inside the housing 451. An arc-shaped plate 453 is slidably connected inside the cylindrical body 452. Positioning blocks 454 are fixedly connected to the top and bottom of the arc-shaped plate 453. A first gear 455 is fixedly connected to the outside of the cylindrical body 452. A first motor 456 is fixedly mounted on one side of the housing 451. A rotating shaft 457 is fixedly connected to the output shaft of the first motor 456. A second gear 458 is fixedly connected to the outside of the rotating shaft 457. A cleaning pad 459 is fixedly connected inside the arc-shaped plate 453. Bolts 4510 are threaded to the top and bottom of 452. One end of the bolts 4510 extends into the interior of the positioning block 454. The bottom of the fixing plate 44 is fixedly connected to the chamber 4511. An air pump 4512 is fixedly installed on the right side of the chamber 4511. A filter plate 4513 is fixedly connected inside the chamber 4511. A collection box 4514 is slidably connected inside the chamber 4511. A fixing pipe 4515 is fixedly connected to the left side of the chamber 4511. An annular pipe 4516 is fixedly connected to one end of the fixing pipe 4515. Multiple suction heads 4517 distributed circumferentially are fixedly connected to the annular pipe 4516.

[0027] It should be noted that when the air pump 4512 is started, it creates negative pressure inside the chamber 4511, which in turn creates negative pressure on the multiple suction heads 4517, facilitating the absorption of impurities adhering to the wire core. The impurities are then discharged into the chamber 4511 through the annular pipe 4516 and the fixed pipe 4515, where they are filtered by the filter plate 4513, causing them to fall into the collection box 4514 for collection. The second motor 51 is started, and its output shaft drives the first connecting plate 52 to rotate, which in turn drives the unwinding roller 55 to rotate, facilitating the unwinding of the wire core. The first motor 456 is started, and its output shaft drives the rotating shaft 457 to rotate, which in turn drives the second gear 458 to rotate, which in turn drives the first gear 455 to rotate, which in turn drives the cylinder 452 to rotate, which in turn drives the arc plate 453 and the cleaning pad 459 to rotate, cleaning the wire core.

[0028] like Figures 1-6 As shown, two symmetrically distributed positioning grooves are provided on the cylinder 452, and the size of the positioning block 454 is adapted to the size of the positioning groove.

[0029] It should be noted that unscrewing bolt 4510 makes it easy to pull the arc plate 453 out of the inside of the cylinder 452, and at the same time, it allows the positioning block 454 to be pulled out of the inside of the positioning groove, thus facilitating the replacement of the arc plate 453 and the cleaning pad 459.

[0030] like Figures 1-6As shown, the size of the second gear 458 is larger than that of the first gear 455, and the outer side of the first gear 455 meshes with the outer side of the second gear 458.

[0031] It should be noted that this improves transmission efficiency, which in turn improves the cleaning effect.

[0032] like Figures 1-6 As shown, a handle 511 is fixedly connected to one end of the fixed rod 53, and a second connecting plate 54 is rotatably connected to the other end of the fixed rod 53. A unwinding roller 55 is slidably connected inside the first connecting plate 52 and the second connecting plate 54. A box body 56 is fixedly connected to one side of the support frame 1. A limit rod 57 is slidably connected inside the box body 56. A limit plate 58 is fixedly connected to the outside of the limit rod 57. A spring 59 is sleeved on the outside of the limit rod 57. Two symmetrically distributed connecting blocks 510 are fixedly connected to the top and bottom of the unwinding roller 55.

[0033] It should be noted that when the limiting rod 57 is pulled down, the limiting rod 57 compresses the spring 59 through the limiting plate 58, thereby pulling the limiting rod 57 out of the limiting groove. Then, the fixing rod 53 is pulled by the handle 511, which makes it easy to remove the second connecting plate 54 from the unwinding roller 55, thereby facilitating the replacement of the unwinding roller 55 and improving the working efficiency of the wire core extrusion operation.

[0034] like Figures 1-6 As shown, the first connecting plate 52 and the second connecting plate 54 are provided with two connected grooves distributed in a pair, and the size of the connecting block 510 is adapted to the size of the connected groove.

[0035] It should be noted that this facilitates the rotation of the unwinding roller 55.

[0036] like Figures 1-6 As shown, a limiting groove is provided at the bottom of the fixing rod 53, and the size of the limiting rod 57 is adapted to the size of the limiting groove.

[0037] It should be noted that this facilitates the limiting and fixing of the fixing rod 53, and in turn facilitates the limiting and fixing of the unwinding roller 55.

[0038] The working principle of this utility model is as follows: When in use, by setting the adjustment mechanism 4, rotating the threaded rod 41 causes the movable block 43 to slide up and down inside the fixed groove 42, thereby facilitating the adjustment of the height of the fixed plate 44. This allows the cylinder 452 to correspond to the feed inlet of the extruder body 3. One end of the wire core on the unwinding roller 55 passes through the inside of the annular tube 4516, and then through the inside of the arc plate 453 before being inserted into the inside of the extruder body 3. The part between the unwinding roller 55 and the extruder body 3 has a certain tension and remains taut under the action of tension. During the conveying process of the wire core inside the cylinder 4512, the vacuum pump 4512 is activated, creating negative pressure inside the chamber 4511. This negative pressure is then generated by the multiple suction heads 4517, facilitating the absorption of impurities adhering to the wire core. The impurities are then discharged into the chamber 4511 through the annular pipe 4516 and the fixed pipe 4515. A filter plate 4513 filters the impurities, causing them to fall into the collection box 4514 for collection. The second motor 51 is then activated, and its output shaft drives the first connecting plate 52 to rotate. Plate 52 drives the unwinding roller 55 to rotate, facilitating the unwinding of the wire core. The first motor 456 is started, and its output shaft drives the rotating shaft 457 to rotate. The rotating shaft 457 drives the second gear 458 to rotate, which in turn drives the first gear 455 to rotate. The first gear 455 drives the cylinder 452 to rotate, which in turn drives the arc-shaped plate 453 and the cleaning pad 459 to rotate, cleaning the wire core and facilitating its entry into the extruder body 3 for extrusion. A limiting mechanism 5 is set, and a forklift supports the unwinding roller 55, allowing it to... Pull down the limiting rod 57, and the limiting rod 57 will press the spring 59 through the limiting plate 58, thereby pulling the limiting rod 57 out of the limiting groove. Then, pull the fixing rod 53 through the handle 511, so as to easily remove the second connecting plate 54 from the unwinding roller 55, thereby facilitating the replacement of the unwinding roller 55 and improving the working efficiency of the wire core extrusion operation. Unscrew the bolt 4510 to easily pull the arc plate 453 out of the cylinder 452, and at the same time, pull the positioning block 454 out of the positioning groove, thereby facilitating the replacement of the arc plate 453 and the cleaning pad 459.

[0039] In addition, this case also discloses a cable extruder for use in conjunction with a core positioning and guiding mechanism.
