Description

Technical Field

[0001] The present invention relates to the field of cable processing, and in particular to a wire core guiding unit, a wire core coating device and cable manufacturing equipment. Background Art

[0002] The cable includes a core and a coating wrapped around the outside of the core. The main manufacturing process of the cable is: a feeding unit is used to heat the coating material from solid particles to a molten state and the molten coating material is transported to the mold core position of the coating unit, so that the coating material and the core merge and form a coating layer on the outside of the core, and the final cable is formed after cooling and molding. A guide component is usually provided at the upstream position of the coating unit, and the core passes through the guide component and then enters the above-mentioned mold core.

[0003] When the above-mentioned guiding components are used, the relative positions of wire cores of different specifications and sizes are different when passing through the mold core. That is to say, wire cores of different specifications and sizes cannot all be aligned with the center hole position of the mold core, thus causing the core wire to be eccentric relative to the mold core.

[0004] Even if the installation position of the guide component is adjusted by manual disassembly and assembly, when another type of cable is manufactured, the corresponding wire core and the corresponding mold core need to be replaced, and the installation position of the guide component needs to be manually disassembled and adjusted again. This method has low installation accuracy and complicated operation process; further, the weight of the wire core material will cause the wire core to sink. Different materials have different weights and sinking degrees, so when the wire core material changes, it is very difficult to adjust the alignment; it will still cause the cable to be eccentric, and then the cable coating will be uneven. Not only that, because the temperature of the wire core is low and the temperature of the mold core is high, after eccentricity, the wire core will be against the mold core, resulting in a decrease in the temperature of the part where the mold core and the wire core are in contact, making the temperature of the coating material uneven and the cooling degree uneven, causing uneven stress inside the cable package, and even causing small cracks, reducing the service life of the cable.

[0046] The moving mechanism 22 includes a first moving assembly 221, a second moving assembly 222 and a third moving assembly 223.

[0047] Specifically, refer to Figure 5 The first moving component 221 includes a first slide rail 2211 and a first slider, the first slide rail 2211 extends along the forward direction; the first slider is used to install the guide wheel bracket, and the first slider is embedded in the first slide rail 2211; the first slide rail 2211 contains a first screw rod and a first hand wheel 2213 combined with the first screw rod, the first slider contains a first screw rod nut screwed with the first screw rod, and the first screw rod can be rotated by rotating the first hand wheel 2213, and the first screw rod nut can be driven to move, thereby driving the first slider to move in the forward direction of the first slide rail 2211, and finally the guide wheel bracket 212 moves in the forward direction.

[0050] Reference Figure 4 , Figure 5 The wire core guide unit 20 further includes a base mechanism 23 for carrying the moving mechanism 22, and the base mechanism 23 includes a bottom plate portion 231 and a slide portion 232. The slide portion 232 is disposed on the bottom plate portion 231, and the slide portion 232 has a slide rail 2321 disposed on the bottom plate portion 231 and a slide block 2322 matched with the slide rail 2321 and fixed to the third slide rail 2231.

[0051] In order to make it easier and more accurate for the wire core a1 to be aligned with the center hole of the mold core, the first hand wheel 2213, the second hand wheel 2223 and the third hand wheel 2233 are respectively provided with a first dial, a second dial and a third dial.

[0052] The first scale plate is provided with a first reference mark and various first scale marks corresponding to different specifications of the wire core. When the guide wheel needs to carry a wire core of a predetermined specification and the first hand wheel 2213 is rotated so that the first scale mark corresponding to the predetermined specification is aligned with the first reference mark, the guide wheel is in a first pre-alignment position corresponding to the alignment position in the forward direction, indicating that the guide wheel 211 is currently in the alignment position in the forward direction.

[0053] The second scale plate is provided with a second reference mark and second scale marks corresponding to different specifications of the wire core. When the guide wheel needs to carry a wire core of a predetermined specification and the second hand wheel 2223 is rotated so that the second scale marks corresponding to the predetermined specification are aligned with the second reference mark, the guide wheel is in a second pre-alignment position corresponding to the alignment position in the vertical direction, indicating that the wire core a1 currently carried on the guide wheel 211 is aligned with the center hole of the mold core in the vertical direction;

[0055] The first pre-alignment position, the second pre-alignment position, and the third pre-alignment position are set based on the alignment position. Specifically, the specification of the core includes the diameter of the core and the unit weight based on the core material, and the greater the weight per unit length of the core a1, the easier it is for the core a1 to sink. The alignment position and the alignment spacing of the center entrance of the covering mold core are set based on the diameter and unit weight of the core, that is, the alignment positions of cores of different diameters are different, and even if the diameter of the core is the same, the alignment positions are different when the unit weight is different; the alignment positions of cores of various specifications and the corresponding first scale lines, second scale lines, and third scale lines can be determined by prior testing.

[0056] Figure 7 It is a partial structural schematic diagram of the guide wheel in the first embodiment.

[0057] Reference Figure 7 The guide wheel 211 has a guide groove 2111 on its periphery, and the guide groove has oblique side surfaces extending upward on both sides in a V-shaped manner. The position of the second scale line corresponding to the wire core is set based on the angle α between the two oblique side surfaces and the diameter D. For example, the height of the wire core a1 from the lowest point of the guide groove is H, then H=D / (2*sinα / 2). When the diameter D is different, the moving height of the guide wheel 211 is also different, and the specific value can be obtained by calculation.

[0058] The working principle of the cable manufacturing equipment in the first embodiment is as follows:

[0059] Before the cable manufacturing device 1000 works, the wire core needs to be inserted into the center hole of the core mold in the core coating unit 10, and then the wire core needs to be passed through the cooling device 200 and wound on the traction device, and then the guide wheel mechanism 21 is moved to align the guide wheel 211 with the center hole of the core mold of the core coating unit 10, and then the wire core a1 is passed around the auxiliary wheel 213 in the guide wheel mechanism 21, and abuts against the upper side of the guide wheel 211 to align the wire core a1 with the center hole of the core mold. The feeding unit 30 starts to work, and the coating material is delivered to the position of the core coating unit 10, and the traction device pulls the wire core a1 forward, and pulls the cable with the coating layer to continue to move forward.

[0060] When the wire core a1 needs to be replaced, the traction device and the feeding unit 30 stop running, and the guide wheel mechanism 21 is moved to a side away from the wire core coating unit 10 to prevent the wire core a1 from passing into the wire core coating unit 10 .

[0061] The process of moving the guide wheel mechanism 21 is as follows: the operator rotates the first hand wheel 2213 to move the first slider in the forward direction of the first slide rail 2211, and finally moves and rotates the guide wheel bracket 212 in the forward direction; rotates the second hand wheel 2223 to move the second slider 2222 in the up and down directions of the second slide rail 2221, and finally moves the guide wheel bracket 212 in the up and down directions; rotates the third hand wheel 2233 to move the third slider 2232 in the left and right directions of the third slide rail 2231, and finally moves the guide wheel bracket 212 in the left and right directions.

[0062] During the process of aligning the guide wheel 211 with the center hole of the mold core, the corresponding first scale line, second scale line and third scale line can be found according to the specifications of the current wire core, and the first hand wheel 2213 can be turned to align the first scale line corresponding to the current wire core with the first reference line; the second hand wheel 2223 can be turned to align the second scale line corresponding to the current wire core with the second reference line; and the third hand wheel 2233 can be turned to align the third scale line corresponding to the current wire core with the third reference line.

[0063] Functions and Effects of Embodiment 1

[0064] The first moving component 221 in the wire core guiding unit 20 can drive the guide wheel 211 to move in the forward direction, and can ensure that the wire core coating device 100 moves the guide wheel mechanism 21 to a position away from the wire core coating unit 10 before working, so as to facilitate the wire core a1 to be inserted into the wire core coating unit 10; and, after the wire core a1 is inserted into the wire core coating unit 10, the guide wheel 211 can be conveniently moved close to the wire core coating unit 10 to reduce the degree of sinking of the wire core a1 due to gravity; in addition, the second moving component 222 can conveniently drive and adjust the movement of the guide wheel 211 in the up and down directions, and then adjust the wire core a1 carried on the guide wheel 211 to be aligned with the center hole of the mold core in the wire core coating unit 10 in the up and down directions.

[0065] In addition, the third moving component 223 can drive the guide wheel 211 to move in the left and right directions, so that the core wrapping device 100 can move the guide wheel mechanism 21 to a position away from the core wrapping unit 10 before working, avoiding the process of the core a1 passing through the core wrapping unit 10, and facilitating the core a1 to pass through the core wrapping unit 10; and after the core a1 passes through the core wrapping unit 10, the guide wheel 211 can also be adjusted to move in the left and right directions and then align with the center hole of the mold core in the core wrapping unit 10 in the left and right directions.

[0066] The first slide rail 2211 , the first slider 2212 , the second slide rail 2221 , the second slider 2222 , the third slide rail 2231 and the third slider 2232 cooperate with each other to enable the guide wheel 211 to move more smoothly.

[0067] In Example 1, since there are a first screw rod, a first screw rod nut, a first handwheel 2213, a second screw rod, a second screw rod nut, a second handwheel 2223, a third screw rod, a third screw rod nut and a third handwheel 2233, it is only necessary to rotate the above three handwheels to achieve the moving guide wheel, so that the adjustment of the guide wheel is easier to achieve, and there is no need for manual disassembly and assembly to adjust the installation position of the guide wheel 211 during the process. This method improves the installation accuracy and simplifies the operation process, so that the wire core a1 can be aligned with the center hole of the mold core more easily and accurately, avoiding the problem of wire core eccentricity, thereby avoiding uneven cable coating and improving the service life of the cable.

[0068] The setting of the first dial, the second dial, and the third dial, as well as the setting of the first reference mark, the first scale line, the second scale line, the second reference mark, the third scale line, and the third reference mark in Example 1 further improves the alignment of the wire core a1 with the center hole of the mold core, making the cable wrapping more uniform.

[0069] By setting the structure of the base mechanism 23, the moving mechanism 22 can be easily disassembled and assembled, and the entire moving mechanism 22 can be moved to avoid the process of the wire core a1 penetrating into the wire core sheathing unit 10.

[0070] By providing the auxiliary wheel 213, the wire core a1 is made more stable on the guide wheel 211, thereby avoiding the shaking of the wire core, thereby improving the stability of the wire core a1 passing through the center hole of the mold core, thereby improving the covering effect of the cable.

When the guide wheel 211 needs to carry the wire core a1 of a predetermined specification, the first hand wheel 2213 is rotated to allow the first slider to slide until the first scale mark corresponding to the predetermined specification is aligned with the first reference mark. At this time, the guide wheel 211 is in a first pre-alignment position corresponding to the alignment position in the forward direction, indicating that the guide wheel 211 is currently in the alignment position in the forward direction;

[0074] The second slider 2222 is provided with a second reference mark, and the second slide rail 2221 is provided with various second scale marks corresponding to different specifications of the wire core a1. When the guide wheel 211 needs to carry the wire core a1 of a predetermined specification, the second hand wheel 2223 is rotated to slide the second slider 2222 to the second scale mark corresponding to the predetermined specification and to align with the second reference mark. At this time, the guide wheel is in a second pre-alignment position corresponding to the alignment position in the vertical direction, indicating that the wire core a1 currently carried on the guide wheel 211 is aligned with the center hole of the mold core in the vertical direction.

[0075] The third slider 2232 is provided with a third reference mark, and the third slide rail 2231 is provided with third scale lines corresponding to different specifications of the wire core. When the guide wheel needs to carry a wire core a1 of a predetermined specification, the third hand wheel 2233 is turned to allow the third slider 2232 to slide until the third scale line corresponding to the predetermined specification is aligned with the third reference mark. At this time, the guide wheel 211 is in the third pre-alignment position corresponding to the alignment position in the left and right directions, indicating that the wire core a1 currently carried on the guide wheel 211 is aligned with the center hole of the mold core in the left and right directions.

[0081] <Example 3>

[0082] For the sake of convenience, the same symbols are given to the same structures as those in the first embodiment in this embodiment, and the same descriptions are omitted. In order to make it easier and more accurate to align the wire core a1 with the center hole of the mold core, the following solution can also be adopted:

When the two groups of red light rays are irradiated on the wire core a1, it indicates that the wire core a1 currently carried on the guide wheel 211 is aligned with the center hole of the mold core in the up and down directions and the left and right directions.

[0084] Working principle of the cable manufacturing equipment in Example 3:

[0085] In the third embodiment, during the process of aligning the guide wheel 211 with the center hole of the mold core, the second hand wheel 2223 and the third hand wheel 2233 are rotated so that the wire core carried on the guide wheel 211 is illuminated by two groups of red light respectively, indicating that the current wire core a1 is aligned with the center hole of the mold core.

[0086] Functions and Effects of Embodiment 3

[0087] In the second embodiment, because there are two groups of laser emitters, and two groups of intersecting red light rays are emitted, the intersection point is located at the axial position of the center hole of the mold core.

[0092] The guide wheel mechanism 21 also includes at least one tensioning wheel 214 and an upper bracket (not shown in the figure). Figure 8A tensioning wheel 214 is installed on the upper bracket, and the upper bracket is slidably installed on the guide wheel bracket 212.

[0093] Reference Fig. 9 There are two tensioning wheels 214, and the two tensioning wheels 214 are installed on the upper bracket.

[0095] Functions and Effects of the Embodiments

[0096] The setting of the tension wheel 214 in the fourth embodiment further makes the wire core a1 more stable on the guide wheel 211, avoids the shaking of the wire core, and thus improves the stability of the wire a1 passing through the center hole of the mold core, thereby improving the coating effect of the cable; Figure 8 and Fig. 9 Regardless of whether the wire core is above or below the guide wheel before entering the guide wheel mechanism 21, the setting of the tensioning wheel 214 is suitable for the wire core a1 to pass through the guide wheel mechanism stably.

[0100] The difference from the above embodiment is: Fig.10 The guide groove 2111 has an arc bottom surface with a radius of R1 and two inclined side surfaces which are tangent to the arc bottom surface and extend upward on both sides in a V-shape. When the guide wheel carries a wire core with a diameter of D and D≤2R1, the position of the second scale line corresponding to the wire core is set based on the diameter D.

[0101] That is to say, when the wire core a1 is aligned with the center hole of the mold core, the height of the lowest point of the guide groove plus the height of D / 2 is equal to the height of the center hole axis; when the guide wheel carries a wire core with a diameter of D and D>2R1, the position of the second scale line corresponding to the wire core is set based on the radius R1, the angle α between the two oblique sides and the diameter D. For example, the height of the wire core a1 from the lowest point of the guide groove is H, H = (D-2R1) / (2*sinα / 2)+R1. That is, when the wire core a1 is aligned with the center hole of the mold core, the height of the lowest point of the guide groove plus the height of H is equal to the height of the center hole axis.
