Description

Technical Field

[0001] This utility model relates to the field of quick wire changing technology for wire feeding frames, and in particular to a quick wire changing device for a cable-making machine wire feeding frame. Background Technology

[0002] The cable laying frame is the core component of the cable forming machine. It is mainly used to support the cables, such as monofilaments, insulated cores, stranded wires, etc., and to release the cables at a set speed and tension during the cabling process. This provides a stable supply of wire for subsequent stranding and cabling processes. Its performance directly affects the quality of the cabling, such as stranding pitch, tension uniformity, and production efficiency.

[0003] The applicant discovered through a search that a Chinese patent, "A Quick Cable Changing Device for Radio Frequency Cables," with publication (announcement) number "CN212784144U," mainly describes a device that allows for the removal of a support frame and the unfolding of a tripod when the radio frequency cable changing distance is long. This allows the radio frequency cable to be secured to the cable elastic fixing buckle above the support frame. By pulling a telescopic rod, the height of the cable elastic fixing buckle can be adjusted, providing stable support for the cable and eliminating the need for manual support during the changing process. This significantly reduces the number of personnel required for cable changing operations and improves efficiency. However, the device requires replacement when the old cable reel runs out of wire, which is time-consuming, cumbersome, and inefficient. Therefore, we propose a quick cable changing device for a cable laying frame on a cabling machine. Utility Model Content

[0004] The purpose of this utility model is to provide a quick wire changing device for a cable-laying machine's wire-laying frame, in order to solve the problem mentioned in the background art that when the wire on the old wire spool on the device runs out, it needs to be replaced, which is not only time-consuming and cumbersome, but also delays work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-change device for a cable-forming machine's pay-off frame, comprising a cable reel, on which a changing component and a pressing component are provided. The changing component includes a linear reciprocating motor, one end of which is provided with a bonding plate, and the right side of which is provided with a first fixing plate. The first fixing plate is fixedly installed on the cable-forming machine. A magnetic powder brake is provided on the left side of the bonding plate, and a connecting sleeve is slidably connected to the magnetic powder brake. A limiting plate arranged in a circular array is fixedly installed on the outer circumferential surface of the connecting sleeve. A rotating shaft is slidably connected to the limiting plate and the connecting sleeve, and a rotating groove is provided on the surface slidably connected to the rotating shaft. Two sets of second support plates are rotatably connected to the outer circumferential surface of the rotating shaft, and the side of the rotating shaft away from the magnetic powder brake is bonded to the right side of the cable reel.

[0006] As a preferred embodiment, the lower end of the second support plate is slidably connected to a base plate, the lower end of the base plate is fixedly installed with a cable forming machine, the upper end of the base plate is fixedly installed with a first support plate, and the above and the second support plate are symmetrically distributed. The right side of the first support plate is rotatably connected to a first connecting rod, the right side of the first connecting rod is fixedly installed with a first rotating rod, and the right side of the first rotating rod is attached to the other side of the spool.

[0007] As a preferred embodiment, a rotating platform is fixedly installed at the rear end of the base plate, and a DC motor is provided at the lower end of the rotating platform and located on the rotating shaft of the DC motor. The lower end of the DC motor is detachably connected to the cable forming machine.

[0008] As a preferred embodiment, a support rod is attached to the lower end of the base plate, and the lower end of the support rod is fixedly installed inside the cable-making machine.

[0009] As a preferred embodiment, the extrusion assembly includes an extrusion plate, with second connecting rods fixedly installed on the left and right sides of the extrusion plate, a fourth fixing plate fixedly installed at the end of the second connecting rod away from the extrusion plate, a hydraulic rod provided at the lower end of the fourth fixing plate, a third fixing plate provided at the lower end of the hydraulic rod, a second fixing plate fixedly installed on one side of the third fixing plate, and the lower end of the second fixing plate fixedly installed on the cable forming machine.

[0010] As a preferred embodiment, fixing rods are fixedly installed on the left and right sides of the second fixing plate. A sliding groove is provided on the side of the fixing rod near the second fixing plate. A pressure sensor is installed inside the sliding groove and is electrically connected to the cable forming machine. A slider is slidably connected to the side wall of the sliding groove. A floating roller is detachably connected to one side of the slider. A guide rail is attached to the outer circumference of the floating roller. A snap-fit ​​plate is provided at the front end of the guide rail and is mounted on the cable forming machine. A placement groove is provided at the upper end of the guide rail, and a connecting pipe is attached to the rear end of the guide rail.

[0011] The technical effects and advantages of this utility model are as follows: The magnetic powder brake can be quickly separated from or attached to the rotating shaft by pushing the bonding plate with a linear reciprocating motor. The sliding design of the limiting plate and the rotating groove allows the rotating shaft to quickly detach from the wire spool, greatly shortening the wire changing time. During use, the magnetic powder brake can drive the parts on it to work. The tension can be adjusted during operation. The combination structure of the connecting sleeve and the limiting plate ensures stable transmission of the rotating shaft and simplifies the disassembly steps. The second support plate slides along the base plate. Combined with the bonding design of the first rotating rod and the wire spool, it can adapt to wire spools of different specifications. The rotating table and DC motor can flexibly adjust the wire feeding angle. The support rod strengthens the load-bearing capacity of the base plate. The hydraulic rod pushes the extrusion plate to move linearly along the second connecting rod, which can quickly achieve insulation piercing and crimping connection between the new and old wires on the wire reel in the connecting tube. With the stable support of the fourth fixed plate, the extrusion process is ensured to be precise and controllable. The close fit design of the floating roller and the guide rail keeps the cable under constant tension during transmission. When the cable tension changes, the floating roller slides along the sliding groove and triggers the pressure sensor to adjust the wire feeding speed in real time. The connecting tube and placement groove at the rear end of the guide rail provide guidance and buffer space for the cable. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 To be continued Figure 3A quick-change device for a cable-forming machine's pay-off frame includes a cable reel 1. The cable reel 1 is equipped with a change-up component 2 and a pressing component 3. The change-up component 2 includes a linear reciprocating motor 206. One end of the linear reciprocating motor 206 is fitted with a bonding plate 207. A first fixing plate 205 is located on the right side of the linear reciprocating motor 206. The first fixing plate 205 is fixedly installed with the cable-forming machine. A magnetic powder brake 211 is located on the left side of the bonding plate 207. A connecting sleeve 215 is slidably connected to the magnetic powder brake 211. A limiting plate 216 arranged in a circular array is fixedly installed on the outer circumferential surface of the connecting sleeve 215. A rotating shaft 213 is slidably connected to the limiting plate 216 and the connecting sleeve 215. A rotating groove 214 is opened on the surface slidably connected to the rotating shaft 213. Two sets of second support plates 212 are rotatably connected to the outer circumferential surface of the rotating shaft 213. The side of the rotating shaft 213 away from the magnetic powder brake 211 is fitted and connected to the right side of the cable reel 1.

[0016] The circular array of limiting plate 216 and connecting sleeve 215 has a rotating groove 214 on the surface where the rotating shaft 213 slides with the connecting sleeve 215, which facilitates the rotation of the parts on it. The magnetic powder brake 211 can work in conjunction with the cable forming machine without having to readjust the tension of the new line when changing the line.

[0017] The lower end of the second support plate 212 is slidably connected to the base plate 204. The lower end of the base plate 204 is fixedly installed with the cable forming machine. The upper end of the base plate 204 is fixedly installed with the first support plate 202, which is symmetrically distributed with the second support plate 212. The right side of the first support plate 202 is rotatably connected to the first connecting rod 203. The right side of the first connecting rod 203 is fixedly installed with the first rotating rod 201. The right side of the first rotating rod 201 is attached to the other side of the coil 1.

[0018] The upper ends of the same base plate 204 are respectively fixed with the second support plate 212 and the first support plate 202, and the second support plate 212 and the first support plate 202 are symmetrically distributed. On the surface where the first rotating rod 201 is in contact with the coil 1, the protruding rod on the first rotating rod 201 slides in the original hole or groove of the coil 1, which is convenient for limiting the position of the coil 1.

[0019] A rotating platform 210 is fixedly installed at the rear end of the base plate 204. A DC motor 209 is provided at the lower end of the rotating platform 210 and is located on the rotating shaft of the DC motor 209. The lower end of the DC motor 209 can be detachably connected to the cable forming machine.

[0020] The rotating table 210 is fixed with two identical base plates 204. The DC motor 209 drives the rotating table 210 and its parts to rotate, which facilitates the replacement of old and new wires and can also replace one of the two sets of wire reels 1.

[0021] A support rod 208 is attached to the lower end of the base plate 204, and the lower end of the support rod 208 is fixedly installed inside the cable forming machine.

[0022] The same support rods 208 are symmetrically distributed with respect to the DC motor 209, which helps to reduce the weight on the base plate 204.

[0023] Specifically, wire reels 1 are installed on the base plates 204 on both sides of the rotating table 210. When the left wire reel 1 is working, the first rotating rod 201 is inserted into the left slot of the wire reel 1 for limiting, and the right rotating shaft 213 is in contact with the wire reel 1. The magnetic powder brake 211 drives the rotating shaft 213 to rotate through the connecting sleeve 215 and the limiting plate 216. Stable wire feeding is achieved with the help of the sliding fit of the rotating groove 214, and the tension is adjusted in real time. When the left wire reel 1 is almost used up, the DC motor 209 is started, which drives the rotating table 210 to rotate 90 degrees, so that the right spare wire reel 1 is switched to the working position. After switching, The linear reciprocating motor 206 pushes the bonding plate 207, allowing the magnetic powder brake 211 to fit tightly against the rotating shaft 213, ensuring that the tension parameter can be adjusted during operation without additional adjustment. When the removed coil 1 needs to be replaced, the linear reciprocating motor 206 is started in reverse, causing the bonding plate 207 to drive the magnetic powder brake 211 to disengage from the rotating shaft 213. The empty coil 1 can be removed by sliding the second support plate 212. The new coil 1 is repositioned by the first rotating rod 201 and the rotating shaft 213 to complete the replacement. The support rod 208 distributes the load of the base plate 204, ensuring stable operation of the device.

[0024] Please see the appendix Figure 4 - Appendix Figure 5 The extrusion assembly 3 includes an extrusion plate 309. Second connecting rods 310 are fixedly installed on the left and right sides of the extrusion plate 309. A fourth fixing plate 311 is fixedly installed at the end of the second connecting rod 310 away from the extrusion plate 309. A hydraulic rod 308 is provided at the lower end of the fourth fixing plate 311. A third fixing plate 307 is provided at the lower end of the hydraulic rod 308. A second fixing plate 306 is fixedly installed on one side of the third fixing plate 307. The lower end of the second fixing plate 306 is fixedly installed on the cable forming machine.

[0025] The same second connecting rod 310 is fixed on the left and right sides of the extrusion plate 309 to make the extrusion plate 309 parallel, and is driven by the hydraulic rod 308 of the same specification to make the extrusion plate 309 extrude the following parts.

[0026] Fixing rods 302 are fixedly installed on the left and right sides of the second fixing plate 306. A sliding groove 314 is provided on the side of the fixing rod 302 near the second fixing plate 306. A pressure sensor 313 is installed inside the sliding groove 314 and is electrically connected to the cable forming machine. A slider 312 is slidably connected to the side wall of the sliding groove 314. A floating roller 305 is detachably connected to one side of the slider 312. A guide rail 303 is attached to the outer circumference of the floating roller 305. A snap-fit ​​plate 301 is provided at the front end of the guide rail 303 and is installed on the cable forming machine. A placement groove 304 is provided at the upper end of the guide rail 303. A connecting pipe 315 is attached to the rear end of the guide rail 303.

[0027] On one side of the fixed rod 302 of the same specification that is fixed to the second fixed plate 306, two sets of sliding grooves 314 of the same size are opened. When the slider 312 slides in it, it drives the parts on it to slide. The pressure sensor 313 is pressed by the slider 312 and works with the cable forming machine to convert gravity into an electrical signal. The snap-fit ​​plate 301 works with the cable forming machine and is combined with the placement groove 304 opened on the guide rail 303. The width of the placement groove 304 is the same as the width of the extrusion plate 309. The connecting pipe 315 can be connected to the new and old cables. When it works with the above-mentioned parts, it can be connected to the new and old cables through insulation piercing crimping, which is convenient for the normal use of the cable.

[0028] Specifically, when the extrusion assembly 3 is working, the new and old cables are introduced through the connecting pipe 315 after being connected by insulation piercing and crimping. They pass through the placement groove 304 of the guide rail 303. The width of the placement groove 304 is the same as that of the extrusion plate 309. The clamping plate 301 limits the cable position. The floating roller 305 is attached to the bottom of the guide rail 303. The sliders 312 at both ends are embedded in the sliding grooves 314 of the fixed rod 302. When the cable tension changes, the floating roller 305 drives the sliders 312 to slide up and down, extruding the pressure sensor 313 in the sliding groove 314. The pressure sensor 313 converts the gravity signal into an electrical signal and transmits it to the cabling machine. The hydraulic rods 308 of the same specification on both sides start synchronously. Through the third fixed plate 307, the fourth fixed plate 311 and the second connecting rod 310, the extrusion plate 309 is driven to descend in parallel. The second fixed plate 306 and the fixed rod 302 provide stable support to ensure accurate extrusion and ensure stable cable transmission.

[0029] Working principle of this utility model: This utility model is a quick wire changing device for a cable-making machine's wire-laying frame. First, the first rotating rod 201 is inserted into the slot of the wire reel 1, and the rotating shaft 213 is attached to the right side of the wire reel 1 to achieve bidirectional positioning. The magnetic powder brake 211 drives the rotating shaft 213 through the connecting sleeve 215 and the circular array limiting plate 216, which, together with the sliding guide of the rotating groove 214, stabilizes the wire laying and adjusts the tension in real time. When the working wire reel 1 is about to run out of wire, the DC motor 209 drives the rotating table 210 to rotate 90 degrees, so that the spare wire reel 1 is switched to the working position. After the switch, the linear reciprocating motor 206 pushes the attachment plate 207, so that the magnetic powder brake 211 is tightly attached to the rotating shaft 213 of the new wire reel 1, and works directly using the original tension parameters without the need for re-tensioning. During the new debugging process, when replacing the reel 1, the reverse start of the linear reciprocating motor 206 disengages the magnetic powder brake 211, and the sliding second support plate 212 allows for disassembly and replacement. The support rod 208 distributes the load to ensure structural stability. The extrusion assembly 3 works synchronously with the cable replacement process. After the new and old cables are connected by insulation piercing and crimping through the connecting pipe 315, they enter the guide rail 303 placement slot 304 and are limited by the snap-fit ​​plate 301. When the cable tension changes, the floating roller 305 drives the slider 312 to move in the sliding groove 314. The extrusion pressure sensor 313 generates an electrical signal, and the hydraulic rods 308 on both sides synchronously drive the extrusion plate 309 to descend in parallel. In conjunction with the floating roller 305, the tension is precisely adjusted to ensure stable cable transmission before and after the cable replacement, achieving efficient non-stop cable replacement.
