Description

[Technical field]

[0001] The utility model relates to the technical field of optical fiber cables, in particular to an optical cable opening and unwinding device with adjustable tension and cut-in angle. [Background Technology]

[0002] During the construction and laying of optical cables, cable stripping is a key step. This key step can be completed with some additional tools, such as cable cutters and other tools. However, due to the complex environment of the construction site, there are often no such tools to support the stripping of optical cables, so the optical cable must be designed with a cable stripping rope to strip the optical cable. In summary, the cable stripping rope plays an increasingly important role in the design of optical cables.

[0003] At present, in the design and manufacture of optical cables, one or two cable opening ropes are often added under the sheath or steel belt. In order not to affect the cable opening effect of the optical cable, the cable opening ropes should be placed away from some reinforcing ribs in the sheath, such as FRP, in some cases. At this time, the one or two cable opening ropes must be ensured to maintain a certain entry angle when entering the machine head during the production process, and even the design of the two cable opening ropes must further ensure that the two ropes present a certain angle to each other when entering the machine head. The above requirements greatly increase the difficulty in the manufacturing process of the optical cable.

[0004] It can be seen from this that it is very necessary to design a device that can solve the above problems, ensure that the cable opening can achieve a full cable opening effect, and enable the cable opening to enter the machine head at the designed angle, and it is worthy of promotion and application. [Contents of the utility model]

[0005] The purpose of the utility model is to solve the above-mentioned deficiencies and provide an optical cable opening and unwinding device with adjustable tension and cutting-in angle, which can not only control the cutting-in angle of the opening cable entering the machine head according to the design of the optical cable stripping requirements, but also further ensure that the opening cable is stable in the cable to ensure the designed angle, and integrates the adjustable tension design of the opening cable, which is convenient and quick to operate.

[0006] In order to achieve the above-mentioned purpose, a cable opening and releasing device with adjustable tension and cutting-in angle is designed, comprising a metal disc 1, an angle scale panel 3 is arranged on the metal disc 1, a cable core threading shaft hole 7 is arranged in the central area of ​​the angle scale panel 3, and a rotating pointer 5 is riveted through the cable core threading shaft hole 7, a pointer threading hole 2 is arranged at the end of the rotating pointer 5, the opening cable passes through the pointer threading hole 2, and the cutting-in angle is adjusted by swinging the rotating pointer 5, a supporting threaded rod 11 is installed on the metal disc 1, a supporting panel 6 is installed at one end of the supporting threaded rod 11, a guide wheel panel 8 is fixedly connected to the other side of the supporting panel 6, and the guide wheel panel 8 is connected to the supporting The support panel 6 forms a T-shaped structure, and a panel threading hole 4 is opened on the support panel 6. The panel threading hole 4 is used for the opening cable to pass through. A guide wheel panel groove 14 is provided in the guide wheel panel 8. The guide wheel panel groove 14 is extended along the length direction of the guide wheel panel 8. A tension guide wheel 12 is installed in the guide wheel panel groove 14. There are two tension guide wheels 12. Both tension guide wheels 12 are movable along the guide wheel panel groove 14, and the tension of the opening cable can be controlled by adjusting the distance between them. A circle of tension guide wheel recessed groove 13 is provided on the outer circumferential surface of the tension guide wheel 12. The tension guide wheel recessed groove 13 allows the opening cable to be stuck in the tension guide wheel 12 to prevent it from slipping out.

[0007] Furthermore, an angle scale panel 3 is arranged at the center of the metal disc 1. A 360° scale is engraved on the angle scale panel 3. The scale is used to express the angle degree, and the minimum scale unit is 6°. Therefore, the cable opening angle can be controlled vividly and simply according to the indication on the scale panel.

[0008] Furthermore, the tension guide wheel 12 is installed in the guide wheel panel groove 14 through the guide wheel threaded rod 10, a locking nut 9 is screwed onto the guide wheel threaded rod 10, and the tension guide wheel 12 is locked and fixed on the guide wheel panel 8 through the locking nut 9.

[0009] Furthermore, the tail end of the supporting threaded rod 11 is provided with a thread, and is tightened and fixed to the machine head through the thread, and the supporting threaded rod 11 and the metal disc 1 and the supporting panel 6 are all locked and fixed through a locking nut 9.

[0010] Furthermore, the support panel 6 and the guide wheel panel 8 are integrally cast and are both made of metal material, thereby playing a role in stabilizing the device.

[0011] Furthermore, the opening cable is wound on two tension guide wheels 12 in an "8" shape, so that the opening cable will have a certain tension when entering the cable core. This certain tension is used to support the stability of the cutting angle of the opening cable into the cable core.

[0012] Furthermore, two rotating pointers 5 are provided, namely rotating pointer 1 501 and rotating pointer 2 502 , and the ends of rotating pointer 1 501 and rotating pointer 2 502 are provided with pointer threading hole 1 201 and pointer threading hole 2 202 respectively.

[0013] Furthermore, the support panel 6 includes a support panel 1 601 and a support panel 2 602, and the support panel 1 601 and the support panel 2 602 are arranged vertically and parallel to each other, and the support panel 1 601 and the support panel 2 602 are respectively fixedly connected to the metal disc 1 by at least two supporting threaded rods 11, and the support panel 1 601 and the support panel 2 602 are respectively provided with a panel threading hole 1 401 and a panel threading hole 2 402.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] (1) The utility model can realize the real controllable entry of the cable opening rope into the cable core, and can enter the cable core according to the predetermined design angle, thereby avoiding the situation in which the cable opening rope accidentally sinks into the cable wrapping tape or overlaps with the parallel reinforcement members in the sheath, such as FRP, when entering the cable core due to the instability of the traditional pay-off frame or the uncontrollable cutting angle during the manufacturing process, resulting in the cable opening being not smooth or more seriously, the cable opening failing, causing unnecessary losses;

[0017] (2) The utility model can realize how to accurately present 180° diagonal angles for two open cables, so as to achieve the purpose of half-opening of the optical cable. The two rotating pointers rotate respectively on the upper and lower circumferences of the circle, and can control the angle between the two open cables in a simple and vivid way according to the indications on the scale panel. In traditional production and manufacturing, when there is a problem of the angle between the two open cables, it is often necessary to adjust the cut-in angle of the open cable individually, and it is a "blind adjustment". As long as one cut-in angle is not adjusted in place, it is necessary to repeatedly debug multiple times, which is time-consuming and labor-intensive, and will also cause unnecessary debugging waste;

[0018] (3) The utility model integrates a tension-bearing pay-off mechanism for the open cable, which is realized by winding the open cable in an "8-shaped" manner on the tension guide wheel. In this way, the open cable will have a certain tension when entering the cable core. This certain tension is used to support the stability of the cutting angle of the open cable into the cable core. In the production process of optical cables, since the cable core often enters the machine head for cabling with a twisted intercept, such rotation will disturb the position of the open cable in the cable, which brings great difficulties and challenges to the requirements of the cutting angle of the open cable and the angle between the two open cables. The utility model directly integrates the tension, which is simple to produce and easy to operate;

[0019] (4) The utility model integrates an adjustable cable tension design, and the cable tension is controlled by the distance between the two tension guide wheels in the guide wheel panel. In particular, there is a hollow guide wheel groove in the guide wheel panel, and the distance is controlled and fixed by passing the tension guide wheel and a locking nut. The greater the distance between the two, the greater the tension. On the contrary, the smaller the distance between the two, the smaller the tension. Compared with the traditional tension pay-off device, the utility model is simple in design, convenient and quick in operation, and the learning cost of the operator is relatively low;

[0020] (5) The device of the utility model can be directly installed at the rear of the extruder head without the need for an additional support frame. The tail thread of the supporting threaded rod is directly screwed to the head to tighten and fix it with the head. Compared with the traditional wire release device, the utility model occupies a small space and can be used in various production line environments. It does not rely on the support of other auxiliary equipment. It can also be quickly disassembled and sorted for storage during the equipment shutdown stage;

[0021] (6) The utility model can not only control the cutting angle of the cable rope entering the machine head according to the design of the optical cable stripping requirements, but also further ensure that the cable rope is stable in the cable to ensure the designed angle, and an additional tension adjustment device is provided. The structural design is unique and novel, and can be fully promoted to various production lines to directly replace the traditional cable rope release device, and also has other special functions, achieving the design effect;

[0022] In summary, compared with traditional cable opening and releasing devices, the utility model has functions and operational conveniences that traditional cable opening and releasing devices cannot achieve, which are mainly reflected in the following points: First, the utility model can accurately control the cutting angle of the cable opening in the cable core, and can be visualized, simple and easy to operate, which is of positive significance in some scenarios with special requirements for cable opening; second, it has tension and adjustable tension, and this function is modularly integrated in the device of the utility model, and the operation is easy to understand and simple; third, the equipment can be directly connected to the machine head, so it can be miniaturized, will not take up additional equipment placement space, and has strong installation flexibility.

The angle scale panel 3 is set at the center of the metal disc 1, and the angle scale panel 3 is engraved with a 360° scale. The scale is used to express the angle degree, and the minimum scale unit is 6°, so that the cable angle can be controlled vividly and simply according to the indication on the scale panel. The support panel 6 and the guide wheel panel 8 are cast as a whole, and are both made of metal material, so as to play the role of stabilizing the device. The opening cable is wound around two tension guide wheels 12 in an "8" shape, so that the opening cable will have a certain tension when entering the cable core. This certain tension is used to support the stability of the cutting angle of the opening cable into the cable core.

[0034] The utility model mainly includes a metal disc 1, an angle scale panel 3, a rotating pointer 5, a pointer threading hole 2, a cable core threading shaft hole 7, a locking nut 9, a support threaded rod 11, a support panel 6, a panel threading hole 4, a guide wheel panel 8, a guide wheel threaded rod 10, a tension guide wheel 12, a tension guide wheel recessed groove 13 and a guide wheel panel groove 14, which are specifically described as follows:

[0035] The metal disc 1 is circular and serves as a base panel.

[0036] The angle scale panel 3 is located at the center of the metal disc 1 and is engraved with 360° scales to express the angle degree, with a minimum unit scale of 6°.

[0038] Pointer threading hole 2, the diameter of which is about 3mm, the cable opening rope directly enters the machine head through the threading hole. In addition, the 3mm hole size appropriately limits the swing of the cable opening rope and avoids a large error in the cutting-in angle. Since the cutting-in angles of two cable opening ropes are supported, there are two pointer threading holes 1 201 and pointer threading hole 2 202.

[0044] The support threaded rod 11 is designed with four support threaded rods in total. These four support threaded rods are mainly used to connect the metal panel 1 and the support panel 6 to achieve complete stability of the device. The tail end of the support threaded rod 11 has a threaded design, which can be directly screwed to the diverter cone at the rear seat of the machine head, so that the utility model device does not need to rely on other bases or frames for fixing or support.

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0048] As attached Figure 1As shown, the utility model provides an optical cable opening and unwinding device with adjustable tension and cut-in angle, which includes a metal disc 1, an angle scale panel 3, a rotating pointer 5, a pointer threading hole 2, a cable core threading shaft hole 7, a locking nut 9, a support threaded rod 11, a support panel 6, a panel threading hole 4, a guide wheel panel 8, a guide wheel threaded rod 10, a tension guide wheel 12 and a tension guide wheel recessed groove 13. In brief, the utility model device is composed of five module components spliced ​​together. The area where the metal disc 1 is located belongs to a module part, the support panel 6 and the guide wheel panel 8 form a module area, the tension guide wheel 12 belongs to a module area, the support threaded rod 11 and the locking nut 9 are a module area, and finally the guide wheel threaded rod 10 and the locking nut 9 are a module area. The following specifically explains these five areas in detail and expounds on the idea of ​​the utility model.

[0049] As attached Figure 2 As shown, this is one of the module areas and also one of the key design components of the utility model patent. An angle scale panel 3 is engraved on the metal disc 1, and a cable core threading shaft hole 7 is designed in the central area of ​​the disc. A rotating pointer 5 is connected to the shaft hole. There are two pointers in total. Both pointers have pointer threading holes 2. The cable is passed through the pointer threading holes, and the swing of the rotating pointer is used to achieve the function of controllable entry angle. The angle scale panel divides the circumference of 360° into various scale units, and the minimum scale unit is 6°. This visualized creative utility model can simply and clearly observe the entry angle of the cable into the cable core, so as to achieve precise control of the process.

[0050] As attached Figure 3 As shown, this is one of the module areas, which serves as a tension guide wheel bracket, and consists of support panel 1 601 and support panel 2 602, guide wheel panel 1 801 and guide wheel panel 2 802, guide wheel panel slot 1 1401 and guide wheel panel slot 2 1402, panel threading hole 1 401 and panel threading hole 2 402. The composition of the above devices is the structural basis for ensuring that the tension of the cable can be adjusted and the cable can reach the metal scale disk, and is the basic framework for achieving adjustable tension.

[0051] As attached Figure 4 As shown, specifically, it is an assembly diagram of the tension guide wheel 12 and the guide wheel panel groove 14, which is also a top view. In the figure, the inner groove 13 of the tension guide wheel can be shown, and the cable can be designed to be stuck in the tension guide wheel so that it cannot slide out of the guide wheel to ensure stable production; the distance between the tension guide wheels is the key to controlling the tension of the cable. The greater the distance between the two tension guide wheels, the tighter the cable will be, and the greater the tension. On the contrary, the smaller the distance, the smaller the cable will be; according to the above mechanism, the guide wheel panel groove plays its role, which enables the tension guide wheel to move freely within a certain distance.

[0052] As attached Figure 5 FIG. 1 is a schematic diagram of a supporting threaded rod 11 and a locking nut 9, which is used to connect the supporting panel and the metal disc 1 to form a whole.

[0053] As attached Figure 6 The figure shows a schematic diagram of the guide wheel threaded rod 10 and the locking nut 9, which is used to relatively fix the tension guide wheel 12 at a certain distance to achieve the purpose of adjustable tension.

[0054] As attached Figure 7 As shown, a schematic diagram of the routing of the open cable is shown, which passes through the tension guide wheel 12, the panel threading hole 4, the pointer threading hole 2, and then directly enters the cable core. This series of routing diagrams clearly and accurately summarizes the working principle of the utility model device.

[0055] In summary, the utility model is an auxiliary device for optical cable manufacturing equipment with innovation, integration and wide applicability, which fully demonstrates the utility model idea of ​​an optical cable opening and releasing device with adjustable tension and cutting angle, and achieves the design result.
