Description

Technical Field

[0001] The utility model relates to the technical field of optical cable production, in particular to a sleeve forming device for optical cable production. Background Art

[0002] Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. It is mainly composed of optical fibers (glass fibers as thin as hair) and plastic protective sheaths and plastic outer skins. A certain number of optical fibers form a cable core in a certain way, which is covered with a sheath and some are also covered with an outer sheath to realize a communication line for optical signal transmission. The basic structure of the optical cable is generally composed of several parts such as a cable core, reinforcing steel wire, filler and sheath. The sheath usually needs to be processed and formed using a sheath forming device.

[0003] As disclosed in the Chinese patent: A fiber optic cable casing forming and processing device, application number: CN202110544784.4, including a feeding mechanism, a control mechanism is movably provided on one side of the feeding mechanism, a forming mechanism is fixedly provided on the top of the control mechanism, a cooling mechanism is movably provided on one side of the forming mechanism, a wiping mechanism is movably provided on one side of the cooling mechanism, and a traction mechanism is movably provided on one side of the wiping mechanism. By setting up the feeding mechanism, the cover plate is driven to slide through the slide groove, and the inclined bottom wall at the bottom is set to facilitate the introduction of plastic particles into the feeding tube, and then the plastic particles at the lower part are guided to the higher end of the feeding tube through the action of the spiral lifting plate, and the plastic particles are introduced into the interior of the upper and lower feeding funnel of the forming mechanism, thereby avoiding the inconvenience of traditional feeding, and facilitating the feeding operation of the user, saving the difficulty of operation, facilitating its use, and improving its usability.

[0004] However, in the above technical solution, when the sleeve is processed and formed by the sleeve forming device, it is necessary to use a cooling device to cool the sleeve. Among them, the cooling water tank is mostly used for sleeve cooling due to its low cost and environmental protection. The sleeves of different materials have different requirements for the length of the cooling equipment (cooling water tank). If the cooling water tank is too long, the tensile force on the sleeve will increase accordingly, which may cause the pipe to rupture or deform. If the cooling water tank is too short, the temperature of the coolant will be too high, affecting the cooling effect. The length of the cooling equipment on the market today is mostly fixed, and the length of the cooling equipment cannot be freely adjusted according to the different sleeve materials, and the scope of use is relatively narrow. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The main purpose of the utility model is to provide a casing forming device for optical cable production, which can effectively solve the problem in the background technology that when the casing is processed and formed by the casing forming device, a cooling device needs to be used to cool the casing. The cooling water trough is low in cost and environmentally friendly, and is mostly used for casing cooling. Casings of different materials have different requirements on the length of the cooling equipment (cooling water trough). If the cooling water trough is too long, the tensile force on the casing will increase accordingly, which may cause the pipe to rupture or deform. If the cooling water trough is too short, the temperature of the coolant will be too high, affecting the cooling effect. The length of the cooling equipment on the market today is mostly fixed, and the length of the cooling equipment cannot be freely adjusted according to the different casing materials, resulting in a relatively narrow range of use.

DETAILED DESCRIPTION

[0025] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the expansion water baffle 6 includes a water baffle base 601, a plurality of limit sliders 602 are arranged on the outer wall of one side of the water baffle base 601, a plurality of second slide grooves 603 are arranged on the inner wall of one side of the inner cavity bottom surface of the water baffle base 601, and a sliding baffle 604 is arranged in the second slide groove 603;

A guide wheel mounting groove 607 is provided on one side of the bottom surface of the second slide groove 603, and a sealing layer 608 is provided on the inner wall of the guide wheel mounting groove 607. When it is necessary to adjust the position of the expanded water baffle plate 6 according to the material of the casing, the movable block 7 is first moved to move the movable block 7 in the direction away from the cooling device 4, and then the movable block 7 drives the water baffle plate base 601 to move, so that the length of the cooling device 4 is adjusted by adjusting the position of the water baffle plate base 601, so that the length of the cooling device 4 can be adjusted according to different casing materials. Subsequently, the grooves 606 are used to move part of the sliding baffle plate 604 so that the sliding baffle plate 604 no longer closes part of the guide wheel mounting groove 607, and then the guide wheel mounting groove 607 is used to fix the redundant guide wheel 11 It is fixedly installed in the inner cavity of the water baffle base 601, and then the coolant is injected into the inner cavity of the cooling device 4 and the water baffle base 601.
