Technical Field

[0001] The utility model relates to the technical field of aramid yarn equipment, in particular to a tension-adjustable passive aramid yarn pay-off device. Background Art

[0002] At present, the more common optical cables on the market are mostly small outer diameter optical cables. Small outer diameter optical cables usually need to be coated with an aramid layer as their reinforcement layer to improve the overall strength of the optical cable. In the production of optical cables, aramid wire laying needs to be carried out through an aramid wire laying rack.

[0003] The existing aramid yarn pay-off device is difficult to control the tension of the aramid yarn during pay-off, and the aramid yarn is easily over-twisted, causing the internal sleeve to break, affecting the stable production of optical cables. Therefore, it is necessary to develop a device that can stabilize the tension of the aramid yarn during pay-off. Utility Model Content

[0006] The utility model provides an adjustable tension passive aramid yarn pay-off device, comprising a bracket; a turntable, which is rotatably arranged on the upper part of the bracket; a connecting seat, which is fixedly arranged on the upper part of the turntable; and a plurality of winding posts, which are connected to the connecting seat through an elastic mechanism.

[0007] Preferably, the elastic mechanism comprises a telescopic rod and a spring, one end of the telescopic rod is fixedly connected to the connecting seat, and the other end is fixedly connected to the winding post, and the spring is arranged around the outside of the telescopic rod.

[0008] Preferably, a plurality of slide grooves corresponding to the winding posts are provided on the upper portion of the turntable, and the bottom of the winding post is slidably arranged in the slide grooves.

[0009] Preferably, the connection seat is in the shape of a prism, and the number of the prism sides is the same as the number of the winding poles.

[0010] Preferably, a bearing is provided at the center of the upper portion of the bracket, a rotating shaft is provided through the bearing, and the upper portion of the rotating shaft is fixedly connected to the center of the turntable.

[0011] Preferably, the number of the winding poles is not less than 8.

[0012] Technical effects of the utility model:

[0013] Compared with the prior art, the utility model relates to an adjustable tension passive aramid yarn pay-off device, which, by arranging an elastic mechanism, enables the aramid yarn to maintain a stable tension when paying out, thereby ensuring the normal production of the optical cable; by arranging a spring and cooperating with a telescopic rod, the device greatly enhances the control of the tension of the aramid yarn when paying out, and the spring and the telescopic rod are low in cost and have a long service life, which is conducive to the stable production of the optical cable.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings of the present utility model specification.

[0018] Example:

[0019] like Figure 1 , 2 As shown, the embodiment described in this invention is a kind of passive aramid yarn pay-off device with adjustable tension, comprising a bracket 1, which is used to support the device; a turntable 2, which is rotatably arranged on the upper part of the bracket 1, and the upper part of the turntable 2 is provided with eight slide grooves 5 corresponding to the winding poles 4, and the bottom of the winding pole 4 is slidably arranged in the slide grooves 5; a connecting seat 7, which is fixedly arranged on the upper part of the turntable 2, and the shape of the connecting seat 7 is an octagonal prism; eight winding poles 4, which are connected to the connecting seat 7 through an elastic mechanism, and the winding poles 4 are used to wind aramid yarn, and the elastic mechanism is used to adjust the distance between the winding poles 4 and the connecting seat 7 to keep the tension stable when the aramid yarn is paid out; by setting the elastic mechanism, the aramid yarn can keep the tension stably when paying out, thereby ensuring the normal production of the optical cable.

[0020] The elastic mechanism includes a telescopic rod 3 and a spring 6, one end of the telescopic rod 3 is fixedly connected to the connecting seat 7, and the other end is fixedly connected to the winding column 4. The spring 6 is arranged around the outside of the telescopic rod 3. When the spring 6 and the telescopic rod 3 contract, the pay-off tension of the aramid yarn is reduced, and when the spring 6 and the telescopic rod 3 extend, the pay-off tension of the aramid yarn is increased. By arranging the spring 6 to cooperate with the telescopic rod 3, the control of the tension of the aramid yarn during pay-off of the device is greatly enhanced, and the spring 6 and the telescopic rod 3 are low in cost and long in service life, which is conducive to the stable production of optical cables.

[0021] A bearing 8 is provided at the center of the upper portion of the bracket 1 , a rotating shaft 9 is provided through the bearing 8 , and the upper portion of the rotating shaft 9 is fixedly connected to the center of the turntable 2 .

[0022] Specific implementation of this utility model:

[0023] When paying out the aramid yarn, the aramid yarn is wound around the outside of the winding column 4 and then paid out. When the tension of the aramid yarn increases, the spring 6 and the telescopic rod 3 contract. When the tension of the aramid yarn decreases, the spring 6 and the telescopic rod 3 extend to keep the tension of the aramid yarn stable when paying out.

[0024] The above-mentioned specific implementation methods are only specific cases of the present utility model. The patent protection scope of the present utility model includes but is not limited to the product form and style of the above-mentioned specific implementation methods. Any appropriate changes or modifications made to them by ordinary technicians in the relevant technical field in accordance with the claims of the present utility model shall fall within the patent protection scope of the present utility model.
