Description

[Technical field]

[0001] The utility model relates to the technical field of optical cable manufacturing, in particular to a cable reel take-up mechanism with a reserved end in a cable reel. [Background Technology]

[0002] The patent with announcement number CN218595797U discloses a cable drum take-up device, which has a cable end clamping mechanism that cooperates with an active top and a pneumatic clamp. The basic implementation method is that the wire feeding member moves along the slide toward the cable drum, feeds the front end of the cable into the threading hole of the cable drum, controls the cable end clamping mechanism located in the cable drum to clamp the cable end, then, the wire feeding member retracts, and finally drives the cable drum to rotate through the clamping disc actuator to complete the take-up.

[0003] However, cables, especially optical cables, need to reserve a certain length (generally 1m to 1.5m) of ends, which can be pulled out after winding into a coil, to facilitate factory qualified inspection and pre-laying inspection. The above-mentioned patent does not mention the implementation method of end reservation, and its mechanism cannot complete the qualified and effective cable end reservation work. In addition, there is currently no relevant equipment or patent disclosed on the market that can automatically complete the cable end reservation.

[0004] In general manual work, the cable head is first passed through the wire hole of the cable drum side plate, pulled out 1m to 1.5m, and wound around the wire storage plate outside the cable drum side plate, and the end is fixed with strong tape or other methods. Therefore, the reserved length of the end manually is unstable, the end fixing method is unreliable, time-consuming, and there are safety issues.

[0005] The optical cable has a single or multiple optical fibers built in. When in dynamic state (under tension), the minimum bending radius of the optical cable is 20 times the cable diameter, and when in static state (free state), the minimum bending radius of the optical cable is 10 times the cable diameter. If the bending radius is too small, the optical fiber will be damaged and the optical cable will be scrapped, causing great economic losses.

[0006] Therefore, it will be of great significance if the end length reservation work before the optical cable is manually performed can be effectively replaced without damaging the optical cable. [Contents of the utility model]

The cable clamping fingers are not limited to pneumatic or electric. When opened, the cable can pass freely. When clamped, it can reliably clamp the cable without damaging the outer skin of the cable. The cable clamping fingers are built into the tapered hole inside the active top and installed at the lateral opening of the active top. The installation direction is parallel to the square of the lateral opening.

[0059] The driven end of the take-up is mainly composed of a driven top and a driven guide shaft. The outer diameter of the active top matches the center hole of the cable drum to ensure that it can be smoothly inserted into the center hole of the cable drum. It is installed on the driven guide shaft through a bearing and can rotate relative to the driven guide shaft when the cable is taken up. The driven guide shaft is not limited to using pneumatic or electric drive, and can clamp the cable drum.

[0060] The traction wire feeding mechanism is mainly composed of a traction belt pulley and its driving mechanism, a wire tube, a base and its sliding device. The traction belt and its driving mechanism can push the cable forward, through the wire tube, and into the cable drum. The traction belt and its driving mechanism, as well as the wire tube, are all installed on the base. Under the guidance and drive of the sliding device, the wire tube can also move forward, insert into the lead-in hole of the cable drum, and approach the cable clamping finger in the active top.

[0061] The cable drum is not limited to an integrated plastic cable drum or a wooden cable drum, and the drum body of the cable drum has a lead-in hole near the inner side.

[0062] When in use, the lead-in hole on the cable drum faces the wire tube, and the active and passive ends of the take-up clamp the cable drum. The traction and wire feeding mechanism slides forward as a whole until the wire tube is inserted into the cable drum through the lead-in hole and approaches the cable clamping finger in the active top. The traction belt pushes the cable forward, and the cable passes through the opening of the cable clamping finger, and is then guided by the conical hole in the active top, and is coiled in the cable drum body in a free and tension-free state until the required 1-1.5m end reserve length is reached. At this time, the cable is still between the cable clamping fingers, and the cable clamping fingers clamp the cable. The active end of the take-up drives the cable drum to rotate, and the subsequent cable take-up work is carried out. At this point, the end reserve work before the cable is taken up is automatically completed.

[0063] The utility model mainly utilizes the inherent flexibility of the cable (optical cable) and adopts the method of pushing (spitting) to feed the cable (optical cable) into the cable drum body. After reaching a certain length, it is clamped by a finger cylinder to complete the work of reserving the end inside the cable drum. Its core technical structure is the shape structure of the active top and the installation position of the cable clamping finger on it. The purpose of the inner cone hole of the active top is to guide, that is, to guide the spitted cable toward the large space area of ​​the drum body. The installation position of the cable clamping finger is eccentrically close to the lateral opening of the active top. Under the joint action of the above core technical methods and technical structures, the cable (optical cable) has a sufficiently large bending radius during the process of spitting and coiling in the drum body without causing damage or scrapping of the optical cable.
