Description

Tension control device for pay-off rack of cable reel Technical Field The utility model relates to the technical field of cable paying-off devices, in particular to a tension control device for a paying-off rack of a cable reel. Background In the paying-off process of the existing cable drum paying-off frame, various problems exist for tension control of cables. On one hand, the traditional tension control mode, such as a mode of adopting a band-type brake to control the elasticity of a spring through a hand wheel, has poor tension adjustment accuracy and cannot meet the requirements of high-precision cable laying or production, and on the other hand, the adjustment mode is inconvenient to operate, needs to be adjusted manually frequently, and increases the labor intensity and the working difficulty of workers. The unreeling tension is not accurately measured and controlled, and no visual numerical display exists, so that the adjustment of the cable unreeling tension is greatly influenced by the operation experience of production staff, in principle, a cable product cannot be thinned, and the cable tension needs to be kept stable in the unreeling process. The prior device has the following problems that (1) the coil and the contained cable are not concentric, so that the stability of the unreeling tension is influenced, (2) the friction force of the thimble shaft rolling bearing of the prior cable unreeling machine under the condition of heavy load of the coil can cause the unreeling tension to be unstable, and (3) the acceleration and deceleration of the cable coil and the non-uniform rotation can also have great influence on the unreeling tension, so that the stability of the tension is insufficient, so that the quality of the cable is influenced. Disclosure of utility model The utility model aims to provide a tension control device for a pay-off rack of a cable drum, which solves the technical problem that the tension of a cable unreeling device in the prior art is unstable. The embodiment of the application discloses a tension control device for a pay-off rack of a cable reel, which comprises the following components: a reduction gearbox; The first belt pulley is arranged on an input shaft of the reduction gearbox; the mounting frame is arranged on the reduction gearbox; the air cooling cover is arranged on the mounting frame; the clutch is arranged on the mounting frame and is positioned in the air cooling cover; the second belt pulley is arranged at the output end of the clutch, a belt is arranged between the second belt pulley and the first belt pulley, and the second belt pulley is positioned inside the air cooling cover. According to the embodiment of the application, the clutch is additionally arranged on the reduction gearbox, and braking force is provided by the clutch, so that the cable can be stably and slowly unreeled when being unreeled, and the stability of tension when being unreeled is ensured. Based on the technical scheme, the embodiment of the application can be further improved as follows: further, the mounting frame includes: The bottom plate is connected with the reduction gearbox; The bracket side plate is vertically arranged on the bottom plate and is positioned at the outer side of the air cooling cover, the beneficial effect of adopting this step is that can guarantee the stability after the clutch assembly through the mounting bracket. Further, the clutch is a magnetic powder clutch, and the beneficial effect of the method is that stable braking is realized through the specific clutch. Further, the two ends of the mandrel of the clutch are respectively connected with the side plates of the support, and the stability of the clutch after being assembled can be further guaranteed by adopting the method. Further, a belt pulley spacer ring is arranged between the end part of the second belt pulley and the inner wall of the air cooling cover, and the beneficial effect of the step is that the stable operation of the second belt pulley is prevented from being influenced by other parts such as the air cooling cover. Further, the flange is installed to the tip of clutch, the flange with install elastic pin between the second belt pulley, the beneficial effect that adopts this step is through the stability of elastic pin when can further guarantee the second belt pulley during operation. Further, the belt is a triangular belt, and the stability of torque transmission can be achieved through the triangular belt. Further, the reduction gearbox is a three-shaft two-stage reduction gearbox. One or more technical solutions provided in the embodiments of the present application at least have the following technical effects or advantages: 1. according to the application, the clutch is additionally arranged to provide stable braking force, and the speed reducer is used for amplifying, so that the cable can be slowly and stably unreeled when being unreeled, the tension change amplitude is reduced,
