Tension detection device for wrap yarn production

The utility model discloses a tension detection device for wrap yarn production, which comprises a base, a detection assembly is arranged above the base, and wrap yarn is arranged above the detection assembly. According to the tension detection device for wrap yarn production, through cooperation of the base, wrap yarn and the detection assembly, in the process, a sliding block and a vertical rod can slide upwards in a vertical plate, a tension spring is continuously stretched, and a clamping rod is continuously in one-way clamping connection with an adjacent chute in the period, so that the vertical rod cannot move downwards under the tension of the tension spring after sliding upwards; when the tensile force of the upper end and the lower end of the wrap yarn is larger than the maximum large force bearing strength of the wrap yarn, the wrap yarn can be broken, the lower groove block loses the acting force of upward movement in the period, and then an operator can visually know the strength value of the wrap
