Folding screen bending mechanism and mobile terminal
ActiveCN112788162AExtended service lifeAffect the display effectTelephone set constructionsEngineeringStructural engineering
The invention relates to the technical field of folding screens, and discloses a folding screen bending mechanism and a mobile terminal. The folding screen bending mechanism comprises a supporting seat, a transmission assembly and a stretching assembly; the transmission assembly is arranged on the supporting seat and used for driving the first screen and the second screen to be folded or unfolded so as to enable the bendable part to be bent or unfolded, and the stretching assembly is used for stretching the first screen and the second screen after the bendable part is unfolded so as to flatten the bendable part under tensile force. The mobile terminal comprises the folding screen bending mechanism. The included angle between the first screen and the second screen can be adjusted according to user requirements, the bending radius of the bendable part is prevented from exceeding the limit bending radius limited by a screen material; therefore, the service life of the folding screen is prolonged, and the situation that the display effect of the folding screen and the user experience are affected due to damage caused by long-term excessive bending of the bendable part is avoided. The folding screen can be kept flat and attractive after being flattened in the long-term use process, and the phenomenon that the display effect of the folding screen is affected by bending creases is avoided.

Manufacturing method for torsion balance composite yarn for knitting
The invention relates to a manufacturing method for torsion balance composite yarn for knitting and belongs to the technical field of knitting. The existing spinning device is used, and when the composite yarn is spun, a piece of core yarn with the twisted direction opposite to that of spindle rotation is fed. Simultaneously, a relation between spindle rotation speed and core yarn twisting degree is adjusted, and when the ratio of the twisting degree generated by spindle rotation to the twisting degree of the fed core yarn is 50%-68%, wrap yarn with the twisted direction of inner-layer core yarn opposite to that of an outer-layer fiber strip is spun to achieve torsional balance of the yarn itself. Under the premise that an additional device is not added, and production cost is reduced, remaining torsion of the yarn is eliminated, biasfilling of knitted fabric is controlled fundamentally, cutting use rate of fabric is improved, and smoothness and appearance of fabric surface are maintained.
