Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a tension detection device. Background Art

[0002] Fabric is a flexible material made of warp and weft yarns through a weaving process. The arrangement, density, material and other parameters of the warp and weft yarns have an important impact on the performance of the fabric. Weaving will go through multiple process links in the entire production process, such as warping, weaving, dyeing, etc., and the tension needs to be strictly controlled in each link. Excessive weaving tension will lead to yarn breakage, fabric deformation, surface quality degradation and other problems. Too little tension will also affect the appearance and performance of the fabric. Therefore, accurate detection and control of weaving tension is crucial to ensure fabric quality and improve production efficiency.

[0003] At present, the tension of fabrics is detected by clamping the fabric with claws or two plates. After the clamp is stabilized, the tension is generated by moving the clamp to pull the fabric and the tension is calculated by the length of the clamp movement. During the clamping process, due to the different positions of force application, the fabric is prone to displacement or uneven force during the pulling and tension detection process, resulting in wrinkles, thereby affecting the accuracy of tension detection.

[0027] It also includes a detection mechanism disposed on the bearing mechanism, wherein a detection end of the detection mechanism is connected to the moving assembly and is used to pull the moving assembly to move along a first direction to perform tension detection;

[0028] By moving the locking shell 1 along the second direction, the rubber block 2 can be driven to move toward the rubber strip 3. By setting the rubber block 2 and the rubber strip 3, the fabric to be tested can be clamped. By setting multiple rubber blocks 2, the force points are dispersed. Multi-point clamping can improve the overall clamping stability and reduce the risk of local stress concentration. By using rubber, damage to the fabric can be reduced.
