Description

Technical Field

[0001] The utility model relates to a polyester filament elasticity testing device, belonging to the textile field. Background Technique

[0002] Polyester filaments have good resilience and toughness. Elasticity and elastic recovery performance are important indicators for measuring the quality of polyester filaments. When testing the elasticity of polyester filaments, the polyester filaments are lapped in the pulleys at the top of the vertical plate with scale lines, and then one end of the polyester filaments is restricted on the vertical plate, and the other end of the polyester filaments is tied with weights. Under the pulling of the weights, the polyester filaments are stretched, and the length value of the polyester filaments pulled is measured through the scale lines, and the elastic force value of the polyester filaments is calculated by a fixed formula. In this way, during the testing process, the polyester filaments may be broken. After the polyester filaments are broken, the landing points of the weights are not controlled and will fall randomly, so the probability of damage to the weights is relatively high. Therefore, it is necessary to design a polyester filament elasticity testing device that restricts the falling trajectory of the weights in the case of broken filaments. Content of the Utility Model

Detailed implementation manners

[0022] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with the detailed implementation manners.

[0023] Please refer to Figure 1 , Figure 2 and Figure 5 , the present utility model provides a technical solution: an elastic testing device for polyester filaments, including a base 1. A plurality of storage grooves 14 are evenly formed on one side surface of the base 1. A counterweight bar 12 is inserted into the storage groove 14. By inserting the counterweight bar 12 into the storage groove 14 of the base 1, the weight of the base 1 is increased, so that the center of gravity of the structure formed by the base 1 and the vertical plate 7 is lowered, and the stability of the structure is improved.

[0024] Refer to Figures 1 - 3 , a vertical plate 7 is installed on one side of the upper surface of the base 1. Scale lines 8 arranged from top to bottom are processed on one side surface of the vertical plate 7. A pulley 9 for supporting the polyester filament 6 is rotatably installed at the upper end of the vertical plate 7. Among them, a notch 17 is processed at the middle position of the upper end of the vertical plate 7. Shaft grooves 16 are processed at the upper positions of two parallel side surfaces in the notch 17. Shaft heads are connected and fixed at the middle positions of two parallel side surfaces of the pulley 9, so that the shaft heads are slidably installed in the shaft grooves 16 to complete the assembly of the pulley 9 and the vertical plate 7.

[0025] Refer to Figures 1 - 3 , the polyester filament 6 is lapped inside the pulley 9. A stud 13 for restricting the position of one end of the polyester filament 6 is installed at the upper position of the side of the vertical plate 7 facing away from the scale line 8. Among them, a vertically arranged threading hole 15 is formed on the circumferential side surface of the stud 13, and a fillet is processed at the edge of the threading hole 15, so that one end of the polyester filament 6 passes through the threading hole 15, which is convenient for tying the polyester filament 6 to the stud 13. A weight 4 is tied to the end of the polyester filament 6 away from the stud 13. A hanging ring is connected and fixed at the middle position of the upper surface of the weight 4. The end of the polyester filament 6 away from the stud 13 is tied to the hanging ring, and the hanging ring is convenient for the connection between the polyester filament 6 and the weight 4.

[0026] Refer toFigures 1 - 4 On the lower part of one side of the vertical plate 7, a vertical groove 5 is machined. After the weight 4 is connected to the polyester filament 6, the weight 4 is located within the vertical groove 5, which is conducive to making the polyester filament 6 close to the scale line 8 and facilitating the acquisition of the stretched length of the polyester filament 6. A ring 3 is sleeved on the weight 4, and a positioning screw 2 for restricting the relative position between the ring 3 and the weight 4 is threadedly connected to the outer surface of the ring 3. A threaded sleeve 19 is installed on the outer surface of the ring 3, and circular holes are formed in the area of the circumferential side of the ring 3 covered by the threaded sleeve 19, enabling the positioning screw 2 to be threadedly connected within the threaded sleeve 19 to complete the stable assembly of the positioning screw 2 and the ring 3. The inner diameter of the circular hole is larger than the outer diameter of the positioning screw 2, facilitating one end of the positioning screw 2 to extend into the ring 3 to contact the weight 4. Two sliders 18 are fixedly connected to the outer surface of the ring 3, and vertically arranged sliding grooves 10 are formed on two parallel sides of the vertical groove 5. The two sliders 18 are respectively slidably installed within the two sliding grooves 10. The ring 3 is sleeved on the weight 4, and then the relative position between the ring 3 and the weight 4 is restricted by the positioning screw 2. When the polyester filament 6 breaks during the test, the weight 4 drives the ring 3 to move downward, and the ring 3 drives the sliders 18 to slide along the sliding grooves 10. The cooperation between the sliders 18 and the sliding grooves 10 restricts the falling trajectory of the weight 4 and prevents the weight 4 from falling randomly and being damaged.

[0027] Refer to Figure 1 、 Figure 2 and Figure 5 , a sponge pad 11 is provided directly below the weight 4. The area of the upper surface of the base 1 directly below the weight 4 is recessed downward to form a groove 20, and the sponge pad 11 is inserted into the groove 20. When the weight 4 drops, the weight 4 falls onto the sponge pad 11, achieving the purpose of buffer protection, avoiding hard contact between the weight 4 and the base 1, and improving the protection effect on the weight 4.
