Description

Technical Field

[0001] The utility model relates to the technical field of polyester filament detection, in particular to a device for detecting the tensile properties of polyester filaments. Background Art

[0002] The characteristics of polyester filaments are that they can withstand chemical substances and frequent washing, reducing the phenomenon of clothing fading and decolorization. Therefore, hotel uniforms, stone-washed blue denim clothing, sportswear or children's clothing are all made of polyester filaments. Relatively speaking, polyester filaments are tougher than rayon. When embroidering, the machine runs at high speed, and the tough polyester thread can also withstand greater tensile force, and its fire resistance is extremely high. Even if the clothing is close to the flame, it is not easy to catch fire.

[0003] The locking operation of the existing device for detecting the tensile properties of polyester filaments usually takes a long time, and when stretching the polyester filaments, the polyester filaments may slip, which easily leads to inaccurate test results. Summary of the Utility Model

The locking mechanism includes a fixed seat, a fixed column, a first locking part, a second locking part and a movable part. The first locking part is fixedly connected to the fixed seat through a fixed rod. The fixed column is fixedly installed in the middle of the fixed seat. The movable part is slidably sleeved on the fixed column and penetrates through the second locking part. An opening is formed in the first locking part, and first protruding parts are also installed on both sides of the opening on the inner wall of the first locking part. A notch is formed in the second locking part for the first protruding parts to be embedded, and second protruding parts are also installed around the outer wall of the second locking part.

[0006] By adopting the above technical solution, it is convenient to quickly lock the polyester filaments for subsequent tensile testing.

Detailed Embodiment

[0022] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0023] Referring to Figures 1-4 , a polyester filament tensile property detection device includes a stretching mechanism 1, a tensiometer 2 installed on the stretching mechanism 1, and locking mechanisms 3 provided on both sides of the stretching mechanism 1. The locking mechanism 3 includes a fixed seat 301, a fixed column 302, a first locking portion 303, a second locking portion 304, and a movable portion 305. The first locking portion 303 is fixedly connected to the fixed seat 301 through a fixed rod. The fixed column 302 is fixedly installed in the middle of the fixed seat 301. The movable portion 305 is slidably sleeved on the fixed column 302 and penetrates through the second locking portion 304. An opening 3032 is provided at the first locking portion 303. On the inner wall of the first locking portion 303, first protruding portions 3031 are further installed on both sides of the opening 3032. A notch 3042 is provided on the second locking portion 304 for the first protruding portion 3031 to be embedded. On the outer wall of the second locking portion 304, second protruding portions 3041 are also installed in a surrounding manner.

[0024] Both the first locking portion 303 and the second locking portion 304 are electromagnets. The second locking portion 304 and the first locking portion 303 as a whole are arranged in a frustum-shaped structure, and the outer wall structure of the second locking portion 304 is adapted to the inner wall structure of the first locking portion 303 so that the outer wall of the second locking portion 304 can fit against the inner wall of the first locking portion 303. A notch is provided at the fixed seat 301 to facilitate the introduction of the polyester filament. When stretching the polyester filament, the polyester filament is restricted in the notch of the fixed seat 301. The fixed column 302 has an opening 3032 on one side, and the aperture at its end is larger than the diameter of the cylindrical end of the movable portion 305 to facilitate the polyester filament to pass through the end of the first locking portion 303. The polyester filament is locked through the cooperation of the second locking portion 304 and the first locking portion 303. Three groups of second protruding portions 3041 are provided on the second locking portion 304. The second protruding portions 3041 protrude from the outer wall of the second locking portion 304, which can increase the connection tightness between the second locking portion 304 and the first locking portion 303 and increase the locking degree of the polyester filament. The notch 3042 on the second locking portion 304 corresponds to the first protruding portion 3031 on the first locking portion 303.

[0025] The fixed column 302 is composed of a cylinder and the ear plates on its side. The inner wall structure of the movable part 305 is adapted to the structure of the fixed column 302. The polyester filament can be drawn from the slot of the fixed seat 301 of a set of locking mechanisms 3 to the opening 3032, and the polyester filament can enter the inside of the first locking part 303, and then be pulled out from the first locking part 303. After that, the second locking part 304 can be pushed towards the first locking part 303 through the movable part 305, so that the second locking part 304 and the first locking part 303 are fitted together. Then, the first locking part 303 and the second locking part 304 are electrified, and the first locking part 303 and the second locking part 304 are tightly attracted together, locking the polyester filament between the first locking part 303 and the second locking part 304, that is, the fixation of one end of the polyester filament is completed. Then, the other end of the polyester filament is drawn to another set of locking mechanisms 3, and the other end of the polyester filament is locked in the same way as above;

[0026] It should be noted that before the two ends of the polyester filament are tightly locked by the first locking part 303 and the second locking part 304, the polyester filament needs to be straightened and have tension;

[0027] After the placement of the two ends of the polyester filament is completed, the polyester filament can be hung on the hook of the tensile tester 2, and the stretching mechanism 1 is driven to pull the polyester filament for tensile testing. The two sets of locking mechanisms 3 are fixedly connected through the connecting rod 4. The two sets of locking mechanisms 3 are fixed on the base, and the two sets of locking mechanisms 3 are stably connected again through the connecting rod 4.

[0028] 1 includes a motor, a slide rail, a slide seat and a lead screw. The driving motor can drive the slide seat to slide along the slide rail through the lead screw. When the slide seat slides, it can synchronously drive 2 to move, and the polyester filament is subjected to tensile testing through 2.

[0029] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
