Description
Technical Field
[0001] The utility model relates to the technical field of fabric testing equipment, in particular to a yarn wear resistance tester with strong protectiveness. Background Art
[0002] In the existing textile industry, after purchasing or self-preparing yarn, the yarn is generally tested first. Yarn testing is an indispensable and important procedure in the process of cloth production in textile factories to confirm whether the yarn has defects and whether the quality meets the requirements. Yarn wear tester is a kind of testing instrument. The existing Shaxian wear tester needs to use a large weight when testing some yarns with better strength. When the yarn is worn off, the weight falls and may damage the mounting platform and frequency sensor of the tester, which needs to be improved urgently. Utility Model Content
[0003] In order to solve the deficiencies of the above-mentioned technology, the utility model provides a yarn wear tester with strong protection. The yarn wear tester comprises a tester body, a weight and an operating table. The tester body is arranged on the operating table. The tester body is provided with a plurality of mounting wheels, a weight mounting table and a number sensor. The operating table is provided with a protection device. The protection device comprises a buffer base, a plurality of sliding rods, a plurality of buffer compression springs and a sensor protection mechanism. The buffer base is fixedly arranged on the operating table at a position below the number sensor. One end of the plurality of sliding rods is fixedly connected to the bottom of the weight mounting table. The buffer base is provided with a plurality of buffer slots matching the sliding rods. The plurality of sliding rods are respectively arranged in the plurality of buffer slots. The plurality of buffer compression springs are respectively sleeved on the plurality of sliding rods and the two ends are respectively in contact with the buffer base and the weight mounting table. The weight mounting table is movably connected to the buffer base through the cooperation of the sliding rods and the buffer slots, and the sensor protection mechanism is detachably connected to the weight.
[0004] By adopting the above technical scheme, a protection device including a buffer base, a plurality of sliding rods, a plurality of buffer compression springs and a sensor protection mechanism is arranged on the operating table, so that the weight mounting platform is movably connected with the buffer base through the cooperation of the sliding rod and the buffer slot hole. When a heavy weight falls due to the yarn being broken, the weight first falls on the weight mounting platform, and the weight mounting platform unloads the force in the buffer slot hole through the sliding rod and the buffer compression spring to avoid damage to the weight mounting platform. Then, the sensor is protected by the sensor protection mechanism when the weight mounting platform descends, thereby ensuring the safety of the experiment.
[0005] The utility model is further configured as follows: a plurality of rubber speed reduction blocks are arranged on the peripheral surface of the buffer slot hole close to the bottom.
[0006] By adopting the above technical solution, since a plurality of rubber deceleration blocks are arranged on the peripheral surface of the buffer slot near the bottom, the falling of the weight mounting platform can be further buffered and decelerated and shock-absorbed.
[0007] Further configuration of the utility model: the sensor protection mechanism includes a mounting sleeve, an L-shaped extension rod and a sensing metal sheet, the mounting sleeve is fixedly arranged at one end of the L-shaped extension rod, and the sensing metal sheet is connected to the L-shaped extension rod through a torsion spring and rotates together.
[0008] By adopting the above technical scheme, since the sensor protection mechanism includes a mounting sleeve, an L-shaped extension rod and a sensing metal sheet, the mounting sleeve is fixedly arranged at one end of the L-shaped extension rod, and the sensing metal sheet is connected to the L-shaped extension rod through a torsion spring and rotates together. By setting the sensing metal sheet on the L-shaped extension rod, the weight can avoid the sensor as a whole when the weight mounting platform falls, and only a part of the sensing metal sheet contacts the sensor. The sensing metal sheet is then set on the L-shaped extension rod through the torsion spring, so that the sensing metal sheet can gently slide over the surface of the sensor to avoid serious collision with the sensor. At the same time, normal counting of the sensor when the yarn is not broken and protection of the sensor when the yarn is broken are guaranteed.
[0009] A further configuration of the utility model is that a rubber protective pad is also provided at a position on the buffer base corresponding to the L-shaped extension rod.
[0010] By adopting the above technical solution, since a rubber protective pad is further provided at a position on the buffer base corresponding to the L-shaped extension rod, the L-shaped extension rod can be further protected. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] By arranging a protection device including a buffer base, a plurality of slide bars, a plurality of buffer compression springs and a sensor protection mechanism on the operating table, the weight mounting platform is movably connected with the buffer base through the cooperation of the slide bars and the buffer slot holes. When a heavy weight falls due to the yarn being broken, the weight first falls on the weight mounting platform, and the weight mounting platform unloads the force in the buffer slot holes through the slide bars and the buffer compression springs to avoid damage to the weight mounting platform. Then, the sensor protection mechanism is used to protect the sensor when the weight mounting platform descends, thereby ensuring the safety of the experiment.
[0017] A plurality of rubber speed reduction blocks 13 are arranged on the peripheral surface of the buffer slot near the bottom.

By setting the sensing metal sheet on the L-shaped extension rod, the weight can avoid the sensor as a whole when the weight mounting platform falls, and only a part of the sensing metal sheet contacts the sensor. The sensing metal sheet is then set on the L-shaped extension rod through the torsion spring, so that the sensing metal sheet can gently slide over the surface of the sensor to avoid serious collision with the sensor. At the same time, normal counting of the sensor when the yarn is not broken and protection of the sensor when the yarn is broken are guaranteed.
