Description

A cotton spinning tensile testing device Technical Field

[0001] This utility model relates to the field of cotton spinning tensile strength technology, specifically a cotton spinning tensile strength testing device. Background Technology

[0002] Cotton yarn is yarn made from cotton fibers through spinning processes. With the improvement of living standards, people have more and more demand for cotton textiles and higher requirements, including requirements for softness and elasticity. Therefore, after production, it is necessary to conduct tensile tests on the produced cotton yarn to check whether the cotton yarn meets the requirements. At present, tensile tests are generally conducted by pulling to test the maximum tensile force that cotton yarn can withstand.

[0003] Chinese patent CN221925914U discloses a cotton yarn tensile testing device, including an external housing with a clamping assembly inside. The clamping assembly includes a first sliding rod and a second sliding rod. A fixed base is installed on the outer wall of the first sliding rod, and a first motor is installed inside the fixed base. A first rotating roller is installed at the output end of the first motor, and a fixed collar is rotatably installed at the other end of the first rotating roller. The fixed collar is installed on the outer wall of the second sliding rod. A second rotating roller is also provided between the first and second sliding rods. Both the first and second rotating rollers have placement slots, and rubber pads are placed at the top and bottom of the placement slots. The cotton yarn to be tested for tensile strength is fixed by the two rotating rollers. After the cotton yarn is placed in the placement slot, the motor drives the rotating rollers to rotate about two revolutions to automatically fix both ends of the cotton yarn. The rubber pads increase the friction and thus increase the firmness of the fixation.

[0004] The aforementioned patent has some shortcomings: it only uses the extension distance of the electric push rod to pull cotton yarn, but when encountering cotton yarn with high elasticity during use, the extension length of the electric push rod alone cannot effectively detect the tension of the cotton yarn. Summary of the Invention

[0005] The purpose of this invention is to provide a cotton spinning tensile testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cotton spinning tensile strength testing device, comprising a machine base, with a first mounting plate and a second mounting plate symmetrically mounted at both ends of the top of the machine base, a first roller mounted between the two first mounting plates, and a first fixing component provided at the bottom of the first roller, a second roller rotatably mounted between the two second mounting plates, a unidirectional rotation component provided at one end of the second roller, and a reading component provided at the other end of the second roller, a rectangular groove opened on the second roller, and a second fixing component provided in the rectangular groove, a rocker arm rotatably mounted on the second mounting plate, and the rocker arm being used to drive the second roller to rotate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This cotton spinning tensile testing equipment is equipped with a crank handle and a second roller. When it is necessary to test the tensile strength of cotton spinning, one end of the cotton spinning is fixed on the first roller and the other end is fixed on the second roller. Then, the worker holds the crank handle to drive the second roller to rotate. The rotating second roller can wrap the cotton spinning around its outer side, thereby allowing unlimited testing of the extended part of the stretched cotton spinning, improving practicality and solving the drawbacks of the above-mentioned patents.

[0017] In addition, the cotton spinning tensile strength testing equipment is also equipped with a ratchet, a pawl, and a spring. During the rotation of the second roller, in order to prevent the second roller from being pulled back by the cotton spinning yarn, the ratchet, the rectangular bar, and the spring work together to ensure that the ratchet can only rotate in one direction, thereby preventing the second roller from rotating back.

[0028] Please refer to Figures 1-4. One embodiment of this utility model is provided: a cotton spinning tensile strength testing device, including a machine base 1. A first mounting plate 2 and a second mounting plate 6 are symmetrically installed at both ends of the top of the machine base 1. A first roller 3 is installed between the two first mounting plates 2, and a first fixing component is provided at the bottom of the first roller 3. A second roller 7 is rotatably installed between the two second mounting plates 6. A unidirectional rotation component is provided at one end of the second roller 7, and a reading component is provided at the other end of the second roller 7. A rectangular groove 9 is opened on the second roller 7, and a second fixing component is provided in the rectangular groove 9. A rocker handle 8 is rotatably installed on the second mounting plate 6, and the rocker handle 8 is used to drive the second roller 7 to rotate.

[0029] Specifically, when it is necessary to perform tension testing on cotton yarn, one end of the cotton yarn is fixed on the first roller 3 and the other end is fixed on the second roller 7. Then, the worker holds the crank handle 8 to drive the second roller 7 to rotate. The rotating second roller 7 can wrap the cotton yarn around its outside, thus allowing unlimited testing of the extended part of the stretched cotton yarn, improving practicality and solving the drawbacks of the above-mentioned patent.

[0030] Furthermore, the first fixed component includes an electric push rod 4 vertically mounted on the top of the machine base 1, and an arc plate 5 mounted on the output end of the electric push rod 4, with the top of the arc plate 5 engaging with the bottom of the first roller 3;

[0031] Specifically, by winding one end of the cotton yarn around the first roller 3, and then starting the electric push rod 4 to move the arc plate 5 upward, the cotton yarn can be fixed on the first roller 3 through the arc plate 5.

[0032] Furthermore, the unidirectional rotation assembly includes a ratchet 10, a pawl 11, and a spring 13. The ratchet 10 is installed at the end of the second roller 7, the pawl 11 is rotatably installed on the side wall of the second mounting plate 6, and the spring 13 is installed on the top of the pawl 11. A rectangular bar 12 is installed on the top of the spring 13, and the rectangular bar 12 is fixedly installed to the outside of the second mounting plate 6.

[0033] Specifically, during the rotation of the second roller 7, in order to prevent the second roller 7 from being pulled back by the cotton yarn, the ratchet 10 can only rotate in one direction through the cooperation between the pawl 11, the rectangular bar 12 and the spring 13, thereby preventing the second roller 7 from rotating back.

[0034] Furthermore, the reading component includes a dial 17 and a pointer 18. The dial 17 is mounted on the outside of the second mounting plate 6, and the pointer 18 is mounted on the crank 8. The pointer 18 and the dial 17 cooperate with each other. The dial 17 is located on the outside of the two second mounting plates 6.

[0035] Specifically, as the crank 8 drives the pointer 18 to rotate, the pointer 18 points to the scale on the dial 17, and the number of revolutions and degrees of the second roller 7 can be read.

[0036] Furthermore, the second fixing component includes a clamping plate 14, a bolt 15, and a receiving groove 16. The clamping plate 14 is movably disposed in the rectangular groove 9. The receiving groove 16 is opened on the outer side of the second roller 7, and the bolt 15 is threaded through the receiving groove 16. The through end of the bolt 15 is rotatably installed on the outer side of the clamping plate 14.

[0037] Specifically, the other end of the cotton yarn is placed into the rectangular groove 9, and then the bolt 15 is rotated by a tool. The bolt 15 pushes the clamping plate 14 to clamp the cotton yarn. The opening of the receiving groove 16 can accommodate the bolt 15, ensuring that there are no protruding parts on the outside of the second roller 7.

[0038] Working principle: When it is necessary to perform tension testing on cotton yarn, one end of the cotton yarn is fixed on the first roller 3 and the other end is fixed on the second roller 7. Then, the worker holds the crank handle 8 to drive the second roller 7 to rotate. The rotating second roller 7 can wrap the cotton yarn around its outside, thus allowing unlimited testing of the extended part of the pulled cotton yarn. In order to prevent the second roller 7 from rotating back due to the pull of the cotton yarn, the ratchet 10 can only rotate in one direction through the cooperation between the pawl 11, the rectangular bar 12 and the spring 13, thereby preventing the second roller 7 from rotating back. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
