Description

Technical Field

[0001] The invention relates to the technical field of spandex yarn testing technology, and in particular to a device and a method for testing the adhesion of spandex yarns in a yarn cake. Background Art

[0002] In the production and application of spandex yarn, the yarn is usually wound into a yarn cake, and is generally wound on the surface of a paper tube for easy storage, transportation and subsequent processing. The adhesion of the yarn in the yarn cake is crucial to product quality and processing performance. When the yarn is wound on the paper tube to form a yarn cake, the adhesion of the yarn in the yarn cake directly affects the stability of the yarn cake during storage. If the adhesion is too low, the yarn is easy to loosen, which may cause the yarn cake to deform, become messy, etc. This not only affects the convenience of storage, but may also cause more damage during subsequent handling and transportation. At the same time, loose yarns are also more susceptible to external factors such as dust and moisture, reducing the quality of the yarn.

[0003] Referring to the Chinese patent, the patent name is: A spandex unwinding test device and its test method (patent publication number: CN117147428A), including: an unwinding mechanism, a wire guide mechanism, and a traction mechanism. The unwinding power of the present application comes from the tangential force of the first unwinding roller and the second unwinding roller. The outer circumference of the silk cake is tangent to the first unwinding roller and the second unwinding roller. During the unwinding process, the silk thread is unwound from the silk cake from the section of the unwinding roller, so that the length and tension of the silk thread between the section of the unwinding roller and the traction roller remain unchanged, thereby ensuring the stability of the unwinding test. The present application sets a pressure roller on the traction roller, and the silk thread is pulled by the traction roller and the pressure roller, which increases the static friction between the traction roller and the silk thread, improves the traction ability of the traction roller on the silk thread, and increases the holding force of the silk thread in the roller gap through the pressure roller, improves the traction stability, and thus can achieve a high traction ratio unwinding test.

[0004] Compared with the patent publication number (CN117147428A), although it is possible to test the unwinding performance of the silk thread in the silk cake and observe the adhesion of the silk thread during the unwinding process on the silk cake, there are still the following problems: the unwinding test has limited simulation of actual working conditions and cannot fully simulate the transportation and storage environment and reflect the influence of external forces. During the transportation of the silk cake, the silk cake wrapped on the paper tube will inevitably be subjected to external forces such as vibration and impact. These external forces may significantly affect the adhesion state of the silk thread.

[0005] To this end, the present invention provides a device and a method for testing the adhesion of spandex yarns in a yarn cake. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a testing device and a testing method for the adhesion of spandex yarn in a yarn cake, which solves the problem that the unwinding test in the prior art has limited simulation of actual working conditions and cannot fully simulate the transportation and storage environment and reflect the influence of external forces.

[0021] S2. After the paper tube and the silk cake are fixed, the eccentric distance of the eccentric wheel is adjusted according to the diameter of the silk cake by using the impact component.

[0024] Beneficial Effects

[0025] The present invention provides a device and method for testing the adhesion of spandex yarns in a yarn cake. Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The method for using the device for testing the adhesion of spandex yarn in a yarn cake is that the distance between the arc-shaped support plates on both sides can be controlled by an electric slide rail, thereby facilitating the arc-shaped support plates on both sides to enter the paper tube inside the yarn cake, and then the arc-shaped support plates on both sides are extended by the electric push rod, so that the arc-shaped support plates on both sides can spread outward until the arc-shaped support plates contact the inner wall of the paper tube and exert a certain pressure on the inner wall of the paper tube, so that paper tubes and yarn cakes with different diameters and lengths can be fixed, which is convenient for subsequent vibration and impact tests on the yarn cakes. At the same time, when performing the impact test, the first motor can be turned on, and the first motor drives the gear to rotate, and the gear then drives the outer gear ring and the mounting circular plate to rotate. The mounting circular plate can drive the arc-shaped support plate, the paper tube and the yarn cake to rotate, so that the impact component can impact different positions of the yarn cake, thereby improving the effect of the impact test on the yarn cake.

[0027] (2) A method for using the device for testing the adhesion of spandex yarn in a yarn cake. When performing an impact test on the yarn cake for adhesion, the yarn cakes of different diameters may be subjected to an impact test. The first rotating plate can be rotated according to the diameter of the yarn cake. The first rotating plate can drive the first screw to rotate. The first screw can then drive the first connecting slider to move in the first housing. During the movement of the first connecting slider, the eccentric wheel can be driven to move, thereby adjusting the eccentric distance of the eccentric wheel. The impact stroke and impact force of the eccentric wheel can be adjusted according to the diameter of the yarn cake to adapt to the characteristics of yarn cakes of different diameters.

[0028] (3) The method for using the device for testing the adhesion of spandex yarns in a yarn cake is to perform a vibration test on the yarns on the yarn cake by driving the rotating circular plate to rotate through the third motor, and the rotating circular plate drives the support rod to perform a circular motion. When the support rod performs a circular motion, it drives the two second sliding rods to perform a reciprocating motion in the vertical direction. Under the reciprocating motion and the elastic action of the second spring, the two second sliding rods drive the yarn cake above to vibrate. At this time, the yarns on the yarn cake can be tested for a vibration test to observe the adhesion of the yarns on the yarn cake. At the same time, by adjusting the position of the second connecting slider on the second housing The rotation radius of the support rod can be adjusted, thereby adjusting the distance of the reciprocating motion of the second sliding rod and changing the vibration amplitude of the silk cake. The vibration speed of the silk cake can be adjusted by changing the rotation speed of the third motor. Through the cooperation of the two, the influence of vibration on the adhesion of the silk thread on the silk cake can be better tested. Then the impact component and the vibration component can be turned on at the same time to test the adhesion of the silk thread under impact and vibration of the silk cake. Since the long board is long, the eccentric wheel is always in the second sliding groove on the long board when the long board moves up and down, so the eccentric wheel can impact the silk cake during the vibration of the silk cake.

[0056] Embodiment 2

[0057] See also Figure 1-11 The present invention also discloses a method for using a device for testing the adhesion of spandex yarns in a yarn cake, which specifically comprises the following steps:

[0058] S1. Adjust the distance between the two movable sliders 23 according to the length of the paper tube inside the silk cake, and then place the paper tube inside the silk cake in the middle of the two movable sliders 23. At this time, the two movable sliders 23 are brought close to each other until the arc-shaped support plates 214 on both sides enter the inner wall of the paper tube, and then the two electric push rods 26 are turned on at the same time. The output ends of the two electric push rods 26 are extended to drive the two movable blocks 216 to move respectively. During the movement, the two movable blocks 216 will drive the movable slides 218 and the arc-shaped support plates 214 on both sides to spread outward until the arc-shaped support plates 214 contact the inner wall of the paper tube and exert a certain pressure on the inner wall of the paper tube to fix the paper tube;

[0059] S2. After the paper tube and the silk cake are fixed, the first rotating plate 315 is rotated according to the diameter of the silk cake. The first rotating plate 315 drives the first screw 313 to rotate. The first screw 313 drives the first connecting slider 316 to move in the first housing 34 during the rotation. The first connecting slider 316 can drive the eccentric wheel 33 to move. The eccentric distance of the eccentric wheel 33 can be adjusted. The impact stroke and impact force of the eccentric wheel 33 can be adjusted according to the diameter of the silk cake to adapt to the characteristics of silk cakes with different diameters. Then the second motor 32 is turned on. The second motor 32 drives the eccentric wheel 33 to rotate. The eccentric wheel 33 rotates. During the movement, the long plate 35 will be squeezed, and the long plate 35 will squeeze the two first slide bars 39 together through the connecting plate 36. After the two first slide bars 39 are squeezed, they drive the rubber impact block 38 to impact the surface of the silk cake, so as to test the adhesion of the silk thread on the silk cake when it is impacted. When the silk cake is subjected to the impact test, the first motor 28 can be turned on, the first motor 28 drives the gear 29 to rotate, and the gear 29 drives the outer gear ring 211 and the mounting circular plate 210 to rotate, thereby driving the silk cake to rotate, so that the rubber impact block 38 can impact different positions of the silk cake, thereby improving the effect of the impact test on the silk cake;

[0060] S3. After the impact test is completed, a new silk cake of the same batch can be replaced to perform a vibration test on the silk thread on the silk cake. At this time, the third motor 42 can be turned on, and the third motor 42 drives the rotating circular plate 43 to rotate, and the rotating circular plate 43 drives the support rod 45 to make a circular motion. When the support rod 45 makes a circular motion, it will drive the two second sliding bars 48 to make a reciprocating motion in the vertical direction. When the two second sliding bars 48 reciprocate, they will drive the silk cake above to vibrate. At this time, the silk thread on the silk cake can be tested for a vibration test to observe the adhesion of the silk thread on the silk cake. At the same time, by adjusting the position of the second connecting slider 412 on the second housing 44, the rotation radius of the support rod 45 can be adjusted, thereby adjusting the reciprocating distance of the second sliding bar 48 and changing the vibration amplitude of the silk cake. By changing the rotation speed of the third motor 42, the vibration speed of the silk cake can be adjusted. Through the cooperation of the two, the influence of vibration on the adhesion of the silk thread on the silk cake can be better tested.

[0061] S4. After the impact test and the vibration test are completed, the adhesion of the silk thread can be tested when the silk cake is subjected to impact and vibration at the same time. At this time, the new silk cake from the same batch can be replaced again, and the impact component 3 and the vibration component 4 can be turned on at the same time to observe the adhesion of the silk thread on the silk cake when the silk cake is impacted and vibrated at the same time, so as to simulate the adhesion stability of the silk thread on the silk cake under different external force types. When the vibration component 4 is turned on, it will drive the long board 35 to shake up and down. Since the long board 35 is long, when the long board 35 shakes up and down, the eccentric wheel 33 is always in the second slide groove 312 on the long board 35, so that the eccentric wheel 33 can hit the silk cake during the vibration of the silk cake, so that the impact test and the vibration test can be carried out at the same time.
