Description

Technical Field

[0001] The invention relates to the technical field of line tension testing, in particular to a textile yarn tension testing device. Background Art

[0002] Yarn, as the basic component of textiles, is a long and thin material processed from various textile fibers. It has different fineness and strength and is widely used in weaving fabrics, making ropes, sewing threads, knitwear, embroidery and other fields. There are many types of yarns, including short fiber yarns, continuous filament yarns and other forms. They are the indispensable basic materials for various textiles. In practical applications, yarn and wool are not only used to weave warm clothing such as sweaters, wool pants, and wool vests, but are also often used to make scarves, hats, gloves and other clothing accessories. In addition to providing the necessary warmth, they also have a good decorative effect, adding color to people's daily lives.

[0003] However, before the yarn is put into use, tension testing is an important step in ensuring product quality. Tension testing can evaluate the strength and durability of the yarn, which is crucial to ensuring the quality and performance of textiles. At present, existing tension testing devices have some limitations. They are usually unable to perform tension testing at the same time during the yarn winding process. This requires completing the tension test before winding the yarn. Such a process undoubtedly increases the workload and reduces production efficiency. In addition, when measuring tension, existing tension testing devices often find it difficult to accurately measure the ultimate tension value of the yarn, which affects the accuracy and reliability of the measurement results and limits their scope of application in actual production.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 2. When the motor is running, the rotating rod not only drives the winding disk to rotate, but also realizes the reciprocating sliding of the winding disk through the sliding of the annular groove, the ball, the movable rod and the limit strip in the limit groove. This design enables the winding disk to adjust its position while rotating, ensuring uniform winding of the yarn and improving the winding quality.

[0024] 3. The operator holds handle 1 and handle 2 and presses them downward. Handle 2 is fixed by positioning rod 2 inserted into the deep positioning hole. Handle 1 drives adjusting roller 1 to slide along the guide groove and squeezes the support block until it fits with the bottom of the guide groove. Positioning rod 1 and spring 2 cooperate to fix adjusting roller 1. In this way, adjusting roller 1 fits with fixed roller 1 to increase the yarn tension, which is convenient for measuring the ultimate tension. If adjusting roller 2 needs to be adjusted, first push handle 1 to insert the pin into the slot of positioning rod 2, and then press the handle. Positioning rod 2 will slide and adjust, and finally fit with the deep positioning hole on the lower side, so that fixed roller 2 fits with adjusting roller 2. This process improves the adjustment flexibility and practicality of the equipment. The operator can perform relative operations according to different situations and different yarns, so as to measure the ultimate tension of different yarns. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1;

[0040] See also Figure 1 to Figure 6 The present invention provides a technical solution: a textile yarn tension testing device, comprising a main frame 1, a dynamometer 2 adapted to be installed inside the top of the main frame 1, and a fixed roller 1 3 and a fixed roller 2 4 rotatably connected inside the main frame 1, and also comprising:

[0041] A motor 5 is adapted to be installed on the outside of the back side of the main frame 1 , a winding reel 6 is arranged on the outside of the output end of the motor 5 , and an adjusting roller 1 7 and an adjusting roller 2 8 are arranged inside the main frame 1 .

[0042] Preferably, a bolt 21 is provided on the outer side of the dynamometer 2 , and a hook 22 is provided on the bottom end of the dynamometer 2 , and the dynamometer 2 is installed on the top of the main frame 1 through the bolt 21 .

[0043] Preferably, the output end of the motor 5 is fixedly connected to a rotating rod 51 , the outer side of the rotating rod 51 is fixedly connected to a disc 52 , one end of the disc 52 is fixedly connected to a long rod 53 , and an annular groove 54 is provided on the outer side of the rotating rod 51 .

[0044] When the yarn needs to be wound up, Figure 4 The yarn passes through the fixed roller 1 3 , the adjusting roller 1 7 , the hook 22 , the fixed roller 2 4 and the adjusting roller 2 8 in sequence and is fixed on the outer side of the winding drum 6 .

[0045] Then the operator starts the motor 5. After the motor 5 is running, it will drive the rotating rod 51 at the output end of the motor 5 to rotate. The rotating rod 51 will drive the disc 52 fixed on the outside thereof to rotate. The long rod 53 on the outside of the disc 52 is inserted into the sliding cavity 61 on the outside of the winding disk 6, which will drive the winding disk 6 to rotate, thereby completing the winding of the yarn.

[0046] At the same time, when the winding disk 6 rotates to wind up the yarn, the yarn will be tightened, thereby applying pressure to the hook 22 and finally transmitting it to the dynamometer 2, and the tension of the yarn can be measured by the dynamometer 2. Since the yarn is continuously wound up, the tension of the wound yarn can be fully measured, and the tension of the entire yarn can be accurately grasped.

[0047] Compared with the transmission method that requires the yarn to be tension tested before winding, this device can realize the winding and measurement work in one piece, effectively improving the overall efficiency.

[0048] In summary, the yarn is fixed on the winding disk 6 after a series of windings. After starting the motor 5, the rotating rod 51 and the disc 52 drive the winding disk 6 to rotate, thereby winding the yarn. At the same time, the tension generated by winding is transmitted to the dynamometer 2 through the hook 22 to measure the yarn tension. This design allows winding and tension measurement to be performed simultaneously, thereby improving work efficiency.

[0049] Embodiment 2 improves the specific process based on embodiment 1. For specific methods, please refer to Figure 6 and Figure 7 ;

[0050] It should be noted that a sliding cavity 61 is provided at one end of the winding disk 6, a movable rod 62 is rotatably connected to one end of the winding disk 6, a ball 63 is fixedly connected to the inner wall of the movable rod 62, and a limit strip 64 is fixedly connected to the outer side of the movable rod 63;

[0051] Among them, the movable rod 63 is arranged inside the round hole 12, the limit bar 64 is located inside the limit groove 13, the winding disk 6 is sleeved on the outside of the rotating rod 51, the long rod 53 is slidably connected inside the sliding cavity 61, and the ball 62 is located inside the annular groove 54.

[0052] When the motor 5 drives the winding drum 6 to rotate through the rotating rod 51, the cooperation between the annular groove 54 and the ball 63, and the design that the limit bar 64 on the outside of the movable rod 62 slides inside the limit groove 13, the rotating rotating rod 51 will continuously drive the movable rod 62 to slide back and forth inside the circular hole 12, and the rotating rod 51 will drive the winding drum 6 to slide back and forth while rotating.

[0053] The design of the reel 6 sliding back and forth and rotating can not only ensure that the position of the reel 6 is constantly adjusted during the reeling process, but also ensure that the yarn can be evenly wound around the outside of the reel 6, thereby improving the quality of reeling. While the reel 6 reciprocates and adjusts its position, it will change the pulling force of the yarn on the hook 22, thereby realizing the measurement of the threshold value of the yarn tension, prompting personnel to understand the yarn more accurately, and further improving the practicality of the equipment.

[0054] In summary, when the motor 5 is running, the rotating rod 51 not only drives the winding disc 6 to rotate, but also realizes the reciprocating sliding of the winding disc 6 through the sliding of the annular groove 54, the ball 63, the movable rod 62 and the limit strip 64 in the limit groove 13. This design enables the winding disc to adjust its position while rotating, ensuring uniform winding of the yarn and improving the winding quality. At the same time, the reciprocating sliding of the winding disc 6 changes the tension on the hook 22, allowing the tension threshold of the yarn to be measured, thereby more accurately grasping the yarn state and enhancing the practicality of the device.

[0055] Embodiment 3 is further described in detail based on the above embodiment 2. Figure 8 to Figure 12 , the specific method is as follows:

[0056] Further, a guide groove 11 is provided on the outer side of the main frame 1, a round hole 12 is provided on the outer side of the main frame 1, a limiting groove 13 is provided on the inner wall of the round hole 12, a shallow positioning hole 14 is provided on the outer side of the main frame 1, a deep positioning hole 15 is provided on the outer side of the main frame 1, and a slide rod 16 is slidably connected to the bottom end of the guide groove 11;

[0057] There are two groups of deep positioning holes 15 and three groups of shallow positioning holes 14 . Both ends of the adjusting roller 1 7 and the adjusting roller 2 8 are located inside the guide groove 11 and slide along the inside of the guide groove 11 .

[0058] Furthermore, a support block 161 is fixedly connected to the top end of the slide bar 16, and a spring 162 is fixedly connected to the bottom end of the slide bar 16;

[0059] The support block 161 slides inside the guide groove 11 , and the other end of the spring 162 is fixedly connected to the inside of the main frame 1 .

[0060] It should be noted that the outer side of the adjusting roller 7 is slidably connected to a connecting rod 71 , and the outer side of the connecting rod 71 is fixedly connected to a handle 72 .

[0061] Furthermore, the interior of the connecting rod 71 is slidably connected to a positioning rod 711, the outer side of the positioning rod 711 is sleeved with a spring 712, and the outer side of the connecting rod 71 is fixedly connected to a latch 713;

[0062] Among them, one end of the second spring 712 is fixedly connected to the positioning rod 1 711, and the other end is fixedly connected to the inner wall of the connecting rod 1 71, and the positioning rod 1 711 is clamped with the shallow positioning hole 14.

[0063] Furthermore, a second connecting rod 81 is fixedly connected to the outer side of the second adjusting roller 8 , and a second handle 82 is fixedly connected to the outer side of the second connecting rod 81 .

[0064] Preferably, the second connecting rod 81 is slidably connected to the second positioning rod 811, the outer side of the second positioning rod 811 is sleeved with a third spring 812, and the interior of the second positioning rod 811 is provided with a slot 813;

[0065] Among them, one end of spring three 812 is fixedly connected to positioning rod two 811, and the other end is fixedly connected to the inner wall of connecting rod two 81, one side of the slot 813 is set as an inclined surface, positioning rod two 811 is clamped with the deep positioning hole 15, the overall length of positioning rod two 811 is greater than the overall length of positioning rod one 711, and the pin 713 cooperates with the slot 813 to adjust the position of positioning rod two 811.

[0066] The operator holds the first handle 72 and the second handle 82 respectively and presses them downwards. Since the second handle 82 is completely inserted into the deep positioning hole 15 through the second positioning rod 811, the second handle 82 cannot be driven to move downwards.

[0067] At this time, the grip 1 72 will drive the adjusting roller 1 7 to slide along the inside of the guide groove 11 under the action of pressure, and squeeze the support block 161 until the support block 161 is completely in contact with the bottom of the guide groove 11. During the downward pressing process, the positioning rod 1 711 will cooperate with the spring 2 712 to slide out from the upper shallow positioning hole 14, and after the support block 161 is completely in contact with the bottom of the guide groove 11, the positioning rod 1 711 is driven by the elasticity of the spring 2 712 to be clamped in the shallow positioning hole 14 directly below the upper shallow positioning hole 14, thereby fixing the adjusting roller 1 7.

[0068] At this time, the adjusting roller 7 is in contact with the fixed roller 3 to squeeze the wound yarn and rub the yarn. As the winding disk 6 continues to rotate, the tension of the yarn increases, and the ultimate tension of the yarn can be measured, thereby increasing the measurement range of the device and further improving the practicability of the device.

[0069] When it is necessary to adjust the adjusting roller 8, push the handle 72 before pressing it down, so that the pin 713 at one end of the connecting rod 71 is inserted into the slot 813 of the positioning rod 811, and the positioning rod 811 is driven to slide and adjust inside the deep positioning hole 15 due to the design of the inclined surface of the slot 813. Then, press the handle 72 and the handle 82 at the same time, so that the positioning rod 811 can be forced to leave the deep positioning hole 15 on the upper side and engage with the deep positioning hole 15 on the lower side. At the same time, the positioning rod 711 is engaged with the shallow positioning hole 14 on the right side of the deep positioning hole 15 on the lower side, so that the adjusting roller 7 is finally fitted with the fixed roller 3, and the fixed roller 4 is fitted with the adjusting roller 8.

[0070] Therefore, the operator can perform relative operations according to different situations and different yarns, so as to measure the ultimate tension of different yarns and further improve the practicality of the equipment.

[0071] In summary, the operator holds the handle 1 72 and the handle 2 82 and presses them downward, and the handle 2 82 is fixed by the positioning rod 2 811 into the deep positioning hole 15. The handle 1 72 drives the adjusting roller 1 7 to slide along the guide groove 11, and squeezes the support block 161 until it fits with the bottom end of the guide groove, and the positioning rod 1 711 and the spring 2 712 cooperate to fix the adjusting roller 1 7. In this way, the adjusting roller 1 7 fits with the fixed roller 1 3, increasing the yarn tension, which is convenient for measuring the limit tension.

[0072] If the adjusting roller 2 8 needs to be adjusted, first push the handle 1 72 to insert the pin 713 into the slot 813 of the positioning rod 2 811, then press the handle, the positioning rod 2 811 will slide and adjust, and finally engage with the lower deep positioning hole 15, so that the fixed roller 2 4 and the adjusting roller 2 8 are fitted. This process improves the adjustment flexibility and practicality of the equipment, and the operator can perform relative operations according to different situations and different yarns, so as to measure the ultimate tension of different yarns.

[0073] Embodiment 4: This embodiment is based on the overall operation mode of the above embodiment, which can be referred to Figures 1 to 12 , the specific method is as follows:

[0074] In the yarn winding operation, the yarn passes through the fixed roller 1 3, the adjusting roller 1 7, the hook 22, the fixed roller 2 4 and the adjusting roller 2 8 in sequence, and finally winds on the winding disk 6. The operator starts the motor 5, and its rotating rod 51 drives the disc 52 and the long rod 53 to rotate the winding disk 6 and complete the winding. In this process, the tension of the yarn is transmitted to the dynamometer 2 through the hook 22 for real-time monitoring.

[0075] When the motor 5 is working, the rotating rod 51 is linked to the winding disk 6 to rotate and reciprocate, and this action is achieved by the sliding of the annular groove 54, the ball 63, the movable rod 62 and the limit bar 64 in the limit groove 13. Such a design helps to evenly wind the yarn, improve the winding quality, and measure the tension limit of the yarn by changing the tension on the hook 22.

[0076] The operator squeezes and presses the handle 1 72 and the handle 2 82, wherein the handle 2 82 is fixed in the deep positioning hole 15 by the positioning rod 2 811. The movement of the handle 1 72 pushes the adjusting roller 1 7 to slide along the guide groove 11, squeezes the support block 161, and is fixed in position by the positioning rod 1 711 and the spring 2 712, thereby increasing the friction and tension on the yarn. If the adjusting roller 2 8 needs to be adjusted, the operator pushes the handle 1 72 to insert the pin 713 into the slot 813 of the positioning rod 2 811, and then presses the handle, so that the positioning rod 2 811 slides to the lower deep positioning hole 15 and engages, thereby achieving the fit between the fixed roller 2 4 and the adjusting roller 2 8. This adjustment mechanism improves the adaptability of the device to different types of yarns and the accuracy of tension measurement.

[0077] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
