Description

Technical Field

[0001] This invention relates to the field of textile testing technology, specifically to a fully automated integrated device and method for testing the strength of single yarns. Background Technology

[0002] Single yarn strength testing is a core testing item for measuring yarn quality in the textile industry. It is mainly used to determine parameters such as the strength (such as breaking load and breaking strength) and elongation of a single yarn during the tensile breaking process. It is a key technology for evaluating the mechanical properties of yarn, guiding the optimization of textile processes and quality control.

[0003] Traditional single yarn strength testing equipment suffers from significant efficiency drawbacks due to its reliance on manual operation throughout the entire process: the manual sample loading process is cumbersome and the single testing cycle is long, which cannot meet the rapid testing needs of large-scale production. Furthermore, subjective factors such as differences in operator technique and fatigue lead to poor repeatability and insufficient reliability of test data. In addition, when testing different batches or types of yarn, frequent machine stops are required to change the yarn spool, which is time-consuming and seriously affects the efficiency of continuous testing. Mechanical errors are also easily introduced during the replacement process, further reducing the accuracy of the test results. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic integrated device for testing the strength of single yarns. Through the design of differential transmission, the time-consuming problem of manual component replacement is completely eliminated, resulting in a significant improvement in testing efficiency. This meets the needs of large-scale production and continuous testing of the equipment itself, thereby effectively solving the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic integrated device for single yarn strength testing, comprising: a mounting plate, a testing mechanism, and a yarn changing mechanism, wherein the testing mechanism and the yarn changing mechanism are respectively mounted on one side of the outer wall of the mounting plate;

The linkage gear meshes between the outer rotating disk and the inner gear to generate differential rotation. A fixed frame is fixedly installed on one side of the outer wall of the linkage gear. The fixed frame changes its position and angle as the outer rotating disk rotates and the differential rotation is generated.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, the differential transmission design of the equipment can be realized through the cooperation of the outer rotating disk, internal gear, and linkage gear in the drum changing mechanism. With the cooperation of the fixed frame and other components, the drum can be automatically picked up, the angle adjusted and aligned. The time for a single drum change is reduced to the second level, completely eliminating the time-consuming problem of manual part changing.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In the testing of single yarn strength, traditional testing devices have many problems in practical applications and are difficult to meet the testing requirements.

[0032] In textile production, traditional single yarn strength testing equipment relies entirely on manual operation, resulting in significant inefficiencies and data inaccuracies. The manual sample loading process is cumbersome, with each test cycle lasting several minutes. This makes it difficult to meet the rapid testing demands of large-scale production. Furthermore, manual operation is susceptible to individual variations in technique; subtle differences in the force applied and the sequence of steps by different personnel can lead to fluctuations in test data. Fatigue from prolonged work further exacerbates the problem of poor data repeatability, resulting in inaccurate test data. Moreover, traditional equipment requires frequent shutdowns to replace yarn spools when testing different batches or types of yarn. The compatibility of spool specifications and materials directly affects the testing results. Each replacement requires disassembly, installation, and calibration, which is time-consuming and severely disrupts the continuous testing process. Even slight errors during replacement, such as spool eccentricity or uneven tension, can introduce mechanical errors, causing test data to deviate from the true value, reducing the accuracy of the test results and posing a threat to production quality control.

[0033] This invention was made to solve the problems of this prior art, through embodiments of the invention, referring to Figure 1 , Figure 2 and Figure 3 As shown: A fully automatic single yarn strength testing integrated device includes: a mounting plate 1, a testing mechanism 2 and a bobbin changing mechanism 3, wherein the testing mechanism 2 and the bobbin changing mechanism 3 are respectively installed on one side of the outer wall of the mounting plate 1;

[0034] Specifically, the cylinder changing mechanism 3 includes an outer rotating disk 33, an inner gear 332, an inner rotating disk 4, a linkage gear 34, and a fixed frame 35. The linkage gear 34 meshes and drives between the outer rotating disk 33 and the inner gear 332 to generate differential rotation. A fixed frame 35 is fixedly installed on one side of the outer wall of the linkage gear 34. The fixed frame 35 rotates with the outer rotating disk 33 and generates differential rotation, which is used to change the position and angle of the fixed frame 35 itself.

[0035] In some embodiments, according to Figure 4 as well as Figure 8As shown, the outer rotating disk 33 has an internal transmission gear 331 inside, and the linkage gear 34 meshes with the internal transmission gear 331. When the external motor drives the outer rotating disk 33 to rotate as a whole, it can rotate the linkage gear 34 and the components fixed thereto. The internal gear 332 is fixedly installed on one side of the outer wall of the inner rotating disk 4 and meshes with the linkage gear 34 inside. The inner rotating disk 4 is rotatably connected to the inside of the outer rotating disk 33 under the action of external force. The differential speed generated when the two rotates allows the inner rotating disk 4 to maintain a self-rotation state during the rotation of the linkage gear 34, thereby effectively adjusting the orientation of the linkage gear 34 and the components fixed thereto.

[0036] In some embodiments, such as Figure 5 and Figure 6 As shown, the top of the fixed frame 35 is provided with a set of movable slots 351. Movable blocks 36 are slidably embedded in the top of each set of movable slots 351. When the movable blocks 36 are limited to their movement within the movable slots 351, they can only slide in one direction. Gear plates 361 are fixedly installed on the top of each set of movable blocks 36, thus ensuring that the gear plates 361 move with the embedded movable blocks 36. The bottom of the inner wall of the fixed frame 35 is provided with a fixed slot 352. A bearing 371 is fixedly installed inside the fixed slot 352. When the bearing 371 is installed inside the fixed slot 352, it is used to maintain the fixed state between the bearing 371 and the fixed frame 35. A rotating rod 372 is fixedly inserted inside the bearing 371. Under the action of the balls inside the bearing 371, the rotating rod 372 can rotate within the bearing 371. The rotating rod 372 is fixedly installed at the bottom of the adjusting gear 373. A micro motor 374 is fixedly installed at the bottom, and the rotating end of the micro motor 374 is fixedly connected to the bottom of the rotating rod 372. During this process, when the spool 324 needs to be replaced, the micro motor 374 starts to drive the rotating rod 372 to rotate. The rotating rod 372 drives the adjusting gear 373 to rotate at the same frequency. The adjusting gear 373 meshes between the two gear plates 361. Under this adjustment, the two gear plates 361 can move inward or outward at the same frequency. An irregular connecting plate 362 is fixedly installed on the top of each set of gear plates 361. An anti-slip plug 363 is fixedly installed on the top of each set of irregular connecting plates 362. Using the irregular connecting plate 362 as a linkage medium, the two anti-slip plugs 363 are driven to move in opposite directions, so that the two anti-slip plugs 363 can be effectively embedded in the inside of the spool 324 to realize the replacement of the spool 324.

[0037] In some embodiments, such as Figure 9 and Figure 10As shown, after the device replaces the bobbin 324, the outer rotating disk 33 rotates as a whole, and the differential speed between the outer rotating disk 33 and the inner rotating disk 4 keeps the bobbin 324 rotating 90 degrees counterclockwise, maintaining a parallel state with the detection mechanism 2. This allows for strong detection of the single yarn wound on the outer wall of the bobbin 324 in conjunction with the detection mechanism 2. Subsequently, the outer rotating disk 33 rotates as a whole, and the differential speed between the outer rotating disk 33 and the inner rotating disk 4 keeps the bobbin 324 in a parallel state. 24 rotates 90 degrees counterclockwise, with itself facing downwards. Driven by the micro motor 374, it operates in the manner described above, causing the two anti-slip plugs 363 to move towards each other, thus disengaging the two anti-slip plugs 363 from the inside of the bobbin 324. This facilitates further processing of the bobbin 324 after the inspection is completed. With a 180-degree rotation and differential speed coordination, the equipment is kept in a final state. When the micro motor 374 is started, a new bobbin 324 is used for further replacement inspection.

[0038] Furthermore, such as Figure 6 and Figure 7 As shown, a side frame 31 is fixedly installed on one side of the outer wall of the mounting plate 1, and a placement component 32 is fixedly installed on one side of the outer wall of the side frame 31.

[0039] The placement assembly 32 includes a placement frame 321, which serves as a placement device for pre-processing the spool 324. During this process, the placement frame 321 has two sets of elastic hinges 322 inside. After the two anti-slip plugs 363 are embedded inside the spool 324, a baffle 323 is fixedly connected to the rotating end of each set of elastic hinges 322. The linkage gear 34 rotates, and under its action, it can pull the two anti-slip plugs 363 and the spool 324 embedded in them out from the bottom of the baffle 323. Furthermore, under the action of the elastic hinges 322, the two baffles 323 quickly... The structure is then restored to prevent other spools 324 from leaking out. Multiple spools 324 are placed inside the placement frame 321. A drive rod 312 is rotatably connected inside the side frame 31. A transmission wheel 313 is fixedly connected to one side of the outer wall of the drive rod 312. A transmission belt 314 is internally connected to the transmission wheel 313. Driven by an external motor, the transmission belt 314 rotates. The rotation of the transmission belt 314 causes the transmission wheel 313 to rotate. The transmission belt 314 is fixed to the drive rod 312. The drive rod 312 is fixed to the outer rotating disk 33, thereby enabling the outer rotating disk 33 to rotate as a whole.

[0040] More specifically: the testing mechanism 2 includes a movable frame 21, and a drive assembly 22 is rotatably connected to the outer wall of the movable frame 21. The drive assembly 22 contains a motor and a gear set. The gear set meshes with the teeth of the movable frame 21, and under the drive of the motor, the drive assembly 22 moves back and forth on the outer wall of the movable frame 21. A rotary motor A23 is fixedly connected to one side of the outer wall of the drive assembly 22. An electrostatic adsorption roller 231 is fixedly connected to the rotating end of the rotary motor A23. When the electrostatic adsorption roller 231 contacts the wire end, electrostatic adsorption keeps the wire end adhered to the outer wall of the electrostatic adsorption roller 231. After the rotary motor A23 drives the electrostatic adsorption roller 231 to rotate, it can effectively wind the single yarn. The other end of the drive component 22 is fixedly connected to the rotary motor B24. The rotating end of the rotary motor B24 is fixedly connected to the rotary roller 241. An electric cutter 242 is fixedly connected to one side of the outer wall of the rotary roller 241. Under the action of the rotary motor B24 driving the rotary roller 241, the single yarn at the middle position of the yarn end and the yarn spool 324 is wound and kept fixed at both ends. After the electrostatic adsorption roller 231 and the rotary roller 241 rotate in opposite directions, the strength test of the single yarn is detected by using the force difference generated by the motor.

[0041] This invention also provides a detection method for a fully automatic integrated device for testing the strength of single yarns, comprising the following steps:

[0042] Step 1: First, place multiple spools 324 inside the placement frame 321 for initial storage. With the help of the components, two anti-slip plugs 363 are inserted into the spools 324 to clamp them.

[0043] Step 2: When the fixed frame 35 rotates with the movement of the linkage gear 34, it adjusts its position and angle to send the spool 324 to an aligned state with the detection mechanism 2;

[0044] Step 3: The testing mechanism 2 is used to wind and stretch the yarn end at the front end of the yarn spool 324 for single yarn strength testing;

[0045] Step 4: During subsequent position transfer, it can be used to move the measured spool 324 and perform new tests on the new spool 324.

[0046] 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.
