[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] By setting up a carrying mechanism, two wire carrying assemblies are used to carry the sewing threads to be tested in batches, and the carrying assemblies can realize the convenient loading of multiple strands of sewing threads at one time. The two wire carrying assemblies are switched and adjusted under the action of the driving mechanism, and then the sewing threads are tested in batches with the cooperation of the measuring mechanism. Sampling testing is used to realize efficient and comprehensive testing of multiple strands of sewing threads in the same batch, which not only ensures the accuracy of testing the same batch of sewing threads, reduces equipment costs, but also improves the testing efficiency of sewing threads.

[0025] The two thread-carrying assemblies in the bearing mechanism can be displaced and adjusted through the driving mechanism with the cooperation of the adjusting assembly. Therefore, when a large number of sewing threads are to be inspected, multiple strands of sewing threads can be inspected in batches, thereby ensuring the comprehensiveness of the sewing thread inspection. The measuring mechanism also moves under the action of the driving mechanism, and then completes the measurement operation of the sewing thread on the switched thread-carrying assembly with a single drive after the displacement adjustment of the thread-carrying assembly, thereby alleviating the trouble of the existing sewing thread tension inspection.

[0026] The switching adjustment of the two thread-carrying components in the carrying mechanism makes it possible to fully utilize the time for sewing thread detection to achieve loading replacement of the sewing thread to be tested. In the case of detecting a large number of sewing threads, the time consumption can be further reduced and the detection efficiency can be improved.

[0027] When loading the sewing thread, the thread carrier assembly only needs to place it in a standardized manner. The viscose pad arranged on it can pre-fix the sewing thread to avoid displacement or wrinkling of the sewing thread when the thread carrier assembly is switched and adjusted. The setting of the contact rod can squeeze and adjust the clamping part on the thread carrier assembly moved to the detection area, so as to clamp and fix the end of the sewing thread arranged thereon, thereby ensuring the stability of the sewing thread during detection. The convenience of wiring further improves the detection efficiency of the sewing thread.

[0028] The coordination of the movable loading parts and the guide grooves enables the two thread-carrying assemblies to move in an offset manner during switching and adjustment, thereby ensuring the smooth switching and adjustment of the two thread-carrying assemblies. Furthermore, the offset switching of the two thread-carrying assemblies does not affect their positions when they stay in the detection area, thereby ensuring that the measuring mechanism can accurately measure the sewing thread on any thread-carrying assembly.

[0046] The top of the frame 1 is divided into a thread loading area and a detection area, thereby dividing the wiring and detection of the sewing thread to be tested. A bearing mechanism, a driving mechanism 4, a measuring mechanism 5 and a contact rod 6 are installed on the top of the frame 1. Among them, the bearing mechanism is composed of an adjustment component 2 and a thread carrying component 3. There are two adjustment components 2, which are symmetrically arranged on the top of the frame 1.

The driving mechanism 4 is located in the thread loading area, and the measuring mechanism 5 is located in the detection area. The arrangement of the measuring mechanism 5 in the detection area can realize the tension measurement of the sewing thread on the thread carrier assembly 3 that reaches the detection area.

[0048] See also Figure 1-Figure 5 and Figure 7-Figure 9 In an embodiment of the present invention, the adjustment component 2 includes an L-shaped plate 21 fixedly connected to the frame 1 by bolts. A toothed chain component 22 is provided on the outer side of the L-shaped plate 21, and two load-bearing sliders are slidably connected to the L-shaped plate 21.

The setting of the V-shaped notches can realize the wiring and placement of sewing threads of different specifications. A viscose pad 34 located on the inner wall of the rectangular groove is provided between two adjacent wiring strips 33 at the ends. The viscose pad 34 is used for pre-fixing the sewing thread. The viscose pad 34 is only provided to ensure the stability of the sewing thread when it is wired, to avoid the occurrence of deviation when the wire carrier assembly 3 is replaced, and thus the viscose pad 34 does not need to have strong viscosity, and thus will not have an adverse effect on the measurement of the sewing thread.

[0057] The two notches are respectively located at the two side ends of the rectangular groove. The clamping member 35 includes a vertical plate 351 integrally arranged on the inner wall of the notch, and the front and rear sides of the vertical plate 351 are integrally provided with extension plates, each of which is provided with a hole, and a guide rod 352 is movably connected in the hole. A plurality of guide rods 352 are commonly connected to an extrusion plate 353 on one side close to the L-shaped plate 21.

An end plate is installed at the other end of the guide rod 352, and an extrusion spring located on the guide rod 352 is sleeved between the end plate and the vertical plate 351. The setting of the extrusion spring enables the guide rod 352 to automatically reset and adjust when no force is applied. The top of the extrusion plate 353 is slidably connected to the bottom shell wall of the wire carrier plate 31, further ensuring the stability of the displacement of the extrusion plate 353.

The contact rod 6 is mounted on the top of the frame 1 by screws, and a ball is rollingly connected to the top of the contact rod 6. When the wire carrying assembly 3 moves to the detection area, if the double-sided wedge block 36 contacts the ball of the contact rod 6, the contact rod 6 acts to cause the corresponding extrusion plate 353 to adjust its displacement.

[0060] See also Fig.10 , Fig.11 and Fig.13 In the embodiment of the present invention, the driving mechanism 4 includes an electric push rod 41 disposed on the frame 1.

The arrangement of the telescopic rod 545 ensures the stability of the force-bearing movement of the measuring spring 543.

[0070] The working principle of the present invention is: when measuring the tension of a large number of sewing threads, the controller body arranged on the frame 1 is used to first calibrate each tension measuring component 54 in the measuring mechanism 5 to ensure its accuracy when measuring the tension of the sewing threads.

[0071] After the tension measuring assembly 54 is calibrated, each sewing thread to be tested is arranged in a standardized manner in the thread carrying assembly 3 in the thread loading area. When the sewing thread is routed on the thread carrying assembly 3, it is arranged and arranged according to each routing line 33 arranged thereon, and after the sewing thread is arranged, its two ends pass through the corresponding notches respectively, and after the sewing thread is arranged in a standardized manner, the contact between it and the adhesive pad 34 is realized to pre-fix it. This prevents the arranged sewing thread from being scattered with the switching of the thread carrying assembly 3.

[0072] After the thread-carrying assembly 3 in the thread-loading area has completed the arrangement of the sewing thread to be tested, the electric push rod 41 in the driving mechanism 4 is started through the controller body. The operation of the electric push rod 41 causes the sliding frame 42 to move, and when the sliding frame 42 is in the moving state at this time, the rack 44 and the gear 46 arranged thereon are meshed and transmitted, thereby driving the transmission shaft to move. When the transmission shaft rotates, the swing arm 47 arranged thereon is synchronously moved, and the integration plate 49 is linearly moved through the connecting rod 48. The movement of the integration plate 49 causes the bearing slider connected thereto to move synchronously, and the bearing slider is connected to the toothed chain member 22 through the splicing plate 23, thereby causing the toothed chain member 22 to move. Thus, the station switching adjustment of the two thread-carrying assemblies 3 is realized.

[0073] When the electric push rod 41 outputs one-third of the mileage, the rack 44 and the gear 46 are disengaged, and then the swing arm 47 and the connecting rod 48 enable the integration plate 49 to complete the displacement adjustment, thereby realizing the switching of the two wire-carrying assemblies 3 to achieve the working position.

[0074] When the workstation of the thread carrier assembly 3 is switched, the thread carrier assembly 3 on which the sewing thread to be tested is arranged moves from the thread loading area to the detection area. At this time, when the thread carrier assembly 3 that has completed the arrangement of the sewing thread is moved and adjusted, due to the cooperation of the guide groove, the convex rod and the movable loading member 24, it moves downward when it moves to the detection area, and then the single-sided wedge block 37 on the clamping member 35 of the thread carrier assembly 3 squeezes the corresponding contact rod 6, so that the squeezing plate 353 in the corresponding clamping member 35 is forced to move. After the squeezing plate 353 is forced, it moves with the cooperation of the corresponding guide rod 352, stretching the squeezing spring, and then the squeezing plate 353 clamps and fixes the end of the sewing thread passing through the notch. In this way, the end of the sewing thread to be tested is locked and limited.

[0075] After the two wire-carrying assemblies 3 have completed the switching adjustment, the controller body drives the electric push rod 41 to continue to operate. Then the sliding frame 42 continues to move. At this time, since the rack 44 and the gear 46 are out of mesh, the integration plate 49 will not be driven to move. The continuous movement of the sliding frame 42 causes the extrusion wedge 45 configured thereon to move accordingly. During the displacement process, the extrusion wedge 45 contacts the rod body of the adjustment member 57 in the measuring mechanism 5, and then with the continuous movement of the extrusion wedge 45, the rod body in the adjustment member 57 is forced to move, squeeze the reset spring, and drive the support 56 to move.

[0076] After the support 56 is subjected to force movement, the vertical plate 55 moves upward through the movement of the slide rod in the inclined groove of the vertical plate 55, and the upward movement of the base plate 53 is realized synchronously. When the base plate 53 moves upward, the multiple tension measuring components 54 arranged thereon move synchronously. After each tension measuring component 54 moves upward, its top plate 544 contacts the corresponding sewing thread. As the base plate 53 moves upward, each sewing thread contacts the top plate 544 and moves downward with the cooperation of the telescopic rod 545, compressing the measuring spring 543 and making the bottom plate 542 contact the pressure sensor body 541. The force exerted on each pressure sensor body 541 is transmitted to the controller body, and the tension of each sewing thread to be measured is calculated.

[0077] After the wire carrier assembly 3 is switched, the original sewing thread of the wire carrier assembly 3 newly entering the wire loading area is first removed, and then the new sewing thread to be tested is wired. When the sewing thread on the wire carrier assembly 3 located in the detection area is measured, the reverse movement of the electric push rod 41 in the driving mechanism 4 is started again through the controller body. In the one-third of the return journey of the electric push rod 41, the measuring mechanism 5 is reset first, and then the switching adjustment of the two wire carrier assemblies 3 is realized in the one-third to two-thirds of the return journey. Finally, the measuring mechanism 5 is activated again in the last one-third of the return journey of the electric push rod 41, so as to measure the sewing thread to be tested on the wire carrier assembly 3 after the switching is completed. The cycle is repeated to achieve the tension measurement of a large number of sewing threads.

[0078] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
