[0028] Please also refer to Figure 1 and Figure 2 , a winding device for detecting the breaking strength and elongation at break of raw silk provided by a preferred embodiment of the present utility model, includes a fixed seat 10, a raw silk winding member 20, a thread head fixing member 31 and a thread tail fixing member 32.

[0029] Please refer to Figure 3 and Figure 7, the fixing base 10 is used to be mounted on a blackboard shaker 200. The number of the fixing bases 10 is two, and the two fixing bases 10 are arranged oppositely. On the same side of the fixing base 10, a first slot 11 and a second slot 12 are provided at intervals. In this embodiment, the first slot 11 and the second slot 12 are respectively arranged at opposite ends of the fixing base 10; specifically, the fixing base 10 includes a fixing plate 13 and two socket connectors 14 respectively fixed at opposite ends of the fixing plate 13. The first slot 11 and the second slot 12 are respectively opened on the two socket connectors 14. Among them, both the first slot 11 and the second slot 12 penetrate through the side of the corresponding socket connector 14 facing the other fixing base 10 to form a socket 15 for inserting the raw silk winding member 20. In addition, in this embodiment, the first slot 11 also penetrates through the side of the corresponding socket connector 14 facing away from the other socket connector 14 to form a movable opening 16, and the movable opening 16 can allow the raw silk winding member 20 to enter and exit the first slot 11.

Specifically, the positioning hole 17 is arranged on the side of the fixing plate 13 facing away from the other fixing base 10. The positioning hole 17 is used for inserting and mating with a positioning block 230 on a clip 210 of a blackboard shaker 200 to position the winding device for detecting the breaking strength and elongation at break of raw silk. The side of the fixing base 10 away from the other fixing base 10 is also spaced from the corresponding socket connector 14, that is, the socket connector 14 is arranged on the side of the corresponding fixing base 10 close to the other fixing base 10 to reserve a space for the clip 210 of the blackboard shaker 200 to clamp.

[0030] Please refer to Figure 5 , the number of the raw silk winding members 20 is two, and the two raw silk winding members 20 are arranged parallel and oppositely. The opposite ends of the raw silk winding member 20 are respectively detachably connected to the two fixing bases 10. In this embodiment, the raw silk winding member 20 is generally in the shape of a long strip plate, and the raw silk winding member 20 is perpendicular to the fixing base 10. The opposite ends of one raw silk winding member 20 are respectively inserted into the first slots 11 of the two fixing bases 10, and the opposite ends of the other raw silk winding member 20 are respectively inserted into the second slots 12 of the two fixing bases 10, so as to be detachably connected to the two fixing bases 10 together, so as to position the raw silk winding member 20 through the two fixing bases 10 and prevent the raw silk winding member 20 from accidentally moving during raw silk winding. In this embodiment, two mounting holes 21 are also provided on the raw silk winding member 20 at intervals. The two mounting holes 21 are both located between the two fixing bases 10 and are arranged at intervals along the length direction of the raw silk winding member 20. In this embodiment, both the raw silk winding member 20 and the fixing base 10 are made of PVC plastic.

[0031] Please refer to Figure 4 and Figure 6, the leading-end fixing member 31 and the trailing-end fixing member 32 are disposed on one of the raw silk winding members 20 and are spaced apart along the length direction of the raw silk winding member 20. In the present embodiment, the leading-end fixing member 31 and the trailing-end fixing member 32 have the same structure and both include an elastic clip 34. The elastic clip 34 is fixed to the raw silk winding member 20, and the elastic clip 34 can clamp the leading end or the trailing end of the raw silk between the elastic clip 34 and the raw silk winding member 20. Specifically, the elastic clip 34 includes a clamping body 341 and two guiding portions 345 respectively fixed to opposite ends of the clamping body 341; the clamping body 341 is generally in a plate shape, and the clamping body 341 is connected to the raw silk winding member 20 through a connecting member 35. In the present embodiment, the clamping bodies 341 of the leading-end fixing member 31 and the trailing-end fixing member 32 are respectively located on opposite sides of the raw silk winding member 20, the clamping body 341 is substantially parallel to the raw silk winding member 20, and the clamping body 341 is provided with a fixing hole 342; the connecting member 35 is a bolt, which includes a screw rod 351 and a nut 352. The screw rod 351 passes through the fixing hole 342 of the corresponding clamping body 341 and the mounting hole 21 on the raw silk winding member 20 and is locked by the nut 352. The guiding portion 345 gradually tilts away from the raw silk winding member 20 in a direction away from the clamping body 341 to form a guiding opening 346; in the present embodiment, the guiding portion 345 and the clamping body 341 are integrally formed. The leading end or the trailing end of the raw silk can enter between the clamping body 341 and the fixed seat 10 through the guiding opening 346, so as to be clamped by the elastic clip 34; the raw silk can also be wound around the screw rod 351 for multiple turns to further prevent the leading end or the trailing end of the raw silk from coming off. Preferably, the elastic clip 34 can be made of a material with elastic deformation ability such as stainless steel.

[0032] During the detection test process, first, assemble the winding device for detecting the breaking strength and breaking elongation rate of raw silk. Specifically, insert one end of the two raw silk winding members 20 into the first slot 11 and the second slot 12 of one of the fixed seats 10 through the corresponding sockets 15 respectively, and then insert the other ends of the two raw silk winding members 20 into the first slot 11 and the second slot 12 of the other fixed seat 10 through the corresponding sockets 15 respectively.

[0033] Then, the winding device for detecting the breaking strength and elongation at break of raw silk is fixedly installed on a blackboard winding machine 200. In this embodiment, the structure of the blackboard winding machine 200 belongs to the prior art. For example, reference can be made to a blackboard winding machine disclosed in a Chinese utility model with an application number of 202222725429.X. When installing the winding device for detecting the breaking strength and elongation at break of raw silk, the two fixing seats 10 are respectively clamped on the two clips 210 of the blackboard winding machine 200, such that the movable opening 16 of the first slot 11 faces upward, and the positioning block 230 of the clip 210 is inserted into the positioning hole 17, thereby preventing the fixing seat 10 from moving up and down randomly. The end of the raw silk on the silk bobbin (not shown in the figure) is clamped on the end fixing member 31. Start the blackboard winding machine 200, and the blackboard winding machine 200 drives the winding device for detecting the breaking strength and elongation at break of raw silk to rotate and drives the yarn bobbin to transport and translate through the yarn bobbin translation mechanism, so as to evenly wind the raw silk on the two raw silk winding members 20. After winding is completed, fix the end of the silk on the end fixing member 32. Both the raw silk winding member 20 and the fixing seat 10 in this embodiment are made of PVC plastic, making their quality lighter. After verification, the friction force between the raw silk winding member 20 and the fixing seat 10 can prevent the raw silk winding member 20 from moving relative to the fixing seat 10 due to centrifugal force or being thrown out from the movable opening 16.

[0034] Finally, remove the winding device for detecting the breaking strength and elongation at break of the wound raw silk from the blackboard winding machine 200, and clamp the two raw silk winding members 20 of the winding device for detecting the breaking strength and elongation at break of raw silk on the upper and lower holders of a constant rate of elongation tester (CRE); pull the two fixing seats 10 away from the two raw silk winding members 20, and then the detection of the breaking strength and elongation at break can be started. The setting of the movable opening 16 enables the raw silk winding member 20 to move away from the other raw silk winding member 20 through the movable opening 16 under the drive of the constant rate of elongation tester during the detection, thereby avoiding damage to the sensor on the constant rate of elongation tester due to overload caused by operation errors (such as finding that the fixing seat 10 has not been pulled away from the raw silk winding member 20) during the detection process.

[0035] When the above-mentioned winding device for detecting the breaking strength and elongation at break of raw silk is in use, the two fixed seats 10 are installed on a blackboard winding machine 200. The end of the raw silk is connected to the end fixing member 31. The blackboard winding machine 200 drives the winding device for detecting the breaking strength and elongation at break of raw silk to rotate, so as to evenly wind the raw silk on the two raw silk winding members 20. During the detection, the two raw silk winding members 20 of the above-mentioned winding device for detecting the breaking strength and elongation at break of raw silk are respectively installed on the upper and lower holders of the constant rate of elongation tester, and then the fixed seat 10 is removed from the raw silk winding member 20 to start the detection. Compared with the manual operation of the prior art, the above-mentioned winding device for detecting the breaking strength and elongation at break of raw silk enables the silk strip to be free from manual auxiliary clamping, achieves mechanical uniform arrangement, effectively solves the problems that the silk strips are too concentrated, unevenly arranged and the tightness of the silk strips is inconsistent during the detection, which easily causes the raw silk to shift during the test, cannot break simultaneously when pulled, resulting in a decrease in the tensile force value and fluctuations in the elongation at break, and can improve work efficiency.

[0036] For the above-mentioned winding device for detecting the breaking strength and elongation at break of raw silk, the end fixing member 31 and the tail fixing member 32 are arranged on the same raw silk winding member 20, so that the silk thread wound on the two raw silk winding members 20 is an integer number of turns, thus meeting the inspection requirements for the breaking strength and elongation at break in the national standard GB / T 1798-2008 "Test Methods for Raw Silk".

[0037] For the above-mentioned winding device for detecting the breaking strength and elongation at break of raw silk, the end fixing member 31 and the tail fixing member 32 adopt elastic clip pieces 34, which can conveniently and quickly fix the end or the tail. The setting of the guiding port 346 can conveniently guide the raw silk between the clamping body 341 and the raw silk winding member 20 to achieve clamping.

[0038] It can be understood that in other embodiments, the end fixing member 31 and the tail fixing member 32 can also be provided on both of the two raw silk winding members 20.

[0039] It can be understood that in other embodiments, the raw silk winding member 20 can also be detachably connected to the fixed seat 10 in other ways, such as snap connection.

[0040] It can be understood that the end fixing member 31 and the tail fixing member 32 can also adopt other structures. For example, the end fixing member 31 and the tail fixing member 32 can be annular. At this time, the raw silk can be connected to the end fixing member 31 and the tail fixing member 32 by tying or other means. The structures of the end fixing member 31 and the tail fixing member 32 can also be different, as long as they can fix the end or the tail.

[0041] It can be understood that the connecting member 35 is not limited to the bolt of this embodiment, and it can also be a rivet or the like, as long as it can fix the elastic clip 34 on the raw silk winding member 20.

[0042] The above description is a detailed description of the preferred and feasible embodiment of the present invention, but the embodiment is not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the scope of the patent covered by the present invention.
