[0002] As a common bundling tool, nylon cable ties, also known as cable ties, wire ties, cable straps, and tie wraps, are strips made of nylon material (polymer polyamide 66, i.e., nylon PA66). The following is a detailed introduction to nylon cable ties:

[0003] Types and Functions: There are various types of nylon cable ties, which can be divided into multiple types according to different functions. For example: Self-locking nylon cable ties: Designed with a non-retracting function, they can only be tightened more and more. Sign nylon cable ties: Used to fix and label cables or items. Quick-release nylon cable ties: Removable cable ties for convenient reuse. Tamper-proof nylon cable ties: Used in occasions where prevention of disassembly or tampering is required.

Among many performance indicators, tensile strength is one of the important criteria for evaluating the basic performance of nylon cable ties. However, the traditional device for detecting tensile strength still has the following defects:

[0004] When conducting a tensile test on traditional cable ties, since manual bundling of the cable tie and putting it on the tensile test equipment is required for the tensile test of the cable tie, and then the tensile test after bundling is carried out, it is impossible to automatically bundle the cable tie and automatically move it to the tensile test equipment for batch and continuous testing, thus increasing the complexity of the operation of the overall device for conducting the tensile test on the cable tie. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for detecting the tensile strength of nylon cable ties to solve the problem in the above background art that it is impossible to automatically bundle the cable tie and automatically move it to the tensile test equipment for batch and continuous testing, thus increasing the complexity of the operation of the overall device for conducting the tensile test on the cable tie.

[0006] To achieve the above object, the present invention provides the following technical solution: A device for detecting the tensile strength of nylon cable ties, including a base.

On the inner side walls of the outer frame, a driving assembly is provided. On the other side of the top of the base, an outer ring is fixedly installed. On the inner side walls of the outer ring, two internal gear rings are rotatably connected. Inside the two internal gear rings, two electric hydraulic rods are fixedly installed. The telescopic ends of the two electric hydraulic rods are fixedly installed with an outer frame. On the inner side walls of the outer frame, a top plate is fixedly installed. At the bottom end of the top plate, a bottom plate is rotatably connected. On the inner side walls of the bottom plate, a front support plate and a rear support plate are respectively slidably connected. On the tops of the front support plate and the rear support plate, multiple cable tie bodies are provided. On the inner side walls of the outer ring, a rotating assembly is provided.

[0007] To make it more convenient to clamp, fix and release the cable tie body, as a preferred embodiment of the present invention, a reversible motor is fixedly installed on the outside of the outer frame. The output end of the reversible motor is fixedly connected to one side of the bottom plate. On the outside of the front support plate and the rear support plate, multiple electric telescopic rods are fixedly installed. The fixed ends of the multiple electric telescopic rods are fixedly connected to the inner side walls of the bottom plate.

[0008] To make the upper support plate move up and down to conduct a tensile test on the cable tie body, as a preferred embodiment of the present invention, the lifting assembly includes two lifting screw rods rotatably connected to the inner side walls of the test frame. The outer sides of the two lifting screw rods are threadedly connected to the inner side walls of the lifting plate.

[0009] To make the two lifting screw rods rotate in opposite directions relative to each other, as a preferred embodiment of the present invention, the lifting assembly further includes a driving gear fixedly installed at the top end of the lifting screw rod. At the top end of the test frame, a main motor is fixedly installed. The output end of the main motor is fixedly connected to the top end of the lifting screw rod.

[0010] To make the two screw rods rotate in opposite directions relative to each other, as a preferred embodiment of the present invention, the driving assembly includes four intermediate gears rotatably connected to the inner side walls of the outer frame. The inner side walls of two of the intermediate gears are fixedly connected to one end of the screw rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1) Through the action of the front support plate and the rear support plate provided on the two bottom plates, it is more convenient to limit the head and tail of the tie head. After the top plate and the bottom plate rotate and close, and the front support plate slides into the bottom plate, the two ends of the cable tie body can be clamped and fixed. Then, through the rotation of the outer frame driven by the internal gear ring, the tail of the cable tie body can rotate towards the head and insert into the head, so that the required test cable tie can be tied, thereby reducing the tediousness of manually tying the cable tie body.

[0016] 2) Through the action of the feeding column, the tied cable tie body can be guided forward, and at the same time, through the rotation of the two screw rods on the outside of the feeding column, it can be used to drive the cable tie body to move forward slowly. When the upper support plate and the lower support plate are closed, the cable tie body can be driven to move forward quickly to the position of the upper support plate and the lower support plate for the tensile test of the cable tie body, thereby improving the convenience of feeding the cable tie during the overall tensile test.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0028] A device for detecting the tensile strength of nylon tie straps, including a base 1. One side of the top of the base 1 is fixedly installed with a test stand 2. The inner bottom wall of the test stand 2 is fixedly installed with a lower support plate 21. The inner side walls of the test stand 2 are respectively slidably connected with an upper support plate 22 and a lifting plate 23. The bottom end of the lifting plate 23 is fixedly installed with a force measuring sensor 24. The bottom end of the force measuring sensor 24 is fixedly connected with the top end of the upper support plate 22. The inner side wall of the test stand 2 is provided with a lifting assembly 3. The other end of the lower support plate 21 is fixedly installed with a feeding column 4. The outside of the test stand 2 is fixedly installed with an outer frame 5. The inner side wall of the outer frame 5 is rotatably connected with two screw rods 51. The inner side wall of the outer frame 5 is provided with a driving assembly 6. The other side of the top of the base 1 is fixedly installed with an outer ring 7. The inner side wall of the outer ring 7 is rotatably connected with two internal gear rings 8. The inner sides of the two internal gear rings 8 are fixedly installed with two electro-hydraulic rods 81. The telescopic ends of the two electro-hydraulic rods 81 are fixedly installed with an outer frame 9. The inner side wall of the outer frame 9 is fixedly installed with a top plate 91. The bottom end of the top plate 91 is rotatably connected with a bottom plate 92. The inner side walls of the bottom plate 92 are respectively slidably connected with a front support plate 93 and a rear support plate 94. The tops of the front support plate 93 and the rear support plate 94 are provided with multiple tie strap bodies 10. The inner side wall of the outer ring 7 is provided with a rotating assembly 11.

[0029] During specific use, it can be opened to a size suitable for inserting the tie body 10 by rotating the bottom plate 92 at the bottom of the top plate 91 and the inner wall of the outer frame 9. First, place the tie body 10 in the groove of the front support plate 93 according to the head direction, and make its head fit against the inner wall of the top plate 91. Secondly, pass the tail of the tie body 10 through the gap of the bottom plate 92 according to the corresponding sorting of the tie body 10 and bend it downward. At this time, the top plate 91 and the bottom plate 92 can be closed by rotating the bottom plate 92 in the reverse direction, so as to clamp and fix the tie body 10;

[0030] When performing batch bundling operations on the tie body 10, the front support plate 93 can be slid inside the bottom plate 92, so that the head position of the tie body 10 is separated from the front support plate 93, and the head position of the tie body 10 continues to remain in place corresponding to the gaps on the front plate and the rear plate. Then, the electric hydraulic rod 81 drives the outer frame 9 to make an adaptive adjustment in the horizontal position, and the rotating assembly 11 drives the inner gear ring 8 to rotate on the outer frame 9, so that one of the top plate 91 and the bottom plate 92 can drive the tail of the tie body 10 to move towards the head of the tie body 10 on the other top plate 91 and bottom plate 92. After the tail of the tie body 10 is inserted into the head of the tie body 10, when the position where the top plate 91 and the bottom plate 92 fix the tail of the tie body 10 and expose it is short, the top plate 91 and the bottom plate 92 can be opened, and then the electric hydraulic rod 81 drives the movement of the outer frame 9, so that the exposed position of the tie body 10 on the top plate 91 and the bottom plate 92 increases;

[0031] The movement of the outer frame 9 driven by the electric hydraulic rod 81 and the action of the rotating assembly 11 can be continued to insert the tail of the tie body 10 into the head of the tie body 10 and push it forward to an appropriate length. After the bundling of the tie body 10 is completed, the rear support plate 94 can be slid inside the bottom plate 92 to release the limit on the tie body 10. At this time, the bottom plate 92 and the top plate 91 can be opened on the outer frame 9, so that the tie can slide from the bottom plate 92 to the position of the loading column 4;

[0032] Through the inclined guiding of the feeding column 4, the cable tie can be gradually moved towards the position of the screw rod 51. At this time, the pushing operation can be performed to move the cable tie body 10 towards the position of the screw rod 51 one by one. Thus, when the screw rod 51 is driven by the driving assembly 6, the cable tie body 10 can be gradually driven to move slowly forward on the feeding column 4. When the upper supporting plate 22 and the lower supporting plate 21 are mutually attached, the cable tie body 10 at the front end of the feeding column 4 can be quickly driven to the positions of the upper supporting plate 22 and the lower supporting plate 21 by the rotation of the screw rod 51, so as to achieve the feeding function of the cable tie body 10 after bundling. At this time, the cable tie body 10 can drive the lifting of the lifting plate 23 through the lifting assembly 3, so that the upper supporting plate 22 moves upward through the lifting plate 23 to perform a tensile test on the cable tie body 10 after bundling, and at the same time, the tensile force value is recorded by the force measuring sensor 24. After the cable tie body 10 is broken, it can fall downward.

[0033] In this embodiment: A reversible motor 95 is fixedly installed on the outer side of the outer frame 9. The output end of the reversible motor 95 is fixedly connected to one side of the bottom plate 92. A plurality of electric telescopic rods 96 are fixedly installed on the outer sides of the front supporting plate 93 and the rear supporting plate 94. The fixed ends of the plurality of electric telescopic rods 96 are fixedly connected to the inner side wall of the bottom plate 92.

[0034] During specific use, when it is necessary to rotate and open the bottom plate 92 at the bottom of the top plate 91 and inside the outer frame 9, the reversible motor 95 can be started to make the bottom plate 92 rotate to a suitable size position. When it is necessary to move the front supporting plate 93 or the rear supporting plate 94 inside the bottom plate 92, the electric telescopic rod 96 can be driven to slide inside the bottom plate 92, so that the head and tail of the cable tie body 10 can be respectively limited or disengaged, etc.

[0036] During specific use, when it is necessary to drive the upper supporting plate 22 to lift or lower by the lifting plate 23, the relative rotation of the two lifting screw rods 31 can be used to make the upper supporting plate 22 move upward to perform a tensile test on the cable tie body 10, or the upper supporting plate 22 slide downward to fit with the lower supporting plate 21.

[0040] During specific use, when it is necessary for the two screw rods 51 to rotate to drive the displacement of the tie body 10 on the feeding column 4, through the transitional function of the four transitional gears 61, the two screw rods 51 can rotate in opposite directions relative to each other, and then the tie body 10 can be driven to move forward on the feeding column 4 simultaneously.

[0041] In this embodiment: The driving assembly 6 further includes a driving motor 62 fixedly installed on the outer side of the outer frame 5, and the output end of the driving motor 62 is fixedly connected to one end of the transitional gear 61.

[0042] During specific use, when it is necessary for the screw rod 51 to rotate, the driving motor 62 can be turned on to drive the transitional gear 61, so that the four transitional gears 61 rotate simultaneously and then drive the screw rod 51.

[0043] In this embodiment: The rotating assembly 11 includes two secondary gears 111 rotatably connected to the inner side wall of the outer ring 7, and the two secondary gears 111 are engaged with the internal gear ring 8.

[0044] During specific use, when it is necessary to adjust the positions of the head or tail of the tie body 10 by the two internal gear rings 8 respectively, through the drive of the secondary gear 111 at the corresponding required position, the secondary gear 111 can drive the internal gear ring 8 to rotate to a suitable position angle inside the outer ring 7.
