During the bending experiment, the electric heating band needs to be reciprocally bent for multiple times, and then it is observed whether the electric heating band subjected to multiple bending appears undesirable phenomena such as wrinkling, cracking, whitening, etc. If the undesirable phenomena appear, it is determined that the product is a defective product.

[0028] Most of the existing bending experiments are manually operated by personnel, which not only has high labor intensity, low test efficiency, and inaccurate test results, but also cannot guarantee the accuracy and precision of the bending angle.

[0029] Embodiment one:

[0030] The embodiment of the utility model relates to a bending experiment testing device.

[0031] Compared with the prior art, the embodiment of the utility model adopts a clamping piece to fix the product to be tested on a linkage belt, thereby starting a driving piece to drive a rotating disc to rotate, so that the rotating disc drives the linkage belt to move around the rotating disc, thereby causing the product to be tested to move with the linkage belt and be subjected to bending deformation, realizing automatic bending test, reducing personnel cost, and using mechanical transmission to drive the product to be tested to bend and deform, which is more conducive to cyclic bending experiment test, and the test process can be kept consistent each time, which not only accelerates the operation speed of the bending experiment, but also greatly shortens the experimental period, significantly enhances the reliability and stability of the experimental results, thereby improving the test reliability, greatly reducing the personnel cost, and improving the product detection efficiency.

[0032] The implementation details of the testing device of the embodiment will be described in detail below, and the following content is only provided for the implementation details for the convenience of understanding, and is not essential for implementing the scheme.

[0033] The embodiment of the utility model provides a bending experiment testing device, such as Figure 1 and Figure 2As shown, it includes: a base 1, a rotating mechanism 2, a linkage belt 3, and a clamping member 4; wherein, the rotating mechanism 2 includes a rotating disk 21 disposed on the base 1 and a driving member 22 for driving the rotating disk 21 to rotate; the linkage belt 3 is fitted and wrapped around the outer circular surface of the rotating disk 21 so as to move around the rotating disk 21 following the rotation of the rotating disk 21; the clamping member 4 is installed on the linkage belt 3 and is used to fix the product to be tested on the linkage belt 3, so that when the linkage belt 3 moves around the rotating disk 21, the product to be tested will flex and deform with the movement of the linkage belt 3.

[0034] Furthermore, the testing device also includes a counter 5, which is connected to the drive component 22 and is used to record the number of rotation experiments of the rotating disk 21 by monitoring the state of the drive component 22. In this embodiment, after the drive component 22 drives the rotating disk 21 to rotate clockwise once and then counterclockwise once, it is recorded as one flexural deformation test of the product under test. Based on this, the drive component 22 can drive the rotating disk 21 to rotate alternately clockwise and counterclockwise; the counter 5 records the number of times the drive component 22 drives the rotating disk 21 to complete the alternating rotation as the number of rotation experiments of the rotating disk 21; wherein, one alternating rotation of the rotating disk 21 is the rotation of the rotating disk 21 from one clockwise rotation to one counterclockwise rotation. By using the counter 5 to automatically record the number of tests, accurate counting is achieved and the efficiency of automated testing is improved.

[0035] Furthermore, the testing device also includes a control switch 6; the control switch 6 is connected to the drive component 22 and is used to control the start and stop of the drive component 22.

In the embodiment, the driving motor 221 adopts a step motor, so as to control the rotating disc 21 to rotate clockwise and counterclockwise. When the time consumption of the analysis driving click clockwise and counterclockwise is N seconds, the relay 222 can be combined with the N seconds to accurately control the driving motor 221 to reverse, so as to realize the smooth alternation of the clockwise and counterclockwise, thereby facilitating the cyclic bending deformation test of the product to be tested for multiple times, and improving the test efficiency.

[0038] Specifically, the rotating disc 21 includes two roller discs arranged at a preset interval distance on the surface of the base 1, one of the two roller discs being connected with the driving motor 221, so as to be driven to rotate by the driving motor 221. The linkage belt 3 is an annular belt, which is integrally and tightly arranged on the outer circular surface of the two roller discs, so as to move following the rotation of the roller discs, thereby being able to drive the linkage belt 3 to move and synchronously drive the other roller disc to rotate when the driving motor 221 drives one of the roller discs to rotate.

[0039] In order to facilitate the fixation of the product to be tested, the clamping member 4 includes a first clamp 41 and a second clamp 42 in the embodiment. The first clamp 41 and the second clamp 42 are arranged on the linkage belt 3 and located on the two sides of the line connecting the center points of the two roller discs, so as to respectively fix the two ends of the product to be tested. Specifically, the first clamp 41 and the second clamp 42 each include a connecting block 43 fixed on the linkage belt 3 and a bolt assembly 44 arranged on the connecting block 43. The bolt assembly 44 is used for fixing the product to be tested on the connecting block 43. Through the installation of the bolt assembly 44, the product to be tested can be conveniently disassembled and assembled on the connecting block 43, thereby improving the convenience of operation and use.

[0040] Further, the distance between the first clamp 41 and the two roller discs, and the distance between the second clamp 42 and the two roller discs are both greater than the outer circumference of the roller disc, so that the first clamp 41 and the second clamp 42 will not contact the roller disc when the roller disc rotates one circle, thereby ensuring that the product to be tested can be stably tested for multiple times, and improving the test convenience.

[0041] The bending experiment test device provided by the embodiment adopts the clamping piece 4 to fix the product to be tested on the linkage belt 3, so as to start the driving piece 22 to drive the rotating disc 21 to rotate, so that the rotating disc 21 drives the linkage belt 3 to move around the rotating disc 21, so that the product to be tested moves with the linkage belt 3 to be bent and deformed, the bending test is automatically performed, the personnel cost is reduced, the product to be tested is bent and deformed by mechanical transmission, the bending experiment test can be repeatedly performed more times, the test process can be kept consistent each time, the operation speed of the bending experiment is accelerated, the experiment period is greatly shortened, the reliability and stability of the experiment result are significantly enhanced, the test reliability is improved, the personnel cost is greatly reduced, and the product detection efficiency is improved. In addition, the counter 5 is also provided, which can automatically record the test times and realize accurate counting.
