[0016] The technical solution of the utility model is further described below by way of embodiments:
[0017] The utility model provides a folding resistance testing machine, combined with Figures 1-2 As shown, the folding resistance testing machine includes: a base 1, a folding plate 2, a support plate 3, a driving mechanism 4 and an adjusting mechanism 5. The base 1 includes: a base plate 11 and a partition plate 12. The partition plate 12 is fixed to the base plate 11. The driving mechanism 4 is connected to the folding plate 2 to drive the folding plate 2 to perform a reciprocating folding action relative to the support plate 3. The adjusting mechanism 5 includes: an adjusting bracket 51 and an adjusting screw 52. The support plate 3 is fixed to the adjusting bracket 51. The adjusting bracket 51 is provided with strip holes 511 arranged in the up and down directions. The partition plate 12 is provided with a screw hole 121. The adjusting screw 52 passes through the strip hole 511 and engages with the screw hole 121.
[0018] When using the folding resistance testing machine, first rotate the folding plate 2 to a predetermined angle required for the test, the predetermined angle being greater than 0° and less than or equal to 180°, then fix the first part of the flexible product on the supporting plate 3, and fix the second part of the flexible product on the folding plate 2, so that the two parts of the flexible product are bent into a predetermined angle, then use the driving mechanism 4 to control the folding plate 2 to perform a reciprocating folding action relative to the supporting plate 3, and record the number of reciprocating foldings at the same time, and finally judge whether its folding resistance performance meets the requirements based on the situation of the flexible product after reaching the predetermined number of reciprocating foldings. The above working principle is similar to the prior art and will not be described in detail here. Unlike the prior art, the folding resistance testing machine of the utility model can use the adjustment mechanism 5 to adjust the height of the support plate 3 to adapt to flexible products of different thicknesses. Specifically, when testing a flexible product with a larger thickness, the adjusting screw 52 can be loosened, the support plate 3 can be moved downward and then the adjusting screw 52 can be tightened to make the support plate 3 further away from the folding plate 2, and the gap between the support plate 3 and the folding plate 2 can provide a larger deformation space for the crease position of the flexible product; when testing a flexible product with a smaller thickness, the adjusting screw 52 can be loosened, the support plate 3 can be moved upward, so that the support plate 3 is closer to the folding plate 2, and the gap between the support plate 3 and the folding plate 2 matches the deformation space required for the crease position of the flexible product.
[0019] Specifically, the adjustment mechanism 5 further includes: a limiting frame 53, which is in an inverted U shape and is provided with a limiting groove 531, in which a part of the adjustment bracket 51 is located. The setting of the limiting frame 53 can guide the movement of the adjustment bracket 51 on the one hand, and limit the upper limit of the upward movement of the adjustment bracket 51 on the other hand, so as to prevent the support plate 3 and the folding plate 2 from being too close to each other and thus failing to fold the flexible product smoothly.
[0020] Specifically, Figure 3 As shown, the driving mechanism 4 includes: a driving bracket 41, a driving shaft 42, a coupling 43, a reducer 44 and a servo motor 45. The motor shaft of the servo motor 45 is fixed to the input shaft of the reducer 44, the output shaft of the reducer 44 is connected to the driving shaft 42 through the coupling 43, the driving shaft 42 is fixed to the driving bracket 41, and the driving bracket 41 is fixed to the folding plate 2. The servo motor 45 can drive the folding plate 2 to rotate around the driving shaft 42, thereby realizing the folding action; the servo motor 45 and the reducer 44 can cooperate to accurately control the folding angle.
[0021] More specifically, the driving mechanism 4 further includes: an induction ring 46, which is fixed to the driving shaft 42, and is provided with an induction sheet 461; the base 1 further includes: two proximity switches 13, which are arranged opposite to each other, and the induction sheet 461 is located between the two proximity switches 13. During the rotation of the folding plate 2, the induction sheet 461 will move between the two proximity switches 13, and when the induction sheet 461 approaches the proximity switch 13, a trigger signal will be generated, thereby recording the number of times the flexible product is folded.
[0022] For more details, please refer to Figure 1 As shown, the base 1 also includes: a chassis 14, and the coupling 43, the reducer 44, the servo motor 45, and the two proximity switches 13 are all located inside the chassis 14. Among them, the chassis 14 can protect the coupling 43, the reducer 44, the servo motor 45, and the two proximity switches 13.
[0023] More specifically, combined with Figures 2-3 As shown, the driving mechanism 4 further includes: a bearing 47; the partition plate 12 is further provided with a through hole 122, the driving shaft 42 passes through the through hole 122, and the bearing 47 is located between the driving shaft 42 and the through hole 122. The provision of the bearing 47 can make the rotation of the driving shaft 42 smoother.
[0024] For details, please continue to refer to Figure 1 As shown, the base 1 also includes: two elastic limit blocks 15, both of which are fixed to the upper surface of the base plate 11 and are respectively located directly below the folding plate 2 and the support plate 3. The elastic limit blocks 15 can limit the lower limit position of the folding plate 2 and the support plate 3 to prevent the folding plate 2 and the support plate 3 from colliding with the base plate 11. In this embodiment, the elastic limit blocks 15 are formed of a urea rubber material.
[0025] Specifically, the base 1 further includes: a plurality of supporting legs 16, and the plurality of supporting legs 16 are fixed to the lower surface of the substrate 11. The supporting legs 16 can prop up the substrate 11 to prevent the substrate 11 from directly contacting the work surface.
