Description

Technical Field

[0001] The invention relates to the technical field of detection of wear resistance of outer layers of luggage, and in particular to a testing device and method for detection of wear resistance of outer layers of luggage. Background Art

[0002] During daily travel, especially longer trips, people often need to carry various luggage to meet various daily needs during the trip. Luggage is a container for carrying various items needed for travel. Among them, the most common are trolley roller luggage, which have large capacity and are easy to move and carry, and are widely used during travel.

[0003] With the development of society and the improvement of economic level, people's requirements for luggage are not limited to being sturdy and having a large capacity. People are increasingly pursuing the fashion and aesthetics of luggage. Therefore, various fashionable and beautiful luggage are produced. However, luggage is often in a moving or transporting state during use, so the outer layer of the luggage will inevitably be worn. Once the wear resistance of the outer layer of the luggage is poor, it is easy to be scratched and seriously affect the aesthetics of the luggage. Therefore, it is necessary to test the wear resistance of the outer layer of the luggage.

[0004] However, most of the existing luggage outer layer wear resistance testing equipment is to make the luggage outer layer material into a composite test sample, and then place the test sample into the wear resistance testing equipment for wear resistance testing. Although this testing method can detect the wear resistance of the luggage outer layer material, it cannot simulate the scenario where the luggage is worn during movement, so it is difficult to detect whether the various outer layer parts that are susceptible to wear in various mobile use scenarios have sufficient wear resistance, and it is impossible to detect the wear resistance of the luggage outer layer more accurately and reliably. Therefore, there is an urgent need for a test equipment and method for detecting the wear resistance of the luggage outer layer. Summary of the invention

The advantage of this arrangement is that the two second electric push rods can extend and contract respectively, which can drive the two clamping plates to rotate in opposite directions, and then cooperate with the two first electric push rods to push the two clamping plates to clamp the luggage, so that the luggage can be driven to swing on the vertical plane, so that the edges and corners of the luggage can also rub against the friction plate, so that the wear resistance of the outer layer of the luggage can be more fully and comprehensively tested, effectively improving the test reliability of the test equipment.

[0008] Preferably, the lifting assembly is two third electric push rods symmetrically fixedly connected to the bottom of the two moving blocks. The advantage of this arrangement is that the third electric push rods can stably and reliably drive the luggage to move up and down, thereby ensuring that the wear resistance performance test can be carried out stably, effectively improving the reliability of the testing equipment.

[0009] Preferably, the clamping assembly is provided with a flipping assembly, which is used to drive the two clamping plates to rotate. The advantage of such a configuration is that the luggage can be driven to flip through the flipping assembly so that different sides of the luggage rub against the friction plate, thereby reducing the number of times the staff manually adjusts the position of the luggage, reducing the labor intensity of the staff and improving the testing efficiency of the testing equipment.

[0010] Preferably, an auxiliary detection component is connected to the rotating box, and the auxiliary detection component can detect the wear resistance of a local position on the surface of the bag. The advantage of this arrangement is that the wear resistance of the outer layer of the bag can be tested more fully and thoroughly, greatly improving the test accuracy and reliability of the testing equipment.

A plurality of elastic members are fixedly connected between the sides of the plurality of top plates away from the axis line of the rotating box and the sides of the plurality of mounting blocks. The push-out mechanism also includes a lifting unit connected to the top of the base, and the lifting unit is used to lift up part or all of the plurality of top rods located at the bottom. The advantage of such a configuration is that part or all of the plurality of top rods located at the bottom are lifted up by the lifting unit, so that the friction blocks of various shapes can be rubbed against the outer layer of the luggage in an orderly manner according to the pre-set settings, thereby greatly improving the accuracy and reliability of the wear resistance test.

The advantage of this arrangement is that, through the intermittent extension and retraction of the fourth electric push rod, it can cooperate with the rotation of the rotating box so that each friction block has the opportunity to come into contact and rub against the outer layer of the luggage, so that different friction test schemes can be flexibly designed according to the concave and convex shapes of each side of the outer layer of the luggage, effectively improving the accuracy and reliability of the wear resistance test of the test equipment.

[0014] Preferably, the number of the fourth electric push rods is multiple groups, the number of the fourth electric push rods in each group is equal to the number of rows of the friction blocks in each group and are respectively located directly below a group of multiple rows of friction blocks at the bottom, the number of the push blocks is multiple groups, the bottoms of the multiple groups of push blocks are respectively fixedly connected to the output ends of the multiple groups of fourth electric push rods, the telescopic height of each group of multiple fourth electric push rods and whether to telescope can be set in advance, the lifting unit also includes a bearing plate connected to the top of the base for left and right sliding, the lifting unit also includes a fifth electric push rod fixedly connected to the top of the base, and the output end of the fifth electric push rod is fixedly connected to the right side surface of the bearing plate.

Then the staff rotates the bag so that different sides of the bag can be subjected to friction test with the lowest friction plate. Then the bag is taken out to observe the friction condition to determine whether the wear resistance of the bag is qualified. S5: Then start the rotating assembly to drive the rotating box to rotate clockwise for a certain angle until another friction plate is located directly below the bag, and then repeat the above steps so that all sides of another new bag can be subjected to friction test with the adjusted friction plate; S6: Repeat step S5 until each friction plate has participated in the wear resistance test, so as to comprehensively evaluate whether the wear resistance of the luggage is qualified.
