[0002] During the production and R&D testing of luggage, it is necessary to test the surface impact resistance of the luggage. By filling the luggage with fillers of different hardness and softness, and allowing the impact object to fall freely from a specified height onto the surface of the luggage, it is used to simulate whether the surface impact resistance of the luggage is qualified when the luggage is filled with fillers of different hardness and softness, and whether the protection effect of the luggage on the internal fillers is qualified.

[0024] Example 1

[0025] A performance testing device for bag production, such as Figure 1-Figure 6As shown, it includes a card plate 1, a side plate 11, an impact block release mechanism, a mounting plate 31, a column 32, a first electric lift 33, a lifting plate 41, a support plate 42, an impact plate 43, an air bag 5, and an air pressure control mechanism; a side plate 11 for clamping a bag body 9 is bolted to each of the left and right sides of the card plate 1; the impact block release mechanism is connected to the card plate 1; a mounting plate 31 is provided on the card plate 1; four columns 32 are bolted to the mounting plate 31; a lifting plate 41 is placed between the upper ends of the four columns 32; four first electric lifts are installed on the mounting plate 31 33; the telescopic ends of the four first electric-controlled elevators 33 are fixedly connected to a lifting plate 41; two support plates 42 are welded to the front and rear sides of the lifting plate 41; an impact plate 43 is placed on the two support plates 42; a lower buffer pad 34 is fixedly connected to the bottom of the mounting plate 31; an upper buffer pad 44 is fixedly connected to the top of the impact plate 43; a side buffer pad 45 is fixedly connected to the upper ends of the four support plates 42 that are close to the impact plate 43; an air bag 5 is fixedly connected between the lifting plate 41 and the impact plate 43; a pneumatic control mechanism is connected to the card plate 1; the pneumatic control mechanism is connected to the air bag 5.

[0026] like Figure 1 As shown, the impact block release mechanism includes a vertical track 2, an electric lifting slider 21 and an electric-controlled magnetic absorber 22; the vertical track 2 is installed on the clamping plate 1; the electric lifting slider 21 is slidably connected to the vertical track 2; and the electric-controlled magnetic absorber 22 is installed on the electric lifting slider 21.

[0027] like Figure 4 As shown, the air pressure control mechanism includes a cylinder 61, a control valve 62 and an air pump 63; the cylinder 61 and the air pump 63 are sequentially mounted on the mounting plate 31; the air delivery end of the cylinder 61 is connected to the control valve 62, the cylinder 61 is filled with buffer gas, and the control valve 62 is initially in a closed state; the control valve 62 is connected to the air outlet end of the air pump 63 through a pipeline, and the air inlet end of the air pump 63 is connected to the air bag 5 through a pipeline.

[0028] During use, first Figure 2 As shown, the inspector places the mounting plate 31 and the lifting plate 41, impact plate 43, air bag 5, and air pressure control mechanism connected thereto into the luggage body 9, and the mounting plate 31 is pressed against the bottom of the luggage body 9 via the lower buffer pad 34. After the luggage body 9 is covered, the inspector magnetically attracts the impact block to the electric-controlled magnetic absorber 22 through electromagnetic attraction, and the electric lifting slider 21 drives the impact block magnetically attracted on the electric-controlled magnetic absorber 22 to rise to a specified height along the vertical track 2.

[0029] During the hard impact test, the first electrically-controlled elevator 33 pushes the lifting plate 41 to drive the support plate 42 and the impact plate 43 to rise upward until the impact plate 43 is close to the top of the bag body 9 through the upper buffer pad 44. At this time, the lifting plate 41 directly provides hard support to the impact plate 43 through the support plate 42 and the side buffer pad 45. Then the electrically-controlled magnetic absorber 22 disconnects the electromagnetic attraction between the impact block and the released impact block falls downward on the surface of the bag body 9 with free fall. At this time, the impact torque on the surface of the bag body 9 will be directly transmitted to the impact plate 43, and the bag body 9 obtains hard support from the impact plate 43, thereby completing the hard impact test when the inside of the bag body 9 is a hard filler. After that, the inspector can know the impact resistance of the bag body 9 by checking whether the surface of the bag body 9 is damaged.

[0030] During the soft impact test, the control valve 62 controls the cylinder 61 to release the buffer gas outward, and the released buffer gas flows through the air pump 63 and is injected into the air bag 5. As the air bag 5 continues to expand, the air bag 5 replaces the lifting plate 41 to drive the impact plate 43 to rise upward until the impact plate 43 is close to the top of the bag body 9 through the upper buffer pad 44. At this time, the lifting plate 41 provides soft support for the impact plate 43 through the air bag 5 injected with buffer gas, and then the electric-controlled magnetic absorber 22 disconnects the electromagnetic attraction between it and the impact block, and the released impact block falls freely. The body moves downward and falls on the surface of the bag body 9. At this time, the impact torque on the surface of the bag body 9 will be directly transmitted to the impact plate 43, and the bag body 9 will obtain soft support from the impact plate 43, so as to complete the soft impact test when the inside of the bag body 9 is filled with soft fillings. After that, the inspection personnel can know the impact resistance of the bag body 9 by checking whether the surface of the bag body 9 is damaged. After completing the soft impact test, under the control of the control valve 62, the buffer gas injected into the air bag 5 can be reversely transported to the cylinder 61 through the air pump 63.

[0031] When changing the hardness of the support of the impact plate 43 on the bag body 9, the lifting plate 41 can be pushed by the first electrically controlled elevator 33 to drive the air bag 5 and the impact plate 43 to rise upward, and the air pressure control mechanism can control the air bag 5 to drive the impact plate 43 to rise upward, so that the air bag 5 can drive the impact plate 43 upward and close to the top of the bag body 9 on the basis of reducing the amount of buffer gas filled. At this time, the closer the distance between the support plate 42 on the lifting plate 41 and the impact plate 43, the less buffer gas is filled in the air bag 5, and the smaller the soft support effect provided by the air bag 5 to the impact plate 43 through the buffer gas. Therefore, in the impact test work, the soft support effect provided by the impact plate 43 on the bag body 9 is closer to the hard support effect provided by the impact plate 43 on the bag body 9, so that the hardness of the support effect of the impact plate 43 can be adjusted, so that the hardness of the filling material in the bag body 9 can be adjusted quickly and repeatedly in any combination according to the program, thereby improving the richness of the filling scenes that can be selected in the bag body 9 during the test work.

[0032] Example 2

[0033] On the basis of Example 1, Figure 1-Figure 6 As shown, each of the four columns 32 of this embodiment is slidably connected to a limit slide rod 71; the upper ends of the four limit slide rods 71 ​​are commonly bolted to the impact plate 43; a fixing frame 72 is welded between the four limit slide rods 71; each of the four corners of the fixing frame 72 is connected to a damper 73; four second electrically-controlled lifts 74 corresponding to the dampers 73 are installed on the mounting plate 31; the telescopic parts of the four second electrically-controlled lifts 74 are respectively fixed to the telescopic parts of the corresponding dampers 73.

[0034] During the soft impact test, the air bag 5 continuously injected with buffer gas continuously pushes the impact plate 43 upward away from the lifting plate 41 and the support plate 42. At the same time, the telescopic end of the second electrically controlled lift 74 drives the damper 73 and the second pressure sensor 82 to move upward along with the limit slide and fixing frame 72 connected to the impact plate 43. Then, when the impact block hits the top of the luggage body 9, the impact plate 43 will transfer part of the impact torque to the lifting plate 41 through the air bag 5. At the same time, the impact plate 43 will transfer another part of the impact torque to the damper 73 through the limit slide 71 and the impact plate 43. The damper 73 cooperates with the air bag 5 injected with buffer gas to absorb and reduce the impact torque. The filling inside the simulated luggage body 9 is soft objects with excellent energy absorption effect, such as clothes and sponges, to improve the simulation test effect of the soft impact test of the luggage body 9.

[0035] Example 3

[0036] On the basis of Example 2, Figure 1-Figure 6As shown, a first pressure sensor 81 is installed on the top of each of the four columns 32 of this embodiment; the four support plates 42 are all set to an L-shaped structure, and the bottoms of the four support plates 42 are respectively close to a corresponding first pressure sensor 81; a second pressure sensor 82 is installed on each of the four corners of the fixing frame 72; the fixed shell parts of the four dampers 73 are respectively fixed to the corresponding second pressure sensors 82; four third pressure sensors 83 are installed on the lifting plate 41; and the bottom of the air bag 5 is close to the four third pressure sensors 83.

[0037] During the hard impact test, the impact plate 43 is in close contact with the support plate 42 on the lifting plate 41. When the impact block hits the top of the bag body 9, the impact plate 43 transfers the impact torque to the first pressure sensor 81 through the support plate 42. The second pressure sensor 82 directly monitors the impact torque, thereby tracking and monitoring the impact torque received by the filling inside the bag body 9 during the hard impact test. This facilitates the analysis of the impact resistance of the bag body 9 and the protection performance of the internal filling by the testing personnel during the hard impact test.

[0038] During the soft impact test, the air bag 5 continuously pushes the impact plate 43 upward away from the lifting plate 41 and the support plate 42. At the same time, the telescopic end of the second electrically controlled lifter 74 drives the damper 73 and the second pressure sensor 82 to move upward along with the limit slide and fixing frame 72 connected to the impact plate 43. Then, when the impact block hits the top of the bag body 9, the impact plate 43 will transfer part of the impact torque to the third pressure sensor 83 of the lifting plate 41 through the air bag 5. At the same time, the impact plate 43 will transfer another part of the impact torque to the second pressure sensor 83 through the limit slide 71 and the impact plate 43. 2 and the damper 73, the third pressure sensor 83 performs torque monitoring on the overall process of the air bag 5 absorbing and reducing the impact torque, and at the same time the second pressure sensor 82 performs torque monitoring on the overall process of the damper 73 absorbing and reducing the impact torque. After comprehensively analyzing the monitoring data of the second pressure sensor 82 and the third pressure sensor 83, it is possible to track and monitor the impact torque exerted on the internal filling of the bag body 9 during the soft impact test, so that the testing personnel can analyze the impact resistance of the bag body 9 and the protection performance of the internal filling during the soft impact test.

[0039] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
