[0016] (3) Beneficial effects Compared with the prior art, the present invention provides an impact testing device and a testing method for cosmetic pen performance testing, which have the following beneficial effects: 1. The impact testing device is provided with a base, a roller and a support plate. When the roller rotates, the support plate brings the cosmetic pen to a high place. As the height changes, the inclination angle of the support plate changes, so that the cosmetic pen can slide naturally when it moves to a high place. With the setting of the guide bucket and the impact plate, the cosmetic pen moved to a high place is guided by the guide bucket and hits a specific position on the surface of the impact plate, thereby completing the impact performance test of the cosmetic pen. At the same time, since the height of the impact plate can be adjusted by the height adjustment mechanism, it is convenient to test the probability of damage of the cosmetic pen after being impacted under conditions of different drop heights.

[0017] 2. The impact test device is equipped with a collection box and a flipping mechanism, which makes it easy to move the collection box after the test is completed to collect the makeup brushes that have fallen into the guide bucket and the debris generated by the impact. This reduces the difficulty of removing debris from the drum and the time required to remove the makeup brushes, thereby improving test efficiency.

[0018] 3. This impact testing device enables the support plate to rotate by providing a rotating rod, a gear ring, and a transmission gear. Therefore, the end of the support plate away from the rotating rod can also be in contact with the inner wall of the drum, so that when the drum rotates, the cosmetic brush moves through friction. When the cosmetic brush moves to a certain height, it slides down along the side wall of the support plate and the inner wall of the drum, thereby testing the impact resistance of the cosmetic brush when it is dropped from a low height.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] For specific embodiment 1, please refer to Figure 1 、 Figure 2 and Figure 5 The present invention provides an impact testing device, comprising a base 1 and a drum 2, wherein the drum 2 is rotatably arranged above the base 1, and an assembly door 21 and an entry door 22 are respectively provided on both sides of the drum 2, a support frame 11 is fixedly mounted on the assembly door 21, the support frame 11 is slidably connected to the base 1, and the entry door 22 is hingedly mounted on the outer wall of the drum 2; The drum 2 is provided with a supporting plate 3 which is arranged in a circular array inside the drum 2 and is used to transport the cosmetic brushes that fall into the drum 2 to a higher place and make the cosmetic brushes fall down when they reach a higher place. The assembly door 21 is provided with a guide bucket 4 and a striker plate 5. The guide bucket 4 is fixedly connected to the assembly door 21 and is used to receive the cosmetic brushes that fall from the support plate 3 and discharge them from the outlet of the guide bucket 4. The striker plate 5 is provided below the outlet of the guide bucket 4. The assembly door 21 is also provided with a height adjustment mechanism 7 for adjusting the height of the striker plate 5. A collection box 6 is also provided on the assembly door 21. When performing an impact test, the collection box 6 is kept away from the position between the outlet of the guide bucket 4 and the impact plate 5 to avoid hindering the makeup pencils from colliding with the impact plate 5. After the impact test is completed, the collection box 6 moves to the bottom of the outlet of the guide bucket 4 to collect the makeup pencils.

[0023] As can be seen from the above, the impact testing device is provided with a base 1, a roller 2 and a support plate 3. When the roller 2 rotates, the support plate 3 brings the cosmetic pencil to a high place, and as the height changes, the inclination angle of the support plate 3 changes, so that the cosmetic pencil can slide naturally when it moves to a high place. With the setting of the guide bucket 4 and the impact plate 5, the cosmetic pencil moved to a high place falls into the guide bucket 4 and is guided by the guide bucket 4 to hit a specific position on the surface of the impact plate 5, thereby completing the test of the impact performance of the cosmetic pencil. The cosmetic pencil hitting the impact plate 5 will slide off the impact plate 5, contact the inner wall of the roller 2 again, and be transported upward by the support plate 3, so that the cosmetic pencil placed in the roller 2 can be impact tested multiple times. At the same time, since the height adjustment mechanism 7 can adjust the height of the impact plate 5, it is convenient to test the damage probability of the cosmetic pencil after being impacted under conditions of different drop heights. At the same time, by providing a collection box 6, after the test is completed, the collection box 6 is moved to the bottom of the outlet of the guide bucket 4. Thereafter, the cosmetic pencils discharged from the outlet of the guide bucket 4 can directly fall into the collection box 6, and there is no need to manually collect the cosmetic pencils.

[0024] When using the impact testing device, the height of the impact plate 5 is adjusted using the height adjustment mechanism 7 so that the drop height of the cosmetic pencils is equal to the height to which the cosmetic pencils fall when they fall from the supporting plate 3 to contact the impact plate 5; the cosmetic pencils to be tested are placed in batches into the interior of the drum 2, and the assembly door 21 and the access door 22 are closed. The drum 2 is then controlled to rotate and the impact test is started. After the impact test is completed, the collection box 6 is moved to the bottom of the guide bucket 4 to collect the cosmetic pencils. After the cosmetic pencils are collected, the drum 2 is controlled to stop rotating, and the access door 22 is opened to take out the collection box 6. The cosmetic pencils in the collection box 6 are poured out for inspection; and the collection box 6 is put back into the interior of the drum 2.

[0025] Specific embodiment 2, as Figure 2 、 Figure 5 、 Figure 8 and Figure 9As shown, the difference between this embodiment and the above embodiment is that the height adjustment mechanism 7 includes a threaded rod 71, a threaded slider 72 and an adjusting rod 73. Both ends of the threaded rod 71 are rotatably mounted with a rotating mounting block 74, which is fixedly connected to the surface of the assembled door 21, the threaded slider 72 is fixedly connected to the striker 5, and the threaded slider 72 is threadedly connected to the threaded rod 71. A sliding groove 75 is provided on the surface of the threaded slider 72, and a guide bar 76 is fixedly mounted on the surface of the assembled door 21. The guide bar 76 is slidably connected to the sliding groove 75, and the adjusting rod 73 is rotatably connected to the assembled door 21. The end of the adjusting rod 73 extending to the interior of the drum 2 is fixedly mounted with a driving bevel gear 77, and the upper end of the threaded rod 71 is fixedly mounted with a driven bevel gear 78, which is meshed with the driving bevel gear 77. A height adjustment control motor 79 is fixedly mounted on the support frame 11, and the driving end of the height adjustment control motor 79 is fixedly connected to the other end of the adjusting rod 73.

[0026] As can be seen from the above, since the guide bar 76 is slidably connected to the slide groove 75, the threaded slider 72 can only move linearly along the length direction of the guide bar 76. Therefore, the threaded slider 72 threadedly connected to the threaded rod 71 changes height when the threaded rod 71 rotates, thereby driving the striker 5 fixedly connected to the threaded slider 72 to move up and down. Since the driven bevel gear 78 is meshed with the active bevel gear 77, the adjustment rod 73 drives the threaded rod 71 to rotate when it rotates. At the same time, since the height adjustment control motor 79 and the assembly door 21 are both fixedly mounted on the support frame 11, when the height adjustment control motor 79 is working, it drives the striker 5 to move up and down through the adjustment rod 73 and the threaded rod 71.

[0027] A support seat 12 is fixedly installed on the base 1, and a guide rod 121, a screw rod 122 and a threaded slide 123 are provided inside the support seat 12. The two ends of the guide rod 121 are fixedly connected to the support seat 12, and the two ends of the screw rod 122 are rotatably connected to the support seat 12. The threaded slide 123 is slidingly connected to the guide rod 121, and the threaded slide 123 is threadedly connected to the screw rod 122. The upper end of the threaded slide 123 is fixedly connected to the lower end of the support frame 11. A translation drive motor 13 is fixedly installed on the support seat 12, and the driving end of the translation drive motor 13 is fixedly connected to one end of the screw rod 122.

[0028] As can be seen from the above, when the translation drive motor 13 drives the screw rod 122 to rotate, the threaded slide 123 translates accordingly, driving the support frame 11 to slide horizontally, thereby realizing the assembly door 21 approaching or moving away from the side opening of the drum 2. In the present application, one of the functions of the assembly door 21 is to prevent the makeup brushes and the generated fragments from falling from the side opening of the drum 2 during the impact test. Therefore, the assembly door 21 does not need to be tightly connected to the drum 2. However, an annular connecting ring can also be rotatably installed on the outer edge of the assembly door 21 to make the connecting ring fit tightly with the side opening of the drum 2 during the impact test, thereby reducing the probability of fragments falling out.

[0029] A support shaft 14 is rotatably installed on the inner side of the base 1, and a roller 15 is fixedly installed on the support shaft 14. Rolling plates 26 are fixedly installed at both ends of the drum 2, and the rolling plates 26 are rotatably installed between the rollers 15. A rolling drive motor 16 is also fixedly installed inside the base 1, and the rolling drive motor 16 is transmission-connected to one of the support shafts 14.

[0030] As can be seen from the above, due to the setting of the rolling drive motor 16, the support shaft 14 and the rolling disk 26, when the assembly door 21 slides horizontally away from the drum 2, the drum 2 can be directly lifted and removed from the base 1. That is to say, the drum 2 in this application also has the characteristic of being easy to disassemble and replace.

[0031] Specific embodiment three, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the difference between this embodiment and the above embodiment is that a flip mechanism 8 is provided on the assembly door 21, and the flip mechanism 8 includes a rotating plate 81, a rotating shaft 82 and a sliding shaft 83. A slot 84 is provided on the surface of the rotating plate 81, and plug blocks 61 are fixedly installed at both ends of the collection box 6. The plug blocks 61 are adapted to be plugged into the slots 84. The rotating shaft 82 and the sliding shaft 83 are respectively fixedly installed at both ends of the rotating plate 81, and the other end of the rotating shaft 82 is rotatably connected to the assembly door 21. An arc-shaped through groove 85 with the axis of the rotating shaft 82 as the arc center is provided on the assembly door 21, and the other end of the sliding shaft 83 is slidably installed inside the arc-shaped through groove 85.

[0032] As can be seen from the above, when the sliding shaft 83 rotates to the other end of the arc-shaped through groove 85, the rotating plate 81 is completely moved to one side of the guide bucket 4, and will not hinder the cosmetic pencils from falling from the guide bucket 4 and contacting the impact plate 5. At the same time, after the impact test is completed, the collection box 6 can be directly moved to collect the cosmetic pencils. In addition, by providing the slot 84 and the insert block 61, it is convenient to disassemble and assemble the collection box 6. Therefore, after the impact test is completed, it is only necessary to push the sliding shaft 83 to move to collect the cosmetic pencils, and the collection box 6 can be quickly taken out by opening the access door 22.

[0033] The flipping mechanism 8 also includes an arc-shaped socket 86 and a nut 87. The arc-shaped socket 86 is arranged at both ends of the arc-shaped through groove 85, and the arc-shaped socket 86 is fixedly connected to the assembly door 21. One end of the sliding shaft 83 is provided with a thread. The nut 87 is threadedly connected to the sliding shaft 83, and one end of the nut 87 is coaxially fixed with a plug 88. The plug 88 is adapted to be plugged into the arc-shaped socket 86. A stopper 89 is also fixedly installed at the end of the sliding shaft 83. The diameter of the stopper 89 is larger than the aperture of the nut 87.

[0034] As can be seen from the above, since one end of the sliding shaft 83 is provided with a thread, the insert 88 fixedly mounted on the nut 87 can move horizontally when the nut 87 rotates, so that the insert 88 can be inserted into the interior of the arc-shaped sleeve 86 and is not easy to fall out. Therefore, the sliding shaft 83 can be quickly fixed to one end of the arc-shaped through groove 85.

[0035] Specific embodiment four, as Figure 3 and Figure 6 As shown, the difference between this embodiment and the above embodiment is that a rotating rod 31 is fixedly installed at one end of the support plate 3, both ends of the rotating rod 31 are rotatably connected to the inner wall of the drum 2, one end of the rotating rod 31 is fixedly connected to a transmission gear 32, and a gear ring 23 is rotatably installed on the outside of the drum 2, and the gear ring 23 is meshed with the transmission gear 32.

[0036] As can be seen from the above, by providing the rotating rod 31 , the transmission gear 32 and the gear ring 23 , when the gear ring 23 rotates, the rotating rod 31 drives the supporting plate 3 to rotate a certain angle.

[0037] The gear ring 23 is provided with arc-shaped sliding holes 24 distributed in a ring array. A limit rod 25 is slidably installed inside the arc-shaped sliding hole 24. The limit rod 25 is fixedly connected to the outer surface of the drum 2.

[0038] As can be seen from the above, by providing the arc-shaped sliding hole 24 and the limiting rod 25 , the rotation angle of the gear ring 23 is limited.

[0039] An extension block 27 is fixedly mounted on the gear ring 23, an insertion rod 28 is inserted into the extension block 27, a return spring 29 is fixedly connected between the head of the insertion rod 28 and the extension block 27, and a limiting groove 210 is provided on the drum 2, which is engaged with the return spring 29.

[0040] As can be seen from the above, by setting the extension block 27, the insertion rod 28 and the limiting groove 210, when the insertion rod 28 is inserted into the limiting groove 210, the gear ring 23 cannot rotate relative to the drum 2, so the rotating rod 31 and the support plate 3 are also fixed on the drum 2.

[0041] Specific embodiment five, as Figure 6As shown, the difference between this embodiment and the above embodiment is that the upper surface of the collision plate 5 is set as an inclined surface, and an impact force sensor 51 is installed on the collision plate 5.

[0042] As can be seen from the above, since the upper surface of the striker plate 5 is set as an inclined surface, the cosmetic brushes that fall onto the upper surface of the striker plate 5 can slide to the side of the striker plate 5 that is inclined downward, so that the fallen cosmetic brushes can enter between the adjacent supporting plates 3 in sequence. By setting up an impact force sensor 51, the impact force generated when the cosmetic brush collides with the striker plate 5 can be detected. Since the striker plate 5 is installed on the assembly door 21, and the assembly door 21 is slidably installed on the base 1, the striker plate 5 will not move as the drum 2 rotates. Therefore, the impact force sensor 51 will not be disturbed by the centrifugal force generated by the rotation of the drum 2. Specifically, in this embodiment, a notch is opened in the middle of the striker plate 5, and a material that is slidably installed inside the notch is connected to the upper surface of the striker plate 5. The pressure block has a smooth transition surface, and the impact force sensor 51 is fixedly installed under the impact plate 5 through a connecting piece, and the pressure sensing end of the impact force sensor 51 is connected to the pressure block. When the makeup pen falls, it hits the pressure block, and the impact force is transmitted to the impact force sensor 51. According to the momentum theorem, when an object falls from the same height, the greater the mass, the greater the impact force. Therefore, by setting the impact force sensor 51, it is possible to determine whether the mass of the makeup pen changes during the test. Therefore, the height of the impact plate 5 can be gradually lowered in a test, and the impact force sensor 51 can be used to detect the increase in the falling height of the makeup pen when it breaks, which can more conveniently determine the impact resistance of the makeup pen.

[0043] For specific embodiment six, please refer to Figure 1 - Figure 9 The present invention also discloses a test method for cosmetic pen performance testing, which comprises the following steps: Use the height adjustment mechanism 7 to adjust the height of the impact plate 5 so that the drop height of the cosmetic brush is equal to the height the cosmetic brush drops when it falls from the support plate 3 to the impact plate 5; Put the cosmetic brushes to be tested in batches into the drum 2, close the assembly door 21 and the access door 22, and then control the drum 2 to rotate and start the impact test; After the impact test is completed, the collection box 6 is moved to the bottom of the guide bucket 4 to collect the makeup brushes. After the makeup brushes are collected, the drum 2 is controlled to stop rotating, and then the access door 22 is opened to take out the collection box 6, and the makeup brushes in the collection box 6 are poured out for inspection; And put the collecting box 6 back into the interior of the drum 2.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
