Description

Technical Field

[0001] The present invention relates to the technical field of impact resistance testing, in particular to an impact resistance testing device for cosmetic bottle production. Background Art

[0002] In the cosmetics production industry, cosmetic bottles are important packaging containers for cosmetics. Their quality directly affects the safety of cosmetics during transportation, storage and use. In the actual circulation process, cosmetic bottles may be subjected to impacts from various directions and different intensities. Therefore, impact resistance testing of cosmetic bottles has become a key link in ensuring product quality.

[0003] Currently, there are deficiencies in the impact resistance test equipment for cosmetics. For example, when simulating a cosmetic bottle being dropped to the ground by an external force during use (the cosmetic bottle is placed on a dressing table and accidentally swept to the ground by the user), it is very likely that the cosmetic bottle will not break when it hits the ground for the first time, and then break when it bounces and falls to the ground again. Such a situation may also occur during the actual test. However, the execution standard of the impact resistance test of the cosmetic bottle is usually to test the impact of the cosmetic bottle when it first falls to the ground. The second fall of the cosmetic bottle will affect the test and affect the results of the impact resistance test of the cosmetic bottle. Summary of the Invention

[0018] Reference Figure 1-Figure 5The present invention proposes an impact resistance test device for cosmetic bottle production, comprising a base box 1, a lifting rod 2 installed on the base box 1, and a supporting plate 3 installed on the output shaft of the lifting rod 2. Under normal circumstances, the supporting plate 3 is in a horizontal state, and a force-applying member 4 and a constant power mechanism for driving the force-applying member 4 to slide on the supporting plate 3 are slidably installed on the supporting plate 3. When the cosmetic bottle impact resistance test is carried out, the constant power mechanism drives the force-applying member 4 to slide on the supporting plate 3, controls the force applied by the force-applying member 4 on the cosmetic bottle and the initial movement speed (when the cosmetic bottle is knocked off the dressing table, it is mostly caused by the user's arm swinging, and the different swing amplitude and swing strength of the arm lead to different forces and initial speeds of the cosmetic bottle). The constant power mechanism drives the movement of the force-applying member 4 with a constant driving force, which can To achieve better control and reduce errors in test results, the top surface of the base box 1 is provided with a slot 5, within which a catch strip 6 is installed. A floor panel 7 is slidably mounted on the top surface of the base box 1. The material of floor panel 7 is determined based on test requirements. Floor panel 7 can block the top opening of slot 5. When a cosmetic bottle is dropped onto floor panel 7 for the first time, floor panel 7 slides and opens the top opening of slot 5, allowing the cosmetic bottle to fall onto catch strip 6. During the specific test, if the cosmetic bottle bounces after falling onto floor panel 7, floor panel 7 slides, and the bounced bottle will fall onto catch strip 6 in slot 5 during the second drop. This reduces the risk of the cosmetic bottle breaking after a second drop and reduces interference with the test results. Currently, only the results of the cosmetic bottle's first drop are tested (for example, ASTM D5486 and ISO 7876 specify that drop tests only focus on the "first impact" result, requiring the impact surface to be a rigid surface (such as a steel platform), but do not mandate control of the second bounce).

[0019] like Figure 1 and Figure 2 As shown in , a plurality of simulated ground blocks 8 are installed on the top surface of the ground panel 7, and the plurality of simulated ground blocks 8 are arranged in a matrix. Pressure sensors are installed on the simulated ground blocks 8, and the plurality of simulated ground blocks 8 are spliced ​​into a simulated ground. There is a small gap between two adjacent simulated ground blocks 8 to reduce the mutual interference of the simulated ground blocks 8 when they are subjected to force. The material of the simulated ground blocks 8 is set according to the test needs. The top view of the simulated ground block 8 is a square with a side length of unit length (for example, 1 cm). The ground formed by the plurality of simulated ground blocks 8 is regarded as a grid of multiple unit areas, and each simulated ground block 8 is regarded as a coordinate point, which is convenient for determining the coordinate position of the cosmetic bottle landing and reducing the error of the test. The pressure sensor detects the force applied when the cosmetic bottle impacts the simulated ground block 8.

[0020] like Figure 2 and Figure 3As shown in, the constant power mechanism includes a constant force spring 9, a limit slider 10, a mounting block 11 and a resistance adjustment assembly; a rotating groove is provided in the support plate 3, and the inner ring end of the constant force spring 9 is fixedly installed in the rotating groove. A linear groove connected to the rotating groove is also provided in the support plate 3, and the outer ring end of the constant force spring 9 is slidably set in the linear groove, and a limit slide groove connected to the linear groove is provided on the top surface of the support plate 3. The bottom end of the limit slider 10 is fixedly connected to the outer ring end of the constant force spring 9, the limit slider 10 is slidably installed in the limit slide groove, the mounting block 11 is fixedly installed on the top of the limit slider 10, and the force applying member 4 is fixedly installed on one side of the mounting block 11. The resistance adjustment assembly is used to adjust one The size of the resistance when the constant force spring 9 slides. When conducting a cosmetic bottle drop test, the cosmetic bottle is placed on the support plate 3, and the resistance adjustment component is used to control the size of the friction force of the constant force spring 9 sliding when winding, thereby controlling the size of the force applied to the cosmetic bottle. Due to the characteristics of the constant force spring 9, the force applied during winding and stretching is always consistent, and the size of the friction force is controlled to remain consistent, that is, the force applied to the force-applying member 4 to impact the cosmetic bottle remains unchanged, and then the length of the movement path of the force-applying member 4 is controlled to adjust the initial speed of the cosmetic bottle when it is impacted, and the limit slider 10, the mounting block 11 and the force-applying member 4 are synchronously accelerated and slid by the winding and pulling of the constant force spring 9.

[0021] like Figure 3 As shown in the figure, the resistance adjustment assembly includes a clamping block 12 and a pressure adjustment member; a movable groove connected to the linear groove is opened in the support plate 3, and the clamping block 12 is slidably installed in the movable groove. The clamping block 12 can be clamped on the No. 1 constant force spring 9, and the pressure adjustment member is used to adjust the pressure of the clamping block 12 against the No. 1 constant force spring 9. When adjusting the sliding resistance of the No. 1 constant force spring 9, the pressure adjustment member drives the clamping block 12 to press against the No. 1 constant force spring 9. The positive pressure is increased, thereby controlling the friction force.

[0022] like Figure 3 and Figure 5As shown in , the pressure regulating member includes a support frame 13, a force rod 14, a connecting rod 15 and a counterweight; the support frame 13 is fixedly mounted on the bottom surface of the supporting plate 3, the force rod 14 is rotatably mounted on the support frame 13, the force rod 14 is in a horizontal state in a normal state, one end of the connecting rod 15 is fixedly connected to the tightening block 12, and the other end of the connecting rod 15 slides through the supporting plate 3 and rests on the force rod 14, and the counterweight is used to drive the force rod 14 to rotate and rest on the end of the connecting rod 15 away from the tightening block 12, and the counterweight includes a stopper 16, a threaded rod 17 and a counterweight 18; the counterweight 18 The thickness is the same but the diameter is different. The position of the counterweight 18 is blocked by the blocking piece 16 to ensure that the key position of the counterweight 18 remains unchanged. The blocking piece 16 is fixedly connected to the end of the force rod 14, and the threaded rod 17 is fixedly connected to the blocking piece 16. The counterweight 18 is threadedly mounted on the threaded rod 17. In actual conditions, by replacing the weight of the counterweight 18, the force rod 14 is rotated and the lever principle is used to drive the force rod 14 to push the connecting rod 15 and the clamping block 12 to press against the No. 1 constant force spring 9. The friction force is controlled by a mechanical structure, and the structure is simple and the operation is convenient.

[0023] like Figure 2 As shown in the figure, a slow-release mechanism is also installed on the base box 1. When the cosmetic bottle falls onto the receiving cloth strip 6, the slow-release mechanism is used to release the receiving cloth strip 6 and make the receiving cloth strip 6 move downward to buffer the force of the cosmetic bottle falling. The slow-release mechanism includes a No. 2 constant-force spring 19. A release groove is provided in the base box 1. The inner ring end of the No. 2 constant-force spring 19 is fixedly installed in the release groove. The outer ring end of the No. 2 constant-force spring 19 is fixedly connected to one end of the receiving cloth strip 6. In actual conditions, the cosmetic bottle falls on the receiving cloth strip 6 when it bounces off the ground for the first time. Due to the elasticity of the receiving cloth strip 6 The spring may also cause the cosmetic bottle to bounce up again, so a second constant-force clockwork spring 19 is set. When the cosmetic bottle falls on the receiving cloth strip 6, the receiving cloth strip 6 tends to move downward, and the receiving cloth strip 6 pulls the second constant-force clockwork spring 19, causing the cosmetic bottle to fall on the receiving cloth strip 6 and slowly descend, reducing the situation of bouncing up again. Due to the characteristics of the second constant-force clockwork spring 19, when the cosmetic bottle falls and is pulled and released, the reaction force of the second constant-force clockwork spring 19 cannot drive the receiving cloth strip 6 to lift the cosmetic bottle, reducing the interference caused by the secondary collision of the cosmetic bottle bouncing up to the test.

[0024] like Figure 1The locking nut 21 is threadedly fitted on the half-threaded rod and can be tightened against the output shaft of the lifting rod 2. In actual operation, the projection angle of the cosmetic bottle may be different when it is collided and flew out. By adjusting the rotation inclination angle of the rotation shaft rod 20, the angle of projection of the cosmetic bottle can be ensured. By rotating the inclination angle of the supporting plate 3 and the rotation angle of the rotation shaft rod 20 on the output shaft of the lifting rod 2, and then tightening the locking nut 21 to fix the position of the rotation shaft rod 20, the initial projection angle of the cosmetic bottle when it is collided can be adjusted, which better simulates the test environment.
