Description

Technical Field

[0001] This invention relates to the field of cosmetic production technology, and more specifically, to a cosmetic packaging airtightness testing system. Background Technology

[0002] Cosmetic packaging refers to containers for cosmetics, as well as secondary packaging for fragrances and cosmetics. Cosmetics are substances used to cleanse, beautify, and enhance the appearance of the human body without altering its structure or function. The primary purpose of cosmetic containers is to protect the product during storage or transportation, and the containers must be well-thought-out solutions that prevent product deterioration and help maintain its quality. As part of beauty product marketing, they must be aesthetically pleasing containers. Therefore, for cosmetics such as foundation, airtightness testing is particularly important to prevent deterioration.

[0003] According to Chinese Patent No. CN208579885U, the upper surface of the sealing cover is equipped with a vacuum pump and a pressure gauge that communicate with the sealing cavity. A support frame is provided on one side of the worktable, and a lead screw is provided on the inner side of the support frame. The lead screw is driven by a motor located on the top of the support frame. A slider that cooperates with the lead screw is connected to one side of the sealing cover. The detection device is suitable for detecting products with tubular packaging. This device can detect whether there is leakage without damaging the packaging and can completely replace the existing manual detection and costly detection methods.

[0004] However, when implementing the above solution, it is necessary to clamp cosmetic packaging products with the same pipe diameter using a vacuum pump and pressure gauge. The cost of testing cosmetic bottles with different diameters is high. Furthermore, due to the unequal installation, air leakage inside the vacuum pump leads to inaccurate test data. Therefore, we propose a cosmetic packaging airtightness testing system. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a cosmetic packaging airtightness testing system. The system utilizes a first gear meshing with a second long rod to rotate the second long rod. The second long rod is driven to rotate via a threaded connection between an internal threaded rod and an external threaded rod, causing the external threaded rod to move upwards or downwards through a positioning connecting rod. As the external threaded rod drives the positioning connecting rod downwards, the positioning connecting rod moves the testing frame closer to the cosmetic bottle below to test its internal airtightness, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cosmetic packaging airtightness testing system, comprising a processing frame, a support base fixedly connected to the bottom end of the processing frame, and a forward and reverse motor fixedly connected to one end of the processing frame. Two sets of main clamping frames are fixedly connected to the upper and lower ends of the forward and reverse motor. A first hinge rod is hinged between the two sets of main clamping frames. A second hinge rod is hinged to one end of the first hinge rod. Slide grooves are provided at both ends of the second hinge rod. An auxiliary clamping block is slidably connected inside the second hinge rod through the slide groove. A positioning block is fixedly connected to one end of the auxiliary clamping block. A wrapping positioning frame is fixedly connected to the outer surface of the positioning block. An auxiliary spring is fixedly connected to one end of the second hinge rod. One end of the auxiliary spring is fixedly connected to the surface of the positioning block. Two sets of fixed circular blocks are fixedly connected to one end of the positioning block. A bent rod is hinged to the outer surface of the two sets of fixed circular blocks. An internal threaded rod is rotatably connected to one end of the bent rod. A first gear is fixedly connected to the bottom end of the internal threaded rod. An external threaded rod is connected to the inside of the internal threaded rod through a thread. There are two sets of internal threaded rods. A long rod is fixedly connected between the two sets of internal threaded rods. A positioning connecting rod is fixedly connected to one end of the external threaded rod. A detection frame is fixedly connected to the bottom end of the positioning connecting rod. A forward and reverse motor is used as the drive. The forward and reverse motor drives the main rod to rotate. The main rod rotates along the clamping of the bidirectional clamping block. The main rod drives the first gear to rotate. The first gear meshes with the second long rod, causing the second long rod to rotate. The second long rod transmits through the thread between the internal threaded rod and the external threaded rod, causing the external threaded rod to move up or down through the limit of the positioning connecting rod.

[0007] In a preferred embodiment, the bottom end of the testing frame is fixedly connected to an inclined insert with an internal cavity. A buffer pad is fixedly connected to the inner wall of the inclined insert. One end of the buffer pad is inserted into a limiting insert. The limiting insert is fixedly installed at the end of the inclined insert near the testing frame. As the testing frame is inserted into the cosmetic bottle, the inclined surface of the inclined insert is inserted along the diameter of the cosmetic bottle opening. During the insertion process, according to the inner diameter of the cosmetic bottle, the side wall of the inclined insert is lubricated, causing the inner wall of the inclined insert to drive the buffer pad to slide along the outer surface of the limiting insert, causing the inclined insert to be restricted by the limiting insert and form a regular contraction.

[0008] In a preferred embodiment, a ferrous hydroxide placement rack is fixedly connected to the inner wall of the testing frame, a disposable insulating paper cover is fixedly connected to the bottom end of the testing frame, and a vacuum pump is fixedly connected to the end of the testing frame away from the inclined insertion block. The positioning connecting rod drives the testing frame to be inserted into the cosmetic bottle. Due to the surface of the testing frame being squeezed and bent, the disposable insulating paper cover is crushed. At this time, the testing frame and the inside of the cosmetic bottle are in a sealed state. The vacuum pump on the surface of the testing frame evacuates the air at the connection between the two through the tube inserted into the testing frame.

[0009] In a preferred embodiment, one end of the forward and reverse motor is fixedly connected to a main rod, and two sets of bidirectional clamping blocks are attached to the outer surface of the main rod. Two sets of third hinge rods are hinged to the upper and lower ends of the bidirectional clamping blocks. One end of each set of third hinge rods is hinged to the outer surface of the positioning block. The bidirectional clamping block improves its stability by deflecting on the surface of the positioning block using the third hinge rods, making it less prone to shaking.

[0010] In a preferred embodiment, the outer surface of the package positioning frame is provided with a set of through sliding grooves, and a plugging block is slidably connected inside the sliding groove. An auxiliary spring rod is slidably connected to the bottom end of the plugging block, and a corresponding clamping block is hinged to one end of the plugging block.

[0011] In a preferred embodiment, the corresponding clamping blocks are arranged in two sets, with the two sets of corresponding clamping blocks arranged in a cross configuration. The package positioning frames are arranged in multiple sets, and the distance between each pair of package positioning frames is adjusted by the cross-bending of the corresponding clamping blocks. The package positioning frames rely on the pushing force transmitted from the auxiliary clamping blocks to the positioning blocks to adjust the distance between the two sets of package positioning frames. The two sets of corresponding clamping blocks are bent to adjust the distance between them. The two sets of interlocking blocks house the auxiliary spring rod, and the spring on the surface of the auxiliary spring rod limits and restores the distance between the two sets of interlocking blocks.

[0012] In a preferred embodiment, a hollow mounting frame is fixedly connected inside the packaging positioning frame. Multiple sets of bidirectional hollow clamping blocks are fixedly connected to the inner wall of the hollow mounting frame. Multiple sets of spring packaging frames are slidably connected between every two sets of bidirectional hollow clamping blocks. The operator manually inserts the cosmetic bottle into the inner wall of the spring packaging frame. For aesthetic purposes and ease of handling, some cosmetic bottles have decorative decorations on their packaging surface. These decorations contact the arc-shaped surface of the inner cavity insertion rod. Due to the gap between the spring packaging frame and the inner cavity insertion rod, these protruding decorations can be inserted into the groove created by the gap. The flatter part of the cosmetic bottle contacts the inner wall of the inner cavity insertion rod, thus clamping the cosmetic bottle.

[0013] In a preferred embodiment, multiple sets of spring wrappers are slidably connected by connecting ropes. The spring wrappers are in a contracted or expanded state along the surface of the connecting ropes due to the compression of cosmetic bottles. The inner cavity insert rod is compressed by cosmetic bottles of different diameters, causing the spring wrappers to slide along the outer surface of the connecting ropes. During the sliding process, the spring wrappers are clamped and limited by bidirectional hollow clamps, causing the spring wrappers to perform telescopic movements within the diameter of the bidirectional hollow clamps.

[0014] In a preferred embodiment, an inner cavity insert rod is fixedly connected inside the spring wrapping frame, and a circular limiting rubber push cavity wall is fixedly connected to the inner wall of the inner cavity insert rod.

[0015] In a preferred embodiment, a buffer rubber frame is fixedly connected to the inner wall of the inner cavity insert rod. A double hollow insert rod with an internal cavity is fixedly connected inside the buffer rubber frame. The outer wall of the inner ring cavity wall is in contact with the outer wall of the limiting rubber push cavity wall. When the outer wall of the inner cavity insert rod is squeezed, the inner cavity insert rod transmits the pressure to the double hollow insert rod through the buffer rubber frame. The double hollow insert rod is compressed, causing the inner ring cavity wall to expand outward. The inner ring cavity wall expands outward by squeezing the limiting rubber push cavity wall. The inner cavity insert rod relies on the bending pressure transmitted by the limiting rubber push cavity wall to firmly grip the surface of the cosmetic bottle, thereby improving the stability of cosmetic bottle detection.

[0016] The technical effects and advantages of this invention are as follows: 1. The first gear meshes with the second long rod, causing the second long rod to rotate. The second long rod transmits power through the thread between the internal threaded rod and the external threaded rod, causing the external threaded rod to move up or down through the limit of the positioning connecting rod. As the external threaded rod drives the positioning connecting rod to descend, the positioning connecting rod drives the detection frame to approach the cosmetic bottle below to detect its internal airtightness, thereby improving the overall detection efficiency and facilitating the realization of an integrated workflow. 2. The auxiliary spring rod is stored between the two sets of interlocking blocks, and the spring on the surface of the auxiliary spring rod limits and restores the distance between the two sets of interlocking blocks. When the two sets of corresponding clamping blocks bend, the interlocking blocks are subjected to a reaction force and slide along the inner cavity of the sliding groove until the distance between the positioning frame is adjusted to the specified state, which facilitates the clamping of cosmetic bottles of different heights, thereby expanding the clamping range of cosmetic bottles of different heights and realizing the diversity of cosmetic bottle installation. 3. When the outer wall of the inner cavity insert is squeezed, the inner cavity insert transmits the pressure to the double hollow insert through the buffer rubber frame. The double hollow insert is compressed, causing the inner ring cavity wall to expand outward. The inner ring cavity wall is pushed outward by the squeezing limiting rubber. The inner cavity insert relies on the bending pressure transmitted by the limiting rubber to tightly grip the surface of the cosmetic bottle, thereby improving the stability of cosmetic bottle detection. 4. As the testing frame is inserted into the cosmetic bottle, the inclined surface of the tilted insert is inserted along the bottle's opening diameter. During insertion, the sidewall of the tilted insert is lubricated according to the bottle's internal diameter, causing the inner wall of the tilted insert to slide along the outer surface of the limiting insert. This results in the tilted insert being restricted by the limiting insert and forming a regular contraction, allowing the entire tilted insert to be inserted into the cosmetic bottle. This enables sealing testing of cosmetic bottles of different diameters, reducing testing costs. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Refer to the instruction manual appendix Figure 1-10 An embodiment of the present invention provides a cosmetic packaging airtightness testing system, comprising a processing frame 1, a support base 2 fixedly connected to the bottom end of the processing frame 1, and a forward and reverse motor 3 fixedly connected to one end of the processing frame 1. Two sets of main clamping frames 4 are fixedly connected to the upper and lower ends of the forward and reverse motor 3. A first hinge rod 6 is hinged between the two sets of main clamping frames 4. A second hinge rod 10 is hinged to one end of the first hinge rod 6. Slide grooves 11 are provided at both ends of the second hinge rod 10. An auxiliary clamping block 18 is slidably connected inside the second hinge rod 10 through the slide groove 11. A positioning block 13 is fixedly connected to one end of the auxiliary clamping block 18. A wrapping positioning frame 5 is fixedly connected to the outer surface of the positioning block 13. An auxiliary spring 15 is fixedly connected to one end of the second hinge rod 10. One end of the auxiliary spring 15 is fixedly connected to the surface of the positioning block 13. Two sets of fixing round blocks 25 are fixedly connected to one end of the positioning block 13. A bent rod 19 is hinged to the outer surface of the two sets of fixing round blocks 25. One end of the bent rod 19 is rotatably connected to an internal threaded rod 26. A first gear 22 is fixedly connected to the bottom end of the internal threaded rod 26. An external threaded rod 21 is threadedly connected inside the internal threaded rod 26. There are two sets of internal threaded rods 26. A long rod 23 is fixedly connected between the two sets of internal threaded rods 26. A positioning connecting rod 35 is fixedly connected to one end of the external threaded rod 21. A detection device is fixedly connected to the bottom end of the positioning connecting rod 35. The frame 36 is driven by a forward and reverse motor 3, which rotates the main rod 8. The main rod 8 rotates under the clamping of the bidirectional clamping block 12. The main rod 8 drives the first gear 22 to rotate. The first gear 22 meshes with the second long rod 24, which in turn drives the second long rod 24 to rotate. The second long rod 24 transmits power through the thread between the internal threaded rod 26 and the external threaded rod 21, causing the external threaded rod 21 to move up or down through the limiting position of the positioning connecting rod 35. As the external threaded rod 21 drives the positioning connecting rod 35 to descend, the positioning connecting rod 35 drives the detection frame 36 to move closer to the cosmetic bottle below to detect its internal airtightness, thereby improving the overall detection efficiency and facilitating an integrated workflow.

[0030] Furthermore, the bottom end of the testing frame 36 is fixedly connected to an inclined insert 37 with an internal cavity. A buffer pad 38 is fixedly connected to the inner wall of the inclined insert 37. One end of the buffer pad 38 is inserted into a limiting insert 39, which is fixedly installed at the end of the inclined insert 37 near the testing frame 36. As the testing frame 36 is inserted into the cosmetic bottle, the inclined surface of the inclined insert 37 is inserted along the diameter of the cosmetic bottle. During the insertion process, the side wall of the inclined insert 37 is lubricated according to the inner diameter of the cosmetic bottle, causing the inner wall of the inclined insert 37 to drive the buffer pad 38 to slide along the outer surface of the limiting insert 39. This causes the inclined insert 37 to be restricted by the limiting insert 39 and to form a regular contraction, so that the entire inclined insert 37 is inserted into the cosmetic bottle. This achieves the sealing test of cosmetic bottles of different diameters and reduces the testing cost.

[0031] Refer to the instruction manual appendix Figure 10 The inner wall of the testing frame 36 is fixedly connected to a ferrous hydroxide holder, and the bottom of the testing frame 36 is fixedly connected to a disposable insulating paper cover. A vacuum pump is fixedly connected to the end of the testing frame 36 away from the inclined insert block 37. The positioning connecting rod 35 drives the testing frame 36 to be inserted into the cosmetic bottle. Due to the pressure and bending of the surface of the testing frame 36, the disposable insulating paper cover is crushed. At this time, the testing frame 36 and the inside of the cosmetic bottle are in a sealed state. The vacuum pump on the surface of the testing frame 36 evacuates the air at the connection between the two through the tube inserted into the testing frame 36. If there is still air leakage inside the cosmetic bottle, it reacts with the ferrous hydroxide in the ferrous hydroxide holder. Ferrous hydroxide is a white precipitate in an air-isolated environment. Upon contact with oxygen, it first turns grayish-green, then turns into a reddish-brown precipitate, forming ferric hydroxide. The reaction is extremely rapid. Ferrous hydroxide can be dissolved by adding hydrochloric acid or dilute sulfuric acid first. Nitric acid cannot be used to dissolve ferric hydroxide. Then, excess iron powder is added. After the reaction is complete, sodium hydroxide is added to reconstitute it into ferrous hydroxide. It must be carried out in an air-isolated area, which allows staff to quickly detect whether the cosmetic bottle is leaking. The operation is relatively simple.

[0032] Refer to the instruction manual appendix Figure 1-5 One end of the forward and reverse motor 3 is fixedly connected to the main rod 8. Two sets of bidirectional clamping blocks 12 are attached to the outer surface of the main rod 8. Two sets of third hinge rods 14 are hinged to the upper and lower ends of the bidirectional clamping blocks 12. One end of the two sets of third hinge rods 14 is hinged to the outer surface of the positioning block 13. The bidirectional clamping blocks 12 are improved in stability by deflecting on the surface of the positioning block 13 with the third hinge rods 14, and are not easy to shake. A set of through sliding grooves 9 are opened on the outer surface of the positioning frame 5. The sliding grooves 9 are slidably connected to the inside of the sliding grooves 9. The bottom end of the sliding block 16 is slidably connected to the auxiliary spring rod 17. One end of the sliding block 16 is hinged to the corresponding clamping block 7. Furthermore, there are two sets of corresponding clamping blocks 7, which are arranged in a cross configuration. There are multiple sets of package positioning frames 5. The distance between each pair of package positioning frames 5 is adjusted by the cross-bending of the corresponding clamping blocks 7. The package positioning frames 5 rely on the pushing force transmitted from the auxiliary clamping block 18 to the positioning block 13, causing the distance between the two sets of package positioning frames 5 to be adjusted. The two sets of corresponding clamping blocks 7 are bent to adjust the distance between them. The two sets of interlocking blocks 16 house the auxiliary spring rod 17. The surface spring limits and restores the distance between the two sets of interlocking blocks 16. When the two sets of corresponding clamping blocks 7 bend, the interlocking blocks 16 are subjected to a reaction force and slide along the inner cavity of the sliding groove 9 until the distance between the wrapping positioning frames 5 is adjusted to the specified state, which is convenient for clamping cosmetic bottles of different heights. If the cosmetic bottle is tall, two sets of wrapping positioning frames 5 can be selected to clamp one set of cosmetic bottles. If the cosmetic bottle is short, one set of wrapping positioning frames 5 can be selected to clamp one set of cosmetic bottles, thereby expanding the clamping range for cosmetic bottles of different heights and realizing the diversity of cosmetic bottle installation.

[0033] Refer to the instruction manual appendix Figure 1-6 The packaging positioning frame 5 is internally fixedly connected to a hollow placement frame 20. The inner wall of the hollow placement frame 20 is fixedly connected to multiple sets of bidirectional hollow clamping blocks 27. Multiple sets of spring packaging frames 28 are slidably connected between every two sets of bidirectional hollow clamping blocks 27. The staff manually inserts the cosmetic bottle into the inner wall of the spring packaging frame 28. For aesthetic purposes and ease of handling, some cosmetic bottles have decorations on their packaging surface. These decorations contact the arc-shaped surface of the inner cavity insertion rod 29. Due to the gap between the spring packaging frame 28 and the inner cavity insertion rod 29, these protruding decorations can be inserted into the groove created by the gap. The flatter part of the cosmetic bottle contacts the inner wall of the inner cavity insertion rod 29, causing the cosmetic bottle to be clamped. Furthermore, multiple sets of spring-loaded wrapping frames 28 are slidably connected by connecting ropes 30. The spring-loaded wrapping frames 28 are in a contracting and expanding state along the surface of the connecting ropes 30 due to the compression of the cosmetic bottles. The inner cavity insert rod 29 is compressed by cosmetic bottles of different diameters, causing the spring-loaded wrapping frames 28 to slide along the outer surface of the connecting ropes 30. During the sliding process, the spring-loaded wrapping frames 28 are clamped and limited by the bidirectional hollow clamps 27, causing the spring-loaded wrapping frames 28 to perform telescopic movements within the diameter of the bidirectional hollow clamps 27. The maximum range of change in the wrapping diameter formed by the spring-loaded wrapping frames 28 and the connecting ropes 30 is consistent with the value of the diameter from the bidirectional hollow clamps 27 to the center, thus adapting to the installation and testing of cosmetic bottles of different styles.

[0034] Refer to the instruction manual appendix Figure 8The inner cavity insert rod 29 is fixedly connected to the inside of the spring-wrapped frame 28. The inner wall of the inner cavity insert rod 29 is fixedly connected to a ring-shaped limiting rubber push cavity wall 34. The inner wall of the inner cavity insert rod 29 is fixedly connected to a buffer rubber frame 33. The inner cavity insert rod 31 with an internal cavity is fixedly connected to the inside of the buffer rubber frame 33. The outer wall of the inner ring cavity wall 32 fits against the outer wall of the limiting rubber push cavity wall 34. When the outer wall of the inner cavity insert rod 29 is squeezed, the inner cavity insert rod 29 transmits the pressure to the double hollow insert rod 31 through the buffer rubber frame 33. The double hollow insert rod 31 is compressed, causing the inner ring cavity wall 32 to expand outward. The inner ring cavity wall 32 expands outward by squeezing the limiting rubber push cavity wall 34. The inner cavity insert rod 29 relies on the bending pressure transmitted by the limiting rubber push cavity wall 34 to tightly grip the surface of the cosmetic bottle, thereby improving the stability of cosmetic bottle detection.
