Description

Technical Field

[0001] This utility model relates to the technical field of vacuum sealing testers, specifically a vacuum sealing tester for cosmetic packaging materials. Background Technology

[0002] The cosmetic packaging vacuum seal tester is mainly used to test the sealing performance of packaging to ensure that the product will not leak or become contaminated during use, while ensuring that the product quality meets regulatory standards.

[0003] There are still some drawbacks in the current process of vacuum sealing testing of cosmetic packaging materials. Since the packaging material is placed directly inside the instrument after expansion, and the packaging material is tested for airtightness from all directions, this testing method is difficult to specifically measure minute leaks or blind spots in the packaging material. Therefore, the effectiveness of the test varies.

[0004] In view of this, a vacuum sealing tester for cosmetic packaging materials was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A vacuum sealing tester for cosmetic packaging materials includes a test body, a test assembly installed inside the test body, and a packaging material partitioning assembly installed within the test assembly. The test assembly includes a chassis, with a symmetrically distributed upper cover plate and a lower cover plate fixedly installed on the front of the chassis, and a back plate fixedly installed on the back of the chassis. A drawer plate is snapped between the upper cover plate and the lower cover plate. Two sets of symmetrically distributed limiting pads are fixedly installed on the inner side of the drawer plate. Two first end plates and one second end plate are fixedly installed on the bottom of the chassis. A support plate is fixedly installed on the outside of the drawer plate. A horizontally placed bidirectional lead screw is movably installed on the bottom of the support plate, and the threaded section of the bidirectional lead screw is adapted to be installed in the second end plate. The inner wall of the chassis has symmetrically distributed rectangular slides. The packaging material partitioning assembly includes beam rails movably installed in the rectangular slides. A protective outer plate is fixedly installed on the outside of the beam rails. A partition cover is inserted between two adjacent beam rails, and a pad is fixedly installed on the port of the partition cover facing the packaging material.

[0007] In a preferred embodiment, the present invention can be further configured such that: guide rods are fixedly installed in both plate segments at the bottom of the lower cover plate, and the guide rods are adapted to penetrate into the first end plate.

[0008] In a preferred embodiment, the present invention can be further configured such that a cylindrical soft pad is fixedly installed on the inner side of the limiting inner pad, and the cylindrical soft pad has a hollow structure.

[0009] In a preferred embodiment, the present invention can be further configured as follows: two sets of clamps are fixedly installed on the outer wall of the chassis, hydraulic components are fixedly installed inside the two sets of clamps, adapters are installed on the hydraulic components, a lever arm is movably installed on the adapter, a support plate is movably installed at the other end of the lever arm, and two symmetrically distributed traction plates are movably installed on the support plate.

[0010] In a preferred embodiment, the present invention can be further configured such that: two symmetrically distributed pads are fixedly installed on both sides of the back plate, an end rod is fixedly installed on the pad, a spring is provided on the outside of the end rod, and the end rod extends into the tray, with the inner end of the spring adapted to bear pressure on the tray.

[0011] In a preferred embodiment, the present invention can be further configured such that: a clamp is fixedly installed on the outside of the protective outer plate, and the other end of the traction plate is movably installed on the clamp.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model involves the movable installation of two symmetrically distributed sets of beam rails inside the chassis, and the movable installation of symmetrically distributed partition covers between adjacent sets of beam rails. Gaskets are fixedly installed on the partition covers. After the expanded packaging material is pre-loaded by the drawer plate and the two sets of limiting inner gaskets, the expanded packaging material will finally be inserted between the two partition covers. The two partition covers will then press against the top and bottom surfaces of the expanded packaging material. The airtightness of the packaging material can be measured in three stages using three pipes on the back plate, thereby enabling targeted detection of minor leaks and blind spots in the packaging material.

[0013] 2. This utility model secures soft pads to the inside of the limiting pad, and uses multiple soft pads to fit and press the two sides of the expanded packaging material together. With the relative clamping of two partition covers and two bladder pads, it can ultimately ensure that the expanded packaging material will not bounce abnormally inside the box during the testing period.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of a cosmetic packaging vacuum sealing tester.

[0019] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a vacuum sealing tester for cosmetic packaging materials, including a test body 100, a test component 200 installed in the test body 100, and a packaging material partitioning component 300 installed in the test component 200. The test component 200 is used to perform effective airtightness testing on the expanded packaging material, and the packaging material partitioning component 300 is used to perform three-stage leakage zone or blind zone testing on the expanded packaging material.

[0020] The detection assembly 200 includes a chassis 210. A symmetrically distributed upper cover plate 2104 and lower cover plate 2105 are fixedly mounted on the front of the chassis 210. A back plate 240 is fixedly mounted on the back of the chassis 210. A drawer plate 220 is snapped between the upper cover plate 2104 and the lower cover plate 2105. Two symmetrically distributed sets of limiting pads 2201 are fixedly mounted on the inner side of the drawer plate 220. Two first end plates 2101 and one second end plate 2102 are fixedly mounted on the bottom of the chassis 210. A support plate 2202 is fixedly installed on the outside of the drawer plate 220. A horizontally placed double-acting screw 230 is movably installed at the bottom of the support plate 2202. The threaded section of the double-acting screw 230 is adapted to be installed in the second end plate 2102. Guide rods 2106 are fixedly installed in the two plate sections at the bottom of the lower cover plate 2105. The guide rods 2106 are adapted to pass through the first end plate 2101. A cylindrical soft pad is fixedly installed on the inner side of the limiting pad 2201. The cylindrical soft pad has a hollow structure. The inner wall of the chassis 210 is provided with symmetrically distributed rectangular slides; The packaging material partitioning assembly 300 includes a beam rail 310 movably installed in a rectangular slide, a protective outer plate 320 fixedly installed on the outside of the beam rail 310, a partition cover 330 inserted between two adjacent beam rails 310, a pad 340 fixedly installed on the port of the partition cover 330 facing the packaging material, a clamp 3201 fixedly installed on the outside of the protective outer plate 320, and the other end of the traction plate 2504 movably installed on the clamp 3201.

[0021] In use, first rotate the bidirectional lead screw 230 until the bidirectional lead screw 230 drives the support plate 2202 and the drawer plate 220 to extend outward, and the two sets of limiting inner pads 2201 fixedly installed on the inner side of the drawer plate 220 will detach from the inner cavity of the chassis 210. Then, insert the expanded packaging material through the gap of the two sets of limiting inner pads 2201. At this time, the side of the expanded packaging material will be limited and clamped by the two sets of limiting inner pads 2201. Then rotate the bidirectional lead screw 230 again until the support plate 2202 drives the drawer plate 220 and the two sets of limiting inner pads 2201 to re-insert into the inner cavity of the chassis 210 until the expanded packaging material is located in the middle of the inner cavity of the chassis 210. Next, the hydraulic component 250 is operated via the cloud until the hydraulic sub-rod inside the hydraulic component 250, in conjunction with the adapter 2501, pushes the lever arm 2502 and the support plate 2503 to extend. The support plate 2503 then pushes the two traction plates 2504 to retract relative to each other. Finally, the traction plates 2504 drive the protective outer plate 320, the beam rail 310, and the partition cover 330 to fit and press against the outer surface of the expanded packaging material. The expanded packaging material can then be divided into three sections. The three cavities after partitioning are vacuumed through the three pipes on the back plate 240, which facilitates the three-section inspection of the expanded packaging material.

[0022] Example 2: Combination Figure 4 and Figure 5 As shown, in the above embodiment, two sets of clamps 2103 are fixedly installed on the outer wall of the chassis 210, and hydraulic components 250 are fixedly installed inside the two sets of clamps 2103. An adapter 2501 is installed on the hydraulic component 250, a lever arm 2502 is movably installed on the adapter 2501, a support plate 2503 is movably installed on the other end of the lever arm 2502, and two symmetrically distributed traction plates 2504 are movably installed on the support plate 2503. Two symmetrically distributed pads 2401 are fixedly installed on both sides of the back plate 240. An end rod 2402 is fixedly installed on the pad 2401. A spring 2403 is provided on the outside of the end rod 2402, and the end rod 2402 extends into the support plate 2503. The inner end of the spring 2403 is adapted to bear pressure on the support plate 2503.

[0023] Preferably, a circular washer is fixedly installed on the outside of the end rod 2402, and the outer end of the spring 2403 is fixedly installed on the circular washer, while the other end of the spring 2403 is fixedly installed on the outer surface of the support plate 2503. The two adjacent protective outer plates 320 are adapted to be snapped into the vertical groove of the outer wall of the chassis 210, and the U-shaped frame at both ends of the bidirectional lead screw 230 can provide longitudinal limiting protection for the two adjacent protective outer plates 320. This method can be used in conjunction with the two partition covers 330 and the two pads 340 to clamp the expansion packaging material on both sides.

[0024] The working principle and usage process of this utility model are as follows: The bidirectional lead screw 230 is rotated in advance until the bidirectional lead screw 230 drives the support plate 2202 to extend outward. The drawer plate 220 fixed at the top of the support plate 2202 will detach outward from the gap between the upper cover plate 2104 and the lower cover plate 2105. The two sets of limiting pads 2201 fixedly installed on the inner side of the drawer plate 220 are pulled outward from the machine box 210. Then, the expanded cosmetic packaging material is inserted along the gap between the two sets of limiting pads 2201 until the two sides of the packaging material are squeezed in along the gap between the two adjacent limiting pads 2201. The soft pads fixedly installed on the inner side of the limiting pads 2201 will fit and press tightly on the outer surface of the packaging material. Then, the drawer plate 220 with the expanded packaging material and the two sets of limiting inner pads 2201 are reinserted into the inner cavity of the chassis 210 until the expanded packaging material is located between the two partition covers 330. Next, the hydraulic component 250 is operated until the hydraulic rod inside the hydraulic component 250 retracts. The adapter 2501 fixed at the outer end of the hydraulic rod will push the lever arm 2502 to extend outward. Finally, the other end of the lever arm 2502 will push the support plate 2503 and the two traction plates 2504 to extend relative to each other. The two traction plates 2504 will drive the two sets of clamps 3201 and the protective outer plate 320 to retract relative to each other along the vertical groove on the outer wall of the chassis 210 until the two beam rails 310 will drive the two partition covers 330 to relatively fit and press against the upper and lower surfaces of the expansion packaging material. Finally, the two pads 340 will adapt and clamp the surface of the expansion packaging material. The side of the packaging material will be located in the cavity in the middle of the two partition covers 330 and the chassis 210. The three pipes on the back plate 240 are used to perform vacuum detection on the three cavities of the chassis 210 after it is divided. This process can perform three-point detection on the expanded packaging material.
