DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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] A facial mask packaging bag airtightness tester includes a chassis 1, a water tank 2, a frame 3 and a hanger 5. The chassis 1 is used to be fixed on the laboratory floor. The water tank 2 and the frame 3 are fixedly installed on the chassis 1. The water tank 2 is filled with water required for the detection experiment. The frame 3 is installed with a lifting drive mechanism 4. The hanger 5 is transmission-connected to the lifting drive mechanism 4. The hanger 5 is installed with a sample holder 6. The facial mask packaging bag sample can be fixed on the sample holder 6. The hanger 5 can be driven to perform lifting movement by the lifting drive mechanism 4. When the sample holder 6 is above the water tank 2, the experimenter completes the installation of the facial mask packaging bag sample, and then the lifting drive mechanism 4 can drive the hanger 5 to descend, so that the sample holder 6 is immersed in the water tank 2. The facial mask packaging bag sample required for the detection experiment is filled with air in advance and sealed. Sealed. After the mask packaging bag sample is immersed in the water tank 2, the airtightness of the mask packaging bag sample can be intuitively understood by observing whether there are bubbles around the mask packaging bag sample. During the detection experiment, the mask packaging bag sample is first immersed in water. At this time, the static airtightness is detected, and then the dynamic airtightness of the mask packaging bag sample needs to be detected. The utility model is equipped with a pressure auxiliary mechanism 8 in the water tank 2. The pressure auxiliary mechanism 8 can cooperate with the sample seat 6 to form a pressure effect on the mask packaging bag sample, so as to detect the dynamic airtightness of the mask packaging bag sample under pressure. The utility model has the advantages of easy operation and clear test results. The utility model can well help experimenters complete the airtightness detection experiment of new packaging bags.

[0023] like Figure 4 As shown, the lifting drive mechanism 4 includes side panels 41, cross beams 42, screws 43, lifting beams 44 and motors 45. The two side panels 41 are vertically mounted on the top of the frame 3. The cross beams 42 are fixedly connected to the tops of the two side panels 41. The screws 43 are rotatably mounted between the two side panels 41. The screws 43 are arranged parallel to the side panels 41. The screws 43 are vertically rotatably mounted. One end of the screws 43 is connected to the cross beams 42 and the other end is connected to the frame 3. The two side panels 41 are both equipped with guide rails 411. The beam 44 is mounted on two guide rails 411. The guide rails 411 guide the movement of the lifting beam 44. The lifting beam 44 can move along the length direction of the guide rails 411. The lifting beam 44 is also threadedly connected to the screw 43. The motor 45 is mounted on the top of the beam 42. The output end of the motor 45 is connected to the screw 43. When the motor 45 is started, it can drive the screw 43 to rotate, and then the lifting beam 44 can move along the length direction of the guide rails 411. That is, the lifting beam 44 performs a vertical lifting movement. Figure 1As shown, a flange seat 51 is installed on the top of the hanger 5, and the hanger 5 is connected to the side wall of the lifting beam 44 through the flange seat 51. The sample seat 6 is fixedly installed on the bottom of the hanger 5. The hanger 5 and the lifting beam 44 are connected by bolt flanges, which are convenient for disassembly and replacement. When the lifting beam 44 performs vertical lifting movement, it can form a lifting and lowering movement effect of the hanger 5 and the sample seat 6. When the sample seat 6 is lifted above the water tank 2, the mask packaging bag sample can be installed or replaced. After the sample seat 6 is lowered into the water tank 2, the mask packaging bag sample is immersed in water, and an airtightness test experiment in a water environment can be carried out.

[0024] like Figure 2 As shown, the sample holder 6 is L-shaped, and a plurality of bag clips 61 are installed on the top of the sample holder 6. The bag clips 61 are arranged in a horizontal straight line. The mask packaging bag samples can be clamped by the bag clips 61. The design of multiple bag clips 61 is used to ensure that the mask packaging bag samples are fixed reliably. Generally, 2-3 bag clips 61 are selected. The mask packaging bag samples are clamped upright on the sample holder 6. The upright mounted mask packaging bag samples are conducive to pressure operation.

[0025] like Figure 3 As shown, linkage plate frames 52 are symmetrically installed on both sides of the hanger 5. The linkage plate frames 52 can move up and down with the hanger 5. An underwater camera 7 is installed on each linkage plate frame 52. The underwater camera 7 is set corresponding to the direction of the sample holder 6. The underwater camera 7 can work in an underwater environment. The underwater camera 7 is immersed in water together with the sample holder 6. The underwater camera 7 can monitor the water surface around the facial mask packaging bag sample on the sample holder 6 in real time, and promptly detect whether there is any bubble generation.

[0026] like Figure 2 As shown, the pressure auxiliary mechanism 8 includes a pressure push cylinder 81 and a limit seat 83. The pressure push cylinder 81 is fixedly connected to the side wall of the water tank 2. The piston rod end of the pressure push cylinder 81 is connected to the third push plate 82. The third push plate 82 is arranged in the water tank 2. The third push plate 82 can move toward the sample seat 6. The limit seat 83 is fixedly installed in the water tank 2. The limit seat 83 blocks the downward path of the sample seat 6. The limit seat 83 plays a role in limiting the downward limit of the sample seat 6. An extrusion seat 62 is installed on the sample seat 6. When the sample seat 6 contacts the limit seat 83, the sample seat 6 drops to the underwater limit position. The extrusion seat 62 just corresponds to the movement path of the third push plate 82. At this time, the pressure push cylinder 81 drives the third push plate 82 to move toward the extrusion seat 62, which can drive the extrusion seat 62 to form an extrusion force effect on the upright facial mask packaging bag sample. Under the extrusion action, the airtightness quality of the facial mask packaging bag sample can be better reflected.

[0027] like Figure 2As shown, the extrusion seat 62 includes a moving rod 621, a first push plate 622 and a second push plate 623. The moving rod 621 is installed through the side wall of the sample holder 6. The moving rod 621 is provided with two parallel upper and lower rods. The first push plate 622 and the second push plate 623 are respectively connected to the two ends of the moving rod 621. The first push plate 622 is set toward the direction of the mask packaging bag sample, and the second push plate 623 is set toward the direction of the pressure push cylinder 81. The moving rod 621 plays a role in guiding the movement of the extrusion seat 62, so that it can only move laterally. When the pressure auxiliary mechanism 8 takes effect, the third push plate 82 applies force on the second push plate 623, and then drives the first push plate 622 to form an extrusion force effect on the side wall of the upright mask packaging bag sample.

[0028] like Figure 1 As shown, a controller 31 is installed on the side of the frame 3. The controller 31 is provided with a plurality of buttons. The controller 31 can control the lifting movement of the sample holder 6 and the start and stop of the pressure auxiliary mechanism 8.
