Description

Technical Field

[0001] This utility model belongs to the technical field of bubble bag detection, and specifically relates to a bubble bag air leakage detection device. Background Technique

[0002] As a common packaging material, bubble bags are widely used in the transportation and storage of electronic products, fragile items, and other items that require protection.

[0003] Bubble bags can provide good buffering and shockproof effects, thus protecting the items inside from external impacts. However, if there is an air leakage problem in the bubble bag, its protective performance will be greatly affected; therefore, detecting whether there is an air leakage in the bubble bag is of great significance for ensuring the packaging quality.

[0004] The existing methods for detecting air leakage in bubble bags mainly include visual inspection method, water immersion method, and compressed air detection method. Among them, the compressed air detection method uses compressed air to pressurize the bubble bag and detects the pressure change to determine whether there is air leakage;

[0005] Since the sealing of the bubble bag is usually achieved by hot pressing during use, when not in use, one end of the bubble bag will have a relatively large opening, and it needs to be sealed before detection. However, due to its large opening, the existing sealing methods are mostly clamping seals, which complete the sealing of the opening of the bubble bag by applying clamping forces to the upper and lower sides of the opening end of the bubble bag. The sealing effect is limited, and since the opening end of the bubble bag needs to insert an inflation tube, gaps are likely to occur at the position where the bubble bag contacts the inflation tube, which will further affect its sealing effect. As a result, during the air leakage detection of the bubble bag, misdetection is likely to occur due to air leakage at the opening of the bubble bag body. Content of the Utility Model

[0006] The purpose of this utility model is to provide a bubble bag air leakage detection device that can perform two-stage pressurized sealing on the opening of the bubble bag body, reduce the gaps at the opening of the bubble bag body, have good sealing performance, and thus reduce the misdetection phenomenon caused by air leakage at the opening of the bubble bag body during the air leakage detection of the bubble bag body.

[0007] The technical solution adopted by this utility model is specifically as follows:

[0008] A bubble bag air leakage detection device includes a first clamping plate, a second clamping plate, and an air delivery tube. One end of the air delivery tube is connected to an air inflation pump, and the other end of the air delivery tube is connected to an inflation head. The distance between the second clamping plate and the first clamping plate is adjustable, and clamping areas are provided on the mutually approaching sides between the first clamping plate and the second clamping plate. Plastic deformation pressure strips are installed on the clamping areas, and the plastic deformation pressure strips can extend towards the middle position between the first clamping plate and the second clamping plate.

[0009] Further, the plastic deformation pressing strip includes a strip-shaped airbag, an air pump unit, and an air duct. The strip-shaped airbag is fixedly connected to the clamping area, and the output end of the air pump unit is fixedly connected to one end of the air duct, and the other end of the air duct is fixedly connected to the strip-shaped airbag.

[0010] Further, a strip-shaped groove is formed in the clamping area. The strip-shaped groove is open on one side facing the middle position of the first clamping plate and the second clamping plate. The strip-shaped airbag is fixedly connected inside the strip-shaped groove, and the strip-shaped airbag can extend to the outside of the strip-shaped groove through the opening of the strip-shaped groove.

[0011] Further, arc-shaped grooves are formed on the mutually adjacent sides of the first clamping plate and the second clamping plate. The arc-shaped grooves communicate with the strip-shaped groove, and the two arc-shaped grooves can be combined into a circular through hole.

[0012] Further, a rigid tube body is fixedly connected to the outside of the air duct, and the rigid tube body can be placed inside the arc-shaped groove.

[0013] Further, an electric push rod is fixedly connected to the lower side of the first clamping plate, and the output end of the electric push rod is fixedly connected to the second clamping plate.

[0014] The technical effects achieved by this utility model are as follows:

[0015] An air bubble bag air leakage detection device of this utility model first presses and seals the opening of the air bubble bag body through the first clamping plate and the second clamping plate, and then performs secondary pressing and sealing on the opening of the air bubble bag body through the plastic deformation pressing strip, which can reduce the gap at the opening of the air bubble bag body, has good sealing performance, reduces the misdetection phenomenon caused by air leakage at the opening of the air bubble bag body during the air leakage detection of the air bubble bag body, and the sealing method is simple and the use is relatively convenient.

[0022] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation modes of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.

[0023] As Figure 1-2 shown, a bubble bag air leakage detection device includes a first splint 1, a second splint 2 and an air delivery pipe 10. One end of the air delivery pipe 10 is connected to an air inflation pump, and the other end of the air delivery pipe 10 is connected to an inflation head 11. After the air inflation pump is started, it will supply air to the inflation head 11 through the air delivery pipe 10 and discharge it through the inflation head 11;

[0024] The distance between the second splint 2 and the first splint 1 is adjustable, so that the distance between the first splint 1 and the second splint 2 can be adjusted according to the needs of the user, enabling the first splint 1 and the second splint 2 to clamp and seal the open end of the bubble bag body 7, thereby completing the sealing process of the bubble bag body 7 and making the bubble bag body 7 form a sealed structure.

[0025] Specifically, the distance between the first splint 1 and the second splint 2 can be adjusted by a threaded rod, that is, a threaded rod is rotatably connected to the first splint 1, and the threaded rod is threadedly connected to the second splint 2. Or as Figure 1-2 shown, an electric push rod 3 is fixedly connected to the lower side of the first splint 1, and the output end of the electric push rod 3 is fixedly connected to the second splint 2, so that the distance between the first splint 1 and the second splint 2 can be adjusted by the electric push rod 3, and the adjustment method is relatively simple.

[0026] As Figure 1-2As shown in the figure, clamping areas are provided on the mutually approaching sides between the first clamping plate 1 and the second clamping plate 2. Plastic deformation pressure strips are installed on the clamping areas. The plastic deformation pressure strips can extend towards the middle position between the first clamping plate 1 and the second clamping plate 2. When the open end of the bubble bag body 7 is placed between the first clamping plate 1 and the second clamping plate 2, the inflation head 11 is inserted into the interior of the bubble bag body 7 through the open end of the bubble bag body 7. Then, the electric push rod 3 is started to drive the second clamping plate 2 to move, so that the first clamping plate 1 and the second clamping plate 2 clamp and seal the open end of the bubble bag body 7. After the clamping is completed, the plastic deformation pressure strip is moved towards the direction close to the bubble bag body 7 until the plastic deformation pressure strip is in full contact with the bubble bag body 7. Since the plastic deformation pressure strip is stressed to squeeze the bubble bag body 7, the side of the plastic deformation pressure strip in contact with the bubble bag body 7 is set to be in imitation of the bubble bag body 7, which can further reduce the gap at the opening of the bubble bag body 7, thereby performing secondary pressure sealing on the open end of the bubble bag body 7, achieving a better sealing effect, ensuring the accuracy of air leakage detection, and having a simple sealing method and being relatively convenient to use.

[0027] As Figure 2 shown in the figure, the plastic deformation pressure strip includes a strip-shaped airbag 4, an air pump unit 5 and an air duct 6. The strip-shaped airbag 4 is fixedly connected to the clamping area, and the output end of the air pump unit 5 is fixedly connected to one end of the air duct 6, and the other end of the air duct 6 is fixedly connected to the strip-shaped airbag 4. After the air pump unit 5 is started, it will inflate the strip-shaped airbag 4 through the air duct 6. The inflated strip-shaped airbag 4 will extend towards the direction close to the bubble bag body 7 until it fully pressurizes the bubble bag body 7. By utilizing the excellent deformation performance of the strip-shaped airbag 4, it can complete the pressure sealing of the bubble bag body 7 through a relatively simple structure, and during use, the volume of the strip-shaped airbag 4 can be adjusted by inflating and deflating the air pump unit 5 to complete the pressurization and decompression of the bubble bag body 7, and the use method is relatively simple.

[0028] Meanwhile, the material of the strip-shaped airbag 4 is preferably latex, which has good deformation performance.

[0029] Meanwhile, the plastic deformation pressure strip can also be a latex strip. A plate body is fixedly connected to the side of the latex strip close to the clamping area, and then a hydraulic cylinder is arranged on the first clamping plate 1 or the second clamping plate 2 on the plate body, so that the plate body and the latex strip can be pushed and moved.

[0030] As Figure 2-3As shown, a strip-shaped groove 8 can be formed in the clamping area. The strip-shaped groove 8 is open on the side facing the middle position between the first clamping plate 1 and the second clamping plate 2. The strip-shaped airbag 4 can be fixedly connected inside the strip-shaped groove 8, that is, the strip-shaped airbag 4 is completely contracted inside the strip-shaped groove 8 initially, so as to reduce the mutual interference phenomenon between the strip-shaped airbag 4 when not inflated and expanded and the bubble bag body 7 and the air delivery pipe 10. Moreover, the strip-shaped airbag 4 can extend to the outside of the strip-shaped groove 8 through the opening of the strip-shaped groove 8 to press and seal the bubble bag body 7.

[0031] As Figure 2-3 shown, in order to reduce the phenomenon that the air delivery pipe 10 is pressed and suffocated, arc-shaped grooves 9 are formed on the mutually close sides of the first clamping plate 1 and the second clamping plate 2. The arc-shaped grooves 9 are communicated with the strip-shaped groove 8, and the two arc-shaped grooves 9 can be combined into a circular through hole. The air delivery pipe 10 can be placed inside the arc-shaped groove 9, and then the strip-shaped airbag 4 is used to press and seal the area around the air delivery pipe 10, so as to reduce the phenomenon that the air delivery pipe 10 is clamped and flattened due to hard contact with the first clamping plate 1 and the second clamping plate 2 and thus suffocated.

[0032] At the same time, as Figure 2-4 shown, a rigid pipe body 12 can also be fixedly connected to the outside of the air delivery pipe 10. The air delivery pipe 10 can be made of materials that are not easily deformed, such as metal and hard rubber. When inflated, due to the relatively hard material of the air delivery pipe 10, the pressure exerted by the strip-shaped airbag 4 on the air delivery pipe 10 can be reduced, and the phenomenon of pressure-induced deformation of the air delivery pipe 10 can be reduced;

[0033] moreover, the rigid pipe body 12 can be placed inside the arc-shaped groove 9, so as to reduce the phenomenon that a large gap is generated between the first clamping plate 1 and the second clamping plate 2 due to the rigid pipe body 12 being located between the first clamping plate 1 and the second clamping plate 2, and at the same time, it can also reduce the phenomenon that the first clamping plate 1 and the second clamping plate 2 exert a large pressure on the rigid pipe body 12, resulting in deformation of the rigid pipe body 12 and exerting pressure on the air delivery pipe 10.

[0034] The working principle of this utility model is as follows: Place the open end of the bubble bag body 7 between the first clamping plate 1 and the second clamping plate 2, insert the inflation head 11 into the bubble bag body 7 through the open end of the bubble bag body 7, and then start the electric push rod 3 to drive the second clamping plate 2 to move, so that the first clamping plate 1 and the second clamping plate 2 clamp and seal the open end of the bubble bag body 7. After the clamping is completed, start the air pump unit 5. After the air pump unit 5 is started, it will inflate the strip-shaped airbag 4 through the guide air pipe 6. After inflation, the strip-shaped airbag 4 will extend towards the direction close to the bubble bag body 7 until it fully presses the bubble bag body 7, further reducing the gap at the opening of the bubble bag body 7, thereby performing secondary pressure sealing on the open end of the bubble bag body 7 to achieve a better sealing effect and ensure the accuracy of air leakage detection;

[0035] After the opening of the bubble bag body 7 is sealed, start the air pump to inflate the inside of the bubble bag body 7 to detect whether the bubble bag body 7 leaks air.

[0036] In summary, in this technical solution, the first clamping plate 1 and the second clamping plate 2 are used to perform a primary pressure sealing on the opening of the bubble bag body 7, and then the plastic deformation pressure strip is used to perform a secondary pressure sealing on the opening of the bubble bag body 7, which can reduce the gap at the opening of the bubble bag body 7, has good sealing performance, and reduces the misdetection phenomenon caused by air leakage at the opening of the bubble bag body 7 during the air leakage detection of the bubble bag body 7. Moreover, the sealing method is simple and easy to use.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special explanation and limitation.
