DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0018] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a plastic barrel air tightness detection device includes a support assembly 100, a detection assembly 200 and a rotating assembly 400. Through the cooperation of these three components, the air tightness detection of the plastic barrel 300 is completed. Among them, the support assembly 100, as the basis of the entire detection device, plays an important role in stability and load bearing. The detection assembly 200 and the rotating assembly 400 are both connected to the support assembly 100, and the rotating assembly 400 is set at the lower part of the detection assembly 200, and the plastic barrel 300 is carried and driven to rotate by the rotating assembly 400.

[0019] In particular, the detection assembly 200 is provided with a detection cover 210, a detection column 220 and a signal receiving member 240. First, the detection cover 210 is used to connect with the threaded port of the plastic barrel 300, seal the plastic barrel 300, ensure that the gas does not leak during the detection process, and ensure the accuracy of the detection. Secondly, the detection column 220 is arranged on the upper part of the detection cover 210 and is connected to the detection cover 210, and a detection inner column 223 is arranged in the detection column 220. When the air pressure in the plastic barrel 300 changes, the length of the detection inner column 223 will change with the change of air pressure. Furthermore, the signal receiving member 240 is arranged on the upper part of the detection column 220, and a touch plate 241 is specially provided in the signal receiving member 240, and the touch plate 241 contacts the top of the detection inner column 223. When the detection inner column 223 is displaced due to the change of air pressure, the touch plate 241 can instantly capture this change and convert it into an electrical signal for output.

[0020] In order to tighten the plastic barrel 300 to be inspected and the inspection cover 210 together, a rotating disk 420 is involved in the rotating assembly 400. The plastic barrel 300 is placed on the rotating disk 420, and the rotating disk 420 is driven to rotate by the first motor 410, so that the plastic barrel 300 and the inspection cover 210 are tightened.

[0021] Specifically, the plastic barrel 300 to be inspected is placed on the rotating disk 420, and then the inspection cover 210 slowly descends from the top and tightly fits on the plastic barrel 300. At this time, the first motor 410 is started, driving the rotating disk 420 to rotate, and then driving the plastic barrel 300 to rotate, ensuring that the plastic barrel 300 and the inspection cover 210 are firmly threaded. After the connection is tight, a certain amount of air is injected into the plastic barrel 300 through the inflation connection pipe 260 at the top of the inspection cover 210, and its volume is slightly larger than the rated capacity of the plastic barrel 300. In this process, the gas pressure inside the plastic barrel 300 gradually increases, pushing the detection inner column 223 up until its top is in close contact with the touch plate 241.

[0022] It is particularly important that in order to accurately evaluate the sealing performance of the plastic barrel 300, the gas state in the barrel needs to be kept stable for a period of time. During this period, two situations may occur: first, if the plastic barrel 300 is well sealed, the volume of the gas in the barrel remains unchanged, and the top of the detection inner column 223 continues to contact the touch plate 241; second, if there is a leak in the plastic barrel 300, the volume of the gas in the barrel decreases, causing the detection inner column 223 to drop and the top to separate from the touch plate 241. At this time, the signal receiving component 240 will capture this change in time and transmit the relevant information so as to record and count the detection data of the plastic barrel 300.

[0023] It is worth noting that the detection cover 210 used in this embodiment is designed to match the plastic barrel 300, which not only achieves the sealing of the plastic barrel 300, but also effectively detects the integrity of its threaded connection port, thereby significantly improving the detection efficiency. In addition, the coordinated work of the detection inner column 223 and the signal receiving element 240 can intuitively and accurately reflect the sealing condition of the plastic barrel 300 by detecting the displacement change of the inner column 223, further improving the reliability and accuracy of the detection results.

[0024] like Figure 3 As shown, in some embodiments, the support assembly 100 is used as the basis of the entire device, and is provided with an upper support member and a lower support member. Among them, the detection assembly 200 is installed on the upper support member and is arranged on the upper part of the plastic barrel 300. The lower support member is connected to the rotating assembly 400, so that it stably carries the plastic barrel 300, ensuring the stability of the plastic barrel 300 during the detection process.

[0025] Specifically, the upper support member includes a support cross plate 130, a second through hole 140 and a plurality of support columns 150. The support cross plate 130, as an important component of the upper support member, has a flat surface to ensure that the detection assembly 200 can fit tightly after installation. In particular, a plurality of support columns 150 are installed on both sides of the support cross plate 130, so that the support cross plate 130 can be stably installed on the support platform 110, and a space is left between the support platform 110 to facilitate the installation of the plastic barrel 300. The detection column 220 and the signal receiving component 240 are respectively arranged on the upper and lower surfaces of the support cross plate 130. In order to achieve the connection between the detection column 220 and the signal receiving component 240, a second through hole 140 is specially arranged on the support cross plate 130.

[0026] The lower support member, as the base of the entire support assembly 100, includes a support platform 110, a first through hole 120 and a support frame 160. The support platform 110 plays a connecting role, and the first through hole 120 is set on the support platform 110. The first through hole 120 corresponds to the position of the second through hole 140, and the first through hole 120 is designed in the form of a step. The rotating disk 420 is installed in the first through hole 120, and the two are slidably connected, so that the rotating disk 420 can rotate smoothly, realizing the continuous and stable rotation of the plastic barrel 300 during the detection process.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, the detection assembly 200 also includes a first telescopic column 230, a fixing frame 250, an inflatable connecting pipe 260, a first connecting plate 270, a second connecting plate 280 and a fixing plate 290, which work together with the detection inner column 223 and the touch plate 241 to complete the detection operation of the plastic barrel 300. Among them, the first connecting plate 270 is arranged on the upper part of the supporting horizontal plate 130, and plays the role of fixing the signal receiving member 240. Specifically, the fixing plate 290 is installed on the upper part of the first connecting plate 270, and the fixing frame 250 serves as a carrier of the signal receiving member 240, and its stability directly affects the accuracy of the detection result.

[0028] Corresponding to the first connecting plate 270 is a second connecting plate 280 disposed at the lower portion of the supporting horizontal plate 130, which plays the role of supporting the detection cover 210. The second connecting plate 280 is connected to the fixing plate 290 through the first telescopic column 230, and is connected to the detection cover 210 at the lower portion of the fixing plate 290, and the first telescopic column 230 moves downward to buckle the detection cover 210 at the opening of the plastic barrel 300. In particular, while the rotating assembly 400 rotates, the first telescopic column 230 continues to move downward slowly, so that the detection cover 210 and the plastic barrel 300 can be completely tightened.

[0029] The inflation connecting tube 260 serves as an important channel connecting the detection cover 210 with the external inflation pump. One end of the inflation connecting tube 260 is connected to the detection cover 210, and the other end is connected to the external inflation pump. By controlling the switch and air pressure of the inflation pump, precise control of the internal air pressure of the detection component 200 can be achieved.

[0030] A third through hole 271 is provided on the first connecting plate 270 and the second connecting plate 280 . The third through hole 271 is provided corresponding to the second through hole 140 . The detection column 220 and the inflation connecting tube 260 pass through the third through hole 271 .

[0031] Furthermore, in some embodiments, the detection column 220 further includes a detection outer tube 221 and a plugging plate 222. The detection outer tube 221 is welded and fixed to the detection cover 210, and the inner diameter of the detection outer tube 221 is connected to the detection cover 210 to achieve gas circulation between the plastic barrel 300 and the detection column 220. The plugging plate 222 is arranged in the detection outer tube 221 and forms a sliding connection with the inner wall of the detection outer tube 221.

[0032] In particular, the bottom of the detection inner column 223 is firmly connected to the plugging plate 222 . This design ingeniously ensures that during the detection process, the detection inner column 223 can closely follow the movement of the plugging plate 222 , thereby achieving accurate feedback on the internal gas pressure of the plastic barrel 300 .

[0033] Furthermore, in some embodiments, the signal receiving component 240 also includes an adjusting rod 242, the bottom of the adjusting rod 242 is fixedly connected to the touch panel 241, and the adjusting rod 242 is threadedly connected to the fixed frame 250. By rotating the adjusting rod 242, the length of the lower end of the adjusting rod 242 extending out of the fixed frame 250 is adjusted, thereby adjusting the height of the touch panel 241.

[0034] like Figure 7 As shown, in some embodiments, the rotating assembly 400 is further provided with a first motor 410, a surrounding plate 430 and a limit plate 440. Among them, the first motor 410 is closely connected to the support frame 160 to form a stable transmission foundation. Through the forward and reverse rotation of the first motor 410, the fastening and loosening operations between the detection cover 210 and the plastic barrel 300 are flexibly realized. In addition, the rotating disk 420 is connected to the first motor 410 through transmission to ensure the smooth operation.

[0035] The enclosure 430 is designed to be semi-circular, and its inner surface fits against the outer wall of the plastic barrel 300. It is installed on the upper part of the rotating disk 420 and works in conjunction with the limit plate 440 to effectively and firmly restrict the plastic barrel 300 above the rotating disk 420, thereby playing its function of fixing the plastic barrel 300 and ensuring that the plastic barrel 300 does not rotate with the rotating disk 420 during the rotation process.

[0036] In particular, a limiting groove 450 is further provided on the upper portion of the rotating disk 420, and the limiting plate 440 is inserted into the limiting groove 450. The design of the limiting groove 450 allows the limiting plate 440 to be quickly installed. In order to achieve the stability of the limiting plate 440, a support foot is specially installed on the limiting plate 440 to prevent the position of the limiting plate 440 from shaking.

[0037] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, to achieve sealing between the detection cover 210 and the plastic barrel 300, the detection cover 210 is connected with a detection thread 211 matching the threaded opening of the plastic barrel 300, and a sealing gasket 212 is carefully designed inside the detection cover 210. This design is intended to more effectively seal the plastic barrel 300.

[0038] In actual operation, when the detection cover 210 is tightly connected to the threaded opening of the plastic barrel 300, the sealing gasket 212 will be compressed and fill the small gap between the two to form a sealing barrier. At this time, by injecting a certain volume of gas into the plastic barrel 300 and observing the detection component 200 to see whether the gas in the plastic barrel 300 can remain leak-free within a specified time, it is possible to accurately determine whether the airtightness of the plastic barrel 300 meets the standard.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0041] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
