DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. As long as the effects of the utility model can be achieved, various changes can be made to the implementation solutions.

[0030] The components in the case will be connected in sequence by the personnel in the field, and the specific connection and operation sequence should be referred to the following working principles. The detailed connection means is the known technology in the field, and the following mainly introduces the working principles and processes.

[0031] Reference Figures 1-8 An online sealing detection device for bottle type bodies is described for the implementation solution.

[0032] The detection device in the embodiment is arranged between the first conveying belt 11 and the second conveying belt 12. The first conveying belt 11 and the second conveying belt 12 are used to convey the bottle bodies to the packaging line. In order to facilitate the placement of the detection device, the positions of the first conveying belt 11 and the second conveying belt 12 are adjusted in the implementation process, so that a gap is formed in the middle of the two belts to accommodate the detection device.

[0033] In the embodiment, the detection device comprises a plurality of cylinders 3, each cylinder 3 is fixed on the first conveying belt 11 and / or the second conveying belt 12 by a fixing frame. A first electric telescopic rod 1 and a second electric telescopic rod 6 are arranged above and below the cylinder 3 respectively. In the setting, the first electric telescopic rod 1 and the second electric telescopic rod 6 need to be fixed on a fixed object. In a preferred embodiment, the fixed object is preferably a rack, which is fixed on the ground or the first conveying belt 11 and / or the second conveying belt 12.

[0034] In a preferred embodiment, the output end of the first electric telescopic rod 1 is fixed with a cover 2 that can be buckled on the top of the cylinder 3, and the output end of the second electric telescopic rod 6 is fixed with an inner table body 7 that can move up and down in the cylinder 3. When the inner table body 7 is at the highest point, it is flush with the top surface of the first conveying belt 11 and the second conveying belt 12, and when it is at the lowest point, it is at the bottom position of the cylinder 3. The top end and the bottom end of the cylinder 3 are respectively fixed with an upper flange 4 and a lower flange 5, wherein when the cover 2 is buckled on the top of the cylinder 3, it abuts against the upper flange 4; when the inner table body 7 is at the lowest point, it abuts against the lower flange 5. One side of the cylinder 3 is provided with a vacuum pump.

[0035] The cylinder 3 is connected with a test element of a tester for detecting the change of test pressure in the cylinder 3. In the specific implementation, the bottle body is conveyed along the first conveying belt 11 to the second conveying belt 12. When it is conveyed to the position of the cylinder 3, it stops on the surface of the inner table body 7 at the highest position. The second electric telescopic rod 6 is lowered to lower the inner table body 7 to the bottom to close the bottom end of the cylinder 3, and the bottle body enters the cylinder 3. The first electric telescopic rod 1 drives the cover 2 to be lowered and buckled to the top end of the cylinder 3 to close the top end of the cylinder 3. The vacuum pump works to suck the air in the cylinder 3, and then the tester detects the change of test pressure in the cylinder 3. For example, the inside of the cylinder 3 is sucked to-50kPa, and the pressure is maintained for 3 seconds. If there is no change in the air pressure in the cylinder 3 within 2 seconds, it is determined that the detection is qualified.

[0036] In order to adapt to the online detection, the vacuumizing device in the embodiment comprises a three-way electromagnetic valve 8 which is communicated with the cylinder 3 at one end, and the other two ends of the three-way electromagnetic valve 8 are communicated with an external cavity 9 and an exhaust pipe 10 respectively, and the external cavity 9 and the exhaust pipe 10 are both connected with a vacuum pump. In the implementation, the three-way electromagnetic valve 8 is closed, and the vacuum pump sucks the air inside the external cavity 9 to make the inside of the external cavity 9 in vacuum. After the upper and lower ends of the cylinder 3 are closed, the three-way electromagnetic valve 8 is opened to make the external cavity 9 communicated with the cylinder 3, and the air pressure inside the two is balanced quickly. Then the external cavity 9 is closed, and the exhaust pipe 10 is opened to continue sucking the air inside the cylinder 3. In this way, the vacuumizing speed of the cylinder 3 is improved, and the vacuumizing device is more suitable for the vacuum detection in the online conveying process.

[0037] In a preferred embodiment, the upper flange 4 is butterfly-shaped, and the extension parts are formed at the two ends of the upper flange 4 to extend outward. The extension parts are close to the upper surfaces of the first conveying belt 11 and the second conveying belt 12, so that the bottle is more smoothly separated from the first conveying belt 11 or enters the second conveying belt 12, and the bottle jamming is prevented.

[0038] Further, in the embodiment, the material blocking assembly is arranged between the first conveying belt 11 and the second conveying belt 12, and is used to intercept the bottles conveyed on the first conveying belt 11 and uniformly convey the bottles above the cylinder 3.

[0039] Specifically, the material blocking assembly comprises two side plates 13, first air cylinders 14 and a blocking piece. The two side plates 13 are fixed on the two side surfaces of the first conveying belt 11 and the second conveying belt 12, the two first air cylinders 14 are fixed on the side plates 13 and located above the first conveying belt 11, and the output ends of the first air cylinders 14 are arranged towards the second conveying belt 12, and the blocking piece is arranged on the output end of the first air cylinder 14. The blocking piece blocks the bottle below, and the bottle is conveyed to the top of the cylinder 3 by the pushing of the first air cylinder 14.

[0040] Specifically, the material blocking assembly comprises two side plates 13, first air cylinders 14 and a blocking piece. The two side plates 13 are fixed on the two side surfaces of the first conveying belt 11 and the second conveying belt 12, the two first air cylinders 14 are fixed on the side plates 13 and located above the first conveying belt 11, and the output ends of the first air cylinders 14 are arranged towards the second conveying belt 12, and the blocking piece is arranged on the output end of the first air cylinder 14. The blocking piece blocks the bottle below, and the bottle is conveyed to the top of the cylinder 3 by the pushing of the first air cylinder 14.

[0041] Further, a plurality of first baffles 18 are arranged side by side on the front side blocking beam 17; two adjacent first baffles 18 are arranged outwardly inclined, so that the clamping space formed by the inner side is trumpet-shaped. A plurality of second baffles 19 are arranged side by side on the rear side blocking beam 17, and two adjacent second baffles 19 are arranged in parallel. The clamping space is formed between two adjacent first baffles 18 and second baffles 19. It should be noted that the clamping space formed between two adjacent second baffles 19 corresponds to each cylinder body 3 one by one.

[0042] When the bottle body approaches the front side blocking beam 17, the first baffle 18 changes the path of the bottle body, and after the front side second cylinder 16 rises, the bottle body continues to advance and enters between the two second baffles 19, so as to ensure that it can be pushed by the first cylinder 14 to above the cylinder body 3.

[0043] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
