Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically to a sealing performance testing device for bottle caps. Background Technology

[0002] Bottle caps are devices used to seal bottle openings. They achieve leak-proof and anti-theft functions through structures such as threads, sealing rings, and side sealing rings. PE pull-ring caps, also known as polyethylene pull-ring sealing caps, are environmentally friendly bottle caps widely used in food packaging. Made of high-density polyethylene, they have excellent oil resistance and sealing properties, effectively blocking air and moisture and extending the liquid's storage time. Due to their one-click tear-off design, they are convenient and hygienic to use and are commonly used in packaging salad oil, soy sauce, vinegar, wine, etc.

[0003] The PE pull ring cap is divided into two parts. After assembly, the sealing condition of the upper and lower parts cannot be directly observed by the workers, which affects the test results and needs to be improved. Therefore, a sealing test device for wine bottle caps is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sealing performance testing device for wine bottle caps, which has advantages such as good testing effect and solves the problem that workers cannot directly see the sealing condition of the upper and lower parts by visual inspection, thus affecting the testing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sealing performance testing device for wine bottle caps, comprising a base plate, a rotating mechanism and a limiting mechanism connected to the top of the base plate, a connecting plate fixedly mounted on the top of the base plate, a testing mechanism connected to the connecting plate, an air blowing mechanism suspended above the rotating mechanism, and two conveyor belts placed on the top of the base plate.

[0006] Furthermore, the rotating mechanism includes a first motor, which is fixedly connected to the top of the base plate. A rotating platform is fixedly mounted on the top of the first motor. A pad and a rotating plate are fixedly mounted on the top of the rotating platform. Multiple annular grooves are formed on the edge of the rotating plate.

[0007] Furthermore, the limiting mechanism includes multiple vertical rods, all of which are fixedly connected to the top of the base plate. A limiting plate is fixedly installed on the top of the multiple vertical rods, and the limiting plate is located outside the rotary table.

[0008] Furthermore, the top of the limiting plate is provided with a feeding groove and a discharging groove, which are symmetrically distributed.

[0009] Furthermore, the detection mechanism includes an electric push rod, which is fixedly connected to the top of the connecting plate. The output end of the electric push rod passes through the connecting plate and is fixedly installed with a connecting cylinder. A connecting block is fixedly installed at the bottom of the connecting cylinder. An air inlet pipe is inserted into the top of the connecting block and extends through and to the outside of the connecting cylinder. An air inlet hole communicating with the air inlet pipe is opened inside the connecting block. A pressure sensor and a sealing ring are fixedly installed at the bottom of the connecting block.

[0010] Furthermore, the connecting cylinder has a through hole inside, which matches the air intake pipe.

[0011] Furthermore, the air blowing mechanism includes an air blowing pipe, the bottom of which is connected to a connecting pipe, and the outside of the connecting pipe is connected to two branch pipes, each of which has a valve fixedly installed inside.

[0012] Furthermore, both conveyor belts are located on the same side of the discharge trough, and the tops of both conveyor belts are flush with the top of the discharge trough.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This sealing test device for bottle caps comprises a base plate, a rotating mechanism, a limiting mechanism, a connecting plate, a testing mechanism, an air blowing mechanism, and a conveyor belt. The operator first passes the assembled PE pull-ring cap through the limiting mechanism and places it on top of the rotating mechanism. Then, the rotating mechanism moves the assembled PE pull-ring cap directly below the testing mechanism. The testing mechanism then performs a sealing test on the assembled PE pull-ring cap. The rotating mechanism then moves the next assembled PE pull-ring cap directly below the testing mechanism. Finally, the air blowing mechanism blows the tested PE pull-ring caps onto the conveyor belt. Two conveyor belts transport qualified and unqualified PE pull-ring caps respectively. This eliminates the need for visual inspection of the upper and lower parts of the seal, improving the testing efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 The sealing detection device for bottle caps in this embodiment includes a base plate 1. A rotating mechanism 2 and a limiting mechanism 3 are connected to the top of the base plate 1. A connecting plate 4 is fixedly installed on the top of the base plate 1. A detection mechanism 5 is connected to the connecting plate 4. An air blowing mechanism 6 is suspended above the rotating mechanism 2. Two conveyor belts 7 are placed on the top of the base plate 1.

[0018] Specifically, the staff first passes the assembled PE pull ring cap through the limiting mechanism 3 and places it on top of the rotating mechanism 2. Then, the rotating mechanism 2 is used to move the assembled PE pull ring cap directly below the detection mechanism 5. The detection mechanism 5 then performs a sealing test on the assembled PE pull ring cap. The rotating mechanism 2 is then used to move the next assembled PE pull ring cap directly below the detection mechanism 5. Finally, the blowing mechanism 6 blows the tested PE pull ring cap onto the conveyor belt 7. The two conveyor belts 7 respectively transport qualified and unqualified PE pull ring caps. There is no need to visually inspect the sealing of the upper and lower halves, which improves the detection effect.

[0019] In this embodiment, the rotating mechanism 2 includes a first motor 21, which is fixedly connected to the top of the base plate 1. A rotating platform 22 is fixedly installed on the top of the first motor 21. A pad 23 and a rotating plate 24 are fixedly installed on the top of the rotating platform 22. The pad 23 is made of rubber. The rotating plate 24 has twelve annular grooves on its edge, which are evenly and equidistantly distributed in annular shape.

[0020] Specifically, the lower half of the PE pull ring cover is placed on top of the pad 23 and located inside the annular groove. By turning on the first motor 21, the first motor 21 drives the rotating table 22, the pad 23, the rotating plate 24 and the lower half of the PE pull ring cover to rotate.

[0021] In this embodiment, the limiting mechanism 3 includes multiple vertical rods 31, all of which are fixedly connected to the top of the base plate 1. A limiting plate 32 is fixedly installed on the top of the multiple vertical rods 31. The limiting plate 32 is located outside the rotating table 22. The top of the limiting plate 32 is provided with a loading groove and a unloading groove, which are symmetrically distributed.

[0022] Specifically, the width of the feeding trough is greater than the diameter of the lower half of the PE pull ring cover. The conveyor belt transports the lower half of the PE pull ring cover, which moves through the groove of the feeding trough and into the annular groove by inertia.

[0023] In this embodiment, the detection mechanism 5 includes an electric push rod 51, which is fixedly connected to the top of the connecting plate 4. The output end of the electric push rod 51 passes through the connecting plate 4 and is fixedly installed with a connecting cylinder 52. A connecting block 53 is fixedly installed at the bottom of the connecting cylinder 52. An air inlet pipe 54 is inserted into the top of the connecting block 53, passing through and extending to the outside of the connecting cylinder 52. A through hole is opened inside the connecting cylinder 52, which matches the air inlet pipe 54. An air inlet hole communicating with the air inlet pipe 54 is opened inside the connecting block 53. A pressure sensor 55 and a sealing ring 56 are fixedly installed at the bottom of the connecting block 53.

[0024] Specifically, by activating the electric push rod 51, the electric push rod 51 drives the connecting cylinder 52, connecting block 53, air inlet pipe 54, pressure sensor 55 and sealing ring 56 to move downward, so that the sealing ring 56 contacts the top of the upper half of the PE pull ring cover. By connecting the air inlet pipe 54 to the first air pump, the first air pump is turned on, and a certain amount of air is blown out through the air inlet pipe 54 and the air inlet hole. The pressure sensor 55 detects the pressure change over a certain period of time. If there is no leakage, it is qualified; if there is leakage, it is unqualified.

[0025] In this embodiment, the air blowing mechanism 6 includes an air blowing pipe 61, the bottom of which is connected to a connecting pipe 62, and the outside of the connecting pipe 62 is connected to two branch pipes 63, each of which has a valve fixedly installed inside.

[0026] Specifically, by connecting the air blowing pipe 61 to the second air pump and turning on the second air pump, the air is blown out through the air blowing pipe 61, the connecting pipe 62 and the two branch pipes 63. The blowing situation can be controlled by closing the valve.

[0027] In this embodiment, both conveyor belts 7 are located on the same side of the feeding trough, and the tops of both conveyor belts 7 are flush with the top of the feeding trough.

[0028] Specifically, one conveyor belt 7 is used to transport qualified PE pull ring caps, and the other conveyor belt 7 is used to transport unqualified PE pull ring caps.

[0029] The working principle of the above embodiments is as follows: A worker first passes the assembled PE pull-tab cover through the feeding trough and places it on the top of the rotating table 22, then starts the first motor 21. The first motor 21 drives the rotating table 22, the backing plate 23, the rotating plate 24 and the assembled PE pull-tab cover to rotate to directly below the connecting block 53, then starts the electric push rod 51. The electric push rod 51 drives the connecting cylinder 52, the connecting block 53, the air inlet pipe 54, the pressure sensor 55 and the sealing ring 56 to move downward, so that the sealing ring 56 contacts the top of the upper half of the PE pull-tab cover. The first air pump is started, and a certain amount of air is blown out through the air inlet pipe 54 and the air inlet hole. The pressure sensor 55 detects the pressure change within a certain period of time. No leakage indicates a qualified product, while leakage indicates an unqualified product. Then the first motor 21 is started to move the next assembled PE pull-tab cover to directly below the connecting block 53. Finally, the second air pump is started, and air is blown out through the air blowing pipe 61, the connecting pipe 62 and the two branch pipes 63. Closing the valve can control the air blowing condition, and blow the detected PE pull-tab covers to the conveyor belts 7. The two conveyor belts 7 respectively transmit the qualified PE pull-tab covers and the unqualified PE pull-tab covers. There is no need to visually detect the sealing performance of the upper half and the lower half, which improves the detection effect.
