The bottle cap has the function of maintaining the airtight performance of the contained product, and also has the functions of anti-theft opening and safety. Therefore, it is widely used in bottled products and is a key product for bottle container packaging. At present, most bottle caps use pull-ring and screw-cap structures to achieve opening and closing. When the pull-ring bottle cap is produced and processed, it needs to be moved to a designated production position through a conveyor.

[0003] At present, when a pull-ring bottle cap (such as an in-built pull-ring bottle cap on an oil bottle) is conveyed, although the pull-ring bottle caps can be conveyed in an orderly manner, the sealing of the pull-ring bottle cap on the bottle body should be ensured. At present, there is inconvenience in seal detection when the pull-ring bottle cap is conveyed by means of a conveying device, so the requirements for the quality inspection of the pull-ring bottle cap conveying cannot be met.

Specific embodiments

[0021] The following specific embodiments illustrate the embodiments of the present utility model. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Refer to in combination Figures 1 - 4The utility model provides a pull-ring bottle cap conveyor, including a frame 1, a tray 2 is fixedly connected to the frame 1, a conveying disc 3 is rotatably connected to the tray 2 via a rotating shaft, a rotating device 4 for driving the conveying disc 3 to rotate is fixedly connected to the frame 1, the rotating device 4 can adopt a rotating motor, and the rotating motor can be connected to the rotating shaft of the conveying disc 3 in a driving manner, so that the conveying disc 3 can convey the pull-ring bottle caps to move, and a plurality of bottle cap transport grooves 5 for placing the pull-ring bottle caps are arranged on the conveying disc 3, and the size of the bottle cap transport grooves 5 in the present application can be designed to be slightly larger than the size of the pull-ring bottle caps, and a defective product guide outlet 6 and a conveying discharge port 7 are arranged on the tray 2, and the position of the defective product guide outlet 6 can facilitate the discharge of the pull-ring bottle caps with insufficient sealing, and the conveying discharge port 7 can specify the discharge position of the pull-ring bottle caps after detection.

[0023] A bottle cap guide cage 13 is arranged above the conveyor plate 3, and one end of the bottle cap guide cage 13 corresponds to one of the bottle cap transport slots 5. In the present application, the bottle cap guide cage 13 can be used to guide the pull-ring bottle caps after material sorting into any bottle cap transport slot 5, and the material sorting of the pull-ring bottle caps can be achieved by the existing bottle cap material sorting process.

[0024] A cantilever frame 8 is fixedly connected to the tray 2, and an opening and closing component 9 for opening and closing the defective product outlet 6 is provided on the cantilever frame 8. The opening and closing component 9 can conveniently support the pull-ring bottle cap on the one hand and conveniently discharge the pull-ring bottle cap on the other hand by opening and closing the position of the defective product outlet 6. A telescopic device 10 is fixedly connected to the cantilever frame 8. The telescopic device 10 adopts a telescopic motor. An elastic connecting piece 11 is provided on the telescopic device 10, and a sealing detection mechanism 12 for sealing detection of the pull-ring bottle cap is provided on the elastic connecting piece 11.

[0025] The opening and closing assembly 9 includes a telescopic device 91 fixedly connected to the cantilever frame 8 and a blocking plate 92 fixedly connected to the output end of the telescopic device 91. The blocking plate 92 is slidably connected in the defective product outlet 6, and the blocking plate 92 is in active contact with the bottom of the conveying tray 3. The telescopic device 91 can use a telescopic motor.

[0026] Specifically, when one of the bottle cap transport slots 5 corresponds to the upper position of the defective product outlet 6 and at the same time, the blocking plate 92 is supported at the bottom of the bottle cap transport slot 5, the pull-ring bottle cap in the bottle cap transport slot 5 can be supported by the blocking plate 92 for sealing detection. When the pull-ring bottle cap detects insufficient sealing, the telescopic device 91 can control the blocking plate 92 to move in a straight line to move away from the position of the bottle cap transport slot 5, so that the pull-ring bottle cap supported on the blocking plate 92 can fall off, and the falling position of the pull-ring bottle cap can be collected by a collecting device.

[0027] The elastic connecting member 11 includes a smooth rod 111 fixedly connected to the output end of the telescopic device two 10, a limit ring 112 fixedly connected to the smooth rod 111, and a compression spring 113 movably sleeved on the smooth rod 111. The compression spring 113 is arranged below the limit ring 112.

[0028] The seal detection mechanism 12 includes a detection cylinder 121 slidably connected to the smooth rod 111, a seal pressing plate 122 fixedly connected to the bottom of the detection cylinder 121, a compression piston 123 slidably connected inside the detection cylinder 121, and a barometric pressure sensor 124 fixedly connected to the outer surface of the detection cylinder 121. The smooth rod 111 can be slidably connected to the detection cylinder 121 through a linear bearing. At the same time, the smooth rod 111 extends into the detection cylinder 121.

[0029] The compression piston 123 is fixedly connected to the end of the smooth rod 111 facing away from the telescopic device two 10. The bottom of the detection cylinder 121 is open. An air port is provided on the seal pressing plate 122. The air port facilitates the detection cylinder 121 to communicate with the pull-ring bottle cap through the seal pressing plate 122. The seal pressing plate 122 is in movable contact with the pull-ring bottle cap. The detection end of the barometric pressure sensor 124 extends into the detection cylinder 121.

[0030] The barometric pressure sensor 124 is arranged at the lower side position of the compression piston 123. When the compression piston 123 moves downward to the lowest position, at this time, the compression piston 123 should be higher than the position of the barometric pressure sensor 124. The detection cylinder 121 presses the seal pressing plate 122 on the pull-ring bottle cap. In this way, the bottle cap with the built-in pull ring can be conveniently connected to the detection cylinder 121. By controlling the air pressure and detecting the air pressure inside the detection cylinder 121, the tightness inside the pull-ring bottle cap can be conveniently tested. In this application, the telescopic device one 91, the telescopic device two 10, the rotating motor, and the barometric pressure sensor 124 can all be controlled by a controller. When the pull-ring bottle cap performs a seal detection action, the position state of the pull-ring bottle cap can be monitored through an optoelectronic module. In this way, the mobility of drive control can be improved.

[0031] A telescopic groove 14 is provided on the cantilever frame 8. A slide bar 16 is fixedly connected inside the telescopic groove 14. A slide seat 15 is fixedly connected to the outer surface of the detection cylinder 121. The slide seat 15 extends into the telescopic groove 14 and is slidably connected to the slide bar 16. When the detection cylinder 121 moves up and down, the slide seat 15 can linearly slide on the slide bar 16. In this way, the stability of the seal detection movement of the detection cylinder 121 can be improved.

[0032] When the utility model is in use, the ring-pull bottle caps after material sorting are introduced into the bottle cap transportation groove 5 of the transportation tray 3 through the bottle cap guide cage 13. After the ring-pull bottle caps in the bottle cap transportation groove 5 move to the position below the detection cylinder 121, the piston of the second telescopic device 10 can extend at this time, so as to drive the detection cylinder 121 to move downward and press the sealing pressing plate 122 against the port position of the ring-pull bottle cap. When the sealing pressing plate 122 is pressed against the ring-pull bottle cap, the compression spring 113 is gradually compressed at this time, and the optical rod 111 can be introduced into the detection cylinder 121 and drive the compression piston 123 to compress and slide in the detection cylinder 121, then the compression piston 123 can change the air pressure state in the detection cylinder 121. The external controller can determine the sealing performance of the ring-pull bottle cap by identifying and judging the magnitude of the air pressure data detected by the air pressure sensor 124. When the sealing in the ring-pull bottle cap is insufficient, the first telescopic device 91 can move the blocking plate 92 at this time to export the ring-pull bottle cap through the defective product outlet 6.
