[0002] In automatic bottling machinery and equipment, after the packaging bottle is filled, the capping machine automatically screws on the cap at the bottle mouth, and the cap is transported through the conveying chute. In the conveying chute for caps, when transporting the correct cap, it can be screwed on by the anti-tightening capping machine; when transporting the reverse cap, it cannot be screwed on at the bottle mouth by the anti-tightening capping machine, and at the same time, it will cause the corresponding capping mechanism to jam, resulting in serious damage to the equipment. Therefore, in view of these current situations, there is an urgent need to develop a cap rejection and reverse prevention mechanism to meet the actual use requirements. Content of the Utility Model

Detailed implementation manner

[0021] For the convenience of understanding by those skilled in the art, the following combines embodiments with the accompanying drawings to further illustrate the present utility model. The content mentioned in the implementation manner does not limit the present utility model. The following describes the present utility model in detail with reference to the accompanying drawings.

[0022] Please refer to Figures 1-5 , a bottle cap rejection and reverse mechanism in its specific implementation, includes a transportation channel 1, a lifting and rejecting member 4, a limiting wheel 6 and a mounting bracket 3. An ejection opening 14 is provided on the top surface of the middle part of the transportation channel 1. A plurality of movable cover bodies 2 are provided inside the transportation channel 1. One end surface of the cover body 2 is a cavity 21 that is concave inward. The lifting and rejecting member 4 is arranged at the bottom of the transportation channel 1 through a driving member 5 and is located below the ejection opening 14. One side of the driving member 5 is a vertically arranged extending fork arm 42. The extending fork arm 42 can extend upward into the transportation channel 1 through the driving member 5. A distance measuring sensor 8 is also provided between the driving member 5 and the lifting and rejecting member 4. The distance measuring sensor 8 senses the cavity 21 into the transportation channel 1. The limiting wheel 6 is arranged in front of the lifting and rejecting member 4. One end of the mounting bracket 3 is two horizontally arranged support arms 32. The limiting wheel 6 is rotatably arranged between the two support arms 32. The edge of the limiting wheel 6 is several outwardly protruding limiting convex columns 62. The limiting convex columns 62 extend into the cavity 21 inside the transportation channel 1.

[0023] Specifically, the driving member 5 is composed of a linear cylinder. The bottom of the linear cylinder is a push rod 51 that can move up and down. The other side of the driving member 5 is a horizontally arranged mounting part 41. The driving member 5 is fixedly connected to the end of the push rod 51 through the mounting part 41. The other end of the mounting bracket 3 is a fixing part 31. The top surface of the linear cylinder is fixedly connected to the bottom of the fixing part 31.

[0024] Specifically, a rotation through hole 321 is provided at the end of the support arm 32. Horizontal extending rotating pins 61 are provided on both sides of the limiting wheel 6. The limiting wheel 6 is rotatably inserted into the rotation through hole 321 through the rotating pins 61. Several limiting convex columns 62 are arranged in a circumferential array along the rotating pins 61 as the center, which can effectively ensure that under the limiting action of the limiting convex columns 62, the transportation distance between each cover body 2 remains the same interval width.

[0025] The specific transportation channel 1 is composed of a number of transportation rods 11 and a number of block fixing frames 12. The fixing frame 12 is a hollow structure in the shape of a frame. The middle parts of a number of transportation rods 11 are inserted and fixed along the edge of the fixing frame 12, and there is a clearance gap 13 between two adjacent transportation rods 11.

[0026] In a preferred solution, a collection box 7 is provided on the top end surface in the middle of the transportation channel 1. One end of the collection box 7 is provided with a collection opening 71, and the collection opening 71 is located at one end of the removal opening 14. The cover body 2 removed upward by the lifting removal member 4 is limited to move to one side of the collection opening 71 by the limit convex column 62, effectively moving the reverse cover body 2 into the interior of the collection box 7.

[0027] Among them, in a preferred solution, the distance measuring sensor 8 is composed of an infrared sensor. The infrared sensor is used to measure the distance of the end surface of the cover body 2. Through the optical emission principle of the infrared sensor, the infrared ray passes through the clearance gap 13 and irradiates the end of the cover body 2. According to the duration of the infrared ray reflection, the distance between the end surface of the cover body 2 and the distance measuring sensor 8 can be judged, so as to judge the front and back of the cover body 2 in the transportation channel 1.

[0028] The working process of a bottle cap removal and reversal mechanism: The bottle cap moves forward inside the transportation channel 1 and passes below the removal opening 14 in turn. When the cover body 2 with the cavity 21 facing upward passes through the distance measuring sensor 8, the distance between the end surface of the cover body 2 and the distance measuring sensor 8 can be judged according to the duration of the infrared ray reflection, so as to judge the front and back of the cover body 2 in the transportation channel 1. At this time, the linear cylinder drives the lifting removal member 4 to move upward by a certain distance, and the extending fork arm 42 abuts against the edge of the cover body 2, lifting the cover body 2 by a small distance. At the same time, the rotating limit wheel 6 can abut one of the limit convex columns 62 against the bottom end surface of the cover body 2, and gradually lift the cover body 2 above the removal opening 14 along the swing of the limit convex column 62. Finally, the limit convex column 62 is limited to move to one side of the collection opening 71, effectively moving the reverse cover body 2 into the interior of the collection box 7 to complete the process of removing and reversing the bottle cap.

[0029] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention is disclosed above with a preferred embodiment, it is not intended to limit the present invention.
