[0036] The specific implementation of the bottle cap conveying unit of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] See attached Figure 1 The bottle cap conveying unit is a part of the sample bottle dispensing and capping system. Its main function is to deliver the bottle caps 2 delivered by the capping machine 1 to the sample bottle at a predetermined time, and then perform operations such as screwing the caps. The capping machine 1 is an existing product. Its principle is to form an opening and arrange the bottle caps 2 downward through the action of centrifugal force and an arc-shaped lever, and deliver them to the conveying rack 4. For example, the "a capping device" disclosed in the invention of announcement number: CN201686461U can achieve the above function.

[0038] The main structures of the cap sorting machine 1 and the cap pressing device 3 are both installed on the workbench, and the conveying frame 4 is used to install the main structures. The conveying frame 4 is provided with a bottle cap conveying channel 5. The output port of the cap sorting machine 1 is connected to the conveying frame 4, and is connected to the bottle cap conveying channel 5. A cover plate 22 is provided at the rear position close to the bottle cap conveying channel 5 to prevent the bottle cap 2 from vibrating and jumping out during the conveying process, thereby affecting normal work.

[0039] The capping device 3 is arranged above the bottle cap conveying channel 5 of the conveying rack. Below the capping device 3 is a sample bottle conveying functional unit, and the capping device 3 presses down the bottle cap 2 conveyed by the capping machine 1 and outputs it to the sample bottle, and sends it to the next process to screw the cap on the sample bottle. This will be explained in detail later.

[0040] See attached Figure 2 , 3 The capping device 3 includes a lifting frame 6 arranged on the conveying frame 4, a pressing rod 7 is arranged on the lifting frame 6, the diameter of the pressing rod 7 is smaller than the diameter of the bottle cap 2, a suction cup 8 is arranged at the lower end of the pressing rod 7, and the suction cup 8 is connected to the vacuum pump through an air pipe. When the pressing rod 7 is pressed down to the bottle cap 2, the suction cup 8 draws a vacuum to suck the bottle cap 2.

[0041] The lifting frame 6 includes a lifting column 9 and a sliding bearing 10 arranged on the conveying frame 4. A conveying motor 11 is arranged below the conveying frame 4. The conveying motor 11 controls the lifting column 9 to rise and fall in the sliding bearing 10. A connecting plate 12 is arranged above the lifting column 9, and the pressing rod 7 is arranged on the connecting plate 12. The conveying motor 11 is connected to the transmission block 14 through a screw rod 13. The lifting column 9 is connected to the transmission block 14. Elastic limiting columns 15 are arranged on the conveying frame 4 above and below the transmission block 14. An adjusting rod 16 is also arranged on the connecting plate 12. The adjusting rod 16 is located at the rear side of the pressing rod 7 and above the position of the second bottle cap 2 from the back in the bottle cap conveying channel 5. A thrust spring is sleeved on the adjusting rod 16, and an elastic head 18 is arranged at the lower end of the adjusting rod 16. When the pressing rod 7 is pressed down, the elastic head 18 of the adjusting rod 16 presses and fixes the bottle cap 2 at the rear downward.

[0042] See attached Figure 3 , 4 The lower end of the bottle cap conveying channel 5 is hollowed out to form a bottle cap drop opening 17. The pressing rod 7 is located just above the drop opening 17. An elastic hinge 19 is arranged at the drop opening 17. The bottle cap 2 with the opening downwards conveyed by the cap sorting machine 1 enters the bottle cap drop opening 17 through the bottle cap conveying channel 5 and is supported by the elastic hinge 19. The lifting frame 6 drives the pressing rod 7 to press down the bottle cap 2. The elastic hinge 19 flips downward and opens under the action of the downward pressure. The bottle cap 2 falls from the bottle cap drop opening 17 into the bottle body opening below. Due to the operation of the suction cup 8 at the lower end of the pressing rod 7, when the pressing rod 7 presses the bottle cap 2 down to below the elastic hinge 19, the suction cup 8 is inflated to release the bottle cap 2, so that the falling height of the bottle cap 2 is shortened, and the bottle cap 2 just falls into the bottle body opening below.

[0043] Three adjusting blocks 20 are arranged at the end of the conveying frame 4 of the bottle cap conveying channel 5, located at both sides and the front. The adjusting blocks 20 adjust the size of the bottle cap drop opening 17 by adjusting screws. One to three pressing plates 21 are arranged on the conveying frame 4 above the drop opening 17. The pressing plates 21 prevent the bottle caps 2 from jumping out.

[0044] In addition, an infrared sensor (not shown in the figure) is arranged on one or more pressing plates 21, and the infrared sensor is connected to the control unit, which can detect the entry status of the bottle caps 2 at the drop port 17 and notify the cap unscrambler 1 to work and whether to continue to convey the bottle caps 2 to the capping device 3.

[0045] See attached Figure 4 , 5 The specific working process is as follows: the bottle cap 2 transmitted by the cap sorting machine 1 is sent to the bottom of the cap pressing device 3 through the bottle cap transmission channel 5. After the lifting frame 6 is started, the lower pressure rod 7 is pressed down, and the suction cup 8 sucks the bottle cap 2 at the front end. At this time, the adjustment rod 16 presses and fixes the second bottle cap 2 to prevent affecting the movement of the bottle cap 2 at the front end. The lower pressure rod 7 continues to press down, and the bottle cap 2 opens the elastic hinge 19 from the bottle cap drop opening 17 and sends it downward. After the bottle cap 2 is sent downward to the predetermined position, the suction cup 8 is released, and the bottle cap 2 falls to the mouth of the sample bottle below. At this time, the elastic hinge 19 is reset. During the working process, according to the feedback of the infrared sensor on the pressing plate 21, the cap sorting machine 1 is controlled to work. When the bottle cap 2 falls, the lifting frame 6 is restored, and the cap sorting machine 1 sends the bottle cap 2. Since the adjustment rod 16 is retracted, the second bottle cap 2 is sent to the front end and waits for the next bottle cap 2 to be output.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
