DETAILED DESCRIPTION

[0036] The present invention will be further described below based on specific implementation methods.

[0037] like Figure 1-17 The capping device shown comprises a feeding mechanism 3, a cap feeding track 15 and a bottle pressing mechanism 5. The feeding mechanism comprises a feeding port 6 and a hopper 10. The bottle pressing mechanism 5 comprises a capping cylinder 17 and a bottle cap guide assembly 18. The capping cylinder 17 is arranged above the bottle cap guide assembly 18. The bottom outlet of the hopper 10 is connected to the upper end of the cap feeding track 15. There are multiple hoppers 10. In this embodiment, the bottom outlet of the hopper 10 is connected to the upper end of the cap feeding track 15 through a feeding tray 12. There are four hoppers 10. A push plate 9 is arranged on one side of the hopper 10. Scraper belts 7 are arranged at both ends of the push plate 9. The push plate 9 is also connected to a push plate cylinder 8. A kicking wheel 14 is arranged above the upper end of the cap feeding track 15. The lower end of the cap feeding track 15 is connected to the bottle cap guide assembly 18. The cap feeding track 15 is an arc-shaped or side U-shaped track. In this embodiment, a side U-shaped track is adopted. The feeding mechanism 3 further includes a feeding port 6 and a scraper belt 7, and the scraper belt 7 is connected to a driving motor for driving the scraper belt 7 to intermittently move. Figure 3-4As shown, the scrapers on the scraper belt 7 are grouped in pairs, and the space between each group of scrapers becomes a workstation. The workstation below the feed port 6 is the first workstation. In this embodiment, there are five workstations and four silos 10. Among them, there is no silo corresponding to the first workstation, and the other four workstations each correspond to a silo 10. Each hopper 10 is the same size, and the width of each workstation is equal. The scraper belt 7 periodically intermittently moves, and the distance of each intermittent movement is equal to the distance between the center lines of two adjacent workstations. The position of the scraper after each intermittent movement corresponds to the position of the hopper 10 one by one. An electromagnetic vibrator 11 is connected to the bottom of the feeding tray 12, which can promote the bottle caps 16 to enter the cap feeding track 15 faster. A brush roller 13 is provided on the feeding tray 12.

[0038] The bottle cap guide assembly 18 includes a guide block 19, a floating sheet 20, a spring 21 and a side plate 22. A limit hole 4 is provided on the side wall of the guide block 19. The size of the floating sheet 20 matches the limit hole 4. A guide rod 1 is provided on the floating sheet 20. The guide rod 1 passes through the through hole on the side plate 22. The spring 21 is sleeved on the guide rod 1, one end of which is stopped on the floating sheet 20, and the other end is stopped on the inner wall of the side plate 22. The side plate 22 is fixedly set on the side wall of the guide block 19.

[0039] During operation, bottle caps are poured to the first station on the scraper belt 7 through the feed port 6. The drive motor controlled by the encoder makes the scraper belt 7 move intermittently periodically. Each time the scraper belt 7 moves, the bottle caps are delivered to the next station. When the scraper belt 7 moves intermittently until each station is full of bottle caps, the push plate cylinder 8 is activated to push the push plate 9 forward, and the bottle caps located on the front side of each push plate 9 are pushed into the corresponding hopper 10.

[0040] like Figure 5 As shown, under the vibration of the electromagnetic vibrator 11, the bottle cap 16 is accelerated to be sent into the cap feeding track 15, as shown in FIG. Figure 6 As shown, the brush roller 13 rotates counterclockwise to level the bottle caps 16 in the upright state, with the cap opening facing upward or downward; at the same time, the kicking wheel 14 rotates counterclockwise, and when the bottle cap reaches the upper end of the cap feeding track 15, if the cap opening faces upward, it can pass through the kicking wheel 14, and if the cap opening faces downward, it is kicked back to the feeding tray 12 by the kicking wheel 14. The working principle of the kicking wheel 14 is as follows Fig. 9 shown.

[0041] When the bottle cap 16 is conveyed by the cap delivery track 15 and reaches the bottle pressing mechanism 5, the cap opening direction of the bottle cap is reversed. Figure 7 As shown, the bottle cap 16 moves from position 1 to position 2, and the direction of the bottle cap opening changes from upward to downward, and finally falls into the guide block 19.

[0042] When the bottle cap 16 enters the guide block 19, it is limited by the floating pieces 20 on both sides. Since the side plates 22 are fastened and fixed on both sides of the guide block 19, the guide rod 1 on the floating piece 20 is covered with the spring 21 and passes through the through hole on the side plate 22. Under the action of the spring 21, the floating piece 20 plays a role in limiting and clamping the bottle cap 16. When the capping cylinder 17 moves downward and presses the bottle cap 16 downward, the floating piece 20 is squeezed outward, the spring 21 is compressed, the floating piece 20 moves outward, enters the limiting hole 4, and the guide rod 1 further passes through the through hole; at the same time, the bottle cap 16 is tightly pressed on the vial 2. After the pressing is completed, the capping cylinder 17 moves upward and leaves the guide block 19. The floating piece 20 enters the guide block 19 again under the action of the spring 21 and returns to the position before the capping action; at the same time, the vial 2 with the bottle cap 16 pressed leaves and enters the subsequent process of the assembly line.

[0044] The above is only a preferred embodiment of the present invention, but it is not limited to the above specific embodiments. For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept, which all belong to the protection scope of the present invention.
