[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3 As shown, a locking device includes a bracket 1, a first lifting drive mechanism 2 and a locking head 3 mounted on the bracket 1. The first lifting drive mechanism 2 connects a first lifting shaft 4 and a second lifting shaft 5. A guide sleeve 21 is provided on the bracket 1. The first lifting shaft 4 and the second lifting shaft 5 pass through the guide sleeve 21 and are connected to a first mounting base 6. A pressure ring 7 abuts against the outside of the locking head 3. The locking head 3 is located between the first lifting shaft 4 and the second lifting shaft 5. A first adjusting member 8 is provided above the locking head 3. The bracket 1 is connected to the second lifting drive mechanism. 18. The second lifting drive mechanism 18 drives the bracket 1 to lift, causing the locking head 3 to descend. Then, the first lifting drive mechanism 2 drives the first lifting shaft 4 and the second lifting shaft 5 to descend within the guide sleeve 21. The guide sleeve 21 guides the locking head, ensuring the alignment of the cover and the container when locking. The pressure ring 7, which is abutting against the outside of the locking head 3, descends to lock the locking head 3. The locking head 3 is located between the first lifting shaft 4 and the second lifting shaft 5. There is a large space above the locking head 3 for adjusting the first adjusting member 8. The overall layout is reasonable and convenient for adjustment.

[0025] The bracket 1 is equipped with multiple sets of first lifting drive mechanisms 2 and locking heads 3. The adjacent first lifting drive mechanisms 2 are arranged at different heights, which is reasonable and convenient for installation and adjustment.

[0026] Below the locking head 3 is a container positioning mechanism 9. The pump head to be locked is placed on the container and conveyed to the container positioning mechanism 9. Then, the container is positioned by the container positioning mechanism 9, so that the locking head 3 can descend to position and lock the pump head.

[0027] The locking head 3 includes a second mounting base 10, a connecting shaft 12 is provided inside the second mounting base 10, the bottom end of the connecting shaft 12 is connected to the pressure head 19 through a second adjusting member 13, a circular grid 11 is sleeved on the outside of the connecting shaft 12, the pressure head 19 is disposed inside the circular grid 11, and an elastic member 14 is provided at the top end of the connecting shaft 12. The elastic member 14 abuts against the connecting shaft 12 and the second mounting base 10 through a first adjusting member 8. The pre-pressure of the elastic member 14 is adjusted by adjusting the first adjusting member 8, and the height between the pressure head 19 and the circular grid 11 is adjusted by adjusting the second adjusting member 13, thereby reducing the impact of processing errors on the capping and locking processes.

[0028] The pressure ring 7 abuts against the outside of the circular grid 11. The first lifting drive mechanism 2 drives the pressure ring 7 to move along the outer circumference of the circular grid 11, causing the circular grid 11 to retract and lock the cover. The second mounting base 10 is provided with a limiting groove 15. A limiting shaft 16 passes through the connecting shaft 12 and is inserted into the limiting groove 15. The pressure ring 7 is a ceramic ring. The material of the circular grid 11 is spring steel. The elastic element 14 is set in the second mounting base 10. The first adjusting element 8 is set on the top of the first mounting base 6. The first adjusting element 8 is used to adjust the preload of the elastic element 14. The circular grid 11 is fixedly connected to the connecting shaft 12 by the locking element 17.

[0029] The container positioning mechanism 9 includes a first positioning block 22 and a second positioning block 23 arranged opposite to each other. The first positioning block 22 is disposed on a first slider 24. A first roller 25 is sleeved inside the first slider 24. The first roller 25 is connected to a first eccentric block 26. The first eccentric block 26 is connected to one end of a first drive shaft 27. The first slider 24 is slidably connected to a slide rail 28. The second positioning block 23 is disposed on a second slider 29. A second roller 30 is sleeved inside the second slider 29. The second roller 30 is connected to a second eccentric block 31. The second eccentric block 31 is connected to a second drive shaft 32. The second slider 29 is slidably connected to the slide rail 28. A first synchronous pulley 33 is sleeved on the first drive shaft 27. The first synchronous pulley 33 is connected to a second synchronous pulley 35 through a synchronous belt 34. The second synchronous pulley 35 is sleeved on the second drive shaft 32. The other end of the first drive shaft 27 is connected to a positioning drive mechanism 36.

[0030] The positioning drive mechanism 36 drives the first transmission shaft 27 to rotate, thereby driving the first synchronous pulley 33, the synchronous belt 34, the second synchronous pulley 35, and the second transmission shaft 32 to rotate. The first eccentric block 26 and the second eccentric block 31, which are respectively connected to the first transmission shaft 27 and the second transmission shaft 32, drive the first roller 25 and the second roller 30 to drive the first slider 24 and the second slider 29 to move on the slide rail 28, so as to realize the first positioning block 22 and the second positioning block 23 moving closer and further apart, thereby clamping or releasing the container.

[0031] After the container and pump head 20 are assembled together at the feeding position, they are conveyed to the pump head locking station, that is, below the cap locking head 3. The second lifting drive mechanism 18 drives the cap locking head 3 to descend, and the top of the pump head 20 enters the circular grid 11 until it contacts the pressure head 19. The elastic element 14 is compressed and rebounds upward. The compression degree of the elastic element 14 is adjusted by the first adjusting element 8. When the pre-pressure of the elastic element 14 is greater, the spring is more difficult to rebound. At this time, the pump head 20 is pressed deeper into the container. Adjusting to a suitable pre-pressure presses the pump head 20 tightly against the container mouth to ensure that the pressure between the bottle mouth and the sealing ring is appropriate. Then, the first lifting drive mechanism 2 drives the pressure ring 7 to descend around the outer periphery of the circular grid 11, causing the circular grid 11 to contract and complete the cap locking.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
