DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3 A PP bottle oral liquid cap grabbing and capping device includes a connecting sleeve 1, a pressure spring 2, a directional sleeve 3, a guide sleeve 4, a capping head 5 and a ball pushing assembly. The lower end of the connecting sleeve 1 is fixedly connected to the upper end of the directional sleeve 3, one end of the guide sleeve 4 is fixedly installed inside the directional sleeve 3, the pressure spring 2 is arranged in the directional sleeve 3, the ball pushing assembly is connected to the pressure spring 2, the upper end of the connecting sleeve 1 is connected to an external device, and the capping head 5 is a part for grabbing the oral liquid bottle cap.

[0021] The lower end of the guide sleeve 4 is symmetrically fixed with mounting blocks 6, and a movable groove is provided on the lower surface of the two mounting blocks 6. A movable block 7 is horizontally slidably installed in the two movable grooves through an adjusting component. An L-shaped card slot 8 is provided on the lower surface of the two movable blocks 7. An L-shaped card slot 8 is symmetrically fixed on the upper end of the capping head 5. The two card blocks 9 are respectively inserted in the two card slots 8. The adjusting component includes a threaded rod 13 horizontally rotatably installed in the movable groove and an adjusting block 14 fixedly installed on one end of the threaded rod 13 extending out of the movable groove. The movable block 7 is threadedly sleeved on the threaded rod 13, and the side wall of the movable block 7 is in sliding contact with the inner wall of the movable groove.

[0022] When it is necessary to replace the capping head 5 of a different model, the threaded rod 13 is driven to rotate by rotating the adjusting block 14. Under the action of the threaded rod 13, the moving block 7 is driven to move away from the guide sleeve 4 until one end of the clamping block 9 is moved out of one end of the clamping groove 8. The lock between the clamping block 9 and the moving block 7 is released, and the capping head 5 can be removed from the guide sleeve 4.

[0023] When installing a new screw capping head 5, move the moving block 7 so that the slot 8 opened by the moving block 7 corresponds to the two slots 8 on the screw capping head 5, insert the two slots 8 into the two slots 8 respectively, and then drive the two moving blocks 7 closer to each other, snap the slots 8 together to complete the installation of the screw capping head 5. Different types of screw capping heads 5 can be replaced according to the size of the oral liquid bottle cap, so there is no need to replace different equipment, which is highly practical.

[0024] A protective cover 15 is fixedly mounted on the lower surface of the two mounting blocks 6. The protective cover 15 is conical in shape. The screw capping head 5 is located below the protective cover 15. The diameter of the protective cover 15 is larger than the diameter of the lower end of the guide sleeve 4, which can conveniently and promptly cover the lower end of the guide sleeve 4 and prevent the liquid in the bottle from splashing out and affecting other components.

[0025] The ball top assembly includes a rolling bearing 10, a movable sleeve 11 and a core shaft 12. The rolling bearing 10 is rotatably sleeved on the core shaft 12. The rolling bearing 10 is rotatably installed on the connecting sleeve 1. The core shaft 12 is inserted into the connecting sleeve 1, the directional sleeve 3 and the guide sleeve 4 in sequence. The movable sleeve 11 is fixedly sleeved on the core shaft 12. The movable sleeve 11 is slidably arranged in the guide sleeve 4. The top pressure spring 2 is sleeved on the core shaft 12 and its two ends are fixedly connected to the connecting sleeve 1 and the movable sleeve 11 respectively. The lower end of the connecting sleeve 1 is equipped with an upper magnetic steel seat 16, the upper end of the directional sleeve 3 is equipped with a lower magnetic steel seat 17, and the lower magnetic steel seat 18 is installed. A telescopic spring 18 is installed between the steel seat 17 and the guide sleeve 4. The external device moves the screw capping head 5 above the bottle cap through the connecting sleeve 1, the directional sleeve 3 and the guide sleeve 4, and then clamps the bottle cap on the screw capping head 5. The connecting sleeve 1 is then rotated to drive the screw capping head 5 to rotate through the directional sleeve 3 and the guide sleeve 4, thereby tightening the bottle cap on the oral liquid bottle and pushing the core shaft 12 downward. The top pressure spring 2 is compressed, and the lower end of the core shaft 12 contacts the bottle cap and fixes the bottle cap from the screw capping head 5. The setting of the movable sleeve 11 can ensure that the core shaft 12 moves vertically up and down in the guide sleeve 4.

[0026] An oil pan 19 is fixedly mounted on the upper end of the connecting sleeve 1. An adjustment pad is installed in the oil pan 19. When the external device is working, the oil pan 19 can catch the oil leaked from the external device to prevent the oil from falling on other components and affecting the operation of other components.

[0027] In the present invention, when it is necessary to replace the capping head 5 of a different model, the movable block 7 is driven by the adjustment component to move away from the guide sleeve 4 until one end of the clamping block 9 is moved out of one end of the clamping slot 8, and the lock between the clamping block 9 and the movable block 7 is released, and the capping head 5 can be removed from the guide sleeve 4.

[0028] When installing a new screw capping head 5, move the moving block 7 so that the slot 8 opened by the moving block 7 corresponds to the two slots 8 on the screw capping head 5, insert the two slots 8 into the two slots 8 respectively, and then drive the two moving blocks 7 closer to each other, snap the slots 8 together to complete the installation of the screw capping head 5. Different types of screw capping heads 5 can be replaced according to the size of the oral liquid bottle cap, so there is no need to replace different equipment, which is highly practical.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
