Examples

As shown in fig. 1-3, the cap screwing machine of the present embodiment includes a pair of cap screwing devices arranged in mirror symmetry; the cap screwing device comprises an extrusion device, a rotating wheel device arranged above the extrusion device, and a driving device used for driving the extrusion device and the rotating wheel device to move horizontally; the extruding device is used for extruding the lug boss 42 at the bottle neck; the rotating wheel device is used for rotating the sealing cover 41. Specifically, the conventional cap screwing machine mainly clamps the bottle body 40 and then screws the sealing cap 41, which easily causes unstable fixation of the bottle body 40 and spills out the liquid in the bottle for some bottles with the concave-convex structure of the bottle body 40 and very thin wall surface, while the embodiment clamps the boss 42 at the bottle neck by a pair of pressing devices in a pair of cap screwing devices, and then uses a pair of rotating wheel devices to rotate and screw the sealing cap 41. This is because the boss 42 at the neck of the bottle has a larger thickness and a higher strength than the body 40, and is less likely to be deformed when pressed. Thus, the bottle body 40 is fixed by directly clamping the boss 42, so that the bottle body 40 can be effectively prevented from being squeezed, and particularly, for some beverage bottles with extremely thin bottle bodies 40, the situation that liquid in the bottles is spilled in the process of squeezing the bottle bodies 40 can be effectively avoided. The mechanism for fixing body 40 can also be omitted to some extent.

The extrusion device in the embodiment comprises an arc-shaped extrusion plate 10 and an extrusion rod 11 fixedly connected with the extrusion plate 10; the curvature of the compression plate 10 is the same as that of the boss 42. One surface of the extrusion plate 10 close to the boss 42 is provided with a groove; the groove fits the edge of the boss 42. The inner wall of the groove is provided with an anti-skid layer. Specifically, the groove matched with the boss 42 is formed in the arc-shaped extrusion plate 10, and the anti-slip layer arranged in the groove can effectively enable the extrusion plate 10 to be attached to the boss 42 and can effectively increase the friction force between the extrusion plate 10 and the boss 42. The relative sliding between the two is avoided, and the scratch of the extrusion plate 10 on the boss 42 and the influence on the appearance can also be effectively avoided.

The extrusion device in this embodiment further includes a sleeve 12 sleeved on one end of the extrusion rod 11 far away from the extrusion plate 10, a spring 13 sleeved outside the extrusion rod 11, and a pair of annular fixing plates 14; one fixing plate 14 is fixedly arranged on the outer wall of the sleeve 12, and the other fixing plate 14 is fixedly arranged on the outer wall of the extrusion rod 11; one end of the sleeve 12 far away from the extrusion rod 11 is connected with a driving device; two ends of the spring 13 are respectively fixedly connected with a pair of fixing plates 14. Specifically, when the driving device pushes the extrusion device and the rotating wheel device to be close to the sealing cover 41, the extrusion plate 10 firstly contacts the boss 42, and along with the operation of the driving device, under the action of the spring 13, the interaction between the extrusion plate 10 and the boss 42 is stronger and stronger until the extrusion plate 10 can completely fix the boss 42, namely, the bottle body 40 is fixed, at this time, the rotating wheel device contacts the sealing cover 41 again, and then the sealing cover 41 is rotated to be screwed down.

The rotating wheel device in this embodiment includes a horizontally disposed spiral cover wheel 20 and a power mechanism for driving the spiral cover wheel 20 to rotate. The power mechanism comprises a motor 21; the output shaft of the motor 21 is fixedly connected with the rotating shaft of the cap screwing wheel 20; the motor 21 is fixedly connected with the driving device through a connecting block 23. The outer wall of the cover screwing wheel 20 is provided with an anti-skid layer. Specifically, the driving device drives the cap rotating wheel 20 to contact and press the sealing cap 41, and the motor 21 drives the cap rotating wheel 20 to rotate, so that the sealing cap 41 is rotated and screwed by friction between the cap rotating wheel 20 and the sealing cap 41. The anti-slip layer can effectively prevent the rotating wheel from slipping with the sealing cover 41.

The rotating wheel device in the embodiment further comprises a supporting rod 22 and a bearing seat arranged at one end of the supporting rod 22; the motor 21 is arranged above the cap screwing wheel 20, and the support rod 22 is arranged below the cap screwing wheel 20; one end of the support rod 22 far away from the bearing block is fixedly connected with the connecting block 23; one end of the rotating shaft of the cap screwing wheel 20, which is far away from the motor 21, is arranged in the bearing seat. Specifically, the support bar 22 mainly serves to support the rotation wheel, thereby ensuring stable rotation thereof.

The driving device in the present embodiment includes an electric telescopic cylinder 30 disposed horizontally; the telescopic rod of the electric telescopic cylinder 30 is fixedly connected with the connecting block 23. Specifically, since the driving device only needs to drive the extruding device and the rotating wheel device to move a small distance, a small pneumatic telescopic cylinder or a small hydraulic cylinder can be used.

In summary, the capping machine of the present embodiment clamps the boss 42 of the bottle neck by a pair of pressing devices of a pair of capping devices, and then rotates and screws the sealing cap 41 by a pair of rotating wheel devices. Thus, the bottle body 40 is fixed by directly clamping the boss 42, so that the bottle body 40 can be effectively prevented from being squeezed, and particularly, for some beverage bottles with extremely thin bottle bodies 40, the situation that liquid in the bottles is spilled in the process of squeezing the bottle bodies 40 can be effectively avoided. The mechanism for fixing body 40 can also be omitted to some extent.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
