For ease of understanding, the rotary capping mechanism in this embodiment will be described in detail below through a specific application scenario, please refer to Figures 1 to 3:

The rotary capping mechanism 8 includes a translation cylinder 81, an air claw mounting frame 82, a pneumatic gripper 83, an intermittent upper cover part 84, a rotating cylinder 85, a rotating block 86 installed in the rotating cylinder 85, a rotating shaft 87, and a motor 88 , Middle frame 89, first spring 90, first cylinder 91, as shown in Figures 1 and 2. This intermittent loam cake component 84 is installed on the end of the guide rail of last small cover mechanism, comprises pallet 92 and the 4th air cylinder 93, only makes a small cover arrive pallet 92 at every turn by the action of cylinder. The rotary cylinder 85 and the motor 88 are mounted on the middle frame, and the first air cylinder is connected with the middle frame to drive the middle frame to move up and down. The pneumatic gripper is installed on the air claw mounting frame 82, and the translation cylinder is horizontally placed and connected with the air claw mounting frame 82. The pneumatic gripper and the air claw mounting frame 82 can be moved to the top of the pallet or the rotating cylinder under the drive of the translation cylinder. There are sliding keyways 94 and 6 small bosses 95 on the rotating block. The small bosses 95 can play a frictional role when the small cap is tightened to drive the small cap to rotate. When the small cap is tightened, the friction force is insufficient, and the rotating block If it slips, it means that the small cap has been tightened, as shown in Figure 3. There is a bottle cap guide structure 96 at the top of the rotating cylinder, and the outer surface of the small cap can be in contact with the inner surface of the rotating cylinder after the cap falls, which can play the role of a sliding bearing. One end of the rotating shaft is connected to the rotating block through a sliding key, and the other end is connected to the motor using a coupling, and is set in the first spring. The first spring drives the rotating block to cling to the small cover when the first cylinder moves upward. The small cap is close to the small mouth of the bottle, and during the rotation process, the small cap is axially precessed toward the thread of the bottle mouth, and when the small cap is locked, the deformation of the spring is reduced, and the positive pressure of the rotating block on the small cap is reduced, resulting in the small cap The friction between the rotating block and the rotating block is reduced, causing the rotating block and the small cover to slip, indicating that the small cover has been locked at this time. The action process of the rotary cap screwing mechanism 8 is divided into cap removal and cap screwing, wherein the cap removal process includes: (1) the fourth cylinder of the upper cap part stretches out intermittently, allowing a small cap to pass and reach the pallet; (2) The pneumatic gripper changes from the original open state to clamping, and clamps the small cover; (3) The translation cylinder moves to the right, and the small cover reaches the right cover position L2 under the drive of the pneumatic gripper; (4) The pneumatic gripper Open, the small cap falls into the rotating cylinder; (5) The translation cylinder moves to the left, driving the pneumatic gripper to reach the left cover position L1, and a cap removal action is completed at this time. The cap screwing process includes: (a) the first cylinder goes up, drives the middle frame up, the small cap in the rotating cylinder touches the bottle mouth, and then the rotating block goes down and presses the first spring, after the first cylinder is in place, the small cap is aligned and Press the bottle mouth tightly; (b) the motor starts to drive the rotating shaft, the rotating block and the small cap to rotate, and at the same time the first spring relaxes, and the rotating block and the small cap go up; (c) the small cap is tightened, and the motor stops; (d) the second One cylinder goes down, driving the middle frame to return to complete a cap screwing action. The rotary cap screwing mechanism 8 can also include an upper limit cylinder 97, which is installed above the cap screw position. Before step (c), the upper limit cylinder is pressed down to discharge the residual air in the bottle to ensure that the small cap is screwed tightly. , there is no residual air in the bottle.

It should be noted that the rotary cap screwing mechanism can adjust the tightening degree of the bottle cap by adjusting the elastic parameter of the first spring or the surface friction coefficient of the rotary block.

In this embodiment, a rotary cap screwing mechanism includes: a small cap positioning device, a rotary cylinder, a rotary block and a rotary shaft installed in the rotary cylinder, a motor, an intermediate frame, a first spring, and a first cylinder; The small cap positioning device is used to send the small cap from the upper small cap mechanism to the rotating cylinder; the rotating cylinder and the motor are installed on the middle frame; the first cylinder is connected to the middle frame , used to drive the middle frame to move up and down; the rotating block has a sliding keyway and several small bosses; one end of the rotating shaft is connected to the rotating block through a sliding key, and the other end is connected to the motor by a coupling Connected, and set in the first spring. In this embodiment, the rotary cap screwing mechanism can realize automatic cap screwing action, the cap screwing is efficient and accurate, and the packaging efficiency and quality of the product are improved.

The above is a detailed introduction to a rotary cap screwing mechanism provided by the utility model.
