Description

Technical Field

[0001] The utility model relates to the technical field of capping devices, in particular to a plastic bottle capping device. Background Art

[0002] The capping device, usually as a part of the capping machine, is an important equipment in the packaging industry. It is mainly used to screw the bottle cap tightly onto the container to achieve the effect of sealing and preservation. It is suitable for screwing caps of different bottle shapes in the food, pharmaceutical, daily chemical, pesticide, cosmetics and other industries. In the production and processing of plastic bottles, the capping device is needed to screw the caps on the plastic bottles.

[0003] For example, the Chinese patent disclosure: A beverage bottle capping device for beverage processing, application number: CN202221662066.3, includes a capping device bottom plate, one end of the capping device bottom plate is fixedly connected to a capping device side sleeve, an arc-shaped capping card is arranged inside the capping device side sleeve, one end of the arc-shaped capping card is provided with a capping slot, one end of the arc-shaped capping card is provided with a buffer elastic member, and a rubber anti-skid pad is arranged at the top inner side of the capping device bottom plate. The beneficial effect is that in the utility model, the bottle cap is inserted into the arc-shaped capping card in the capping device side sleeve, and the buffer elastic member arranged between the capping device side sleeve and the arc-shaped capping card can play a buffer clamping effect when inserting the bottle cap, and can be adapted to a variety of bottle caps of different specifications for use, and the rubber anti-skid pad arranged at the top inner side of the capping device bottom plate can play an anti-skid effect, preventing the bottle cap from slipping when the cap is screwed.

[0004] However, in the above technical solution, when the capping device is used for capping, the arc-shaped capping clamping plate is firstly required to tightly clamp the bottle cap, and then the capping can be rotated to tighten the bottle cap. Therefore, with the long-term use of the capping device, some bottle cap fragments will inevitably adhere to the inner wall surface of the arc-shaped capping clamping plate that fits the bottle cap. These bottle cap fragments will make it difficult for the arc-shaped capping clamping plate to tightly clamp the bottle cap, resulting in the subsequent rotation and capping operation being unable to tighten due to loose clamping, thereby affecting the capping. Utility Model Content

[0005] The main purpose of the utility model is to provide a plastic bottle screw capping device, which can effectively solve the problem in the background technology that when using the screw capping device to screw caps, it is first necessary to use an arc-shaped screw capping clamping plate to tightly clamp the bottle cap, and then the screw cap can be rotated to tighten the bottle cap. Therefore, with the long-term use of the screw capping device, some bottle cap fragments will inevitably adhere to the inner wall surface of the arc-shaped screw capping clamping plate that fits the bottle cap. These bottle cap fragments will make it difficult for the arc-shaped screw capping clamping plate to tightly clamp the bottle cap, resulting in the subsequent rotation and screwing operation. The problem of being unable to tighten the bottle cap due to loose clamping, thereby affecting the screw capping.

[0008] Preferably, one end of the spring is fixedly connected to the rotating shaft.

[0009] Preferably, the sliding column comprises a sliding column base, a first umbrella wheel is rotatably arranged on the sliding column base, and a first rotating column is arranged on the first umbrella wheel.

[0010] Preferably, a second umbrella wheel is meshedly provided on one side of the first umbrella wheel, a second rotating column is provided on the second umbrella wheel, and a gear is provided on the second rotating column.

[0011] Preferably, the sliding column base is slidably arranged in a sliding groove, and the first rotating column and the second rotating column rotate and penetrate the sliding column base.

[0012] Preferably, the gear and the tooth groove are meshed with each other, and the first rotating column movably passes through the connecting block and is fixedly connected to the rotating disk.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) When the utility model is used, the bottle cap is first inserted into the elastic card plate in the side sleeve of the screw-on cap device, and then the bottle cap is inserted into the plastic bottle mouth. At this time, the plastic bottle mouth squeezes the rotating disk, causing the rotating disk to move upward, the spring is deformed, and the rotating disk continues to rotate during the movement. The rotating disk drives the flexible brush to rotate, and the flexible brush is used to clean the inner wall surface of the elastic card plate to prevent bottle cap fragments from remaining on the inner wall surface of the elastic card plate. Then, the plastic bottle is screwed on the cap. After the screwing of the cap is completed, the spring rebounds to return the rotating disk to its original position, and the flexible brush is used again to clean the inner wall surface of the elastic card plate to prevent bottle cap fragments from remaining on the inner wall surface of the elastic card plate, so as to prevent the bottle cap fragments from affecting the screwing of the cap.
