Description

Technical Field

[0001] The present invention relates to the technical field of medicine bottle (bottle) packaging equipment, in particular to an automatic capping machine. The automatic capping machine is used to perform capping operations on filled medicine bottles, and the medicine bottles are especially glass bottles. Background Art

[0002] Bottled medicines are widely used in the medical field, such as injection drugs, oral liquid drugs, etc. Glass medicine bottles (referred to as medicine bottles) are usually used in the production of bottled medicines. After the medicine bottles are filled, they need to be capped and sealed. During the capping and sealing, the bottle caps (such as aluminum caps, aluminum-plastic caps, etc.) need to exert a certain downward pressure to seal them in place, and then the capping operation of the bottle caps is completed through the side capping mechanism to ensure the sealing of the medicine bottles and the shelf life of the medicines.

[0003] Some existing capping machines use manual capping (mostly small capping machines). Each time, you can only manually place a medicine bottle in place, manually apply downward pressure to the capping head to complete the downward pressure of the bottle cap, and then manually apply force to the capping knife to rotate along the bottle cap for at least one circle to complete the bottle capping operation, and then remove the capped medicine bottle and repeat the above operation for the next medicine bottle. The operation is cumbersome, slow, and inefficient. The accuracy of placing the medicine bottle in place is not enough, and the operator needs to have a certain degree of proficiency. The operator's labor is large, which increases the production cost and the yield rate is difficult to control.

[0004] Some existing capping machines use semi-automatic capping. The medicine bottles are placed manually, and the capping head automatically presses down or lifts up to complete the pressing of the bottle caps. The capping knife automatically rotates along the bottle caps for multiple circles to complete the capping operation. The operation speed has been improved, and the positioning of the medicine bottles is more accurate, but it can usually only adapt to 1 to 3 specifications of medicine bottles. The versatility is low, and most of them have complex structures. Two or more capping knives are required. During the capping operation, the medicine bottles are fixed and the capping knife needs to rotate along the bottle caps for multiple circles, which is not easy to maintain. Multiple capping knives also make the equipment debugging more cumbersome.

[0005] Some of the existing capping machines use fully automatic capping to transfer medicine bottles through the assembly line. The capping machine needs to be equipped with a transmission mechanism for conveying medicine bottles. The operation speed is fast and the positioning of medicine bottles is relatively accurate, but it occupies a large area and is difficult to move, transport and install. In addition, most of them have complex structures and need to be equipped with two or more capping knives. During the capping operation, the medicine bottle is fixed and the capping knife needs to rotate along the bottle cap for multiple circles. It is not easy to maintain and service, and the equipment debugging is cumbersome and requires professional debugging and maintenance.

[0089] After the capping is completed, the pressing control mechanism drives the capping mechanism away from the capping mechanism, and the lifting control mechanism drives the pressing control mechanism to rise, and the medicine bottle is removed from the bottle placing mold table 4.

[0090] Through the above operation, the automatic capping machine is simplified, the rotation of the medicine bottle replaces the rotation of the capping mechanism, only a single capping knife is needed to cap the bottle cap, and the capping machine is small and easy to move and carry.
