Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap positioning ring cutting equipment, in particular to a positioning ring cutting machine. Background Art

[0002] As people's awareness of resource conservation and environmental protection gradually increases, it will be a general trend to use environmentally friendly bottle caps for beverage bottles in future life. The difference between environmentally friendly bottle caps and ordinary bottle caps is that the cover body of the ordinary bottle cap is separated from the bottle body after opening, while the cover body of the environmentally friendly bottle cap is not completely separated from the bottle body after opening, and there is still a partial connection between the two. In life, ordinary bottle caps are easily lost and become garbage after being separated from the bottle body after opening, which is not convenient for recycling. Environmentally friendly bottle caps do not have this problem, thereby achieving the purpose of environmental protection. In addition, in the existing bottle caps, a pair of pointed ends are partially provided inside for piercing the sealing film. During the ring cutting process, the hinge between the bottle cap and the fixed seat needs to be kept away from the pair of pointed ends. Otherwise, if the distance between the tip and the hinge is too close, it is easy to cause the tip to interfere with the lower end when the bottle cap is closed for the second time. The above two situations both involve the problem of fixed-point positioning of the bottle cap ring cutting.

[0003] In the prior art, there are knives for continuous ring cutting. For example, the patent document with the publication (announcement) number CN112591300B discloses an environmentally friendly bottle cap ring cutting tool, including a cutting tool assembly and a cutting tool assembly fixing seat. The cutting tool assembly is fixedly mounted on the cutting tool assembly fixing seat. The cutting tool assembly includes a circumferential cutting tool and at least two longitudinal cutting tools arranged at an angle with the circumferential cutting tool. Each longitudinal cutting tool is arranged at intervals in the circumferential direction. The circumferential cutting tool is used to cut a circumferential cutting seam extending along the circumference of the anti-theft ring on the anti-theft ring of the bottle cap. The length of the blade of the circumferential cutting tool is less than the circumference of the anti-theft ring to be cut, thereby cutting a circumferential cutting seam with a disconnected portion. The longitudinal cutting tool is used to cut a longitudinal cutting seam perpendicular to the circumferential cutting seam at the disconnected portion of the circumferential cutting seam. When the environmentally friendly bottle cap ring cutting tool of the present application is used, it can directly replace the ring cutting tool in the existing bottle cap ring cutting machine, thereby processing an environmentally friendly bottle cap; when it is necessary to make environmentally friendly bottle caps of different specifications, it can be achieved by replacing parts such as the ring cutting tool and the cutting head. However, it only solves the problem of continuous ring cutting of the bottle cap, but it is difficult to solve the problem of fixed-point positioning cutting of the bottle cap during the ring cutting process.
