Description

Technical Field

[0001] The utility model relates to the technical field of dental floss production, specifically a wire breaking device for the production of dental floss rods. Background Technique

[0002] During the production process of dental floss rods, wire breaking is required mainly because the two ends of the dental floss rods are usually designed with specific shapes for the convenience of users to wind dental floss. These specific shapes need to be cut and manufactured after the dental floss rods are formed to ensure that the two ends of the dental floss rods meet the design requirements.

[0003] A wire breaking device for a dental floss rod processing device disclosed in the existing patent publication number CN216803579U includes a mounting plate and a hydraulic cylinder. When in use, the connected dental floss rods are placed on the workbench, and the dental floss rods at both ends are respectively abutted against the mutually approaching sides of two positioning plates. Then, the electric push rod is started to drive the pressing plate to fix the two dental floss rods at both ends. Finally, the hydraulic cylinder is started to drive the tool mounting plate to move downward so that the wire breaking knife is adapted to the cutting groove.

[0004] When the above device performs wire breaking treatment on dental floss rods, the dental floss rods at both the head and tail sides are fixed. During the downward pressing process of the blade, some dental floss may not be completely broken, which will cause displacement of some dental floss rods. When cutting again, it is necessary to align the position where the blade presses down to place the dental floss rods, which is rather troublesome. In view of the above problems, a wire breaking device for the production of dental floss rods is proposed. Content of the Utility Model
