Description

Technical Field

[0001] The utility model specifically relates to an automatic cutting mechanism for welding wire winding, belonging to the technical field of welding wire processing. Background Art

[0002] Welding wire is a metal wire welding material used as filler metal or as a conductive electrode. The welding wire is both a filler metal and a conductive electrode. Its surface is not coated with anti-oxidation flux. It is widely used in industrial production. After the welding wire reel is completed, it needs to be cut off using an automatic cutting mechanism to facilitate subsequent transportation and use.

[0003] As disclosed in the publication number: CN219786418U, a welding wire winding and cutting mechanism comprises an auxiliary box, a cutting assembly is arranged on one side of the auxiliary box, and the cutting assembly comprises a micro hydraulic cylinder, a knife holder and a pad, the micro hydraulic cylinder is fixedly connected to the top of the auxiliary frame, the auxiliary frame is fixedly connected to the connecting strip, one end of the connecting strip is fixedly connected to the side wall of the pad, and the other end passes through the fixed box and the side wall of the auxiliary box respectively. In the utility model, the position of the blade can be movably adjusted to change the spacing between the end of the welding wire and the winding reel to avoid excessively long welding wire residue after cutting, and two micro hydraulic cylinders are used to drive the knife holder to move downward to avoid the trouble of manually pressing the knife handle, and the operation is relatively quick, the limit rod can assist the connection and separation of the positioning disk and the adjusting disk, the telescopic rod and the spring are guided for the movement and resetting of the adjusting disk, which is convenient for the rapid disassembly of the winding reel and the removal of the wound welding wire, saving time and effort.

[0004] The common automatic cutting mechanism for welding wire winding can cut the welding wire through the cutting blade when in use, and can also move and adjust the position of the cutting blade to change the distance between the end of the welding wire and the winding reel to avoid the welding wire remaining too long after cutting. However, when cutting the welding wire, the cutting blade and the pad are rigidly collided, lacking a buffer structure, which can easily damage the cutting blade and reduce its service life. Moreover, the welding wire may be in a bent state before cutting, thus affecting the cutting effect. Utility Model Content

[0005] The utility model aims to solve the deficiencies of the prior art and provide an automatic cutting mechanism for welding wire winding, so as to prevent the cutting blade from being damaged and straighten the welding wire during the cutting process.

A threaded rod is threadedly connected to one side of the circular disc, and the threaded rod is rotatably connected to the annular plate.
