Description

TECHNICAL FIELD

[0001] The utility model relates to a beaming machine technical field especially relates to a beaming machine's bobbin frame yarn breaking device. BACKGROUND

[0002] As an important step of weaving, the purpose of beaming is to arrange a certain number of cheese yarns into a certain width according to the design requirement length, and to be wound on the beaming shaft or weaving shaft in parallel, so as to prepare for the warp yarn system of the fabric. In weaving production, the widely used beaming methods can be divided into batch beaming and strip beaming. During the beaming process, the yarn needs to be wound on the warp shaft, and after the winding is completed, the yarn needs to be cut off, and then the warp shaft wound with the yarn is disassembled from the beaming machine for subsequent process treatment.

[0003] According to the search, the patent with the publication number CN221000013U discloses a beaming machine yarn breaking mechanism, which comprises a rack and a cutting box. The inside of the rack is rotatably connected with a winding roller, and the inside of the cutting box is provided with an adjusting and replacing assembly. When the yarn is cut, the yarn is passed through the top of the bearing plate and wound by the winding roller. After winding to a certain length, the motor drives the threaded rod to rotate in the inside of the cutting box, so that the movable plate changes from rotary motion to up-down movement under the condition of the guide rod. The movable plate drives the cutting knife to move downward to cut the yarn on the top of the bearing plate, thereby reducing the strength of the cutting work. When the cutting knife is used for a period of time and the blade is rolled, the two movable blocks are pulled to drive the two clamping columns to separate from the inside of the cutting knife, so that the cutting knife can be disassembled and replaced with a new cutting knife, thereby achieving the effect of convenient tool replacement.

[0004] Although the patent can well solve the problems in the background art, the patent has the following disadvantages: in actual use, the cutting knife will have rigid contact with the bearing plate, and after a long time, the cutting edge will become blunt or the blade will be rolled. If the cutting edge is blunt, the relatively loose yarn may be laid flat in the mounting groove without being cut when the yarn is cut without being tightened. Moreover, after cutting the yarn, the cutting part needs to be bundled, and the device does not have this function. UTILITY MODEL CONTENT
