Problems solved by technology
Because the cutting action of the blade is no longer limited by the pressing force of the blade pressing spring, but is actively controlled by the cam, changing shearing into chopping, so its adaptable range is greatly expanded, and no matter what type of weft yarn can be easily cut off , compared with the old-fashioned shearing device, the number of parts is small, the mechanism is simple, and the blade is no longer made of expensive alloy materials. The use of ordinary materials can meet the requirements of use, and the cost is low. However, the shearing mechanism is equipped with an additional drive mechanism. Working, loom accessories increase, thereby increasing the cost

Embodiment Construction
[0040] In order to better understand the fabric shearing device according to the present invention, specific embodiments of the fabric shearing device according to the present invention will be described below with reference to the accompanying drawings.
[0041] refer to figure 1 , a schematic diagram of the overall structure of the fabric shearing device according to the present invention. A kind of fabric shearing device, it comprises weft yarn cutting mechanism 20 and waste edge cutting mechanism 30, and weft yarn cutting mechanism 20 and waste edge cutting mechanism 30 are driven by the motor of loom 10, does not need to be weft yarn cutting mechanism additionally like this 20 and waste edge shearing mechanism 30 are equipped with a power source, which will certainly reduce power consumption, thereby reducing the cost of production. like figure 2Shown, the structural diagram of fabric shearing device of the present invention. After the motor on the loom 10 starts, th...

The invention relates to a cloth cover and weft cutting device in the field of textile machinery, in particular to a fabric shearing device which comprises a weft yarn shearing mechanism (20) and a scrap edge shearing mechanism (30). The weft yarn shearing mechanism (20) comprises a fixing frame (21), a knife rest (22), an upper knife board (23) and a lower knife board (24), and the scrap edge shearing mechanism (30) comprises a connecting seat (31), a knife holder (35), an upper blade (32) and a lower blade (33). Cam top blocks (52) are arranged on the fixing frame (21) and the knife holder (35) respectively and abutted to cams (51), and the cams (51) are arranged on rotating shafts (50) of a weaving machine (10). When the weaving machine (10) works, a driving device of the weaving machine (10) simultaneously drives the rotating shafts (50) to rotate, so that the weft yarn shearing mechanism (20) and the scrap edge shearing mechanism (30) are driven to shear weft yarns and scrap edges, additional driving devices are omitted, and cost is saved.
Description
technical field [0001] The invention relates to a cloth surface and weft thread cutting device in the field of textile machinery, in particular to a fabric cutting device. Background technique [0002] Currently known gingham looms equipped with a weft yarn cutter can only cut ordinary glass fiber yarns, but cannot cut composite yarns normally, and the life of a weft yarn cutter is only a few hours, resulting in the gingham loom not being able to produce normally. Resulting in low production efficiency and high cost of parts replacement. In addition, if the cutting mechanism in the prior art is additionally equipped with a driving mechanism, the accessories of the loom increase, thereby increasing the cost. [0003] For example, the application number is the Chinese utility model patent of 200820024059.4, which discloses a weft waste edge shearing mechanism, including a fixed support and a shearing mechanism arranged on the fixed support. One end of the blade mounting plat...
