Weaving loom with magnetic shuttle

摘要

Weaving loom has driving wheel (501) and driven wheel (512) which are provided on machine frame (50) and each wheel has rim with annular groove (517). Magnet unit (514) is provided in inner surface (is) of driving belt and shuttle (152) moves with in grooves of wheel (501) is also provided in is of belt. The shuttle is attracted towards magnet unit during its movement with in driving and driven wheels. The weaving loom has warp supplying mechanism (3) for feeding warps (31) and the shedding mechanism (4) for forming shed between warps (31). The weft picking mechanism (5) is provided for picking weft into shed and weft beating mechanism (6) for beating weft into fell in shed. The machine frame has fixed upper race rail (502) with top surface. The bottom surface of upper race rail and top surface of lower race rail are formed with open-ended longitudinal guide slot (503) and provided with fixed longitudinal plates which extends respectively into side portions of guide slot to locate shuttle (52) between upper and lower race rails (501,502). The longitudinal plates connects shuttle within the guide slot (503). The longitudinal guide slots have shuttle inlet (503') through which shuttle moves into longitudinal guide slot (503) and shuttle outlet from which shuttle leaves longitudinal guide slot. The pressing roller units (505, 95) are located respectively near the shuttle inlets of longitudinal guide slots. The pressing roller units have a row of pressing rollers (505, 951) which abut against the outer surface of the driving belt. The beating mechanism (6) has reed assembly (60) having rows of reed dents (61) and swinging device (62) which is connected to reed dents for swinging reed assembly (60). The reed dents have horizontal portion so as to form a flat shuttle guide way (601) on top surfaces of horizontal portions of reed dents. The elongated wedge shaped divider (53) provided in the machine frame is fixed near the driving wheel (511). The wedge shaped end (532) is away from shuttle guide way (601) so that shuttle (52) moves from driving wheel (511) along driving belt (513) to wedge shaped end (532) of the divider. The machine frame has shuttle depressing unit (54) which is located over divider (53). The driving wheel (511) is provided with a fixed rotating shaft (518) about which driving wheel rotates. The magnet unit has magnet (516) and elongated and corrugated longitudinal plate (516) which is fixed on driving belt (513) so as to provide magnets receiving spaces (516') between corrugated plate (516) and driving belt (513). The inner surface of the driving belt is formed with longitudinal rows of teeth (515) between which corrugated longitudinal plate (516) is fixed.
