Technical field
The invention belongs to sewing machine technique field, particularly the special chain type sewing machine of a kind of knit cap.
Background technology
Existing a lot of Sewing machines, inside is outmoded treadle type sewing machine structure, does not all reach industrial sewing machines requirement from the fit clearance of parts heat treatment and each parts, as easy as rolling off a log damage, stuck, and machine service life is short.And noise is large, machine in use vibrates very large, and platen can irregular positioning all around.Need hand oiling, treadle type sewing machine does not have interior liquefaction pump, needs workman constantly to add lubricating oil in use procedure, thus gives machine intimate part fuel feeding, and working machines has oil and splashes out in tank filler sleeve after interpolation lubricating oil, therefore many workmans can wear blouse and to wear a hat work.Traditional Sewing machines adjustment and maintenance is inconvenient, and crochet hook and eedle will be finely tuned, and need the screw of part whole on lower main axis to unclamp, and adjusted by mobile lower shaft, this machine machine has almost been torn open by so being equivalent to.
Summary of the invention
For the problems referred to above, the object of this invention is to provide the special chain type sewing machine of a kind of knit cap.
Technical solution of the present invention: the special chain type sewing machine of a kind of knit cap, comprises belt pulley, main shaft, eccentric cam assembly, turbine, oil pump, spindle synchronous belt wheel, Timing Belt, thread take-up tension lever crank, thread take-up tension lever assembly, crochet hook; Described spindle synchronous belt wheel is fixed on main shaft by key; Described main shaft comprises main shaft and lower main axis; Described spindle synchronous belt wheel comprises spindle synchronous belt wheel and lower main axis synchronous pulley; Described eccentric cam assembly comprises feeding eccentric cam assembly and lifts tooth eccentric cam assembly; Described belt pulley is bolted on the right of lower main axis; Described feeding eccentric cam assembly is bolted on the centre position of lower main axis; Describedly lift the left side that tooth eccentric cam assembly is bolted on lower main axis; Described turbine is fixed on the lower main axis on the lower main axis synchronous pulley left side by key; Described oil pump is connected with turbine by gear; Described Timing Belt two ends are arranged on upper and lower spindle synchronous belt wheel respectively, and stretchingly tighten; Described thread take-up tension lever crank is arranged on the left side of upper main shaft by bolt; Described thread take-up tension lever assembly is arranged on the crank of thread take-up tension lever crank; Described crochet hook is arranged on lower main axis left end by copper sheathing and holding screw.
Further, the feeding rod in described eccentric cam assembly and feeding rod wobble crank adopt ductile cast iron material.
Further, the shank in described thread take-up tension lever assembly adopts the tempering of 40Cr carburizing and quenching.
Further, described upper and lower main shaft adopts spindle synchronous belt wheel transmission, and the gearratio of upper and lower spindle synchronous belt wheel is 1: 1.
Further, described crochet hook 360 degree of rotation hook lines.
Beneficial effect:
Compared with prior art, the special chain type sewing machine of knit cap of the present invention.Support installs additional interior liquefaction pump, and drive oil pump gear to make operation of oil pump by rotating lower main axis and worm gear, oil pump can give head and support two position part fuel feeding, simultaneously also can the lubricating oil that precipitates of circulation and stress head, the comprehensive oil sealing process of casing.Upper lower main axis adopts single-groove grooved ball bearing framework, to compare original steel bushing frame mechanism, reduce the wearing and tearing of main shaft to greatest extent, alleviate machine startup load simultaneously and coefficient of friction is dropped to minimum, ensure that machine is under 3500 revs/min at the uniform velocity situation, set noise is lower than 75 decibels.The present invention adopts shank take-up, bearded needle to hook line, and composition single thread chain stitch, neat, firm, the attractive in appearance and high resilience of stitching, can expand along with woven product or shrink.
