Problems solved by technology

[0002] Many existing sewing machines have an old pedal-operated sewing machine structure inside. The heat treatment of parts and the fit clearance of each part cannot meet the requirements of industrial sewing machines. They are easily damaged and stuck, and the service life of the machine is short.
Moreover, the noise is large, the machine vibrates greatly during use, and the table will move irregularly back and forth, left and right
Manual oiling is required. Pedal sewing machines do not have an internal oil pump. Workers need to continuously add lubricating oil during use to supply oil to the internal parts of the machine. After adding lubricating oil, oil will splash out from the oiling hole when the machine is running, so many Workers will wear smocks and hats to work
Traditional sewing machines are inconvenient to adjust and maintain. If you want to fine-tune the crochet and needles, you need to loosen all the screws on the lower spindle and adjust by moving the lower spindle. This is equivalent to dismantling the machine.

Abstract

The invention relates to a chain type sewing machine special for a knitted hat. The chain type sewing machine special for the knitted hat comprises a belt wheel, a spindle, an eccentric cam assembly, a turbine, an oil pump, a spindle synchronous belt wheel, a synchronous belt, a take-up-lever crank, a take-up-lever assembly and a crochet hook. The spindle synchronous belt wheel is fixed to the spindle through a key. The spindle comprises an upper spindle body and a lower spindle body. The spindle synchronous belt wheel comprises an upper spindle synchronous belt wheel body and a lower spindle synchronous belt wheel body. The eccentric cam assembly comprises a feeding eccentric cam assembly and a tooth lifting eccentric cam assembly. Single thread chain type stitches are formed through needle bar take-up and crotchet needle thread hooking, and the stitches are tidy, firm, attractive, rich in elasticity, and capable of expanding or shrinking along with knitted products.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a special chain sewing machine for knitted hats. Background technique [0002] Many existing sewing machines have an old pedal-operated sewing machine structure inside. The heat treatment of parts and the fit clearance of each part cannot meet the requirements of industrial sewing machines. They are easily damaged and stuck, and the service life of the machine is short. Moreover, the noise is high, the machine vibrates greatly during use, and the platen will move irregularly back and forth, left and right. Manual oiling is required. Pedal sewing machines do not have an internal oil pump. Workers need to continuously add lubricating oil during use to supply oil to the internal parts of the machine. After adding lubricating oil, oil will splash out from the oiling hole when the machine is running, so many Workers will work in smocks and hats. Traditional sewing machines a...
