Problems solved by technology
At present, this style of arm-type seam stitching special sewing machine is manually lubricated. If the operator is negligent and fails to refuel in time, it will easily lead to excessive wear or jamming of machine parts and high temperature and heat.
Since the manual refueling cannot effectively guarantee the continuous, uniform, stable and effective oil supply during the operation of the machine, it limits the overall operating speed of the machine and reduces the efficiency of the machine operation.
With manual refueling, the oil cannot be circulated and can only be refilled in one direction. There is a volatilization loss, and the impurities and stains generated during the wear and tear of the machine's running parts are always inside the machine and cannot be discharged, which further aggravates the machine. Wear and tear, affecting the service life of the machine

The invention belongs to the technical field of oil supply systems for special sewing machines, in particular to an automatic circulating oil supply system for special sewing machines. The main constant pressure overflow oil circuit and the oil supply system, the oil supply system includes an oil pump assembly, and the oil pump assembly is arranged in the oil pan in the sewing machine casing, and the four oil paths all supply oil collectively through the oil pump assembly in the oil pan, Due to the different oil supply pressure and oil volume required by each part, a relief valve is provided on each oil supply oil path to ensure the stability of the overall oil supply. The special machine body can be effectively carried out through these four oil paths. For the internal oil supply, the invention provides an automatic circulating oil supply system for a special sewing machine with simple and stable structure, fully automatic circulating oil supply and good oil supply effect.
Description
technical field [0001] The invention belongs to the technical field of oil supply systems for special sewing machines, in particular to an automatic circulating oil supply system for special sewing machines. Background technique [0002] The special sewing machine created by the present invention is an arm-type rolling seam sewing machine. The Chinese patent number of the special sewing machine, 201510697883.0 and 200820199507.4, both disclose its overall external structure and part of its internal structure. The special sewing machine is an elbow-shaped barrel type sewing machine. , used for lap sewing of men's clothing, women's clothing, casual clothing, denim clothing, shirts, overalls, raincoats, etc. At present, this style of arm-type seam seam special sewing machine adopts manual oiling and lubrication. If the operator is negligent and fails to refuel in time, it is very easy to cause excessive wear or jamming of machine parts and high temperature heating. Because the...
