Description
Technical field
The utility model relates to the pneumatic presser foot lifting device of a kind of Novel overlock machine, belongs to overlock machine technical field.
Background technology
Traditional overlock machine presser foot lifting device is all adopt electronic type of drive, and because motorized drive structure stability is more weak, fault rate is high, and maintenance rate is high, and service life is shorter, and can produce radiation after energising, and in addition, the volume of electronic presser foot lifting device is large, unsightly.For this reason, research and develop a kind of stability higher, the pneumatic presser foot lifting device of long service life becomes those skilled in the art's problem demanding prompt solution.
Utility model content
The utility model is to solve above-mentioned deficiency, provides the pneumatic presser foot lifting device of a kind of Novel overlock machine.
Above-mentioned purpose of the present utility model is realized by following technical scheme: the pneumatic presser foot lifting device of a kind of Novel overlock machine, it is characterized in that: comprise cylinder and stator, cylinder is fixed on same stator by hexagon socket head cap screw, the outer wall of described cylinder is provided with air inlet and air entry, air inlet, air entry and cylinder inner space, described air inlet, air entry connect air pressure feedway, air pressure feedway is provided with Pressure gauge, cylinder inner cavity is provided with limited block and piston, described piston connects piston rod, and piston rod is provided with link.
The utility model advantage is compared with prior art: volume of the present utility model is little, handsome in appearance, and by the action of air pressure control piston, and can control air pressure by Pressure gauge, stability is strong, failure rate is low, long service life.
