Description
Technical field
The invention belongs to the sewing machine technique field, what relate to a kind of multi-needle machine draws materials device and presser foot lifting device.
Background technology
When Sewing machines is worked, when the upper and lower pricker of eedle and hook line, cloth will ceaselessly move forward.The pay-off of existing Sewing machines is to utilize the feeding of feed dog gear mechanism, not only can cause feeding, presser foot lifting device and tooth processed complex when as more as eedle, pin hole on the pin felt easily is out of shape, cause the raising of production cost and the decline of quality, cause sewing up stitching inhomogeneous and unstable, affect suture quality.For this reason, people have designed various materials device and the presser foot lifting devices of drawing and have been used for cloth-traction.
The cloth for sewing machine sheet haulage gear [patent No.: CN201020630273.1 provided as State Intellectual Property Office of the People's Republic of China, notification number: CN201952615U], the Sewing machines that comprises workbench and be arranged on workbench is sewed up syringe needle, it is characterized in that: be provided with the cylinder (A) that is positioned at the board bottom side on described workbench and be positioned at the cylinder (B) of board top, two cylinders cooperatively interact in order to affecting cloth, this cloth for sewing machine sheet haulage gear can replace left hand to sewing up the traction booster action of cloth, simple in structure, easy to operate, improve formation efficiency, there is great use value.Multi-needle machine is when work, and the motion of cloth is advance or stop according to the motion of presser foot lifter, and this double-roll traction machine structure can not coordinate presser foot lifting device well.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, what proposed a kind of and the much higher pin machine of fitness draws materials device and presser foot lifting device.
Purpose of the present invention can realize by following technical proposal: a kind of multi-needle machine draw materials device and presser foot lifting device, it is characterized in that, the drawing materials device and presser foot lifting device to comprise presser foot lifting device and be arranged on the materials device that draws after presser foot lifting device of this multi-needle machine, the described materials device that draws comprises the eccentric wheel by main shaft drives, link assembly one, be arranged on upper roller and lower roller on frame, being provided with gap between described upper roller and lower roller can be for the cloth turnover, eccentric wheel drives lower roller by link assembly one and rotates, described lower roller is provided with the one-way clutch that does not drive the lower roller reversing when link assembly one back swings, also be provided with on described frame and can promote the cylinder one that upper roller is done elevating movement, described presser foot lifting device comprises the transmission mechanism be connected with described eccentric wheel, can be along frame the pressure foot assembly do the oscilaltion campaign, described transmission mechanism can make the pressure foot assembly rise along frame under eccentric wheel drives, also be provided with the spring that makes the pressure foot assembly there is the trend of moving down on described frame.
Main shaft drives rotation by motor, and main shaft rotarily drives eccentric wheel and rotates, and eccentric wheel rotates and drives lower roller by link assembly one and rotate, and lower roller and the upper roller extruding cloth that matches, pull cloth forward.But when back swinging, link assembly one will drive the lower roller reversing, cause like this cloth to be regained again backward, thus one-way clutch is set on lower roller, when link assembly one is back swung and lower roller disconnect power and transmit, lower roller stops operating so, and cloth just can be by past loopback yet.On main shaft, another group eccentric wheel drives the transmission mechanism operation, and the pressure foot assembly is subject to transmission mechanism and does elevating movement, leaves cloth or compresses cloth.By adjusting coordinating of main shaft and eccentric wheel and link assembly one, can make lower roller make the one-directional rotation at intermittence, pull cloth, thereby reach with the action of pressure foot assembly, synchronize.The pressure foot assembly rises, and one-way clutch makes link assembly one and lower roller disconnect the power transmission, draws materials device to stop drag cloth; Pressure foot descends and cloth is flattened, and lower roller starts to rotate, and draws materials device work and pulls cloth to advance.
Draw materials device and presser foot lifting device at above-mentioned multi-needle machine, described link assembly one comprises being enclosed within on eccentric wheel by eccentric wheel and drives the connecting rod one swung, the connecting rod two hinged with connecting rod one, one-way clutch is contained on connecting rod two, and described one-way clutch is fixed on the lower roller axle.Eccentric wheel rotates drivening rod one and swings, and connecting rod two makes the lower roller one-directional rotation by one-way clutch.
Above-mentioned multi-needle machine draw materials device and presser foot lifting device, described one-way clutch is that inner ring is fixed on the unidirectional needle bearing on the lower roller axle, described connecting rod two is enclosed within on the outer ring of unidirectional needle bearing.Connecting rod two swings around unidirectional needle bearing, the inner ring of unidirectional needle bearing and outer ring locking while swinging forward, and the lower roller axle and then swings; When connecting rod two back swings, the inner ring of unidirectional needle bearing and outer ring are free to rotate, and two, connecting rod drives outer ring rotating, and lower roller axle and inner ring stop operating.
Above-mentioned multi-needle machine draw materials device and presser foot lifting device, an end of described connecting rod one has ball head structure, on connecting rod two, has bar hole, ball head structure is fixed on the precalculated position of bar hole by nut.Unclamp nut, can make ball head structure slide in bar hole, by adjusting ball head structure in the position of bar hole, can regulate the rotation amplitude of lower roller.
Above-mentioned multi-needle machine draw materials device and presser foot lifting device, respectively be provided with the gear of a same size on described upper roller and lower roller, two gears can intermesh together.The identical gear drive by gearratio, upper roller is synchronizeed and is rotated with lower roller, pulls cloth more steady.
