Abstract
The thread taking-up crank arm mechanism for thick material sewing machine is one four or five crank arm mechanism. The thread taking-up crank arm mechanism has increased length of the second thread taking-up rod and decreased length of the third thread taking-up rod, so that it has obviously fast thread taking-up speed, obviously decreased needle-thread tension and raised comprehensive performance. The thread taking-up crank arm mechanism for thick material sewing machine of the present invention may be matched with various thread hooking mechanisms to constitute various types of thick material sewing machine.
Description
The present invention relates to make the thread take-up mechanism of 300 class chain stitch sewing machines.
The mechanism of making 300 class chain stitch sewing machines at present in the world is mainly by thorn material lead wires mechanism, string-hooking mechanism, four great institutions such as thread take-up mechanism and feed mechanism composition.Sewing machines will be finished the process of a stitching, the eedle of main spinosity material lead wires mechanism, and the shuttle of string-hooking mechanism (rotating shuttle or shuttle), four critical parts such as the feeding tooth of the thread take-up tension lever of thread take-up mechanism and feed mechanism are finished in certain sequence.The effect of the thread take-up tension lever of thread take-up mechanism (hole) is supply and reclaim an amount of needlework in the stitching forming process, and the knot that needlework and shuttle thread are formed is taken out tight in the middle of sewing and replenished the needlework that each stitching is consumed.The thread take-up mechanism of Sewing machines has the cam thread take-up mechanism, connecting rod thread take-up mechanism (the connecting rod thread take-up mechanism has four connecting rods and five connecting rod thread take-up mechanisms) ... Deng.The connecting rod thread take-up mechanism: four connecting rod thread take-up mechanisms (four connecting rod thread take-up mechanisms be called for short four lever take-up mechanism, formal name used at school crank and rocker mechanism) are made up of four member hinges such as thread take-up crank (crank) thread take-up tension lever (connecting rod and working beam) line-choosing connecting rod (rocking bar) casing (frame) and main shaft.Five connecting rod thread take-up mechanisms (being called for short five lever take-up mechanisms) are to increase a wobble crank member hinge to form on the basis of four connecting rod thread take-up mechanisms, wobble crank is by the wobble crank control system that is installed on the same main shaft---and crank and rocker mechanism is handled, (crank and rocker mechanism is mainly by eccentric wheel, connecting rod, four members such as rocking bar and casing are formed.) make wobble crank make reciprocally swinging.(regulate the position of the eccentric wheel orientation angle of crank and rocker mechanism, the stroke size of the thread take-up tension lever of thread take-up mechanism is changed, become five lever take-up mechanisms that to regulate for the line amount.) because that Sewing machines uses is wide, so kind is a lot of, industrial sewing machines, the particularly Sewing machines that super-thick material uses of sewing also have many kinds, have desktop type, the cartridge type type, flat type; On the pattern of thread take-up mechanism, divide cam thread take-up mechanism and connecting rod thread take-up mechanism.The most of kinds of its thread take-up mechanism of Sewing machines that the super-thick material of sewing at present, is both at home and abroad used adopt the cam thread take-up mechanism, also have the part kind to adopt the connecting rod thread take-up mechanism.The thread take-up tension lever of cam thread take-up mechanism (hole) take-up peak position in thread take-up tension lever (hole) the take-up peak position of 60 ° of (is 0 ° with the eedle peak) connecting rod thread take-up mechanisms at 69 °～70 °.The two is compared, the thread take-up tension lever of cam thread take-up mechanism (hole) is than fast 9 °～10 ° of the peak position of thread take-up tension lever (hole) take-up of connecting rod thread take-up mechanism, be fast 9 °～10 ° of take-up time, its effect is that the needlework tension force of its needlework tension force of the fast Sewing machines of the take-up Sewing machines slower than take-up is little.(the needlework tension force of Sewing machines is good with " little ".) the sewing principle and the rule of Sewing machines be: sewing thickness is thick more and long more its needlework tension force of distance between needle point tracers is just big more.It is to make the super-thick material article specially for the super-thick material Sewing machines, as various super-thick material tents, canvas, cushion uniform thickness heavy burder.The needlework tension force of super-thick material Sewing machines is all obviously very big both at home and abroad at present.
The connecting rod thread take-up mechanism that the purpose of this invention is to provide a kind of super-thick material use in sewing machine, thread take-up tension lever (hole) the take-up peak position that it can make the connecting rod thread take-up mechanism has significantly " soon " than the peak position of thread take-up tension lever (hole) take-up of the connecting rod thread take-up mechanism of prior art, can be approaching, reach, surpass thread take-up tension lever (hole) the peak position of cam thread take-up mechanism, to reduce the tension force of needlework.
The object of the present invention is achieved like this: the technical program be on the basis of connecting rod thread take-up mechanism (the connecting rod thread take-up mechanism comprises four connecting rod thread take-up mechanisms and five connecting rod thread take-up mechanisms) in prior art four connecting rod thread take-up mechanisms---the length l of thread take-up crank (1) OA
