The constant tension yarn guide device comprises a base (1), a rocker (3), yarn guide pulleys (11, 14 and 31), a compression spring (4) and magnetic steel (5). The rocker (3) and the base (1) are movably connected through a hinge (2), the yarn guide pulleys (11, 14 and 31) are located on the same vertical plane, the compression spring (4) is located between the base (1) and the rocker (3), and the compression spring (4) is fixedly connected with the base (1) and the rocker (3). The magnetic steel (5) is installed at the right ends of the base (1) and the rocker (3), and the two ends of the base (1) are respectively provided with a yarn guide ring (13). According to the constant tension yarn guide device, the tension of yarn is regulated in a mode that the compression spring and the magnetic steel are combined, the tension on the yarn can be effectively kept constant, the spinning quality is improved, and the raw material utilization rate and the production efficiency are improved.
Description
Technical field
The utility model relates to a kind of thread-carrier, is specifically related to a kind of permanent tension finger.
Background technology
Thread-carrier is the very important building block of field of textile machinery application, elastic wire guide of employing that existing thread-carrier is general, yarn is mutually vertical with elastic wire thread-carrier, when thering is certain pulling force on yarn, yarn drives elastic wire bending, when being released on yarn, elastic wire drives yarn to recover under the effect of elastic force.But in prior art, there is a problem, the stressed bending of elastic wire when thering is larger pulling force on yarn, its elastic force increases with deflection, therefore on yarn, suffered pulling force does not only reduce to increase on the contrary, the strength inequality that causes yarn to be subject to, affect spinning quality, and easily break when yarn is subject to larger pulling force, cause the reduction of raw-material loss and efficiency.
Utility model content
The utility model is for prior art deficiency, provide a kind of simple in structure, thread-carrier easy to use, can effectively maintain the pulling force that yarn is subject to constant, improve spinning quality, improve utilization rate of raw materials and production efficiency, avoid because Quality Down, material unaccounted-for (MUF) and the loss in efficiency that yarn unbalance stress causes.
For solving the problems of the technologies described above, the utility model provides a kind of permanent tension finger, comprise base (1), rocking arm (3), guide pulley (11, 14, 31), stage clip (4) and magnet steel (5), described rocking arm (3) with base (1) for to be flexibly connected by hinge (2), described guide pulley (11, 14, 31) on a perpendicular, use respectively bearing pin (12, 15, 32) be movably connected on base (1) and rocking arm (3), described stage clip (4) is positioned between described base (1) and rocking arm (3), and be fixedly connected with rocking arm (3) with described base (1) respectively, described magnet steel (5) is installed on the right-hand member of described base (1) and rocking arm (3).
Wherein, on described guide pulley (11,14,31) cylindrical, there is a circle groove.
Wherein, described base (1) and described rocking arm (3) left end are flexibly connected by hinge (2).
Wherein, the two ends of described base (1) are respectively arranged with a yarn guiding ring (13).
Wherein, the polarity of described magnet steel (5) opposite face is contrary.
Compared with prior art, the utility model adopts the stage clip mode of being combined with magnet steel to regulate the tension force of yarn, can effectively maintain the pulling force that yarn is subject to constant, improves spinning quality, raising utilization rate of raw materials and production efficiency.
Accompanying drawing explanation
Fig. 1 is the front view of the permanent tension finger of the utility model.
Fig. 2 is the upward view of the permanent tension finger of the utility model.
Fig. 3 is the permanent tension finger rocking arm of the utility model force diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.
The structure of the permanent tension finger of the utility model as depicted in figs. 1 and 2, comprise base 1, rocking arm 3, guide pulley 11,14,31, stage clip 4 and magnet steel 5, described rocking arm 3 with base 1 for to be flexibly connected by hinge 2, described guide pulley 11,14,31 on a perpendicular, uses respectively bearing pin 12,15,32 are movably connected on base 1 and rocking arm 3, described stage clip 4, between described base 1 and rocking arm 3, and is fixedly connected with rocking arm 3 with described base 1 respectively, and described magnet steel 5 is installed on the right-hand member of described base 1 and rocking arm 3.
In the present embodiment, on guide pulley 11,14,31 cylindricals, have a circle groove, yarn embeds in this groove, can effectively prevent that yarn from jumping out guide pulley in motion process.
In the present embodiment, base 1 and rocking arm 3 left ends are flexibly connected by hinge 2.
In the present embodiment, the two ends of base 1 are respectively arranged with a yarn guiding ring 13, its role is to guide yarn and the mating reaction of yarn pulley to make yarn in running, be difficult for escape guide wheel.
Be illustrated in figure 3 permanent tension finger rocking arm force diagram.During use, the pulling force that is subject to when yarn is less, and (be less than maximum elastic force that 3, rocking arm can provide f) time, rocking arm 3 moves in bc section, for yarn provides extra elastic force, makes yarn in motion process, maintain required elastic force.When being subject to larger pulling force on yarn, (be greater than maximum elastic force that 3, rocking arm can provide f) time, rocking arm 3 moves in ab section.In ab section; the elastic force that rocking arm 3 is subject to constantly reduces to a from b; therefore can reduce the suffered pulling force of yarn; its limiting condition is: when rocking arm 3 is when rocking arm 3 and base 1 are almost parallel during at a state; the elastic force minimum being now subject on rocking arm 3 produces extra elastic force to yarn hardly; therefore can realize when yarn is subject to larger pulling force guider and reduce self elastic force and reduce the pulling force that yarn is subject to, guarantee that the excessive and short-term of pulling force that yarn is unlikely to be subject to and the pulling force maintaining on yarn fluctuate in less scope.
These are only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
