As preferably, described upper compression strip assembly and lower compression strip assembly are same structure, described upper compression strip assembly comprises compression strip, described compression strip is provided with equally distributed pressure-ray film, be plugged with line pressing bolt in the described compression strip, between described line pressing bolt and pressure-ray film by the crimping of line ball spring phase.
As preferably, the rear of described wire clamp frame is provided with the back cover that fixes with it, and the bottom of described back cover is provided with support, and the lateral wall of described support is provided with outward extending supporting plate.
Operation principle: embroidery machine is that floss silk is sewn on the cloth, forms stitching, assembles embroidered pattern by stitching.Floss silk has two kinds, and a kind of is upper thread, and it mainly is above cloth, plays main decoration function.Another kind is bottom line, and it mainly is below cloth, helps out, and the embroidery stitching is interweaved in cloth by upper thread and bottom line and consists of.Embroidery machine is in work, and eedle passes cloth with upper thread, behind the arrival lower dead point position, upwards promotes.Because there are friction between the two in cloth and upper thread, so upper thread do not have Synchronous lifting, and need the wire jumper bar to promote upper thread tightened up on cloth.Upper thread need to have certain tension force in seam embroidery process, just can make stitching reach the requirement of embroidery.Generally speaking, the stitching of embroidery then requires: smooth, wrinkle resistant, flotation line not.Because the requirement of stitching is arranged, then the line tension of upper thread is then required highlyer, floss silk requires highly stable tension force, and stability bandwidth is below 2%, and the linear rate of adjustable tension is more than 97%.
Upper thread from the coil of wire out, through several coils of crossing, from top to down, entering surface line clamping device top, again from clamp clamp device bottom out after, just have certain tension force, enter shank and thread ram means, can carry out the thorn cloth embroidery.
During upper thread entering surface wire clamp, at first enter the compression strip assembly, two contact-making surfaces of the compression strip in the upper compression strip assembly and pressure-ray film are combined, these two contact-making surfaces are to polish through Precision Machining, its surface is very smooth, line ball spring one end is close to line pressing bolt, other end pushing pressure-ray film, make pressure-ray film to the certain pressure of the parallel generation of compression strip, when the embroidery upper thread between compression strip and the pressure-ray film by the time, the pressure of pressure-ray film produces certain frictional force to upper thread, make upper thread in the decline process, produce tension force, pressure-ray film has smooth fillet in import and the outlet of floss silk, makes floss silk when high-speed cruising, is not subjected to the interference of any bad damping.
In like manner descend the compression strip assembly also to make upper thread produce certain tension force, owing to the rectangular symmetrical that is shaped as of compression strip and pressure-ray film, therefore, the line tension of generation is very stable.
Upper thread gets off from upper compression strip assembly, through nut assembly, in the nut assembly by 2 tension discs, the tension disc shape resembles like disc-shaped, face between the tension disc contacts, and the flatness on its plane and roughness all are very high brightness, in a side of tension disc a line ball spring is arranged, one end of line ball spring contacts with tension disc, and the line ball spring produces pressure to tension disc.In like manner when upper thread by between 2 tension discs during the plane because tension disc is subjected under the effect of line ball spring, upper thread is produced pressure, upper thread owing to there is pressure to produce friction, makes upper thread produce tension force when down sliding.
Because the tension disc surface is very smooth, therefore the upper thread process is that tension force is highly stable, the line ball knob can be with manually being rotated, after the rotation, axial generation displacement at the line ball column cap, thereby changed the distance of two end faces of line ball spring, the line ball spring has also been changed the pressure that tension disc produces, thereby changed the tension force of upper thread.
Upper thread from nut assembly out passes through the wire-crossing wheel assembly again, and upper thread is above wire-crossing wheel, and during the alignment lower slider, wire-crossing wheel will produce the phenomenon of rolling face to face, and wire-crossing wheel and wire-crossing wheel sheet all are to be contained on the roller bearing, and the three can form together and rotatablely move.When wire-crossing wheel rolled, the wire-crossing wheel sheet also produced synchronously and rolls.At the wire-crossing wheel sheet inductor is housed, when upper thread is gliding, because linear pressure is unstable, makes and on the wire-crossing wheel sheet inductor is housed and senses information, thereby regulate embroidery speed, play the purpose of stability line tension force.
Each assembly plays the effect of certain generation tension force, and can regulate line tension, can regulate the speed of corresponding with it embroidery.
Therefore, a kind of novel embroidery machine top thread clamp device that the utility model provides, compact conformation possesses regulating action, Improving The Quality of Products.
