The auxiliary pressurizing device further comprises a pressurizing device; the pressurizing device is used for increasing the pressure of the cheese yearns and the winding roller when the diameters of the cheese yarns are increased and shortening the falling time of the cheese yarns when a cheese yarn connector falls off. According to the auxiliary pressurizing device disclosed by the invention, the pressurizing device is additionally arranged on the bobbin creel and is used for adjusting the pressure of the cheese yarns to the winding roller and shortening the falling time of the cheese yarns; the pressurizing device is simple, practical and wide in application range; the pressurizing effect of the bobbin creel can be effectively realized, the falling time can be effectively shortened, and the stability and the reliability of forming of the cheese yarns are ensured.
Description
Technical field
The invention belongs to the rotor spinning machine field, be specifically related to a kind of auxiliary pressure device of rotor spinning machine bobbin cradle.
Background technology
In the rotor spinning machine of extensive use at present, there is no pressue device on common bobbin cradle, in the process of spinning, increase along with spooler cheese diameter, weight increases thereupon, pressure between cylinder yarn and Wound-up roller also will constantly change, now, when if the pressure between cylinder yarn and Wound-up roller does not reach required pressure, in the process of broken yarn joint, the time that not only the cylinder yarn reaches constant speed can lengthen, and in the process be shaped at yarn, very easily produce pigtail yarns, reduce forming quality.
Simultaneously, a kind of Semi automatic piecing device of rotor spinning machine is disclosed in the patent of China, the patent No. is ZL200720072458.3, open day is on June 4th, 2008, concrete disclosed is that a kind of rotor spinning machine utilizes support arm to solve the electromagnet damage that electromagnet is switched on always or switched on for a long time and causes, and utilize the last item seat to solve roller and push down all the time the roller distortion of drawing the yarn axle and causing, affect the resultant yarn effect, but this semi-automatic joining for rotor spinning machine device need play a yarn with holder yarn lever bracket when joint, after joint completes, after need relying on self gravitation to fall, the cylinder yarn starts spinning, the whereabouts of bobbin cradle needs certain hour, simultaneously, in the spinning process, because spooler cheese diameter increases, the time that cylinder yarn after falling is issued to constant speed in the Wound-up roller drive also can lengthen, finally cause the yarn sample to become deformation.
Summary of the invention
The object of the invention is to, for above-mentioned deficiency, provide a kind of and can overcome the bobbin cradle pressure transient and cause the yarn forming quality to reduce in spinning process, also can shorten the auxiliary pressure device of the rotor spinning machine bobbin cradle of a yarn fall time simultaneously.
In order to reach the object of the invention, the technical scheme of taking is: a kind of auxiliary pressure device of rotor spinning machine bobbin cradle, comprise bobbin cradle, cylinder yarn, Wound-up roller and rotating shaft, a yarn is installed on the bobbin cradle that can rotate around the shaft, this yarn contacts with described Wound-up roller, also includes pressue device, and this pressue device is for when spooler cheese diameter increases, when the pressure of increase cylinder yarn and Wound-up roller and a cylinder yarn joint fall, dwindle the time that a yarn falls.
Further, described pressue device can be a kind of in stage clip or pneumatic fitting.
Preferably, described pressue device is stage clip, and an end of this stage clip is fixed on the top board fixing with the rotor spinning main beam,, the other end is free end.
In spinning process, along with spooler cheese diameter increases, weight increases thereupon, and the cylinder yarn also in continuous change, is regulated pressure by the stage clip under top board to the pressure of Wound-up roller, while making a yarn larger, to rolling up rich roller pressure, increases, and its forming quality is improved.
In the joint process, the moving bobbin cradle of cylinder cotton yarn tape falls, and except self gravitation, is attached with the pressure of stage clip, can make it fall fast, guarantees forming quality.
The present invention compared with prior art has following beneficial effect: the present invention by increasing pressue device on bobbin cradle, be used for adjusting the cylinder yarn to the pressure of Wound-up roller and shorten cylinder yarn fall time, this pressue device is simple and practical, applied range, can effectively reach the effect of bobbin cradle pressurization and dwindle fall time, guaranteeing that a yarn is shaped reliable and stable.
The accompanying drawing explanation
Fig. 1 is the structural representation of auxiliary pressure device when rotor spinning machine does not need to lift a tin yarn of rotor spinning machine bobbin cradle of the present invention.
Fig. 2 is the structural representation of auxiliary pressure device when rotor spinning machine need to lift a tin yarn of rotor spinning machine bobbin cradle of the present invention.
In above-mentioned figure: bobbin cradle 1, cylinder yarn 2, Wound-up roller 3, rotating shaft 4, stage clip 5, top board 6, girder 7, holder yarn bar 8.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail:
As shown in Figure 1 be the auxiliary pressure device of the bobbin cradle of piecing device of rotor spinning machine while not needing to lift a tin yarn, it comprises: bobbin cradle 1, cylinder yarn 2, Wound-up roller 3, rotating shaft 4, stage clip 5, top 6 and girder 7, on the bobbin cradle 1 of 4 rotations around the shaft, a yarn 2 is installed, this yarn 2 contacts with Wound-up roller 3, one end of stage clip 5 is fixed on top board 6, this top board 6 is connected with the girder 7 of rotor spinning machine, and the other end is free end.This stage clip 5 is for when cylinder yarn 2 diameters increase, and when increasing the pressure of cylinder yarn 2 and Wound-up roller 3 and cylinder yarn 2 joints and falling, dwindles the time that a yarn 2 falls.
When in spinning process, the diameter of cylinder yarn 2 is large from little change, bobbin cradle 1 is also along with rotating shaft 4 rotates to the B place from A, when the diameter of cylinder yarn 2 is increased to a certain degree, bobbin cradle 1 can touch stage clip 5, and when the diameter that continues to increase cylinder yarn 2, stage clip 5 can apply downward power to bobbin cradle 1, increase the pressure of cylinder yarn 2 and Wound-up roller 3, guarantee yarn quality.
As shown in Figure 2 be the auxiliary pressure device of the bobbin cradle of piecing device of rotor spinning machine need lift a tin yarn time, when in spinning process, the diameter of cylinder yarn 2 is large from little change, bobbin cradle 1 also rotates to the B place along with rotating shaft 4 from A, when needing joint, when holder yarn bar 8 holds up cylinder yarn 2, after joint completes, because bobbin cradle 1 contacts with stage clip 5, bobbin cradle 1 is applied to downward power, accelerate the fall time of cylinder yarn 2.
Stage clip 5 in the present embodiment can be replaced with conventional pneumatic fitting or other pressue device, when as long as described pneumatic fitting or other pressue device can be realized increasing the pressure of cylinder yarn 2 and Wound-up roller 3 and cylinder yarn 2 joints and fall, the function of dwindling the time that a yarn 2 falls gets final product.
