The utility model relates to the textile machine technology, especially relates to and is used for the novel positive easing drive unit that warp tension is regulated on a kind of loom.
Background technology
In weaving process, the variation of the warp length that the opening owing to warp thread is produced, can carry out positive compensation by the active type steady device, to guarantee the stable of warp tension, and the positive easing drive unit is the power set of above-mentioned steady device, loose warp compensation when turning round in order to adapt to high-speed weaving machine is weaved highly dense and requirement heavily fabric to adapt to, and is provided with the positive easing drive unit on the loom mostly.Existing positive easing drive unit is many as shown in accompanying drawing 1 on the loom, the eccentric bushing 15 that employing has the banding mode is fastened on the driving shaft 1 by bolt 16, eccentric bushing bolt 11 is contained on the eccentric bushing 15, adjust the eccentric position of eccentric bushing bolt 11 by adjusting cover 14, then eccentric bushing bolt 11 is passed plain cushion 18 successively, eccentric mounting 13, plain cushion 18, nut 19 also links together, and be provided with needle bearing 17 between eccentric bushing bolt 11 and the eccentric mounting 13, eccentric mounting 13 is provided with the connecting rod that is connected with rocking bar, driving eccentric bushing 15 by driving shaft 1 rotates, drive eccentric bushing bolt 11 eccentric rotary, actuating sleeve is loaded on eccentric mounting 13 eccentric swings on the eccentric bushing bolt 11, swing by the connecting rod drive rocker, thereby realize the adjustment of offset, realize adjustment warp tension.But said apparatus complex structure, matching requirements precision height, this strengthens the difficulty of processing to eccentric bushing, reaches the matching requirements to the positive easing drive unit, improved requirement to a certain extent to assembling and maintenance personal's operative skill, and the operation and maintenance inconvenience of eccentric, fragile, axial carrying is poor, running accuracy is low, the variety renovation additional period is long when weaving, and has reduced the loom running efficiency, has increased and has weaved cost.
Summary of the invention
Technical problem to be solved in the utility model has provided a kind of running accuracy height, off-centre is easy to adjust and be convenient to the novel easily positive easing drive unit of mounting, commissioning and maintenance.
For solving the problems of the technologies described above, the technical solution of the utility model is: novel positive easing drive unit, comprise driving shaft and the eccentric disc seat that can be connected with rocking bar, and be set with eccentric disc in the described eccentric disc seat, the fixedly connected described driving shaft of described eccentric disc.
As a kind of improvement, be provided with ball bearing between described eccentric disc seat and the described eccentric disc.
As further improvement, described eccentric disc is set on the described driving shaft, described eccentric disc one side is provided with described driving shaft outer surface corresponding two and clamps the wing, described two clamp the wings extends axially and stretches out outside the described eccentric disc seat along described driving shaft, and described two clamp the wings is positioned at the outer part of described eccentric disc seat and is set with and is used for being fixed in eccentric disc clip on the driving shaft with clamping wing banding.
As further improvement, described rocking bar is provided with three location pin joints, is connected with length-adjustable adjusting connecting rod between one that three are located in the pin joint on described eccentric disc seat and the described rocking bar.
The novel positive easing drive unit of technique scheme, owing to be to have adopted driving shaft and the eccentric disc seat that can be connected with rocking bar, in the eccentric disc seat, be set with eccentric disc, the fixedly connected driving shaft of eccentric disc, simplified the structure of this device, improved reliability, it is convenient to be convenient to mounting, commissioning and maintenance, reduce difficulty of processing, improved economy.And the employing ball bearing, improved running accuracy, better to be adapted to high-speed weaving machine, simultaneously also can be suitable bear axial load, and allow suitable axial deviation during assembling, reduced requirement to assembling and maintenance personal's operative skill, and can be by selecting the bearing of suitable types for use, make bearing capacity obtain largely improving, make the control of loom positive easing compensation rate more stable, be suitable for weaving of highly dense heavily fabric.And employing banding structure, reduced to the processing request of eccentric bushing with to the matching requirements of positive easing drive unit, and the banding structure is simplified more, compactness, only need simultaneously to adjust angle stably by the degree of tightness of a screw, operation and maintenance to eccentric is convenient, cycle when having shortened variety renovation when weaving greatly, thus increased substantially the loom running efficiency, reduce and weave cost.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Fig. 1 is the scheme of installation of the novel positive easing drive unit of prior art;
Fig. 2 is a novel positive easing drive unit scheme of installation of the present utility model;
Fig. 3 is a novel positive easing drive unit fundamental diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the novel positive easing drive unit of prior art, the eccentric bushing 15 that employing has the banding mode is fastened on the driving shaft 1 by bolt 16, eccentric bushing bolt 11 is contained on the eccentric bushing 15, adjust the eccentric position of eccentric bushing bolt 11 by adjusting cover 14, then eccentric bushing bolt 11 is passed plain cushion 18 successively, eccentric mounting 13, plain cushion 18, nut 19 also links together, and be provided with needle bearing 17 between eccentric bushing bolt 11 and the eccentric mounting 13, and eccentric mounting 13 is provided with the connecting rod that is connected with rocking bar, driving eccentric bushing 15 by driving shaft 1 rotates, drive eccentric bushing bolt 11 eccentric rotary, actuating sleeve is loaded on eccentric mounting 13 eccentric swings on the eccentric bushing bolt 11, by the swing of connecting rod drive rocker, thereby the adjustment of realization offset realizes the adjustment to warp tension.But the said apparatus complex structure, matching requirements precision height, mounting, commissioning and maintenance inconvenience, the difficulty of processing height has reduced the loom running efficiency, has increased and has weaved cost.
