Then with lathe process and guarantee the concentricity of paper drawing roller shaft head Yu paper drawing roll surface, entire maintenance time takes around 2-3 days, sternly
Being normally carried out for production process is affected again.
Utility model content
The purpose of this utility model is exactly to provide a kind of for face-cloth to overcome the problems of the above-mentioned prior art
The master pull unit of paper machine.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of master pull unit for Face tissues machine, the device are arranged on Face tissues machine ontology, and the device includes
The vee-pulley and be plugged in vee-pulley that the driving mechanism and driving mechanism being arranged on Face tissues machine ontology are sequentially connected
In paper drawing roll shaft, be fixedly connected between the paper drawing roll shaft and vee-pulley using thread connecting mode.Driving mechanism drives three
Belt pulley rotation, vee-pulley transmit torque by thread fiting mode and paper drawing roll shaft are driven to rotate synchronously.
Further, paper drawing roll shaft jack is axially offered at the center of the vee-pulley along vee-pulley, it is described
One end of paper drawing roll shaft be plugged in paper drawing roll shaft jack.
Further, the inner wall of the paper drawing roll shaft jack is equipped with internal screw thread, and one end of the paper drawing roll shaft is set
There is external screw thread compatible with internal screw thread, the vee-pulley is fixedly connected by internal screw thread, external screw thread with paper drawing roll shaft.
The rotation direction of the direction of rotation and vee-pulley of the external screw thread and internal screw thread as a preferred technical solution,
It is identical.Since vee-pulley is, when vee-pulley rotates clockwise, to select orthodontic (dextrorotation) screw thread as follower, make three
It is consistent that the rotation direction of belt pulley and screw thread screw direction, to guarantee that vee-pulley and paper drawing roll shaft during rotation will not pines
It is de-.
Further, the internal screw thread and external screw thread are fine thread.In the selection of screw thread, in order to guarantee triangle
The running smoothly of belt wheel, bearing capacity need and the composite factors such as self-locking performance, final choice fine thread.
Further, the paper drawing roll shaft is equipped with belt wheel axial direction limited block compatible with vee-pulley.In order to keep away
Exempt from vee-pulley and feed motion occur on paper drawing roll shaft, by the way that belt wheel axial direction limited block is arranged, to vee-pulley it is axial into
Row limit guarantees reliable and stable when device works.
Further, the driving mechanism includes the driving wheel being arranged on Face tissues machine ontology, is wound around driving wheel
V-belt between vee-pulley and the driving wheel driving motor being connect with capstan drive.Driving wheel driving motor drives
Driving wheel rotation, driving wheel drive vee-pulley to rotate by V-belt.
Further, V-belt compatible with V-belt card slot is offered on the vee-pulley.V-belt card slot
Convenient for fixed triangle band, V-belt is enable steadily vee-pulley to be driven to rotate.
The utility model is in practical application, driving wheel driving motor passes sequentially through driving wheel, V-belt drives V-belt
Wheel rotation, while vee-pulley drives paper drawing roll shaft to rotate synchronously by being threadedly engaged, and realizes paper drawing movement.
Compared with prior art, the utility model has the characteristics that：
1) connection type between paper drawing roll shaft and vee-pulley is changed to thread connecting mode, avoids key connection mode
The problem of draw rollers shaft key groove present in transmitting torque wears and key is caused to loosen, improves product quality, reduces equipment
Failure rate has saved maintenance of equipment expense, good reliability；
2) only existing master pull unit need to slightly be changed, production easy to process is suitable for popularization and application.
