The horizontal shaft take-up of centralized-control type
Technical field
The present invention relates to the metal working machinery field, be specifically related to the horizontal shaft take-up of a kind of centralized-control type.
Background technology
At present, most being magnetic clutch or coming tension force is controlled adjustment of adopting of the control of take-up winding tension in the domestic similar industry with operator's sensation and experience, though magnetic clutch can satisfy the requirement of degree of automation, but after the frequent start-stop will wear and tear and increase the weight of in the copper ring surface, thereby the switching reliability of power-transfer clutch is reduced, cause the output torque fluctuation, bigger variation takes place in the takeup tension that causes the steel cord, steel wire can cause sleave or fracture of wire in rolling, directly influence the quality of steel cord, cause serious waste.
Summary of the invention
The invention provides the horizontal shaft take-up of a kind of centralized-control type, solved the uppity problem of take-up winding tension.
For achieving the above object, by the following technical solutions:
The horizontal shaft take-up of a kind of centralized-control type, comprise take-up axle, Receiving wire wheel, bus cable device, traction wheel and axis of traction, pass through the transmission of pneumatic clutch slippage between the take-up sprocket wheel on described axis of traction and the take-up axle, described bus cable device is by the variable frequency reducer motor transmission, is connected by winding displacement gear, winding displacement rack driven between traverse shaft and the bus cable device.
As further preferred version, the described bus cable device outside is equipped with protection switch, and installed inside has near switch.
Compact conformation of the present invention; be easy to realize; by replacing traditional magnetic clutch with pneumatic clutch; control the tension force of steel wire by the air pressure of pneumatic clutch; traverse shaft and bus cable device are in transmission connection by rack-and-gear, and protection switch are installed and near switch on bus cable device, make takeup tension constant obtain effective control; and make that arranging of steel wire is more even, improved production efficiency and product quality.
Description of drawings
According to embodiment and accompanying drawing the present invention is described in further detail below.
Fig. 1 is the present invention, overall structure scheme drawing;
Among the figure:
1, take-up axle; 2, Receiving wire wheel; 3, winding displacement tooth bar; 4, winding displacement gear; 5, bus cable device; 6, traverse shaft; 7, traction wheel; 8, axis of traction; 9, pneumatic clutch; 10, protection switch; 11, near switch; 12, take-up sprocket wheel.
The specific embodiment
As shown in Figure 1; provided a specific embodiment of the present invention; Receiving wire wheel 2 is installed on the take-up axle 1 among the figure; take-up sprocket wheel 12 is installed on the take-up axle 1; pneumatic clutch 8 is installed on the axis of traction 7; axis of traction 7 passes through the transmission of pneumatic clutch slippage with take-up sprocket wheel 12; the middle part of take-up is equipped with bus cable device 5; bus cable device 5 is in transmission connection by winding displacement tooth bar 3 on the bus cable device 5 and the winding displacement gear 4 on the traverse shaft with traverse shaft 6; and bus cable device 5 is by the variable frequency reducer motor transmission; sway by winding displacement tooth bar 3 drives bus cable device 5 sway; steel wire is arranged evenly, in bus cable device 5 outsides protection switch 10 is installed, installed inside has near switch 11; control the moving range of bus cable device 5, prevent fault.
In steel cord take-up winding process, increase gradually along with the take-up coil diameter, Receiving wire wheel 2 increases with the angular velocity difference of traction wheel 7, takeup tension also progressively strengthens, at this moment, pneumatic clutch 9 can change the take-up rotating speed by the friction force size that changes friction lining, thereby retention wire speed and takeup tension are constant.Axis of traction and traction electric machine use synchronous pulley and synchronous belt drive, guarantee the revolution unanimity of each traction wheel, thereby guarantee the take-up speed unanimity.Bus cable device 5 along with winding displacement tooth bar 3 sway, thereby makes the steel cord by winding displacement gear 4 and 3 engagements of winding displacement tooth bar uniformly on Receiving wire wheel 2.
Compact conformation of the present invention; be easy to realize; by replacing traditional magnetic clutch with pneumatic clutch 9; control the tension force of steel wire by the air pressure of pneumatic clutch 9; traverse shaft 6 and bus cable device 5 are in transmission connection by rack-and-gear, and protection switch 10 are installed and near switch 11 on bus cable device 5, make takeup tension constant obtain effective control; and make that arranging of steel wire is more even, improved production efficiency and product quality.
