Abstract
The utility model discloses a tension bracket, which comprises a rack, wherein a drive roller, a driven roller and a motor for driving the drive roller are arranged on the rack, a tension sensor is arranged below the driven roller, the tension sensor is connected with a transducer through a signal, and the transducer is electrically connected with the motor. An actual tension value of a fabric is directly measured by the tension sensor, is fed back to the transducer in a signal manner, PID (Proportion Integration Differentiation) computing comparison is carried by comparing the signal with a preset tension value of the transducer, a control signal is output, the rotating speed of the motor is controlled, so that the actual tension value is equal to the preset tension value, thus the tension of the fabric can be accurately controlled.
Description
Technical field
The utility model relates to a kind of tension bracket, particularly a kind of tension bracket that is used to control the transmission fabric tension.
Background technology
At present, at the fabric transfer-ring tension controller of textile printing and dyeing industry, mainly adopt disk spring to promote the Friction disk transmission; Carry out fabric tension control, can't regulate friction force when this structure roll body rotates, the size of rotating torque is difficult to adjustment; The long-term pressurized of belleville spring certainly leads to fatigue deformation, and easy-to-rust damages; Diversion fee is high, and moment is difficult to reach technological requirement.
Chinese patent CN03155258.7 discloses a kind of fabric transfer-ring tension controller that adopts air operated control tension force; It comprises fabric guide roll, deflector roll axle sleeve, is located at sprocket wheel and bearing brackett that guide roller axis puts; It is characterized in that it also includes pneumatic shuttle, heat radiation sliding sleeve, heat insulating mattress, seal ring, friction lining, friction lining volume, piston rod one end in the pneumatic shuttle is fixing through being threaded with guide roller axis; The end face of the cylinder body of pneumatic shuttle axially contacts with the heat radiation sliding sleeve; Heat radiation sliding sleeve another side axially contacts with friction lining, and friction lining is located between deflector roll axle sleeve and the sprocket wheel end face, is provided with the friction lining volume in the sprocket hole.The shortcoming of this tension control assembly is the tension force of different accurately control fabrics.
The utility model content
The purpose of the utility model is the deficiency to prior art, and a kind of tension bracket that can accuracy control transmits fabric tension is provided.
For achieving the above object, the utility model is realized through following technical scheme:
Tension bracket comprises frame, and said frame is provided with the motor of drive roll, driven voller, driving drive roll, and said driven voller has tension pick-up, and said tension pick-up is connected with a frequency converter signal, and this frequency converter and said motor are electrically connected.
Further, be connected for sprocket wheel between said drive roll and the said driven voller.
Further, said driven voller quantity is six, is provided with a drive roll between two adjacent driven vollers.
Further, said frequency converter has manual control gear.
The beneficial effect of the utility model is: through tension pick-up is set, directly measure the actual tension value of fabric, then this tension value is fed back to frequency converter with signal form; Through this signal and the predefined tension value contrast of frequency converter; Carry out PID and calculate relatively, output control signal, control rotating speed of motor; The actual tension value is equated, tension force that thus can the accuracy control fabric with preset tension value.
Description of drawings
Fig. 1 is the structural representation of the utility model side.
The specific embodiment
For structure, characteristic and effect thereof to the utility model, can have and further understand and be familiar with, lift a preferred embodiment at present, and be described with reference to the accompanying drawings as follows:
As shown in Figure 1, the described tension bracket of the utility model comprises frame 1, and said frame is provided with 6 driven vollers 3, is provided with a drive roll 2 between two adjacent driven vollers 3, is connected for sprocket wheel between said drive roll 2 and the said driven voller 3.Said drive roll 2 is driven by motor 4, and said driven voller 3 has tension pick-up 5, and said tension pick-up 5 is connected with a frequency converter 6 signals, and this frequency converter 6 is electrically connected with said motor 4.Said frequency converter 6 has manual control gear 61.
During use, directly measure the actual tension value of fabric, then this tension value is fed back to frequency converter 6 with signal form by tension pick-up 5; Through this signal and frequency converter 6 predefined tension value contrasts; Carry out PID and calculate relatively, output control signal, the rotating speed of control motor 4; The actual tension value is equated, tension force that thus can the accuracy control fabric with preset tension value.
The above is merely the preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; Allly be familiar with this operator; The principle and the technical characterictic of utilization the utility model, various changes and the decoration done all should be covered by within the protection category that these claims define.
