Problems solved by technology

In actual operation, the tension of the elastic webbing is maintained within a general range by setting the counterweight by the operator. This method has two shortcomings. One is that the tension of the entire elastic webbing does not change slowly, but Jumping, one section is large and one section is small; the second is that different operators have different judgments on tension, which leads to large differences in the tension of the belts woven by different operators, and the product quality is low.

Embodiment Construction

[0015] refer to figure 2 , image 3 , Figure 4 , the embodiment provides a tension control device for elastic uncoiling, which includes a frame 1, a pan head 2, a swing roller 3, a fixed roller 4, a brake wheel 5, a brake band 6, a spring 7, two swing arms 8, a rotating arm9. The cross-section of the pan head 2 is an inverted "I"-shaped structure, and the concave part in the middle is used to wind the rubber band. Applying a pulling force on the end can drive the pan head 2 to rotate against the frictional force of the rolling bearing to complete the uncoiling process of the elastic band. The frame 1 is provided with two support arms 11, the two support arms 11 are perpendicular to the axis of the central axis of the pan head 2 and are respectively located on the frame 1 at the axial ends of the pan head 2. The two swing arms One end of 8 is respectively hinged to the far-end of these two support arms 11, and described swing roller 3 is rotatably arranged on the non-hing...

Abstract

The present invention provides a tension control device capable of ensuring that the tensile force is nearby constant value. Said tension control device includes the following several portions: machine frame and warp beam flange, vibrating roller, fixed roller, brake wheel, brake-and-clutch lining, spring, two swinging arms and rotary arm which are placed on the machine frame and tension regulation device. Besides, said invention also provides the working principle of said tension control device and its concrete operation method.

Description

technical field [0001] The invention relates to a tension control device, which is used to control the tension of fabrics such as elastic or non-elastic fibers and yarns during the unwinding process. Background technique [0002] Tension control devices mainly include mechanical tension controllers, electronic tension controllers, and magnetic flux tension controllers. For example, the Chinese patent CN2251566Y announced on April 9, 1997 discloses an electronic tension controller, which detects pressure changes in real time through a tension detection device and feeds back to the electrical control system to finally keep the tension within a set range. Tension control devices are needed in many occasions in the chemical fiber weaving industry. For example, in the production process of elastic webbing, after the elastic warp is unrolled, the tension must be controlled within the set range through the tension control device, so as to ensure the tension of the entire elastic we...
