Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: the device comprises a machine frame 1, a yarn bobbin 2, a friction wheel 3, a damping belt 4, a guide wheel 5, a tension wheel 6, a sliding seat 7, an elastic driving piece 8, an adjustable telescopic rod 9 and a bend wheel 10.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws within the scope of the claims of the present invention.
Example (b): as shown in fig. 1, the pay-off device of a trademark tape weaving machine comprises a frame 1, a yarn shaft 2 and a guide wheel 5, wherein the yarn shaft 2 is arranged on the frame 1, and the yarn shaft 2 can freely rotate and is used for sleeving a yarn coil. A friction wheel 3 is installed at one end of the yarn shaft 2, a damping belt 4 is arranged on the friction wheel 3, and the damping belt 4 is wound on the surface of the friction wheel 3. One end of the damping belt 4 is fixed on the frame 1, and the other end is connected with the sliding seat 7 after passing through the bend wheel 10. The direction-changing wheels 10 are provided in plurality, in the embodiment, the number of the direction-changing wheels 10 is two, one of the direction-changing wheels 10 is provided above the yarn shaft 2, the other direction-changing wheel 10 is provided above the tension wheel 6, and both the direction-changing wheels 10 can rotate freely.
A tension wheel 6 which can rotate freely is arranged on the slide seat 7, and the tension wheel 6 is positioned between the yarn shaft 2 and the guide wheel 5. The frame 1 is provided with vertical slide rails, the slide rails are positioned at the left side and the right side of the slide base, and the slide base 7 is installed on the two slide rails and moves up and down along the slide rails.
The slide seat 7 is connected with an elastic driving piece 8, and the elastic driving piece 8 is positioned below the tension wheel 6. The elastic driving part 8 is a tension spring, one end of the tension spring is fixed on the frame 1, and the other end of the tension spring is fixed on the sliding seat 7. The slide 7 is driven by the spring force of the tension spring to move in the direction of stretching the damping belt 4, i.e., downward.
The fixed end of the damping belt 4 is connected with a tension adjusting mechanism which is arranged above the friction wheel 3. The tension adjusting mechanism comprises an adjustable telescopic rod 9, the adjustable telescopic rod 9 comprises a threaded sleeve and two screw rods, the two screw rods are respectively screwed at two ends of the threaded sleeve, the end part of one screw rod is fixed on the rack 1, and the end part of the other screw rod is connected with the damping belt 4.
In the embodiment, when the yarn is drawn and paid off, the drawn yarn is tensioned due to the friction action of the friction wheel 3 and the damping belt 4. When the tension is too large, the force of the yarn acting on the tension wheel 6 overcomes the elastic force of the tension spring, so that the tension wheel 6 moves upwards, the damping belt 4 becomes loose relatively, the friction force between the friction wheel 3 and the damping belt 4 becomes small, and the yarn spool rotates more easily, so that the tension of the yarn becomes small. When the tension of the yarn is too small, the tension spring pulls the tension pulley 6 to move downwards, the damping belt 4 is tensioned, the friction force between the friction wheel 3 and the damping belt 4 is increased, the yarn shaft is not easy to rotate, and therefore the tension of the yarn is increased.
