Problems solved by technology

Although the yarn is subjected to centripetal pressure, it is impossible to shrink in its length direction and still maintain a large winding tension. Therefore, when the yarn elasticity is not good, some yarns will lose tension and relax and wrinkle, which affects the winding. Forming quality

Embodiment Construction

[0013] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0014] Such as figure 1 As shown, a constant tension control device for winding equipment includes a guide roller 20 that guides the yarn a to the winding head 10, and the winding diameter of the winding head 10 increases from small to large during winding. , by adjusting the winding head 10 to stabilize the tension of the yarn a, so the speed of the winding head 10 at different roll diameters is controlled and adjusted by the PLC controller; between the winding head 10 and the guide roller 20 A pressure sensor is arranged between them, and the yarn a derived from the guide roller 20 passes through the pressure sensor and is guided to the win...

Abstract

The invention relates to a constant-tension control device for a winding device. The constant-tension control device for the winding device comprises yarn guide rolls, wherein the yarn guide rolls are used for conveying yarn to a winding pan head in a guiding mode, the rotating speed of the winding pan head is controlled by a PLC and is adjusted through the PLC when different winding diameters are adopted, a pressure sensor is arranged between the winding pan head and the yarn guide rolls, the yarn which is led out through the yarn guide rolls penetrates through the pressure sensor and is conveyed to the winding pan head in the guiding mode, the output end of the pressure sensor is connected to the PLC, the winding pan head is driven by a winding motor to rotate, the winding motor is connected with a first frequency converter and an encoder, the first frequency converter and the encoder are connected to the PLC, and the frequency of the first frequency converter is controlled by the encoder through the PLC.

Description

technical field [0001] The invention relates to an auxiliary device of a coiling device, in particular to a device for controlling the constant tension during yarn coiling. Background technique [0002] Spinning is the process of processing textile fibers into yarns, and then weaving them into cloth. The so-called spinning is to take animal or vegetable fibers and use twisting methods to make them entangled into a continuous and infinitely extending yarn. , so as to apply a behavior of weaving. After the fiber is turned into yarn, the yarn needs to be regularly wound into packages of certain specifications by a coiler for transportation and use. The yarn has a certain winding tension in the package. The tension of the outer yarn causes its centripetal pressure on the inner yarn, and the centripetal pressure of the outer yarn causes the inner yarn to compress and deform. As a result, the winding density of the inner layer yarn increases, the yarn tension weakens, or eve...
