Description

Weft yarn conveyer Technical Field The application relates to the technical field of spinning, in particular to a weft yarn conveyor. Background During the weaving process, the weft yarn in the weft yarn cylinder needs to be unreeled and conveyed to be sent into a subsequent loom for weaving work. At present, in the weft unreeling and conveying process, the weft is usually drawn and unreeled by adopting passive traction, the tension of the weft is easy to be unstable in the conveying process, and the weft is not easy to be compensated and regulated in time, so that the subsequent spinning effect is seriously influenced. In addition, in the prior art, the tension adjustment of weft yarn conveying is mostly in a single-point mode, the response is delayed, the synchronous buffering of multiple points cannot be realized, and the stability and the textile quality of weft yarn conveying are further affected. Disclosure of Invention In order to adaptively adjust the tension of weft yarns, so that the tension of the weft yarns can be kept stable to ensure the subsequent spinning effect, the application provides a weft yarn conveyor. The application provides a weft yarn conveyor which adopts the following technical scheme: The weft yarn conveyor comprises a conveying base frame, a weft yarn drum, an unreeling motor, a first roller, a second roller and a third roller, wherein the weft yarn drum is horizontally rotatably arranged at the top position of the conveying base frame and is driven to rotate and unreel through the unreeling motor, the first roller and the second roller are both arranged at the top position of the unreeling frame, the third roller is arranged below the first roller and the second roller and between the first roller and the second roller, a water tank is arranged in the conveying base frame, a lower wheel frame is arranged at the top of the water tank, the third roller is arranged on the lower wheel frame through a wheel seat and can be vertically movably arranged, a sensor is further arranged on the lower wheel frame and used for detecting the height position of the third roller, a weight plate is further hung on the third roller through a hanging rope, and the weight plate is hung in the water tank. Through adopting above-mentioned technical scheme, in weft yarn transportation process, when the tension of weft yarn is too big, the third gyro wheel is pulled and is moved up, and the sensor can feed back the positional information of third gyro wheel to the unreeling motor this moment, makes the unreeling motor can control the unreeling speed of weft yarn to adjust the tension of weft yarn. Similarly, when the tension of the weft yarn is too small, the third roller is pulled to move downwards under the action of the weight plate, and the sensor can feed back the position information of the third roller to the unreeling motor, so that the unreeling motor can control the unreeling speed of the weft yarn to adjust the tension of the weft yarn, so that the tension in the weft yarn conveying process is adaptively adjusted, and the tension of the weft yarn can be kept stable, so that the follow-up spinning effect is ensured. In addition, when the third roller is pulled to move upwards due to overlarge weft tension, the weight plate moves upwards along with the third roller, and the weight plate receives water resistance in the upward moving process, so that the third roller can move upwards in a buffering mode, the third roller is not easy to fluctuate in tension to fluctuate suddenly, and stability adjustment of the follow-up unreeling motor on weft tension is further guaranteed. Similarly, when the third roller is pulled to move downwards due to too small weft tension, the weight plate moves downwards along with the third roller, the weight plate receives water resistance in the upward moving process, and the weight plate also receives water resistance in the downward moving process, so that the third roller can move downwards in a buffering mode, and stability adjustment of the subsequent unreeling motor to weft tension is further guaranteed. Optionally, the first roller and the second roller are detachably mounted on the conveying base frame. By adopting the technical scheme, the first roller, the second roller and the conveying base frame are detachably mounted, so that the first roller, the second roller and the conveying base frame are convenient to detach and replace. The lower wheel frame comprises two L-shaped vertical plates, the two L-shaped vertical plates are oppositely arranged, strip-shaped grooves extending vertically are formed in the two L-shaped vertical plates, a wheel seat is arranged between the two L-shaped vertical plates, two ends of the wheel seat are respectively and slidably arranged in the two strip-shaped grooves, the third roller is rotatably arranged on the wheel seat, the counterweight plate is hung on the wheel seat through a lifting rope, a guide hole is formed in
