Detailed Description
The invention provides a plastic circular weaving machine, as shown in figures 1 and 2, comprising a main machine 1, wherein the main machine 1 is provided with a driving motor 2, a main shaft 3, a door ring component 4, a shuttle 5, a lifting device and a control system, the driving motor 2 is controlled by the control system, the driving motor 2 is in transmission connection with the main shaft 3, the door ring component 4 forms a runway for the circular operation of the shuttle 5, the main shaft 3 rotates to drive the shuttle 5 to move, a weft yarn spindle 51 is arranged on the shuttle 5, a first detector 52 for monitoring the rotation state of the weft yarn spindle 51 is arranged on the shuttle 5, the first detector 52 sends a first detection signal to the control system, a second detector 11 for monitoring the circular operation state of the shuttle 5 is arranged on the main machine 1, the second detector 11 sends a second detection signal to the control system, the control system controls the lifting speed of the lifting device according to the first detection signal or the second detection signal and controls the rotating speed of the main shaft 3 according to the second detection signal, when the first detection signal and the second detection signal are all normal, the control system controls the lifting speed of the lifting device to be reduced by X/2N, X is larger than or equal to 1 and smaller than or equal to N, when the second detection signal is abnormal, the control system controls the lifting speed of the lifting device to be reduced or increased in an equal proportion according to the circumferential running speed of the shuttle 5, namely the running speed of the shuttle 5 is reduced, the lifting speed of the lifting device is reduced in an equal proportion, and the running speed of the shuttle 5 is increased in an equal proportion.
According to the invention, whether the weft is used up or the weft is disconnected is monitored by the first detector 52, once the weft is used up or disconnected, an abnormal first detection signal is sent to the control system, at the moment, the control system does not directly control the main machine 1 to stop, but controls and reduces the lifting speed of the lifting device, because the wefts of other shuttles 5 are normally unwound, the plastic circular weaving machine can normally weave, only the number of the wefts is reduced, and therefore, the lifting speed of the lifting device is correspondingly reduced by the proportion of the reduced number of the wefts to the total number of the wefts, the situation that the weft is thin when the weft is finished or broken can be effectively avoided, and the weaving quality is ensured. When the driving motor 2 drives the spindle 3 to rotate, the transmission structure possibly breaks away from the spindle 3 and leads to the speed reduction until the shutdown, at the moment, the second detector 11 monitors the circumferential running state of the shuttle 5, the second detection signal can be abnormal, and the control system judges the rotating speed reduction of the shuttle 5, so that the lifting speed of the lifting device is controlled according to the circumferential running speed of the shuttle 5 to be reduced in an equal proportion, the lifting is stopped until the shutdown, and the condition of the weft thread with thin grade is effectively avoided. And because the weight of the weft spindle 51 will decline gradually in the use process, the weight of the shuttle 5 also declines, if the output power of the host machine 1 keeps unchanged, after the load of the main shaft 3 declines, the rotating speed of the shuttle 5 will accelerate gradually, at this moment, if the lifting speed of the lifting device keeps unchanged, the weaving speed of the weft is faster than the conveying speed of the warp, thereby the situation of over-dense weaving occurs, therefore, the circumferential running state of the shuttle 5 is monitored by the second detector 11, if the running speed of the shuttle 5 is accelerated, the lifting speed of the lifting device can be controlled to be improved in equal proportion, the uniform weaving is ensured, and the weaving efficiency can be improved. For woven bags for containing powder materials such as cement and the like, the sealing position needs to be subjected to encryption treatment to ensure that edges are not easy to break, and the problem of spraying cement at the sealing position can be effectively solved by controlling and accelerating the rotating speed of the main shaft 3 or reducing the lifting speed of the lifting device to realize the encryption weaving at the sealing position.
Because the weaving efficiency is influenced by too many weft yarns after completing or breaking weft yarns, considering that certain weaving efficiency is ensured, the machine needs to be stopped after the lifting speed of the lifting device is reduced to a certain degree, so that the time difference from starting the machine to stopping completely can be effectively shortened, and the condition that the weft yarns are in a thin gear during the stopping process is effectively avoided. In the existing production mode, generally one worker attends to about 5 plastic circular weaving machines, and in order to enable the worker to know in time after stopping, the control system can give an alarm after the lifting speed of the lifting device is reduced 1/2.
