Description

Technical Field

[0001] The present application relates to the technical field of warping machines, and in particular to a device for detecting the thickness of yarn wound around a ball-diameter axis of a warping machine. Background Art

[0002] The warping machine collects the yarns from hundreds of yarn bobbins onto the warp beam. After the yarns are fully wound on the warp beam, they are used as raw yarns for the sizing machine. The warping machine collects the yarns from all the yarn bobbins onto the warp beam at different speeds according to the types of yarns. As the yarns are wound, the speed of the warp beam will gradually decrease as the diameter of the yarn roll continues to increase.

[0003] At present, when the warping machine is performing warping, it is usually required that the yarn winding diameter on the warp beam is within a certain range. The traditional measurement method is to install a photoelectric sensor at a fixed position on the warping machine, and trigger the photoelectric sensor through the edge of the yarn winding diameter on the warp beam to achieve control of the yarn winding diameter.

[0004] As the warp beam rotates, it will be affected by the vibration generated by the motor on the warping machine, causing the tension of the yarn to change, thereby causing the density of the yarn wound on the warp beam to change, so that the diameter of the yarn is not the same after the warp beam is wound the same number of times. Under the control of the same photoelectric sensor, the number of turns of the yarn wound on different batches of warp beams is different, resulting in inconsistent quality of the yarn wound on the warp beam, which is a deficiency. Utility Model Content

[0005] In order to improve the problem of different numbers of turns of yarn wound on a warp beam, the present application provides a device for detecting the thickness of yarn wound on a warping machine ball-diameter shaft.

[0006] The present application provides a device for detecting thickness of yarn wound around a warping machine ball diameter axis, which adopts the following technical solution:

[0007] A device for detecting the thickness of yarn wound on a ball-diameter shaft of a warping machine comprises a frame, on which a power roller is rotatably arranged, on which a driving member for driving the power roller to rotate is arranged, on which two lifting plates are slidably arranged on the frame, a ball-diameter shaft is mounted between the two lifting plates, the ball-diameter shaft is used for winding yarn, the ball-diameter shaft is pressed on the power roller, and on the frame a detection component for controlling the number of rotations of the ball-diameter shaft is arranged.

[0008] By adopting the above technical scheme, workers first wind the yarn on the ball diameter shaft, and then the ball diameter shaft presses the yarn onto the power roller. The driving member drives the power roller to rotate, and the power roller drives the ball diameter shaft to rotate through friction. The yarn wound on the ball diameter shaft will push the lifting plate to move vertically upward through the increased yarn diameter, and the gravity of the lifting plate and the ball diameter shaft presses the yarn wound on the ball diameter shaft, making the density of the wound yarn compact and reducing the influence of the vibration on the frame on the density of the wound yarn. Then, the number of turns of the ball diameter shaft is controlled by the detection component, so that the diameter of the yarn wound on the ball diameter shaft is the same, which is effective in improving the quality of yarn winding.

[0009] Optionally, the power roller includes a first unit roller and a second unit roller, the first unit roller and the second unit roller are symmetrically arranged about the ball diameter axis, and the first unit roller and the second unit roller are both provided with a friction layer.

[0010] By adopting the above technical scheme, the yarn wound on the ball diameter shaft is pressed against the first unit roller and the second unit roller. The friction layer reduces the possibility of the first unit roller or the second unit roller idling relative to the ball diameter shaft, and reduces the occurrence of the yarn wound on the ball diameter shaft bulging due to the idling of the first unit roller or the second unit roller. This is beneficial to increasing the density of the yarn wound on the ball diameter shaft to be the same. At the same time, the first unit roller and the second unit roller restrict each other, further reducing the occurrence of yarn bulging.

[0011] Optionally, the driving member includes a driving motor disposed on the frame and electrically connected to a control system, a synchronous belt is provided between the first unit roller and the second unit roller, and an output shaft of the driving motor is coaxially disposed on the first unit roller.

[0012] By adopting the above technical solution, workers start the drive motor through the control system. The output shaft of the drive motor drives the first unit roller to rotate, and at the same time drives the second unit roller to rotate through the synchronous belt, thereby achieving the effect of synchronous rotation of the first unit roller and the second unit roller, which is beneficial to improving the uniformity of the winding yarn density.

[0013] Optionally, the detection component includes a slider arranged on the lifting plate, a slide rail is arranged on the frame, the slider is slidably arranged on the slide rail, sprockets are rotatably arranged at both ends of the frame along the length direction of the slide rail, chains are wound around the two sprockets, both ends of the chain can be removably arranged on the slider, and a detection part for controlling the number of rotations of the sprocket is arranged on the frame.

[0014] By adopting the above technical scheme, as the diameter of the yarn wound on the ball diameter shaft continues to increase, the yarn drives the slider on the lifting plate to slide along the length direction of the slide rail through the ball diameter shaft, the slider moves and drives the sprocket to rotate through the chain, and then the detection part records the number of revolutions of the sprocket, thereby indirectly controlling the size of the winding diameter of the yarn on the ball diameter shaft, so that the control result of the diameter of the yarn wound on the ball diameter shaft is more accurate.

[0015] Optionally, the detection member includes a chain shaft coaxially arranged on one of the sprockets, an encoder is coaxially arranged on the chain shaft, and the encoder is electrically connected to the control system.

[0016] By adopting the above technical solution, the sprocket drives the rotating shaft of the encoder through the chain shaft, and the encoder feeds back information to the control system. When the number of turns designed by the encoder is reached, the control system stops supplying power to the drive motor and the ball diameter shaft stops rotating.

[0017] Optionally, two tensioning plates are rotatably provided on the frame, a tensioning roller is rotatably provided between the two tensioning plates, the tensioning roller is used to tension the yarn, the axis of the tensioning roller is parallel to the ball diameter axis, and a tensioning member for driving the tensioning plates to rotate is provided on the frame.

[0018] By adopting the above technical solution, as the diameter of the yarn wound on the spherical shaft continues to increase, the tensioning member drives the tensioning plate to rotate, and the tensioning plate drives the tensioning roller to rotate synchronously, changing the winding angle of the yarn on the spherical shaft, thereby adjusting the tension of the yarn during winding, which is beneficial to ensure that the density of the yarn wound on the spherical shaft tends to be consistent.

[0019] Optionally, the tensioning member includes a tensioning cylinder rotatably disposed on the frame, the tensioning cylinder is electrically connected to a control system, and a piston rod of the tensioning cylinder is rotatably disposed on the tensioning plate.

[0020] By adopting the above technical solution, the encoder feeds back the number of rotations of the sprocket to the control system, and the control system controls the tensioning cylinder. The piston rod of the tensioning cylinder drives the tensioning plate to rotate, thereby adjusting the tension of the tensioning roller on the yarn.

[0021] Optionally, a tension groove is provided on the tensioning plate, a tension block is slidably arranged in the tension groove, the tensioning roller is rotatably arranged on the tension block, a pressure sensor is arranged between the tension block and the tension groove, and the pressure sensor is electrically connected to the control system.

[0022] By adopting the above technical solution, when the tensioning plate drives the tensioning roller to rotate a certain angle, the tensioning roller squeezes the pressure sensor in the tension groove through the tension block, and the pressure sensor feeds back the pressure information to the control system, and the control system then reversely controls the tensioning cylinder to accurately control the tension of the yarn on the tensioning roller, thereby further improving the accuracy of controlling the diameter of the yarn wound on the ball diameter shaft.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The worker first winds the yarn around the ball-diameter shaft, and then the ball-diameter shaft presses the yarn onto the power roller. The driving member drives the power roller to rotate, and the power roller drives the ball-diameter shaft to rotate through friction. The yarn wound on the ball-diameter shaft will push the lifting plate to move vertically upward through the increased yarn diameter, and the gravity of the lifting plate and the ball-diameter shaft presses the yarn wound on the ball-diameter shaft, making the density of the wound yarn compact and reducing the influence of the vibration on the frame on the density of the wound yarn. Then, the number of turns of the ball-diameter shaft is controlled by the detection component, so that the diameter of the yarn wound on the ball-diameter shaft is the same, which is useful for improving the quality of yarn winding;

[0025] 2. The yarn wound on the ball-diameter shaft is pressed against the first unit roller and the second unit roller. The friction layer reduces the possibility of the first unit roller or the second unit roller idling relative to the ball-diameter shaft, and reduces the situation that the yarn wound on the ball-diameter shaft bulges due to the idling of the first unit roller or the second unit roller, which is conducive to increasing the density of the yarn wound on the ball-diameter shaft to be the same. At the same time, the first unit roller and the second unit roller restrict each other, further reducing the situation of yarn bulging;

[0026] 3. As the diameter of the yarn wound on the ball diameter shaft continues to increase, the yarn drives the slider on the lifting plate to slide along the length direction of the slide rail through the ball diameter shaft, the slider moves and drives the sprocket to rotate through the chain, and then the detection part records the number of turns of the sprocket, thereby indirectly controlling the size of the winding diameter of the yarn on the ball diameter shaft, making the control result of the diameter of the yarn wound on the ball diameter shaft more accurate.

The detection component 6 includes a slider 61 bolted to the lifting plate 4. A vertical slide rail 62 is bolted to the frame 1. The slider 61 is slidably arranged on the slide rail 62. Sprocket wheels 63 are rotatably arranged at both ends of the frame 1 along the length direction of the slide rail 62. A chain 64 is commonly wound around the two sprocket wheels 63.

A tension block 11 is slidably arranged in the tension groove 10, and a pressure sensor 12 is arranged between the tension block 11 and the tension groove 10. The pressure sensor 12 is electrically connected to the control system, and a tension roller 8 is rotatably mounted between the tension blocks 11 on the two tensioning plates 7.
