Description

Spinning cake winding quality test platform

Technical Field

As shown in fig. 1 and 2, the embodiment discloses a cake winding quality testing platform, which comprises a first bracket 1, a second bracket 2, a controller, an active unwinding motor 3, a spinning motor 4, a roller 5 and a high-speed camera 6.

The first bracket 1 and the second bracket 2 are used as supporting structures for respectively installing an active unwinding motor 3 and a spinning motor 4 and other parts.

The active unwinding motor 3 is mounted on the first bracket 1 and is electrically connected with the controller, and an output shaft of the active unwinding motor 3 is used for being detachably connected with the spinning cake 17.

The filament drawing motor 4 is arranged on the second bracket 2 and is electrically connected with the controller.

The roller 5 is fixedly arranged on the output shaft of the spinning motor 4, and the silk thread 20 drawn from the silk cake 17 is wound around the roller 5.

The high-speed camera 6 is electrically connected with the controller to photograph in real time the balloon generated by the movement of the filament 20 during the filament drawing process.

The controller coordinates and controls the rotation speeds of the active unwinding motor 3 and the spinning motor 4 so as to realize synchronous operation of the active unwinding motor 3 and the spinning motor 4 according to test requirements, the controller can accurately control the rotation speeds of the active unwinding motor 3 and the spinning motor 4 so as to carry out spinning according to preset linear speeds, meanwhile, the linear speed difference can be stabilized by adjusting the real-time rotation speed difference of the unwinding motor and the spinning motor, the extraction force of the silk thread from a silk cake is further adjusted, and finally the form and the size of a balloon are reflected, and the silk thread tension is also reflected. Further description: when only low-speed spinning is needed, the spinning motor 4 can be controlled to rotate, when only high-speed spinning is needed, the spinning motor 4 and the active unwinding motor 3 are controlled to rotate simultaneously, the picture of the balloon shot by the high-speed camera 6 is compared with a preset picture (a picture shot in advance of a spinning cake 17 with excellent winding quality and shot during spinning at the speed), so as to judge whether the winding quality of the spinning cake 17 is good or bad, and if the shot picture of the balloon is consistent with or close to the preset picture, the winding quality of the spinning cake 17 is judged to be good or not.

Further, the cake winding quality testing platform of the present embodiment further includes a displacement sensor 7 electrically connected to the controller to detect the diameter of the cake 17 in real time, a first rotational speed sensor 18 electrically connected to the controller to detect the rotational speed of the active unwinding motor 3 in real time, and a second rotational speed sensor 19 electrically connected to the controller to detect the rotational speed of the spinning motor 4 in real time. Because the diameter of the spinning cake 17 can be continuously reduced in the spinning process, the displacement sensor 7 is arranged to be capable of detecting the diameter of the spinning cake 17 in real time, the first rotating speed sensor 18 and the second rotating speed sensor 19 are respectively used for detecting the rotating speed of the active unwinding motor 3 and the rotating speed of the spinning motor 4 and feeding detection signals back to the controller, so that the controller can be used for more accurately and cooperatively controlling the rotating speeds of the active unwinding motor 3 and the spinning motor 4, and the constant unwinding spinning linear speed is guaranteed.

In this embodiment, the electric lifting mechanism 8 can dynamically adjust the height or distance of the laser displacement sensor 7 according to the diameter change of the spinning cake 17. This design allows the displacement sensor 7 to be always kept in place for measurement, since the cake 17 will gradually decrease in diameter during unwinding. The laser displacement sensor 7 is used as a high-precision measuring tool, and can accurately detect the diameter change of the spinning cake 17. The electric lifting structure is electrically connected with the controller, so that automatic control can be realized, the change of the size of the spinning cake 17 can be adapted without manual intervention, and the degree of automation of the testing process is improved.

In this embodiment, the first guide hook 9 and the second guide hook 10 are provided to guide the thread 20 drawn from the cake 17, so as to ensure that the thread 20 moves along a predetermined path, and the thread 20 sequentially passes through the two guide hooks, so that the possibility of entanglement or dislocation of the thread 20 during the movement process can be reduced, and thus, the orderly unwinding of the thread 20 can be ensured.

Further, the spinning cake winding quality testing platform of the embodiment further comprises a rotating shaft 11 and an expansion sleeve type coupling 12. The expansion sleeve type coupling 12 is used for connecting the output shaft of the active unwinding motor 3 and the rotating shaft 11.

In this embodiment, the motor and the rotating shaft 11 can be simply and reliably connected by the expansion sleeve type coupling 12, so that dynamic unbalance caused by key slot design is avoided.

Further, the spinning cake winding quality testing platform of the embodiment further comprises a steel sleeve 13 and an expansion sleeve 14. The steel sleeve 13 is sleeved on the rotating shaft 11 in an interference fit mode. The expansion sleeve 14 is sleeved on the outer side of the steel sleeve 13.

During testing, the paper tube sleeve of the spinning cake 17 is fixed on the expansion sleeve 14, so that the outer diameter of the expansion sleeve 14 is changed according to the requirement, the spinning cake 17 with different sizes is assembled, and the applicability of the spinning cake winding quality testing platform of the embodiment is improved.

Further, the active unwinding motor of the present embodiment further comprises a rubber ring mounting sleeve 22, a support sleeve 21 and a bearing 23.

Further, the cake winding quality testing platform of the present embodiment further includes a guide rail 16. The first support 1 and the second support 2 are both slidably arranged on the guide rail 16, and the first support 1 and the second support 2 can be mutually close to or far away from each other along the guide rail 16, so that the distance between the active unwinding motor 3 and the filament drawing motor 4 can be flexibly adjusted according to the needs, the transverse filament drawing position is ensured, and the distance adjustment is conveniently carried out according to the variety and the speed of the measured filament.

The embodiment also discloses a spinning cake winding quality testing method, which uses the spinning cake winding quality testing platform, and comprises the following steps:

The spinning speed (linear speed) is set according to the test requirement, so that passive spinning and active unwinding spinning at different relative speeds can be realized.

The rotation speeds of the active unwinding motor 3 and the spinning motor 4 are coordinated and controlled by the controller according to the set spinning speed so as to realize spinning according to the spinning speed. In particular, the constant spinning linear speed only means that the spinning roller rotating speed is constant, and the real-time relative rotating speed of the unwinding motor and the spinning motor can be adjusted to conveniently adjust the tension of the silk yarn due to the time-varying change of the spinning cake diameter, so that the unwinding state under various environments can be conveniently tested.

The balloon generated by the movement of the yarn during the drawing process is photographed in real time by the high-speed camera 6.

The picture of the balloon taken by the high-speed camera 6 is compared with a preset picture.
