[0059] The output end of the cylinder 92 is connected to the tail of the cutting pliers 93, and is used to drive the cutting pliers 93 to extend or retract. When working, the main control unit drives the output end of the cylinder 92 to extend, and the output end of the cylinder 92 pushes the cutting pliers 93 forward and cuts the tow; then the main control unit drives the output end of the cylinder 92 to retract, and at the same time drives the cutting pliers 93 to move backward and return to the initial position, waiting for the next cycle of cutting work.

[0060] The main control unit is installed inside the support frame 1 and is electrically connected to the winding motor 82 , the cylinder 92 and the weighing sensor 4 respectively, so as to control the start and stop of the winding motor 82 and the cylinder 92 and obtain the weight information collected by the weighing sensor 4 in real time.

[0061] The main control unit generally selects a PLC controller, which can automatically control the winding motor 82 to realize the winding of the wire bundle, control the cylinder 92 to complete the cutting of the wire bundle, and cooperate with the weighing sensor 4 to realize the accurate weighing of the wire bundle, thereby replacing the traditional manual winding and weighing work. The whole process only requires manual loading, equipment operation, and manual unloading to complete the automatic winding and weighing work.

[0062] This embodiment also provides a protective cover 10 to control the flying dust generated during the winding process of the tow and improve the weighing accuracy. Specifically, the protective cover 10 is a transparent acrylic plate, which is installed on the base 3 and forms a protective space with the base 3. The winding assembly 8, the scissor assembly 9, and the weighing sensor 4 are all located in the protective space, and the wire support assembly is located outside the protective space.

[0063] A wire inlet 101 is provided on a side of the protective cover 10 close to the wire support assembly, and the size and height of the wire inlet 101 are adapted to the arc support 6 to ensure that the wire bundle can smoothly enter the winding assembly 8.

The operator can see the operation status of the equipment while physically isolating the running equipment and personnel, thereby improving the automation and safety of the system.

[0065] In order to improve the visualization of the winding weighing process and the precise control of the weighing process, the present embodiment further includes a control screen 11 placed on the workbench 2, which is connected to the main control unit and the weighing sensor 4 respectively, and is used to display the weighing information of the tow in real time.

[0066] In addition, this embodiment also provides a method for weighing a tow automatic winding, comprising the following steps:

[0067] Step [1]: Assemble the automatic winding weighing system of the tow of this embodiment and start the main control unit. Before this, the weight of a single weighing and the speed of the winding motor 82 and other information need to be set in advance. In addition, the control panel 11 and the weighing sensor 4 need to be powered on. The initial weight information displayed on the control panel 11 is generally "0g". If there is an error, click the "Reset to Zero" button (that is, reset the weight information initially collected by the weighing sensor 4 to zero).

[0068] Step [2], open the single door 102, take out the tow head from the tow sample barrel, pass it through the arc support 6, and fix it to one of the winding arms 85 through a clamp, and then close the single door 102.

[0069] Step [3]: The winding motor 82 is driven by the main control unit to work, and the winding motor 82 drives the winding shaft 84 and the winding arm 85 to rotate synchronously to wind the wire bundle. When the wound wire bundle reaches the predetermined weight, the winding motor 82 stops working. During this process, the control screen 11 will also display the weight of the wire bundle in real time. Then, the main control unit drives the cylinder 92 to work, and the output end of the cylinder 92 pushes the pliers 93 to move forward and cut the wire bundle. After that, the pliers 93 are reset under the drive of the cylinder 92, thereby realizing the winding and cutting of the predetermined weight of the wire bundle.

[0070] Step [4]: ​​open the single door 102 and remove the wound and weighed wire bundle from the wire winding arm 85, thus completing the automatic winding and weighing of the wire bundle. Then, the next cycle of winding and weighing can be completed according to the above steps.

[0071] This method is highly efficient and the weight of the yarn bundle is more accurate, which is more conducive to the next step of accurate testing and analysis.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
