DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-7 The present invention provides the following technical solution: a composite twisting machine, comprising a frame 1 and a double twisting machine 2, wherein a yarn inlet 11 is provided on the top of the frame 1, and the double twisting machine 2 comprises a tension disk control device 21 and a winding device 22, wherein the tension disk control device 21 comprises a tension disk 211, a drive shaft 212 and a tension disk motor 213, wherein the tension disk 211 is transmission-connected to the tension disk motor 213 through the drive shaft 212, wherein a yarn channel 2121 is provided in the drive shaft 212, wherein a yarn guide hole 2111 is provided on the tension disk 211, wherein the winding device 22 comprises a steel collar 221, a paper tube spindle 222, a winding motor 223 and a forming device 224, wherein the steel collar 221 is located below the tension disk 211, wherein a yarn guide hook 2211 is movably connected to the steel collar 221, and wherein the paper tube spindle 222 is located in the middle of the steel collar 221 and is connected to the paper tube spindle 222. The winding motor 223 is connected in transmission, and the forming device 224 can simultaneously drive the tension disk 211 and the steel collar 221 to move along the vertical direction of the frame 1. The forming device 224 includes a screw rod 2241, a fixed seat 2242 matched with the screw rod 2241, a connecting frame 2243 and a forming motor 2244. The connecting frame 2243 is fixedly connected with the tension disk 211 and the steel collar 221. The fixed seat 2242 is fixed to the side of the connecting frame 2243 facing away from the tension disk 211. The screw rod 2241 is located in the fixed seat 2242 and is connected in transmission with the forming motor 2244. An intelligent controller 12 is provided on the frame 1. The intelligent controller controls the rotation speed of the tension disk motor 213 and the winding motor 223 through a program to keep the phases of the tension disk motor 213 and the winding motor 223 consistent.

[0019] With the above structure, the yarn is put in from the yarn inlet 11, passes through the yarn channel 2121 in the drive shaft 212, passes through the yarn guide hole 2111 on the tension disk 211, and finally passes through the yarn guide hook 2211. After completing the above operations, the intelligent controller 12 is programmed or imported into the program. After the paper roll is placed on the paper roll spindle 222, the intelligent controller 12 sends a command to the frequency converter to control its output frequency so as to control the rotation speed of the tension disk motor 213 and the winding motor 223. The rotation speed is controlled by the program so that the yarn guide hole 2111 and the yarn guide hook 2211 are always kept at the same The vertical line can ensure that the relative position does not change, which can effectively prevent the yarn from being over-tensioned during re-twisting and causing yarn breakage, greatly improving the stability of the device during operation, greatly reducing the demand for labor, alleviating the burden on workers, and effectively improving production efficiency. The screw rod 2241 has high transmission efficiency, high transmission accuracy, and stable operation, which can ensure that the tension disk 211 and the steel collar ring 221 do not vibrate significantly when moving vertically, avoiding the phenomenon of yarn breakage. Therefore, this structure can greatly avoid unexpected phenomena in the transmission device and ensure its operational stability.

[0020] In this embodiment, the intelligent controller 12 is composed of a system controller and a frequency converter. The system controller is a PLC controller, which can be used for program execution. The frequency converter is used to control the rotation speed of the tension disk motor 213, the winding motor 223 and the forming motor 2244.

[0021] By adopting the above structure, different programs can be input or imported according to different needs in an open source manner. By setting the frequency converter, the consumption of electric energy can be reduced to achieve the technical purpose of energy saving. The rotation speed of each motor can also be accurately controlled. The system controller is a PLC controller, which is an existing publicly known technology product.

[0022] In this embodiment, a positioning slide block 22431 is disposed on the connecting frame 2243 , and a positioning slot 13 adapted to the positioning slide block 22431 is provided on the frame 1 .

[0023] With the above structure, the positioning slide groove 13 plays a role of limiting, preventing the lifting device from running overtravel and causing damage to the device, thereby playing a role of protecting the device.

[0024] In this embodiment, the yarn channel 2121 is divided into a yarn inlet 21211 and a yarn outlet 21212 . The yarn inlet is located at an end of the driving shaft 212 away from the tension disk 211 , and the yarn outlet 21212 is located between the motor and the tension disk 211 .

[0025] The above structure can effectively reduce the tension of the yarn during re-twisting, prevent contamination, and make it possible to observe the re-twisting situation more intuitively.
