Description

Technical Field

[0001] The utility model belongs to the technical field of special textile equipment, and in particular relates to a double-motor winding mechanism for winding yarns on a sizing machine head. Background Art

[0002] The sizing machine is used to size yarn to increase yarn strength and reduce hairiness. The yarn on the warp creel is introduced into the sizing tank for sizing and drying. Finally, it is wound into a weaving beam and woven on a loom. The device for fixing and driving the weaving beam is installed on the head of the sizing machine.

[0003] A conventional loom-beam winding device includes a driving trolley, a passive trolley, an active chuck, a passive chuck, and a main drive motor that drives the active chuck to rotate. The active chuck is rotatably connected to the driving trolley, and the passive chuck is rotatably connected to the passive trolley. The loom is clamped between the active and passive chucks. The main drive motor drives the active chuck to rotate, thereby driving the loom to rotate and wind the yarn. Because the rotation of the loom is driven only by the active chuck at one end, and the loom has a large axial length, the loom generates a torsion angle at both ends during rotation, affecting the winding synchronization of the yarn at both ends of the loom, resulting in a difference in yarn tension at both ends of the loom, which affects the sizing quality. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a dual-motor winding mechanism for winding yarns of a sizing machine head, so as to solve the technical problem that one end of a conventional sizing machine head drives a weaving shaft, causing twisting of the two ends of the weaving shaft and thus affecting the difference in yarn tension at both ends of the weaving shaft.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The dual-motor winding mechanism for yarn winding at the head of the sizing machine includes a main trolley and an auxiliary trolley arranged relatively to each other. The main trolley and the auxiliary trolley are connected to active chucks for rotation one by one. The two active chucks are coaxial and symmetrically arranged. The two active chucks are used to clamp the active weaving shaft sleeves at both ends of the weaving shaft. The main trolley is provided with a main drive motor that drives the corresponding active chuck to rotate, and the auxiliary trolley is provided with an auxiliary drive motor for driving the corresponding active chuck. The main drive motor and the auxiliary drive motor are electrically connected to the same controller and are controlled by the controller.

[0007] As a preferred solution, the main drive motor and the auxiliary drive motor are both servo motors or variable frequency motors. The main drive motor and the auxiliary drive motor are respectively connected to the power supply through a motor driver. The control ends of the two motor drivers are connected in parallel and connected to an output end of the controller. The controller controls the two motor drivers to run synchronously, thereby controlling the main drive motor and the auxiliary drive motor to work synchronously.

[0008] As a preferred solution, the main drive motor and the auxiliary drive motor are both servo motors or variable frequency motors. The main drive motor and the auxiliary drive motor are respectively connected to the power supply through a motor driver, and the control ends of the two motor drivers are respectively connected to the two output ends of the controller. The controller controls the operation of the two motor drivers respectively to adjust the speed of the main drive motor and the auxiliary drive motor so that the main drive motor and the auxiliary drive motor are synchronized.

[0009] As a preferred solution, the current detection terminals of the two motor drivers, which are variable frequency drivers or servo drivers, are electrically connected to the two input terminals of the controller respectively.

[0010] As a preferred solution, the active chuck includes a disc head and a rotating shaft, the disc head is fixedly connected to one end of the rotating shaft, and the rotating shaft is rotatably connected to the corresponding main trolley or auxiliary trolley. A transmission shaft arranged parallel to the rotating shaft is rotatably connected in the main trolley and the auxiliary trolley. The transmission shaft on the main trolley is connected to the rotating shaft in the main trolley through a set of gear transmission pairs, and the transmission shaft on the auxiliary trolley is connected to the rotating shaft on the auxiliary trolley through another set of gear transmission pairs. The main drive motor is connected to the drive shaft on the main trolley through a belt, and the auxiliary drive motor is connected to the drive shaft on the auxiliary trolley through another belt.

[0011] The beneficial effect of the utility model is that the utility model provides driving force to both ends of the weaving shaft at the same time when the head of the sizing machine drives the weaving shaft to rotate, by respectively arranging active chucks and a main driving motor and an auxiliary driving motor for driving the two active chucks to rotate on the main trolley and the auxiliary trolley, so that the two ends of the weaving shaft rotate synchronously, eliminating the technical problem of twisting of the two ends of the weaving shaft.

[0012] The utility model further improves the synchronization of the main drive motor and the auxiliary drive motor by improving the control circuit of the main drive motor and the auxiliary drive motor, thereby improving the consistency of the driving speed and driving force at both ends of the weaving shaft, and further eliminating the torsion problem at both ends of the weaving shaft caused by the lack of synchronization between the main drive motor and the auxiliary drive motor.

[0020] In this embodiment, the main drive motor 6 and the auxiliary drive motor 7 are both variable frequency motors. Figure 2 As shown, the main drive motor 6 and the auxiliary drive motor 7 are respectively connected to the power supply through a motor driver 9. The control ends of the two motor drivers 9 are connected in parallel to an output end of the controller 8. The controller 8 controls the two motor drivers 9 to run synchronously, thereby controlling the main drive motor 6 and the auxiliary drive motor 7 to work synchronously.

[0021] The motor driver 9 in this embodiment is a variable frequency driver.

[0022] In practical applications, the main drive motor 6 and the auxiliary drive motor 7 may also be servo motors, and in this case the motor driver 9 is a servo driver.

[0023] like Figure 1 As shown, the active chuck 3 in this embodiment includes a disc head 301 and a rotating shaft 302, the disc head 301 is fixedly connected to one end of the rotating shaft 302, and the rotating shaft 302 is rotatably connected to the corresponding main trolley 1 or auxiliary trolley 2, and the main trolley 1 and the auxiliary trolley 2 are both rotatably connected with a transmission shaft 10 arranged parallel to the rotating shaft 302, the transmission shaft 10 on the main trolley 1 and the rotating shaft 302 in the main trolley 1 are connected by a set of gear transmission pairs 11, and the transmission shaft 10 on the auxiliary trolley 2 and the rotating shaft 302 on the auxiliary trolley 2 are connected by another set of gear transmission pairs 11.

[0024] The output shafts of the main drive motor 6 and the auxiliary drive motor are both connected to driving pulleys, one end of the two transmission shafts 10 extends out of the main trolley 1 or the auxiliary trolley 2 and is connected to a passive pulley, the main drive motor 6 is connected to the transmission shaft 10 on the main trolley 1 through a belt 12, and the auxiliary drive motor 7 is connected to the transmission shaft 10 on the auxiliary trolley 2 through another belt 12.

Example 2

[0026] The dual-motor winding mechanism for winding the yarn of the sizing machine head described in this embodiment is structurally the same as that of embodiment 1, and the only difference is that the control circuits of the main drive motor 6 and the auxiliary drive motor 7 are different.

The controller 8 can fine-tune the output power of the main drive motor 6 and the auxiliary drive motor 7 based on the difference in the operating current of the main drive motor 6 and the auxiliary drive motor 7, so that the workload of the main drive motor 6 and the auxiliary drive motor 7 tends to be consistent, that is, the operating current of the main drive motor 6 and the auxiliary drive motor 7 detected by the current sampling circuit 11 tends to be consistent. This can further improve the consistency of the driving force applied to the two ends of the weaving beam 4, thereby further eliminating the problem of torsion caused by the different driving forces applied to the two ends of the weaving beam 4.
