[0037] This invention provides a driving method for the movement of the pull roller in a combing machine, such as... Figure 1 - Figure 4As shown, a driving method for the movement of the pull roller 6 in a wool combing machine includes:
[0038] The active motion input is synthesized into two motions and then collaboratively drives the pull roller 6. This drive method overcomes the bottleneck of the existing "toothed belt and spring pressure" transmission method, which is difficult to adapt to the high-speed combing of wool combing machines, and is conducive to improving the production capacity and efficiency of wool combing machines.
[0039] Active motion includes first oscillation, unidirectional rotation, and second oscillation;
[0040] The steps for combining two motions are as follows:
[0041] S1, combine the first oscillation and the unidirectional rotation into a single composite motion;
[0042] S2 combines the first composite motion with the second oscillation to complete the two motion synthesiss.
[0043] This invention also discloses a driving device for the movement of the pull roller 6 in a combing machine, employing a driving method for the movement of the pull roller 6 in a combing machine, comprising:
[0044] A conjugate cam-linkage combination mechanism is used to output unidirectional rotation, first oscillation, and second oscillation.
[0045] Differential gear train, used to combine the first oscillation and unidirectional rotation into a single composite motion; and
[0046] A moving shaft gear mechanism is used to combine a primary composite motion and a second oscillation.
[0047] The conjugate cam and connecting rod assembly includes a crankshaft 1, which rotates and drives the planetary carrier gear 12 to rotate in one direction and the rocker arm 10 to swing; a conjugate cam 2, which is fixedly installed on the rotating end of the crankshaft 1. The crankshaft 1 rotates and drives the conjugate cam 2 to rotate. A conjugate cam roller 3 is rolledly connected to one side of the conjugate cam 2. The conjugate cam roller 3 is rotatably mounted on the roller seat 4. The conjugate cam 2 pushes the conjugate cam roller 3 and the roller seat 4 to swing through rotation. The roller seat 4 is connected to a rocker arm 7 through a connecting rod 5, which is used to drive the rocker arm 7 to swing together. This is the second swing. The rocker arm 7 is connected to the puller roller 6 through the puller roller hole seat and the drive shaft gear mechanism, thereby realizing the swing and rotation of the puller roller 6.
[0048] The differential gear system includes a front sun gear 14, which is connected to one end of the crankshaft 1 via a rocker arm 10, and is meshed with a planetary gear 11. The rotation of the crankshaft 1 drives the rocker arm 10 to push and pull the front sun gear 14 to swing within a certain range, which is the first swing. The differential gear system also includes a planetary carrier gear 12, which is driven by the uniform rotation of the rotating end of the crankshaft 1, which is a unidirectional rotational motion. The planetary gear 11 is rotatably mounted on the planetary carrier gear 12, and its teeth are located at both ends. The planetary gear 11 is meshed with a rear sun gear 15, and the rear sun gear 15 is coaxially connected to a double gear 16. The double gear 16, the rear sun gear 15, the front sun gear 14, the planetary carrier gear 12, and the rocker arm 10 are all rotatably connected to the cradle shaft 13.
[0049] The moving shaft gear mechanism includes a gear set 9, which includes an input gear a. The input gear a meshes with a double gear 16, and the input gear a is connected to an output gear b via gear transmission. The output gear b meshes with a pull-out roller drive gear c, which is fixedly connected to the pull-out roller 6. The input gear a, output gear b, and pull-out roller drive gear c are all rotatably connected to the moving shaft gear seat 8. The moving shaft gear seat 8 is fixedly mounted on a rocker arm 7 and swings with the rocker arm 7 to achieve the coordinated drive of the differential gear system and the yoke cam connecting rod combination to drive the movement of the pull-out roller 6, that is, to combine the first composite motion and the second swing.
[0050] Working principle: The crankshaft 1 rotates counterclockwise at a constant speed, which drives the conjugate cam 2 to push the conjugate cam roller 3 and roller seat 4 to swing together. In turn, the connecting rod 5 drives the rocker arm 7, the moving shaft gear seat 8 and the hole seat of the pull-out roller 6 to swing together, so that the pull-out roller 6 swings. This is the second swing made by the motion drive of the conjugate cam connecting rod combination mechanism.
[0051] Meanwhile, crankshaft 1 is connected to several fixed-axis gears (same as the original machine). Figure 1 (Not shown in the text) The meshing transmission drives the planetary carrier gear 12 of the differential gear system to rotate counterclockwise in one direction. The planetary carrier gear 12 and the front sun gear 14 drive the planetary gear 11 to revolve and rotate on its own axis. The planetary gear 11 drives the rear sun gear 15 to rotate. The rear sun gear 15 is fixedly connected to the double gear 16 and rotates together. The crankshaft 1 drives the rocker arm 10 and the front sun gear 14 fixedly connected to it to swing together, that is, the first swing, and then realizes the combination of the first swing and the unidirectional rotation into a single composite motion.
[0052] Then the moving shaft gear mechanism Figure 3The input gear a meshes with the double gear 16 of the differential gear system, and its output gear b meshes with the pull roller drive gear c fixed on the pull roller 6, so as to realize the oscillation of the cradle 7 and the motion synthesis of the double gear 16, thereby realizing the synthesis of the first synthesis motion and the second oscillation, and completing the two motion synthesis.
[0053] Therefore, this invention achieves a novel driving mechanism for the motion of the puller roller 6 by synthesizing the active motion input into two motions and then coordinating them to drive the puller roller 6.
