Through the analysis of the working principle of the tufting machine, it can be seen that the key technology in the control system of the tufting machine is the process of yarn conveying and the process of cutting piles formed by the action of the cutter. In the design of the system, the control of the whole system is realized through the control of these two aspects.
The drum and the pressing wheel squeeze the yarn, so that the yarn is fed down with the drum at a certain speed. Different rollers produce different speeds, forming fluff with different heights.
As long as the actions of two different sets of solenoid valves are controlled, and the gas delivery is determined by the actions of the solenoid valves, the actions of two sets of different pressure rollers can be controlled. Two sets of control circuits are required here, and the control principles are exactly the same, the only difference is the rotation speed of the drum.
The drum generates a certain speed through the linkage between the cam and the gear of the mechanical structure. In addition, in the combined system of the spring piece, the hooking assist piece and the cylinder, it is necessary to increase the control of the spring piece, and through the control of the position of the spring piece, the loop pile or cut pile carpet pattern can be obtained.
