Abstract

The invention discloses a multifunctional machine head for a quilting machine. The machine head comprises a casing. A machine head upper shaft is arranged in the casing, one end of the machine head upper shaft is connected with a machine needle through a four-connection-rod mechanism to drive the machine needle to move vertically in a reciprocating mode, and the other end of the machine head upper shaft is connected with a synchronous motor through a coupler to drive the machine head upper shaft to rotate and provide power for movement of the machine needle. In the use process of the machine head, the synchronous motor rotates to drive the machine head upper shaft to rotate through adaptation connection of the coupler, and rotation of the machine head upper shaft is converted into vertical reciprocating movement of the machine needle through the four-connection-rod mechanism. The power for vertical reciprocating movement of the machine needle is provided in a mode that the synchronous motor and the machine head upper shaft are directly coupled, so that main moving speed of the machine head in the use process is increased, and vibration and noise are greatly reduced.

Description

technical field [0001] The invention relates to a machine head for a multifunctional quilting machine, in particular to a machine head for a multifunctional quilting machine which is powered by a synchronous motor to provide up and down reciprocating motion of needles. Background technique [0002] The power of the multifunctional quilting machine head used at present to drive the needle to reciprocate up and down is driven by a synchronous belt. In the process of specific use, the main movement speed of the machine head of the multi-functional quilting machine driven by the synchronous belt is not high, and at the same time, the vibration is severe, and it will emit a large noise. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a multifunctional quilting machine head for a multi-functional quilting machine in which a synchronous motor provides the power for the up and down reciprocatin...
