Abstract

The invention discloses a multi-head embroidery machine and a double-drive-shaft clutch mechanism thereof, which belong to the technical field of embroidery, wherein an axial clutch piece moves along the axial direction in the clutch process so as to realize transmission separation from one of a first drive shaft and a second drive shaft and transmission connection with the other, and a drive shaft positioning structure is used for realizing circumferential positioning of the first drive shaft and the second drive shaft which are subjected to transmission separation from the axial clutch piece so as to limit the rotation of the first drive shaft or the second drive shaft. Therefore, one of the first driving shaft and the second driving shaft which are separated from the axial clutch piece can be circumferentially positioned so as to ensure that the convex teeth and the tooth grooves between the axial clutch piece and the first driving shaft and the second driving shaft are re-meshed when the axial clutch piece is next clutched.

Description

Multi-head embroidery machine and double-driving-shaft clutch mechanism thereof Technical Field The invention belongs to the technical field of embroidery equipment, and particularly relates to an embroidery machine. Background The coil embroidery machine in the prior art comprises a transversely extending mounting beam and a plurality of coil embroidery machine heads mounted on the mounting beam, and in order to realize flat embroidery, flat embroidery machine heads can be arranged among the plurality of coil embroidery machine heads at intervals. Wherein the tape embroidery heads are driven by a first spindle and the flat embroidery heads are driven by a second spindle, the first spindle extending transversely and passing through the plurality of tape embroidery heads, the second spindle extending transversely and passing through the plurality of flat embroidery heads. In addition, in order to reduce the number of motors by driving the first spindle to rotate by the first drive shaft and driving the second spindle to rotate by the second drive shaft, respectively, the applicant has developed a single motor driving structure in which the first drive shaft and the second drive shaft are driven by one motor, and only one of the first drive shaft and the second drive shaft is operated at the same time. Therefore, a double-drive shaft clutch mechanism is provided, wherein the axial clutch member is used for realizing transmission separation or transmission connection with the first drive shaft and the second drive shaft, as the axial clutch member is connected with the first drive shaft and the second drive shaft through the engagement of the convex teeth with the tooth grooves of a circumferential set angle, after the axial clutch member is separated from one of the first drive shaft and the second drive shaft in a transmission manner, if the first drive shaft and the second drive shaft continue to rotate, the convex teeth between the axial clutch member and the first drive shaft and the second drive shaft are difficult to ensure to be engaged again with the tooth grooves in the next clutch. Disclosure of Invention The technical problem to be solved by the invention is to provide a multi-head embroidery machine and a double-drive shaft clutch mechanism thereof, which can circumferentially position one of a first drive shaft and a second drive shaft which are separated from an axial clutch piece so as to ensure that convex teeth and tooth grooves between the axial clutch piece and the first drive shaft and the second drive shaft are re-meshed in the next clutch.
