Problems solved by technology

[0004] However, the above-mentioned existing sewing machine obtains power from the cloth feeding motor to reciprocate the feed teeth in the horizontal direction, but the stroke of the reciprocating motion in the horizontal direction of the feed teeth is greater than the reciprocating motion in the up-down direction of the feed teeth. The problem that the load on the cloth feeding motor becomes larger
[0005] In addition, the reciprocating motion of the feed teeth in the horizontal direction is accompanied by the motion of conveying the sewing object, so the load on the material feeding motor becomes large, which also hinders the increase in speed.

Embodiment Construction

[0123] [Schematic structure of the embodiment]

[0124] Next, a sewing machine as an embodiment of the present invention will be described in detail.

[0125] figure 1 It is a perspective view which shows the main structure inside the sewing machine base part of the sewing machine 100. FIG.

[0126] Such as figure 1 As shown, the sewing machine 100 is provided with: an unillustrated sewing needle up and down movement mechanism, which moves the sewing needle up and down; a sewing machine motor 16, which becomes a driving source of the sewing needle up and down movement mechanism (refer to Figure 7 ); the unillustrated upper shaft, which rotates through the sewing machine motor 16; the kettle 12, which winds the upper thread and the lower thread; The clothing material of the sewn object is conveyed; the transmission belt mechanism 20 transmits the rotational force from the upper shaft 33 of the feed device 30; the thread cutting device 14 cuts off the upper thread and the lo...

Abstract

The presser lifting mechanism of a sewing machine includes a cloth presser, a pressing rod which holds the cloth presser by a bottom end portion thereof, a rod holder which is fixed to the pressing rod, a pressing spring a bottom end portion of which is in contact with a top end portion of the rod holder and which pushes the cloth presser downward via the rod holder, a push-up member through which the pressing rod is inserted so as to be movable in the vertical direction and which is in contact with the rod holder from below and can pushed it up, a link body which is in contact with a bottom surface of the rod holder and is connected to the push-up member, and a presser motor which is linked to the link body and serves as a drive source for elevation and lowering of the cloth presser.

Description

technical field [0001] The invention relates to a sewing machine with feed adjustment. Background technique [0002] A sewing machine is proposed, which includes, in order to freely perform the movement of the feed teeth: a horizontal feed mechanism that receives power from a cloth feed motor to reciprocate the feed teeth in the horizontal direction with respect to the feed teeth; A feed mechanism that receives power from a sewing machine motor to reciprocate the feed teeth in the up and down direction for the feed teeth. The sewing machine combines the horizontal reciprocating motion and the up and down reciprocating motion and transmits them to support the feed teeth. The feed table of the machine is used to feed the cloth (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2013-22345 [0004] However, the above-mentioned existing sewing machine obtains power from the cloth feeding motor to reciprocate the fee...
