Embodiment 1

[0031] Such as Figure 1-7 As shown, the sewing machine winder includes a machine base 1, on which a bobbin installation shaft 2 and a counting rotating body 3 are rotatably connected. 3 is provided with a signal acquisition mechanism 5 capable of collecting and counting the number of rotation signals of the rotating body 3, the signal acquisition mechanism 5 and the rotation drive mechanism 4 are connected to the signal processing circuit 6 respectively, and the signal processing circuit 6 is connected with a cable length prompt module 7 And control module 8, adopt counting rotating body 3 to rotate number of laps and record length can get rid of the influence that directly measures bobbin rotation cycle counting precision insufficient, reason is that counting rotating body 3 is not subject to wire rod winding more, and the wire of every rotation The longer the impact, the counting rotating body 3 rotates a constant length across the line, so the length measurement is more ac...

Embodiment 2

[0040] Such as Figure 8 As shown, the working principle of this embodiment is basically the same as that of Embodiment 1, the difference is that the signal acquisition mechanism 5 here includes at least one photoelectric sensor 11 connected to the signal processing circuit 6 and at least one sensor installed on the counting rotating body 3 The light blocking body 12, the photoelectric sensor 11 is arranged on the base 1, the photoelectric sensor 11 has a notch 13 with a size larger than the light blocking body 12, and a transmitter and a receiver are respectively arranged on both sides of the notch 13, and the light blocking body The number of 12 is multiple, and each light-blocking body 12 is evenly distributed on the same circle with the rotation center of the counting rotating body 3 as the center, and is calculated by the number of times that the light-blocking body 12 passes between the transmitter and the receiver in the slot 13 The number of turns of the rotating body ...

Abstract

The invention provides a bobbin winder of a sewing machine which solves the conventional technical problems. The bobbin winder of the sewing machine comprises a base, wherein a bobbin mounting shaft and a counting rotary body are rotationally connected onto the base; the bobbin mounting shaft is connected with a rotation driving mechanism; a signal acquisition mechanism capable of collecting signals of the rotating lap number of the counting rotary body is arranged between the base and the counting rotary body; the signal acquisition mechanism and the rotation driving mechanism are connected with a signal processing circuit; a thread length prompting module and a control module are connected onto the signal processing circuit. The bobbin winder of the sewing machine has the advantages of high winding precision, small error and the like.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a thread winder for sewing machines. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. A bobbin is a component in a sewing machine that holds the sewing thread wound around the body of the bobbin. When the bobbin is in use, the sewing thread is passed out step by step through its own rotation, and there is no phenomenon that the sewing thread itself is entangled and knotted. At present, the amount of thread used by sewing machines is relatively large, and the demand for bobbin winding is also increased, so a kind of bobbin winder is needed to reduce the waste of labor. [0003] The thread winder currently on the market generally includes a thread gripper and a bobbin arranged on the box body. The wire is wound on ...
