Problems solved by technology

However, sewing machines usually work non-intermittently, and the amount of thread on the bobbin is limited, so in order to meet the needs of continuous operation of the sewing machine, the bobbin in the rotary hook device needs to be constantly replaced during the working process of the sewing machine.
[0004] During the shuttle changing process, the replaced bobbin needs to be wound with a new bottom thread. At this time, it is necessary to manually complete the threading and winding of the bobbin, which is inefficient

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 with 2 As shown, a bobbin automatic winding device includes a winding module 1, and the winding module 1 includes a winding shaft 11 coaxially arranged from the inside to the outside and capable of synchronous rotation, a picker 12 and a holder 13, The bobbin shaft 11 is used to install the bobbin case 72 and to drive the bobbin case 72 to rotate together; the holder 13 is used to hold the bottom thread 8 that passes through from the front; The winding shaft 11 moves to grab the bobbin 71 to take the bobbin 71 out of the bobbin case 72 to the front of the holder 13 , and then drives the bobbin 71 to rotate for winding.

[0028] The bobbin automatic winding device can automatically take out the bobbin 71 from the bobbin case 72 through the mutual cooperation of the bobbin winding shaft 11, the shuttle remover 12 and the grippe...

Abstract

The invention discloses an automatic bobbin winding device. The automatic bobbin winding device comprises a winding module; the winding module comprises a winding shaft, a bobbin taking device and a clamping device, and the winding shaft, the bobbin taking device and the clamping device are coaxially arranged from inside to outside and can rotate synchronously, and the winding shaft is used for installing a bobbin case and driving the bobbin case to rotate together; the clamping device is used for clamping a bottom thread penetrating from the front of the clamping device; and the bobbin taking device can move along the winding shaft and is used for grabbing the bobbin so as to take the bobbin out of the bobbin case to the position in front of the clamping device, and then driving the bobbin to rotate for winding. The automatic bobbin winding device can complete bobbin winding in a full-automatic mode.

Description

technical field [0001] The invention relates to the shuttle changing technology of a sewing machine, in particular to an automatic bobbin winding device. Background technique [0002] A sewing machine is a machine that uses one or more bottom threads to form one or more stitches on the fabric to interweave or sew one or more layers of fabric. [0003] The existing sewing machine needle plate is generally provided with a rotary hook device below the needle plate, and a bobbin is arranged in the rotary hook device, and the bobbin is wound with a bottom thread, so as to cooperate with the upper thread on the machine head machine needle to complete the stitching of the fabric. But sewing machine usually all works non-intermittently, and the amount of thread on the bobbin is limited, so in order to meet the requirement of continuous operation of sewing machine, need constantly change the bobbin in the rotary hook device in the process of sewing machine work. [0004] During the ...
