Description

Technical Field

[0001] The present invention relates to the technical field of sewing machines, and particularly to a thread bobbin rotating and winding device. Background Art

[0002] Industrial sewing machines are designed for mass-producing sewn workpieces in factories and other industrial fields. A rotary hook in an industrial sewing machine is equipped with a thread bobbin, which includes a bobbin case and a bobbin core, and the bobbin core is wound with sewing thread. Since the sewing thread accommodation capacity of the bobbin core is limited, sewing must be stopped to replace the bobbin core wound with sewing thread after the sewing thread in the bobbin core is exhausted. The current automatic winding machine first presses the thread end on the end face of the bobbin core, and then the bobbin core slowly rotates to wind 5 to 6 turns of sewing thread to ensure that the sewing thread is wound as the bobbin core rotates. However, there is a thread end left after winding by the existing automatic winding machine, and it cannot automatically lead the thread end into the thread passing hole of the bobbin case. The driving structure for automatic winding only needs to achieve rotational motion, but it is difficult to lead the thread end, and various complex actions of manual thread leading need to be simulated. Therefore, in order to achieve automatic winding and thread end leading, multiple driving structures are required for driving. However, the increase in driving structures will make the structure complex and occupy a large volume, and there are high requirements for the layout of space and position.

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] The device of the present application is used in cooperation with a bobbin. First, the corresponding two types of bobbin structures will be introduced below. Referring to Figure 1-4 As shown, the first type of bobbin 7 includes a bobbin case 71 and a bobbin core 72.

The hook-shaped tip of the bobbin leather 714 corresponds to the thread passing hole 715 and divides the thread passing hole 715 into a first partition 715a and a second partition 715b. The bobbin core shaft 719 can be inserted into the winding shaft 722 of the bobbin core 72, and a core hole 7191 is provided in the middle of the bobbin core shaft 719.

After the bobbin door cover plate 712 is laid flat, the bobbin door bottom plate 713 can pop out to hold the core shaft groove of the positioning core shaft in the rotary hook.

[0039] Referring to Figure 5-7 As shown, the difference between the second type of bobbin 7 and the first type of bobbin 7 is that the bobbin case 71 of the second type of bobbin 7 further includes a thread passing spring 720 installed on the bobbin shell 711.

[0041] A thread - winding device for a bobbin rotationally winds threads, in combination with Figure 8 - Figure 15 As shown, it includes: a bobbin driving component for driving the bobbin 7 to rotate and slide along the rotation axis, and a thread - winding knife driving component for driving the thread - winding knife 121 to rotate around the bobbin 7;

[0042] The bobbin driving component includes: a thread - winding station disk 111 for cooperating with the bobbin core 72, a thread - winding main shaft 112 having a first installation cavity opened at one end facing the bobbin 7, a sliding component coaxially fixed to the thread - winding main shaft 112, a reset elastic member 115 installed in the first installation cavity, and a thread - winding main - shaft driver 116 for driving the thread - winding main shaft 112 to rotate; the sliding component includes a thread - winding core shaft 114 and a thread - winding sleeve 113, the thread - winding core shaft 114 and the thread - winding sleeve 113 are coaxially arranged and connected by a profile connection, one end of the thread - winding core shaft 114 penetrates into the first installation cavity and then connects to the reset elastic member 115, and the other end passes through the thread - winding sleeve 113 and is coaxially fixedly connected to the thread - winding station disk 111, and the reset elastic member 115 has a tendency to hinder the thread - winding core shaft 114 from sliding along the rotation axis;

[0043] The thread - winding knife driving component includes a thread - winding sleeve 128 coaxially arranged with the thread - winding core shaft 114 and a thread - winding - knife rotation driver 122 for driving the thread - winding sleeve 128 to rotate, and the thread - winding sleeve 128 drives the thread - winding knife 121 to rotate.

[0044] In this application, by setting the thread - winding main - shaft driver 116 to drive the thread - winding main shaft 112 to rotate, and then driving the sliding component to rotate synchronously; and by coaxially connecting the thread - winding sleeve 113 with the thread - winding main shaft 112, connecting the thread - winding core shaft 114 and the thread - winding sleeve 113 by a profile connection, and using the reset elastic member 115 for the reset of the thread - winding core shaft 114; and then connecting the thread - winding station disk 111 with the thread - winding core shaft 114 to cooperate with the bobbin 7 and support the bobbin 7, it can not only meet the high - speed rotation of the bobbin core 72 for winding threads, but also ensure that the thread - winding station disk 111 and the bobbin 7 can float along the rotation axis, so that the bobbin 7 can move along with the movement of the robotic arm of the automatic thread - winding machine in the direction of the rotation axis. Also, by driving the thread - winding sleeve 128 to rotate through the thread - winding - knife rotation driver 122, the thread - winding sleeve 128 drives the thread - winding knife 121 to rotate around the bobbin 7.

A fourth step surface 1125 is formed at the connection between the first cylindrical section 1122 and the second cylindrical section 1123. During assembly, the winding spindle 112 is inserted into the first circular hole 1171 of the second installation cavity. The first cylindrical section 1122 enters and passes through the fourth circular hole 1174. The third cylindrical section 1124 can abut against the second step surface 1176 to prevent the winding spindle 112 from falling, and it is convenient to install the winding spindle bearing 1287 from the opposite direction. The first winding spindle bearing 1287 is sleeved on the first cylindrical section 1122 from the side of the connecting shaft section 1121 of the winding spindle 112, so that its inner ring abuts against the fourth step surface 1125 and the outer ring abuts against the third step surface 1177 to achieve positioning. A spacer sleeve 1126 is sleeved on the first cylindrical section 1122, and the spacer sleeve 1126 abuts against the inner ring of the first winding spindle bearing 1287.
