Description

Technical Field

[0001] The utility model relates to a yarn transmission mechanism for a textile machine, in particular to a yarn transmission mechanism for a textile machine whose belt pulley can be more easily replaced. Background Art

[0002] According to the existing textile machine yarn transmission mechanism, there are many Figure 8 and Fig. 9 As shown, the transmission mechanism (30) mainly comprises a bracket (31), the outer periphery of the bracket (31) is provided with a convex portion (311), and the transmission mechanism (30) is installed on the textile machine by the convex portion (311). The bracket (31) is formed with a through hole-shaped receiving groove (312), and the bearing (32) is provided by the receiving groove (312) to be placed in the sleeve, and then the spindle (33) inserted in the bearing hole (321) of the bearing (32) is extended to one end of the bracket (31), so that a pulley (33) can be pivotally provided outside one end of the bracket (31) through the spindle (33). 34), when a transmission mechanism (30) is installed on each side of the textile machine, and the belt on the servo motor is passed around the pulleys (34) of the two transmission mechanisms (30), the servo motor can be used to drive the belt to rotate forward and reverse, so that a yarn feeding device connected to the belt can make accurate reciprocating translation between the two transmission mechanisms (30), and the groove (313) (331) is provided on the receiving groove (312) and the spindle (33), and the C-shaped buckle (35) is used to buckle the groove (313) (331) to limit the set of the bearing (32).

[0003] However, the above-mentioned existing structure still has the following problems in practical application: (i) the pulley (34) will rotate at a high speed after being driven, and in this state, the pulley (34) will be easily damaged. However, because the pulley (34) is connected to the bearing (32) through the spindle (33), and the bearing (32) is completely hidden in the groove (312) of the bracket (31), when the pulley (34) is damaged and needs to be replaced together with the bearing (32), it is necessary to remove the entire transmission mechanism (30) from the textile machine, and then use a tool to force the bearing (32) out of the groove (312). The groove (312) can only be replaced smoothly with such cumbersome steps, which will cause the pulley (34) to be difficult to replace, and will seriously delay the working time under the long-term shutdown replacement; (ii) there will be more or less clearance between the pulley (34) and the spindle (33), between the spindle (33) and the bearing (32), and between the bearing (32) and the groove (312), so that the pulley (34) cannot be completely concentric with the groove (312). As a result, a large shake will occur during the rotation process of the pulley (34), making the pulley (34) more likely to be damaged.

[0004] Therefore, how to develop and improve the shortcomings of the above-mentioned existing textile machine yarn transmission mechanism is indeed a goal that the relevant industry needs to work hard on. In view of this, the inventor of the present utility model thought about the idea of ​​creation, and then designed it with many years of experience. After many discussions and sample tests, and many revisions and improvements, the present utility model was launched. Utility Model Content
