Embodiment Construction

[0023] The auxiliary cloth mopping mechanism of the sewing machine of the present invention includes a swing mechanism composed of a swing shaft 22 installed on the base frame 40 and swing assemblies at both ends thereof, a one-way rotation mechanism composed of a lower cloth wheel and a rotating locking assembly in its abdominal cavity, The adjustment mechanism of the lower cloth wheel mainly composed of the pressure rod, its guide block and the large spring. The swing mechanism is connected with the one-way rotation mechanism through the cloth wheel connecting rod 48, and the one-way rotation mechanism is passed through the long support of the cloth wheel. 27 is connected with lower cloth wheel adjusting mechanism. The following are their specific structures.

[0024] 1. The connection relationship between the swing shaft and its two ends (swing mechanism).

[0025] As shown in FIGS. 1 and 2 , the swing shaft bearings 23 installed on the swing shaft 22 are fixed in the hole...

Abstract

The auxiliary cloth dragging mechanism for sewing machine has simple structure and raised sewing quality. Structurally, the auxiliary cloth dragging mechanism features that the main driving shaft transmits the driving force to the link rod and the connected rotary locking part of the cloth pressing wheel via the shaft in the frame and the swinging assembly so as to make the link rod and the rotary locking part reciprocate and the cloth pressing wheel rotate intermittently in one direction. The cloth pressing wheel is connected to the pressing rod in the wheel lifting and pressure regulating mechanism. The cloth pressing wheel may be lifted as required and the pressure of the cloth pressing wheel may be regulated based required cloth feeding speed. The present invention is suitable for sewing machine for thick or even very thick cloth.

Description

Technical field [0001] The invention relates to a sewing machine, in particular to a mechanism used in the sewing machine capable of moving thick cloth. Background technique [0002] The auxiliary mop mechanism of the sewing machine of Juki, its swing shaft is connected to a rotating link, and then connected to a fork crank. A special bearing that can rotate in one direction is installed in the inner hole of the fork crank. A synchronous pulley is driven by the fork crank to achieve the purpose of one-way mopping. However, the sewing machine auxiliary mop mechanism of Nippon Juki has a complex overall structure, high technical requirements for the manufacture and installation of the one-way rotating bearing, and the price of the whole machine is expensive, which is not conducive to popularization and use. [0003] Though the sewing machine of my country Taiwan has auxiliary mop mechanism, its basic structure is not obvious with structure comparability of the present invent...
