Sewing machine winder orienting mechanism

Abstract

The invention discloses a sewing machine winder orientation mechanism. The sewing machine winder orientation mechanism comprises a winding wheel body, a main shaft, a positioning ring and a positioning block, one end of the main shaft is fixedly connected with the winding wheel body through a pin, and the position, on the upper portion of the winding wheel body, of the outer wall of the main shaftis movably connected with the positioning ring in a sleeved mode. Through shifting of a pressing line control plate, when an auxiliary shaft begins to rotate, the positioning block and a guide blockrotate along with the auxiliary shaft, a positioning groove in the positioning ring is separated from a clamping hook of the positioning block, the auxiliary shaft rotates anticlockwise slightly to drive the guide block to rotate, and thus the contact between an elastic piece and the arc section of the guide block is changed into linear section contact; due to the elastic action of the elastic piece, the clamping hook of the positioning block is clamped in the positioning groove of the positioning ring, at the moment, the main shaft stops rotating, orientation is completed, positioning is accurate, and it is guaranteed that the positioning ring and the positioning block are connected smoothly in a clamped mode; and through fixed connection of the positioning block and the guide block, space is saved while connection is convenient, and it is guaranteed that the overall size of a winder is small.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine thread winder orientation mechanism. Background technique [0002] When the sewing machine is working, it is necessary to wind the thread on the bobbin and place it in the bobbin case to ensure the completion of the target requirements. In order to improve the winding efficiency, a winding device is added on the upper part of the machine, which can realize the function of winding while working. The thread winder on the current sewing machine is the whole assembly, and the mounting plate of the thread winder is fixed on the machine head with screws to realize the fixing of the thread winder. When the installed thread winder is working on the sewing machine, it will automatically drive the rotating shaft on the thread winder to rotate, and finally realize the function of automatic thread winding. After each winding, the wire winder uses the orientation me...

Problems solved by technology

[0003] 1. When the orientation mechanism of the sewing machine winder in the prior art is in use, when the locking device is not snapped into the corresponding slot, the locking device will rub against the surface of the component with the slot, causing the main shaft of the winder to stop, resulting in uncertainty in the position of the cutting knife, which is not conducive to the user to cut the suture on the bobbin after the winding is completed. Only when the position is adjusted can the cutting work be carried out, which increases the workload of the user and wastes time

[0004] 2. In the prior art, when the directional mechanism of the sewing machine winder is in use, the overall structure is complex, the manufacturing cost is high, and the size of the directional mechanism is large, resulting in a large overall size of the thread winder and occupying space
