Abstract

The utility model aims to provide a transmission mechanism of the dial linking machine with simple structure, few moving orbits, reliable transmission, little noise, which adopts the following technological programs: the machine comprises a synchronous gear, a connecting pole, a taking-up plate whose end portion can take-up thread and is arranged on the connecting pole that is driven by the synchronous gear. The utility model makes the sutures form stable loops during the process of the needle moving back and the moment that the take-up plate clamps the thread. The structure of the utility model is simple, which avoids damage and noise caused by direct friction of the two-set cam wheels driving the connecting pole drive and makes the procedures of transmission and taking-up threads much more reliable.

Description

The sewing machine winding mechanism

Technical field

The utility model is sewed up the winding mechanism of sewing machine of garment piece, neckline, cuff, the shoulder of all kinds of sheep lines, knitting wool, acrylic varicosity line and the braiding of various blended yarn about a kind of technical field of knitting machinery.

Background technology

Sewing machine is one of weight equipment of woolens industry, is used for sewing up operations such as garment piece, collar, clothing pin, cuff, shoulder with sweater factory, knitwear factory, and be the indispensable equipment of sweater producer.The winding mechanism of existing sewing machine generally all is that suture is passed sewing needle, when serving textile, owing between fabric and the suture friction is arranged, by forming coil when the withdraw of the needle, hooked for next pin by catch and insert, the coiling program of this structure is to drive moving of catch by two cover cam driven connecting rods, and the coiling stroke of catch is the 8 fonts motion of both direction, weekly more than phase walking eight step, the line of catch stroke counts that track is many, its drives structure complexity, move loaded down with trivial details.This transmission mechanism quick abrasion, and the mechanism that realizes these motions drives catch by eccentric wheel or cam driven connecting rod to move and finish, and noise is big during operation.Because the drives structure complexity, need to refuel before using every day and sewing machine was rotated several minutes, wipe greasy dirt with cloth again, but greasy dirt is difficult to wipe clean, the clothes of former stitchings is easily made dirty, and maintenance, safeguards and take length, uses comparatively inconvenience.

Summary of the invention

The utility model be intended to provide a kind of simple in structure, running orbit is few, the winding mechanism of reliable transmission, sewing machine that noise is little.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of sewing machine winding mechanism includes synchromesh gear, connecting rod, but the connecting rod that synchromesh gear drives is provided with the take-up board of end take-up.

Compared with prior art, beneficial effect described in the utility model is to drive moving of take-up board by the synchromesh gear drivening rod, drive the sewing machine drive mechanism (number of patent application: 03225632.9) of the device of this winding mechanism referring to the inventor, time delay swing by take-up board, thereby make suture in the process of the suture needle withdraw of the needle, the moment of take-up integrated circuit board line, form stable wire loop, make take-up board can block line accurately, prevented the generation of loose ends ring, sew up various wool yarn wire fabrics and all obtain promising result, improved the adaptive capacity and the quality of sewing machine greatly.The utility model is simple in structure, and abrasion and the noise of having avoided the direct frictions of two cover cam driven connecting rod transmissions to produce make transmission, take-up program more reliable.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

Driven wheel 7 is connected with synchromesh gear 5 by belt 6, and the device of this driven wheel 7 of transmission is referring to inventor's sewing machine drive mechanism (number of patent application: 03225632.9), make synchromesh gear 5 obtain the arc rotation of time delay.But the connecting rod 4 that synchromesh gear 5 drives is provided with the take-up board 1 of end take-up, and take-up board 1 is connected on the connecting rod 4 by pedestal 2, or take-up board 1 also can directly be connected on the connecting rod 4.Connecting rod 4 is provided with guard housing 3, can not swing in high speed rotating with stationary links 4.The end of take-up board 1 for can choose (card) but line opening or be the take-up hook, take-up board 1 the place ahead is provided with the catch 8 that can keep off line.In the process of sewing needle 9 withdraws of the needle, connecting rod 4 drives pedestal 2 and drives take-up board 1 rotation, take-up board 1 blocks suture, shown in Fig. 3 (schematic diagram of the utility model embodiment withdraw of the needle state), take-up board 1 blocks suture and is rotated further certain angle at this moment, makes catch 8, take-up board 1, sewing needle 9 form stable wire loop, shown in Fig. 4 (schematic diagram of the utility model embodiment inserting needle state), sewing needle 9 inserting needles pass this coil, and take-up board 1 revolution that resets this moment forms a stable line and saves.The serving textile of so periodically working.

Above illustrated embodiment is only with for conveniently illustrating the utility model, and at technical scheme category described in the utility model, the person of ordinary skill in the field does various simple deformation and modification, all must be included in the above claim.
