Description
Technical field
The utility model relates to a kind of sewing machine, relates in particular to a kind of hook line mechanism of shoes mending machine.
Background technology
China has been world Sewing machines big producing country, and production concentration degree obviously improves, and the regional structure that is representative with six major production areas such as Shanghai, Zhejiang, Shaanxi, Tianjin, Jiangsu, Guangdong is tending towards reasonable.Professional division and co-operative system form between complete machine, parts manufacturing enterprise, and socialization production degree improves constantly.The product class is complete basically, and is wide in variety, and the existing product of throughout the year producing tens of kinds before 20 years is increased to present kind more than 1000.Product quality level improves constantly, and conventional products such as high speed parallel sewing machine, high speed overlock industrial sewing machine have reached or approached advanced international standards, and the industry research and development strength goes from strength to strength, and technology improves constantly with equipment.The sewing function is made goods such as fabric such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, the stitching neat appearance of stitching out, smooth firm, and sewing velocity is fast, easy to use.The stitching of Sewing machines can reduce two types of lock-type chain stitch and chain-type stitchs.Lock-type chain stitch is the most common, and it is made up of two sutures, as making a rope by twisting the strands together, is interweaved, and its intertwined point is in the middle of sewing.See that from the cross section of stitching two sutures lock as two locks mutually, thereby are called lock-type chain stitch.This stitching is used in sewings such as the little cotton of shrinkage factor, wool fabric or leather, and the obverse and reverse shape is identical, like same dotted line.Stitching distributes closely knit, and the fastness of sewing generally surpasses handspin.Chain-type stitch is to be formed from connecting or interconnect by the wire loop of suture, and that uses always has single line chain type, two-wire chain type and a three yarn closed seam stitching.The characteristics of this stitching are the stitching high resiliences, can be with the flexible and sutures that can not break of sewing, be applicable to goods that clothes or the overseam of line system elastic fabric is easy loose and clothing base etc.General Sewing machines all is made up of head, support, transmission and annex four parts.Head is the major part of Sewing machines.It is made up of thorn material, hook line, take-up, four mechanisms of feeding and auxiliary bodies such as coiling, binder, the tooth that falls, and each motion of mechanism reasonably cooperates, and periodic duty unites by a seam sewing.The running part of Sewing machines is made up of parts such as frame, hand-operated device or motor.Frame is the pillar of machine, is supporting platen and pedal.The operator steps on pedal during use, through the rotation of crank drive belt pulley, drives the head rotation through belt again.Hand-operated device or motor majority directly are contained on the head.
The hook line transmission mechanism of Sewing machines adopts twopiece drive shaft mostly, cooperates double cam to drive the course of work that rotating shuttle is realized the hook line, its complex structure, and inconvenient maintenance, and noise is bigger.
The utility model content
For addressing the above problem, the utility model provides a kind of hook line mechanism of shoes mending machine.
The utility model adopts following technical scheme,
A kind of hook line mechanism of shoes mending machine includes transmission device, and transmission device is connected with rotating shuttle; Rotating shuttle is located in the workbench of shoes mending machine; Corresponding with the eedle position, said rotating shuttle bottom is connected with swing arm, and the bottom of this swing arm has gear; With the terminal gears engaged of transmission device, transmission device drives swing arm and rotating shuttle rotates;
Said transmission device includes driving shaft, and driving shaft rotates through the gear driven vertical pivot, and vertical pivot is terminal to be connected with lower shaft through gear, and following shaft end is connected with said swing arm through gear;
Said workbench end has containing cavity, and said rotating shuttle is arranged in this containing cavity;
Said vertical pivot is vertical with lower shaft with driving shaft respectively, and said lower shaft is vertical with said swing arm.
The advantage of the utility model is, because this hook line mechanism has adopted the crossed helical gears transmission device, transmission is accurate, steady, and mechanical efficiency is high, long service life, and be convenient to maintenance, operating noise is little.
Description of drawings
Fig. 1 is the explosive view of the hook line mechanism of the utility model proposition.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, the hook line mechanism of the shoes mending machine that the utility model proposes includes transmission device, and transmission device is connected with rotating shuttle; Rotating shuttle 210 is located in the workbench 200 of shoes mending machine; Corresponding with the eedle position, said rotating shuttle 210 bottoms are connected with swing arm 220, and the bottom of swing arm 220 has gear 221; With the terminal gears engaged of transmission device, transmission device drives swing arm 220 and rotating shuttle 210 rotates;
Particularly, said transmission device includes driving shaft 110, and driving shaft 110 middle parts have gear 111; Vertical pivot 120 upper ends have gear 121, and driving shaft 110 rotates through gear driven vertical pivot 120, and vertical pivot 120 ends have gear 122; Gear 131 through being installed on the lower shaft 130 drives lower shaft 130 rotations; Lower shaft 130 is connected with swing arm 220 through gear 132, and vertical pivot is vertical with lower shaft with driving shaft respectively, and said lower shaft is vertical with said swing arm; In addition, said workbench 200 ends have containing cavity 201, and rotating shuttle 210 is arranged in containing cavity 201, by cover plate 202 rotating shuttle 210 is sealed.
This hook line mechanism is owing to adopted the crossed helical gears transmission device, and transmission is accurate, steady, and mechanical efficiency is high, long service life, and be convenient to maintenance, operating noise is little.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
