Description
Affiliated technical field
The present invention relates to the industrial sewing machine technical field, specifically a kind ofly be installed in sheet fabric haulage gear on the sewing machine table plate and that work asynchronously with Sewing machines.
Background technology
The kind of industrial sewing machine is a lot, and they all have different sewing effects.At present, the industrial sewing machine of the most frequently used sewing flat fabric sheet is when making such as fabrics such as building safety purse seine, Polywoven Bag and paulins, because these industrial sewing machines do not have corresponding fabric haulage gear, therefore when the sewing above-mentioned fabrics, generally all need two people's compounding practices.A people operates machines and feeding, and another person is the tractive fabric in the back, to guarantee to make as requested fabric.This industrial sewing machine because not corresponding traction feed mechanism, so when making fabric not only time-consuming taking a lot of work, the sewing difficult quality ensures, and inefficiency, the production cost height.
Summary of the invention
In order to overcome the deficiency that above-mentioned industrial sewing machine structurally exists, a kind of fabric synchronizing tractor of industrial sewing machine that the invention provides a kind of simple in structure, easy to operate, high efficiency, can effectively reduce production costs.
The technical solution adopted for the present invention to solve the technical problems is: this fabric synchronizing tractor of industrial sewing machine, comprise the support that is installed on the workbench and the driving wheel on the head, the rear side that mainly is said driving wheel is provided with the driven pulley of a belt driving gear by frame and bearing, is connected by belt between driving wheel and the driven pulley; Be provided with a rotating shaft and be fixed with differential gear by support and duplex bearing in a side of travelling gear at an end of rotating shaft, the other end is provided with initiatively transfer roller, be provided with the tooth sector that plays a supporting role between travelling gear and differential gear, travelling gear, tooth sector and differential gear intermesh; On the housing of duplex bearing, be provided with support bar, the top of support bar flexibly connects a connecting rod, one end of connecting rod and clutch for clutch control bar flexibly connect, and the other end connects the friction transfer roller by bearing pin, also are provided with to make friction transfer roller and the initiatively close-fitting extension spring of transfer roller between duplex bearing and connecting rod; Be equipped with on said active transfer roller and the friction transfer roller and can increase the friction of frictional force line.
The present invention's advantage compared with prior art mainly is novel structure, and is reasonable in design, and the synchronous effect of traction is good.Owing to utilize the motor of Sewing machines and the driving wheel on the head to be used as power, and under the effect of travelling gear, tooth sector and differential gear, make initiatively transfer roller, friction transfer roller and the run-in synchronism of sewing mechanism, solved the sync pulling problem of fabric in the sewing process better.Particularly under the acting in conjunction of connecting rod, clutch for clutch control bar and extension spring, make the active transfer roller can revise and keep the sewing direction of fabric at any time freely, improved the sewing speed of fabric greatly with the clutch of friction transfer roller is convenient.
Secondly, can increase work efficiency effectively, change the two people operation in past into one man operation, not only improve the sewing quality of fabric, and reduced production cost.Therefore, this fabric synchronizing tractor is installed and used on the passable industrial sewing machine of making sheet fabric widely.

The specific embodiment
As shown in Figure 1, 2, this fabric synchronizing tractor of industrial sewing machine is installed on the workbench of head of sewing machine rear side, utilizes the motor of Sewing machines to be power, the sewing mechanism run-in synchronism of it and Sewing machines.It comprises the support 9 that is installed on the workbench 8 and 11 and head on driving wheel 20, the rear side that mainly is said driving wheel 20 is provided with the driven pulley 13 of a belt driving gear 10 by frame 11 and bearing 12, is connected by belt 19 between driving wheel 20 and the driven pulley 13; Side at travelling gear 10 is provided with a rotating shaft 6 by support 9 and duplex bearing 7, and be fixed with differential gear 16 at an end of rotating shaft 6, the other end is provided with initiatively transfer roller 5, between travelling gear 10 and differential gear 16, be provided with a tooth sector that plays a supporting role 15, intermesh between travelling gear 10, tooth sector 15 and the differential gear 16; On the housing of duplex bearing 7, be provided with support bar 18, the top of support bar 18 flexibly connects a connecting rod 17, one end of connecting rod 17 and clutch for clutch control bar 14 flexibly connect, the other end connects friction transfer roller 2 by bearing pin 3, also is provided with to make friction transfer roller 2 and initiatively transfer roller 5 close-fitting extension springs 1 between duplex bearing 7 and connecting rod 17.On active transfer roller 5 and friction transfer roller 2, be equipped with and increase the friction of frictional force line 4.
The course of work of the present invention is: at first, be used as power by the motor of Sewing machines and the driving wheel 20 that is arranged on the head, driving wheel 20 drives driven pulley 13 runnings by belt 19, travelling gear 10 on the driven pulley 13 drives tooth sector 15 runnings, and tooth sector 15 drives differential gear 16 runnings again and the speed adjustment of finishing reaches run-in synchronism.Differential gear 16 drives initiatively by rotating shaft 6, and transfer roller 5 carries out antiport with friction transfer roller 2.When needs were adjusted the lead of fabric and position, drop-down clutch for clutch control bar 14, connecting rod 17 made on the friction transfer roller 2 and lift composition from state under the effect of support bar 18.Unclamp clutch for clutch control bar 14, friction transfer roller 2 recovers the frictional fit state under the effect of extension spring 1.
