Abstract

The invention relates to an oil-free and high-speed sewing machine without lubrication device, belonging to sewing machinery, which is characterized in that: a motor is connected with the other end of the lower shaft of a bearing support via a shaft coupling; two synchronous pulleys are arranged on the lower shaft; wherein, one synchronous pulley is connected with the synchronous pulley arranged at the other end of the upper shaft via a synchronous belt, and the other synchronous pulley is connected with the synchronous pulley arranged on the rotary shuttle shaft of the bearing support via a shaft coupling. The invention has the advantages of gearless drive of the drive system, no lubrication, no pollution to the sewing material, higher clothing production grade and long service life.

Description

Non-oil rapid flush joint machine

Technical field:

The invention belongs to sewing device, be specifically related to a kind of non-oil rapid flush joint machine that does not need lubricating arrangement.

Background technology:

Traditional Sewing machines, its transmission system is to make the axle rotation by clutch motor by belt transmission, last axle is done shank by camshaft drive quadric chain and is pumped, last axle rotates rotating shuttle to lower shaft transmission of power by two pairs of bevel gears again, because rotating speed height, for reducing wearing and tearing, the raising heat dispersion between the driving member, need there be cumbersome lubricating system to guarantee, its shortcoming is easy oil leakage between the moving component, oil impregnate, pollute sewing, especially the clothes and the high-grade fabric of processing light color bring unnecessary loss to the user.

Summary of the invention:

The purpose of this invention is to provide a kind of lubricating system that do not need, pollution-free to sewing, can improve the garment production class, the non-oil rapid flush joint machine of long service life.

Technical scheme of the present invention is: a kind of non-oil rapid flush joint machine is by casing and base plate assembly unit; Being provided with shank in the casing joins by axle one end of going up in cam, quadric chain and the casing; The base plate downside is provided with lower shaft, the rotary shuttle shaft of motor and bearings; Establish on lower shaft one end and lift tooth mechanism up and down and feeding retainer one end joins, lower shaft also links to each other with feed spool by cam mechanism; Feed spool one end joins by the toggle and the feeding retainer other end, it is characterized in that: motor links to each other with the lower shaft other end of bearings by shaft coupling; Establish synchronous pulley on the lower shaft and be with synchronously with the synchronous pulley that last axle the other end is provided with and be connected, also establish synchronous pulley on the rotary shuttle shaft of synchronous pulley and bearings on the lower shaft and be with synchronously and be connected.

Because adopt technique scheme, the directly-drive servo motor is directly passed to lower shaft with power by shaft coupling, pass to axle and rotary shuttle shaft by synchronous band again, the transmission system gearless driving, need not to lubricate, thus have pollution-free to sewing, can improve the garment production class, the advantage of long service life.

Description of drawings:

Further specify technical scheme of the present invention below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the upward view of Fig. 1.

The specific embodiment:

With reference to figure 1, Fig. 2.A kind of non-oil rapid flush joint machine is by casing 1 and base plate 2 assembly units; Being provided with shank in the casing joins by axle 3 one ends of going up in cam, quadric chain and the casing; Base plate 2 downsides are provided with lower shaft 5, the rotary shuttle shaft 6 of motor 4 and bearings; Establish on lower shaft 5 one ends and lift tooth mechanism up and down and feeding retainer one end joins, lower shaft 5 also links to each other with feed spool 7 by cam mechanism; Feed spool 7 one ends join by the toggle and the feeding retainer other end, and motor 4 links to each other with lower shaft 5 other ends of bearings by shaft coupling 8; Establish synchronous pulley on the lower shaft 5 and be with 9 to be connected synchronously with the synchronous pulley that last axle 3 the other end are provided with, the synchronous pulley of also establishing on the lower shaft 5 on the rotary shuttle shaft 6 of synchronous pulley and bearings is with 10 to be connected synchronously.
