Description
Technical field:
The present invention relates to the sewing machine product technical field, refer in particular to a kind of stablely, smooth and easy, and sewing quality is good, the efficient sewing machine of high life.
Background technology:
Sewing machine is also referred to as disk sewing machine, is commonly called as the running-on car, uses suture to sew up the machine of sweater running-on.Can finish efficiently, fast the garment piece stitching work of sweater by sewing machine, greatly improve than the efficient of manual suture.Sewing machine can with the sweater sheet, comprise that the front width of cloth, back panel, sleeve, chest subsides, bag and other accessory unite by a seam.It is to decide according to every cun shared suture needle quantity of seam dish circumference that its pin number is divided.
Traditional sewing machine ride structure is open by design, it comprises a casing and is installed on the interior gear assembly of casing, make casing in the ride substantially can not oil storage or the trapped fuel amount seldom, oiling method is to carry out oil dripping by oil bottle, thereby realize gear assembly is refueled, although play the purpose of oiling.But inconvenient, the oil mass of can occurring refueling is difficult to the problems such as control.In addition, gear assembly is fixing assembling, can not adjust the relative distance of parts in the gear assembly, and the gear in the gear assembly adopts bevel gear, gear assembly is in the process of running up, bevel gear wearing and tearing, the phenomenon such as stuck, loosening can occur, make whole gear assembly move and have some setbacks, have a strong impact on the work quality of sewing machine.
Generally use the conveyer belt transmission in the sewing machine, engagement by conveyer belt and gear with transmission of power to the Working mechanism of sewing machine, conveyer belt produces to produce easily when running up beats, and conveyer belt in use for some time, conveyer belt can produce loosening, rate of tension can reduce, easily produce the phenomenon such as beat, it is not steady to work, if change frequently conveyer belt then can cause the waste of resource, also cause cost to improve, in addition, the double wedge that arranges on traditional conveyer belt generally is zigzag, like this so that conveyer belt and driving wheel, friction between the driven pulley is larger, the ability that friction consumes is more, and heating is large.
The indexing means used of tradition sewing machine comprises: the pin arm axle, be socketed on swing arm and spring on the pin arm axle, be fixed in the pin arm of pin arm axle end, and be positioned at swing arm side and the auxiliary drive inconsistent with the swing arm side.Wherein, directly conflict in a side of spring one end and swing arm, and auxiliary drive is direct and conflict in the another side of swing arm.During indexing means work, swing arm swings back and forth at a high speed, swings back and forth at a high speed with the driving needle arm, realizes the sewing action.In swing arm swings back and forth at a high speed process, spring one end and swing arm constantly rub, swing arm or spring can wear and tear, have a strong impact on the elastic force of spring, in addition, the another side of swing arm also can make its wearing and tearing with the auxiliary drive friction, therefore, the indexing means that the tradition sewing machine is used is short service life, and can produce larger noise, affects the performance of whole machine.
Tradition sewing machine push rod transmission mechanism, it comprises: pedestal, be installed on push rod in the pedestal, be revealed in the outer end of pedestal in this push rod and be used for inconsistently with the cam of sewing machine, the other end is used for inconsistent with the centering block of sewing machine, wherein, the push rod two ends are arc surface.When the push rod transmission mechanism was worked, the cam of sewing machine swung by the top rod driving centering block, and namely push rod slidably reciprocates in the pedestal high speed, and push rod two ends difference is continuous and cam and the centering block friction of sewing machine.Because the lifting surface area of cam and centering block is little, can cause cam and centering block constantly to wear and tear, affects the amplitude that centering block swings, thereby can affect sewing quality and the efficient of whole Sewing machines.
During sewing machine work, the drive disk assembly of sewing machine can run up, and in order to make the sewing machine operation smooth and easy, then needs drive disk assembly is refueled.Traditional oiling method is by the oil bottle oil dripping, thereby realizes drive disk assembly is refueled, although play the purpose of oiling.But inconvenient, the oil mass of can occurring refueling is difficult to the problems such as control.
