Abstract
The utility model discloses a sewing machine crank thread-taking-up mechanism which includes a thread-taking-up crank body; and a thread-taking-up hole is arranged in the crank body. The sewing machine crank thread-taking-up mechanism is characterized in that a plane is arranged on the crank body; the included angle alpha between the plane and the central line of the thread-taking-up hole is 4-5 degrees. In the scheme, as the plane is arranged on the crank body and the included angle alpha between the plane and the central line of the thread-taking-up hole is 4-5 degrees, the stroke of the needle pole of the sewing machine is enlarged, and the line adjusting stroke is enlarged, thereby leading the crank body to be suitable for cloths with different thicknesses, thus meeting the different requirements of thin materials and thick materials on the sewing machine, and reaching the effects of multi-function through one machine. The sewing machine crank thread-taking-up mechanism has large applicable scope and reduces cost investment.
Description
Technical field
The utility model relates to Sewing machines, particularly relates to the crank thread take-up mechanism of Sewing machines, belongs to the garment machinery field.
Background technology
Sewing machines is according to the cloth thickness difference of making, the suture difference of use, thus make the model that bar mechanism also should expect the thickness of cloth and have many kinds to be suitable for of choosing of Sewing machines.But the problem that present clothing enterprise faces is little and wide in variety in batches order, and their required models are a lot, if procuring equipment, utilization rate is but very low, and the words of not purchasing but do not satisfy required requirement.Such contradiction is ubiquity in clothing enterprise, and has influence on the productivity effect of each clothing enterprise, is restricting the development of garment enterprise.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of one-machine-multi-function to be provided, and is applied widely, improves utilization rate of equipment and installations, utilizes existing equipment to greatest extent, reduces the Sewing machines crank thread take-up mechanism of cost investment.
The technical scheme of the utility model Sewing machines crank thread take-up mechanism is: comprise the thread take-up crank main body, be shaped on the take-up hole in the crank main body, it is characterized in that being shaped on the plane on the described crank main body, the angle α of plane and take-up centerline hole is 4 °-5 °.
Sewing machines crank thread take-up mechanism of the present utility model, owing on the crank main body, be shaped on the plane, the angle α of plane and take-up centerline hole is 4 °-5 °, make the stroke of needle bar of sewing machine become big, it is big that the line transfer stroke becomes, thereby make the crank main body adapt to the cloth of different thickness, satisfied from approaching and expected of the different requirements of thick material Sewing machines, reached the effect of one-machine-multi-function, applied widely, reduce cost investment.
Sewing machines crank thread take-up mechanism of the present utility model, the angle α of described plane and take-up centerline hole is generally 4.5 °, but allows positive and negative 0.5 ° error.
Description of drawings
Fig. 1 is a Sewing machines crank thread take-up mechanism structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to schematic cross-section.
The specific embodiment
The utility model relates to a kind of Sewing machines crank thread take-up mechanism, as shown in Figure 1 and Figure 2, comprise thread take-up crank main body 1, be shaped on take-up hole 2 in the crank main body 1, it is characterized in that being shaped on plane 3 on the described crank main body 1, plane 3 is 4 °-5 ° with the angle α of take-up hole 2 center lines.This programme is owing to be shaped on plane 3 on crank main body 1, plane 3 is 4 °-5 ° with the angle α of take-up hole 2 center lines, make the stroke of needle bar of sewing machine become big, it is big that the line transfer stroke becomes, thereby make the crank main body adapt to the cloth of different thickness, satisfied from thin and expected of the different requirements of thick material, reached the effect of one-machine-multi-function Sewing machines, applied widely, reduce cost investment.Described plane 3 is generally 4.5 ° with the angle α of take-up hole 2 center lines, but allows positive and negative 0.5 ° error.
Claims (2)
