Problems solved by technology

[0002] Sewing machines on the existing market generally use stepping motors to control the swinging seat to adjust the stitch distance, but stepping motors or electromagnets are used to control the presser foot lifting and thread trimming actions respectively. The configuration of multiple motors leads to the sewing machine. The power utilization rate decreases, and at the same time, the manufacturing and assembly are complicated, which leads to an increase in the cost of the sewing machine, and the operation of multiple motors also makes the sewing machine have a large heat dissipation, which shortens the service life of the sewing machine. The motor controls the sewing machine that adjusts the stitch distance, presser foot and thread trimming to improve the working efficiency of the whole machine and reduce the manufacturing cost

Embodiment 1

[0028] figure 1 It is a schematic diagram of an intelligent multifunctional sewing machine of the present application, which has a power source 10. The power source 10 is a power device with dual output power. The power source 10 has a front output shaft 11 and a rear output shaft 12. The power source 10 rotates and drives the front The output shaft 11 and the rear output shaft 12 are rotated. The power source 10 of the present application controls the thread trimming action of the thread trimming mechanism 20 through the front output shaft 11 , and controls the reverse stitch adjustment mechanism 30 , the presser foot lifting mechanism 40 and the thread release mechanism 50 through the rear output shaft 12 . Needle distance adjustment action, presser foot lift action and thread release action; achieve the technical effect that the above-mentioned sewing actions are completed by one power source 10 at different times and in different areas, so that the sewing machine has the p...

Embodiment 2

[0047] The second embodiment is basically the same as the above-mentioned first embodiment, the difference is that the rear output shaft 12 controls the reverse stitch length adjustment mechanism 30 , the presser foot lifting mechanism 40 and the thread release mechanism 50 . , Lifting the presser foot and loosening the thread, the rear output shaft 12 is fixed with a composite transmission wheel 13 and a presser foot lifting thread cam 15. This solution does not have a separate thread trimming mechanism 20, and other contents are the same as in the first embodiment. The technical effect is the same.

Embodiment 3

[0049] The third embodiment is basically the same as the above-mentioned first embodiment, the difference is that the composite transmission wheel 13 is arranged in a separate type, and the Figure 8 Figure 9 Figure 10 Among them, the composite transmission wheel is divided into three parts, which are composed of a composite transmission wheel inner limiting plate 1a3, a composite transmission wheel base plate 1b3 and a composite transmission wheel outer buckle plate 1c3, but the above-mentioned composite transmission is still required to realize the scheme of the present application. The wheel inner limiting plate 1a3, the composite transmission wheel base plate 1b3 and the composite transmission wheel outer gusset plate 1c3 are recombined into a whole to become a complete composite transmission wheel to realize the function of the first embodiment. There are various methods to make the composite transmission wheel inner limit plate 1c3 1a3 and the outer gusset plate 1c3 o...

Abstract

The invention provides an intelligent multifunctional sewing machine, and particularly relates to the technical field of sewing machine manufacturing. The intelligent multifunctional sewing machine isprovided with a power source; the power source is provided with a rear output shaft; the rear output shaft is used for controlling a backstitching stitch length adjusting mechanism, and the intelligent multifunctional sewing machine is characterized in that a composite transmission wheel is fixed to the rear output shaft, and an operation groove formed in the composite transmission wheel acts ona crank. The power source is used for executing backstitching stitch length adjustment, the operation efficiency of the backstitching stitch length adjusting mechanism is brought into full play, the intelligent control level is improved, programmed control over all sewing actions is achieved, the assembly efficiency is improved in manufacturing, the failure rate of a special power source of the whole sewing machine is reduced, and therefore the performance of the whole sewing machine is improved.

Description

technical field [0001] The present application proposes an intelligent multifunctional sewing machine, which specifically relates to the technical field of sewing machine manufacturing. Background technique [0002] Sewing machines on the existing market generally use stepper motors to control the swing seat to adjust the stitch length, but stepper motors or electromagnets are used to control the action of lifting the presser foot and trimming the thread respectively. The configuration of multiple motors results in the entire sewing machine. The power utilization rate is reduced, and the manufacturing and assembly are complicated, which leads to an increase in the cost of the sewing machine. The operation of multiple motors also causes the sewing machine to dissipate heat and shorten the service life of the sewing machine. In view of the above situation, a stepper by a stepper has been developed. Motor-controlled sewing machines for stitch length adjustment, presser foot and...
