The utility model provides a thick and thin material detection device of a sewing machine, which comprises a machine shell, a Hall sensor fixed on the machine shell through a sensor support is arranged in the machine shell, and magnetic steel connected with a pressing rod guide frame through a magnetic steel support is arranged in the machine shell. According to the sewing machine applying the thick and thin material detection device, the pressure of the presser foot can be automatically adjusted in real time according to the thickness change of the sewing material, and the working mode of the sewing machine can be adjusted according to the thickness change of the sewing material, so that when sewing materials with different thicknesses are sewn, the problems of no ridge crossing, thin material wrinkling, thick material stitch skipping or thread breaking and the like are not prone to occurring, and the sewing efficiency is improved. The sewing machine with the thick and thin material detection device has the advantage of being good in sewing effect.

This application provides an automatic powder applicator and sewing equipment. The automatic powder applicator includes a powder box and a traction device located on one side of the powder box. The traction device is used to pull out a support strip wound on a material cylinder. The powder box has a receiving space and an inlet and an outlet communicating with the receiving space. The receiving space is used to hold lubricating powder. The inlet is used for the pulled-out support strip to enter the receiving space. The outlet is used for the pulled-out support strip to pass through the receiving space to adhere lubricating powder. The automatic powder applicator achieves automated control of lubricating powder adhesion to the pulled-out support strip, saving labor costs and improving work efficiency compared to manually adhering lubricating powder to the support strip; the lubricating powder is placed in the powder box, preventing waste and significantly improving the effective utilization rate of lubricating powder, thus saving lubricating powder costs.

The utility model discloses a redundancy mechanism for a patch pocket machine, which comprises a first pressure plate, a first retainer plate and a retainer worktable, and is characterized in that the first pressure plate is connected with a first cylinder, a cylinder body of the first cylinder is mounted on a first moving plate, the first moving plate is connected with a second cylinder, and the second cylinder is mounted on the retainer worktable. A cylinder body of the second cylinder is mounted on the first mounting plate; the first retainer plate is mounted on the front side of the retainer plate worktable, a second moving plate is arranged below the retainer plate worktable, a third air cylinder is arranged on the second moving plate, and a driving rod of the third air cylinder is connected with the retainer plate worktable. The second air cylinder drives the first material pressing plate to move to the position above the first material supporting plate, the first air cylinder drives the first material pressing plate to downwards press the large body fabric, the third air cylinder drives the material supporting workbench to downwards move, the material supporting workbench drives the first material supporting plate and the first material pressing plate to clamp the large body fabric, and the middle of the large body fabric is driven to be folded downwards to form redundancy. And the sewing effect of the pocket mouth is optimized.

The utility model provides a double crank mechanism embroidery machine head relates to sewing embroidery technical field, including the casing, be equipped with the presser foot drive crank in the casing, the presser foot drive crank is connected with needle bar drive crank through same transmission shaft fixedly. Adopt double crank mechanism respectively simultaneously drive needle bar main part and presser foot main part, can make both sides keep a balanced state of opposition in the movement, the movement between two cranks can offset each other axial centrifugal swing, effectively control the vibration produced in axial, reduce the vibration and noise produced when equipment works. Through the coordinated transmission between control connecting rod, make presser foot main part cloth time meet the cooperation between the sewing mechanism, effectively improve the sewing performance. Through a plurality of connecting rod transmission, make presser foot main part and needle bar main part's movement more coordinated, in the both separation and contact instant is in the same speed state, reduce the vibration produced between the impact when mechanism movement, reduce noise and improve the sewing quality.

The application provides a sewing machine with adjustable fabric penetrating stroke and a control method thereof. The sewing machine with adjustable fabric penetrating stroke comprises a main shaft, a needle bar, a connecting column fixed on the needle bar, a needle bar connecting rod, an adjusting driving motor, an eccentric part fixed on the end of the main shaft, a stroke adjuster, and a stroke adjusting assembly. One end of the needle bar connecting rod is hinged to the connecting column. The eccentric part is provided with an eccentric shaft part eccentric to the rotation center of the main shaft. The stroke adjuster is rotatably installed on the eccentric shaft part. The adjusting driving motor is connected to the stroke adjuster through the stroke adjusting assembly. The other end of the needle bar connecting rod is hinged to the stroke adjuster. The connecting points of the stroke adjuster and the stroke adjusting assembly, the connecting points of the stroke adjuster and the eccentric shaft part, and the connecting points of the stroke adjuster and the needle bar connecting rod are distributed in dislocation. The application can switch different fabric penetrating strokes on a single sewing machine to achieve better sewing effect, expand the sewing adaptation range of the single sewing machine, and improve the use experience of the whole machine.
