The invention provides a sewing material thickness detection device. The device comprises an electronic control module, a main motor, a detection sensor, a detected piece, a connecting lever frame anda detection piece, wherein the detected piece is arranged opposite to the detection sensor, the connecting lever frame is provided with a fixed swing fulcrum, and the detection piece is used for being in contact with a sewing material. The two ends of the connecting lever frame are provided with a first mounting part and a second mounting part respectively; the detected piece and the detection piece are mounted on the first mounting part and second mounting part of the connecting lever frame respectively; the detected piece, the fixed swing fulcrum of the connecting lever frame and the detection piece are sequentially arranged in the length direction of the connecting lever frame, and the detection sensor and the main motor are both connected with the electronic control module. During sewing, when the thickness of the sewing material is increased or decreased, the detection piece can ascend or descend correspondingly, so that output signals of the detection sensor are changed correspondingly; the electronic control module can judge whether the thickness of the sewing material is changed or not according to the output signals of the detection sensor and correspondingly reduce or increase the rotation speed of the main motor to ensure the sewing quality.

The invention provides a sewing material aligning unit of an automatic sewing device. The sewing material aligning unit comprises a table plate for installing a sewing machine, material pressing driving sources, material pressing pieces driven by the material pressing driving sources to move up and down, a material transfer manipulator, and material transfer pieces driven by the material transfer manipulator to move and used for driving a sewing material to move. The material pressing pieces and the material transfer pieces are positioned at an upper side of the table plate. When the material transfer pieces drive one corner of the sewing material to move to a position under the material pressing pieces, the material pressing driving sources drive the material pressing pieces to move downwardly and press the corner of the sewing material, and then the material transfer pieces drive the sewing material to move and deflect around the material pressing pieces. Aligning precision and accuracy of edges of the sewing material can be effectively improved, and therefore sewing quality of the sewing material is ensured. The sewing material aligning unit is simple in structure and easy to control, and alignment of the sewing material is easy to implement.

The invention discloses a sewing method for a shoulder joint, which divides the sewing track of the sleeve joint into an upper sewing track and a lower sewing track; wherein, the upper sewing track is set to extend upward and the lower sewing track is set to extend downward; The left and right ends of the upper sewing track have a first extending edge extending toward the sewing edge, the left and right ends of the lower sewing track have a second extending edge extending toward the sewing edge, and the second extending edge is located above the first extending edge, So that: the left and right ends of the upper sewing track and the lower sewing track are correspondingly cross-connected; in this way, it is spliced ​​through two sections of cross-stitch sewing to avoid the entire sleeve and shoulder interface from being completely closed, ensuring the sewing quality of the sleeve and shoulder interface , which improves the simplicity and yield of sewing processing, is more suitable for automatic sewing processing, and has good processing feasibility.

The invention discloses a precise positioning type sewing machine for processing high-end leather shoes, comprising a sewing machine base and a groove, and the upper surface of the sewing machine base is provided with a groove; Cooperate with each other to drive the moving plate to move in the horizontal direction, so as to sew the upper in the horizontal direction. By setting the electric push rod, the slider is pushed to move in the vertical direction, so as to sew the side of the shoe in the vertical direction. The whole process does not require Manually fix and move the shoes, with high work efficiency; by setting the spring at the lower end of the shoe groove, the spring squeezes the placing plate, and the leather shoes are fixed under the pressing between the placing plate and the upper top plate, which avoids the shoes from moving during the sewing process. The cross needle groove plays a guiding role for the sewing needle to ensure the sewing quality; by moving the gear lever, the distance and size of the cross needle groove can be adjusted, so that the stitch length of each leather shoe is the same, and the defective rate of leather shoes can be reduced.

The invention discloses an elastic cord positioning sewing device and a sewing method in garment processing. An electric sewing machine is divided into a body and a machine base. A guiding support mechanism is arranged on the right side of the upper end of the electric sewing machine base, and a working plate is arranged on the upper end of the guiding supporting mechanism. , the sewing guide mechanism is set on the right side of the electric sewing machine base, and is fixedly connected with the right side of the working plate, the sewing positioning mechanism is set on the upper right side of the working plate, the conveying mechanism is set on the left side of the working plate, and the pressing mechanism is set It is located at the right end of the conveying mechanism, and is set in cooperation with the sewing needle structure on the body of the electric sewing machine. The adsorption fixing mechanism is set at the bottom of the pressing mechanism; it can compress the edge of the sewing position of the garment and the elastic cord, and can hold the garment and the elastic cord together. The overall sewing operation along the sewing direction can accurately grasp and quickly release the elastic cord. The positioning of the elastic cord is accurate, reasonable and efficient, which ensures the quality of sewing, reduces the workload of personnel, and improves the efficiency of positioning and sewing.

The invention relates to the technical field of sewing machine equipment, and specifically relates to a double tension wire clamping device. The double tension wire clamping device comprises wire clampers, a wire clamper fixing plate, a wire loosening plate A, a wire loosening plate B, a wire loosening plate shaft pin, a wire loosening plate shaft pin sleeve, first screws and a second screw. The wire clampers comprise four sets including a first coarse adjustment wire clamper, a second coarse adjustment wire clamper, a first fine adjustment wire clamper and a second fine adjustment wire clamper. The wire loosening plate A is fixed to the wire clamper fixing plate via the first screws. The wire loosening plate B is disposed between the wire loosening plate A and the wire clamper fixing plate and abutted against the wire loosening plate A. The wire loosening plate B is fixed to one end of the wire loosening plate shaft pin via the second screw, and the other end of the wire loosening plate shaft pin passes through the wire clamper fixing plate and is in interference clearance fit with the wire loosening plate shaft pin sleeve. Through a mode combined with coarse adjustment and fine adjustment, thread tension is extremely easy to adjust, appropriate tension of each thread is ensured, consistent tension of two threads is also ensured, and sewing quality is effectively ensured.
