Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing equipment technology, and in particular to an automatic small collar sewing machine. Background Technology

[0002] Small collars typically refer to designs with a smaller neckline, commonly found in various garments. They serve to flatter the neckline and enhance a sense of refinement. During the garment-making process, small collars require processing using a sewing machine. Usually, the edges of the small collar fabric that need to be sewn are turned inside out and then sewn in place to ensure a smooth and clean surface without unevenness, preventing deformation or curling, and maintaining a crisp collar shape.

[0003] Currently, most processing is done semi-manually. After manually picking up the small collar, the edges are folded and then processed by a sewing machine before being manually cut into pieces. The whole process is labor-intensive, has low production efficiency, and is prone to injury from touching the sewing machine's cutting head during the picking and placing process. Utility Model Content

[0004] This utility model provides an automatic small collar sewing machine, which can automatically feed and transport small collars during the small collar sewing process. During the transport process, the small collar that needs to be sewn is automatically flipped and adjusted before sewing, eliminating the need for manual flipping and adjustment. The fully automatic processing improves production efficiency and avoids the situation of accidental bumps and scratches that are easily caused by manual flipping.

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic small collar sewing machine, comprising: The workbench is equipped with a feeding port; An electric lead screw includes an output rod, the end of which is connected to a push plate; A sewing machine equipped with a sewing head; A special drawing tube includes a feeding chamber, a conveying chamber, and a blowing pipe. The feeding chamber is connected to the conveying chamber and both are provided with a conveying chamber inside. The blowing pipe passes through the feeding chamber and is located near one end of the conveying chamber.

[0006] As a preferred embodiment of the above technical solution, the worktable surface is provided with a scale plate, and the push plate is slidably connected to the worktable surface.

[0007] As a preferred embodiment of the above technical solution, the sewing machine is further provided with a sewing board and an infrared sensor. The sewing head is located on the top of the sewing board, the infrared sensor is located on the top of the sewing head, a cutting blade is provided at the bottom of the sewing board and the cutting blade penetrates through the sewing board, and a hydraulic lifting rod is provided at the bottom of the cutting blade.

[0008] As a preferred embodiment of the above technical solution, one end of the blower extends to the outside of the feed chamber and is connected to an air compressor. The bottom surface of the blower is uniformly provided with air holes, which are inclined and the inclination angle is directed toward the conveying chamber. The conveying chamber inside the feed chamber is located at the bottom of the blower.

[0009] As a preferred embodiment of the above technical solution, the two ends of the conveying cavity are respectively configured as an inlet and an outlet, the inlet is connected to the feeding cavity, the length of the inlet is greater than the length of the outlet, and a limiting baffle is provided between the inlet and the outlet.

[0010] As a preferred embodiment of the above technical solution, a first monitoring groove is provided through the bottom surface of the feeding chamber, and a second monitoring groove is provided through the top surface of the conveying chamber. Infrared sensors are provided on the outside of both the first and second monitoring grooves.

[0011] As a preferred embodiment of the above technical solution, a feeding plate is connected to the outside of the workbench, and the feeding plate is used to connect to the feeding conveyor belt.

[0012] As a preferred embodiment of the above technical solution, a positioning groove is fixedly provided on the surface of the worktable, and a movable rod is slidably provided inside the positioning groove. The movable rod is fixedly connected to the output rod of the electric lead screw, and a limiting block is provided at the end of the movable rod. The width of the limiting block is greater than the width of the positioning groove.

[0013] As a preferred embodiment of the above technical solution, the workbench surface is provided with a control panel, and the control panel contains a PLC controller and a data transmission module.

[0014] This invention provides an automatic collar sewing machine, which includes an electric lead screw, a push plate, a sewing machine, and a special pull tube. The collar to be sewn is conveyed from the feed plate into the feed chamber of the special pull tube. When the collar reaches the bottom of the air blower, an infrared sensor at the bottom of the first monitoring slot detects the fabric conveying. An air inflator connected to the outside of the air blower then blows the collar into the conveying chamber. During this gradual movement within the conveying chamber, the internal space gradually decreases, and under the constraint of the limiting folding plate, the edge of the collar to be sewn folds over the top of the main fabric and moves out of the conveying chamber into the bottom of the sewing machine, where it is then monitored by a sensor installed at the top of the second monitoring slot. Infrared sensors monitor whether the fabric is fed evenly and provide timely feedback. As the fabric reaches the designated position, the sewing head quickly sews and cuts the thread to complete the sewing. At this time, the electric push rod lifts the pressure plate to remove the limiting pressure on the collar. The electric screw drives the push plate to move and push the sewn collar out of the sewing machine's working area so that it can be unloaded through the feed port. This enables automatic feeding and conveying of the collar during the sewing process. During the conveying process, the parts of the collar that need to be sewn are automatically flipped and adjusted before sewing, eliminating the need for manual flipping and adjustment. This fully automatic processing improves production efficiency and avoids the risk of accidental bumps and scratches caused by manual flipping.
