[0001] The utility model belongs to the technical field of pleating presser feet, in particular to a thin material pleating presser foot of a sewing machine. Background Art
[0002] In clothing production, pleating is a common process. Commonly used equipment includes sewing machines, pleating machines and pleating machines. Among them, sewing machines, as a simple and commonly used pleating equipment, play a vital role in the clothing production line. The sewing machine presser foot, as the core component of the sewing machine feeding mechanism, is a key factor in ensuring sewing quality and pleating effect.
[0003] The presser foot of a sewing machine will rise and fall with the needle. The fabric moves when the presser foot rises, and flattens the fabric when the presser foot falls to form stitches. The existing sewing machine pleating process requires the fabric to be pressed down by hand all the time, and the presser foot has a single shape and cannot adjust the pleat shape. For this reason, we propose a thin material pleating presser foot for a sewing machine. Utility Model Content
[0004] In order to solve the problems that the current sewing machine pleating process requires the fabric to be pressed down by hand all the time, and the presser foot has a single shape and cannot adjust the pleat shape, the utility model provides the following technical solution: a thin material pleating presser foot of a sewing machine, comprising a presser foot handle, a connecting piece is provided at the bottom of the presser foot handle, a presser foot plate is provided at the bottom of the connecting piece, a pressure spring is provided on the connecting piece, a pressure adjusting knob is provided on the pressure spring, a support rod is provided on the presser foot handle, an auxiliary pleating mechanism is provided on the support rod, and the auxiliary pleating mechanism is used to press down the fabric.
[0005] Preferably, the pressure adjustment knob is provided with a scale code so that the user can adjust the pressure more accurately, and a higher pressure will produce tighter pleats, while a lower pressure will produce looser pleats.
[0006] Preferably, the auxiliary pleating mechanism is a rubber stick, which is fixedly connected to the support rod and has a relatively low cost.
[0007] Preferably, the auxiliary pleating mechanism comprises a spring, a steel ball is connected to the bottom of the spring, and the support rod is fixedly connected to the spring for better stability.
[0008] Preferably, the auxiliary pleating mechanism is a telescopic support rod, and the support rod is fixedly connected to the telescopic support rod, which has better flexibility.
[0009] Preferably, a locking piece is provided on the pressure regulating knob to maintain a constant pressure.
[0010] Preferably, the presser foot plate is provided with straight grooves and wavy grooves to adjust the pleat shape.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] When working, first install the presser foot handle on the sewing machine, adjust the pressure adjustment knob to achieve the desired pleat effect, and move the presser foot plate above the fabric to ensure that the presser foot plate can press the fabric tightly. Choose to use straight grooves or wavy grooves as needed, and turn on the sewing machine. In the first embodiment, the user can occasionally move the rubber stick to assist in pleating. In the second embodiment, the user can move the spring to prevent the pleated fabric from piling up. In the third embodiment, the user can manually adjust the length of the retractable support rod to prevent the fabric from piling up in a specific position and help form wrinkles. After sewing is completed, the user can lift the presser foot plate by moving the presser foot handle to take out the finished fabric. There is no need to press the fabric with hands all the time during the pleating process, and the pleat type can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
