Embroidery machine presser foot system with three sets of axial-guide devices

Abstract

The invention discloses an embroidery machine presser foot system with three sets of axial-guide devices. The embroidery machine presser foot system comprises a needle bar driven by a needle bar driver and a pressure foot driver, wherein a transmission link is arranged between the needle bar driver and the pressure foot driver, the pressure foot driver is matched with a pressure foot, the pressure foot is connected with a needle bar in a sleeving manner, and a first set of axial-guide device is formed through the needle bar; the pressure foot driver is connected with a guide shaft in the sleeving manner to form a second set of axial-guide device relative to the pressure foot; the side edge of the pressure foot driver is connected with a guide bearing through a connection shaft, the periphery of the guide bearing is matched with a guide groove, and a third set of axial-guide device relative to the pressure foot is formed through the guide groove. According to the system provided by the invention, through the three sets of axial-guide devices, the pressure foot driver cannot generate radial rotation, and the pressure foot cannot twist even if twisting force of a spring is applied to the pressure foot, so that cloth pressing quality is improved and the service life of a link system is prolonged.

Description

technical field [0001] The invention relates to an embroidery machine presser foot system, in particular to an embroidery machine presser foot system with three sets of axial guide devices. Background technique [0002] At present, in the embroidery machine industry, the embroidery needles connected to the needle bars have hundreds of thousands of embroidery reciprocating processes every day. In this process, in order to ensure the embroidery quality, the presser feet around the embroidery needles need to be pressed once for each embroidery. The presser foot is sleeved and installed on the needle bar. The needle bar moves up and down through the connecting block and the needle bar driver. There is a spring between the presser foot and the connecting block or the limit block on the needle bar. The presser foot is driven by a spring. As the embroidery needle moves at high speed and needs to penetrate the cloth surface, if the presser foot moves with the needle bar at high spe...

Problems solved by technology

In the prior art, due to the certain torsion of the spring in the process of presser foot pressing, the presser foot will rotate slightly, and this rotation will be transmitted to the connecting rod system through the presser foot driver. Due to the frequent reciprocating motion, the continuous The torsion of the rod system seriously affects the service life of the connecting rod system. On the other hand, the slight twist of the presser foot is a fatal defect for high-grade fabrics, indicating that there is a problem with the guide of the presser foot. The current industry generally believes that there is no such thing as a guide for the presser foot. problem, and there is no solution to the torque of the presser foot, because once the torque of the presser foot is limited, the position of the presser foot must be limited, but this kind of limitation directly targeting the presser foot is obviously not feasible, and there is no such aspect Because the presser foot has been limited by the needle bar sleeve, it is not feasible to limit the position again, so there is currently no solution for the torque of the presser foot in the embroidery machine
