AI Technical Summary
Due to long-term high-speed operation, the presser presser mechanism of the existing embroidery machine is prone to loosening or deformation, which affects the working accuracy.
A kind of embroidery machine pressure foot -oriented linkage mechanism is designed to drive the three -eye connecting rod and a straight link through the camwheel to drive up and down blocks to slide up and down from the vertical axis, and move the block up and down to stabilize the driving foot mechanism. At the same time, the coordination of the guide wheel and pulley ensures the stability of the motion trajectory of the entire linkage agency.
The design stabilizes the driver's foot pressing mechanism, improves the accuracy of the work, and extends the service life, avoiding the occurrence of looseness and deformation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of embroidery machines, in particular to a presser foot guide linkage mechanism of an embroidery machine. Background Art
[0002] The presser foot mechanism of the existing embroidery machine is basically driven by a cam mechanism to link multiple connecting rods. During the linkage process, the multiple connecting rods often become loose or deformed due to long-term high-speed operation, thereby affecting the working accuracy of the presser foot. Utility Model Content
[0003] The utility model discloses a presser foot guide linkage mechanism for an embroidery machine, which can stably drive the presser foot mechanism. The specific technical scheme is as follows:
[0004] The invention discloses an embroidery machine presser foot guide linkage mechanism, comprising a cam mechanism with a cam connecting rod, wherein the cam connecting rod is connected to the middle fulcrum of a three-eye connecting rod, one end of the three-eye connecting rod is fixedly connected to a machine casing, and the other end is connected to a straight connecting rod A, the straight connecting rod A is connected to an upper slider on a vertical axis, the upper slider is connected to a lower slider on the vertical axis through a straight connecting rod B and a straight connecting rod C connected end to end, and the head of the lower slider is provided with a toggle block for toggling the presser foot of the embroidery machine; a guide wheel A is provided at the connection between the straight connecting rod B and the straight connecting rod C, and the guide wheel A cooperates with a curved guide groove in a guide plate A fixed on the side of the machine casing.
[0005] The lower slider is provided with a pulley B which cooperates with a straight sliding groove in a guide plate B fixed on the other side of the housing.
[0006] The cam mechanism of the utility model drives the three-eye connecting rod through the cam connecting rod, and then drives the upper slider to slide up and down on the vertical axis through the straight connecting rod A; the upper slider drives the lower slider to slide up and down on the vertical axis through the straight connecting rods B and C, driving the toggle block of the head of the lower slider to toggle up and down, thereby driving the presser mechanism to work; at the same time, the guide wheel A at the connection between the straight connecting rod B and the straight connecting rod C slides along a track in the curved guide groove of the guide plate A on the side of the casing; the pulley B of the lower slider slides up and down in the straight sliding groove of the guide plate B on the other side of the casing, thereby stabilizing the motion track of the entire linkage mechanism, ensuring the normal operation and accuracy of the entire linkage mechanism, and ensuring the service life.
