Problems solved by technology

When the pulling force of the return spring is large or the torque of other linkage mechanisms is large, the electromagnet is slow or unable to attract, which makes the machine not work normally and affects the performance of the machine, and the attraction force of the electromagnet cannot be adjusted freely.

Abstract

The invention relates to a middle presser foot lifting mechanism for a pattern stitching machine. The mechanism comprises a filter, an electromagnetic valve, a cylinder and a cylinder connector, wherein the cylinder is fixed on a cylinder mounting bracket; the filter and the electromagnetic valve are fixed with a frame respectively; a first pipe joint of the filter is connected with a first pipe joint of the electromagnetic valve through a first air pipe; a second pipe joint of the electromagnetic valve is connected with a pipe joint of the cylinder through a second air pipe; a second pipe joint of the filter is connected with an external air power source through a third air pipe. The presser foot lifting mechanism has advantages that whether the electromagnetic valve is switched on or off, a piston rod of the cylinder is always stressed, so that the whole middle presser foot lifting mechanism has quick response; and the tensile force of the piston rod can be adjusted through regulating the volume of working air pressure through the filter.

Description

technical field [0001] The invention relates to a pattern machine, in particular to an intermediate presser foot lifting mechanism of the pattern machine. Background technique [0002] Electronic pattern machine is a special clothing equipment for bags, leather, labels, etc., which is mainly used for their decorative sewing. [0003] The machine uses a direct-drive servo motor to drive the upper shaft, and the X-axis and Y-axis are both driven by stepping motors. Programming is performed through programming software or the operation panel, and computer control is used to complete various patterns of sewing equipment. [0004] The lifting mechanism of the intermediate presser refers to the mechanism that uses the electromagnet as the power source to complete the lifting or lowering of the intermediate presser through other linkage mechanisms. [0005] Depend on figure 1 It can be seen that the control device of the pneumatic intermediate presser foot lifting mechanism of th...
