Density adjusting device of sleeve lace machine

The utility model relates to the related technical field of textile machinery, in particular to a density adjusting device of a sleeve lace machine, which comprises a motor seat, a linear motor screwed on the surface of the motor seat, an output shaft in power connection with the power output end of the linear motor, a main fixing sleeve welded on the surface of a mounting plate, and an outer fixing plate screwed inside the sleeve lace machine. The sleeve lace machine has the beneficial effects that the outer fixing plate is connected to the surface of the linear motor and the interior of the sleeve lace machine in a threaded mode, the inner telescopic plate slides up and down in the outer fixing plate, dustproof protection is achieved through the inner telescopic plate and the sealing top plate, and the inner telescopic plate can slide up and down in the outer fixing plate; when the density is adjusted, a pneumatic push rod is started to enable an inner telescopic plate to move up and down, then it is guaran
