Abstract
The utility model discloses an embroidery machine presser foot driving mechanism which comprises a transmission main shaft, a presser foot cam, a presser foot rod, a spring I and a spring II, wherein the presser foot cam is connected with a moving rack; the upper part and the lower part of the moving rack are sleeved on the presser foot rod; the presser foot rod is arranged on the head of an embroidery machine; a presser foot is arranged at the bottom of the presser foot rod; the spring I is sleeved at the upper part of the presser foot rod; the upper end of the spring I props against the head of the embroidery machine; the lower end of the spring I props against the upper end of the moving rack; the spring II is sleeved in the middle of the presser foot rod and is positioned inside the moving rack; the upper end of the spring II props against the upper part inside the moving rack; the lower end of the spring II is connected with a fixed plate fixed on the presser foot rod; the inner side of the lower part of the moving rack is detachably connected with the bottom side of the fixing plate. By adopting the embroidery machine presser foot driving mechanism, the motion amplitude of the presser foot can be effectively reduced, the travel of the presser foot is reduced, the pressure intensity of the presser foot is increased, and the machining efficiency is improved.
Description
Technical field
The utility model relates to a kind of embroidery machine, particularly a kind of presser foot of embroidery machine driving mechanism.
Background technology
The presser feet of embroidery machine is to be all pressed on cloth by presser feet Spring driving presser feet by shank, so that when shank rollback, reach the standard grade and form wire loop at the eye of a needle place of eedle, rotating shuttle point hooks after this wire loop rotates a circle and just entangles bottom line, then reach the standard grade and tighten up, embroidery machine just completes a most basic thorn cloth action, produces a needle tracking on cloth.But existing presser feet driving mechanism is owing to sharing a main shaft with shank, drives shank and presser bar to move up and down by a main shaft simultaneously, thereby make the stroke of presser feet long, pressure is inadequate, is difficult to improve working (machining) efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, presser feet stroke is short, pressure is large, working (machining) efficiency is high presser foot of embroidery machine driving mechanism.
The utility model solves the technical scheme that its technical problem adopts:
A kind of presser foot of embroidery machine driving mechanism, includes: a transmission main shaft being horizontally installed on embroidery machine, has drive unit to drive this transmission main shaft rotation;
One presser feet cam, this presser feet cam is arranged in embroidering machine head and is sleeved on transmission main shaft, on described presser feet cam, is connected with adjustable shelf, and the upper and lower part of adjustable shelf is set on presser bar;
One is arranged at the presser bar on embroidering machine head, and the bottom of this presser bar is provided with presser feet;
One is set in the spring I on presser bar top, and the upper end of spring I withstands on embroidering machine head, and the lower end of spring I withstands on the upper end of adjustable shelf;
One is set in presser bar middle part and is positioned at the spring II of adjustable shelf inside, and the upper end of spring II withstands on the top of adjustable shelf inside, and the fixed head that the lower end of spring II and is fixed on presser bar is connected;
The inner side of described adjustable shelf bottom and fixed head bottom surface can deciliter be connected.
In the utility model, described adjustable shelf is connected with a guide rod, and guide rod parallels with presser bar.
In the utility model, described fixed head is connected with a guide rod, and guide rod parallels with presser bar.
In the utility model, the side of described adjustable shelf is provided with roller, and adjustable shelf is connected with presser feet cam by roller.
The beneficial effects of the utility model are: when embroidery, rotarily actuate presser feet cam, adjustable shelf motion by main shaft, in the time moving on adjustable shelf, the bottom of adjustable shelf drives fixed head and presser bar up to move, in the time that adjustable shelf moves down under the effect of spring I, adjustable shelf top pressuring spring II, spring II drives fixed head and presser bar to move down; This structure can effectively reduce the motion amplitude of presser feet, reduces the stroke of presser feet, increases the pressure of presser feet, improves working (machining) efficiency.In addition, adjustable shelf is that on-fixed is connected with presser bar, but drives fixed head and presser bar motion by spring II, cloth is thicker, and the compressed of spring II must be tighter, only otherwise the compressed limit of super spring II, thereby the cloth that can process different-thickness, applicability is strong.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated:
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is another angle structural representation of the present embodiment.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of presser foot of embroidery machine driving mechanism provided by the utility model, includes: a transmission main shaft 1 being horizontally installed on embroidery machine, has drive unit to drive this transmission main shaft 1 to rotate; One presser feet cam 2, this presser feet cam 2 is arranged in embroidering machine head and is sleeved on transmission main shaft 1, on described presser feet cam 2, be connected with adjustable shelf 3, described adjustable shelf 3 is " Contraband " font, the upper and lower part of adjustable shelf 3 is set on presser bar 4, drives presser bar 4 to do up and down motion by a small margin by the rotation of presser feet cam 2;
One is arranged at the presser bar 4 on embroidering machine head, and the bottom of this presser bar 4 is provided with presser feet;
One is set in the spring I 5 on presser bar 4 tops, and the upper end of spring I 5 withstands on embroidering machine head, and the lower end of spring I 5 withstands on the upper end of adjustable shelf 3;
One is set in presser bar 4 middle parts and is positioned at the spring II 6 of adjustable shelf 3 inside, the upper end of spring II 6 withstands on the top of adjustable shelf 3 inside, the fixed head 7 that the lower end of spring II 6 and is fixed on presser bar 4 is connected, and in the present embodiment, described fixed head 7 is connected on presser bar 4 by screw
