The computer control automation of actions of supplying, cutting, pressing and hooking the threads on the embroidering machine is realized, and the disadvantages of complicated structure, large volume, easy abrasion and large noise of the mechanical actuating mechanism in the original processing of the embroidery and knitting are solved. The utility model provides an operating mechanism for the computer embroidering machine. A coil, a fixed magnetic core and a movable magnet are arranged in the outer case of the operating mechanism. A propeller shaft can move along a shaft sleeve, and one end of a return device is connected with the propeller shaft. The utility model can be used in the computer embroidery machine, the computer drawnwork machine and the computer knitting machine.
Description
The utility model relates to a kind of computer embroidering machine electromagnet.
Give line, trimming, line ball and the hook line of embroidery machine are in the past finished by mechanical transmission mechanism, its complex structure, and volume is big, and easy to wear, and noise is big.
The purpose of this utility model is to rely on the effect of electromagnetic force to realize that the mechanical movement of transmission mechanism is to address the above problem.
The utility model center of being equipped with in shell (1) has the enamel-covered wire coil (2) of endoporus, magnetostatic iron core (5) and moving magnet (3) are housed in coil (2) endoporus, axle sleeve (4) and the coaxial stationary fit of magnetostatic iron core (5), power transmission shaft (8) can move along axle sleeve (4), moving magnet (3) is concentric and promote power transmission shaft (8) with magnetostatic iron core (5), one end of returning device links to each other with power transmission shaft (8), so that after electromagnetic force disappeared, power transmission shaft (8) can return original initial position.
Returning device of the present utility model can be an end effect be fixed in magnetostatic iron core (5) or shell (1) on, other end effect or be fixed in the spring (10) of power transmission shaft (8) also can be to rely on self gravitation to drive fall the back moving magnet (3) of initial position of power transmission shaft (8) in the axle sleeve (4) perpendicular to ground.
The bottom of the moving magnet (3) that power transmission shaft of the present utility model (8) is linked can be the some oblique grooves from shallow to deep that have along certain circle distribution, and corresponding with shell (1) bottom by being deep to shallow oblique groove, ball (16) wherein is housed, rotatablely moves so that do in the straight-line process to produce at power transmission shaft (8).
The utility model is converted into electromagnetic force to realize machine driving with electric pulse, its structure is little and simple, noise is little, wearing and tearing are few, can drive other mechanism to realize giving actions such as line, trimming, line ball, hook line in embroidery, drawn work, the knitting processing automatically under the control of computer.
Fig. 1 is that the utility model is used for the example structure schematic diagram that head is given line;
Fig. 2 is the example structure schematic diagram that the utility model is used for trimming;
Fig. 3 is the example structure schematic diagram that the utility model is used for line ball, hook line;
Fig. 4 is that the A of Fig. 3 is to cutaway view;
Fig. 5 is that the B of Fig. 3 is to cutaway view.
Further specify below in conjunction with accompanying drawing:
Its moving magnet of structure shown in Figure 1 (3) can move and promote power transmission shaft (8) under the effect of the formed electromagnetic field of coil (2), its servo corresponding executing agency (13) can finish the action that head is given line, control needle tracking size.The center of being equipped with has the enamel-covered wire coil (2) of the band skeleton (6) of endoporus in its cylindrical shell (1), be equipped with in coil (2) endoporus end and the friction tight magnetostatic iron core of shell (1) (5) and with the friction tight axle sleeve of magnetostatic iron core (5) (4), moving magnet (3) can move in axle sleeve (4), and by stop screw (7) promotion power transmission shaft (8) motion, stop screw (7) and moving magnet (3) are to be threaded, and the distance between can regulating, to determine the move distance of moving magnet (3) and power transmission shaft (8).The spacing termination of stop screw (7) is subjected to the elastic force of pressing spring (10) by power transmission shaft (8), make moving magnet (3) when initial position away from magnetostatic iron core (5).When having electric current to pass through in the coil (2), because the effect of formed electromagnetic field, moving magnet (3) promotes the elastic force that power transmission shaft (8) overcomes pressing spring (10) by stop screw (7), moves to the position that is adjacent to magnetostatic iron core (5).One end of magnetostatic iron core (5) bolt (9) is housed in case with servo embroidery machine be connected.Rubber ring (12) plays bumper and absorbing shock in moving magnet (3) motion, it is fixing by spring collar (11) and moving magnet (3).The outer end of power transmission shaft (8) acts on or is connected in the actuating mechanism (13) that is driven.
Structure shown in Figure 2 can match with actuating mechanism (13) scissors and finish the action of trimming.Its principle and structure basically identical shown in Figure 1, difference are, because its installation site as shown in Figure 2, so its returning device can rely on the own wt of moving magnet (3) to fall and make power transmission shaft (8) finish return.
Structure shown in Figure 3 is connected with actuating mechanism (13) crochet hook etc. can finish line ball, the action of hook line, its characteristics are because certain some oblique groove (Fig. 4 from shallow to deep of circle distribution in edge, bottom of the moving magnet (3) that power transmission shaft (8) is linked, shown in Figure 5), and corresponding with shell (1) bottom by being deep to shallow oblique groove, because of ball (16) is housed in the corresponding groove, so when power transmission shaft (8) during along axle sleeve (4) rectilinear motion, ball (16) rolls in the groove of shell (1) and the groove that promotes moving magnet (3) bottom makes power transmission shaft (8) produce the rotation of certain angle.Its returning device is a disc spring (10), and one end and power transmission shaft (8) are fixing, and the other end is connected with adjusting ring (15) on being fixed in magnetostatic iron core (5).Spring collar (14) defines the initial position of power transmission shaft (8).
