Abstract

The utility model discloses an embroidering machine motion rotary automatic bottom thread replacing device, which comprises two stepping electric motors; wherein, the stepping electric motor 1 is fixed on a machine foundation 4. A motor shaft is connected with a screw stem 2 so as to form a rigid body, and the screw stem 2 is connected with a spring clutch which is connected with a clamping device 8 to form the rigid body. The clamping device 8 is connected with a stepping electric motor 9 which is connected with a motion rotary arm 10. By adopting the shuttle cover to replace the screw shuttle, a worker only need to take out the replaced shuttle cover from the shuttle core and roll the bottom thread around a thread roller; after placing the shuttle on the shuttle bracket on the right lateral, the whole operation is finished. When the shuttle core of a second shuttle core has no bottom thread, the device can repeat the actions. The working intensity of the worker is greatly reduced; moreover, the time of replacing bottom thread by stopping the machine is shortened so as to realize the goal of improving the working efficiency of embroidering operation.

Description

The widely different rotatable line apparatus that refoots automatically of a kind of embroidery machine

Technical field

The utility model relates to the widely different rotatable line apparatus that refoots automatically of a kind of embroidery machine.

Technical background

Computerized emboridering machine is a kind of electromechanical integrated product that grows up on the Sewing machines basis, wherein, rotating shuttle is industry and domestic sewing machine, and the vitals of embroidery machine in each, it is the object of a concentric circles basically, outermost layer is the shuttle skin, and the housing that the shuttle skin is contained is rotating shuttle, and rotating shuttle is to be fixed on the rotary shuttle shaft usually.Its effect has two, and the one, the dress bottom line, the rotating shuttle nexine is a bobbin case, and the internal layer of bobbin case is a peg or spindle, and peg or spindle is used for adorning bottom line; The 2nd, collude upper thread, under the driving of rotary shuttle shaft, rotating shuttle rotatablely moves as circumference, has spur to be used for colluding upper thread on the shuttle skin, owing to limit by its volume, its external diameter has only 21 * 6.5 millimeters, the length of bottom line is generally 50 meters.So in case bottom line uses up, all there is a problem of often shutting down the line that refoots in above-mentioned machine at work, gives industrialized big production, has brought serious restriction.In embroidery machine (nearly 40 of numbers, first rotating shuttle) embroidery process, it is particularly outstanding that this problem seems especially, usually be that first stature has not had bottom line, machine stops automatically, and at this moment, the workman will bend to extract rotating shuttle under the platen of machine, bobbin case in the rotating shuttle is taken off, extract peg or spindle,, put into rotating shuttle again the peg or spindle that winds bottom line on the coil winding machine bobbin case of packing into, reload machine, could start operation like this.Machine works is after a period of time, and second stature has not had bottom line, and machine stops again automatically, and the workman will repeat the above-mentioned lineman of refooting once more and do.The embroidery machine of such one tens stature, the time of the line that refoots, the 30-40% of the whole working time that often accounts for has a strong impact on embroidery efficient.

Summary of the invention

The purpose of this utility model just provides a kind of raising embroidery machine production efficiency, utilizes refoot the automatically device of line of instantaneous stop.

The utility model is realized by following approach, it contains stepper motor, one of them stepper motor is fixed on the support, motor shaft and screw rod are connected to become a rigid body, screw rod is connected with spring clutch, spring clutch and clamper are connected to become a rigid body, and clamper is connected with another stepper motor, and stepper motor is connected with widely different pivoted arm.

The utility model is owing to adopt the shuttle changing shell to replace changing rotating shuttle; the workman is as long as take out peg or spindle with the bobbin case of changing; on coil winding machine, wind bottom line; reinstalled on the bobbin case frame that bobbin case is placed on the right side just, when the peg or spindle for the treatment of second stature has not had bottom line, this device will repeat above-mentioned action; so not only greatly reduce working strength of workers; and, shortened the time of shutting down the line that refoots, improved the efficient of embroidery work.

The specific embodiment:

Describe the specific embodiment of the present utility model in detail below by accompanying drawing.

The utility model contains two stepper motors, wherein stepper motor 1 is fixed on the support 4, motor shaft and screw rod 2 are connected to become a rigid body, screw rod 2 is connected with spring clutch, spring clutch is made up of spring housing 5, spring 6 and anti-skidding packing ring 7, spring clutch and clamper 8 are connected to become a rigid body, and clamper 8 is connected with stepper motor 9, and stepper motor 9 is connected with widely different pivoted arm 10.

Propelling of the present utility model and widely different rotatory force except adopting stepper motor, also can adopt rotary magnet, pneumatic components and parts, oil cylinder, cylinder and other rotations or plug-type components and parts transmission.

Clutch power of the present utility model except spring, also can adopt components and parts such as electromagnetic clutch and pneumatic clutch to replace.

Operation principle: the utility model is provided with two micro-step motors, wherein motor 1 is connected as a single entity with screw rod 2, when being rotated counterclockwise, it drives screw rod 2 rotations, the bottom and the screw rod 2 of the clamper 8 outside the screw rod 2 are relations of screw and nut, motor 1 rotation, the clamper moving linearly, under the effect of locating piece 12, clamper 8 is pushed ahead moving linearly, in the regular hour, the motor 9 that is contained in clamper 8 tops is rotated counterclockwise, and drives widely different pivoted arm 10 and opens bobbin case and fasten the empty bobbin case that does not have bottom line, at this moment, motor 1 turns clockwise, whole clamper 8 withdraws from, and after bobbin case fell back on certain position, motor 9 turned clockwise and quits work.There is not the bobbin case of bottom line under the gravity effect, freely to fall, after clamper 8 leaves locating piece 12, under the effect of spring 6, clamper 8 is made moving 90 degree of widely different transhipment to the right, motor 1 quits work, this moment, motor 9 was rotated counterclockwise, and fastened the preparation bobbin case that bottom line is housed, at this moment, motor 1 is again counterclockwise to anticlockwise, when clamper 8 was run into limited block 11, clamper 8 entered locating piece 12, continued to the previous crops linear advancement, in certain scope, motor 9 turns clockwise, under the acting in conjunction of two stepper motors, with the bobbin case rotating shuttle of packing into.This moment, motor 9 quit work, and motor 1 turns clockwise again, and clamper 8 withdraws from along straight line, and more than action is the one-period of the line that refoots automatically.Embroidery machine begins to embroider under the instruction of computer.
