Abstract
The utility model discloses an embroidery machine head, which comprises a head frame and a presser foot lifting block. The presser foot lifting block is mounted inside the head frame and drives a needle rod to reset. As improvement, the embroidery machine head further comprises a positioning switch, an electromagnetic induction driver and a programmable control chip, the positioning switch matches with the needle rod, the mutually matching electromagnetic induction driver is disposed on the presser foot lifting block and the head frame, and the programmable control chip receives signals of the positioning switch to control action of the electromagnetic induction driver. The programmable control chip is adopted to control all actions of an electromagnetic switch, a complicated mechanical structure inside a conventional head frame is replaced, a cam and plane connecting rod device is omitted, and the embroidery machine head simplifies a mechanism, and is stable and reliable in running and high in running precision.
Description
Technical field
The utility model relates to a kind of parts of embroidery machine head.
Background technology
In the work of embroidery machine head, the reciprocating motion that needs shank to make down pin, reset, it is pin dependence driver down, resets to rely on the back-moving spring on the shank to reset.Along with the rotating speed of embroidery machine is more and more faster, when meeting or exceeding 800 rev/mins, be far smaller than the reaction time of back-moving spring the resetting time of shank, back-moving spring always has little time reaction, usually needs to increase presser foot lifter for this reason and comes the spring-assisted reduction presser feet that resets.Press the pressure foot lifting piece of angle lifter to do the intermittent reciprocating motion by the cam mechanism that is arranged in the head.The pressure foot lifting piece is along with pin under the shank; do to reset after of short duration intermittence, in the transients that after intermittence, resets, the stressed maximum of cam; it also is the weakest link of cam edge thickness; because the technology of domestic manufacturing cam and the restriction of cam material, when embroidery machine speed further improves or work for a long time, the cam easy deformation makes the track inaccuracy; have influence on resetting of shank; perhaps cam directly damages, and breaks down shutdown maintenance.The cam drive structure has seriously reduced the efficient of embroidery machine, and the further raising of restriction embroidery machine speed is had relatively high expectations to working environment simultaneously.
Summary of the invention
The utility model is for solving prior art in use, and the head cam of existence damages easily, influences the operation operating efficiency of equipment, and a kind of energy high speed operation is provided, and the head framework internal structure and the embroidery machine head stably that turns round are simplified in stable performance.
The technical scheme that the utility model solves existing issue is: a kind of embroidery machine head, comprise the head framework, be installed on and drive the pressure foot lifting piece that shank resets in the head framework, improve as the utility model, also comprise the travel switch that cooperates with shank, be arranged at the electromagnetic induction driver that cooperatively interacts on pressure foot lifting piece and the head framework, receive travel switch signal controlling electrical equipment and respond to the programmable control chip that driver moves.
Improve as the utility model, described travel switch is the solenoid travel switch.
Improve as the utility model, interactional two induction end of described solenoid travel switch are installed on respectively on shank, the needle bar frame.
Improve as the utility model, the two ends of the effect of matching of described electromagnetic induction driver are installed on the corresponding position of pressure foot lifting piece on pressure foot lifting piece and the head framework respectively.
Improve as the utility model, described programmable control chip is fixed in the head framework.
The utility model compared with prior art, its beneficial effect is to finish exercises by programmable control chip control electromagnetic switch, replaced the interior complex mechanical construction of head framework in the past, cam and planar linkage device have been saved, simplified mechanism, it is reliable to operate steadily, the running precision height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the implementation case comprises: head framework 1, be installed on the pressure foot lifting piece 3, the travel switch 4 that cooperates with shank 2 that drive shank 2 in the head framework 1 and reset, be arranged at the electromagnetic induction driver 5 that cooperatively interacts on pressure foot lifting piece 3 and the head framework 1, receive travel switch signal controlling electrical equipment and respond to the programmable control chip 6 that driver 5 moves.
The implementation case is as optimization, and travel switch is a solenoid travel switch 4.Interactional two induction end (41,42) of solenoid travel switch 4 are installed on respectively on shank 2, the needle bar frame 21.The two ends (51,52) of the effect of matching of electromagnetic induction driver 5 are installed on the corresponding position of pressure foot lifting piece 3 on pressure foot lifting piece 3 and the head framework 1 respectively.
In order to keep the reliable and stable operation of embroidery machine, programmable control chip 5 is fixed in the head framework 1.
In the concrete use of the utility model, can be according to the following needle speed and the action request of concrete shank 2, programming Control chip 6 makes control chip 6 drive 3 auxiliary shanks 2 actions of presser feet lift blocks.
