Description
Technical field
The present invention relates to the Sewing machines equipment technical field, be specifically related to the resetting means of double needle machine displacement shank.
Background technology
The double needle machine of existing variable bit shank all includes a reset assembly, is used for the angle at the end bent angle and makes.Its structure is: comprise switch assembly, depression bar plate, depression bar, installing rack, spring and column; The switch assembly is installed on the head of sewing machine, and switch assembly one end is provided with column, and the other end is connected through guide rail with the sliding axle assembly; Shank assembly and installing rack are separately fixed on the head of sewing machine; Depression bar one end is connected with installing rack and can does relative slip, and the other end is connected with the depression bar plate through spring, and spring is in compressive state.The problem that existing structure exists is: difficulty is big when the angle bent angle is made, and is difficult for grasping.This be because: pull the switch assembly through hand, the fixing pin number that will make is operated through pedal in the back, lifts presser feet then, rotates sewing, continues to make the pin number that equates with it, press the down-pressed pole plate at last, finishes displacement, accomplishes the angle turning and makes.What difficulty was maximum during this time is exactly the control of pin number, even the skilled worker also often makes mistakes, the operative employee who has just comes accurate pin number through the hand rotary driving wheel, and sewing speed is slow, wastes time and energy.
Summary of the invention
The present invention will provide a kind of resetting means of double needle machine displacement shank, turns in angle and makes the big problem of difficulty to overcome double needle machine that prior art exists.
For overcoming the problem that prior art exists, technical scheme of the present invention is:
The resetting means of double needle machine displacement shank; Comprise reset assembly; Reset assembly comprises switch assembly, depression bar plate, depression bar, installing rack, spring and column, and its special character is: also comprise automatic control unit, said automatic control unit comprises first checkout gear, electromagnet assembly, sliding axle assembly; Said electromagnet assembly is fixed on the installing rack and can promotes depression bar and slides backward, and first checkout gear is fixed on the sliding axle assembly.
Also comprise second checkout gear and compressor arm in the above-mentioned automatic control unit, second checkout gear is fixed on the compressor arm.
Above-mentioned depression bar is installed metallic pin or baffle plate at the end near installing rack.
Above-mentioned depression bar is the bending structure at the end near installing rack.
Compared with prior art, advantage of the present invention is:
1. employing automatic reset mechanism, displacement pin number is predeterminable, accomplishes bent angle automatically and makes;
2. substitute the operation that needs hand, pin to accomplish with electromagnet, save time, raise the efficiency;
3. because making of bent angle is that machinery is automatically accomplished, therefore improved in the prior art speed of making bent angle with manually-operated greatly.
