Description
Technical field
The present invention relates to a kind of electronics bar tacking machine, particularly a kind of control device of pneumatic outer presser foot pressing mechanism of bar tacking machine.
Background technology
The electronics bar tacking machine is the spe-cial-purpose uniform equipment such as a kind of case and bag, leather, label, is mainly used in their decorating sewing.This machine utilizes direct-driven servo motor to drive upper axle, and X-axis and Y-axis all adopt stepper motor to drive, and programme by programming software or guidance panel, adopts computer control to finish the sewing device of various styles.
External pressure feet lifting and pressing mechanism in the bar tacking machine refers to take electromagnet as power source, by other linkage so that outer presser feet is finished promotes or the mechanism of descending motion.
As shown in Figure 1, in the control device of prior art Pneumatic external pressure feet lifting and pressing mechanism of pattern weaving machine, connecting rod adapter sleeve D13 is by connecting rod shaft D23 and E type back-up ring D14, the left connecting rod D15 of E type back-up ring D19 and stock support, stock support right connecting rod D20 cooperates, stock support connecting rod D17 one end is by stock support pitman shaft D18 and E type back-up ring D16, the left connecting rod D15 of E type back-up ring D21 and stock support, stock support right connecting rod D20 cooperates, the left connecting rod D15 of stock support, stock support right connecting rod D20 uses respectively feeding link pin D12, feeding link pin D22 is connected with stock support D1 with screw D34; Lifting connecting rod adjustment plate D5, lifting connecting rod are adjusted plate D32 and are fixed on left support connecting rod D4, the right support connecting rod D27 with screw D6, screw D31 respectively, and left support connecting rod D4, right support connecting rod D27 cooperate with left lifting arm D9, right lifting arm D25 with lifting connecting rod return spring D8, lifting connecting rod return spring D26 respectively; Left support connecting rod D4, right support connecting rod D27, left lifting arm D9, right lifting arm D25, the left torsion spring D11 of lifting connecting rod, the right torsion spring D24 of lifting connecting rod are installed on the stock support D1 by promoting pitman shaft D28, and the two ends that promote pitman shaft D28 are fixed with packing ring D29, E type back-up ring D30 and back-up ring D3, screw D2 respectively; Left support connecting rod D4, right support connecting rod D27 cooperate with stock support connecting rod D17 by stock support pitman shaft D10 and E type back-up ring D7, E type back-up ring D33; Stock support D1 is installed in other mechanism with screw D35 and packing ring D36.
In use, when electromagnet energising adhesive, utilize other linkage transmission in above-mentioned controlling organization, thereby outer presser feet is promoted; When the electromagnet power-off restoration, utilize the pulling force of return spring in this controlling organization to reset.When large or other linkage moment was larger when the pulling force of return spring, electromagnetic actuation was slow or can not adhesive; When less or other linkage moment was larger when the pulling force of return spring, mechanism resetted and more maybe can not reset, so that the machine cisco unity malfunction, affected the performance of machine.The suction-combining force of electromagnet can't freely be adjusted, so that machine during thick material, presss from both sides not calking material because of the thrust deficiency in sewing, positioning occurs, causes the stitching phenomenon of losing shape.This mechanism element is many, and assembling is complicated, and the casing machining accuracy is high, makes cost higher.
