The purpose of this utility model is a kind of card protection mechanism of design, in case this mechanism can guarantee that the card generation is crooked, when causing fault, can stop immediately, reaches the purpose of protecting card and not going out float.
The purpose of this utility model is to realize like this.Select a perpendicular pin, preferably be positioned at the perpendicular pin of marginal portion,, make the hook direction of all common perpendicular pins of hook and other of its upper end opposite, promptly be not suspended from and griffe as the perpendicular pin of protection; The lower end of the perpendicular pin of described protection links to each other with shutdown switch, with the pairing card of the eedles position of the perpendicular pin pairing of described protection is all rolling special-purpose eyelet is arranged, and this eyelet is with different for the function of producing the rolling eyelet of different figured texture weaves, and size then.Like this, in, the normal operation process that do not kink not crooked at card, the cephalic par of the eedles that matches mutually with the perpendicular pin of described protection can both enter in the corresponding special-purpose eyelet on the card at every turn, the plush copper of eedles is to protecting perpendicular pin inoperative, when griffing to rise, the perpendicular pin of protection can not be raised mutually on the contrary because of its upper end hook direction; In case it is crooked or kink that card takes place; special-purpose eyelet on the card is offset; at this moment on-stream erecting with protection can not enter special-purpose eyelet at the eedles cephalic par of answering; at this moment under the effect of described eedles plush copper; the perpendicular pin of protection moves right and the hook of its upper end be suspended from griffe on, when griffing to rise, will protect and erect pin and mention; the shutdown switch that is attached thereto is pulled, and realizes stopping.
This card protection mechanism is simple in structure, reliable; as long as the card position is wrong; special-purpose eyelet on the card departs from; institute corresponding eedles end can not enter; pin is erected in the protection that can promote to match; make this perpendicular pin be griffed to mention, the pulling shutdown switch realize to stop, and what prevented card kinks, damages and produce float.
Accompanying drawing 1 for the eedles of former jacquard attachment, perpendicular pin, the schematic diagram that connects each other of parts such as griffe, accompanying drawing 2 erects eedles on the card protection mechanism of pin for the utility model design protection, erect pin, the schematic diagram that connects each other of parts such as griffe.Among the figure:
1. common eedles; 2. griffe; 3. common perpendicular pin; 4. pin is erected in protection; 5. first line;
6. harness cord; 7. shutdown switch; 8. erect the eedles of pin pairing with protection;
9. eedles plush copper.
Below in conjunction with accompanying drawing the utility model is explained.There are not the eedles of the former jacquard attachment of card protective device, perpendicular pin, connecting each other of griffing to see Fig. 1; eedles 1 level is installed; eedles plush copper 9 contacts with perpendicular pin 3; perpendicular pin 3 is vertically installed; the upper end hook of all perpendicular pins 3 is suspended from equidirectionally griffes 2 top; the lower end hook portion of perpendicular pin 3 hangs with first line 5, and first line 5 links to each other with harness cord 6, and harness cord 6 lower ends connect heald.The relevant modular construction relation of the card protection mechanism that the perpendicular pin of protection is arranged of the utility model design is seen Fig. 2; because when producing different figured texture weave; it is unnecessary that the perpendicular pin of required eedles that works and pairing thereof all has; so a perpendicular pin selecting the edge is as the perpendicular pin 4 of protection; the upper end of the perpendicular pin 4 of protection is reverse hook structures (shown among Fig. 2 4); be that hook is not suspended from and griffes 2 top; its bottom then links to each other with caused by loom stop switch 7 by first line 5; with rolling special-purpose eyelet on the eedles 8 pairing card positions of protecting perpendicular pin 4 pairings, all rolling this special-purpose eyelet on the same correspondence position of each sheet card.Therefore, as long as the card not off normal that works well, the head end of eedles 8 always can pass the cylindrical fireworks hole and enter in the special-purpose eyelet of card, and eedles 8 does not promote to protect perpendicular pin 4 yet, griffes 2 lifter motion to protecting perpendicular pin 4 inoperative.Under the card running off normal situation; the end of eedles 8 can not enter special-purpose eyelet; the plush copper 9 of eedles 8 will promote to protect perpendicular pin 4; the upper end hook of the perpendicular pin 4 of protection is displaced to griffe 2 top; when griffing 2 liftings, drive the perpendicular pin 4 of protection and rise chain pulling caused by loom stop switch; realize shutting down, prevented that card from damaging and producing float.
