Described triangle base 7 is fixed installation, fixedly mount described dynamic density cylinder body 6 thereon, and at triangle base 7 and 6 installation linear bearings of dynamic density cylinder body, by being installed in the air rammer 28 on the dynamic density cylinder body, carry out along the moving forward and backward of drive link 21 thereby drive part on the dynamic density triangle base 1 be installed on the linear bearing, part that can displacement comprises each part in the driving mechanism.
When density electrical machine 18 work, driving driving cam 22 mounted thereto does together and clockwise rotates, the overhanging protrusion edge 2221 of cam can rotate around the cambered surface 1112 of density electrical machine frame endoporus 1111, the overhanging protrusion edge 2221 of its cam can carry out spacing adjusting by driving cam limited block 226, arc surface 2211 and limited block 10 end faces 1012 of base cam extension are done tangent motion, when driving cam 22 turns to certain position, meeting and the limited block 10 that is installed on the drive block 9 are inconsistent, thereby driving drive block 9 and part mounted thereto moves together, drive link 21 passes to density cam 28 with this rotation, density cam 28 is made accordingly and being rotated counterclockwise, density cam 28 is by the rotation in dynamic density cam block 2 grooves, dynamic density cam block 2 can be pressed down, finish dynamic density cam block 2, dynamic density rise cam 4, dynamic density depressing cam 3 is together to the purpose of bottom offset.In like manner, when density electrical machine 18 drive driving cams 22 rotate counterclockwise, driving cam 22 turn an angle after and limited block 10 inconsistent, can drive drive block 9 and upper-part thereof corresponding the rotation occurs, drive link 21 transmissions are to density cam 28, density cam 28 clockwise rotates, and again with dynamic density cam block 2 jack-up, finishes dynamic density cam block 2, dynamic density rise cam 4, dynamic density depressing cam 3 together to the purpose of top offset.In the course of the work, can limit by the position of 24 pairs of the first straight pins 26 of upper limit holding screw, position by 25 pairs of the second straight pins 27 of lower limit holding screw limits, thereby the upper and lower displacement of finishing dynamic density cam block 2 limits, and when work, can by the cooperation of slide block buffers push rod 19 and slide block buffers spring 20, dynamic density cam block 2 be reduced to initial position.
By being installed in air rammer 28 work on the dynamic density cylinder body, carry out along the moving forward and backward of drive link 21 thereby drive part on the dynamic density triangle base 1 that is installed on the linear bearing, part that can displacement comprises each part in the driving mechanism.And in this course of work, triangle base 7 and dynamic density cylinder 6 keep motionless, thereby realize working position subluxation and full position, and can carry out the early warning protective effect by subluxation spacing alarm mechanism 12 and full position induction mechanism 13, the specific works mode is as follows: according to the type that do not suit, under programme-control, when described density transmission mechanism is in original position, induction pin 1214 contacts with induction planes 1224 on the dynamic density triangle base 1, does not report to the police at this moment; When by air rammer 29 the syringe cambered surface on the dynamic density triangle base 1 being pushed to subluxation, this moment, the density transmission mechanism was subjected to displacement thereupon, thereby can allow the induction planes 1224 of responding on pin 1214 and the dynamic density triangle base 1 be in released state, this is normal operating conditions, does not report to the police; If dynamic density triangle base 1 does not enter subluxation, the density transmission mechanism is not subjected to displacement, and the induction planes 1224 that respond on pin 1214 and the dynamic density triangle base 1 this moment still is in contact condition, and be abnormality this moment, and alarm appears in inductor.When air rammer 29 is pushed to full position with dynamic density triangle base 1, high pin knitting needle and low pin knitting needle enter to simultaneously in the Cam Track that the density transmission mechanism forms and carry out work, the inductor pin 133 of alarm mechanism is in fit-state with the front end face 161 of dynamic density triangle base 1 at this moment, and do not report to the police this moment; When air rammer 29 is not pushed to dynamic density triangle base 1 full position, inductor pin 133 will be in released state with the front end face 161 of dynamic density triangle base 1, and the inductor 134 that is connected in 132 on induction hex nut 131 and inductor nut this moment will carry out induction alarm.And full position, the subluxation of subluxation-full position position-limit mechanism 14 and 17 pairs of dynamic density transmission mechanisms of full position position-limit mechanism can limit and regulate.The stop screw 141 of subluxation-full position position-limit mechanism 14 is adjusted to certain position, just can requires rapid, sensitive complete and the subluxation of entering according to program.And after the dynamic density triangle base is promoted to enter full position, subluxation work by air rammer, reset by the spring 144 in the spring housing 145, spacing by stop screw 141.And by regulating the holding screw 172 of full position position-limit mechanism 17, thereby limit the distance of holding screw 171 front end face 71 to the triangle base 7, thus carry out spacing.And half position-limit mechanism 15 between dynamic density cylinder body 6 and power degree triangle base 1 also can by the adjusting of bolt, play the effect that limits subluxation.
Move up and down to make knitting needle to move up and down to change coil size along the track that dynamic density depressing cam, dynamic density rise cam form by the density transmission mechanism along syringe circumference cambered surface, thereby change Density.By two kinds of limiting structures are set, can effectively guarantee the displacement of density transmission mechanism when moving up and down, increased substantially Density quality of regulation and stability.The present invention can precisely regulate Density, and compact simple on structural design, and the Auto-regulating System of Density of Heavy Medium of the type that is adapted to not suit is convenient to installation and maintenance, in various degree saved cost to the user.
