The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
See also Fig. 1, mechanism of the present invention is by guided plate 1, backplate 2, support plate 3, control lever 4, lower link I, and upper connecting rod II and extension spring 5 are formed.Wherein backplate 2 is installed in the cabinet 15 of flat braiding machine 13 downsides, and backplate 2 places the front side of lifting bar 8, but and be positioned at the position of slide hinge seat 10 crimping, can be referring to Fig. 2 or Fig. 3.The lower end of the upper end of backplate 2 and guided plate 1 is hinged, and guided plate can be rotated around its hinge axes, and the about 60 ° tilting position of its slewing area bootstrap plate 1 and horizontal sextant angle is to vertical position.Guided plate 1 is made up of framework 6 and panel 7, and panel 7 is connected a side of framework 6 by screw, and the left and right sides of framework 6 is 90 ° of bendings, panel 7 lower ends downward bendings.The symmetrical respectively A point that is hinged on the middle part, two sides of backplate 2 of two support plates 3, the symmetrical respectively bottom that is hinged on the backplate two sides of two control levers 4.Two lower link I symmetry respectively are connected D point place on the homonymy control lever 4 and the C point place on the support plate 3, and two upper connecting rod II symmetry respectively are connected the B point place on the homonymy support plate 3 and the E point place of framework 6 bending sections.Two extension springs 5, the one end is connected with the D point at a side control lever 4 middle parts, and its other end is connected with corresponding position with side guard plate 2.
Please contrast Fig. 2 again, when the braiding beginning, at first play needle knitting, synchronous pulley driving mechanism is started working, two synchronizing wheels 11 rotate counterclockwise, and are with 12 transmissions thereupon synchronously, and a side that is connected with slide hinge seat 10 is with synchronously and is made to go up shifting movement, thereby make with slide hinge seat 10 along moving on the slide rail 14, the lifting bar 8 that is attached thereto with on move.When moving on slide hinge seat 10 begins, control lever 4 is done under the effect of extension spring 5 and is clockwise rotated, and lower link I then promotes support plate 3 and does and clockwise rotate, and support plate 3 promotes guided plate 1 by upper connecting rod II and clockwise rotates.When slide hinge seat 10 was thrown off crimping to control lever 4 fully, upper connecting rod II promoted guided plate 1 and turns to vertical position under the effect of extension spring 5.Extension spring 5 produces thrust F1 upwards by lower link I to support plate 3, and the relative support plate pin joint of this power A produces a clockwise moment M1, and moment M1 makes guided plate 1 make clockwise direction and rotates.At this moment, drop on the line that above-mentioned E point and A order as the tie point B of upper connecting rod II and support plate 3, the thrust F2 that upper connecting rod II produces is because of passing through support plate pin joint A, and the rotating torque M2=0 that relative A is ordered is so guided plate 1 can only clockwise rotate under the effect of moment M1.Drop on the right side (promptly with the relative BE line of tie point C of lower link I and support plate 3 not in the same side) of above-mentioned E point and A point line as the upper connecting rod II and the tie point B of support plate 3, the rotating torque that the relative A of thrust F2 that pull bar II produces is ordered be M2 and moment M1 in the same way, guided plate 1 is clockwise rotated, but guided plate 1 clockwise rotating when vertical position is subjected to the spacing of panel 7 lower end bending parts, can not rotate and makes guided plate 1 be in self-locking state.When guided plate is subjected to the effect of external force G, the thrust F2 that upper connecting rod II is produced is bigger, and consequent moment M2 then strengthens thereupon, and guided plate 1 is in darker self-locking state, thereby makes the state of guided plate 1 when vertical position very stable.
Please contrast Fig. 3, after a needle knitting was finished, synchronous pulley driving mechanism was started working again.Two synchronizing wheels 11 clockwise rotate, be with 12 to drive slide hinge seat 10 downward shifting movements synchronously, when slide hinge seat 10 moves down when being crimped onto control lever 4, the pulling force that overcomes extension spring 5 rotates counterclockwise control lever 4, lower link I then spurs support plate 3 and does and rotate counterclockwise, and support plate 3 rotates counterclockwise by upper connecting rod II pulling guided plate 1.When slide hinge seat 10 moved down into lower position-arresting and puts, guided plate 1 turned to the tilting position about 60 ° with horizontal direction, prepared the braided fabric of continuous whereabouts is played downward guiding function.
