The lopping campaign of compound needle machine generally comprises groove pin motion, movement of slide, knocking over needle movement and sinker motion; Groove pin motion and movement of slide again by the groove pin nook closing member move up and down and swing is composited, in warp knitting machine, the groove pin nook closing member move up and down and oscillating motion is finished by corresponding groove pin nook closing member up-down mechanism and swing mechanism respectively.In the lopping motion, the swing mechanism of groove pin nook closing member is particularly important.
In warp knitting machines such as existing many comb La Sheer, the swing mechanism of groove pin nook closing member comprises main shaft, be installed in eccentric wheel, fuel tank take-off lever on the described main shaft, be arranged on multistage linkage, top link, lopping arm shaft, leading arm and connecting rod rack more than plane six connecting rods between described eccentric wheel and the fuel tank take-off lever; One end of top link is fixedlyed connected with described lopping arm shaft, and the upper end of the other end and described fuel tank take-off lever is rotationally connected; One end of leading arm is fixedlyed connected with described lopping arm shaft, and the other end is slidingly connected with the groove pin bed that described groove pin is installed; Nook closing member bed and described groove pin bed that nook closing member is installed are slidingly connected, and main shaft is installed in the warp knitting machine fuel tank rotationally.In the warp knitting machine of this structure, owing to be multistage linkage more than six connecting rods of plane what adopt between eccentric wheel and the fuel tank take-off lever, as the plane eight-bar linkage, therefore, the complex structure of this swing mechanism, drive path is long, poor reliability, running speed and operating efficiency are lower.In addition, when swing mechanism does not adopt eccentric wheel and adopts inside and outside round conjugate cam, thereby when forming the cam link combined mechanism that conjugate cam and the multistage linkage in plane be in series, its structure is not only more complicated, manufacture difficulty is bigger, and running speed and operating efficiency are lower.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and drive path is short, good reliability, a kind of warp knitting machine groove pin nook closing member swing mechanism of running speed and high efficiency.
For solving the problems of the technologies described above, the utility model adopts so a kind of warp knitting machine groove pin nook closing member swing mechanism, and it comprises the main shaft that is installed in rotationally in the warp knitting machine fuel tank, is installed in eccentric wheel, fuel tank take-off lever, top link, lopping arm shaft, leading arm and connecting rod rack on the described main shaft; One end of described top link is fixedlyed connected with described lopping arm shaft, and the upper end of the other end and described fuel tank take-off lever is rotationally connected; One end of described leading arm is fixedlyed connected with described lopping arm shaft, and the other end is slidingly connected with the groove pin bed that described groove pin is installed; Nook closing member bed and described groove pin bed that described nook closing member is installed are slidingly connected, one connecting rod and following swing arm are set between described eccentric wheel and fuel tank take-off lever, the lower end of described connecting rod is sleeved on the described eccentric wheel, one end of described down swing arm and the lower end of fuel tank take-off lever are rotationally connected with the upper end of described connecting rod respectively, and the described other end and the described connecting rod rack of swing arm down are rotationally connected.
After adopting such structure, owing to a connecting rod and following swing arm only are set between eccentric wheel and fuel tank take-off lever, when work, realize both swings for groove pin and nook closing member the transmission of power of main shaft output by this structure, therefore, this groove pin nook closing member swing mechanism compared with prior art structure is simplified greatly, has shortened drive path, has guaranteed the reliability of transmission, saved a large amount of spaces, in addition, owing to reduced the oscillating motion time, running speed and operating efficiency have therefore been improved.
As a kind of improvement of the present utility model, between described connecting rod and eccentric wheel, also be provided with bearing, the lower end of described connecting rod is contained on the described eccentric wheel by this bearing holder (housing, cover).After adopting such structure, can reduce connecting rod and the eccentric wheel frictional force when rotating, and it is more flexible that connecting rod is rotated, and prolongs its service life.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model warp knitting machine groove pin nook closing member swing mechanism.
Fig. 2 is the structure diagram of swing mechanism shown in Figure 1.
The specific embodiment
A kind of warp knitting machine groove pin nook closing member swing mechanism referring to shown in Fig. 1,2 comprises main shaft 1, is fixedly mounted in eccentric wheel 2, fuel tank take-off lever 3, top link 4, lopping arm shaft 5, leading arm 6 and connecting rod rack on the described main shaft 1; One end of described top link 4 is fixedlyed connected with described lopping arm shaft 5, and the upper end of the other end and described fuel tank take-off lever 3 is rotationally connected; One end of described leading arm 6 is fixedlyed connected with described lopping arm shaft 5, and the other end is slidingly connected by first guide pillar 12 and the groove pin bed 7 that described groove pin 7-1 is installed; The nook closing member bed 8 that described nook closing member 8-1 is installed is slidingly connected with described groove pin bed 7 by second guide pillar 13, knocking over pin 14 is installed on the described leading arm 6 by the knocking over needle-bar, main shaft 1 is installed in the warp knitting machine fuel tank rotationally, described lopping arm shaft 5 is installed on the lopping spindle drum on warp knitting machine fuel tank top rotationally, between described eccentric wheel 2 and fuel tank take-off lever 3, be provided with connecting rod 9 and following swing arm 10, the lower end of described connecting rod 9 is provided with a through hole, connecting rod 9 is sleeved on the described eccentric wheel 2 by this through hole, one end of described down swing arm 10 and the lower end of fuel tank take-off lever 3 are rotationally connected with the upper end of described connecting rod 9 respectively, and the described other end and the described connecting rod rack of swing arm 10 down are rotationally connected.
