As shown in fig. 1, the combined guide bar bed comprises a guide bar bed assembly 1 ', an upper swing mechanism 2' and a lower swing mechanism 3 ', wherein the lower swing mechanism 3' is a high-speed swing, the guide bar bed assembly 1 'is driven to rotate around a lower swing shaft 11', the lower swing shaft is controlled by a lower swing link 31 'of the lower swing mechanism 3' to move, and an end portion 32 'of the lower swing link 31' is hinged to the guide bar bed assembly 1 ', in such a structure, the swing amplitude of the guide bar bed assembly 1' is large, and particularly, two guide bars close to the outer side often influence the quality of produced products due to the excessively large swing amplitude;

in order to avoid or reduce the above-mentioned situation, the upper swing mechanism 3 'is set as a low speed swing to drive the whole guide bar bed assembly 1' to rotate around the upper swing shaft 21 'so as to compensate the swing amplitude of the guide bar bed assembly 1'.

Under the structure, the whole structure of the device is complex, the upper swing mechanism 2 'and the lower swing mechanism 3' need to be adjusted to be matched with each other when the swing of the guide bar bed component is adjusted, and the adjustment is inconvenient.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model provides a sley bar bed subassembly swing mechanism has solved the comparatively inconvenient problem of sley bar bed subassembly adjustment.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

the utility model provides a sley bar bed subassembly swing mechanism, includes the frame, but the pivot axle that the level of rotatable ground erects in the frame set up, pivot axle fixed mounting has a swing arm, the swing arm with pivot rigid connection, a pendulum rod is connected to the free end of swing arm, the pendulum rod is connected with the transmission of tricot machine, sley bar bed subassembly is through a connecting rod fixed mounting in the pivot axle below, the both ends of connecting rod respectively with pivot axle, sley bar bed subassembly rigid connection, the connecting rod with the coincidence of the axisymmetric center of sley bar bed subassembly.

Preferably, one end of the swing arm connected with the swing rod is provided with a plurality of installation adjusting holes, and the swing rod is installed on one installation adjusting hole.

Preferably, one end of the swing arm connected with the swing shaft is an arc mounting groove, the arc mounting groove is fixedly mounted with the swing shaft through a fixing block, and the circle center of the arc mounting groove and each mounting adjusting hole are arranged on the same axis.

By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses a change the principle at sley bar bed rotation center, saved lower swing mechanism on original basis, shift up the swing center of sley bar bed subassembly simultaneously, the swing radius increase in sley bar bed motion process, the swing range of sley bar bed lower extreme reduces, the wobbling range has been reduced, not only structurally retrench to some extent, also guarantee the good operation of equipment, especially to the sley bar in the sley bar bed both ends outside, the phenomenon appearance that influences the product quality such as yarn skipping appears in the guide needle that can be very big avoid it on it.
