The utility model relates to a knitting machine field, concretely relates to sley bar bed subassembly bilateral drive's tricot machine.
Background
The jacquard warp knitting machine is a warp knitting machine with jacquard device, comprising a looping device, a guide bar device and a transmission device, wherein jacquard needles are driven by the jacquard device to knit, the knitted pattern can be very large, and the shape is not limited. Wherein, the looping device comprises a symmetrical front and back knocking-over part, a symmetrical front and back needle bed part and a symmetrical front and back sinking part; the guide bar device comprises a guide bar bed component and a guide bar seat movably connected with the middle part of the guide bar bed component, the upper end of the guide bar bed component is hung on an upper swing shaft of the frame, a guide bar is arranged on the guide bar bed component, and a guide needle is connected on the guide bar; the transmission device comprises a front needle bed transmission mechanism and a rear needle bed transmission mechanism which correspond to the front needle bed part and the rear needle bed part, a front sedimentation transmission mechanism and a rear sedimentation transmission mechanism which correspond to the front sedimentation part and the rear sedimentation part, an upper swing transmission mechanism of the guide bar bed component and a lower swing transmission mechanism of the guide bar bed component.
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;

However, in the warp knitting machine with the guide bar swinging mechanism arranged on one side for canceling slow swing, when the speed of the main machine reaches 1000 revolutions, firstly, the inertia force of each reciprocating part of the main machine is unbalanced, which brings great influence to the vibration of the machine frame and even leads to the displacement or resonance of the main machine, and meanwhile, under the condition that each part of the machine tool vibrates greatly, the service life of the main machine is obviously shortened, a yarn path is not stable in the knitting process, and the phenomena of missing needles or yarn breakage are easily caused.
