In addition, the connecting rod rest in the current market has the following problems that a transmission mechanism of one gear group is used for bearing transmission swing: 1. stability is poor: the transmission mechanism of one gear and one group only has one group of transmission mechanisms to bear the swing of the needle core, the groove needle and the guide bar in the transmission process, the load capacity of the transmission mechanisms is large, and the transmission is not stable enough; 2. the corresponding transmission mechanisms of the long-direction pieces are few, the distance between the supporting points is large, the vibration of the long-direction pieces is large, and the quality of fabrics is affected; three easily worn out: under the high-speed operation of the warp knitting machine, the larger the power transmitted by the transmission part is, the larger the inertia of the transmission part is, the abrasion is increased, the matching precision among parts is reduced, the high-speed operation of the equipment is not facilitated, and after the machine operates for a period of time, the equipment is necessary to be maintained and repaired. In severe cases even beyond the expected maintenance time, the transmission components have broken.
Therefore, the invention also comprises an improvement scheme: referring to fig. 4 to 5, the looping mechanisms 2 respectively comprise a connecting rod rest assembly, and the two connecting rod rest assemblies share one crankshaft 7; the connecting rod rest assembly comprises a rest body 8, eccentric connecting rods 3a and 3b, swinging rods 4a and 4b and pull rods 6a and 6b, and a first gear of the connecting rod rest assembly is provided with two groups of transmission mechanisms to form three gears and six groups of transmission mechanisms; the connecting rod rest component is any one of a groove needle transmission mechanism, a needle core transmission mechanism, a loop removing piece transmission mechanism, a sinker transmission mechanism and a guide bar transmission mechanism; the crankshaft 7 includes three pairs of adjacent bell cranks 1a.

The connecting rod bracket assembly comprises more than three pairs of bellcrank, each pair of bellcrank is provided with two adjacent bellcrank, each bellcrank is provided with a group of transmission mechanisms, and one pair of bellcrank corresponds to two transmission mechanisms to form a connecting rod bracket assembly of one gear and two groups of transmission mechanisms. 1. The transmission is more reliable and stable: the two transmission mechanisms in the first gear can be provided with the transmission mechanism with the same width which is doubled, the grooved needle bed, the needle core bed, the loop removing piece, the sinker and other loop forming long-direction pieces are increased in swing arm number, the swing arm distance is reduced, the supporting points of the long-direction pieces are increased, and the long-direction pieces run more stably; 2. the service life of the transmission part of the connecting rod rest is prolonged: the number of the transmission mechanisms is increased, so that the stress of each pair of transmission mechanisms is reduced, and the transmission parts are prevented from being broken due to serious abrasion.
In addition, since the symmetrical double-output wide-width warp knitting machine shares one main shaft 7, if the knitting failure occurs in the knitting mechanism 2 on one side during the working process, the whole warp knitting machine must be stopped, and the normal production quantity on the other side is wasted, in order to solve the problem, the application also proposes an improvement scheme, see fig. 6 to 11, which is as follows: the pull rods 6a, 6b comprise a proximal shaft section 61, a distal shaft section 62 and a linkage sleeve 63; the proximal shaft section 61 and the distal shaft section 62 are respectively sleeved in the linkage sleeve 63 by sliding at two ends of the linkage sleeve 63 and are respectively clamped with the linkage sleeve 63, and the opposite ends of the proximal shaft section 61 and the distal shaft section 62 sleeved in the linkage sleeve 63 are provided with a distance;
