Description

Weft laying trolley with self-locking function Technical Field The utility model belongs to the technical field of warp knitting machines, and particularly relates to a weft laying trolley with a self-locking function. Background The weft laying mechanism of the warp knitting machine generally comprises a weft laying trolley, and the yarn laying is realized through the longitudinal and transverse movement of the weft laying trolley. The Chinese patent with the publication number of CN111648022A discloses a weft paving mechanism and a weft paving method of a lapping machine, the weft paving mechanism comprises a weft paving trolley which is arranged in a sliding manner, yarn guide plates of the weft paving trolley are arranged on the weft paving trolley, a plurality of yarn guide holes which are arranged at intervals are formed in the yarn guide plates, yarns can pass through the yarn guide holes, however, the yarn guide plates do not have a self-locking function, when the yarns are continuously laid, the weft paving trolley can retract when reaching a needle block and driving the yarns to transversely move around the needle block, so that the yarns can not be kept in a tight state, and the weft paving effect is affected. Disclosure of utility model The technical problem to be solved by the utility model is to solve the problems that a yarn guide plate of a weft laying trolley does not have a self-locking function in the prior art, and the weft laying trolley can retract synchronously when the yarn reaches a needle block and drives the yarn to transversely move around the needle block, so that the yarn cannot be kept in a tight state, and the weft laying effect is affected. The technical scheme adopted by the utility model for solving the technical problems is that the weft laying trolley with the self-locking function comprises: The yarn dividing assembly comprises at least one reed body with reed eyes, clamping plates with clamping eyes and a transverse moving driving mechanism for pushing the clamping plates to reciprocate so as to align or stagger the reed eyes with the clamping eyes, wherein the reed eyes and the clamping eyes are in one-to-one correspondence; And the yarn pressing assembly comprises a yarn pressing plate and a longitudinal movement driving mechanism for driving the yarn pressing plate to lift. Further, the reed body upper cover is provided with a cover plate, and the cover plate and the reed body are enclosed to form an installation cavity for installing the clamping plate. Further, the number of the yarn dividing assemblies is two, the yarn dividing assemblies are divided into an upper yarn dividing assembly and a lower yarn dividing assembly, and at least one yarn guiding mechanism for guiding yarns is arranged between the upper yarn dividing assembly and the lower yarn dividing assembly.
