Description

Weft insertion mechanism and water jet loom Technical Field The utility model relates to the technical field of textile equipment, in particular to a weft insertion mechanism and a water jet loom. Background The weft insertion mechanism of the water spraying loom in the prior art comprises a water pump, a connecting rod and a cam, wherein the cam is arranged on a wallboard through a cam shaft and rotates along with the cam shaft, the connecting rod is arranged on the wallboard through a connecting rod shaft and can rotate around the connecting rod shaft, one end of the connecting rod is provided with a roller which is in contact fit with the cam, the other end of the connecting rod is connected with a plunger of the water pump through a connecting sheet, and the connecting rod is driven to rotate through the roller when the cam rotates so as to realize the reciprocating motion of the plunger of the water pump, so that the water pump water sucking and water draining processes are completed. In the working process, as the cam drives the connecting rod to rotate through the roller, the outer diameter of the point which is in contact fit with the roller on the cam is changed from large to small and then from small to large, in the process that the outer diameter of the contact point is changed continuously, the radial force of interaction can be generated between the cam and the roller, and the radial force is changed continuously, so that the end parts of the cam shaft and the connecting rod shaft are affected by the radial force to vibrate, and especially the cam shaft for driving the cam to rotate is arranged at the end part of the cam and is at a certain distance from the bearing of the cam shaft, the end part of the cam shaft is affected by the gravity of the cam and the radial force generated between the cam and the roller, so that the vibration generated at the end part of the cam shaft is larger, the service life of the bearing of the cam shaft is affected, the stability of the expansion stroke of the water pump plunger is affected, the stability of the weft insertion procedure of the water jet loom can not be ensured effectively, and the problem that the cloth quality is affected by the weft insertion bad easily occurs. Disclosure of utility model The utility model aims to overcome the problems in the prior art and provide a weft insertion mechanism which can realize stable weft insertion of a water jet loom so as to effectively ensure the quality of cloth cover. In order to achieve the aim, the utility model provides a weft insertion mechanism, which comprises a water pump, a cam and a connecting rod, wherein the cam is arranged on a wallboard of a water jet loom through a cam shaft, and the connecting rod is arranged on the wallboard through a connecting rod shaft; The cam end is arranged at a first end of the cam shaft, which extends out of the cam, through a bearing; the fixed end is fixedly arranged on the wallboard. In an alternative embodiment of the utility model, the stabilizer further comprises a link end fixedly arranged at a first end of the link shaft protruding from the link. In an alternative embodiment of the utility model, the water pump comprises an upper flange hole and an upper bolt, and the upper bolt sequentially penetrates through the fixed end and the upper flange hole to be fixedly connected with the wallboard. In an alternative embodiment of the utility model, the stabilizer comprises a hollow center to expose the link and the roller on the link. In an alternative embodiment of the present utility model, the stabilizer is triangular.
