Description

Weft insertion mechanism of loom Technical Field The invention relates to the technical field of looms, in particular to a weft insertion mechanism of a loom. Background In the prior art, in the aspect of weaving by using the existing loom, weft yarn is usually required to be weft inserted by using a weft insertion device, and the weft yarn is usually placed on a yarn drum frame of the weft insertion device by a yarn drum shape before weft insertion, and is also called as feeding of the weft insertion device, but the yarn drum frame used by the weft insertion device of the traditional loom usually adopts a simpler integral structure, namely, the yarn drum frame lacks good regulation performance, and because the yarn drums of feeding are wound with yarns with different lengths, the condition of different sizes often exists, when the larger yarn drums are fed, if the intervals of the yarn drum frames are different, the larger yarn drums are easy to cause that the larger yarn drums cannot be fed normally, the smaller yarn drums which can be normally placed are often required to be replaced, the operation is more troublesome, the time is easy to spend, the weft insertion operation of the loom is difficult to influence, and the feeding efficiency of the weft insertion device is seriously influenced. In addition, because the rocking of the yarn cylinder wall and the cylindrical rod can lead to further aggravation of abrasion of a cylinder hole of the yarn cylinder, the coaxial rotation matching precision with the cylindrical rod is poorer and stronger, and the abrasion of the cylinder hole is aggravated again, thereby forming a snowball-type unfavorable cycle. In the prior art, in order to reduce the shaking degree of the yarn barrel rotation, the flexible reliability of coaxial rotation is improved, the fit clearance between the barrel hole and the cylindrical rod is set to be smaller, but the mounting of the yarn barrel is very difficult, the yarn barrel mounting efficiency is low, the yarn barrel is unique in model, high in requirement on the dimensional accuracy of the yarn barrel and not universal. Disclosure of Invention The invention provides a weft insertion mechanism of a loom, which aims to solve the problem that a creel frame used by a traditional weft insertion device in the prior art is easy to cause abnormal feeding because the position of the creel frame cannot be conveniently and accurately adjusted. In order to achieve the aim, the weft insertion mechanism of the loom adopts the following technical scheme that the weft insertion mechanism comprises a mounting column, a plurality of columns of yarn cylinder frames are fixedly arranged around the mounting column, one end of each yarn cylinder frame is fixedly connected with an adjusting mechanism for moving the yarn cylinder frame, the adjusting mechanism comprises a shifting tube which is fixedly arranged at one end of the yarn cylinder frame and extends towards the outer side of the mounting column, one side of the shifting tube is axially and slidingly connected with a push disc which is coaxial with the shifting tube, one side of the push disc, which is away from the shifting tube, is rotationally connected with a knob through a rotating rod, one end of the shifting tube, which is away from the push disc, is fixedly connected with a sliding block, one side of the sliding block is internally provided with a clamping block in an axially sliding fit along the shifting tube, one side of the clamping block is exposed out of the sliding block and then clamped into a corresponding clamping groove formed in the side wall of the mounting column, and all the clamping grooves are arranged at the bottom of a rectangular strip groove on the side wall of the mounting column at intervals and are arranged in a straight sliding fit; The adjusting mechanism of the invention also comprises a screw rod which is rotatably arranged in the shifting pipe, a sliding disc is sleeved on the screw rod in a threaded manner, and the sliding disc is fixedly connected with the clamping block through a connecting plate which is simultaneously and slidably arranged in the sliding block and the shifting pipe, so that when the pushing disc is attached to the end part of the shifting pipe, the screw rod can rotate by rotating the knob to drive the clamping block to extend out of or retract into the sliding block, and when the sliding disc moves to be in abutting connection with one end of the shifting pipe, the clamping block is clamped in place in the clamping groove. The end part of the screw rod is rotatably arranged in a first mounting disc fixed in the shifting tube, one end of the shifting tube is sealed through a second mounting disc fixedly connected with the shifting tube, one end of the rotating rod penetrating through the second mounting disc is fixedly connected with a rotating block, and the rotating block can be in plug-in fit with a positioning groove on the end fac
