Problems solved by technology

As a result, the following technical problems are caused: first, it takes up a lot of space in the production site, and also constitutes an interfering influence on passing pedestrians; second, as mentioned above, because the sword belt needs to have the rigidity required by the weft insertion process, it is prone to cracks and even breaks. ; Its three, sword belt service life is short, changes frequently and affects the working efficiency of loom
[0006] The applicant entrusted relevant departments to conduct an in-depth and detailed search of patent and non-patent literature, but there was no enlightenment to fully solve the above technical problems

Embodiment 1

[0025] See figure 1 ,exist figure 1 In the frame 1 of the rapier loom, a first guide rail 11 and a second guide rail 12 are formed on the upper part of the part of the frame 1 facing the weft insertion mechanism, and the first and second guide rails 11 and 12 are parallel to each other. , a rapier edge guide groove 111 is provided on the side of the first guide rail 1 facing the second guide rail 12 and along the length direction of the first guide rail 11, and on the side of the second guide rail 12 facing the first guide rail 11 and along the length direction of the first guide rail 11. A belly belt guide chute 121 is provided in the length direction of the second guide rail 12 , and the area between the first and second guide rails 11 and 12 is formed as a sword belt sliding groove 13 , and the sword belt sliding groove 13 can also be referred to as a belly belt Guide chute. exist figure 1 Also shown in the drawing wheel 2, the rapier 3 and the rapier belt 4 of th...

Embodiment 2

[0033] please see image 3 and Figure 4 and still combine figure 1 , in this embodiment, the aforementioned sword belt engagement portion 51 is changed to a sword belt edge slot that is set in the length direction of the belly belt 5 and faces the sword belt 4 side, and the sword belt 4 faces the length direction of the belly belt 5 The edge part of one side of the sword is inserted into the edge groove of the sword belt and meshed with the edge groove of the sword belt. It can be seen that, in addition to the sword belt matching flange hole exemplified in the first embodiment, the sword belt engaging portion 51 also has two structural forms of the sword belt edge slots exemplified in this embodiment.

[0034] As shown in the figure, the height of the aforementioned sword belt engaging portion 51 is adapted to the thickness of the sword belt 4, so as to ensure that the edge of the sword belt 4 facing the belly belt 5 is properly embedded in the edge slot of the sword...

Abstract

The invention provides a weft insertion mechanism of a rapier loom, and belongs to the technical field of textile machinery. The weft insertion mechanism comprises a weaving machine frame, wherein a first guiding rail and a second guiding rail which are parallel to each other are formed at the upper part of one end of the weaving machine frame; a rapier belt sliding groove is formed between the first guiding rail and the second guiding rail; and the weft insertion mechanism further comprises a rapier guiding wheel, a rapier head and a rapier belt. The weft insertion mechanism is characterized in that the weft insertion mechanism also comprises an abdominal belt and an abdominal belt wheel; one end of the abdominal belt is fixed on the rapier head, the middle part of the abdominal belt is matched with the rapier belt sliding groove, the other end of the abdominal belt is matched with the flange of the abdominal belt wheel, and the end part of the other end of the abdominal belt is fixed on the flange of the abdominal belt wheel; a rapier belt meshing part is also formed in the length direction of the abdominal belt; one side of the rapier belt facing to the abdominal belt is matched with the rapier belt meshing part in the rapier belt sliding groove; the abdominal belt wheel is connected with a rapier guiding wheel driving shaft; and the other end of the rapier belt is fixed on the rapier guiding wheel. The weft insertion mechanism has the advantages as follows: space economization is facilitated; the rapier belt can achieve flexibleness; and in addition, the rigidity of the rapier belt can also be ensured after the rapier belt is combined with the abdominal belt, so that the service life of the rapier belt is prolonged, and the work efficiency of the rapier loom can be ensured.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a weft insertion mechanism of a rapier loom. Background technique [0002] The weft insertion mechanism of the rapier loom can be seen from its literal interpretation that its function is to transport the weft. There is no lack of technical information on the weft insertion mechanism of rapier looms in the published Chinese patent documents, such as: "rapier belt drive mechanism for rapier looms" recommended by authorized announcement number CN1779008B, provided by CN200985409Y "Rapier belt guide mechanism for rapier looms" and "Rapier electronic weft insertion system" introduced by CN201785584U, etc. [0003] Not limited to the patent documents cited above all involve the sword belt and the sword transmission wheel, and the cooperation mode and structure of the sword belt and the sword transmission wheel are the same. Specifically, under the clockwise and...
