Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an air jet loom which is convenient for position limiting. Background Art

[0002] Weaving is an ancient and important textile process that makes various fabrics by interweaving warp and weft threads. In the weaving process, the warp is the thread perpendicular to the ground, while the weft is the thread horizontal to the ground. These two threads are interwoven to form the basic structure of the fabric. When weaving, an air jet loom is needed. Air jet loom is a common weaving equipment widely used in the textile industry. The air jet loom generates high-speed airflow through the nozzle, blowing the weft from one position to another, forming a reciprocating motion, so as to complete the interweaving of the weft and the warp. When the airflow passes through the gaps in the fabric, it drives the weft to shuttle, so that the warp and weft are intertwined with each other, and finally form a cloth.

[0003] However, the existing air-jet loom has the following disadvantages: when the air-jet loom is winding the cloth, a tensioning roller is required to tension the cloth. Since the length of the tensioning roller is fixed, it is not convenient to limit the tension of cloth of different widths, which causes the cloth to easily deviate when winding. Therefore, the existing air-jet loom needs to be improved. Utility Model Content

[0026] according to Figure 2 , Figure 3 and Figure 6 As shown, the limiting mechanism 5 includes a limiting pin 501, a push rod 502, a positioning groove 503, a No. 1 return spring 504, a limiting block 505, a No. 2 return spring 506 and a limiting hole 507. The two sides of the tensioning roller 11 are provided with spaced limiting holes 507, and the limiting holes 507 are provided with limiting pins 501 inside, and the limiting pins 501 pass through the two sides of the limiting ring 7. The outer side of the limiting pin 501 is sleeved with the No. 1 return spring 504. A No. 2 return spring 506 is provided in the built-in groove on one side of the positioning pin 501, and a limit block 505 is provided on one side of the No. 2 return spring 506, and the limit block 505 is slidably connected to the limit pin 501. A positioning groove 503 is opened inside the limiting ring 7 near the limit pin 501, and a push rod 502 is slidably connected inside the positioning groove 503, and one end of the push rod 502 is located on the outside of the positioning groove 503, and the cross-sectional shape of the push rod 502 is "L"-shaped.

[0027] The first return spring 504 rebounds and drives the limit pin 501 to engage with the limit hole 507, thereby limiting the position of the limit ring 7. The tensioning area of ​​the tensioning roller 11 can be quickly adjusted to meet the tensioning requirements of cloth of different widths, limit the position of the cloth, prevent the cloth from shifting, and improve the working quality of the air-jet loom.

[0028] according to Figure 3-4 As shown, the pressing mechanism 9 includes a fixed block 901, a connecting rod 902, a limit spring 903 and a pressure plate 904. A fixed block 901 is fixed on one side of the limit ring 7. A connecting rod 902 slides through the inside of the fixed block 901. The outer side of the connecting rod 902 is sleeved with a limit spring 903. The end of the connecting rod 902 close to the tensioning roller 11 is connected to a pressure plate 904, and the cross-sectional shape of the pressure plate 904 is an arc.

[0029] In specific implementation, while the tensioning roller 11 is tensioning and limiting the cloth, the limit spring 903 rebounds and drives the connecting rod 902 to push the pressure plate 904 to one side, so that the pressure plate 904 rests on the cloth, limiting the cloth again, and improving the tensioning quality of the tensioning roller 11.

[0030] according to Figure 1-2 , Figure 5 and Figure 7 As shown, the cleaning mechanism 12 includes a U-shaped frame 121, a slide rod 122, a No. 3 return spring 123 and a connecting frame 124.

The outer side of the slide rod 122 is sleeved with a No. 3 return spring 123 and a connecting frame 124. One side of the connecting frame 124 is connected to the cleaning roller 13 through a bearing.

[0031] During specific implementation, since a lot of fluff or dust is easily generated on the upper surface of the fabric, when the receiving roller 6 is winding the fabric, the fabric can contact the cleaning roller 13, so that the receiving roller 6 and the cleaning roller 13 rotate in opposite directions, and the cleaning roller 13 adheres to the fluff or dust on the surface of the fabric. When the fabric is wound thicker and thicker, the fabric squeezes the cleaning roller 13, so that the cleaning roller 13 drives the connecting frame 124 to slide upward on the slide rod 122 and squeeze the No. 3 return spring 123. The No. 3 return spring 123 rebounds and drives the connecting frame 124 to move downward, so that the cleaning roller 13 contacts the surface of the fabric, which is conducive to quickly cleaning the surface of the fabric and improves the practicability of the jet loom.

[0032] Working principle: When using this kind of air-jet loom that is easy to limit, first, the textile frame 2 and the weft insertion mechanism 3 cooperate with each other. The weft insertion mechanism 3 sprays air from the nozzle through the air source, sends the weft thread from one side to the other side, and interweaves the warp thread to complete the weaving process. The cloth is limited and tensioned by the limiting mechanism 5 and the pressing mechanism 9 to prevent the material from being offset. The woven cloth is pulled out from the tensioning roller 11, and then pulled out from the contact point between the cleaning roller 13 and the receiving roller 6, and the woven cloth is pulled onto the receiving roller 6 for winding. At the same time, the cleaning roller 13 and the cleaning mechanism 12 clean the woven cloth, which improves the working quality and practicality of the air-jet loom. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.
