[0004] The purpose of this invention is to address the above-mentioned problems by providing a yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric includes a base, on which a rotating seat driven by a first rotating drive component is provided. The rotating seat is provided with two yarn bobbin fixing components for installing yarn bobbins of different colors of polyester yarn. Each yarn bobbin fixing component includes a fixing seat, on which an adjustable outer diameter yarn bobbin fixing structure is provided. The fixing seat is also provided with a bobbin unwinding component.

[0007] In the aforementioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the yarn bobbin fixing structure includes a guide shaft with a circular cross-section and two arc-shaped sleeve plates symmetrically arranged on both sides of the guide shaft. The two arc-shaped sleeve plates are combined to form the central sleeve of the yarn bobbin. The guide shaft is fixed on a fixed base. The guide shaft is hollow and has a lead screw with reverse threads at both ends at its center. The fixed base is equipped with a second rotating component connected to the lead screw. A sliding sleeve is screwed to each end of the lead screw. Two guide grooves corresponding to the arc-shaped sleeve plates are also provided through the side wall of the guide shaft. Two connecting rods are hinged to each sliding sleeve. The two connecting rods on the sliding sleeve pass through the two guide grooves and are rotatably connected to the two arc-shaped sleeve plates respectively through an adapter.

[0008] In the above-mentioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the two sides of the connecting rod slide in cooperation with the inner wall of the guide groove.

[0009] In the above-mentioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the first rotary drive component includes a first motor, which is connected to a first rotating shaft set on the base through a reducer, and the rotating seat is fixed on the first rotating shaft.

[0010] In the above-mentioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the second rotating component includes a second motor fixed on a fixed base, and the second motor is connected to the lead screw.

[0011] In the above-mentioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the bobbin unwinding assembly includes an annular push plate concentrically arranged with the guide shaft and a translation component capable of driving the annular push plate to translate axially along the guide shaft.

[0012] In the above-mentioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the translation component includes a rodless cylinder seat fixed on the fixing base and located on the side of the yarn bobbin fixing structure. A rodless cylinder is slidably disposed on the rodless cylinder seat. The piston rod of the rodless cylinder is arranged parallel to the guide shaft.

[0013] In the above-mentioned yarn bobbin fixing mechanism for weaving two-color interwoven mesh polyester fabric, the outer surface of the arc-shaped sleeve plate is also rotatably connected with several ball bearings.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. The No. 1 rotary drive component can drive the rotary seat to rotate, thereby adjusting the position of the two yarn bobbin fixing components on the rotary seat, which facilitates the loading and unloading of yarn bobbins. The yarn bobbin fixing structure with adjustable outer diameter on the fixing seat can be adjusted according to the inner diameter of the yarn bobbin, which can be adapted to yarn bobbins of various sizes and has high practicality. The bobbin unloading component on the fixing seat can also automatically push the yarn bobbin off the yarn bobbin fixing structure after the yarn is used up, realizing automatic unloading.

[0016] 2. The rotating component No. 2 drives the lead screw to rotate. Under the action of the threads set in opposite directions at both ends of the lead screw, it can drive the two sliding sleeves at both ends of the lead screw to move closer or further apart. When the two sliding sleeves move closer together, they can drive the arc-shaped sleeve plate to move outward through the connecting rod, thereby increasing the outer diameter of the center sleeve of the yarn tube. When the two sliding sleeves move further apart, they can drive the arc-shaped sleeve plate to move inward through the connecting rod, thereby decreasing the outer diameter of the center sleeve of the yarn tube, thus realizing the adjustment of the outer diameter of the center sleeve of the yarn tube.
