Problems solved by technology

In the above production process, the pulling roller squeezes the cylindrical fabric for the first time, and the fabric rolling roller squeezes it for the second time, and the two squeezes act on the same position of the cylindrical fabric, and the creases are relatively stubborn. Affect the appearance and quality of the finished product
Taking spandex elastic fabric as an example, after the cylinder is flattened into double layers, creases are formed at both ends, which are difficult to eliminate in the subsequent finishing or opening process, which affects the quality of finished products of downstream manufacturers

Embodiment 1

[0027] Such as figure 1 It can be seen that the elastic fabric forming device dedicated to the circular weft machine of this embodiment includes a frame 1, and a cloth frame 2 is suspended above the frame 1, and is characterized in that: one of the two side frames of the frame 1 A first shaft 3a, a second shaft 3b, and a third shaft 3c are arranged parallel to each other, and a pulling rubber roller 30 is arranged on the first shaft 3a, the second shaft 3b, and the third shaft 3c. Cloth frame 2 and pulling rubber roller 30 are centrally arranged along the center line of frame 1, and the length of described pulling rubber roller 30 is less than the lateral extension length of cloth frame 2, and described first axis 3a, second axis 3b. The length of the third shaft 3c is greater than the length of the pulling rubber roller 30 ; the finished product box 4 is arranged under the frame 1 .

[0028] After adopting the above-mentioned technical scheme, the cylindrical fabric is conve...

Embodiment 2

[0030] Such as figure 2 , image 3 It can be seen that on the basis of the first embodiment, this embodiment also includes a swing bar device arranged along the width direction of the finished box 4 . The pendulum device is used to make the fabric move back and forth along the width direction of the finished box 4 to improve the consistency of the finished product.

[0031] As one of the implementations, the swing link device includes a pin shaft 50 arranged on the side of the frame 1, a connecting rod 5 is movably arranged on the pin shaft 50, and the middle part of the connecting rod 5 is limited along its length. Position slot 51; also includes a turntable 7 that is axially connected to the inside of the frame 1, and a limit pin 70 is fixed perpendicular to the surface of the turntable 7, and the limit pin 70 passes through the limit slot 51; the connecting rod 5 Two swing rods 6 parallel to each other are arranged at the end, and there is a gap between the two swing rod...

Embodiment 3

[0036] Such as Figure 4 , Figure 5 It can be seen that the difference from the second embodiment is that in this embodiment, the driving mechanisms of the swing link device are all arranged inside the frame 1 .

[0037] A drive wheel 31 is arranged on the shaft inside the frame 1, and the drive wheel 31 is connected with the turntable 7 through a transmission belt. In order to ensure the smooth traction of the fabric, the length of the first shaft 3a, the second shaft 3b, and the third shaft 3c must be greater than the lateral extension length of the cloth frame 2; and in the present invention, the length of the pulling rubber roller 30 is less than the cloth frame 2 The horizontal extension length of the frame 1 makes the three shaft ends inside the frame 1 all have a length margin, which provides the installation space for the driving wheel 31, and the equipment structure is more compact.

[0038] In Embodiment 1, the two swing rods 6 are fixed at the ends of the connect...

Abstract

The invention provides an elastic fabric lapping device special for a circular knitting machine. The lapping device can enable a cylindrical fabric to be stacked in a lapping manner, a finished product is free of a folding mark, and the quality and the appearance are improved remarkably. A fabric holding frame is suspended above a rack, a first shaft, a second shaft and a third shaft are arranged between two side frames of the rack in parallel, pulling rubber rolls are arranged on the first shaft, the second shaft and the third shaft, the fabric holding frame and the pulling rubber rolls are arranged in the middle along the center axis of the rack, the lengths of the pulling rubber rolls are smaller than the horizontal stretching length of the fabric holding frame, and the lengths of the first shaft, the second shaft and the third shaft are larger than those of the pulling rubber rolls; a finished product box is arranged below the rack. The device further comprises swing rod devices which are arranged in the width direction of the finished product box.

Description

technical field [0001] The invention relates to textile machinery, in particular to a circular weft woven fabric forming device. Background technique [0002] Cylindrical fabrics are generally produced by weft knitting machines, then flattened into double layers by a pair of pulling rollers or three pulling rollers, and then rolled into cloth rolls by cloth rolling rollers. In the above production process, the pulling roller squeezes the cylindrical fabric for the first time, and the fabric rolling roller squeezes it for the second time, and the two squeezes act on the same position of the cylindrical fabric, and the creases are relatively stubborn. Affects the appearance and quality of the finished product. Taking spandex elastic fabric as an example, after the cylinder is flattened into double layers, creases are formed at both ends, which are difficult to eliminate in the subsequent finishing or opening process, which affects the quality of finished products of downstrea...
