Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a sizing machine return shaft device. Background Technology

[0002] In the sizing process, warp rewinding (also known as "re-moistening warp") refers to the operation of rewinding a portion of the warp beam after sizing and drying, and returning it to the sizing tank for secondary processing due to process requirements or quality control. This step is usually used to adjust the sizing penetration rate and moisture regain of the yarn or to compensate for deficiencies in the initial sizing. The sizing machine requires a certain tension to meet process requirements during the unwinding of the yarn on the warp beam, as disclosed in CN201721002818.2, an improved warp beam unwinding device for a sizing machine. However, this existing technology cannot effectively control the tension of the warp beam rewinding. Excessive tension can easily cause yarn breakage, while insufficient tension can lead to yarn slack and tangling. Therefore, a warp beam rewinding device for a sizing machine needs to be developed.

[0017] like Figures 1-3 As shown, a sizing machine return device includes a radial shaft frame 1 and a guide frame 2 arranged side by side.

[0018] Two sets of vertical radial shaft support seats 3 are symmetrically fixed on the radial shaft frame 1. A lower radial shaft 4 and an upper radial shaft 5 are rotatably mounted between the lower and upper parts of each pair of opposing radial shaft support seats 3. The yarn to be unwound is wound on each of the lower radial shafts. When unwinding the yarn, the yarn on each of the lower radial shafts 4 is unwound from the lower radial shaft 4 to the upper radial shaft 5, and is then guided horizontally to the guide frame by each of the upper radial shafts.

[0019] Two vertical first mounting plates 6 are symmetrically fixed at one end of the guide frame 2. First guide rollers 7 are rotatably mounted on both sides of the two first mounting plates 6. The lateral and vertical spacing of the two first guide rollers 7 can be adjusted. Two vertical second mounting plates 8 are symmetrically fixed at the other end of the guide frame 2. Second guide rollers 9 are rotatably mounted between the upper parts of the two second mounting plates 8.

[0020] Two slide grooves 10 are respectively provided on each of the first mounting plates 6 in a centrally symmetrical manner. A matching slide seat 11 is slidably installed inside each slide groove 10. The two slide seats 11 located inside the slide grooves at the same end of the two first mounting plates 6 are arranged opposite to each other, and the two first guide rollers 7 are rotatably installed between the two opposite slide seats 11.

[0021] A drive mechanism is provided between the two first mounting plates 6 to drive the slide blocks 11 at both ends to move in opposite or opposite directions in the vertical direction. In this embodiment, the drive mechanism includes two sets of symmetrically rotatably mounted sprockets 12 on the outer sides of the two first mounting plates 6. Each set of sprockets 12 consists of two sprockets, which are rotatably mounted on the upper and lower outer sides of the corresponding first mounting plate 6. A chain 13 adapted to the two sprockets 12 located on the same first mounting plate 6 is installed between them. A drive motor 14 for driving the corresponding sprocket 12 to rotate is installed on the upper inner side of one of the first mounting plates 6. The two sprockets located at the lower ends of the two first mounting plates 6 are connected by a transmission shaft 15.

[0022] Two slide blocks 11, which are slidably mounted on the same first mounting plate 6, are respectively fixedly connected to the left and right sides of the corresponding chain 13. Specifically, a connecting block 16 is fixedly provided at one end of each slide block 11 located on the outside of the first mounting plate 6, and the connecting block 16 is fixedly connected to the side of the chain 13.

[0023] Each of the slide blocks 11 has a horizontal drive cylinder 17 fixedly installed at one end inside the first mounting plate 6. The telescopic end of each drive cylinder 17 is fixedly connected to the mounting seat 18 with an L-shaped cross section. The two first retraction guide rollers 7 are rotatably installed between the two opposite mounting seats 18.

[0024] In operation, the yarn unwinding from the upper radial shaft of the radial shaft frame of this invention is... Figure 1 The yarn is guided into the sizing tank of the sizing machine via two first and second back-winding guide rollers. The vertical height of the two first back-winding guide rollers can be adjusted by driving the motor and two sets of sprocket and chain transmission mechanisms to make the two sets of sliding seats at the upper and lower ends move relative to each other or in opposite directions. The horizontal height of the two first back-winding guide rollers can be adjusted by synchronously extending and retracting the two sets of drive cylinders to drive the two pairs of mounting seats to move relative to each other or in opposite directions. Therefore, the back-winding tension of the yarn can be conveniently adjusted by adjusting the distance between the two first back-winding guide rollers, avoiding yarn breakage due to excessive tension or yarn slack due to insufficient tension, and ensuring the effective operation of the sizing back-winding process.
