Description

Technical Field

[0001] The utility model relates to the technical field of coiled material unwinding and rewinding, in particular to a coiled material regulating and unwinding device. Background Art

[0002] Traditionally, textile companies have relied on manual inspection, relying on inspectors to visually detect defects on standard inspection machines. Some companies have resorted to manually turning the fabric over, a process that suffers from low detection rates, slow speeds, and high labor intensity. However, the recent emergence of intelligent machine vision inspection machines has revolutionized traditional inspection methods. Despite various current challenges, these machines are gradually replacing manual inspection methods.

[0003] Patent No. 202410063624.1 discloses a tension fine-tuning device for an intelligent cloth inspection machine. The device is equipped with tension fine-tuning devices at both the feed end and the discharge end, so that the cloth can be tensioned during the conveying process. During the unwinding process, the unwinding device can only adjust the unwinding speed, and the roller carrying the cloth cannot adjust its position, resulting in the inability to unwind cloth with a diameter that is too large. In addition, during use, only wound cloth without a center axis can be unwound, and the type is single. Utility Model Content

The lifting slot can ensure that the lifting slider slides accurately in the lifting strip hole, and then the fixing screw is screwed into the threaded through hole to contact the adjustment mounting bracket, and the height is fixed by friction compression.

[0015] Furthermore, because the auxiliary unwinding roller group passes through the adjustment mounting frame and is mounted on the mounting plate, the number of supporting winding cloth rollers is increased, thereby improving the supporting unwinding effect.

[0016] In addition, since the upstream auxiliary unwinding roller and the downstream auxiliary unwinding roller are connected between the upstream rotating plate and the downstream rotating plate, when the unwinding support range is expanded, the upstream rotating plate and the downstream rotating plate can be effectively connected with the fixed unwinding roller group to ensure stable support during unwinding.

[0023] The present invention will be described in further detail below through specific embodiments.

[0024] The longitudinal direction is the fabric conveying direction, and the transverse direction is the direction of the three sets of fixed unwinding rollers.

[0025] like Figures 1 to 4 As shown, a roll material adjustment and unwinding device includes a frame 1, and mounting plates 2 are fixedly installed on both sides of the frame 1 in the horizontal direction. A group of fixed unwinding rollers 3 supporting the winding cloth roller are rotatably installed on the mounting plate 2. The fixed unwinding rollers 3 are driven by an unwinding power device, and movable unwinding roller groups that expand the range of supporting the winding cloth roller are installed on the mounting plate 2 at both longitudinal ends of the fixed unwinding rollers 3. An auxiliary unwinding roller group 21 for assisting the unwinding of the winding cloth roller is also provided on the mounting plate 2 between the fixed unwinding rollers 3 and the movable unwinding roller group.

[0026] In this embodiment, the fixed unwinding roller 3 group consists of two fixed unwinding rollers 3 and are installed horizontally at intervals. The unwinding drive power device includes an unwinding motor 4. The unwinding motor 4 is fixedly installed on the mounting plate 2 and extends an output shaft to drive the two fixed unwinding rollers 3 through a transmission belt. In this way, the fixed unwinding roller 3 can be rotated to enable the winding cloth roller to unwind the cloth.

[0027] like Figure 1 and Figure 4As shown, an adjustment mounting frame 5 is fixedly installed on the mounting plate 2 above the fixed unwinding roller 3 group, and a lifting slider 6 is installed on the adjustment mounting frame 5 for lifting and lowering. The lifting slider 6 is provided with a lifting and fixing device that can be lifted and fixed, and the lifting slider 6 is provided with an arc groove 7 for supporting the central axis of the winding cloth roller; the two ends of the central axis are placed in the arc groove 7 of the lifting slider 6, thereby effectively supporting the winding cloth roller, making the types of unwinding winding cloth rollers more diverse and improving practicality.

[0028] like Figure 2 and Figure 3 As shown, the movable unwinding roller group includes an upstream unwinding roller 8 and a downstream unwinding roller 9, the upstream unwinding roller 8 is deflected and installed on the mounting plate 2 through the upstream rotating plate 10, and the mounting plate 2 is rotatably installed with a clamping plate 11 that cooperates with the upstream unwinding roller 8, and the clamping plate 11 is provided with a plurality of clamping grooves 12 for clamping the upstream unwinding roller 8, and different clamping grooves 12 form different angles with the upstream unwinding roller 8, and the downstream unwinding roller 9 is deflected and installed on the mounting plate 2 through the downstream rotating plate 13, and a deflection plate 14 is provided on the mounting plate 2, and a deflection strip hole 15 is provided on the deflection plate 14, and a limiting rod constrained in the deflection strip hole 15 is provided on the downstream rotating plate 13. , a nut is threadedly installed on the limit rod and pressed against the surface of the deflection plate 14; after the two upstream rotating plates 10 are hingedly installed on the mounting plate 2, the free end is rotated to install the upstream unwinding roller 8, so that it can be deflected, thereby expanding the support range, and then three clamping slots 12 are provided on the clamping plate 11, so that it can correspond to three support ranges to adapt to winding cloth rollers of different sizes, deflect the upstream unwinding roller 8 to the required angle, and then rotate the clamping plate 11 to make the clamping slot 12 clamp the upstream unwinding roller 8, and the downstream unwinding roller 9 swings to the appropriate position along the deflection strip hole 15 and cooperates with the upstream unwinding roller 8, and then tighten the nut to press the deflection plate 14 to complete the fixation, thereby increasing the unwinding range.

[0029] Furthermore, a vertical lifting strip hole 16 is provided on the adjustment mounting frame 5, and lifting grooves 17 constrained in the lifting strip hole 16 are provided on both longitudinal sides of the lifting slider 6. The lifting fixing device includes a threaded through hole 18 opened on the lifting slider 6, and a fixing screw for tightening the adjustment mounting bracket is rotatably installed in the threaded through hole 18; the lifting card slot can ensure that the lifting slider 6 slides accurately in the lifting strip hole 16, and then the fixing screw is screwed into the threaded through hole 18 to contact the adjustment mounting bracket, and the height is fixed by friction compression.

[0030] In this embodiment, the auxiliary unwinding roller group 21 passes through the adjustment mounting frame 5 and is installed on the mounting plate 2. The auxiliary unwinding roller group 21 can effectively support the adjustment mounting frame 5 and can also fix the adjustment mounting frame 5 on the mounting plate 2, thereby ensuring the stability of the installation. At the same time, it increases the number of rollers supporting the winding of the fabric and improves the supporting unwinding effect.

[0031] Furthermore, an upstream auxiliary unwinding roller 19 and a downstream auxiliary unwinding roller 20 are connected between the upstream rotating plate 10 and the downstream rotating plate 13; in this way, when the unwinding support range is expanded, the upstream rotating plate 10 and the downstream rotating plate 13 can be effectively connected with the fixed unwinding roller 3 groups to ensure stable support during unwinding.

[0032] The working principle of this embodiment is as follows: the winding fabric roller is placed on the fixed unwinding roller 3, and the auxiliary unwinding roller group 21 supports the longitudinal sides of the winding fabric roller. Then the unwinding motor 4 drives the fixed unwinding roller 3 to rotate through the transmission belt, and the winding fabric roller starts to rotate to complete the unwinding. When the diameter of the winding fabric roller is too large, the upstream unwinding roller 8 is deflected upward, and then the clamping groove 12 of the clamping plate 11 is clamped downward to clamp the upstream unwinding roller 8 to complete the fixation of the upstream unwinding roller 8. The downstream unwinding roller 9 swings to a suitable position along the deflection strip hole 15 and cooperates with the upstream unwinding roller 8. Then the nut is tightened to press the deflection plate 14 to complete the fixation.

[0033] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solutions of the present invention, without departing from the spirit of the present invention, should fall within the scope of protection defined in the claims of the present invention.
