Description

Technical Field

[0001] This utility model relates to the field of opening roller technology, and in particular to an adjustable-angle external opening roller. Background Technology

[0002] Spreading rollers are devices used for storing and transporting rolled materials, and they are widely used in industries such as textiles, papermaking, and plastics. When a roll of fabric is unrolled, wrinkles or unevenness can complicate subsequent processing. External spreading rollers, through their special structure and materials, can smooth the fabric by utilizing their lateral stretching and flattening properties.

[0003] Ordinary spreading rollers are directly installed inside the fabric processing machinery, participating directly in the fabric processing. External spreading rollers, on the other hand, are typically installed outside the machine; their relatively independent position makes them easier to maintain and adjust. Using external spreading rollers can significantly reduce wrinkles and unevenness in the fabric during processing, thereby improving the production efficiency of subsequent processes. Existing external spreading rollers are usually positioned directly below the machine tool without any angle, resulting in poor fabric tension. The fabric remains loose during transport and cannot be taut, leading to poor spreading performance.

[0004] Therefore, this utility model provides an external opening roller that can pull the fabric or woven material tighter and achieve a better opening effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an adjustable-angle external opening roller, which solves the problem that the existing external opening rollers do not have a good tensioning effect on the fabric, resulting in poor opening effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adjustable-angle external spreading roller includes an operating table, on the top of which the spreading roller is mounted; a pressing roller is provided at the front end of the spreading roller, and the pressing roller is mounted on an angle adjustment mechanism.

[0008] In this solution, the fabric passes through a pressing roller and a spreading roller in sequence during the fabric production process. The angle adjustment mechanism controls the angle of the pressing roller to increase or decrease the pressure on the fabric, thereby adjusting the tension of the fabric and ensuring that the fabric is taut during transportation, so as to improve the spreading effect of the spreading roller.

[0009] Furthermore, the angle adjustment mechanism includes two adjusting rods, the middle of which is movably connected to two support frames via hinge rods, and the two support frames are respectively set on both sides of the operating table; one end of each adjusting rod is connected to both ends of the pressing roller via a pressing roller fine-tuning assembly; the other end of each adjusting rod is movably connected to the telescopic ends of two hydraulic drive cylinders, and the fixed ends of the hydraulic drive cylinders are set on the operating table.

[0010] In this design, the hydraulic drive cylinder drives the adjusting rod to rotate by extending and retracting. The adjusting rod rotates around the hinge position with the support frame as the center point, and the rotation drives the pressing roller to move up and down. The pressing roller moves down and up, increasing the pressure on the fabric and resulting in a better tensioning effect on the fabric.

[0011] Furthermore, the pressure roller fine-tuning assembly includes an adjusting head, one side of which is connected to an adjusting rod; the other side of the adjusting head has an arc-shaped slot; the rotating shaft at the center of the pressure roller passes through the arc-shaped slot and is connected to a connecting head; the end of the connecting head away from the rotating shaft is flat, and a through hole is provided at the flat position; the bottom of the lifting screw passes through the through hole and is connected to an adjusting nut; the top of the lifting screw is hinged to the tail of the bent shaft, and the root of the bent shaft is connected to the adjusting rod.

[0012] In this solution, rotating the adjusting nut causes it to move along the lifting screw, which in turn moves the connector and the pressing roller along the arc-shaped slot, thereby achieving fine adjustment of the pressing roller and ensuring its levelness; thus avoiding slight tilting of the pressing roller due to errors during equipment installation or angle adjustment mechanism adjustment.

[0013] Furthermore, the opening roller has a central shaft inside, one end of which passes through the left wing of the operating table and is connected to the drive motor; the other end of the central shaft passes through the right wing of the operating table and is connected to the opening roller leveling assembly.

[0014] In this solution, the drive motor drives the opening roller to rotate, and the opening roller leveling component can adjust its height on the right side of the opening roller to keep it in a horizontal state, ensuring that the fabric will not shift during transportation.

[0015] Furthermore, the right wing of the operating table has an arc-shaped waist hole; the opening roller leveling assembly includes a shaft head, the central shaft passes through the arc-shaped waist hole and is connected to the shaft head; a leveling rod is connected to the shaft head, and the other end of the leveling rod is movably connected to the operating surface on the top of the operating table.

[0016] Furthermore, a strip-shaped hole is provided on the operating surface at the top of the operating table; the end of the leveling rod away from the shaft head passes through the strip-shaped hole and is threadedly connected to the leveling nut.

[0017] In this scheme, rotating the leveling nut causes the leveling rod to move up and down. During the movement, the leveling rod drags the central shaft and the opening roller up and down, keeping the opening roller horizontal.

[0018] Furthermore, an annular washer is provided between the leveling nut and the operating surface.

[0019] Furthermore, the central shaft of the spreading roller is connected to the drive motor via a pulley assembly.

[0020] The beneficial effects of this utility model are:

[0021] The adjustable-angle external spreading roller provided by this utility model is equipped with an angle adjustment mechanism to adjust the angle of the pressing roller. During adjustment, a hydraulic drive cylinder drives the adjusting rod to rotate. The adjusting rod rotates around the hinge position with the support frame as the center point. During rotation, the pressing roller moves up and down, controlling the degree of pressing on the fabric, thereby adjusting the tension of the fabric and ensuring that the fabric is in a taut state during transportation. This improves the spreading effect of the spreading roller, making the fabric flat, reducing wrinkles, and improving production efficiency and quality.

[0022] A fine-tuning assembly for the pressing roller is installed at the connection point between the adjusting rod and the pressing roller to adjust the level of the pressing roller. During adjustment, rotating the adjusting nut moves it along the lifting screw, causing the connector and the pressing roller to move along the arc-shaped slot, thus achieving fine-tuning of the pressing roller and ensuring its levelness. The opening roller leveling assembly allows adjustment of its height on the right side of the opening roller to maintain its levelness and prevent fabric shifting during transport.
