Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a roller with a quick assembly structure. Background Art

[0002] Rollers are an important component of belt conveyors. Unlike the previous single horizontal roller that transmits objects, auxiliary mechanisms are installed on both sides of the roller, and the roller is tilted at a certain angle, with one end having a larger diameter and the other end having a smaller diameter, which can assist the roller in the center to push the objects moved there.

[0003] Conventional rollers are mostly customized according to the size and width of the objects to be conveyed. Unless otherwise required, the roller brackets are fixed to the base plate with screws or other tools. The distance between the side rollers and the center roller cannot be easily adjusted, and the tilt angle of the side rollers is also limited, which makes their use quite restrictive.

[0004] Now, a new type of roller with a quick assembly structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a roller with a quick assembly structure to solve the problem of the inconvenience of adjusting the angle of the side roller proposed in the above background technology.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Preferably, the ends on both sides of the auxiliary roller are of different sizes, and the ends on both sides of the main roller are of the same size.

[0008] Preferably, the long sleeve can rotate up and down along the outer wall of the second screw rod, and the short sleeve can rotate up and down along the outer wall of the first screw rod.

[0009] Preferably, the slider 1 and the slider 2 can slide back and forth along the sliding groove, and the positioning bolt can be embedded in the screw hole.

[0010] Preferably, a transverse groove is provided between the two sides inside the bottom plate, and a bidirectional screw rod is movably connected between the two sides inside the transverse groove. A rotary handle is movably connected to the two sides of the bottom plate, and the two sides of the bidirectional screw rod are fixedly connected to the rotary handle respectively. The bidirectional screw rod passes horizontally through the hollow tube, and slots are provided on both sides of the top of the transverse groove.

[0011] Preferably, a clamping sleeve is sleeved on the lower part of the outside of the main roller, and sliding rods are welded on both sides of the bottom of the clamping sleeve, a column is welded at the center of the top of the base plate, and an inner chamber is provided on the inner side of the column, a sliding rod is movably inserted in the inner chamber, and a reinforcement block is welded on the side of the bottom of the slide rod, the internal thread of the reinforcement block is connected with an assembly bolt, an upper limit block is movably connected to the upper part of the outside of the column, and a lower limit block is movably connected to the lower part of the outside of the column, and a spring is welded between the bottom of the clamping sleeve and the column.

[0012] Preferably, the slide bar is embedded in a spring, and the reinforcement block can slide up and down along with the slide bar.

[0013] Preferably, the upper limit block and the lower limit block are in the same vertical plane, and the outer texture of the assembly bolt matches the inner holes of the upper limit block and the lower limit block.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the roller with a quick assembly structure not only realizes the adjustment of the roller support angle and the adjustment of the spacing of the lateral rollers, but also realizes the support of the roller at the center;

[0015] (1) Install an oblique bracket between the two sides of the outside of the auxiliary roller, move the slider 1 or slider 2 along the slide groove at the bottom of the oblique bracket, and rotate the long sleeve and short sleeve corresponding to each of them synchronously, so that the long sleeve lifts the slider 1 along the screw rod 2, and the short sleeve lifts the slider 2 along the screw rod 1. After aligning the screw holes, screw in the positioning bolts to reinforce them, and use the fastening bolts to prevent the long sleeve or short sleeve from swinging. Adjust the angle and height of the auxiliary roller or the oblique bracket, and cooperate with the main roller where the center bracket is located to stably transport objects;

[0016] (2) A bidirectional screw is movably connected between the two sides of the transverse groove. The handle connected to the bidirectional screw is rotated from one side. Since the threads on the two sides of the bidirectional screw are distributed in opposite directions, when the handle is rotated, the hollow tubes on both sides can be guided to disperse or gather. The oblique brackets, auxiliary rollers and other objects carried on the top of the two sets of hollow tubes also move accordingly, thereby achieving the purpose of adjusting the distance between the auxiliary roller and the main roller. The specifications of the objects suitable for pushing are also increasing.

[0017] (3) A sleeve is sleeved under the outside of the main roller. The sleeve at the bottom of the main roller is embedded in the column through two sliding rods and supported by an externally wound spring. If the sleeve is to support the main roller, the spring is allowed to force the sleeve to contact and fit the bottom of the roller body, and the assembly bolts are tightened and the upper limit block is connected to prevent the device from being damaged by excessive weight. If no support is required, the reinforcement block is pressed down and the assembly bolts are used to connect the reinforcement block and the lower limit block to keep the sleeve away from the main roller to prevent the main roller from being squeezed by external force and deformed.
