Description

Technical Field

[0001] The utility model relates to the technical field of material strip processing, in particular to a material strip supporting frame which is easy to adjust. Background Art

[0002] In the process of plastic modification and granulation, the material strip is extruded from the extruder die, cooled in the cooling water tank, and then removed by the water dispenser, and finally enters the pelletizer for pelletizing. A transition device is provided between the cooling water tank and the water dispenser. The commonly used transition device is a material strip support. Generally, a long strip roller is provided on the material strip support. The long strip roller rolls to assist the transfer of the material strip. Due to the long length of the long strip roller, it will cause difficulty in rotation, affecting the normal delivery of the material strip.

[0003] In order to solve the above problems, the utility model with the authorization announcement number CN214238997U discloses a material strip support. The material strip support includes: a support body, a plurality of rollers and a limiting mechanism. The support body includes two support plates spaced apart along a first direction, and a fixed shaft is arranged between the two support plates; a plurality of rollers are spaced apart along the first direction; the rollers are rotatably arranged on the fixed shaft; an annular groove is provided on the circumferential outer wall of the roller, and the material strip is partially accommodated in the groove along the conveying direction to limit the deviation of the material strip along the first direction; a limiting mechanism is provided at both ends of each roller along the first direction to limit the movement of the roller along the first direction. The problem of deformation or breaking of the material strip is avoided by arranging a plurality of rollers at intervals; an annular groove is provided circumferentially on the roller to avoid entanglement and adhesion between the material strips; and limiting mechanisms are provided at both ends of the roller to stabilize the transmission of the material strip and ensure the effective transmission of the material strip.

[0004] In the above-mentioned prior art, in order to prevent the material strips from being entangled and adhering to each other, annular grooves are opened on the rollers so that the material strips can fall into the annular grooves respectively during the transmission process. However, in the actual process, due to the inconsistent specifications and widths of the material strips, when the width of the material strip is larger than the annular groove, the function of the annular groove is ineffective; when the width of the material strip is too smaller than the annular groove, two material strips can fall into the annular groove at the same time, which also causes the function of the annular groove to fail.

[0005] Therefore, since the width of the annular groove on the roller is fixed, the entire bracket cannot adapt to material strips of different production specifications, resulting in reduced practicality. Utility Model Content

[0035] See also Figures 1 to 6 The embodiment of the present application provides a material strip support frame that is easy to adjust, including a support, a first telescopic support rod 2, a second telescopic support rod 3, a rotating shaft 4 and a roller 5. The support is provided with a first telescopic support rod 2 and a second telescopic support rod 3, and the first telescopic support rod 2 and the second telescopic support rod 3 are rotatably connected with a rotating shaft 4 through a bearing; a plurality of rollers 5 are provided on the rotating shaft 4, and the rollers 5 include a first annular sleeve 51 and a second annular sleeve 52, a first convex strip 53 is provided on one side of the first annular sleeve 51, and the first convex strip 53 is arranged in a circumferential array on one side of the first annular sleeve 51, a second convex strip 54 is provided on one side of the second annular sleeve 52, and the first annular sleeve 51 and the second annular sleeve 52 are spliced ​​and connected by the first convex strip 53 and the second convex strip 54, and a fixing device 6 is provided on the other side of the first annular sleeve 51 and the first annular sleeve 51.

[0036] Working principle and effect:

[0037] During use, the rotating shaft 4 is adjusted to the required height for conveying the material strip by the first telescopic support rod 2 and the second telescopic support rod 3, and then the first annular sleeve 51 in the roller 5 is fixed on the rotating shaft 4 by the fixing device 6. After the fixing is completed, the second annular sleeve 52 in the roller 5 is moved so that the width of the groove formed by the splicing of the first convex strip 53 and the second convex strip 54 is adapted to the width of the material strip (specifically, the first convex strip 53 is fixed as the second annular sleeve 52 is fixed, and at this time, it is only necessary to move the second annular sleeve 52 to drive the second convex strip 54 to move. When the width of the material strip is wider, the second annular sleeve 52 is moved in a direction away from the first annular sleeve 51, so that the second convex strip 54 is moved in a direction away from the first convex strip 53. When the width of the material strip is small, the second annular sleeve 52 is moved toward the direction close to the first annular sleeve 51, so that the second convex strip 54 is moved toward the direction close to the first convex strip 53, thereby reducing the width of the splicing slot formed by the first convex strip 53 and the second convex strip 54 to adapt to the material strip with a small width). After the second annular sleeve 52 is moved, the second annular sleeve 52 is fixed by the fixing device 6 on one side of the second annular sleeve 52, and the rotating shaft is rotated between the first telescopic support rod 2 and the second telescopic support rod 3 through the bearing, thereby driving the roller 5 on the rotating shaft to rotate together, and the material strip conveying work can be realized.

[0038] The roller 5 is configured to be a combination structure of a first circular sleeve 51 and a second circular sleeve 52, and a groove is formed by splicing the first convex strip 53 and the second convex strip 54. Before the material strip conveying work starts, the operator can adjust the distance between the first convex strip 53 and the second convex strip 54 according to the width of the material strip, so that the width of the groove is adjusted, and then the groove can adapt to material strips of different specifications and widths, which greatly improves the practicability of the device; and a fixing device 6 is provided on the first circular sleeve 51 and the second circular sleeve 52 to fix the first circular sleeve 51 and the second circular sleeve 52 with the adjusted distance, so as to avoid the first circular sleeve 51 and the second circular sleeve 52 from being offset due to rotation during the conveying process, and then the rotation of the rotating shaft 4 and the roller 5 is realized through the bearing.

[0039] In one embodiment, Figure 1 and Figure 4As shown, the first telescopic support rod 2 includes an upper part 21 and a lower part 22, the bottom end of the lower part 22 is connected to the bracket, and the upper end of the lower part 22 is hinged to the bottom end of the upper part 21 through a hinge 23. Further, a vertical plate is provided on the top of the lower part 22, and a rotating shaft is provided on the vertical plate. Two baffles are provided at the bottom of both sides of the upper part 21, and the two baffles are arranged on both sides of the vertical plate and are rotatably connected with the rotating shaft. The vertical plate and the two baffles are both semicircular plates. In the actual operation process, when the upper part 21 is rotated and lifted, the baffle rotates around the rotating shaft on the vertical plate, thereby lifting the first rotating shaft 42, and the operation is simple and fast.

[0040] In one embodiment, Figures 2 to 3 As shown, a plurality of mounting holes 41 are arranged in an array on the rotating shaft 4. The roller 5 is fixed on the rotating shaft 4 through the mounting holes 41.

[0041] In one embodiment, Figures 2 to 3 As shown, the fixing device 6 includes a fixing ring 61, a threaded hole is provided on the fixing ring 61, the threaded hole is matched with the mounting hole 41, a threaded rod 62 is provided in the threaded hole, and nuts are provided at the upper and lower ends of the threaded rod 62. The threaded hole is aligned with the mounting hole 41 on the rotating shaft 4, the threaded rod 62 is inserted from the top of the threaded hole and penetrates the mounting hole 41, and passes out to the bottom of the threaded hole, and finally the threaded rod 62 is fixed to the fixing ring 61 from the upper and lower ends by two nuts, so that the fixing ring 61 is fixed to the rotating shaft 4.

[0042] Furthermore, one side of the fixing ring 61 is connected and fixed to one side of the first circular ring sleeve 51 and the second circular ring sleeve 52 in the roller 5. In actual operation, the first circular ring sleeve 51 is first fixed by the fixing ring 61 on one side of the first circular ring sleeve 51, and then the width of the groove is determined according to the splicing of the first convex strip 53 and the second convex strip 54.
