Technical Field

[0001] This utility model relates to the field of abrasive belt production technology, specifically a material roll placement rack. Background Technology

[0002] In the abrasive belt processing industry, abrasive belt rolls are the core production raw materials. Their storage and transportation efficiency directly affects the continuity of production. The rolls are usually cylindrical in shape and weigh from tens to hundreds of kilograms. During storage, they need to be stacked in an orderly manner with the help of racks for subsequent hoisting or handling operations.

[0003] Existing placement racks mostly use metal frame structures formed by welding angle steel and square steel. Due to the burrs or sharp edges of the metal frame, the material rolls come into direct contact with the metal frame when placed, taken out, or slightly shaken. The surface is prone to friction or collision with the frame, which can easily cause surface scratches, wrinkles, or even damage, increasing the scrap rate of the material rolls. Therefore, we need to propose a material roll placement rack. Utility Model Content

[0004] The purpose of this utility model is to provide a material roll placement rack. The rack and the material roll are separated by the cooperation of a first protective plate and a second protective plate, preventing contact between them. The U-shaped design of the first protective plate avoids sharp edges and increases the fit between the corners of the first protective plate and the surface of the material roll. The collection capacity of the rack can be adjusted by the cooperation of a lifting frame and a positioning mechanism. This solution prevents direct contact between the material roll and the rack, avoiding scratches, wrinkles, or even damage to the surface of the material roll, thus reducing the scrap rate of the material roll and solving the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a material roll placement rack, including a base 1, with support frames 2 welded and fixed on both sides of the base 1, and a protective plate 3 for preventing the material roll from being scratched is provided between the two sets of support frames 2. The two sides of the protective plate 3 are welded and fixed to the surface of the support frame 2, and the bottom end of the protective plate 3 is welded and fixed to the upper surface of the base 1. The protective plate 3 is U-shaped. A positioning mechanism for positioning the material roll support height is provided at the end of the support frame 2 away from the protective plate 3. A lifting frame 4 is slidably connected to the inner cavity of the support frame 2, and a second protective plate 5 for preventing the material roll from being scratched is welded and fixed to the inner side wall of the lifting frame 4.

[0023] In use, the material rolls are placed sequentially into the grooves of the protective plate 3. The base 1 and the two side support frames 2 combine to form a placement frame that supports the protective plate 3. The protective plate 3 separates the placement frame from the material rolls, preventing contact between them. When the material rolls reach the height of the support frame 2, the lifting frame 4 is pulled upwards, causing the protective plate 5 to move upwards. Then, the position of the lifting frame 4 within the support frame 2 is positioned by the positioning mechanism, allowing the height of the lifting frame 4 to be adjusted. By adjusting the height of the two side lifting frames 4, the capacity of the placement frame can be adjusted. This method avoids direct contact between the material rolls and the placement frame, preventing scratches, wrinkles, or even damage to the surface of the material rolls and reducing the scrap rate of the material rolls.

[0024] The inner wall of the support frame 2 is provided with a support groove 6, and a support block 7 is slidably connected to the inner cavity of the support groove 6. The support block 7 is welded and fixed to the surface of the lifting frame 4. The cooperation between the support groove 6 and the support block 7 can support both sides of the lifting frame 4, providing guidance for the movement of the lifting frame 4 within the support frame 2, preventing the lifting frame 4 from deviating in angle when it is raised or lowered, and improving the stability of the lifting frame 4 when it moves.

[0025] The inner wall of the support block 7 has a slot, and the inner cavity of the slot of the support block 7 is provided with a roller 8. The roller 8 is rotatably connected to the inner cavity of the slot of the support block 7 through a bearing. The roller 8 can assist the support block 7 to slide in the support groove 6, improve the smoothness of the support block 7 when moving in the support groove 6, and reduce the friction between the support block 7 and the support groove 6 when the lifting frame 4 moves.

[0026] The positioning mechanism includes a positioning seat 9 welded and fixed to the outside of the support frame 2. The surface of the positioning seat 9 is provided with an adjustment groove 10. The inner cavity of the adjustment groove 10 is provided with a positioning structure for positioning the height of the lifting frame 4. One end of the positioning structure is connected to the lifting frame 4. When the lifting frame 4 is pulled to move, the lifting frame 4 simultaneously drives the positioning structure to slide in the adjustment groove 10. After adjusting the height of the lifting frame 4, the positioning structure is adjusted to position the lifting frame 4, thereby realizing the adjustment of the height of the lifting frame 4.

[0027] The positioning structure includes an adjusting column 12 located in the inner cavity of the adjusting groove 10 and positioning grooves 11 opened on both sides of the adjusting groove 10. The inner cavity of the positioning groove 11 is connected to the inner cavity of the adjusting groove 10. One end of the adjusting column 12 is welded and fixed to the surface of the lifting frame 4, and the other end of the adjusting column 12 is welded and fixed to the limiting seat 13. A movable seat 14 is provided on the surface of the adjusting column 12. The surface of the movable seat 14 is engaged with the inner cavity of the positioning groove 11. When the lifting frame 4 moves, it synchronously drives the adjusting column 12 to move in the adjusting groove 10, so that the adjusting column 12 drives the limiting seat 13 and the movable seat 14 to move. After adjusting the position of the lifting frame 4, the movable seat 14 is inserted into the inner cavity of the positioning groove 11, so that the position of the lifting frame 4 in the support frame 2 can be fixed.

[0028] The positioning slots 11 are provided in several sets, and the several sets of positioning slots 11 are equally distributed on both sides of the adjustment slot 10. With the setting of several sets of positioning slots 11, the staff only needs to change the position of the adjustment moving seat 14 on the positioning slot 11 to realize the adjustment and positioning of the height of the lifting frame 4, which makes it convenient for the staff to adjust the capacity of the placement frame.

[0029] The surface of the movable seat 14 is provided with a movable hole. The inner cavity of the movable hole is slidably connected to the surface of the adjusting column 12. The movable hole is hexagonal. The shape of the movable hole prevents the movable seat 14 from rotating when it moves, improves the stability of the movable seat 14 when it moves into the inner cavity of the positioning groove 11, and prevents the position of the movable seat 14 from shifting.

[0030] The outer surface of the adjusting column 12 is fitted with a support spring 15 for assisting the movable seat 14 in resetting. The support spring 15 is located between the limiting seat 13 and the movable seat 14. The support spring 15 supports the movable seat 14, provides support force for the movable seat 14, improves the stability of the movable seat 14 in the cavity of the positioning groove 11, and prevents the movable seat 14 from leaving the cavity of the positioning groove 11 after positioning.

[0031] This embodiment also includes handles integrally formed on both sides of the movable seat 14. The handles facilitate the movement of the movable seat 14 by the staff, which provides convenience for the height adjustment of the lifting frame 4.

[0032] This embodiment also includes rubber pads that are glued and fixed to the edges of both the first protective plate 3 and the second protective plate 5. The rubber pads wrap around the edges of the first protective plate 3 and the second protective plate 5 to prevent the edges of the protective plates from scratching the surface of the material roll.

[0033] In practical use: The material rolls are placed sequentially in the grooves of the protective plate 3. The base 1 and the two side support frames 2 are combined to form a placement frame to support the protective plate 3. The protective plate 3 separates the placement frame from the material rolls, preventing contact between them. When the material rolls reach the height of the support frame 2, the handle is pulled outward to move the movable seat 14 out of the inner cavity of the positioning groove 11 and towards the limit seat 13. The movable seat 14 compresses and charges the support spring 15, and then the lifting frame 4 is pulled upward. The lifting frame 4 moves upward in the inner cavity of the support frame 2. After adjusting the height of the lifting frame 4, the movable seat 14 is released, causing the support spring 15 to release and push the movable seat 14 back to its original position. The movable seat 14 is then engaged in the inner cavity of the positioning groove 11, thus positioning the height of the lifting frame 4. This allows for adjustment of the contents of the placement frame. The above scheme avoids direct contact between the material rolls and the placement frame, preventing scratches, wrinkles, or even damage to the surface of the material rolls and reducing the scrap rate of the material rolls.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
