Description

Technical Field

[0001] This utility model relates to the field of electric roller processing technology, specifically to a placement rack for electric rollers. Background Technology

[0002] An electric roller is a drive device that integrates a motor and a reducer inside the roller. It is widely used in belt conveyor systems. Compared with traditional separate drive devices (where the motor and reducer are external), its core advantages are compact structure, high transmission efficiency, low noise, good sealing, and adaptability to harsh environments such as humidity and dust. When processing electric rollers, it is usually necessary to test them or inject oil inside. However, in order to better support the rollers, electric rollers are usually placed on a rack.

[0003] Existing display racks are typically made of multiple welded plates with grooves for placing the central shaft. While they can accommodate electric rollers, the diameter of the central shaft varies slightly depending on the size of the roller. The fixed-size grooves cannot accommodate electric rollers of different sizes, resulting in a limited overall applicability of the display rack.

[0004] Therefore, we propose a placement rack for electric rollers to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this utility model is to provide a placement rack for electric rollers, in order to solve the problem mentioned in the background art that the existing placement racks on the market are usually made of multiple welded plates with grooves for placing the central shaft. Although they can be used to place electric rollers, the diameter of the central shaft of different rollers varies slightly when placing electric rollers of different sizes. The fixed-size grooves cannot meet the placement of electric rollers of different sizes and types, thus resulting in a small overall applicability of the placement rack.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a placement rack for an electric roller, comprising a support frame and universal wheels with a braking structure installed at the bottom of the support frame. A bearing cross plate is welded to the upper end of the support frame, and a mounting plate is installed on the bearing cross plate. A rotatable movable disc is installed on the mounting plate, and a receiving groove is provided around the circumference of the movable disc. The central shaft of the movable disc is installed through a limiting plate fixed to the side of the mounting plate, and the central shaft of the movable disc is pressed and limited on the limiting plate by a locking member.

[0007] Preferably, multiple load-bearing horizontal plates are evenly distributed at the upper end of the support frame, and two mounting vertical plates are symmetrically distributed at the upper end of the load-bearing horizontal plates.

[0008] By adopting the above technical solution, the ends of the electric roller can be effectively supported by the symmetrically distributed mounting plates on the bearing horizontal plate.

[0009] Preferably, the movable disk is rotatable on the mounting plate, and the movable disk has multiple receiving slots evenly distributed at equal angles around its circumference.

[0010] By adopting the above technical solution and setting multiple receiving slots on the movable plate, the receiving slots can be adjusted by rotating the movable plate.

[0011] Preferably, each receiving slot on the movable disk has a different size, and the central axis in the middle of the movable disk can rotate on the limiting plate.

[0012] By adopting the above technical solution, and by using different sizes of receiving grooves, it is easier to accommodate the placement of electric roller shaft ends of different sizes.

[0013] Preferably, the locking element on the central shaft is a nut, and the surface of the central shaft is provided with an external thread that matches the nut, and the side of the nut facing the limiting plate is provided with a rough surface.

[0014] By adopting the above technical solution, the contact friction between the nut and the limiting plate surface can be improved through the rough surface of the nut.

[0015] Preferably, the supporting horizontal plates located at the left and right ends of the support frame are provided with adjustment guide grooves, and the mounting vertical plates are inserted into the adjustment guide grooves by fixing bolts to achieve locking between the supporting horizontal plates and the mounting vertical plates.

[0016] By adopting the above technical solution and using fixing bolts, it is easy to fix the supporting horizontal plate and the supporting vertical plate.

[0017] Preferably, the adjusting guide groove is configured as an oblong structure.

[0018] By adopting the above technical solution, the waist-shaped adjustment guide groove allows the fixing bolts to be inserted into the adjustment guide groove even after the mounting plate has moved.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the electric roller placement frame is equipped with a rotatable and adjustable disc on the frame body, and multiple grooves of different sizes are opened in the circumference of the disc. When facing electric rollers of different sizes, the corresponding grooves can be adjusted by rotating the disc, thereby improving the overall applicability.

[0020] 1. It is equipped with a movable disc, which can be driven to rotate synchronously by the rotation of the central shaft. The rotation of the movable disc can be used to rotate and switch the receiving slots on it. Since each receiving slot has a different size, it can adapt to the placement of electric roller shafts of different sizes.

[0021] 2. A locking mechanism is provided. The locking mechanism on the central shaft allows for easy clamping and limiting of the central shaft and the movable plate after the movable plate rotates.

[0022] 3. An adjustable guide groove is provided. With the adjustable guide groove of the waist-shaped structure, after the mounting plate is moved on the bearing horizontal plate, the fixing bolts can pass through the adjustable guide groove to complete the limit between the two. By adjusting the movement of the mounting plate, it can adapt to the placement of electric rollers of different lengths. Attached Figure Description

[0030] 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.

[0031] Example 1: Please refer to Figures 1-6Existing placement racks are typically constructed from multiple welded plates with grooves for placing the central shaft. While suitable for placing electric rollers, the fixed-size grooves cannot accommodate rollers of varying sizes due to slight differences in shaft diameter. This limits the overall applicability of the placement rack. To address this issue, this embodiment discloses a placement rack for electric rollers, comprising a support frame 1 and casters 2 with brakes mounted at the bottom of the support frame 1. A load-bearing horizontal plate 3 is welded to the upper end of the support frame 1, and a mounting upright plate 4 is mounted on the load-bearing horizontal plate 3. A rotatable movable disc 5 is mounted on the mounting upright plate 4, and the movable disc 5 has circumferential openings. The movable disk 5 has a receiving groove 6. The central shaft 7 in the middle of the movable disk 5 is installed through and fixed on the limiting plate 8 on the side of the mounting plate 4. The central shaft 7 in the middle of the movable disk 5 is pressed and limited on the limiting plate 8 by the locking member 9. Multiple bearing horizontal plates 3 are evenly distributed on the upper end of the support frame 1. Two mounting plates 4 are symmetrically distributed on the upper end of the bearing horizontal plates 3. The movable disk 5 can rotate on the mounting plate 4. Multiple receiving grooves 6 are evenly distributed at equal angles around the movable disk 5. The size of each receiving groove 6 opened on the movable disk 5 is different. The central shaft 7 in the middle of the movable disk 5 can rotate on the limiting plate 8. The locking member 9 set on the central shaft 7 is a nut. The surface of the central shaft 7 is provided with an external thread that matches the nut. The side of the nut facing the limiting plate 8 is set with a rough surface.

[0032] When it is necessary to oil the electric roller or test its placement, the caster wheel 2 is used to facilitate the movement of the support frame 1. After the support frame 1 is moved, the caster wheel 2 is limited by a brake structure. The brake structure here is a prior art structure that is built into the caster wheel 2. Since it is all prior art, the brake structure will not be described in detail here. Then, the shaft end of the electric roller is placed into the receiving groove 6 on the movable plate 5. The movable plate 5 and the mounting plate 4 support the electric roller. If it is necessary to place electric rollers of different sizes, the locking piece 9 on the central shaft 7 is released, and then the central shaft 7 is rotated. After the central shaft 7 rotates, it will drive the movable plate 5 to rotate synchronously. The rotation of the movable plate 5 can be used to change the receiving groove 6 on it, so that the receiving groove 6 of different sizes is facing upwards, which facilitates the placement of the shaft ends of electric rollers of different sizes. After the movable plate 5 is adjusted, the locking piece 9 is tightened again to press the locking piece 9 against the limiting plate 8, thereby fixing the movable plate 5.

[0033] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. The following technical content is disclosed in this example: Figure 1 and Figure 6As shown, the support horizontal plate 3 located at the left and right ends of the support frame 1 is provided with an adjustment guide groove 10, and the mounting vertical plate 4 is inserted into the adjustment guide groove 10 by fixing bolts 11 to achieve locking between the support horizontal plate 3 and the mounting vertical plate 4. The adjustment guide groove 10 is set as an waist-shaped structure.

[0034] When it is necessary to place the electric roller, loosen the fixing bolt 11. Then push the mounting plate 4 on the bearing horizontal plate 3. After the two mounting plates 4 on the bearing horizontal plate 3 are adjusted, re-insert the fixing bolt 11 into the adjustment guide groove 10 on the bearing horizontal plate 3 to complete the fixing of the bearing horizontal plate 3 and the mounting plate 4. By adjusting the distance between the two mounting plates 4, it can be adapted to the placement of electric rollers of different lengths.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
