Description

Technical Field

[0001] This utility model relates to the field of turnover equipment technology, and in particular to a bottom film turnover vehicle. Background Technology

[0002] like Figure 1 As shown, the base film material is generally in roll form (i.e., base film material roll 100), and it is relatively large and heavy. During the turnover process, a turnover vehicle is required. The conventional method is to place the base film material roll directly on the turnover vehicle and then fix it with ropes. This method can easily damage the surface base film material during turnover. In addition, because the base film material is in roll form, it is not easy to fix it on the turnover vehicle, and there is a risk of it rolling or slipping during turnover. Furthermore, the turnover process requires multiple people to operate, which wastes manpower.

[0003] In view of this, it is necessary to improve the existing turnover vehicles in order to solve the above problems. Utility Model Content

[0027] like Figures 2-5As shown, this utility model discloses a bottom film turnover cart 200, including a cart bottom plate 1. Preferably, the cart bottom plate 1 is made of stainless steel. A handrail 2 is provided on the left side of the cart bottom plate 1. A hook 5 is provided at the top of the handrail 2. A support plate 10 is provided on the handrail 2 below the hook 5. A limiting cover 4 is rotatably connected to the support plate 10 via a rotating assembly. The limiting cover 4 has a C-shaped structure with its opening facing downwards. A handle 6 is provided on the surface of the limiting cover 4 facing the handrail 2. Pulling the handle 6 towards the handrail 2 allows the handle 6 to be hooked onto the hook 5. A tray 3 is provided on the cart bottom plate 1. Preferably, the tray 3 is made of TPU material. The surface of the tray 3 has an arc-shaped limiting groove 31, and the tray 3 is located below the limiting cover 4. The two are directly opposite each other, with the limiting cover 4 limiting the upper part of the bottom film roll 100 and the tray 3 limiting the lower part of the bottom film roll 100. The upper and lower parts cooperate to ensure stability during the turnover process. The rotating assembly includes a rotating shaft 7, a shaft seat 8, a locking ring 12, and a shaft locking handle 9. Both ends of the rotating shaft 7 are rotatably connected to the support plate 10 via a shaft seat 8. A locking ring 12 is provided on the rotating shaft 7 on the inner side of each of the two shaft seats 8. The outer ring of the locking ring 12 is fixedly connected to the limiting cover 4. In this embodiment, it is connected to the end closest to the support plate 10, i.e., the left vertical plate 41. The locking ring 12 has an axial opening on the side away from the limiting cover 4. The shaft locking handle 9 can lock the opening from top to bottom by rotation, thus locking the locking ring 12 to the rotating shaft 7. To facilitate movement, the bottom of the vehicle floor 1 is provided with four casters 11. At least two casters 11 near the armrest 2 have a braking function, and the total load of the four casters 11 is greater than 300 kg.

[0028] like Figure 6 and Figure 7 As shown, the limiting cover 4 includes five end-to-end limiting plates: a left vertical plate 41, a left inclined plate 42, a horizontal plate 43, a right inclined plate 44, and a right vertical plate 45. In this embodiment, the limiting cover 4 is formed by bending five segments of sheet metal in sequence. The length L1 of the left vertical plate 41 is less than the length L2 of the right vertical plate 45, and the length L3 of the left inclined plate 42 is less than or equal to the length L4 of the right inclined plate 44. In this embodiment, the left vertical plate 41 and the right vertical plate 45 are parallel, and the directions of the left inclined plate 42 and the right inclined plate 44 are symmetrical along the horizontal plate 43. Multiple triangular reinforcing ribs 47 are welded along the width direction at the joints of adjacent limiting plates. The included angles between adjacent limiting plates are equal, i.e., the included angle α is 135°. The edges of each limiting plate are provided with upward-folded flanges 46.

[0029] Working principle: such as Figure 2 and Figure 3As shown, during use, the bottom film roll 100 is placed in the arc-shaped limiting groove 31 of the tray 3. Then, the handle 6 is removed from the hook 5, and the limiting cover 4 is rotated downwards so that the limiting cover 4 is pressed down above the bottom film roll 100. The inner surfaces of the horizontal plate 43, the right inclined plate 44, and the right vertical plate 45 are all in close contact with the surface of the bottom film roll 100, thus restricting the bottom film roll 100 inside the limiting cover 4. This achieves the fixation of the bottom film roll 100 and prevents the bottom film roll 100 from rolling off during turnover. The limiting plate and the bottom film roll 100 are in planar contact, which avoids damage to the surface of the bottom film.

[0030] After the limit cover 4 is adjusted into place, the position of the limit cover 4 is locked by rotating the shaft and tightening the handle 9 to prevent the limit cover 4 from shaking during the turnover process.

[0031] Once the rotation is in place, open the limit cover 4, as follows: Figure 8 As shown, the handle 6 of the limit cover 4 is hung on the hook 5, which prevents the limit cover 4 from falling after it is opened and improves safety.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
