[0017] The embodiments of the utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are intended to illustrate the utility model, but are not intended to limit the scope of the utility model.

[0018] like Figure 1 As shown, an automatic film unloading vehicle for changing coiled steel cores includes a frame 1 and a replacement assembly 3. Side plates 2 are installed on the upper ends of both sides of the frame 1. Steel unloading assemblies 4 for assisting in the unloading of steel cores are provided on the inner side of the side plates 2. There are two sets of steel unloading assemblies 4. Each steel unloading assembly 4 includes a steel core unloading support plate 401 and an anti-slip mat 402. The surface of the steel core unloading support plate 401 is covered with the anti-slip mat 402. The steel core unloading support plate 401 moves up and down under the drive of the support plate drive cylinder 403. The steel core unloading support plate 401 lifts the steel core that has been coiled and assists in its unloading. The anti-slip mat 402 increases the anti-slip effect. The steel unloading assembly 4 also includes a support plate drive cylinder 403 and a mounting base 404. The support plate drive cylinder 403 is installed at the lower end of the steel core unloading support plate 401, and the mounting base 404 is installed at the bottom of the support plate drive cylinder 403.

[0019] like Figure 2 As shown, the replacement assembly 3 for automatically replacing the coiled steel core is located on the rear side of the side plate 2. The replacement assembly 3 includes an adapter frame 301, a connecting block 302, a spare steel core hook 303, a hook drive cylinder 304, and a connecting column 305. The connecting block 302 is installed on the side of the lower end of the adapter frame 301, and the lower end of the connecting block 302 is connected to the spare steel core hook 303. The two spare steel core hooks 303 are located on the side of the frame 1 near the coiling area. The two spare steel core hooks 303 are used to place the steel core, so that the steel unloading assembly 4 can unload the steel core that has been coiled. The hook drive cylinder 304 is installed on the front side of the connecting block 302. Under the drive of the hook drive cylinder 304, the two spare steel core hooks 303 automatically place the new steel core into the coiling area. The automation level is high, the operation is easy, the number of times the lifting door is opened and closed is reduced, and the product quality is guaranteed. The connecting column 305 is connected to the side of the connecting block 302.

[0020] like Figure 3 As shown, limit plates 5 are provided on the front and rear sides of the unloading steel core pallet 401. The limit plates 5 allow the unloading steel core pallet 401 to be directionally raised and lowered within the side plate 2. A positioning reinforcement plate 6 is installed on the surface of the limit plate 5. An end block 7 is installed on the lower surface of the limit plate 5. The end block 7 limits the limit frame 8, that is, limits the minimum moving height of the unloading steel core pallet 401. A limit frame 8 is provided above the limit plate 5. The limit frame 8 is welded to the unloading steel core pallet 401 as it is raised and lowered. The shape of the limit frame 8 is U-shaped. A movable base frame 9 is installed at the lower ends of both ends of the frame 1. A linear travel pulley 10 is installed inside the movable base frame 9. The linear travel pulley 10 allows the frame 1 to move directionally on the rail between the large aging zone and the winding zone, ensuring the stability of the steel core movement.

[0021] In summary, this automatic film unloading vehicle with rewinding steel core replacement firstly... Figures 1-3The structure shown depicts a PLC-controlled unloading vehicle. Spare steel cores are placed on spare steel core hooks 303. The motor then drives the linear guide pulley 10 to rotate, causing the frame 1 to move directionally along the rails between the aging zone and the winding zone, ensuring the stability of the steel core movement. The two spare steel core hooks 303 are located on the side of the frame 1 closest to the winding zone. During unloading, pressing the switch causes the unloading steel core tray 401 to move upwards under the drive of the tray drive cylinder 403, thus allowing the unloading steel core tray 401 to align with the already wound roll. The steel core is lifted to assist in its unloading and descent. The anti-slip pad 402 increases the anti-slip effect. During lifting and lowering, the limit plate 5 allows the unloading steel core support plate 401 to be directionally lifted and lowered inside the side plate 2. The limit frame 8 moves with the unloading steel core support plate 401. The end block 7 limits the limit frame 8, that is, limits the minimum moving height of the unloading steel core support plate 401. Then, driven by the hook drive cylinder 304, the two spare steel core hooks 303 rise to place the new steel core into the winding area. The system is highly automated, easy to operate, reduces the number of times the lifting door is opened and closed, and ensures product quality.
