[0028] By movably connecting the base frame 1, the base plate 2 and the support plate 3, it is convenient to independently adjust the base plate 2 and the support plate 3, and the square column tube 5 is driven to deflect in the inner cavity of the base frame 1 through the adjustment component 8, so as to adjust the angle between the base plate 2 and the base frame 1, and switch the horizontal and vertical states of the dry film roll. Then, the first motor 9 drives the screw 10 to rotate in the threaded sleeve 11, so that the support plate 3 drives the support column 4 to push multiple groups of dry film rolls horizontally, and transfer the dry film rolls to the storage rack. During the transfer process, the dry film rolls are still kept from contacting each other, reducing the risk of being scratched. In conjunction with the telescopic component 7, the dry film rolls can be stored on storage racks at different heights.

[0029] The telescopic assembly 7 includes a second motor 71 fixed in the inner cavity of the square cylinder 5, and a first threaded rod 72 is fixed to the output shaft of the second motor 71.

[0035] A fixed column 20 is fixed to the end of the movable rod 84, and the connecting plate 85 is sleeved on the outside of the fixed column 20. A sliding groove 21 is opened in the inner cavity of the base frame 1, and the end of the fixed column 20 away from the movable rod 84 passes through the inner cavity of the sliding groove 21. Through the setting of the fixed column 20, not only can the connecting plate 85 and the movable rod 84 be movably connected, but the fixed column 20 can also slide in the sliding groove 21 to limit the movable rod 84, thereby ensuring that the movable rod 84 moves smoothly inside the base frame 1.

[0036] A plurality of groups of moving wheels 22 are installed at the bottom of the base frame 1, and a trolley handrail 23 is installed on the side of the base frame 1. A controller 24 is installed on the trolley handrail 23. Through the setting of the trolley handrail 23 and the moving wheels 22, the device can be moved and the dry film roll can be moved quickly. Then the controller 24 can control the device and operate to transfer the dry film roll.

[0037] A notch is provided on the side of the fixing rod 86 away from the square cylinder 5, which is aligned with the second threaded rod 82. A protective pad is provided on the top of the support plate 3. The notch is provided to prevent the fixing rod 86 from colliding with the second threaded rod 82. The protective pad is used to protect the dry film roll to prevent the device from being shaken during the transfer process, which may cause scratches on the contact surface between the dry film roll and the support plate 3.

[0038] When in use, the dry film roll is vertically inserted into the support column 4 so that the dry film roll is stored independently, and then the trolley handrail 23 is used to transfer the device and the dry film roll. When the device is moved to the storage rack, the vertically placed dry film roll needs to be placed horizontally on the storage rack. At this time, the third motor 81 is started by the controller 24, and the third motor 81 drives the second threaded rod 82 to rotate, and cooperates with the second screw sleeve 83 to move the movable rod 84. The movable rod 84 pushes the connecting plate 85 through the fixed column 20, and then the connecting plate 85 pushes the fixed rod 86, so that the fixed rod 86 and the square column tube 5 are deflected upward under the support of the support spring 15. , when the square cylinder 5 is adjusted from horizontal to vertical and then stops, the dry film roll sleeved on the support column 4 is also adjusted from vertical to horizontal, and then the second motor 71 is started according to the specific situation, the second motor 71 drives the first threaded rod 72 to rotate, and the second screw sleeve 83 is used to drive the movable block 73, so that the movable block 73 drives the fixed frame 6 to lift the base plate 2 to adjust the height of the dry film roll. When the dry film roll is flush with the storage rack, the first motor 9 is started, the first motor 9 drives the screw 10 to rotate, and the threaded sleeve 11 is used to drive the support column 4 and the support plate 3 to separate from the base plate 2, and the dry film roll is pushed flat onto the storage rack.
