[0025] Refer to Figures 1 to 5As shown in the figure, an unwinding device for roll pressing and loading of metal strip coils includes a base 1, a driving assembly 3 provided on the base 1, and an unwinding assembly 2 connected to the driving assembly 3. The unwinding assembly 2 is used to install metal strip coils, and the diameter of the unwinding assembly 2 can be adjusted to adapt to metal strip coils with different inner diameters. The unwinding assembly 2 includes a turntable 21, the turntable 21 is connected to the power output end of the driving assembly 3, a screw 24 is provided on the side of the turntable 21, a sliding sleeve is provided on the screw 24 and is matched with it. The inner side of the sliding sleeve has a thread matched with the screw 24. Four support plates 22 connected by connecting rods 25 are circumferentially and evenly distributed on the side of the sliding sleeve. The support plates 22 are provided with connecting parts at one end close to the turntable 21. A third chute 211 is provided on the turntable 21. A pulley is provided at the part where the connecting part passes through the third chute 211 and protrudes. Rotating the screw 24 drives the sliding sleeve to move in the axial direction of the screw 24, and through the cooperation of the connecting rod 25 and the turntable 21, the four support plates 22 expand / contract outwards.

[0026] A fixed baffle 221 is provided on the support plate 22. A retaining frame 23 is slidably fitted on the support plate 22. A block 231 that can move up and down is provided on the retaining frame 23. A toothed part 222 matched with the block 231 is provided on the upper end surface of the support plate 22. The toothed part 222 is arranged in a straight line. When the block 231 is inserted into the toothed part 222, the movement of the retaining frame 23 away from the baffle 221 is restricted, but the movement of the retaining frame 23 towards the baffle 221 is not restricted. The block 231 is integrally a right-angled trapezoidal block, and an inclined surface is provided at its bottom, and the inclined surface is inclined towards the baffle 221. After the metal strip coil is sleeved on the support plate 22, the retaining frame 23 is pushed to clamp the metal strip coil between the baffle 221 and the retaining frame 23, and the block 231 is inserted into the toothed part 222 to prevent the retaining frame 23 from moving away from the baffle 221.

[0027] Furthermore, a first cross bar 232 and a second cross bar 233 are provided on the retaining frame 23. A vertical first chute is provided on the block 231. The first cross bar 232 passes through the first chute and is slidably fitted with it. The second cross bar 233 is provided above the first cross bar 232. A spring 234 is provided between the second cross bar 233 and the block 231. The block 231 is pressed downwards by the spring 234, so that the block 231 is at the lowest point and inserted into the toothed part 222 in the normal state. When it is necessary to move the retaining frame 23 away from the baffle 221, the block 231 is pulled up to separate it from the toothed part 222, and then the retaining frame 23 can be slid.

[0028] Furthermore, second sliding grooves are provided on both sides of the support plate 22. The retaining frame 23 is provided with a sliding portion 235 that cooperates with the second sliding grooves. The second sliding grooves are open at one end away from the baffle 221. The retaining frame 23 can be disassembled / assembled from the opening, facilitating the disassembly and assembly of the retaining frame 23. When installing a metal coil, the retaining frame 23 needs to be removed first. After the metal strip coil is placed, the retaining frame 23 can be combined with the support plate 22 and directly pushed in along the second sliding groove without pulling up the clamping block 231. When the retaining frame 23 needs to be removed, one hand pulls up the clamping block 231 and the other hand pushes the retaining frame 23 out along the second sliding groove. The operation is more convenient, and removing the retaining frame 23 is more conducive to the loading and unloading of the metal strip coil and is not likely to cause position interference during installation.

[0029] Furthermore, a plummer block bearing 26 is provided on the side of the turntable 21. The plummer block bearing 26 is connected to the screw rod 24, facilitating the rotation of the screw rod 24.

[0030] Furthermore, the driving assembly 3 includes a motor 31, a motor controller 32, and a speed reduction transmission element 33. The motor 31 is driven by the motor controller 32 and the rotation speed of the motor 31 can be adjusted. The motor 31 drives the turntable 21 to rotate through the speed reduction transmission element 33. The motor controller 32 can also be connected to an external control device, such as the driving device of a roll press, to automatically adjust the unwinding speed according to the rolling speed.

[0031] Furthermore, two shaft rollers 4 are provided on the side of the base 1 and below the unwinding assembly 2. When the side of the roll press that requires feeding of the metal strip coil is in a slack state, the tension at one end of the metal strip coil on the roll press side is reduced, that is, when the unwinding amount of the metal strip coil is large and the metal strip sags, the shaft rollers 4 can support the bottom of the metal strip.

[0032] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
