[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a scraping strip and a laminating roller, so that the galvanized coil can be continuously unrolled, and the influence of particle garbage carried by the galvanized coil on the unrolling efficiency can be reduced. At the same time, the scraping strip can be adjusted according to the unrolling height to adapt to galvanized coils of different specifications. The laminating roller can improve the unrolling quality of the galvanized coil, and avoid the galvanized coil being offset during the unrolling process, which makes the unrolling work impossible, thereby improving the quality of the finished galvanized coil.

The central axis can be emergency braked through the slot to avoid the different frequencies of the central axis caused by the loss of control of the controller, resulting in stalling of the galvanized coil unwinding and failure to complete the work.

[0021] Reference Figure 1-Figure 4 A precisely controllable galvanized coil unwinding machine comprises a machine body 1, which is the general control unit of the unwinding machine in the prior art. An arc frame 2 is used for setting up a central axis 3 and for limiting the central axis 3 to ensure that the central axis 3 is in the correct horizontal plane, so as to improve the unwinding of the galvanized coil. An auxiliary body is an auxiliary component, which is arranged on both sides of the machine body 1 and mainly plays the role of setting up the central axis 3. Both ends of the central axis 3 are set on the auxiliary body, and the middle section is the position for unwinding the galvanized coil. An auxiliary block is arranged at the rear of the machine body 1 and is mainly used for setting up and driving a laminating roller 11. A controller 7 is the frequency modulation control unit of the central axis 3 in the prior art.

[0022] A plurality of friction strips 4 for improving the unwinding efficiency are provided on the central axis 3. The friction strips 4 are used to increase the friction between the galvanized coil and the central axis 3, thereby reducing the galvanized coil from escaping the control of the central axis 3 and improving the unwinding efficiency of the galvanized coil. The central axis 3 is adapted to the auxiliary body, and the central axis 3 matches the circular groove opened on the top of the auxiliary body. The friction strips 4 are fixedly connected to the central axis 3 by rivets. The rivets can effectively improve the fixing ability of the friction strips 4 and facilitate regular maintenance of the friction strips 4. A slotted groove for emergency stop is provided at one end of the central axis 3. The function of the slotted groove is mainly to perform emergency braking on the central axis 3 in the event of loss of control, and the emergency braking is completed by pressing the slotted groove with a slotted screwdriver as a tool. A motor 6 is provided at one end of the central axis 3, and the motor 6 is fixedly connected to the controller 7. The motor 6 and the controller 7 are prior art.

[0023] A limiting ring 5 for limiting the galvanized coil is provided on the arc frame 2. The limiting ring 5 is used to plan the length of the friction strip 4. Before the galvanized coil is unwound more than half, the friction between the galvanized coil and the arc frame 2 is reduced, while improving the aesthetics of the galvanized coil and reducing the quality loss of the galvanized coil due to friction. The limiting ring 5 is adapted to the central axis 3, and the inner circle of the limiting ring 5 has the same diameter as the central axis 3. The limiting ring 5 is against the side wall of the arc frame 2. The limiting ring 5 can be removed through one of the arc frames 2, separated from the central axis 3 and maintained.

[0024] A scraping strip 8 for removing particles is provided on the arc frame 2. The scraping strip 8 mainly removes particles and garbage carried on the surface of the galvanized coil, reduces the impact of particle garbage on the unwinding work, and thus reduces the quality of the finished galvanized coil. A plurality of mounting grooves are provided on one side of the arc frame 2. The mounting grooves are used to place the scraping strip 8. The scraping strip 8 is fixed in the mounting grooves by fasteners. The scraping strip 8 is provided with an oblique angle for scraping off particles. The oblique angle is conducive to contacting the surface of the galvanized coil, and at the same time has the function of guiding particles and garbage away from the surface of the galvanized coil.

[0025] The auxiliary block is symmetrically provided with laminating rollers 11 for reducing the dispersion of the galvanized coil. The laminating roller 11 is an auxiliary component, which is mainly used to maintain the current direction of the galvanized coil. The auxiliary block is provided with multiple support columns 9, which are support components and are fixed to the auxiliary block by welding. The support columns 9 are symmetrically provided with erection rods 10. There are two erection rods 10 in total, which are used for the laminating roller 11 to be synchronized with the unwinding process of the galvanized coil, and the erection rod 10 is rotatably connected to the support column 9 through an auxiliary shaft. The diameter of the galvanized coil gradually increases, and the laminating roller 11 moves upward following the diameter of the galvanized coil. The auxiliary shaft helps the laminating roller 11 to move on the support column 9. The laminating roller 11 is fixedly connected to the erection rod 10 through the auxiliary rod, and the auxiliary rod is a connecting component.

[0026] The machine body 1 is symmetrically provided with fixed angles 13 for disassembling the arc frame 2. The fixed angle 13 is a fixing component of the arc frame 2, which is convenient for disassembling the arc frame 2 on the right side of the machine body 1, and removing the unwound galvanized coil from the central axis 3. A fixing buckle 12 for limiting the central axis 3 is provided at one end of the auxiliary body. The fixing buckle 12 is used to limit the central axis 3, and is the central axis 3 on the auxiliary body on the right side of the machine body 1, increasing the fixing ability. The fixed angle 13 is fixedly connected to the machine body 1 by rivets, and the rivets are detachable tools.

[0027] The working principle of the utility model is as follows: one end of the galvanized coil is curled on the central axis 3, and then a controller 7 is set to make the central axis 3 rotate continuously according to the frequency. The diameter of the galvanized coil gradually increases under continuous rotation. At the same time, the scraping strip 8 will remove the particles and garbage on the galvanized coil, and the bonding roller 11 will guide the galvanized coil to the correct direction, reducing the problem of offset direction and causing the appearance of the galvanized coil to decrease. After unwinding, the fixed angle 13 is disassembled, and the right arc frame 2 can be removed, and then the unwound galvanized coil can be taken out from the central axis 3.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
