It includes a fixed bracket and a rotating assembly placed on the fixed bracket, the rotating assembly includes a rotating shaft placed horizontally on the fixed bracket through a rolling bearing, and the rotating shaft is equipped with an adjustable support for supporting the steel coil. The present invention adopts a rotating assembly based on the principle of core shaft expansion and contraction, and adjusts the expansion and contraction through its bolts and top screws to achieve the function of supporting the inner ring of the steel coil; through the rolling bearings at both ends of its rotating shaft, it can be flexibly rotated on the fixed bracket to safely and conveniently unfold the steel coil; the overall support of the steel coil by the fixed bracket and the rotating assembly can avoid damage to the surface of the steel coil caused by bumping against the steel coil during the steel coil unfolding operation;

[0003] In the production and processing of electroplated tinplate, the sheet is typically thin, typically ranging from 0.18-0.2mm, and is often unwound at speeds exceeding 100m / min. However, during the unwinding process, when the equipment experiences sudden stops or starts, the speed difference between the inlet and outlet can easily cause wrinkles in the middle section of the steel strip. This not only affects the surface quality of the steel strip, but also increases the rate of production defects, reduces the smoothness of the unwinding operation, and reduces the quality of the finished product.

[0004] Therefore, we designed an electroplated tin plate unwinding device with anti-wrinkle function to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a tinplate unwinding device with an anti-wrinkle function, so as to solve the problem raised in the above background technology that when the equipment suddenly stops or starts, the steel strip in the middle section is very likely to wrinkle due to the speed difference between the inlet and the outlet. This not only affects the surface quality of the steel strip, but also leads to an increase in the production defect rate, reducing the smoothness of the unwinding operation and the quality of the finished product.

[0006] In order to solve the above technical problems, the present invention provides an electroplated tinplate unwinding device with anti-wrinkle function, including a fixed table, the top surface of the fixed table is fixedly connected to a support seat, a conveyor belt is installed on the support seat, a steering roller is provided on one side of the conveyor belt for steering the steel belt, the top surface of the fixed table is fixedly connected to a fan, and the fan is arranged on one side of the conveyor belt.

[0007] Furthermore, two inlet pinch rollers are provided above one end of the conveyor belt, two outlet pinch rollers are provided above the fixed platform, the outlet pinch rollers are located below the steering roller, and a plurality of rollers are provided above the fixed platform, and the plurality of rollers are arranged linearly with the conveyor belt as the reference.

[0009] Furthermore, the plurality of rollers are rotatably mounted between the two second fixed plates.

[0010] Furthermore, two third fixing plates are fixedly connected to the top surface of the fixing platform, and the steering roller is rotatably installed between the two third fixing plates.

[0011] Furthermore, a driving motor is fixedly connected to the bottom of the support base.

[0012] Furthermore, the air suction end of the fan is connected to an air duct, and the air duct is vertically flush with the bottom surface of the conveyor belt.

[0013] Furthermore, the number of the rollers is four.

[0014] Furthermore, the belt is pushed forward by the entrance pinch roller, and after turning at the turning roller, it is adsorbed on the bottom surface of the conveyor belt by the air duct. The rotating conveyor belt drives the steel belt to move. The conveyor belt material is soft to avoid scratching the steel belt. The steel belt naturally droops after following the conveyor belt for a distance, and the roller supports the steel belt.

[0015] Furthermore, the contact area between the roller and the steel belt is small and there is sliding friction, which reduces the scratches on the steel belt. The outlet pinch roller drives the steel belt to continue to push forward. When the steel belt stops or starts suddenly, the speed difference between the front and rear can naturally expand and contract between the inlet pinch roller and the outlet pinch roller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figures 1-4 The present invention provides a technical solution: a tinplate unwinding device with an anti-wrinkle function, comprising a fixed platform 1, a support base 2 fixedly connected to the top surface of the fixed platform 1, a conveyor belt 3 installed on the support base 2, a steering roller 4 is provided on one side of the conveyor belt 3 for steering the steel belt, a fan 5 fixedly connected to the top surface of the fixed platform 1, and the fan 5 is provided on one side of the conveyor belt 3.

[0026] Two entrance pinch rollers 6 are provided above one end of the conveyor belt 3, two exit pinch rollers 7 are provided above the fixed platform 1, the exit pinch roller 7 is located below the steering roller 4, a plurality of rollers 8 are provided above the fixed platform 1, and the plurality of rollers 8 are linearly arranged with the conveyor belt 3 as the reference, the top surface of the support seat 2 is fixedly connected to two first fixed plates 9, the two entrance pinch rollers 6 are rotatably installed between the two first fixed plates 9, the top surface of the fixed platform 1 is fixedly connected to two second fixed plates 10, the two exit pinch rollers 7 are rotatably installed between the two second fixed plates 10, and the plurality of rollers 8 are rotatably installed between the two second fixed plates 10, the top surface of the fixed platform 1 is fixedly connected to two third fixed plates 11, the steering roller 4 is rotatably installed between the two third fixed plates 11, and the number of rollers 8 is four.

[0027] During specific implementation, the steel belt is pushed forward by the entrance pinch roller 6, and after turning at the turning roller 4, it is adsorbed on the bottom surface of the conveyor belt 3 by the air duct. The rotating conveyor belt 3 drives the steel belt to move. The conveyor belt 3 is made of soft material to avoid scratching the steel belt. The steel belt naturally droops after following the conveyor belt 3 for a distance. The roller 8 supports the steel belt. Because the contact area between the roller 8 and the steel belt is small and there is sliding friction, the scratch on the steel belt can be reduced. The exit pinch roller 7 drives the steel belt to continue to push forward. When the steel belt is stopped and started suddenly, the speed difference between the front and rear can naturally expand and contract between the entrance pinch roller 6 and the exit pinch roller 7, avoiding the wrinkle problem caused by the sudden stop and start of the thin steel belt when it is unwound.

[0028] See Figure 1 and Figure 2 The bottom of the support base 2 is fixedly connected to a drive motor 12, and the exhaust end of the fan 5 is connected to an air duct. The air duct is vertically flush with the bottom surface of the conveyor belt 3. The negative pressure air flow is extracted from under the conveyor belt 3 through the air duct, resulting in a decrease in the air pressure on the contact surface between the steel belt and the conveyor belt 3. The steel belt is tightly attached to the bottom surface of the conveyor belt 3 under the action of atmospheric pressure.

[0029] Example 2

[0030] The present invention provides a technical solution: a working method of an electroplated tin plate unwinding device with an anti-wrinkle function, comprising the following steps:

[0031] Step 1: The steel belt is pushed forward by the entrance pinch roller 6, and after turning at the turning roller 4, it is adsorbed by the air duct on the bottom surface of the conveyor belt 3. The rotating conveyor belt 3 drives the steel belt to move. The conveyor belt 3 is made of soft material to avoid scratching the steel belt. The steel belt follows the conveyor belt 3 for a distance and then naturally sags. The roller 8 supports the steel belt.

[0032] The outlet pinch roller 7 drives the steel strip to continue to push forward. When the steel strip stops or starts suddenly, the steel strip can naturally expand and contract between the inlet pinch roller 6 and the outlet pinch roller 7 due to the speed difference between the front and rear.

[0033] Working principle: The steel belt is pushed forward by the entrance pinch roller 6, and after turning at the turning roller 4, it is adsorbed on the bottom surface of the conveyor belt 3 by the air duct. The rotating conveyor belt 3 drives the steel belt to move. The conveyor belt 3 is made of soft material to avoid scratching the steel belt. The steel belt naturally droops after following the conveyor belt 3 for a distance. The roller 8 supports the steel belt. Because the contact area between the roller 8 and the steel belt is small and there is sliding friction, the scratches on the steel belt can be reduced. The exit pinch roller 7 drives the steel belt to continue to push forward. When the steel belt is suddenly stopped and started, the speed difference between the front and rear can naturally expand and contract between the entrance pinch roller 6 and the exit pinch roller 7, avoiding the wrinkle problem caused by the sudden stop and start of the thin steel belt when it is unwound.
