[0002] Corrosion foil is a key raw material for the production of aluminum electrolytic capacitors. Aluminum electrolytic capacitors have the characteristics of small volume, large capacitance and low cost. In particular, the price per unit capacitance is the cheapest among all capacitors, which conforms to the development trend of low-cost information products. At present, the output of aluminum electrolytic capacitors accounts for 45% of the total output of all capacitors, and is mainly used in household appliances such as computers, color TVs, air conditioners, cameras, VCDs, and numerically controlled lathes, among which the application in consumer electronic products accounts for 44%. Since 2010, the global production of capacitors has continued to grow, and electrolytic capacitors have maintained their position of accounting for one-third of the entire capacitor market.
[0003] In the existing corrosion foil production line, the aluminum foil is unrolled from the uncoiler, and the vehicle speed is controlled by the rotation speed of the asynchronous motor to drive the aluminum foil to move forward. Since the contact area between each roller and the aluminum foil is small, it is easy to cause slippage, and the unstable rotation speed of the asynchronous motor causes the vehicle speed to be unstable. It is necessary for the staff to adjust the vehicle speed many times, which increases the workload of the staff. At the same time, the aluminum foil is prone to deviation between the rollers, affecting the operation of the entire corrosion foil production line. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A constant speed device for a corrosion foil production line, including a bottom plate, the upper end surface of the bottom plate is fixedly connected with a roller frame, the inner side of the roller frame is rotatably connected with a main shaft and a sub-shaft located in front of the lower side of the main shaft, the outer walls of the main shaft and the sub-shaft are respectively fixedly connected with a main roller and a rubber roller, the left ends of the main shaft and the sub-shaft both extend to the outside of the roller frame and are respectively fixedly connected with a driving belt pulley and a driven belt pulley, a transmission belt is rotatably connected between the driving belt pulley and the driven belt pulley, a bracket is arranged between the main roller and the rubber roller, the left and right sides inside the bracket are both rotatably connected with upper pressure rollers, roller seats are arranged below the two upper pressure rollers, lower pressure rollers are rotatably connected inside the two roller seats, the left side wall of the bracket is fixedly connected with a sliding rod, the sliding rod is slidably connected with the roller frame, and a cylinder is installed on the right side wall of the roller frame, and the output end of the cylinder is fixedly connected with the right side wall of the bracket.
[0006] In order to make the lower pressing roller always move upward, as an optimization of the constant-speed device for an etched foil production line of the present utility model, a spring is fixedly connected between the roller seat and the bracket.
[0007] In order to enable the roller seat to move only in the vertical direction, as an optimization of the constant-speed device for an etched foil production line of the present utility model, two limit columns are fixedly connected to the bottom end of the roller seat, and the outer walls of the two limit columns are slidably connected with limit cylinders, and the other ends of the two limit cylinders are fixedly connected to the bracket.
[0008] In order to drive the main roller to move at a constant speed, as an optimization of the constant-speed device for an etched foil production line of the present utility model, an installation plate is fixedly connected to the upper left side of the bottom plate, a motor is installed on the outer wall of the installation plate, a speed reducer is installed inside the installation plate, and the output end of the motor is fixedly connected with the driving belt pulley through the speed reducer.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] The aluminum foil enters the production line from the foil uncoiler, then passes through the main roller and exits between the upper pressing roller and the lower pressing roller, and finally passes through the bottom of the rubber roller. The diameter of the main roller is 300 mm, which effectively increases the contact area between the aluminum foil and the main roller, enabling the aluminum foil to move stably on the line. When the motor is started, the output end of the motor passes through the speed reducer, thereby driving the main roller to rotate stably and uniformly. The rotation of the main roller drives the driving belt pulley to rotate, and the driving belt pulley further drives the driven belt pulley to rotate through the transmission belt, thereby driving the rubber roller to rotate, making the main roller and the rubber roller synchronous, facilitating the guiding of the aluminum foil, enabling the aluminum foil to move forward at a constant speed without slipping, eliminating the need for staff to repeatedly detect the rotation speed, and saving labor.
[0013] When the aluminum foil passes between the upper pressing roller and the lower pressing roller, the upper pressing roller and the lower pressing roller play a role in guiding and limiting, making the aluminum foil more stable and preventing deviation. When the air cylinder is started, it drives the entire bracket to move left and right. The other side of the bracket slides through the sliding rod and the roller frame, making the movement of the bracket stable. The bracket drives the upper pressing roller and the lower pressing roller on both sides to move left and right, thereby enabling fine adjustment of the aluminum foil and achieving the function of deviation correction, ensuring the normal operation of the aluminum foil production line.
