Technical Field
[0001] The utility model relates to the technical field of frequency converters, and specifically to a frequency conversion device for a high-speed wrapping machine of fire-resistant mica tape. Background Art
[0002] The frequency conversion device of the wrapping machine is an electronic device used to control and adjust the motor speed of the wrapping machine. This device enables users to adjust the working speed of the wrapping machine according to needs to meet different wrapping requirements. Specifically, the device can control the tension and speed of the wrapping wire by changing the frequency of the motor of the wrapping machine, thereby realizing an efficient and stable production process.
[0003] Although the frequency conversion device of the wrapping machine brings many benefits in improving production efficiency and quality, there are still the following deficiencies: the frequency conversion device of the wrapping machine needs to work at a relatively low temperature and relative humidity, and requires conditions such as dust prevention, shock prevention, and corrosion prevention. These requirements pose high demands on the production environment, which is the problem to be solved by the present utility model. Content of the Utility Model
[0004] The purpose of the present utility model is to provide a frequency conversion device for a high-speed wrapping machine of fire-resistant mica tape to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: A frequency conversion device for a high-speed wrapping machine of fire-resistant mica tape, including a box body, a first pipeline, a radiator, a third pipeline, and a second pipeline. A partition is fixedly arranged in the middle of the interior of the box body. A first cavity is arranged at the top of the partition, and a second cavity is arranged at the bottom of the partition. A motor is fixedly arranged in the middle of the interior of the first cavity. A frequency converter is arranged at the top of the motor. The surfaces of both the frequency converter and the motor are wound with the second pipeline. One end of the second pipeline is connected to one end of the first pipeline through a first connector, and the other end of the second pipeline is connected to one end of the third pipeline through a second connector.
[0006] When using the frequency conversion device for a high-speed wrapping machine of fire-resistant mica tape in this technical solution, the staff starts the radiator, and the pump body installed in the radiator will pump and circulate the cooling liquid in the first pipeline, the second pipeline, and the third pipeline. When the liquid flows into the interior of the second pipeline, it will take away the heat dissipated by the running motor. When the liquid containing heat flows back into the interior of the radiator through the third pipeline, the liquid will enter the pipeline connected to the heat dissipation fins, and the fan will blow air on the heat dissipation fins to achieve active water-cooled heat dissipation. The heat-dissipated liquid will be pumped back into the interior of the first pipeline by the pump body again, and then be transmitted to the interior of the second pipeline through the first pipeline to continue water-cooled heat dissipation for the motor.
[0007] Preferably, the other end of the first pipe is connected to the outer side of the radiator, and the radiator is fixed inside the second cavity. The other end of the third pipe is connected to the other outer side of the radiator. Through the cooperation of the first pipe and the third pipe, the cooling liquid in the second pipe can be communicated with the radiator and circulated, achieving the effect of communicating and circulating the cooling liquid.
[0008] Preferably, a pump body, heat dissipation fins and a fan are provided inside the radiator. By providing the radiator, the cooling liquid circulated in the first pipe, the second pipe and the third pipe and the heat contained therein can be pumped and dissipated, achieving the effect of pumping and circulating the cooling liquid and dissipating heat.
[0009] Preferably, heat dissipation holes are provided on both sides inside the box body. The heat dissipation holes adopt a vertical and inclined structure design. Such a design facilitates the entry of external gas into the box body, but it is not easy for sundries to enter and they are easy to slide out.
[0010] Preferably, a box door is rotatably installed on the front surface of the outer part of the box body, and a fixed lock is embedded at one end of the box door. The installation of the box door enables the staff to rotate and open it to perform maintenance and other operations on the equipment installed inside the box body, providing an operating position, while the installation of the fixed lock prevents the box door from being opened by unauthorized personnel.
[0011] Preferably, the second pipe is specifically a flexible heat-conducting pipe, and the first pipe and the third pipe are specifically made of stainless steel. The flexible heat-conducting pipe uses materials such as silica gel, graphite, and asbestos as heat-conducting media, and the outer shell is made of flexible materials such as polyimide and fluoroplastics. It has the advantages of good heat-conducting performance, strong flexibility, high temperature resistance, and corrosion resistance, while the first pipe and the third pipe made of stainless steel have the advantages of corrosion resistance, high temperature resistance, and high strength.
[0012] Compared with the prior art, the beneficial effects of the present utility model are:
[0013] 1. The second pipe of the present utility model is wound on the surfaces of the motor and the frequency converter, and the first pipe and the third pipe cooperate with the radiator to circulate the internal cooling liquid, so that the motor and the frequency converter can be cooled, improving the heat dissipation efficiency. Moreover, the heat dissipation holes provided on both sides of the box body adopt an inclined structure, which can assist in cooling the motor and prevent sundries from entering the box body.
