Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of graphite felt purification, and particularly relates to an automatic feeding device for a continuous furnace carbonization furnace. Background Art
[0002] With the development of industrial technology, continuous furnaces have become the main production equipment for manufacturing various materials such as carbon felt and graphite felt. Continuous furnaces have the advantages of high efficiency and good flatness, and are widely used in the manufacturing process of these materials. During the production process of continuous furnaces, the processing method at the feeding end is crucial to the entire production process.
[0003] Currently, the main processing method at the feeding end of continuous furnaces still relies on manual operation: workers need to unroll and lay flat the raw materials in rolls (such as carbon felt or graphite felt) on a platform, and then the traction device at the discharging end of the continuous furnace introduces them into the furnace. This method has some obvious defects:
[0004] Manual participation is required: Manually unrolling raw materials is not only inefficient but also prone to errors. Especially on high-speed production lines, it is difficult to ensure the flatness of raw materials.
[0005] The raw materials are not unrolled in time: If the raw materials are not unrolled in time, the traction device at the discharging end of the continuous furnace may cause the soft felt to break due to excessive tension.
[0006] Overfeeding problem: If too much material is fed, it may cause the materials to stack up before entering the continuous furnace, thereby affecting the product quality and production efficiency.
[0007] In view of the above problems, the prior art urgently needs a device that can automatically feed materials, which can ensure the continuous and stable supply of materials during the unrolling process of the continuous furnace, thereby improving the production efficiency and finished product quality. Such a device should be able to automatically monitor the unrolling state of raw materials and start or stop the release of raw materials when necessary to avoid overfeeding or underfeeding. Content of the Utility Model
[0008] In order to make up for the above deficiencies, the utility model provides an automatic feeding device for a continuous furnace carbonization furnace, which avoids material stacking or breakage through the feeding process automatically controlled by starting and closing sensors, thereby improving the production efficiency and product quality.
[0009] The present utility model is realized through the following technical solutions: An automatic feeding device for a continuous furnace carbonization furnace, which is applied to a continuous furnace. The technical key points are as follows: A feeding platform is arranged at the inlet end of the continuous furnace; supports are arranged on the left and right sides near the front end of the feeding platform; a limit expansion shaft for fixing the coil material is arranged at the top of the support; a motor fixing frame is arranged outside one of the supports; a motor for driving the limit expansion shaft to rotate is fixedly arranged on the motor fixing frame; a start sensor for controlling the start of the motor is arranged in the middle of the support; a stop sensor for controlling the shutdown of the motor is arranged at the lower part of the support; a limit groove for placing the limit expansion shaft is arranged at the top of the support; the output shaft of the motor is connected to the limit expansion shaft through a coupling.
[0010] Further, the start sensor includes a start infrared receiver arranged on one of the supports and a start infrared transmitter arranged on the other support.
[0011] Further, the stop sensor includes a stop infrared receiver arranged on one of the supports and a stop infrared transmitter arranged on the other support.
[0012] Compared with the prior art, the beneficial effects and characteristics of the present utility model are as follows:
[0013] The automatic feeding device can automatically control the feeding process of the coil material without manual intervention, improving production efficiency. By controlling the start or stop of the feeding through the start sensor and the stop sensor, product quality problems caused by improper manual operation, such as material stacking or breakage, are avoided.
