Granalladora de transportador de rodillos KNNJOO para tratamiento superficial continuo

Descripción de la granalladora de transportador de rodillos para tratamiento superficial continuo

Esta máquina es un equipo de limpieza por granallado de alto rendimiento tipo transportador de rodillos. Durante el proceso de limpieza, un motor regulador de velocidad acciona los rodillos transportadores para introducir la pieza en la zona de proyección de la cámara de limpieza. La pieza recibe el impacto concentrado de los cabezales de granallado desde distintas direcciones espaciales. Gracias al impacto y la fricción de los potentes proyectiles, la cascarilla de óxido y la suciedad se desprenden rápidamente, obteniendo la superficie del acero un acabado liso con una rugosidad determinada. Al mismo tiempo, la pieza recibe impactos intensos para eliminar sus tensiones internas y evitar su deformación.

Durante el proceso de limpieza, la mezcla de granalla y polvo dispersada se recoge en la carcasa inferior del elevador mediante el tornillo transportador de la cámara, y posteriormente se dirige al separador a través del elevador y el transportador. El separador genera una cortina de caída de granalla‑polvo y el polvo es eliminado por acción del flujo de aire. Los proyectiles limpios separados caen en la tolva del separador y son proyectados por el dispositivo de granallado a través del sistema de transporte de proyectiles.

El aire con polvo procedente del separador y de la cámara de limpieza es impulsado por el ventilador a través del sistema de conductos hacia el filtro de mangas para desempolvado, con una eficiencia de hasta el 99 %. El aire depurado se descarga a la atmósfera, mientras que las partículas de polvo quedan retenidas y recolectadas.

Tras el proceso de granallado, la pieza puede seguir cubierta por el medio abrasivo, el cual debe ser eliminado. La herramienta de limpieza de granalla es un cepillo giratorio fijado de forma rígida a un portacepillos intercambiable.

Para evitar que la granalla quede depositada sobre piezas largas, el cepillo giratorio retira suavemente el abrasivo usado de la superficie de la pieza y lo arrastra hacia una ranura de diseño especial. Dicha ranura está equipada con un tornillo transportador que devuelve el medio abrasivo para su reciclaje. Para mantener fija la posición del cepillo y del tornillo transportador durante el granallado de piezas de distintas dimensiones, ambos elementos se montan sobre un mismo bastidor regulable. El bastidor puede ajustarse de forma manual o automática dentro del rango de altura requerido, con una distancia de ajuste inferior a 5 mm. Finalmente, el medio residual sobre la pieza es eliminado por un soplador instalado en el mismo bastidor; un ventilador de alta presión se encarga de expulsar los restos de material.

Innovación: atreverse a romper con pensamientos rutinarios y malos hábitos, aprovechar nuevas ideas, enfoques y métodos, explorar espacios de innovación en tecnología, productos, servicios, gestión y mecanismos, para mantenerse siempre a la vanguardia del sector.

Superación: dejar atrás constantemente los éxitos pasados, fijar nuevos objetivos, explotar al máximo el potencial propio y desafiar los límites de la capacidad. No conformarse con la situación actual, tener el valor de ser pioneros, disfrutar del proceso de superarse a uno mismo y a los competidores, persiguiendo resultados más rápidos, sólidos y excelentes。


Q: Is the forklift industry ushering in a "super cycle"?

A: The industry data just released is too explosive! In October 2025, forklift sales 114,300 units, domestic and foreign sales soared by double digits (domestic sales + 16.2%, export sales + 15.4%), and the cumulative sales from January to October exceeded 1.22 million units, surging 14.2% year-on-year! On the one hand, JD.com spent 100 billion to purchase 3 million logistics robots, and on the other hand, hydrogen forklifts single order surged 108 units. The forklift industry is experiencing a "green + intelligent" dual revolution. These changes!

Q: How does a smart forklift work?

A: Have you seen how a smart forklift works? Recently, CCTV news came to Hefei and walked into the intelligent workshop of Anhui Forklift Group. Let's follow the camera. This 67-year-old enterprise is on a path of transforming and upgrading traditional industries and developing new quality productivity. Now I have come to the debugging and testing area of the mobile robot. More than a dozen cars behind me are conducting sensor calibration and basic function testing here. I am now standing on its forward path. In the eyes of the robot, I am an obstacle, and it will automatically stop.

Q: Smart Forklift "Create a new model of safety supervision?

A: According to the staff of Xinhe Food, the system integrates a number of intelligent management functions, and builds a comprehensive protection system through comprehensive digital control of personnel, vehicles and behaviors. The personnel management module realizes the digitization of the driver's account and real-time early warning; the vehicle positioning function ensures the safe operation of the forklift in the electronic fence; the operation early warning actively reminds to fasten the seat belt; the identification mechanism strictly restricts only the filing personnel to operate the vehicle, fundamentally eliminating unlicensed driving. At the same time, the system also has data analytics capabilities to provide reliable data support for vehicle scheduling and performance mangement.
