Descripción de la máquina granalladora de rodillos para tratamiento continuo

La máquina granalladora de paso por rodillos presenta excelentes prestaciones funcionales. El equipo transporta la estructura de acero o piezas de acero hasta la zona de proyección dentro de la cabina de limpieza mediante rodillos transportadores controlados eléctricamente con velocidad regulable. En el interior del equipo, potentes granallas procedentes de distintas direcciones impactan y frotan la superficie del acero, eliminando la escama de óxido, capa de herrumbre y manchas presentes sobre la pieza. Tras el tratamiento, la superficie del acero queda más uniforme. Las piezas procesadas se descargan a través de los túneles de limpieza situados en las entradas y salidas exteriores de ambos lados.

La máquina granalladora de paso por rodillos se utiliza principalmente para la limpieza y endurecimiento superficial de soldaduras de estructuras metálicas, vigas H, chapas de acero y otros materiales de acero. Sus sectores de aplicación habituales son automoción, tractores, motores y válvulas. Este equipo permite limpiar rápidamente la superficie de las piezas, mejorar su acabado y, consecuentemente, incrementar la calidad del recubrimiento, por lo que es muy demandado en numerosas industrias de transformación.

Tras el proceso de granallado del equipo de limpieza por granalla, la pieza puede permanecer cubierta de granallas, las cuales deben eliminarse. La herramienta de limpieza de granallas es un cepillo giratorio fijado firmemente sobre un portacepillo intercambiable.

Dispositivo de limpieza de granallas

Para evitar que las granallas permanezcan sobre piezas largas, el cepillo giratorio barre suavemente el abrasivo usado de la superficie de la pieza y lo dirige hacia una ranura diseñada especialmente. La ranura está equipada con un transportador de tornillo para devolver el medio abrasivo y permitir su reciclaje. Para mantener fija la posición del cepillo y el transportador de tornillo durante el granallado de piezas de diferentes dimensiones, ambos elementos se montan sobre el mismo bastidor regulable. El bastidor se puede ajustar de forma manual o automática dentro del rango de altura requerido; la distancia de regulación debe ser inferior a 5 mm. Finalmente, el medio abrasivo residual sobre la pieza se elimina mediante un soplador montado en el mismo bastidor, que utiliza un ventilador de alta presión para expulsar los residuos.

Carga y descarga

En el equipo básico, la entrada y la salida del transportador de rodillos son accionadas por el motor central de la máquina granalladora. Para mejorar la eficiencia, se puede instalar una unidad de accionamiento independiente, y el variador de frecuencia asociado se sincroniza automáticamente. Si las piezas curvas tras el granallado no pueden limpiarse completamente mediante el cepillo giratorio y el soplado, se recomienda utilizar una vía de recogida y un transportador de reciclaje más largos para garantizar que el equipo recupere todas las granallas.

La instalación de un sistema de alimentación horizontal permite mejorar la eficiencia en múltiples aspectos. Este sistema se puede integrar junto con la máquina granalladora en líneas de producción de serrado o taladrado. La mayoría de las máquinas granalladoras de transportador de rodillos utilizan granallas redondas (granalla de acero fundido o granalla de acero cortada redondeada). Las granallas circulan por el interior del equipo y eliminan continuamente los contaminantes superficiales.

Para conseguir un buen resultado de granallado, es indispensable mantener una mezcla equilibrada entre granallas nuevas y usadas. Las granallas finas de la mezcla garantizan una cobertura uniforme sobre la superficie de la pieza, mientras que las granallas gruesas son fundamentales para eliminar la escama de óxido. El empleo del tipo correcto de granalla es especialmente importante para garantizar un rendimiento óptimo del proceso de granallado.

Guía de uso

  • Piezas con mecanizado en bruto (perfiles de placas gruesas): utilizar mezcla de granalla gruesa (tamaño S390 o superior).

  • Piezas para acabado superficial (láminas metálicas delgadas): utilizar mezcla de granalla fina (tamaño S330 o inferior).

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.
