Automatic unloading device for ton bags

Abstract

The invention provides an automatic unloading device for ton bags. The device comprises a platform support, a bag grabbing mechanical hand, a material frame, a balancing weight, a frame releasing mechanism, a driving lever mechanism, a cam connection rod mechanism, a rocking arm vibration screen and a driving device. The rocking arm vibration screen and the driving device are installed on the platform support, the material frame is rotationally connected to the platform support, the bag grabbing mechanical hand is arranged on one side of the rocking arm vibration screen, the balancing weight is installed at the end of the material frame, the bottom face of the material frame is provided with a pressure sensor, the frame releasing mechanism is supported on the material frame, the frame releasing mechanism is connected with the driving lever mechanism, the pressure sensor is electrically connected with the driving lever mechanism through a controller, the driving device is connected withthe rocking arm vibration screen through the cam connection rod mechanism, the driving lever mechanism is in linkage with the frame releasing mechanism so as to enable the material frame to rotate around the platform support, and the ton bags are turned by 180 degrees after falling down to the rocking arm vibration screen. The automatic unloading device has the advantages that the material ton bags can be automatically turned upside down, materials are separated from bags, and the bags can be recycled without damage.

Description

Technical field: [0001] The invention belongs to the field of unloading devices, and in particular relates to an automatic unloading device for large bags. Background technique: [0002] In the process of material transfer in industrialized production, large-scale woven bags such as ton bags are widely used. Due to their large volume and high weight, unloading operations are more difficult. Manual cutting and other bag-breaking operations, this method causes the bottom or the whole of the material ton bag to be damaged and cannot be reused. The material ton bag can only be recycled as waste material and sold at a low price. Some companies also use hooks or hooks for the lifting belt of the material ton bag The buckle is fixed, otherwise the material ton bag will fall off together with the material, and then use a rotary forklift or a similar device to cooperate with the dumping operation. This method is cumbersome and inefficient, and the vehicles are cross-operated, so the ...
