The unloading mechanism of tonnage bag comprises a carrying device and a unloading device. The carrying device is used to carry the tonnage bag and place the tonnage bag above the unloading device; The discharge device comprises a vertically arranged discharge cylinder, which comprises an outer cylinder and an inner cylinder arranged in a gap on the inner side of the outer cylinder; The upper end of the discharge cylinder forms the feed port of the discharge device, the lower end of the discharge cylinder forms the discharge port of the discharge device, and the feed port is directly opposite the bag port of the ton bag.
The loading device places the ton bag above the unloading device to facilitate the direct unloading of the ton bag; The discharge cylinder comprises an outer cylinder and an inner cylinder arranged in a gap on the inside of the outer cylinder, and the feeding port at the upper end of the discharge cylinder is opposite to the bag port of the ton bag; The bag mouth of the ton bag includes an inner bag mouth and an outer bag mouth. The inner bag mouth of the ton bag is placed in the inner cylinder, and the outer bag mouth of the ton bag is placed between the outer cylinder and the inner cylinder. The material in the ton bag is discharged from the inner bag mouth to the inner cylinder, and the dust is generated in the inner cylinder at the same time. When the dust diffuses outward along the gap between the inner bag and the inner cylinder, it enters between the outer cylinder and the inner cylinder; The outer cylinder and the outer bag mouth placed between the outer cylinder and the inner cylinder will block the dust and reduce its continued diffusion, and the dust will be deposited between the outer cylinder and the inner cylinder and finally discharged through the discharge port.
According to the tonnage bag discharge mechanism, the discharge cylinder is arranged as a double-layer structure of the outer cylinder and the inner cylinder, and the inner bag mouth is placed in the inner cylinder and the outer bag mouth is placed between the inner cylinder and the outer cylinder, so as to reduce the passage between the material in the tonnage bag and the outside world.
This reduces the outward diffusion of dust, effectively improves the working environment, and at the same time, the dust is deposited and reused, thereby reducing material loss.
