The shaping device is also called a forming device, and is used for integrating the materials in the open bag filled by the filling machine into a rectangular shape under a vibration state, so that the materials are convenient to stack and are not easy to collapse in logistics links such as storage and transportation.
The aforementioned open bag is widely used for packaging of powder or granular materials such as fine chemical raw materials such as ultrafine powders, metal ore and non-metal ore powders, pharmaceutical chemical raw materials, dyes, pigments, calcium carbonate, kaolin, phenol resins, and even flours, seasonings in the food seasoning category. Open-bag filling machines are widely used in the industry not limited to the aforementioned products, because of their advantages of high filling efficiency, accurate metering, low labor input, and contribution to significantly reducing the working intensity of workers and improving the environment of the filling work site.
An open-bag filling machine set typically comprises: the automatic quantitative weighing device is an automatic quantitative scale, a bag warehouse, an automatic bag feeding device, an automatic bag clamping device, an automatic bag opening clamping device, an automatic discharging device, an automatic bag beating device, an automatic conveying and loading trolley, an automatic bag opening sealing device and the like. The action process of the devices is as follows: the automatic quantitative weighing device quantitatively weighs, the bag warehouse automatically provides empty open bags to be filled, the automatic bag loading device automatically extracts an empty open bag and feeds the extracted empty open bag to the automatic clamping device, the automatic clamping device clamps two sides of the bag opening, materials to be weighed by the automatic quantitative weighing device are introduced into the open bag through the discharging device and then are patted by the automatic bag patting device, so that air mixed in the materials is discharged and the materials are compacted, the filled open bags are clasped by the automatic bag clasping device and are sent to the automatic sealing device, and the bags are sealed by the automatic sealing device.
Technical information relating to an open-pocket filling machine is not known in the published chinese patent documents, and examples thereof are ZL201620205588.9 (bag clamping device of an open-pocket automatic filling machine), ZL201620206148.5 (discharging device of an open-pocket automatic filling machine), ZL201620205835.5 (open-pocket automatic bag holding device), ZL20182162935.2 (bag beating mechanism of a packing machine), ZL201821669780.8 (open-pocket automatic discharging device having a function of sealing an air-inflated bag opening), ZL201821669993.7 (vacuum pumping mechanism of an open-pocket automatic discharging device), ZL201822178209.3 (internal and external combined dust removing device of an open-pocket full automatic filling machine), ZL201920116357.4 (dust suction device of an open-pocket filling machine), and ZL201920342830.0 (automatic clamping device of an open-pocket filling machine), and the like.
