Material packer

Abstract

The invention discloses a material packer, which comprises a plurality of material bins arranged along the height direction. The material bins can be sequentially communicated in a disconnected manner, each material bin is provided with a closeable first air inlet capable of leading air into the material bin, the top material bin is provided with a closeable feeding port capable of conveying materials into the material bin, the bottom material bin is internally provided with a second air inlet capable of fluidizing the materials and a closeable discharging port, and the fluidized materials can be conveyed out of the inside of the material bin through the discharging port so as to be packed. Along with packing of the materials, the vacant material bins can be gradually disconnected from top to bottom, so that the residual space inside the packer cannot be gradually increased. Therefore, material packing is accelerated, serious separation of the mixed materials of different grain sizes can be effectively avoided, and the material packer is particularly applicable to packing mixed material products such as dry-mixed mortar and the like.

Description

technical field [0001] The invention relates to the field of material packaging, in particular to a material packaging machine, which is an air blowing material packaging machine. Background technique [0002] The material packaging machine is widely used in the material packaging process in various fields. At present, the common material packaging machines are mainly air blowing packaging machines. This kind of air blowing packaging machine mostly adopts a single silo structure, such as figure 1 As shown, when the packaging machine is feeding, the feeding butterfly valve 1' and the exhaust butterfly valve 2' are opened, the control valve on the discharge port 5' is closed, the gas system 4' does not carry out gas transmission, and the material passes through the feeding butterfly valve 1' Enter the material bin 3'; when the feeding is completed, the feeding butterfly valve 1' and the exhaust butterfly valve 2' are closed, and the gas system 4' starts to deliver gas to the...

Problems solved by technology

This increases the time taken to deliver the gas, which in turn reduces the speed of packaging

[0005] 2. When the material in the material bin gradually decreases, the empty space of the material bin increases. If the packaged material is a mixed material composed of materials with different particle sizes such as dry-mixed mortar, it will cause the material to collapse under the action of air force. Serious segregation phenomenon occurs, that is, the original mixing ratio of materials with different particle sizes will be destroyed under the action of air flow, which will cause various problems in the next use of materials, such as the quality of dry-mixed mortar will decrease in subsequent use, which cannot meet the requirements Engineering needs
