Rotary dry powder packing machine

Abstract

The invention provides a rotary dry powder packing machine which comprises a rack, wherein a rotating shaft is rotatably mounted on the rack, a rotating cylinder is fixedly mounted on the rotating shaft, a plurality of annularly distributed packing devices are arranged uniformly at the bottom of the rotating cylinder, each packing device comprises a bag insertion starting device used for starting the whole set of the packing device after bag insertion, an automatic metering device used for weighing a packing bag, a sealing device used for sealing a discharge rubber tube after the last packing bag is packed, an automatic bag dropping return device used for automatically dropping the packing bag after the packing bag is packed, and a dust collection device used for processing the raised dust leaking from a dust discharge nozzle of the automatic bag dropping return device, and the bag insertion starting device, the automatic metering device, the sealing device and the automatic bag dropping return device are all electrically connected with a control system of the rotary dry powder packing machine. The rotary dry powder packing machine achieves automated packing production, is simple in operation and accurate in metering, simplifies the operation process, and also improves the production capacity and the working efficiency.

Description

technical field [0001] The invention relates to the technical field of dry powder production equipment, in particular to a rotary dry powder packaging machine. Background technique [0002] Dry powder packaging machine is a special equipment necessary for the production of bagged cement. It is used to complete the automatic packaging of cement, and can also be used to package other powdery materials with good fluidity (such as fly ash, cement additives, etc.). Most of the cement packaging machines are divided into fixed type and rotary type. The fixed type cement packaging machine refers to the packaging machine with 1-4 nozzles, and the filling of cement is completed by manually moving the bags. The rotary cement packaging machine refers to the 6-14 nozzles, which are manual The packaging machine does not move, and the packaging machine rotates to complete the bag filling. The rotary cement packaging machine is popular among cement manufacturers because of its high degree o...

AI Technical Summary

Problems solved by technology

The dry powder packaging machine in the prior art has the following defects: after inserting the bag, the travel switch must be lightly touched by hand, and after the control system receives the signal, the motor is started to start filling the material, the labor intensity of the workers is high, and the packaging efficiency is low

Due to the deformation of the angle iron after welding, and its own insufficient strength, it affects the measurement; the strain sensitivity of the sensor is poor, the elasticity and freedom of the spring piece are poor, and the measurement is inaccurate

The sealing form in the prior art is the sealing of the lower ram, and the traditional lower ram sealing device has many small mechanical parts, and the action is cumbersome. The sealing time of the device is short, and after a period of use, dust leakage or even dust spraying will occur

The existing bag drop return mechanism is often prone to non-return or even stuck phenomena during use. At the same time, the fast wear of the block and the frequent damage of the electromagnet lead to frequent glitches in the bag drop return mechanism.

In the prior art, the dust collector is connected to the bottom of the ash collecting hopper, and the dust collection effect is not ideal

In particular, the dust that comes out from the back of the ash nozzle cannot form a negative pressure due to the large dust removal space, and basically has no dust collection effect
