Rotary dry powder packaging machine

Abstract

The invention proposes a rotary dry powder packaging machine, which includes a frame, on which a rotating shaft is rotatably installed, on which a rotating drum is fixedly installed, and a plurality of annularly arranged packaging devices are uniformly arranged on the bottom of the rotating drum; each The packaging mechanisms all include: a bag-inserting start-up device for starting the entire packaging device after inserting the bag; an automatic weighing device for weighing the packaging bag; a sealing device for sealing the discharge hose after the previous packaging bag is packaged; After the packaging bag is packed, the automatic bag drop return device automatically drops the bag; the dust collection device used to deal with the dust leaked from the ash outlet of the automatic bag drop return device; the bag insertion start device, the automatic metering device, Both the sealing device and the automatic bag dropping and returning device are electrically connected to the control system of the rotary dry powder packaging machine. The rotary dry powder packaging machine realizes automatic packaging production, simple operation and accurate measurement, which not only simplifies the operation process, but also improves production capacity and work 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
