Detailed Description

In order to facilitate an understanding of the invention, the invention will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of the invention is not limited to the specific embodiments below.

It should be particularly noted that when an element is referred to as being "fixed to, connected to or communicated with" another element, it can be directly fixed to, connected to or communicated with the other element or indirectly fixed to, connected to or communicated with the other element through other intermediate connecting components.

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.

Example 1

The cement packaging device shown in fig. 1 comprises a circular metering bin 1, a manual switch valve 2, a conveying table conveying device 5, a vacuum pump 6 and a negative pressure conveying pipeline 7, and further comprises an automatic metering valve 3 and a heat sealing device 4 (4); the negative pressure conveying pipeline 7 is communicated with the circular metering bin 1; an output pipeline is arranged at the lower part of the circular metering bin 1, and the manual switch valve 2 and the automatic metering valve 3 are arranged on the output pipeline; the conveying table conveying device is located below the output pipeline. In the invention, the automatic metering valve 3 can measure the flow of the cement powder, thereby measuring the packaging amount of the cement, and being very convenient; when the manual switch valve 2 is opened, the cement powder flows out from the output pipeline and flows into the packaging belt; when the cement amount in the packaging belt reaches the requirement, the automatic metering valve 3 is closed, the discharging is stopped, and after the sealing and the replacement of the overhead packaging bag 8 are completed, the automatic metering valve 3 is reopened. When the materials are loaded, the packaging bags are placed on the conveying table conveying device, the seal is opened, and the output pipeline extends into the packaging bags.

In this embodiment, the conveying table transporting device 5 is arranged on the weighing table; the weight sensor of the weighing platform is connected to the PLC, and the automatic metering valve 3 is also connected to the PLC. In this embodiment, the weight measured by the weighing platform and the weight measured by the automatic metering valve 3 are compared by the PLC, and when the difference between the two is within 0.5 kg, the process is determined to be normal, otherwise, the process is stopped and an alarm is given, and a worker needs to start to process the process, which indicates that the metering is in a problem and needs to perform troubleshooting.

In this embodiment, the output pipeline is a telescopic pipeline, and the switching valve and the automatic metering valve 3 are arranged at the upper part of the output pipeline; the lower part of the output pipeline can be telescopic. That is to say, in this embodiment, the output pipeline can stretch out and draw back only under the on-off valve and the automatic metering valve 3, so that the stretching out and drawing back of the output pipeline does not affect the on-off valve and the automatic metering valve 3. The output pipeline can stretch out and draw back mainly can reduce the production of dust with the inside of output pipeline's flexible wrapping bag 8 as far as possible, after contracting output pipeline into simultaneously, makes things convenient for sealing device 4 to carry out the pyrocondensation to wrapping bag 8 and seals.

In this embodiment, the lower part of the circular metering bin 1 is provided with 2, and the two output pipelines are provided with a manual switch valve 2 and an automatic metering valve 3. Two or more output pipelines are arranged to mainly accelerate the discharging efficiency.

In this embodiment, the heat sealing device 4 includes two heating blocks arranged oppositely; the heating block is arranged on the horizontal rail 10, and a wrench 11 which is closed or opened is arranged on the heating block. When the heat sealing is not needed, the two heating blocks are separated by the wrench 11, and in this time, the heating power of the heating blocks is reduced, so that the energy waste is prevented, and meanwhile, the scalding is prevented; the heating power of the heating block is increased when the heating block is closed, so that heat sealing is performed. When the heat-seal, two output pipeline upwards shrink, have enough space like this and make the heating block carry out hot-blastly to 8 mouths of wrapping bag, in this embodiment, the sack of wrapping bag 8 adopts plastic-aluminum membrane 9, can seal like this under the circumstances of heating.

Carry circular measuring storehouse 1 with cement through vacuum pump 6, there are two or a plurality of output pipeline circular measuring storehouse 1 downside, and from the top down is provided with hand switch valve 2 and automatic metering valve 3 respectively on the pipeline, all can control alone, and wherein automatic metering valve 3 can the real time monitoring cement powder's velocity of flow, flow isoparametric to the realization is to controlling of whole conveying efficiency. The cement packaging bag 8 is sealed by adopting a material easy to be heat-sealed, such as an aluminum plastic film 9, and after the cement packaging bag is packaged, the packaging bag is subjected to heat sealing treatment. And conveying the packaged bagged cement to the next working procedure through a conveying platform.
