For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] The structure of a paste-making powder material processing system with automatic negative-pressure suction and automatic weighing provided by the present invention is as follows Figure 1 shown, including a dust large-material processing system 1 for processing large and small powder materials, a dust small-material processing system 2, a metering and paste-making system 3 for making paste from the powder materials processed by the dust large-material processing system 1 and the dust small-material processing system 2, and a dust removal system 4 for centrally removing the dust generated during the processing of the dust large-material processing system 1 and the dust small-material processing system 2.

[0030] When making paste, the dust large-material processing system 1 and the dust small-material processing system 2 are respectively used to unpack and suck the large and small powder materials. During the processing, the dust removal system 4 centrally removes the dust generated in the dust large-material processing system 1 and the dust small-material processing system 2. Finally, the sucked powder materials are weighed and made into paste by the metering and paste-making system 3.

[0031] Furthermore, as Figure 2 shown, the dust large-material processing system 1 includes a bag-unpacking mechanism 11 for unpacking, a screening mechanism 12 for screening and vibrating the large powder materials after unpacking by the bag-unpacking mechanism 11, a dust large-material bin assembly 13 for storing the large powder materials screened and vibrated by the screening mechanism 12, and a large-material vacuum negative-pressure pump 14 for automatically sucking the large powder materials in the screening mechanism 12 into the dust large-material bin assembly 13.

[0032] During implementation, the dust large-material is unpacked by the bag-unpacking mechanism 11, screened by the screening mechanism 12 after unpacking, and then the dust large-material in the screening mechanism 12 is sucked into the dust large-material bin assembly 13 by the large-material vacuum negative-pressure pump 14.

[0033] Furthermore, as Figure 2 and Figure 3 shown, the bag-unpacking mechanism 11 is composed of a bag-unpacking machine shell 111, a hoist 112, a transition buffer bin 113, a dual-channel bag-pressing assembly 114, and a flapping and squeezing assembly 115. The hoist 112 is installed at the top of the bag-unpacking machine shell 111, and the transition buffer bin 113, the dual-channel bag-pressing assembly 114, and the flapping and squeezing assembly 115 are arranged inside the bag-unpacking machine shell 111; the screening mechanism 12 includes a screening machine frame 121, a vibrating screen 122, a storage tank 123, and a dust collector 124. The vibrating screen 122 is installed at the top of the screening machine frame 121, and the vibrating screen 122 is connected to the transition buffer bin 113 through a pipeline. The bottom end of the vibrating screen 122 is communicated with the storage tank 123. The dust collector 124 is installed at the top end of the screening machine frame 121, and the air inlet end of the dust collector 124 extends into the vibrating screen 122.

[0034] During implementation, the large amount of powdered materials is lifted into the interior of the bag-breaking machine housing 111 by the elevator 112, patted by the patting and squeezing assembly 115, then bagged by the dual-channel bag-pressing assembly 114. Subsequently, the large amount of powdered materials falls into the interior of the transition buffer bin 113 and then falls into the vibrating screen 122 through a pipeline. The dust generated during the falling process is removed by the dust collector 124. After that, the large amount of powdered materials in the vibrating screen 122 enters the interior of the storage tank 123.

[0035] Furthermore, as Figure 4 shown, the dust small-material processing system 2 includes a bag-breaking mechanism 21 for bag breaking, a dust small-material bin assembly 22 for storing small powdered materials, a small-material vacuum negative-pressure pump 23 for automatically sucking the small powdered materials in the bag-breaking mechanism 21 into the dust small-material bin assembly 22, and a weighing and dosing mechanism 24 for automatically weighing the small powdered materials.

[0036] During implementation, the dust small materials are bag-broken by the bag-breaking mechanism 21. After bag-breaking, the dust small materials are fed into the dust small-material bin assembly 22 by the small-material vacuum negative-pressure pump 23, and then the dust small materials are dosed and weighed by the weighing and dosing mechanism 24.

[0037] Furthermore, as Figure 4 and Figure 5 shown, the bag-breaking mechanism 21 includes a placement seat 211, a manipulator 212, an air shower assembly 213, and an automatic bag-breaking machine 214. An air shower assembly 213 is installed on one side of the placement seat 211, and a manipulator 212 is arranged at the rear of the placement seat 211. The manipulator 212 is used to carry the small powdered material bags placed on the surface of the placement seat 211 into the air shower assembly 213. An automatic bag-breaking machine 214 for breaking the small powdered material bags is installed on one side of the air shower assembly 213, and the automatic bag-breaking machine 214 is connected to the feed port of the vacuum suction tank 5 in the dust small-material bin assembly 22 through a pipeline with a valve.

[0038] During implementation, the small powdered material bags are stacked on the surface of the placement seat 211. The manipulator 212 carries the small powdered material bags on the surface of the placement seat 211 into the air shower assembly 213, and then the automatic bag-breaking machine 214 is used for bag breaking. After bag-breaking, the small powdered materials enter the interior of the automatic bag-breaking machine 214.

[0039] Furthermore, as Figure 4 and Figure 6As shown in the figure, the weighing and feeding mechanism 24 is composed of a feeding frame 241, a transfer bin 242, a weighing scale 243, a feeder 244, and a suction machine 245. Several groups of feeders 244 are installed at the top of the feeding frame 241, and the suction machine 245 is connected to the top of the feeder 244. Moreover, the feed inlet of the suction machine 245 is connected to the discharge port of the powder bin 6 in the dust small bin assembly 22 through a pipeline. The weighing scale 243 is installed on the surface of the feeding frame 241 and is connected to the feeder 244, and the transfer bin 242 is arranged at the bottom of the weighing scale 243.

[0040] During implementation, the powder small material enters the interior of the feeder 244 through the suction of the suction machine 245, falls into the weighing scale 243 for weighing, and then enters the interior of the transfer bin 242 after weighing.

[0041] Furthermore, as Figure 1 and Figure 9 shown in the figure, several groups of dust large bin assemblies 13 and dust small bin assemblies 22 are provided. Both the dust large bin assembly 13 and the dust small bin assembly 22 are composed of a vacuum suction tank 5 and a powder bin 6. The vacuum suction tank 5 is installed at the top of the powder bin 6, and the feed inlet of the vacuum suction tank 5 is connected to the discharge ports of the storage tank 123 and the automatic bag breaker 214 through a pipeline with a valve. Moreover, the air outlet of the vacuum suction tank 5 is connected to the intake ends of the large bin vacuum negative pressure pump 14 and the small bin vacuum negative pressure pump 23 through a pipeline.

[0042] During implementation, the large bin vacuum negative pressure pump 14 or the small bin vacuum negative pressure pump 23 makes the vacuum suction tank 5 in the dust large bin assembly 13 or the dust small bin assembly 22 generate negative pressure through the connection of pipelines. When negative pressure is generated, the vacuum suction tank 5 will suck the large or small powder materials inside the storage tank 123 or the automatic bag breaker 214 through the pipeline and make them fall into the interior of the powder bin 6.

[0043] Furthermore, as Figure 7 shown in the figure, the metering and paste-making system 3 includes a metering mechanism 31 and a paste-making machine 32. The paste-making machine 32 is located on one side of the metering mechanism 31. The metering mechanism 31 is composed of a stirring and metering bin 311 and a vacuum suction tank 312. The vacuum suction tank 312 is installed at the top of the stirring and metering bin 311 and is connected to the stirring and metering bin 311. The discharge port of the stirring and metering bin 311 is connected to the feed inlet of the paste-making machine 32 through a pipeline and a feed pump. The feed inlet of the vacuum suction tank 312 is connected to the discharge port of the powder bin 6 in the dust large bin assembly 13 through a pipeline. The air outlet of the vacuum suction tank 312 is connected to the large bin vacuum negative pressure pump 14 through a pipeline. At the same time, the feed inlet of the vacuum suction tank 312 is connected to the transfer bin 242 through a pipeline.

[0044] During implementation, the large - material vacuum negative - pressure pump 14 will create a negative pressure in the vacuum - feeding material tank 312. After the vacuum - feeding material tank 312 has a negative pressure, it will suck the large - material powder in the powder bin 6 of the dust - large - material bin assembly 13 or the small - material powder in the transfer bin 242. After suction, it will enter the stirring and metering bin 311 for stirring and metering, and then be transported to the paste - making machine 32 by a feeder for paste - making.

[0045] Furthermore, as Figure 8 shown, the dust - removal system 4 is composed of a centralized dust - collector 41, a large - material dust hood 42, and a large - material dust hood 43. The large - material dust hood 42 is located above the dust - large - material processing system 1, and the large - material dust hood 43 is located above the dust - small - material processing system 2. Both the large - material dust hood 42 and the large - material dust hood 43 are connected to the intake end of the centralized dust - collector 41 through pipes.

[0046] During implementation, by the operation of the centralized dust - collector 41, the centralized dust - collector 41 uses pipes in cooperation with the large - material dust hood 42 and the large - material dust hood 43 to centrally remove dust at the dust - large - material processing system 1 and the dust - small - material processing system 2, avoiding dust pollution.

[0047] Working principle: When in use, the large - material powder is processed by the dust - large - material processing system 1. During the implementation of the dust - large - material processing system 1, first, the large - material powder is lifted to the inside of the bag - opening machine housing 111 by the elevator 112, patted by the patting and squeezing assembly 115, then bag - pressed by the dual - channel bag - pressing assembly 114. Subsequently, the large - material powder falls into the internal part of the transition buffer bin 113 and falls into the internal part of the vibrating screen 122 through a pipe. The dust generated during the fall is removed by the dust - collector 124. After that, the large - material powder inside the vibrating screen 122 enters the internal part of the storage tank 123. Finally, the large - material vacuum negative - pressure pump 14 creates a negative pressure in the vacuum - feeding tank 5 in the dust - large - material bin assembly 13 through the connection of pipes. When a negative pressure is generated, the vacuum - feeding tank 5 will suck the large - material powder inside the storage tank 123 through the pipe, causing it to fall into the internal part of the powder bin 6.

[0048] The small - material powder is processed by the dust - small - material processing system 2. First, the small - material powder bags are stacked on the surface of the placement seat 211. The manipulator 212 transports the small - material powder bags on the surface of the placement seat 211 to the air - shower assembly 213, and then the bags are broken by the automatic bag - opening machine 214. After bag - breaking, the small - material powder enters the internal part of the automatic bag - opening machine 214. Finally, the small - material vacuum negative - pressure pump 23 creates a negative pressure in the vacuum - feeding tank 5 in the dust - small - material bin assembly 22 through the connection of pipes. When a negative pressure is generated, the vacuum - feeding tank 5 will suck the small - material powder inside the automatic bag - opening machine 214 through the pipe, causing it to fall into the internal part of the powder bin 6. Then, the small - material powder inside the powder bin 6 enters the internal part of the feeder 244 under the suction of the suction machine 245, falls into the weighing scale 243 for weighing, and then enters the internal part of the transfer bin 242 after weighing.

[0049] After that, the large material vacuum negative pressure pump 14 will create a negative pressure in the vacuum suction material tank 312. After the vacuum suction material tank 312 has a negative pressure, it will suck the large powder material in the powder material bin 6 of the dust large material bin assembly 13 or the small powder material in the transfer bin 242. After suction, it will enter the mixing and metering bin 311 for mixing and metering, and then be transported to the paste making machine 32 by the feeder to complete the paste making work.

[0050] During the processes of the dust large material treatment system 1 and the dust small material treatment system 2 for treating the large powder material and the small powder material respectively, dust is often generated. At this time, the dust is centrally removed by the dust removal system 4. When the dust removal system 4 is implemented, it works through the central dust removal machine 41. The central dust removal machine 41 uses pipelines to cooperate with the large material dust hood 42 and the large material dust hood 43 to centrally remove the dust at the dust large material treatment system 1 and the dust small material treatment system 2, avoiding the phenomenon of dust pollution.

[0051] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claim.
