Description

Technical Field

[0001] The utility model relates to the technical field of food and drug packaging machinery and equipment, and particularly relates to a metering and conveying system. Background Art

[0002] In industries such as food, pharmaceuticals, health products, milk powder, and new energy, high-precision metering is an essential link in the batching process. Traditional high-precision metering is completed manually in a negative pressure weighing room, and the materials are manually fed into the system to achieve high-precision control of minor ingredients. This greatly reduces production efficiency, and due to the participation of personnel, it increases the risk of material contamination.

[0003] The existing utility model patent with the application number 202320123795.X discloses a powder feeding device with a weighing function, which fixedly connects a weighing device to the bottom of a mobile bin to weigh and package raw materials. It is difficult to accurately control the weight of the materials in the package, and it is difficult to achieve low-pollution conveying of the materials after weighing. Although the combination of a product conveying pipe and a vacuum feeding machine is used to realize the material conveying between a double-cone dryer and a double-source vibrating screen, it is only for raw material conveying and not for the packaging accuracy of the materials. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a metering and conveying system with high discharging accuracy, which can achieve low-pollution conveying of materials after metering and has no residue in the metering bin.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A metering and conveying system includes a feeding mechanism, a metering bin, and a material suction mechanism. The feeding mechanism is connected to the metering bin and is used to feed the metering bin. The material suction mechanism is arranged to be lifted and lowered and is used to extend into the metering bin to suck materials. The lowest position in the metering bin is provided with a bottom groove, and the bottom end of the material suction mechanism is provided with an adapter head that can extend to the bottom groove and be adapted to the bottom groove.

[0007] As a further improvement of the above technical solution:

[0008] The bottom groove is spherical, and the side wall of the end of the adapter head is provided with a groove.

[0009] The feeding mechanism is a vibrating feeding mechanism, and the vibrating feeding mechanism is located above the metering bin.

[0010] The metering bin includes a metering hopper, a weighing unit, and a vibrating unit. The metering hopper is connected above the weighing unit through a support unit, and the vibrating unit is arranged on the metering hopper.

[0011] The material suction mechanism includes a lifting pipeline and a vacuum material suction assembly, and the lifting pipeline is connected to the vacuum material suction assembly; a lifting pipeline driving mechanism can drive the lifting pipeline to extend into and withdraw from the metering bin.

[0012] The adapter head is arranged at the bottom end of the lifting pipeline.

[0013] The vacuum material suction assembly is located above the metering bin.

[0014] The metering and conveying system further includes a mounting frame, and the feeding mechanism, the metering bin and the material suction mechanism are all arranged on the mounting frame.

[0015] The mounting frame is provided with a valve connection mechanism, and the valve connection mechanism is connected to the feed inlet of the feeding mechanism.

[0016] A positioning unit is arranged on the mounting frame, the base of the transfer bin is detachably connected to the positioning unit, and the discharge port of the transfer bin is connected to the valve connection mechanism.

[0017] Compared with the prior art, the advantages of the present utility model are as follows:

[0018] In the metering and conveying system of the present utility model, the working process is as follows: the feeding mechanism supplies materials into the metering bin; when the materials in the metering bin reach a specified amount, the feeding mechanism stops feeding, and the material suction mechanism descends to extend the adapter head into the metering bin. The adapter head sucks materials while descending until it fits with the bottom groove, so that there is no material residue in the bin. On the one hand, after the materials are metered by the metering bin and the material suction mechanism and then discharged, the discharging accuracy is high, meeting the requirements of subsequent packaging accuracy; on the other hand, after the materials are metered, they are sucked and discharged by the material suction mechanism, so that the materials are conveyed in a closed environment inside the material suction mechanism, avoiding pollution of the materials during the conveying process, realizing low-pollution conveying after material metering, and leaving no residue in the metering bin.

[0028] Figures 1 to 3 An embodiment of the metering and conveying system of the present utility model is shown. The metering and conveying system of this embodiment includes a feeding mechanism, a metering bin 2, and a material suction mechanism 3.

The adapter head 33 sucks materials while descending until it fits with the bottom trough 4, ensuring no material residue in the bin. On the one hand, after material metering through the metering bin 2 and the suction mechanism 3, the discharging accuracy is high, meeting the subsequent packaging accuracy requirements; on the other hand, after material metering, the materials are sucked and discharged through the suction mechanism 3, enabling the materials to be transported in a closed environment within the suction mechanism 3, avoiding material contamination during transportation, achieving low-pollution transportation after material metering, and leaving no residue in the metering bin 2.

[0030] Further, in this embodiment, as Figure 3 shown, the bottom trough 4 is spherical, and a groove 331 is provided on the side wall at the end of the adapter head 33.

The metering hopper is connected above the weighing unit through a support unit, and the vibrating unit is arranged on the metering hopper. The bottom trough 4 is provided at the lowest position inside the metering hopper. The feeding mechanism is connected to the metering hopper to supply materials to the metering hopper. The weighing unit is used to weigh the materials in the metering bin 2 to control the accuracy of the material quantity in the metering bin 2. The vibrating unit is used to vibrate the metering bin 2 to facilitate residue-free discharging of the metering bin 2.

[0033] Further, in this embodiment, the suction mechanism 3 includes a lifting pipeline 31 and a vacuum suction component 32. The lifting pipeline 31 is connected to the vacuum suction component 32; the driving mechanism of the lifting pipeline 31 can drive the lifting pipeline 31 to extend into and withdraw from the metering bin 2. The driving mechanism of the lifting pipeline 31 can drive the lifting pipeline 31 to extend into and withdraw from the metering bin 2, which can not only extend into the metering bin 2 to suck materials while descending to improve the suction effect, but also withdraw from the metering bin 2 to facilitate the feeding of the metering bin 2.

[0034] Further, in this embodiment, the adapter head 33 is provided at the bottom end of the lifting pipeline 31.

[0035] Further, in this embodiment, the vacuum suction component 32 is located above the metering bin 2. This is convenient for arranging the lifting pipeline 31.

[0038] Specific process: The transfer bin 7 filled with materials is placed on the positioning unit on the mounting frame 5, and the discharge port of the transfer bin 7 is connected to the valve connection mechanism 6; the valve connection mechanism 6 is opened, and the materials fall into the feeding mechanism; the feeding mechanism supplies materials into the metering bin 2; when the materials in the metering bin 2 reach a specified amount, the feeding mechanism stops feeding, and the vacuum suction component 32 is turned on. The lifting pipe 31 descends to extend the adapter 33 into the metering bin 2. The adapter 33 sucks materials while descending until it fits with the bottom groove 4, so that there is no material residue in the bin; continue to suck materials until the weighing unit shows 0, and then stop sucking materials after a delay to empty the material residue in the pipe.
