Description

Technical Field

[0001] This utility model relates to the field of loss-in-weight measurement technology, specifically a quantitative feeding type loss-in-weight measurement device. Background Technology

[0002] Loss-in-weight metering devices are equipment that achieves accurate measurement by monitoring changes in the weight of materials in real time. They are widely used in industrial production scenarios that require continuous, stable, and accurate feeding (such as the chemical, food, pharmaceutical, and building materials industries). For example, in prior art 1 (Chinese patent application number CN202421550891.3, application date 2024-07-03), a loss-in-weight scale metering chamber uses a hinge, a rotating plate, and a handle. When material needs to be added, simply pull the handle, and the rotating plate will rotate around the hinge as the axis of rotation, thereby opening the rotating plate for material addition. This design can prevent dust and impurities from entering the metering chamber and also facilitate material addition.

[0003] While existing technologies can facilitate convenient feeding to improve the usability of loss-in-weight metering devices, they still require manual operation, which increases the workload of staff and reduces feeding efficiency, resulting in poor practicality. Therefore, a quantitative feeding type loss-in-weight metering device has been proposed to effectively solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a quantitative feeding type loss-in-weight metering device to solve the problem mentioned in the background art that the current loss-in-weight metering devices on the market require manual operation for feeding, which not only increases the workload of the staff, but also reduces the feeding efficiency of materials and has poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative feeding loss-in-weight metering device, comprising a machine body and a variable frequency motor disposed above the machine body, wherein the output end of the variable frequency motor is connected to an auger conveying rod, and the auger conveying rod is disposed inside a discharge pipe; a storage bin is installed above the machine body, and a discharge pipe is disposed below the storage bin, and a discharge pipe is sealed and connected below the discharge pipe; a cover plate is disposed above the storage bin, and a feed pipe is sealed and installed above the cover plate; a movable frame is slidably installed inside the storage bin, and a plug is installed above the movable frame, with a feed pipe corresponding to the top of the plug.

[0006] Preferably, a positioning frame is installed inside the storage bin, and a drive motor is installed above the positioning frame, with the output end of the drive motor connected to a rotating shaft.

[0007] Preferably, a mounting bracket is connected above the rotating shaft, and two first electromagnets are mounted above the mounting bracket, with the two first electromagnets arranged symmetrically about the vertical center line of the mounting bracket.

[0008] Preferably, a second electromagnet is positioned above each of the two first electromagnets, and a ring of second electromagnets is arranged at equal intervals below the movable frame, wherein the first electromagnets and the second electromagnets have the same magnetic poles.

[0009] Preferably, the storage bin is provided with two return springs, and the two return springs have the same structure, and the other side of the two return springs is connected to a movable frame.

[0010] Preferably, a row of stirring rods is installed on the outer side of the rotating shaft, and the row of stirring rods is arranged at equal intervals inside the storage bin.

[0011] Preferably, the outer side of the rotating shaft is connected to two cleaning scrapers via a connecting frame, wherein the two cleaning scrapers are fitted into the inner wall of the storage bin.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) A plug is provided. A movable frame is slidably installed inside the machine body, and a plug is installed on the top of the movable frame. When feeding is required, the movable frame can be moved back and forth to allow the plug on the top of the movable frame to block the material from the feed pipe. This allows for intermittent quantitative feeding of the material conveyed by the feed pipe, avoiding the material being directly conveyed into the machine body and affecting the storage of the material later. This makes it more practical.

[0014] (2) A mounting frame is provided. When it is necessary to intermittently and quantitatively feed the feed pipe, simply start the drive motor to drive the mounting frame connected above the rotating shaft to rotate. At this time, the two first electromagnets set above the mounting frame will drive the moving frame to move upward through the principle of magnetic repulsion between like poles of the moving frame. This will cause the plug set above the moving frame to block the feed pipe from feeding, thereby stopping the feeding.

[0015] (3) Furthermore, after the two first electromagnets set on the mounting frame are separated from the moving frame installed below the moving frame, the two reset springs will use their own elastic force to move the moving frame down after it has been squeezed and moved upward, so that the plug set on the top of the moving frame is separated from the feed pipe. At this time, the feed pipe can be opened to feed the material, thus realizing the intermittent quantitative feeding of the material.

[0016] (4) A stirring rod is provided. When the drive motor drives the rotating shaft to rotate the mounting frame, the rotating shaft will simultaneously drive a row of stirring rods that are meshed on its outer side to rotate and mix in the storage bin. This will achieve mixing and stirring of the materials stored in the storage bin, avoid the phenomenon of sedimentation and clumping in the storage bin, and improve the storage efficiency of the materials.

[0017] (5) Furthermore, while the rotating shaft drives a row of stirring rods to reciprocate and mix inside the storage silo, the connecting frame connected to both sides of the rotating shaft will also drive two cleaning scrapers to clean and scrape the material residues adhering to the inner wall of the storage silo in a cyclical manner, so as to avoid the material residues remaining on the inner wall of the storage silo and affecting the later material storage and use, thereby improving the storage efficiency of the storage silo for materials.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution: a quantitative feeding type loss-in-weight metering device:

[0027] Example 1: To address the problem that existing loss-in-weight metering devices require manual feeding, which increases the workload of operators and reduces material feeding efficiency, resulting in poor practicality, the following invention is disclosed: a machine body 1, and a variable frequency motor 2 mounted on top of the machine body 1. The output end of the variable frequency motor 2 is connected to an auger conveyor rod 8, which is located inside a discharge pipe 7. A storage bin 3 is installed above the machine body 1, and a discharge pipe 6 is located below the storage bin 3. The discharge pipe 7 is sealed to the bottom of the discharge pipe 6. A cover plate 4 is installed above the storage bin 3. Figure 1 As shown, a feed pipe 5 is sealed and installed above the cover plate 4, a movable frame 15 is slidably installed inside the storage bin 3, a plug 17 is installed above the movable frame 15, and a feed pipe 5 is correspondingly installed above the plug 17.

[0028] A positioning frame 9 is installed inside the storage bin 3, and a drive motor 10 is installed above the positioning frame 9. The output end of the drive motor 10 is connected to a rotating shaft 11, and a mounting frame 18 is connected above the rotating shaft 11. Two first electromagnets 19 are installed above the mounting frame 18, and the two first electromagnets 19 are symmetrically arranged about the vertical center line of the mounting frame 18. A second electromagnet 20 is positioned above the two first electromagnets 19. A ring of second electromagnets 20 is evenly spaced below the moving frame 15. The first electromagnets 19 and the second electromagnets 20 have the same magnetic poles. Figure 4 and Figure 5 As shown, the storage bin 3 is equipped with two return springs 16 inside, and the two return springs 16 have the same structure. The other side of the two return springs 16 is connected to a movable frame 15.

[0029] When quantitative feeding of materials is required, simply start the drive motor 10 to rotate the mounting bracket 18 connected above the rotating shaft 11. Figure 3As shown, at this time, the two first electromagnets 19 set above the mounting frame 18 and the ring of second electromagnets 20 set below the moving frame 15 will drive the moving frame 15 to move upward through the principle of magnetic repulsion, so that the plug 17 set above the moving frame 15 will block the feeding pipe 5 to stop the feeding. After the two first electromagnets 19 set above the mounting frame 18 separate from the moving frame 15 installed below the moving frame 15, as Figure 4 and Figure 5 As shown, the two return springs 16 can use their own elastic force to move the moving frame 15 downward after it has been squeezed and moved upward, so that the plug 17 set above the moving frame 15 is separated from the feed pipe 5. At this time, the feed pipe 5 can be opened to feed the material, which can realize the intermittent quantitative feeding of the material and improve its practicality.

[0030] The material is then conveyed through the discharge pipe 6 to the inside of the discharge pipe 7. At this time, the variable frequency motor 2 is started to drive the auger conveyor rod 8 to rotate inside the discharge pipe 7, so that the rotating auger conveyor rod 8 discharges the material through the discharge pipe 7. Figure 1 and Figure 2 As shown, this provides better assistance for material feeding.

[0031] Example 2 differs from Example 1 in that, while the loss-in-weight metering device assists in feeding, it can simultaneously drive two cleaning scrapers 14 to circulate and scrape the material residue adhering to the inner wall of the storage bin 3. This prevents material residue from adhering to the inner wall of the storage bin 3 and affecting subsequent storage processing, thus improving the practicality of the loss-in-weight metering device. The following is disclosed:

[0032] A row of stirring rods 12 is installed on the outer side of the rotating shaft 11, and the row of stirring rods 12 are evenly spaced inside the storage silo 3. Two cleaning scrapers 14 are connected to the outer side of the rotating shaft 11 through a connecting frame 13, and the two cleaning scrapers 14 are attached to the inner wall of the storage silo 3 (e.g., Figure 3 and Figure 6 (As shown).

[0033] While the drive motor 10 drives the rotating shaft 11 to rotate the mounting bracket 18, the rotating shaft 11 simultaneously drives a row of stirring rods 12, which are meshed with its outer side, to reciprocate and mix inside the storage bin 3. Figure 4 As shown, this system is designed to mix and stir the materials stored inside the storage silo 3, preventing sedimentation and clumping. While the rotating shaft 11 drives a row of stirring rods 12 to reciprocate and mix inside the storage silo 3, the connecting frames 13 on both sides of the rotating shaft 11 simultaneously drive two cleaning scrapers 14 to circulate and scrape away any material residue adhering to the inner wall of the storage silo 3. Figure 6As shown, this avoids material residue on the inner wall of the storage bin 3, which would affect the subsequent storage and use of materials, and improves the storage efficiency of the storage bin 3.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
