Description

Technical Field

[0001] This utility model relates to the field of industrial automation equipment, and in particular to a feeding mechanism. Background Technology

[0002] A feeder (also known as a material handling machine) is a device used for material conveying, mainly used to transport materials to be processed to the main equipment for processing.

[0003] In the prior art, such as the hydrogen crushing furnace charging car disclosed in Chinese Utility Model Patent (Announcement No.: CN216736066U), the structure includes a mobile charging car body. The charging car body is provided with a hopper, an inlet and an outlet respectively connected to the hopper. A spiral feeding rod corresponding to the outlet is provided in the hopper. The spiral feeding rod is used to transfer the material falling into the hopper to the outlet. The charging car body is also provided with a motor. The output end of the motor is connected to the spiral feeding rod through a reducer. One end of the spiral feeding rod extends into the outlet pipe, and the other end of the spiral feeding rod is rotatably connected to the charging car body through a bearing assembly. The feeding vehicle has a screw feeding rod installed in the hopper of the feeding vehicle body that corresponds to the discharge port, and a motor for driving the screw feeding rod to operate. During the operation, when feeding the hydrogen crushing furnace cylinder, the motor drives the screw feeding rod to rotate through the reducer, so that the screw blades of the screw feeding rod uniformly and stably transport the sheet material in the hopper to the discharge port, and then enter the cylinder through the discharge port.

[0004] However, the hydrogen crushing furnace feeding cart disclosed in the above-mentioned prior art has the following defects: ① The output end of the motor is connected to the screw feeder via a reducer, and one end of the screw feeder is rotatably connected to the feeding cart body via a bearing assembly, making it impossible to form an effective seal at the connection between the screw feeder and the feeding cart body; ② The feeding cart body is detachably connected to a cover plate for covering the feed inlet, but no sealing structure is provided between the cover plate and the feeding cart body, making it impossible to seal the feed inlet. In summary, this feeding cart cannot meet the feeding requirements of materials with high sealing requirements (such as titanium alloy powder).

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a feeding mechanism that achieves contactless transmission through a motor, eliminating the problem of poor airtightness caused by the shaft hole in traditional mechanical seals; its hopper is equipped with a valve to achieve sealing at the hopper, enabling the feeding mechanism to meet the feeding needs of materials with high sealing requirements.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A feeding mechanism includes a mechanism body, which includes a feeding pipe with an inlet and an outlet communicating with its inner cavity. The inlet is connected to a hopper. A spiral feeding rod corresponding to the outlet is installed inside the feeding pipe, and the spiral feeding rod is used to transfer material falling into the feeding pipe to the outlet. The hopper is equipped with a valve for closing the hopper channel. The mechanism body also includes a motor, the output shaft of which is driven by an active magnet. The spiral feeding rod is equipped with a driven magnet, and the active magnet and the driven magnet are magnetically coupled. The feeding pipe is sealed with a cover plate to isolate the active magnet and the driven magnet. When the motor drives the active magnet to rotate, the active magnet drives the driven magnet to rotate through magnetic coupling, which in turn drives the spiral feeding rod to rotate.

[0009] Furthermore, the cover plate is detachably and fixedly connected to the feeding pipe.

[0010] Furthermore, the outlet of the feeding pipe is hinged with a baffle plate, which is used to open and close the outlet.

[0011] Furthermore, the feeding pipe is provided with copper sleeves that correspond one-to-one with both ends of the spiral feeding rod, and the spiral feeding rod is rotatably mounted in the feeding pipe through the copper sleeves.

[0012] Furthermore, a connecting flange is fixedly installed in the middle of the outer peripheral wall of the feeding pipe.

[0013] Furthermore, a docking flange and a vibration damping hose are sequentially arranged above the hopper from top to bottom. The lower end of the vibration damping hose is sealed to the hopper, and the upper end of the vibration damping hose is sealed to the docking flange.

[0014] Furthermore, an electric vibrator is installed on the outer wall of the mating flange.

[0015] Furthermore, the valve is a pneumatic ball valve or a butterfly valve.

[0016] Furthermore, the spiral feed rod is located directly below the feed inlet.

[0017] Furthermore, the outer peripheral wall of the spiral feed rod is provided with spiral blades.

[0018] The beneficial effects of this utility model after adopting the above structure are as follows:

[0019] (1) The feeding mechanism of this utility model includes a mechanism body, the mechanism body including a feeding pipe, the feeding pipe being provided with an inlet and an outlet communicating with its inner cavity, the feeding pipe being provided with a spiral feeding rod corresponding to the outlet, the spiral feeding rod being used to transfer the material falling into the feeding pipe to the outlet; the mechanism body is also provided with a motor, the output shaft of the motor being drivenly connected to an active magnet, the spiral feeding rod being provided with a driven magnet, the active magnet and the driven magnet being magnetically coupled together. The cover plate of this utility model does not need to open the transmission shaft hole of traditional machinery, the connection between the motor and the feeding pipe adopts a fully enclosed structure, the active magnet and the driven magnet are isolated by the cover plate, which ensures both magnetic field penetration coupling and physical isolation. When the output shaft of the motor drives the active magnet to rotate, the active magnet drives the driven magnet to rotate through magnetic coupling, and then the driven magnet drives the spiral feed rod to rotate. This eliminates the problem of poor air tightness caused by the shaft hole in traditional mechanical seals, ensuring that the entire feeding process operates stably in an oxygen-free and clean environment, and meeting the stringent requirements for feeding powders with high sealing requirements (such as titanium alloy powder).

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0034] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 4As shown, a feeding mechanism includes a mechanism body 100, which includes a feeding pipe 1. The feeding pipe 1 is provided with an inlet 11 and an outlet 12 communicating with its inner cavity. The inlet 11 is connected to a hopper 2. A spiral feeding rod 3 corresponding to the outlet 12 is provided inside the feeding pipe 1. The spiral feeding rod 3 is used to transfer the material falling into the feeding pipe 1 to the outlet 12. The hopper 2 is provided with a valve 21 for closing the channel of the hopper 2. The main body 100 is also equipped with a motor 4, the output shaft 41 of which is driven by an active magnet 411. The spiral feed rod 3 is equipped with a driven magnet 31. The active magnet 411 and the driven magnet 31 are magnetically coupled together. The feeding pipe 1 is sealed with a cover plate 5 to isolate the active magnet 411 and the driven magnet 31. When the motor 4 drives the active magnet 411 to rotate, the active magnet 411 drives the driven magnet 31 to rotate through magnetic coupling, which in turn drives the spiral feed rod 3 to rotate. The cover plate 5 is detachably fixed to the feeding pipe 1. The valve 21 is a pneumatic ball valve or a butterfly valve. The spiral feed rod 3 is located directly below the feed inlet 11. The outer peripheral wall of the spiral feed rod 3 is provided with spiral blades 33.

[0036] Based on the above embodiments, the present invention aims to provide a feeding mechanism, including a mechanism body 100. The mechanism body 100 includes a feeding pipe 1, which is provided with an inlet 11 and an outlet 12 communicating with its inner cavity. A spiral feeding rod 3 corresponding to the outlet 12 is provided inside the feeding pipe 1, and the spiral feeding rod 3 is used to transfer the material falling into the feeding pipe 1 to the outlet 12. The mechanism body 100 is also provided with a motor 4, the output shaft 41 of the motor 4 is drivenly connected to an active magnet 411, and the spiral feeding rod 3 is provided with a driven magnet 31. The active magnet 411 and the driven magnet 31 are magnetically coupled together. The cover plate 5 of the present invention does not require the traditional mechanical drive shaft hole. The connection between the motor 4 and the feeding pipe 1 adopts a fully enclosed structure. The active magnet 411 and the driven magnet 31 are isolated by the cover plate 5, which ensures both magnetic field penetration coupling and physical isolation. When the output shaft 41 of the motor 4 drives the active magnet 411 to rotate, the active magnet 411 drives the driven magnet 31 to rotate through magnetic coupling, and then the driven magnet 31 drives the spiral feed rod 3 to rotate. This eliminates the problem of poor air tightness caused by the shaft hole in traditional mechanical seals, and ensures that the entire feeding process operates stably in an oxygen-free and clean environment, meeting the stringent requirements for feeding powders with high sealing requirements (such as titanium alloy powder).

[0037] In this embodiment, the feeding pipe 1 is sealed with a cover plate 5 for isolating the active magnet 411 and the driven magnet 31, and the cover plate 5 is detachably fixed to the feeding pipe 1. Figure 1 As shown, the cover plate 5 also serves as a rear end cover. The detachable design of the cover plate 5 facilitates the maintenance and upkeep of the internal components of the mechanism body 100. After removing the cover plate 5, it is convenient to perform repairs, replacements, and other operations on the internal components of the mechanism body 100. The cover plate 5 isolates the inner cavity of the feeding pipe 1 from the motor 4, and the cover plate 5 is made of a non-magnetic material, which ensures both magnetic field penetration and coupling, and physical isolation.

[0038] In another preferred embodiment of this utility model, a baffle plate 121 is hinged to the outlet 12 of the feeding pipe 1. The baffle plate 121 is used to open and close the outlet 12, and the baffle plate 121 is hinged to the upper wall of the outlet 12 via a hinge. In this embodiment, as... Figure 3 As shown, when the main equipment is feeding material, the mechanism body 100 is tilted forward. At this time, the material blocking plate 121 is open relative to the discharge port 12 under its own gravity; Figure 4 As shown, when the main equipment completes powder processing and pours out the finished powder, the main body 100 of the mechanism is tilted backward. At this time, the material blocking plate 121 is closed relative to the discharge port 12 under its own gravity to prevent the finished powder from entering the feeding pipe 1.

[0039] As another preferred embodiment of this utility model, the feeding pipe 1 is provided with copper sleeves 32 corresponding to both ends of the spiral feeding rod 3, and the spiral feeding rod 3 is rotatably mounted in the feeding pipe 1 through the copper sleeves 32. In this embodiment, as... Figure 1 As shown, the spiral feed rod 3 is rotatably connected to the feed pipe 1 via a copper sleeve 32. Using a copper sleeve 32 instead of a bearing prevents powder from entering the bearing and causing jamming.

[0040] As another preferred embodiment of this utility model, a connecting flange 6 is fixedly provided in the middle of the outer peripheral wall of the feeding pipe 1. In this embodiment, as... Figure 3 and Figure 4As shown, the feeding pipe 1 is fixedly connected to the main unit connector 200 via a connecting flange 6, and an O-ring seal 61 is provided at the connection to achieve a sealing fit between the connecting flange 6 and the main unit connector 200. This structural design has two advantages: first, it ensures the sealing between the feeding pipe 1 and the main unit connector 200; second, the feeding pipe 1 is always fixedly connected to the main unit connector 200, simplifying the feeding process and improving feeding efficiency. The feeding process of traditional feeding devices can be seen in a hydrogen crushing furnace feeding car disclosed in Chinese Utility Model Patent No. CN216736066U, which inserts the transfer pipe at the front end of the discharge pipe into the main unit connector during feeding, and then pulls the feeding car out of the main unit connector after feeding is completed, making the feeding process cumbersome and inefficient. However, the mechanism body 100 of this utility model is fixedly connected to the main unit connector 200, eliminating the need to frequently insert and pull the feeding pipe 1 into and out of the main unit connector 200. Figure 4 As shown, when the main equipment finishes processing and pours out the finished powder, the finished powder flows out through the gap between the mechanism body 100 and the main equipment connector 200, thus achieving material discharge. In this embodiment, the main equipment is a hydrogen crushing furnace as an example for detailed explanation. Accordingly, the main equipment connector 200 refers to the connector connecting the hydrogen crushing furnace and the mechanism body 100. The feeding mechanism is a material temporary storage device for the hydrogen crushing furnace. The material to be processed (such as titanium alloy powder) is transported to the feeding mechanism by an electric hoist, and then conveyed to the cylinder of the hydrogen crushing furnace for hydrogen crushing processing through the feeding mechanism.

[0041] In another preferred embodiment of this utility model, a docking flange 22 and a vibration-damping hose 23 are sequentially arranged from top to bottom above the hopper 2. The lower end of the vibration-damping hose 23 is sealed to the hopper 2, and the upper end of the vibration-damping hose 23 is sealed to the docking flange 22. In this embodiment, as... Figure 1 As shown, when the material to be processed (such as titanium alloy powder) is transported to the feeding mechanism by the electric hoist, the material is stored in the feeding hopper (not shown in the figure). The feeding hopper is moved by the electric hoist and is connected to the hopper 2 through the docking flange 22. The material to be processed in the feeding hopper is added to the hopper 2. When the electric hoist moves the feeding hopper above the hopper 2, the force is buffered by the shock-absorbing hose 23, which helps to improve the service life of the product.

[0042] As another preferred embodiment of this utility model, an electric vibrator 24 is provided on the outer wall of the mating flange 22. In this embodiment, as... Figure 1 As shown, the electric vibrator 24 vibrates intermittently, thereby achieving smooth material flow and low-pollution conveying.

[0043] As another preferred embodiment of this utility model, the valve 21 is a pneumatic ball valve or a butterfly valve. In this embodiment, as... Figure 1As shown, the hopper 2 is equipped with a valve 21, which is a pneumatic ball valve or a butterfly valve. The valve 21 can close the channel of the hopper 2, thereby improving the sealing performance of the hopper 2.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
