Description

Technical Field

[0001] This utility model relates to the field of powder feeding technology, specifically a powder feeding machine for bearing steel production. Background Technology

[0002] Bearing steel is used to manufacture balls, rollers, and bearing rings. In the production process of bearing steel, a powder feeder is used to feed steel powder for subsequent processing such as pressing.

[0003] The patent with publication number CN220950043U discloses a powder pusher for bearing steel production, including a pusher body. A feeding port is located at the top of the pusher body, and a mixing cylinder is located on the lower left side of the pusher body. A driving pusher mechanism is located between the two. The driving pusher mechanism includes a rotating shaft vertically installed in the mixing cylinder. A drive motor is located between the upper end of the rotating shaft and the inner surface of the upper end of the pusher body. A pushing component is horizontally arranged inside the pusher body, and a mixing component that fits against the inner wall of the mixing cylinder is sleeved on the lower end of the rotating shaft. This powder pusher, by combining the driving pusher mechanism, the pusher body, and the mixing cylinder, can both centrally push multiple materials falling into the pusher body and mix the centrally pushed materials, ensuring uniform mixing of multiple materials, increasing the uniformity of subsequent material output processing, improving material performance, and reducing performance deviations caused by strong individual material properties.

[0004] The above-mentioned device still has the following defects: During the use of the powder pusher, its discharge port needs to continuously feed the powder. When the powder falls from the discharge port to a certain extent, due to internal friction, cohesion, external friction with the silo wall, or factors such as moisture absorption or excessive storage time, the material forms a stable arched support structure in the silo, which becomes a resistance to the flow of material, hindering the subsequent material from falling, and ultimately causing the discharge to be interrupted or slow. This results in poor material feeding of the powder pusher, affecting the continuity and stability of the device's production, and adversely affecting production efficiency and product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a powder pusher for bearing steel production, which facilitates regular cleaning of the discharge port and improves production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder pusher for bearing steel production, comprising a powder pusher body and a support frame and a discharge pipe mounted on the powder pusher body. A base is fixedly connected to the front surface of the support frame, an electric push rod is fixedly connected to the upper surface of the base, a support plate is mounted on the top of the electric push rod, a servo motor is fixedly connected to the upper surface of the support plate at the location of the discharge pipe, the output end of the servo motor is connected to a rotating shaft via a coupling, a connecting shaft is mounted on the rotating shaft, and multiple evenly distributed cleaning plates are fixedly connected to the outer wall of the connecting shaft.

[0007] Furthermore, the cleaning contact surface between the cleaning plate and the inner wall of the discharge pipe is set with an arc-shaped tangent.

[0008] Furthermore, a second rotating groove is provided at the top of the electric actuator, and a first rotating groove connected to the second rotating groove is provided at the lower end of the electric actuator. A threaded insertion port extending through the second rotating groove is provided on the outer wall of the electric actuator. A turntable is rotatably connected in the first rotating groove, and a rotating column is rotatably connected in the second rotating groove. The upper end of the rotating column is fixedly connected to the lower surface of the support plate. Two mutually perpendicular and interconnected threaded positioning grooves are provided on the outer wall of the rotating column. A T-shaped fastening bolt is threadedly connected in the threaded insertion port. The T-shaped fastening bolt is a combination of a bolt and a rectangular block, and the rectangular block is located outside the electric actuator.

[0009] Furthermore, a fixing member is fixedly connected to the upper end of the rotating shaft, and a receiving frame is installed on the upper end of the fixing member. The inner bottom surface of the receiving frame is fixedly connected to the lower end of the connecting shaft, and the inner bottom surface of the receiving frame maintains a distance from the multiple cleaning plates.

[0010] Furthermore, the fixing components are a mounting plate and fastening bolts. The upper end of the rotating shaft is fixedly connected to the lower end of the mounting plate. The upper end of the mounting plate is in close contact with the lower surface of the receiving frame. The fastening bolts pass through the mounting plate into the receiving frame for bolt tightening.

[0011] Furthermore, an ultrasonic sensor is fixedly attached to the front surface of the support frame, the transmitter of the ultrasonic sensor is arranged parallel to the outlet of the discharge pipe, a controller is fixedly attached to the upper surface of the base, a warning light plate is fixedly attached to the surface of the controller away from the powder pusher body, and a buzzer is fixedly attached to the surface of the warning light plate away from the controller.

[0012] Furthermore, the controller is electrically connected to the main power supply of the powder pusher body, the ultrasonic sensor, the electric push rod, and the servo motor via wires. The main power supply of the powder pusher body is electrically connected to the ultrasonic sensor, the electric push rod, the servo motor, the warning light board, and the buzzer via wires. The ultrasonic sensor is electrically connected to the warning light board and the buzzer via wires.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model utilizes the cooperation of an electric push rod, a servo motor, a rotating shaft, a connecting shaft, and a cleaning plate. First, the extension and retraction of the electric push rod 7 is controlled to drive the support plate 8 and the cleaning plate 15 mounted on it to move upward and insert into the discharge pipe 3. Then, the servo motor 9 is started, and with the help of the transmission mechanism of the rotating shaft and the connecting shaft, the cleaning plate 15 is driven to perform a rotating scraping cleaning operation in the discharge pipe 3. This design can specifically break and remove the blockage caused by the "arching" of powder in the discharge pipe, keeping the discharge pipe 3 clean and unobstructed, thereby avoiding the problem of obstructed feeding speed and improving the overall production efficiency and operational stability of the device. The structure is simple, easy to operate, and highly practical.

[0015] 2. This utility model, through the cooperation of the rotating column, turntable, T-shaped fastening bolts, and receiving frame, allows the operator to flexibly rotate the support plate 8 when no cleaning is required. The coordinated rotation of the rotating column and turntable smoothly rotates the support plate 8 and all its components to one side of the device. Then, the T-shaped fastening bolts are tightened to fix the support plate 8 in place. Simultaneously, any powder dropped during cleaning is collected in the receiving frame, facilitating subsequent centralized collection and recycling. This not only reduces material waste but also lowers production costs, aligning with green and environmentally friendly production principles. Furthermore, it integrates intelligent monitoring and alerting devices such as ultrasonic sensors, warning lights, and buzzers. The ultrasonic sensors can monitor the material status within the discharge pipe in real time and accurately. Once an abnormality is detected, such as powder "arching" or blockage, the warning lights will flash and the buzzer will sound an alarm, promptly reminding the operator to take appropriate measures. This prevents production failures caused by discharge pipe problems and further enhances the device's intelligence and production safety. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 6 As shown, a powder pusher for producing bearing steel includes a powder pusher body 1 and a support frame 2 and a discharge pipe 3 mounted on the powder pusher body 1. A base 5 is fixed to the front surface of the support frame 2, and an electric push rod 7 is fixed to the upper surface of the base 5. A support plate 8 is installed at the top of the electric push rod 7. A servo motor 9 is fixed to the upper surface of the support plate 8 at the location of the discharge pipe 3. The output end of the servo motor 9 is connected to a rotating shaft 10 through a coupling. A connecting shaft 14 is installed on the rotating shaft 10, and multiple evenly distributed cleaning plates 15 are fixed to the outer wall of the connecting shaft 14.

[0025] like Figure 1 As shown, the powder pusher for bearing steel production in this utility model is structurally similar to existing powder pushers for bearing steel production. For example, patent publication number CN220950043U discloses a powder pusher for bearing steel production. The main improvement of this utility model is that it facilitates regular cleaning of the discharge port, thereby improving production efficiency. Figures 1 to 6As shown, in the powder pusher for bearing steel production of this utility model, the main body 1 of the powder pusher may experience "arching" in the discharge pipe 3 due to various adverse factors (especially the rainy season) during long-term use, causing blockage or inconvenience in discharge, which affects the overall production and material feeding. To address this, the electric push rod 7 is first controlled to drive the support plate 8 upward, allowing the cleaning plate 15 on the support plate 8 to be inserted into the opening of the discharge pipe 3. Subsequently, the servo motor 9 is started, driving the rotating shaft 10 to open and rotating the connecting shaft 14 together. This causes the multiple cleaning plates 15 in the rotation process to continuously scrape the inner wall of the discharge pipe 3, rotating and scraping off the residual material or the "arched" parts attached to the inner wall of the discharge pipe 3, so that the discharge pipe 3 can remain clean and unblocked, without affecting the material feeding speed, and improving the overall production efficiency of the device.

[0026] It should be noted that all cleaning plates 15 need to be smooth and have corrosion-resistant and wear-resistant layers. This can improve the overall working effect of the cleaning plates 15 and also better protect the discharge pipe 3.

[0027] In addition, after starting, the servo motor 9 can rotate forward for a period of time and then rotate in reverse for a period of time to enhance the cleaning effect of the device.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the cleaning contact surface between the cleaning plate 15 and the inner wall of the discharge pipe 3 is set with an arc-shaped tang. By setting the arc-shaped tang, on the one hand, friction can be reduced, wear can be reduced and the structure can be protected. On the other hand, the arc transition surface can fit the shape of the inner wall of the discharge pipe 3, making the contact tighter, enhancing the cleaning force, and reducing jamming. The tang also enhances the scraping effect and improves the cleaning ability.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the top of the electric actuator 7 is provided with a second rotating groove 17, and the lower end of the electric actuator 7 is provided with a first rotating groove 16 that communicates with the second rotating groove 17. The outer wall of the electric actuator 7 is provided with a threaded socket 18 that extends into the second rotating groove 17. A turntable 20 is rotatably connected in the first rotating groove 16, and a rotating column 19 is rotatably connected in the second rotating groove 17. The upper end of the rotating column 19 is fixed to the lower surface of the support plate 8. The outer wall of the rotating column 19 is provided with two mutually perpendicular and interconnected threaded positioning grooves 21. A T-shaped fastening bolt 22 is threadedly connected in the threaded socket 18. The T-shaped fastening bolt 22 is a combination of a bolt and a rectangular block, and the rectangular block is located outside the electric actuator 7.

[0030] Specifically, when the device is not in use, it needs to be removed, otherwise it will affect the feeding operation of the powder pusher body 1. First, unscrew the T-shaped fastening bolt 22. Then, rotate the support plate 8 and all its components by 90° to change its direction. Next, screw the T-shaped fastening bolt 22 into the threaded socket 18 and the corresponding threaded positioning groove 21 and tighten it to fix the device. This will not hinder the normal operation of the device.

[0031] It is worth noting that the threaded socket 18 can be located within a 90° range close to the controller 6. At this time, if the T-shaped fastening bolt 22 is tightened, the current state of the support plate 8 is that the cleaning plate 15 is located below the outlet of the discharge pipe 3. The support plate 8 can then be pushed upward by the electric push rod 7 to insert the cleaning plate 15 into the discharge pipe 3.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, a fixing member is fixedly connected to the upper end of the rotating shaft 10, and a receiving frame 12 is installed on the upper end of the fixing member. The inner bottom surface of the receiving frame 12 is fixedly connected to the lower end of the connecting shaft 14, and the inner bottom surface of the receiving frame 12 maintains a distance from the multiple cleaning plates 15.

[0033] Specifically, by fixing the connecting shaft 14 and the cleaning plate 15 together inside the receiving frame 12, when the device controls the cleaning plate 15 to clean, the powder that falls off will be stored in the receiving frame 12, which can be recycled and reused, and the degree of powder scattering can also be reduced. Most of the powder will be stored in the receiving frame 12.

[0034] It is worth noting that, since the cleaning plate 15 is set to maintain a distance from the inner bottom surface of the receiving frame 12, during the cleaning process, you can choose to first insert the entire connecting shaft 14 and the cleaning plate 15 into the discharge pipe 3, so that the opening of the discharge pipe 3 is in contact with the inner bottom surface of the receiving frame 12, and then perform selective scraping. In this way, the powder generated during the scraping process will first be in the discharge pipe 3. Then, you can stop the cleaning device for a while and let the powder that has been disturbed by the cleaning plate 15 stand still for a while. Then, control the electric push rod 7 to move down as a whole, so that the powder slowly falls into the receiving frame 12, reducing the degree of powder flying and enhancing the cleaning effect.

[0035] like Figure 1 and Figure 2 As shown, the fasteners are mounting plate 11 and fastening bolt 13. The upper end of the rotating shaft 10 is fixedly connected to the lower end of the mounting plate 11. The upper end of the mounting plate 11 is in close contact with the lower surface of the receiving frame 12. The fastening bolt 13 passes through the mounting plate 11 into the receiving frame 12 for bolt fastening.

[0036] Specifically, the receiving frame 12 is fixed to the mounting plate 11 by fastening bolts 13, so that the receiving frame 12 and the rotating shaft 10 form a detachable connection, which facilitates the removal and pouring out of the received powder, as well as the cleaning or replacement of the receiving frame 12, the connecting shaft 14 and the cleaning plate 15.

[0037] like Figure 1 and Figure 2 As shown, an ultrasonic sensor 4 is fixedly attached to the front surface of the support frame 2. The transmitter of the ultrasonic sensor 4 is arranged parallel to the opening of the discharge pipe 3. A controller 6 is fixedly attached to the upper surface of the base 5. A warning light plate 23 is fixedly attached to the surface of the controller 6 away from the powder pusher body 1. A buzzer 24 is fixedly attached to the surface of the warning light plate 23 away from the controller 6.

[0038] Specifically, the ultrasonic sensor 4 is used to monitor the powder blockage in the discharge pipe 3. The ultrasonic sensor 4 emits an ultrasonic beam (usually a high-frequency sound wave) into the discharge pipe 3. When the sound wave encounters the powder surface, it is reflected back to the ultrasonic sensor 4. The ultrasonic sensor 4 calculates the time difference between the ultrasonic emission and reception. Combined with the speed of sound in the air (about 340m / s), the distance from the sensor to the powder surface can be measured. During normal discharge, the powder flows smoothly, and the distance detected by the ultrasonic sensor 4 will remain within the set range. If a blockage occurs, the powder will accumulate in the discharge pipe 3, causing the distance detected by the ultrasonic sensor 4 to continuously decrease (i.e., the material height increases). When it exceeds the normal range, it can be determined as a blockage. Based on the change in range, in conjunction with the warning light panel 23, the signal will be converted into light display in sequence, which can be "green light normal", "yellow light warning (blockage occurs but is not serious and does not affect normal operation)" and "red light blockage (serious blockage, seriously affects the operation of the device, and needs to be cleaned)". When the display shows red light blockage, the buzzer 24 will sound an alarm at the same time to remind the staff that the device needs to be cleaned.

[0039] It is worth noting that the aforementioned setting range needs to be adjusted by the user according to the actual production scenario, and the data needs to be corrected regularly to reduce deviation. In addition, the ultrasonic sensor 4 on this device can be a short ultrasonic sensor with analog output function (such as some industrial-grade products). It needs to support dual output of switch quantity and analog quantity to meet the needs of powder detection. At the same time, it should also have a certain anti-interference capability and environmental adaptability (such as dustproof sealing). When choosing a manufacturer, they can give priority to short-range ultrasonic models of industrial sensor brands such as Siemens, Pepperl+Fuchs, and Turck (such as Siemens' UC series and Pepperl+Fuchs' UM series). These brands' products usually support customized parameters (such as detection frequency and range) and can be configured according to the specific pusher size and powder characteristics (such as particle size and flowability).

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, the controller 6 is electrically connected to the main power supply of the powder pusher body 1, the ultrasonic sensor 4, the electric push rod 7, and the servo motor 9 via wires. The main power supply of the powder pusher body 1 is electrically connected to the ultrasonic sensor 4, the electric push rod 7, the servo motor 9, the warning light panel 23, and the buzzer 24 via wires. The ultrasonic sensor 4 is electrically connected to the warning light panel 23 and the buzzer 24 via wires.

[0041] Specifically, by connecting these electrical components that require power and control via wires, the controller 6 can control the total power supply of the powder pusher body 1 to power all the components that require power, as well as power the controller 6 itself. At the same time, it controls the ultrasonic sensor 4 to turn on and off, the electric push rod 7 to turn on and off and move up and down, and the servo motor 9 to turn on and off and rotate forward and backward. Finally, when the ultrasonic sensor 4 has completed its monitoring, it will send a signal to the controller 6 first. Then, the controller 6 will control the warning light panel 23 and the buzzer 24 to make corresponding changes.

[0042] Finally, it is important to emphasize that all electronic control components in this device (such as ultrasonic sensor 4, controller 6, electric actuator 7, servo motor 9, warning light panel 23, and buzzer 24) must be dustproof. Controller 6 can be a PLC controller. The overall control logic is as follows: ultrasonic sensor 4 detects blockage in the discharge pipe 3 and sends the result to controller 6. Based on the detection result, it controls the warning light panel 23 and buzzer 24 to make corresponding state changes. Buzzer 24 will alarm when emitting red or yellow light, but with different displays (e.g., one louder and one softer, or one longer and one shorter; the manufacturer can choose according to the actual situation). Subsequently, the staff controls controller 6 to perform a series of cleaning processes.

[0043] 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.
