Description

Technical Field

[0001] The present invention relates to the field of scraping equipment, and more specifically, to an automatic powder scraping mechanism and a method for using the same. Background Art

[0002] Powder sintering filter element is an important manufacturing process in the field of powder metallurgy. It is widely used in many industries such as automobile, aerospace, chemical and medical because it can produce filter element products with complex structure and high performance. One of the core steps of powder sintering filter element is to accurately fill metal or non-metal powder into a mold with a preset shape, and then form a strong metallurgical bond between powder particles through subsequent processes such as pressing and sintering, and finally obtain a finished filter element with the required strength and filtration performance.

[0003] In the existing powder filling process, a significant technical difficulty is that it is difficult to ensure the surface flatness of the powder after it is filled into the mold. Due to the special physical properties of the powder, such as particle size distribution, fluidity, etc., as well as factors such as vibration and friction that may exist during the filling process, the upper surface of the powder in the mold often presents an uneven and bumpy state. This uneven and bumpy state not only affects the uniformity of the subsequent pressing process and the density distribution of the finished filter element, but may also cause uneven heat conduction during the sintering process, thereby affecting the overall performance and quality consistency of the filter element.

[0004] In order to solve the above problems, the traditional approach relies on manual scraping, that is, the operator uses a scraper or similar tool to manually adjust the surface of the powder in the mold to achieve a relatively flat state. Although this method can improve the flatness of the powder surface to a certain extent, its inherent limitations cannot be ignored: first, it is inefficient, manual operation takes a long time, and it is difficult to adapt to the modern industrial production requirements for high efficiency and speed; second, there are metering errors. It is difficult to accurately control the amount of scraped powder during manual scraping, which may cause the key parameters of the filter element, such as weight and thickness, to deviate from the design standards; third, manual operation is highly subjective, and the differences in skill levels and judgment standards of different operators may lead to unstable product quality.

[0005] More importantly, the manual scraping process is difficult to automate and intelligentize, which has become a key factor hindering the full integration of filter element preparation technology into the automated production line. With the accelerated advancement of the manufacturing industry's transformation toward intelligence and digitalization, how to achieve automatic scraping after powder filling has become a technical problem that needs to be solved urgently to improve filter element production efficiency, ensure product quality stability, and reduce labor costs.

[0006] There are existing scraping devices in other fields, such as the invention patent with publication number CN111238903A, which discloses a scraping device, which relates to the technical field of preparation of test samples. The scraping device includes a scraping component, a first drive module, a waste collection component and a second drive module; the scraping component includes a scraping ruler, which is transmission-connected to the first drive module, and the scraping ruler can drop the material on the upper surface of the test mold under the drive of the first drive module; the waste collection component includes a receiving member, which is transmission-connected to the second drive module; the receiving member is provided with an avoidance hole for being sleeved on the outer peripheral surface of the test mold, for receiving the material dropped from the test mold, which is suitable for cement mortar molding samples, but not suitable for scraping powder, especially when the powder is mixed with larger particles, the scraping ruler disclosed above is even more inapplicable.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0022] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0023] like Figures 1 to 6 As shown, the present invention provides a powder automatic scraping mechanism, comprising: The scraping assembly comprises: Motor; a pair of flanges connected to the free ends of the motor and rotating with the motor shaft; A plurality of blades 7 are arranged in an array along the circumference of the motor shaft between a pair of flanges and rotate along the circumference of the motor shaft with the flanges, and any blade 7 at least abuts against the scraping plane when rotating with the flanges; A driving assembly connected to the scraping assembly and driving the scraping assembly to reciprocate along the extension direction of the scraping surface; Wherein, any blade 7 is rotatably connected to a pair of flanges.

[0024] In the above technical scheme, the automatic powder scraping mechanism includes a scraping component and a driving component, the driving component is used to drive the scraping component to reciprocate along the extension direction of the scraping plane (scraping path), the driving component includes a servo electric cylinder 13, the servo electric cylinder 13 drives the guide rail 1 to move linearly, and the guide rail 1 drives the scraping component to automatically reciprocate along the extension direction of the scraping plane; the scraping component includes a motor, the motor drives a pair of flanges to rotate circumferentially, thereby driving the blades 7 distributed in the circumferential array to automatically rotate circumferentially to complete the revolution of the blades 7, any blade 7 is in contact with the scraping plane at least in the vertical direction during the rotation process, thereby realizing the scraping of the powder, and the automatic scraping of the powder is realized by automated means, which reduces the time and cost of manual operation and improves the efficiency of powder scraping. The automated scraping mechanism can accurately control the scraping speed and force to ensure the flatness and uniformity of the powder surface, thereby improving the quality of subsequent finished products, and the automatic powder scraping mechanism can be easily integrated into the automated production line to achieve docking with upstream and downstream processes.

[0025] In the above technical solution, the scraping assembly includes a motor, a pair of flanges, and a plurality of blades 7. The pair of flanges are connected to the free end of the motor through a connecting piece (coupling 8 and rotating shaft 14), and rotate circumferentially with the motor shaft. The plurality of blades 7 are distributed in an array along the circumference of the motor shaft between the pair of flanges. The flange is provided with a structure for mounting the blades 7, and any blade 7 is rotatably connected to the flange. The blades 7 rotate slightly during the scraping process to complete the adaptive rotation of the blades 7. The shape and number of the blades 7 can be radially customized according to the size and shape of the scraping surface. Preferably, the number of blades 7 arranged in the circumferential array is 8 to 16; any blade 7 at least has a state of abutting the scraping surface during the rotation process to scrape the powder surface. The blades 7 are rotatably connected to the flanges, which greatly improves the adaptability of the automatic powder scraping mechanism. Figure 5 As shown, when the surface of the metal powder is relatively flat, the rotation angle of the blade 7 (the angle between the blade 7 and the rotating shaft 14) is relatively large, and the rotation speed of the blade 7 can be increased. Figure 6 As shown, when the surface of the metal powder is relatively uneven (the metal powder particles are large or mixed with large particles), the blade 7 automatically adjusts its angle, and the rotation angle of the blade 7 (the angle between the blade 7 and the rotating shaft 14) becomes smaller, ensuring that larger metal particles are scraped away and the free end of the blade 7 is not easily damaged.

[0026] like Figure 3 and Figure 4 As shown, in one of the technical solutions, a self-lubricating copper sleeve is provided on any flange and passes through the flange, and the self-lubricating copper sleeve corresponds to the blade 7 one by one; short shafts 17 cooperating with the self-lubricating copper sleeve are provided at the two ends of any blade 7 away from the scraping plane.

[0027] In the above technical solution, a plurality of self-lubricating copper sleeves are provided on any flange, and these self-lubricating copper sleeves run through the entire flange, that is, they pass from one side of the flange to the other side. The positions of the self-lubricating copper sleeves on a pair of flanges correspond, and the number of the self-lubricating copper sleeves on the flange corresponds one by one to the number of blades 7, ensuring that each blade 7 rotates smoothly and with low friction through its corresponding copper sleeve. The self-rotation of the blade 7 relative to the self-lubricating copper sleeve is frequent during the scraping operation. The self-lubricating copper sleeve is beneficial to reducing the friction and wear of the short shaft 17, and the self-lubricating copper sleeve can self-lubricate, reducing the dependence on external lubricants, and also improving the reliability and service life of the scraping assembly.

[0028] In the above technical solution, a notch is provided on one side where the short shaft 17 is connected to the blade 7, and the blade 7 is embedded in the notch, and the short shaft 17 is provided at the two upper ends of the blade 7. The short shafts on both sides and the blades are welded as one piece. A notch is cut through the short shaft to position the welding of the blade, and there is space for filling flux; the notches are set on the short shafts on both sides to ensure the coaxiality of the short shafts on both sides when welding with the blades. A retaining ring for mounting the shaft is provided on any short shaft, and the flange close to the motor body 9 is defined as the inner flange, and the flange away from the motor body 9 is defined as the outer flange. During installation, the blade 7 is first connected to the inner flange, and then the outer flange is installed, and finally the outer flange is fixed with the outer locking nut.

[0029] like Figure 1 and Figure 2 In one of the technical solutions, the driving assembly includes: A servo electric cylinder 13, which is arranged along the extension direction of the scraping plane; A guide rail 1, which is arranged in parallel with the servo motor and is connected to the end of the piston rod 15 of the servo electric cylinder 13 through an L-shaped connecting plate 16 and reciprocates with the piston rod 15; Among them, one end of the guide rail 1 close to the piston rod 15 is connected to the scraping assembly and drives the scraping assembly to reciprocate along the extension direction of the scraping surface.

[0030] In the above technical solution, the driving component adopts the servo electric cylinder 13 as the power source to drive the scraping component to reciprocate, thereby realizing the precise control of the movement of the scraping component. The servo electric cylinder 13, together with the high-precision displacement control and stable output force, ensures that the scraping component can reciprocate in the extension direction of the scraping surface according to the predetermined trajectory and speed, thereby improving the precision and efficiency of the scraping operation. The guide rail 1 is arranged in parallel with the servo electric cylinder 13, and is connected to the end of the piston rod 15 of the servo electric cylinder 13 through the L-shaped connecting plate 16. This structural design not only enhances the stability and rigidity of the driving component, but also enables the guide rail 1 to move smoothly with the reciprocating motion of the piston rod 15. The linear motion characteristics of the guide rail 1 further ensure the linearity of the motion trajectory of the scraping component, avoiding the problem of poor scraping effect caused by motion deviation. Furthermore, the end of the guide rail 1 close to the piston rod 15 is connected to the scraping component, directly driving the scraping component to reciprocate along the extension direction of the scraping surface. This driving method reduces the intermediate transmission link and improves the response speed and transmission efficiency of the system.

[0031] In one of the technical solutions, a pair of flanges are sleeved on a rotating shaft 14, the rotating shaft 14 is connected to the motor shaft of the motor through a coupling 8, the coupling 8 is connected to the guide rail 1 through a pair of mounting plates 5, the pair of mounting plates 5 are respectively arranged on the motor bearing seat and the motor bracket, and the guide rail 1 is arranged between the pair of mounting plates 5. The guide rail 1 is connected to the scraping assembly through a pair of mounting plates 5, and the guide rail 1 is arranged between the pair of mounting plates 5, such as Figure 3 As shown, a pair of mounting plates 5 are preferably L-shaped. This connection method ensures the reliability of the connection between the guide rail 1 and the scraping assembly, and further ensures the stability and continuity of the scraping operation. At the same time, it optimizes space utilization, making the powder automatic scraping mechanism structure more compact and reasonable.

[0032] In the above technical solution, the flange is connected to the free end of the motor through the rotating shaft 14 and the coupling 8, the flange is sleeved on the rotating shaft 14, and the rotating shaft 14 is connected to the motor shaft of the motor through the coupling 8, so that the flange and the blades 7 connected thereto rotate smoothly with the rotation of the rotating shaft 14, and the motor shaft of the motor is connected to the rotating shaft 14 through the coupling 8, ensuring that the power output by the motor can be accurately and efficiently transmitted to the rotating shaft 14, thereby driving the flange and the blades 7 arranged thereon to rotate. A pair of mounting plates 5 are respectively arranged on the motor bearing seat and the motor bracket. The stable installation of the motor bearing seat and the motor bracket, the precise centering of the coupling 8, and the precise adjustment of the guide rail 1 all ensure that the entire mechanical structure has a high degree of stability and reliability during operation.

[0033] In one of the technical solutions, the automatic powder scraping mechanism further includes a bracket assembly for fixing the driving assembly, and the bracket assembly includes: A horizontal bracket 10 is arranged parallel to the guide rail 1, and a slider 4 cooperating with the guide rail 1 is arranged on the side of the horizontal bracket 10; A first L-shaped frame 12 is arranged on one side of the horizontal bracket 10 close to the servo electric cylinder 13, and a horizontal portion 122 of the first L-shaped frame is connected to at least the fixing flange 11 of the servo electric cylinder 13; a horizontal portion 22 of the second L-shaped frame is located on the same horizontal plane as the horizontal portion 122 of the first L-shaped frame; The second L-shaped frame 2 is disposed on the other side of the horizontal support 10 , and the vertical portion 21 of the second L-shaped frame is disposed at the same height as the vertical portion 121 of the first L-shaped frame, so as to be hung on a fixed object.

[0034] In the above technical solution, the bracket assembly serves as the core supporting structure, which includes a horizontal bracket 10, a first L-shaped frame 12 and a second L-shaped frame 2, which not only reduces the weight of the automatic powder scraping mechanism, but also ensures that the automatic powder scraping mechanism is fixed on a fixed object, such as a fixed platform, a beam, etc., so that the automatic powder scraping mechanism abuts on the scraping surface. The horizontal bracket 10 is arranged in parallel with the guide rail 1, and the slider 4 is closely matched with the slide rail, which eliminates the problem of poor scraping effect caused by shaking or deviation. At the same time, the stable connection between the first L-shaped frame 12 and the second L-shaped frame 2 provides reliable support for the servo electric cylinder 13 and the entire scraping device, and even in the long-term and high-frequency operation process, it can maintain the stability and durability of the structure, thereby extending the service life of the equipment.

[0035] In the above technical solution, the horizontal part of the first L-shaped frame 12 is connected to the fixed flange 11 of the servo electric cylinder 13, and no complicated installation process is required, which reduces the difficulty of installation. The vertical part of the second L-shaped frame 2 is set at the same height as the vertical part of the first L-shaped frame 12, which not only maintains the balance of the entire bracket assembly, but also facilitates the suspension of the mechanism on a fixed object, such as a beam or bracket or production platform on a production line, etc., to achieve flexible and diverse installation methods and meet the use requirements in different scenarios. The first L-shaped frame 12 and the second L-shaped frame 2 are firmly connected to the horizontal bracket 10, providing reliable support for the servo electric cylinder 13 and the entire automatic powder scraping mechanism, and maintaining the stability and durability of the structure even during long-term and high-frequency operation, thereby extending the service life of the equipment. The compact design of the bracket assembly effectively controls the occupied space of the entire automatic powder scraping mechanism, which not only meets the functional requirements but also reduces space waste. At the same time, the smooth lines and simple structure of the L-shaped frame enhance the overall aesthetics and ornamental properties, making the layout of the equipment on the production line more reasonable and neat.

[0036] like Figure 1 and Figure 2 As shown, in one of the technical solutions, the automatic powder scraping mechanism also includes a monitoring component, which includes: The 3D vision detector is connected to the horizontal support 10 via a mounting base 3 , and the 3D vision detector is located on the same straight line as the blade 7 along the extension direction of the guide rail 1 .

[0037] In the above technical solution, the monitoring component monitors the scraping effect in real time through a 3D visual detector. The 3D visual detector is firmly connected to the horizontal bracket 10 through a specially designed mounting seat 3, and the 3D visual detector is located on the same straight line as the blade 7 along the extension direction of the scraping plane. Compared with the traditional monitoring method, the use of the 3D visual detector greatly reduces human errors. The 3D visual detector is integrated with the horizontal bracket 10, so that the monitoring process can be completed without human intervention, which greatly improves the monitoring efficiency of the scraping effect, realizes continuous and online monitoring of the scraping effect, and improves the automation level and generation efficiency of the production line.

[0038] In one of the technical solutions, a pair of mounting plates 5 are provided with protective plates at the ends away from the slider 4 to prevent powder splashing and damaging the automatic powder scraping mechanism.

[0039] In one of the technical solutions, a protective cover 6 is provided on the blade 7, one end of the protective cover 6 is connected to the mounting plate 5, and the other end is rotatably connected to the rotating shaft 14 to block flying dust caused by scraping.

[0040] The present invention further claims a method for using the automatic powder scraping mechanism, comprising: Step 1: Set the process time required for leveling, and calculate the output speed of the servo electric cylinder according to the extension length of the scraping surface; Step 2: Adjust the motor speed according to the size of the powder particles on the scraped surface. The motor speed adjustment standard is: at the motor speed after adjustment, the powder surface is flat after being scraped; Step 3: Perform the scraping operation based on the output speed of the servo electric cylinder calculated in step 1 and the speed of the motor after debugging in step 2.

[0041] In the above technical scheme, the process time required for leveling in step one is set according to the rhythm of the production line, the output speed of the servo electric cylinder is equal to the ratio of the extension length of the scraping surface to the process time required for leveling, and the actual operation of leveling the powder surface after scraping in step two is: using the image of the 3D visual detector to check the flatness after scraping.

[0042] The number of equipment and processing scale described here are used to simplify the description of the present invention. The application, modification and variation of the automatic powder leveling mechanism of the present invention will be obvious to those skilled in the art.
