Description

Technical Field

[0001] This utility model relates to the field of iron powder processing technology, and more specifically, to a feeding mechanism for iron powder processing equipment. Background Technology

[0002] Iron powder is an aggregate of iron particles with a size less than 1 mm. It is a major raw material for powder metallurgy. Based on particle size, it is conventionally classified into five grades: coarse powder, medium powder, fine powder, microfine powder, and ultrafine powder. Iron powder has wide applications in both food and industry.

[0003] The existing feeding mechanism cannot screen the iron powder, resulting in iron powder that does not meet the particle size requirements being added into the processing equipment, affecting the processing quality of the iron powder.

[0004] A search revealed that Chinese patent CN214975495U discloses a feeding mechanism for iron powder processing equipment. This mechanism uses a filter screen to filter the iron powder, allowing qualified iron powder to be transported into the processing equipment for processing, thereby improving the processing quality of the iron powder. At the same time, unqualified iron powder is discharged for further crushing or other uses. The feeding device can be blocked or stopped as needed, allowing the feeding mechanism to feed normally even when the powder is not filtered.

[0005] In actual use, the feeding mechanism of the aforementioned iron powder processing equipment is prone to blockage by iron powder in the feed hopper, causing the feeding mechanism to malfunction and requiring frequent shutdowns for manual cleaning. This reduces production efficiency and affects the stability and efficiency of subsequent processing steps. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a feeding mechanism for iron powder processing equipment to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding mechanism for an iron powder processing equipment includes a screening box, wherein an anti-clogging component is installed on the upper surface of the screening box.

[0009] The anti-clogging component includes a fixed box, which is fixedly connected to the upper surface of the screening box. A feeding cylinder is installed on one side of the fixed box, and a feeding hopper is welded to the upper surface of the feeding cylinder. A first motor is installed on the upper surface of the fixed box, and a first gear is fixedly connected to the output end of the first motor. A second gear meshes with one side of the first gear, and the second gear is rotatably connected to the inside of the fixed box. A gear plate meshes with one side of the second gear, and the gear plate is rotatably connected to the inside of the feeding cylinder. Two scraping rods are fixedly connected to the inner side of the gear plate, and a first spiral blade is welded to the inner side of the gear plate.

[0010] By adopting the above technical solution, the iron powder inside the hopper can be stirred and scraped by the rotation of the first spiral blade and scraper rod, thereby preventing the iron powder from causing blockage inside the hopper and ensuring that the iron powder is conveyed downward at a stable speed and flow rate.

[0011] As a further description of the above technical solution: a screening mechanism is installed inside the screening box, the screening mechanism includes a vibration box, the vibration box is installed inside the screening box, a vibration motor is installed on one side of the vibration box, the vibration motor passes through the screening box, a first screening plate and a second screening plate are fixedly connected to the inside of the vibration box, the first screening plate is positioned above the second screening plate, a plurality of springs are fixedly connected to the bottom end of the vibration box, a support plate is fixedly connected to the bottom end of the springs, and the support plate is welded and fixed to the inside of the screening box.

[0012] By adopting the above technical solution, iron powder of different fineness can be effectively sorted under the action of the vibrating box, so that the conveyed iron powder can maintain a certain uniform size and improve the processing quality.

[0013] As a further description of the above technical solution: a first feeding port is connected to one side of the vibrating box, and a second feeding port is connected to the other side of the vibrating box. Both the first and second feeding ports are fixedly connected to the vibrating box. A second motor is installed on one side of the screening box, and a rotating shaft is fixedly connected to the output end of the second motor. A second spiral blade is welded to the outside of the rotating shaft. A third feeding port is connected to one side of the screening box.

[0014] By adopting the above technical solution, different iron powders can be discharged from the first feed port, the second feed port and the third feed port respectively, which makes it convenient to classify and transport iron powders of different fineness according to actual needs.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By setting up anti-clogging components, compared with existing technologies, the scraper rod and the first spiral blade driven by the toothed disc to rotate inside the feed cylinder can effectively prevent iron powder from accumulating inside the feed hopper, thereby avoiding clogging, reducing downtime caused by clogging, and thus improving production efficiency.

[0017] 2. By setting up a screening mechanism, compared with the existing technology, the vibration of the vibrating box inside the screening box enables the first screening plate and the second screening plate to screen iron powder of different finenesses, thereby maintaining the uniformity and consistency of iron powder before entering the processing equipment, which helps to improve processing efficiency and product quality.

[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 application discloses a feeding mechanism for an iron powder processing equipment, including a screening box 1, with an anti-clogging component installed on the upper surface of the screening box 1;

[0027] The anti-clogging component includes a fixed box 2, which is fixedly connected to the upper surface of the screening box 1. A feeding cylinder 3 is installed on one side of the fixed box 2, and a feeding hopper 10 is welded to the upper surface of the feeding cylinder 3. A first motor 4 is installed on the upper surface of the fixed box 2, and a first gear 5 is fixedly connected to the output end of the first motor 4. A second gear 6 meshes with one side of the first gear 5 and is rotatably connected to the inside of the fixed box 2. A gear disc 7 meshes with one side of the second gear 6 and is rotatably connected to the inside of the feeding cylinder 3. Two scraping rods 8 are fixedly connected to the inner side of the gear disc 7, and a first spiral blade 9 is welded to the inner side of the gear disc 7. By starting the first motor 4, the first motor... Machine 4 drives the first gear 5 to rotate, which in turn meshes with the second gear 6 to rotate. The rotation of the second gear 6 meshes with the gear disc 7 to rotate inside the feed cylinder 3. This allows the gear disc 7 to drive the scraper rod 8 and the first spiral blade 9 to rotate. The spiral action of the first spiral blade 9 accelerates the falling speed of the iron powder, thereby reducing the residence time of the iron powder inside the feed hopper 10. At the same time, the two scraper rods 8 scrape the inside of the feed hopper 10, reducing the adhesion of iron powder inside the feed hopper 10. This effectively prevents the iron powder from accumulating inside the feed hopper 10, thus avoiding blockage.

[0028] Reference Figure 5 As shown, a screening mechanism is installed inside the screening box 1. The screening mechanism includes a vibrating box 12, which is installed inside the screening box 1. A vibration motor 11 is installed on one side of the vibration box 12, and the vibration motor 11 passes through the screening box 1. A first screening plate 13 and a second screening plate 14 are fixedly connected to the inside of the vibration box 12. The first screening plate 13 is positioned above the second screening plate 14. A plurality of springs 15 are fixedly connected to the bottom of the vibration box 12, and a support plate 16 is fixedly connected to the bottom of the springs 15. The support plate 16 is welded and fixed to the inside of the screening box 1. The vibration motor 11 can drive the vibration box 12 to vibrate. The multiple springs 15 can provide auxiliary force for the vibration of the vibration box 12, so that the first screening plate 13 and the second screening plate 14 inside the vibration box 12 can screen iron powder of different fineness, thereby maintaining the uniformity and consistency of iron powder before entering the processing equipment, which helps to improve processing efficiency and product quality.

[0029] Reference Figure 2 and 3As shown, a first feeding port 17 is connected to one side of the vibrating box 12, and a second feeding port 18 is connected to the other side of the vibrating box 12. Both the first feeding port 17 and the second feeding port 18 are fixedly connected to the vibrating box 12. A second motor 19 is installed on one side of the screening box 1. A rotating shaft 20 is fixedly connected to the output end of the second motor 19. A second spiral blade 21 is welded to the outside of the rotating shaft 20. A third feeding port 22 is connected to one side of the screening box 1. The second motor 19 drives the rotating shaft 20 to rotate, so that the rotating shaft 20 drives the second spiral blade 21 to rotate, thereby continuously conveying the iron powder inside the screening box 1 to the third feeding port 22. The first feeding port 17, the second feeding port 18 and the third feeding port 22 can discharge iron powder of different fineness separately, which is convenient for conveying iron powder of different fineness to different processing equipment as needed.

[0030] Working principle of this utility model: This utility model designs a feeding mechanism for iron powder processing equipment, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when iron powder needs to be fed, the iron powder is first poured into the feeding hopper 10. Then, the first motor 4 is started, and the first motor 4 drives the first gear 5 to rotate, so that the first gear 5 can mesh and drive the second gear 6 to rotate. The rotation of the second gear 6 can drive the gear disk 7 to rotate, so that the gear disk 7 can drive the first spiral blade 9 to rotate inside the feeding cylinder 3. Using the spiral action of the first spiral blade 9, the iron powder inside the feeding cylinder 3 can be quickly conveyed downward. At the same time, the rotation of the gear disk 7 can drive the two scraping rods 8 to rotate, so that the two scraping rods 8 can scrape inside the feeding hopper 10, thereby effectively adhering the iron powder to the inner wall of the feeding hopper 10, so that the feeding hopper 10 can maintain continuous feeding, and the iron powder can fall into the screening box 1. Then, the vibration motor 11 is started. Using the lateral vibration action of the vibration motor 11, the vibration motor 11 is connected to the vibration box 1 through a circular opening on one side of the screening box 1. 2. The connection is made so that the vibrating box 12 can vibrate laterally inside the screening box 1. Using the multiple screening holes on the surface of the first screening plate 13, iron powder can be screened above the first screening plate 13. The screened iron powder will fall above the second screening plate 14, and under the action of the vibrating motor 11, the iron powder can be screened again, thus classifying iron powder of different fineness. The iron powder screened by the second screening plate 14 will fall into the inside of the screening box 1. Then, the second motor 19 is started, and the second motor 19 drives the rotating shaft 20, so that the rotating shaft 20 can drive the second spiral blade 21 to rotate inside the screening box 1. The opening on the outside of the screening box 1 is larger than the first feeding port 17 and the second feeding port 18, so that the first feeding port 17 and the second feeding port 18 can vibrate with the vibration of the vibrating box 12, so that iron powder of different fineness can be discharged from the first feeding port 17, the second feeding port 18 and the third feeding port 22 respectively, which facilitates the separate feeding and processing of iron powder of different fineness according to specific needs.
