Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to an anti-clogging feeder for powder metallurgy. Background Technology

[0002] Powder metallurgy is a process technology that produces metal powders or uses metal powders (or mixtures of metal powders and non-metal powders) as raw materials, and manufactures metal materials, composite materials and various types of products through forming and sintering. In the powder metallurgy process, the feeder plays a very important role, and the stability and continuity of the feeder directly affect the quality of the products and the production efficiency.

[0003] Traditional feeders often experience clogging problems when handling powdery materials. Due to the friction between powder particles and their susceptibility to environmental humidity, static electricity, and other factors, they easily accumulate and clump at the hopper and discharge port, leading to poor feeding or even complete blockage. This not only requires frequent shutdowns for cleaning, increasing production costs, but also causes production interruptions and affects production schedules. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging feeder for powder metallurgy to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging feeder for powder metallurgy, comprising a movable frame, an installation frame fixedly installed on the top of the movable frame, a fixed bucket fixedly installed on the inner side of the installation frame, a stirring anti-clogging mechanism provided inside the fixed bucket, and a conveying and feeding mechanism provided at the bottom of the fixed bucket.

[0006] The conveying and feeding mechanism includes a conveying component and a quantitative feeding component. The conveying component is located at the bottom of the fixed barrel, and the quantitative feeding component is located outside the conveying component.

[0007] Preferably, the stirring anti-clogging mechanism includes a mixing tank, which is rotatably mounted inside a fixed tank. A gear ring is fixedly mounted on the top of the mixing tank. A motor A is fixedly mounted on the outside of the fixed tank. A gear is fixedly mounted on one side of the output shaft of the motor A extending to the gear ring. A mounting plate is fixedly mounted on the outside of the mounting frame. A motor B is fixedly mounted on the top of the mounting plate. A stirring rod A is fixedly mounted on one end of the motor B extending through the mounting plate to the inside of the mixing tank. A stirring rod B is rotatably mounted on the top of the mounting plate. A belt is directly driven between the top of the stirring rod B and the output end of the motor B.

[0008] Preferably, the gear is located outside the fixed barrel, and the gear is meshed with the gear ring.

[0009] Preferably, the conveying assembly includes a conveying pipe, which is fixedly installed at the bottom of a fixed barrel. A motor C is fixedly installed on the inner side of the conveying pipe. A partition is fixedly installed on the inner side of the conveying pipe near the motor C. A spiral blade is fixedly installed at the output end of the motor C, passing through the partition. A pressing rod A is fixedly installed on the outside of the spiral blade. A fixed frame A is fixedly installed on the end of the conveying pipe away from the motor C. A pressing rod B is slidably installed on the inner side of the fixed frame A. A rubber piston is fixedly installed on the outside of the pressing rod B. A spring A is fixedly installed between the pressing rod B and the fixed frame A.

[0010] Preferably, the quantitative feeding assembly includes a feeding pipe, which is fixedly installed outside the conveying pipe. A limit stop rod is slidably installed on the inner side of the feeding pipe. A fixing frame B is fixedly installed on the inner side of the feeding pipe. A spring B is fixedly installed between the fixing frame B and the limit stop rod. A feeding port is opened at the bottom of the feeding pipe.

[0011] Preferably, the extrusion rod B is located inside the conveying pipe, and the extrusion rod B is engaged with the extrusion rod A.

[0012] Preferably, the size of the rubber piston is in close contact with the inner side of the feed tube, and the rubber piston and the feed tube are slidably connected.

[0013] Compared with the prior art, this utility model provides an anti-clogging feeder for powder metallurgy, which has the following beneficial effects: 1. This anti-clogging feeder for powder metallurgy uses a stirring anti-clogging mechanism. When motor B is turned on, the powder in the mixing tank is stirred in both directions, effectively avoiding accumulation and clogging caused by inadequate mixing, and keeping the powder in a good flow state. When motor A is turned on, the mixing tank is rotated inside the fixed tank, and the direction of rotation is opposite to the stirring direction of the stirring rod. This reverse rotation design further enhances the flowability of the powder in the mixing tank, greatly reduces the possibility of powder accumulation, prevents clogging from the source, and ensures a smooth feeding process.

[0014] 2. This anti-clogging feeder for powder metallurgy uses a conveying and feeding mechanism to transport powder to the vicinity of the feeding pipe via a rotating spiral blade. This drives a rubber piston to push the powder, which not only increases the power of powder conveying but also effectively prevents powder from clogging at the connection between the conveying pipe and the feeding pipe. By pulling the limiting stop rod, the degree of restriction on powder conveying can be changed, thus precisely controlling the time it takes for powder to flow out of the feeding port, thereby achieving quantitative feeding and improving powder utilization.

[0017] 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.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0019] Please see Figure 1-3 During the feeding process, inadequate mixing can lead to accumulation and blockage in the barrel, resulting in slow feeding speed. Therefore, this utility model provides a technical solution: an anti-blocking feeder for powder metallurgy, including a movable frame 1, an installation frame 2 fixedly installed on the top of the movable frame 1, a fixed barrel 3 fixedly installed on the inner side of the installation frame 2, a stirring anti-blocking mechanism 4 inside the fixed barrel 3, and a conveying feeding mechanism 5 at the bottom of the fixed barrel 3.

[0020] The conveying and feeding mechanism 5 includes a conveying component 51 and a quantitative feeding component 52. The conveying component 51 is located at the bottom of the fixed barrel 3, and the quantitative feeding component 52 is located outside the conveying component 51.

[0021] Furthermore, the stirring anti-clogging mechanism 4 includes a mixing tank 41, which is rotatably mounted inside the fixed tank 3. A gear ring 42 is fixedly mounted on the top of the mixing tank 41. A motor A43 is fixedly mounted on the outside of the fixed tank 3. The output shaft of the motor A43 extends to one side of the gear ring 42 and a gear 44 is fixedly mounted thereon. An mounting plate 45 is fixedly mounted on the outside of the mounting bracket 2. A motor B46 is fixedly mounted on the top of the mounting plate 45. The output shaft of the motor B46 extends through the mounting plate 45 to one end inside the mixing tank 41 and a stirring rod A47 is fixedly mounted thereon. A stirring rod B48 is rotatably mounted on the top of the mounting plate 45. A belt 49 is directly driven between the top of the stirring rod B48 and the output end of the motor B46 to facilitate accelerated mixing and stirring, thereby increasing the powder flow rate and making it difficult for the powder to accumulate in the mixing tank 41, thus preventing clogging and achieving rapid material discharge.

[0022] Furthermore, gear 44 is located outside the fixed barrel 3, and gear 44 is meshed with gear ring 42 to facilitate transmission and assist rotation. Example

[0023] Please see Figure 4-5 The powder is conveyed and quantitatively fed to improve utilization efficiency. In conjunction with Embodiment 1, the conveying assembly 51 further includes a conveying pipe 511, which is fixedly installed at the bottom of the fixed bucket 3. A motor C512 is fixedly installed inside the conveying pipe 511. A partition 513 is fixedly installed on the inner side of the conveying pipe 511 near the motor C512. A spiral blade 514 is fixedly installed at the output end of the motor C512, passing through the partition 513. An extrusion rod A518 is fixedly installed on the outside of the spiral blade 514. A fixed frame A515 is fixedly installed on the end of the conveying pipe 511 away from the motor C512. An extrusion rod B519 is slidably installed inside the fixed frame A515. A rubber piston 516 is fixedly installed on the outside of the extrusion rod B519. A spring A517 is fixedly installed between the extrusion rod B519 and the fixed frame A515 to facilitate powder conveying and increase the pushing function to prevent blockage.

[0024] Furthermore, the quantitative feeding component 52 includes a feeding pipe 521, which is fixedly installed on the outside of the conveying pipe 511. A limiting stop rod 522 is slidably installed on the inside of the feeding pipe 521. A fixing frame B524 is fixedly installed on the inside of the feeding pipe 521. A spring B523 is fixedly installed between the fixing frame B524 and the limiting stop rod 522. A feeding port 525 is opened at the bottom of the feeding pipe 521 to facilitate quantitative feeding and improve powder utilization.

[0025] Furthermore, the extrusion rod B519 is located inside the conveying pipe 511, and the extrusion rod B519 is meshed with the extrusion rod A518 for easy transmission.

[0026] Furthermore, the size of the rubber piston 516 fits snugly against the inner side of the feed tube 521, and the rubber piston 516 and the feed tube 521 are slidably connected, which facilitates the pushing of powder and prevents caking and blockage.

[0027] In actual operation, when this device is used, firstly, by pushing the movable frame 1, the device can be easily moved close to the powder storage area. Pre-mixed metal powder is then added into the mixing drum 41. Motor B46 is then turned on, driving the stirring rod A47 inside the mixing drum 41 to rotate. When motor B46 rotates, belt 49 drives the stirring rod B48 on the other side to rotate. The stirring rods A47 and B48 stir each other, mixing the metal powder and achieving a fluid state. Motor A43 is then turned on, driving gear 44 and gear ring 42 to mesh and rotate, causing the mixing drum 41 to rotate inside the fixed drum 3. The rotation direction is opposite to the stirring direction, increasing the fluidity of the powder inside the mixing drum 41 and preventing accumulation and blockage, which would affect the feeding speed. When the powder enters the conveying pipe 511, motor C512 is turned on. The motor C512 drives the spiral blade 514 to rotate, conveying the powder inside the conveying pipe 511 to a position near the discharge pipe 521. When the spiral blade 514 rotates, it drives the extrusion rods A518 and B519 to mesh and extrude, which in turn drives the rubber piston 516 to push the powder at the opening of the discharge pipe 521 to the inside of the discharge pipe 521, improving the conveying effect and preventing the powder from getting stuck at the inlet. After that, the powder is reset by the spring A517 and the pushing is repeated. When it is necessary to control the amount of powder being discharged, the limit stop rod 522 is pulled, causing the limit stop rod 522 to slide along the inside of the fixed frame B524 and move to the outside of the discharge pipe 521. The compression spring B523 makes the inner end of the limit stop rod 522 no longer restrict the conveying of powder. By controlling the time it takes for the powder to flow out of the discharge port 525, the theorem effect is achieved, ensuring more accurate powder discharge and improving powder utilization.
