Description

Technical Field

[0001] This utility model relates to the field of hammer mills, specifically a feeding device for a hammer mill. Background Technology

[0002] Hammer mills are a common type of equipment used in the pharmaceutical, food, and chemical industries. They produce powder by high-speed shearing and hammering of starch-containing materials or ores, followed by filtration through a stainless steel screen under the drive of a strong airflow. The equipment is equipped with a dust collection device, eliminating powder pollution. It features low temperature, low noise, and high efficiency, making it suitable for crushing dry and brittle materials such as chemical materials and Chinese medicinal herbs.

[0003] In existing technology, hammer mills can effectively crush and pulverize materials, facilitating subsequent processing by workers. However, when using hammer mills, feeding is usually done manually or automatically. Manual feeding is not only inefficient but also increases the workload and fatigue of workers. Automatic feeding can only transport materials and cannot pre-treat or quantitatively add materials during transport. This makes it easier for larger or more humid materials to affect the use of hammer mills, causing materials to adhere more easily to the inner wall of the machine and causing blockages. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, automatic feeding can only transport materials and cannot pre-process or quantitatively add materials during the transport and feeding process. This makes it easy for larger or more humid materials to affect the use of hammer mills, causing problems such as materials adhering more easily to the inner wall of the machine and blockage. This utility model proposes a feeding device for hammer mills.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hammer mill feeding device, including a hammer mill body, a feeding bin fixedly connected to the top of the hammer mill body, a screening plate and a feeding plate slidably connected to the inner cavity of the feeding bin, a connecting plate fixedly connected between the screening plate and the feeding plate, and a quantitative mechanism and a screening mechanism provided in the inner cavity of the hammer mill body;

[0006] The metering mechanism includes a servo motor, one side of which is fixedly connected to one side of the feeding hopper. The output end of the servo motor passes through the feeding hopper and is fixedly connected to an incomplete gear. A driven gear is rotatably connected to the inner cavity of the feeding hopper. The teeth of the driven gear mesh with the teeth of the incomplete gear. A rotating ring block is fixedly connected to one side of the driven gear. A connecting ring block is fixedly connected to one side of the rotating ring block. A drive rod is rotatably connected to the surface of the connecting ring block. An mounting ring block is rotatably connected to the inner cavity of the drive rod. A limit block is fixedly connected to the inner cavity of the feeding hopper. A moving plate is slidably connected to the inner cavity of the limit block. One side of the moving plate is rotatably connected to one end of the mounting ring block.

[0007] Preferably, the screening mechanism includes a connecting shaft, one end of which is fixedly connected to one side of an incomplete gear, a cam is fixedly connected to the surface of the connecting shaft, a bottom rod is fixedly connected to the bottom of the feeding plate, a connecting wheel is rotatably connected to the inner cavity of the bottom rod, and a spring is fixedly connected to the inner cavity of the feeding bin, one end of which is fixedly connected to the bottom of the feeding plate.

[0008] Preferably, the inner cavity of the feeding hopper is fixedly connected to an air outlet pipe, the surface of the air outlet pipe is fixedly connected to an air pump, one end of the air pump is fixedly connected to a heating chamber, the inner cavity of the heating chamber is fixedly connected to a heating plate, and the inner cavity of the heating plate is fixedly connected to an air extraction pipe.

[0009] Preferably, a fixing rod is fixedly connected to the inner cavity of the feeding hopper, and a limiting groove is formed on one side of the bottom rod, with the inner cavity of the limiting groove slidably connected to the surface of the fixing rod.

[0010] Preferably, the inner cavity of the feeding hopper is provided with a sliding groove, and a slider is fixedly connected to one side of the feeding plate, the surface of the slider being slidably connected to the inner cavity of the sliding groove.

[0011] Preferably, a limiting block is fixedly connected to the inner cavity of the feeding hopper, and the inner cavity of the limiting block is rotatably connected to the surface of the connecting shaft.

[0012] Preferably, a reinforcing block is fixedly connected to the bottom of the feeding plate, and the inner cavity of the reinforcing block is fixedly connected to the inner cavity of the bottom rod.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a servo motor to drive an incomplete gear and a connecting shaft to rotate. The rotation of the incomplete gear drives a rotating ring block, which in turn pushes or pulls a moving plate in intermittent reciprocating motion via a drive rod. The rotating ring block, in turn, drives a cam to rotate via the connecting shaft, achieving continuous vibration of the screening plate and the feeding plate. This achieves the functions of screening and conveying materials. When materials are fed into the hammer mill, they are screened, quantitatively fed, and dried during the conveying process. This reduces the likelihood of the hammer mill malfunctioning or experiencing reduced efficiency due to untreated materials. It also solves the problem that automatic feeding systems only transport materials without pre-treatment or quantitative addition, which can negatively impact the operation of larger or more humid materials, causing them to adhere more easily to the inner wall of the machine and leading to blockages.

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] This application discloses a feeding device for a hammer mill. (Refer to...) Figure 1 and Figure 4 A hammer mill feeding device includes a hammer mill body 1, a feeding bin 2 fixedly connected to the top of the hammer mill body 1, a screening plate 4 and a feeding plate 5 slidably connected to the inner cavity of the feeding bin 2, a connecting plate 7 fixedly connected between the screening plate 4 and the feeding plate 5, and a quantitative mechanism 6 and a screening mechanism 8 provided in the inner cavity of the hammer mill body 1.

[0027] The metering mechanism 6 includes a servo motor 601. One side of the servo motor 601 is fixedly connected to one side of the feeding bin 2. The output end of the servo motor 601 passes through the feeding bin 2 and is fixedly connected to an incomplete gear 602. A driven gear 603 is rotatably connected to the inner cavity of the feeding bin 2. The teeth of the driven gear 603 mesh with the teeth of the incomplete gear 602. A rotating ring block 604 is fixedly connected to one side of the driven gear 603. A connecting ring block 605 is fixedly connected to one side of the rotating ring block 604. A drive rod 606 is rotatably connected to the surface of the connecting ring block 605. An mounting ring block 607 is rotatably connected to the inner cavity of the drive rod 606. A limit block 609 is fixedly connected to the inner cavity of the feeding bin 2. A moving plate 608 is slidably connected to the inner cavity of the limit block 609. One side of the moving plate 608 is rotatably connected to one end of the mounting ring block 607.

[0028] The hammer mill body 1 effectively crushes materials, while the feeding hopper 2 uses its internal screening plate 4 and feeding plate 5 to screen and quantitatively add materials. The screening plate 4 mainly works with the screening mechanism 8 to achieve screening, while the feeding plate 5 works with the quantitative mechanism 6 to achieve quantitative feeding. The connecting plate 7 connects the screening plate 4 and the feeding plate 5, allowing the feeding plate 5 to smoothly drive the screening plate 4 to achieve screening when it reciprocates up and down. The servo motor 601 drives the incomplete gear 602 to rotate during operation. Through the meshing of the incomplete gear 602 and the driven gear 603, the driven gear 603 and the rotating ring block 604 are rotated. The mounting ring 607 can be pulled by connecting the connecting ring 605 and the drive rod 606. At the same time, the sliding connection between the limiting block 609 and the moving plate 608 allows the mounting ring 607 to smoothly drive the moving plate 608 to move up and down intermittently when it is pulled or pushed. The intermittent up and down movement of the moving plate 608 can intermittently block the material on the top of the feeding plate 5. When the moving plate 608 blocks the screened material, the material will not be easily added into the interior of the hammer mill body 1. When it no longer blocks the material, the material can be added, thereby realizing the quantitative filling function inside the hammer mill body 1. At the same time, the inner cavity of the feeding plate 5 is slidably connected to the surface of the moving plate 608.

[0029] Reference Figure 4 and Figure 5 The screening mechanism 8 includes a connecting shaft 801, one end of which is fixedly connected to one side of the incomplete gear 602. A cam 802 is fixedly connected to the surface of the connecting shaft 801. A bottom rod 803 is fixedly connected to the bottom of the feeding plate 5. A connecting wheel 804 is rotatably connected to the inner cavity of the bottom rod 803. A spring 805 is fixedly connected to the inner cavity of the feeding bin 2. One end of the spring 805 is fixedly connected to the bottom of the feeding plate 5. When the incomplete gear 602 rotates, it can smoothly drive the cam 802 to rotate through the connecting shaft 801. When the cam 802 rotates, it can push the bottom rod 803 through the connecting wheel 804, thereby vibrating the feeding plate 5. At this time, due to the setting of the spring 805 and the connection between the screening plate 4, the feeding plate 5 and the connecting plate 7, the screening plate 4 and the feeding plate 5 can move together. Through the continuous rotation of the cam 802, the screening plate 4 and the feeding plate 5 are continuously vibrated, so that the screening plate 4 can screen the material, and the feeding plate 5 can convey the material through vibration.

[0030] Reference Figure 2 and Figure 7An air outlet pipe 14 is fixedly connected to the inner cavity of the feeding hopper 2. An air pump 15 is fixedly connected to the surface of the air outlet pipe 14. A heating chamber 16 is fixedly connected to one end of the air pump 15. A heating plate 17 is fixedly connected to the inner cavity of the heating chamber 16. An air extraction pipe 18 is fixedly connected to the inner cavity of the heating plate 17. The air pump 15 can pump external air into the interior of the heating chamber 16 through the air extraction pipe 18 and pump the interior of the heating chamber 16 into the air outlet pipe 14, thereby achieving the intake of external air. The heating plate 17 can heat the air entering the interior of the heating chamber 16, so that the air outlet pipe 14 can continuously blow hot air into the interior of the hammer mill body 1, thereby drying the material through hot air. At the same time, due to the setting of the metering mechanism 6, the material will be added in a metered manner, thereby increasing the time that the material stays on the top of the feeding plate 5, and thus increasing the effect of the material being dried by hot air.

[0031] Reference Figure 5 and Figure 7 The inner cavity of the feeding hopper 2 is fixedly connected to a fixed rod 9. A limiting groove 10 is opened on one side of the bottom rod 803. The inner cavity of the limiting groove 10 is slidably connected to the surface of the fixed rod 9. The fixed rod 9 can limit the vibration of the bottom rod 803 and the feeding plate 5 through the connection between itself and the limiting groove 10, so that the bottom rod 803 and the feeding plate 5 are not prone to displacement or large-scale shaking due to the elastic reset of the spring 805.

[0032] Reference Figure 6 The inner cavity of the feeding bin 2 is provided with a sliding groove 11. A slider 12 is fixedly connected to one side of the feeding plate 5. The surface of the slider 12 is slidably connected to the inner cavity of the sliding groove 11. The connection between the slider 12 and the sliding groove 11 makes the feeding plate 5 more stable when it is vibrating and feeding by the drive of the cam 802, and also increases the stability of the screening plate 4 when screening materials.

[0033] Reference Figure 4 and Figure 5 The inner cavity of the feeding bin 2 is fixedly connected to a limiting block 3. The inner cavity of the limiting block 3 is rotatably connected to the surface of the connecting shaft 801. The limiting block 3 can support and limit the rotation of the connecting shaft 801 through its connection with the feeding bin 2, so that the connecting shaft 801 is not easy to tilt or shake during rotation.

[0034] Reference Figure 7 A reinforcing block 13 is fixedly connected to the bottom of the feeding plate 5. The inner cavity of the reinforcing block 13 is fixedly connected to the inner cavity of the bottom rod 803. The reinforcing block 13 can reinforce the connection between the reinforcing block 13 and the bottom rod 803 through its connection with the feeding plate 5 and the bottom rod 803, so that the bottom rod 803 is not prone to shaking or breaking at the connection with the feeding plate 5 due to long-term vibration of the feeding plate 5.

[0035] Working Principle: When using this device, the operator adds material into the feeding hopper 2. After placement, the servo motor 601, heating plate 17, and vacuum pump 15 are activated. The servo motor 601 smoothly drives the incomplete gear 602, which in turn drives the connecting shaft 801 to rotate. As the connecting shaft 801 rotates, it smoothly pushes the connecting wheel 804 and the bottom rod 803 via the cam 802. The bottom rod 803, after being pushed, moves upward, causing the screening plate 4 and the feeding plate 5 to move upward together. After rotating to a certain angle, the cam 802 releases its push on the bottom rod 803, at which point the screening plate 4 and the feeding plate 5 will... The cam 802 is reset, and the continuous rotation of the cam 802 can achieve continuous vibration of the screening plate 4 and the feeding plate 5 to screen the material. The rotation of the incomplete gear 602 can smoothly drive the rotating ring block 604 to rotate by meshing with the driven gear 603. When the rotating ring block 604 rotates, it can drive the connecting ring block 605 to rotate eccentrically. By using the rotation of the connecting ring block 605 and the connection between the mounting ring block 607 and the drive rod 606 and the moving plate 608, the moving plate 608 can be moved up and down intermittently. When the moving plate 608 is in the upward state, it can block the material, making it difficult for the material to slide into the interior of the hammer mill body 1 through the vibration of the feeding plate 5.

[0036] When the moving plate 608 is in the downward state, the restriction and obstruction of the material can be removed. At this time, the material can slide down into the interior of the hammer mill body 1 through the vibration of the feeding plate 5. During the screening and conveying of the material by the screening plate 4 and the feeding plate 5, the air pump 15 can draw the external air into the air outlet pipe 14 through its own operation. During the extraction process, the air is heated by the operation of the heating plate 17, so that the air outlet pipe 14 can blow out the hot air, thereby realizing the heating and drying of the material during the feeding process.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
