Description

Technical Field

[0001] This utility model relates to a vibratory feeder, specifically a cemented carbide vibratory feeder, and belongs to the field of feeder technology. Background Technology

[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals (such as tungsten carbide and titanium carbide) and binder metals (such as cobalt and nickel) through powder metallurgy. It possesses a series of excellent properties, including high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance, especially its high hardness and wear resistance. Due to its superior physical properties, cemented carbide plays a vital role in industrial manufacturing, particularly in applications requiring high wear resistance and high hardness. In the production process of cemented carbide, a vibrating feeder uniformly and precisely feeds the raw materials into the melting furnace, which is the first step in the entire smelting process. Because the raw materials need to be fed into the high-temperature furnace, which is inaccessible to humans, specialized equipment is required to accomplish this task.

[0003] Existing cemented carbide vibratory feeders typically use casters to roll along tracks to bring the feeder close to a high-temperature furnace. However, since the casters cannot be fixed by themselves, they will wobble during operation, requiring manual fixation when the feeder approaches the furnace. The high temperature of the furnace causes discomfort to the workers and reduces the practicality of the device. To address these issues, we provide a cemented carbide vibratory feeder. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a cemented carbide vibratory feeder, the specific technical solution of which is as follows:

[0005] A cemented carbide vibratory feeder includes a guide rail, a base plate slidably connected to the upper surface of the guide rail, a vibratory box disposed above the base plate, a feed inlet slidably connected to the inner wall of the vibratory box, a reset mechanism mounted on the outer surface of the base plate, a limit mechanism mounted on the outer surface of the guide rail, and a motor mounted on one end of the guide rail.

[0006] Preferably, the reset mechanism includes a lower support plate, which is fixedly installed on the outer surface of the base plate, and an upper support plate is provided above the lower support plate. The upper support plate is fixedly installed on the outer surface of the feed inlet, and the upper support plate and the lower support plate are connected to each other by a first spring.

[0007] Preferably, the limiting mechanism includes a limiting block, a second spring is installed inside the limiting block, a locking block is installed at the other end of the second spring, a locking rod is provided above the limiting block, and the top of the locking rod is fixedly installed to the outer surface of the feed inlet.

[0008] Preferably, a reducer is installed at the output end of the motor, a threaded rod is fixedly installed at the output end of the reducer, a slider is fixedly installed on the bottom surface of the base plate, the outer surface of the threaded rod is threadedly connected to the inner wall of the slide, and the other end of the threaded rod is slidably connected to the outer surface of the guide rail.

[0009] Preferably, a third spring is installed on the bottom surface of the vibration box, and the other end of the third spring is fixedly installed to the upper surface of the base plate.

[0010] Preferably, a vibration motor is installed on the bottom surface of the vibration box, and a discharge port is fixedly installed on the outer surface of the vibration box.

[0011] Preferably, there are two limiting mechanisms, symmetrically distributed on both sides of the feed inlet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This cemented carbide vibratory feeder, through the cooperation of guide rails, feed inlet, first spring, locking rod, locking block, second spring, and limit block, operates by moving the feeder to a position close to the furnace via a motor. Cemented carbide is then fed into the feed inlet. Due to the weight of the cemented carbide, gravity compresses the first spring in the reset mechanism, causing the feed inlet to slide down. The locking rod, mounted on the outer surface of the feed inlet, also moves down. This downward movement causes two locking blocks to move in opposite directions against the force of the second spring. The outer surface of the locking rod has recesses. When the locking rod reaches the bottom of the positioning groove, the locking blocks spring back out under the action of elasticity, closely contacting the recesses on the locking rod, thus limiting the device's position without manual fixing. This reduces shaking during operation, facilitating the use of the device and effectively increasing its practicality.

[0014] 2. This cemented carbide vibrating feeder, through the cooperation between the feed inlet, upper support plate, lower support plate, and first spring, allows all the cemented carbide inside the feed inlet to enter the furnace through the vibrating box after feeding is completed. At this time, the first spring rebounds upwards to the upper support plate under its own elastic force, and both the upper support plate and the feed inlet move upwards. The clamping plate also moves upwards to release the limit on the device and reset the device. This eliminates the need for manual reset, making the device more convenient to use and further enhancing its practicality. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 — Figure 5 The device includes a guide rail 1, with a limiting mechanism 6 mounted on its outer surface. The limiting mechanism 6 includes a limiting block 601, a second spring 602 installed inside the limiting block 601, and a locking block 603 mounted on the other end of the second spring 602. A locking rod 604 is positioned above the limiting block 601, with its top fixed to the outer surface of the feed inlet 4. Two limiting mechanisms 6 are symmetrically distributed on both sides of the feed inlet 4. During use, the device moves along the guide rail 1 to a position close to the furnace. A baffle is installed at one end of the guide rail 1 to prevent the device from exceeding its movement limits. A positioning groove is provided on the limiting block 601, directly opposite the locking rod 604. Inside the limiting block 601, two locking blocks 603 are positioned opposite each other, their outer surfaces tightly contacting each other under the elastic force of the second spring 602. When the device... When moved to the corresponding position, hard alloy is placed into the feed inlet 4. The hard alloy will fill the feed inlet 4 and move downward under the vibration of the device. Due to the heavy weight of the hard alloy, it will press the first spring 503 in the reset mechanism 5 under the action of gravity, causing the feed inlet 4 to slide down. The locking rod 604 installed on the outer surface of the feed inlet 4 will also move down. The downward movement of the locking rod 604 causes the two locking blocks 603 to overcome the elastic force of the second spring 602 and move in the opposite direction. The outer surface of the locking rod 604 is provided with a recess. When the locking rod 604 moves down to the bottom of the positioning groove, the locking blocks 603 will pop out again under the action of elastic force and stick to the recess on the locking rod 604, thereby realizing the limitation of the device. There is no need to rely on manual fixation. At the same time, it reduces the shaking of the vibrating feeder during operation, facilitates the use of the device, and increases the practicality of the device.

[0023] A base plate 2 is slidably connected to the upper surface of the guide rail 1. A vibrating box 3 is installed above the base plate 2. A feed inlet 4 is slidably connected to the inner wall of the vibrating box 3. A vibrating motor 12 is installed on the bottom surface of the vibrating box 3. A discharge port 13 is fixedly installed on the outer surface of the vibrating box 3. A third spring 11 is installed on the bottom surface of the vibrating box 3. The other end of the third spring 11 is fixedly installed to the upper surface of the base plate 2. The upper surface of the base plate 2 and the bottom surface of the vibrating box 3 are connected to each other through the third spring 11. The vibrating motor 12 is installed on the bottom surface of the base plate 2. When the vibrating motor 12 is working, the vibration generated causes the vibrating box 3 to vibrate. The third spring 11 reduces the excessive vibration generated by the device, making the device more stable during operation, thereby improving the practicality of the device. Hard alloy enters the vibrating box 3 through the feed inlet 4 and leaves the vibrating box 3 through the discharge port 13 and enters the high-temperature furnace.

[0024] A reset mechanism 5 is installed on the outer surface of the base plate 2. The reset mechanism 5 includes a lower support plate 501, which is fixedly installed on the outer surface of the base plate 2. An upper support plate 502 is provided above the lower support plate 501 and is fixedly installed on the outer surface of the feed inlet 4. The upper support plate 502 and the lower support plate 501 are connected to each other by a first spring 503. When the device moves to a designated position next to the molten metal, it puts hard alloy into the feed inlet 4. Under the gravity of the hard alloy, the feed inlet 4 will press the upper support plate 502, and the upper support plate 502 will press the first spring 503. 3. Then, the first spring 503 contracts, and the upper support plate 502 and the feed port 4 both move downward. At the same time, the downward movement drives the clamping plate in the limiting mechanism 6 to move downward, so that the clamping plate inserts into the inside of the limiting block 601 to complete the limiting of the device. After the feeding is completed, all the hard alloy inside the feed port 4 enters the furnace through the vibration box 3. At this time, the first spring 503 rebounds upward and the upper support plate 502 moves upward. The upper support plate 502 and the feed port 4 both move upward, and the clamping plate also moves upward to release the limiting of the device and play a role in resetting the device, thereby facilitating the use of the device.

[0025] A motor 7 is mounted on one end of the guide rail 1. A reducer 8 is mounted on the output end of the motor 7. A threaded rod 9 is fixedly mounted on the output end of the reducer 8. A slider 10 is fixedly mounted on the bottom surface of the base plate 2. The outer surface of the threaded rod 9 is threadedly connected to the inner wall of the slider. The other end of the threaded rod 9 is slidably connected to the outer surface of the guide rail 1. When the motor 7 starts, it drives the reducer 8 to run. The threaded rod 9 is mounted on the output end of the reducer 8. The reducer 8 converts the high speed of the motor 7 into the low speed of the threaded rod 9, thereby increasing the torque transmitted by the motor 7. The outer surface of the threaded rod 9 is slidably connected to the inner wall of the slider 10. The rotation of the threaded rod 9 drives the slider 10 to move. The slider 10 is mounted on the bottom surface of the base plate 2. Thus, the operation of the motor 7 can drive the base plate 2 to move, thereby driving the device to move. The motor 7 is located at one end of the threaded rod 9. The threaded rod 9 and the guide rail 1 shown in the figure are only part of the main body. The length of the threaded rod 9 and the guide rail 1 should be set according to the actual use, and the positions of the motor 7 and the reducer 8 should be fixed at the same time.

[0026] In use, this invention works as follows: Motor 7 moves the feeder to a position close to the furnace, and cemented carbide is placed into the feed inlet 4. Due to the weight of the cemented carbide, gravity compresses the first spring 503 in the reset mechanism 5, causing the feed inlet 4 to slide down. The locking rod 604 mounted on the outer surface of the feed inlet 4 also moves down accordingly. The downward movement of the locking rod 604 causes the two locking blocks 603 to move in opposite directions against the elastic force of the second spring 602. The outer surface of the locking rod 604 has a recess. When the locking rod 604 reaches the bottom of the positioning groove, the locking blocks 603 will spring back out under the action of elasticity, tightly contacting the recess on the locking rod 604. The pit allows for the limiting of the device without manual fixing, reducing shaking during operation and facilitating its use. This significantly increases the device's practicality. Furthermore, after feeding, all the hard alloy inside the feed inlet 4 enters the furnace through the vibrating box 3. At this point, the first spring 503 rebounds upwards onto the upper support plate 502 under its own elastic force. Both the upper support plate 502 and the feed inlet 4 move upwards, and the clamping plate also moves upwards, releasing the device's limiting and resetting it. This eliminates the need for manual resetting, further enhancing the device's usability.
