Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a dust-proof auxiliary feeding device for cemented carbide processing. Background Technology

[0002] Due to its high hardness and high wear resistance, cemented carbide is widely used in cutting tools, mining tools and other fields. In the process of cemented carbide processing, it is often necessary to crush, grind or screen it to obtain the material with the required particle size. However, during the feeding and transfer of cemented carbide materials, fine dust is easily generated due to friction and collision between particles, and this dust will fly around during the feeding process.

[0003] Current feeding devices often connect to dust removal equipment via pipes when feeding cemented carbide materials to absorb and treat flying dust. However, the connection between the dust suction pipe and the feeding container is often fixed, making it difficult for some dust far from the pipe inlet to be sucked in, thus affecting the dust prevention effect. Therefore, in order to solve the above defects, the inventors propose a dust prevention auxiliary feeding device for cemented carbide processing. Utility Model Content

[0004] The main purpose of this utility model is to provide a dust-proof auxiliary feeding device for cemented carbide processing, which can effectively solve the problem that the connection between the dust suction pipe and the feeding container of the existing feeding device is often fixed, making it difficult for some dust far away from the pipe inlet to be sucked in by the pipe, thus affecting the dust-proof effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Both guide rods are slidably connected to the outer top surface of the feeding hopper. A dust suction assembly is provided on one side of the top surface of the base.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] This utility model discloses a dust-proof auxiliary feeding device for cemented carbide machining, such as... Figure 1-5 As shown, it includes a base 1, a motor 101 located on one side of the top surface of the base 1, a reducer 102 located on one side of the top surface of the base 1, a feed pipe 2 fixedly installed on the top surface of the base 1, and a feed hopper 3 fixedly installed at the inlet of the feed pipe 2, the feed hopper 3 being connected to the feed pipe 2.

[0023] The output shaft of motor 101 is fixedly connected to the input shaft of reducer 102. The inside of feed pipe 2 is rotatably connected to screw conveyor 201, and the output shaft of reducer 102 is fixedly connected to screw conveyor 201. A conveying pipe 8 is fixedly installed on one side of feed pipe 2.

[0024] After the motor 101 starts, the output shaft rotates at high speed, and the power is transmitted to the input shaft of the reducer 102 through the coupling. The reducer 102 converts the high-speed rotation into low-speed, high-torque output through multi-stage gear meshing, which ultimately drives the screw conveyor 201 to rotate at a suitable speed. The cemented carbide material in the feed hopper 3 will continuously enter through the connection port of the feed pipe 2. When the screw conveyor 201 rotates, its spiral blades will "grab" the material close to the axis and push it axially through the rotation of the blades. The cemented carbide material is continuously pushed towards the discharge port with the rotation of the spiral blades, and finally leaves the feed pipe 2 and enters the conveying pipe 8. The conveying pipe 8 is connected to the inlet of the processing equipment, which completes the feeding of cemented carbide material.

[0025] An electric push rod 301 is fixedly installed on the outer top surface of the feed hopper 3, and the output end of the electric push rod 301 extends into the feed hopper 3 and is fixedly installed with a suction pipe 303. Multiple suction heads 304 are fixedly installed on one side of the suction pipe 303. Two guide rods 302 are fixedly installed on the outer surface of the suction pipe 303, and both guide rods 302 are slidably connected to the outer top surface of the feed hopper 3. A dust collection assembly is provided on one side of the top surface of the base 1.

[0026] The electric actuator 301 can push the suction pipe 303 to move up and down, thereby adjusting the height of the multiple suction heads 304. When the suction pipe 303 moves up and down, it will drive the two guide rods 302 to move.

[0027] The length of the suction pipe 303 is matched with the length of the feed hopper 3. By raising and lowering multiple suction heads 304, the inside of the feed hopper 3 can be effectively vacuumed.

[0028] The dust collection assembly includes a centrifugal fan 4 fixedly installed on one side of the top surface of the base 1. When the fan 4 is powered on, the motor 101 of the fan 4 drives the impeller to rotate. The gas enters the center of the impeller axially and is thrown to the outer edge of the impeller by the blades, increasing its kinetic energy. Then the gas enters the volute. Due to the expansion of the cross-sectional area, the kinetic energy is converted into static pressure energy and finally discharged axially from the outlet of the volute.

[0029] A dust collector 6 is fixedly installed on one side of the top surface of the base 1. A connecting pipe 5 is fixedly connected between the inlet of the exhaust fan 4 and the outer top surface of the dust collector 6. An exhaust pipe 9 is fixedly installed at the outlet of the exhaust fan 4. The exhaust fan 4 draws the dust in the feed hopper 3 into the dust collector 6 through the connecting pipe 5 and the stainless steel corrugated pipe 7. The airflow after being treated by the dust collector 6 will be discharged through the exhaust pipe 9.

[0030] A stainless steel corrugated pipe 7 is fixedly installed on one side of the outer surface of the dust collector 6, and the end of the stainless steel corrugated pipe 7 away from the dust collector 6 extends into the interior of the feed hopper 3 and is fixedly connected to the suction pipe 303. The stainless steel corrugated pipe 7 can deform as the suction pipe 303 rises and falls.

[0031] A feed inlet 3021 is fixedly installed on the top surface of the feed hopper 3. Two baffles 3023 are hinged inside the feed inlet 3021. Two torsion springs 3022 are fixedly installed on both sides of the inside of the feed inlet 3021, and the four torsion springs 3022 are fixedly connected to the two baffles 3023 respectively. Two baffles 3024 are fixedly installed on both sides of the inside of the feed inlet 3021, and the two baffles 3024 are located above the two baffles 3023 respectively. Through the elastic force of the torsion springs 3022, the two baffles 3023 will abut against the bottom surface of the two baffles 3024 in the normal state, presenting a horizontal state, so as to block the feed inlet 3021.

[0032] When the worker pours the cemented carbide material into the feed inlet 3021, if the weight of the cemented carbide material falling on the baffle 3023 is greater than the elastic force of the torsion spring 3022, the two baffles 3023 can overcome the elastic force of the torsion spring 3022 and rotate. The cemented carbide material will then fall into the feed hopper 3 through the gap between the two baffles 3023. After the cemented carbide material falls into the feed hopper 3, the two baffles 3023 will be reset by the elastic force of the torsion spring 3022, thereby effectively preventing dust from flying out of the feed hopper 3.

[0033] The bottom surface of the dust collector 6 is threaded with a connecting cover 603, and the top surface of the dust collector 6 is threaded with a metal ring 602. A filter bag 601 is fixedly installed on the outer surface of the metal ring 602. The dust-laden airflow entering the dust collector 6 will enter the filter bag 601. During the process, the dust inside will be intercepted and filtered. By rotating the connecting cover 603, the filter bag 601 can be removed, and the dust accumulated inside the dust collector 6 can be replaced or cleaned.

[0034] The working principle of this utility model is as follows: First, the worker's feeding pipe 8 is connected to the feed inlet 3021 of the cemented carbide processing equipment. Then, the cemented carbide material is poured into the feed inlet 3021. When the weight of the cemented carbide material falling on the baffle 3023 is greater than the elastic force of the torsion spring 3022, the two baffles 3023 can overcome the elastic force of the torsion spring 3022 and rotate. The cemented carbide material will fall into the feed hopper 3 through the gap between the two baffles 3023. After the cemented carbide material falls into the feed hopper 3, the two baffles 3023 will be reset by the elastic force of the torsion spring 3022, thereby effectively preventing the dust in the feed hopper 3 from flying out.

[0035] Afterwards, the staff started the exhaust fan 4. The exhaust fan 4 sucked the dust in the feed hopper 3 into the dust collector 6 through the connecting pipe 5 and the stainless steel corrugated pipe 7. The filter bag 601 filtered and intercepted the dust-laden airflow, which played a role in preventing dust from being stirred up. The electric push rod 301 can push the suction pipe 303 to rise and fall inside the feed hopper 3. With the help of multiple suction heads 304 on the suction pipe 303, the dust in the feed hopper 3 can be effectively absorbed.

[0036] The motor 101 can then be started. The output shaft of the motor 101 rotates at high speed, and the power is transmitted to the input shaft of the reducer 102 through the coupling. The reducer 102 converts the high-speed rotation into low-speed, high-torque output through multi-stage gear meshing, which ultimately drives the screw conveyor 201 to rotate at a suitable speed for feeding.

The specific selection calculation method, circuit connection method and control method all adopt the existing technology in this field, and the power supply is also common knowledge in this field, so it will not be described in detail.
