[0002] Abrasive balls are made by cutting steel wires, which include high-quality steel wires, low-carbon steel wires and stainless steel wires. Before cutting, the steel wires need to be fed through feeding equipment to facilitate the cutting equipment to cut the steel wires into abrasive balls, that is, steel balls. This is a technical revelation for feeding equipment. The following problems were found in the research of feeding equipment: The feeding equipment is driven by a motor to transport the steel wire. Since the steel wire needs to be transported and stored before cutting, dust is easily adhered to the surface during transportation and storage. Therefore, after the steel wire is fed and cut, the abrasive pellets made by cutting need to be cleaned twice, resulting in the feeding equipment being unable to screen the dust on the surface of the steel wire while feeding; At present, CN201611229561.4 in the prior art discloses a steel shot production line, which discloses a screening and feeding device. The quenching pool of the invention is provided with an upwardly protruding cone in the middle, and a centrifuge is installed on the top of the cone. The steel shots thrown out by the centrifuge enter the quenching pool and are collected, and then poured into the feed hopper of the tempering furnace through a material cart, thereby starting the tempering treatment of the steel shots. After the tempering is completed, the steel shots are sent to the second feed hopper through a conveyor belt to start screening, so that the size of the steel shots finally obtained is screened, thereby improving the production efficiency of the steel shots; The present invention can mainly solve the problem that the feeding equipment cannot screen the dust on the surface of the steel wire while feeding.

The specific operation steps are as follows: S1: The wire coil is placed outside the frame, one end of the wire is connected to the cutting device, and the motor drives the frame to rotate; S2: When the wire coil is placed around the outside of the rack, the wire coil is squeezed to one end of the gasket as a whole, and the gasket slides toward one side of the ring through the telescopic rod. As the wire coil outside the rack gradually decreases and the rack rotates to generate centrifugal force, the telescopic rod slides toward one side of the gasket using the centrifugal force, and the gasket can slide toward one side of the wire coil; S3: The frame conveys the steel wire to one end of the cutting device, which can cut the steel wire into abrasive pellets, and the steel wire passes through the internal holes of the screening box; S4: by injecting clean water into the water tank, the clean water enters the interior of the screening box through the drain port at the lower end of the water tank, and at this time the clean water enters the lower end of the interior of the screening box; S5: Clean water enters the screening box.

As the water level inside the screening box rises, clean water can enter the interior of the sponge block through the pipe, and the clean water can wash the dust on the surface of the sponge block. After washing, the clean water falls to the lower end of the hole in the screening box; S7: Since the drain pipe is at the lower end of the screening box, clean water enters the drain pipe and hits the upper end of the sealing plate. The sealing plate moves downward through the sliding rod. At this time, the clean water can flow back to the inside of the screening box through the drain pipe. Beneficial Effects

[0020] 1. When the steel wire coil is placed on the outside of the rack, the steel wire coil is squeezed to one end of the gasket as a whole, and the gasket slides toward one side of the ring through the telescopic rod. As the steel wire coil outside the rack gradually decreases and the rack rotates to generate centrifugal force, the telescopic rod slides toward one side of the gasket using the centrifugal force, and the gasket can slide toward one side of the steel wire coil. The sliding of the gasket can prevent the steel wire coil from being loosened as a whole when the number is small, and at the same time, the sliding of the gasket can further improve the tightness between the steel wire coils; 2. When the clean water enters the screening box and flows to the lower end of the screening box, the sealing plate floats upward through the buoyancy of the clean water. At this time, the sealing plate can slide into the drain pipe. The upward floating of the sealing plate can close the drain pipe, preventing the clean water from directly entering the lower end of the outer side of the screening box through the drain pipe; 3. When the steel wire passes through the side wall of the sponge block, the sponge block can screen the impurities and dust on the surface of the steel wire to prevent dust from adhering to the surface of the grinding balls when the steel wire is cut into grinding balls; 4. As the water level inside the screening box rises, clean water can enter the interior of the sponge block through the pipe, and the clean water can wash away the dust on the surface of the sponge block. After washing, the clean water falls to the lower end of the holes in the screening box. Since the drain pipe is at the lower end of the screening box, the clean water enters the drain pipe and hits the upper end of the sealing plate. The sealing plate moves downward through the sliding rod. At this time, the clean water can flow back to the interior of the screening box through the drain pipe, so that this type of screening and feeding equipment can be recycled during the screening process of impurities.

The sliding of the gasket 202 can prevent the steel wire roll from being loosened as a whole when the number is small, and at the same time, the sliding of the gasket 202 can further improve the tightness between the steel wire rolls. Example 3: Refer to the attached manual Figure 4-5 It can be seen that the difference between Example 3 and Examples 1 and 2 is that baffles 302 surround the holes of the screening box 3 on both sides, and a water tank 301 is connected through the upper end of the screening box 3; Wherein: the baffle 302 is in a circular ring shape, the baffle 302 is located on both sides of the screening box 3, and the steel wire runs through the inside of the baffle 302; A water tank 301, the upper end of which is slidably nested with a sealing cover, a drain port is penetrated at the lower end of the water tank 301, the drain port is connected to the interior of the screening box 3, the volume of the water tank 301 is one half of the internal volume of the screening box 3, and the interior of the water tank 301 is filled with clean water; The lower end of the water tank 301 is penetrated with a drain port, which is connected to the interior of the screening box 3. Figure 5 As shown; Wherein: by injecting clean water into the water tank 301, the clean water enters the interior of the screening box 3 through the drainage port at the lower end of the water tank 301, and at this time, the clean water enters the lower end of the interior of the screening box 3; Example 4: Refer to the attached manual Figure 4-8 It can be seen that the difference between Example 4 and Examples 1-3 is that sponge blocks 4 are provided on both sides of the hole of the screening box 3, a pipe 401 is penetrated through one end of the sponge block 4 close to the screening box 3, a drain pipe 5 is penetrated and connected to the lower end of the hole of the screening box 3, sliding rods 502 are slidably connected to both sides of the inner wall of the drain pipe 5, and a buoy 501 and a sealing plate 502 are slidably connected to the upper and lower ends of the sliding rod 502 respectively; Wherein: the sponge block 4 is arranged in an arc shape, the sponge block 4 and the steel wire are horizontally slidably fitted, and the sponge block 4 is connected to the inside of the screening box 3 through the pipe 401; Pipe 401, the pipe 401 extends to the inside of the screening box 3, and the pipe 401 is located in the middle of both sides of the screening box 3; Drain pipe 5, the drain pipe 5 extends to the lower end of the inside of the screening box 3, the drain pipe 5 is arranged vertically, and slide grooves are opened on both sides of the inner wall of the drain pipe 5, and the sliding rod 502 slides in the vertical direction inside the slide groove; Slide grooves are provided on both sides of the inner wall of the drain pipe 5, and the sliding rod 502 slides vertically inside the slide grooves.

The buoy 501 and the sealing plate 503 are both located at the upper and lower ends of the middle of the sliding rod 502. For specific shapes, please refer to the attached manual. Figure 8 As shown; By setting the sliding rod 502, the floating direction of the sealing plate 502 and the buoy 501 can be limited, so as to avoid the sealing plate 502 from tilting as a whole when floating upward, thereby avoiding the sealing plate 502 from being unable to seal the inside of the drain pipe 5; The buoy 501 and the sealing plate 502 are slidably nested with the drain pipe 5 in a vertical direction.

Since the drain pipe 5 is at the lower end of the screening box 3, the clean water enters the interior of the drain pipe 5, and the clean water impacts the upper end of the sealing plate 503. The sealing plate 503 moves downward through the sliding rod 502. At this time, the clean water can flow back to the interior of the screening box 3 through the drain pipe 5, so that this screening feeding equipment can be recycled during the screening process of impurities.

As the wire coil outside the rack 102 gradually decreases and the rack 102 rotates to generate centrifugal force, the telescopic rod 201 slides toward one side of the gasket 202 using the centrifugal force, and the gasket 202 can slide toward one side of the wire coil; S3: The frame 1 conveys the steel wire to one end of the cutting device, and the cutting device can cut the steel wire into abrasive pellets, and the steel wire passes through the internal holes of the screening box 3; S4: by injecting clean water into the water tank 301, the clean water enters the interior of the screening box 3 through the drainage port at the lower end of the water tank 301, and the clean water enters the lower end of the interior of the screening box 3; S5: clean water enters the interior of the screening box 3. When the clean water flows to the lower end of the interior of the screening box 3, the sealing plate 502 floats upward through the buoy 501 by utilizing the buoyancy of the clean water. At this time, the sealing plate 502 can slide into the interior of the drain pipe 5; S6: When the steel wire passes through the side wall of the sponge block 4, the sponge block 4 can screen the impurities and dust on the surface of the steel wire. As the water level inside the screening box 3 rises, clean water can enter the interior of the sponge block 4 through the pipe 401, and the clean water can wash the dust on the surface of the sponge block 4. After washing, the clean water falls to the lower end of the hole of the screening box 3; S7: Since the drain pipe 5 is at the lower end of the screening box 3, clean water enters the drain pipe 5, hits the upper end of the sealing plate 503, and the sealing plate 503 moves downward through the sliding rod 502. At this time, the clean water can flow back to the inside of the screening box 3 through the drain pipe 5.
