It includes a housing, with a cleaning motor fixedly connected to the top of the housing. Multiple push plates are fixedly connected to the output shaft of the cleaning motor. A cleaning cylinder is fixedly connected inside a ring-shaped bracket. A return pipe is fixedly connected between the two sides of the cleaning cylinder, passing through both sides of the cleaning cylinder. A return pump is fixedly connected to the return pipe and is fixedly connected to one side of the cleaning cylinder. By setting up the cleaning cylinder, hollow material blocking plates, cleaning motor, and push plates, the cleaning motor can be started, driving multiple push plates to rotate slowly.

Description

Technical Field

[0001] This utility model belongs to the field of nut production technology, specifically relating to a feeding device for nut production. Background Technology

[0002] A nut is a fastener used for mechanical connections, typically used in conjunction with bolts or threads. It has a central hole with threads inside, primarily used to fasten two or more parts together. Depending on the material, nuts can be classified as carbon steel, stainless steel, and non-ferrous metals. During the manufacturing process, nuts often contain iron filings, which can cause wear during mating, thus reducing their lifespan.

[0003] According to the feeding device for nut production equipment with application number CN202321057101.3, although this patented technology features a motor that drives a drive disc to rotate, which in turn drives a drive rod to move. The drive rod then lifts and presses a connecting rod, which is vertically guided by a guide block and guide hole. A sliding connection exists between the sliding column and the screen, enabling the motor to rapidly rotate and drive the screen to reciprocate. When nuts are being fed, they enter the screen inside the feeding bin from the feeding hopper. The rapid lifting and lowering of the screen causes the nuts, which contain iron slag, to vibrate and shake out the iron slag. This technology separates iron slag from nuts, replacing traditional manual screening and reducing labor costs. However, this patented technology has the following drawbacks in actual use: When tapping nuts, tapping oil is used. Due to the presence of this tapping oil, an adsorption force is generated between the nut and the iron filings. This adsorption force makes it difficult for the iron filings to be completely dislodged from the nut by vibration. In addition, when processing nuts in batches, the iron filings dislodged from the upper nuts may not have passed through the screen before being carried into the material box by the lower nuts, resulting in the nuts not being separated from the iron filings. To address this, we have proposed a feeding device for nut production. Utility Model Content

[0006] In a preferred embodiment, electric push rods are fixedly connected to both sides of the box body, the electric push rods penetrate the box body, and a hollow resisting plate is fixedly connected to the output end of the electric push rod. The hollow resisting plate is slidably connected inside the box body and penetrates the box body.

[0007] In a preferred embodiment, a filter plate is fixedly connected to one side of the top of the hollow material barrier plate, a drain pipe is fixedly connected to one side of the hollow material barrier plate, the drain pipe passes through the hollow material barrier plate, and a valve is fixedly connected to the drain pipe.

[0008] In a preferred embodiment, two heating plates are fixedly connected to the inner cavity of the box, a discharge motor is fixedly connected to one side of the box, the output shaft of the discharge motor passes through the box, a screw is fixedly connected to the output shaft of the discharge motor, a discharge plate is threadedly connected to the external thread of the screw, and the discharge plate is slidably connected between the two heating plates.

[0009] In a preferred embodiment, a vibration motor is fixedly connected to the outside of the housing. The output shaft of the vibration motor passes through the housing. A turntable is fixedly connected to the output shaft of the vibration motor. A cylindrical block is fixedly connected to the turntable. A U-shaped connecting rod is movably connected to the outside of the cylindrical block. A second filter plate is fixedly connected to the top of the U-shaped connecting rod. Two limiting rods are fixedly connected to both sides of the bottom of the second filter plate. A sleeve plate is slidably connected to the outside of the limiting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The feeding device for nut production is equipped with a cleaning cylinder, electric push rod, hollow material blocking plate, cleaning motor and push plate. The cleaning motor can be started to drive multiple push plates to rotate slowly. The push plates push the nut to move, cleaning away the tapping oil on the surface of the nut and causing most of the iron filings on the nut surface to fall off the nut. By controlling the valve, the organic solvent and most of the iron filings are discharged through the drain pipe after passing through the No. 1 filter plate. The electric push rod is started to drive the two hollow material blocking plates to slide outward at the same time, and the nut in the cleaning cylinder falls off. This avoids the problem that the presence of tapping oil causes the nut and iron filings to adhere to each other, making it difficult to clean the iron filings on the surface of the nut by vibration.

[0013] 2. The feeding device for nut production is equipped with a vibrating motor, a U-shaped connecting rod, a second filter plate, a discharge motor, and a discharge plate. Starting the vibrating motor rotates its output shaft, driving the turntable and cylindrical block to rotate. The cylindrical block drives the U-shaped connecting rod and the second filter plate to move up and down rapidly, causing the nuts to move up and down and collide with each other. This vibration causes organic solvents and residual iron filings on the nut surface to be dislodged and fall into the collection box through the second filter plate. Then, starting the discharge motor rotates its output shaft, driving the screw to rotate. The screw rotation moves the discharge plate, pushing out the nuts above the second filter plate. This avoids the problem of incomplete iron filings removal caused by iron filings not completely detaching from the nuts during vibration being carried away by the nuts at the bottom.

[0023] Please see Figures 1-6This utility model provides a feeding device for nut production, including a housing 1. To remove tapping oil from the nuts, a feed pipe is fixedly connected to one side of the top of the housing 1, and the feed pipe penetrates the housing 1. A cleaning motor 2 is fixedly connected to the top of the housing 1, and the output shaft of the cleaning motor 2 penetrates the housing 1. Multiple push plates 3 are fixedly connected to the output shaft of the cleaning motor 2. An annular bracket 4 is fixedly connected to the top of the inner cavity of the housing 1. A cleaning cylinder 5 is fixedly connected inside the annular bracket 4. A return pipe 6 is fixedly connected between the two sides of the cleaning cylinder 5, and the return pipe 6 penetrates both sides of the cleaning cylinder 5. A return pump 7 is fixedly connected to the return pipe 6 and is fixedly connected to one side of the cleaning cylinder 5. Electric push rods 8 are fixedly connected to both sides of the housing 1, and the electric push rods 8 penetrate the housing 1. A hollow material blocking plate 9 is fixedly connected to the output end of the electric push rod 8. The hollow material blocking plate 9 is slidably connected inside the housing 1, and penetrates the housing 1. A hollow material blocking plate 9 is fixedly connected to one side of the top of the hollow material blocking plate 9. There is a filter plate 10. A drain pipe is fixedly connected to one side of a hollow material blocking plate 9, and the drain pipe passes through the hollow material blocking plate 9. A valve 11 is fixedly connected to the drain pipe. Nuts are poured into the cleaning cylinder 5 in batches through the feed pipe. Organic solvent is added to the cleaning cylinder 5. The cleaning motor 2 is started, and the output shaft of the cleaning motor 2 rotates, driving multiple push plates 3 to rotate slowly. The push plates 3 push the nuts to move, and at the same time, the nuts move and collide with each other, cleaning away the tapping oil on the surface of the nuts and removing most of the iron filings from the surface of the nuts. By starting the return pump 7, the flow rate of the organic solvent in the cleaning cylinder 5 is increased, improving the cleaning efficiency. After cleaning, by controlling the valve 11, the organic solvent and most of the iron filings pass through the filter plate 10 and are discharged through the drain pipe. The electric push rod 8 is started, and the output end of the electric push rod 8 extends, driving the two hollow material blocking plates 9 to slide outward at the same time. The nuts in the cleaning cylinder 5 fall off, completing the cleaning of the nuts.

[0024] Please see Figure 1 , Figure 3 and Figure 4To dry the nuts and remove residual iron filings from their surface, two heating plates 14 are fixedly connected to the inner cavity of the housing 1. A vibration motor 16 is fixedly connected to the outside of the housing 1. The output shaft of the vibration motor 16 passes through the housing 1. A turntable 17 is fixedly connected to the output shaft of the vibration motor 16. A cylindrical block 18 is fixedly connected to the turntable 17. A U-shaped connecting rod 19 is movably connected to the outside of the cylindrical block 18. A second filter plate 20 is fixedly connected to the top of the U-shaped connecting rod 19. Two limiting rods 21 are fixedly connected to both sides of the bottom of the second filter plate 20. A sleeve plate 22 is slidably connected to the outside of the limiting rod 21. The sleeve plate 22 is fixedly connected to the inner wall of the housing 1. Limiting plates 23 are fixedly connected to the bottom of both sides of the housing 1. A buffer block is fixedly connected to the top of the filter plate 20. When the nut falls above the second filter plate 20, the vibration motor 16 is started, and the output shaft of the vibration motor 16 rotates, driving the turntable 17 and the cylindrical block 18 to rotate. Under the action of the sleeve plate 22 and the limiting rod 21, the cylindrical block 18 drives the loop connecting rod 19 to move up and down, thereby causing the second filter plate 20 to move up and down rapidly. This causes the nut to move up and down, and the nuts collide with each other, causing the organic solvent and residual iron filings on the surface of the nut to be vibrated off the nut surface and fall into the collection box 24 through the second filter plate 20. The collection box 24 can be pulled out for cleaning. The drying of the nut can be accelerated by the heating plate 14, thereby achieving the purpose of drying the nut and removing the residual iron filings on the surface of the nut.

[0025] Please see Figure 1 and Figure 5 To discharge the nut, a discharge motor 12 is fixedly connected to one side of the housing 1. The output shaft of the discharge motor 12 passes through the housing 1, and a screw 13 is fixedly connected to the output shaft of the discharge motor 12. A discharge plate 15 is threadedly connected to the outside of the screw 13. The discharge plate 15 is slidably connected between two heating plates 14.

A pin 27 is movably connected inside the insertion plate 26. A collection box 24 is slidably connected to the bottom of the inner cavity of the housing 1, and a guide plate is fixedly connected to the bottom of the other side of the housing 1. Pull out the pin 27, remove the baffle 25 from the housing 1, start the discharge motor 12, and rotate the output shaft of the discharge motor 12, which drives the screw 13 to rotate. The rotation of the screw 13 causes the discharge plate 15 to move, pushing out the nut above the second filter plate 20, thereby discharging the nut from the housing 1.

[0026] The working principle and usage process of this utility model are as follows: First, nuts are poured into the cleaning cylinder 5 in batches through the feed pipe. Then, organic solvent is added to the cleaning cylinder 5. The cleaning motor 2 is started, causing its output shaft to rotate, which drives multiple push plates 3 to rotate slowly. The push plates 3 push the nuts to move, and at the same time, the nuts move and collide with each other, cleaning away the tapping oil on the surface of the nuts and removing most of the iron filings from the surface of the nuts. By starting the return pump 7, the flow rate of the organic solvent in the cleaning cylinder 5 is increased, improving the cleaning efficiency. After cleaning, the organic solvent and most of the iron filings are discharged through the drain pipe after passing through the first filter plate 10 by controlling the valve 11. The electric push rod 8 is started, causing its output end to extend and drive the two hollow material blocking plates 9 to slide outwards simultaneously. The nuts in the cleaning cylinder 5 fall out, completing the cleaning of the nuts. The nuts fall above the second filter plate 20, and the vibration motor 16 is started. The output shaft of the vibration motor 16 is rotated, driving the turntable 17 and the cylindrical block 18 to rotate. Under the action of the sleeve plate 22 and the limiting rod 21, the cylindrical block 18 drives the loop connecting rod 19 to move up and down, thereby causing the second filter plate 20 to move up and down continuously and rapidly. This causes the nuts to move up and down, and the nuts collide with each other, causing the organic solvent and residual iron filings on the surface of the nuts to be vibrated off the nut surface and fall into the collection box 24 through the second filter plate 20. The collection box 24 can be pulled out for cleaning. The drying of the nuts can be accelerated by the heating plate 14, thereby achieving the purpose of drying the nuts and removing the residual iron filings on the surface of the nuts. Pull out the pin 27, remove the baffle 25 from the box 1, start the discharge motor 12, and make the output shaft of the discharge motor 12 rotate, driving the screw 13 to rotate. The rotation of the screw 13 causes the discharge plate 15 to move, pushing out the nuts above the second filter plate 20, thereby discharging the nuts out of the box 1.
