Description

Technical Field

[0001] This invention relates to the field of nut technology, specifically to a corrosion-resistant nut production and processing apparatus and method. Background Technology

[0003] Nuts are used in conjunction with screws, bolts, and bolts to fasten and connect components. They are widely used in the automotive, machinery manufacturing, energy, and aerospace industries. Based on their material, nuts can be categorized into several main types, including carbon steel, stainless steel, and non-ferrous metals (copper).

[0004] Currently, due to the harsh operating environment of nuts, corrosion is a common occurrence. Therefore, surface treatments such as galvanizing and chrome plating to improve their corrosion resistance are particularly important. In existing technologies, to ensure the effectiveness of surface treatment, the nut surface typically needs to be cleaned and dried before treatment. However, the following problems exist in this process: 1. Existing cleaning equipment typically uses vigorous agitation to clean the surface of nuts. While this method effectively removes surface dirt and impurities, it also causes violent collisions between the nuts. These collisions not only damage the nut surface and increase the scrap rate, but also raise production costs and affect product quality and reliability.

[0005] 2. Existing drying equipment mainly accelerates the evaporation of cleaning solution by increasing the internal temperature. While this method can achieve a basic drying effect, the drying speed is slow, and it requires stirring to ensure uniform evaporation of the cleaning solution. This makes the drying process complex and time-consuming, and can also cause damage to the surface of the nuts, making it difficult to meet the high-efficiency requirements of modern industrial production.

[0016] Preferably, the cleaning frame is fixedly connected to the rotating shaft, and the rotating shaft can drive the cleaning frame to reciprocate and flip repeatedly.

[0017] A method for manufacturing corrosion-resistant nuts, using the aforementioned corrosion-resistant nut manufacturing apparatus, specifically includes the following steps: Step S1, Loading: Open the cylinder cover, pull the cleaning frame out of the cleaning cylinder, remove the compaction cap and the compaction plug, put the nut into the cleaning frame, put the compaction plug and the compaction cap back into the cleaning frame and press them onto the nut, push the cleaning frame into the cleaning cylinder, use the inner wall of the cleaning cylinder to push the compaction cap against the compaction spring to move into the cleaning frame, and use the compaction spring to press the compaction plug onto the nut; open the vent and the liquid inlet to fill the cleaning cylinder with cleaning liquid, completing the loading process; Step S2, Cleaning: Drive the cleaning frame to move back and forth in the cleaning cylinder to clean the nuts inside the cleaning frame and complete the cleaning work; Step S3, Drainage Switching: After the cleaning work is completed, first open the liquid inlet and the air inlet to drain the cleaning liquid in the cleaning cylinder, and then close the liquid inlet and the air inlet.

[0018] The use of the corrosion-resistant nut production and processing apparatus of the present invention for nut processing has the following beneficial technical effects: 1. In this invention, by setting a compaction plug, a compaction cap, a compaction spring, and a base plate in the cleaning basket, and using the compaction spring to apply force to the compaction plug and the compaction cap, when cleaning and drying nuts, the nuts placed in the cleaning basket can be compacted by the compaction plug and the base plate. When the cleaning basket moves back and forth to fully mix the nuts and cleaning liquid, the nuts can be prevented from violently colliding with each other, thereby avoiding damage to the nuts and improving the processing quality of the nuts.

[0019] 2. In this invention, by setting multiple spaced protrusions at the bottom of the cleaning cylinder and extending the lower end of the bottom plate to the outside of the cleaning frame, the protrusions and the bottom plate can overcome the compression spring during the horizontal reciprocating movement of the cleaning frame and the nut. This allows the nut inside the cleaning frame to reciprocate vertically under the compaction of the bottom plate and the compression plug. This ensures that the nut and cleaning fluid are mixed more thoroughly while preventing violent collisions between the nuts, thus avoiding nut damage and improving the processing efficiency and quality of the nuts.

[0020] 3. In this invention, by arranging a flushing plate on the side of the cleaning frame that is connected to the high-pressure cleaning fluid and whose flushing holes face the cleaning frame, the high-pressure cleaning fluid can be output to the cleaning frame through the flushing holes during the cleaning operation of the nuts. The nuts inside the cleaning frame are then subjected to high-pressure cleaning through the holes opened on the cleaning frame, thereby achieving the flushing operation of the nut surface and improving the cleaning efficiency and effect of the nuts.

[0021] 4. In this invention, by setting a flushing piston, a first one-way valve, and a second one-way valve, a cleaning chamber and a piston chamber are formed on both sides of the flushing piston, respectively. During drying, the reciprocating movement of the flushing piston in the cleaning cylinder causes the piston chamber to continuously expand and contract. Under the action of the first one-way valve and the second one-way valve, the air in the cleaning chamber can be continuously drawn out into the piston chamber and then squeezed out from the piston chamber to the outside, thereby increasing the vacuum degree in the cleaning chamber, accelerating the vaporization of the cleaning liquid in the cleaning chamber, and improving the drying efficiency of the nut.

Detailed Implementation

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Combination Figures 1 to 6As shown, the anti-corrosion nut production and processing device of this embodiment includes a cleaning cylinder 1, a cylinder cover 2, a cleaning frame 3, a base plate 4, a compaction plug 5, a compaction cap 6, and a compaction spring 7. The cleaning cylinder 1 has a vent 8 at the top and a liquid inlet 9 at the bottom. The cylinder cover 2 is located on one side of the cleaning cylinder 1 and is movably connected to it, allowing the cleaning cylinder 1 to be opened and closed. The cleaning frame 3 can be pulled out and pushed into the cleaning cylinder 1. The base plate 4 is slidably disposed within the cleaning frame 3, with its lower end located at the lower end of the cleaning frame 3. The upper end of the base plate 4 extends through the cleaning frame 3 to its upper end and passes through the compaction plug 5, which is slidably disposed at the upper end of the cleaning frame 3. The compaction cap 6 is slidably disposed on the compaction plug 5. The compaction spring 7 is sleeved on the upper end of the base plate 4, with its lower end abutting against the compaction plug 5 and its upper end abutting against the compaction cap 6. The compaction spring 7 can push the compaction cap 6 to move relative to the compaction plug 5 and extend out of the cleaning frame 3, and push the compaction plug 5 to move towards the lower end of the bottom plate 4. The inner wall of the cleaning cylinder 1 can push the compaction cap 6 to move into the cleaning frame 1 against the compaction spring 7.

[0026] In the anti-corrosion nut production and processing device of this embodiment, by setting a compaction plug, a compaction cap, a compaction spring and a base plate in the cleaning frame, the compaction spring applies an action to the compaction plug and the compaction cap. In this way, when cleaning and drying the nuts, the compaction plug and the base plate can compact the nuts in the cleaning basket. When the cleaning basket moves back and forth to make the nuts and cleaning liquid fully mixed, the nuts can avoid violent collisions, thereby avoiding damage to the nuts and improving the processing quality of the nuts.

[0027] Combination Figure 1 As shown, in the anti-corrosion nut production and processing device of this embodiment, a limiting pin 10 and a limiting groove 11 are provided between the compaction plug 5 and the compaction cap 6, thereby limiting the relative movement distance and position between the compaction plug 5 and the compaction cap 6, thereby forming a small component of the compaction plug 5, the compaction cap 6 and the compaction spring 7, so as to facilitate the disassembly and assembly of the compaction plug and improve the convenience and efficiency of operation.

[0028] Combination Figure 1 As shown, in the anti-corrosion nut production and processing apparatus of this embodiment, the cleaning cylinder 1 has multiple protrusions 12 spaced apart inside, and the lower end of the base plate 4 extends out of the cleaning frame 3. At this time, when the cleaning frame 3, carrying the base plate 4, reciprocates within the cleaning cylinder 1, that is, along... Figure 1 When the horizontal reciprocating motion is shown, the base plate 4 can abut against the boss 12 and move relative to the cleaning frame 3, that is, it performs... Figure 1 The vertical reciprocating movement shown enables the nut to reciprocate both horizontally and vertically within the cleaning cylinder.

[0029] In the anti-corrosion nut production and processing apparatus of this embodiment, by providing multiple spaced protrusions at the bottom of the cleaning cylinder and extending the lower end of the base plate outside the cleaning frame, the nuts can be moved within the cleaning frame. Figure 1 During the horizontal reciprocating movement shown, the boss and the base plate abut against each other to overcome the compression spring, causing the nut inside the cleaning frame to move under the compaction action of the base plate and the compression plug. Figure 1 The vertical reciprocating movement shown in the figure ensures that the nuts and cleaning fluid are mixed more thoroughly while preventing violent collisions between the nuts, thus avoiding nut damage and improving the processing efficiency and quality of the nuts.

[0030] Combination Figure 1 and Figure 3 As shown, the anti-corrosion nut production and processing device in this embodiment is also provided with a rinsing plate 13. The rinsing plate 13 is provided with a plate rinsing hole 14. The rinsing plate 13 is located on one side of the cleaning frame 3. The plate rinsing hole 14 is connected to the high-pressure cleaning fluid and faces the cleaning frame 3.

[0031] At this point, by arranging a flushing plate on the side of the cleaning frame that is connected to the high-pressure cleaning fluid and whose flushing holes face the cleaning frame, the high-pressure cleaning fluid can be output to the cleaning frame through the flushing holes during the cleaning operation of the nuts. Then, the nuts inside the cleaning frame can be cleaned under high pressure through the holes opened on the cleaning frame, thereby achieving the flushing operation of the nut surface and improving the cleaning efficiency and effect of the nuts.

[0032] Combination Figure 3 As shown, in the anti-corrosion nut production and processing device of this embodiment, the flushing plate 13 is also provided with a flushing channel 15. One end of the flushing channel 15 is connected to the plate flushing hole 14, and the other end is provided with a flushing solenoid valve 16, which is connected to an external injection pump. At this time, by controlling the opening and closing of the flushing solenoid valve, the injection pump can be controlled to introduce high-pressure cleaning fluid into the flushing channel, and then output to the cleaning frame through the plate flushing hole, thereby realizing the high-pressure flushing operation of the nuts in the cleaning frame.

[0033] Combination Figure 1 As shown, the anti-corrosion nut production and processing apparatus of this embodiment is also equipped with an ultrasonic generator 17. The ultrasonic generator 17 is disposed at the bottom of the cleaning cylinder 1 and is used to perform ultrasonic cleaning on the nuts in the cleaning cylinder 1.

[0034] In the anti-corrosion nut production and processing device of this embodiment, an ultrasonic generator can be set up to perform ultrasonic cleaning on the nut. After the ultrasonic cleaning shakes off the impurities on the surface of the nut, the high-pressure cleaning fluid flowing out of the rinsing plate can wash the impurities away from the nut. At the same time, with the reciprocating movement of the cleaning basket, the nut can be better rinsed, thereby obtaining a better cleaning effect.

[0035] Combination Figure 2 As shown, the anti-corrosion nut production and processing apparatus of this embodiment is also equipped with a heating wire 18. The heating wire 18 is installed on the cleaning cylinder 1 and is used to heat the air inside the cleaning cylinder 1. At this time, after the cleaning operation of the nuts inside the cleaning cylinder is completed, the cleaning liquid inside the cleaning cylinder is discharged and air is introduced through the air inlet and liquid inlet. Then, the heating wire can be used to heat the air inside the cleaning cylinder to achieve the drying operation of the nuts inside the cleaning cylinder.

[0036] Combination Figure 1 and Figure 6 As shown, the anti-corrosion nut production and processing apparatus of this embodiment also includes a flushing piston 19, a first one-way valve 20, and a second one-way valve 21. The flushing piston 19 is slidably disposed within the cleaning cylinder 1, dividing the interior of the cleaning cylinder 1 into a cleaning chamber 22 and a piston chamber 23. The first one-way valve 20 is disposed between the piston chamber 23 and the cleaning chamber 22 to unidirectionally introduce gas from the cleaning chamber 22 into the piston chamber 23. The second one-way valve 21 is disposed between the piston chamber 23 and the outside atmosphere to unidirectionally lead gas from the piston chamber 23 out to the atmosphere.

[0037] In the anti-corrosion nut production and processing device of this embodiment, by setting a flushing piston, a first one-way valve and a second one-way valve, a cleaning chamber and a piston chamber are formed on both sides of the flushing piston, respectively. During drying, the reciprocating movement of the flushing piston in the cleaning cylinder causes the piston chamber to continuously expand and contract. Under the action of the first one-way valve and the second one-way valve, the air in the cleaning chamber can be continuously drawn out into the piston chamber and then squeezed out from the piston chamber to the outside, thereby increasing the vacuum degree in the cleaning chamber, accelerating the vaporization of the cleaning liquid in the cleaning chamber, and improving the drying efficiency of the nuts.

[0038] Combination Figure 1 , Figure 4 and Figure 6 As shown, the anti-corrosion nut production and processing device in this embodiment also includes a motor 24, a first connecting rod 25, a second connecting rod 26, a sliding plate 27, and a control shaft 28. The motor 24 is mounted on the cylinder cover 2. One end of the first connecting rod 25 is connected to the output end of the motor 24, and the other end of the first connecting rod 25 is connected to one end of the second connecting rod 26. The other end of the second connecting rod 26 is connected to the sliding plate 27, which is sleeved on the control shaft 28. The control shaft 28 passes through the cylinder cover 2 and the piston chamber 23 and connects to the flushing piston 19.

[0039] At this point, the motor, the first connecting rod, the second connecting rod, and the sliding plate can be used to drive the control shaft to reciprocate relative to the cylinder cover, thereby driving the flushing piston to reciprocate and achieve the vacuuming operation of the cleaning chamber.

[0040] Combination Figure 1and Figure 6 As shown, the anti-corrosion nut production and processing device in this embodiment also includes a rotating shaft 29, an inner shaft 30, a first steel ball 31, and a second steel ball 32. One end of the rotating shaft 29 is connected to the cleaning frame 3, and the other end passes through the cylinder cover 2. A sliding plate 27 is connected to the rotating shaft 29, and the sliding plate 27 can move synchronously axially and rotate relative to the rotating shaft 29 in a circumferential direction. Figure 1 The system exhibits synchronous horizontal movement and relative circumferential rotation. The inner shaft 30 is coaxially slidably disposed inside the control shaft 28. The control shaft 28 has an airflow channel 33 communicating with the piston chamber 23. A first one-way valve 20 is disposed at the end of the inner shaft 30. The first steel ball 31 and the second steel ball 32 are both disposed on the control shaft 28. The cylinder cover 2 has a cylinder cover groove 34, the sliding plate 27 has a sliding plate groove 35, and the inner shaft 30 has an annular groove 36.

[0041] The inner shaft 30 can move relative to the control shaft 28 to connect with the outlet of the first one-way valve 20 and the air flow channel 33, the first steel ball 31 can disengage from the cylinder cover groove 34 and move to the annular groove 36, and the second steel ball 32 can disengage from the annular groove 36 and move to the slide plate groove 35. The inner shaft 30 can also move relative to the control shaft 28 to disconnect the outlet of the first one-way valve 20 from the air flow channel 33, the first steel ball 31 can disengage from the annular groove 36 and move to the cylinder cover groove 34, and the second steel ball 32 can disengage from the slide plate groove 35 and move to the annular groove 36. Figure 6 The position and state shown.

[0042] In the anti-corrosion nut production and processing device of this embodiment, by setting a rotating shaft and an inner shaft, as well as a first steel ball, a second steel ball, a cylinder cover groove, a slide plate groove, and an annular groove, the rotating shaft can be moved back and forth by the sliding plate, while the position of the inner shaft relative to the control shaft is moved. This changes the connection relationship between the control shaft and the sliding plate and the cylinder cover. That is, the control shaft is connected to the sliding plate to drive the flushing piston to move back and forth, or the control shaft is connected to the cylinder cover to keep the flushing piston in a fixed position, thereby realizing different operations of the cleaning and drying processes.

[0043] Combination Figure 1 and Figure 6 As shown, the anti-corrosion nut production and processing device in this embodiment is further provided with a switching push rod 37. The switching push rod 37 is disposed at the end of the control shaft 28 and connected to the inner shaft 30 to drive the inner shaft 30 to reciprocate relative to the control shaft 28, thereby adjusting and changing the position of the first steel ball 31 and the second steel ball 32.

[0044] Meanwhile, in this embodiment, the holes for the first steel ball 31 and the second steel ball 32 on the control shaft 28 are designed with inward openings. This ensures that the first steel ball 31 and the second steel ball 32 are always connected to the control shaft 28 and will not detach from the control shaft 28, thereby improving the reliability and stability of operation.

[0045] Furthermore, in the anti-corrosion nut production and processing device of this embodiment, the cleaning frame 3 and the rotating shaft 29 are fixedly connected. In this way, the rotating shaft 29 can not only drive the cleaning frame 3 to move back and forth, but also pull the cleaning frame 3 out of the cleaning cylinder 1 using the rotating shaft 29, and then flip the cleaning frame 3 to pour out the nuts in the cleaning frame 3, thus completing the rapid unloading operation of the nuts.

[0046] Combination Figure 1 As shown, in the anti-corrosion nut production and processing device of this embodiment, two rinsing plates 13 are provided, and the two rinsing plates 13 are also fixedly connected to the rotating shaft 29 to ensure that the rinsing plates 13 can move synchronously with the cleaning frame 3 to effectively rinse the nuts in the cleaning frame 3.

[0047] At the same time, combined Figure 1 and Figure 3 As shown, in this embodiment, the flushing piston 19 is disposed at... Figure 1 On one side of the rightmost cleaning frame 3 shown, there is also a piston flushing hole 41 and a flushing channel 15, which are fixedly connected to the flushing plate 13 to flush the high-pressure cleaning fluid to the left cleaning frame 3. That is, the flushing piston 19 also plays the role of the flushing plate 13 to flush the nut under high pressure. However, the flushing piston 19 and the rotating shaft 29 are slidably connected, so that the flushing piston 19 can reciprocate with the control shaft 28.

[0048] In addition, combined Figure 1 As shown, the anti-corrosion nut production and processing device in this embodiment is also provided with a switch push rod 38. The switch push rod 38 is disposed on the cleaning cylinder 1, and the extended end of the switch push rod 38 is connected to the cylinder cover 2, so as to drive the cylinder cover 2 to reciprocate relative to the cleaning cylinder 1, thereby realizing the opening and closing of the cleaning cylinder 1, and realizing the operation of pulling out or pushing the cleaning frame 3 into the cleaning cylinder 1 through the sliding plate 27 and the rotating shaft 29.

[0049] In addition, combined Figure 1 As shown, in the anti-corrosion nut production and processing device of this embodiment, there is also a venting solenoid valve 39 located at the vent 8 and a liquid solenoid valve 40 located at the liquid inlet 9. The venting solenoid valve 39 can control the opening and closing of the vent 8 with the outside atmosphere, and the liquid solenoid valve 40 can control the opening and closing of the liquid inlet 9 with the injection pump and the drainage pump respectively, so as to realize the liquid injection and drainage operations in the cleaning cylinder 1.

[0050] Combination Figures 1 to 6 As shown, the specific steps for processing nuts using the aforementioned anti-corrosion nut production and processing device include: Step S1, Loading: Open the cylinder cover, pull the cleaning frame out of the cleaning cylinder, take out the compaction cap and compaction plug, put an appropriate amount of nut into the cleaning frame, put the compaction plug and compaction cap back into the cleaning frame and press them on the nut, push the cleaning frame into the cleaning cylinder, use the inner wall of the cleaning cylinder to push the compaction cap to move into the cleaning frame against the compaction spring, and press the compaction plug on the nut through the compaction spring; open the vent and liquid inlet, and fill the cleaning liquid into the cleaning cylinder to complete the loading work.

[0051] Specifically, the control switch push rod 38 extends, pushing the cylinder cover 2 to... Figure 1 The movement to the right, as shown, is achieved by the motor 24, first connecting rod 25, second connecting rod 26, and sliding plate 27 located on the cylinder cover 2, which synchronously move the rotating shaft 29 to the right to pull the cleaning frame 3 out of the cleaning cylinder 1. At this time, the inner shaft 30 is located at... Figure 6 The first steel ball 31 is positioned in the cylinder cover groove 34 and the second steel ball 32 is positioned in the annular groove 36, so that the control shaft 28 remains connected to the cylinder cover 2, thereby driving the flushing piston 19 to move out of the cleaning cylinder 1 synchronously. After the cleaning frame 3 is pulled out of the cleaning cylinder 1, the compaction plug 5 is removed from the cleaning frame 3, the nut is placed into the cleaning frame 3, and then the compaction plug 5 is put back into the cleaning frame 3 and pressed onto the nut. Afterwards, the control switch push rod 38 retracts, driving the cylinder cover 2 and the rotating shaft 29 to move towards the cylinder cover 2. Figure 1 The leftward movement moves the cleaning frame 3 and the flushing piston 19 into the cleaning cylinder 1. When the cleaning frame 3 enters the cleaning cylinder 1, the inner wall of the cleaning cylinder 1 abuts against the top of the compaction cap 6, and the compaction spring 7 applies downward force to the compaction plug 5, causing the nut to be compacted between the compaction plug 5 and the bottom plate 4. After the cylinder cover 2 is replaced on the cleaning cylinder 1, the venting solenoid valve 39 is opened to connect the vent 8 to the outside atmosphere, and the liquid-injecting solenoid valve 40 is opened to connect the liquid injection pump to the liquid-injecting port 9. Cleaning liquid is injected into the cleaning cylinder 1 through the liquid injection pump and the liquid-injecting port 9, while air is discharged through the vent 8. After the appropriate amount of cleaning liquid has been injected, the liquid-injecting solenoid valve 40 is closed to complete the loading process.

[0052] Step S2, Cleaning: Drive the cleaning frame to move back and forth in the cleaning cylinder to clean the nuts inside the cleaning frame, thus completing the cleaning work.

[0053] Specifically, after completing the feeding operation in step S1, firstly, the motor 24 is started, which drives the sliding plate 27 through the first connecting rod 25 and the second connecting rod 26. Figure 1 The horizontal reciprocating movement is shown, at which point the inner shaft 30 is located... Figure 6The positions shown are such that the first steel ball 31 is located in the cylinder cover groove 34 and the second steel ball 32 is located in the annular groove 36. The control shaft 28 remains connected to the cylinder cover 2, and the sliding plate 27 slides relative to the control shaft 28, thereby driving the rotating shaft 29 to rotate. Figure 1 The horizontal reciprocating movement shown in the diagram causes the cleaning frame 3 to move horizontally within the cleaning cylinder 1, resulting in the compacted nut reciprocating horizontally in the cleaning fluid. When the base plate 4 moves to contact the boss 12, the boss 12 pushes the base plate 4 upward. The base plate 4 then pushes the compaction plug 5 upward through the compacted nut, overcoming the force of the compaction spring 7. This causes the compacted nut to simultaneously reciprocate up and down in the cleaning fluid, ensuring thorough mixing between the nut and the cleaning fluid. Then, the flushing solenoid valve 16 is opened, and high-pressure cleaning fluid is injected into the flushing channel 15 via an external pump. The high-pressure cleaning fluid then flows through the flushing holes 14 on the flushing plate 13 and the piston flushing holes 41 on the flushing piston 19 onto the nut inside the cleaning frame 3. Simultaneously, the ultrasonic generator 17 is activated to ultrasonically clean the nut in the cleaning fluid, dislodging impurities from the nut surface. These impurities are then further removed by the high-pressure flushing fluid, resulting in a thorough cleaning of the nut. During the cleaning process, the opening and closing of the liquid-passing solenoid valve 40 can be controlled intermittently to create an intermittent connection between the liquid discharge pump and the liquid inlet 9. The liquid discharge pump is used to discharge part of the cleaning liquid in the cleaning cylinder 1. The discharged cleaning liquid is then treated by filtering impurities and then recycled. After the surface of the nut is cleaned, the cleaning work is completed.

[0054] Step S3, Drainage Switching: After completing the cleaning work, first open the liquid inlet and the air inlet to drain the cleaning liquid in the cleaning cylinder, and then close the liquid inlet and the air inlet.

[0055] Specifically, after completing the cleaning operation in step S2, the flushing solenoid valve 16 is closed to stop the injection of high-pressure cleaning fluid; the motor 24 is stopped rotating, and the cleaning frame 3 is stopped moving. Figure 1 As shown in the diagram; control the liquid-flow solenoid valve 40 to open, connecting the drain pump to the liquid inlet 9, and draining the cleaning liquid from the cleaning cylinder 1; control the vent solenoid valve 39 to open, allowing outside air to enter the cleaning cylinder 1 through the vent 8, draining the cleaning liquid from the cleaning cylinder 1, and then control the vent solenoid valve 39 and the liquid-flow solenoid valve 40 to close. Control the switching push rod 37 to extend, pushing the inner shaft 30 relative to the control shaft 28. Figure 6The movement to the left causes the first steel ball 31 to exit the cylinder cover groove 34 and enter the annular groove 36, and the second steel ball 32 to exit the annular groove 36 and enter the sliding plate groove 35. This causes the control shaft 28 to disengage from the cylinder cover 2 and switch to a fixed connection with the inner shaft 30, while the sliding plate 27 switches to a fixed connection with the control shaft 28. Thus, the sliding plate 27 can drive the control shaft 28, the inner shaft 30, and the rotating shaft 29 relative to the cleaning cylinder 1 and the cylinder cover 2. Figure 1 The horizontal reciprocating movement shown in the figure, at the same time, the movement of the inner shaft 30 relative to the control shaft 28 connects the outlet of the first one-way valve 20 with the piston chamber 23, thus completing the liquid discharge switching operation.

[0056] Step S4, Drying: After draining the cleaning liquid from the cleaning drum, heat the air inside the cleaning drum to dry the nuts in the cleaning frame.

[0057] Specifically, after completing the switching operation in step S3, the heating wire 18 is activated to heat the air inside the cleaning cylinder 1, and the motor 24 is started, driving the sliding plate 27 through the first connecting rod 25 and the second connecting rod 26. Figure 1 The horizontal reciprocating movement shown in the figure causes the sliding plate 27 to drive the control shaft 28, inner shaft 30, and rotating shaft 29 to reciprocate synchronously, thereby causing the cleaning frame 3 and the rinsing piston 19 to reciprocate horizontally within the cleaning cylinder 1. At this time, through the cooperation of the bottom plate 4 and the boss 12, the cleaning frame 3, carrying the nut, reciprocates in both the horizontal and vertical directions, causing the residual cleaning liquid on the surface of the nut to be thrown off. Simultaneously, the reciprocating movement of the rinsing piston 19 compresses the piston chamber 23, causing the air in the cleaning cylinder 1 to continuously enter the piston chamber 23 through the first one-way valve 20 and then be continuously discharged through the second one-way valve 21. This gradually reduces the air pressure in the cleaning chamber 22, increases the vacuum degree of the cleaning chamber 22, accelerates the vaporization of the cleaning liquid, and completes the drying operation.

[0058] Step S5, unloading and equipment reset: After the drying process is completed, open the cylinder cover again, pull the cleaning frame out of the cleaning cylinder, take out the compaction cap and compaction plug, remove the nut in the cleaning frame to complete the unloading, then put the compaction cap and compaction plug into the cleaning frame, push the cleaning frame into the cleaning cylinder to complete the equipment reset.

[0059] Specifically, after completing the drying operation in step S4, the ventilation solenoid valve 39 is opened, allowing outside air to enter the cleaning cylinder 1 through the ventilation port 8. The control motor 24 stops operating, and the control shaft 28 is moved until the first steel ball 31 is aligned with the cylinder cover groove 34. The control switching push rod 37 is then retracted, pulling the inner shaft 30 relative to the control shaft 28. Figure 6The movement to the right causes the first steel ball 31 to exit the annular groove 36 and enter the cylinder cover groove 34, and the second steel ball 32 to exit the sliding plate groove 35 and enter the annular groove 36. This re-establishes a fixed connection between the control shaft 28 and the cylinder cover 2, while the sliding plate 27 switches off its fixed connection with the control shaft 28. Thus, the sliding plate 27 can drive the rotating shaft 29 to... Figure 1 The horizontal reciprocating movement shown indicates that the control shaft 28 can move along with the cylinder cover 2. Figure 1 The cylinder moves back and forth in the horizontal direction as shown. Then, the control switch push rod 38 extends, pushing the cylinder cover 2 towards... Figure 1 Moving to the right as shown, the cleaning frame 3 and the flushing piston 19 are pushed out of the cleaning cylinder 1 again. After all the cleaning frames 3 are completely pushed out of the cleaning cylinder 1, the rotating shaft 29 is controlled to rotate, and the compaction cap 6, compaction plug 5 and nut are poured out of the cleaning frame 3. The nuts are collected manually to complete the unloading operation. Then the rotating shaft 29 is rotated in the opposite direction, and the compaction cap 6 and compaction plug 5 are put back into the cleaning frame 3. The control switch push rod 38 is retracted to bring the cleaning frame 3 back into the cleaning cylinder 1, completing the equipment reset and the unloading and equipment reset operations.
