Description

Technical Field

[0001] This utility model relates to the field of screw manufacturing technology, and in particular to a cleaning device for screw manufacturing. Background Technology

[0002] Screw cleaning devices are mainly used to rinse and filter contaminants generated or introduced into screws during manufacturing, assembly, use and maintenance, so as to improve the cleanliness of screws, avoid or reduce failures caused by contamination, and thus ensure the high performance, high reliability and long service life of screws and the equipment they are in.

[0003] For example, Chinese utility model patent (CN221361580U) discloses a screw surface oil stain cleaning device, which solves the problem that although the existing technology can clean screws, the cleaning is relatively slow. By adding water and cleaning solution into the cleaning cylinder, the height adjustment structure drives the stroke plate to move downward. The stroke plate drives the rotating structure and electromagnetic adsorption component to extend into the cavity of the cleaning cylinder. The electromagnetic adsorption component adsorbs the screw, and then the rotating structure drives the magnetically adsorbed screw to rotate, so that the screw can better contact the water and cleaning solution, thereby achieving the cleaning and removal of oil stains from the screw.

[0004] While the aforementioned screw surface oil cleaning device can attract screws using an electromagnetic adsorption component, thus solving the problem of screws being thrown out of the cleaning cylinder during the high-speed rotation of the stirring blades, in actual operation, we found that the adsorption surface between the screw and the electromagnetic adsorption component remains in contact with the screw. During the screw-swinging cleaning process, the cleaning fluid cannot penetrate into the adsorption surface between the screw and the electromagnetic adsorption component to clean it. This results in incomplete cleaning of the screw surface, leaving some oil residue on the screw surface after cleaning, leading to poor screw cleaning performance.

[0005] Furthermore, if the aforementioned screw surface oil stain cleaning device is to thoroughly clean the screws, the electromagnetic adsorption component must be de-energized, the screws that have been cleaned once must be put down again, and then the electromagnetic adsorption component must be restarted to adsorb the screws a second time and clean them again in order to completely remove the oil stains attached to the screw surface. If this method is used, the efficiency of screw cleaning will be reduced. Moreover, when adsorbing the screws a second time, the electromagnetic adsorption component may still adsorb the side of the screw with oil stains, resulting in some screws that have not been thoroughly cleaned after the second cleaning. The practical performance of the device is poor.

[0006] On the other hand, most existing screw cleaning devices can only clean one type of screw at a time. However, smaller factories, due to their smaller production scale, typically don't have a large stock of screws requiring cleaning. Cleaning only one type of screw at a time often results in insufficient screw capacity within the cleaning device, hindering its full utilization. To maximize the internal space, multiple sizes of screws need to be cleaned simultaneously. However, while this method utilizes the internal space effectively, it doesn't allow for proper sorting and collection of the cleaned screws, leading to a pile-up of screws of various sizes after cleaning, resulting in poor actual performance of the device.

[0007] To address this issue, we have designed a cleaning device for screw production, providing an alternative technical solution to the aforementioned technical problems. Utility Model Content

[0018] 1. This utility model provides a cleaning device for screw production. Through the design of the cleaning components, the operator only needs to put the screws to be cleaned into the inner cylinder, and then let water flow into the inner cylinder through the water inlet. An appropriate amount of cleaning solution is squeezed into the inner cylinder. Then, the drive motor is started to control the inner cylinder to rotate, so that the water mixed with the cleaning solution rinses the screws. During the rinsing process, the centrifugal force generated by the rotation of the inner cylinder causes the screws to move towards the inner wall of the inner cylinder and collide with multiple cleaning brushes set on the inner wall, thereby improving the cleaning effect of the screws and achieving all-round cleaning of the screws.

[0019] 2. The screw cleaning device provided by this utility model, through the design of the flipping component, allows the operator to simply drain the cleaning waste liquid inside the inner cylinder after the screws are cleaned, and then start the second drive motor to drive the cleaning cylinder to rotate counterclockwise along the main body of the cleaning device. During the rotation of the cleaning cylinder, the cylinder cover connected by the hinge at the top of the cleaning cylinder will open continuously, thereby pouring out the cleaned screws inside the cleaning cylinder. After the cleaning cylinder has rotated 180 degrees, the second drive motor stops for a period of time to keep the cylinder cover fully open, thereby pouring out all the cleaned screws inside the cleaning cylinder. Then, the second drive motor is restarted to drive the cleaning cylinder to continue to rotate counterclockwise 180 degrees to reset, thus completing the unified dumping of the cleaned screws.

[0020] 3. The screw production cleaning device provided by this utility model, through the design of the positioning and abutment component, ensures the normal connection between the multiple water inlet pipes and drain pipes on the outside of the cleaning cylinder and the external water inlet system and drainage system without affecting the normal operation of the flipping component, thus effectively ensuring the normal use of the screw production cleaning device.

[0021] 4.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] Example

[0033] Reference Figure 1-7A cleaning device for screw production includes a main body 1. A cleaning cylinder 2 for cleaning screws is rotatably mounted inside the main body 1. The top and bottom of the cleaning cylinder 2 have multiple water inlets 3 and drain outlets 4. The cleaning cylinder 2 includes an inner cylinder 5, an outer cylinder 6, and a cover 7. The inner cylinder 5 is rotatably mounted inside the outer cylinder 6. The cover 7 is hinged to the top of the outer cylinder 6. A cleaning assembly for cleaning screws is located inside the cleaning cylinder 2. A tilting assembly for tilting the cleaning cylinder 2 is mounted on the main body 1. Positioning and abutting assemblies that cooperate with the tilting assembly are located at the water inlets 3 and drain outlets 4 of the cleaning cylinder 2. A drying and collecting assembly for drying and collecting the cleaned screws is located at the bottom of the cleaning cylinder 2. The cleaning assembly includes a drive motor 8 located at the bottom of the outer cylinder 6. The output of the drive motor 8... The outer cylinder 6 is connected to a planetary gear set 9, which is fixedly mounted on the outer cylinder 6. The output end of the planetary gear set 9 is fixedly connected to the bottom wall of the inner cylinder 5. Multiple cleaning brushes 10 for scrubbing screws are fixedly mounted on the inner wall of the inner cylinder 5. Specifically, in this utility model, through the design of the cleaning component, the operator only needs to put the screw to be cleaned into the inner cylinder 5, and then let water flow into the inner cylinder 5 through the water inlet 3, and squeeze an appropriate amount of cleaning liquid into the inner cylinder 5. Then, the drive motor 8 is started to control the inner cylinder 5 to rotate, so that the water mixed with the cleaning liquid rinses the screw. During the rinsing process, the centrifugal force generated by the rotation of the inner cylinder 5 causes the screw to move towards the inner wall of the inner cylinder 5 and collide with the multiple cleaning brushes 10 mounted on the inner wall of the inner cylinder 5, thereby improving the cleaning effect of the screw and achieving all-round cleaning of the screw.

[0034] It should be noted that in this utility model, during the cleaning process of the screws, the cleaning liquid and oil stains attached to the screw surface can be removed by multiple drainage and water intake to ensure the cleanliness of the screws after cleaning and improve the practical performance of the device. Through the design of the planetary gear set 9, the output torque of the drive motor 8 is effectively increased, so that the drive motor 8 can drive the inner cylinder 5 filled with cleaning liquid and screws to rotate normally, thereby effectively ensuring the normal operation of the device.

[0035] Reference Figure 2-4The flipping assembly includes a second drive motor 11 located on one side of the main body 1 of the cleaning device. A reducer 12 is fixedly connected to the output end of the second drive motor 11. The main body 1 of the cleaning device is provided with a mounting plate 13 to facilitate the placement of the second drive motor 11 and the reducer 12. The output end of the reducer 12 passes through the main body 1 of the cleaning device and is fixedly connected to the outer wall of the cleaning cylinder 2. Specifically, in this invention, through the design of the flipping assembly, after the screws are cleaned, the operator only needs to drain the cleaning waste liquid inside the inner cylinder 5 before starting the second drive motor 11. 1. Drive the cleaning cylinder 2 to rotate counterclockwise along the main body 1 of the cleaning device. During the rotation of the cleaning cylinder 2, the cylinder cover 7 connected by the hinge at the top of the cleaning cylinder 2 will open continuously, thereby emptying the cleaned screws inside the cleaning cylinder 2. After the cleaning cylinder 2 rotates 180 degrees, the drive motor 11 stops for a period of time, keeping the cylinder cover 7 fully open, thereby emptying all the cleaned screws inside the cleaning cylinder 2. Then, the drive motor 11 is restarted, and the cleaning cylinder 2 continues to rotate counterclockwise 180 degrees to reset, thus completing the unified emptying of the cleaned screws.

[0036] It should be noted that in this utility model, the design of the reducer 12 effectively increases the output torque of the drive motor 11, enabling the drive motor 11 to drive the cleaning cylinder 2 filled with screws to rotate normally, so that the screws can be poured out of the cleaning cylinder 2 normally, effectively ensuring the normal operation of the device.

[0037] Reference Figure 4-5 The inlet 3 and outlet 4 are provided with mounting holes 14 at their upper and lower ends to facilitate the installation of the positioning and abutting assembly. The positioning and abutting assembly includes a connecting sleeve movably disposed inside the inlet 3 and outlet 4. Limiting blocks 16 are fixedly connected to the upper and lower ends of the connecting sleeve. A semi-circular positioning block 17 is fixedly connected to the side of the limiting block 16 near the main body 1 of the cleaning device. The main body 1 of the cleaning device has a positioning hole 18 that matches the semi-circular positioning block 17. The semi-circular positioning block 17 is engaged by the limiting block 16. Inside the mounting hole 14, a compression spring 19 is provided on the side of the limiting block 16 away from the semi-circular positioning block 17. The two ends of the compression spring 19 are fixedly connected to the limiting block 16 and the inner wall of the mounting hole 14, respectively. Specifically, in this utility model, through the design of the positioning and abutment component, the multiple water inlet pipes and drain pipes provided outside the cleaning cylinder 2 are ensured to maintain normal connection between the water inlet pipes and drain pipes and the external water inlet system and drainage system without affecting the normal operation of the flipping component, thus effectively ensuring the normal use of the cleaning device for screw production.

[0038] It should be noted that in this utility model, under the compression of the compression spring 19, the outer end of the semi-circular abutment slightly exceeds the outer end of the connecting sleeve 15. This design allows the connecting sleeve 15 to retract inward when the semi-circular abutment moves out of the positioning hole 18, thereby avoiding unnecessary wear between the connecting sleeve 15 and the main body 1 of the cleaning device during the rotation of the cleaning cylinder 2, and improving the practicality of the device. On the other hand, the inner cylinder 5 is equipped with multiple solenoid valves (not shown in detail in the figure) that close the water inlet 3 and the drain outlet 4. The design of the solenoid valves makes it easy for the staff to uniformly control the opening and closing of multiple water inlets 3 and drain outlets 4, thereby controlling the water inlet and drainage of the inner cylinder 5 and ensuring the normal operation of the cleaning component and the rotation component.

[0039] After the screws are cleaned, the drive motor 8 is stopped. The water inlet 3 and drain outlet 4 on the inner cylinder 5 automatically rotate to their positions aligned with the water inlet 3 and drain outlet 4 on the outer cylinder 6 according to a pre-set program. Then, the solenoid valve at the drain outlet 4 is opened to discharge the cleaning waste liquid inside the inner cylinder 5. Then, the drive motor 11 is started to rotate the cleaning cylinder 2 180 degrees counterclockwise to empty all the cleaned screws from inside the cleaning cylinder 2. Then, the cleaning cylinder 2 continues to rotate 180 degrees counterclockwise to reset it. During this process, the semi-circular positioning block 17, which is movable inside the outer cylinder 6, will retract inward under the pressure of the main body 1 of the cleaning device, thereby... The connecting sleeve 15 is moved towards the center of the outer cylinder 6, causing it to retract into the inlet 3 and outlet 4. As the outer cylinder 6 gradually rotates and resets, the semi-circular positioning block 17 is inserted into the positioning hole 18 under the action of the compression spring 19 during the gradual reset of the outer cylinder 6. At this time, the connecting sleeve 15 is pressed against the inner wall of the main body 1 of the cleaning device under the action of the semi-circular positioning block 17. Then, the operator puts the screw to be cleaned into the inner cylinder 5, adds clean water through the inlet 3 and squeezes in an appropriate amount of cleaning solution, then controls the solenoid valve to close the inlet 3 and outlet 4, and starts the drive motor 8 to drive the inner cylinder 5 to rotate inside the outer cylinder 6 to clean the screw.

[0040] Reference Figure 6-7The drying and collecting assembly includes a vibrating feeding net 20, a vibrating motor 21, and an electric heating module 22. The vibrating feeding net 20 has multiple sections, and mounting side plates 23 are fixedly connected to both sides of each section. A strip-shaped mounting plate 24 is fixedly connected to the top of each mounting side plate 23. The vibrating motor 21 is fixedly mounted on the strip-shaped mounting plate 24. The electric heating module 22 is suspended from the top of the vibrating feeding net 20, and its two ends are fixedly connected to the inner wall of the main body 1 of the cleaning device. Multiple spring supports 25 are fixedly connected to the bottom of each of the two mounting side plates 23. The bottoms of the multiple spring supports 25 are fixedly installed inside the main body 1 of the cleaning device. Each of the multiple vibrating feeding nets 20 has a guide baffle 26 for guiding screws. The bottom of the vibrating feeding net 20 has multiple screw collection boxes 27 for collecting the screws. Specifically, in this utility model, the design of the drying and collecting assembly facilitates the drying and sorting of screws of various specifications, thereby preventing screws of various specifications from piling up after cleaning and improving the actual use effect of the device.

[0041] In actual operation, the screws poured out from the cleaning cylinder 2 fall directly onto the vibrating feeding mesh 20. At this time, the vibrating motor 21 starts, driving the screws to vibrate and transport on the first layer of the vibrating feeding mesh 20. Screws smaller than the mesh size of the first layer of the vibrating feeding mesh 20 will pass through the mesh and fall onto the second layer of the vibrating feeding mesh 20 for vibrating transport. Screws smaller than the mesh size of the second layer of the vibrating feeding mesh 20 will pass through the mesh and fall onto the third layer of the vibrating feeding mesh 20 for vibrating transport. Throughout the process, screws of different specifications pass through the guide baffles 26 fixedly installed on the first, second, and third layers of the vibrating feeding mesh 20 and fall into different screw collection boxes 27 for collection. During the entire vibration transport process, the electric heating module 22 is in the starting heating state to dry the liquid adhering to the surface of the screws during the vibration transport process, thus completing the drying and sorting collection of the screws.

[0042] Reference Figure 7The screw collection box 27 has multiple guide blocks 28 fixedly installed at its bottom. The main body 1 of the cleaning device has slots 29 that match the guide blocks 28. The screw collection box 27 has a handle 30 on its outer side for easy pulling. The bottom of the handle 30 has a strip-shaped mounting block 31. A positioning rod 32 is movably installed inside the strip-shaped mounting block 31. Pull rods 33 are fixedly installed on both sides of the positioning rod 32 for easy pulling. The strip-shaped mounting block 31 has a limiting groove 34 for easy sliding of the pull rod 33. The positioning rod 32 is close to... A compression spring 35 is provided on one side of the handle 30. The two ends of the compression spring 35 are fixedly connected to the inner wall of the positioning rod 32 and the strip mounting block 31, respectively. A positioning block 36 is fixedly provided on the main body 1 of the cleaning device to facilitate the insertion of the positioning rod 32. Specifically, in this utility model, the design of the guide block 28, slot 29, handle 30, strip mounting block 31, positioning rod 32, pull rod 33, limiting slide 34, compression spring 35 and positioning block 36 facilitates the convenient installation of the screw collection box 27 in the main body 1 of the cleaning device.

[0043] When it is necessary to empty the screws from the screw collection box 27, the operator only needs to hold the handle 30 of the screw collection box 27, put their fingers down through the handle 30, and pull the lever 33 upward to pull the positioning rod 32 out of the positioning block 36. Then, the operator pulls the handle 30 to remove the screw collection box 27 from the main body 1 of the cleaning device. After emptying the screws from the screw collection box 27, the operator only needs to hold the handle 30 again and pull the lever 33 upward. Then, the guide block 28 set at the bottom of the screw collection box 27 is inserted into the slot 29. When the guide block 28 abuts against the inner wall of the slot 29, the operator releases the lever 33 to allow the positioning rod 32 to be reinserted into the positioning block 36, thus completing the convenient installation and removal of the screw collection box 27 from the main body 1 of the cleaning device.

[0044] The usage process of the screw production cleaning device provided by this utility model is as follows:

[0045] When cleaning screws of various sizes, the operator simply places the screws to be cleaned into the inner cylinder 5, then opens the solenoid valve at the water inlet 3 and controls the water inlet system connected to the water inlet 3 to deliver clean water into the inner cylinder 5. An appropriate amount of cleaning solution is then injected into the inner cylinder 5. The cylinder cover 7 is then closed, and the drive motor 8 is started to rotate the inner cylinder 5, allowing the water mixed with the cleaning solution to rinse the screws. During the rinsing process, the centrifugal force generated by the rotation of the inner cylinder 5 causes the screws to move towards the inner wall of the inner cylinder 5 and collide with the multiple cleaning brushes 10 installed on the inner wall. After thorough cleaning, open the solenoid valve at drain outlet 4 to allow the cleaning waste liquid in the inner cylinder 5 to flow out through the connecting sleeve 15 and drain outlet 4. During the entire cleaning process, repeated water intake and drainage remove the cleaning liquid and oil stains adhering to the screw surface. Then, start the drive motor 11 to rotate the cleaning cylinder 2 counterclockwise along the main body 1 of the cleaning device. During the rotation of the cleaning cylinder 2, the cylinder cover 7, hinged at the top of the cleaning cylinder 2, will continuously open, allowing the cleaned screws inside the cleaning cylinder 2 to be poured out. After the cleaning cylinder 2 has rotated 180 degrees, the drive motor 11 stops. For a period of time, keep the cylinder cover 7 fully open to empty all the cleaned screws from the cleaning cylinder 2. Then restart the drive motor 11 to rotate the cleaning cylinder 2 180 degrees counterclockwise to reset it, thus completing the unified emptying of the cleaned screws. The screws poured out of the cleaning cylinder 2 fall directly onto the vibrating feeder 20. At this time, the vibrating motor 21 starts, causing the screws to vibrate and be transported on the first layer of the vibrating feeder 20. Screws smaller than the mesh size of the first layer of the vibrating feeder 20 will pass through the mesh and fall onto the second layer of the vibrating feeder 20 for vibrating transport. Screws passing through the mesh of the second-layer vibrating feeder 20 fall onto the third-layer vibrating feeder 20 for vibrating conveying. Throughout the process, screws of different specifications fall into different screw collection boxes 27 through the guide baffles 26 fixed on the first, second, and third-layer vibrating feeders 20 for collection. During the entire vibrating conveying process, the electric heating module 22 is in the activated heating state to dry the liquid adhering to the surface of the screws during the vibrating conveying process, thus completing the cleaning, drying, and sorting collection of the screws.
