Description

Technical Field

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

[0002] During the production and processing of steel nails, the finished steel nails need to be sorted and arranged for subsequent packaging, storage and transportation. At present, the common methods of sorting and arranging steel nails mostly rely on manual operation, that is, manually placing the messy steel nails one by one, or using simple mechanical auxiliary tools, such as trays with grooves, to manually put the steel nails into the grooves to achieve initial arrangement. Some production lines with a slightly higher degree of automation will use equipment such as vibratory feeders to transport and initially sort the steel nails. The force generated by vibration will make the steel nails gradually adjust their posture in the conveyor track, and finally achieve a certain degree of orderly arrangement.

[0003] However, existing steel nail sorting and arrangement technologies have significant shortcomings in efficiency. Manual sorting not only consumes a lot of labor costs, but is also affected by the speed and fatigue of manual operation, resulting in low sorting efficiency and making it difficult to meet the needs of large-scale production. Even with mechanical assistance such as vibratory feeders, the special shape of steel nails makes them prone to jamming and stacking during vibration, requiring frequent machine stops for manual intervention. This leads to poor continuity in the overall sorting and arrangement, making it impossible to achieve efficient and stable automated operation, which seriously restricts the overall efficiency improvement of steel nail production. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a screw hole cleaning device. The scraper position can be adjusted by tightening bolts to adapt to different screw hole inner diameters. The drive device drives the rotating arm and scraper to clean the screw hole. At the same time, a water pump and atomizing nozzle are used for atomized spraying. Combined with the connection hole, an external fan is connected to the external fan and dust is extracted through the air extraction hole. This solves the problems of large amount of dust generated during cleaning and the difficulty in effectively controlling existing dust suppression methods, and the difficulty in cleaning the dust inside the hole.

[0006] To achieve the above objectives, this utility model proposes a screw hole cleaning device, comprising a support plate, a support column, a support head, a drive device, a rotating arm, a cleaning mechanism, and a support assembly. One end of the support column is fixedly connected to one side of the support plate, and the support head is fixedly connected to the other end of the support column. The drive device is installed at the end of the support head. One end of the rotating arm is rotatably connected to the other side of the support plate. The output end of the drive device passes through the support column and is fixedly connected to one end of the rotating arm. Multiple cleaning mechanisms are arranged in a circumferential array on the outer wall of the rotating arm. Each cleaning mechanism includes support bars, fastening bolts, scrapers, and a dustproof assembly. The support bars are symmetrically fixedly connected to the outer wall of the rotating arm. Multiple fastening bolts are threaded at equal intervals to the outer wall of the support bars. The scraper is embedded in the outer wall of the rotating arm, and the outer wall of the scraper is threadedly connected to the fastening bolts. The dustproof assembly is installed on one side of the support plate. The support assembly is provided between the support plate and the support head, and they are connected through the support assembly.

[0007] This utility model relates to a screw hole cleaning device. The operator holds the handle and inserts the device into the screw hole. The stabilizing plate, relying on its elasticity, adheres to the hole wall via an anti-slip pad. When the support head is pressed, the stabilizing plate drives the support arm to slide within the support sleeve, compressing the support spring. The process is smooth and linear. The drive motor is activated, and its output shaft, via a flexible coupling, drives the rotating arm to rotate. The rotating arm then drives the scraper of the cleaning mechanism to rotate. The scraper's extension length can be adjusted using fastening bolts to accommodate screw holes of different inner diameters and remove dirt. Simultaneously, an external fan draws dust through the connection hole and exhaust port, and the water pump of the dustproof component draws water through the inlet. The pipeline delivers water to the cavity of the support column and then to the atomizing nozzle. The atomizing nozzle sprays water mist into the screw holes to absorb dust. The drainage pipe removes excess water. After cleaning, the support head is released, and the support spring releases potential energy to push the support arm out of the support sleeve, causing the support head to quickly return to its original position. This device uses a scraper to efficiently clean different screw holes, combined with precise dust extraction through the air extraction hole and water mist spraying deep into the holes through the atomizing nozzle, forming a synergistic dust suppression mechanism. This solves the problems in the background technology where a large amount of dust is generated during cleaning and existing dust suppression methods are difficult to control effectively, and manual water spraying cannot penetrate deep into the holes to suppress dust in time.

[0008] In addition, the screw hole cleaning device proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the dustproof component includes a water pump, an inlet pipe, a drain pipe, and atomizing nozzles. The water pump is installed on one side of the support plate, and a cavity is formed inside the support column. The inlet pipe is provided between the water pump and the cavity and is connected through the inlet pipe. The drain pipe is provided between one side of the support plate and the water pump and is connected through the drain pipe. Multiple atomizing nozzles are fixedly connected to the other side of the support plate in a circumferential array.

[0010] Specifically, the support assembly includes a support sleeve, a support arm, a fixing plate, and a support spring. One end of each of the two support sleeves is symmetrically fixed to one side of the support plate. The fixing plate is symmetrically fixed to the outer wall of the support head. One end of the support arm is fixed to the inner wall of the fixing plate. The other end of the support arm slides through the other end of the support sleeve. The support spring is provided between the other end of the support arm and the inner wall end of the support sleeve, and is connected to the support arm through the support spring.

[0011] Specifically, a connection hole is provided on one side of the support plate for connecting an external fan, and multiple air extraction holes are installed in a circumferential array on the other side of the support plate.

[0012] Specifically, a handle is fixedly connected to one side of the support plate.

[0013] Specifically, the outer wall of the support plate is fixedly connected with multiple stabilizing plates in a circumferential array, and the inner wall of the stabilizing plates is fixedly connected with anti-slip pads.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The screw hole cleaning device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, the screw hole cleaning device of this utility model embodiment may include a support plate 1, a support column 2, a support head 3, a drive device 4, a rotating arm 5, a cleaning mechanism 6, and a support assembly 7.

[0027] One end of the support column 2 is fixedly connected to one side of the support plate 1, the support head 3 is fixedly connected to the other end of the support column 2, the drive device 4 is installed at the end of the support head 3, one end of the rotating arm 5 is rotatably connected to the other side of the support plate 1, the output end of the drive device 4 passes through the support column 2 and is fixedly connected to one end of the rotating arm 5.

[0028] Furthermore, a connection hole 11 is provided on one side of the support plate 1 for connecting an external fan, and multiple air extraction holes 13 are installed in a circumferential array on the other side of the support plate 1. A handle 12 is fixedly connected to one side of the support plate 1, and multiple stabilizing plates are fixedly connected in a circumferential array on the outer wall of the support plate 1. Anti-slip pads are fixedly connected to the inner wall of the stabilizing plates.

[0029] It should be noted that the driving device 4 described in this embodiment is a drive motor, and the support column 2 is a high-strength alloy steel pipe. One end is fixed to the center of one side of the support plate 1 by argon arc welding, and the weld is polished. The other end is detachably connected to the support head 3 by high-strength bolts. A rubber sealing gasket is provided at the connection between the two to prevent dust from entering. The support head 3 is integrally molded from engineering plastic and has an internal mounting cavity adapted to the driving device 4. The driving device 4 is fixedly installed by countersunk bolts. Its output shaft is concentric with the support column 2. A wear-resistant bushing is fitted on the outside of the output shaft. A gap is left between the bushing and the inner wall of the support column 2 to ensure flexible rotation of the output shaft while reducing dust intrusion. One end of the rotating arm 5 is connected to the groove on the other side of the support plate 1 by a precision ball bearing with a dust cover. The outer ring of the bearing is interference-fitted with the groove, and the inner ring is fixed to the rotating arm 5 by a key. The output end of the driving device 4 passes through the pre-set through hole inside the support column 2 and is connected to the end of the rotating arm 5 by a flexible coupling. The fixed connection can buffer the impact and vibration during rotation. Furthermore, the support plate 1 is made of thickened steel plate by stamping. The inner wall of the connecting hole 11 in the center of one side is provided with internal threads for connecting the air guide pipe of the external fan. The connecting hole 11 is connected to the air guide cavity inside the support plate 1. Multiple air extraction holes 13 arranged in a circumferential array on the other side of the support plate 1 are all connected to the air guide cavity. The diameter of the air extraction holes 13 gradually decreases from the inside to the outside to enhance the air extraction efficiency. The opening is rounded to avoid scratching the inner wall of the screw hole. A handle 12 is fixed to one side of the support plate 1 by welding. The handle 12 is made of rubber wrapped with a metal core and has anti-slip texture on the surface. Its position is consistent with the center of gravity of the support plate 1 for easy gripping. Four stabilizing plates are fixed in a circumferential array on the outer wall of the support plate 1. The stabilizing plates are made of elastic steel plate and have textured silicone anti-slip pads fixed on their inner walls. When the device is inserted into the screw hole, the stabilizing plate can fit tightly against the inner wall of the screw hole by its own elasticity. The anti-slip pads increase the friction to prevent shaking or displacement during cleaning.

[0030] The cleaning mechanism 6 is provided in multiple sets and is installed in a circumferential array on the outer wall of the rotating arm 5. The cleaning mechanism 6 includes a support bar 61, a fastening bolt 62, a scraper 63 and a dustproof component 64.

[0031] Among them, the support bar 61 is symmetrically fixedly connected to the outer wall of the rotating arm 5, and multiple fastening bolts 62 are threadedly connected to the outer wall of the support bar 61 at equal intervals. The scraper 63 is embedded in the outer wall of the rotating arm 5, and the outer wall of the scraper 63 is threadedly connected to the fastening bolts 62. The dustproof component 64 is installed on one side of the support plate 1. A support component 7 is provided between the support plate 1 and the support head 3, and they are connected through the support component 7.

[0032] It should be noted that the support bar 61 described in this embodiment is made of high-strength steel plate symmetrically welded to the outer wall of the rotating arm 5. Its surface is treated with anti-rust to enhance durability. Multiple fastening bolts 62 are threadedly connected to the outer wall of the support bar 61 at equal intervals. The bolt ends are equipped with anti-slip knobs for easy manual adjustment. The scraper 63 is made of wear-resistant rubber material and embedded in the outer wall of the rotating arm 5. Its edge is arc-shaped to fit the inner wall of the screw hole. The outer wall of the scraper 63 is threadedly connected to the fastening bolts 62. The extension length of the scraper 63 can be flexibly adjusted by tightening or loosening the bolts.

[0033] Specifically, the operator holds the handle 12 and inserts the device into the screw hole. The stabilizing plate is fixed to the hole wall by the anti-slip pad under its own elasticity. The drive motor 4 is started, and its output shaft drives the rotating arm 5 to rotate through the elastic coupling. The rotating arm 5 drives the scraper 63 of the cleaning mechanism 6 to rotate. The extension length of the scraper 63 can be adjusted by the fastening bolt 62 to adapt to screw holes with different inner diameters, so that the scraper 63 can make close contact with the hole wall and scrape off the dirt. At the same time, the external fan draws away the dust in the hole through the connecting hole 11 and the air extraction hole 13. The dustproof component 64 assists in dust reduction, and the support component 7 enhances the overall stability of the device. In this process, the air extraction structure and the cleaning mechanism 6 work synchronously. The air extraction hole 13 can accurately target the dust generation area to extract dust, which solves the problem of large amount of dust generated during cleaning and the difficulty of effectively controlling the existing dust reduction methods in the background technology.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, the dustproof component 64 includes a water pump 641, a water inlet pipe 642, a drain pipe 643, and an atomizing nozzle 644. The water pump 641 is installed on one side of the support plate 1. A cavity is opened in the support column 2. The water pump 641 is connected to the cavity through the water inlet pipe 642. A drain pipe 643 is provided between one side of the support plate 1 and the water pump 641 and is connected through the drain pipe 643. Multiple atomizing nozzles 644 are fixedly connected to the other side of the support plate 1 in a circumferential array.

[0035] It should be noted that the water pump 641 of the dustproof component 64 described in this embodiment is fixed to one side of the support plate 1 by bolts. It is made of corrosion-resistant material to adapt to different water qualities. The cavity inside the support column 2 is sealed to form a water delivery channel. The water inlet pipe 642 between the water pump 641 and the cavity is a flexible pressure-resistant pipe with a sealing ring at the interface to prevent leakage. The drainage pipe 643 between one side of the support plate 1 and the water pump 641 is also a pressure-resistant pipe to facilitate the discharge of excess water. Multiple atomizing nozzles 644 are fixed in a circumferential array on the other side of the support plate 1. The nozzle angle can be adjusted to cover the inner wall of the screw hole. The sprayed water mist can quickly adsorb dust and enhance the dust reduction effect.

[0036] Specifically, after the water pump 641 starts, water is transported to the sealed cavity inside the support column 2 through the water inlet pipe 642, and then the water is led to the atomizing nozzle 644 through the relevant passage. The atomizing nozzle 644 atomizes the water and sprays it into the screw hole. At the same time, the drainage pipe 643 can drain excess water to avoid water accumulation. This component accurately sprays water mist onto the dust-generating area through the atomizing nozzle 644, so that the dust is quickly adsorbed. Combined with the dust extraction effect of the external fan, it effectively solves the problem in the background technology that a large amount of dust is generated during cleaning and that existing dust suppression methods such as manual water spraying cannot penetrate into the hole in time to suppress the dust.

[0037] In one embodiment of this utility model, such as Figures 1-4 As shown, the support assembly 7 includes a support sleeve 71, a support arm 72, a fixing plate 73, and a support spring 74. One end of each of the two support sleeves 71 is symmetrically fixed to one side of the support plate 1. The fixing plate 73 is symmetrically fixed to the outer wall of the support head 3. One end of the support arm 72 is fixed to the inner wall of the fixing plate 73. The other end of the support arm 72 slides through the other end of the support sleeve 71. A support spring 74 is provided between the other end of the support arm 72 and the inner wall end of the support sleeve 71, and they are connected by the support spring 74.

[0038] It should be noted that the support sleeve 71 of the support component 7 described in this embodiment is made of high-strength metal tube, with one end symmetrically welded to one side of the support plate 1. The tube opening is polished to reduce friction. The fixing plate 73 is made of metal sheet, symmetrically welded to the outer wall of the support head 3 to enhance connection stability. The support arm 72 is made of wear-resistant metal rod, with one end welded and fixed to the inner wall of the fixing plate 73, and the other end sliding through the support sleeve 71. The outer wall is smoothed to ensure smooth sliding. The support spring 74 is a high-strength compression spring, with both ends fixedly connected to the end of the support arm 72 and the end of the inner wall of the support sleeve 71, respectively. It can buffer the vibration during operation of the elastic telescopic device and enhance the overall structural stability.

[0039] Specifically, when the support head 3 is pressed, the fixing plate 73 drives the support arm 72 to slide into the support sleeve 71, and the support spring 74 is compressed. Since the outer wall of the support arm 72 is smooth and fits precisely with the support sleeve 71, the pressing process is smooth and linear. After cleaning, the pressure on the support head 3 is released, and the compressed support spring 74 releases its elastic potential energy, pushing the support arm 72 to slide out of the support sleeve 71, causing the support head 3 to quickly reset. This structure ensures the smoothness and efficiency of the pressing and resetting actions, guarantees the continuity of the cleaning operation, indirectly improves the stability of dust control, and helps solve the dust problem in the background technology.

[0040] In summary, in the screw hole cleaning device of this utility model embodiment, the operator holds the handle 12 and inserts the device into the screw hole. The stabilizing plate is fixed to the hole wall by elasticity through the anti-slip pad. When the support head 3 is pressed, the fixing plate 73 drives the support arm 72 to slide in the support sleeve 71, compressing the support spring 74. The process is smooth and linear. The drive motor drive device 4 is started, and its output shaft drives the rotating arm 5 to rotate through the elastic coupling. The rotating arm 5 drives the scraper 63 of the cleaning mechanism 6 to rotate. The extension length of the scraper 63 can be adjusted by the fastening bolt 62 to adapt to screw holes with different inner diameters and scrape off dirt. At the same time, the external fan sucks dust through the connection hole 11 and the air extraction hole 13. The water pump 641 of the dustproof component 64 Water is transported through the inlet pipe 642 to the cavity of the support column 2 and then to the atomizing nozzle 644. The atomizing nozzle 644 sprays water mist into the screw hole to absorb dust. The drain pipe 643 drains excess water. After cleaning, the support head 3 is released, and the support spring 74 releases potential energy to push the support arm 72 out of the support sleeve 71, causing the support head 3 to quickly reset. This device uses the scraper 63 to efficiently clean different screw holes, combined with the air extraction hole 13 for precise dust extraction and the atomizing nozzle 644 to spray water mist deep into the hole, forming a synergistic dust suppression mechanism. This solves the problems in the background technology where a large amount of dust is generated during cleaning and existing dust suppression methods are difficult to control effectively, and manual water spraying cannot penetrate deep into the hole to suppress dust in time.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
