Description

Technical Field

[0001] This utility model belongs to the field of bolt cleaning technology, and specifically relates to a bolt cleaning machine. Background Technology

[0002] In the field of bolt cleaning technology, traditional processes mostly rely on manual brushing or chemical soaking, which are not only inefficient and unable to meet the needs of modern mass production, but also pose risks to occupational health and environmental pollution. In particular, the strong acid and alkali solvents used in chemical cleaning processes pose a threat to the safety of operators. At the same time, the cleaning quality is greatly affected by the individual operator's skill level, resulting in a lack of consistency in product cleanliness, which in turn affects the quality of subsequent assembly.

[0003] In recent years, to improve cleaning efficiency, the industry has begun to introduce automated cleaning equipment. The mainstream solution adopts an axial travel design, using a conveyor belt to transport bolts to a double-roller cleaning area, where a rotating wire brush completes the surface treatment. However, this type of equipment still has significant drawbacks in practical applications. For example, the alignment accuracy between the bolts and the conveyor belt / rollers during the feeding process is extremely high; even slight deviations can lead to unstable material transport or even splashing. The unloading process largely relies on manual operation, resulting in low automation and preventing continuous operation of cleaning and maintenance processes. Furthermore, the transmission mechanism often uses exposed chain drives, which not only leads to low mechanical safety but also affects equipment reliability and increases maintenance costs. Utility Model Content

The feeding mechanism is located at the inlet end at the front of the frame and is used to push the bolts to the cleaning mechanism; The cleaning mechanism is located at the discharge end of the feeding mechanism. The cleaning mechanism includes a fixed roller and a moving roller that rotate in opposite directions. The fixed roller is located on one side near the discharge end of the feeding mechanism. The fixed roller is connected to the drive assembly, and the moving roller is connected to the spacing adjustment assembly. A brush assembly is provided above the fixed roller and the moving roller for cleaning the surface of the bolt.

The feeding mechanism located at the front of the frame can stably transport bolts to the cleaning mechanism, effectively avoiding the inefficiency and safety hazards of manual feeding and improving the accuracy and continuity of feeding. The cleaning mechanism uses counter-rotating fixed and moving rollers, which, in coordination with the brush assembly, can achieve comprehensive cleaning of the bolt surface. The distance between the fixed and moving rollers can be adjusted by the distance adjustment component to accommodate bolts of different diameters, ensuring the stability and consistency of the cleaning effect and improving cleaning quality and efficiency. The dust removal mechanism below the main structure uses negative pressure to collect dust generated during the cleaning process, effectively preventing dust pollution to the bolt cleaning machine and the environment. The oiling mechanism located at the discharge end of the dust removal mechanism automatically applies oil to the cleaned bolts, ensuring uniform protection of the bolt surface and effectively preventing corrosion and damage during transportation and use, thus extending the bolts' service life. The unloading mechanism located at the discharge end of the oiling mechanism smoothly discharges the oiled bolts, avoiding secondary damage during unloading and ensuring the integrity and quality of the finished bolts. The control system is electrically connected to the feeding mechanism, cleaning mechanism, dust removal mechanism, oiling mechanism, and unloading mechanism, enabling precise control and real-time monitoring of each stage of the bolt cleaning machine. This allows operators to monitor the machine's operating status in real time, greatly improving the ease of operation and production efficiency of the bolt cleaning machine.

Combined with the first lead screw motor driving the first lead screw in the spacing adjustment component, the precise displacement adjustment of the moving roller is realized, so that the bolt cleaning machine can adapt to the cleaning needs of bolts with different diameters of 24-65mm, and improve the applicability of the bolt cleaning machine to bolts of multiple specifications and the consistency of cleaning quality.

[0012] Furthermore, the brush assembly includes a brush roller and a plurality of brushes disposed on the brush roller.

[0015] The beneficial effects of adopting the above technical solution are as follows: when the lifting motor is started, it can drive the lifting rod to rise and fall, thereby driving the lifting bracket and the second fixed base plate to slide vertically along the second guide rail on the vertical fixed rod, realizing the height adjustment of the brush roller to adapt to the cleaning needs of bolts of different heights, ensuring the comprehensiveness and uniformity of the cleaning process, and improving the applicability and cleaning quality of the bolt cleaning machine.

[0016] Furthermore, a brush guard is provided on the outside of the brush roller, with one end of the brush guard disposed on the first fixed base plate and the other end of the brush guard disposed on the second fixed base plate.

[0017] The beneficial effects of adopting the above technical solution are as follows: the two ends of the brush guard are fixed on the first fixed base plate and the second fixed base plate respectively, which can form a closed protective structure to prevent dust from overflowing and brushes from falling off during the cleaning process. At the same time, the brush guard can be raised and lowered synchronously with the brush roller, which not only ensures the safety of the rotation operation, but also avoids interference between the brush guard and the bolt or bolt cleaning machine, thereby improving the cleanliness and reliability of the bolt cleaning machine.

[0018] Furthermore, the dust removal mechanism includes an inclined material discharge roller frame, which is located below the fixed roller and the moving roller.

[0019] The beneficial effects of adopting the above technical solution are as follows: the dust removal mechanism, through the synergistic effect of the inclined material drop roller and the dust removal through hole, allows the dust generated during cleaning to fall naturally into the negative pressure box. At the same time, the exhaust fan generates negative pressure airflow to efficiently suck the dust into the detachable dust collection bag, forming a complete dust collection system. This ensures that the dust is separated and collected in time during the bolt cleaning process, thereby avoiding secondary pollution.

[0020] Furthermore, the oiling mechanism includes an oil supply tank, which is disposed between the transverse support rods.

The other end of the fixed support rod is connected to the transverse support rod.

[0021] The beneficial effects of adopting the above technical solution are as follows: the oiling mechanism, through the synergistic action of the oil supply tank and the oil brush roller, can continuously supply oil to the oil brush roller from the oil supply tank, while the third rotary motor drives the fourth rotary shaft to rotate the oil brush roller, so that the grease is evenly coated on the surface of the cleaned bolts; at the same time, the fixed support rod firmly connects the oil brush roller to the transverse support rod, ensuring the stability of the rotation process, thereby realizing automated oiling and maintenance, avoiding interference with the cleaning process, improving the quality of bolt surface treatment and the reliability of bolt cleaning machine operation.

[0022] Furthermore, the discharge end of the unloading roller is equipped with an oiling plate, the two sides of which are connected to one end of the second push rod, and the other end of the second push rod is connected to the output end of the second push rod motor, which is mounted on the transverse support rod.

[0023] The beneficial effects of adopting the above technical solution are as follows: the oiling plate set at the discharge end of the unloading roller is driven by the second push rod motor to realize the precise horizontal pushing action of the oiling plate, so that the cleaned bolts can smoothly enter the oiling process.

The unloading mechanism includes an inclined discharge slide plate, the high end of which is located below the discharge end of the oiling plate, and the bottom end of which extends to the outside of the rear end of the frame.

[0025] The beneficial effects of adopting the above technical solution are as follows: the unloading mechanism is connected to the discharge end of the oiling plate through the inclined discharge slide plate, and the bolts that have completed the cleaning and oiling process can be naturally slid off to the outside of the frame by gravity, thereby realizing fully automated material discharge.

[0026] In summary, the bolt cleaning machine provided by this utility model has the following beneficial effects: (1) The bolt cleaning machine integrates feeding, cleaning, dust removal, oiling and unloading mechanisms, combined with the control system, to realize the full-process automated operation from bolt cleaning to maintenance. It has a compact structure, small footprint, and can be used for bolts of various specifications with diameters of 24-65mm. It not only improves cleaning efficiency and cleaning quality, but also solves the problems of traditional bolt cleaning machines being bulky, having single function, low efficiency and unstable cleaning quality.

[0027] (2) The feeding mechanism in the bolt cleaning machine realizes the automated and precise pushing of bolts through the coordinated action of the push plate and the roller. The push plate can stably push the bolts in the feeding tray to the roller under the drive of the first push rod motor, avoiding the efficiency loss and operational risks of manual feeding. The feeding mechanism and the cleaning mechanism are seamlessly connected, ensuring the positioning accuracy of the bolts during the transmission process and providing a stable foundation for the subsequent cleaning process.

[0028] (3) The cleaning mechanism in this bolt cleaning machine adopts a structure in which the fixed roller and the moving roller rotate in opposite directions. Combined with the vertical lifting adjustment function of the brush assembly, it realizes comprehensive cleaning of bolts of different specifications. The fixed roller is kept rotating stably by belt drive, while the moving roller is driven by the first screw motor to realize automatic spacing adjustment, ensuring the adaptability of cleaning bolts with a diameter of 24-65mm. The brush assembly can rotate horizontally under the drive of the bevel gear transmission system. Combined with the vertical displacement of the lifting bracket, the brush can dynamically fit the bolt surface, solving the problem of limited cleaning range of traditional bolt cleaning machines.

[0029] (4) The dust removal mechanism in the bolt cleaning machine achieves efficient collection of cleaning dust through the coordinated action of the inclined unloading roller, the negative pressure box and the exhaust fan. The dust removal through holes on the unloading roller allow the dust to fall naturally into the negative pressure box. The negative pressure airflow generated by the exhaust fan sucks the dust into the detachable dust collection bag, forming a complete dust collection closed loop, thereby effectively preventing dust overflow and secondary pollution.

[0030] (5) The oiling mechanism in the bolt cleaning machine achieves automated oiling and maintenance of the bolts after cleaning through the coordinated action of the oil supply tank and the oil brush roller. The oil supply tank continuously supplies oil to the oil brush roller, and the third rotary motor drives the oil brush roller to rotate, so that the grease is evenly coated on the bolt surface. The fixed support rod firmly connects the oil brush roller to the horizontal support rod, ensuring the stability of the rotation process and avoiding the problem of uneven oiling.

[0031] (6) The unloading mechanism in the bolt cleaning machine achieves a fully automated closed loop of bolt processing through the coordinated action of the discharge slide plate and the oiling plate. The oiling plate, driven by the second push rod motor, can accurately push the cleaned and oiled bolts to the discharge slide plate. The bolts slide naturally down the inclined slide plate to the outside of the frame, avoiding the safety hazards of manual unloading and effectively improving the cleaning efficiency.

[0035] The bolt cleaning machine's frame 1 is constructed with several vertical support rods 12 and horizontal support rods 11 to form a stable framework. An external shell 13 provides a solid support foundation and effectively protects the internal mechanisms from external environmental interference, ensuring the stability and safety of the bolt cleaning machine's operation. The feeding mechanism 2, located at the front inlet of the frame 1, stably transports bolts to the cleaning mechanism 6, effectively avoiding the inefficiency and safety hazards of manual feeding and improving the accuracy and continuity of feeding. The cleaning mechanism 6 uses opposing rotating fixed rollers 61 and moving rollers 62, which, in conjunction with the brush 614 assembly, achieve comprehensive cleaning of the bolt surface. The distance between the fixed rollers 61 and moving rollers 62 can be adjusted by a distance adjustment component to accommodate bolts of different diameters, ensuring the stability and consistency of the cleaning effect and improving cleaning quality and efficiency. The dust removal mechanism 3 below can collect the dust generated during the cleaning process using negative pressure, effectively preventing dust pollution to the bolt cleaning machine and the environment. The oiling mechanism 4, located at the discharge end of the dust removal mechanism 3, can automatically apply oil to the cleaned bolts, ensuring uniform protection of the bolt surface and effectively preventing corrosion and damage during transportation and use, thus extending the service life of the bolts. The unloading mechanism 5, located at the discharge end of the oiling mechanism 4, can smoothly discharge the oiled bolts, avoiding secondary damage to the bolts during the unloading process and ensuring the integrity and quality of the finished bolts. The control system is electrically connected to the feeding mechanism 2, cleaning mechanism 6, dust removal mechanism 3, oiling mechanism 4, and unloading mechanism 5, realizing precise control and real-time monitoring of each link of the bolt cleaning machine. This allows operators to keep track of the operating status of the bolt cleaning machine in real time, greatly improving the ease of operation and production efficiency of the bolt cleaning machine.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the feeding mechanism 2 includes a feeding tray 21, a push plate 22 at the discharge end of the feeding tray 21, and a roller track 23 at the discharge end of the push plate 22. The lower end of the push plate 22 is connected to one end of a first push rod 24, and the other end of the first push rod 24 is connected to the output end of a first push rod motor 25, which is mounted on a transverse support rod 11.

Driven by the first push rod motor 25, the push plate 22 stably pushes the bolts from the feeding tray 21 to the roller track 23, avoiding the efficiency loss and operational risks of manual feeding. Furthermore, it ensures a seamless connection between the feeding process and subsequent cleaning procedures, improving the continuity and operational efficiency of the overall process.

[0037] like Figure 4As shown, the drive assembly includes a first rotary motor 63, with a first rotary shaft 64 at the output end of the first rotary motor 63. A drive pulley 65 is mounted on the first rotary shaft 64, and the drive pulley 65 is connected to a driven pulley 67 via a belt 66. The driven pulley 67 is located at one end of a fixed roller 61, and first fixed bases 68 are located at both ends of the fixed roller 61. The first fixed bases 68 are mounted on a transverse support rod 11. The spacing adjustment assembly includes a first lead screw motor 611 and a first lead screw 612 located at the output end of the first lead screw motor 611. The first lead screw motor 611 is mounted on the transverse support rod 11, and the first lead screw 612 is threadedly connected to a first sliding base 69. The first sliding base 69 is located at both ends of a moving roller 62 and is slidably connected to a first guide rail 610, which is mounted on the transverse support rod 11. The drive assembly drives the active pulley 65 via the first rotary motor 63, which in turn drives the fixed roller 61 to rotate via the belt 66. The moving roller 62 is slidably connected to the first guide rail 610 via the first sliding base 69. Combined with the first lead screw motor 611 driving the first lead screw 612 in the spacing adjustment assembly, the precise displacement adjustment of the moving roller 62 is achieved.

[0038] like Figure 2 , Figure 5 and Figure 6As shown, the brush assembly includes a brush roller 613 and a plurality of brushes 614 disposed on the brush roller 613. One end of the brush roller 613 is disposed on a first fixed base plate 615, which is slidably connected to a second guide rail 15. The second guide rail 15 is disposed on a plurality of vertical fixed rods 14, which are correspondingly disposed on a horizontal support rod 11. The other end of the brush roller 613 is connected to one end of a second rotating shaft 616, which is provided with a first bevel gear 617. The first bevel gear 617 is meshed with a second bevel gear 618, which is disposed on a third rotating shaft 619.

The other end of the brush roller 613 and the second rotating motor 620 are disposed on a second fixed base plate 621, which is slidably connected to the second guide rail 15. By using the vertical fixing rod 14 in conjunction with the second guide rail 15, the brush assembly can slide vertically along the second guide rail 15, thereby achieving the lifting and lowering adjustment of the brush roller 613. At the same time, by adopting the meshing connection of the first bevel gear 617 and the second bevel gear 618, when the second rotary motor 620 is started, it drives the third rotary shaft 619 to rotate. Through the meshing transmission of the second bevel gear 618 and the first bevel gear 617, the brush roller 613 is driven to rotate horizontally. This not only ensures that the brush 614 can fully cover and clean bolts of different specifications, but also improves the rotational stability and enhances the adaptability of the bolt cleaning machine to bolts of multiple specifications and the uniformity of cleaning.

[0039] like Figure 2 As shown, a brush cover 626 is provided on the outside of the brush roller 613. One end of the brush cover 626 is disposed on the first fixed base plate 615, and the other end of the brush cover 626 is disposed on the second fixed base plate 621. The two ends of the brush cover 626 are fixed to the first fixed base plate 615 and the second fixed base plate 621 respectively, forming a closed protective structure to prevent dust from overflowing and the brush 614 from falling off during the cleaning process. At the same time, the brush cover 626 can be raised and lowered synchronously with the brush roller 613, which not only ensures the safety of the rotation operation, but also avoids interference between the brush cover 626 and the bolt or bolt cleaning machine, thereby improving the cleanliness and reliability of the bolt cleaning machine.

[0040] like Figure 5 and Figure 6As shown, a second rotating shaft 616 is mounted through a lifting bracket 622. The lifting bracket 622 is connected to a lifting assembly, which includes a lifting motor 623. A lifting rod 624 is mounted at the output end of the lifting motor 623. The lifting rod 624 passes through a lifting motor bracket 625, which is slidably connected to a second guide rail 15. The second guide rail 15 is mounted on two horizontally arranged vertical fixed rods 14. The lifting rod 624 is connected to the lifting bracket 622, and the lifting bracket 622 is connected to a second fixed base plate 621. When the lifting motor 623 is started, it drives the lifting rod 624 to rise and fall, thereby causing the lifting bracket 622 and the second fixed base plate 621 to slide vertically along the second guide rail 15 on the vertical fixed rods 14. This allows for height adjustment of the brush roller 613 to accommodate the cleaning needs of bolts of different heights, ensuring the comprehensiveness and uniformity of the cleaning process and improving the applicability and cleaning quality of the bolt cleaning machine.

[0041] like Figure 2 and Figure 7 As shown, the dust removal mechanism 3 includes an inclined material discharge roller 31, which is located below the fixed roller 61 and the moving roller 62. The material discharge roller 31 has several dust removal through holes 32. A negative pressure box 33 is located below the material discharge roller 31. The negative pressure box 33 is electrically connected to the exhaust fan 34. A dust collection constriction 35 is located at the upper end of the negative pressure box 33, and a detachable dust collection bag is located at the bottom end of the dust collection constriction 35. A side door 36 is located on the side of the negative pressure box 33 facing the front feed end of the frame 1. Through the synergistic effect of the inclined material discharge roller 31 and the dust removal through holes 32, the dust removal mechanism 3 allows the dust generated during cleaning to fall naturally into the negative pressure box 33. At the same time, the exhaust fan 34 generates a negative pressure airflow to efficiently suck the dust into the detachable dust collection bag. The side door 36 allows the operator to quickly clean the dust collection bag, thus forming a complete dust collection system. This ensures that the dust is separated and collected in time during the bolt cleaning process, avoiding secondary pollution.

[0042] like Figure 2 and Figure 7As shown, the oiling mechanism 4 includes an oil supply tank 41, which is disposed between the transverse support rods 11.

One end of the fourth rotating shaft is connected to the output end of the third rotating motor 45, and both ends of the fourth rotating shaft are connected to one end of the fixed support rod 47 through the third fixed base plate 46. The other end of the fixed support rod 47 is connected to the transverse support rod 11. The oiling mechanism 4, through the coordinated action of the oil supply tank 41 and the oil brush roller 44, can continuously supply oil to the oil brush roller 44 through the oil supply tank 41, while the third rotary motor 45 drives the fourth rotary shaft to rotate the oil brush roller 44, so that the grease is evenly coated on the surface of the cleaned bolts; at the same time, the fixed support rod 47 firmly connects the oil brush roller 44 to the transverse support rod 11, ensuring the stability of the rotation process. Thus, it not only realizes automated oiling and maintenance, but also avoids interference with the cleaning process, improves the quality of bolt surface treatment and the reliability of bolt cleaning machine operation.

[0043] like Figure 2 and Figure 7 As shown, an oiling plate 48 is provided at the discharge end of the unloading roller 31. Both sides of the oiling plate 48 are connected to one end of a second push rod 49, and the other end of the second push rod 49 is connected to the output end of a second push rod motor 410. The second push rod motor 49 is mounted on the transverse support rod 11. The oiling plate 48 at the discharge end of the unloading roller 31 drives the second push rod 49 via the second push rod motor 410, achieving precise horizontal pushing of the oiling plate 48. This allows the cleaned bolts to smoothly enter the oiling process, ensuring that the bolts contact the oiling roller 44 promptly for protective coating treatment after surface cleaning, thus improving the continuity and efficiency of the maintenance process.

[0044] like Figure 2 and Figure 7 As shown, the unloading mechanism 5 is located at the rear end of the frame 1. The unloading mechanism 5 includes an inclined discharge slide plate 51. The high end of the discharge slide plate 51 is located below the discharge end of the oiling plate 48, and the bottom end of the discharge slide plate 51 extends to the outside of the rear end of the frame 1. The unloading mechanism 5 is connected to the discharge end of the oiling plate 48 through the inclined discharge slide plate 51. It can use gravity to allow the bolts that have completed the cleaning and oiling processes to naturally slide off to the outside of the frame 1, thereby realizing fully automated unloading.

[0045] The bolt cleaning machine of this utility model operates as follows: At the start of the bolt cleaning process, the operator places the bolts to be cleaned into the feeding tray 21. The feeding mechanism 2 pushes the bolts to the cleaning mechanism 6 via the push plate 22 and the roller track 23. The cleaning mechanism 6 employs a fixed roller 61 and a moving roller 62 rotating in opposite directions. The spacing between the moving rollers 62 can be adjusted by the first lead screw 612 and the first lead screw motor 611 to accommodate bolts of different diameters. Simultaneously, the brush assembly is vertically adjusted under the drive of the lifting motor 623, ensuring thorough cleaning of the bolt surface. Dust generated during the cleaning process is removed by the dust removal mechanism 3 below. The negative pressure dust collection system efficiently collects dust and prevents environmental pollution. After cleaning, the bolts fall onto the unloading roller 31 and then enter the oiling mechanism 4 for oiling. The oiling mechanism 4, through the coordinated action of the oil supply tank 41 and the oil brush roller 44, evenly coats the grease onto the bolt surface to form a protective layer. Finally, the oiling plate 48 guides the finished bolts to the discharge slide plate 51, completing the entire processing flow. Throughout the process, the control system can monitor the operating status of each process in real time. Operators can view information such as the number of bolts processed and the status of the bolt cleaning machine on the display screen, realizing intelligent operation and management.

[0046] In summary, the bolt cleaning machine provided by this utility model integrates feeding, cleaning, dust removal, oiling, and unloading mechanisms, combined with a control system, to achieve fully automated operation from bolt cleaning to maintenance. It has a compact structure, small footprint, and can be used for bolts of various specifications with diameters of 24-65mm. It not only improves cleaning efficiency and quality, but also solves the problems of traditional bolt cleaning machines being bulky, having limited functions, low efficiency, and unstable cleaning quality.
