Description

Technical Field

[0001] This invention relates to the field of bolt rust removal technology, and in particular to a bolt rust removal device. Background Technology

[0002] Bolts are commonly used fasteners and are widely used in construction. After long-term use or storage, bolts are prone to rust. The relevant technology usually uses manual rust removal to remove rust and oil stains from bolts. This rust removal method has the problems of low rust removal efficiency and time and labor.

[0003] To address the aforementioned problems, existing technicians have designed bolt rust removal devices. These devices create a cleaning zone using two opposing cleaning brushes. During rust removal, the rusted bolt is connected to an electric wrench, which is then activated. The bolt is then inserted into the cleaning zone between the two brushes, and the electric wrench rotates the bolt, allowing the brushes to remove rust and oil. Compared to traditional manual rust removal methods, this existing device reduces the intensity of manual labor to some extent. However, this current device has a limited function, only capable of simple bolt rust removal and unable to perform batch rust removal, resulting in low rust removal efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1 to 10 As shown, the bolt rust removal device of this embodiment includes a roller assembly rust removal device 100, a rust removal and cleaning device 200, a mechanical claw transport device 300, and a drying and oiling device 400.

[0038] The roller assembly rust removal device 100 includes a front support 1, an induction spraying device 2, and an upper rust removal roller assembly 3 and a lower rust removal roller assembly 4 that cooperate with each other. The induction spraying device 2, the upper rust removal roller assembly 3, and the lower rust removal roller assembly 4 are respectively mounted on the front support 1. The upper rust removal roller assembly 3 and the lower rust removal roller assembly 4 are arranged alternately to form a rust removal roller channel. The induction spraying device 2 is located at the front end of the upper rust removal roller assembly 3. During operation, bolts can be conveyed from front to back along the rust removal roller channel. When the induction spraying device 2 senses that the bolt has entered the rust removal roller channel, rust remover is sprayed. The bolts sprayed with rust remover can achieve preliminary rust removal through the rolling friction between the upper rust removal roller assembly 3 and the lower rust removal roller assembly 4.

[0039] The rust removal and cleaning device 200 is located at the rear end of the roller assembly rust removal device 100. The rust removal and cleaning device 200 includes a stainless steel cleaning chamber 5, which is equipped with an ultrasonic generator 6 and an electromagnetic generator 7. The stainless steel cleaning chamber 5 contains water with added rust remover. Bolts that have undergone rust removal by the roller assembly rust removal device 100 fall into the stainless steel cleaning chamber 5 and roll from front to back. During this rolling process, the ultrasonic generator 6 performs ultrasonic rust removal on the bolts inside the stainless steel cleaning chamber 5. The removed rust is adsorbed onto the inner wall of the stainless steel cleaning chamber 5 under the action of the electromagnetic generator 7, thus achieving the cleaning operation of the bolts.

[0040] The mechanical claw transport device 300 is located at the rear end of the rust removal and cleaning device 200 and at the front end of the drying and oiling device 400. The mechanical claw transport device 300 includes a mechanical claw bracket 8 and a mechanical claw mechanism 9 installed on the mechanical claw bracket 8. The mechanical claw mechanism 9 can grab and transport the bolts in the stainless steel cleaning box 5 to the front inlet of the drying and oiling roller channel of the drying and oiling device 400.

[0041] The drying and oiling device 400 is installed at the rear end of the rust removal and cleaning device 200. The drying and oiling device 400 includes a rear support 10, an induction spraying device 11, a drying lamp, and an upper oiling roller assembly 12 and a lower oiling roller assembly 13 that cooperate with each other. The induction spraying device 11, the drying lamp, the upper oiling roller assembly 12 and the lower oiling roller assembly 13 are respectively installed on the rear support 10. The upper oiling roller assembly 12 and the lower oiling roller assembly 13 are arranged alternately to form a drying and oiling roller channel. The drying lamp is located at the front of the upper oiling roller assembly 12 and the lower oiling roller assembly 13, respectively. The induction spraying device 11 is located at the rear of the upper oiling roller assembly 12. After rust removal and cleaning, the bolts can be conveyed along the drying and oiling roller channel. The bolts are first dried by a drying lamp at the front of the drying and oiling roller channel. Then, when the bolts are conveyed to the rear of the drying and oiling roller channel and are sensed by the induction oil spraying device 11, the induction oil spraying device 11 performs an oil spraying operation to achieve oiling and maintenance of the bolts. After oiling, the bolts are discharged through the outlet of the drying and oiling roller channel.

[0042] Therefore, the bolt rust removal device of this invention integrates multiple functions such as bolt rust removal, bolt cleaning, drying and oiling maintenance into one unit, resulting in more thorough rust removal, better rust removal effect, and the ability to perform batch rust removal operations on bolts, effectively improving rust removal efficiency.

[0043] In some embodiments of the present invention, a bolt feeding box 500 is provided above the roller assembly rust removal device 100, and the bolt feeding box 500 is mounted on the front end bracket 1. The bottom outlet 26 of the bolt feeding box 500 is connected to the upper inlet of the arc-shaped track 600, and the lower outlet of the arc-shaped track 600 corresponds to the front port of the rust removal roller channel. That is, a batch of bolts can be fed through the bolt feeding box 500 and transported through the arc-shaped track 600 to the rust removal roller channel of the roller assembly rust removal device 100.

[0044] The bolt feeding box 500 includes a rectangular feeding box body 14. At the bottom of the feeding box body 14, a first bolt track 15 is provided, gradually sloping upwards from front to back. First bolt head limiting grooves 16 are respectively provided on the left and right sides of the first bolt track 15. A bolt outlet is located at the front bottom of the feeding box body 14, and the bolt outlet is connected to the upper inlet of the arc-shaped track 600. That is, bolts inserted into the feeding box body 14 can slide along the inclined surface of the first bolt track 15 from the rear end to the front end of the feeding box body 14, and fall into the arc-shaped track 600 through the bolt outlet at the front bottom. After passing through the arc-shaped track 600, they are conveyed to the rust-removing roller channel. The first bolt head limiting grooves 16 on the left and right sides of the first bolt track 15 allow the bolt heads inserted into the feeding box body 14 to slide along the first bolt head limiting grooves 16, and the bolt shanks to slide along the first bolt track 15, thereby achieving orderly bolt conveying.

[0045] In some embodiments of the present invention, the upper rust removal roller group 3 includes a plurality of upper rust removal rollers arranged in a horizontal direction, and the lower rust removal roller group 4 includes a plurality of lower rust removal rollers arranged in a horizontal direction. Each upper rust removal roller and each lower rust removal roller is driven by a motor to rotate. Furthermore, each upper rust removal roller and each lower rust removal roller is wrapped with steel wire on its outer periphery to achieve a better rust removal effect when the bolt passes through the rolling friction between the upper rust removal rollers and the lower rust removal rollers.

[0046] In some embodiments of the present invention, the stainless steel cleaning chamber 5 is formed by a bottom plate, a front side plate, a rear side plate, a left side plate, and a right side plate, wherein the front side plate is located below the rear port of the rust-removing roller channel. A second bolt track 17, which gradually slopes downwards from front to back, is provided on the upper surface of the bottom plate, and second bolt head limiting grooves 18 are respectively provided on the left and right sides of the second bolt track 17. A horizontal gripping area 19 is provided on the bottom plate near the rear side plate, and slag collection troughs 20 are respectively provided on the left and right sides of the horizontal gripping area 19. That is, bolts output from the rear port of the rust-removing roller channel can fall directly into the stainless steel cleaning chamber 5 and slide along the inclined surface of the second bolt track 17 within the stainless steel cleaning chamber 5 from front to back. By providing second bolt head limiting grooves 18 on the left and right sides of the second bolt track 17, the bolt heads of the bolts falling into the stainless steel cleaning chamber 5 can slide along the second bolt head limiting grooves 18, and the bolt shanks can slide along the second bolt track 17, thereby achieving orderly conveying of the bolts.

[0047] The system includes a bottom interlayer chamber 21 in the bottom plate, a left interlayer chamber 22 in the left side plate, and a right interlayer chamber 23 in the right side plate. The left and right interlayer chambers 22 and 23 are connected to the bottom interlayer chamber 21. An ultrasonic generator 6 is installed in the bottom interlayer chamber 21, and electromagnetic generators 7 are installed in the left and right interlayer chambers 22 and 23, respectively.

[0048] As the bolts slide and are conveyed from front to back within the stainless steel cleaning chamber 5, the ultrasonic generator 6 and the electromagnetic device 7 remain operational. Because the stainless steel cleaning chamber 5 contains water with added rust remover, the electromagnetic waves generated by the ultrasonic generator 6 during the bolt conveying process allow for ultrasonic rust removal from the bolts within the chamber 5. Meanwhile, rust falling from the bolts into the water is attracted to the side wall of the stainless steel cleaning chamber 5 by the magnetic attraction of the electromagnetic device 7, thus achieving the rust removal and cleaning operation for the bolts.

[0049] After the bolts are derusted, water can be drained through the drain hole at the bottom of the stainless steel cleaning tank 5. Then, the power is turned off to the electromagnetic device 7, and the rust adsorbed on the side wall of the stainless steel cleaning tank 5 will fall into the second bolt head limiting slide groove 18 and the slag collection tank 20. The rust in the second bolt head limiting slide groove 18 can then be collected in the slag collection tank 20 for easy recycling and cleaning, thus preventing environmental pollution.

[0050] In some embodiments of the present invention, the mechanical gripper support 8 includes a left vertical rod 801, a right vertical rod 802, and a horizontal support rod 803. The two ends of the horizontal support rod 803 are respectively connected to the upper ends of the left vertical rod 801 and the upper ends of the right vertical rod 802. The horizontal support rod 803 is located above the rear side plate of the stainless steel cleaning tank 5, and the mechanical gripper mechanism 9 is mounted on the horizontal support rod 803.

[0051] The mechanical gripper mechanism 9 includes a hydraulic telescopic arm 901, a mounting block 902, a drive motor 903, and multiple mechanical grippers 904. The hydraulic telescopic arm 901 extends vertically, with its fixed end connected to a horizontal support rod 803. The bottom front side of the telescopic end of the hydraulic telescopic arm 901 is connected to the mounting block 902. A limiting groove 501 is provided on the inner wall of the rear panel of the stainless steel cleaning tank 5, which slides with the telescopic end of the hydraulic telescopic arm 901, allowing the mounting block 902 to slide up and down along the inner side of the rear panel. The drive motor 903 is mounted on the mounting block 902 on the side facing away from the telescopic end of the hydraulic telescopic arm 901. The drive motor 903 is fixedly connected to one end of a drive shaft 905, which extends horizontally. The other end of the drive shaft 905 is rotatably connected to a bushing, which is fixedly connected to the mounting block 902. One end of each mechanical claw 904 is fixedly connected to the drive shaft 905, and the other end of each mechanical claw 904 forms an arc-shaped gripping part for gripping bolts. The top of the rear side plate corresponds to the front inlet of the drying and oiling roller channel. The mounting block 902 can be moved up and down by the hydraulic telescopic arm 901, and the drive shaft 905 can be rotated by the drive motor 903, which in turn drives each mechanical claw 904 to rotate.

[0052] When a bolt needs to be gripped, the telescopic end of the hydraulic telescopic arm 901 is controlled to move downward so that the mechanical claw 904 can contact the bolt. Then, the mechanical claw 904 is controlled by the drive motor 903 to perform the bolt gripping operation, so that the end of the mechanical claw 904 abuts against the rear side plate, thereby confining the bolt between the mechanical claw 904 and the rear side plate. Then, the telescopic end of the hydraulic telescopic arm 901 is controlled to move upward, thereby conveying the bolt upward until the mechanical claw 904 brings the bolt to the top of the rear side plate. Then, the mechanical claw 904 is controlled by the drive motor 903 to push backward, thereby sending the bolt into the front inlet of the drying and oiling roller channel.

[0053] In some embodiments of the present invention, the upper oiling roller assembly 12 includes a plurality of upper oiling rollers arranged in a horizontal direction, and the lower oiling roller assembly 13 includes a plurality of lower oiling rollers arranged in a horizontal direction. Each upper oiling roller and each lower oiling roller is driven by a motor to rotate, thereby realizing the conveying of bolts.

[0054] In some embodiments of the present invention, the drying lamp includes a plurality of upper drying lamps 24 and a plurality of lower drying lamps 25. Each upper drying lamp 24 is respectively disposed above the front section of the upper oiling roller assembly 12, and each lower drying lamp 25 is respectively disposed below the front section of the lower oiling roller assembly 13. When the bolt is conveyed through the drying and oiling roller channel between the upper oiling roller assembly 12 and the lower oiling roller assembly 13, the bolt can be thoroughly dried by the action of the upper drying lamps 24 and the lower drying lamps 25, thereby accelerating the drying speed of the bolt.

[0055] In some embodiments of the present invention, multiple induction-type oil spraying devices 11 are provided, and the multiple induction-type oil spraying devices 11 are arranged sequentially along the length direction of the upper oiling roller assembly 12, and the multiple induction-type oil spraying devices 11 are respectively installed above the rear section of the upper oiling roller assembly 12. By providing multiple induction-type oil spraying devices 11, oil can be evenly applied to the dried bolts to achieve oiling maintenance of the bolts.

[0056] The working process of the bolt rust removal device according to an embodiment of the present invention is as follows:

[0057] After the user puts the rusty bolts into the bolt feeding box 500, the bolts slide down the first bolt track 15 of the bolt feeding box 500 in an orderly manner and enter the roller group rust removal device 100 through the arc track 600.

[0058] When the bolt enters the rust removal roller channel from the front end of the roller assembly rust removal device 100, the induction spray device 2 senses the bolt and sprays out rust removal liquid. The bolt rotates forward under the action of the upper rust removal roller assembly 3 and the lower rust removal roller assembly 4 with steel wire, so that the bolt is covered with rust removal agent. Under the rolling, squeezing and rotating action of the upper rust removal roller assembly 3 and the lower rust removal roller assembly 4 with steel wire, most of the rust on the bolt is removed, thus achieving the initial rust removal of the bolt.

[0059] After initial rust removal, the bolts fall into the stainless steel cleaning tank 5 and slide along the second bolt track 17 from front to back. During the bolt sliding process, the ultrasonic generator 6 generates ultrasonic waves, which transmit energy through water, thoroughly removing any remaining rust from the bolts. The rust in the water is attracted to the inner wall of the stainless steel cleaning tank 5 by the magnetic force generated by the electromagnetic device 7. Once the water in the stainless steel cleaning tank 5 is drained, the electromagnetic device 7 stops generating magnetic force, and the rust falls into the second bolt head limiting groove 18. Because the second bolt head limiting groove 18 is inclined, it facilitates the rust to enter the slag collection tank 20 for collection. After being thoroughly rust-removed and cleaned by the rust removal and cleaning device 200, the bolts slide to the horizontal gripping area 19.

[0060] The mechanical claw transport device 300 lowers the mechanical claw 904 via the hydraulic telescopic arm 901 and controls the mechanical claw 904 to grip the bolt via the drive motor 903. The ends of each mechanical claw 904 contact the inner wall of the rear side plate of the stainless steel cleaning box 5 to grip the bolt. Then, the mechanical claw 904 moves upward via the hydraulic telescopic arm 901, thereby transporting the bolt to the drying and oiling roller channel of the drying and oiling device 400.

[0061] The bolt enters the drying and oiling roller channel, where it is rotated and conveyed forward by the action of the upper oiling roller group 12 and the lower oiling roller group 13. During the conveying process, the upper drying lamp 24 and the lower drying lamp 25 rapidly evaporate the moisture on the bolt. The bolt then continues to roll forward in the drying and oiling roller channel, entering the oiling area. When the induction oil spraying device 11 senses the bolt, it sprays oil to coat the bolt surface, isolating the bolt from external oxygen and preventing further oxidation, thus completing the bolt maintenance process.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
