Description

Technical Field

[0001] This utility model relates to the technical field of shot blasting equipment, and in particular to an adsorption-type rust removal device for plate surfaces. Background Technology

[0002] As we all know, rust is likely to occur on sheet metal or boxes during long-term storage, and rust removal is often required. The common method is to use sandpaper or other polishing tools for sanding. However, in factories, shot blasting is often used to treat sheet metal or boxes in order to improve efficiency.

[0003] For example, Chinese utility model patent CN209887402U discloses a vertical shot blasting machine, including a traveling mechanism and a shot blasting mechanism. The traveling mechanism is a magnetic traveling mechanism, and the shot blasting mechanism includes a shot blaster, a reflective channel, and a separator. The shot blaster includes a shot inlet pipe and a shot outlet pipe, the separator includes a feed inlet and a lower discharge outlet, and the reflective channel is a V-shaped channel. The shot inlet pipe of the shot blaster is connected to the discharge outlet of the separator, and the inlet and outlet of the reflective channel are connected to the shot outlet pipe and the feed inlet, respectively. It can not only adhere to the surface of steel plates but also smoothly pass over weld seams on the steel plate surface, moving unimpeded. Through the combination of the shot blaster and the separator, the steel shot can be recycled, thus eliminating the need for an external sand supply device. This not only reduces equipment costs and size but also allows the shot blasting machine to have more flexible operating modes, replacing manual labor in various shot blasting tasks.

[0004] However, the device's walking mechanism uses a tracked magnetic adsorption method to achieve adsorption with the surface to be shot blasted, which means that the walking mechanism can only move in a straight line. Manual intervention is required during turning and other processes, resulting in poor walking flexibility. It is also bulky, occupies a lot of space, and is not conducive to storage and transportation. The shot blasting operation area is limited during parking. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adsorption-type rust removal device for plate surfaces that offers greater flexibility in movement, eliminates the need for manual intervention during turning, occupies less storage space, is easy to store, and increases the shot blasting area during stationary operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adsorption-type rust removal device for plate surfaces, comprising a frame, a shot blasting mechanism mounted on the frame, and at least four sets of folding adsorption-type traveling arms. Each folding adsorption-type traveling arm includes a rotating arm hinged to the frame, a bending arm hinged to the rotating arm, and a support arm hinged to the bending arm. A first servo motor is mounted on the frame to provide power for the rotation of the rotating arm. A second servo motor is mounted on the rotating arm to provide power for the rotation of the bending arm. A third servo motor is mounted on the bending arm to provide power for the rotation of the support arm. A pneumatic suction cup is mounted on the support arm. Furthermore, the pneumatic suction cup is connected to an external negative pressure air source.

[0007] Preferably, the shot blasting mechanism includes a barrel fixedly mounted on a frame, a mounting frame mounted at the bottom of the frame, a conical shot blasting rotor rotatably mounted at the bottom of the mounting frame, and a suction fan communicating with the inside of the barrel. The mounting frame is equipped with a drive motor that provides power for the rotation of the conical shot blasting rotor. The discharge end of the suction fan is equipped with a feeding pipe, and the discharge end of the feeding pipe faces the conical slope of the conical shot blasting rotor.

[0008] Preferably, there are multiple suction fans and multiple feeding pipes, with the multiple suction fans evenly distributed around the circumference of the material cylinder, and the discharge ends of the multiple feeding pipes evenly distributed around the circumference of the conical shot blasting rotor.

[0009] Preferably, the mounting bracket is slidably mounted on the frame, and the frame is equipped with a telescopic cylinder that provides power for the sliding of the mounting bracket; further, there are at least two sets of telescopic cylinders, and the frame is provided with a telescopic guide rod that guides the sliding of the mounting bracket; the feeding pipe is provided with a corrugated telescopic pipe section.

[0010] Preferably, the mounting bracket is rotatably mounted with grinding brushes evenly distributed around the conical shot blasting rotor, the output end of the drive motor is fixedly mounted with a main gear, and the mounting bracket is rotatably mounted with a driven gear integrally connected to the corresponding grinding brush, and the main gear meshes with the driven gear.

[0011] Preferably, the mounting bracket is equipped with a rubber enclosure.

[0012] Preferably, the feed pipe passes between two adjacent brushes.

[0013] Compared with the prior art, this utility model provides an adsorption-type rust removal device for plate surfaces, which has the following beneficial effects: This adsorption-type rust removal device can achieve multi-directional arbitrary drive adjustment of the shot blasting robot through the folding adsorption walking arm. In the non-operation state, the support arm and bending arm are folded together and placed at the rotating arm, while the rotating arm rotates inward towards the frame. The folding adsorption walking mechanism is completely stored, which effectively reduces the space occupied by the equipment, makes the movement more flexible, and eliminates the need for manual intervention in processes such as turning. It occupies little storage space and is easy to store. When each starting suction cup is fixedly adsorbed on the surface to be shot blasted, the shot blasting mechanism can be moved forward, backward, left, and right by coordinating and adjusting the bending extension length of each bending adsorption walking arm, thereby increasing the shot blasting area when stationary.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model discloses an adsorption-type rust removal device for plate surfaces, comprising a frame 1, a shot blasting mechanism mounted on the frame 1, and at least four sets of folding adsorption-type walking arms. Each folding adsorption-type walking arm includes a rotating arm 2 hinged to the frame 1, a bending arm 3 hinged to the rotating arm 2, and a support arm 4 hinged to the bending arm 3. A first servo motor 5 is mounted on the frame 1 to provide power for the rotation of the rotating arm 2; a second servo motor 6 is mounted on the rotating arm 2 to provide power for the rotation of the bending arm 3; a third servo motor 7 is mounted on the bending arm 3 to provide power for the rotation of the support arm 4; and a pneumatic suction cup 8 is mounted on the support arm 4. Furthermore, the pneumatic suction cup 8 is connected to an external negative pressure air source. The first servo motor 5, the second servo motor 6, and the third servo motor 7 can respectively drive the rotating arm 2, the bending arm 3, and the support arm 4 to rotate in the desired direction. The four sets of folding walking arms can simulate the crawling motion of multi-armed crawling animals such as spiders, significantly improving mobility.

[0021] A rubber enclosure 19 is installed on the mounting frame 10. The rubber enclosure 19 can reduce the abrasive and dust generated during the shot blasting operation from flying around. When the shot blasting robot completes a reciprocating operation or a certain amount of abrasive is accumulated, the abrasive accumulated in the rubber enclosure 19 can be collected and put back into the material cylinder 9 for reuse.

[0022] Specifically, the shot blasting mechanism includes a barrel 9 fixedly mounted on a frame 1, a mounting frame 10 mounted at the bottom of the frame 1, a conical shot blasting rotor 11 rotatably mounted at the bottom of the mounting frame 10, and a suction fan 12 communicating with the inside of the barrel 9. A drive motor 13 is mounted on the mounting frame 10 to provide power for the rotation of the conical shot blasting rotor 11. A feeding pipe 14 is installed at the discharge end of the suction fan 12, with the discharge end of the feeding pipe 14 facing the conical slope of the conical shot blasting rotor 11. The suction fan 12 pressurizes the abrasive material inside the barrel 9 and ejects it through the feeding pipe 14. The abrasive material contacts the conical slope of the high-speed rotating conical shot blasting rotor 11. Under the action of the impact reaction force and the centrifugal force of the conical shot blasting rotor 11, the abrasive material moves along the axial direction of the conical shot blasting rotor 11 away from the center of the conical shot blasting rotor 11 (please refer to...). Figure 3 (The arrow in the image indicates the direction of the shot blasting). The abrasive forms a conical working surface for shot blasting the surface to be treated. Compared with the cylindrical shot blasting rotor, the conical shot blasting rotor 11 can adjust the direction of the force exerted by the abrasive on the shot blasting surface to increase the contact area between the abrasive and the surface to be treated, thereby improving the shot blasting efficiency of the surface to be treated.

[0023] Specifically, there are multiple suction fans 12 and multiple feeding pipes 14. The multiple suction fans 12 are evenly distributed around the material cylinder 9, and the discharge ends of the multiple feeding pipes 14 are evenly distributed around the conical shot blasting rotor 11. By supplying abrasive to the conical shot blasting rotor 11 through multiple suction fans 12 and multiple feeding pipes 14, the uniformity of abrasive distribution around the conical shot blasting rotor 11 can be improved, so as to ensure that the abrasive is uniformly shot blasted on the surface to be treated.

[0024] The mounting frame 10 is slidably mounted on the frame 1, and the frame 1 is equipped with a telescopic cylinder 15 that provides power for the sliding of the mounting frame 10; furthermore, there are at least two sets of telescopic cylinders 15, and the frame 1 is provided with a telescopic guide rod that guides the sliding of the mounting frame 10; the feeding pipe 14 is provided with a corrugated telescopic pipe section; by activating the telescopic cylinder 15, the distance between the mounting frame 10 and the frame 1 can be adjusted, thereby adjusting the distance between the conical shot blasting rotor 11 and the surface to be shot blasted, so as to adaptively adjust the distance at which the abrasive is thrown by the conical shot blasting rotor 11, and at the same time avoid the conical shot blasting rotor 11 from contacting the surface to be treated during the movement of the shot blasting robot, so as to prevent interference with the normal movement of the shot blasting robot.

[0025] The mounting frame 10 is rotatably mounted with circumferentially distributed grinding brushes 16 around the conical shot blasting rotor 11. The output end of the drive motor 13 is fixedly mounted with a main gear 17. The mounting frame 10 is rotatably mounted with a driven gear 18 integrally connected to the corresponding grinding brush 16. The main gear 17 and the driven gear 18 mesh. The drive motor 13 drives the main gear 17 to rotate. After being transmitted by each driven gear 18, each grinding brush 16 rotates synchronously. The grinding brush 16 drives the abrasive material that has come into contact with the shot blasting surface to rotate again. Under the action of the grinding brush 16 and the abrasive material, the surface to be treated is subjected to friction rust removal treatment, so as to further improve the rust removal effect of the shot blasting surface.

[0026] The feed pipe 14 passes between two adjacent brushes 16; this arrangement prevents the feed pipe 14 from interfering with the rotation of the brushes 16.

[0027] In use, the pneumatic suction cup 8 is connected to an external negative pressure air source. The pneumatic suction cup 8 is attached to the surface to be treated. The folding suction-type walking arm drives the frame 1 to move. The suction fan 12 pressurizes the abrasive in the material cylinder 9 and sprays it out through the feeding pipe 14. The abrasive comes into contact with the conical slope of the high-speed rotating conical shot blasting rotor 11 and acts on the surface to be treated. Then the grinding brush 16 drives the abrasive to rotate again, and the shot blasting surface is shot blasted.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 therein. Such 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 this application.
