Description

Technical Field

[0001] The invention relates to the technical field of metal surface processing, in particular to oil removal and impurity removal equipment for metal surface processing. Background Art

[0002] In the traditional field of metal surface treatment, degreasing and impurity removal is a basic and critical process. At present, the degreasing and impurity removal treatment of metal sheets is roughly divided into two categories: chemical treatment and physical treatment. Chemical treatment usually involves immersing the metal sheet in a solution containing specific chemical components, removing the oil on the surface through chemical reactions, and removing impurities by immersion. Although this method can remove oil and impurities to a certain extent, there are several significant problems: first, chemical treatment requires immersion to achieve the desired degreasing and impurity removal effect, which limits the efficiency of the operation; second, the number of metal sheets processed each time is fixed and cannot be flexibly adjusted to meet the production needs of different scales.

[0003] On the other hand, physical treatment mainly refers to mechanical brushing and other methods. These methods directly remove oil and impurities from the metal surface through physical force. However, it is difficult to achieve fast assembly line operation during mechanical grinding, resulting in overall low efficiency. At the same time, due to the different technical levels and working conditions of operators, product quality may fluctuate and consistency cannot be guaranteed.

[0004] In summary, the existing methods for removing oil and impurities from metal sheets have their own limitations and cannot meet the high requirements of modern production for efficiency, environmental protection and product quality. Therefore, the development of a new type of equipment for removing oil and impurities from metal surface treatment, which can not only improve operating efficiency, but also ensure the stability of product quality and reduce environmental pollution, has become an urgent problem to be solved in the industry. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an oil removal and impurity removal device for metal surface treatment, which solves the problem of low efficiency in the existing metal plate oil removal and impurity removal process.

[0016] Preferably, the rotation of each of the processing components includes rotation in a first direction around the central axis of the swivel seat and / or rotation in a second direction around the central axis of the first swivel.

[0017] Preferably, the processing component comprises:

[0018] The lower rotating body is rotatably arranged on the rotating body seat through a third rotating member, a cavity is formed inside the lower rotating body, and the cavity is filled with a first medium; a second nozzle is arranged on the bottom surface of the lower rotating body, and a brush is fixed on the bottom of the lower rotating body; wherein the first medium inside the lower rotating body is sprayed out by the second nozzle to act on the brush;

[0019] A cylindrical member is connected through the center of the lower rotating body, and the cylindrical member is filled with a second medium; a plurality of first nozzles are distributed circumferentially on the cylindrical member;

[0020] When the second medium is ejected from the first nozzle, a driving force is generated to rotate the cylindrical member and the lower rotating body on the rotating body seat, and when the second medium is ejected, it acts on the brush and causes the first medium to splash outward.

[0021] Preferably, an angle α is formed between the first nozzle and the cylindrical member.

[0022] Preferably, a shield is fixed on the lower rotating body, and the shield covers at least a portion of the length of the brush.

[0023] Preferably, the first rotating body is rotatably connected to the end cover via a second rotating member, and the first rotating body comprises:

[0024] An upper rotating body, wherein the upper rotating body and the end cover form a cavity when closed;

[0025] The partition is annular and is arranged in the cavity to divide the inside and outside of the cavity into a first cavity and a second cavity.

The second branch pipe passes through the rotating body seat and is connected to the cylindrical member through the fourth rotating member.

[0028] Preferably, an air pump and a liquid supply pump connected to the first medium delivery pipeline and the second medium delivery pipeline are arranged on the box body.

[0031] Beneficial effects of the present invention: By using the oil removal and impurity removal equipment for metal surface treatment provided by the present invention, the following technical effects are achieved compared with the prior art:

[0032] First, the equipment uses two sets of processing mechanisms to contact the upper and lower surfaces of the metal plate respectively, so as to simultaneously process the upper and lower surfaces of the metal plate while it is being transported on the conveyor rollers, and complete the degreasing and impurity removal of the metal plate in one go. This design significantly improves the operating efficiency because it is no longer necessary to process each side of the metal plate in steps, thereby shortening the overall processing time.

[0033] The driving force generated by the first medium ejected from the first nozzle causes the cylindrical member and the lower swivel to rotate on the swivel seat. This mechanical action not only reduces the need for manual operation, but also improves the degree of automation of the treatment process. At the same time, the first medium acts on the brush when it is ejected, and causes the second medium to sputter outward, increasing the diffusion area of ​​the second medium, thereby increasing the area for oil and impurity removal. This dual action mechanism ensures that the treatment agent can cover the metal surface more evenly and comprehensively, improving the oil and impurity removal effect.

[0034] When the lower rotor spins, the treatment agent contacts the brush and then splashes outward, contacts the metal plate surface, and enhances the degreasing and impurity removal effect through the brush during the spin. This design allows the treatment agent to penetrate deeper into the tiny gaps on the metal surface, thereby improving the thoroughness of degreasing and impurity removal. At the same time, the rotation of the upper rotor drives the spinning lower rotor and the brush to rotate over a large range around the axis of the upper rotor, so that the treatment agent and the brush can degreasing and impurity removal from the metal surface in a double rotation state. This composite motion mode further expands the treatment range and ensures that even large areas of metal plates can be treated evenly.

[0035] Finally, the high-pressure gas that rotates the lower rotating body can help the treatment agent to sputter to the outside. This design further increases the degreasing and impurity removal area and improves the degreasing and impurity removal effect. Through this efficient degreasing and impurity removal mechanism, the equipment of the present invention can complete the degreasing and impurity removal of large-area metal plates in a short time, significantly improving production efficiency.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the implementation scheme.

[0044] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0045] Reference Figure 1-5 An oil removal and impurity removal apparatus for metal surface treatment according to the present embodiment will be described.

[0046] The oil removal and impurity removal equipment comprises a box 1, a fixture frame 5 and a processing mechanism 4. The box 1 is a long strip trough box with an open top; a plurality of conveying rollers 2 are arranged in the extension direction of the inner top of the box 1, and a metal plate is conveyed on the conveying rollers 2. The conveying rollers 2 are horizontally mounted at the top opening of the box 1, so that the metal plate can be conveyed from one end to the other end through the conveying rollers 2.

[0047] In one embodiment, there are two groups of conveying rollers 2, which are respectively arranged on the left and right sides of the box body 1, and a gap 3 is formed between the two groups of conveying rollers 2, and the processing mechanism 4 is arranged at the gap 3. The tooling frame 5 is fixed to the top of the inner side of the box body 1 and is located at the gap 3, so that the processing mechanism 4 can remove oil and impurities from the metal plate in the conveying state.

[0048] In this embodiment, there are two groups of processing mechanisms 4, which are arranged on the tooling frame 5 opposite to each other up and down, and the two groups of processing mechanisms 4 contact the upper and lower surfaces of the metal plate respectively, so as to simultaneously process the upper and lower surfaces of the metal plate and complete the degreasing and impurity removal of the metal plate at one time.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, the processing mechanism 4 includes an end cover 44, a first rotating body, a plurality of brackets 413 and a plurality of second rotating bodies. The end cover 44 is fixedly connected to the tooling frame 5, and the first rotating body is rotatably arranged on the end cover 44; a plurality of brackets 413 are fixedly connected to the first rotating body and are circumferentially distributed along the axis of the first rotating body; a plurality of second rotating bodies are arranged on the plurality of brackets 413 in a one-to-one correspondence, and the brackets 413 drive the second rotating bodies to rotate in the first direction around the axis of the first rotating body, and each second rotating body rotates in the second direction relative to the corresponding bracket 413.

[0050] like Figure 4As shown, a motor 41 is fixed on the end cover 44, and the output end of the motor 41 passes through the end cover 44 and is fixedly connected to the upper rotating body 42. The first rotating body is rotatably connected to the end cover 44 through the second rotating member 48. The first rotating body includes the upper rotating body 42 and the partition 49. The upper rotating body 42 and the end cover 44 are closed to form a cavity. The partition 49 is annular and is arranged in the cavity, and separates the inside and outside of the cavity into a first cavity 46 and a second cavity 410. The bottom end of the partition 49 is fixedly connected to the upper rotating body 42, and the top end is rotatably connected to the end cover 44 through the first rotating member 45. With the above-mentioned design, the motor 41 drives the upper rotating body 42 to rotate on the end cover 44, and when the upper rotating body 42 rotates, it carries the partition 49 to rotate on the end cover 44 together, so that the partition 49 can separate the cavity into two sealed first cavities 46 and second cavities 410.

[0051] Furthermore, the end cover 44 is provided with a first medium delivery pipeline 8 and a second medium delivery pipeline 9. In a preferred embodiment, the first medium delivery pipeline 8 delivers high-pressure gas, and the second medium delivery pipeline 9 delivers treatment agent. The box body 1 is provided with an air pump 7 and a liquid supply pump 6 connected to the first medium delivery pipeline 8 and the second medium delivery pipeline 9. The liquid suction end of the liquid supply pump 6 is connected to the inside of the box body 1 to suck the treatment agent received in the box body 1; the liquid suction end of the liquid supply pump 6 is connected to the outside of the box body 1 and / or connected to the treatment agent supply tank. The first medium delivery pipeline 8 and the second medium delivery pipeline 9 are respectively connected to the first cavity 46 and the second cavity 410, and the high-pressure gas and the treatment agent are pumped into the first cavity 46 and the second cavity 410; the bottom of the upper rotating body 42 is provided with a first branch pipeline 411 and a second branch pipeline 412 connected to the first cavity 46 and the second cavity 410, the other end of the first branch pipeline 411 passes through the rotating body seat 414 and is connected to the cavity 43, and the second branch pipeline 412 passes through the rotating body seat 414 and is connected to the cylindrical member 417 through the fourth rotating member 421; the high-pressure gas in the first cavity 46 enters into the cylindrical member 417 through the second branch pipeline 412, and the treatment agent in the second cavity 410 enters into the cavity 43 through the first branch pipeline 411.

[0052] like Figure 4 As shown, the second swivel includes a swivel seat 414 and a processing assembly, and the swivel seat 414 is fixedly connected to the bracket 413, so that when the upper swivel 42 rotates, the swivel seat 414 and the processing assembly are driven by the bracket 413 to rotate around the axis of the upper swivel 42, so that the processing assembly can remove oil and impurities from the surface of the metal plate in the rotating state. The processing assembly is rotatably arranged on the swivel seat 414, and the rotation of each processing assembly includes rotation in a first direction around the central axis of the swivel seat 414 and / or rotation in a second direction around the central axis of the first swivel, so that the processing assembly can remove oil and impurities from the surface of the metal plate while rotating around the axis of the upper swivel 42, and can also process the surface of the metal plate in the self-rotating state.

[0053] In one embodiment, the processing assembly includes a lower rotating body 415 and a cylindrical member 417. The lower rotating body 415 is rotatably arranged on the rotating body seat 414 through the third rotating member 420, and a cavity 43 is formed inside the lower rotating body 415, and the cavity 43 is filled with a second medium by the first branch pipe 411; a second nozzle 419 is arranged on the bottom surface of the lower rotating body 415, and a brush 416 is fixed to the bottom of the lower rotating body 415. The second medium in the cavity 43 is sprayed out by the second nozzle 419 to act on the brush 416, and the second medium is irregularly sputtered around when impacting the brush 416; the cylindrical member 417 is connected through the center of the lower rotating body 415, and the cylindrical member 417 is connected to the bottom of the lower rotating body 415. The second branch pipe 412 is filled with the first medium, which is a high-pressure gas; a plurality of first nozzles 418 are distributed circumferentially on the cylindrical member 417; an angle α is formed between the first nozzle 418 and the cylindrical member 417, and the angle α is 60°; with this arrangement, when the first medium is ejected from the first nozzle 418, a driving force is generated, so that the cylindrical member 417 and the lower rotating body 415 rotate on the rotating body seat 414, and when the first medium is ejected, it acts on the brush 416 and causes the second medium to splash outward, thereby increasing the diffusion area of ​​the second medium and improving the oil and impurity removal area. The treatment agent is splashed outwardly onto the surface of the metal plate after contacting the brush 416 when the lower rotor 415 is spinning, and the brush 416 is used to enhance the degreasing and impurity removal effect during spinning. Meanwhile, the rotation of the upper rotor 42 drives the spinning lower rotor 415 and the brush 416 to rotate over a large range around the axis of the upper rotor 42, so that the treatment agent and the brush 416 can remove oil and impurities from the metal surface in a double rotation state. Meanwhile, the high-pressure gas generated by the rotation of the lower rotor 415 can help the treatment agent to splash outward, thereby further enhancing the degreasing and impurity removal area and improving the degreasing and impurity removal effect.

[0054] A shield 47 is fixed on the lower rotating body 415, and the shield 47 covers at least a portion of the length of the brush 416. The design of the shield 47 can prevent the first medium from splashing to the outside, ensuring that the first medium acts on the surface of the metal plate for sputtering.

[0055] Working principle: The metal plate is placed on the conveying roller 2 and transported from one end to the other end. During the transportation process, it enters the inner side of the tooling frame 5, and the upper and lower surfaces contact the processing mechanism 4.

[0056] The liquid supply pump 6 draws the treatment agent and pumps it into the second cavity 410 through the second medium delivery pipe 9. The second medium is filled into the cavity 43 through the first branch pipe 411, and then sprayed out through the second nozzle 419 to act on the brush 416. When impacting the brush 416, the second medium sputters irregularly in all directions, so that the second medium directly acts on the surface of the metal plate to remove oil and impurities from the metal plate.

[0057] The air pump 7 generates high-pressure gas which is delivered to the first cavity 46 through the first medium delivery pipe 8, and then enters the cylindrical member 417 through the second branch pipe 412. When the first medium is ejected from the first nozzle 418, a driving force is generated to drive the cylindrical member 417 to drive the lower rotating body 415 to rotate on the rotating body seat 415, and the cylindrical member 417 rotates on the second branch pipe 412 through the fourth rotating member 421. The first medium is ejected through the first nozzle 418, and when the lower rotating body 415 rotates in the first direction around the central axis of the rotating body seat 414, it drives the brush 416 to contact the surface of the metal plate. In addition, the ejected high-pressure gas acts on the brush 416 and causes the treatment agent to sputter outward, thereby increasing the diffusion area of ​​the treatment agent and improving the oil and impurity removal area.

[0058] The motor 41 drives the upper rotating body 42 to rotate on the end cover 44, and the upper rotating body 42 rotates with the partition plate 49 to rotate on the end cover 44. When the upper rotating body 42 rotates, the bracket 413 drives the rotating body seat 414 and the lower rotating body 415 to rotate in the second direction around the central axis of the upper rotating body 42.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
