[0018] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] The steel plate surface grinding and rust removal device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 7 As shown, the steel plate surface grinding and rust removal device of the embodiment of the present application includes a rust removal box 1, two limit frames 2, two grinding mechanisms 3, a feeding component 4, a pulling component 5 and a dust collection component.

[0021] A discharge port 10 and a discharge port 11 are provided on the rust removal box body 1 , and driving mechanisms 12 are respectively provided on both sides of the rust removal box.

[0022] In the embodiment of the present application, the driving mechanism 12 is used to drive the corresponding limiting frame 2 to slide horizontally in the rust removal box 1.

[0023] The two limiting frames 2 are elastically slidably disposed in the rust removal box 1 , and the two limiting frames 2 are respectively abutted by corresponding driving mechanisms 12 .

[0024] It should be noted that the elastic sliding connection between the limit frame 2 and the rust removal box 1 described in this embodiment means that: an elastic abutment 22 is provided on the limit frame 2 (the elastic abutment 22 is a common elastic component on the market, and the specific structure is not described here), and one end of the elastic abutment 22 is provided on the rust removal box 1. Through the setting of the elastic abutment 22, after the driving mechanism 12 drives the limit frame 2 to move horizontally, the limit frame 2 returns to its original state under the abutment of the elastic abutment 22, thereby realizing the reciprocating drive control of the limit frame 2 by the driving mechanism 12.

[0025] In an embodiment of the present application, the limit frame 2 is used to limit the position of the corrugated steel plate, and when the driving mechanism 12 drives the limit frame 2 to move back and forth, the limit frame 2 can drive the corrugated steel plate to move back and forth, so that the corrugated steel plate can move back and forth between the two grinding mechanisms 3 and be reciprocated by the grinding mechanism 3, thereby improving the grinding quality of the corrugated steel plate.

[0026] It should be noted that the rust removal box 1 described in this embodiment has two first auxiliary material ports 13, one located on either side of the rust removal box 1. One first auxiliary material port 13 is connected to the discharge port 10, and the other first auxiliary material port 13 is connected to the discharge port 11. In addition, the limiting frame 2 has two second auxiliary material ports 21, which are connected to the corresponding first auxiliary material ports 13. The provision of the first auxiliary material ports 13 and the second auxiliary material ports 21 facilitates the loading and unloading of corrugated steel plates.

[0027] The two grinding mechanisms 3 are respectively slidably arranged on the rust removal box 1 and are symmetrically arranged. The two grinding mechanisms 3 are respectively arranged up and down and are located between the two limiting frames 2.

[0028] It should be noted that the grinding mechanism 3 described in this example is slidably arranged on the rust removal box 1, and the sliding direction is vertical sliding, so as to facilitate the upward and downward movement control of the grinding mechanism 3 by the corrugated shape of the corrugated steel plate.

[0029] It can be understood that, by arranging the two grinding mechanisms 3 symmetrically in the upper and lower directions, the device can grind both sides of the corrugated steel plate simultaneously, thereby improving the grinding efficiency of the corrugated steel plate.

[0030] A plurality of abutment and limiting mechanisms 34 are rotatably provided on the grinding mechanism 3 , and the plurality of abutment and limiting mechanisms 34 in the two grinding mechanisms 3 are symmetrically arranged and correspondingly abut against the upper and lower sides of the corrugated steel plate.

[0031] In the embodiment of the present application, the abutment and limiting mechanism 34 is used to abut the surface of the corrugated steel plate, so that the abutment and limiting mechanism 34 can move with the corrugated steel plate and drive the grinding mechanism 3 to move on the rust removal box 1, so that the grinding mechanism 3 can move up and down and grind according to the waveform of the steel plate, thereby realizing the grinding of the corrugated steel plate.

[0032] The feeding assembly 4 is slidably arranged on the corresponding limiting frame 2 .

[0033] In the embodiment of the present application, the feeding assembly 4 is used to push the corrugated steel plate to move within the limiting frame 2, and push the corrugated steel plate between the two grinding mechanisms 3, thereby ensuring the grinding effect of the corrugated steel plate.

[0034] The material pulling assembly 5 is slidably arranged on the corresponding limiting frame 2 .

[0035] In the embodiment of the present application, the pulling assembly 5 is used to pull out the polished corrugated steel plate, and can pull the unpolished corrugated steel plate to continue to move between the two polishing mechanisms 3, thereby ensuring the polishing effect of the corrugated steel plate.

[0036] The dust collection assembly is arranged on the rust removal box 1 .

[0037] In the embodiment of the present application, the dust collection component is used to absorb the waste chips or dust produced by the grinding mechanism 3, thereby ensuring the factory environment.

[0038] Specifically, during the actual operation, the relevant staff places the corrugated steel plate at the discharge port 10, and the controller (not shown in the figure) controls the feeding assembly 4 to work. The feeding assembly 4 pushes the corrugated steel plate to move in the limit frame 2 and gradually moves between the two grinding mechanisms 3. When it moves between the two grinding mechanisms 3, the corrugated steel plate is inserted between the upper and lower symmetrical abutment limit mechanisms 34. At this time, the two grinding mechanisms 3 grind the upper and lower surfaces of the corrugated steel plate respectively.

[0039] The corrugated steel plate continues to move toward the grinding mechanism 3, and the waveform on the steel plate abuts against the abutment limit mechanism 34, so that the abutment limit mechanism 34 drives the corresponding grinding mechanism 3 to slide up and down on the rust removal box 1, thereby ensuring that the grinding mechanism 3 moves up and down to the position of the corrugated steel plate to be ground, thereby realizing the grinding of the corrugated steel plate, and in the process of grinding, the dust collection component works to absorb waste chips and dust. After one end of the corrugated steel plate is ground, the controller controls the pulling component 5 to work, and the pulling component 5 gradually pulls out the grounded corrugated steel plate. After pulling it out, the relevant staff removes the corrugated steel plate to complete the grinding of the corrugated steel plate.

[0040] In one embodiment of the present application, Figure 2 and Figure 6 As shown, the grinding mechanism 3 includes two sliding plates 31 , a grinding motor 30 , a rotating shaft 32 and a plurality of flap wheels 33 .

[0041] Among them, two sliding plates 31 are slidably set on the rust removal box 1, the grinding motor 30 is set on the corresponding sliding plate 31, the ends of the rotating shaft 32 are respectively rotatably set on the corresponding sliding plates 31, the output shaft of the grinding motor 30 is connected to the rotating shaft 32, one end of multiple abutment limit mechanisms 34 is respectively rotatably set on the rotating shaft 32, and multiple flap wheels 33 are respectively set on the rotating shaft 32.

[0042] It should be noted that the flap wheel 33 described in this embodiment is a common grinding component on the market, which can perform soft grinding on the corrugated steel plate, thereby avoiding hard contact with the corrugated steel plate and damaging the corrugated steel plate.

[0043] In one embodiment of the present application, Figure 2 and Figure 7 As shown, the abutment and limiting mechanism 34 includes a limiting base 340 , a limiting block 341 , a fixing plate 342 and an abutment wheel 343 .

[0044] The limiting base 340 is provided on the rust removal box 1 , the limiting block 341 is provided on the limiting base 340 , the fixing plate 342 is slidably provided on the limiting block 341 , and the abutting wheel 343 is rotatably provided on the fixing plate 342 .

[0045] It should be noted that the limiting blocks 341 described in this embodiment can be provided in two numbers, or the limiting blocks 341 can be provided in a square shape, so as to prevent the fixing plate 342 from rotating on the limiting blocks 341 .

[0046] It should be noted that the abutment wheel 343 described in this embodiment is provided with an anti-wear layer, so as to avoid friction damage to the corrugated steel plate when the corrugated steel plate moves left and right.

[0047] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the driving mechanism 12 includes a reciprocating motor 120 and a cam 121 .

[0048] The reciprocating motor 120 is provided on the rust removal box 1 , the output shaft of the reciprocating motor 120 is connected to the cam 121 , and the cam 121 is in rotational contact with the corresponding limiting frame 2 .

[0049] It can be understood that, by disposing the cam 121 , it cooperates with the elastic abutment member 22 , thereby being able to reciprocate the limiting frame 2 .

[0050] In one embodiment of the present application, Figure 3 As shown, the feeding assembly 4 includes a first electric telescopic rod 40 , a feeding slider 41 and a pushing plate 42 .

[0051] Among them, the first electric telescopic rod 40 is arranged on the corresponding limit frame 2, the extending shaft of the first electric telescopic rod 40 is connected to the feeding slider 41, the feeding slider 41 is slidingly arranged on the corresponding limit frame 2, one end of the feeding slider 41 is slidingly connected to the slide groove 20 opened on the corresponding limit frame 2, and the push plate 42 is arranged on the feeding slider 41 and is located in the corresponding limit frame 2.

[0052] It should be noted that the shape of the pusher plate 42 described in this embodiment fits one end of the corrugated steel plate, thereby facilitating the pushing effect of the corrugated steel plate. In one embodiment of the present application, Figure 2 and Figure 4 As shown, the material pulling assembly 5 includes a second electric telescopic rod 50 , a material pulling slider 51 and an electromagnetic adsorption plate 52 .

[0053] Among them, the second electric telescopic rod 50 is arranged on the corresponding limit frame 2, the extending shaft of the second electric telescopic rod 50 is slidably connected with the pulling slider 51, the pulling slider 51 is slidably arranged on the corresponding limit frame 2, one end of the pulling slider 51 is slidably connected with the slide groove 20 opened on the corresponding limit frame 2, and the electromagnetic adsorption plate 52 is arranged on the pulling slider 51 and is located in the corresponding limit frame 2.

[0054] It should be noted that the electromagnetic adsorption plate 52 described in this embodiment is a common powered adsorption component on the market. It can adsorb corrugated steel plates when powered on and not adsorb corrugated steel plates when powered off. Since it is an existing technology, it will not be described in detail here.

[0055] In one embodiment of the present application, Figure 1 As shown, the dust collection assembly includes a dust collection device and a dust collection pipe 6.

[0056] The dust collection device is provided on the rust removal box 1 , one end of the dust collection pipe 6 is connected to the dust collection device, and the other end of the dust collection pipe 6 is connected to the rust removal box 1 .

[0057] It should be noted that there are multiple dust suction pipes 6 described in this embodiment, and they are respectively arranged at the top and bottom of the rust removal box 1, so as to increase multiple air suction points and improve the dust suction effect of the dust suction component.

[0058] Specifically, during the actual operation, the relevant staff places the corrugated steel plate at the discharge port 10, and the controller (not shown in the figure) controls the first electric telescopic rod 40 to retract, and drives the feeding slider 41 and the pushing plate 42 to slide on the corresponding limit frame 2, and the pushing plate 42 pushes one end of the corrugated steel plate and pushes the corrugated steel plate to move between the two grinding mechanisms 3. When it moves between the two grinding mechanisms 3, the corrugated steel plate is inserted between the upper and lower symmetrical abutment wheels 343, and the controller controls the corresponding grinding motor 30 to rotate, and the grinding motor 30 drives the rotating shaft 32 and the flap wheel 33 to rotate, and the flap wheel 33 rotates to grind the corresponding surface of the corrugated steel plate.

[0059] In addition, the controller controls the corresponding reciprocating motor 120 to rotate and drives the cam 121 to rotate. The cam 121 abuts the corresponding limit frame 2 and moves laterally in the rust removal box 1. With the cooperation of the elastic deformation of the elastic abutment, the corresponding limit frame 2 moves back and forth in the rust removal box 1 and drives the corrugated steel plate to move back and forth, so that the corrugated steel plate moves back and forth at the flap wheel 33, thereby improving the grinding effect of the corrugated steel plate.

[0060] The controller controls the feeding assembly 4 to continue feeding, so that the pushing plate 42 continues to push the corrugated steel plate to move between the two abutment wheels 343, and the waveform on the steel plate continues to abut against the abutment wheel 343, so that the abutment wheel 343 and the fixed plate 342 slide up and down on the limit block 341, and in the process of sliding up and down, because the abutment wheel 343 and the rotating shaft 32 rotate and abut, the abutment wheel 343 drives the rotating shaft 32 to move up and down in real time, and the rotating shaft 32 drives the flap wheel 33 to move following the waveform of the steel plate, thereby grinding and removing rust on the corresponding surface of the corrugated steel plate in real time.

[0061] In addition, during the grinding process of the corrugated steel plate, the controller controls the dust collection equipment to work, and absorbs the waste chips and dust ground at the flap wheel 33 into the dust removal bag (not shown in the figure) through the dust collection pipe 6. After one end of the corrugated steel plate is ground, the controller controls the pulling assembly 5 to work, so that the second electric telescopic rod 50 contracts, driving the pulling slider 51 and the electromagnetic adsorption plate 52 to move to the grounded corrugated steel plate, and the electromagnetic adsorption plate 52 is energized and magnetically adsorbed to the corrugated steel plate. The second electric telescopic rod 50 extends, thereby pulling the corrugated steel plate to move and gradually pulling out the grounded corrugated steel plate. After pulling it out, the relevant staff removes the corrugated steel plate and resets the components to complete the grinding of the corrugated steel plate.

[0062] The steel plate surface grinding and rust removal device provided in the embodiment of the present application can be used for grinding and rust removal of corrugated steel plates, and can also be used for grinding and rust removal of ordinary straight steel plates. When grinding and rust removal of straight steel plates, the feeding component 4 pushes the straight steel plate between the two grinding mechanisms 3, and the two grinding mechanisms 3 grind the surfaces of both sides of the steel plate. The pulling component 5 pulls the polished straight steel plate to gradually unload the material, and there is no need for the two grinding mechanisms 3 to move in a corrugated manner on the rust removal box 1, thereby realizing grinding and rust removal of straight steel plates.

[0063] In summary, the steel plate surface grinding and rust removal device of the embodiment of the present application can grind corrugated steel plates without the need for relevant staff to use a handheld grinder for grinding, thereby reducing the labor intensity of relevant staff and improving the efficiency of steel plate rust removal.
