[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0039] Embodiment 1:

[0040] When metal sheets are made, bulges or depressions often appear on the surface of the metal sheets, which reduces the quality and aesthetics of the metal sheets.

[0041] In order to solve the above problems, this embodiment describes the structure and working principle of a metal plate processing and leveling machine, specifically:

[0042] like Figure 1 As shown, the present application provides a metal plate processing and leveling machine, including a support mechanism 1, the support mechanism 1 includes a base frame 11, a platform 12 for placing and conveying metal plates is fixedly installed on the upper end of the base frame 11, and a leveling mechanism 2 for flattening the metal plate is arranged on the upper end of the platform 12, and the leveling mechanism 2 flattens the raised parts on the metal plate by rolling. It should be noted that the leveling mechanism 2 is provided with two groups of the same structure, and the two groups of leveling mechanisms 2 are arranged along the conveying direction of the metal plate;

[0043] like Figure 1-Figure 4 As shown, the leveling mechanism 2 includes a panel 13 fixed on the base frame 11, the panel 13 is arranged on one side of the platform 12, and a top plate 21 is fixedly installed on the panel 13, a guide column 214 is fixedly installed between the top plate 21 and the panel 13, and a slide 213 is slidably arranged on the guide column 214, and a vertical plate 22 is fixedly installed on the slide 213, so that the slide 213 can slide in the vertical direction along the guide column 214, thereby driving the vertical plate 22 to move synchronously in the vertical direction;

[0044] At the same time, a first screw rod 211 is installed between the top plate 21 and the panel 13, and a connecting seat 212 is provided on the first screw rod 211. The connecting seat 212 is fixedly installed with the vertical plate 22, so that when the first screw rod 211 rotates, the connecting seat 212 can drive the vertical plate 22 to slide in the vertical direction;

[0045] In order to facilitate the operation of the staff, the top of the first screw rod 211 protrudes from the top plate 21 and is installed with a hand wheel 210, so that the staff can control the height position of the vertical plate 22 through the hand wheel 210;

[0046] Continue to refer Figure 3-Figure 4 A first motor 23 is fixedly mounted on the upper end of the vertical plate 22, a driving wheel 24 is fixedly mounted on the output end of the first motor 23, and a first bearing seat 29 is fixedly mounted on the lower end of the vertical plate 22, a leveling shaft 28 is mounted on the first bearing seat 29, a driven wheel 25 is fixedly mounted on one end of the leveling shaft 28, and a belt 26 is arranged between the driven wheel 25 and the driving wheel 24, so that when the first motor 23 is started, the driving wheel 24, the belt 26 and the driven wheel 25 can drive the leveling shaft 28 to rotate;

[0047] At the same time, a leveling roller 27 is fixedly installed at the other end of the leveling shaft 28, and the leveling roller 27 is located at the upper end of the platform 12, so that the leveling roller 27 can rotate synchronously with the leveling shaft 28 and roll the metal plate passing through the platform 12;

[0048] To summarize, when the metal plate needs to be leveled, the metal plate is first placed on the platform 12, and then the staff manually adjusts the hand wheel 210 so that the leveling roller 27 is in a suitable position, and then starts the first motor 23 to drive the leveling roller 27 to rotate, so as to level the metal plate by rolling.

[0049] In order to realize the conveying of the metal plate on the platform 12, the continuous rolling and flattening of the flattening roller 27 is realized, such as Figure 2 and Figure 6 As shown, a second motor 15 is fixedly installed on the platform 12 at the position where the metal sheet is fed, and an introduction roller 16 is fixedly installed at the output end of the second motor 15. The introduction roller 16 is installed with a bearing on the platform 12, so that the introduction roller 16 can rotate under the drive of the second motor 15 and introduce the metal sheet at the upper end of the introduction roller 16 onto the platform 12;

[0050] At the same time, a lead-out roller 14 is mounted on a bearing at one end of the platform 12 away from the lead-in roller 16 , and the lead-out roller 14 is used to lead the flattened metal plate to the next process.

[0051] In this embodiment, the two sets of leveling rollers 27 gradually decrease the leveling height along the conveying direction of the metal plate, thereby realizing step-by-step leveling of the metal plate to achieve a better leveling effect.

[0052] A plurality of pressing assemblies are arranged on the platform 12, and the pressing assemblies are arranged on both sides of the leveling roller 27, so as to press the metal plate to prevent the metal plate from deviating during the conveying process of the metal plate. Specifically:

[0053] like Figure 2 and Figure 5 As shown, the pressing assembly includes a first bracket 17 fixedly mounted on both sides of the platform 12, and a movable pin 18 is vertically penetrated at the upper end of the first bracket 17. It should be noted that a through hole (not marked in the figure) is provided at the upper end of the first bracket 17, and the movable pin 18 is penetrated in the through hole;

[0054] At the same time, cylindrical heads 112 are provided at both ends of the movable pin 18, and the cylindrical heads 112 are used to prevent the movable pin 18 from slipping out of the through hole, and a first spring 19 is sleeved on the movable pin 18, and the first spring 19 is located between the cylindrical head 112 at the lower end and the first bracket 17, so that the movable pin 18 can slide vertically in the through hole and be reset by the first spring 19;

[0055] A holding shaft 110 is sleeved between the cylindrical head 112 at the upper end and the first bracket 17. The holding shaft 110 is transversely arranged on the platform 12. A holding roller 111 is mounted on the bearing of the holding shaft 110. When the metal plate is rolled, it passes through the bottom of the holding roller 111 and is held by the holding roller 111 to prevent the metal plate from deviating.

[0056] Furthermore, due to the action of the first spring 19 , when metal plates of different thicknesses pass through the pressing roller 111 , they can all be pressed by the pressing roller 111 , thereby increasing the application range of the pressing assembly.

[0057] Embodiment 2:

[0058] Since metal plates are easily contaminated with particle impurities during the leveling process, these particle impurities adhere to the rollers of the leveling machine when the metal plates are leveled, and the rollers drive the metal plates to press the metal plates, resulting in scratches on the metal plates, causing damage to the metal plates, thereby affecting product quality;

[0059] In order to solve the above problems, Figure 2 and Figure 5 As shown, a pre-pressing mechanism 3 is provided between the introduction roller 16 and the leveling roller 27, and the pre-pressing mechanism 3 is used to remove impurities on the surface of the metal plate, specifically:

[0060] like Figure 7-Figure 8 As shown, the pre-pressing mechanism 3 includes a plurality of second brackets 31 fixedly mounted on both sides of the platform 12, mounting plates 32 are fixedly mounted on two opposite second brackets 31, and translation components are mounted at the bottom of the two mounting plates 32, which are the power source of the pre-pressing mechanism 3;

[0061] The translation assembly includes a first seat body 36 fixedly mounted on the bottom of one set of mounting plates 32, and a second seat body 310 fixedly mounted on the bottom of another set of mounting plates 32, and a slide bar 38 fixedly mounted between the first seat body 36 and the second seat body 310, and the slide bar 38 connects the first seat body 36 and the second seat body 310 into a whole;

[0062] Meanwhile, a third motor 34 is fixedly mounted on the first seat body 36, and a second screw rod 37 is fixedly mounted on the output end of the third motor 34. The bearings at both ends of the second screw rod 37 are mounted on the first seat body 36 and the second seat body 310, so that the second screw rod 37 can rotate under the drive of the third motor 34;

[0063] A slide plate 35 is provided on the second screw rod 37 for transmission, and both ends of the slide plate 35 are slidably provided on two sets of slide rods 38, so that during the rotation of the second screw rod 37, the slide plate 35 can slide along the length direction of the slide rod 38;

[0064] like Figure 8-Figure 10 As shown, a support plate 33 is fixedly installed at the bottom of the slide plate 35, and second bearing seats 315 are installed at both ends of the bottom of the support plate 33. Pre-pressing rollers 311 are installed on the two sets of second bearing seats 315, so that when the slide plate 35 moves, the support plate 33 can be driven to move synchronously, and then the pre-pressing rollers 311 can be driven to move;

[0065] In summary, when the metal sheet is located between the introduction roller 16 and the leveling roller 27, the third motor 34 is started, thereby driving the slide plate 35 and the support plate 33 to move through the transmission of the second screw rod 37, and then driving the pre-pressing roller 311 to reciprocate along the direction of conveying the metal sheet;

[0066] During the reciprocating motion of the pre-pressing roller 311, the pre-pressing roller 311 contacts the upper surface of the metal plate, thereby realizing the pre-pressing operation of the metal plate. At the same time, during the contact between the pre-pressing roller 311 and the metal plate, the impurities on the surface of the metal plate are rolled and adsorbed on the pre-pressing roller 311, thereby the surface of the metal plate can be cleaned to a certain extent.

[0067] In order to adapt to the pre-stressing operation of metal plates with different thicknesses, a second spring 316 is fixedly installed between the second bearing seat 315 and the support plate 33. The second spring 316 applies downward pressure to the second bearing seat 315, so that the pre-stressing roller 311 can fit tightly on the metal plate and can be adaptively adjusted when encountering metal plates of different thicknesses.

[0068] In order to remove the impurities adhering to the pre-pressing roller 311 to prevent the metal sheet from being contaminated in the subsequent pre-pressing process, Figure 8 and Fig.10As shown, a collecting box 312 is fixedly installed at the bottom of the support plate 33 near the input position of the metal plate, and a scraping portion 313 is provided at a position of the collecting box 312 near the pre-pressing roller 311. The scraping portion 313 contacts the pre-pressing roller 311 to scrape off impurities adhering to the pre-pressing roller 311;

[0069] It should be noted that a storage portion (not shown in the figure) is provided at the bottom of the collecting box 312, and the storage portion is used to store scraped impurities. At the same time, the position of the scraping portion 313 is higher than the position of the storage portion, and a material transfer slope is formed, so that the impurities scraped by the scraping portion 313 can enter the position of the storage portion through the material transfer slope, so as to facilitate the collection and storage of impurities;

[0070] In this embodiment, when the pre-pressing roller 311 moves in the opposite direction of the metal plate conveying, the metal plate can be scraped. However, when the pre-pressing roller 311 moves in the direction of the metal plate conveying, due to the location of the scraping portion 313, the impurities cannot be conveyed to the collecting box 312, thereby causing contamination to the metal plate.

[0071] In order to solve the above problems, Figure 8 and Fig.10 As shown, a seat cylinder 39 is fixedly installed on the top of the second bearing seat 315, and a ring 314 is fixedly installed on the bottom of the support plate 33. The ring 314 is sleeved on the outer ring of the seat cylinder 39, so that during the vertical movement of the second bearing seat 315, the second bearing seat 315 can be limited by the cooperation of the seat cylinder 39 and the ring 314;

[0072] At the same time, a first electromagnet (not shown in the figure) is arranged at the top of the seat tube 39, and the position on the support plate 33 corresponding to the seat tube 39 is made of magnetic material, so that when the first electromagnet is energized and has magnetism, it can be adsorbed on the bottom of the support plate 33;

[0073] In this embodiment, a PLC control system is also provided to control the coordinated operation of various electrical components;

[0074] To sum up, when the pre-pressing roller 311 moves along the direction of metal plate conveying, the PLC control system sends a signal to energize the first electromagnet and make it magnetic, thereby adsorbing the seat tube 39 to the bottom of the support plate 33, and then causing the pre-pressing roller 311 to rise and be in a suspended state, and thus unable to contact the metal plate, so as to avoid contamination of the metal plate by the pre-pressing roller 311.

[0075] Embodiment three:

[0076] In the above embodiment, the pre-pressing roller 311 needs to be in rolling contact with the metal plate, so that the impurities on the metal plate can be adhered to the pre-pressing roller 311. However, due to the uneven surface of the metal plate, when the pre-pressing roller 311 is in a local raised position of the metal plate, most of the positions on the pre-pressing roller 311 cannot be in contact with the metal plate, resulting in that the impurities on the metal plate that are not in contact with the pre-pressing roller 311 cannot be cleaned;

[0077] In order to solve the above problems, Fig.10 As shown, a switch 317 is provided at the upper end of the seat tube 39, and a second electromagnet (not shown in the figure) is provided at the outer ring of the pre-pressing roller 311. The second electromagnet is electrically connected to the switch 317, so that when the switch 317 is pressed, the second electromagnet can be energized and has magnetism, thereby making the pre-pressing roller 311 magnetic and able to absorb impurities on the metal plate. In this embodiment, the metal plate is made of magnetic metal material, so the impurities attached to the metal plate are also made of magnetic material;

[0078] Through the above arrangement, when the pre-pressing roller 311 is in the local raised position of the metal plate, it will drive the second bearing seat 315 to move upward, thereby driving the seat tube 39 to move upward synchronously, and the switch 317 at the upper end of the seat tube 39 is pressed, so that the second electromagnet is energized and has magnetism, and the pre-pressing roller 311 has magnetism, so that impurities can be adsorbed on the surface of the pre-pressing roller 311 by magnetic force without contacting the metal plate, and no matter the pre-pressing roller 311 moves in the opposite direction of the metal plate conveying. Or the pre-pressing roller 311 moves in the direction of the metal plate conveying, the impurities can be magnetically adsorbed without contaminating the metal plate;

[0079] At the same time, when the pre-pressing roller 311 is magnetically adsorbed, because the contact area with the metal plate is small and the time is short, the pre-pressing roller 311 will not move a large distance toward the metal plate under the action of the magnetic force, and thus will not affect the movement of the pre-pressing roller 311.

[0080] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
