Description

Technical Field

[0001] This application relates to the field of sheet metal processing equipment technology, specifically to a sheet metal oxide scale removal device. Background Technology

[0002] Metal sheets are metal plates manufactured through processes such as forging, rolling, or casting, such as steel plates and leaf springs. During the manufacturing process, metal sheets will produce an oxide layer. For example, during the manufacturing of leaf springs, leaf springs require multiple heating forging and precision rolling processes. During the heating process, the surface of the leaf spring comes into contact with high-temperature furnace gas, resulting in an oxidation reaction and the formation of an oxide scale 1 to 3 mm thick on the surface of the leaf spring.

[0003] If the oxide scale on the surface of the sheet material is not removed before processing, surface defects will appear, affecting the appearance and reducing the surface strength. In reality, some sheet materials only require heat treatment at the ends, thus only the oxide scale generated at the ends needs to be removed. For example, in the manufacturing process of leaf springs, the ends of the spring steel are heated and forged to stack and combine the spring steel. Existing methods for removing oxide scale from the ends of sheet materials include two approaches: one is to manually insert the ends of the sheet material into a high-pressure washer for cleaning and then pull it out by hand; the other is to use a large robotic arm to remove the oxide scale from the ends of one sheet material, place the sheet material in a designated position, and then remove the next sheet material for cleaning.

[0004] Regarding the aforementioned related technologies, the inventors believe that the existing methods for removing oxide scale from the ends of sheet metal involve manually or using a robotic arm to remove the oxide scale from the ends of a sheet metal and then placing it in a designated location before taking out the next sheet metal and removing the oxide scale from the ends. This increases the time required for removing oxide scale from the ends of the sheet metal, which wastes manpower and resources and results in low work efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a device for removing oxide scale from sheet metal, which saves manpower and resources on the one hand, and improves work efficiency on the other.

[0006] To solve the above-mentioned technical problems, the present invention provides a sheet metal oxide scale removal device, characterized in that it includes: a frame; a feeding mechanism, slidably mounted on the frame for receiving and moving sheet metal; a conveying mechanism, mounted on the frame, capable of receiving and transporting the sheet metal conveyed by the feeding mechanism, and capable of restricting the movement of the sheet metal in the vertical direction; a cleaning mechanism, disposed opposite to the conveying mechanism, capable of receiving the sheet metal conveyed by the conveying mechanism and cleaning the oxide scale of the sheet metal, wherein the conveying mechanism can eject the sheet metal after the cleaning mechanism has cleaned the oxide scale; a discharge plate, disposed on the frame and located below the conveying mechanism, capable of receiving the sheet metal ejected from the cleaning mechanism; and an auxiliary mechanism, disposed on the frame, capable of controlling the conveying mechanism to tilt so that the discharge port of the conveying mechanism is directly opposite the discharge plate when the conveying mechanism ejects the sheet metal; wherein, when the auxiliary mechanism controls the tilting of the conveying mechanism, it can simultaneously drive the feeding mechanism to move away from the cleaning mechanism.

[0007] By adopting the above technical solution, when it is necessary to clean the oxide scale of the board, the board to be cleaned is first received by the feeding structure and moved to the conveying mechanism. Then, the conveying mechanism receives the board conveyed by the feeding mechanism and transports the received board. During the conveying process, the conveying mechanism restricts the vertical movement of the board. Finally, the cleaning mechanism receives the board conveyed by the conveying mechanism and cleans the oxide scale of the board. After the cleaning mechanism cleans the oxide scale at one end of the board, the conveying mechanism exits the board. When the board is exited, the auxiliary mechanism controls the conveying mechanism to tilt so that the discharge port of the conveying mechanism is directly opposite the unloading plate, so that the board can be received by the unloading plate after exiting the cleaning mechanism, completing the cleaning of the oxide scale at one end of the board. Then, the above steps are repeated to clean the oxide scale of the next board. Meanwhile, the auxiliary mechanism can simultaneously drive the feeding mechanism to move away from the cleaning mechanism when the feeding mechanism is tilted, thereby reducing the probability of interference between the feeding mechanism and the board during the unloading process and reducing the probability of machine collision.

[0008] The feeding and conveying mechanisms enable automated feeding of the boards during the cleaning process, and automatically remove the boards after the oxide scale removal is complete, facilitating the cleaning of the next board. Furthermore, the auxiliary mechanisms facilitate the removal of boards onto the unloading plate and ensure sufficient space for the boards to pass through during this process, reducing the probability of collisions between the boards and the feeding mechanism.

[0009] Preferably, the feeding mechanism includes: two first support rods disposed on the frame, each first support rod having parallel translation grooves at the same height; two first support plates, each first support plate being slidably disposed within one of the translation grooves; two connecting plates, each connecting plate being connected to the bottom wall of one of the first support plates; a reinforcing plate fixedly connected between the two connecting plates; and multiple feeding rollers disposed between the two first support plates, each feeding roller having one fixedly connected to both ends. A first connecting rod rotatably connected to the first support plate; a first motor, which is fixedly mounted on the reinforcing plate, with the output shaft of the first motor fixedly connected to a first pulley; a second pulley, which is fixedly mounted on any one of the plurality of first connecting rods, with a first belt sleeved between the first pulley and the second pulley; wherein, the plurality of first connecting rods are evenly divided into two groups according to their positions on both sides of the feeding roller, and a first sprocket is fixedly sleeved on the group of first connecting rods away from the first pulley, and a first chain meshing on the plurality of first sprockets to enable the first pulley and the second pulley to rotate together.

[0010] By adopting the above technical solution, when material feeding is required, the first motor on the reinforcing plate is first started. The output shaft of the first motor drives the first pulley to rotate. The first pulley drives the second pulley to rotate via a belt. The second pulley drives one of the feeding rollers to rotate. The feeding roller rotates together with the first sprocket and the first chain at one end, thereby transporting the sheet material to the next mechanism. At the same time, the feeding mechanism can slide on the frame via a translation groove, which facilitates material feeding. When the feeding mechanism moves away from the conveying mechanism, it also ensures that the sheet material will not interfere with the feeding mechanism when unloading.

[0011] The first motor and the feeding roller enable the feeding roller to rotate, thereby moving the sheet material to the conveying mechanism. The translation groove allows the feeding mechanism to slide on the frame, facilitating the feeding and unloading process and improving work efficiency.

[0012] Preferably, the feeding mechanism includes: two second support rods mounted on the frame, the two second support rods being at the same height and parallel to each other; multiple feeding rollers disposed between the two second support rods, each feeding roller having a second connecting rod fixedly connected to both ends of the roller and rotatably connected to the second support rod; and multiple extrusion rollers, each extrusion roller having a second reinforcing plate fixedly connected to the upper surface of each second support rod, a sliding groove formed on the opposite sidewalls of the two second reinforcing plates, an extrusion rod slidably disposed in each sliding groove, and a reset rod fixedly connected between each extrusion rod and the top wall of the sliding groove. A spring; multiple extrusion rollers are disposed between two extrusion rods, and each extrusion roller is fixedly connected to a third connecting rod rotatably connected to the extrusion rod at both ends; a third pulley; the third pulley and any one of the multiple second connecting rods are fixedly sleeved after passing through the second support rod; a second motor; a fourth pulley is fixedly sleeved on the drive shaft of the second motor, and a second belt is sleeved on the fourth pulley and the third pulley; wherein, the multiple second connecting rods are divided into two groups according to their positions on both sides of the feed roller, and a second sprocket is fixedly sleeved on each of the second connecting rods in one group, and a second chain meshes with the multiple second sprockets to enable the second sprockets to rotate together.

[0013] By adopting the above technical solution, when receiving and transporting the sheet material from the feeding mechanism, the second motor is first started. The output shaft of the second motor drives the fourth pulley to rotate, which in turn drives the third pulley via a belt. The third pulley drives one of the conveying rollers to rotate, and finally, the conveying roller rotates together with the second sprocket and the second chain at one end, thus enabling the sheet material to continue to be transported. The squeeze roller and the return spring are positioned above the conveying roller. When the sheet material moves onto the conveying roller, the squeeze roller and the return spring can adapt to the thickness of the sheet material, thereby making the transport of the sheet material more stable.

[0014] The system uses multiple conveying rollers to receive the boards fed by the feeding mechanism. The second motor drives the conveying rollers to rotate, thus transporting the boards to the cleaning mechanism for cleaning. The squeeze rollers allow the boards to adapt to their thickness during transport, thus limiting their vertical movement and making them more stable. After cleaning, the second motor reverses to remove the boards, saving manpower and resources.

[0015] The design of the squeeze roller and return spring not only limits the vertical movement of the board from above during the conveying process to the cleaning process, reducing the probability of deflection, but also provides vertical movement margin for the board. When the board reaches the cleaning position and its horizontal movement is restricted, the clamping effect on the board is partially released, preventing the board from continuing to penetrate deeper into the cleaning device and causing a collision. In other words, it restricts the vertical movement of the board during transportation and provides vertical movement margin when the horizontal movement of the board is restricted, making the design quite flexible.

[0016] Preferably, the auxiliary mechanism includes: two fixed rods fixedly connected to the frame, the two fixed rods being at the same height and parallel to each other; two first hinge rods, each hinged to one end of a fixed rod; two second hinge rods, each hinged to one end of a fixed rod; two base plates fixedly connected to the frame, the two base plates being at the same height and parallel to each other, each base plate having a movable groove, and a rotating pin rotatably connected to the end of the first and second hinge rods away from the fixed rod, each rotating pin being able to slide along the movable groove; multiple third hinge rods disposed between the second hinge rod and the second support rod, one end of the third hinge rod and the second hinge rod being hinged to the second support rod; and a linear actuator, the first hinge rod having a push groove, a push rod slidably connected in the push groove, the push rod being hinged to the drive rod of the linear actuator.

[0017] A linkage rod is provided, wherein the first connecting rod passes through the translation groove and is hinged to the end of the linkage rod away from the second hinge rod; the end of the second hinge rod away from the fixed rod is rotatably connected to a sliding rod; one end of the linkage rod is hinged to the sliding rod; the linkage rod has a sliding groove for the sliding rod to slide and an upper sliding groove for the first connecting rod to slide; two movable rods are provided and are parallel to each other; one end of the movable rod is hinged to the end of the first hinge rod away from the fixed rod and the hinge point of the first hinge rod; the other end of the movable rod away from the hinge point of the first hinge rod and the hinge point of the second hinge rod away from the hinge point of the second hinge rod and the fixed rod; wherein the two first hinge rods are at the same height and are parallel to each other, the two second hinge rods are at the same height and are parallel to each other, and the fixed rod and the movable rod are parallel to each other.

[0018] By adopting the above technical solution, when the board material is driven out of the cleaning mechanism by the conveying mechanism, a linear driver pulls the push rod in the push groove, thereby causing the rotating pins at one end of the first and second hinge rods to slide along the moving slide. The second hinge rod drives multiple third hinge rods to move, finally causing the conveying mechanism to tilt until the board material falls. At the same time, due to the setting of the linkage rod, the movement of the second hinge rod can drive the sliding rod to move in the sliding groove of the linkage rod. Meanwhile, the first connecting rod drives the feeding roller to move away from the conveying mechanism, so that the board material is not affected by the feeding mechanism, which facilitates the falling of the board material and also makes it convenient for people to load the material. After the board material falls, the linear driver pushes the first hinge rod, thereby causing the second and third hinge rods to return to their initial state, so as to continue to convey the board material to the cleaning mechanism. This realizes automatic unloading of the board material and facilitates people to load the material, thereby improving work efficiency.

[0019] The auxiliary mechanism allows the conveying mechanism to move as it moves, causing the conveying mechanism to tilt. The cleaned boards then fall from the conveying mechanism. Simultaneously, the linkage rod moves the loading mechanism away from the conveying mechanism, preventing interference with the loading mechanism when the boards fall. Finally, the auxiliary mechanism restores the conveying mechanism to its initial state for continued conveying.

[0020] Preferably, the cleaning mechanism includes: a cleaning tank with an opening on one side wall facing the material conveying mechanism; a water pipe surrounding the side wall of the cleaning tank, with multiple outlets of the water pipe penetrating the side wall of the cleaning tank; multiple nozzles fixedly connected to the outlets of the water pipe; a high-pressure water pump located on one side of the cleaning tank and fixedly connected to the inlet of the water pipe; and a water storage tank located on one side of the high-pressure water pump and fixedly connected to the high-pressure water pump.

[0021] By adopting the above technical solution, the water in the water storage tank enters the water pipe through a high-pressure water pump, thereby increasing the water pressure. Multiple nozzles in the cleaning tank are used to clean one end of the board, enhancing the cleaning effect.

[0022] The high-pressure water pump increases water pressure, thus enhancing the rinsing effect on the board. The multiple nozzles allow for cleaning of all five sides of the board, increasing the probability of removing oxide scale.

[0023] Preferably, a plate limiting plate is fixedly connected to the side wall of the cleaning tank away from the conveying roller.

[0024] By adopting the above technical solution, the plate limiting plate can restrict the position of the plate in the cleaning mechanism, so that the plate will not collide with the machine. On the other hand, in conjunction with the setting of the extrusion roller and the return spring, it can also restrict the vertical movement of the plate.

[0025] Preferably, the linear actuator can be a device such as a cylinder, hydraulic cylinder, or electromagnetic push rod whose output shaft can achieve linear movement.

[0026] By adopting the above technical solution, the rotation of the motor can be changed into linear movement through the setting of the linear drive, thereby enabling the movement of the auxiliary mechanism to be well realized.

[0027] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0028] 1. The feeding and conveying mechanisms enable automatic feeding of the sheet metal during the cleaning process, and automatically remove the sheet metal after the oxide scale removal is complete, facilitating the cleaning of the oxide scale on the next sheet metal. Furthermore, the auxiliary mechanisms facilitate the removal of the sheet metal to the unloading plate and ensure sufficient space for the sheet metal to pass through during this process, reducing the probability of collisions between the sheet metal and the feeding mechanism.

[0029] 2. The setting of the extrusion roller and the return spring can not only limit the vertical movement of the board from above during the conveying of the board into the cleaning mechanism, reducing the probability of the board deflection during the conveying process, but also provide the board with a vertical movement margin. When the board reaches the cleaning position and its horizontal movement is restricted, the clamping effect on the board is partially released, so that the board will not continue to go deeper into the cleaning device and cause a collision. That is, it restricts the vertical movement of the board during the conveying process and provides a vertical movement margin when the horizontal movement of the board is restricted, which is quite flexible.

[0030] 3. The auxiliary mechanism enables the conveying mechanism to move when it moves, causing the conveying mechanism to tilt. The cleaned boards can then fall from the conveying mechanism. At the same time, the linkage rod can move the feeding mechanism away from the conveying mechanism, so that the boards will not interfere with the feeding mechanism when they fall. Finally, the auxiliary mechanism restores the conveying mechanism to its initial state so that the conveying can continue. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0038] Reference Figure 1 The sheet metal oxide scale removal device includes a frame 1 and a feeding plate 5 fixedly connected to the frame 1. The frame 1 is equipped with a feeding mechanism 2 that can receive and move the sheet metal, a conveying mechanism 3 that can receive the sheet metal conveyed by the feeding mechanism 2 and transport the received sheet metal and restrict the vertical movement of the sheet metal, and a cleaning mechanism 4 that can receive the sheet metal conveyed by the conveying mechanism 3 and clean the oxide scale of the sheet metal.

[0039] When it is necessary to clean the oxide scale of the board, the feeding mechanism 2 first receives the board to be cleaned and moves it to the conveying mechanism 3. Then, the conveying mechanism 3 receives the board conveyed by the feeding mechanism 2 and transports it. During the conveying process, the conveying mechanism 3 restricts the vertical movement of the board. Finally, the cleaning mechanism 4 receives the board conveyed by the conveying mechanism 3 and cleans the oxide scale. After the cleaning mechanism 4 cleans the oxide scale at one end of the board, the conveying mechanism 3 exits the board. When the board is exited, the auxiliary mechanism 6 controls the conveying mechanism 3 to tilt so that the discharge port of the conveying mechanism 3 is directly facing the unloading plate 5, so that the board can be received by the unloading plate 5 after exiting the cleaning mechanism 4, completing the cleaning of the oxide scale at one end of the board. Then, the above steps are repeated to clean the oxide scale of the next board. Meanwhile, when the material conveying mechanism 3 is tilted, the auxiliary mechanism 6 can simultaneously drive the feeding mechanism 2 to move away from the cleaning mechanism 4, thereby reducing the probability of interference between the feeding mechanism 2 and the material during the unloading process and reducing the probability of machine collision.

[0040] Reference Figure 1 and Figure 2 The feeding mechanism 2 includes a first support rod 21 fixedly connected to the frame 1. Each first support rod 21 has a translation groove 211 at the same height and parallel to each other. Two translation grooves 211 are slidably connected to a first support plate 22. A connecting plate 221 is fixedly connected to the bottom wall of each first support plate 22. A first reinforcing plate 222 is fixedly connected between two connecting plates 221. Multiple feeding rollers 23 on the same horizontal plane are rotatably connected between two first support plates 22. A first connecting rod 24 is fixedly connected to both ends of each feeding roller 23. The end of each first connecting rod 24 away from the feeding roller 23 is rotatably connected to a first reinforcing plate 222. A first motor 25 is fixedly installed on the upper surface of the support plate 22 and the first reinforcing plate 222. The output shaft of the first motor 25 is fixedly connected to the first pulley 251. A second pulley 252 is fixedly installed on any one of the first connecting rods 24 and the second pulley 252 is positioned above the first pulley 251. A first belt 253 is sleeved between the first pulley 251 and the second pulley 252, which can drive the first pulley 251 and the second pulley 252 to rotate together. A first sprocket 26 is fixedly sleeved on the end of each first connecting rod 24 away from the first pulley 251. A first chain 27 that can make the multiple first sprockets 26 rotate together is meshed on the multiple first sprockets 26.

[0041] When it is necessary to receive and move the board, the first motor 25 is started to drive the first pulley 251 to rotate. The first pulley 251 drives the second pulley 252 to start rotating through the first belt 253. Thus, the second pulley 252 drives the feeding roller 23 to start rotating. At the same time, due to the arrangement of the first sprocket 26 and the first chain 27, multiple feeding rollers 23 can rotate together, placing the board on the feeding roller 23. The rotation of the feeding roller 23 can drive the board to move. The arrangement of the feeding mechanism 2 can facilitate the transportation of the board to the next mechanism.

[0042] Reference Figure 1 , Figure 3 and Figure 5 The feeding mechanism 3 includes two second support rods 31 mounted on the frame 1 at the same height and parallel to each other. Multiple feeding rollers 32, at the same height as the feeding roller 23, are arranged between the two second support rods 31. Each feeding roller 32 has a second connecting rod 321 fixedly connected to both ends. The end of each second connecting rod 321 away from the feeding roller 32 is rotatably connected to the second support rod 31. A second reinforcing plate 34 is fixedly connected to the upper surface of each second support rod 31. A sliding groove 341 is formed on the opposite sidewalls of the two second reinforcing plates 34. A pressing rod 342 is slidably arranged in each sliding groove 341. A return spring 343 is fixedly connected between each pressing rod 342 and the top wall of the sliding groove 341. Multiple pressing rollers 33 are arranged between the two pressing rods 342. Each end of the pressure roller 33 is fixedly connected to a third connecting rod 331. The end of each third connecting rod 331 away from the pressure roller 33 is rotatably connected to the pressure rod 342. Any one of the multiple second connecting rods 321 passes through the second support rod 31 and is fixedly fitted with a third pulley 35. A second motor 36 is installed on the frame 1. The output shaft of the second motor 36 is fixedly fitted with a fourth pulley 361. A second belt 362 that can drive the fourth pulley 361 and the third pulley 35 to rotate together is fitted between the fourth pulley 361 and the third pulley 35. The multiple second connecting rods 321 are divided into two groups according to the positions on both sides of the feeding roller 23. A second sprocket 37 is fixedly fitted on each of the two groups of second connecting rods 321. A second chain 38 that can make the multiple second sprockets 37 rotate together is meshed on the multiple second sprockets 37.

[0043] When it is necessary to receive the sheet material and restrict its vertical movement, the second motor 36 is started first. The second motor 36 drives the fourth pulley 361 to rotate. The fourth pulley 361 drives the third pulley 35 to rotate via the second belt 362. The third pulley 35 drives the feeding rollers 32 to rotate. Due to the arrangement of the second sprocket 37 and the second chain 38, multiple feeding rollers 32 rotate together. When the sheet material moves onto the feeding rollers 32, the multiple feeding rollers 32 drive the sheet material to move. Multiple extrusion rollers 33 are arranged between the two second reinforcing plates 34. When the sheet material enters the extrusion... When the pressure roller 33 and the conveying roller 32 are in contact, the plate pushes up the pressure roller 33, and the pressure roller 33 drives the return spring 343 to start contracting. The return spring 343 generates a vertically downward force, which can restrict the vertical movement of the plate. The conveying mechanism 3 can receive the plate transported from the feeding mechanism 2, and at the same time restrict the vertical movement of the plate so that the plate is not easy to fall off. After cleaning, the second motor 36 reverses to drive the plate out. The conveying mechanism 3 can make the plate move stably and drive the plate out, which improves the work efficiency.

[0044] The compression roller 33 and the return spring 343 not only limit the vertical movement of the plate from above during the conveying of the plate into the cleaning mechanism 4, reducing the probability of the plate deflecting during the conveying process, but also provide a vertical movement margin for the plate. When the plate reaches the cleaning position and its horizontal movement is restricted, the clamping effect on the plate is partially released, so that the plate will not continue to penetrate into the cleaning device and cause a collision. In other words, the vertical movement of the plate is restricted during the transport of the plate, and a vertical movement margin is provided when the horizontal movement of the plate is restricted. The setting is quite flexible.

[0045] Reference Figure 1 and Figure 3 The auxiliary mechanism 6 includes a linear actuator 66 and two fixed rods 61 fixedly connected to the frame 1. Each fixed rod 61 has a first hinge rod 62 hinged at one end. Each fixed rod 61 has a second hinge rod 63 hinged at the end away from the fixed rod 61 and the first hinge rod 62. Each second hinge rod 63 has a moving rod 68 hinged at the end away from the fixed rod 61 and parallel to the fixed rod 61. The moving rod 68 has a hinged end away from the second hinge rod 63 and the moving rod 68 hinged to the first hinge rod 62. The bottom of the frame 1 is fixedly connected to two base plates 64 at the same height and parallel to each other. Each base plate 64 has two moving grooves 641. Each first hinge rod 62 and each second hinge rod 63 has a rotating pin 642 rotatably connected at the end away from the fixed rod 61. Each rotating pin 642 can slide along each moving groove 641.

[0046] The second hinge rod 63 is rotatably connected to the fourth pulley 361 at one end near the fixed rod 61.

[0047] Multiple third hinge rods 65 are provided between each second hinge rod 63 and each second support rod 31. The bottom end of each third hinge rod 65 is fixedly connected to each second hinge rod 63, and the top end of each third hinge rod 65 is hinged to each second support rod 31. Each first hinge rod 62 has a push groove 661 near the moving rod 68. A push rod 662 is slidably connected in one of the push grooves 661. The push rod 662 is rotatably connected to a top block 663, and the top block 663 is bolted to... The drive rod of the linear actuator 66 has a first connecting rod 24 that passes through the translation groove 211 and is hinged to a connecting rod 67. The end of the connecting rod 67 away from the second hinge rod 63 is hinged to the first connecting rod 24. The end of the second hinge rod 63 away from the fixed rod 61 is rotatably connected to a sliding rod 671. The end of the connecting rod 67 near the second hinge rod 63 is hinged to the sliding rod 671. The connecting rod 67 has a sliding groove 672 for sliding of the sliding rod 671 and an upper sliding groove 673 for sliding of the first connecting rod 24.

[0048] Among them, the two fixed rods 61, the two first hinge rods 62 and the two second hinge rods 63 are located at the same height and are parallel to each other. The linear actuator 66 can be a device such as a cylinder, hydraulic cylinder or electromagnetic push rod 662, whose output shaft can achieve linear movement.

[0049] When it is necessary to tilt the conveying mechanism 3, the linear actuator 66 is activated. The drive rod of the linear actuator 66 pulls the push rod 662 in the push groove 661, thereby driving the first hinge rod 62 to move. The first hinge rod 62 drives the moving rod 68 and the second hinge rod 63 to move. The second hinge rod 63 drives the third hinge rod 65 to move, thereby tilting the conveying mechanism 3. The linkage rod 67 is set so that while the conveying mechanism 3 is tilted, the feeding mechanism 2 is driven to move away from the conveying mechanism 3, so that the board will not interfere with the feeding mechanism 2 when it falls and can be easily fed. Automatic unloading and easy feeding are realized, thereby improving work efficiency.

[0050] Reference Figure 1 and Figure 4 The cleaning mechanism 4 includes a cleaning tank 41 facing the conveying mechanism 3. The side wall of the cleaning tank 41 facing the conveying mechanism 3 is set as an opening. Except for the side wall at the opening, the cleaning tank 41 is surrounded by water pipes 42. The water pipes 42 are configured with multiple water outlets and one water inlet. Each water outlet is fixedly connected to a nozzle 43. The water inlet is fixedly connected to a high-pressure water pump 44. The high-pressure water pump 44 is bolted to a base 8. The high-pressure water pump 44 is fixedly connected to a water storage tank 45 fixedly connected to the base 8.

[0051] The cleaning box 41 has a plate limiting plate 7 fixedly connected to the side wall away from the conveying roller 32, and five nozzles 43 are provided on the five inner walls of the cleaning box 41 to clean the plate.

[0052] When the board needs to be cleaned, the conveying mechanism 3 moves the board into the cleaning tank 41. The high-pressure water pump 44 causes water to enter the water pipe 42 and spray it out from multiple nozzles 43. High-pressure water is used to clean one end of the board. The board limiting plate 7 prevents the board from colliding with the cleaning tank 41. The use of multiple nozzles 43 improves the cleaning effect.

[0053] The implementation principle of the oxide scale removal device for sheet metal in this application embodiment is as follows: When it is necessary to remove oxide scale from sheet metal, the sheet metal is first placed on the feeding roller 23. The first motor 25 is started to drive the feeding roller 23 to rotate together, so that the sheet metal enters the conveying roller 32. The second motor 36 is started to make the conveying roller 32 start to rotate. At the same time, the squeezing roller 33 and the return spring 343 restrict the vertical movement of the sheet metal, thereby driving the sheet metal into the cleaning tank 41. The high-pressure water pump 44 is turned on, so that water enters the water pipe 42 and then cleans one end of the sheet metal through the nozzle 43. When the sheet metal enters the sheet metal limiting plate 7, the second motor 36 starts to reverse, thereby driving the sheet metal out of the cleaning tank 41. At the same time, the linear driver 66 is started to drive the auxiliary mechanism 6. The auxiliary mechanism 6 drives the conveying mechanism 3 to start to tilt. Through the linkage rod 67, the feeding mechanism 2 can be moved away from the feeding mechanism 2. When the sheet metal falls into the unloading plate 5, the linear driver 66 drives the auxiliary mechanism 6 to return to the initial state. Then the above steps are repeated to achieve the cleaning of oxide scale for the next sheet metal.
