Description

Technical Field

[0001] This utility model belongs to the technical field of metal plate rolling equipment, and particularly relates to a metal plate rolling equipment. Background Technology

[0002] Metal sheets are used in various fields. When producing metal sheets, they need to be rolled. Rolling equipment is needed to flatten and stretch the metal sheets during the rolling process.

[0003] Patent No. CN219425457U discloses a metal plate rolling equipment, specifically a metal plate rolling device, including a base plate, a frame fixed to the upper side of the base plate, an electric telescopic rod installed on the upper side of the frame, a movable box fixed to the telescopic end of the electric telescopic rod, slide rails on both sides of the interior of the movable box, and a cylinder installed at the rear of the movable box. A movable plate is fixed to the telescopic end of the cylinder, and two connecting rods are fixed to both ends of the movable plate. Rollers are fixed to the other ends of the two connecting rods. This utility model, through a positioning mechanism, can fix the metal plate, avoiding problems such as uneven force on the metal plate and one end lifting up when the metal plate is first rolled, which would affect the rolling effect and damage the device, thereby reducing the damage rate of the device. At the same time, it prevents the metal plate from moving during the rolling process, affecting the engraving effect, greatly improving the practicality of the device and effectively reducing the defect rate.

[0004] In existing technologies, a positioning mechanism can be used to fix the sheet material and prevent uneven stress on the sheet material. However, the following problems still exist in the overall use process: First, existing technologies usually use multiple sets of rolling rollers to extrude and shape the sheet material. However, there are certain gaps between the multiple sets of sheet materials, which causes the sheet material to bend downwards during transportation, which can easily cause the machine to jam and shorten its service life. Second, when the existing device rolls the sheet material, the sheet material is prone to skew. The existing device cannot detect the position of the sheet material, which affects the rolling quality of the sheet material. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a metal plate rolling equipment. By setting up structures such as hinge rods and support plates, it can support the sheet metal, solving the problem that gaps between multiple sheets can cause the sheets to bend downwards during transportation, which can easily lead to machine jamming. By setting up detection plates and pressure sensors, it can detect the sheet metal during transportation, solving the problem that the sheet metal is prone to tilting and that existing devices cannot detect the position of the sheet metal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal plate rolling mill, comprising a machine body, an upper pressure roller, a lower pressure roller, and a drive gearbox. The upper pressure roller is rotatably mounted inside the machine body. The lower pressure roller is rotatably mounted below the upper pressure roller on the inner wall of the machine body. A drive gearbox is mounted on one side of the lower pressure roller on the outer surface of the machine body. The drive gearbox is connected to the upper and lower pressure rollers. A support plate is slidably mounted between every two lower pressure rollers. Limiting sliders are mounted on both sides of each of the support plates. Detection boxes are slidably mounted on both sides of each of the limiting sliders. Detection plates capable of detecting the width of the sheet metal are slidably mounted inside each of the detection boxes. A scraper is slidably mounted inside each support plate, and the scraper slidably abuts against the lower pressure roller.

[0007] Preferably, each of the bottom end faces of the plurality of support plates is provided with a collection block, and each of the plurality of collection blocks is provided with a dust suction port on its outer surface, with the plurality of dust suction ports facing the outer surface of the support plate respectively.

[0008] Preferably, a second connecting pipe is provided at one end of the collecting block on the outer surface of the machine body, the second connecting pipe communicates with the interior of the collecting block, a collecting box is provided below the second connecting pipe, and a blower is provided on one side of the collecting box.

[0009] Preferably, each of the multiple support plates is provided with a preheating chamber, each of the multiple preheating chambers is provided with a heating element, each of the multiple heating elements is provided with a recessed connecting groove below it, and each of the multiple recessed connecting grooves is provided with a return groove on one side.

[0010] Preferably, one side of each of the plurality of sunken connecting slots is provided with a first connecting pipe on the outer surface of the machine body, and the first connecting pipe is connected to the blower.

[0011] Preferably, the machine body is internally rotatably provided with multiple bidirectional threaded rods, and each of the multiple bidirectional threaded rods is provided with a connecting rod. Each of the multiple bidirectional threaded rods is slidably provided with two threaded sleeves on its outer surface. Each of the multiple threaded sleeves is rotatably provided with a hinge rod on its end face. The multiple hinge rods are grouped in pairs, and each group of hinge rods is rotatably connected to the bottom end face of the support plate.

[0012] Preferably, each of the plurality of support plates is provided with a limiting rod inside, and the plurality of limiting rods are respectively slidably connected to the scraper.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] refer to Figure 1 , Figure 2 and Figure 3 A metal plate rolling equipment includes a machine body 10, an upper pressure roller 11, a lower pressure roller 12, and a drive gearbox 13. The upper pressure roller 11 is rotatably arranged inside the machine body 10. The lower pressure roller 12 is rotatably arranged on the inner wall of the machine body 10 below the upper pressure roller 11. The drive gearbox 13 is arranged on one side of the lower pressure roller 12 on the outer surface of the machine body 10. The drive gearbox 13 includes a gearbox structure and a drive motor, etc., and has the function of adjusting the speed and driving the shaft to rotate. It is a conventional existing equipment, and this solution will not be elaborated on further. The two rotating output ends of the drive gearbox 13 are respectively connected to the upper pressure roller 11 and the lower pressure roller 12. When rolling the metal sheet, the metal sheet is placed between the upper pressure roller 11 and the lower pressure roller 12, and the drive gearbox 13 is started. The drive gearbox 13 drives multiple upper pressure rollers 11 and lower pressure rollers 12 to rotate through the output shaft to roll the metal sheet. A support plate 14 is slidably arranged between every two lower pressure rollers 12. The support plate 14 can support the metal sheet and prevent the metal sheet from bending downward during transportation, thereby improving the rolling effect of the metal sheet.

[0027] Further reference Figure 1 , Figure 2 and Figure 3The machine body 10 has multiple bidirectional threaded rods 16 rotatably mounted inside, and connecting rods 17 are provided between each of the multiple bidirectional threaded rods 16. One end of one of the connecting rods 17 is provided with a first motor 18 on the outer surface of the machine body 10. Two threaded sleeves 19 are slidably mounted on the outer surface of each of the multiple bidirectional threaded rods 16, and the bidirectional threaded rods 16 and the threaded sleeves 19 are threadedly connected. The end faces of each of the multiple threaded sleeves 19 are rotatably mounted with hinge rods 20. The multiple hinge rods 20 are arranged in pairs, and each pair of hinge rods 20 is rotatably connected to the bottom end face of the support plate 14. Limiting sliders 22 are provided on both sides of the multiple support plates 14, and detection boxes 15 are slidably mounted on both sides of the multiple limiting sliders 22. The outer surface of the multiple detection boxes 15 is... Each surface is provided with a limiting groove 21, and the limiting slider 22 is slidably connected with the limiting groove 21. When the height of the support plate 14 needs to be adjusted, the first motor 18 is started first. The output shaft of the first motor 18 drives the connecting rod 17 to rotate. The connecting rod 17 drives the bidirectional threaded rod 16 to rotate. Multiple bidirectional threaded rods 16 drive the threaded sleeves 19 on the outer surface to slide relative to each other. Multiple threaded sleeves 19 drive the hinge rod 20 on the end face to move, so that the hinge rod 20 moves to a vertical state. During the movement, the two hinge rods 20 will push the support plate 14 upward, thereby changing the height of the support plate 14, so that the height of the support plate 14 can be adjusted to adapt to the processing needs of plates of different thicknesses.

[0028] Further reference Figure 2 , Figure 3 , Figure 5 and Figure 6 Each of the multiple testing boxes 15 has a sliding testing plate 38 capable of detecting the width of the sheet metal. Each of the multiple testing boxes 15 has a pressure sensor 36 inside, and the detection ends of the multiple pressure sensors 36 abut against the testing plates 38. Each of the multiple testing plates 38 has a second elastic tensioning member 37 on one side. If the metal sheet metal is tilted during movement, it will touch the testing plates 38 on both sides. When the testing plates 38 are subjected to pressure, they will be detected by the pressure sensors 36, thereby sending an error signal to the control terminal of the device and stopping the device to prevent the machine from jamming and improve the service life of the device.

[0029] Each of the multiple support plates 14 has a limiting rod 29 inside, and a scraper 27 is slidably arranged on the outside of each of the multiple limiting rods 29. Each of the multiple support plates 14 has a first elastic tensioning member 28 inside, and one end of each of the multiple first elastic tensioning members 28 is connected to the scraper 27. The scraper 27 slides against the lower pressure roller 12. By setting the scraper 27, the lower pressure roller 12 can be scraped against the outer surface of the lower pressure roller 12 during rotation, thus cleaning the lower pressure roller 12 and preventing dust and impurities from being pressed into the surface of the metal sheet by the lower pressure roller 12, which would affect the processing quality.

[0030] Further reference Figure 2 , Figure 3 and Figure 4 Each of the support plates 14 has a collection block 30 on its bottom end face, and each of the collection blocks 30 has a dust suction port 31 on its outer surface. The dust suction ports 31 face the outer surface of the support plate 14. One end of the collection block 30 is connected to the outer surface of the body 10 with a second connecting pipe 35. The second connecting pipe 35 is connected to the inside of the collection block 30. A collection box 34 is connected to the bottom of the second connecting pipe 35. A blower 33 is connected to one side of the collection box 34. By starting the blower 33, an adsorption effect is formed inside the collection box 34, and the air inside the collection block 30 is adsorbed through the second connecting pipe 35. This allows the dust suction ports 31 to adsorb the impurities scraped off by the scraper 27 and transport the impurities into the collection box 34 through the second connecting pipe 35 for collection. The collection box 34 is equipped with a filter plate that can filter dust to prevent dust from entering the blower 33 and damaging its internal structure.

[0031] Further reference Figure 2 , Figure 3 and Figure 4 Each of the multiple support plates 14 has an open preheating chamber 23, with one end facing the lower pressure roller 12. Each preheating chamber 23 contains a heating element 24, and each heating element 24 has a sinking connection groove 25 below it. Each sinking connection groove 25 has a return groove 26 on one side. A first connecting pipe 32 is located on the outer surface of the machine body 10 on one side of each sinking connection groove 25, and the first connecting pipe 32 is connected to a blower 33. When the blower 33 is started, it draws out the contents of the collection box 34. Air is discharged into the interior of the first connecting pipe 32 and transported to the interior of the preheating chamber 23 through the first connecting pipe 32. At the same time, the heating element 24 is activated to heat the air entering the preheating chamber 23. Part of the heated air enters the interior of the return groove 26, forming a swirling airflow that heats the interior of the support plate 14, facilitating the preheating treatment of the plate and improving its plasticity. Meanwhile, part of the airflow flows to the opening of the preheating chamber 23, and the heated gas ejected from the opening of the preheating chamber 23 preheats the lower pressure roller 12, improving the rolling effect of the lower pressure roller 12.

The control of the driving component by the similar detection components and the related detection methods and specific circuit relationships of each detection component can all adopt conventional electrical control technology. As long as the corresponding motion relationship can be completed and its beneficial effect can be achieved in this solution, it can be implemented.
