Description

Technical Field

[0001] This utility model relates to the field of pipe production equipment, specifically to a plate edge grinding and conveying machine. Background Technology

[0002] In the steel pipe manufacturing industry, the surface treatment of the steel strip edges is a crucial step affecting weld quality. In existing technologies, steel strips are often not subjected to specialized edge rust removal treatment before welding, resulting in residual oxide scale, rust, and other contaminants on the edge surface. These residues can easily cause weld defects during welding, such as porosity and slag inclusions, leading to failure in ultrasonic testing.

[0003] Currently, the main rust removal methods used in the industry include chemical pickling, sandblasting, and manual grinding. However, these methods have significant drawbacks: chemical pickling easily causes environmental pollution and is difficult to control corrosion in localized areas of the board edges; sandblasting equipment is bulky and energy-intensive, making it difficult to integrate into continuous production lines; and manual grinding is inefficient and cannot guarantee uniform rust removal. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a board edge grinding conveyor, including a conveyor frame for conveying boards and a grinding mechanism disposed on the conveyor frame. The grinding mechanism is used to grind the two side edge surfaces of the conveyed board.

[0006] The grinding mechanism includes drive motors symmetrically arranged on both sides of the conveyor frame perpendicular to the material conveying direction, and grinding wheels connected to the output shafts of the drive motors. The grinding wheels contact the edges of the material to grind the edges under the drive of the drive motors.

[0007] Optionally, the board edge grinding conveyor also includes an adjustment component connected to the conveyor frame. The drive motors are respectively set on the conveyor frame through the corresponding adjustment components, and the adjustment components can adjust the corresponding drive motors to move closer to or further away from the board.

[0008] Optionally, the adjustment assembly includes a guide rail connected to the transmission frame, a slide block slidably connected to the guide rail, and a drive component that drives the slide block to move linearly back and forth on the guide rail. The drive motor is mounted on the slide block, and the extension direction of the guide rail is perpendicular to the material transmission direction.

[0009] Optionally, the guide rail includes a base and a guide groove formed on the top surface of the base, the extension direction of the guide groove being perpendicular to the conveying direction of the plate, and the bottom of the slide block being formed in a sliding section that slides into the guide groove.

[0010] Optionally, the drive unit includes a lead screw extending in a direction parallel to the guide rail, and a slide is threadedly connected to the lead screw.

[0011] Optionally, the drive includes a turntable fixedly connected to the lead screw so that it can be manipulated to rotate the lead screw.

[0012] Optionally, a shaft seat is provided on the transmission frame, and the lead screw is rotatably connected to the shaft seat.

[0013] Optionally, the grinding wheel includes two mutually perpendicular grinding surfaces, which are used to abut against the side and top surfaces of the board, respectively.

[0014] Optionally, multiple sets of grinding mechanisms are provided, and the multiple sets of grinding mechanisms are arranged at intervals on the conveyor frame along the conveying direction of the plate.

[0015] Optionally, the grinding wheel can be detachably connected to the shaft of the drive motor.

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] Generally, reference Figure 1 The transmission frame 1 in this utility model mainly includes two opposing support frames 101, a plurality of transmission rollers 102 disposed between the two support frames 101, a motor 103 driving the transmission rollers 102 to rotate, and a transmission chain 104 connecting the plurality of transmission rollers 102 and the output end of the transmission motor 103. The plurality of transmission rollers 102 are all configured with their axial direction perpendicular to the length direction of the support frame 101, and the plurality of transmission rollers 102 are equally spaced along the length direction of the support frame 101.

[0023] The support frame 101 is provided with a plurality of support legs 106 at intervals along its length. The opposing support legs 106 of two support frames 101 are connected by a connecting strip plate 105 to enhance the stability of the transmission frame 1.

[0024] The length of the conveyor roller 102 must be greater than the width of the plate (such as steel strip).

[0025] In this invention, multiple transmission rollers 102, driven by a transmission motor 103, can carry the plate and transmit it along the length of the support frame 101.

[0026] refer to Figure 1 and Figure 2 The board edge grinding conveyor of this utility model includes a conveyor frame 1 for conveying boards and a grinding mechanism 2 disposed on the conveyor frame 1. The grinding mechanism 2 is used to grind the two sides of the board edge surface of the conveyed board.

[0027] The grinding structure includes drive motors 201 symmetrically arranged on both sides of the transmission frame 1 along the direction perpendicular to the material transmission, and grinding wheels 202 connected to the output shaft of the drive motors 201. The grinding wheels 202 contact the edge of the material so that the edge of the material can be ground under the drive of the drive motors 201.

[0028] The grinding motor 103 rotates in the same direction as the sheet material conveying direction (i.e., the rotation direction of the aforementioned transfer rollers). Furthermore, the output speed of the grinding motor 103 is set to be significantly higher than the conveying speed of the conveyor frame. It is understood that the grinding wheel 202 driven by the grinding motor 103 can form a sliding motion along the conveying direction with the corresponding sheet edge. This sliding motion can grind the sheet material edge, thereby removing adhering substances and processing burrs from the edge of the sheet material, achieving a precision grinding effect.

[0029] It should be noted that the sliding friction force applied by the grinding wheel 202 to the board is always lower than the static friction force between the board and the conveyor frame drive roller group, thereby avoiding abnormal board displacement and ensuring effective grinding of the board edge by the grinding wheel 202. Of course, the rotation direction of the grinding motor 103 can also be set to be opposite to the conveying direction of the board.

[0030] In some embodiments, the board edge grinding conveyor may also include an adjustment component 3 connected to the conveyor frame 1. The drive motors 201 are respectively set on the conveyor frame 1 through the corresponding adjustment components 3, and the corresponding drive motors 201 can be adjusted by the adjustment components 3 to move closer to or away from the board, thereby adapting to boards of different widths.

[0031] In some embodiments, the adjustment component 3 includes a guide rail 301 connected to the transmission frame 1, a slide block 302 slidably connected to the guide rail 301, and a drive member that drives the slide block 302 to move linearly and reciprocally on the guide rail 301. The drive motor 201 is disposed on the slide block 302, and the extension direction of the guide rail 301 is perpendicular to the transmission direction of the plate.

[0032] In this utility model, the operator can control the grinding wheel 202 on the drive motor 201 to move closer to or further away from the edge of the board by manipulating the drive component according to the specific size of the board.

[0033] Among them, reference Figure 1 The guide rail 301 can be fixedly connected to the support frame 101 of the transmission frame 1.

[0034] The guide rail 301 in this utility model can have any suitable structure, see reference. Figure 2 In one embodiment, the guide rail 301 may include a base 3011 and a guide groove 3012 formed on the top surface of the base 3011. The extension direction of the guide groove 3012 is perpendicular to the transmission direction of the plate. The bottom of the slide 302 forms a sliding section 3021 that slides in cooperation with the guide groove 3012.

[0035] The guide groove 3012 has symmetrically arranged limiting grooves 306 extending perpendicular to the conveying direction on both sides of its side walls. The sliding section 3021 has strip-shaped protrusions 3022 on both sides of its side walls that can slide within the corresponding limiting grooves 306, thereby applying anti-detachment constraint to the slide block 302 in the vertical direction.

[0036] In some embodiments, the driving component may include a lead screw 303 extending in a direction parallel to the guide rail 301, and a slide 302 threadedly connected to the lead screw 303. Rotating the lead screw 303 causes the slide 302 to move along the extension direction of the guide rail 301. Of course, in other embodiments, other driving components with linear motion output, such as electric cylinders, may also be used.

[0037] The first end 3031 of the lead screw 303 can pass through the wall surface of the base 3011 opposite to the support frame 101 along a direction perpendicular to the transmission direction, and extend to be rotatably connected to the support frame 101. The second end 3032 of the lead screw 303 can extend in the opposite direction of the extension direction of the first end 3031 to the outside of the base 3011, so as to facilitate connection with the drive component.

[0038] In some embodiments, the drive unit may further include a turntable 305 fixedly connected to the lead screw 303 so as to be manipulated to rotate the lead screw 303. Of course, in other embodiments, a servo motor 103 may be used to drive the lead screw 303 to rotate.

[0039] In some embodiments, reference Figure 2 A bearing seat 4 is provided on the transmission frame 1, and the lead screw 303 is rotatably connected to the bearing seat 4.

[0040] The guide groove 3012 can be configured to pass through the base 3011 perpendicular to the transmission direction at one end facing the support frame 101. The bearing 4 can be located in the guide groove 3012, and the first end 3031 of the lead screw 303 passes through the base 3011, the guide groove 3012 and the sliding section 3021 of the slide block 302 and is rotatably connected to the bearing 4.

[0041] The bearing seat 4 may include a cylindrical base with a rotating hole on the top surface of the base, and the lead screw 303 is rotatably connected to the rotating hole.

[0042] In this invention, threads may be provided only on the portion of the lead screw 303 that is located within the guide groove 3012. That is, threads may not be provided on the side of the lead screw 303 that contacts the base 3011 or the portion that contacts the shaft seat 4.

[0043] In some embodiments, the grinding wheel 202 includes two grinding surfaces 2021 that are perpendicular to each other. The two grinding surfaces 2021 are used to abut against the side and top surfaces of the board respectively, so as to enable grinding of the two surfaces of the board edge.

[0044] The grinding wheel 202 can be set as a grinding wheel or a wire brush.

[0045] In some embodiments, the grinding mechanism 2 is provided with multiple sets, and the multiple sets of grinding structures are arranged at intervals on the transmission frame 1 along the transmission direction of the plate.

[0046] In this utility model, the grinding structure is provided in two sets, and the two sets of grinding mechanisms 2 can be located at both ends of the transmission frame 1 respectively.

[0047] In some embodiments, the grinding wheel 202 is detachably connected to the shaft 203 of the drive motor 201 to facilitate the replacement of a damaged grinding wheel 202.

[0048] Among them, a fixed sleeve 5 is fitted on the rotating shaft 203, and the end face of the fixed sleeve 5 abuts against the grinding wheel 202.

[0049] Among them, reference Figure 2 A threaded hole is provided on the outer wall of the rotating shaft 203. The threaded hole is located in front of the fixed sleeve 5 in the direction toward the support frame 101, and a bolt is provided in the threaded hole. The minimum distance between the bolt and the end face of the fixed sleeve 5 can be equal to or slightly greater than the thickness of the grinding wheel 202, so that the grinding wheel 202 is detachably clamped between the bolt and the fixed sleeve 5.

[0050] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. To avoid unnecessary repetition, the present invention will not describe various possible combinations separately. However, these simple variations and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
