[0002] This application claims priority to Chinese Patent Application No. 202410674721.4, filed on May 29, 2024, entitled "An Edge Grinding System for Plate-to-Edge Assembly", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of sheet metal processing equipment, and more particularly to an edge grinding system for feeding sheets. Background Technology

[0004] Boards are flat, rectangular building material panels made to standard sizes, used in the construction industry as components for walls, ceilings, or floors. With the rapid development of the construction industry, the demand for boards is increasing, and these boards generally require processing before use.

[0005] Currently, most sheet metal processing uses roller conveyors. During transport, the sheets inevitably deviate from the conveying direction to some extent. Since the sheets require edge grinding, the edges need to be aligned with the grinding equipment. Existing technology typically uses a cylinder on one side of the roller conveyor to lift it, bringing the sheet's edge close to the other side for alignment. However, the cylinder occupies a large space and limits the stroke of its extension rod, making existing devices unsuitable for sheets of various sizes. Furthermore, the force required to lift the roller conveyor is significant, making it easy for the sheet to fall off and be damaged. Summary of the Invention

[0006] The purpose of this invention is to provide a grinding system for feeding plates to solve the problems of existing devices being unable to adapt to plates of various sizes due to structural limitations, and the problem that plates easily fall off the roller conveyor during the lifting process.

[0007] To achieve this objective, the present invention adopts the following technical solution:

A plurality of top blocks are spaced apart on the inside of the connecting rod. The adjusting drive drives the top blocks to extend out from the gap between the top edge rollers through the connecting rod, or drives the top blocks to retract from the gap between the top edge rollers through the connecting rod.

[0019] The first positioning sensor and the second positioning sensor are respectively mounted on the frame, and both the first positioning sensor and the second positioning sensor are electrically connected to the adjustment drive component to detect whether both ends of the plate are tightly abutting the edge retaining mechanism.

[0020] In the edge grinding system for the feed plate, the other end of the movable frame extends outward to form an extension frame, which is equipped with an extension roller assembly.

[0023] The lifting drive component is fixed to the movable frame; the transmission component is connected to the lifting drive component and is hinged to the movable frame to drive the auxiliary roller assembly to extend from between the conveyor belt units or to retract the auxiliary roller assembly from between the conveyor belt units.

[0024] In the edge grinding system for the feed plate, the transmission assembly includes a push rod, a linkage arm, a first linkage rod, a first transmission bent arm, a first lifting seat, a second linkage rod, a second transmission bent arm, and a second lifting seat.

[0025] One end of the push rod is connected to the lifting drive component, and the other end of the push rod is hinged to one end of the linkage arm. The first linkage rod is rotatably mounted on one end of the movable frame along the Y-axis. The linkage arm is connected to the first linkage rod.

The lifting drive component is located between the first lifting seat and the second lifting seat.

[0026] The second linkage rod is rotatably mounted on one end of the movable frame along the Y-axis, one end of the second transmission arm is hinged to the second lifting seat, and the other end of the second transmission arm is connected to the second linkage rod.

[0027] In the edge grinding system for the feed plate, the frame further includes a leveling assembly, which includes a connecting seat and a leveling screw. The top of the connecting seat is provided with a threaded hole, and one end of the leveling screw is threadedly connected to the threaded hole. When the movable frame is placed horizontally, the top of the leveling screw abuts against the other end of the movable frame.

It achieves edge alignment through the cooperation of the frame, lifting mechanism, and edge-blocking mechanism. At the same time, the pressure plate mechanism tightly presses the board against the conveyor belt mechanism; the board slides by its own weight to achieve edge alignment and can be transferred to the edge grinding machine, ensuring the conveying benchmark and keeping the edge grinding line and positioning edge on the same straight line. This is beneficial for the board to carry out the next edge grinding process, making the edge grinding more precise and effectively ensuring the accuracy and reliability of the board conveying, thus meeting the needs of board edge grinding processing.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] Please refer to Figures 1-7. The present invention provides an edge grinding system for feeding plates, including an edge grinding machine a and a feeding worktable b. The feeding worktable b is located at the feeding end of the edge grinding machine a. The feeding worktable b includes a frame 1, a conveyor belt mechanism 2, a lifting mechanism 3, an edge blocking mechanism 4, and a pressure plate mechanism 5.

[0045] The frame 1 includes a movable frame 11 and a fixed frame 12; the fixed frame 12 is hinged to the movable frame 11.

[0046] The conveyor belt mechanism 2 is mounted on the movable frame 11 and is used to convey the sheet metal.

[0047] The lifting mechanism 3 is disposed between the movable frame 11 and the fixed frame 12, and is used to drive the movable frame 11 to tilt and lift about the hinge point between the fixed frame 12 and the movable frame 11 as the rotation axis. The conveying direction of the conveyor belt mechanism 2 is parallel to the axis of the rotation axis.

[0048] The edge-blocking mechanism 4 is disposed at one end of the movable frame 11. When the movable frame 11 is tilted and raised, the edge-blocking mechanism 4 is used to prevent the plate from sliding out of the movable frame 11 and to align the side edge of the plate.

[0049] The pressing plate mechanism 5 is located above the conveyor belt mechanism 2 and is used to press the plate against the conveyor belt mechanism 2.

[0050] The feeding workbench b is located at the feed end of the edge grinding machine a and includes a conveyor belt mechanism 2, a lifting mechanism 3, an edge-blocking mechanism 4, and a pressure plate mechanism 5. The conveyor belt mechanism 2 transports the sheet metal into the feeding workbench b and delivers the sheet metal after edge alignment. The lifting mechanism 3 is used to lift the movable frame 11, causing the movable frame 11 to rotate around the hinge point between the fixed frame 12 and the movable frame 11, causing the movable frame 11 to tilt and thus move the sheet metal closer to the edge-blocking mechanism 4. Subsequently, the side edge of the sheet metal is pressed tightly against the edge-blocking mechanism 4. The pressure plate mechanism 5 presses the sheet metal tightly against the conveyor belt mechanism 2, ensuring that the conveyor belt mechanism 2 can still transport the sheet metal while the lifting mechanism 3 lifts the movable frame 11, thus improving edge alignment efficiency and ensuring that the position of each sheet metal is relatively fixed. The feeding workbench b can deliver the sheet metal after edge alignment through the conveyor belt mechanism 2, and the edge grinding operation can then be performed on the sheet metal.

[0051] When edge alignment is required, the conveyor belt mechanism 2 feeds the sheet material into the feeding workbench b, the pressing plate mechanism 5 presses the sheet material tightly against the conveyor belt mechanism 2, and the lifting mechanism 3 lifts the movable frame 11. The movable frame 11 rotates around the hinge point between the fixed frame 12 and the movable frame 11, so that an angle is formed between the movable frame 11 and the fixed frame 12. The sheet material is on the conveyor belt mechanism 2 on the movable frame 11, and the sheet material slides towards the edge retaining mechanism 4, so that the side edge of the sheet material is tightly against the edge retaining mechanism 4. Then, the lifting mechanism 3 drives the movable frame 11 to reset, so that the movable frame 11 is parallel to the horizontal plane, and the conveyor belt mechanism 2 then sends out the sheet material that has completed edge alignment.

[0052] The feeding workbench b has a simple structure and is easy to operate. It achieves edge alignment through the cooperation of the frame 1, lifting mechanism 3 and edge blocking mechanism 4. At the same time, the pressure plate mechanism 5 presses the board tightly against the conveyor belt mechanism 2, and the board slides by its own weight to achieve edge alignment. It can be transferred to the edge grinding machine a to ensure the conveying benchmark and keep the edge grinding line and positioning edge on the same straight line. This is beneficial for the board to carry out the next edge grinding process, making the edge grinding more accurate and effectively ensuring the accuracy and reliability of the board conveying, thus meeting the needs of the board edge grinding process.

[0053] Specifically, the pressure plate mechanism 5 includes a support frame 51, a lifting drive component 52, and a pressure plate frame 53; the support frame 51 is mounted on the machine frame 1, the fixed end of the lifting drive component 52 is disposed on the support frame 51, and the driving end of the lifting drive component 52 is connected to the pressure plate frame 53, so that the pressure plate frame 53 is suspended above the conveyor belt mechanism 2; the pressure plate frame 53 is provided with two or more pressure plate roller groups 54 along the X-axis direction, and the pressure plate roller groups 54 are arranged side by side; the lifting drive component 52 drives the pressure plate frame 53 to move closer to or away from the conveyor belt mechanism 2.

[0054] The pressure plate roller assembly 54 consists of multiple pressure plate rollers arranged along the X-axis, and the pressure plate rollers are rotatably mounted on the bottom of the pressure plate frame 53. While ensuring that the sheet material is tightly attached to the conveyor belt mechanism 2, it reduces the friction between the sheet material and the pressure plate frame 53, so that the sheet material can be conveyed simultaneously while it is tightly attached to the conveyor belt mechanism 2, thereby improving the conveying efficiency.

[0055] The lifting drive component 52 can refer to existing telescopic cylinders or drive motors. In a specific embodiment of the present invention, two pressure plate frames 53 and four lifting drive components 52 are provided; the driving ends of the lifting drive components 52 are arranged downwards; the two pressure plate frames 53 are arranged side by side, and the two ends of the pressure plate frames 53 are respectively connected to the driving ends of the lifting drive components 52. Optionally, the pressure plate mechanism 5 is also provided with guide rods, one end of which is connected to the pressure plate frame 53, and the other end of which is slidably connected to the support frame 51; the guide rods enable the pressure plate frame 53 to move in the vertical direction, preventing the pressure plate frame 53 from moving in other directions and improving the structural stability of the pressure plate mechanism 5. In a preferred embodiment, one pressure plate frame 53 is equipped with two lifting drive components 52 and two guide rods, and the four corners of the pressure plate frame 53 are respectively connected to the lifting drive components 52 or guide rods, which can further provide structural stability.

[0056] Furthermore, the edge-blocking mechanism 4 includes a top edge frame 41 and a plurality of top edge rollers 42;

[0057] The top edge frame 41 is connected to one end of the movable frame 11, the top edge roller 42 is rotatably mounted on the top edge frame 41, and a plurality of the top edge rollers 42 are spaced apart along the X-axis direction.

[0058] The sheet material is pressed tightly against the side wall of the top edge roller 42, which is rotatably mounted on the top edge frame 41. Therefore, when the movable frame 11 is in the raised state, the conveyor belt mechanism 2 can continue to operate, allowing the sheet material to move along the top edge roller 42 on the top edge frame 41. With this structure, the friction between the sheet material and the edge retaining mechanism 4 is reduced when the movable frame 11 is in the raised state, allowing it to continue moving and improving conveying efficiency.

[0059] Furthermore, the pressure plate mechanism 5 also includes a top edge adjustment assembly, which includes an adjustment connecting seat 551, an adjustment drive component 552, a limiting guide rod 553, a connecting rod 554, a first positioning sensor 555, a second positioning sensor 556, and multiple top blocks 557.

[0060] The adjusting connecting seat 551 is connected to the side of the fixed frame 12 near the side guard mechanism 4. The adjusting driving member 552 is disposed on the outside of the adjusting connecting seat 551. The driving end of the adjusting driving member 552 passes through the adjusting connecting seat 551 and is connected to the outside of the connecting rod 554. One end of the limiting guide rod 553 is connected to the outside of the connecting rod 554, and the other end of the limiting guide rod 553 passes through the adjusting connecting seat 551 and is slidably connected to the adjusting connecting seat 551. A plurality of top blocks 557 are spaced apart on the inside of the connecting rod 554. The adjusting driving member 552 drives the top blocks 557 to extend out from the gap between the top edge rollers 42 through the connecting rod 554, or drives the top blocks 557 to retract from the gap between the top edge rollers 42 through the connecting rod 554.

[0061] The first positioning sensor 555 and the second positioning sensor 556 are respectively disposed on the frame 1, and both the first positioning sensor 555 and the second positioning sensor 556 are electrically connected to the adjustment drive component 552 to detect whether both ends of the plate are tightly abutting the edge retaining mechanism 4.

[0062] The first positioning sensor 555 and the second positioning sensor 556 detect whether both ends of the side of the board are tightly abutting the edge-blocking mechanism 4, thereby determining whether the side of the board is completely attached to the top edge roller 42. When the side of the board is attached to the top edge roller 42 on the side of the first positioning sensor 555, the first positioning sensor 555 receives a sensing signal; similarly, when the side of the board is attached to the top edge roller 42 on the side of the second positioning sensor 556, the second positioning sensor 556 receives a sensing signal. If both the first positioning sensor 555 and the second positioning sensor 556 receive sensing signals, it means that the side of the board is completely attached to the top edge roller 42; if either the first positioning sensor 555 or the second positioning sensor 556 fails to receive a sensing signal, it means that one end of the side of the board is not attached to the corresponding top edge roller 42.

[0063] Subsequently, the drive end of the adjusting drive component 552 extends, driving the connecting rod 554 to move closer to the top edge roller 42, causing the top block 557 to extend out from the gap between the top edge rollers 42, thereby lifting the plate; immediately afterward, the drive end of the adjusting drive component 552 retracts, driving the connecting rod 554 to move away from the top edge roller 42, causing the top block 557 to retract out from the gap between the top edge rollers 42, and the side of the plate to re-contact the top edge roller 42.

[0064] By adopting the above structure, the position of the plate can be adjusted a second time, so that the side of the plate is in close contact with the top roller 42, thereby further ensuring the accuracy and reliability of plate conveying.

[0065] Preferably, the other end of the movable frame 11 extends outward to form an extension frame 13, and the extension frame 13 is provided with an extension roller assembly 131.

[0066] The existing boards have significant differences in width and length, and all four sides of the boards require edge grinding. Therefore, an extension frame 13 is provided; the extension frame 13 can extend the load-bearing length of the movable frame 11. When edge grinding is required on the sides along the length of the board, one end of the board along the width direction is pressed against the top edge roller 42, and the other end along the width direction is located on the extension roller assembly 131 of the extension frame 13. The extension roller assembly 131 serves to assist in conveying, reduce friction between the bottom surface of the board and the extension frame 13, facilitate board conveying, and improve conveying speed.

[0067] The extension roller assembly 131 is composed of multiple extension rollers combined along the X-axis direction, and all extension rollers are rotatably mounted on the extension frame 13.

[0068] Furthermore, it also includes an auxiliary sliding mechanism 6, which includes a lifting drive 61, a transmission assembly 62, a roller frame 63, and a plurality of auxiliary roller groups 64;

[0069] The conveyor belt mechanism 2 includes multiple conveyor belt units 21, which are arranged side by side along the Y-axis on the movable frame 11; the roller frame 63 is connected to the transmission assembly 62 and is located below the movable frame 11; multiple auxiliary roller groups 64 are arranged on the roller frame 63 and are located in the gap between two adjacent conveyor belt units 21.

[0070] The lifting drive component 61 is fixed to the movable frame 11; the transmission component 62 is connected to the lifting drive component 61 and is hinged to the movable frame 11 to drive the auxiliary roller group 64 to extend from between the conveyor belt units 21, or to retract the auxiliary roller group 64 from between the conveyor belt units 21.

[0071] The conveyor belt unit 21 can refer to the existing conveyor belt structure. The conveyor belt unit 21 conveys the sheet material, effectively ensuring the accuracy and reliability of the sheet material conveying.

[0072] The lifting drive 61 drives the roller frame 63 to move upward or downward through the transmission assembly 62, thereby causing the auxiliary roller group 64 on the roller frame 63 to extend or retract from the gap between the conveyor belt units 21.

[0073] With the above structure, an auxiliary roller assembly 64 is provided between the conveyor belt units 21. When alignment is required, the lifting drive 61 drives the auxiliary roller assembly 64 to extend from the gap between the conveyor belt units 21, lifting the sheet material so that it can slide more easily toward the edge-blocking mechanism 4. This prevents excessive friction between the sheet material and the conveyor belt unit 21, which could prevent it from sliding toward the edge-blocking mechanism 4 and causing the sheet material to fail to align. During the sheet material conveying process, the lifting drive 61 drives the auxiliary roller assembly 64 to retract from the gap between the conveyor belt units 21, preventing the auxiliary roller assembly 64 from lifting the sheet material and causing the conveyor belt unit 21 to be unable to convey the sheet material.

[0074] Furthermore, the transmission assembly 62 includes a push rod 621, a linkage arm 622, a first linkage rod 623, a first transmission bent arm 624, a first lifting seat 625, a second linkage rod 626, a second transmission bent arm 627, and a second lifting seat 628.

[0075] One end of the push rod 621 is connected to the lifting drive member 61, and the other end of the push rod 621 is hinged to one end of the linkage arm 622. The first linkage rod 623 is rotatably mounted on one end of the movable frame 11 around the X-axis. The linkage arm 622 is connected to the first linkage rod 623. The first lifting seat 625 and the second lifting seat 628 are respectively disposed at one end of the roller frame 63. The lifting drive member 61 is located between the first lifting seat 625 and the second lifting seat 628. One end of the first transmission bent arm 624 is hinged to the first lifting seat 625, and the other end of the first transmission bent arm 624 is connected to the first linkage rod 623.

[0076] The second linkage rod 626 is rotatably mounted on one end of the movable frame 11 around the X-axis. One end of the second transmission arm 627 is hinged to the second lifting seat 628, and the other end of the second transmission arm 627 is connected to the second linkage rod 626.

[0077] The auxiliary roller assembly 64 includes two roller shafts arranged side by side, and multiple guide rollers are spaced apart on the roller shafts. The guide rollers are rotatably mounted on the roller shafts. The roller shafts are mounted on the roller frame 63.

[0078] Referring to Figure 6, the lifting drive component 61 is specifically a drive motor. When it is necessary to lift the auxiliary roller assembly 64, the lifting drive component 61 pushes, causing the push rod 621 to extend forward. The push rod 621 drives the linkage arm 622 to rotate clockwise around the axis of the first linkage rod 623, and drives the first linkage rod 623 to rotate clockwise. This causes the first linkage rod 623 to drive the first transmission bent arm 624 to rotate clockwise, thereby causing the first transmission bent arm 624 to lift the first lifting seat 625, which in turn lifts the roller frame 63. The roller frame 63 then moves upward. The roller frame 63 drives the auxiliary roller assembly 64 to extend out from the gap between the conveyor belt units 21; at the same time, the roller frame 63 drives the second lifting seat 628 to move upward, thereby driving the second transmission arm 627 to rotate clockwise around the axis of the second linkage rod 626; the second lifting seat 628 and the second transmission arm 627 are linked with the first transmission arm 624 and the first lifting seat 625 through the roller frame 63, so that the roller frame 63 is evenly stressed, thereby ensuring that the roller frame 63 moves upward as a whole, and avoiding the roller frame 63 from tilting to one side, which would affect the guiding effect on the plate.

[0079] When the auxiliary roller assembly 64 needs to be retracted, the lifting drive 61 drives the push rod 621 to retract backward. The push rod 621 drives the linkage arm 622 to rotate counterclockwise around the axis of the first linkage rod 623, and drives the first linkage rod 623 to rotate counterclockwise. This causes the first linkage rod 623 to drive the first transmission arm 624 to rotate counterclockwise, which in turn causes the first transmission arm 624 to lower the first lifting seat 625. This causes the first lifting seat 625 to drive the roller frame 63 to retract, and the auxiliary roller assembly 64 retracts from the gap between the conveyor belt units 21.

[0080] Specifically, the frame 1 further includes a leveling assembly 14, which includes a connecting seat and a leveling screw; the top of the connecting seat is provided with a threaded hole, and one end of the leveling screw is threadedly connected to the threaded hole. When the movable frame 11 is placed horizontally, the top of the leveling screw abuts against the other end of the movable frame 11; the bottom of the connecting seat is fixed to one end of the fixed frame 12.

[0081] The leveling component 14 can refer to the existing adjusting screw. By controlling the length of the leveling screw extending from the threaded hole, the tilt angle of the movable frame 11 when it is in a horizontal position can be adjusted to achieve the purpose of leveling. When the movable frame 11 is in a horizontal position, the leveling component 14 can play the role of assisting in supporting the movable frame 11.

[0082] Specifically, the lifting mechanism 3 includes a cylinder 31 and an air tank 32; the fixed end of the cylinder 31 is disposed on the fixed frame 12, and the driving end of the cylinder 31 is hinged to one end of the movable frame 11; the air tank 32 is connected to the cylinder 31 and is used to provide compressed gas to the cylinder 31.

[0083] The air tank 32 provides compressed gas to the cylinder 31, causing the drive end of the cylinder 31 to extend or retract. Controlling the exhaust or intake of air from the air tank 32 controls the extension or retraction of the cylinder 31. This design is simple in structure, easy to operate, and effectively ensures the stability of the movable frame 11 during lifting. In one specific embodiment of the invention, two cylinders 31 are provided, respectively located on both sides of the air tank 32. By simultaneously extending or retracting the two cylinders 31, the movable frame 11 rotates, making it more stable during lifting and preventing swaying due to uneven force distribution.

[0084] Specifically, the fixed frame 12 is provided with a hinge seat 121, and the bottom of the movable frame 11 is hinged to the hinge seat 121.

[0085] In one specific embodiment of the present invention, the fixed frame 12 is hinged to the movable frame 11 via a hinge seat 121. By adjusting the leveling component 14, the length of the leveling component 14 is adapted to the height of the hinge seat 121, thereby keeping the movable frame 11 horizontal. During normal conveying of the sheet metal, the movable frame 11 is parallel to the horizontal plane, preventing the conveyor belt mechanism 2 from accidentally shifting the position of the sheet metal due to angular deviation during conveying.

[0086] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
