[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] 1 to 5 , the present invention provides a plate edge alignment mechanism for edge grinding and feeding plates, comprising a frame 1 , a conveyor belt mechanism 2 , a lifting mechanism 3 and a top edge mechanism 4 ;

[0042] The frame 1 includes a movable frame 11, a lifting rod 12, and a fixed frame 13; the movable frame 11 is located above the fixed frame 13, and the top of the fixed frame 13 is hinged to the bottom of the movable frame 11; one end of the lifting rod 12 is connected to one end of the movable frame 11, and the other end of the lifting rod 12 is connected to one end of the fixed frame 13;

[0043] The conveyor belt mechanism 2 is provided on the movable frame 11 and is used for conveying the plates;

[0044] The lifting mechanism 3 is provided between the movable frame 11 and the fixed frame 13, and is used to drive the movable frame 11 to rotate with the hinge between the fixed frame 13 and the movable frame 11 as the rotation axis;

[0045] The top edge mechanism 4 is disposed at one end of the movable frame 11 . When the movable frame 11 is lifted, the side edge of the plate is pressed against the top edge mechanism 4 .

[0046] The plate edge alignment mechanism includes a conveyor belt mechanism 2, a lifting mechanism 3 and a top edge mechanism 4. The plate is conveyed by the conveyor belt mechanism 2 so that the plate can enter the plate edge alignment mechanism and the plate that has completed edge alignment is sent out; the lifting mechanism 3 is used to lift the movable frame 11, so that the movable frame 11 rotates with the hinge between the fixed frame 13 and the movable frame 11 as the rotation axis, so that the movable frame 11 tilts, thereby driving the plate to approach the top edge mechanism 4; then, the side edge of the plate is tightly against the top edge mechanism 4, so that the position of each plate is relatively fixed, and the plate edge alignment mechanism can send the plate that has completed edge alignment out through the conveyor belt mechanism 2, and the plate can be edged.

[0047] When the plate needs to be aligned, the conveyor belt mechanism 2 feeds the plate into the plate alignment mechanism, and the lifting mechanism 3 lifts the movable frame 11. The movable frame 11 rotates with the hinge between the fixed frame 13 and the movable frame 11 as the rotation axis. At the same time, the lifting rod 12 extends upward, so that an angle appears between the movable frame 11 and the fixed frame 13. There is a plate on the conveyor belt mechanism 2 on the movable frame 11. The plate slides toward the top edge mechanism 4, so that the side of the plate is tightly against the top edge mechanism 4. Subsequently, the lifting mechanism 3 drives the movable frame 11 to reset, making the movable frame 11 parallel to the horizontal plane. The lifting rod 12 shortens downward, and the conveyor belt mechanism 2 then sends out the plate with the completed edge alignment. The lifting rod 12 is used to maintain the structural stability between the movable frame 11 and the fixed frame 13, and to limit the rotation range of the movable frame 11 to prevent the plate from falling off the conveyor belt mechanism 2 due to excessive rotation angle.

[0048] The plate edge alignment mechanism has a simple structure and is easy to operate. The edge alignment operation is achieved through the cooperation of the frame 1, the lifting mechanism 3 and the top edge mechanism 4, ensuring the conveying reference, which is beneficial to the next step of plate edge grinding processing, effectively ensuring the accuracy and reliability of plate conveying, and meeting the needs of plate edge grinding processing.

[0049] Specifically, the conveyor belt mechanism 2 includes a plurality of conveyor belt units 21 , and the plurality of conveyor belt units 21 are arranged side by side on the movable frame 11 along the X-axis.

[0050] The conveyor belt unit 21 can refer to the existing conveyor belt structure. The conveyor belt unit 21 conveys the plates, effectively ensuring the accuracy and reliability of the plate transportation.

[0051] Specifically, it also includes an auxiliary sliding mechanism 5, which includes a lifting drive member 51, a transmission assembly 52, a roller frame 53 and a plurality of roller groups 54;

[0052] The roller frame 53 is disposed below the movable frame 11 , and the plurality of roller groups 54 are disposed on the roller frame 53 , and the roller groups 54 are located in the gap between two adjacent conveyor belt units 21 ;

[0053] The lifting drive member 51 is fixed to the movable frame 11; the transmission assembly is in transmission connection with the lifting drive member 51, and the transmission assembly is hinged to the movable frame 11 to drive the roller group 54 to extend between the conveyor belt units 21, or to retract the roller group 54 from between the conveyor belt units 21.

[0054] The lifting drive member 51 drives the roller frame 53 to move upward or downward through the transmission assembly 52 , thereby driving the roller set 54 on the roller frame 53 to extend from or retract into the gap between the conveyor belt units 21 .

[0055] With the above structure, roller assemblies 54 are provided between the conveyor belt units 21. When alignment is required, the lifting drive 51 drives the roller assemblies 54 to extend from the gaps between the conveyor belt units 21, lifting the sheet material, making it easier for the sheet material to slide toward the edge-lifting mechanism 4. This prevents excessive friction between the sheet material and the conveyor belt units 21, which would prevent the sheet material from sliding toward the edge-lifting mechanism 4 and causing it to be unable to align with the edge. During the sheet material conveying process, the lifting drive 51 drives the roller assemblies 54 to retract from the gaps between the conveyor belt units 21, preventing the roller assemblies 54 from lifting the sheet material and causing the conveyor belt units 21 to be unable to convey the sheet material.

[0056] Specifically, the transmission assembly 52 includes a push rod 521, a linkage arm 522, a first linkage rod 523, a first transmission bent arm 524, a first lifting seat 525, a second linkage rod 526, a second transmission bent arm 527 and a second lifting seat 528;

[0057] One end of the push rod 521 is connected to the lifting drive member 51, and the other end of the push rod 521 is hinged to one end of the linkage arm 522. The first linkage rod 523 is rotatably assembled on one end of the movable frame 11 along the Y axis. The linkage arm 522 is connected to the first linkage rod 523. The first lifting seat 525 and the second lifting seat 528 are respectively provided at one end of the roller frame 53. The lifting drive member 51 is located between the first lifting seat 525 and the second lifting seat 528. One end of the first transmission bent arm 524 is hinged to the first lifting seat 525, and the other end of the first transmission bent arm 524 is connected to the first linkage rod 523.

[0058] The second linkage rod 526 is rotatably assembled along the Y axis on one end of the movable frame 11 . One end of the second transmission arm 527 is hinged to the second lifting seat 528 , and the other end of the second transmission arm 527 is connected to the second linkage rod 526 .

[0059] 4 , the lifting drive member 51 is specifically a driving motor. When the roller assembly 54 needs to be raised, the lifting drive member 51 pushes the push rod 521 to extend forward, and the push rod 521 drives the linkage arm 522 to rotate clockwise with the axis of the first linkage rod 523 as the rotation axis, and drives the first linkage rod 523 to rotate clockwise, so that the first linkage rod 523 drives the first transmission bent arm 524 to rotate clockwise, and then the first transmission bent arm 524 lifts the first lifting seat 525, so that the first lifting seat 525 lifts the roller frame 53; the roller frame 53 moves upward and drives the roller assembly 54 extends out from the gap between the conveyor belt units 21; at the same time, the roller frame 53 drives the second lifting seat 528 to move upward, thereby driving the second transmission bent arm 527 to rotate clockwise with the axis of the first linkage rod 523 as the rotation axis, so that the movable frame 11 is in a lifted state; the second lifting seat 528 and the second transmission bent arm 527 are linked with the first transmission bent arm 524 and the first lifting seat 525 through the roller frame 53, so that the roller frame 53 is evenly stressed, thereby ensuring that the roller frame 53 moves upward as a whole, and preventing the roller frame 53 from tilting to one side, affecting the guiding effect on the plate.

[0060] When it is necessary to retract the roller group 54, the lifting drive member 51 drives the push rod 521 to retract backward, and the push rod 521 drives the linkage arm 522 to rotate counterclockwise with the axis of the first linkage rod 523 as the rotation axis, and drives the first linkage rod 523 to rotate counterclockwise, so that the first linkage rod 523 drives the first transmission bent arm 524 to rotate counterclockwise, and then the first transmission bent arm 524 lowers the first lifting seat 525, so that the first lifting seat 525 drives the roller frame 53 to retract, and the roller group 54 retracts from the gap between the conveyor belt units 21, so that the movable frame 11 is in a horizontal position.

[0061] Specifically, the roller assembly 54 includes two roller shafts 541 arranged side by side. The roller shafts 541 are provided with a plurality of guide rollers 542 at intervals. The guide rollers 542 are rotatably assembled on the roller shafts 541 . The roller shafts 541 are provided on the roller frame 53 .

[0062] In one embodiment of the present invention, a roller assembly 54 includes two roller shafts 541 disposed side by side, with a plurality of guide rollers 542 coaxially disposed on the roller shafts 541. The guide rollers 542 are capable of rotating along the axis of the roller shafts 541. When the movable frame 11 is raised, the plate can be pressed against the top edge mechanism 4 along the inclined angle.

[0063] Optionally, the frame 1 further includes a leveling assembly 12, comprising a connecting base and a leveling screw. The connecting base has a threaded hole at the top, one end of the leveling screw is rotatably connected to the other end of the movable frame 11, and the other end of the leveling screw is threadedly connected to the threaded hole. The bottom of the connecting base is fixed to one end of the fixed frame 13. The leveling assembly 12 can refer to existing adjustment screws. By controlling the length of the leveling screw extending from the threaded hole, the tilt angle of the movable frame 11 when 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 assembly 12 can also serve to provide auxiliary support for the movable frame 11.

[0064] Furthermore, the lifting mechanism 3 includes a cylinder 31 and a gas tank 32; the fixed end of the cylinder 31 is arranged on the fixed frame 13, and the driving end of the cylinder 31 is hinged to one end of the movable frame 11; the gas tank 32 is connected to the cylinder 31 for providing compressed gas to the cylinder 31.

[0065] The gas 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 gas from the gas tank 32 controls the extension or retraction of the cylinder 31. This simple structure and convenient operation effectively ensure the stability of the movable frame 11 during lifting. In one embodiment of the present invention, two gas cylinders 31 are provided, one on each side of the gas tank 32. The simultaneous extension or retraction of the two cylinders 31 allows the movable frame 11 to rotate, making the movable frame 11 more stable during lifting and preventing swinging due to uneven force.

[0066] Furthermore, the cylinder 31 is tilted outward. With the above structure, the angle of the movable frame 11 changes more slowly when it is lifted, so that the plate can slide slowly toward the top edge mechanism 4, avoiding the movable frame 11 being lifted too quickly, causing the plate to quickly hit the top edge mechanism 4 and cause damage to the top edge mechanism 4 or the plate.

[0067] Specifically, the top edge mechanism 4 includes a top edge plate 41 and a plurality of top edge rollers 42; the top edge plate 41 is connected to one end of the movable frame, and the top edge plate 41 is provided with a receiving groove, the notch of the receiving groove faces inward, and the plurality of top edge rollers 42 are rotatably assembled in the receiving groove; the top edge rollers 42 are arranged at intervals along the X-axis direction.

[0068] The plate is pressed against the side wall of the top roller 42, and the top roller 42 is rotatably assembled in the receiving groove. Therefore, when the movable frame 11 is in the raised state, the conveyor belt mechanism 2 can continue to operate, so that the plate moves along the top roller 42 on the top plate 41. With the above structure, the plate can continue to move when the movable frame 11 is in the raised state, thereby improving the conveying efficiency.

[0069] In a specific embodiment of the present invention, the fixed frame 13 is provided with an articulated seat 131 , the height of the articulated seat 131 is the same as the length of the lifting rod 12 in the retracted state; the bottom of the movable frame 11 is hinged to the articulated seat 131 .

[0070] The fixed frame 13 is hinged to the movable frame 11 through the hinge seat 131, and the height of the hinge seat 131 is the same as the length of the lifting rod 12 in the retracted state; so that when the plate edge-to-edge mechanism is normally conveying the plate, the movable frame 11 is parallel to the horizontal plane, avoiding the accidental displacement of the position of the plate due to the angle deviation when the conveyor belt mechanism 2 is conveying the plate.

[0071] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are intended to be encompassed within the scope of the claims of this application.
