Description

Technical Field

[0001] This utility model relates to the field of sheet metal production technology, and in particular to a dual-axis servo centering feeder for a leveling machine used in the production of sound-absorbing sheet metal. Background Technology

[0002] In the production process of sound-absorbing sheet materials, the materials need to be leveled to ensure their flatness and quality. Traditional leveling machine feeding devices usually adopt a simple fixed structure or a relatively crude adjustment method. For example, some old-fashioned feeding devices rely solely on manual adjustment of the baffle to roughly determine the position and width range of the material. This method is not only inefficient, but also makes it difficult to accurately control the position and stress of the material. In addition, some existing devices use sliding friction when conveying materials, which can easily lead to severe wear on the edges of the materials, affecting product quality. At the same time, they have poor adaptability to materials of different widths and cannot be flexibly adjusted. When processing narrow or wide materials, problems such as material displacement and warping can easily occur. Moreover, in the pressing stage, there is a lack of precise pressure control mechanism, which can easily damage the fragile sound-absorbing sheet materials due to excessive pressure.

[0003] A search revealed that the document with publication number "CN212704089U" states that "this utility model relates to the field of leveling machine technology and discloses a leveling machine with high feeding stability. It includes a feeding mechanism, which comprises a horizontal plate, two sliders disposed on the horizontal plate, two strip-shaped holes on the horizontal plate, a positioning element, and a locking bolt. The sliders are provided with positioning pins passing through the strip-shaped holes. The positioning element is threadedly connected to the positioning pins. A first hole is horizontally opened on the positioning element, and a second hole is horizontally opened on the positioning pin. When the positioning element is pressed against the horizontal plate, the first hole is directly opposite the second hole, and the locking bolt passes through both the first and second holes." During use, the feeding mechanism with high feeding stability is stable, and the position and direction of the steel plate feeding can be continuously controlled, resulting in high feeding stability.

[0004] However, traditional feeding devices are difficult to adapt to plates of different widths and cannot flexibly adjust the spacing of auxiliary rollers, resulting in the equipment being able to process only plates of specific specifications, which limits production efficiency and the scope of application of the equipment. At the same time, the lack of precise limiting and clamping mechanisms makes the plates prone to deviation and warping during the conveying process, affecting the accuracy and consistency of subsequent processing.

[0005] Therefore, we provide a dual-axis servo centering feeder for a leveling machine used in the production of sound-absorbing sheet metal to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a dual-axis servo centering feeder for a leveling machine used in the production of sound-absorbing sheet metal, aiming to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A dual-axis servo centering feeder for a leveling machine used in the production of sound-absorbing sheet metal includes a base. An auxiliary support plate is mounted on the upper surface of the base. A bullseye wheel is fixedly connected to the upper end of the auxiliary support plate. A second connecting frame is arranged above the bullseye wheel. A second motor is mounted on the left end of the second connecting frame. A limit plate is mounted on the inner surface of the second connecting frame. A width adjustment component is arranged on the inner side of the limit plate. The width adjustment component includes a movable connecting rod installed on the inner side of the limit plate. An auxiliary roller is rotatably connected to the inner side of the upper end of the movable connecting rod. A pressing component is fixedly connected to the upper surface of the limit plate. The pressing component includes a fixed connecting rod fixedly connected to the upper surface of the limit plate. A top plate is fixedly connected to the upper end of the fixed connecting rod.

[0008] As a further description of the above technical solution: A first connecting frame is installed on the inner side of the auxiliary support plate. A first motor is installed on the right end of the first connecting frame. A first lead screw is connected to the output end of the first motor via a key. A movable block is provided on the surface of the first lead screw. A sliding rod is provided below the movable block. A first fixing plate is provided above the movable block.

[0009] As a further description of the above technical solution: The first motor drives the moving block to move left and right through the first lead screw. The front and rear ends of the moving block are provided with right-angle connecting frames, and the moving block is fixedly connected to the second connecting frame through the right-angle connecting frames. Bullseye wheels are evenly distributed on the surface of the first fixed plate.

[0010] As a further description of the above technical solution: A conveying block is provided on the inner side of the second connecting frame. A second lead screw is connected to the output end of the second motor via a flat key. A second fixing plate is provided above the conveying block. The second lead screw passes through the conveying block. The second motor drives the conveying block to move along the axial direction of the second lead screw through the second lead screw.

[0011] As a further description of the above technical solution: A rotating lead screw is installed on the inner side of the movable connecting rod. A rotating motor is connected to the left end of the rotating lead screw with a flat key. There are two sets of movable connecting rods, and the movable connecting rods are arranged symmetrically. The rotating motor drives the movable connecting rods to move towards each other by rotating the lead screw.

[0012] As a further description of the above technical solution: A connecting plate is fixedly connected to the upper left side of the top plate. A sliding groove is provided on the upper surface of the top plate. Slide tracks are provided on both the left and right sides of the sliding groove. A slider is slidably connected to the inner side of the slide track.

[0013] As a further description of the above technical solution: A third lead screw is provided on the inner side of the slider, and a driving cylinder is fixedly connected to the upper end of the slider. A pressing plate is fixedly connected to the telescopic end of the driving cylinder. The pressing plate corresponds to the size and position of the conveying block. The third lead screw is driven by a moving motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By setting up a width adjustment component and driving a rotating screw with a rotating motor, the moving connecting rod can move in opposite directions, flexibly adjusting the spacing of the auxiliary rollers to adapt to different widths of plates, improving the versatility of the equipment. The auxiliary rollers roll in contact with the plate, converting sliding friction into rolling friction, significantly reducing edge wear of the plate and ensuring production quality. At the same time, the screw drive can precisely fit the two sides of the plate to form a stable limit, preventing conveying deviation. Combined with the efficient transmission of the servo motor, the response is rapid and the force is symmetrical and uniform, avoiding plate deformation and adapting to the processing needs of brittle plates such as sound-absorbing sheets.

[0015] By setting up a clamping component, the slider moves laterally along the slide rail under the drive of the third lead screw. The lateral position of the clamping plate can be adjusted according to the size and position of the plate to ensure that it corresponds with the conveying block. The drive cylinder can precisely control the clamping force by adjusting the air pressure to avoid excessive pressure damaging the sound-absorbing sheet and other vulnerable plates, while also preventing slippage during conveying. The size and position of the clamping plate correspond to the conveying block, so that the plate is subjected to symmetrical force from top to bottom, avoiding warping and displacement during conveying. Working synchronously with the conveying component, it ensures the stability of conveying, reduces rigid collisions, and improves the smoothness of operation and service life.

A slide bar 8 is provided below the moving block 7. A first fixing plate 9 is provided above the moving block 7. The first connecting frame 4 is installed on the inner side of the auxiliary support plate 2. After the first motor 5 at the right end is started, the output end drives the first lead screw 6 to rotate via the key. The moving block 7 on the surface of the first lead screw 6 moves along the direction of the slide bar 8 under the action of the lead screw thread.

After the rotating motor 1604 is started, its output end drives the rotating lead screw 1603 to rotate through the flat key. The two sets of symmetrically arranged movable connecting rods 1601 move towards each other along the axial direction of the rotating lead screw 1603 under the action of the lead screw thread. The auxiliary roller 1602 on the inner side of its upper end moves synchronously with the movable connecting rod 1601 until it fits against both sides of the plate, limiting the plate and preventing it from shifting.

[0024] Furthermore, a connecting plate 1703 is fixedly connected to the upper left side of the top plate 1702. A groove 1704 is provided on the upper surface of the top plate 1702.

The third lead screw 1707 is driven by a moving motor. After the third lead screw 1707 drives the slider 1706 to move along the slide 1705 to the corresponding position above the plate, the drive cylinder 1708 at the upper end of the slider 1706 is activated, and the telescopic end extends downward, driving the pressing plate 1709 to descend until the pressing plate 1709 is in close contact with the plate on the conveying block 13, completing the pressing action. The pressing plate 1709 corresponds to the size and position of the conveying block 13 to ensure uniform force.

[0026] Working principle: In use, firstly, the first motor 5 at the right end of the first connecting frame 4 is started. Its output end drives the first lead screw 6 to rotate via a flat key, causing the moving block 7 on the surface of the first lead screw 6 to move laterally along the slide bar 8 under the action of the thread. The right-angle connecting frame at the front and rear ends drives the second connecting frame 10 to move synchronously, realizing the overall position adjustment of the upper structure. The bullseye wheel 3 rolls with the second connecting frame 10 to assist in the movement. Then, the second motor 11 at the left end of the second connecting frame 10 is started. Its output end drives the second lead screw 14 to rotate via a flat key. The second lead screw 14, which passes through the conveyor block 13, drives the conveyor block 13 to move axially. The second fixed plate 15 above moves synchronously, conveying the plate to the processing area. At the same time, the width adjustment component is activated. The rotating motor 1604 of the 16th generation drives the rotating screw 1603 to rotate via a flat key, causing two sets of symmetrical moving connecting rods 1601 to move towards each other along the rotating screw 1603. The auxiliary rollers 1602 on the inner side of the upper end move synchronously until they are in contact with both sides of the board to complete the limit and prevent deviation. Finally, the third screw 1707 drives the slider 1706 to move along the slide rail 1705 of the top plate 1702 to the corresponding position above the board. The drive cylinder 1708 at the upper end of the slider 1706 is activated, and the telescopic end drives the pressing plate 1709 to descend, making close contact with the board on the conveying block 13 to complete the pressing and ensure the stability of the board during processing. This completes the use of a dual-axis servo centering feeder for a leveling machine for the production of sound-absorbing sheet material.
