Description

Technical Field

[0001] This invention relates to the field of sheet metal folding technology, and more specifically, to a high-efficiency folding mechanism for sandwich panels. Background Technology

[0002] A high-efficiency edge-folding mechanism for sandwich panels is a device used in the processing of sandwich panels, including rock wool sandwich panels and glass wool sandwich panels. Its main function is to bend the edges of the sandwich panels to improve their appearance and quality. Among the disclosed technologies, Chinese Patent Publication No. CN210876936U discloses an edge-folding mechanism for integrated metal panels. While existing edge-folding machines can apply adhesive using a glue applicator and cold press to cold press the composite metal panel and insulation board to ensure composite quality, they cannot fold the composite metal panel itself. This new edge-folding mechanism uses a power mechanism including a driving hydraulic cylinder hinged to the edge-folding frame. The piston rod end of the driving hydraulic cylinder is hinged to the bottom of the edge-folding plate. This equipment is reasonably designed and easy to use, folding the composite metal panel to facilitate the mechanized composite of integrated metal panels and ensure the quality of the composite. However, this edge-folding mechanism also has the following drawbacks. When the aforementioned folding mechanism folds the sandwich panel, it only folds one side of the sandwich panel, making it difficult to simultaneously bend the sandwich panel to different lengths on both sides. This results in the sandwich panel needing to bend at different lengths repeatedly before bending, making the bending process more time-consuming and labor-intensive. If there are any dimensional problems with the folding, it needs to be returned to the factory for refolding, resulting in low folding efficiency. Therefore, a more efficient folding mechanism for sandwich panels is needed. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency folding mechanism for sandwich panels.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency folding mechanism for sandwich panels, comprising a guide frame plate, wherein a linkage screw is connected inside the guide frame plate, and a linkage positioning folding assembly is provided on the outer wall of the linkage screw; The linkage folding assembly includes a first threaded linkage sleeve block and a second threaded linkage sleeve block arranged sequentially from right to left on the outer wall of the linkage screw. One end of the linkage screw extends to the outside of the guide frame plate and is coaxially connected to a reduction drive motor. A sliding support plate is fixedly connected to one side of both the second threaded linkage sleeve block and the first threaded linkage sleeve block. A positioning sensor is installed on one side of the sliding support plate, and a folding length sensing block is welded to the top of the inner wall of the sliding support plate. A support sleeve block is fixedly connected to one side of the positioning sensor. A connecting bracket is provided on the outer wall of the positioning sensor and on the side adjacent to the support sleeve block. A folding length sensor for sensing the distance to the folding length sensing block is connected to one side of the connecting bracket. Both the first threaded linkage sleeve block and the second threaded linkage sleeve block are threadedly connected to the linkage screw. The two threads on the outer surface of the linkage screw are opposite and symmetrically arranged. The reduction drive motor is fixedly connected to the guide frame plate, and the first threaded linkage sleeve block and the guide frame plate are rotatably connected via a bearing. Both the positioning sensor and the folding length sensor are fixedly connected to the connecting bracket. The rear of the positioning sensor and the folding length sensor are on the same vertical plane.

[0005] Preferably, a positioning bracket is welded to one side of the guide frame plate, a controller is fixedly connected to the front of the positioning bracket, a sliding plate is welded to the bottom end of the sliding support plate, and a guide slide frame is slidably connected to the outer wall of the sliding plate near its bottom end.

[0006] According to the above technical solution, the controller starts the reduction drive motor to drive the linkage screw to rotate. The linkage screw drives the first threaded linkage block to move to the left under the action of the thread, while the second threaded linkage block moves to the right under the action of the thread. The second threaded linkage block and the reduction drive motor drive the two sliding support plates to move respectively. The distance between the folding length sensing block and the folding length sensor increases, extending the bending length on both sides of the sandwich panel.

[0007] Preferably, two linkage frames are welded to the top of the guide frame plate, and a positioning linkage component is installed inside the linkage frame plate; The positioning linkage assembly includes an adjusting screw rotatably mounted inside the linkage frame plate. The outer wall of the adjusting screw is provided with a threaded sleeve support block that slidably connects to the linkage frame plate. One end of the adjusting screw extends to the outside of the linkage frame plate and is coaxially connected to a reduction drive motor. A sleeve plate is welded to one side of the threaded sleeve support block. A hydraulic cylinder is fixedly connected to the top of the sleeve plate. The output end of the hydraulic cylinder extends below the sleeve plate and is fixedly connected to a bending template. Guide slide rods are fixedly connected to the top of the bending template and at positions on both sides of the hydraulic cylinder. Both guide slide rods are vertically slidably connected to the sleeve plate. One side of the sleeve plate and near... A connecting slider is installed at its central position. A guide pillar is vertically slidably connected inside the connecting slider. A connecting compression ring is fixedly connected to the outer wall of the guide pillar near its top. A connecting linkage block is welded to one side of the outer wall of the connecting compression ring. A guide post is vertically slidably connected inside the connecting linkage block. A return spring is fixedly connected between the connecting compression ring and the connecting slider. An adjusting screw is threadedly connected to a threaded connecting block. Both the adjusting screw and the threaded connecting block are made of stainless steel. The connecting slide plate and the connecting linkage block are fixedly connected to the connecting slider. The cross-sectional area of ​​the top of the guide post is larger than the cross-sectional area of ​​its bottom.

[0008] According to the above technical solution, the bending length data of both sides of the sandwich panel is set on the controller. The reduction transmission motor is started to drive the adjusting screw to rotate inside the linkage frame plate. The adjusting screw drives the threaded sleeve support block to slide to the right along the inside of the linkage frame plate. The sleeve slide causes the sleeve slider to drive the support sleeve block to move the positioning sensor to the right. At the same time, the positioning sensor drives the connecting bracket to move the bending length sensor. The bending length sensor senses the distance of the bending length sensing block. When the distance set by the controller is reached, the reduction transmission motor drive is turned off by the controller. At the same time, the positioning sensor can sense the side edge of the sandwich panel to ensure that the protruding part of the side edge of the sandwich panel is in contact with the position sensed by the positioning sensor. The hydraulic cylinder is started to drive the bending template to press downward. The bending template simultaneously drives the two guide slides to move downward along the inside of the sleeve slide. At the same time, the sleeve extrusion ring can squeeze the return spring. The return spring is compressed on the guide support, and the extended part of the sandwich panel is precisely and efficiently bent.

[0009] Preferably, a pusher cylinder is fixedly installed on the inner wall of the positioning bracket, and the pusher end of the pusher cylinder is connected to a linkage discharge assembly; The linked discharge assembly includes a pushing and squeezing block fixedly installed at the pushing end of the pushing electric cylinder. A concave hinge block is welded to one side of the pushing and squeezing block near its top. A linkage shaft is rotatably connected inside the concave hinge block. A rotary reduction motor is coaxially driven to one end of the linkage shaft. The rotary reduction motor is fixedly connected to the concave hinge block. A sleeve hook plate is welded to the outer wall of the linkage shaft at a position inside the concave hinge block. A pressing electric cylinder is fixedly connected to the top of the sleeve hook plate near its middle position. The pushing end of the pressing electric cylinder extends to below the sleeve hook plate and is fixedly connected to a pressing support column. A pressing support plate is welded to the bottom end of the pressing support column. A sandwich plate is installed between the pressing support plate and the positioning bracket.

[0010] According to the above technical solution, the starting electric cylinder drives the lowering support column to slide upward along the inside of the sleeve hook plate. At the same time, the lowering support column drives the lowering support plate to move upward. The lowering support plate is no longer pressed against the top position of the sandwich panel. The starting electric cylinder drives the pushing extrusion block to move to the right. The linkage shaft drives the sleeve hook plate to move to the right. The sleeve hook plate drives the sandwich panel to slide along the surface of the positioning bracket. After the sandwich panel moves to the right, the starting rotary reduction motor drives the linkage shaft to move upward. The linkage shaft drives the sleeve hook plate to rotate upward, and the sandwich panel is removed.

[0011] The technical effects and advantages of this invention are as follows: 1. This invention uses a linkage positioning folding assembly to drive a reduction drive motor to rotate a linkage screw. The linkage screw drives the first threaded linkage sleeve block to move to the left under the action of the thread, while the second threaded linkage sleeve block moves to the right under the action of the thread. The sliding support plate drives the folding length sensing block to move to the left, increasing the distance between the folding length sensing block and the folding length sensor. The edges of both sides of the sandwich panel can extend beyond the right side of the sliding support plate, enabling precise extension bending of different bending lengths on both sides of the sandwich panel simultaneously. This makes bending more time-saving and labor-saving, and effectively improves the folding efficiency of the sandwich panel. 2. This invention uses a positioning linkage component to start a reduction transmission motor that drives an adjusting screw to rotate inside the linkage frame plate. The adjusting screw drives the threaded sleeve support block to slide to the right along the inside of the linkage frame plate. The sleeve slide causes the sleeve slider to drive the support sleeve block to move the positioning sensor to the right. The positioning sensor drives the connecting bracket to move the folding length sensor. The folding length sensor senses the distance of the folding length sensing block. When the distance is sensed by the controller, the bending template is pressed against the sandwich panel located on the extension part of the sliding support plate. It can accurately sense the distance of the extension part of the sandwich panel and the bending length distance of the sandwich panel through the positioning sensor and the folding length sensor. Based on different data, it can accurately position the sandwich panel and effectively improve the folding efficiency when folding the sandwich panel on both sides simultaneously. 3. This invention uses a linkage discharge assembly to activate the pressing electric cylinder, which drives the pressing support to slide upward along the inside of the sleeve hook plate. The pressing support plate is no longer pressed against the top of the sandwich panel. The activation of the pushing electric cylinder drives the pushing extrusion block to move to the right. The concave hinge block causes the linkage shaft to move the sleeve hook plate to the right. The sleeve hook plate drives the sandwich panel to slide along the surface of the positioning bracket. The activation of the rotary reduction motor drives the linkage shaft to move upward. The sleeve hook plate moves upward and is removed. This invention can automatically expand and remove sandwich panels with synchronous folding on both sides. During the removal process, not only is the sandwich panel stably discharged, but it can also ensure synchronous discharge from both sides, effectively improving the discharge efficiency. Through the interaction of the above-mentioned multiple functions, the sandwich panel is first extended precisely at different bending lengths on both sides simultaneously. Then, the distance of the extended part of the sandwich panel is accurately sensed by the positioning sensor and the folding length sensor before folding. Finally, the sandwich panel with simultaneous folding on both sides is automatically expanded and material is picked up. In summary, the sandwich panel can be automatically extended on both sides according to different folding lengths. After extension, the folding position is double-checked before folding, which effectively improves the folding efficiency of the sandwich panel. Attached Figure Description

The cross-sectional area of ​​the top of the guide post 29 is larger than the cross-sectional area of ​​its bottom.

[0025] In some embodiments, as shown in the appendix Figure 6-8 As shown, a push cylinder 31 is fixedly installed on the inner wall of the positioning bracket 12, and the push end of the push cylinder 31 is connected to a linkage discharge assembly; The linkage discharge assembly includes a pushing and pressing block 32 fixedly installed at the pushing end of the pushing electric cylinder 31.

[0026] The working principle of the high-efficiency folding mechanism for the sandwich panel in this embodiment is as follows: Firstly, when the present invention performs side positioning and folding, the controller 13 starts the reduction drive motor 5 to drive the linkage screw 2 to rotate. The linkage screw 2 drives the first threaded linkage sleeve 3 to move to the left under the action of the thread, while the second threaded linkage sleeve 4 moves to the right under the action of the thread. The second threaded linkage sleeve 4 and the reduction drive motor 5 respectively drive the two sliding support plates 6 to move. The sliding support plates 6 drive the folding length sensing block 7 to move to the left. The distance between the folding length sensing block 7 and the folding length sensor 11 increases, and the right side of the two sides of the sandwich panel 16 can extend out of the right side of the sliding support plate 6. Secondly, when calibrating the bending distance, the present invention sets the bending length data on both sides of the sandwich panel 16 on the controller 13, starts the reduction transmission motor 24 to drive the adjusting screw 18 to rotate inside the linkage frame plate 17, the adjusting screw 18 drives the threaded sleeve support block 19 to slide to the right along the inside of the linkage frame plate 17, and at the same time the threaded sleeve support block 19 drives the sleeve slide plate 20 to cause the sleeve slider 25 to drive the support sleeve block 9 to move the positioning sensor 8 to the right. At the same time, the positioning sensor 8 drives the connecting bracket 10 to move the folding length sensor 11. The folding length sensor 11 senses the distance of the folding length sensing block 7. When the distance set by the controller 13 is sensed, the controller 13 shuts off the drive of the reduction transmission motor 24. At the same time, the positioning sensor 8 can sense the side edge of the sandwich panel 16 to ensure that the edge of the sandwich panel 16 is properly aligned. The side protrusion part is in contact with the position sensed by the positioning sensor 8. The hydraulic cylinder 21 is activated to drive the bending template 23 to press downward. At the same time, the bending template 23 drives the two guide slide rods 22 to move downward along the inside of the sleeve slide plate 20. The bending template 23 drives the positioning sensor 8 to move the support sleeve block 9 downward. The support sleeve block 9 drives the guide pillar 26 to move downward along the inside of the sleeve slide block 25. At the same time, the guide pillar 26 drives the sleeve linkage block 28 to move vertically downward along the outer wall of the guide pillar 29. At the same time, the sleeve extrusion ring 27 can extrude the return spring 30. The return spring 30 is compressed on the guide pillar 26. In this way, the positioning sensor 8 can move downward while the bending template 23 presses on the sandwich plate 16 located on the extension part of the sliding support plate 6, and the extension part of the sandwich plate 16 is precisely bent. Finally, during material discharge, the present invention activates the pressing electric cylinder 37 to drive the pressing support column 38 to slide upward along the inside of the sleeve hook plate 36. At the same time, the pressing support column 38 drives the pressing support plate 39 to move upward. The pressing support plate 39 is no longer pressed against the top position of the sandwich plate 16. The pushing electric cylinder 31 is activated to drive the pushing extrusion block 32 to move to the right. The pushing extrusion block 32 drives the concave hinge block 33 to cause the linkage shaft 34 to drive the sleeve hook plate 36 to move to the right. The sleeve hook plate 36 drives the sandwich plate 16 to slide along the surface of the positioning bracket 12. After the sandwich plate 16 moves to the right, the rotary reduction motor 35 is activated to drive the linkage shaft 34 to move upward. The linkage shaft 34 drives the sleeve hook plate 36 to rotate upward. The sleeve hook plate 36 no longer limits the sandwich plate 16, and the sleeve hook plate 36 can be moved upward and removed.
