Description

Technical Field

[0001] This invention relates to the field of dual-track buffer technology, specifically a dual-track buffer compatible with multiple sizes. Background Technology

[0002] Dual-track buffer machines, as key equipment in the material conveying and temporary storage process, are widely used in automated production lines, logistics sorting, electronic component assembly and other fields. Their core function is to achieve efficient material transfer and temporary storage, connect the production rhythm of the preceding and following processes, and avoid production line stagnation caused by differences in process speed. However, dual-track buffer machines on the market generally have technical pain points and are difficult to meet diverse production needs.

[0003] Taking the "Dual-track High-speed PCB Buffer Machine" with application number CN202121775863.8 as an example, the shifting and storage device of the equipment includes one fixed buffer track and three movable buffer tracks. The fixed buffer track and the movable buffer track are provided with a transverse storage belt assembly on opposite sides, and the assembly is equipped with a first gear. The crossbeam of its receiving and transfer device is correspondingly provided with one fixed transport track and three movable transport tracks. Both the fixed transport track and the movable transport track are composed of an upper conveyor belt assembly and a lower conveyor belt assembly. Both types of conveyor belt assemblies are provided with a second gear adapted to the first gear.

[0004] From an advantage perspective, the equipment, with its "1 fixed + 3 movable" track configuration, can improve work efficiency and transmission speed through its dual-track design, and can also buffer workpiece boards of different specifications by adjusting the positions of the movable buffer track and the movable transport track, thus possessing high flexibility. However, from a disadvantage perspective, the equipment can only adapt to extra-large boards by using track avoidance, lacks a multi-dimensional adjustment structure, and is prone to jamming when dealing with PCBs of irregular sizes, making it difficult to meet the diverse production needs under complex working conditions.

[0005] Based on this, this solution proposes "a dual-track buffer machine compatible with multiple sizes" to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a dual-track buffer machine compatible with multiple sizes, in order to solve the problem mentioned in the background art that existing market devices lack multi-dimensional adjustment structures and are prone to jamming when dealing with PCBs of irregular sizes.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dual-track buffer machine compatible with multiple sizes, comprising a support base, a first fixed cabinet, a second fixed cabinet, a third fixed cabinet, and a fourth lead screw;

[0008] A buffer mechanism is provided above the support base. The buffer mechanism includes a fourth fixed cabinet, a third motor, a first guide rod, a first drive frame, a connecting plate, a fifth motor, a buffer strip, a limiting pad, and a second lead screw. The first guide rod is located on the side of the fourth fixed cabinet, the first drive frame is installed above the first guide rod, the second lead screw is installed on the side of the first drive frame, the third motor is installed above the second lead screw, the connecting plate is installed above the first drive frame, and the buffer strip and limiting pad are installed below the connecting plate.

[0009] As a preferred technical solution of the present invention, the upper surface of the bearing base is fixedly connected to the positioning blocks, the positioning blocks are symmetrically distributed in a total of twelve, and the lower surface of the bearing base is provided with heat dissipation grooves, the heat dissipation grooves are in a straight line structure, the left side of the center line of the bearing base is fixedly connected to the second side plate, and the right side of the center line of the bearing base is fixedly connected to the first side plate, the first side plate and the second side plate have the same structure.

[0010] Using the above technical solution, the twelve symmetrically distributed positioning blocks on the upper surface of the support base can provide precise installation positioning for components such as the upper buffer mechanism and the first fixed cabinet, avoiding assembly misalignment and significantly improving the overall assembly stability of the equipment; the straight heat dissipation groove opened on the lower surface of the support base can quickly dissipate the heat inside the base, preventing the hidden circuits and connectors inside the base from aging due to high temperature, thus extending the service life of the support base; the second side plate on the left side of the center line of the support base has the same structure as the first side plate on the right side, which can not only achieve standardized production to reduce mold development costs, but also facilitate component interchange during later maintenance, reducing the difficulty of maintenance operations.

[0011] As a preferred technical solution of the present invention, the first fixed cabinet is connected to the top of the support base by positioning blocks and positioning holes. The third side plate is fixed to the side of the first fixed cabinet by bolts, and the surface of the third side plate is opened with the same heat dissipation groove as the support base. The second fixed cabinet and the third fixed cabinet are arranged in sequence on the side of the first fixed cabinet. The shell structures of the first fixed cabinet, the second fixed cabinet and the third fixed cabinet are the same, and positioning holes are opened at both the top and bottom of the first fixed cabinet. There are four positioning holes in total, which are distributed in a rectangular shape.

[0012] Using the above technical solution, the support base is connected to the first fixed cabinet by engaging with the positioning block and positioning hole, allowing for assembly and disassembly without complex tools, significantly improving equipment assembly efficiency and facilitating subsequent disassembly and transportation. The third side plate of the first fixed cabinet, which is bolted to the side, has the same heat dissipation grooves as the support base, which can form a vertical linkage with the base's heat dissipation structure, enhancing the heat dissipation effect of core components such as motors and lead screws inside the first fixed cabinet and preventing overheating of components that could cause equipment shutdown. The first, second, and third fixed cabinets have identical shell structures, enabling standardized production, reducing the investment in molds for different specifications of components, and allowing for interchangeability of components. If a fixed cabinet malfunctions, it can be directly replaced, shortening the maintenance cycle. The four rectangular positioning holes at the top and bottom of the first fixed cabinet ensure precise alignment during installation, preventing tilting and further improving the overall structural stability of the equipment.

[0013] As a preferred technical solution of the present invention, an eighth motor is fixedly connected inside the first fixed cabinet, the output shaft of the eighth motor is fixedly connected to a third lead screw, the third lead screw is rotatably connected to a second drive frame, the second drive frame is slidably connected to a first conveyor frame, and a third guide rod is slidably connected above the first conveyor frame;

[0014] Using the above technical solution, the output shaft of the eighth motor fixed inside the first fixed cabinet is connected to the third lead screw, which is rotatably connected to the second drive frame. This allows the second drive frame to drive the first conveyor frame to slide, achieving linear and precise adjustment of the position of the first conveyor frame. It can be flexibly adjusted according to the material size, laying the foundation for size compatibility of dual-rail conveying. The third guide rod slidably connected above the first conveyor frame can limit the sliding trajectory of the first conveyor frame, preventing the conveyor frame from shifting left or right when moving, ensuring the stability of the material conveying process, and preventing the material from falling.

[0015] As a preferred technical solution of the present invention, a ninth motor is fixedly connected above the first conveyor frame, and a reversing wheel is fixedly connected to the output shaft of the ninth motor. There are two reversing wheels symmetrically distributed. A first belt is fitted on the outer side of the reversing wheel, and a tensioning wheel is fitted below the first belt. The tensioning wheel shaft is rotatably connected to a tensioning shaft, and a bearing is configured at the connection between the tensioning shaft and the tensioning wheel. A counterweight bolt is slidably connected to the side of the tensioning shaft, and a counterweight plate is threadedly connected to the bottom of the counterweight bolt.

[0016] Using the above technical solution, the output shaft of the ninth motor fixed above the first conveyor frame is connected to two symmetrically distributed reversing wheels. The first belt fitted on the outside of the reversing wheels can transmit motor power in a balanced manner, avoiding transmission jamming caused by uneven force on one side and ensuring the stability of power transmission. The end of the tension wheel shaft fitted below the first belt is rotatably connected to the tensioning shaft, and a bearing is configured at the connection to reduce friction loss, reduce the wear rate of components, and extend the service life of the tensioning structure. The bottom of the counterweight bolt slidably connected to the side of the tensioning shaft is threadedly connected to the counterweight plate, which can flexibly adjust the pressure of the tension wheel on the first belt. When the material is heavy, it can be tightened to prevent slippage, and when the material is light, it can be loosened to prevent over-tightening and damage, always maintaining the belt transmission efficiency and adapting to the conveying needs of materials of different weights.

[0017] As a preferred embodiment of the present invention, a second conveyor with the same structure is arranged symmetrically to the first conveyor;

[0018] Using the above technical solution, a second conveyor with the same structure is configured symmetrically at the first conveyor frame, which directly realizes the dual-rail conveying function. Compared with single-rail conveying, the efficiency is doubled. It can convey two batches of materials at the same time, and can also provide synchronous support and conveying of large-sized materials at both ends. The two conveyor frames have the same structure, which can share production molds and maintenance parts, reducing production and maintenance costs. When adjusting synchronously, it can ensure the consistency of the movement of the two rails and avoid the material from shifting due to the difference in speed or position of the two rails.

[0019] As a preferred embodiment of the present invention, the buffer plate is threadedly connected to the first lead screw below, the first lead screw is rotatably connected to the third drive frame, the third drive frame is slidably connected to the buffer plate, the first lead screw is fixedly connected to the output shaft of the seventh motor, and a fourth guide rod is slidably connected to the top of the buffer plate, and the fourth guide rod is fixedly connected to the second fixed cabinet.

[0020] Using the above technical solution, the buffer plate is threadedly connected to the first lead screw at the bottom. The first lead screw is rotatably connected to the third drive frame and driven by the seventh motor. This allows for precise control of the lifting or translation distance of the buffer plate, and the buffer position can be flexibly adjusted according to the height and length of the material, directly supporting the core requirement of "multi-size compatibility" of the equipment. The fourth guide rod, which is slidably connected above the buffer plate, is fixed to the second fixed cabinet. Together with the third drive frame, it restricts the movement direction of the buffer plate, preventing it from shaking when moving, ensuring the stability of the material on the buffer plate, and preventing the material from tipping over.

[0021] As a preferred embodiment of the present invention, a guide groove is provided on the side of the buffer plate, a buffer strip is slidably connected in the guide groove, a limiting pad is fixed below the buffer strip with bolts, and a buffer plate is sandwiched between the limiting pad and the buffer strip;

[0022] Using the above technical solution, the buffer strips are slidably connected in the guide groove on the side of the buffer plate, which can flexibly adjust the spacing of the buffer strips. When conveying narrow materials, the spacing is reduced, and when conveying wide materials, the spacing is increased, directly adapting to the buffering needs of materials of different widths and further enhancing the "multi-size compatibility" capability. The limit pad fixed by bolts below the buffer strips is sandwiched between the buffer plate and the buffer strips, which can firmly lock the buffer strips after adjustment, preventing the buffer strips from shifting during the buffering process and causing material displacement. Moreover, the bolt connection is convenient for disassembly and adjustment, and is suitable for scenarios with high size switching frequency.

[0023] As a preferred technical solution of the present invention, a tenth motor is fixedly connected above the buffer plate, the tenth motor is fixedly connected to the drive roller, the drive roller is configured with a double groove structure on the outside, and a second belt is fitted on one end of the drive roller, and a push roller is fitted on the other end of the second belt. There are six push rollers evenly distributed, and the second belts are staggered on the outside of the push rollers.

[0024] Using the above technical solution, the tenth motor fixed above the buffer plate is fixedly connected to the drive roller. The double-groove structure on the outside of the drive roller can be adapted to two second belts, enhancing the stability of power transmission and avoiding uneven force distribution when using a single belt drive. The six evenly distributed push rollers fitted at the other end of the second belt, together with the staggered second belt, can ensure that the bottom of the material is evenly stressed. Even when conveying long or irregular materials, the conveying can remain stable, without deviation or jamming. The multi-push roller layout can also disperse the material pressure, preventing excessive force at a single point from causing material deformation and protecting the safety of conveying fragile materials.

[0025] As a preferred embodiment of the present invention, a bolted connecting plate is bolted above the buffer strip, a first drive frame is slidably connected to the side of the connecting plate, a fourth lead screw is threadedly connected to the center of the connecting plate, a fifth motor is fixedly connected to the shaft end of the fourth lead screw, the fifth motor is fixedly connected to the first drive frame, a second lead screw is threadedly connected above the first drive frame, the two second lead screws are diagonally distributed, the top of the second lead screw is fixedly connected to the shaft end of the third motor, the third motor is fixedly connected to the cover plate, a first guide rod is fixedly connected to the bottom of the cover plate, the first guide rod is diagonally distributed, the cover plate is fixedly connected to the fourth fixed cabinet, a display screen is fixedly connected to the side of the fourth fixed cabinet, and the fourth fixed cabinet is bolted to the first side plate and the second side plate.

[0026] Using the above technical solution, the connecting plate, bolted above the buffer bar, is slidably connected to the first drive frame on its side. The center of the connecting plate is threadedly connected to the fourth lead screw, which is driven by the fifth motor, enabling precise lateral adjustment of the buffer bar. The first drive frame is threadedly connected to two diagonally distributed second lead screws above it. The tops of the second lead screws are fixed to the shaft end of the third motor, and the diagonally distributed first guide rods fixed at the bottom of the cover plate prevent the first drive frame from tilting, achieving stable longitudinal adjustment of the buffer bar. This ultimately achieves multi-dimensional positioning of the buffer bar, further expanding the equipment's adaptability to materials of different sizes. The cover plate is dustproof and moisture-proof, protecting internal precision components such as the third motor and second lead screws, reducing damage to the core structure from the external environment, and extending the overall lifespan of the equipment. The display screen fixed to the side of the fourth fixed cabinet can display parameters such as buffer position and motor speed in real time, allowing operators to intuitively grasp the equipment's operating status without disassembling for inspection, improving operational convenience and troubleshooting efficiency.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. The eighth motor drives the third lead screw to adjust the position of the first conveyor frame, and the seventh motor drives the first lead screw to adjust the height and horizontal position of the buffer plate. The buffer bars can also slide along the guide groove of the buffer plate to change the spacing. Together with the horizontal and vertical adjustment structures driven by the fifth motor and the third motor respectively, the buffer bars can achieve multi-dimensional positioning. The entire process from conveying to buffering is adapted to materials of different widths, heights and lengths, and accurately achieves the design goal of "compatible with multiple sizes".

[0029] 2. The twelve symmetrical positioning blocks of the support base and the four rectangular positioning holes of the first fixed cabinet ensure precise assembly of components without deviation; the third guide rod and the fourth guide rod respectively limit the movement trajectory of the first conveyor frame and the buffer plate to avoid movement and shaking; the ninth motor, with double reversing wheels and the first belt, transmits power in a balanced manner; the tensioning structure composed of tensioning wheel and counterweight bolts can flexibly adjust the belt tension; the double groove design of the drive roller and the six uniformly pushing rollers ensure that the material is subjected to uniform force, effectively preventing the material from running off course, getting stuck or tipping over;

[0030] 3. The support base and the first fixed cabinet are connected by a positioning block-positioning hole snap-fit ​​connection, which can be disassembled and assembled without complicated tools, making it easy to transport and replace parts; the first side plate, the second side plate, and the three fixed cabinets have the same structure, realizing standardized production, reducing mold investment, and the parts are interchangeable, shortening the maintenance cycle; the display screen on the side of the fourth fixed cabinet displays the operating parameters in real time, so that the equipment status can be grasped without disassembling the machine; the buffer bar is fixed by limit pad bolts, which facilitates quick adjustment of size to adapt to the needs;

[0031] 4. The support base and the straight heat dissipation groove of the third side plate form a linkage heat dissipation to avoid high temperature aging of core components such as motor and lead screw. The cover plate protects the internal precision structure from dust and moisture. The bearing at the connection between the tension shaft and the tension wheel reduces friction loss and significantly extends the overall life of the equipment. The layout of multiple push rollers disperses the material pressure and prevents the material from deforming due to excessive force at a single point. It is suitable for conveying fragile materials and ensures the safety of materials during buffering and conveying. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1-18The technical solution of this invention is as follows: A dual-track buffer machine compatible with multiple sizes; comprising a support base 1, a first fixed cabinet 2, a second fixed cabinet 3, a third fixed cabinet 4, a first side plate 5, a second side plate 6, a cover plate 7, a display screen 8, a heat dissipation trough 9, a fourth fixed cabinet 10, a first blower shroud 11, a second blower shroud 12, a first motor 13, a second motor 14, a third motor 15, a fourth motor 16, a first conveyor frame 17, a buffer plate 18, a second conveyor frame 19, a positioning block 20, a first guide rod 21, a first drive frame 22, a connecting plate 23, a fifth motor 24, and a buffer bar 25. 26.

[0053] A buffer mechanism is provided above the support base 1. The buffer mechanism includes a fourth fixed cabinet 10, a third motor 15, a first guide rod 21, a first drive frame 22, a connecting plate 23, a fifth motor 24, a buffer bar 25, a limiting pad 26, and a second lead screw 49. The first guide rod 21 is located on the side of the fourth fixed cabinet 10. The first drive frame 22 is installed above the first guide rod 21. The second lead screw 49 is installed on the side of the first drive frame 22. The third motor 15 is installed above the second lead screw 49. The connecting plate 23 is installed above the first drive frame 22. The buffer bar 25 and the limiting pad 26 are installed below the connecting plate 23.

[0054] The upper surface of the support base 1 is fixedly connected with twelve symmetrically distributed positioning blocks 20, and the lower surface is provided with a straight heat dissipation groove 9. The left side of the center line is fixedly connected to the second side plate 6, and the right side is fixedly connected to the first side plate 5, and the two have the same structure. The twelve symmetrical positioning blocks 20 can provide precise installation positioning for components such as the upper buffer mechanism and the first fixed cabinet 2, avoid assembly misalignment, and significantly improve the overall assembly stability of the equipment. The straight heat dissipation groove 9 can quickly dissipate the heat inside the base, prevent the hidden circuits and connectors from aging due to high temperature, and extend the service life of the support base 1. The first side plate 5 and the second side plate 6 have the same structure, which can not only achieve standardized production to reduce mold development costs, but also facilitate component interchange during later maintenance and reduce the difficulty of maintenance operations.

[0055] The support base 1 is connected to the first fixed cabinet 2 by engaging with the positioning block 20 and positioning hole 30. The first fixed cabinet 2 is bolted to the side of the third side plate 33, which has the same heat dissipation groove 9. The second fixed cabinet 3 and the third fixed cabinet 4 with the same structure are arranged in sequence on the side. The first fixed cabinet 2 has four rectangular positioning holes 30 at the top and bottom. The engaging design of the positioning block 20 and the positioning hole 30 can complete the assembly and disassembly of the first fixed cabinet 2 and the base without complicated tools, which greatly improves the assembly efficiency and facilitates the disassembly and transportation later. The heat dissipation groove 9 of the third side plate 33 forms a vertical linkage heat dissipation with the base, which enhances the heat dissipation effect of the core components such as the motor and lead screw inside the first fixed cabinet 2 and avoids overheating shutdown. The three fixed cabinets have the same structure, which can realize standardized production to reduce mold investment. The parts are interchangeable, and if a fixed cabinet fails, it can be directly replaced, shortening the maintenance cycle. The four rectangular positioning holes 30 can ensure that the fixed cabinets are accurately aligned vertically and vertically, avoiding tilting and further improving the overall structural stability of the equipment.

[0056] The output shaft of the eighth motor 29, fixed inside the first fixed cabinet 2, is connected to the third lead screw 50. The third lead screw 50 is rotatably connected to the second drive frame 31, and the second drive frame 31 is slidably connected to the first conveyor frame 17. The third guide rod 51 is slidably connected above the first conveyor frame 17. The output shaft of the ninth motor 39, fixed above the first conveyor frame 17, is connected to two symmetrical reversing wheels 37. The outer side of the reversing wheels 37 is fitted with a first belt 38. Below the first belt 38, a tensioning wheel 36 with a tensioning shaft 35 connected to the shaft end is fitted with a bearing. The side of the tensioning shaft 35 is slidably connected to a counterweight bolt 41 connected to the bottom positioning block 20. The second conveyor frame 19, with the same structure, is arranged symmetrically to the first conveyor frame 17. The eighth motor 29 drives the third lead screw 50 to drive the first conveyor frame 19. 7. The linear and precise position adjustment allows for flexible adjustment based on material size, laying the foundation for size compatibility of dual-rail conveying. The third guide rod 51 restricts the sliding trajectory of the first conveyor frame 17 to prevent deviation and ensure smooth conveying. The ninth motor 39, in conjunction with the double reversing wheel 37 and the first belt 38, can balance the power transmission and avoid transmission jamming. The bearings of the tension shaft 35 and tension wheel 36 reduce friction loss. The counterweight bolt 41 and counterweight plate 40 can flexibly adjust the belt tension to adapt to the conveying of materials of different weights. The symmetrical configuration of the dual conveyor frames directly realizes dual-rail conveying, which doubles the efficiency compared to single-rail conveying. It can convey two batches of materials simultaneously and support large-sized materials. The identical structure facilitates production and maintenance. Synchronous adjustment can ensure the consistency of the movement of the two rails and prevent material deviation.

[0057] The buffer plate 18 is threadedly connected to the first lead screw 44 driven by the seventh motor 28 below. The first lead screw 44 is rotatably connected to the third drive frame 45. The fourth guide rod 52 of the second fixed cabinet 3 is slidably connected above the buffer plate 18. A guide groove 47 is opened on the side, and the buffer strip 25 of the buffer plate 18 is slidably connected in the groove and clamped by the lower limit pad 26. The tenth motor 42 fixed above the buffer plate 18 is connected to the double groove drive roller 43. The second belt 48 is fitted on the outside of the drive roller 43. The other end of the second belt 48 is fitted with six evenly distributed push rollers 46. The connecting plate 23 bolted above the buffer strip 25 is slidably connected to the first drive frame 22 on the side. The center line of the connecting plate 23 is connected to the fourth lead screw 53 driven by the fifth motor 24. The first drive frame 22 is connected to the double diagonal second lead screw 49 driven by the third motor 15 above. The bottom of the cover plate 7 is connected to the double diagonal first guide rod 21 and the fourth fixed cabinet 10. The side of the fourth fixed cabinet 10 is connected to the display screen 8 and bolted to the first and second side plates. The seventh motor 28 drives the first lead screw 44 to precisely adjust the lifting and translation distance of the buffer plate 18, adapting to materials of different heights and lengths. The fourth guide rod 52 and the third drive frame 45 limit the movement direction of the buffer plate 18 to prevent shaking and ensure material stability. The buffer strip 25 slides along the guide groove 47 to adjust the spacing, adapting to materials of different widths. The limiting pad 26 can lock the position of the buffer strip 25, and the bolt connection facilitates adjustment, adapting to high-frequency size switching. The tenth motor 42, together with the double groove drive roller 43 and the second belt 48, enhances the stability of power transmission. The six push rollers 46 ensure that the bottom of the material is evenly stressed, preventing deviation and jamming, and dispersing pressure to prevent material deformation. The fifth motor 24 and the third motor 15 drive the buffer strip 25 to adjust laterally and longitudinally, respectively, and together with the first guide rod 21, achieve multi-dimensional positioning, expanding the size adaptation range. The cover plate 7 protects precision components from dust and moisture. The display screen 8 displays operating parameters in real time, improving the convenience of operation and the efficiency of fault diagnosis.

[0058] Working principle: When using a dual-track buffer machine compatible with multiple sizes, before the equipment is started, the support base 1 engages with the positioning holes 30 at the bottom of the first fixed cabinet 2, the second fixed cabinet 3, and the third fixed cabinet 4 through twelve symmetrically distributed positioning blocks 20 on its upper surface, completing the precise assembly of the fixed cabinets; at the same time, the first side plate 5, the second side plate 6, and the third side plate 33 are respectively fixed to the sides of the base and the fixed cabinets, forming an overall frame support for the equipment, ensuring the stability of the position of each component during subsequent operation and preventing displacement;

[0059] According to the size of the material to be processed, the eighth motor 29 in the first fixed cabinet 2 starts, and its output shaft drives the third lead screw 50 to rotate. The third lead screw 50 drives the second drive frame 31 to move in a linear direction, which in turn drives the first conveyor frame 17 to slide along the third guide rod 51, adjusting the lateral position of the first conveyor frame 17. Similarly, the symmetrically configured second conveyor frame 19 is adjusted synchronously so that the distance between the two conveyor frames is adapted to the width of the material. After the adjustment is completed, the ninth motor 39 above the first conveyor frame 17 starts, driving the two symmetrical reversing wheels 37 to rotate. The reversing wheels 37 transmit power through the first belt 38. At the same time, the tensioning wheel 36 on the tensioning shaft 35 maintains the tension of the first belt 38 under the action of the counterweight bolt 41 and the positioning block 20, avoiding transmission slippage and providing stable power for the dual-rail conveyor.

[0060] When materials are conveyed to the buffer area via the double conveyor frame, the seventh motor 28 associated with the second fixed cabinet 3 starts, and its output shaft drives the first lead screw 44 to rotate. The first lead screw 44 drives the third drive frame 45 to move, thereby driving the buffer plate 18 to rise or fall or move horizontally along the fourth guide rod 52, adjusting the height and horizontal position of the buffer plate 18 to match the height and length of the materials. At the same time, according to the width of the materials, the fifth motor 24 starts, driving the fourth lead screw 53 to rotate, driving the connecting plate 23 to slide along the first drive frame 22, thereby driving the buffer strips 25 to adjust the spacing along the guide groove 47 of the buffer plate 18. After the adjustment is completed, the limiting pads 26 under the buffer strips 25 are locked in position by bolts to prevent the buffer strips 25 from shifting during the buffering process. If further fine-tuning of the longitudinal position of the buffer strips 25 is required, the third motor 15 starts, driving the second lead screws 49 distributed diagonally to rotate, driving the first drive frame 22 to move smoothly along the first guide rod 21, realizing multi-dimensional positioning of the buffer strips 25, and ensuring that the materials fall accurately into the buffer area.

[0061] When the buffered material needs to be output, the tenth motor 42 above the buffer plate 18 starts, driving the double-groove drive roller 43 to rotate. The drive roller 43 drives six evenly distributed push rollers 46 to rotate through the second belt 48. The staggered distribution of the second belt 48 ensures that the bottom of the material is evenly stressed, so that the material is smoothly conveyed out of the buffer area. Throughout the process, the display screen 8 on the side of the fourth fixed cabinet 10 displays the operating parameters such as the speed of each motor and the buffer position in real time. The operator can intuitively grasp the status of the equipment through the display screen 8 and make timely adjustments if any abnormality occurs. At the same time, the straight heat dissipation groove 9 of the support base 1 and the third side plate 33 continuously dissipates the heat inside the equipment, and the cover plate 7 is dustproof and moistureproof, ensuring the stable operation of the core components and ensuring the continuous and efficient operation of the entire process.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
