Description

Technical Field

[0001] This utility model relates to the technical field of flexible decorative material processing equipment, and more specifically, to an automatic punching and feeding mechanism for flexible decorative materials. Background Technology

[0002] The flexible plastic substrate used for artificial flower petals is widely used in home decoration, wedding floral arrangements, and handicrafts due to its high flexibility and realistic shaping effect. During petal processing, the flexible plastic substrate needs to be batch-cut into shape. The stability of the feeding and the accuracy of the positioning directly determine the cutting quality and production efficiency of the petals, making it a core processing step.

[0003] Currently, the industry mostly uses manual feeding or simple conveyor belt feeding for punching and feeding this type of flexible plastic sheet, combined with fixed stop blocks for limiting.

[0004] However, the existing technologies have certain problems in practical applications: on the one hand, the flexible plastic substrate is soft and easily deformed, and the existing feeding mechanism does not have an adjustable pressure roller structure to match the thickness. The substrate is prone to wrinkling and poor adhesion. Moreover, the width of the limiting component is fixed, which cannot adapt to whole-plate substrates of different widths. The feeding process is prone to lateral deviation. On the other hand, the mechanism does not have an automatic pulling and traction structure. The flexible substrate is prone to slipping and the feeding is discontinuous. There is no continuous guidance when conveying to the punching area. The substrate is prone to displacement during punching, resulting in petal size deviation and poor forming. At the same time, the degree of automation is low, which makes it difficult to meet the needs of large-scale and efficient production. Therefore, there is an urgent need for an automatic punching and feeding mechanism for plastic simulated flower substrates to solve the above problems. Utility Model Content

Through the coordinated structure of hydraulic cylinder lifting, bidirectional screw guidance and gripper traction, and gear rack punching, it achieves multi-specification material adaptation, precise and automated feeding and punching, reduces scrap rate, and improves production efficiency and batch processing yield.

[0006] According to a first aspect of the present invention, an automatic punching and feeding mechanism for flexible decorative materials is provided, comprising a first frame and a conveyor belt mounted on the first frame for conveying materials, and further comprising: a mounting frame symmetrically and liftably mounted on the first frame, wherein rollers for auxiliary conveying are rotatably mounted on the mounting frame, and a guide for positioning materials is mounted on the mounting frame; a second frame, disposed at the discharge end of the first frame, wherein a punching assembly for punching materials is connected to the second frame via a driving component, and a pulling component for pulling materials is mounted on the second frame.

[0007] Optionally, the first frame is connected to the mounting bracket on the corresponding side via a hydraulic cylinder for adjusting the position of the roller. The guide includes guide frames symmetrically mounted on the mounting bracket. One set of the guide frames is rotatably connected to a bidirectional screw, and the other set of the guide frames is symmetrically provided with rails. Both sets of threaded sections of the bidirectional screw are threaded with a lever, and the other end of the lever is slidably connected to the corresponding rail.

[0008] Optionally, a first drive motor is fixedly mounted on the mounting bracket. The output end of the first drive motor is connected to the end of the bidirectional screw. When the first drive motor is working, the two sets of actuating rods on the bidirectional screw move closer to or further away from each other.

[0009] Optionally, the number of rollers is at least six, and the rollers are arranged linearly and equidistantly along the length of the mounting frame. A limiting plate adapted to the rollers is fixedly installed on the actuating rod, and the rollers are rotatably connected in the rotating holes opened in the limiting plate for assisting material feeding. When the two sets of actuating rods are positioned, the two sets of limiting plates contact the corresponding side of the material and form a guide area.

[0010] Optionally, the second frame is provided with symmetrical rectangular slots for guidance, and each rectangular slot is slidably connected with a guide plate for auxiliary guidance. The guide plate is connected to a limiting plate. When the lever moves the limiting plate, the limiting plate moves the guide plate along the path of the rectangular slot and forms an auxiliary guidance area.

[0011] Optionally, the driving component includes cylinders symmetrically and fixedly mounted on the second frame. The output end of the cylinder is fixedly connected to a crossbeam. The blanking assembly is slidably connected to the guide rail of the crossbeam. A second drive motor is fixedly mounted on the frame of the blanking assembly. The output end of the second drive motor is fixedly connected to a gear, and the gear meshes with a rack on the crossbeam.

[0014] 1. According to one embodiment of this disclosure, the automatic punching and feeding mechanism for flexible decorative materials, through the lifting and adjusting structure of the hydraulic cylinder and mounting frame on the first frame, the symmetrical transmission structure of the bidirectional screw and two sets of actuating rods in the guide member, and the linkage guiding structure of the limiting plate and the guide plate on the second frame, can not only quickly adapt to flexible decorative materials of different thicknesses and widths, but also complete the processing and transformation without disassembling the equipment, greatly improving the adaptability and ease of use of the equipment; it can also suppress lateral deviation and connection jamming during the material conveying process through the limiting of the actuating rod by the track and the guiding effect of the rectangular groove on the guide plate, ensuring the straightness consistency of the feeding path and effectively reducing the punching scrap rate caused by guiding deviation.

[0015] 2. According to one embodiment of this disclosure, the automatic punching and feeding mechanism for flexible decorative materials achieves integrated automatic linkage from feeding to punching through the traction and tensioning structure of the electric guide rail, sliding plate and electric gripper on the second frame, the smooth lifting structure of the cylinder and crossbeam in the drive component, and the meshing transmission structure of the second drive motor, gear and rack on the punching assembly. It eliminates the need for manual traction and positioning, reducing labor intensity and improving operational safety and production efficiency. At the same time, through the rolling auxiliary transmission of rollers, the anti-slip clamping effect of shims, and the precise sliding positioning of the punching assembly along the crossbeam guide rail, it effectively suppresses material displacement and component running deviation during punching, ensuring the dimensional accuracy and cross-sectional flatness of punching, and keeping the yield rate of batch production at a high level to meet the needs of large-scale processing.

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0029] like Figure 1-6 As shown, an automatic punching and feeding mechanism for flexible decorative materials includes a first frame 1 and a conveyor belt 2 installed on the first frame 1 for conveying materials.

[0030] It also includes a mounting frame 3 that is symmetrically and liftably mounted on the first frame 1. The mounting frame 3 is rotatably mounted with rollers 4 for auxiliary conveying. The first frame 1 is connected to the mounting frame 3 on the corresponding side via a hydraulic cylinder for adjusting the position of the rollers 4.

[0031] Here, the hydraulic cylinder is rigidly connected to the first frame 1 and the mounting frame 3, which can precisely control the lifting stroke of the mounting frame 3, avoid the mounting frame 3 from shaking or shifting during the lifting process, and ensure the accuracy of the roller 4 position adjustment.

[0032] Furthermore, the hydraulic cylinder can steplessly adjust the height of the mounting frame 3 according to the actual thickness of the flexible decorative material, so that the roller 4 always keeps in contact with the material surface, adapting to the feeding operation of flexible decorative materials of different thicknesses.

[0033] Furthermore, the hydraulic cylinder-driven lifting mechanism of the mounting bracket 3 has a fast response speed, which can quickly complete the height positioning of the roller 4 during the equipment start-up and shutdown phases, avoiding the material being squeezed and deformed due to excessive pressure on the roller 4, or failing to play an auxiliary transmission role due to insufficient pressure.

[0034] The mounting frame 3 is equipped with guides for positioning materials. The guides include guide frames 7 symmetrically mounted on the mounting frame 3. One set of guide frames 7 is rotatably connected to a bidirectional screw 8, and the other set of guide frames 7 is symmetrically provided with rails 9. Both sets of threaded sections of the bidirectional screw 8 are threadedly connected to a lever 10, and the other end of the lever 10 is slidably connected to the corresponding rail 9. A first drive motor 11 is fixedly mounted on the mounting frame 3. The output end of the first drive motor 11 is connected to the end of the bidirectional screw 8. When the first drive motor 11 is working, the two sets of levers 10 on the bidirectional screw 8 move closer to or further away from each other.

[0035] Here, the bidirectional screw 8 and the two sets of actuating rods 10 adopt a symmetrical threaded connection structure, which can ensure that the two sets of actuating rods 10 move synchronously and keep the moving distance consistent, so that the material is always in the center position of the conveying mechanism and improves the feeding centering accuracy.

[0036] Furthermore, the track 9 limits the movement path of the lever 10 to prevent the lever 10 from deflecting as the bidirectional screw 8 rotates, thus ensuring the straightness of the lever 10's translation.

[0037] Furthermore, the first drive motor 11 adopts a forward and reverse drive mode, which can flexibly control the opening and closing range of the two sets of levers 10 without manual adjustment, reducing manual operation costs and improving the automation level of guide structure adjustment.

[0038] There are at least six rollers 4, and multiple rollers 4 are arranged linearly and equidistantly along the length of the mounting frame 3. A limiting plate 12 adapted to the rollers 4 is fixedly installed on the actuating rod 10, and the rollers 4 are rotatably connected in the rotating hole 13 opened on the limiting plate 12 for assisting material feeding. When the two sets of actuating rods 10 are positioned, the two sets of limiting plates 12 contact the corresponding side of the material and form a guide area.

[0039] Here, multiple sets of rollers 4 are linearly and equidistantly arranged on the mounting frame 3, which can increase the contact area with the flexible decorative material, disperse the force during material transmission, and avoid the problem of wrinkles, tearing and damage to the material due to excessive local force.

[0040] Furthermore, the roller 4 is rotatably connected to the limiting plate 12 through the rotating hole 13. When the material is conveyed, the roller 4 rotates synchronously with the material, changing the sliding friction to rolling friction, reducing the friction between the material and the limiting plate 12, and protecting the material surface from being scratched.

[0041] Furthermore, the guide area formed by the two sets of limiting plates 12 can limit the sides of the material in all directions, preventing the material from shifting laterally during long-distance transportation, ensuring the straightness of the material transportation path, and providing dimensional assurance for subsequent punching processing.

[0042] The second frame 5 is located at the discharge end of the first frame 1. The second frame 5 is symmetrically provided with rectangular grooves 14 for guiding. Each rectangular groove 14 is slidably connected with a guide plate 15 for auxiliary guiding. The guide plate 15 is connected to the limiting plate 12. When the lever 10 drives the limiting plate 12 to move, the limiting plate 12 drives the guide plate 15 to move along the path of the rectangular groove 14 and form an auxiliary guiding area.

[0043] Here, the guide plate 15 is fixedly connected to the limiting plate 12 and can be adjusted synchronously with the limiting plate 12 to realize the integrated adjustment of the feeding guide structure throughout the process. There is no need to adjust the guide components of the punching area separately, which simplifies the operation process.

[0044] Furthermore, the rectangular groove 14 guides and limits the movement of the guide plate 15, ensuring that the movement trajectory of the guide plate 15 is consistent with that of the limiting plate 12, so that the guide areas of the conveying section and the punching section remain connected, and preventing the material from getting stuck or shifting at the connection position.

[0045] Furthermore, the auxiliary guide area formed by the guide plate 15 can continue to limit the material, allowing the material to enter the punching area smoothly, solving the problem of material deviation when transitioning from the conveying mechanism to the punching mechanism, and improving the smoothness of process connection.

[0046] The second frame 5 is connected to a blanking assembly 6 for blanking materials via a drive component. The drive component includes cylinders 16 symmetrically and fixedly mounted on the second frame 5. A crossbeam 17 is fixedly connected to the output end of the cylinders 16. The blanking assembly 6 is slidably connected to the guide rail of the crossbeam 17. A second drive motor 18 is fixedly mounted on the frame of the blanking assembly 6. A gear 19 is fixedly connected to the output end of the second drive motor 18, and the gear 19 meshes with a rack on the crossbeam 17. When the second drive motor 18 drives the gear 19 to move along the rack path, the blanking assembly 6 moves along the guide rail.

[0047] Here, the symmetrically arranged cylinders 16 synchronously drive the crossbeam 17 to rise and fall, which can ensure that the crossbeam 17 is subjected to uniform force, avoid the crossbeam 17 tilting and causing uneven punching pressure of the punching assembly 6, and improve the flatness of the punching section.

[0048] Furthermore, the meshing transmission method of gear 19 and rack provides high transmission accuracy and smooth operation, and can precisely control the movement position of the punching component 6 on the crossbeam 17, realizing precise punching of flexible decorative materials at different points and expanding the processing range.

[0049] Furthermore, the structure of the blanking assembly 6 sliding along the guide rail of the crossbeam 17 can reduce frictional loss when the blanking assembly 6 moves, extend the service life of the component, and at the same time ensure that the blanking assembly 6 does not shake during the movement, thus ensuring the accuracy of the blanking dimensions.

[0050] The second frame 5 is equipped with a pulling component for pulling materials. The pulling component includes electric guide rails 20 symmetrically installed on the second frame 5. The second frame 5 is equipped with a sliding plate 21, and the sliding plate 21 is connected to the output end of the corresponding electric guide rail 20. An electric gripper 22 for clamping materials is fixedly installed at the bottom of the sliding plate 21, and a pad 23 for anti-slip is fixedly installed on the electric gripper 22.

[0051] Here, the electric guide rail 20 drives the sliding plate 21 to move, which can realize the automatic pulling and feeding of materials, replace manual material pulling, reduce manual intervention, and improve the automation level of the equipment.

[0052] Furthermore, the electric gripper 22 can firmly clamp the end of the material, and with the traction of the electric guide rail 20, it keeps the material in a tense state during the punching process, avoiding material slack that could lead to distortion of the punched shape and dimensional deviation.

[0053] Furthermore, the pad 23 can increase the friction between the electric gripper 22 and the material, preventing the material from slipping and falling off during the clamping process. At the same time, the pad 23 is soft and will not leave clamping marks on the material surface, ensuring the appearance integrity of the flexible decorative material.

[0054] In this invention, flexible decorative material is conveyed via the conveyor belt 2 of the first frame 1. The lifting and lowering of the mounting frame 3 can be controlled by adjusting the hydraulic cylinder on the first frame 1, so that the roller 4 can be adapted to the material thickness to ensure conveying stability. The first drive motor 11 drives the bidirectional screw 8 to rotate, causing the two sets of actuating rods 10 to move closer or further away from each other along the track 9. This forms a guide area that matches the width of the material through the limiting plate 12. At the same time, the limiting plate 12 drives the guide plate 15 on the second frame 5 to move synchronously along the rectangular groove 14, achieving precise guidance throughout the material conveying to the punching area and avoiding deviation or wrinkles.

[0055] After the material is conveyed to the second frame 5, the electric gripper 22 clamps the end of the material. The electric guide rail 20 drives the sliding plate 21 to smoothly pull the material to the punching station and keep it in a tensioned state to prevent slippage or discontinuous feeding. Then, the cylinder 16 pushes the crossbeam 17 down, so that the punching component 6 is close to the material. The second drive motor 18 meshes with the rack on the crossbeam 17 through the gear 19 to drive the punching component 6 to move along the guide rail of the crossbeam 17 to achieve precise punching at different positions. Throughout the process, the roller 4 assists in the smooth transmission of the material through the rotation hole 13 on the limiting plate 12. The limiting plate 12 and the guide plate 15 continuously ensure the straight-line transmission of the material. The pad 23 on the electric gripper 22 enhances the clamping stability. Through the coordinated cooperation of various components, the feeding and punching processes are connected and the accuracy is controllable, further improving the production and processing efficiency.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
