Description

Technical Field

[0001] This utility model relates to the field of decorative fabric processing technology, and more specifically, to a hot-pressing composite mechanism for decorative fabric ribs. Background Technology

[0002] In the field of flexible plastic artificial flower processing technology, in order to improve the structural rigidity, shape stability and durability of artificial flower stems, petals and other parts, it is necessary to use hot pressing process to fix the ribs to the flexible plastic flower body. This process needs to be adapted to the thermoplastic bonding characteristics of flexible plastic and has high requirements for the alignment accuracy and ease of disassembly and assembly of hot pressing molds.

[0003] Existing hot-pressing lamination equipment for decorative fabric ribs has several problems: First, most equipment uses a single-feeding hot-pressing operation mode, lacking independent loading / unloading and hot-pressing stations. Operators must reach into the high-temperature hot-pressing area to load and unload materials, which not only poses a risk of burns but also risks touching the unshaped, flexible plastic flower body, causing deformation and affecting the product molding effect. Second, simulated flowers come in various styles and specifications, requiring frequent changes of suitable hot-pressing molds. However, existing molds are mostly fixed with fasteners, requiring tools for disassembly and assembly, making the operation cumbersome and inefficient, and unable to achieve rapid switching between multiple specifications. Third, some multi-station equipment lacks a synchronous adjustment structure for mold positions, requiring manual adjustment of each station's mold individually. This operation is time-consuming, and the alignment accuracy of each station is inconsistent, resulting in inconsistent product quality in batch processing. Therefore, we urgently need a hot-pressing lamination mechanism for decorative fabric ribs to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a hot-pressing composite mechanism for decorative fabric ribs. By setting up a multi-station rotary structure with a stepped magnetic positioning component, it enables quick mold disassembly and replacement and safe operation in different zones. With the help of synchronous adjustment and elastic limiting structure, it ensures mold alignment accuracy and improves processing efficiency and batch product forming quality.

[0005] According to a first aspect of the present invention, a hot-pressing composite mechanism for decorative fabric ribs is provided, comprising a machine base for processing and an upper mold for hot pressing that is lifted and mounted on a machine base support by a cylinder, and further comprising: a worktable rotatably connected to the machine base, wherein a mounting bracket is slidably connected to the worktable via an adjusting member, and a lower mold adapted to the upper mold is detachably mounted on the mounting bracket for placing decorative fabric, and a limiting member for pressing against the adjusting member is also provided on the worktable.

[0006] Optionally, the number of lower molds is at least four sets, and the four sets of lower molds are arranged in a ring at equal intervals on the worktable. A drive motor for rotating the worktable is fixedly installed inside the machine. The output end of the drive motor is connected to the worktable. When the drive motor is working, the lower molds are coaxial with the upper molds in sequence and form a hot pressing zone.

[0007] Optionally, the adjusting component includes a rectangular notch on the worktable, the rectangular notch being opened corresponding to the lower mold position, and guide rails symmetrically installed on the inner wall of the rectangular notch. A lead screw is rotatably connected to one set of the guide rails, and the other end of the lead screw passes through the guide rail and is fixedly installed with a bevel gear. A guide rod is fixedly installed in the other set of the guide rails. The mounting bracket is set in the rectangular notch, and one side of the mounting bracket is threadedly connected to the lead screw, and the other side is slidably connected to the guide rod.

[0008] Optionally, a ring track is fixedly installed on the lower part of the workbench, and a ring plate is slidably connected inside the ring track. A gear ring adapted to the bevel gear is fixedly installed on the ring plate, and the bevel gear meshes with the gear ring. When the ring plate drives the gear ring to rotate, the bevel gear rotates accordingly and drives the lead screw to rotate, so as to adjust the position of the mounting bracket.

[0009] Optionally, the mounting bracket is integrally formed with a magnetic base for placing the lower mold, and a magnetic block adapted to the magnetic base is fixedly installed on the lower part of the lower mold. When the magnetic block is magnetically attracted to the magnetic base, the lower mold and the magnetic base abut against each other to form an installation area.

[0010] Optionally, the axial cross-section of the magnetic base is a stepped structure, with each step arranged sequentially from top to bottom along its own central axis, and the radial dimension of each step decreasing downwards along the central axis.

[0011] Optionally, a damping pad for anti-slip is fixedly installed on the annular plate.

[0012] Optionally, the limiting member includes a connecting rod fixedly installed on the workbench, and the end of the connecting rod is hinged to a lever for limiting the rotation of the annular plate. When the lever abuts against the connecting rod, a limiting zone is formed.

[0013] 1. According to one embodiment of this disclosure, the decorative fabric rib hot pressing composite mechanism uses a multi-station structure arranged in a ring, combined with a magnetic base and magnetic blocks with a stepped positioning structure to quickly align and replace molds of different specifications without the need for auxiliary fasteners. At the same time, the material loading and unloading operation and the high-temperature hot pressing operation can be carried out in separate areas, and each process can be carried out synchronously. This not only improves the on-site operating conditions and reduces the operation risk, but also effectively improves the overall processing adaptability and continuous production efficiency of the equipment.

[0014] 2. According to one embodiment of this disclosure, the decorative fabric reinforcement hot pressing composite mechanism achieves synchronous position fine adjustment of the lower molds at all workstations by using a gear ring to link bevel gears and lead screws. At the same time, it relies on connecting rods, levers, and clamping springs to form an elastic pressing and limiting structure, which effectively limits the offset rotation of the annular plate during the operation of the worktable, stably maintains the coaxial fit accuracy of the upper mold and each group of lower molds, reduces processing errors, ensures the molding consistency of mass-produced products, and optimizes the long-term operational stability of the equipment.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] like Figure 1-5 As shown, a decorative fabric reinforcement hot pressing composite mechanism includes a machine base 1 for processing and an upper mold 2 that is lifted and mounted on the support of the machine base 1 by a cylinder for hot pressing.

[0028] It also includes a worktable 3 rotatably connected to the machine base 1. A mounting bracket 4 is slidably connected to the worktable 3 via an adjusting component. A lower mold 5 adapted to the upper mold 2 is detachably mounted on the mounting bracket 4 for placing decorative fabric. A magnetic base 15 for placing the lower mold 5 is integrally formed on the mounting bracket 4. A magnetic block 16 adapted to the magnetic base 15 is fixedly mounted on the lower part of the lower mold 5. When the magnetic block 16 and the magnetic base 15 are magnetically attracted, the lower mold 5 and the magnetic base 15 abut against each other to form an installation area. The axial section of the magnetic base 15 is a stepped structure. Each step is arranged sequentially from top to bottom along its own central axis, and the radial dimension of each step decreases step by step downwards along the central axis.

[0029] Here, the magnetic base 15 of the mounting bracket 4, which is integrally formed, forms a magnetic attraction with the magnetic block 16 at the bottom of the lower mold 5. The magnetic attraction force enables the lower mold 5 to be quickly positioned and installed without the need for additional fasteners such as bolts and nuts. The disassembly and assembly process can be completed simply by magnetic attraction and separation, which effectively solves the problem of traditional molds relying on tools for disassembly and assembly and the cumbersome operation. At the same time, the magnetic connection method will not cause structural damage to the lower mold 5 or the mounting bracket 4, and extends the service life of the components.

[0030] Furthermore, the stepped axial cross-sectional structure of the magnetic base 15 can form an axial limit with the magnetic block 16 through the end faces of each step when the magnetic block 16 is attached to the magnetic base 15. At the same time, the radial dimension difference of the steps forms a radial guide, so that the lower mold 5 is automatically aligned with the central axis during installation, ensuring that the alignment reference of the lower mold 5 and the upper mold 2 is consistent, and avoiding misalignment of the ribs and decorative fabric during hot pressing due to installation offset.

[0031] Furthermore, the one-piece magnetic base 15 not only ensures the structural integrity with the mounting bracket 4 and improves load-bearing stability, but also combines positioning and fixing functions through a stepped magnetic design. This breaks through the limitation of traditional magnetic installation, which can only achieve fixing but cannot guarantee precise positioning. It simultaneously improves the disassembly and assembly efficiency and installation accuracy of the lower mold 5, and adapts to the need for rapid switching of multiple mold specifications.

[0032] The number of lower molds 5 is at least four sets. The four sets of lower molds 5 are arranged in a ring at equal intervals on the worktable 3. A drive motor 6 for rotating the worktable 3 is fixedly installed inside the machine base 1. The output end of the drive motor 6 is connected to the worktable 3. When the drive motor 6 is working, the lower molds 5 are coaxial with the upper molds 2 in sequence and form a hot pressing zone.

[0033] Here, multiple sets of lower molds 5 arranged in a ring at equal intervals on the workbench 3, together with the drive motor 6 inside the machine base 1, form a multi-station rotating structure. During operation, the drive motor 6 drives the workbench 3 to rotate at a uniform speed, so that each set of lower molds 5 enters the hot pressing zone in sequence to cooperate with the upper mold 2. Operators can load and unload decorative fabrics at workstations outside the hot pressing zone, effectively avoiding the safety risk of hands reaching into the hot pressing zone and improving the problem of insufficient safety in traditional single-stage hot pressing equipment.

[0034] Furthermore, the drive motor 6 directly drives the worktable 3 to rotate, realizing the automatic coaxial alignment of the lower mold 5 and the upper mold 2, replacing the manual adjustment of the position of the worktable 3, reducing human error. At the same time, the rotation speed of the worktable 3 can be linked with the hot pressing cycle of the upper mold 2 to ensure continuous hot pressing operation and avoid process interruption.

[0035] Furthermore, the multi-station circular layout design breaks through the structural limitations of traditional single-station or double-station designs. Through the cyclical operation of at least four sets of lower molds 5, the loading and unloading processes and hot pressing processes can be carried out in parallel, significantly increasing the processing volume per unit time. At the same time, the number of lower molds 5 can be flexibly increased or decreased according to production needs, taking into account both mass production and small-batch customized processing, and adapting to different production scenarios.

[0036] The adjusting component includes a rectangular notch 7 opened on the workbench 3, which is opened at the position of the lower mold 5. The inner wall of the rectangular notch 7 is symmetrically equipped with guide rails 8. One set of guide rails 8 is rotatably connected to a lead screw 9, and the other end of the lead screw 9 passes through the guide rail 8 and is fixedly installed with a bevel gear 10. The other set of guide rails 8 is fixedly installed with a guide rod 11. The mounting bracket 4 is set in the rectangular notch 7, and one side of the mounting bracket 4 is threadedly connected to the lead screw 9, and the other side is slidably connected to the guide rod 11.

[0037] Here, the rectangular notch 7 on the worktable 3 corresponding to the position of the lower mold 5 provides an independent sliding adjustment space for the mounting bracket 4. The guide rails 8 symmetrically installed on the inner wall of the rectangular notch 7 constrain the movement trajectory of the mounting bracket 4. Together with the lead screw 9 on one side and the guide rod 11 on the other side, the mounting bracket 4 can slide smoothly along the direction of the guide rail 8, reducing the occurrence of jamming or deviation during the adjustment process.

[0038] Furthermore, the threaded connection between the lead screw 9 and the mounting bracket 4 converts the rotational motion of the lead screw 9 into the linear motion of the mounting bracket 4, making the adjustment process precise and controllable. Simultaneously, the sliding fit between the guide rod 11 and the mounting bracket 4 counteracts the lateral force generated by the threaded transmission of the lead screw 9, ensuring that the mounting bracket 4 drives the lower mold 5 to perform purely linear motion, thus improving the alignment accuracy between the lower mold 5 and the upper mold 2.

[0039] A ring track 12 is fixedly installed on the lower part of the workbench 3, and a ring plate 13 is slidably connected inside the ring track 12. A gear ring 14 adapted to the bevel gear 10 is fixedly installed on the ring plate 13, and the bevel gear 10 meshes with the gear ring 14. When the ring plate 13 drives the gear ring 14 to rotate, the bevel gear 10 rotates and drives the lead screw 9 to rotate, which is used to adjust the position of the mounting bracket 4. A damping pad 17 for anti-slip is fixedly installed on the ring plate 13.

[0040] Here, the annular track 12 at the bottom of the workbench 3 provides stable rotational support for the annular plate 13. The gear ring 14 on the annular plate 13 meshes with the bevel gears 10 of each adjusting component. Rotating the annular plate 13 can drive all the bevel gears 10 to rotate synchronously, and then drive all the mounting brackets 4 to adjust synchronously through the lead screw 9. There is no need to adjust the lower mold 5 of each station individually, which simplifies the operation process.

[0041] Furthermore, the annular structure of the annular track 12 is adapted to the rotation trajectory of the worktable 3, ensuring that the gear ring 14 and each bevel gear 10 always maintain stable meshing when the annular plate 13 rotates, resulting in high transmission efficiency and less risk of tooth dislodgement. At the same time, the damping pad 17 on the annular plate 13 can increase the friction between the annular plate 13 and the contact surface, preventing the annular plate 13 from rotating erroneously due to vibration during equipment operation, and ensuring the initial fixation of the adjustment position.

[0042] The workbench 3 is also provided with a limiting member for pressing the adjusting member. The limiting member includes a connecting rod 18 fixedly installed on the workbench 3. The end of the connecting rod 18 is hinged to a lever 19 for limiting the rotation of the annular plate 13. When the lever 19 abuts against the connecting rod 18, a limiting area is formed.

[0043] Here, the connecting rod 18, which is fixedly installed on the workbench 3, cooperates with the hinged lever 19. A special clamping spring is set between the two. Relying on the elastic force of the clamping spring, the lever 19 is driven to keep in a state of pressing against the annular plate 13. The rotational freedom of the annular plate 13 is constrained by physical pressure. The overall structure is compact and simple, and the manual operation is convenient.

[0044] Furthermore, during the operation of the equipment, the workbench 3 continuously rotates, and the vibration and rotational inertia generated by the operation can easily cause the annular plate 13 to deflect. The clamping spring can continuously provide a constant clamping force to the lever 19, ensuring that the lever 19 always fits against the limiting working surface, avoiding the lever 19 from loosening and reliably limiting the autonomous rotation of the annular plate 13.

[0045] In this invention, firstly, each set of lower molds 5 with magnetic blocks 16 is placed above the magnetic base 15 of the mounting bracket 4. The lower molds 5 are quickly aligned and pre-installed using magnetic adsorption and the stepped structure of the magnetic base 15, adapting to the composite processing requirements of decorative fabric ribs of different specifications. Then, the operator can rotate the annular plate 13, which synchronously drives each set of bevel gears 10 and lead screws 9 to rotate via the gear ring 14. The lead screw 9 and guide rod 11 work together to drive multiple mounting brackets 4 to move synchronously, uniformly calibrating the relative positions of the lower molds 5 and upper molds 2 at each workstation. After position adjustment, the lever 19 is activated, using the connecting rod 18 and lever 19... The springs between the 9 provide continuous elastic clamping force, ensuring that the lever 19 firmly abuts against the limiting ring plate 13, preventing the ring plate 13 from rotating and shifting due to vibration and inertia during the rotation of the worktable 3. After the equipment is started, the drive motor 6 inside the machine table 1 drives the worktable 3 to rotate at a uniform speed, causing multiple sets of lower molds 5 to rotate sequentially to the hot pressing area and cooperate with the upper mold 2 on the same axis. The cylinder drives the upper mold 2 to move downward to complete the hot pressing composite operation of the decorative fabric and the rib. The operator can simultaneously perform material loading and unloading operations at an idle workstation away from the high-temperature hot pressing area, ensuring operational safety while realizing multi-station cyclic continuous processing, effectively improving overall processing efficiency and product forming accuracy.
