Description

Technical Field

[0001] This utility model relates to the field of composite press technology, and more specifically, to a pressure distribution uniformity and buffering structure for a composite press. Background Technology

[0002] A laminating machine is used to bond two or more layers of materials together with adhesives, giving the original materials new functions. Examples include laminating films with aluminum foil, films with paper, and non-woven fabrics. It can also be used to laminate films, sponges, and fabrics. Most common flexible packaging materials are laminated products, widely used in the production of automotive soft-touch interiors.

[0003] Among them, the patent with announcement number CN217435236U discloses a hot press laminating machine, including a hot press laminating machine body, a lower mold and an upper mold. A box is fixedly connected to the rear side of the hot press laminating machine body. A storage cavity is opened in the box. A first opening and a second opening are opened on the box and on both sides of the storage cavity. A height adjustment mechanism is installed on the side of the box near the second opening. A multi-stage electric telescopic rod is fixedly connected to the lifting end of the height adjustment mechanism. The telescopic end of the multi-stage electric telescopic rod is placed in the storage cavity through the second opening. A mounting plate is fixedly connected to the telescopic end of the multi-stage electric telescopic rod. A first mounting groove and a second mounting groove are opened on the upper and lower walls of the mounting plate, respectively. A plurality of first infrared lamps are fixedly connected in the first mounting groove.

[0004] When in use, the structure uses a motor to drive the threaded cylinder to rotate, which allows the multi-stage electric telescopic rod to move up and down, making it easy to adjust the distance between the second infrared lamp and the lower mold. The multi-stage electric telescopic rod can also retract the mounting plate into the storage cavity. However, this structure is difficult to ensure uniform pressure distribution during pressurization and is not easy to provide buffering for the workpiece when it is under stress, resulting in poor pressurization effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pressure distribution uniformity and buffering structure for a composite machine, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a pressure distribution uniformity and buffering structure for a composite machine, comprising a press body, wherein a pressurizing component and a buffering component are provided on the press body;

[0007] The pressurizing assembly includes an eccentric shaft disposed on the top of the press body, the eccentric shaft being rotatably connected to the press body, a reinforcing pressure rod being sleeved on the outer side of the eccentric shaft, and a guide slide frame being disposed at the bottom of the reinforcing pressure rod;

[0008] The pressurizing assembly also includes a fine-tuning arc groove at the bottom of the guide slide frame, in which a force-dispersing block is inserted. A connecting rod is threaded to the bottom of the reinforcing rod, and a hinge seat is hinged to the outside of the connecting rod. The hinge seat extends to the guide slide frame and is detachably connected to the guide slide frame. The guide slide frame is slidably connected to the press body. A drive motor is bolted to one side of the top of the press body. A first pulley is provided at the output end of the drive motor, and a second pulley is fixedly provided at one end of the eccentric shaft. The first pulley and the second pulley are connected by belt drive.

[0009] As can be seen, in the above technical solution, when the reinforcing rod moves up and down, it drives the connecting rod to move, which in turn enables the hinge seat to drive the guide slide frame to move up and down, which in turn causes the force-dispersing block to move and pressurize the material. Furthermore, the guide slide frame is slidably connected to the press body, which can guide and limit the movement of the guide slide frame to ensure the stability of the guide slide frame during movement. At the same time, the force-dispersing block can also be finely adjusted in the fine-tuning arc groove, which makes it easy to distribute the pressure evenly on the workpiece and ensure the stability of the workpiece during pressurization.

[0010] Optionally, in one possible implementation, the buffer assembly includes a pad plate disposed at the bottom of the guide slide frame, a first reinforcing plate disposed at the bottom of the pad plate, the first reinforcing plate being bolted to the press body, a second reinforcing plate disposed at the top of the first reinforcing plate, a folding rod disposed between the second reinforcing plate and the first reinforcing plate, a spring rod being connected to one side of the bottom of the folding rod, one side of the folding rod being located on the second reinforcing plate and the first reinforcing plate and being rotatably connected to the second reinforcing plate and the first reinforcing plate, the other side of the folding rod being slidably connected to the second reinforcing plate and the first reinforcing plate, and the output end of the spring rod extending to the folding rod and hinged to the folding rod;

[0011] As can be seen, in the above technical solution, when the pad is subjected to force, the first reinforcing plate is pressurized. The first reinforcing plate moves downward, causing the folding rod to fold, which in turn causes the spring rod to be compressed. Through the elasticity of the spring rod itself, the folding rod unfolds and pushes the second reinforcing plate upward, thereby buffering the pressure on the guide slide and the force-dispersing block and ensuring the quality of the workpiece being pressed and bonded.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared with existing technologies, the overall design of the pressurizing component is simple and the structure is reasonable. Through the corresponding cooperation of various structures, the pressure rod moves up and down, driving the connecting rod to move, which in turn enables the hinge seat to move the guide slide frame up and down, which in turn causes the force-dispersing block to move and pressurize the material.

[0014] Furthermore, the guide slide frame is slidably connected to the press body, which can guide and limit the displacement of the guide slide frame to ensure the stability of the guide slide frame during displacement. At the same time, the force dispersing block can also be finely adjusted in the fine-tuning arc groove, which makes it easy to distribute the pressure evenly on the workpiece and ensure the stability of the workpiece when pressurized.

[0015] Furthermore, when the pad is under force, it applies pressure to the first reinforcing plate. The first reinforcing plate moves downward, causing the folding rod to fold, which in turn causes the spring rod to be compressed. Through the elasticity of the spring rod itself, the folding rod unfolds and pushes the second reinforcing plate upward, thus buffering the pressure on the guide slide and the force-dispersing block and ensuring the quality of the workpiece's pressure fit.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1 - Figure 5 The composite machine pressure distribution uniformity and buffer structure shown uses a pressurizing component and a buffer component set on the press body 1. When the reinforcing rod 3 moves up and down, it drives the connecting rod 7 to move, which in turn causes the hinge seat 8 to move the guide slide frame 4 up and down, which in turn causes the force dispersing block 6 to move and pressurize the material. The guide slide frame 4 is slidably connected to the press body 1, which can guide and limit the movement of the guide slide frame 4 to ensure the stability of the guide slide frame 4 during movement. At the same time, the force dispersing block 6 can also be finely adjusted in the fine-tuning arc groove 5, which makes it easy to distribute the pressure evenly on the workpiece and ensure the stability of the workpiece during pressurization. The specific structural settings of the components are as follows.

[0025] The pressurizing assembly includes an eccentric shaft 2 located on the top of the press body 1. The eccentric shaft 2 is rotatably connected to the press body 1. A reinforcing pressure rod 3 is sleeved on the outer side of the eccentric shaft 2. A guide slide frame 4 is provided at the bottom of the reinforcing pressure rod 3.

[0026] The pressurizing assembly also includes a fine-tuning arc groove 5 at the bottom of the guide slide frame 4, a force-dispersing block 6 inserted in the fine-tuning arc groove 5, a connecting rod 7 threadedly connected to the bottom of the reinforcing rod 3, a hinge seat 8 hinged to the outside of the connecting rod 7, the hinge seat 8 extending to the guide slide frame 4 and detachably connected to the guide slide frame 4, the guide slide frame 4 being slidably connected to the press body 1, a drive motor 14 being bolted to one side of the top of the press body 1, a first pulley 15 being provided at the output end of the drive motor 14, a second pulley 16 being fixedly provided at one end of the eccentric shaft 2, and the first pulley 15 and the second pulley 16 being connected by belt drive;

[0027] The buffer assembly includes a pad 9 disposed at the bottom of the guide slide frame 4. A first reinforcing plate 10 is disposed at the bottom of the pad 9. The first reinforcing plate 10 is mounted on the press body 1 by bolts. A second reinforcing plate 11 is disposed at the top of the first reinforcing plate 10. A folding rod 12 is disposed between the second reinforcing plate 11 and the first reinforcing plate 10. A spring rod 13 is connected to one side of the bottom of the folding rod 12. One side of the folding rod 12 is located on the second reinforcing plate 11 and the first reinforcing plate 10 and is rotatably connected to the second reinforcing plate 11 and the first reinforcing plate 10. The other side of the folding rod 12 is slidably connected to the second reinforcing plate 11 and the first reinforcing plate 10. The output end of the spring rod 13 extends to the folding rod 12 and is hinged to the folding rod 12.

[0028] When using the above structure, the operator installs the device at the designated location. When pressurizing the workpiece, the workpiece is placed on the pad 9. The first pulley 15 is driven to rotate by the drive motor 14. The rotation of the first pulley 15 drives the second pulley 16 to rotate via the belt. When the second pulley 16 rotates, it drives the eccentric shaft 2 to rotate, so that the reinforcing pressure rod 3 can move up and down by the traction force of the rotation of the eccentric shaft 2. When the reinforcing pressure rod 3 moves up and down, it drives the connecting rod 7 to move, which in turn allows the hinge seat 8 to drive the guide slide frame 4 to move up and down, which in turn causes the force dispersing block 6 to move and pressurize the material.

[0029] Furthermore, the guide slide frame 4 is slidably connected to the press body 1, which can guide and limit the displacement of the guide slide frame 4 to ensure the stability of the guide slide frame 4 during displacement. At the same time, the force dispersing block 6 can also be finely adjusted in the fine-adjustment arc groove 5, which makes it easy to distribute the pressure evenly on the workpiece and ensure the stability of the workpiece when it is pressurized.

[0030] Furthermore, when the pad 9 is subjected to force, it applies pressure to the first reinforcing plate 10. The first reinforcing plate 10 moves downward, causing the folding rod 12 to fold, which in turn causes the spring rod 13 to be compressed. Through the elasticity of the spring rod 13 itself, the folding rod 12 unfolds and pushes the second reinforcing plate 11 upward, thereby buffering the pressure on the guide slide frame 4 and the force-releasing block 6 and ensuring the quality of the workpiece pressure fit.

[0031] Unlike existing technologies, this application discloses a pressure distribution uniformity and buffering structure for a composite machine. When the reinforcing rod 3 moves up and down, it drives the connecting rod 7 to move, which in turn allows the hinge seat 8 to drive the guide slide frame 4 to move up and down. This, in turn, causes the force-dispersing block 6 to move and pressurize the material. Furthermore, the guide slide frame 4 is slidably connected to the press body 1, which can guide and limit the movement of the guide slide frame 4 to ensure its stability. At the same time, the force-dispersing block 6 can also be finely adjusted within the fine-tuning arc groove 5, making it easy to distribute the pressure evenly on the workpiece and ensuring the stability of the workpiece during pressurization.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
